NEJM This Week — June 18, 2026

This week, we discuss endovascular therapy for post-thrombotic syndrome, new evidence on prehospital blood transfusion strategies in trauma patients, and a trial of cefazolin for Staph. aureus bacteremia. We examine evolving approaches to thyroid cancer and share a case of a man with pancytopenia after heart transplantation. Perspectives explore psychedelic therapy, the convergence of Down syndrome and Alzheimer’s disease, and treating addiction.
