NEJM This Week — January 8, 2026

This week, we explore new options in cardiovascular prevention, fish-oil supplementation in dialysis patients, RSV vaccination, and cutting-edge cellular therapy for leukemia. We discuss advances in lung cancer treatment, approaches to functional dyspepsia, and a complex case of severe infection after travel. Perspectives examine access to and cost of weight-loss drugs, the promise and risks of AI in clinical care, and what it means to care for others while carrying personal loss.
