Biomarker subpopulations have become increasingly important for drug development in targeted therapies. The use of biomarkers has the potential to facilitate more effective outcomes by guiding patient selection appropriately, thus enhancing the benefit-risk profile and improving trial power. Studying a broad population simultaneously with a more targeted one allows the trial to determine the population for which a treatment is effective and allows a goal of making approved regulatory labeling as inclusive as is appropriate. We examine new methods accounting for the complete correlation structure in group sequential designs with hypotheses in nested subgroups. The designs provide full control of family-wise Type I error rate. This extension of previous methods accounting for either group sequential design or correlation between subgroups improves efficiency (power or sample size) over a typical Bonferroni approach for testing nested populations.
The purpose of this study was to examine whether the latest National Institute for Health and Care Excellence proton pump inhibitor (PPI) guidelines changed physician prescribing patterns in clinical practice.

Using data from the United Kingdom Clinical Practice Research Datalink, we calculated monthly PPI prescribing rates in adults by dividing the number of PPI prescriptions by the number of patients in each calendar month. Using these rates, we conducted an interrupted time-series analysis to compare PPI prescription rates before (September 2010-August 2014) and after (September 2014-August 2018) guideline publication, estimating a slope and level change using segmented autoregression.

In the preguideline period, monthly PPI prescription rate increased by 46.9 (95% confidence interval (CI) 40.8 to 53.0) prescriptions per 100,000 persons. Following guideline publication, there was no immediate change in the monthly PPI prescribing rate (137.6, 95% CI -36.7 to 311.9 prescriptions per 100,000 persons), but there was a modest attenuation of the change in monthly rate (-23.9, 95% CI -14.0 to -33.6 prescriptions per 100,000 persons). However, the predicted rates mirror the observed rates after guideline publication, suggesting limited changes.

Despite efforts to minimize the overprescribing of PPIs, there was little meaningful change in clinical practice following the 2014 National Institute for Health and Care Excellence recommendations.

Veterans represent a significant proportion of the U.S. population (7%), and the impact of the coronavirus disease 2019 (COVID-19) in this group of vulnerable patients has been largely overlooked. This analysis reports COVID-19 patient demographics, infection, mortality, and case-fatality rates in the veteran population.

This is a cross-sectional analysis using the Veterans Affairs informatics and computing infrastructure tool to assess the veterans' COVID-19 infections at the Veterans Affairs facilities from March 4th to June 23rd, 2020.

Of the 10,621,580 veterans in this analysis, 59.7% were ≥65 yo, 92.5% were men, 68.7% were white, and 14.2% were black. Veterans ≥65 yo comprised 52.1% of cases and 89.9% of deaths. The relative mortality and case-fatality rates of black veterans, when compared with white veterans, were 2.83 (CI 2.56-3.14; P<.001) and 0.75 (CI 0.68-0.82; P<.001), respectively. Among the veterans who died from COVID-19, 87.4% had a history of cardiovascular disease, 56.5% had a history of diabetes, and 33.6% were obese.

Elderly veterans (≥65yo) and veterans with a history of cardiovascular disease represent a large proportion of the VA COVID-19 cases and deaths. Black veterans had higher mortality rates but lower case fatality rates when than white veterans.

Urinary albumin-to-creatinine ratio (UACR) is one of the important diagnostic markers of chronic kidney disease. We aimed to investigate the association between UACR within normal range and cardiovascular or all-cause mortality.

This study included a nationally representative sample of 31,413 U.S. adults aged greater than or equal to 20years enrolled in the National Health and Nutrition Examination Survey 1999-2014. Mortality was ascertained through 2015. We used multivariable Cox proportional models to investigate the association of UACR with all-cause and cardiovascular mortality. read more Stratum-specific analyses were conducted by age, sex, race, education status, and comorbidities (e.g., hypertension, diabetes, cardiovascular disease, and chronic kidney disease).

Over a median follow-up of 7.6years, 2854 all-cause deaths and 454 cardiovascular deaths were identified. Higher UACR (per 10mg/g) was associated with increased risk of all-cause mortality (adjusted hazard ratio= 1.29, 95% confidence interval= 1.22-1.37) and cardiovascular mortality (adjusted hazard ratio= 1.34, 95% confidence interval= 1.17-1.55). The association was larger among women for both all-cause and cardiovascular mortality, and among younger and highly educated participants only for all-cause mortality. The association did not differ by the presence of comorbidities.

Elevated UACR within normal range was associated with higher all-cause and cardiovascular mortality risk across almost all subgroups including participants without comorbidities. Our findings suggest the importance of the early detection of albuminuria and careful evaluation of UACR even within normal range to reduce mortality risk.
