Bright-light therapy may reduce attention lapses during night work

Light therapy may improve alertness and attention/reaction time during simulated night shifts, with the strongest benefits appearing after light exposure. Effects on executive function were smaller and largely limited to treatment, while substantial study heterogeneity and limited real-world evidence warrant caution.

One cognitive ability stood out in a study of Western diets and Alzheimer’s risk genes

A Western dietary pattern was associated with faster attention decline among older adults carrying the APOE ε4 allele, while no significant cognitive associations emerged for a Prudent dietary pattern. However, the Western diet association lost statistical significance after excluding participants with possible baseline cognitive impairment, making the finding exploratory.

What 38,000 trauma and incident records reveal about e-scooter safety

E-scooter riders admitted with moderate-to-severe trauma showed a distinct injury profile, with proportionally more traumatic brain, vascular, and internal organ injuries than motorcyclists and fewer fractures. Rental-scooter data also linked greater reported injury severity with younger age and female sex, while collision rates varied with area-level deprivation.

Semaglutide slows blood protein signature linked to future dementia risk

A post hoc analysis of 2,970 older SELECT participants found that semaglutide slowed worsening of a 25-protein blood signature that predicts future dementia risk. Over 104 weeks, semaglutide produced larger effects on modeled 5-year than 20-year dementia risk, but whether these biomarker changes translate into less cognitive decline or dementia remains unknown.

Phthalates may contribute to high blood pressure in pregnant women

Phthalates, which are chemicals found in plastics, personal care products and hundreds of other consumer goods, may contribute to high blood pressure in pregnant women, according to a study published in the Journal of the Endocrine Society.

Neighborhood conditions help explain racial disparities in ovarian cancer survival

A new study led by researchers at the University of Pittsburgh found that women living in socially vulnerable communities face a 20% higher risk of death after an ovarian cancer diagnosis compared with women living in less vulnerable communities.

Higher doses of common fertility drug linked to pregnancy risks

Around one in six people experience infertility, with irregular or absent ovulation among the most common causes.

Study links better midlife vascular health to nearly 13 more dementia-free years

A long-term study of 12,409 adults found that a greater burden of diabetes, hypertension, and current smoking in midlife was associated with substantially fewer years lived free of dementia. Adults with none of these risk factors had about 30.1 dementia-free years from age 55, compared with 17.5 years among those with all three, a difference of nearly 13 years.

Simple biological age score flags higher cognitive decline risk in older adults

A study of 4,818 middle-aged and older Chinese adults found that higher light BioAge was associated with greater risks of cognitive impairment, episodic memory decline, and reduced mental intactness. The simple measure, based on age, creatinine, glucose, and CRP, added modest predictive information but requires further validation before clinical use.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Two-gene interaction reveals metastatic risk in breast cancer

Why do some breast cancer patients face a much higher risk of distant metastasis, while others with seemingly similar disease experience far better outcomes?

Rising wildfire smoke in the US offsets improvements in prenatal health

Wildfires are well-known health risks. Now, in a new Frontiers in Environmental Health study, researchers in the US have – for the first time – evaluated how prenatal PM2.5 exposure has changed over space and time on a national scale, and what role wildfires play in shaping these trends.

Living near a dry cleaner may come with an unexpected Parkinson’s disease link

A nationwide case-control study of older U.S. Medicare beneficiaries found that living closer to a dry-cleaning establishment was associated with higher odds of incident Parkinson’s disease, with the strongest association among people living within 0.1 mile.

Fine particle pollution raises rheumatoid arthritis flare risk and disease activity

Higher ambient PM2.5 exposure was associated with increased rheumatoid arthritis disease activity and a greater likelihood of flares in a four-year South Korean cohort of 1,070 patients. The association appeared stronger with sustained exposure over approximately two weeks or longer, while women and nonsmokers showed more pronounced links between PM2.5 and DAS28-CRP.

Air pollution in pregnancy raises birth risks differently across trimesters

A population-based study of 26,582 live singleton births in Madrid found that associations between NO₂ exposure and adverse birth outcomes varied by pregnancy stage, with key patterns emerging in the first and third trimesters.

Nighttime light linked to conflicting signs of biological aging

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.

Digital care app improves quality of life for breast cancer patients

Regularly checking in with patients with metastatic breast cancer by way of an app to enquire about their well-being – and responding promptly – can alleviate their debilitating fatigue and make their daily lives easier.

First-trimester protein intake linked to lower odds of small-for-gestational-age birth

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

Experts call for better trials as IVF preparation techniques show unproven results

Preparation techniques used before embryo transfer, considered the most critical step in the IVF process, show no proven effect on pregnancy rates and remain inconclusive due to limited or low-quality data, a new Cochrane review finds.

Long-acting HIV prevention tools could help close the gap before a vaccine arrives

A review of non-vaccine HIV interventions highlights the strong preventive effects of long-acting PrEP, sustained ART, U=U, vertical transmission programs, and voluntary medical male circumcision. Gene editing and multispecific antibodies may expand future options, but safety, cost, access, adherence, and implementation barriers remain.
