Familial hypercholesterolaemia (FH) is the most common autosomal dominant genetic condition, affecting about 1 in buy cialis with prescription 250 people, caused by a pathogenic variant in one of several genes involved in lipoprotein cholesterol catabolism. Treatment of elevated serum low-density lipoprotein cholesterol in people with FH substantially reduces the risk of ischaemic heart disease and cardiovascular mortality. Yet, the vast majority buy cialis with prescription of FH cases are undiagnosed and, thus, untreated.
Diagnosis is challenging because patients typically are asymptomatic, may not know their family history, are unaware of the seriousness of the diagnosis and may not even be seeing a physician regularly. In addition, the phenotypic diagnosis requires more than just serum cholesterol levels.In this issue of Heart, Carvalho and colleagues1 demonstrated the feasibility of the FH Case Ascertainment Tool (FAMCAT) for identifying patients likely to have FH in a cohort of 777â128 primary care patients in London. The FAMCAT score is based on systematic screening of routine primary care records for cholesterol measurements, age, triglycerides, family history, diabetes, kidney disease and current buy cialis with prescription use of lipid-lowering drugs (figure 1).
The use of FAMCAT to identify patients likely to have FH could ensure more accurate and rapid diagnosis (and subsequent treatment) for this group of patients at high risk of cardiovascular disease.Risk of familial hypercholesterolaemia (FH) in inner East London calculated using FAMCAT algorithm, assuming population prevalence of 1 in 500 and 1 in 250.

IHD, ischaemic heart disease. PP, population prevalence.A different approach to detection of FH was used by Brett and colleagues2 in a cohort of 232, 139 Australian general practice patients. Using a buy cialis with prescription pragmatic two-step approach, they first identified those at higher risk of FH using the TARB-Ex electronic screening tool.
Then, in the 1843 (0.8%) of patients identified electronically by TARB-Ex, clinical assessment by the physician was used to confirm a high FH risk the based on the phenotypic Dutch Lipid Clinic Network Criteria score. In a subset of 77 patients with FH, subsequent intensification of lipid-lowering therapy led to a further reduction in serum cholesterol levels .In an editorial, Qureshi and Patel3 summarise methods using the electronic health record (EHR) for improved diagnosis of FH (figure 2) and point out that the EHR approach often is limited by inadequate or missing data about family history, physical signs and other information. Cholesterol levels, while not diagnostic in isolation, are essential for buy cialis with prescription the diagnosis but may not have been measured in many asymptomatic individuals.
They conclude. ÂUltimately, successfully identifying the thousands of people with FH in the UK and abroad will require a system-wide approach from opportunistic identification at routine health encounters, systematic case finding in primary care, screening people at the time of a premature CVD event to childâparent screening and cascade testing.âPathway buy cialis with prescription to identification of FH from primary care.

IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1â13 Based on these studies, it has become clear that services and institutions still differ in the composition of the multidisciplinary teams that provide care for cialis generico en colombia patients who have a DSD.11 how to get prescribed cialis 14 Several projects have now worked to resolve this variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 âA systematic elucidation of differences of sex developmentâ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15â17 Another such initiative involved an update of the 2006 DSD consensus document by an international group of cialis generico en colombia professionals and patient representatives.18 These initiatives have highlighted how cultural and financial aspects and the availability of resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them. Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the Dutch-speaking Northern part of Belgium) have collaborated to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can be a reasonable approach for countries with similarly structured healthcare systems and similar cialis generico en colombia resources.
Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues. International networks such as the European Reference Network for rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind of collaboration across Europe.This paper cialis generico en colombia highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders. For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 21 Furthermore, informing patients and/or their parents about cialis generico en colombia atypical sex development and why this may warrant referral to a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section of the Dutch-Flemish guideline was written for these healthcare providers.
Moreover, this enables DSD specialists to refer to the guideline when advising a referral. Transition from cialis generico en colombia the prenatal to the postnatal team and from the paediatric to the adult team requires optimal communication between the specialists involved. Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue cialis generico en colombia is challenging and would benefit from international collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre group was formed with all members responsible for updating the literature for a specific part of the guideline.
Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory Document method described by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the rapid changes in testing cialis generico en colombia methods, for example, gene panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper. Abstracts had to be written in English and were identified using a broad range of Medical Subject Headings cialis generico en colombia terms (eg, DSD, genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care).
Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as cialis generico en colombia were articles that were not open access or retrievable through institutional access. Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft cialis generico en colombia was discussed by the writing committee and, after having obtained agreement on remaining points of discussion, revised into a final draft.
This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline. After receiving and incorporating their input, the final version cialis generico en colombia was presented to the paediatric and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening cialis generico en colombia of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed at the request of the parents.Another way DSD can be diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the genotypic sex and the phenotypic sex seen by ultrasound.
In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately. More often, the discrepancy will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which is now available to high-risk pregnant women in the Netherlands and to all pregnant women cialis generico en colombia in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus. However, depending on legal restrictions and/or ethical considerations, the X and cialis generico en colombia Y chromosomes are not always included in NIPT analysis and reports.
If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11â13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or atypical aspect of the genitalia will only cialis generico en colombia be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf a DSD is suspected, first-line sonographers and obstetricians should refer the couple to their colleague prenatal specialists working with or in a DSD team. After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on the ultrasound findings and the limitations of this technique cialis generico en colombia.
The procedure(s) that can be followed, including the risks associated with an amniocentesis. And the type cialis generico en colombia of information genetic testing can and cannot provide. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the childâs future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved. The clinical geneticist should be cialis generico en colombia experienced in prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available to allow parents to make a well-informed decision about whether or not to continue the pregnancy.
Termination of pregnancy can be considered, for instance, in a syndromic form of DSD with cialis generico en colombia multiple malformations, but when the DSD occurs as an apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered controversial by some, is legal in Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not cialis generico en colombia knowing exactly what the childâs genitalia will look like and uncertainty about the diagnosis, treatment and prognosis cannot be avoided completely. Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images.
In our experience, parents appreciate having already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of pregnant cialis generico en colombia couples decline prenatal testing (personal experience IALG, MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist. The terminology used in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, âyour babyâ) as long as sex assignment is pending.An algorithm for diagnostic cialis generico en colombia evaluation of a suspected DSD in the prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array.
It was recently estimated that >30% of individuals who have a DSD have additional structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, the geneticist can consider specific gene defects that may underlie cialis generico en colombia a known genetic syndrome or carry out NGS. NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parentsâ genetics.29â31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there is no tight time limit, cialis generico en colombia and we propose completing the analysis well before the expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition. Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.
The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their childâs sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers. A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline.
Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively. Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process. Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48âhours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

Conventional karyotyping can be useful. NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype. Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35â38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned.
Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences. If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilmsâ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing.
Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing. Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthorsâ institutions can be found on their respective websites. Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another.
This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions. What do laboratories report?.
How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity. It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype.
This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD. In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring.
This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41â44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise. For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium. We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15â17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48â50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time.
Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD. These should be published in widely available general medical journals and online, along with a national list of DSD centres. Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions.
One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved. A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.
This will enable highly individualised holistic care tailored to the patientâs needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15â17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication. Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing.
Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseasesâProject ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic.
In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5âyear survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation of endometrial tumours into four groups with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors. Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3â5% of cases.8â10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers. Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality.
Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation. We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2.
Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk. Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used.
Âendomet*â,âuter*â, âwombâ, âcancer(s)â, âneoplasm(s)â, âendometrium tumourâ, âcarcinomaâ, âadenosarcomaâ, âclear cell carcinomaâ, âcarcinosarcomaâ, âSNPâ, âsingle nucleotide polymorphismâ, âGWASâ, and âgenome-wide association study/iesâ. No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion.
Chronbachâs α score was calculated between reviewers and indicated high consistency at 0.92. Caseâcontrol, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected. For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected.
Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95%âCI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis. For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5Ã10-8, indicating genome-wide significance, was accepted as statistically significant.
However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1Ã10-5, allowing for marginally significant SNPs to be included. As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs. The PRS was assumed to have a Normal distribution, with mean 2âβipI and SE, Ï, equal to â2âβi2pI(1âpi), according to the binomial distribution, where the summation is over all SNPs in the risk score.
Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01Ï), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis. Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported.
Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21â25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21â25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies. Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28â30 Moreover, a recent article authored by OâMara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations.
Those having a multi-ethnic cohort also consisted primarily of broad European populations. Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene. Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene.
The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95%âCI 1.32 to 2.04. P=9.6Ã10-6) compared with the endometrioid arm (OR 1.25, 95%âCI 1.14 to 1.38. P=4.7Ã10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. OâMara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86Ã10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis.
It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer. These can be activated by high levels of KLF5 (transcriptional activator).
Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95%âCI 1.11 to 1.21. P=4.83Ã10-11), the A allele of rs9600103 (OR 1.23, 95%âCI 1.16 to 1.30. P=3.76Ã10-12) and C allele of rs7981863 (OR 1.16, 95%âCI 1.12 to 1.20.
P=2.70Ã10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated. The recent GWAS by OâMara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5Ã10â8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele.
Two more original studies were identified through our full-text evaluation. However, these were not included here as they did not meet our inclusion criteriaâone due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses. However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13â000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry.
There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42â44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer. We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant.
The largest GWAS conducted in this field was the discovery- and meta-GWAS by OâMara et al, which utilised 12â096 cases and 108â979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer. For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200â000 individuals with more than half being cases, and resulted in identification of ~170âSNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150â000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS. The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s.
However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95%âCI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality. Thus, these should be interpreted with caution.
Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by OâMara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants. However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs.
It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data. This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data.
Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene. In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit. In order to elucidate biologically relevant candidate target genes in endometrial cancer, OâMara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS.
Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1. Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14. In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A.
This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes. The study looked at proteinâprotein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.
Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women. This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans.
This poses a problem for developing risk prediction models that are equally valuable and predictive across populations. Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours. Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer.
It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes. It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhmanâs classification system, type I versus type II, or no histological classification system at all. Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk.
Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations. Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk.
The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..
IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1â13 Based on these studies, it has become clear that services and institutions still differ in the composition of the multidisciplinary teams that provide buy cialis with prescription care for patients who have a DSD.11 14 Several projects have now worked to resolve this variability in Recommended Site care. The European Cooperation in Science and Technology (EU COST) action BM1303 âA systematic elucidation of differences of sex developmentâ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15â17 Another such initiative involved an update of the 2006 DSD consensus document by an international group of professionals and patient representatives.18 These initiatives have buy cialis with prescription highlighted how cultural and financial aspects and the availability of resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them. Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the Dutch-speaking Northern part of Belgium) have collaborated to produce a buy cialis with prescription detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can be a reasonable approach for countries with similarly structured healthcare systems and similar resources. Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues.
International networks such as the European Reference Network for rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion buy cialis with prescription of this kind of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders. For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 21 Furthermore, informing patients and/or their parents about atypical sex development and why this may warrant referral to a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section of the Dutch-Flemish guideline buy cialis with prescription was written for these healthcare providers. Moreover, this enables DSD specialists to refer to the guideline when advising a referral. Transition from the prenatal to the postnatal team and from the buy cialis with prescription paediatric to the adult team requires optimal communication between the specialists involved.
Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue is challenging and would benefit from international collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre group was buy cialis with prescription formed with all members responsible for updating the literature for a specific part of the guideline. Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory buy cialis with prescription Document method described by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the rapid changes in testing methods, for example, gene panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper.
Abstracts had to be written in English and were identified using a broad range of Medical Subject buy cialis with prescription Headings terms (eg, DSD, genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care). Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as were articles that were not open access or buy cialis with prescription retrievable through institutional access. Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft was discussed by the writing committee and, after having obtained agreement on buy cialis with prescription remaining points of discussion, revised into a final draft.
This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline. After receiving and incorporating their buy cialis with prescription input, the final version was presented to the paediatric and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed buy cialis with prescription at the request of the parents.Another way DSD can be diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the genotypic sex and the phenotypic sex seen by ultrasound. In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately.
More often, the discrepancy buy cialis with prescription will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which is now available to high-risk pregnant women in the Netherlands and to all pregnant women in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus. However, depending on legal restrictions and/or ethical considerations, the X and Y chromosomes are not always included buy cialis with prescription in NIPT analysis and reports. If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11â13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or atypical aspect of the genitalia will only be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf a DSD is suspected, first-line sonographers and obstetricians should refer buy cialis with prescription the couple to their colleague prenatal specialists working with or in a DSD team.
After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on the ultrasound findings and the limitations of this technique buy cialis with prescription. The procedure(s) that can be followed, including the risks associated with an amniocentesis. And the type of information genetic testing buy cialis with prescription can and cannot provide. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the childâs future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved.
The clinical geneticist should be experienced in buy cialis with prescription prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available to allow parents to make a well-informed decision about whether or not to continue the pregnancy. Termination of pregnancy can be considered, for instance, in a syndromic form of DSD with multiple malformations, but when the DSD occurs as an buy cialis with prescription apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered controversial by some, is legal in Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not knowing exactly what the childâs genitalia will look like and uncertainty about the diagnosis, treatment and prognosis cannot buy cialis with prescription be avoided completely. Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images.
In our experience, parents appreciate having already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of pregnant couples decline prenatal testing (personal experience IALG, buy cialis with prescription MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist. The terminology used buy cialis with prescription in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, âyour babyâ) as long as sex assignment is pending.An algorithm for diagnostic evaluation of a suspected DSD in the prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array. It was recently estimated that >30% of individuals who have a DSD have additional structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, buy cialis with prescription the geneticist can consider specific gene defects that may underlie a known genetic syndrome or carry out NGS.
NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parentsâ genetics.29â31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there is no tight time limit, buy cialis with prescription and we propose completing the analysis well before the expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition. Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.
The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their childâs sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers. A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline. Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively.
Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process. Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48âhours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype. Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35â38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned. Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences.
If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilmsâ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing. Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing. Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthorsâ institutions can be found on their respective websites.
Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another. This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions. What do laboratories report?.
How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity. It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype. This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD.
In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring. This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41â44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise.
For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium. We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15â17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48â50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time. Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD. These should be published in widely available general medical journals and online, along with a national list of DSD centres.
Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions. One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved. A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.
This will enable highly individualised holistic care tailored to the patientâs needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15â17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication. Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing. Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseasesâProject ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic. In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5âyear survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation of endometrial tumours into four groups how to get prescribed cialis with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors. Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3â5% of cases.8â10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers.
Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality. Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation.
We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2. Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk. Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used.
Âendomet*â,âuter*â, âwombâ, âcancer(s)â, âneoplasm(s)â, âendometrium tumourâ, âcarcinomaâ, âadenosarcomaâ, âclear cell carcinomaâ, âcarcinosarcomaâ, âSNPâ, âsingle nucleotide polymorphismâ, âGWASâ, and âgenome-wide association study/iesâ. No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion. Chronbachâs α score was calculated between reviewers and indicated high consistency at 0.92.
Caseâcontrol, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected. For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected. Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95%âCI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis.
For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5Ã10-8, indicating genome-wide significance, was accepted as statistically significant. However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1Ã10-5, allowing for marginally significant SNPs to be included. As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs.
The PRS was assumed to have a Normal distribution, with mean 2âβipI and SE, Ï, equal to â2âβi2pI(1âpi), according to the binomial distribution, where the summation is over all SNPs in the risk score. Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01Ï), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis. Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported.
Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21â25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21â25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies. Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28â30 Moreover, a recent article authored by OâMara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations. Those having a multi-ethnic cohort also consisted primarily of broad European populations.
Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene. Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene. The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95%âCI 1.32 to 2.04. P=9.6Ã10-6) compared with the endometrioid arm (OR 1.25, 95%âCI 1.14 to 1.38.
P=4.7Ã10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. OâMara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86Ã10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis. It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer.
These can be activated by high levels of KLF5 (transcriptional activator). Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95%âCI 1.11 to 1.21. P=4.83Ã10-11), the A allele of rs9600103 (OR 1.23, 95%âCI 1.16 to 1.30. P=3.76Ã10-12) and C allele of rs7981863 (OR 1.16, 95%âCI 1.12 to 1.20.
P=2.70Ã10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated. The recent GWAS by OâMara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5Ã10â8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele. Two more original studies were identified through our full-text evaluation.
However, these were not included here as they did not meet our inclusion criteriaâone due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses. However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13â000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry. There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42â44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer.
We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant. The largest GWAS conducted in this field was the discovery- and meta-GWAS by OâMara et al, which utilised 12â096 cases and 108â979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer. For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200â000 individuals with more than half being cases, and resulted in identification of ~170âSNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150â000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS.
The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s. However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95%âCI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality. Thus, these should be interpreted with caution.
Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by OâMara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants. However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs. It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data.
This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data. Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene.
In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit. In order to elucidate biologically relevant candidate target genes in endometrial cancer, OâMara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS. Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1. Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14.
In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A. This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes. The study looked at proteinâprotein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.
Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women. This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans. This poses a problem for developing risk prediction models that are equally valuable and predictive across populations.
Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours. Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer. It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes. It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhmanâs classification system, type I versus type II, or no histological classification system at all.
Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk. Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations.
Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk. The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..

The team of Deputy and Associate Editors Heribert Schunkert, Sharlene Day and Peter SchwartzThe European Heart Journal (EHJ) best time of day to take cialis for bph wants to attract high-class submissions dealing with genetic findings that help to improve the mechanistic understanding and the therapy of cardiovascular diseases. In charge of identifying such articles is a mini-team of experts on genetics, Heribert Schunkert, Sharlene Day, and Peter Schwartz.Genetic findings have contributed enormously to the molecular understanding of cardiovascular diseases. A number best time of day to take cialis for bph of diseases including various channelopathies, cardiomyopathies, and metabolic disorders have been elucidated based on a monogenic inheritance and the detection of disease-causing mutations in large families.
More recently, the complex genetic architecture of common cardiovascular diseases such as atrial fibrillation or coronary artery disease has become increasingly clear. Moreover, genetics became a sensitive tool to characterize best time of day to take cialis for bph the role of traditional cardiovascular risk factors in the form of Mendelian randomized studies. However, the real challenge is still ahead, i.e., to bridge genetic findings into novel therapies for the prevention and treatment of cardiac diseases.

Described as the âsingle largest unmet best time of day to take cialis for bph need in cardiovascular medicineâ, heart failure with preserved ejection fraction (HFpEF) remains an untreatable disease currently representing 65% of new HF diagnoses. HFpEF is more frequent among women and is associated with a poor prognosis and unsustainable healthcare costs.1,2 Moreover, the variability in HFpEF phenotypes amplifies the complexity and difficulties of the approach.3â5 In this perspective, unveiling novel molecular targets is imperative. In a State of the Art Review article entitled âLeveraging clinical epigenetics in heart failure with preserved ejection fraction.
A call for individualized therapiesâ, authored by Francesco Paneni from the University of Zurich in Switzerland, and colleagues,6 the authors note that epigenetic modificationsâdefined as changes of DNA, histones, and non-coding RNAs (ncRNAs)ârepresent a molecular framework through which the environment modulates gene best time of day to take cialis for bph expression.6 Epigenetic signals acquired over a lifetime lead to chromatin remodelling and affect transcriptional programmes underlying oxidative stress, inflammation, dysmetabolism, and maladaptive left ventricular (LV) remodelling, all conditions predisposing to HFpEF. The strong involvement of epigenetic signalling in this setting makes the epigenetic information relevant for diagnostic and therapeutic purposes in patients with HFpEF. The recent advances in high-throughput sequencing, computational epigenetics, and machine learning have enabled the identification of reliable epigenetic biomarkers in cardiovascular best time of day to take cialis for bph patients.
In contrast to genetic tools, epigenetic biomarkers mirror the contribution of environmental cues and lifestyle changes, and their reversible nature offers a promising opportunity to monitor disease states. The growing understanding of chromatin and ncRNA biology has led to the development of several Food and Drug Administration (FDA)-approved âepi-drugsâ (chromatin modifiers, mimics, and anti-miRs) able to prevent transcriptional alterations underpinning LV remodelling best time of day to take cialis for bph and HFpEF. In the present review, Paneni and colleagues discuss the importance of clinical epigenetics as a new tool to be employed for a personalized management of HFpEF.Sick sinus syndrome (SSS) is a complex cardiac arrhythmia and the leading indication for permanent pacemaker implantation worldwide.
It is characterized by pathological sinus bradycardia, sinoatrial block, or alternating atrial brady- best time of day to take cialis for bph and tachyarrhythmias. Symptoms include fatigue, reduced exercise capacity, and syncope. Few studies have been conducted on the basic mechanisms of SSS, and therapeutic limitations reflect an incomplete understanding of the pathophysiology.7 In a clinical research entitled âGenetic insight into sick sinus syndromeâ, Rosa Thorolfsdottir from deCODE genetics in Reykjavik, Iceland, and colleagues aimed to use human genetics to investigate the pathogenesis of SSS and the role of risk factors in its development.8 The authors performed a genome-wide association study (GWAS) of >6000 SSS cases and >1 000 000 controls best time of day to take cialis for bph.
Variants at six loci associated with SSS. A full genotypic model best described the p.Gly62Cys association, with an odds ratio (OR) of 1.44 for heterozygotes and a disproportionally large OR of 13.99 for homozygotes. All the best time of day to take cialis for bph SSS variants increased the risk of pacemaker implantation.
Their association with atrial fibrillation (AF) varied, and p.Gly62Cys was the only variant not associating with any other arrhythmia or cardiovascular disease. They also tested 17 exposure phenotypes best time of day to take cialis for bph in polygenic score (PGS) and Mendelian randomization analyses. Only two associated with risk of SSS in Mendelian randomizationâAF and lower heart rateâsuggesting causality.
Powerful PGS analyses provided convincing evidence against causal best time of day to take cialis for bph associations for body mass index, cholesterol, triglycerides, and type 2 diabetes (P >. 0.05) (Figure 1).

Variants at six loci (named by corresponding gene names) were identified through genome-wide association study (GWAS), and their unique phenotypic associations provide insight into distinct pathways underlying SSS. Investigation of best time of day to take cialis for bph the role of risk factors in SSS development supported a causal role for atrial fibrillation (AF) and heart rate, and provided convincing evidence against causality for body mass index (BMI), cholesterol (HDL and non-HDL), triglycerides, and type 2 diabetes (T2D).

Mendelian randomization supports a causal role for AF in the development of SSS.

The disease is caused by mutations in the dystrophin gene, which lead to dystrophin deficiency in muscle cells, resulting in decreased fibre stability and continued degeneration. The patients present with progressive muscle wasting and loss of muscle function, develop restrictive respiratory failure and dilated cardiomyopathy, and usually die in their late teens or twenties from cardiac or respiratory failure.10 In a clinical research article âAssociation between prophylactic angiotensin-converting enzyme inhibitors and overall best time of day to take cialis for bph survival in Duchenne muscular dystrophy.
Analysis of registry dataâ Raphaël Porcher from the Université de Paris in France, and colleagues estimate the effect of prophylactic angiotensin-converting enzyme (ACE) inhibitors on survival in DMD.11 The authors analysed the data from the French multicentre DMD-Heart-Registry. They estimated the association between the prophylactic prescription of ACE inhibitors and event-free survival in 668 patients between the ages of 8 and 13 years, with normal left ventricular function, using (i) a Cox model with intervention as a best time of day to take cialis for bph time-dependent covariate. (ii) a propensity-based analysis comparing ACE inhibitor treatment vs.
No treatment best time of day to take cialis for bph. And (iii) a set of sensitivity analyses. The study outcomes were (i) overall survival and (ii) hospitalizations for HF or acute respiratory failure.
Among the patients included in the DMD-Heart-Registry, 576 were eligible for this study, of whom 390 were treated with an ACE inhibitor prophylactically best time of day to take cialis for bph. Death occurred in 53 patients (13.5%) who were and 60 patients (32.3%) who were not treated prophylactically with an ACE inhibitor. In a Cox model, with intervention as a time-dependent variable, the hazard ratio (HR) associated with ACE inhibitor treatment was 0.49 for overall mortality after adjustment for baseline variables best time of day to take cialis for bph.
In the propensity-based analysis, with 278 patients included in the treatment group and 302 in the control group, ACE inhibitors were associated with a lower risk of death (HR 0.32) and hospitalization for HF (HR 0.16) (Figure 2). All sensitivity analyses yielded similar results best time of day to take cialis for bph.

Conclude that prophylactic treatment with ACE inhibitors in DMD is associated with a significantly higher overall survival and lower rate of hospitalization for management of HF. The manuscript is accompanied by an Editorial by Mariell Jessup and colleagues from the American Heart Association in Dallas, Texas, USA.12 The authors describe how cardioprotective strategies have been investigated in a number of cardiovascular disorders and successfully incorporated into treatment regimens for selected patients, including ACE inhibitors in patients with and without diabetes and coronary artery disease, angiotensin receptor blockers best time of day to take cialis for bph and beta-blockers in Marfan syndrome, and ACE inhibitors and beta-blockers in patients at risk for chemotherapy-related toxicity.

Patients with HCM may experience atrial and ventricular arrhythmias and HF. However, disease expression best time of day to take cialis for bph and severity are highly variable.
Furthermore, there is marked diversity in the age of diagnosis. Although childhood-onset disease is well documented, it is far less best time of day to take cialis for bph common. Owing to its rarity, the natural history of childhood-onset HCM is not well characterized.12â14 In a clinical research article entitled âClinical characteristics and outcomes in childhood-onset hypertrophic cardiomyopathyâ, Nicholas Marston from the Harvard Medical School in Boston, MA, USA, and colleagues aimed to describe the characteristics and outcomes of childhood-onset HCM.15 They performed an observational cohort study of >7500 HCM patients.
HCM patients were stratified by age at diagnosis [<1 year (infancy), 1â18 years (childhood), >18 years (adulthood)] and assessed for composite endpoints including HF, life-threatening ventricular arrhythmias, AF, and an overall composite that also included stroke and death. Stratifying by age of best time of day to take cialis for bph diagnosis, 2.4% of patients were diagnosed in infancy, 14.7% in childhood, and 2.9% in adulthood. Childhood-onset HCM patients had an â¼2%/year event rate for the overall composite endpoint, with ventricular arrhythmias representing the most common event in the first decade following the baseline visit, and HF and AF more common by the end of the second decade.
Sarcomeric HCM was more common in childhood-onset HCM (63%) and carried a best time of day to take cialis for bph worse prognosis than non-sarcomeric disease, including a >2-fold increased risk of HF and 67% increased risk of the overall composite outcome. When compared with adult-onset HCM, those with childhood-onset disease were 36% more likely to develop life-threatening ventricular arrhythmias and twice as likely to require transplant or a ventricular assist device.The authors conclude that patients with childhood-onset HCM are more likely to have sarcomeric disease, carry a higher risk of life-threatening ventricular arrythmias, and have greater need for advanced HF therapies. The manuscript is accompanied by an Editorial by Juan Pablo Kaski from the University College London (UCL) Institute of Cardiovascular Science in London, UK.16 Kaski concludes that the field of HCM best time of day to take cialis for bph is now entering the era of personalized medicine, with the advent of gene therapy programmes and a focus on treatments targeting the underlying pathophysiology.
Pre-clinical data suggesting that small molecule myosin inhibitors may attenuate or even prevent disease expression provide cause for optimism, and nowhere more so than for childhood-onset HCM. An international collaborative approach involving basic, translational, and clinical science is now needed to characterize disease expression and progression and develop novel therapies for childhood HCM.Dilated cardiomyopathy best time of day to take cialis for bph (DCM) is a heart muscle disease characterized by LV dilatation and systolic dysfunction in the absence of abnormal loading conditions or coronary artery disease. It is a major cause of systolic HF, the leading indication for heart transplantation, and therefore a major public health problem due to the important cardiovascular morbidity and mortality.17,18 Understanding of the genetic basis of DCM has improved in recent years, with a role for both rare and common variants resulting in a complex genetic architecture of the disease.
In a translational research article entitled âGenome-wide association analysis in dilated best time of day to take cialis for bph cardiomyopathy reveals two new players in systolic heart failure on chromosomes 3p25.1 and 22q11.23â, Sophie Garnier from the Sorbonne Université in Paris, France, and colleagues conducted the largest genome-wide association study performed so far in DCM, with >2500 cases and >4000 controls in the discovery population.19 They identified and replicated two new DCM-associated loci, on chromosome 3p25.1 and chromosome 22q11.23, while confirming two previously identified DCM loci on chromosomes 10 and 1, BAG3 and HSPB7. A PGS constructed from the number of risk alleles at these four DCM loci revealed a 27% increased risk of DCM for individuals with eight risk alleles compared with individuals with five risk alleles (median of the referral population). In silico annotation and functional 4C-sequencing analysis on induced pluripotent stem cell (iPSC)-derived cardiomyocytes identified SLC6A6 as the most likely DCM gene at the 3p25.1 locus.
This gene encodes a taurine transporter whose involvement in myocardial dysfunction and DCM is supported by numerous observations in humans and animals best time of day to take cialis for bph. At the 22q11.23 locus, in silico and data mining annotations, and to a lesser extent functional analysis, strongly suggested SMARCB1 as the candidate culprit gene.Garnier et al. Conclude that their best time of day to take cialis for bph study provides a better understanding of the genetic architecture of DCM and sheds light on novel biological pathways underlying HF.
The manuscript is accompanied by an Editorial by Elizabeth McNally from the Northwestern University Feinberg School of Medicine in Chicago, USA, and colleagues.20 The authors conclude that methods to integrate common and rare genetic information will continue to evolve and provide insight on disease progression, potentially providing biomarkers and clues for useful therapeutic pathways to guide drug development. At present, best time of day to take cialis for bph rare cardiomyopathy variants have clinical utility in predicting risk, especially arrhythmic risk. PGS analyses for HF or DCM progression are expected to come to clinical use, especially with the addition of broader GWAS-derived data.
Combining genetic risk data with clinical and social determinants should help identify those at greatest risk, offering the opportunity best time of day to take cialis for bph for risk reduction.In a Special Article entitled âInfluenza vaccination. A âshotâ at INVESTing in cardiovascular healthâ, Scott Solomon from the Brigham and Womenâs Hospital, Harvard Medical School in Boston, MA, USA, and colleagues note that the link between viral respiratory and non-pulmonary organ-specific injury has become increasingly appreciated during the current erectile dysfunction disease 2019 (erectile dysfunction treatment) cialis.21 Even prior to the cialis, however, the association between acute with influenza and elevated cardiovascular risk was evident. The recently published best time of day to take cialis for bph results of the NHLBI-funded INVESTED trial, a 5200-patient comparative effectiveness study of high-dose vs.
Standard-dose influenza treatment to reduce cardiopulmonary events and mortality in a high-risk cardiovascular population, found no difference between strategies. However, the broader implications of influenza treatment as a strategy to reduce morbidity in high-risk patients remains extremely important, with randomized control trial and observational data supporting vaccination in high-risk patients with cardiovascular disease. Given a favourable riskâbenefit profile and widespread availability best time of day to take cialis for bph at generally low cost, the authors contend that influenza vaccination should remain a centrepiece of cardiovascular risk mitigation and describe the broader context of underutilization of this strategy.
Few therapeutics in medicine offer seasonal efficacy from a single administration with generally mild, transient side effects and exceedingly low rates of serious adverse effects. control measures such as physical distancing, hand washing, and the use of masks during the erectile dysfunction treatment cialis best time of day to take cialis for bph have already been associated with substantially curtailed incidence of influenza outbreaks across the globe. Appending annual influenza vaccination to these measures represents an important public health and moral imperative.The issue is complemented by two Discussion Forum articles.

The team of Deputy and Associate Editors Heribert Schunkert, Sharlene Day and Peter SchwartzThe buy cialis with prescription European Heart Journal (EHJ) wants to attract high-class submissions dealing with genetic findings that help to improve the mechanistic understanding and the therapy of cardiovascular diseases. In charge of identifying such articles is a mini-team of experts on genetics, Heribert Schunkert, Sharlene Day, and Peter Schwartz.Genetic findings have contributed enormously to the molecular understanding of cardiovascular diseases. A number of diseases including various channelopathies, cardiomyopathies, and metabolic disorders have been elucidated based on a monogenic inheritance and the detection of disease-causing buy cialis with prescription mutations in large families. More recently, the complex genetic architecture of common cardiovascular diseases such as atrial fibrillation or coronary artery disease has become increasingly clear. Moreover, genetics became a sensitive tool to characterize the role of traditional cardiovascular risk factors buy cialis with prescription in the form of Mendelian randomized studies.
However, the real challenge is still ahead, i.e., to bridge genetic findings into novel therapies for the prevention and treatment of cardiac diseases. The full cycle from identification of a family with hypercholesterolaemia due to a proprotein convertase subtilisin/kexin type 9 (PCSK-9) mutation to successful risk lowering by PCSK-9 antibodies illustrates the buy cialis with prescription power of genetics in this regard.With its broad expertise, the new EHJ editorial team on genetics aims to cover manuscripts from all areas in which genetics may contribute to the understanding of cardiovascular diseases. Prof. Peter Schwartz buy cialis with prescription is a world-class expert on channelopathies and pioneered the field of long QT syndrome. He is an experienced clinical specialist on cardiac arrhythmias of genetic origins and a pioneer in the electrophysiology of the myocardium.
He studied in Milan, worked at the University of Texas for 3âyears and, as Associate Professor, at the University of Oklahoma 4âmonths/year for 12âyears. He has been Chairman buy cialis with prescription of Cardiology at the University of Pavia for 20âyears and since 1999 acts as an extraordinary professor at the Universities of Stellenbosch and Cape Town for 3âmonths/year.Prof. Sharlene M. Day is Director of Translational Research in the Division of Cardiovascular Medicine and Cardiovascular Institute buy cialis with prescription at the University of Pennsylvania. She trained at the University of Michigan and stayed on as faculty as the founding Director of the Inherited Cardiomyopathy and Arrhythmia Program before moving to the University of Pennsylvania in 2019.
Like Prof buy cialis with prescription. Schwartz, her research programme covers the full spectrum from clinical medicine to basic research with a focus on hypertrophic cardiomyopathy. Both she buy cialis with prescription and Prof. Schwartz have developed inducible pluripotent stem cell models of human monogenic cardiac disorders as a platform to study the underlying biological mechanisms of disease.Heribert Schunkert is Director of the Cardiology Department in the German Heart Center Munich. He trained in the Universities of Aachen and Regensburg, Germany buy cialis with prescription and for 4 years in various teaching hospitals in Boston.
Before moving to Munich, he was Director of the Department for Internal Medicine at the University Hospital in Lübeck. His research interest shifted from the molecular biology of the reninâangiotensin system to complex genetics of atherosclerosis. He was amongst the first to conduct buy cialis with prescription genome-wide association meta-analyses, which allowed the identification of numerous genetic variants that contribute to coronary artery disease, peripheral arterial disease, or aortic stenosis.The editorial team on cardiovascular genetics aims to facilitate the publication of strong translational research that illustrates to clinicians and cardiovascular scientists how genetic and epigenetic variation influences the development of heart diseases. The future perspective is to communicate genetically driven therapeutic targets as has become evident already with the utilization of interfering antibodies, RNAs, or even genome-editing instruments.In this respect, the team encourages submission of world-class genetic research on the cardiovascular system to the EHJ. The team buy cialis with prescription is also pleased to cooperate with the novel Council on Cardiovascular Genomics which was inaugurated by the ESC in 2020.Conflict of interest.

Described as the âsingle largest unmet need in cardiovascular medicineâ, heart buy cialis with prescription failure with preserved ejection fraction (HFpEF) remains an untreatable disease currently representing 65% of new HF diagnoses. HFpEF is more frequent among women and is associated with a poor prognosis and unsustainable healthcare costs.1,2 Moreover, the variability in HFpEF phenotypes amplifies the complexity and difficulties of the approach.3â5 In this perspective, unveiling novel molecular targets is imperative. In a State of the Art Review article entitled âLeveraging clinical epigenetics in heart failure with preserved ejection fraction. A call for buy cialis with prescription individualized therapiesâ, authored by Francesco Paneni from the University of Zurich in Switzerland, and colleagues,6 the authors note that epigenetic modificationsâdefined as changes of DNA, histones, and non-coding RNAs (ncRNAs)ârepresent a molecular framework through which the environment modulates gene expression.6 Epigenetic signals acquired over a lifetime lead to chromatin remodelling and affect transcriptional programmes underlying oxidative stress, inflammation, dysmetabolism, and maladaptive left ventricular (LV) remodelling, all conditions predisposing to HFpEF. The strong involvement of epigenetic signalling in this setting makes the epigenetic information relevant for diagnostic and therapeutic purposes in patients with HFpEF.
The recent advances in high-throughput sequencing, computational epigenetics, and machine learning buy cialis with prescription have enabled the identification of reliable epigenetic biomarkers in cardiovascular patients. In contrast to genetic tools, epigenetic biomarkers mirror the contribution of environmental cues and lifestyle changes, and their reversible nature offers a promising opportunity to monitor disease states. The growing understanding of chromatin and ncRNA biology has led to the buy cialis with prescription development of several Food and Drug Administration (FDA)-approved âepi-drugsâ (chromatin modifiers, mimics, and anti-miRs) able to prevent transcriptional alterations underpinning LV remodelling and HFpEF. In the present review, Paneni and colleagues discuss the importance of clinical epigenetics as a new tool to be employed for a personalized management of HFpEF.Sick sinus syndrome (SSS) is a complex cardiac arrhythmia and the leading indication for permanent pacemaker implantation worldwide. It is characterized by pathological sinus bradycardia, buy cialis with prescription sinoatrial block, or alternating atrial brady- and tachyarrhythmias.
Symptoms include fatigue, reduced exercise capacity, and syncope. Few studies have been conducted on the basic mechanisms of SSS, buy cialis with prescription and therapeutic limitations reflect an incomplete understanding of the pathophysiology.7 In a clinical research entitled âGenetic insight into sick sinus syndromeâ, Rosa Thorolfsdottir from deCODE genetics in Reykjavik, Iceland, and colleagues aimed to use human genetics to investigate the pathogenesis of SSS and the role of risk factors in its development.8 The authors performed a genome-wide association study (GWAS) of >6000 SSS cases and >1 000 000 controls. Variants at six loci associated with SSS. A full genotypic model best described the p.Gly62Cys association, with an odds ratio (OR) of 1.44 for heterozygotes and a disproportionally large OR of 13.99 for homozygotes. All the SSS variants increased the risk of pacemaker buy cialis with prescription implantation.
Their association with atrial fibrillation (AF) varied, and p.Gly62Cys was the only variant not associating with any other arrhythmia or cardiovascular disease. They also tested 17 exposure phenotypes in polygenic score (PGS) and Mendelian randomization analyses buy cialis with prescription. Only two associated with risk of SSS in Mendelian randomizationâAF and lower heart rateâsuggesting causality. Powerful PGS analyses provided convincing evidence against causal associations for buy cialis with prescription body mass index, cholesterol, triglycerides, and type 2 diabetes (P >. 0.05) (Figure 1).
Figure 1Summary of genetic insight into the buy cialis with prescription pathogenesis of sick sinus syndrome (SSS) and the role of risk factors in its development. Variants at six loci (named by corresponding gene names) were identified through genome-wide association study (GWAS), and their unique phenotypic associations provide insight into distinct pathways underlying SSS. Investigation of the role of risk factors in SSS development supported a causal role buy cialis with prescription for atrial fibrillation (AF) and heart rate, and provided convincing evidence against causality for body mass index (BMI), cholesterol (HDL and non-HDL), triglycerides, and type 2 diabetes (T2D). Mendelian randomization did not support causality for coronary artery disease, ischaemic stroke, heart failure, PR interval, or QRS duration (not shown in the figure).

Conclude that buy cialis with prescription they report the associations of variants at six loci with SSS, including a missense variant in KRT8 that confers high risk in homozygotes and points to a mechanism specific to SSS development. Mendelian randomization supports a causal role for AF in the development of SSS.
The article is accompanied by an Editorial by Stefan Kääb from LMU Klinikum in Munich, Germany, and colleagues.9 The authors conclude that the limitations of the work challenge clinical translation, but do not diminish the multiple interesting findings of Thorolfsdottir et al., bringing us closer to the finishing line of unlocking SSS genetics to develop new therapeutic strategies. They also highlight that buy cialis with prescription this study represents a considerable accomplishment for the field, but also clearly highlights upcoming challenges and indicates areas where further research is warranted on our way on the translational road to personalized medicine.Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder that affects â¼1 in every 3500 live-born male infants, making it the most common neuromuscular disease of childhood. The disease is caused by mutations in the dystrophin gene, which lead to dystrophin deficiency in muscle cells, resulting in decreased fibre stability and continued degeneration. The patients present with progressive muscle wasting and loss of muscle function, develop restrictive respiratory failure and dilated cardiomyopathy, and usually die in their late teens or twenties from cardiac or respiratory failure.10 In a clinical buy cialis with prescription research article âAssociation between prophylactic angiotensin-converting enzyme inhibitors and overall survival in Duchenne muscular dystrophy. Analysis of registry dataâ Raphaël Porcher from the Université de Paris in France, and colleagues estimate the effect of prophylactic angiotensin-converting enzyme (ACE) inhibitors on survival in DMD.11 The authors analysed the data from the French multicentre DMD-Heart-Registry.
They estimated the association between the prophylactic prescription of ACE inhibitors and event-free survival in 668 patients between the ages of 8 and 13 years, with normal left ventricular function, buy cialis with prescription using (i) a Cox model with intervention as a time-dependent covariate. (ii) a propensity-based analysis comparing ACE inhibitor treatment vs. No treatment buy cialis with prescription. And (iii) a set of sensitivity analyses. The study outcomes were (i) overall survival and (ii) hospitalizations for HF or acute respiratory failure.
Among the patients included in the DMD-Heart-Registry, 576 were eligible for this buy cialis with prescription study, of whom 390 were treated with an ACE inhibitor prophylactically. Death occurred in 53 patients (13.5%) who were and 60 patients (32.3%) who were not treated prophylactically with an ACE inhibitor. In a Cox model, with intervention as a time-dependent variable, the hazard ratio (HR) associated with ACE inhibitor treatment buy cialis with prescription was 0.49 for overall mortality after adjustment for baseline variables. In the propensity-based analysis, with 278 patients included in the treatment group and 302 in the control group, ACE inhibitors were associated with a lower risk of death (HR 0.32) and hospitalization for HF (HR 0.16) (Figure 2). All sensitivity analyses buy cialis with prescription yielded similar results.

Analysis of registry data. See pages buy cialis with prescription 1976â1984.).Porcher et al. Conclude that prophylactic treatment with ACE inhibitors in DMD is associated with a significantly higher overall survival and lower rate of hospitalization for management of HF. The manuscript is accompanied by an Editorial by Mariell Jessup and colleagues from the American Heart Association in Dallas, Texas, USA.12 The authors describe how cardioprotective strategies have been investigated in a number of cardiovascular disorders buy cialis with prescription and successfully incorporated into treatment regimens for selected patients, including ACE inhibitors in patients with and without diabetes and coronary artery disease, angiotensin receptor blockers and beta-blockers in Marfan syndrome, and ACE inhibitors and beta-blockers in patients at risk for chemotherapy-related toxicity. They conclude that Porcher et al.
Have now convincingly demonstrated that even very young patients with DMD buy cialis with prescription can benefit from the life-saving intervention of ACE inhibition.Hypertrophic cardiomyopathy (HCM) is characterized by unexplained LV hypertrophy and often caused by pathogenic variants in genes that encode the sarcomere apparatus. Patients with HCM may experience atrial and ventricular arrhythmias and HF. However, disease expression and severity are highly buy cialis with prescription variable. Furthermore, there is marked diversity in the age of diagnosis. Although childhood-onset disease is well documented, buy cialis with prescription it is far less common.
Owing to its rarity, the natural history of childhood-onset HCM is not well characterized.12â14 In a clinical research article entitled âClinical characteristics and outcomes in childhood-onset hypertrophic cardiomyopathyâ, Nicholas Marston from the Harvard Medical School in Boston, MA, USA, and colleagues aimed to describe the characteristics and outcomes of childhood-onset HCM.15 They performed an observational cohort study of >7500 HCM patients. HCM patients were stratified by age at diagnosis [<1 year (infancy), 1â18 years (childhood), >18 years (adulthood)] and assessed for composite endpoints including HF, life-threatening ventricular arrhythmias, AF, and an overall composite that also included stroke and death. Stratifying by age of diagnosis, 2.4% of patients were diagnosed in infancy, 14.7% buy cialis with prescription in childhood, and 2.9% in adulthood. Childhood-onset HCM patients had an â¼2%/year event rate for the overall composite endpoint, with ventricular arrhythmias representing the most common event in the first decade following the baseline visit, and HF and AF more common by the end of the second decade. Sarcomeric HCM was more common in childhood-onset HCM (63%) and carried a worse prognosis than non-sarcomeric disease, including a >2-fold increased risk of HF and 67% increased risk of the overall composite outcome buy cialis with prescription.
When compared with adult-onset HCM, those with childhood-onset disease were 36% more likely to develop life-threatening ventricular arrhythmias and twice as likely to require transplant or a ventricular assist device.The authors conclude that patients with childhood-onset HCM are more likely to have sarcomeric disease, carry a higher risk of life-threatening ventricular arrythmias, and have greater need for advanced HF therapies. The manuscript is accompanied by an Editorial by Juan Pablo buy cialis with prescription Kaski from the University College London (UCL) Institute of Cardiovascular Science in London, UK.16 Kaski concludes that the field of HCM is now entering the era of personalized medicine, with the advent of gene therapy programmes and a focus on treatments targeting the underlying pathophysiology. Pre-clinical data suggesting that small molecule myosin inhibitors may attenuate or even prevent disease expression provide cause for optimism, and nowhere more so than for childhood-onset HCM. An international collaborative approach involving basic, translational, and clinical science is now needed to characterize disease expression and progression and develop novel therapies for childhood HCM.Dilated buy cialis with prescription cardiomyopathy (DCM) is a heart muscle disease characterized by LV dilatation and systolic dysfunction in the absence of abnormal loading conditions or coronary artery disease. It is a major cause of systolic HF, the leading indication for heart transplantation, and therefore a major public health problem due to the important cardiovascular morbidity and mortality.17,18 Understanding of the genetic basis of DCM has improved in recent years, with a role for both rare and common variants resulting in a complex genetic architecture of the disease.
In a translational research article entitled âGenome-wide association analysis in dilated cardiomyopathy reveals two new players in systolic heart failure on chromosomes 3p25.1 and 22q11.23â, Sophie Garnier from the Sorbonne Université in Paris, France, and colleagues conducted the largest genome-wide association study performed buy cialis with prescription so far in DCM, with >2500 cases and >4000 controls in the discovery population.19 They identified and replicated two new DCM-associated loci, on chromosome 3p25.1 and chromosome 22q11.23, while confirming two previously identified DCM loci on chromosomes 10 and 1, BAG3 and HSPB7. A PGS constructed from the number of risk alleles at these four DCM loci revealed a 27% increased risk of DCM for individuals with eight risk alleles compared with individuals with five risk alleles (median of the referral population). In silico annotation and functional 4C-sequencing analysis on induced pluripotent stem cell (iPSC)-derived cardiomyocytes identified SLC6A6 as the most likely DCM gene at the 3p25.1 locus. This gene encodes a taurine transporter whose involvement in myocardial dysfunction and DCM is supported by numerous observations in buy cialis with prescription humans and animals. At the 22q11.23 locus, in silico and data mining annotations, and to a lesser extent functional analysis, strongly suggested SMARCB1 as the candidate culprit gene.Garnier et al.
Conclude that their study provides a better understanding of the genetic architecture of DCM and buy cialis with prescription sheds light on novel biological pathways underlying HF. The manuscript is accompanied by an Editorial by Elizabeth McNally from the Northwestern University Feinberg School of Medicine in Chicago, USA, and colleagues.20 The authors conclude that methods to integrate common and rare genetic information will continue to evolve and provide insight on disease progression, potentially providing biomarkers and clues for useful therapeutic pathways to guide drug development. At present, buy cialis with prescription rare cardiomyopathy variants have clinical utility in predicting risk, especially arrhythmic risk. PGS analyses for HF or DCM progression are expected to come to clinical use, especially with the addition of broader GWAS-derived data. Combining genetic risk data with clinical and social determinants should help identify those at greatest risk, offering the opportunity for risk reduction.In a buy cialis with prescription Special Article entitled âInfluenza vaccination.
A âshotâ at INVESTing in cardiovascular healthâ, Scott Solomon from the Brigham and Womenâs Hospital, Harvard Medical School in Boston, MA, USA, and colleagues note that the link between viral respiratory and non-pulmonary organ-specific injury has become increasingly appreciated during the current erectile dysfunction disease 2019 (erectile dysfunction treatment) cialis.21 Even prior to the cialis, however, the association between acute with influenza and elevated cardiovascular risk was evident. The recently published results of the NHLBI-funded INVESTED trial, a 5200-patient comparative effectiveness buy cialis with prescription study of high-dose vs. Standard-dose influenza treatment to reduce cardiopulmonary events and mortality in a high-risk cardiovascular population, found no difference between strategies. However, the broader implications of influenza treatment as a strategy to reduce morbidity in high-risk patients remains extremely important, with randomized control trial and observational data supporting vaccination in high-risk patients with cardiovascular disease. Given a buy cialis with prescription favourable riskâbenefit profile and widespread availability at generally low cost, the authors contend that influenza vaccination should remain a centrepiece of cardiovascular risk mitigation and describe the broader context of underutilization of this strategy.
Few therapeutics in medicine offer seasonal efficacy from a single administration with generally mild, transient side effects and exceedingly low rates of serious adverse effects. control measures buy cialis with prescription such as physical distancing, hand washing, and the use of masks during the erectile dysfunction treatment cialis have already been associated with substantially curtailed incidence of influenza outbreaks across the globe. Appending annual influenza vaccination to these measures represents an important public health and moral imperative.The issue is complemented by two Discussion Forum articles. In a contribution entitled âManagement of acute buy cialis with prescription coronary syndromes in patients presenting without persistent ST-segment elevation and coexistent atrial fibrillationâ, Paolo Verdecchia from the Hospital S. Maria della Misericordia in Perugia, Italy, and colleagues comment on the recently published contribution â2020 ESC Guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation.

Smoothies, Lattes, Popcorn, and More in Pictures See SlideshowLatest Cancer News By Steven ReinbergHealthDay ReporterTHURSDAY, Aug. 27, 2020 (HealthDay News)Cancer patients who need radiation therapy shouldn't let fear of erectile dysfunction treatment delay their treatment, one hospital study suggests.Over six days in May, during the height of the cialis in New Jersey, surfaces in the radiation oncology department at Robert Wood Johnson University Hospital in New Brunswick, N.J., were tested for erectile dysfunction treatment before cleaning.Of 128 samples taken in patient and staff areas and from equipment, including objects used by a patient with erectile dysfunction treatment, not one was positive cialis erection for erectile dysfunction, the cialis that causes erectile dysfunction treatment, the study found.Patients can be reassured that surface contamination is minimal and necessary cancer treatment can go forward safely, said lead researcher Dr.
Bruce Haffty, chairman of radiation oncology at Rutgers Cancer Institute in New Brunswick."Cancer care should and must continue in a erectile dysfunction treatment cialis, and it can be delivered safely and effectively with minimal risk of acquiring a erectile dysfunction treatment from the radiation oncology environment, provided routine measures like mask-wearing, hand-washing, distancing and screening are in place and adhered to," Haffty said.The study does have some limitations. Because of cialis erection the nature of environmental sampling, 100% of a surface could not be swabbed for analysis. And no air samples were taken. But Haffty cialis erection said that because no cialis was found on surfaces, it's doubtful that any cialis was present in the air."An important thing is that we did this testing before cleaning crews came in at the end of the day when there had been all kinds of traffic with patients and staff moving back and forth," he said.Patients and staff routinely wore masks, maintained social distance and washed their hands often, which is probably why no cialis was found, Haffty said.Patients also were screened on arrival with temperature checks and questioned about cialis symptoms, he added.Dr.
Anthony D'Amico cialis erection is chief of radiation oncology at Brigham and Women's Hospital in Boston. He said, "This study corroborates what we have found."Overall, his hospital's rate is 2%, while that in the community next to the hospital is 9%, D'Amico said. But where there are people with lots of underlying conditions and less cialis erection access to health care, the rate is 33%, he said."Hospitals seem to be safer right now than public settings -- protocols that people are using are working," D'Amico said.The takeaway. Patients need not put off treatment out of concern that they could be infected in the hospital."We have told patients not to delay radiation because of erectile dysfunction treatment, because cancer can be more life-threatening than erectile dysfunction treatment," he said.D'Amico's hospital treats patients diagnosed with erectile dysfunction treatment who need radiation before other patients arrive in the morning.
The department is cleaned after cialis erection they leave and at the end of the day after all other patients have gone, he said.Patients with erectile dysfunction treatment symptoms must test negative before undergoing screening tests like mammography and colonoscopy, D'Amico added.In the waiting room, patients and staff wear masks and maintain distancing. Patients' temperatures are taken and they are asked about any symptoms, he said."Patients should feel safe that the person sitting next to them in a waiting room has been properly screened," D'Amico said.The findings were published online Aug. 27 in JAMA Oncology.Copyright © 2020 cialis erection HealthDay.

27, 2020, onlineLatest Heart cialis erection News THURSDAY, Aug. 27, 2020 (HealthDay News)Heart attack survivors are more likely to lose weight if their spouses join them in shedding excess pounds, new research shows."Lifestyle improvement after a heart attack is a crucial part of preventing repeat events," said study author Lotte Verweij, a registered nurse and Ph.D. Student at Amsterdam University of Applied Sciences, in cialis erection the Netherlands. "Our study shows that when spouses join the effort to change habits, patients have a better chance of becoming healthier -- particularly when it comes to losing weight."The study included 411 heart attack survivors who, along with receiving usual care, were referred to up cialis erection to three lifestyle change programs for weight loss, increased physical activity and quitting smoking.The patients' partners could attend the programs for free and were encouraged by nurses to take part.
Nearly half (48%) of the patients' partners participated, which was defined as attending at least once.Compared to those without a partner, patients with a participating partner were more than twice as likely to improve in at least one of the three areas (weight loss, exercise, smoking cessation) within a year, the findings showed.When the influence of partners was analyzed in the three areas separately, patients with a participating partner were more successful in shedding weight compared to patients without a partner, according to the study presented Thursday at a virtual meeting of the European Society of Cardiology. Such research is considered preliminary until published in a peer-reviewed journal.But partner participation did not improve heart attack survivors' likelihood of quitting smoking or becoming more physically active, according to the report."Patients with partners who joined the weight-loss program lost more weight compared to patients with a partner who did cialis erection not join the program," Verweij said in a society news release."Couples often have comparable lifestyles, and changing habits is difficult when only one person is making the effort.

Good news is most symptoms can be avoided by taking a few simple steps," pediatric ophthalmologist Dr. Stephen Lipsky, a clinical spokesperson for the academy, said in an academy news release.Here he offers these remote-learning recommendations to protect your child's vision:Set a timer to remind your cialis erection child to take a break every 20 minutes. Alternate reading on an e-book with a real book. Encourage children to look up and out the window every two chapters or to shut their eyes cialis erection for 20 seconds.Mark books with paperclips every few chapters.
When they reach a paper clip, it will remind them look up. On an e-book, use the bookmark function for the same effect.Make sure children use laptops at arm's length (about 18 cialis erection to 24 inches) from where they're sitting. Ideally, they should have a monitor positioned at eye level, directly cialis erection in front of the body. Tablets should also be held at arm's length.To reduce glare, position the light source behind the child's back, not behind the screen.
Adjust the brightness and contrast cialis erection on the screen so that it feels comfortable for children. Don't use a device outside or in brightly lit areas. The glare on the screen can cause eye strain.Children shouldn't use a device in a cialis erection dark room. As the pupil expands to adjust to the darkness, the brightness of the screen can aggravate after-images and cause discomfort.Children should stop using devices 30 to 60 minutes before bedtime.
Blue light cialis erection may disrupt sleep. If teens don't want to do this, have them switch to night mode or a similar mode to reduce blue light exposure.When study time is over, make sure children spend time outdoors. Several studies cialis erection suggest that spending time outdoors, especially in early childhood, can slow the progression of nearsightedness.-- Robert PreidtCopyright © 2020 HealthDay.

Bruce Haffty, chairman of radiation oncology at Rutgers Cancer Institute in New Brunswick."Cancer care should and must continue in a erectile dysfunction treatment cialis, and it can be delivered safely and effectively with minimal risk of acquiring a erectile dysfunction treatment from the radiation oncology environment, provided routine measures like mask-wearing, hand-washing, distancing and screening are in place and adhered to," Haffty said.The study does have some limitations. Because of the nature of environmental sampling, 100% of a surface could not be swabbed for analysis buy cialis with prescription. And no air samples were taken. But Haffty said that because no cialis was found on surfaces, it's doubtful that any cialis was present in the air."An important thing is that we did this testing before cleaning crews came in at the end of the day when buy cialis with prescription there had been all kinds of traffic with patients and staff moving back and forth," he said.Patients and staff routinely wore masks, maintained social distance and washed their hands often, which is probably why no cialis was found, Haffty said.Patients also were screened on arrival with temperature checks and questioned about cialis symptoms, he added.Dr.
Anthony D'Amico buy cialis with prescription is chief of radiation oncology at Brigham and Women's Hospital in Boston. He said, "This study corroborates what we have found."Overall, his hospital's rate is 2%, while that in the community next to the hospital is 9%, D'Amico said. But where there are people with lots of underlying conditions and less access to health care, the rate is 33%, he said."Hospitals seem to buy cialis with prescription be safer right now than public settings -- protocols that people are using are working," D'Amico said.The takeaway. Patients need not put off treatment out of concern that they could be infected in the hospital."We have told patients not to delay radiation because of erectile dysfunction treatment, because cancer can be more life-threatening than erectile dysfunction treatment," he said.D'Amico's hospital treats patients diagnosed with erectile dysfunction treatment who need radiation before other patients arrive in the morning.
The department buy cialis with prescription is cleaned after they leave and at the end of the day after all other patients have gone, he said.Patients with erectile dysfunction treatment symptoms must test negative before undergoing screening tests like mammography and colonoscopy, D'Amico added.In the waiting room, patients and staff wear masks and maintain distancing. Patients' temperatures are taken and they are asked about any symptoms, he said."Patients should feel safe that the person sitting next to them in a waiting room has been properly screened," D'Amico said.The findings were published online Aug. 27 in buy cialis with prescription JAMA Oncology.Copyright © 2020 HealthDay.
