Medicine trains clinicians in a particular silence. Through diagnosis, we medicalize the causes of suffering—contusion, laceration, hemorrhage—as though renaming anguish might contain it, keeping it from spilling out of charts and into our own lives. Operating room and ward become, ironically, fluent in the language…

This study examines whether emerging drug and diagnostic resistance variants are contributing to Ethiopia’s malaria resurgence.
To the Editor Dr Renú and colleagues reported that adjunctive intra-arterial alteplase after successful thrombectomy “may improve functional recovery” in large vessel occlusion stroke. The randomized clinical trial provides an important test of a plausible reperfusion strategy, but the report leaves a key issue unresolved—the…
In Reply As described in the original report, the primary outcome was amended at month 12 to improve clinical relevance and interpretability, considering emerging randomized evidence and the established use of the blinded mRS score assessment. The amendment was implemented on February 10, 2025, after…
To the Editor I appreciate the expanded women’s health learning opportunities provided by the JAMA Network journals under the editorial leadership of Linda Brubaker, MD, MS. The comprehensive Review of prepregnancy care and counseling by Dr Cooper and colleagues will be a valuable resource for…
To the Editor In reading the otherwise comprehensive article by Dr Cooper and colleagues on prepregnancy care and counseling, we were surprised by the lack of discussion about testing for iron deficiency. Iron deficiency, the world’s most common micronutrient deficiency, is epidemic in young women…

To the Editor Dr Patel and colleagues reported that the national launch of the 988 Suicide and Crisis Lifeline was associated with an 11% reduction in adolescent and young adult suicide deaths (4372 fewer than expected). These findings suggest that a phone-based open-access crisis service…
To the Editor Dr Patel and colleagues’ recent article provided promising evidence that the 988 Suicide and Crisis Lifeline has been successful at preventing suicide death. Indeed, their results comparing “high-uptake” and “low-uptake” states are consistent with a time-series analysis of pre–988 Lifeline data that…
In Reply We thank Dr Herring and Dr Purtle for their thoughtful comments. Our study found that suicide mortality among adolescents and young adults decreased after the national launch of the 988 Lifeline, that declines were largest in states where the 988 Lifeline uptake increased…
Prostate cancer has long served as a fertile ground for innovation in cancer therapy. Compared with many other malignancies, localized prostate cancer occupies a unique clinical space. Although the incidence of new diagnoses is high, prostate cancer often follows an indolent natural history, resulting in…
This randomized clinical trial assesses whether stereotactic body radiotherapy is superior to moderately hypofractionated intensity-modulated radiation therapy in terms of patient-reported urinary irritative/obstructive and bowel quality of life and disease-free survival in patients with localized intermediate-risk prostate cancer.
The objective of this study was to assess whether stereotactic body radiotherapy (SBRT) was superior to moderately hypofractionated intensity-modulated radiation therapy (MH-IMRT) for urinary and bowel quality of life and disease-free survival in patients with localized intermediate-risk prostate cancer.
This randomized trial assesses the effect of use of total intravenous anesthesia on days alive and at home 30 days after surgery among older adults undergoing major noncardiac surgery.
