Heart failure is common in people who have atrial fibrillation detected during screening, according to a presentation today at EHRA 2026 the annual congress of the European Heart Rhythm Association (EHRA), a branch of the European Society of Cardiology (ESC).

Researchers analyzed data from tens of thousands of people who used low-cost mobile breathalyzers to test their blood-alcohol concentration when drinking.

Research indicates that antidepressant use in IBS is linked to a 35% higher risk of all-cause mortality, highlighting safety issues with long-term treatment.

Findings suggest that regular physical activity and adequate sleep may lower dementia risk, emphasizing the need for evidence-based lifestyle guidelines.

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.

As the COVID-19 pandemic upended virtually every aspect of people's lives, one critical question loomed large for millions of low-income and underserved healthcare patients: Would they still be able to see their own doctor?

Researchers found that cigarette smoke extract disrupted the lung cell barrier, increased IL-6 inflammation, and caused DNA damage in Calu-3 cells, while e-cigarette vapor extract showed no significant adverse effects on these measures under the study conditions. The authors caution that these were in vitro findings using liquid extracts and unflavored e-liquid, so they do not directly predict long-term human health outcomes.

A national survey of 145 registered dietitians found wide variation in how the low FODMAP diet’s reintroduction phase is delivered, especially in dosing, timing, sequencing, and follow-up. The findings suggest that clearer, evidence-based protocols could improve consistency while still allowing individualized care.

This Nature Communications review argues that rat hepatitis E virus is an emerging zoonotic cause of hepatitis that is likely underdiagnosed because current tests are limited and awareness remains low. It shows that ratHEV is widespread in urban rodent populations, can infect humans and some other animals, and may spread mainly through indirect environmental exposure rather than direct rodent contact.

In a repeated-measures study of 18 eumenorrheic female athletes, half-squat strength was highest in the late follicular phase and around ovulation, while handgrip strength peaked in the late luteal phase. Psychological measures also shifted across the cycle, with lower vigor and higher fatigue and depression scores in the late luteal phase, supporting more individualized training monitoring.

More than a quarter of people with Type 2 diabetes take GLP-1 receptor agonists, but the popular diabetes drugs might not work as well for people who have certain genetic variants, according to a new study by Stanford Medicine scientists and their collaborators.

A seminal study from researchers at the Icahn School of Medicine at Mount Sinai and their collaborators in the United Kingdom, Belgium, Spain, the Netherlands, and Iceland has uncovered a new genetic cause of neurodevelopmental disorders (NDDs).

Traumatic brain injury (TBI) is a serious issue affecting thousands of people in the U.S. every year. For military service members, the impact is even more profound.

When in life we gain weight can have a significant impact on our health many years later. In a study involving over 600,000 people, researchers at Lund University in Sweden have investigated how changes in weight between the ages of 17 and 60 are linked to the risk of dying from various diseases

New findings from researchers at the Marshall University Joan C. Edwards School of Medicine and The Hebrew University of Jerusalem have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung.

Macrophages, much like Alice of "Alice in Wonderland," recognize and consume tumor cells that display "eat me" surface markers.

Cases of Borna disease virus 1, or BoDV-1, are extremely rare in humans, but in those who develop disease the outcome is severe, almost always resulting in fatal encephalitis or inflammation in the brain.

​Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over the course of a day, creating daily patterns called circadian rhythms.

Breast cancer is the most common form of cancer in women. According to the World Health Organization, in 2022, around 2.3 million women were diagnosed with breast cancer, and the disease caused about 670,000 deaths worldwide.

Researchers at Oregon Health & Science University have uncovered a key reason why immunotherapy has largely failed in pancreatic cancer - and identified a promising strategy to overcome that resistance.
