Leisure-time exercise linked to lower dementia risk

For years, scientists have known that regular physical activity can help lower the risk of dementia. But new USC research suggests that it's not only the amount but also the activity's context - for work or for leisure - that makes a difference.

Wearable ultrasound patch tracks critical central venous pressure

The patch probe, with a center frequency of 8.5 MHz, provides excellent spatial resolution and penetration depth.

Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

A four-week spice experiment challenges expectations about post-meal benefits

Culinary doses of herbs and spices did not significantly alter postprandial endothelial function, glycemia, or lipemia after four weeks of corresponding spice-containing diets in adults at cardiometabolic risk. The findings suggest that acute spice-related effects may be less apparent with longer-term exposure, although the study may have been underpowered to detect modest benefits.

Laser treatment may extend survival in glioblastoma patients

For patients facing a diagnosis of glioblastoma - one of the most aggressive and devastating forms of brain cancer - the standard path forward has long meant an invasive open-skull surgery and a daunting prognosis.

New microfluidic chip predicts personalized glioblastoma treatment responses

Even for the same brain tumor treated with the same anticancer drug, the effect can differ from patient to patient.

Why keto appears to lower blood pressure for some people but not others

A narrative review finds that ketogenic diets may modestly lower blood pressure through weight loss, reduced visceral fat, improved insulin sensitivity, fluid and electrolyte shifts, and anti-inflammatory effects. However, effects vary across studies, long-term cardiovascular evidence remains limited, and diet quality, hydration, electrolyte balance, and medication monitoring are important.

Würzburg researchers discover alternative approach to preventing thrombosis

Glycoprotein VI, or GPVI for short, is a surface receptor found exclusively on platelets and their precursor cells, megakaryocytes in the bone marrow.

In a famous Blue Zone, daily movement was tied to fewer memory complaints

Older adults in Sardinian Blue Zone communities who took more daily steps, spent less time sedentary, perceived their physical health more positively, and had greater confidence in their memory reported fewer memory complaints. Sleep efficiency was not significantly associated with memory complaints, and the cross-sectional study cannot establish cause and effect.

Dysregulated immune cells drive hidden inflammation after heart attacks

People with narrowing of the coronary arteries have low-grade, uncontrolled inflammation in the body, even if they are symptom-free and receiving optimal treatment.

Huge philanthropic grant funds pioneering stem cell-based heart attack therapy

In a landmark moment for both the treatment of heart disease and philanthropic support, The Marcus Foundation has awarded the head of USC Stem Cell Center, Chuck Murry, MD, PhD, $28.7 million to advance a clinical trial testing a stem cell-based therapy designed to regenerate damaged tissue after a heart attack.

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.

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.

Scientific statement reframes cardiovascular care for older patients with cognitive impairment and frailty

Older adults with cardiovascular disease (CVD) often have coexisting cognitive impairment and frailty, conditions that can significantly affect treatment decisions, recovery, independence and quality of life and should be considered as part of an aging-informed approach to care, according to a new American College of Cardiology Scientific Statement published in JACC, the flagship journal of the ACC.

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.

Metabolic stress triggers long-lasting immune system changes in diabetes patients

A growing understanding of trained immunity, a form of long-lasting immune system adaptation, is reshaping how scientists view diabetes and its many complications.

Severe COVID-19 reactivates dormant viruses and may leave a lasting viral signature

A longitudinal study of 1,154 hospitalized COVID-19 patients found widespread reactivation of chronic Herpesviridae and Anelloviridae, with distinct viral patterns linked to disease severity, inflammation, and clinical outcomes. Anelloviridae also persisted during convalescence and were associated with physical deficits in long COVID, although the study did not establish causation.

AI detects multiple heart failure types from routine ECGs

A new study led by researchers at Wake Forest University School of Medicine has found that artificial intelligence (AI) can help clinicians identify signs of heart failure, including a type that is often missed in routine care.

Multi-omics research uncovers new therapeutic targets for Fabry disease

A comprehensive review is shedding new light on Fabry disease, a rare inherited disorder that can progressively damage multiple organs and significantly affect quality of life.
