NEJM This Week — February 12, 2026

This week includes studies on promising new therapies for IgA nephropathy, evolving antithrombotic strategies after coronary stenting, and the inciting antigen in rare vaccine-related clotting syndromes. We review the urgent challenge of mucormycosis and follow the case of a young woman with headaches and hypertension. We discuss human-subjects research. Perspectives examine rural health, data interoperability, drug labels in the courts, and a pediatrician’s dilemma.
