LVIS stent-assisted coiling effectively treats wide-necked intracranial aneurysms

Intracranial aneurysms are weakened, bulging areas of cerebral arteries that can rupture, causing subarachnoid hemorrhage and, in turn, significant disability or death.

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.

Rising marine heatwaves create growing challenges for human health

The devastating impacts of marine heatwaves extend far beyond dying coral reefs and declining fisheries, with new research warning these extreme ocean warming events are posing a growing threat to humans' physical and mental health.

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.

Tirzepatide lowers heart attack and cardiovascular event risk in adults with type 2 diabetes

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.

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.

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?

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.

Firearm injury patients face measurable risk of bacterial infections

A new study from researchers at the University of Maryland School of Medicine (UMSOM) found that bacterial infections develop in approximately 5 percent of adults hospitalized with firearm injuries, with most infections occurring during the initial hospitalization rather than after patients return home.

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.

AI sleep model reveals health risks missed by standard apnea scores

An AI foundation model extracted hidden physiological patterns from routine polysomnography and identified five patient groups with distinct long-term risks of mortality, cardiovascular disease, and neurological disorders. The approach outperformed apnea–hypopnea index severity categories for risk stratification and remained informative in an independent sleep cohort.

NEWS2 score may improve antibiotic decisions in suspected sepsis

A study of nearly 100,000 adults treated for suspected infection suggests that the National Early Warning Score (NEWS2), a score based on routinely collected vital signs that is widely used to identify patients at risk of clinical deterioration, may help clinicians identify which patients are most likely to benefit from immediate antibiotic treatment and which may safely undergo further evaluation before receiving antibiotics.

Healthy midlife habits linked to longer dementia-free years

Having normal blood pressure, no diabetes, and not smoking from age 48 to 68, are associated with nearly 13 additional years on average of dementia-free life, a new study shows.

GLP-1 drug tirzepatide associated with lower risk of major cardiovascular events

Adding the GLP-1 receptor agonist drug tirzepatide (marketed as Mounjaro) to standard care for patients with type 2 diabetes and heart disease is associated with a lower risk of a major cardiovascular event, such as a heart attack or stroke, finds a study published by The BMJ today.

NIH funds Boston University center for Alzheimer's prevention studies

Maria Glymour, Andrew Stokes, and Deborah Carr will lead the Boston University-Quantitative Population Science and Healthy Cognitive Aging Research Program (BU-SHARP) to foster national research collaboration on preventing and ameliorating the consequences of Alzheimer's disease and related dementias in disproportionately affected populations.

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.

Neuroscience-informed therapy provides massive cost-savings for opioid addiction treatment

A new economic evaluation from the University of California San Diego School of Medicine has revealed that Mindfulness-Oriented Recovery Enhancement (MORE) - an innovative, evidence-based, neuroscience-informed therapy for opioid misuse and chronic pain - provides $12 in cost savings for every dollar spent, between two and six times more cost effective than other addiction treatments such as residential or intensive outpatient treatment.

The healthiest super-agers may have one thing in common: stable cognition

A 10-year study of 1,003 older adults linked cognitive super-aging to fewer emergency visits, unplanned hospital admissions, delirium episodes, dementia diagnoses, and residential aged care placements. Maintaining cognitive performance over time showed the strongest overall association with favorable health outcomes and was linked to a 46% lower mortality risk.

New study advances understanding of dementia after age 90

It may seem natural to assume that people experience cognitive decline after age 90, but until recently, researchers had limited evidence about how advanced age affects the brain.
