FDA calls for child-resistant packaging on nicotine pouches

When a child is critically ill, families often face one of the most heartbreaking questions imaginable: how should a medical team intervene when a patient's heart stops beating or they are unable to breathe independently?

With flu season approaching and COVID-19 remaining a threat, infectious disease expert Erin Carlson encourages people to consult with their family physicians about getting vaccinated to avoid serious illness, hospitalization or death this fall and winter.

In rural and underserved areas—particularly Native American communities—early signs of dementia often go unrecognized. This could be because access to specialized care is limited, and symptoms are easily mistaken for normal memory loss due to aging.

Scientists have found that the diabetes/weight loss drug semaglutide, sold commercially under brand names like Ozempic and Wegovy, significantly reduces cocaine-seeking behavior in rats. This work needs to be confirmed in humans, but it suggests that semaglutide is a candidate to be developed as a treatment for cocaine dependency; at the moment there is no effective pharmacological treatment for cocaine dependency.

Cognitive reserve (CR) is the brain's ability to maintain cognitive function despite age-related brain changes, damage or disease. It reflects an individual's capacity to cope with these changes by utilizing pre-existing cognitive strategies or developing compensatory mechanisms.

Patients with atrial fibrillation who live in neighborhoods with poor access to full-service grocery stores face sharply higher odds of stroke and death, according to a new study from Tulane University.

Deep in the Bolivian Amazon exists a forager-horticultural community called the Tsimane. Researchers look to them for insights on how the human body functioned prior to modern technologies, as their lifestyles remain the closest to that of our ancestors.

A new UCLA Health study found that taking an eight-strain probiotic daily may reduce the risk of pouchitis, a common inflammatory condition that occurs after colon removal surgery for ulcerative colitis, but the treatment may not be worth the cost depending on a patient's likelihood of flare-ups.

The recent ouster of Centers for Disease Control and Prevention Director Susan Monarez and the resignations of top officials mark not just an institutional crisis but the latest chapter in a political war on evidence-based public health. This purge is not reform. It is the culmination of a right-wing assault that began in President Donald Trump's first term, when science was mocked, expertise sidelined and conspiracy theories elevated above epidemiology.

A type of brain cell that plays a vital role in maintaining neural networks and repairing injuries lies at the core of a promising new study on Alzheimer's disease from the USF Health Byrd Alzheimer's Center and Research Institute.

Two new papers from Clinical Gastroenterology and Hepatology and Gastroenterology shed light on how gut-brain interactions, influenced by both biology and life circumstances, shape eating behaviors. Together, they highlight the importance of multidisciplinary, personalized approaches to digestive health and nutrition.

As we age, what and how much we eat tends to change. However, how meal timing relates to health remains less understood. Researchers at Mass General Brigham and their collaborators studied changes to meal timing in older adults and discovered people experience gradual shifts in when they eat meals as they age.

Is it possible to treat obesity without reducing food intake? A new study co-led by Dr. Antonio Zorzano and Dr. Manuela Sánchez-Feutrie at the Institute for Research in Biomedicine (IRB Barcelona) suggests that this might be a possibility, at least in animal models.

A top health official in Florida vowed Wednesday to end all vaccine mandates in the state, including school requirements, likening the measure to prevent childhood diseases to "slavery."

Dr. Vadim Jucaud's lab at the Terasaki Institute has developed a human vascularized liver cancer-on-a-chip model to evaluate vessel remodeling and cell death in response to embolic agents. This novel platform reflects the microenvironment of liver tumors, particularly a functional and perfusable microvasculature that can be embolized. This in vitro tool aligns with the National Institutes of Health (NIH) efforts to reduce animal testing and promote alternative methods, including microfluidic devices that mimic human organs.

Colorectal cancer is unique in having its own microbial "fingerprint," according to new research from the University of East Anglia.

A new study, led by the University of Cambridge in collaboration with Bournemouth University, shows that autistic people identify loneliness, hopelessness, and feelings of worthlessness and failure as key factors underpinning their suicidal feelings. Individuals who highlighted being unable to access the support they needed were more likely to have attempted suicide. Autistic women and gender minorities were disproportionately over-represented among those who struggled to access support.

An MUSC research team reports in Cells that the complement system, part of the body's natural immune defenses, is a key driver of inflammatory responses that contribute to fetal brain inflammation and preterm birth, the latter of which is the leading cause of complications and death in newborns.
