We investigated the associations of ongoing, chronic stress exposure and stress appraisal on vascular endothelial function (VEF) in young adults. In 72 healthy young adults (74% female; age = 25±1 y), we assessed chronic stress exposure and appraisal with a measure that quantified chronic stress exposure and chronic stress appraisal related to 8 specific stressors over the last year. Participants completed the perceived stress scale (PSS) as a measure of global, proximal stress appraisal.

We examined the effect of habitual pre-exercise caffeine supplementation on training-induced adaptations to exercising systolic (SBP), diastolic (DBP), pulse pressure (PP), heart rate (HR), and double product (DP). Young women (mean±SD; 24±7 y) were randomized to a caffeine (120 mg) supplement (CAF; n=17) or placebo (PLA; n=16) group, completed 6-weeks of high intensity exercise training on three non-consecutive days per week, and supplemented with CAF or PLA 30-60 minutes before exercise or else upon waking. Before (PRE) and after (POST) the intervention, SBP, DBP, and HR were measured, and PP and DP calculated, at rest and during fixed-power exercise at 50W and 75W.

In this case report, we present a 24-year-old woman with a previous diagnosis of epilepsy who was admitted to the hospital following loss of consciousness (LOC). It was initially assumed that this was an epileptic seizure based on her previous diagnosis of epilepsy; however, a review of her electrocardiograms (ECGs) revealed a prolonged QT interval. She was admitted to the cardiology ward for continuous ECG monitoring and subsequently developed self-limiting torsades de pointes (TDP).

Importance: The Accreditation Council for Graduate Medical Education (ACGME) has aimed to increase diversity among the physician workforce. Prospective applicants utilize websites to identify programs that share a commitment to equity and inclusion. Published statements of Diversity, Equity, and Inclusion (DEI) demonstrate a fellowship program's recognition of the importance of improving diversity in health care and medical education.

Article Synopsis
  • Triple-negative breast cancer (TNBC) is a highly aggressive subtype with varied characteristics, limited treatment choices, and poor clinical outcomes, particularly when associated with homologous recombination deficiency (HRD).
  • The study analyzed TNBC tumors from two groups (n=32 and n=58), revealing significant differences in genome-wide copy number and methylation alterations linked to HRD, including lower methylation in specific genomic regions.
  • Findings indicate that HRD in TNBC is associated with key biological pathways, and using machine learning can aid in classifying tumors based on HRD and methylation patterns, offering potential for improved treatment strategies.
