Study examines the link between blood type and cardiovascular risk in hemodialysis patients

Do you know your blood type? It is important information that is used for blood transfusions, but few realize blood types could also be linked to disease risks. In the general population, people with blood type O have been reported to have a lower risk of cardiovascular disease and cardiovascular mortality.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

New strategy boosts immune attack against pancreatic cancer

Researchers from the University of Minnesota Medical School have identified why pancreatic cancer is difficult for the immune system to recognize and attack, paving the way for a new approach to improve immunotherapy.

Drinking more water with meals may lead people to eat more

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.

Exercise oncology could unlock new therapeutic pathways against cancer

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.

New tumor organoids strengthen precision oncology research

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.

Specialized blood vessels enable effective immune defense against cancer metastases

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.

Researchers uncover brain target to counter fentanyl-induced slow breathing

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

Spring clock change increases retinal vascular disease risk, study finds

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.

High costs continue limiting insurance coverage for GLP-1 medications

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.

Global road injuries remain major public health challenge, study finds

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.

New target makes cancer cells vulnerable to immune destruction

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.

Stroke patients with disabilities may benefit from thrombectomy treatment

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.

Female doctors request more diagnostic tests in emergency departments

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.

Study reveals geographic gaps in breastfeeding initiation across America

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.

Semaglutide vs. liraglutide: Head-to-head study reveals a diabetes risk difference

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.

Beetroot juice shows its clearest aerobic benefits in recreational exercisers

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.
