NEJM This Week — November 12, 2026

This week, we feature new research on preventing venous thromboembolism after hip or knee arthroplasty, antiplatelet therapy for acute coronary syndromes, and treatment for IgA nephropathy. We review advances in malaria prevention and follow a case of recurrent cardiomyopathy. Perspectives explore AI surveillance, equity in maternal–fetal medicine, and the challenges and rewards of medical training.
