#MedNews: Pennsylvania has reported more than 1300 measles cases—the highest number in a single state since 1991—and 6 deaths.
With outbreaks growing across the US amid declining vaccine coverage, could this become the new normal?

Thirty years ago, JAMA published the first #CONSORT Statement, the reporting guideline and checklist that helped establish the standard for high-quality, transparent reporting of randomized clinical trials.
For three decades, CONSORT has strengthened the integrity of clinical research by helping authors clearly report how trials were conducted and enabling readers to assess whether results can be trusted.
The updated CONSORT 2025 Statement reinforces the durability of these standards while incorporating important advances in scientific reporting, including open science.

💬 Viewpoint by @JAMAHealthForum Editorial Fellow Sugy Choi, PhD, Jonathan Cantor, PhD, Elizabeth Fitelson, MD, and
Catherine Monk, PhD:
Improving #MaternalMentalHealth requires more than screening for depression and anxiety. Building an effective care system for postpartum psychosis and other perinatal mental illnesses requires integrated care models, rapid psychiatric consultation, and treatment pathways that are timely, coordinated, and financially accessible.

💡 JAMA Insights: #AcuteVestibularSyndrome can result from peripheral vestibular pathology or a central nervous system cause, and stroke accounts for 10% to 25% of cases.
Physical examination findings including nystagmus pattern, skew deviation, the head impulse test, the general neurological examination, and gait can help distinguish peripheral from central causes and guide decisions about imaging or neurology consultation.

💬 Editorial by Arthur Chang, MD, MS, Carol Iddins, MD, and JAMA Senior Statistical Editor Roger Lewis, MD, PhD: Medical countermeasures for internal #Radionuclide contamination remain limited, and currently approved options for some exposures require intravenous injection or nebulization under medical supervision.
An oral countermeasure such as #HOPO141 may improve emergency deployment and strengthen public health preparedness in mass radiological incidents.
ja.ma/4BUoGjw
📣 Preliminary Communication: An oral #ActinideChelator, HOPO 14-1, was administered as a single dose in healthy adults without serious adverse events or dose-limiting toxic effects in this phase 1 #clinical trial.
The findings indicate rapid absorption and primarily fecal elimination, supporting continued development of an oral countermeasure for internal radionuclide and heavy metal contamination with potential relevance for public health preparedness.
ja.ma/4AtHiFK
💬 Viewpoint by Jesse Burk-Rafel, MD, MRes, and Robert Wachter, MD: In the era of #AI in #medicine, #physician training may need to emphasize bedside clinical skills, management reasoning, and critical appraisal rather than encyclopedic recall alone.
The proposed educational impact is a longitudinal approach to training physicians to work effectively with and without #AI.

💬 Viewpoint: Lisa VanWagner, MD, MSc, John Bucuvalas, MD, David Goldberg, MD, MPH, and Ali Zarrinpar, MD, PhD: As organ supply expands in #Transplantation through donation after circulatory death, #MachinePerfusion, and other emerging approaches, inequities may shift from waitlist allocation to referral, evaluation, and listing.
Equity should be assessed across the full transplant care continuum, consistent with the Organ Procurement and Transplantation Network Modernization Initiative.
ja.ma/4kJntFz
💬 Viewpoint by JAMA Deputy Editor Linda Brubaker, MD, MS, and Executive Editor Gregory Curfman, MD: Recent federal changes affecting J-1 visas, graduate student loan limits, and #MedEd admissions investigations may disrupt efforts to build a #physician workforce that is sufficient and representative of the US population.
These pressures could affect access to training, workforce diversity, and care delivery in underserved communities.

💬 Editorial by Jeffrey L. Saver, MD: In #AcuteIschemicStroke, reperfusion therapies now reopen most occluded arteries, but many patients still have disabling outcomes after treatment.
The LAIS trial indicates that loberamisal may improve 3-month disability-free recovery in patients who were not eligible for endovascular thrombectomy, supporting continued evaluation of #Neuroprotection alongside reperfusion strategies.

A new #HeartTransplant allocation score, the US Candidate Risk Score, demonstrated better discrimination of 6-week mortality among adult US transplant candidates than the current 6-status system.
In match-run simulations, reordering candidates by this score prioritized patients with higher observed mortality without transplant while not increasing donor-candidate distance.
This finding supports use of more objective medical urgency criteria in US donor heart allocation policy.

A cross-sectional analysis of active-duty US Army men indicates that routine #Testosterone screening would identify many service members with a single morning testosterone concentration below commonly used thresholds.
Following the recent US government memorandum requiring annual screening for active-duty and reserve military personnel aged ≥30 years, these findings suggest that confirmatory testing and clinical evaluation will be common.

US #MedicalSchools expanded from 125 schools in 2005-2006 to 158 in 2025-2026, with more schools enrolling 700 or more students. Total first-year enrollment also increased over the 20-year period.
In 2025-2026, women outnumbered men in first-year enrollment, total enrollment, and graduates at MD-granting schools. Entering students from the same state as the medical school continued to represent most first-year students, although the in-state share was lower than in 2005-2006.

Most schools reported a 1½-year preclerkship phase in 2025-2026, and pass-fail only grading became more common in preclerkship courses and clerkships. These findings inform planning for physician training capacity and medical school curriculum design.

A study in JAMA of more than 5 million US births indicates that more infants are not receiving intramuscular #VitaminK at birth, despite its routine use to prevent vitamin K deficiency bleeding. Nonreceipt of intramuscular #VitaminK at birth increased from about 3% in 2017 to nearly 7% in 2025. The study found higher risks of bleeding, intracranial (within the brain or skull) bleeding, and death with a bleeding diagnosis among infants who did not receive vitamin K, consistent with findings from a separate study in Sweden published in JAMA Pediatrics. These data support the public health importance of maintaining vitamin K prophylaxis at birth.
