IntroductionThere has been considerable interest in elucidating the contribution of genetic factors to the development of common diseases can i take viagra twice a day and using this information for better prediction of disease risk. The common disease common variant hypothesis predicts that variants that are common in the population play a role in disease susceptibility.1 Genome-wide association studies (GWAS) can i take viagra twice a day using single nucleotide polymorphism (SNP) arrays were developed as a mechanism by which to investigate these genetic factors and it was hoped this would lead to identification of variants associated with disease risk and subsequent development of predictive tests. Variants identified as associated with particular traits by these studies, for the large part, are SNPs that individually have a minor effect on disease risk and hence, by themselves, cannot be reliably used in disease prediction. Looking at the aggregate impact of these SNPs in the can i take viagra twice a day form of a polygenic score (PGS) appeared to be one possible means of using this information to predict disease.2 It is thought this will be of benefit as our genetic make-up is largely stable from birth and dictates a ‘baseline risk’ on which external influences act and modulate. Therefore, PGS are a potential mechanism to act as a risk predictor by capturing information on this genetic liability.The use of PGS as a predictive biomarker is being explored in a number of different disease areas, including cancer,3 4 psychiatric disorders,5–7 metabolic disorders (diabetes,8 obesity9) and coronary artery disease (CAD).10 The proposed applications range from aiding disease diagnosis, informing selection of therapeutic interventions, improvement of risk prediction, informing disease screening and, on a personal level, informing life planning.

Therefore, genetic can i take viagra twice a day risk information in the form of a PGS is considered to have potential in informing both clinical and individual-level decision-making.Recent advances in statistical techniques, improved computational power and the availability of large data sets have led to rapid developments in this area over the past few years. This has resulted in a variety of approaches to construction of models for score calculation and the investigation of these scores for prediction of common diseases.11 Several review articles aimed at researchers with a working knowledge of this field have been produced.6 11–17 In this article, we provide an overview of the key aspects of PGS construction to assist clinicians and researchers in other areas of academia to gain an understanding of the processes involved in score construction. We also consider the implications of evolving methodologies for the development of applications of can i take viagra twice a day PGS in healthcare.Evolution in polygenic model construction methodologiesTerminology with respect to PGS has evolved over time, reflecting evolving approaches and methodology. Other terms include PGS, polygenic risk score, polygenic load, genotype score, genetic burden, polygenic hazard score, genetic risk score (GRS), metaGRS and allelic risk score. Throughout this article we use the terms polygenic can i take viagra twice a day models to refer to the method used to calculate an output in the form of a PGS.

Different polygenic models can be used to calculate a PGS and analysis of these scores can be used to examine associations with particular markers or to predict an individuals risk of diseases.12Usual practice in calculating PGS is as a weighted sum of a number of risk alleles carried by an individual, where the risk alleles and their weights are defined by SNPs and their measured effects (figure 1).11 Polygenic models have been constructed using a few, hundreds or thousands of SNPs, and more recently SNPs across the whole genome. Consequently, determining which SNPs to include and the disease-associated weighting to assign can i take viagra twice a day to SNPs are important aspects of model construction (figure 2).18 These aspects are influenced by available genotype data and effect size estimates as well as the methodology employed in turning this information into model parameters (ie, weighted SNPs).Polygenic score calculation. This calculation aggregates the SNPs and their weights selected for a polygenic score. Common diseases are thought to be influenced by can i take viagra twice a day many genetic variants with small individual effect sizes, such that meaningful risk prediction necessitates examining the aggregated impact of these multiple variants including their weightings.

GWAS, genome-wide association studies." data-icon-position data-hide-link-title="0">Figure 2 Construction of a can i take viagra twice a day polygenic score. In the process of developing a polygenic score, numerous models are tested and then compared. The model can i take viagra twice a day that performs best (as determined by one or more measures) is then selected for validation in the external data set. GWAS, genome-wide association studies.Changes in data availability over time have had an impact on the approach taken in SNP selection and weighting. Early studies to identify variants associated can i take viagra twice a day with common diseases took the form of candidate gene studies.

The small size of candidate gene studies, the limitation of technologies available for genotyping and stringent significance thresholds meant that these studies investigated fewer variants and those that were identified with disease associations had relatively large effect sizes.19 Taken together, this meant that a relatively small number of variants were available for consideration for inclusion in a polygenic model.20 21 Furthermore, weighting parameters for these few variants were often simplistic, such as counts of the number of risk alleles carried, ignoring their individual effect sizes.16The advent of GWAS enabled assessment of SNPs across the genome, leading to the identification of a larger number of disease-associated variants and therefore more variants suitable for inclusion in a polygenic model. In addition, the increasing number of individuals in the association studies meant that the power of can i take viagra twice a day these studies increased, allowing for more precise estimates of effect sizes.19 Furthermore, some theorised that lowering stringent significance thresholds set for SNP–trait associations could also identify SNPs that might play a part in disease risk.11 16 This resulted in more options with respect to polygenic model parameters of SNPs to include and weights to assign to them. However, the inclusion of more SNPs and direct application of GWAS effect sizes as a weighting parameter does not always equate to better predictive performance.4 16 This is because GWAS do not provide perfect information with respect to the causal SNP, the effect sizes or the number of SNPs that contribute to the trait. Therefore, different can i take viagra twice a day methods have been developed to address these issues and optimise predictive performance of the score. Current common practice is to construct models with different iterations of SNPs and weighting, with assessment of the performance of each to identify the optimum configuration of SNPs and their weights (figure 2).Methods used in SNP selection and weighting assignmentSome methods of model development will initially involve selection of SNPs followed by optimisation of weighting, whereas others may involve optimisation of weightings for all SNPs that have been genotyped using their overall GWAS effect sizes, the linkage disequilibrium (LD) and an estimate of the proportion of SNPs that are expected to contribute to the risk.22LD is the phenomenon where some SNPs are coinherited more frequently with other SNPs due to their close proximity on the genome.

Segments with strong LD between SNPs are can i take viagra twice a day referred to as haplotype blocks. This phenomenon means that GWAS often identify multiple SNPs in the same haplotype block associated with disease and the true causal SNP is not known. As models have started to assess more SNPs, careful consideration can i take viagra twice a day is required to take into account possible correlation between SNPs as a result of this phenomenon. Correlation between SNPs can lead to double counting of SNPs and association redundancy, where multiple SNPs can i take viagra twice a day in a region of LD are identified as being associated with the outcome. This can lead to reduction in the predictive performance of the model.

Therefore, processes for filtering SNPs and using one SNP (tag SNP) to act can i take viagra twice a day as a marker in an area of high LD, through LD thinning, were developed. Through these processes SNPs correlated with other SNPs in a block are removed, by either pruning or clumping. Pruning ignores p value thresholds and ‘eliminates’ SNPs by a process of iterative comparison between a can i take viagra twice a day pair of SNPs to assess if they are correlated, and subsequently could remove SNPs that are deemed to have evidence of association. Clumping (also known as informed pruning) is guided by GWAS p values and chooses the most significant SNP, therefore keeping the most significant SNP within a block.23 This is all done with the aim of pinpointing relatively small areas of the genome that contribute to risk of the trait. Different significance thresholds may be used to select SNPs from this subgroup for inclusion in models.Poor performance of a model can result from imperfect can i take viagra twice a day tagging with the underlying causal SNP.16 This is because the causal SNP that is associated with disease might not be in LD with the tag SNP that is in the model but is in LD with another SNP which is not in the model.

This particularly occurs where the LD and variant frequency differs between population groups.24 An alternate approach to filter SNPs is stepwise regression where SNPs are selected based on how much the SNPs improve the model’s performance. This is a statistical approach and does not can i take viagra twice a day consider the impact of LD or effect size.As described above, early studies used simple weighting approaches or directly applied effect sizes from GWAS as weighting parameters for SNPs. However, application of effect sizes as a weighting parameter directly from a GWAS may not be optimal, due to differences in the population that the GWAS was conducted in and the target population. Also as described above, LD and the fact that not all SNPs may contribute to the trait mean that these effect sizes can i take viagra twice a day from GWAS are imperfect estimates. Therefore, methods have been developed that adjust effect size estimates from GWAS using statistical techniques which make assumptions about factors such as the number of causal SNPs, level of LD between SNPs or knowledge of their potential function to better reflect their impact on a trait.

Numerous statistical methodologies have been can i take viagra twice a day developed to improve weighting with a view to enhancing the discriminative power of a PGS.25 26 Examples of some methodological approaches are LDpred,22 winner’s curse correction,23 empirical Bayes estimation,27 shrinkage regression (Lasso),28 linear mixed models,29 with more being developed or tested. An additional improvement on the methods is to embed non-genetic information (eg, age-specific ORs).6 Determination of which methodology or hybrid of methodologies is most appropriate for various settings and conditions is continuously being explored and is evolving with new statistical approaches developing at a rapid pace.In summary, model development has evolved in an attempt to gain the most from available GWAS data and address some of the issues that arise due to working with data sets which cannot be directly translated into parameters for prediction models. The different approaches taken in SNP selection and weighting, and the impact on the predictive performance can i take viagra twice a day of a model are important to consider when assessing different models. This is because different approaches to PGS modelling can achieve the same or a similar level of prediction. From a health can i take viagra twice a day system implementation perspective, particular approaches may be preferred following practical considerations and trade-offs between obtaining genotype data, processes for score construction and model performance.

In addition, the degree to which these parameters need to be optimised will also be impacted by the input data and validation data set, and the quality control procedures that need to be applied to these data sets.12Sources of input data for score constructionKey to the development of a polygenic model is the availability of data can i take viagra twice a day sets that can provide input parameters for model construction. Genotype data used in model construction can either be available as raw GWAS data or provided as GWAS summary statistics. Data in the raw format are individual-level data from a SNP array and may not have undergone basic quality control such as assessment of missingness, sex discrepancy checks, deviation from Hardy-Weinberg equilibrium, heterozygosity rate, relatedness or assessment for outliers.30 31 Availability of raw GWAS data allows for different polygenic models to be developed because of the richness of the data, however computational issues arise because of the size of the data sets can i take viagra twice a day. Data based on genome sequencing, as opposed to SNP arrays, could also be used in model construction. There have been limited studies of PGS developed from this form of data due to limitations in data availability, which is mainly due to cost restraints.15 32 Individual-level genomic can i take viagra twice a day data are also often not available to researchers due to privacy concerns.Due to these issues, the focus of polygenic model development has therefore been on using well-powered GWAS summary statistics.33 These are available from open access repositories and contain summary information such as the allele positions, ORs, CIs and allele frequency, without containing confidential information on individuals.

These data sets have usually been through the basic quality control measures mentioned above. There are, however, no standards for publicly available files, meaning some further processing steps may be required, in particular when various data can i take viagra twice a day sets are combined for a meta-analysis. Quality control on summary statistics is only possible if information such as missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates is provided.12Processing of GWAS data may include additional quality control steps, imputation and filtering of the SNP information, which can be done at the level of genotype or summary statistics data. SNP arrays used in GWAS only have common SNPs represented on can i take viagra twice a day them as they rely on LD between SNPs to cover the entire genome. As described above, one tag SNP on the array can represent many other SNPs.

Imputation of SNPs is common in GWAS and describes the process of predicting genotypes that have not been directly genotyped but are statistically inferred can i take viagra twice a day (imputed) based on haplotype blocks from a reference sequence.33–35 Often association tests between the imputed SNPs and trait are repeated. As genotype imputation requires individual-level data, researchers have proposed summary statistics imputation as a mechanism to infer the association between untyped SNPs and a trait. The performance of imputation has been evaluated and shown that, with certain limitations, summary statistics imputation is an efficient and cost-effective methodology to can i take viagra twice a day identify loci associated with traits when compared with imputation done on genotypes.36An alternative source of input data for the selection of SNPs and their weightings is through literature or in existing databases, where already known trait-associated SNPs and their effect sizes are used as the input parameters in model development. A number of studies have taken this approach37 38 and it is possible to use multiple sources when developing various polygenic models and establishing the preferred parameters to use.Currently, there does not appear to be one methodology that works across all contexts and traits, each trait will need to be assessed to determine which method is the most suitable for the trait being evaluated. For example, four different polygenic model construction strategies were explored for three skin cancer subtypes4 by using data on SNPs and their can i take viagra twice a day effect sizes from different sources, such as the latest GWAS meta-analysis results, the National Human Genome Research Institute (NHGRI) EBI GWAS catalogue, UK Biobank GWAS summary statistics with different thresholds and GWAS summary statistics with LDpred.

In this setting for basal cell carcinoma and melanoma, the meta-analysis and catalogue-derived models were found to perform similarly but that the latter was ultimately used as it included more SNPs. For squamous cell carcinoma the meta-analysis-derived model performed better than the catalogue-derived model can i take viagra twice a day. This demonstrates how each disease subtype, model construction strategy and data set can have their own limitations and advantages.Knowledge of the sources of input data and its subsequent use can i take viagra twice a day in model development is important in understanding the limitations of available models. Models that are developed using data sets that reflect the population in which prediction is to be carried out will perform better. For example, data collected from a symptomatic or high-risk population may not be suitable as an input data set for can i take viagra twice a day the development of a polygenic model that will be used for disease prediction in the general population.

Large GWAS studies were previously focused on high-risk individuals, such as patients with breast cancer with a strong family history or known pathogenic variants in BRCA1 or BRCA2. These studies would not be suitable for the development of PGS for use in the general population but can inform can i take viagra twice a day risk assessment in high-risk individuals. The source of the data for SNP selection and weighting also has implications for downstream uses and validation. For example, variant frequency and LD patterns can vary between populations and this can translate to poor performance of the polygenic model if the external validation population is different from that can i take viagra twice a day of the input data set.39–41 Furthermore, the power and validity of polygenic analyses are influenced by the input data sources.12 42From a model to a scorePGS can be calculated using one of the methodologies discussed above. The resulting PGS units of measurement depend on which measurement is used for the weighting.12 For example, the weightings may have been calculated based on logOR for discrete traits or linear regression coefficient (β/beta) in continuous traits from univariate regression tests carried out in the GWAS.

The resulting scores are then usually transformed to a standard normal distribution to give scores ranging from −1 can i take viagra twice a day to 1, or 0 to 100 for ease of interpretation. This enables further examination of the association between the score and a trait and the predictive ability of different scores generated by different models. Similar to other biomarker analyses, this involves using the PGS as a predictor of a trait can i take viagra twice a day with other covariates (eg, age, smoking, and so on) added, if appropriate, in a target sample. Examination of differences in the distribution of scores in cases and controls, or by examining differences in traits between different strata of PGS can enable assessment of predictive ability (figure 3). Common practice is for individual-level PGS values to be used to can i take viagra twice a day stratify populations into distinct groups of risk based on percentile cut-off or threshold values (eg, the top 1%).Example distribution of polygenic scores across a population.

Thresholds can be set to stratify risk as low (some), average (most) and high (some)." data-icon-position data-hide-link-title="0">Figure 3 Example distribution of polygenic scores across a population. Thresholds can be set to stratify risk as low (some), average (most) and high (some).Model validationPolygenic model development is reliant on further data sets for model testing and validation and the composition can i take viagra twice a day of these data sets is important in ensuring that the models are appropriate for a particular purpose. The development of a model to calculate a PGS involves refinement of the previously discussed input parameters, and selection of the ‘best’ of several can i take viagra twice a day models based on performance (figure 2). Therefore, a testing/training data set is often required to assess the model’s ability to accurately predict the trait of interest. This is often a data set that can i take viagra twice a day is independent of the base/input/discovery data set.

It may comprise a subset of the discovery data set that is only used for testing and was not included in the initial development of the model but should ideally be a separate independent data set.Genotype and phenotype data are needed in these data sets. Polygenic models are used to calculate PGS for individuals in the training data set and regression analysis is performed can i take viagra twice a day with the PGS as a predictor of a trait. Other covariates may also be included, if appropriate. This testing phase can be considered can i take viagra twice a day a process for identifying models with better overall performance and/or informing refinements needed. Hence, this phase often involves comparison of different models that are developed using the same input data set to identify those models that have optimal performance.The primary purpose is to determine which model best discriminates between cases and controls.

The area under the curve (AUC) or the C-statistic is the most commonly used measure in assessing can i take viagra twice a day discriminative ability. It has been criticised as being an insensitive measure that is not able to fully capture all aspects of predictive ability. For instance, in some instances, AUC can remain unchanged between models but can i take viagra twice a day the individuals within are categorised into a different risk group.43 Alternative metrics that have been used to evaluate model performance include increase in risk difference, integrated discrimination improvement, R2 (estimate of variance explained by the PGS after covariate adjustment), net classification index and the relative risk (highest percentile vs lowest percentile). A clear understanding on how to interpret the performance within various settings is important in determining which model is most suitable.44As per normal practice when developing any prediction model, polygenic models with the optimal performance in a testing/training data set should be further validated in external data sets. External data sets are critical in validation of models and assessment of generalisability, hence must also conform to the desired situations in can i take viagra twice a day which a model is to be used.

The goal is to find a model with suitable parameters of predictive performance in data sets outside of those in which it was developed. Ideally, external validation can i take viagra twice a day requires replication in independent data sets. Few existing polygenic models have been validated to this extent, the focus being rather on the development of new models rather than evaluation of existing ones. One example where replication has been carried out is in the field of CAD, where the GPSCAD45 and metaGRSCAD10 polygenic models (both developed using can i take viagra twice a day UK Biobank data) were evaluated in a Finnish population cohort.46 Predictive ability was found to be lower in the Finnish population. This is likely to be due to the differences in genetic structure of this population and the population of the data set used for polygenic model development can i take viagra twice a day.

Research is ongoing to evaluate polygenic models in other populations and strategies are being developed to ensure the same performance when used more widely, possibly through reweighting and adjustment of the scores.47Moving towards clinical applicationsPGS are thought to be useful information that could improve risk estimation and provide an avenue for disease prevention and deciding treatment strategies. There are indications from can i take viagra twice a day a number of fields that genetic information in the form of PGS can act as independent biomarkers and aid stratification.11 16 48 However, the clinical benefits of stratification using a PGS and the implications for clinical practice are only just beginning to be examined. The use of PGS as part of existing risk prediction tools or as a stand-alone predictor has been suggested. This latter option may be true for diseases where knowledge or predictive ability with other risk factors is limited, such as in prostate cancer.49 In either case, polygenic models need to be individually examined to determine suitability and applicability for the specific clinical question.50 Despite can i take viagra twice a day some commercial companies developing PGS,51 52 currently PGS are not an established part of clinical practice.Integration into clinical practice requires evaluation of a PGS-based test. An important concept to consider in this regard is the distinction between an assay and a test.

This has been previously discussed with respect to genetic test evaluation.53 54 It is worth examining this concept as applied can i take viagra twice a day to PGS, as their evaluation is reliant on a clear understanding of the test to be offered. As outlined by Zimmern and Kroese,54 the method used to analyse a substance in a sample is considered the assay, whereas a test is the use of an assay within a specific context. With respect to PGS, the process of can i take viagra twice a day developing a model to derive a score can be considered the assay, while the use of this model for a particular disease, population and purpose can be considered the test. This distinction is important when assessing if studies are reporting on assay performance as opposed to test performance. It is our view that, with respect to polygenic models, progress has been made can i take viagra twice a day with respect to assay development, but PGS-based tests are yet to be developed and evaluated.

This can enable a clearer understanding of their potential clinical utility and issues that may arise for clinical implementation.11 18 55 It is clear that this is still an evolving field, and going forward different models may be required for different traits due to their underlying genetic architecture,26 different clinical contexts and needs.Clinical contexts where risk stratification is already established practice are most likely where implementation of PGS will occur first. Risk prediction models based on non-genetic factors have been developed for many conditions and are used in clinical care, for example, in cardiovascular disease over 100 such models exist.56 In such contexts, how a PGS and its ability to predict risk compared with, or improves on, these existing models can i take viagra twice a day is being investigated.3 44 57–61 The extent to which PGS improves prediction, as well as the cost implications of including this, is likely to impact on implementation.Integration of PGS into clinical practice, for any application, requires robust and validated mechanisms to generate these scores. Therefore, given the numerous models available, an assessment of their suitability as part of a test is required. Parameters or guidelines with respect to aspects of model performance and metrics that could assist in selecting can i take viagra twice a day the model to take forward as a PGS-based test are limited and need to be addressed. Currently, there are different mechanisms to generate PGS and have arisen in response to the challenges in aggregating large-scale genomic data for prediction.

For example, a review reported 29 PGS models for breast cancer from can i take viagra twice a day 22 publications.62 Due to there being a number of different methodologies to generate a score, numerous models may exist for the same condition and each of the resulting models could perform differently. Models may perform differently because the population, measured outcome or context of the development data sets used to generate the models is diverse, for example, a score for risk of breast cancer versus a breast cancer subtype.44 63 This diversity, alongside the lack of established best practice and standardised reporting in publications, makes comparison and evaluation of polygenic models for use in can i take viagra twice a day clinical settings challenging. It is clear that moving the field forward is reliant on transparent reporting and evaluation. Recommendations for can i take viagra twice a day best practices on the reporting of polygenic models in literature have been proposed14 64 as well as a database,65 66 which could allow for such comparisons. Statements and guidelines for risk prediction model development, such as the Genetic Risk Prediction Studies and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD), already exist, but are not consistently used.

TRIPOD explicitly covers the development and validation of prediction models for both diagnosis and prognosis, for all medical domains.One clear issue is generalisability and drop in performance of polygenic models once they are applied in a population group different from the one in which they were developed.22 46 67–70 This is an ongoing challenge in genomics as most GWAS, from which most PGS are being developed, have been conducted in European-Caucasian populations.71 Efforts to improve representation are underway72 and there are attempts to reweight/adjust scores when applied to different population groups which are showing some potential but need further research.47 Others have demonstrated that models developed in more diverse population groups have improved performance when applied to external data sets in different populations.24 73 It is important to consider this issue when moving towards clinical applications as it may pose an ethical challenge if the PGS is not generalisable.A greater understanding of can i take viagra twice a day different complex traits and the impact of pleiotropy is only beginning to be investigated.74 There is growing appreciation of the role of pleiotropy as multiple variants have been identified to be associated with multiple traits and exert diverse effects, providing insight into overlapping mechanisms.75 76 This, together with the impact of population stratification, genetic relatedness, ascertainment and other sources of heterogeneity leading to spurious signals and reduced power in genetic association studies, all impacting on the predictive ability of PGS in different populations and for different diseases.While many publications report on model development and evaluation, often there is a lack of clarity on intended purpose,50 77 leading to uncertainties as to the clinical pathways in which implementation is envisaged. A clear description of intended use within clinical pathways is a central component in evaluating the use of an application with any form of PGS and in considering practical implications, such as mechanisms of obtaining the score, incorporation into health records, interpretation of scores, relevant cut-offs for intervention initiation, mechanisms for feedback of results and costs, among other issues. These parameters will also be impacted can i take viagra twice a day by the polygenic model that is taken forward for implementation. Meaning that there are still some important questions that need to be addressed to determine how and where PGS could work within current healthcare systems, particularly at a population level.78It is widely accepted that genotyping using arrays is a lower cost endeavour in comparison to genome sequencing, making the incorporation of PGS into routine healthcare an attractive proposition. However, we can i take viagra twice a day were unable to find any studies reporting on the use or associated costs of such technology for population screening.

Studies are beginning to examine use case scenarios and model cost-effectiveness, but this has only been in very few, specific investigations.79 80 Costs will also be influenced by the testing technology and by the downstream consequences of testing, which is likely to differ depending on specific applications that are developed and the pathways in which such tests are incorporated. This is particularly the case in screening or primary care settings, can i take viagra twice a day where such testing is currently not an established part of care pathways and may require additional resources, not least as a result of the volume of testing that could be expected. Moving forward, the clinical role of PGS needs to be developed further, including defining the clinical applications as well as supporting evidence, for example, on the effect of clinical outcomes, the feasibility for use in routine practice and cost-effectiveness.ConclusionThere is a large amount of diversity in the PGS field with respect to model development approaches, and this continues to evolve. There is rapid progress which is being driven by the availability of larger data sets, primarily from GWAS and concomitant developments can i take viagra twice a day in statistical methodologies. As understanding and knowledge develops, the usefulness and appropriateness of polygenic models for different diseases and contexts are being explored.

Nevertheless, this is still an emerging field, with a variable evidence base demonstrating can i take viagra twice a day some potential. The validity of PGS needs to be clearly demonstrated, and their applications evaluated prior to clinical implementation..

IntroductionThere has been considerable interest in buy viagra canada elucidating the contribution of genetic factors to the development Cost of cialis 5mg of common diseases and using this information for better prediction of disease risk. The common disease common variant hypothesis predicts that variants that are common in the population play a role in disease susceptibility.1 Genome-wide association studies (GWAS) using single nucleotide polymorphism (SNP) arrays were developed buy viagra canada as a mechanism by which to investigate these genetic factors and it was hoped this would lead to identification of variants associated with disease risk and subsequent development of predictive tests. Variants identified as associated with particular traits by these studies, for the large part, are SNPs that individually have a minor effect on disease risk and hence, by themselves, cannot be reliably used in disease prediction. Looking at the aggregate impact of these SNPs in the form of a polygenic score (PGS) appeared to be one possible means of using this information to predict disease.2 It is thought buy viagra canada this will be of benefit as our genetic make-up is largely stable from birth and dictates a ‘baseline risk’ on which external influences act and modulate.

Therefore, PGS are a potential mechanism to act as a risk predictor by capturing information on this genetic liability.The use of PGS as a predictive biomarker is being explored in a number of different disease areas, including cancer,3 4 psychiatric disorders,5–7 metabolic disorders (diabetes,8 obesity9) and coronary artery disease (CAD).10 The proposed applications range from aiding disease diagnosis, informing selection of therapeutic interventions, improvement of risk prediction, informing disease screening and, on a personal level, informing life planning. Therefore, genetic risk information in the form of a PGS is considered to have potential in informing both clinical and individual-level decision-making.Recent advances in statistical techniques, improved computational power and the availability of buy viagra canada large data sets have led to rapid developments in this area over the past few years. This has resulted in a variety of approaches to construction of models for score calculation and the investigation of these scores for prediction of common diseases.11 Several review articles aimed at researchers with a working knowledge of this field have been produced.6 11–17 In this article, we provide an overview of the key aspects of PGS construction to assist clinicians and researchers in other areas of academia to gain an understanding of the processes involved in score construction. We also consider the implications of evolving methodologies for the development of applications of PGS in healthcare.Evolution in polygenic model construction methodologiesTerminology with respect to PGS buy viagra canada has evolved over time, reflecting evolving approaches and methodology.

Other terms include PGS, polygenic risk score, polygenic load, genotype score, genetic burden, polygenic hazard score, genetic risk score (GRS), metaGRS and allelic risk score. Throughout this article we use the terms polygenic models to refer to the method used to calculate an output in the form of a PGS buy viagra canada. Different polygenic models can be used to calculate a PGS and analysis of these scores can be used to examine associations with particular markers or to predict an individuals risk of diseases.12Usual practice in calculating PGS is as a weighted sum of a number of risk alleles carried by an individual, where the risk alleles and their weights are defined by SNPs and their measured effects (figure 1).11 Polygenic models have been constructed using a few, hundreds or thousands of SNPs, and more recently SNPs across the whole genome. Consequently, determining which SNPs to include and the disease-associated weighting to assign to SNPs are important aspects of model construction buy viagra canada (figure 2).18 These aspects are influenced by available genotype data and effect size estimates as well as the methodology employed in turning this information into model parameters (ie, weighted SNPs).Polygenic score calculation.

This calculation aggregates the SNPs and their weights selected for a polygenic score.

In the process of developing a polygenic score, numerous models are tested and then compared. The model that performs best (as determined by one or more measures) is then buy viagra canada selected for validation in the external data set. GWAS, genome-wide association studies.Changes in data availability over time have had an impact on the approach taken in SNP selection and weighting.

Early studies to identify variants associated with common diseases took the form of buy viagra canada candidate gene studies. The small size of candidate gene studies, the limitation of technologies available for genotyping and stringent significance thresholds meant that these studies investigated fewer variants and those that were identified with disease associations had relatively large effect sizes.19 Taken together, this meant that a relatively small number of variants were available for consideration for inclusion in a polygenic model.20 21 Furthermore, weighting parameters for these few variants were often simplistic, such as counts of the number of risk alleles carried, ignoring their individual effect sizes.16The advent of GWAS enabled assessment of SNPs across the genome, leading to the identification of a larger number of disease-associated variants and therefore more variants suitable for inclusion in a polygenic model. In addition, the increasing number of individuals in the association studies meant that the power of these studies increased, allowing for more precise buy viagra canada estimates of effect sizes.19 Furthermore, some theorised that lowering stringent significance thresholds set for SNP–trait associations could also identify SNPs that might play a part in disease risk.11 16 This resulted in more options with respect to polygenic model parameters of SNPs to include and weights to assign to them. However, the inclusion of more SNPs and direct application of GWAS effect sizes as a weighting parameter does not always equate to better predictive performance.4 16 This is because GWAS do not provide perfect information with respect to the causal SNP, the effect sizes or the number of SNPs that contribute to the trait.

Therefore, different methods have been developed to address these issues and buy viagra canada optimise predictive performance of the score. Current common practice is to construct models with different iterations of SNPs and weighting, with assessment of the performance of each to identify the optimum configuration of SNPs and their weights (figure 2).Methods used in SNP selection and weighting assignmentSome methods of model development will initially involve selection of SNPs followed by optimisation of weighting, whereas others may involve optimisation of weightings for all SNPs that have been genotyped using their overall GWAS effect sizes, the linkage disequilibrium (LD) and an estimate of the proportion of SNPs that are expected to contribute to the risk.22LD is the phenomenon where some SNPs are coinherited more frequently with other SNPs due to their close proximity on the genome. Segments with strong LD buy viagra canada between SNPs are referred to as haplotype blocks. This phenomenon means that GWAS often identify multiple SNPs in the same haplotype block associated with disease and the true causal SNP is not known.

As models have started to assess more SNPs, careful consideration is required to take into account possible correlation buy viagra canada between SNPs as a result of this phenomenon. Correlation between SNPs can lead to double counting of SNPs and association redundancy, where multiple SNPs in a region of buy viagra canada LD are identified as being associated with the outcome. This can lead to reduction in the predictive performance of the model. Therefore, processes for filtering SNPs and using one SNP (tag SNP) to act as a marker in an buy viagra canada area of high LD, through LD thinning, were developed.

Through these processes SNPs correlated with other SNPs in a block are removed, by either pruning or clumping. Pruning ignores p value thresholds and ‘eliminates’ SNPs by a process of iterative comparison between a pair of SNPs to assess if they are correlated, and subsequently could remove SNPs that buy viagra canada are deemed to have evidence of association. Clumping (also known as informed pruning) is guided by GWAS p values and chooses the most significant SNP, therefore keeping the most significant SNP within a block.23 This is all done with the aim of pinpointing relatively small areas of the genome that contribute to risk of the trait. Different significance thresholds may be used to select SNPs from this subgroup for inclusion in models.Poor performance of a model can result from imperfect tagging with the underlying causal SNP.16 This is because the causal SNP that is associated with disease might not be in LD with the buy viagra canada tag SNP that is in the model but is in LD with another SNP which is not in the model.

This particularly occurs where the LD and variant frequency differs between population groups.24 An alternate approach to filter SNPs is stepwise regression where SNPs are selected based on how much the SNPs improve the model’s performance. This is a statistical approach and does not consider the impact of buy viagra canada LD or effect size.As described above, early studies used simple weighting approaches or directly applied effect sizes from GWAS as weighting parameters for SNPs. However, application of effect sizes as a weighting parameter directly from a GWAS may not be optimal, due to differences in the population that the GWAS was conducted in and the target population. Also as described above, LD and the fact that not all SNPs may contribute to the trait mean that buy viagra canada these effect sizes from GWAS are imperfect estimates.

Therefore, methods have been developed that adjust effect size estimates from GWAS using statistical techniques which make assumptions about factors such as the number of causal SNPs, level of LD between SNPs or knowledge of their potential function to better reflect their impact on a trait. Numerous statistical methodologies have been developed to improve weighting with a view to enhancing the discriminative power of a PGS.25 26 Examples of some methodological approaches are LDpred,22 winner’s curse correction,23 empirical Bayes estimation,27 shrinkage regression (Lasso),28 buy viagra canada linear mixed models,29 with more being developed or tested. An additional improvement on the methods is to embed non-genetic information (eg, age-specific ORs).6 Determination of which methodology or hybrid of methodologies is most appropriate for various settings and conditions is continuously being explored and is evolving with new statistical approaches developing at a rapid pace.In summary, model development has evolved in an attempt to gain the most from available GWAS data and address some of the issues that arise due to working with data sets which cannot be directly translated into parameters for prediction models. The different approaches taken in SNP selection and weighting, buy viagra canada and the impact on the predictive performance of a model are important to consider when assessing different models.

This is because different approaches to PGS modelling can achieve the same or a similar level of prediction. From a health system implementation perspective, particular approaches may be preferred buy viagra canada following practical considerations and trade-offs between obtaining genotype data, processes for score construction and model performance. In addition, the degree to which these parameters need to be optimised will also be impacted by the input data and validation data set, and the buy viagra canada quality control procedures that need to be applied to these data sets.12Sources of input data for score constructionKey to the development of a polygenic model is the availability of data sets that can provide input parameters for model construction. Genotype data used in model construction can either be available as raw GWAS data or provided as GWAS summary statistics.

Data in the raw format are individual-level data from a SNP array and may not have buy viagra canada undergone basic quality control such as assessment of missingness, sex discrepancy checks, deviation from Hardy-Weinberg equilibrium, heterozygosity rate, relatedness or assessment for outliers.30 31 Availability of raw GWAS data allows for different polygenic models to be developed because of the richness of the data, however computational issues arise because of the size of the data sets. Data based on genome sequencing, as opposed to SNP arrays, could also be used in model construction. There have been limited studies of PGS developed from this form of data due to limitations in data availability, which is mainly due to cost restraints.15 32 Individual-level genomic data are also often not available to researchers due to privacy concerns.Due to these issues, the focus of polygenic model development has therefore been on using well-powered GWAS summary statistics.33 These are available from open buy viagra canada access repositories and contain summary information such as the allele positions, ORs, CIs and allele frequency, without containing confidential information on individuals. These data sets have usually been through the basic quality control measures mentioned above.

There are, however, no standards for buy viagra canada publicly available files, meaning some further processing steps may be required, in particular when various data sets are combined for a meta-analysis. Quality control on summary statistics is only possible if information such as missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates is provided.12Processing of GWAS data may include additional quality control steps, imputation and filtering of the SNP information, which can be done at the level of genotype or summary statistics data. SNP arrays used in GWAS only have buy viagra canada common SNPs represented on them as they rely on LD between SNPs to cover the entire genome. As described above, one tag SNP on the array can represent many other SNPs.

Imputation of SNPs is common in GWAS and buy viagra canada describes the process of predicting genotypes that have not been directly genotyped but are statistically inferred (imputed) based on haplotype blocks from a reference sequence.33–35 Often association tests between the imputed SNPs and trait are repeated. As genotype imputation requires individual-level data, researchers have proposed summary statistics imputation as a mechanism to infer the association between untyped SNPs and a trait. The performance of imputation has been evaluated and shown that, with certain limitations, summary statistics imputation is an efficient and cost-effective methodology to identify loci associated with traits when compared with imputation done on genotypes.36An alternative source of buy viagra canada input data for the selection of SNPs and their weightings is through literature or in existing databases, where already known trait-associated SNPs and their effect sizes are used as the input parameters in model development. A number of studies have taken this approach37 38 and it is possible to use multiple sources when developing various polygenic models and establishing the preferred parameters to use.Currently, there does not appear to be one methodology that works across all contexts and traits, each trait will need to be assessed to determine which method is the most suitable for the trait being evaluated.

For example, four different polygenic model construction strategies were explored for three skin cancer subtypes4 by using data on SNPs and their effect sizes from different sources, such as the latest GWAS meta-analysis results, the National Human Genome Research Institute (NHGRI) EBI GWAS catalogue, UK Biobank GWAS summary statistics with different thresholds buy viagra canada and GWAS summary statistics with LDpred. In this setting for basal cell carcinoma and melanoma, the meta-analysis and catalogue-derived models were found to perform similarly but that the latter was ultimately used as it included more SNPs. For squamous cell carcinoma the meta-analysis-derived model buy viagra canada performed better than the catalogue-derived model. This demonstrates how each disease subtype, model construction strategy and data set can have their own buy viagra canada limitations and advantages.Knowledge of the sources of input data and its subsequent use in model development is important in understanding the limitations of available models.

Models that are developed using data sets that reflect the population in which prediction is to be carried out will perform better. For example, data collected from a buy viagra canada symptomatic or high-risk population may not be suitable as an input data set for the development of a polygenic model that will be used for disease prediction in the general population. Large GWAS studies were previously focused on high-risk individuals, such as patients with breast cancer with a strong family history or known pathogenic variants in BRCA1 or BRCA2. These studies would not be buy viagra canada suitable for the development of PGS for use in the general population but can inform risk assessment in high-risk individuals.

The source of the data for SNP selection and weighting also has implications for downstream uses and validation. For example, variant frequency and LD patterns can vary between populations and this can translate to poor performance of the polygenic model if the external validation population is different from that of the input data set.39–41 Furthermore, the power buy viagra canada and validity of polygenic analyses are influenced by the input data sources.12 42From a model to a scorePGS can be calculated using one of the methodologies discussed above. The resulting PGS units of measurement depend on which measurement is used for the weighting.12 For example, the weightings may have been calculated based on logOR for discrete traits or linear regression coefficient (β/beta) in continuous traits from univariate regression tests carried out in the GWAS. The resulting scores are buy viagra canada then usually transformed to a standard normal distribution to give scores ranging from −1 to 1, or 0 to 100 for ease of interpretation.

This enables further examination of the association between the score and a trait and the predictive ability of different scores generated by different models. Similar to other biomarker analyses, this involves using the PGS as a predictor of a trait with other covariates (eg, age, smoking, and so on) added, if appropriate, buy viagra canada in a target sample. Examination of differences in the distribution of scores in cases and controls, or by examining differences in traits between different strata of PGS can enable assessment of predictive ability (figure 3). Common practice is for individual-level PGS values to be buy viagra canada used to stratify populations into distinct groups of risk based on percentile cut-off or threshold values (eg, the top 1%).Example distribution of polygenic scores across a population.

Thresholds can be set to stratify risk as low (some), average (most) and high (some)." data-icon-position data-hide-link-title="0">Figure 3 Example distribution of polygenic scores across a population. Thresholds can buy viagra canada be set to stratify risk as low (some), average (most) and high (some).Model validationPolygenic model development is reliant on further data sets for model testing and validation and the composition of these data sets is important in ensuring that the models are appropriate for a particular purpose. The development of a model to calculate a PGS involves refinement of the previously discussed input parameters, and selection of the ‘best’ of several models based on performance buy viagra canada (figure 2). Therefore, a testing/training data set is often required to assess the model’s ability to accurately predict the trait of interest.

This is buy viagra canada often a data set that is independent of the base/input/discovery data set. It may comprise a subset of the discovery data set that is only used for testing and was not included in the initial development of the model but should ideally be a separate independent data set.Genotype and phenotype data are needed in these data sets. Polygenic models are buy viagra canada used to calculate PGS for individuals in the training data set and regression analysis is performed with the PGS as a predictor of a trait. Other covariates may also be included, if appropriate.

This testing phase can be considered buy viagra canada a process for identifying models with better overall performance and/or informing refinements needed. Hence, this phase often involves comparison of different models that are developed using the same input data set to identify those models that have optimal performance.The primary purpose is to determine which model best discriminates between cases and controls. The area under the curve (AUC) or the C-statistic is the most commonly used measure buy viagra canada in assessing discriminative ability. It has been criticised as being an insensitive measure that is not able to fully capture all aspects of predictive ability.

For instance, in some instances, AUC can remain unchanged between models but the individuals within are categorised into a different risk group.43 Alternative metrics that have buy viagra canada been used to evaluate model performance include increase in risk difference, integrated discrimination improvement, R2 (estimate of variance explained by the PGS after covariate adjustment), net classification index and the relative risk (highest percentile vs lowest percentile). A clear understanding on how to interpret the performance within various settings is important in determining which model is most suitable.44As per normal practice when developing any prediction model, polygenic models with the optimal performance in a testing/training data set should be further validated in external data sets. External data sets are critical in buy viagra canada validation of models and assessment of generalisability, hence must also conform to the desired situations in which a model is to be used. The goal is to find a model with suitable parameters of predictive performance in data sets outside of those in which it was developed.

Ideally, external validation requires replication buy viagra canada in independent data sets. Few existing polygenic models have been validated to this extent, the focus being rather on the development of new models rather than evaluation of existing ones. One example where replication buy viagra canada has been carried out is in the field of CAD, where the GPSCAD45 and metaGRSCAD10 polygenic models (both developed using UK Biobank data) were evaluated in a Finnish population cohort.46 Predictive ability was found to be lower in the Finnish population. This is likely to be due to the differences in genetic structure of this population and the population of the data set used for polygenic model development buy viagra canada.

Research is ongoing to evaluate polygenic models in other populations and strategies are being developed to ensure the same performance when used more widely, possibly through reweighting and adjustment of the scores.47Moving towards clinical applicationsPGS are thought to be useful information that could improve risk estimation and provide an avenue for disease prevention and deciding treatment strategies. There are indications from a number of fields that genetic information in the form of PGS can act as independent biomarkers and aid stratification.11 16 48 However, the clinical benefits of stratification using a PGS and the implications for clinical practice are only buy viagra canada just beginning to be examined. The use of PGS as part of existing risk prediction tools or as a stand-alone predictor has been suggested. This latter option may be true for diseases where knowledge or predictive ability with other risk factors is limited, such as in prostate cancer.49 In either case, polygenic models need to be individually examined to determine suitability and applicability for the specific clinical question.50 Despite some commercial companies developing PGS,51 52 currently PGS are not an established part of clinical practice.Integration buy viagra canada into clinical practice requires evaluation of a PGS-based test.

An important concept to consider in this regard is the distinction between an assay and a test. This has been previously discussed with respect to genetic test evaluation.53 54 buy viagra canada It is worth examining this concept as applied to PGS, as their evaluation is reliant on a clear understanding of the test to be offered. As outlined by Zimmern and Kroese,54 the method used to analyse a substance in a sample is considered the assay, whereas a test is the use of an assay within a specific context. With respect to PGS, the process of developing a model to buy viagra canada derive a score can be considered the assay, while the use of this model for a particular disease, population and purpose can be considered the test.

This distinction is important when assessing if studies are reporting on assay performance as opposed to test performance. It is our view that, with respect to buy viagra canada polygenic models, progress has been made with respect to assay development, but PGS-based tests are yet to be developed and evaluated. This can enable a clearer understanding of their potential clinical utility and issues that may arise for clinical implementation.11 18 55 It is clear that this is still an evolving field, and going forward different models may be required for different traits due to their underlying genetic architecture,26 different clinical contexts and needs.Clinical contexts where risk stratification is already established practice are most likely where implementation of PGS will occur first. Risk prediction models based on non-genetic factors have been developed for many conditions and are used in clinical care, for example, in cardiovascular disease over 100 such models exist.56 In such contexts, how a PGS and its ability to predict risk compared with, or improves on, these existing models is buy viagra canada being investigated.3 44 57–61 The extent to which PGS improves prediction, as well as the cost implications of including this, is likely to impact on implementation.Integration of PGS into clinical practice, for any application, requires robust and validated mechanisms to generate these scores.

Therefore, given the numerous models available, an assessment of their suitability as part of a test is required. Parameters or buy viagra canada guidelines with respect to aspects of model performance and metrics that could assist in selecting the model to take forward as a PGS-based test are limited and need to be addressed. Currently, there are different mechanisms to generate PGS and have arisen in response to the challenges in aggregating large-scale genomic data for prediction. For example, a review reported 29 PGS models for breast cancer from 22 publications.62 Due to there being a number of buy viagra canada different methodologies to generate a score, numerous models may exist for the same condition and each of the resulting models could perform differently.

Models may perform differently because the population, measured outcome or context of the development data sets used to generate the models is diverse, for example, a score for risk of breast cancer versus a breast cancer subtype.44 63 This diversity, alongside the lack of established best practice and standardised reporting in publications, makes buy viagra canada comparison and evaluation of polygenic models for use in clinical settings challenging. It is clear that moving the field forward is reliant on transparent reporting and evaluation. Recommendations for best practices on the buy viagra canada reporting of polygenic models in literature have been proposed14 64 as well as a database,65 66 which could allow for such comparisons. Statements and guidelines for risk prediction model development, such as the Genetic Risk Prediction Studies and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD), already exist, but are not consistently used.

TRIPOD explicitly covers the development and validation of prediction models for both diagnosis and prognosis, for all medical domains.One clear issue is generalisability and drop in performance of polygenic models once they are applied in a population group different from the one in which they were developed.22 46 67–70 This is an ongoing challenge in genomics as most GWAS, from which most PGS are being developed, have been conducted in European-Caucasian populations.71 Efforts to improve representation are underway72 and there are attempts to reweight/adjust scores when applied to different population groups which are showing some potential but need further research.47 Others have demonstrated that models developed in more diverse population groups have improved performance when applied to external data sets in different populations.24 73 It is important to consider this issue when moving towards clinical applications as it may pose an ethical challenge if the PGS is not generalisable.A greater understanding of different complex traits and the impact of pleiotropy is only beginning to be investigated.74 There is growing appreciation of the role of pleiotropy as multiple variants have been identified to be associated with multiple traits and exert diverse effects, providing insight into overlapping mechanisms.75 76 This, together with the impact of population stratification, genetic relatedness, ascertainment and other sources of heterogeneity leading to spurious signals and reduced power in genetic association studies, all impacting on the predictive ability of PGS in different populations and for different diseases.While many publications report on model development and evaluation, often there is a lack of clarity on intended purpose,50 77 leading to uncertainties as to the clinical pathways in which buy viagra canada implementation is envisaged. A clear description of intended use within clinical pathways is a central component in evaluating the use of an application with any form of PGS and in considering practical implications, such as mechanisms of obtaining the score, incorporation into health records, interpretation of scores, relevant cut-offs for intervention initiation, mechanisms for feedback of results and costs, among other issues. These parameters will also be impacted by the polygenic model that is buy viagra canada taken forward for implementation. Meaning that there are still some important questions that need to be addressed to determine how and where PGS could work within current healthcare systems, particularly at a population level.78It is widely accepted that genotyping using arrays is a lower cost endeavour in comparison to genome sequencing, making the incorporation of PGS into routine healthcare an attractive proposition.

However, we were unable to find any studies reporting on the use or associated costs buy viagra canada of such technology for population screening. Studies are beginning to examine use case scenarios and model cost-effectiveness, but this has only been in very few, specific investigations.79 80 Costs will also be influenced by the testing technology and by the downstream consequences of testing, which is likely to differ depending on specific applications that are developed and the pathways in which such tests are incorporated. This is particularly the case in screening or primary care settings, where such testing is currently buy viagra canada not an established part of care pathways and may require additional resources, not least as a result of the volume of testing that could be expected. Moving forward, the clinical role of PGS needs to be developed further, including defining the clinical applications as well as supporting evidence, for example, on the effect of clinical outcomes, the feasibility for use in routine practice and cost-effectiveness.ConclusionThere is a large amount of diversity in the PGS field with respect to model development approaches, and this continues to evolve.

There is rapid progress which is being driven by the availability of larger data sets, primarily from GWAS and concomitant developments buy viagra canada in statistical methodologies. As understanding and knowledge develops, the usefulness and appropriateness of polygenic models for different diseases and contexts are being explored. Nevertheless, this is still an emerging field, with a variable evidence base demonstrating some buy viagra canada potential. The validity of PGS needs to be clearly demonstrated, and their applications evaluated prior to clinical implementation..

After voters expanded Medicaid in conservative states like Missouri and Oklahoma, health care advocates are renewing a push for expansion in Mississippi and other Southern states where Republican leaders have long been opposed.They say the changing tide has followed rising income inequality, joblessness and pressure from hospitals http://deepgreenyoga.com/196/ in economic turmoil — issues exacerbated by the erectile dysfunction viagra."There have been, in the last two years, votes 100mg viagra pill on Medicaid expansion in some of the most conservative, Republican-leaning states in the country, and Medicaid expansion has never lost," said Eliot Fishman, senior director of Health Policy at Families USA, a health care advocacy organization.Fishman spoke Thursday during an online forum about Medicaid expansion hosted by the Mississippi Health Advocacy Program and the Mississippi Center for Justice.Medicaid expansion is an option under the health care overhaul that then-President Barack Obama signed into law in 2010. Many Democratic-controlled states agreed to expansion, mainly for people whose jobs don't provide health insurance.However, since Republican Donald Trump became president in January 2017, voters in Idaho, Nebraska, Utah, Oklahoma, Maine and most recently Missouri have approved Medicaid expansion by ballot measures 100mg viagra pill. In Virginia, legislators passed Medicaid expansion after Democrats gained power."This is clearly an issue which you can no longer shut down voter interest by just saying the word 'Obamacare,' " Fishman said. "That power has waned."There are now 12 states — including Mississippi, Georgia, Alabama, Texas, South Carolina, North Carolina, Tennessee and Florida — that have 100mg viagra pill not expanded Medicaid. A newly formed collaborative, "Southerners for Medicaid Expansion," is aiming to put 100mg viagra pill pressure on the holdouts.Medicaid is a government health insurance program for the needy, aged, blind and disabled, and it is paid by state and federal money.

Because Mississippi is poor, the federal government pays nearly 78% of the cost.Under expansion, the federal government pays 90% of the cost in any state.About 25% of Mississippi's nearly 3 million residents are already enrolled in Medicaid, and opponents have said they don't want more people taking part in a government program.Roy Mitchell, executive director of the Mississippi Health Advocacy Program, said hospitals are in desperate need of the dollars. Uncompensated care costs in Mississippi exceed $600 million annually, according to a 2019 statement from the Mississippi Hospital Association."Let's face it, providers are businessmen 100mg viagra pill. Despite their marketing, they are inherently out to make a profit, and they are going to have to wake up in Mississippi," Mitchell said. "I'm sure erectile dysfunction treatment did a good job of doing that."Addressing ailing hospitals 100mg viagra pill has been controversial. Republican Gov 100mg viagra pill.

Tate Reeves and leaders in the Republican-controlled Mississippi Legislature have opposed Medicaid expansion. Reeves has 100mg viagra pill said money should go instead to federally funded community health centers that help people in need.Reeves has said repeatedly that the viagra has not changed his mind about expansion. And Republican House Speaker Philip Gunn told reporters this month that he also remains opposed.The Mississippi Hospital Association in 2019 proposed "Mississippi Cares," which it called Medicaid reform but not expansion. It was modeled after 100mg viagra pill an Indiana program enacted under then-Gov. Mike Pence 100mg viagra pill.

It would expand Medicaid eligibility while setting $20 monthly premium payments and copays. The proposal gained no traction during this year's Mississippi legislative session.While advocates for Medicaid expansion say they are hopeful, they acknowledge difficulties.Out of the 12 nonexpansion states, Mississippi and Florida are the only two with a ballot initiative process.Mississippi law says that for an initiative to be placed on the ballot, at least 106,190 certified signatures must be gathered, and those must be evenly divided among the five congressional districts that Mississippi used 100mg viagra pill 20 years ago. Even if signature-gathering is successful, the earliest a proposal is likely to be on the ballot is November 2022."For all the stars to align in a ballot initiative ... There's got to be a commitment on the part 100mg viagra pill of providers in Mississippi, I think, and we have to also look realistically at the amount of resources that it takes to do a ballot initiative," Mitchell said. "But it is certainly not out of reach."Consultations via tablets, laptops and phones linked patients and doctors when society shut down 100mg viagra pill in early spring.

Telehealth visits dropped with the reopening, but they're still far more common than before and now there's a push to make them widely available in the future.Permanently expanding access will involve striking a balance between costs and quality, dealing with privacy concerns and potential fraud, and figuring out how telehealth can reach marginalized patients, including people with mental health problems."I don't think it is ever going to replace in-person visits, because sometimes a doctor needs to put hands on a patient," said CMS Administrator Seema Verma, the Trump administration's leading advocate for telehealth.Caveats aside, "it's almost a modern-day house call," she added."It's fair to say that telemedicine was in its infancy prior to the viagra, but it's come of age this year," said Murray Aitken of the data firm IQVIA, which tracks the impact.In the depths of the erectile dysfunction shutdown, telehealth accounted for more than 40% of primary care visits for patients with traditional Medicare, up from a tiny 0.1% sliver before the public health emergency. As the government's flagship health care 100mg viagra pill program, Medicare covers more than 60 million people, including those age 65 and older, and younger disabled people.A recent poll of older adults by the University of Michigan Institute for Healthcare Policy &. Innovation found that more than 100mg viagra pill 7 in 10 are interested in using telehealth for follow-ups with their doctor, and nearly 2 out of 3 feel comfortable with video conferences.But privacy was an issue, especially for those who hadn't tried telehealth. The poll found 27% of older adults who had not had a telemedicine visit were concerned about privacy, compared with 17% of those who tried it.Those who tried telehealth weren't completely sold. About 4 in 5 were concerned the doctor couldn't physically examine them, and 64% worried the quality wasn't as good."After the initial excitement, in the afterglow, patients realize 'I can't get my treatment,' or 'You can't see this thing in the back of my throat over the computer,' " said Dr 100mg viagra pill.

Gary LeRoy of Dayton, Ohio, a primary care doctor and president of the American Academy of Family Physicians.For Medicare beneficiary Jean Grady of Westford, Vermont, telemedicine was a relief. She needed a checkup required by Medicare to continue receiving supplies for her 100mg viagra pill wearable insulin pump. Being in a high risk group for erectile dysfunction treatment, Grady worried about potential 100mg viagra pill exposure in a doctor's waiting room, and even more about losing her diabetes supplies if she missed Medicare's checkup deadline."I would have had to go back to taking insulin by syringe," she said.Grady prepared for the virtual visit by calling her clinician's tech department and downloading teleconference software. She says she would do some future visits by video, but not all. For example, people with diabetes need periodic blood tests, and their feet must be checked for signs of circulatory problems.Still, quite a few follow-ups "could be done very efficiently and be just as useful to the physician and myself as going in and seeing them 100mg viagra pill in person," Grady said.Many private insurance plans, including those in Medicare Advantage, offer some level of telemedicine coverage.But traditional Medicare has restricted it to rural residents, who generally had to travel to specially designated sites to connect.Under the erectile dysfunction public health emergency, the administration temporarily waived Medicare's restrictions so enrollees anywhere could use telemedicine.

Patients could connect from home. Making such changes permanent would require legislation from Congress, but there's bipartisan 100mg viagra pill interest.Sen. Lamar Alexander, chairman of the Senate Health, Education, Labor and Pensions Committee, says he'd like to see broader access, without breaking the bank."Our job should be to ensure that change is done with the goals of better outcomes and better patient experiences, at a lower 100mg viagra pill cost," said Alexander, R-Tenn.That's a tall order.Payment will be a sticky obstacle. For now, Medicare is paying clinicians on par for virtual and in-person visits."Policymakers seems to be in a rush to pass legislation, but I think it is worth taking a little more time," said Juliette Cubanski, a Medicare expert with the nonpartisan Kaiser Family Foundation. "Fraud is one 100mg viagra pill big area that policymakers need to be cognizant of."Fraud-busters agree.Telehealth is so new that "we don't have at this point a real sense of where the huge risks lie," said Andrew VanLandingham, a senior lawyer with the Health and Human Services inspector general's office.

"We are sort of in an experimental phase."Despite the risks, advocates see opportunities.Expanded Medicare telehealth could:help move the nation closer to a long-sought goal of treating mental health the same as physical conditions. Sen. Ron Wyden, D-Ore., wants to use telemedicine as a springboard to improve mental health care. IQVIA data shows 60% of psychiatric consults took place by telehealth during the shutdown.increase access for people living in remote communities, in low-income urban areas and even nursing homes. Medicare's research shows low-income beneficiaries have had similar patterns of using telehealth for primary care as program enrollees overall.improve coordination of care for people with chronic health conditions, a goal that requires patient and persistent monitoring.

Chronic care accounts for most program spending.University of Michigan health policy expert Mark Fendrick says Medicare should figure out what services add value for patients' health and taxpayers' wallets, and pay just for those.Telehealth "was an overnight sensation," said Fendrick. "Hopefully it's not a one-hit wonder."As the wind howled and the rain slammed down, a team of nurses, respiratory therapists and a doctor worked through the night to care for 19 tiny babies as Hurricane Laura slammed southwestern Louisiana.The babies, some on ventilators or eating through a feeding tube, seemed to weather the storm just fine, said Dr. Juan Bossano, the medical director of the neonatal intensive care unit at Lake Charles Memorial Hospital for Women. "They did very well. They tolerated it very well.

We had a very good day," he said.Laura made landfall early Thursday morning as a Category 4 storm, packing top winds of 150 mph (241 kph), and pushing a storm surge as high as 15 feet in some areas.Hours before it made landfall, officials had to move the babies from the women's hospital to the main hospital in the system after it became clear that storm surge could inundate the women's hospital, located on the southern end of Lake Charles. The hospital has its own generator and hospital administrator Alesha Alford said it was built to withstand hurricane force winds. But in the http://djblast.com/mls-allstar-game-after-party/ single story facility, there's no room to move up and storm surge in that area was expected to hit nine feet. In a roughly two-hour operation the babies in the intensive care unit were transferred by ambulance to Lake Charles Memorial Hospital, a ten-story facility on the northern side of the city. Trucks carried needed equipment such as incubators.Alford said the storm hadn't yet hit but "the skies looked very ominous." She said everyone pitched in to get supplies moved to the other hospital."It went as smooth as could be because we had everyone helping," she said.Alford said three mothers who couldn't be discharged from the women's hospital were also transferred.

Two of them had their newborns with them while the child of the third mom was in the intensive care unit. Parents of the other children in the neonatal intensive care unit couldn't stay with them during the storm because there wasn't enough room so Bossano said one nurse was tasked with calling parents to keep them informed of how their children were doing. Bossano occasionally posted updates on Facebook.Once they got situated at the larger hospital and the winds picked up, Alford said the patients were moved into the hallways. To "protect our babies," mattresses were pushed up against the windows to prevent flying glass although none of the windows ended up breaking.She said as huge gusts of wind started coming in, they could feel the building vibrate. In addition to Bossano, the medical staff consisted of two neonatal nurse practitioners, 14 nurses and three respiratory therapists who worked on 12-hour shifts.

Some of the staff slept on air mattresses in the hallway, Alford said. After making it through the hurricane, the plan was to have the babies stay in Lake Charles. While electricity was out in the city, the hospital has its own generator. But Alford said the city's water system has been so heavily damaged that it ultimately forced them to transfer the babies as well as other patients to other hospitals around the state Friday.Both Alford and Bossano repeatedly praised the nursing staff for their work in caring for the babies that in some cases were born weighing only a pound or two. Some of the nursing staff lost their houses in the storm, and they were worried about their own families, but they put those concerns aside to care for their tiny patients."Really the nurses and the respiratory therapists are the heroes here," Bosanno said.

"They showed that very clearly the way they performed."There aren’t many hospital visitors amid the erectile dysfunction treatment viagra. But, if you were to walk through intensive-care units at one New York City hospital, you’d see internet-connected speakers—about the size of a stack of Post-it Notes—affixed to the bedrails of some patient beds.It’s part of a project by two Weill Cornell Medicine doctors to help family members speak with ICU patients, often intubated or otherwise not able to hold up a phone themselves, from afar.“The patients could be completely sedated, they could be in a coma,” but families still want to be there with them, said Dr. Marc Schiffman, an interventional radiologist and one of the doctors who spearheaded bringing the devices into ICUs.The speakers, now in 11 units at Weill Cornell, are part of a two-way communication system from company Relay, originally developed as a walkie-talkie system of sorts for children to stay in touch with their parents throughout the day. Users on one end record snippets of conversation using a mobile app, which are automatically played out loud through the small speaker.Users on the other end push a button on the device to record a response.“Whenever (families) have a story they want to recount, they can just talk into their phone,” Schiffman said. €œIt gives the families a sense of autonomy (and) connection,” even when the patient can’t respond.The effort, dubbed the VoiceLove Project, began about four months ago, at the height of the erectile dysfunction treatment viagra in New York City.Families and other visitors were no longer allowed inside Weill Cornell, but still wanted a way to connect with patients who were sick with erectile dysfunction treatment.

Initially, that involved a nurse standing in the ICU and holding up a phone or tablet so families could see the patient—a task that took time out of their already busy day, potentially exposed them to erectile dysfunction treatment and often meant using scarce personal protective equipment.“It really wasn’t a practical solution,” said Dr. Tamatha Fenster, a minimally invasive gynecologic surgeon.So Fenster and Schiffman began brainstorming hands-free technologies they could install directly at the bedside. Schiffman drove to a local Target store and bought a few Relay walkie-talkie devices. After testing it with families and patients in the ICU, the two decided it was a “grand slam,” Schiffman said.Since March, hospitals have been trying new ways to keep patients connected to families at home, said Bill Flatley, senior service delivery manager at consulting firm OST. He said he’s mainly seen hospitals repurpose technology usually used for telemedicine, like tablets and cameras mounted on telemedicine carts.It’s likely hospitals will have to continue to restrict visitors, at least as long as there’s uncertainty around erectile dysfunction treatment.

So it’s integral for staff to figure out processes that make it easy for families to talk to patients—without putting an additional burden on clinicians or expecting them to serve as tech support.For Fenster and Schiffman, deploying walkie-talkies in the ICU for the first time took some leg work.To scale the walkie-talkie system, Schiffman reached out to Relay’s team via the company’s website, and the company agreed to donate roughly 130 devices and waived the per-user subscription fee. The doctors and Relay have continued to work together on best practices for using the devices in ICUs, a use case Relay is marketing and could sell to other hospitals, according to Jon Schniepp, Relay’s senior vice president of marketing.But Fenster and Schiffman couldn’t just bring walkie-talkies into the ICU. In the hospital setting, there are additional quality and privacy concerns. To address those, the doctors created a disposable case, which made it easier to keep the device sterile and blocked passersby from accidentally pressing the button that would transmit sounds to a family’s Relay app.The two spent thousands of dollars out of their own pockets to devise the best case design, Fenster said, working with an industrial designer in New Jersey to 3D print different models. The final plastic case, customized with the phrase “VoiceLove” on the front, costs about $10 per case to print and ship.

They’ve started reaching out to acute-care and post-acute facilities in California, Texas and other erectile dysfunction treatment hot spots to explain how the VoiceLove Project works, hoping to connect other groups with Relay and share the case design. But the doctors say they’re still working out the logistics of getting the equipment to interested organizationsWhen Dr. George Wanna saw how devastated St. George Hospital University Medical Center was by an explosion that shook Beirut, he felt a need to help his hometown. The Aug.

4 blast in the city’s harbor ravaged St. George’s, so Wanna launched a GoFundMe page to help the hospital, where a good friend of his, Dr. Alexander Nehme, is chief medical officer.At deadline, more than $86,600 had been raised, with a goal of $100,000. €œThis is the first time in their 140-year history when St. George’s Hospital was damaged so severely that it is unable to function,” said Wanna, chair of the otolaryngology department at New York Eye and Ear Infirmary of Mount Sinai and Mount Sinai Beth Israel in New York.

€¨St. George Hospital even remained open during Lebanon’s 15-year civil war, a conflict that wracked Beirut and forced Wanna to spend much of his childhood in bomb shelters. Wanna is also working with Mount Sinai to send medical supplies. €œSt. George Hospital is in need of everything needed to run a hospital—beds, ventilators, protective equipment.” The tragedy also affected Wanna’s family.

His parents weren’t home when the blast struck and were unharmed. But “my parents’ home was severely damaged by the blast. Sadly, we lost the lives of several of my dad’s relatives,” he said via email. Wanna, who spent his residency at Mount Sinai, is grateful to the system. €œThey have given me a chance to have the kind of life I could never have hoped for—they helped me build a home and a life in this great country.”.

After voters expanded Medicaid in conservative states like Missouri and Oklahoma, health care advocates are renewing a push for expansion in Mississippi and other Southern states where Republican leaders have long been opposed.They say buy viagra canada the changing tide has followed rising income inequality, joblessness and pressure from hospitals in economic turmoil — issues exacerbated by the erectile dysfunction viagra."There have been, in the last two years, votes on Medicaid expansion in some of the most conservative, Republican-leaning states in the country, and Medicaid expansion has never lost," said Eliot Fishman, senior director of Health Policy at Families USA, a health care advocacy organization.Fishman spoke Thursday during an online forum about Medicaid expansion hosted by the Mississippi Health Advocacy Program and the Mississippi Center for Justice.Medicaid expansion is an option under the health care overhaul that then-President Barack Obama signed into law in 2010. Many Democratic-controlled states agreed to expansion, mainly for people whose buy viagra canada jobs don't provide health insurance.However, since Republican Donald Trump became president in January 2017, voters in Idaho, Nebraska, Utah, Oklahoma, Maine and most recently Missouri have approved Medicaid expansion by ballot measures. In Virginia, legislators passed Medicaid expansion after Democrats gained power."This is clearly an issue which you can no longer shut down voter interest by just saying the word 'Obamacare,' " Fishman said. "That power has waned."There are now 12 states — including Mississippi, Georgia, Alabama, Texas, South Carolina, North Carolina, Tennessee and Florida — buy viagra canada that have not expanded Medicaid.

A newly formed collaborative, "Southerners for Medicaid Expansion," is aiming to put pressure on the holdouts.Medicaid is a government health insurance buy viagra canada program for the needy, aged, blind and disabled, and it is paid by state and federal money. Because Mississippi is poor, the federal government pays nearly 78% of the cost.Under expansion, the federal government pays 90% of the cost in any state.About 25% of Mississippi's nearly 3 million residents are already enrolled in Medicaid, and opponents have said they don't want more people taking part in a government program.Roy Mitchell, executive director of the Mississippi Health Advocacy Program, said hospitals are in desperate need of the dollars. Uncompensated care costs in Mississippi exceed $600 million annually, according to a 2019 statement from buy viagra canada the Mississippi Hospital Association."Let's face it, providers are businessmen. Despite their marketing, they are inherently out to make a profit, and they are going to have to wake up in Mississippi," Mitchell said.

"I'm sure erectile dysfunction treatment did a good job of doing that."Addressing ailing buy viagra canada hospitals has been controversial. Republican Gov buy viagra canada. Tate Reeves and leaders in the Republican-controlled Mississippi Legislature have opposed Medicaid expansion. Reeves has said money should go instead to federally funded community health centers that help people in need.Reeves has said repeatedly that the viagra buy viagra canada has not changed his mind about expansion.

And Republican House Speaker Philip Gunn told reporters this month that he also remains opposed.The Mississippi Hospital Association in 2019 proposed "Mississippi Cares," which it called Medicaid reform but not expansion. It was buy viagra canada modeled after an Indiana program enacted under then-Gov. Mike Pence buy viagra canada. It would expand Medicaid eligibility while setting $20 monthly premium payments and copays.

The proposal gained no traction during this year's Mississippi legislative session.While advocates for Medicaid expansion say they are hopeful, they acknowledge difficulties.Out of the 12 nonexpansion states, Mississippi and Florida are the only two with a ballot initiative process.Mississippi law says that for an buy viagra canada initiative to be placed on the ballot, at least 106,190 certified signatures must be gathered, and those must be evenly divided among the five congressional districts that Mississippi used 20 years ago. Even if signature-gathering is successful, the earliest a proposal is likely to be on the ballot is November 2022."For all the stars to align in a ballot initiative ... There's got to be a commitment on the part of providers in buy viagra canada Mississippi, I think, and we have to also look realistically at the amount of resources that it takes to do a ballot initiative," Mitchell said. "But it is certainly not out of reach."Consultations via tablets, laptops and buy viagra canada phones linked patients and doctors when society shut down in early spring.

Telehealth visits dropped with the reopening, but they're still far more common than before and now there's a push to make them widely available in the future.Permanently expanding access will involve striking a balance between costs and quality, dealing with privacy concerns and potential fraud, and figuring out how telehealth can reach marginalized patients, including people with mental health problems."I don't think it is ever going to replace in-person visits, because sometimes a doctor needs to put hands on a patient," said CMS Administrator Seema Verma, the Trump administration's leading advocate for telehealth.Caveats aside, "it's almost a modern-day house call," she added."It's fair to say that telemedicine was in its infancy prior to the viagra, but it's come of age this year," said Murray Aitken of the data firm IQVIA, which tracks the impact.In the depths of the erectile dysfunction shutdown, telehealth accounted for more than 40% of primary care visits for patients with traditional Medicare, up from a tiny 0.1% sliver before the public health emergency. As the government's flagship health care program, Medicare covers more buy viagra canada than 60 million people, including those age 65 and older, and younger disabled people.A recent poll of older adults by the University of Michigan Institute for Healthcare Policy &. Innovation found that more than 7 in 10 are interested in using buy viagra canada telehealth for follow-ups with their doctor, and nearly 2 out of 3 feel comfortable with video conferences.But privacy was an issue, especially for those who hadn't tried telehealth. The poll found 27% of older adults who had not had a telemedicine visit were concerned about privacy, compared with 17% of those who tried it.Those who tried telehealth weren't completely sold.

About 4 in 5 were concerned the doctor couldn't physically examine them, and buy viagra canada 64% worried the quality wasn't as good."After the initial excitement, in the afterglow, patients realize 'I can't get my treatment,' or 'You can't see this thing in the back of my throat over the computer,' " said Dr. Gary LeRoy of Dayton, Ohio, a primary care doctor and president of the American Academy of Family Physicians.For Medicare beneficiary Jean Grady of Westford, Vermont, telemedicine was a relief. She needed a checkup required by Medicare to continue receiving supplies for her wearable insulin pump buy viagra canada. Being in a high risk group for erectile dysfunction treatment, Grady worried about potential exposure in a doctor's waiting room, and even more about losing her diabetes supplies if she missed Medicare's checkup deadline."I would have had to go back to taking insulin by syringe," she said.Grady prepared for the virtual visit by calling her clinician's tech department and downloading teleconference buy viagra canada software.

She says she would do some future visits by video, but not all. For example, people with diabetes need periodic blood tests, and their feet buy viagra canada must be checked for signs of circulatory problems.Still, quite a few follow-ups "could be done very efficiently and be just as useful to the physician and myself as going in and seeing them in person," Grady said.Many private insurance plans, including those in Medicare Advantage, offer some level of telemedicine coverage.But traditional Medicare has restricted it to rural residents, who generally had to travel to specially designated sites to connect.Under the erectile dysfunction public health emergency, the administration temporarily waived Medicare's restrictions so enrollees anywhere could use telemedicine. Patients could connect from home. Making such changes permanent would require buy viagra canada legislation from Congress, but there's bipartisan interest.Sen.

Lamar Alexander, buy viagra canada chairman of the Senate Health, Education, Labor and Pensions Committee, says he'd like to see broader access, without breaking the bank."Our job should be to ensure that change is done with the goals of better outcomes and better patient experiences, at a lower cost," said Alexander, R-Tenn.That's a tall order.Payment will be a sticky obstacle.

We have integrated general pediatricians, mental care professionals, behavioral therapists and child psychiatrists, along with public health nurses and the county’s child welfare,” said UC Davis volunteer clinical faculty member and pediatrician Katy Carlsen, who has helped spearhead these efforts and donated funds to make this clinic possible.

A UC Davis endowment has also been established to generate funds.UC Davis viagra advert pediatrician Albina Gogo has been part of a workgroup for the past three years to create this clinic and works there part time.“Adverse Childhood Experiences (ACEs), including being in the foster care system, can create trauma and impact the health and wellbeing of children. The CIRCLE clinic provides comprehensive, trauma-informed, culturally-sensitive health care to help instill resilience into these children’s lives, resulting in better long-term health outcomes and more stable foster home placements,” Gogo said.So far, the team has seen about a dozen pediatric patients.“I was super excited when I heard about it,” said Monica Foote, a former foster child who is now a foster parent, who came to the clinic for the first time this month. €œI experienced a lot of trauma in the system and it did affect viagra advert my physical health.

One way New York State is trying to address that barrier is with the Special Housing Disregard that allows certain members of Managed Long Term Care or FIDA plans to keep more of their income to pay for rent or other shelter costs, rather than having to "spend down" their "excess income" or spend-down on the cost of Medicaid home care. The special income standard for housing expenses helps pay for housing expenses to help certain buy viagra canada nursing home or adult home residents to safely transition back to the community with MLTC.

What is viagra for women

This author what is viagra for women has published on various medical topics and is obviously on several lists as a potential reviewer for papers on subjects of which he has only slight detailed knowledge. There appears to be no definition of, or qualifications for, a peer reviewer other than that he or she is, rightly or wrongly, perceived to be an expert in a particular field.About a million research papers are published each year and researchers are pressurised to publish because grants, enhanced reputations and rewards may follow (perhaps including a Nobel prize). Peer review is one way for what is viagra for women reputable journals to promote good science. But there are numerous problems as outlined by Richard Smith, a previous editor of the British Medical Journal.1Peer reviewers are usually busy people and often provide their opinions without charge.

Journal editors, unless they reject submission independently, must choose and trust that reviewers are up to date especially concerning potentially important recent developments.For the purposes of this account, a differentiation is made between research studies and research trials. Studies are solely observational and replications are unusual because surrounding circumstances often what is viagra for women change with the passage of time. In contrast, trials are interventional. Trials should address predefined specific questions and the methods used should contain sufficient information what is viagra for women to allow exact replication.

Replication of trials is problematic because of the expenses involved and details of the exact methods used in the original trial may not be comprehensive. Double-blind randomised placebo-controlled research trials are said to be gold standard, but comparative trials are more important. The former what is viagra for women only suggests that treatments given were more effective than placebo. Reviewers need to know is whether treatments are better than a known effective treatment.Traditionally studies and trials comprise titles, abstracts, introduction, methods, results, discussion, conclusions and references.Reviewers should ensure that …AbstractAt the beginning of 2020, the outbreak of erectile dysfunction treatment in China has brought great impact on the society, economy and life.

This article introduces current status of what is viagra for women Chinese postgraduate medical students under this epidemic situation in combination with the author's own experience from four aspects. Professional spirit, professional knowledge, learning status and protective measures.IntroductionA novel erectile dysfunction has been discovered and confirmed since the first case of unidentified pneumonia was confirmed in Wuhan, China, in December 2019.1 2 The disease caused by this novel viagra was officially named erectile dysfunction treatment by the WHO on 12 January 2020. Since the outbreak in China, the numbers of confirmed cases and deaths have rapidly increased. erectile dysfunction treatment has been clarified as a grade B infectious disease, others of which include what is viagra for women severe acute respiratory syndrome and highly pathogenic avian influenza, and is treated according to the protocol for grade A infectious diseases.

erectile dysfunction treatment is the seventh known erectile dysfunction-induced disease that involves of the respiratory system in human beings. The other two potentially life-threatening erectile dysfunction-induced diseases are severe acute respiratory syndrome and Middle East respiratory syndrome.3 4 This novel erectile dysfunction-induced pneumonia is transmitted from what is viagra for women person to person and is highly infectious, with high susceptibility among the general population. The erectile dysfunction responsible for erectile dysfunction treatment has a long incubation period and diverse clinical features, seriously impacting normal work and life throughout the country. As of 13 April 2020, erectile dysfunction treatment had been recognised in over 200 countries, with a total of 1 784 364 laboratory-confirmed cases and 111 832 deaths, and these numbers have since continued to rise.On 23 January 2020, the Chinese government immediately blocked the city of Wuhan and cut off all outside contact to stop the spread of erectile dysfunction treatment.

Other cities what is viagra for women successively announced closure of public places and restricted the flow of people. At the time of this writing, the Chinese Ministry of Education had stated that no student was allowed to return to school until further notification. Some postgraduate medical students residing at school were isolated in safe what is viagra for women places. Some others who had returned home for holiday were restricted to their local residence and prohibited to return to the hospital or medical school for studies or clinical work.

We herein describe the status and situation of postgraduate medical students in China under the influence of erectile dysfunction treatment.Encouragement and promotion of the professional spirit of postgraduate medical studentsAt the frontline of the fight against erectile dysfunction treatment, many medical staff members around the country have devoted their full power without hesitation while ignoring their own personal safety. Their teachers, colleagues and what is viagra for women friends have also participated in this battle. Such behaviour demonstrates the humanitarian nature of medicine, which involves healing the wounded and rescuing the dying. This vivid lesson helps medical students to internalise medical ethical principles through emotional penetration and thus what is viagra for women deepens their understanding and strengthens their beliefs.

It benefits society to cultivate a spirit of benevolence among medical students and to train postgraduate medical students to engage in positive behaviour. In recent years, the position of the medical humanities in medical education has gradually improved. The combination of medical what is viagra for women humanities and medical knowledge is regarded as a successful medical education, which manifests scientific and human brilliance. Such education could help medical students to realise the transformation from medical ethical cognition to medical ethical behaviour in their future career.Use of professional knowledge to assist othersMedical students can help their relatives and friends to recognise the symptoms of pneumonia early according to their professional knowledge.

The diagnosis of erectile dysfunction treatment is based on a combination of epidemiological information, clinical symptoms, CT imaging findings and what is viagra for women laboratory tests according to the standards of either the WHO or the National Health Commission of China. Although medical students were not in the hospital and had no access to CT or test kits, they generally have a higher level of professional judgement than people in the general population with respect to medical knowledge and patients’ symptoms. For example, if a person within a medical student’s neighbourhood develops a fever and cough and has a travel history from Wuhan, the student can advise him or her to go to the hospital in a timely manner. Postgraduate medical students can also educate what is viagra for women the people around them, which helps the public to realise the importance of prevention and comply with regulations formulated by the country.

Medical students can also serve as volunteers within the community and use their professional knowledge to make more contributions to community residents.Non-stop learning despite suspension of classesThe sudden outbreak of this novel erectile dysfunction disrupted normal teaching and studying in the field of medical education. Non-stop learning via online teaching despite suspension of classes was put forward by what is viagra for women the ministry of education. During the disease outbreak, online lectures and learning tutorials were adopted to avoid unnecessary aggregation of people and the associated risk of .5 Basic medical courses such as physiology, pathology and biology are relatively easy to study by video or electronic books. However, clinical medicine courses such as surgery are not suitable for online study.

Because medicine is a practical science, it cannot break away from clinics and patients, and even simulation training cannot achieve a real-world what is viagra for women effect. Many universities lack the ability to use the computers or software required to conduct online teaching courses, record teaching videos and prepare teaching documents such as text, picture, audio and animation. Students living in rural areas with underdeveloped networks and poor hardware facilities may find it difficult to meet the requirements of online learning. During this special period in China, self-study has become an important what is viagra for women skill for medical students.

Students of different majors have different learning styles. Dermatology students can review photographs of what is viagra for women lesions to improve their skills in differential diagnosis. Internal medicine students can analyse complex cases to exercise their logical ability. Surgery students can learn more about internal medicine to become more comprehensive surgeons.

Additionally, online learning allows students to restart long-forgotten projects, what is viagra for women modify research papers and complete unfinished work. They can also review the literature in a field of interest, create an outline of future research and contemplate their career plan. All doctors in China are willing to apply for assistance from the National Natural Science Foundation of China, a famous and widely used research what is viagra for women fund. Online application usually starts in March every year, but in 2020, it was postponed until April because of the epidemic.

This gave medical students more time to carefully prepare for their application under the guidance of a mentor.Effective measures to ensure the health of medical studentsAlthough the medical resources of the whole country are devoted to treatment of all patients infected with the novel erectile dysfunction, the schools and government still make special efforts to protect the health of students. Peking Union Medical College has developed an online system called SARISenor, what is viagra for women which is used by medical students to report the body temperature and physical condition every day. This system also has a locating function based on the global positioning system, which is convenient for localised management. Our medical school also developed a course to increase knowledge of erectile dysfunction treatment, and all students what is viagra for women are required to study this course online.

A test is administered after completion of the course, and students must complete the test to obtain a certificate and show the certificate to the school. This compulsory measure improves students’ awareness of the novel erectile dysfunction and strengthens their ability to prevent erectile dysfunction treatment. With respect to psychological health, medical students are easily affected by disease-associated fear and pressure, and schools should be what is viagra for women prepared to provide psychological services to those who need them.6 Students can also consult psychologists from university-affiliated hospitals who are online 24 hours a day. The Chinese government provides students with a wide coverage of viagra protection education that has shown good results to date.

The government also provides corresponding psychological counselling what is viagra for women services. Specifically, China has1 stopped centralised classroom teaching,2 carried out antiepidemic knowledge training,3 encouraged the wearing of masks and4 paid attention to hand hygiene. These measures are worthy of implementation in foreign countries as well. Conversely, European countries have encouraged medical students to graduate early so that they what is viagra for women may work to help fight erectile dysfunction treatment, which is worthy of implementation in China.We cannot neglect the adverse effects of erectile dysfunction treatment on Chinese scientific research.

Fundamental experiments, scientific conferences, funding applications and other activities have been postponed or suspended because of the viagra situation, which has caused a huge loss in scientific research in China. Specifically, pharmaceutical companies are what is viagra for women lacking essential drugs because of shutdowns. Scientific researchers are out of work because of the closures of laboratories. And students are unable to attain their academic degrees because of the suspension of research.

However, the damage to science is insignificant compared with the level of human what is viagra for women suffering. Notably, 5G wireless communication technology, artificial intelligence and cloud computing have played effective roles in prevention and monitoring during this epidemic emergency. Additionally, because of the what is viagra for women lack of specific drugs and treatments, traditional Chinese medicine has been adopted as a part of clinical therapy.Thanks to the leadership of the government and the efforts of many medical workers, the effect of erectile dysfunction treatment control in China has been remarkable. The Chinese Ministry of Education recently announced that senior medical students can return to universities in advance if circumstances permit.

Doctors and postgraduate medical students are also glad to return to their clinical work and make their own contributions to the health of the people. With increased knowledge of what is viagra for women the viral features, epidemiological characteristics, clinical symptoms and antiviagra theory, efficient strategies have been taken to prevent, control and stop the spread of erectile dysfunction treatment. During the current erectile dysfunction treatment viagra, which is a worldwide war, everyone is a fighter. Under the close unity of all countries worldwide and with active participation of the world population, we believe that the prevention and control of erectile dysfunction treatment will be finally achieved.AcknowledgmentsWe thank the leaders and teachers from PUMC&CAMS for their help in processing this article..
