(Press-News.org) A new analysis of the SELECT trial – the largest and longest clinical trial to date examining the cardiovascular benefits of semaglutide (a medication used to support weight loss and diabetes management) – confirms it also lowers the risk of major heart problems in people who are overweight or obese and already have heart disease, even if they don’t have diabetes. Importantly, this heart protection happens regardless of how much weight a person loses or their baseline body weight, according to the new study, published in The Lancet.
The SELECT trial originally studied over 17,000 adults with heart disease and a body mass index (BMI) of 27 or higher, comparing semaglutide to a placebo. This new analysis looked closely at how patients’ weight and waist size changed during the trial and how those changes related to cardiovascular events such as heart attacks and strokes. Researchers found that while semaglutide helped people lose weight and reduce waist size, the amount of weight lost early on didn’t predict who would have fewer heart problems. However, shrinking waist size—a sign of less belly fat—was linked to better heart outcomes and accounted for about one-third of semaglutide’s overall benefit.
The authors say that these findings indicate that semaglutide can offer important heart benefits that go beyond weight loss, opening the door to new ways of treating and preventing serious heart problems in people with obesity and cardiovascular disease.

‘Weight loss’ drug helps heart regardless of amount of weight lost
2025-10-22
Anti-obesity medication semaglutide may help to prevent heart attacks and other major cardiac events regardless of how much weight people lose while taking the drug, according to a new study led by a UCL researcher.
The finding, the researchers say, suggests there are multiple ways the drug benefits the heart, rather than its protective effect on cardiovascular health being due solely to weight loss.
The study, published in the Lancet journal and funded by Novo Nordisk, looked at data from 17,604 people aged 45 and over who were overweight and had cardiovascular disease, who were randomly assigned either ...
First truly global picture of wide inequalities in care for women’s cancers
2025-10-22
Largest-ever analysis of data on stage, treatment and consistency with international clinical guidelines, from over 275,000 women diagnosed with breast, cervical or ovarian cancer during 2015-2018 in 39 countries
For breast and cervical cancer, 40% of women in high-income countries had their cancer detected at an early stage, compared with below 20% for women in low- and middle-income countries
Ovarian cancer is least likely to be diagnosed early across the world, at less than 20%
Three-quarters (78%) of women in HICs and more than half (56%) of women in LMICs were offered surgery, but international clinical guidelines were not followed ...
International Consortium of Women’s Mental Health Experts present scientific evidence to support classification of postpartum psychosis as a distinct disease
2025-10-22
An international panel of leading experts on women’s mental health is recommending that postpartum psychosis be recognized as a distinct category of mental illness and classified accordingly within standardized medical coding systems.
The recommendation, known as a “consensus statement,” and a comprehensive review of the scientific literature on postpartum psychosis appear in the October 22 issue of Biological Psychiatry. [DOI: /10.1016/j.biopsych.2025.10.016]
Postpartum psychosis is an acute and severe psychiatric illness that sets in within weeks after delivery. ...
PET imaging of inflammation predicts recovery, guides therapy after heart attack
2025-10-22
Reston, VA (October 21, 2025)--A new approach to PET imaging offers a promising way for physicians to promptly identify patients who are at risk for poor functional recovery after a heart attack, according to new research published in The Journal of Nuclear Medicine. By visualizing CXCR4--a cellular protein that plays key role in inflammation--this technique can enable the timely implementation of treatments to mitigate inflammation and prevent heart failure progression.
Heart attack, also known as acute myocardial ...
Pennington Biomedical awarded renewal of NIH-funded Center to Advance Metabolic Disease Research and train future scientists
2025-10-22
Following a competitive review process, the National Institutes of Health (NIH) funding for Pennington Biomedical’s Metabolic Basis of Disease Center of Biomedical Research Excellence (COBRE) was renewed for an additional five years. This Phase II renewal builds on the momentum achieved since the center’s establishment in 2020, enabling continued support for young scientists who are focused on the mechanisms through which nutrition and metabolism contribute to health.
“The renewal of this center grant provides Pennington Biomedical with the opportunity to continue a metabolic ...
Planetary scientists link Jupiter’s birth to Earth’s formation zone
2025-10-22
New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the longest-standing puzzles in planetary science: why many primitive meteorites formed millions of years after the first solid bodies. The study, which combined hydrodynamic models of Jupiter’s growth with simulations of dust evolution and planet formation, was recently published in Science Advances.
Through state-of-the-art computer simulations, planetary scientists André Izidoro and Baibhav Srivastava found that Jupiter’s rapid ...
University of Louisville, UofL Health receive $11.5 million to develop new cancer immunotherapies
2025-10-22
Cancer remains one of the greatest health concerns in the U.S., but University of Louisville cancer researchers and UofL Health – Brown Cancer Center oncologists are improving outcomes for patients in Kentucky and beyond. UofL’s Center for Cancer Immunology and Immunotherapy (CCII), established in 2020, has been at the forefront of exciting developments in immunotherapy, using the patients’ own immune system to defeat cancer.
That work will continue and expand at UofL thanks to $11.5 million in new funding from the National Institutes of Health. The funding ...
Survey: Californians don’t know cannabis driving laws
2025-10-22
A new study from University of California San Diego has found that, while a third of Californians use cannabis regularly, there are significant gaps in knowledge around cannabis use and driving. The researchers found that even six years after the legalization of recreational cannabis use, adults in California demonstrate mixed awareness and knowledge of driving-related laws and regulations.
The study results, published in BMC Public Health, come from a large-scale survey of cannabis use in California, titled Impact 64, which was funded by the California ...
Gum disease and cavities linked to increased stroke risk
2025-10-22
EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, OCTOBER 22, 2025
Highlights:
A new study finds that having both gum disease and cavities is linked to an 86% increased risk of stroke compared to having a healthy mouth.
Poor oral health was tied to a 36% higher risk of heart attacks and other cardiovascular events.
People with regular dental visits were 81% less likely to have both gum disease and cavities.
Researchers say improving oral health could be an important — and often overlooked — way to help reduce stroke risk.
MINNEAPOLIS – People with both cavities and gum disease may face a higher risk of ischemic stroke, according to a study ...
Gum disease associated with changes in the brain
2025-10-22
EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, OCTOBER 22, 2025.
MINNEAPOLIS – Adults with gum disease may be more likely to have signs of damage to the brain’s white matter, called white matter hyperintensities, than people without gum disease, according to a new study published on October 22, 2025, in Neurology® Open Access, an official journal of the American Academy of Neurology.
White matter refers to nerve fibers that help different parts of the brain communicate. Damage to this tissue can affect memory, thinking, balance and coordination and has been linked to higher stroke risk.
White matter hyperintensities are bright spots that appear on ...
