NEJM This Week — January 15, 2026

This week, we explore new evidence on managing asymptomatic carotid stenosis, restoring vision in advanced macular degeneration, and preventing migraine in children. We discuss innovative cellular therapy for autoimmune disease, review sudden cardiac arrest in athletes, and describe a case of severe systemic infection with vision loss. Perspectives examine global tobacco risks, the future of telehealth payment, Medicare coverage of new technologies, and the things physicians carry.
