Colonoscopy screening at age 45 yields neoplasia rates close to older adults: Study supports guideline change

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 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.

A small region of the brain, known as the ventral tegmental area (VTA), plays a key role in how we process rewards. It produces dopamine, a neuromodulator that helps predict future rewards based on contextual cues. A team from the universities of Geneva (UNIGE), Harvard, and McGill has shown that the VTA goes even further: It encodes not only the anticipated reward but also the precise moment it is expected.

Researchers estimate that there are at least 5.4 million U.S. children who provide care to an adult in their home. As state officials eye federal Medicaid funding cuts that could drastically reduce home care services for those who are disabled or have chronic health conditions, many predict that number will rise.

A Denver resident is the seventh Coloradan to get measles from a passenger on a Turkish Airlines flight last month—and they may have passed the highly contagious virus on to people at three stores along the Front Range.

New research shows that weight stigma—and not weight itself—has the biggest impact on mental health and healthy behaviors in the years after weight-loss surgery.

Navajo Nation leaders took turns talking with the U.S. government's top health official as they hiked along a sandstone ridge overlooking their rural, high-desert town before the morning sun grew too hot.

A major international study presented at the 62nd ERA Congress reveals that the long-accepted survival advantage of deceased-donor kidney transplantation does not extend equally to every patient and every donor organ.

Jail time has a huge effect on both an individual's and a community's long-term health, even after their release, a new study says.

GLP-1 (glucagon-like peptide-1) therapies can be powerful tools in managing obesity, with patients taking these medications seeing weight reductions of 5%–18% in clinical trials, along with increased metabolism and benefits to their overall heart health. However, GLP-1s can come with challenges, including gastrointestinal side effects, risk of micronutrient deficiencies, muscle and bone loss, poor long-term follow-through with weight regain if stopped, and high costs.
