Children show high exposure to PFAS despite regulatory restrictions

These chemical compounds are highly stable and linger in the environment. Thanks to their water-, oil- and stain-repellent properties, they are widely found in everyday items, such as non-stick pans, waterproof clothing, food containers and fire-fighting foams.

Quality of care shapes how patients experience mental health hospitalization

What makes an admission to a mental health unit a more or less traumatic experience, and what role do nurses play in this experience? A study recently published in the Journal of Clinical Nursing focuses on a question that is as sensitive as it is little explored: the perception of quality of care as a factor that can make a big difference in mental health care.

Mediterranean diet during pregnancy cuts babies’ food allergy risk

Researchers found that mothers who closely followed a Mediterranean diet during pregnancy and breastfeeding had infants with lower odds of developing food allergies. High fruit, vegetable, and full-fat dairy intake appeared protective, while higher poultry, red meat, and fish intake during pregnancy increased risk.

Daily meal timing influences longevity risk in adults, study reveals

Researchers analysing Aging Cell data from over 33,000 US adults found a U-shaped link between daily eating window length and mortality. Eating for 11–12 hours per day was tied to the lowest risk, while very short (<8h) or long (≥15h) windows raised death risk, especially in older and White participants.

Study reveals how centenarians preserve youthful immune defenses

Researchers mapped immune cells from centenarians, their offspring, and younger controls across three cohorts using multi-omics single-cell profiling. They found that centenarians retain leaner helper pools but have enhanced cytotoxic and NK cell programs, along with reinforced NK–T communication networks.
