A randomized crossover trial of 108 habitual cannabis users found fewer premature atrial contractions on cannabis-use days than abstinence days. The short-term physiologic findings provide mechanistic insight but were not designed to evaluate long-term cardiovascular health outcomes.

Among more than 7,300 Swedish patients with Alzheimer’s disease and atrial fibrillation, NOAC use was associated with slower cognitive decline than warfarin or no anticoagulation. The observational findings did not establish causality but suggest potential differences in long-term cognitive outcomes.

Female mice recovering from a single ketamine exposure demonstrated microglia-driven neuroplasticity through FKBP51 activation, while male mice did not. The findings identify a sex-specific biologic pathway in a preclinical model, and human relevance remains unconfirmed.

U.S. News expanded its 2026-2027 hospital rankings with new regional specialty evaluations in cancer and cardiovascular care while increasing recognition for regional hospitals. Rankings continued to emphasize risk-adjusted mortality, preventable complications, patient experience, and objective outcomes measures.

A genome-wide analysis of more than 2.5 million adults identified 26 genetic regions associated with fibromyalgia risk. The findings support a neurologic biological basis for the condition, though they do not establish causality or create a diagnostic test.

In a 3-year randomized clinical trial, dialectical behavior therapy and schema therapy produced substantial improvements in borderline personality disorder severity. No statistically significant differences were observed between treatments on primary or secondary outcomes.
