What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

Independent review reinforces value of vaccines across all ages

The Gerontological Society of America (GSA) supports the 2026-27 respiratory season vaccine evidence review released on September 2, 2026, by the Vaccine Integrity Project (VIP) in collaboration with the American Medical Association.

MXene-based hydrogel offers dual-action treatment for periodontitis

Periodontitis is a highly prevalent chronic inflammatory disease worldwide. It leads to periodontal tissue destruction, alveolar bone resorption, and ultimately tooth loosening and loss, severely impacting patients' oral function and quality of life.

Researchers find greater microplastic burden in lung cancer patients

People with lung cancer are more likely to have microplastics in their lungs and to have larger quantities of microplastics in their lungs, according to research that will be presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.

Daily steps may match aerobic training for asthma control

For people with moderate to severe asthma, increasing the number of daily steps may be as effective as structured aerobic training sessions for managing the disease.

Bacterial protein fragment corisin found to drive pulmonary fibrosis

A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell's quality-control system, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found in a new study.

Multiple sclerosis treatment approach developed at Mainz University moves toward clinical application

A therapeutic approach pioneered in Mainz for the treatment of multiple sclerosis (MS) is taking an important step toward clinical application.

GLP-1 drugs have benefits beyond weight loss. Could microdoses preserve them?

A narrative review suggests GLP-1-based therapies deliver metabolic, cardiovascular, renal, and other systemic benefits, raising interest in whether lower fractional doses could improve tolerability and treatment continuity. However, direct evidence for GLP-1 microdosing remains extremely limited, and researchers say prospective studies are needed to determine whether lower doses preserve long-term benefits.

Semaglutide did more than cut weight in this analysis of 6,239 adults

A systematic review and meta-analysis of nine randomized controlled trials involving 6,239 adults with overweight or obesity without diabetes found that subcutaneous semaglutide produced substantially greater reductions in body weight, waist circumference, and C-reactive protein than placebo. The higher dose of 7.2 mg semaglutide showed potential for greater weight loss, although the evidence is largely based on a single trial and requires confirmation.

Newly discovered lung immune cells could transform future flu vaccine design

Influenza continues to cause major illness each year in the United States, leading to more than 35,000 deaths annually. Children, older adults, pregnant individuals, people with weakened immune systems, and those with chronic conditions such as heart disease, metabolic disorders, and cancer are especially vulnerable.

The US switch in shingles vaccines revealed an unexpected heart health pattern

In a natural experiment involving 72,920 propensity-matched US adults aged 60 years and older, recombinant shingles vaccination was associated with a 9% lower cardiovascular disease burden over seven years compared with the live attenuated vaccine. Lower burdens of ischemic heart disease and heart failure were seen in both sexes, while ischemic stroke was significantly lower only among men, supporting further clinical trials and mechanistic studies

Researchers tested dozens of clues for long COVID. One finding stood out

A nationwide study of 218 people in the Faroe Islands examined clinical, neurological, and blood-based markers associated with persistent symptoms around six months after SARS-CoV-2 infection. Despite extensive testing, researchers found no convincing biomarker for long COVID, while a statistical association with lower INR remained within the normal clinical range and requires replication.

Overuse of short-acting bronchodilator linked to increased risk of cardiovascular diseases and death

Overuse of reliever inhalers is associated with higher risks of developing and dying from cardiovascular disease, including heart failure, heart attack and ischemic stroke, in asthma and COPD patients, according to a study published today in ERJ Open Research.
