Social engagement is a vital component of psychological and physical well-being linked to better health and a longer life, yet many older adults struggle to maintain relationships that support these outcomes. New research from Nanyang Technological University in Singapore finds that changes in the brain's intrinsic functional connectivity networks fully account for the decline in sociability observed with aging.
Dry mouth, bad breath and tooth damage: The effects Ozempic and Wegovy can have on your mouth

Ozempic and Wegovy have been hailed as wonder drugs when it comes to weight loss. But as the drug has become more widely used, a number of unintended side-effects have become apparent—with the weight loss drug affecting the appearance of everything from your butt to your feet. "Ozempic face" is another commonly reported consequences of using these popular weight loss drugs. This is a sunken or hollowed out appearance the face can take on in people taking weight loss drugs.
Colonoscopy screening at age 45 yields neoplasia rates close to older adults: Study supports guideline change

2 days ago | medicalxpress.com | Justin Jackson |Sadie Harley |Robert Egan

Researchers from Kaiser Permanente Northern California reveal that adults aged 45 to 49 undergoing their first screening colonoscopy have neoplasia detection rates similar to those aged 50 to 54, supporting recent guideline changes to begin colorectal cancer screening earlier. Rising colorectal cancer rates among adults under 50 in the United States have prompted a shift in screening guidelines.
Diagnostic pen converts handwriting into electrical signals to detect Parkinson's

A team at the University of California, Los Angeles has developed a low-cost diagnostic pen that converts handwriting into electrical signals for early detection of Parkinson's disease, achieving 96.22% accuracy in a pilot study. Parkinson's disease impairs the motor system, leading to tremors, stiffness, and slowed movements that impair fine motor functions such as handwriting.
Satri-cel study marks first randomized CAR T-cell success in solid tumors

Satri-cel, a CLDN18.2-targeted CAR T-cell therapy, nearly doubles progression-free survival in patients with previously treated gastric or gastro-esophageal junction cancer, according to a multicenter randomized trial led by Peking University Cancer Hospital in China. Gastric and gastro-esophageal junction cancers remain among the deadliest malignancies worldwide.
Large language models excel at creating and solving emotional intelligence tests, study finds

Throughout the course of their lives, humans can establish meaningful social connections with others, empathizing with them and sharing their experiences. People's ability to manage, perceive and understand the emotions experienced by both themselves and others is broadly referred to as emotional intelligence (EI).

Millions of young women around the world face stigma and bias when seeking reproductive health services, often limiting their access to contraception and quality care. A new USC-led study conducted in over 200 clinics across Burkina Faso, Tanzania, and Pakistan shows that a focused intervention combining storytelling, peer support, and provider incentives can reduce this bias and expand contraceptive access for the young women who need it most.
Females may be more biochemically sensitive to alcohol long before dependence sets in

4 days ago | medicalxpress.com | Stephanie Baum |Robert Egan

Alcohol affects everyone differently, but new research reveals that biological sex may play a bigger role than previously thought. In a preclinical study published in Biological Psychiatry, Scripps Research scientists have uncovered distinct differences in how the brains of female rats respond to alcohol—and found early evidence that the effectiveness of certain medications varies depending on drinking history and sex.
Study identifies proteins involved in the effectiveness of immunotherapy against blood cancer

4 days ago | medicalxpress.com | Stephanie Baum |Robert Egan

A study conducted by researchers at the Center for Cell-Based Therapy (CTC) highlights key proteins and signaling pathways involved in the efficacy of immunotherapy based on CAR-T cells (lymphocytes modified in the laboratory to fight cancer). The CTC is a Research, Innovation, and Dissemination Center based at the Ribeirão Preto Medical School of the University of São Paulo (FMRP-USP) in Brazil.
Wearable tech returns results of varying accuracy for fitness metrics: Study

4 days ago | medicalxpress.com | Jordan Karnbach |Stephanie Baum |Andrew Zinin

Many Americans rely on their Apple Watches or similar devices each day to count their steps, track workouts, and measure how many calories they burn. But are those wearable devices accurate? University of Mississippi professor Minsoo Kang and doctoral student Ju-Pil Choe are working to answer that question. Kang, a professor of sports analytics, and Choe reviewed 56 studies that compared the Apple Watch to trusted reference tools in measuring energy burned, heart rate and step counts.
