NEJM This Week — September 3, 2026

This week, we feature new research on acute myeloid leukemia, achondroplasia, pediatric septic shock, and RAS-mutant lung cancer. We also review the evaluation and management of pulmonary nodules and follow a diagnostic case of recurrent fractures. Perspectives explore reproductive health care, the human–animal bond in health care access, and on creating space for patients’ voices in clinical decision making.
