JAMA is a peer-reviewed medical journal published by the American Medical Association, covering clinical research, reviews, and health policy.
Penn researchers found little tau in the parts of one donated brain where aducanumab had cleared amyloid plaques. The finding comes from one patient, so it fits a lasting protective effect of amyloid removal but cannot establish one.
Reality
Naomi Eisenberger and colleagues report that a 1999 finding of 63 percent higher mortality in strained caregivers has mostly failed to replicate. The correction matters to some 63 million US adults who give care, a role popular wisdom says can shave years off a life.
Reality
Runners died at the Milwaukee and Cardiff half marathons on Oct. 4, 2026, against a JAMA count of 59 deaths in 29.3 million US race finishes. That is about one per 500,000 finishes, and the advice attached is to stop for chest pain or faintness even with the finish in sight.
Reality
The JAMA Perspective says human review can degrade quality once a system beats unaided doctors. The cited evidence is almost entirely simulated, and none of it tests physician-plus-AI.
Reality
US measles cases reached 3,471 by Sept. 17, about 52% more than in all of 2025, CDC figures show. New AAP guidance prepares clinicians for babies infected before birth, whose risk estimates rest on limited research.
Reality
Writing in STAT, a communications consultant compares September's flu, Covid and RSV safety review with the 1955 polio announcement and concludes the movement forgot how to celebrate, on the strength of two episodes and no comparison group.
Reality
Scientists affiliated with the program set out in JAMA what 25 years of monitoring has taught them about multimorbidity in the 9/11 cohort. Their strongest survival number rests on an unmatched comparison.
Reality
With the reconstituted ACIP tied up in court, groups speaking for pediatricians, family physicians and obstetricians reviewed the flu, Covid and RSV evidence themselves, and landed close to where the old federal process did.
Reality
The JAMA argument for replacing physicians rests on single-task simulations. Ohio State's January survey put public openness to AI in healthcare at 42%. That is the number any rollout plan has to clear.
Reality
Their JAMA review reads two years of literature and puts autonomous AI ahead of physician-AI hybrids by 2030, while the AMA's chief executive says some of those studies are simulations that do not all point that way.
Reality
Two August analyses of the same cohort found calcium scores only change predictions at borderline and intermediate PREVENT risk. CTs ordered for other reasons did the job as well.
Reality
Orforglipron's approval takes peptide manufacturing and refrigeration off the constraint list. What replaces them is prescribing capacity in primary care and daily adherence.
