The goal in selecting these recent articles was to help identify literature that may change the clinical practice of women's health for internists. Articles were identified by reviewing the high-impact medical and women's health journals, national guidelines, ACP JournalWise, and NEJM Journal Watch. Cardiovascular (CV) disease remains the leading cause of death in women. The emphasis of this review is on identifying opportunities for CV risk reduction to prevent disease and on early identification of women with preexisting atherosclerotic disease to allow for early initiation of medical treatment...

BACKGROUND: Germline DNA damage repair gene mutation (gDDRm) is found in >10% of metastatic prostate cancer (mPC). Their prognostic and predictive impact relating to standard therapies is unclear. OBJECTIVE: To determine whether gDDRm status impacts benefit from established therapies in mPC. DESIGN, SETTING, AND PARTICIPANTS: This is a retrospective, international, observational study. Medical records were reviewed for 390 mPC patients with known gDDRm status...

OBJECTIVE: We have proposed that three scientific criteria are important to the ethical justification of RCTs: (1) they should be designed around a clear hypothesis; (2) uncertainty should exist around that hypothesis; (3) that uncertainty should be as established through a systematic review. We hypothesized that the majority of a sample of recently-published RCTs would not explicitly incorporate these criteria, therefore rendering them potentially unjustified on scientific grounds. STUDY DESIGN AND SETTING: Cross-sectional analysis of all RCTs published in the New England Journal of Medicine (NEJM) and the Journal of the American Medical Association (JAMA) in 2015...

Osteoporotic vertebral compression fractures (OVCFs) are a significant cause of morbidity and mortality in the United States and worldwide, with estimates of 750,000 to 1.5 million occurring annually. As the elderly population continues to increase, the incidence of OVCFs will continue to rise, as will the morbidity and mortality associated with this condition. Vertebral augmentation (VA) was almost universally accepted as the appropriate treatment modality prior to 2 sham trials published in 2009 by the New England Journal of Medicine (NEJM)...

BACKGROUND AND PURPOSE: We set out to revisit and comment on the evidence surrounding a popular figure published in the New England Journal of Medicine (2002), which suggests that the incidence of immune-mediated diseases, including multiple sclerosis (MS), is increased by reduced exposure to infections. METHODS: Commentary. RESULTS: We found that, to date (May 2017), this influential article has been cited >2000 times. However, on close investigation of the figure, we noticed some problems...

BACKGROUND: Healthcare policy is often determined by well-designed studies most often published in high-impact medical journals. However, concern about the presence of publication bias against lower-extremity arthroplasty-related studies has called into question some of the validity of certain reports. There are only a few studies investigating the presence of the bias in high-impact medical journals against lower-extremity arthroplasty intervention, particularly in the Journal of American Medical Association (JAMA), New England Journal of Medicine (NEJM), and the Lancet...

There has been a disagreement amongst experimentalists and between experimentalists and theoreticians as to the gas-phase structure of dimethyl peroxide. We have investigated this problem with high-level CCSD(T)-F12 and MRCI procedures. There can be no doubt anymore that, at the minimum of the potential energy surface, the COOC fragment has a trans-structure. The dynamical structure of the molecule can, however, be different and be explained by the very slow torsional motion. We have analysed the dynamical structure using numerical wavefunctions of the torsional motion and a fully optimized potential curve of MP2/aug-cc-pVTZ quality...

WHAT IS KNOWN AND OBJECTIVE: Study design and statistical methods have become core components of medical research, and the methodology has become more multifaceted and complicated over time. The study of the comprehensive details and current trends of study design and statistical methods is required to support the future implementation of well-planned clinical studies providing information about evidence-based medicine. Our purpose was to illustrate study design and statistical methods employed in recent medical literature...

REVIEW
Miriam Thake, Andrew Lowry
INTRODUCTION: The unjustified exclusion of older participants from clinical trials creates research populations that are non-representative, in turn creating difficulties applying research to the target populations. The aim of this study was to assess the proportion of randomised control trials (RCTs) that have unexplained upper age limits and review whether this proportion is reducing over time. METHODS: All RCTs in BMJ, Lancet, JAMA and NEJM from 1998 to 2015 were reviewed to identify any specified upper-age cut off and, if so, whether this exclusion criterion had an explanation in the text...

16 Background: Value in healthcare (patient-centered outcomes achieved per dollar spent) unifies performance improvement goals with health outcomes of importance to patients. We describe the process through which value-based measures for breast cancer patients and dynamic capture of these metrics via our new electronic health record (EHR) were developed at our institution. METHODS: A review of the breast cancer literature was conducted on treatment options as well as expected outcomes and potential treatment complications...

Primary aldosteronism (PA) is a heterogeneous group of disorders including both sporadic and familial forms (familial hyperaldosteronism type I, II and III). PA is the most frequent endocrine cause of secondary hypertension and associated with a higher rate of cardiovascular complications, compared with essential hypertension.Here I review the recent progress in understanding of the genetic and molecular mechanisms leading to autonomous aldosterone production in PA.Systematic screening detects primary aldosteronism in 5 to 10% of all patients with hypertension and in approximately 20% of patients with resistant hypertension...

PURPOSE: Missing data are a major problem in the analysis of data from randomised trials affecting power and potentially producing biased treatment effects. Specifically focussing on quality of life outcomes, we aimed to report the amount of missing data, whether imputation was used and what methods and was the missing mechanism discussed from four leading medical journals and compare the picture to our previous review nearly a decade ago. METHODS: A random selection (50 %) of all RCTS published during 2013-2014 in BMJ, JAMA, Lancet and NEJM was obtained...
