When the U.S. Congress passed the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act in August 1990, it honored a young man who had acquired HIV from a blood transfusion five years earlier at age 13.

A new longitudinal study led by York University's Department of Psychology published today finds that young adults experiencing periods of high stress, anxiety and depressed mood more frequently combined binge drinking with cannabis use in order to get more high and drunk, and were also likely to report more adverse life consequences when combining these substances. Lead author Jeffrey Wardell, Associate Professor in York University's Faculty of Health, says that since cannabis use among young adults has increased after Canada legalized the drug, understanding why people combine the drug and outcomes when they do is important.

Despite the promise of telehealth to bridge rural health care gaps, a new study published in the Journal of Medical Internet Research reveals that many rural-dwelling patients in the United States—especially those who are older, speak Spanish, or rely on public insurance—are still struggling to access virtual care.

Psychiatrists and mental health professionals have always relied on medication and talk therapy to treat depression, but Dr. Nicholas Fabiano, a psychiatry resident at the University of Ottawa, thinks it's time for a shift. In an editorial published in the British Journal of Sports Medicine, he argues that exercise shouldn't be an afterthought, it should be a standard part of every treatment plan for patients with depression.

Lung cancer patients who take medications called GLP-1 receptor agonists—commonly prescribed for weight loss and diabetes management—fare better than those who don't, according to research led by Sai Yendamuri, MD, MBA, FACS, Chair of Thoracic Surgery at Roswell Park Comprehensive Cancer Center, and Joseph Barbi, Ph.D., Assistant Professor, Department of Immunology. Results of the study, which involved investigators from both Roswell Park and the Columbia University Irving Medical Center, appear in JCI Insight.

It's a well-known fact that fetal alcohol spectrum disorder (FASD) in children is caused by mothers who drink during pregnancy. But it turns out that the father's drinking habits could also affect a child's growth and development.

In a move that could reshape drug discovery, researchers at Harvard Medical School have designed an artificial intelligence model capable of identifying treatments that reverse disease states in cells.

Diet doesn't just fuel the body, it sends molecular signals that can slow down or speed up biological aging, according to a new perspective in npj Aging. The authors explain that biological age, a measure of functional health, can diverge sharply from chronological age and that targeted nutritional and lifestyle choices can bend the trajectory toward healthier aging.

A person will have Alzheimer's years before ever knowing it. The disorienting erasure of memories, language, thoughts—in essence, all that makes up one's unique sense of self—is the final act of this enigmatic disease that spends decades disrupting vital processes and dismantling the brain's delicate structure.

The start of an academic year can bring a lot of changes into a student's life: New teachers, different classes and assignments, and updated school day routines.

New proposed federal restrictions on who can get COVID-19 vaccinations has caused confusion and worry across the country. Some states, including California, have decided to break away from federal guidelines and create their own rules for who can receive COVID-19 vaccinations.

Glioblastoma is a devastatingly effective brain cancer. Doctors can cut it out or blast it with radiation, but that only buys time. The cancer has an insidious ability to hide enough tumor cells in tissue around the tumor to allow it to return as deadly as ever.

Cardiovascular diseases remain the most common cause of death worldwide. In Europe, they account for over 40% of all deaths. However, known risk factors such as high cholesterol levels or high blood pressure cannot fully explain the high mortality rate or the number of cardiovascular diseases.

The coronavirus has muscled its way back into the headlines in recent weeks amid a summer wave of the illness and growing difficulties in getting the vaccine, as well as efforts by the Trump administration that could make getting inoculated harder for some people.

Researchers have uncovered a previously unknown mechanism that safeguards the chromosome ends from being mistakenly repaired by the cell. While DNA repair is vital for survival, attempts to repair the chromosome ends—called telomeres—can have catastrophic outcomes for cells.

A New York-based company has recalled several frozen vegetable products over possible listeria contamination, according to a report shared by the U.S. Food and Drug Administration (FDA).
