Traces of highly potent synthetic opioids found in used syringes

A growing number of Americans are turning to ketamine—long used as a surgical anesthetic and known for recreational misuse—as a powerful treatment for depression and post-traumatic stress disorder, or PTSD. A new University of Florida study, led by 2024 graduate Shahar Almog, Ph.D., suggests that the drug may offer even more mental health benefits than previously thought.

Federal health authorities, headed now by U.S. Health Secretary Robert F. Kennedy Jr., are embracing vaccine hesitancy in a way they never have before.

AI-based medicine will revolutionize care, including for Alzheimer's and diabetes, predicts a technology expert, but it must be accessible to all patients.

In the largest Nordic study to date concerning esophageal cancer surgery, the researchers found clear evidence that decompression with a nasogastric tube is associated with less serious complications. Their results challenge a trend of declining use of the nasogastric tube after major surgical procedures.

Changes in Missouri law expanding breast cancer screening coverage have led to increased screening rates among Medicaid patients and an increased likelihood of digital breast tomosynthesis (DBT) among those undergoing screening, according to a study published online in the Journal of the American College of Radiology.

Researchers from the National University of Singapore (NUS) have revealed that diet and exercise can change gene regulation in the skeletal muscle of East Asians, highlighting the critical role of gene-lifestyle (G x L) interactions in metabolic health. The findings have been published in the Journal Cell Genomics.

A new study led by researchers at the Ineos Oxford Institute for Antimicrobial Research (IOI) has found that antimicrobial-resistant bacteria is spreading rapidly among children being treated for severe malnutrition in a hospital facility in Niger. The findings are published in Nature Communications.

A two-drug combination for treating advanced kidney cancer has shown sustained and durable clinical benefit in more than five years of follow-up, according to a study published in Nature Medicine.

Binge eating, especially on high-fat, high-sugar foods, can rewire the brain and alter behavior, leading to compulsive food-seeking and a greater likelihood of overeating instead of under-eating when stressed. It can also contribute to long-term physical health problems, according to a new review of animal studies.

The factors that raise the risk of heart disease and stroke can also raise the risk of dementia. When blood vessels are damaged or blocked, it can deprive your brain of vital oxygen and nutrients, and that could lead to vascular dementia.

Tiny shards of plastic called microplastics have been detected accumulating in human brains, but there is not yet enough evidence to say whether this is doing us harm, experts have said.

The aftermath of a disaster—whether natural or man-made—can be difficult. Survivors often face destroyed homes, missing loved ones and financial difficulty. In the midst of chaos, mental health often moves to the back burner.

By understanding differences in how people's brains are wired, clinicians may be able to predict who would benefit from a self-guided anxiety care app, according to a new analysis from a clinical trial led by Weill Cornell Medicine and NewYork-Presbyterian investigators.

The incidence of murder-suicide in the United States is higher than earlier estimates suggest, according to new research from the Columbia University Mailman School of Public Health. The study reveals that while murder-suicide events remain relatively rare, they are occurring more frequently than previously documented—particularly among current or former intimate partners. The findings are published in JAMA Network Open.

A new study by Bournemouth University (BU) and University Hospitals Dorset (UHD) has revealed the benefits of spinning for patients with hip osteoarthritis. The study is published in The Lancet Rheumatology.

A collaborative study between Dana-Farber Cancer Institute and the Broad Institute found that 8.9% of children with glioma, the most common form of pediatric brain tumor, have alterations in the fibroblast growth factor receptor (FGFR) family of proteins, and that these gliomas may be sensitive to existing U.S. Food and Drug Administration (FDA) approved inhibitors that broadly block FGFR.

To diagnose either type 2 diabetes or pre-diabetes, clinicians typically rely on a lab value known as HbA1c. This test captures a person's average blood glucose levels over the previous few months. But HbA1c cannot predict who is at highest risk of progressing from healthy to prediabetic, or from prediabetic to full-blown diabetes.

US President Donald Trump told major pharmaceutical firms Thursday to lower prices or face punishment, as he moved to give Americans relief from medicine costs much higher than elsewhere in the world.
