NEJM This Week — September 10, 2026

This week, we feature new research on gene-edited therapies for children with β-thalassemia and sickle cell disease, treatment for membranous nephropathy, coronary revascularization after myocardial infarction, and an outbreak of severe methemoglobinemia. We review treatment decisions in multiple myeloma, follow a case of man with fever and rash, and report on psychedelic drug development. Perspectives address preventive care, AI-assisted translation, barriers to health care access, and the long shadow of Bedlam.
