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.
Three lots of a drug designed to treat various urinary tract infections have been recalled because the white round tablets might have black spots from microbial contamination.
The use of 3D printers to create living tissues and organs is revolutionizing medicine—but University of Queensland research reveals the legal system is struggling to keep up as the technology races ahead.
New research from the University of Minnesota Medical School demonstrates that using cardiovascular magnetic resonance imaging—known as CMR phenotyping—can help identify patients with suspected cardiac sarcoidosis who are at increased risk of sudden cardiac death.
Sepsis is when the immune system overshoots its inflammatory reaction to an infection, so strongly that the vital organs begin to shut down. It is life-threatening: each year in the US alone, approximately 750,000 patients are hospitalized for sepsis, of which approximately 27% die.
Ivory Coast announced a cholera outbreak on Thursday, confirming seven deaths from the disease.
A Canadian infant who was born prematurely and had measles has died, officials said Thursday without confirming a cause of death, raising heightened concern about the virus's resurgence.
Can a small fish help identify possible treatments for an ultra-rare inherited disease found in an Alabama boy? The genetic disease is XMEA, which progressively weakens the muscles and can affect the liver and heart. XMEA stands for X-linked myopathy with excessive autophagy. As of March 2024, only 33 cases had ever been seen worldwide.
In a new report published in JAMA Cardiology, health policy experts at the Richard A. and Susan F. Smith Center for Outcomes Research at Beth Israel Deaconess Medical Center (BIDMC) have shown that many US adults are unaware they have high blood pressure, diabetes and high cholesterol—three major risk factors for cardiovascular disease and death.
Medical imaging scans that create detailed images of the body's internal structures are widely used in medicine. Doctors need them to detect and manage certain types of cancer, assess the extent of traumatic injuries, and diagnose and treat many other medical conditions.
A quarter of deaths in the UK are caused by heart disease, the equivalent of one person every three seconds. Improving diagnostics will allow for earlier diagnosis and better health outcomes.
Colorectal cancer (CRC) remains one of the leading causes of cancer-related deaths worldwide. While genetics and age are well-known risk factors, growing evidence highlights a significant connection between obesity and colorectal cancer. Understanding this link is crucial in shaping effective prevention and early detection strategies.
A new study provides a comprehensive overview of the current state of metabolomics research in arterial stiffness on a less explored aspect: early vascular aging, particularly in adolescents. The study offers hope for innovative approaches to vascular health.
Nearly one-third of people who adopted and adhered to a healthy diet did not lose any weight, but still reaped many health benefits, according to a new study led by researchers at Harvard T.H. Chan School of Public Health and Ben Gurion University, Israel.
Opioid overdoses are a major public health issue in the U.S., killing tens of thousands of people every year. The medicine naloxone, which is available as an over-the-counter nasal spray or given by injection, has saved countless lives by rapidly reversing opioid overdoses. But in blocking opioid receptors in the brain, naloxone causes severe withdrawal symptoms, including pain, vomiting and agitation.
Imagine diagnosing cancer not with a supercomputer but on an ordinary laptop instead. Sounds like science fiction? Thanks to a revolutionary artificial intelligence (AI) model developed by Professor Kenji Suzuki and his research team from Institute of Science Tokyo (Science Tokyo), this far-fetched scenario is now a reality.
For over a decade, scientists have been growing organoids—small clusters of cells that mimic a particular organ—to serve as miniature biological models. Organoids of the brain have been used to study neurodevelopmental disorders; intestinal organoids, to model celiac disease; and lung organoids, to investigate SARS-CoV-2. Heart organoids have even been sent to space to test the effect of microgravity on cardiac muscle. But there's a tiny problem—the organoids can't grow any bigger than a sesame seed.
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.
Researchers at the University of California San Diego School of Medicine have developed a gene therapy for Alzheimer's disease that could help protect the brain from damage and preserve cognitive function. Unlike existing treatments for Alzheimer's that target unhealthy protein deposits in the brain, the new approach could help address the root cause of Alzheimer's disease by influencing the behavior of brain cells themselves.
