how to buy viagra been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1–13 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 patients who have a DSD.11 14 Several projects have now worked to natural viagra resolve this variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 ‘A systematic elucidation of differences of sex development’ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15–17 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 highlighted how cultural and financial aspects and the availability of natural viagra 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 natural viagra 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 of this kind of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have natural viagra 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 natural viagra 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 the prenatal to the natural viagra 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 is challenging and would benefit from international collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre natural viagra 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 natural viagra 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 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 terms (eg, DSD, genetic, review, diagnosis, natural viagra diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care).

Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports natural viagra were excluded, as 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 was discussed by the writing committee and, natural viagra 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 natural viagra and incorporating their 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 at the request of the parents.Another way DSD can be diagnosed before birth is when invasive prenatal genetic testing carried out for natural viagra 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 natural viagra 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 natural viagra on legal restrictions and/or ethical considerations, the X and 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 11–13 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 natural viagra 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 natural viagra ultrasound findings and the limitations of this technique.

The procedure(s) that can be followed, including the risks associated with an amniocentesis. And the type of information genetic testing can and cannot provide natural viagra. 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 child’s 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 prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available natural viagra 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 apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered natural viagra 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 child’s genitalia will look like and uncertainty about the diagnosis, treatment and prognosis cannot be avoided natural viagra 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 natural viagra 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, ‘your baby’) as long as sex assignment is pending.An algorithm for diagnostic evaluation of a suspected DSD in natural viagra 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 natural viagra 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 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 parents’ genetics.29–31 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 natural viagra limit, 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 child’s 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 48 hours 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 35–38 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 Wilms’ 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 coauthors’ 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.41–44 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.15–17 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 48–50 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 patient’s 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.15–17 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 diseases—Project 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 5 year 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 3–5% of cases.8–10 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.

€œendomet*”,“uter*”, “womb”, “cancer(s)”, “neoplasm(s)”, “endometrium tumour”, “carcinoma”, “adenosarcoma”, “clear cell carcinoma”, “carcinosarcoma”, “SNP”, “single nucleotide polymorphism”, “GWAS”, and “genome-wide association study/ies”. 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.

Chronbach’s α score was calculated between reviewers and indicated high consistency at 0.92. Case–control, 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% CI), 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 <5×10-8, 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 <1×10-5, 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 2∑βipI and SE, σ, equal to √2∑βi2pI(1−pi), 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(Z0.01σ), 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 literature21–25Study 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).21–25 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 28–30 Moreover, a recent article authored by O’Mara 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% CI 1.32 to 2.04. P=9.6×10-6) compared with the endometrioid arm (OR 1.25, 95% CI 1.14 to 1.38. P=4.7×10-6).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. O’Mara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86×10-5).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% CI 1.11 to 1.21. P=4.83×10-11), the A allele of rs9600103 (OR 1.23, 95% CI 1.16 to 1.30. P=3.76×10-12) and C allele of rs7981863 (OR 1.16, 95% CI 1.12 to 1.20.

P=2.70×10-17) 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 O’Mara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5×10–8.35To 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 criteria—one 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 13 000 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 42–44DiscussionThis 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 O’Mara et al, which utilised 12 096 cases and 108 979 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 200 000 individuals with more than half being cases, and resulted in identification of ~170 SNPs 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 150 000 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% CI, 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 O’Mara 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, O’Mara 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 protein–protein 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 Bokhman’s 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..

Ketoacidosis and fluidsThe debate around fluid resuscitation and maintenance in DKA has been smouldering for years, the recent, whats a viagra large PECARN FLUID trial providing some guidance, but, you could check here not drawing a line under all the issuesIn the light of the study, revisiting the arguments is useful and a group of three papers re-open the discussion. The catalyst on this occasion has been the publication of new British Society of Paediatric Endocrinology (BSPED) guidance, recommendations which leave ultimate decision making to the individual clinician but in broad terms suggest an initial resuscitation bolus (of 10 mL/kg) to all children. Our first correspondent, John Lillie on behalf of the South Thames Retrieval Service whose policy has been restrictive whats a viagra since 2008 after three deaths from DKA associated cerebral oedema argues that degree of dehydration (an agreed moot point by all parties) is all too easily overestimated particularly when capillary refill time (prolonged by hypocapnoea inherent to ketosis) is used to make the assessment. Neil Wright on behalf of BPSED argues that once initial resuscitation is completed there is little difference philosophically between the two approachesThe physiology, science and moot points are weighed up in Robert Tasker’s editorial in which one bystander in recent debate, the rate of insulin infusion is also revisited, a lower exposure causing less rapid shifts in osmotic pressure and (theoretically) less risk of cerebral oedema. Here we come full circle in that the number of children developing this complication is so low that even a trial as large as FLUID is potentially underpowered.

See pages 1019, 1020 and 917Perinatal encephalopathyThe dangers of over-diagnosis of a vague entity are highlighted in whats a viagra Mustayev’s systematic review. The term perinatal encephalopathy (PE) (sometimes also called the ‘syndrome of intracranial hypertension’) was coined by a Russian paediatrician Iurii Iakunin in the 1970s referring to a range of signs and symptoms thought to be attributable to a perinatal insult, mediated by a rise in intracranial pressure. The notion was admirable, but the group of disorders whats a viagra inevitably heterogenous. As the term became more widely used in Eastern European countries, it was sometimes applied to infants and children with transient signs and no discernable pathology. The nomenclature was (paradoxically) reinforced by the lack of a unifying diagnostic test.

The label being at the discretion of the paediatrician or paediatric neuropathologist, to which many of these whats a viagra infants were referred. Diagnoses result in treatments and wide range of agents had been used on occasions. Anticonvulsants, mineral and metabolic supplements, diuretics, cattle-derived neuropeptides, vasoactive agents, psychostimulants, and physical therapies. The issue of the Perinatal Encephalopathy Syndrome has long whats a viagra been on the radar of the WHO, and was the subject of a meeting in St Petersburg in 2007, at which many positive signs of reform were seen. This review shows further change, but some areas of continuing concern related to the diagnosis which still appears to be applied in some areas.

These potential harms whats a viagra are both direct and indirect and include the failure to diagnose other disorders. Unnecessary follow-up appointments and diagnostic procedures. The development of the vulnerable child syndrome. And even deferral of vaccinations whats a viagra. See page 921After sudden infant deathSUDI is a rare event and a second death in a subsequent child extremely unusual, but to date there has been little data to quantify the recurrence risk and counsel parents.

Garstang’s analysis of the Care of the Next Infant database from 2000 to 2015 provides some answers. Over this period, 6608 live-born infants whats a viagra were registered. 171 were first-born infants to mothers whose male partners had previously had an unexplained infant death. 29 unexpected infant deaths whats a viagra following the index death occurred in 26 families, 23 with 2 deaths and 3 with three deaths. The second SUDI rate was estimated as 3.93 per 1000 live births and the third as 115 per 1000 live births.

The findings should not, though, engender complacency as there have in the past been convictions for homicide. The risk of repeat SUDI in a family is whats a viagra still 10 times that of the general population, a reflection of inherent genetic risks as well as environmental factors such as maternal smoking and unsafe sleeping. CONI cannot address intrinsic risk factors, but these are very vulnerable families who need comprehensive care and support packages to help them understand safe sleeping, address mental health problems and enhance their parenting capacity. See page 945Emergency steroids and whats a viagra asthma prophylaxisIn a neat and salutary reminder of the reason some children reach the stage of requiring rescue oral corticosteroids (OCS) at routine clinic appointments, Willson reviews experience from a quarternary respiratory department with respect to adherence prescribed prophylaxis. In the series 25 children received 32 courses of OCS.

For those episodes with full data, uptake of prescriptions for inhaled corticosteroid prophylaxis, the median uptake over the previous 6 months was only 33% and in only 29% episodes was uptake ≥75% of that prescribed So, rather than just prescribe the emergency course and ascribe it to bad luck or bad asthma… maybe check on adherence. This and related themes whats a viagra are explored in Ian Sinha’s Viewpoint exploration of the national respiratory audit database. See pages 993 and 910Monitoring inflammatory bowel diseaseEqually pragmatic is the issue with calprotectin stability described by Haisma. Stool calprotectin is pivotal in the diagnosis, monitoring of and to treatment modifications in IBD. Often a sample will be taken in the home and dropped off at the lab or sent by post having spent time at room temperature in the interim rather whats a viagra than the recommended 4 C.

The fall how much is viagra at cvs in levels is so great (35% and 46% in extraction buffer) that disease activity will inevitably be underestimated and treatment not increased appropriately. So, before reducing immune modulating treatment immediately, check how the sample travelled before analysis and, whats a viagra if in any doubt, recheck making any changes. See page 996Two letters in the journal focus on the volume of intravenous fluid to be used during resuscitation and early management of paediatric patients presenting with diabetic ketoacidosis (DKA).1 2 The correspondence encapsulates an important debate about intravenous fluids and risk of morbidities, such as cerebral oedema, and provides us with the range in contemporary opinions in the UK.Lillie et al1 use their insights from the South Thames Retrieval service (STRS) and its 20 referring district general hospitals to highlight a concern about the new British Society for Paediatric Endocrinology and Diabetes (BSPED) guideline3 and integrated care pathway4 for the management of DKA. The authors have a network of emergency practice, and they imply that the new emphasis by the BSPED on permissive rather than restrictive (ie, reduced volume rules) intravenous fluids will be disruptive to the measures that they have taken since dealing with three cerebral oedema deaths in their region. Wright and Thomas2 have responded on behalf of the whats a viagra BSPED DKA interest group.

They emphasise the importance of adequate intravenous fluid resuscitation in limiting morbidity. They also provide an instructive table2 showing fluid resuscitation and rehydration volumes used in a number of protocols, including that of STRS and the new BSPED approach. The main differences come down to the estimate of fluid deficit, the use of an intravenous fluid bolus at presentation and the calculation of maintenance fluid requirements.The STRS approach assumes a 10% fluid deficit in all patients with DKA at presentation, versus the new BSPED guideline’s use of three levels in estimated fluid deficit based on severity of acidosis (ie, whats a viagra pH >7.2, 5%. PH 7.1 to 7.2, 7%. And pH whats a viagra <7.1, 10%).

In the STRS approach, an intravenous fluid bolus of 10 mL/kg normal saline (NS) is reserved for patients in shock. In contrast, the new BSPED guideline recommends that all patients with DKA receive an intravenous bolus of 10 mL/kg NS, with an extra 10 mL/kg NS (20 mL/kg in total) for those in shock. Last, in whats a viagra the STRS protocol, the 10% fluid deficit is repaired over 48 hours by adding the volume to restrictive or so-called reduced volume rules for maintenance intravenous requirements and for body weight (ie, up to 10 kg, 2 mL/kg/hour. 10–14 kg, 1 mL/kg/hour and >40 kg, fixed volume 40 mL/hr). The new BSPED guideline also recommends replacing the presumed fluid deficit over 48 hours, but this hourly volume is added to whats a viagra standard (and higher than reduced volume rules) maintenance intravenous fluids.4 5Now, add to this mixture of opinions, the UK National Institute for Health and Care Excellence (NICE) latest updated pathway for DKA in children and young people.6 Like the new BSPED guideline, NICE also estimates fluid deficit based on severity of acidosis.

However, severity of fluid deficit is dichotomised to 5% or 10% based on whether pH is above or below 7.1, respectively. Like the STRS approach, there is no routine use of an intravenous NS fluid bolus in severe DKA. Last, like the STRS approach the estimated fluid deficit is repaired over 48 hours by adding the hourly volume to whats a viagra maintenance requirement calculated using reduced volume rules.How can there be such variance in opinion and recommendations and what should we do?. To be fair, the new BSPED guideline3 was only ever ‘… an interim recommendation pending the publication of the future NICE review.’ But, more importantly, the BSPED website acknowledges that the onus for decision-making remains with the clinician. A similar stance on responsibility of guideline users is also taken by NICE.The new information that seems to have influenced the BSPED and the NICE updates on DKA is the Pediatric Emergency Care Applied Research Network (PECARN) clinical trial of fluid infusion rates for paediatric DKA (FLUID trial).7 It is worth re-reading the paper and its protocol and supplementary appendix, in particular have a look at Figure S1 on compliance to assigned fluid rate.

The bottom line of the FLUID trial is that neither the rate of administration (fast vs slow repair) nor the sodium chloride whats a viagra content (NS vs 0.45% saline) of intravenous fluids significantly influenced neurological outcomes. Wright and Thomas2 show in their table that the difference between fast and slow repair in the trial was complex and not only included a difference in timing of fluid-deficit repair (ie, fast with 50% repair in first 12 hours followed by 50% repair in next 24 hours vs slow repair evenly distributed over 48 hours). It also involved differences in presumed fluid deficit (10% vs 5%) and whats a viagra use of intravenous NS boluses (20 mL/kg vs 10 mL/kg). Close review of the compliance to assigned fluid rate in the FLUID trial (see Supplemental Figure S17) shows that actual fluid received by patients in the fast and slow repair groups are similar to those suggested by the BSPED and STRS/NICE, respectively. If there is no difference in neurological outcome, does the difference in fluid strategy really matter, as each of our correspondents argue?.

To attempt to answer this whats a viagra question we have to look at two key details of the FLUID trial. The first is that of the 1389 patients undergoing randomisation, 1263 (91%) had Glasgow Coma Scale (GCS) score 15, 99 (7%) had GCS score 14 and 28 (2%) had GCS score <14. In essence, the test of fast versus slow fluid strategy is strongly influenced by patients with DKA who are fully awake at presentation. Both of our correspondents1 2 acknowledge that patients whats a viagra with altered mental state raise concern, although their approaches differ—on this matter we have no answer from the FLUID trial. The other detail to consider is that the uniformly used standard insulin infusion rate (0.1 U/kg/hour) differs from the dosing range (0.05 to 0.1 U/kg/hour) used in UK practice.3 4 6 One theoretical aim of low-dose insulin (0.05 U/kg/hour)8 9 is to avoid too rapid decrease in serum glucose concentration (ie, >5.5 mmol/L/hour), with consequent too rapid change in serum osmolarity, which may increase the risk of cerebral oedema.10 11 Does this idea mean that the low-dose insulin strategy enables better tolerance of fast-fluid repair rate, with low risk of morbidity?.

Impossible whats a viagra to answer. As we see from the FLUID trial, such a proposition—with an outcome of brain injury in less than 1% of DKA episodes—is likely untestable in a future sufficiently powered clinical trial.Taking all the above together, there is clearly a need to realign the variance in DKA fluid management reflected in the STRS,1 BSPED2–4 and NICE6 approaches. Even though we have gold standard clinical information from the PECARN DKA FLUID trial,7 the relevance of that information to all paediatric patients presenting with DKA needs careful consideration. Which means whats a viagra that clinicians still need to exercise judgement in individual situations. Finally, the letter by Lillie et al1 also reminds us of the value of systems of care.

Their hub-and-spoke network for emergency DKA care is not just about adopting latest recommendations but is also tasked with bringing about any necessary knowledge-to-action change (see the table and figure 2 as responses to three cerebral oedema DKA deaths),1 a process called implementation science.12.

Ketoacidosis and natural viagra fluidsThe debate around fluid resuscitation and maintenance in DKA has been smouldering for years, the recent, large PECARN FLUID trial providing some guidance, but, not drawing a line under all the issuesIn the light of the study, revisiting the arguments is useful and a group of three papers re-open the discussion.

The issue of the Perinatal Encephalopathy Syndrome has long been on the radar of the WHO, and was the subject of a meeting in St Petersburg in 2007, at which many positive signs of reform were natural viagra seen. This review shows further change, but some areas of continuing concern related to the diagnosis which still appears to be applied in some areas. These potential harms are both direct and indirect and include the failure to diagnose other natural viagra disorders.

Unnecessary follow-up appointments and diagnostic procedures. The development of the vulnerable child syndrome. And even deferral of natural viagra vaccinations. See page 921After sudden infant deathSUDI is a rare event and a second death in a subsequent child extremely unusual, but to date there has been little data to quantify the recurrence risk and counsel parents.

Garstang’s analysis of the Care of the Next Infant database from 2000 to 2015 provides some answers. Over this period, 6608 live-born natural viagra infants were registered. 171 were first-born infants to mothers whose male partners had previously had an unexplained infant death. 29 unexpected infant deaths following natural viagra the index death occurred in 26 families, 23 with 2 deaths and 3 with three deaths.

The second SUDI rate was estimated as 3.93 per 1000 live births and the third as 115 per 1000 live births. The findings should not, though, engender complacency as there have in the past been convictions for homicide. The risk of repeat SUDI in a family is still 10 times that of the general natural viagra population, a reflection of inherent genetic risks as well as environmental factors such as maternal smoking and unsafe sleeping. CONI cannot address intrinsic risk factors, but these are very vulnerable families who need comprehensive care and support packages to help them understand safe sleeping, address mental health problems and enhance their parenting capacity.

See page 945Emergency steroids and asthma prophylaxisIn a neat and salutary reminder natural viagra of the reason some children reach the stage of requiring rescue oral corticosteroids (OCS) at routine clinic appointments, Willson reviews experience from a quarternary respiratory department with respect to adherence prescribed prophylaxis. In the series 25 children received 32 courses of OCS. For those episodes with full data, uptake of prescriptions for inhaled corticosteroid prophylaxis, the median uptake over the previous 6 months was only 33% and in only 29% episodes was uptake ≥75% of that prescribed So, rather than just prescribe the emergency course and ascribe it to bad luck or bad asthma… maybe check on adherence. This and related themes are explored in Ian Sinha’s Viewpoint exploration natural viagra of the national respiratory audit database.

See pages 993 and 910Monitoring inflammatory bowel diseaseEqually pragmatic is the issue with calprotectin stability described by Haisma. Stool calprotectin is pivotal in the diagnosis, monitoring of and to treatment modifications in IBD. Often a sample will be taken in the home and dropped off at the lab or sent by post having spent time at room temperature in the natural viagra interim rather than the recommended 4 C. The fall in levels is so great (35% and 46% in extraction buffer) that disease activity will inevitably be underestimated and treatment not increased appropriately.

So, before reducing immune modulating treatment immediately, check how the sample travelled before analysis and, if in any doubt, recheck making natural viagra any changes. See page 996Two letters in the journal focus on the volume of intravenous fluid to be used during resuscitation and early management of paediatric patients presenting with diabetic ketoacidosis (DKA).1 2 The correspondence encapsulates an important debate about intravenous fluids and risk of morbidities, such as cerebral oedema, and provides us with the range in contemporary opinions in the UK.Lillie et al1 use their insights from the South Thames Retrieval service (STRS) and its 20 referring district general hospitals to highlight a concern about the new British Society for Paediatric Endocrinology and Diabetes (BSPED) guideline3 and integrated care pathway4 for the management of DKA. The authors have a network of emergency practice, and they imply that the new emphasis by the BSPED on permissive rather than restrictive (ie, reduced volume rules) intravenous fluids will be disruptive to the measures that they have taken since dealing with three cerebral oedema deaths in their region. Wright and Thomas2 have responded on natural viagra behalf of the BSPED DKA interest group.

They emphasise the importance of adequate intravenous fluid resuscitation in limiting morbidity. They also provide an instructive table2 showing fluid resuscitation and rehydration volumes used in a number of protocols, including that of STRS and the new BSPED approach. The main differences come down to the estimate of fluid deficit, the use of an intravenous fluid bolus at presentation and the calculation of maintenance fluid requirements.The STRS approach assumes a 10% fluid deficit in all patients with DKA at presentation, versus the new BSPED guideline’s use of three levels in natural viagra estimated fluid deficit based on severity of acidosis (ie, pH >7.2, 5%. PH 7.1 to 7.2, 7%.

And pH <7.1, natural viagra 10%). In the STRS approach, an intravenous fluid bolus of 10 mL/kg normal saline (NS) is reserved for patients in shock. In contrast, the new BSPED guideline recommends that all patients with DKA receive an intravenous bolus of 10 mL/kg NS, with an extra 10 mL/kg NS (20 mL/kg in total) for those in shock. Last, in the STRS protocol, the 10% fluid deficit is repaired over 48 hours by adding the volume to restrictive or so-called reduced volume rules natural viagra for maintenance intravenous requirements and for body weight (ie, up to 10 kg, 2 mL/kg/hour.

10–14 kg, 1 mL/kg/hour and >40 kg, fixed volume 40 mL/hr). The new BSPED guideline also recommends replacing the presumed fluid deficit over 48 hours, but this hourly volume is added to standard (and higher than reduced volume rules) maintenance intravenous fluids.4 5Now, add to this mixture of opinions, the UK National Institute for Health and Care Excellence (NICE) latest updated pathway for DKA in children natural viagra and young people.6 Like the new BSPED guideline, NICE also estimates fluid deficit based on severity of acidosis. However, severity of fluid deficit is dichotomised to 5% or 10% based on whether pH is above or below 7.1, respectively. Like the STRS approach, there is no routine use of an intravenous NS fluid bolus in severe DKA.

Last, like the STRS approach the estimated fluid deficit is repaired over 48 hours by adding the hourly volume to maintenance requirement calculated using natural viagra reduced volume rules.How can there be such variance in opinion and recommendations and what should we do?. To be fair, the new BSPED guideline3 was only ever ‘… an interim recommendation pending the publication of the future NICE review.’ But, more importantly, the BSPED website acknowledges that the onus for decision-making remains with the clinician. A similar stance on responsibility of guideline users is also taken by NICE.The new information that seems to have influenced the BSPED and the NICE updates on DKA is the Pediatric Emergency Care Applied Research Network (PECARN) clinical trial of fluid infusion rates for paediatric DKA (FLUID trial).7 It is worth re-reading the paper and its protocol and supplementary appendix, in particular have a look at Figure S1 on compliance to assigned fluid rate. The bottom line of the FLUID trial is that neither the rate of administration (fast vs slow natural viagra repair) nor the sodium chloride content (NS vs 0.45% saline) of intravenous fluids significantly influenced neurological outcomes.

Wright and Thomas2 show in their table that the difference between fast and slow repair in the trial was complex and not only included a difference in timing of fluid-deficit repair (ie, fast with 50% repair in first 12 hours followed by 50% repair in next 24 hours vs slow repair evenly distributed over 48 hours). It also involved differences in presumed fluid deficit (10% vs 5%) and use of intravenous NS boluses (20 mL/kg natural viagra vs 10 mL/kg). Close review of the compliance to assigned fluid rate in the FLUID trial (see Supplemental Figure S17) shows that actual fluid received by patients in the fast and slow repair groups are similar to those suggested by the BSPED and STRS/NICE, respectively. If there is no difference in neurological outcome, does the difference in fluid strategy really matter, as each of our correspondents argue?.

To attempt to answer this question we have to look at natural viagra two key details of the FLUID trial. The first is that of the 1389 patients undergoing randomisation, 1263 (91%) had Glasgow Coma Scale (GCS) score 15, 99 (7%) had GCS score 14 and 28 (2%) had GCS score <14. In essence, the test of fast versus slow fluid strategy is strongly influenced by patients with DKA who are fully awake at presentation. Both of our correspondents1 2 natural viagra acknowledge that patients with altered mental state raise concern, although their approaches differ—on this matter we have no answer from the FLUID trial.

The other detail to consider is that the uniformly used standard insulin infusion rate (0.1 U/kg/hour) differs from the dosing range (0.05 to 0.1 U/kg/hour) used in UK practice.3 4 6 One theoretical aim of low-dose insulin (0.05 U/kg/hour)8 9 is to avoid too rapid decrease in serum glucose concentration (ie, >5.5 mmol/L/hour), with consequent too rapid change in serum osmolarity, which may increase the risk of cerebral oedema.10 11 Does this idea mean that the low-dose insulin strategy enables better tolerance of fast-fluid repair rate, with low risk of morbidity?. Impossible to natural viagra answer. As we see from the FLUID trial, such a proposition—with an outcome of brain injury in less than 1% of DKA episodes—is likely untestable in a future sufficiently powered clinical trial.Taking all the above together, there is clearly a need to realign the variance in DKA fluid management reflected in the STRS,1 BSPED2–4 and NICE6 approaches. Even though we have gold standard clinical information from the PECARN DKA FLUID trial,7 the relevance of that information to all paediatric patients presenting with DKA needs careful consideration.

Which means that clinicians still need to natural viagra exercise judgement in individual situations. Finally, the letter by Lillie et al1 also reminds us of the value of systems of care. Their hub-and-spoke network for emergency DKA care is not just about adopting latest recommendations but is also tasked with bringing about any necessary knowledge-to-action change (see the table and figure 2 as responses to three cerebral oedema DKA deaths),1 a process called implementation science.12.

Viagra dosage for 30 year old

Have you ever woken up with a sore throat viagra dosage for 30 year old and used your phone donde venden viagra to get a virtual visit?. The odds are it’s not available to you, and there is a reason for that. You may be hearing about how virtual care, often described as telehealth or telemedicine, is beneficial during COVID-19 and how health systems are offering virtual access like never before.

There’s a viagra dosage for 30 year old reason for that, too. For the past few weeks I’ve seen Facebook posts daily from former nursing colleagues in metro Detroit, one of the hardest hit areas in the country, as they provide front-line care to patients with COVID-19. It makes me very proud to call these nurses my friends.

As a former emergency department nurse, I recall the feeling of satisfaction knowing that I’ve helped someone on the worst day of their life viagra dosage for 30 year old. One of the best parts of being a nurse is knowing you matter to the only person in health care that truly matters. The patient.

Several years ago I made the difficult decision to no longer perform bedside nursing and become viagra dosage for 30 year old a nurse administrator. The biggest loss from my transition is the feeling that what I do matters to the patient. COVID-19 has forced a lot of us to rethink the role we play in health care and what the real priority should be.

Things that were top priorities three months ago have been rightfully cast aside to either care for patients in a pandemic viagra dosage for 30 year old or prepare for the unknown future of, “When is our turn?. € For me, COVID-19 has reignited the feeling that what I do matters as virtual care has become a powerful tool on the forefront of care during this crisis. It has also shown that many of the powerful rules and regulations that limit virtual care are not needed and should be discarded permanently.

When I became the director of virtual care at our viagra dosage for 30 year old organization in 2015 I knew nothing about telehealth. Sure, I had seen a stroke robot in some Emergency Departments, and I had some friends that told me their insurance company lets them FaceTime a doctor for free (spoiler alert. It’s not FaceTime).

I was tech-savvy from a consumer perspective and a tech novice from viagra dosage for 30 year old an IT perspective. Nevertheless, my team and I spent the next few years learning as we built one of the higher volume virtual care networks in the state of Michigan. We discovered a lot of barriers that keep virtual care from actually making the lives of patients and providers better and we also became experts in working around those barriers.

But, there viagra dosage for 30 year old were two obstacles that we could not overcome. Government regulation and insurance provider willingness to cover virtual visits. These two barriers effectively cripple most legitimate attempts to provide value-added direct-to-consumer virtual care, which I define as using virtual care technologies to provide care outside of our brick-and-mortar facilities, most commonly in the patient home.

The need to social distance, cancel appointments, close provider offices, keep from viagra dosage for 30 year old overloading emergency departments and urgent cares and shelter in place created instant demand for direct-to-consumer virtual care. In all honesty, I’ve always considered direct-to-consumer virtual care to be the flashy, must-have holiday gift of the year that organizations are convinced will be the way of the future. If a health system wants to provide on-demand access to patients for low-complexity acute conditions, they will easily find plenty of vendors that will sell them their app and their doctors and put the health system’s logo on it.

What a health system will struggle with is to find is enough patient demand to cover the high cost viagra dosage for 30 year old. Remember my friends from earlier that told me about the app their insurance gave them?. Nearly all of them followed that up by telling me they’ve never actually used it.

I am fortunate that I work for an organization that understands this and instead focuses on how can we provide care that viagra dosage for 30 year old our patients actually want and need from the doctors they want to see. Ironically, this fiscal year we had a corporate top priority around direct-to-consumer virtual care. We wanted to expand what we thought were some successful pilots and perform 500 direct-to-consumer visits.

This year has been one of the hardest of viagra dosage for 30 year old my leadership career because, frankly, up until a month ago I was about to fail on this top priority. With only four months left, we were only about halfway there. The biggest problem we ran into was that every great idea a physician brought to me was instantly dead in the water because practically no insurance company would pay for it.

There are (prior to COVID-19) a plethora of rules around virtual care billing but the simplest way to summarize it is that most virtual care will only be paid viagra dosage for 30 year old if it happens in a rural location and inside of a health care facility. It is extremely limited what will be paid for in the patient home and most of it is so specific that the average patient isn’t eligible to get any in-home virtual care. Therefore, most good medical uses for direct-to-consumer care would be asking the patient to pay cash or the physician to forgo reimbursement for a visit that would be covered if it happened in office.

Add to that the massive capital and operating expenses it takes to build a virtual care network and you viagra dosage for 30 year old can see why these programs don’t exist. A month ago I was skeptical we’d have a robust direct-to-consumer program any time soon and then COVID-19 hit. When COVID-19 started to spread rapidly in the United States, regulations and reimbursement rules were being stripped daily.

The first change that had major impact is when the Centers for Medicare and Medicaid viagra dosage for 30 year old Services (CMS) announced that they would temporarily begin reimbursing for virtual visits conducted in the patient’s home for COVID-19 and non-COVID related visits. We were already frantically designing a virtual program to handle the wave of COVID-19 screening visits that were overloading our emergency departments and urgent cares. We were having plenty of discussions around reimbursement for this clinic.

Do we attempt to bill insurances knowing they will likely deny, do we do a cash clinic model or do we do this as a community benefit and eat viagra dosage for 30 year old the cost?. The CMS waiver gave us hope that we would be compensated for diverting patients away from reimbursed visits to a virtual visit that is more convenient for the patient and aligns with the concept of social distancing. Realistically we don’t know if we will be paid for any of this.

We are holding all of the bills for at least 90 days while the industry sorts out the viagra dosage for 30 year old rules. I was excited by the reimbursement announcement because I knew we had eliminated one of the biggest direct-to-consumer virtual care barriers. However, I was quickly brought back to reality when I was reminded that HIPAA (Health Insurance Portability and Accountability Act) still existed.

I had this crazy idea that during a pandemic we should make it as easy as possible for viagra dosage for 30 year old people to receive virtual care and that the best way to do that was to meet the patient on the device they are most comfortable with and the application (FaceTime, Facebook, Skype, etc.) that they use every day. The problem is nearly every app the consumer uses on a daily basis is banned by HIPAA because “it’s not secure.” I’m not quite sure what a hacker stands to gain by listening into to my doctor and me talk about how my kids yet again gave me strep throat but apparently the concern is great enough to stifle the entire industry. Sure, not every health check this site out care discussion is as low-key as strep throat and a patient may want to protect certain topics from being discussed over a “non-secure” app but why not let the patient decide through informed consent?.

Regulators could also abandon this all-or-nothing approach viagra dosage for 30 year old and lighten regulations surrounding specific health conditions. The idea that regulations change based on medical situation is not new. For example, in my home state of Michigan, adolescents are essentially considered emancipated if it involves sexual health, mental health or substance abuse.

Never mind that this same information is freely given over the phone by every viagra dosage for 30 year old office around the country daily without issue, but I digress. While my job is to innovate new pathways for care, our lawyer’s job is to protect the organization and he, along with IT security, rightfully shot down my consumer applications idea. A few days later I legitimately screamed out loud in joy when the Department of Health and Human Services announced that it would use discretion on enforcing HIPAA compliance rules and specifically allowed for use of consumer applications.

The elimination of billing restrictions and HIPAA regulations changed what viagra dosage for 30 year old is possible for health care organizations to offer virtually. Unfortunately both changes are listed as temporary and will likely be removed when the pandemic ends. Six days after the HIPAA changes were announced, we launched a centralized virtual clinic for any patient that wanted a direct-to-consumer video visit to be screened by a provider for COVID-19.

It allows patients to call viagra dosage for 30 year old in without a referral and most patients are on-screen within five minutes of clicking the link we text them. They don’t have to download an app, create an account or even be an established patient of our health system. It saw over 900 patients in the first 12 days it was open.

That is viagra dosage for 30 year old 900 real patients that received care from a physician or advanced practice provider without risking personal exposure and without going to an already overwhelmed ED or urgent care. To date, 70 percent of the patients seen by the virtual clinic did not meet CDC testing criteria for COVID-19. I don’t believe we could have reached even half of these patients had the consumer application restrictions been kept.

A program like this almost certainly wouldn’t exist if not for the regulations being lifted and even if it did, it would have taken six to viagra dosage for 30 year old 12 months to navigate barriers and implement in normal times. Sure, the urgency of a pandemic helps but the impact of provider, patients, regulators and payors being on the same page is what fueled this fire. During the virtual clinic’s first two weeks, my team turned its attention to getting over 300 providers across 60+ offices virtual so they could see their patients at home.

Imagine being an immunocompromised cancer patient right now and being asked to leave your home and be exposed to other people in order to see your oncologist viagra dosage for 30 year old. Direct-to-consumer virtual care is the best way to safely care for these patients and without these temporary waivers it wouldn’t be covered by insurance even if you did navigate the clunky apps that are HIPAA compliant. Do we really think the immunocompromised cancer patient feels any more comfortable every normal flu season?.

Is it any more appropriate to ask them to viagra dosage for 30 year old risk exposure to the flu than it is to COVID-19?. And yet we deny them this access in normal times and it quite possibly will be stripped away from them when this crisis is over. Now 300 to 400 patients per day in our health system are seen virtually by their own primary care doctor or specialist for non-COVID related visits.

Not a single one of these would have been reimbursed one month ago and I am highly skeptical I would have gotten approval to viagra dosage for 30 year old use the software that connects us to the patient. Lastly, recall that prior to COVID-19, our system had only found 250 total patients that direct-to-consumer care was value-added and wasn’t restricted by regulation or reimbursement. COVID-19 has been a wake-up call to the whole country and health care is no exception.

It has put priorities in perspective and shined viagra dosage for 30 year old a light on what is truly value-added. For direct-to-consumer virtual care it has shown us what is possible when we get out of our own way. If a regulation has to be removed to allow for care during a crisis then we must question why it exists in the first place.

HIPAA regulation cannot go back to its antiquated practices if we are truly going to shift the viagra dosage for 30 year old focus to patient wellness. CMS and private payors must embrace value-added direct-to-consumer virtual care and allow patients the access they deserve. COVID-19 has forced this industry forward, we cannot allow it to regress and be forgotten when this is over.

Tom Wood is the director of trauma and virtual care for MidMichigan Health, a non-profit health system headquartered in Midland, Michigan, affiliated with Michigan Medicine, the health care division of the viagra dosage for 30 year old University of Michigan. The views and opinions expressed in this commentary are his own.When dealing with all of the aspects of diabetes, it’s easy to let your feel fall to the bottom of the list. But daily care and evaluation is one of the best ways to prevent foot complications.

It’s important to identify your risk viagra dosage for 30 year old factors and take the proper steps in limiting your complications. Two of the biggest complications with diabetes are peripheral neuropathy and ulcer/amputation. Symptoms of peripheral neuropathy include numbness, tingling and/or burning in your feet and legs.

You can slow the progression of developing viagra dosage for 30 year old neuropathy by making it a point to manage your blood sugars and keep them in the normal range. If you are experiencing these symptoms, it is important to establish and maintain a relationship with a podiatrist. Your podiatrist can make sure things are looking healthy and bring things to your attention to monitor and keep a close eye on.

Open wounds or ulcers can develop secondary to trauma, pressure, diabetes, neuropathy or viagra dosage for 30 year old poor circulation. If ulcerations do develop, it’s extremely important to identify the cause and address it. Ulcers can get worse quickly, so it’s necessary to seek immediate medical treatment if you find yourself or a loved one dealing with this complication.

Untreated ulcerations often lead to amputation and can be avoided if proper medical attention is sought right away viagra dosage for 30 year old. There are important things to remember when dealing with diabetic foot care. It’s very important to inspect your feet daily, especially if you have peripheral neuropathy.

You may have a cut or a sore on your feet that you can’t feel, so your body doesn’t alarm you to check your feet. Be gentle when bathing your feet. Moisturize your feet, but not between your toes.

During the virtual clinic’s first two weeks, my team natural viagra turned its attention to getting over 300 providers across 60+ offices virtual so they could see their patients at home. Imagine being an immunocompromised cancer patient right now and being asked to leave your home and be exposed to other people in order to see your oncologist. Direct-to-consumer virtual care is the best way to safely care for these patients and without these temporary waivers it wouldn’t be covered by insurance even if you did navigate the clunky apps that are HIPAA compliant. Do we really think the immunocompromised cancer patient natural viagra feels any more comfortable every normal flu season?.

Is it any more appropriate to ask them to risk exposure to the flu than it is to COVID-19?. And yet we deny them this access in normal times and it quite possibly will be stripped away from them when this crisis is over. Now 300 natural viagra to 400 patients per day in our health system are seen virtually by their own primary care doctor or specialist for non-COVID related visits. Not a single one of these would have been reimbursed one month ago and I am highly skeptical I would have gotten approval to use the software that connects us to the patient. Lastly, recall that prior to COVID-19, our system had only found 250 total patients that direct-to-consumer care was value-added and wasn’t restricted by regulation or reimbursement.

COVID-19 has been a wake-up call natural viagra to the whole country and health care is no exception. It has put priorities in perspective and shined a light on what is truly value-added. For direct-to-consumer virtual care it has shown us what is possible when we get out of our own way. If a regulation has to be removed to allow for care during a crisis then natural viagra we must question why it exists in the first place. HIPAA regulation cannot go back to its antiquated practices if we are truly going to shift the focus to patient wellness.

CMS and private payors must embrace value-added direct-to-consumer virtual care and allow patients the access they deserve. COVID-19 has forced this industry forward, we cannot allow it to regress and be forgotten when natural viagra this is over.

But daily care and natural viagra evaluation is one of the best ways to prevent foot complications.

It’s important to identify your risk factors and take the proper steps in limiting your complications. Two of the biggest complications with diabetes are peripheral neuropathy and ulcer/amputation. Symptoms of peripheral neuropathy include numbness, tingling and/or burning in your natural viagra feet and legs. You can slow the progression of developing neuropathy by making it a point to manage your blood sugars and keep them in the normal range. If you are experiencing these symptoms, it is important to establish and maintain a relationship with a podiatrist.

Your podiatrist can make sure things are looking healthy and bring things to your attention to monitor natural viagra and keep a close eye on. Open wounds or ulcers can develop secondary to trauma, pressure, diabetes, neuropathy or poor circulation. If ulcerations do develop, it’s extremely important to identify the cause and address it. Ulcers can natural viagra get worse quickly, so it’s necessary to seek immediate medical treatment if you find yourself or a loved one dealing with this complication. Untreated ulcerations often lead to amputation and can be avoided if proper medical attention is sought right away.

There are important things to remember when dealing with diabetic foot care. It’s very important to inspect your feet daily, especially if you have peripheral natural viagra neuropathy. You may have a cut or a sore on your feet that you can’t feel, so your body doesn’t alarm you to check your feet. Be gentle when bathing your feet. Moisturize your feet, but not between natural viagra your toes.

Do not treat calluses or corns on your own. Wear clean, dry socks. Never walk barefoot, and natural viagra consider socks and shoes made specifically for patients with diabetes. Kristin Raleigh, D.P.M., is a podiatrist who sees patients at Foot &. Ankle Specialists of Mid-Michigan in Midland.

Severe morning sickness increases the risk of depression both during and after pregnancy, new research has found.Severe morning sickness, known as viagra price hyperemesis gravidarum (HG), is a debilitating condition that affects around this contact form 1-2 per cent of pregnant women in the UK. Far more serious than 'normal' morning sickness, it is one of the most common reasons for hospitalisation during pregnancy and can continue right up until birth. Women can be bed-bound for weeks viagra price on end, suffer dehydration and weight loss and are often unable to work or care for other children they have.The study, by researchers from Imperial College London and Imperial College Healthcare NHS Trust, found that nearly half of women with HG suffered antenatal depression and nearly 30 per cent had postnatal depression.

In women without the condition, just six per cent experienced antenatal depression and seven per cent suffered postnatal depression. The findings are published today in BMJ Open.Dr Nicola Mitchell-Jones, specialist registrar in obstetrics and gynaecology and lead author of the study, believes the viagra price psychological impact of the condition is not taken seriously enough by both healthcare professionals and the wider public."Our study shows that women with HG are around eight times more likely to suffer antenatal depression and four times more likely to have postnatal depression," she says. "Some women in the study even had thoughts of self-harm whilst suffering HG.

These figures are shocking and should viagra price be reflected in the treatment women receive. We need to do much more than simply treat the physical symptoms of HG. Assessment for mental health support should also be routine for any woman with the condition."The study recruited 214 women across three London hospitals -- Chelsea and Westminster Hospital NHS Foundation Trust, Queen viagra price Charlotte's and Chelsea Hospital and St Mary's Hospital (both part of Imperial College Healthcare NHS Trust) -- in the first trimester of pregnancy.Half were recruited on admission to hospital with symptoms of HG.

A similar size control group, without significant nausea or vomiting, were recruited through a midwifery-led antenatal clinic. None of the study viagra price participants had been treated for mental health conditions in the last year. The women were assessed for their psychological wellbeing in the first trimester of pregnancy and six weeks after the birth.Of the women with HG, 49 per cent experienced depression during pregnancy compared to just six per cent in the control group.

Just seven per cent of the control group had postnatal depression, compared to 29 viagra price per cent in the group with HG. Half of the women with HG were forced to take four or more weeks off work during or after pregnancy.Although the study found no direct link between HG and maternal-infant bonding, other research has shown that depression can have a negative effect on this bond. Sadly, eight women with HG recruited to the study terminated their pregnancies, despite originally expressing a desire to keep the baby."Although we can't say that HG was the main reason for those decisions, it may certainly have played a role which is heart-breaking," said Dr Mitchell-Jones, who herself suffered from HG during her first pregnancy in 2018."I was in and out of hospital, spent nearly six months in bed -- but I was lucky enough to have a supportive and employer viagra price and family," she recalled.

"Many women can't afford that amount of time off work or are stay-at-home mums with young children to care for. Too often their partners, relatives viagra price or work colleagues are not providing the support they need because they fail to understand the severity of what these women are going through. We need to educate them, as well as healthcare professionals."Dr Mitchell-Jones hopes that her findings can help to improve understanding of HG and change clinical guidelines on how women with the condition are treated, to include a psychological screening and referral to specialist mental health where required.

Note. Content may be edited for style and length.In 1998, ocean temperatures soared, and the world experienced its first significant viagra price coral bleaching event. From the Great Barrier Reef to Indonesia to Central America, corals turned white and ghostly.

Many of them died viagra price. And this was just a hint as to what was to come. Over the following two decades, viagra price the bleaching became more severe and more frequent, with future predictions suggesting that this trend will continue.

But not all corals are affected equally."Acropora corals are especially susceptible to bleaching and are expected to decline in the future," said Professor Noriyuki Satoh, from the Marine Genomics Unit at the Okinawa Institute of Science and Technology Graduate University (OIST). "This is an issue because Acropora corals are very important. They grow quickly compared to other corals, which helps with reef viagra price growth, island formation, and coastal protection.

And they also provide a habitat for more than a million species of marine organisms."To shed light on whether Acropora corals are genetically equipped to handle a warmer ocean, researchers from OIST, the University of Tokyo and Seikai National Fisheries Research Institute have sequenced and analyzed the genomes of 15 species of Acropora coral, as well as three species of coral from outside this genus.A genome is the complete set of an organism's DNA and contains all its genes, which, over hundreds of millions of years, have undergone random mutations. By analyzing what mutations are shared across different species, scientists can come to understand when organisms evolved and when they split from close viagra price relatives to form new species. This study, published in Molecular Biology and Evolution, has revealed the evolutionary history of Acropora corals, with some surprising results."We found that the Acropora ancestor diverged from other corals around 120 million years ago," Professor Satoh explained.

"And the diversification of Acropora corals, when viagra price we start to see a lot of different species appear, occurred 25-60 million years ago. For both events, this is much earlier than previously thought."This is an important find as it means that Acropora diversified when the world's oceans were much warmer than today. They then viagra price experienced an ice age and survived, which hints that they could have the genetic make-up to handle vast changes in temperature.Lead author Dr.

Chuya Shinzato, a former staff scientist at OIST and now an Associate Professor at the University of Tokyo, analyzed the genomes and found that these 15 species could be divided into four groups. Dr. Shinzato and the group then compared in detail which genes had been conserved and which genes were lost.It was revealed that before this coral genus diversified, several mutations occurred which saw it gain 28 additional gene families.

These genes likely contributed to this diversification, as well as the genus's success at spreading across the globe and its ability to handle a range of temperatures."There were three notable additions from this time period, which could allow these corals to withstand high-stress environments," Professor Satoh said. "Two of these have been identified before and are associated with responding to environmental stress, usually heat."But the finding of the third gene, which encodes DMSP lyase, is significant as this is the first time that a genome analysis has revealed its existence in Acropora corals. This gene allows the corals to produce a compound, dimethyl sulfide, in the water that, when transferred into the air, aids in the formation of clouds.

This suggests that when temperatures get too high, the Acropora corals might be able to create small cloud umbrellas, which can protect them by providing shade and filtering out the light.Although this research has shed light on the evolutionary history of an important genus of coral, Professor Satoh emphasized that it is still hard to say whether this genus will be able to survive the predicted ocean warming and coral bleaching events. "Yes, Acropora corals have withstood vast changes in temperature in the past and, yes, they have these genes that might allow them to somewhat mitigate extreme heat, but the speed in which current climate change is occurring might still exceed their ability to adapt. On the other hand, this vast information of coral genomes provides a basis for future studies of coral biology."Alongside Professor Satoh and Dr.

Shinzato, the research team also included Dr. Konstantin Khalturin, Dr. Jun Inoue, Dr.

Yuki Yoshioka from the University of Tokyo, and Dr. Hiroshi Yamashita and Dr. Go Suzuki from the Seikai National Fisheries Research Institute.Researchers have used insight from a comprehensive genomic analysis of neuroblastoma to learn about the process driving one of the most common childhood solid tumors.

The findings revealed possible approaches for developing precision medicines to improve patient outcomes. St. Jude Children's Research Hospital scientists led the study, which appears today in the journal Nature Communications.The analysis involved whole genome, whole exome and whole transcriptome sequencing of 702 neuroblastoma samples.

The tumors included 23 samples from patients who relapsed. The work identified associations among common mutational traits that researchers hope to exploit therapeutically."This combined analysis of a large cohort of tumors provided insight into previously unrecognized correlations at work in neuroblastoma as well as the discovery of less common driver mutations," said corresponding author Jinghui Zhang, Ph.D., chair of the St. Jude Department of Computational Biology.The co-corresponding authors are Michael Dyer, Ph.D., chair of the St.

Jude Department of Developmental Neurobiology and a Howard Hughes Medical Institute investigator, and Michael Hogarty, M.D., of the Children's Hospital of Philadelphia.Connecting the dots between common mutations and oxidative stressResearchers used a common mutational pattern almost like a fingerprint to identify internal processes fueling the tumor's growth and spread. Investigators knew DNA-damaging molecules called reactive oxygen species and oxidative stress are elevated in neuroblastoma. Reactive oxygen species are generated in the mitochondria of cells.

The analysis found an association between a chromosomal mutation in 65% of neuroblastomas and the DNA-damaging molecules. These tumors have an extra piece of chromosome 17. That piece includes genes expressed in the mitochondria.

The results suggest that mitochondrial gene defects may lead to increased production of reactive oxygen species, fueling tumor growth and drug resistance. advertisement A St. Jude Cloud search of more than 1,000 pediatric tumor genomes from 39 cancer types found the association was not unique.

Researchers reported that more than 20% of samples from another cancer, rhabdomyosarcoma, had increased expression of mitochondrial genes and a pattern of increased oxidative stress. The finding strengthened the newly identified connection between mitochondrial gene defects and the mutational process."Thanks to this analysis, we have a deeper understanding of the alterations driving neuroblastoma, including how tumors form, progress and respond to therapy," Dyer said. "That is the foundation for translational research going forward."Neuroblastoma predictorsNeuroblastoma develops in fetal nerve cells called neuroblasts that fail to mature normally.

While 7 to 10% of childhood cancers are neuroblastoma, the tumor accounts for half of all cancers in infants. This cancer generally begins in the adrenal glands, but it can also start in the chest, the spine or spinal cord regions, abdomen and other areas.Treatment and outcomes vary widely based on patient age. Survival rates for the youngest patients (younger than 18 months old) are about 95%.

For older, high-risk patients, survival rates are only about 50%. advertisement This study reinforced the association between patient age and the mutations driving the disease. For example, the genes MYCN and TERT were commonly altered in patients 3.8 years of age or younger while mutations in ATRX were more frequent in children with a median age of 5.6 years.MYCN, ATRX and a "beautiful convergence"The analysis offered insight into previous research from Dyer and his colleagues.

The researchers noted that while MYCN or ATRX were potent drivers of neuroblastoma, the mutations did not occur together."In most cancers, you would expect to find patients with both mutations who did even worse," Dyer said. "But we never found this combination, which was a surprise."Dyer said this analysis suggests why. MYCN and ATRX mutations induce oxidative stress.

Dyer hypothesized that, when combined, the mutations may be lethal to tumor cells."This was a beautiful convergence of two different approaches to understanding the mutational processes underway inside cells," he said.Recurring, but less common gene alterations The analysis included data from St. Jude, including the St. Jude-Washington University Pediatric Cancer Genome Project.

The Therapeutically Applicable Research to Generate Effective Treatments (TARGET) initiative, managed by the National Cancer Institute. And the Children's Oncology Group, a clinical cooperative trials group.The large number of samples aided efforts to find recurring, but less common neuroblastoma alterations that may be candidates for precision medicines. The newly identified mutations were in the genes FGFR1 and ALK..

A free female version of viagra pilot program to help new and expectant fathers navigate the physical, mental and emotional challenges of becoming a dad will be rolled out in four regions in NSW from today.Health Minister Brad free viagra samples no shipping Hazzard said the ‘Focus on New Fathers’ program will be trialled with men in Northern NSW, Northern and Western Sydney and the Murrumbidgee area. €œAsk any father and they will tell you, becoming a parent is an equally joyous and terrifying experience because your entire routine is turned on its head,” Mr Hazzard said. €œIt is a considerable adjustment which can put tremendous stress on you and on your relationship, so it’s important free viagra samples no shipping to know you are not alone and help is at hand – literally.

€œThis pilot will see texts sent to dads, offering valuable health advice and links into pathways to ensure support options are available, particularly in these uncertain COVID times.” Research has shown men are often reluctant to engage with the health system to get support, despite around one in 10 dads experiencing depression and anxiety in the postnatal period. The pilot, which is being delivered by the University of Newcastle in partnership with NSW Health, will run free viagra samples no shipping over the next year with results helping to improve the program. Men living in the trial site areas will be eligible for the program if they are over the age of 18, their partner is at least 16 weeks pregnant or their baby is up to 24 weeks of age.

They must have a mobile phone capable of receiving and sending text messages. Associate Professor Elisabeth Murphy, Senior Clinical Advisor, Child and Family Health, free viagra samples no shipping said self-care for new fathers is extremely important as the mental and physical wellbeing of both parents has a direct effect on their children. €œReceiving help with health issues early on ensures dads are in the best possible position to care for their new baby and partner,” Associate Professor Murphy said.

€œWe also understand expecting and free viagra samples no shipping new parents may experience more worries about their health and wellbeing in relation to COVID-19. We encourage expectant and new parents, particularly at this time, to reach out for support to their healthcare provider or GP.” ​​​​​​Regional and rural patients now have access to 24-hour critical care under a $21.7 million telestroke service being rolled out across NSW.Patients at Port Macquarie and Coffs Harbour hospitals are the first to benefit from the NSW Telestroke Service, based at Sydney’s Prince of Wales Hospital. Health Minister Brad Hazzard said the revolutionary free viagra samples no shipping service will expand to up to 23 sites over the next three years.

€œThe NSW Telestroke Service will remove geographical barriers and improve outcomes for thousands of regional and rural stroke patients every year, giving them a much greater chance of surviving and leading a normal life,” Mr Hazzard said. €œPeople in regional and rural areas have a far greater risk of hospitalisation from stroke and this vital service will provide them with immediate, life-saving diagnosis and treatment from the state’s leading clinicians.” In 2018-19, 13,651 people were hospitalised for a stroke in NSW. Of those, free viagra samples no shipping 32 per cent were from regional, rural or remote areas.

A successful pilot project in the Hunter New England, Central Coast and Mid North Coast local health districts since 2017 has already helped 1200 patients. The Stroke Foundation’s Chief Executive Officer Sharon McGowan welcomed the launch of the statewide service, free viagra samples no shipping jointly funded by the State and Federal governments. €œWhen a stroke strikes, it kills up to 1.9 million brain cells per minute.

This service will have an enormous impact by providing time-critical, best-practice free viagra samples no shipping treatment that saves lives and reduces lifelong disability,” Ms McGowan said. Prince of Wales Hospital’s Director of Clinical Neuroscience Professor Ken Butcher said. €œThe service links expert stroke clinicians with local emergency physicians to quickly determine the best possible treatment plan for a patient.” ​.
