In two randomized crossover studies involving 86 adults, greater water consumption and more frequent switching between bites and sips were associated with higher food and energy intake during beef chili and chicken tikka masala meals. The exploratory secondary analysis cannot establish causality, but it challenges the assumption that drinking water during a meal necessarily curbs eating.

Regular exercise is associated with improved outcomes for many patients with cancer, yet those with advanced disease may be unable to participate in exercise-based interventions.

Significant advances have been made in the development of patient-derived tumor "organoids" for preclinical research, in two new studies led by Weill Cornell Medicine investigators.

It has long been suspected that endothelial cells, the specialized cells lining the inner walls of blood vessels, play a key role in determining how the body’s immune system responds to tumors.

Fentanyl causes symptoms that can lead to death from overdose. One of these symptoms is slow breathing, which deprives drug users of oxygen.

For the first time, Northwestern Medicine scientists have detailed how the semiannual clock changes impact a person's risk of developing retinal vascular disease, a group of disorders that affect blood vessels in the retina and can lead to vision loss.

People with autoimmune limbic encephalitis experience memory loss associated with damage to their hippocampus.

Severe flooding may contribute to higher mortality rates from opioid use in rural Appalachia, according to a study by researchers at Penn State.

Texas Tech University faculty Peter Keyel and Kai Zhang are teaming up to build foundational knowledge concerning leishmaniasis, a common, but neglected protozoan parasitic disease.

Despite growing evidence that GLP-1 medications improve health and are worth their cost, many insurance plans still limit coverage. University of Mississippi researchers are examining why, and where that leaves patients.

In 2023, nearly 51 million people were injured and 1.34 million died from road injuries, making road injuries one of the leading global causes of premature death and disability, according to a new study published today in The Lancet Public Health.

Researchers at the University of Illinois Chicago have identified a molecular switch that helps determine whether cancer cells remain soft and difficult to destroy or become stiff enough for the immune system to attack.

Patients with moderate-to-severe disabilities before a stroke are frequently excluded from endovascular thrombectomy (EVT), despite representing a substantial proportion of patients with large vessel occlusion stroke.

A new UCLA Health study examining more than 1.5 million emergency department (ED) visits found that female physicians request more imaging and laboratory tests and admit more patients to the hospital than their male counterparts working alongside them.

A nationwide analysis led by a UC Riverside (Calif.) professor provides one of the clearest pictures yet of where mothers are least likely to begin breastfeeding their babies in the United States and what circumstances associate with lower rates.

Researchers compared semaglutide with liraglutide in 57,456 insured adults without recorded diabetes or cardiovascular disease who initiated formulations indicated for chronic weight management. Semaglutide users had a lower risk of incident diabetes, particularly beyond six months of follow-up, but limited cardiovascular events prevented a precise comparison of cardiovascular risk.

A meta-analysis of 38 placebo-controlled trials involving 703 participants found that beetroot juice supplementation was associated with a small improvement in VO2max or VO2peak during aerobic exercise. Benefits were most consistent in recreationally active adults, while evidence in highly trained athletes remained limited and uncertain.

Nationally representative US data show GLP-1RA use rose 230% among adults with diabetes and 643% among those without reported diabetes between 2017 and 2022, largely driven by semaglutide. Mean annual out-of-pocket payments decreased, but mean total annual payments per user increased, raising concerns about long-term affordability.

Gut microbiome-derived metabolites may influence stress-related mental disorders through neural, immune, endocrine, and epigenetic pathways. Evidence is strongest for depression and preclinical models, while larger longitudinal human studies are needed to establish causality and clinical value.

Your intestine completely rebuilds its inner lining every few days—one of the fastest renewal processes in the human body.
