Working shifts may change more than your sleep schedule

A cross-sectional analysis of 1,814 Japanese workers found that shift work was associated with lower raw seafood intake and shorter sleep patterns in both sexes, while female shift workers also consumed less milk and dairy products. Total energy intake was similar between work groups, but male shift workers were more likely to consider preference and convenience when choosing foods, highlighting potentially important differences in dietary quality and lifestyle rather than calorie intake.

Elusive stem cells offer clues to treat lumbar spinal stenosis

Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the stem cells—unspecialized cells that can develop into specific cell types—that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.

Autoimmune diseases form distinct genetic clusters, study finds

Different autoimmune diseases often share genetic risk factors, but not through a single common genetic vulnerability.

Physics-informed AI framework improves aortic aneurysm stress prediction

Ascending thoracic aortic aneurysms often progress silently, but once dissection or rupture occurs, they can cause severe mortality before hospital arrival or during admission.

Some fertility treatments may raise Kawasaki disease risk in children

A large-scale study in Japan, led by researchers from the University of Osaka and the Osaka Women's and Children's Hospital, has found that certain fertility treatments are associated with an increased risk of Kawasaki disease before age five, although the association differed by treatment type.

High-dose folic acid appears safe from formaldehyde toxicity

Folic acid – an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders – does not elevate toxic formaldehyde in the body, according to a new Cornell University study on mice and human cancer patients who consumed high doses.

Shared biological pathways may explain chronic fatigue across diseases

A shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD has been discovered by researchers at the University of East Anglia and Oxford BioDynamics.

Two scientists win Horwitz Prize for Rett syndrome breakthrough

Columbia University will award the 2026 Louisa Gross Horwitz Prize to Adrian Bird and Huda Zoghbi for their pioneering work on epigenetic regulation in the nervous system and its role in human neurological disease, particularly Rett syndrome.

Genetic marker links popular seizure drug to life-threatening reaction

A genetic marker already used to flag risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine - and it is missing from the gene panels clinicians order before prescribing the drug, Vanderbilt Health-led researchers report Sept. 2 in JAMA Network Open.

Researchers discover dozens of genes tied to OCD and tic disorders

A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk for obsessive-compulsive disorder (OCD) and chronic tic disorders – providing what two researchers said is the most detailed biological understanding of how these conditions develop – and how they might eventually be treated.

Study uncovers cause of abnormal breathing in Rett syndrome

Hyperventilating. Breath holding until they turn blue. This abnormal breathing is frequent and disturbing in people with Rett syndrome, a rare genetic disease.

Coronary angiography can be safely delayed after out-of-hospital cardiac arrest without ST elevation

Immediate coronary angiography did not improve 30-day survival compared with a deferred strategy in patients without an ECG ST-elevation after out-of-hospital cardiac arrest.

Breastmilk from cannabis users showed differences, but cannabis may not be the whole story

A narrative review found that maternal cannabis use may be associated with differences in breastmilk fat, protein, lactose, and the immune factor secretory immunoglobulin A, but evidence comes primarily from only two human studies and remains limited and inconsistent. The authors stress that maternal diet, food security, socioeconomic circumstances, and other forms of adversity could confound these associations and should be incorporated into future research.

New BioTAK score accurately identifies Takotsubo syndrome before catheterization

Takotsubo syndrome is an acute heart condition that primarily affects postmenopausal women and is often triggered by severe emotional or physical stress.

Transcatheter tricuspid valve repair lowers mortality and hospitalizations in high-risk patients

Transcatheter tricuspid valve repair significantly improved clinical outcomes in high-risk patients with severe tricuspid regurgitation, according to results presented in a Hot Line session today at ESC Congress 2026 and published simultaneously in the New England Journal of Medicine.

SHASTA trials show substantial triglyceride reductions with plozasiran

Plozasiran significantly reduced triglyceride levels in severe hypertriglyceridemia patients, showing promise in preventing acute pancreatitis after one year.

Experts call for safer weight loss as concerns grow over GLP-1 use

An editorial in Diabetology International argues that inappropriate GLP-1 use should be judged not only by regulatory compliance or off-label prescribing, but also by whether weight reduction is medically safe, nutritionally adequate, and properly supervised. Drawing on Japanese reports of ketosis and ketoacidosis following inappropriate tirzepatide use, the authors call for greater attention to the risks of unsafe weight-loss practices alongside medication-related harms.

Trial shows antiplatelet therapy needs personalization after stent implantation

Antiplatelet monotherapy reduced bleeding but dual therapy provided greater cardiovascular event protection in patients at high ischemic risk who had undergone stent implantation 12 months earlier.
