Ultraprocessed food consumption and risk of early-onset colorectal cancer precursors among women

JAMA Oncology

2025-11-13

(Press-News.org) About The Study: In this study, higher ultraprocessed food intake was associated with increased risk of early-onset colorectal conventional adenomas. These data highlight the important role of ultraprocessed foods in early-onset colorectal tumorigenesis and support improving dietary quality as a strategy to mitigate the increasing burden of early-onset colorectal cancer.

New study could help your doctor make smarter treatment decisions

2025-11-13

Thoughtful electronic health record system design can nudge physicians toward evidence-based, less invasive treatments Doctors offered two or more treatment alternatives were significantly more likely to choose a better option (62%) than those offered only one (44%) ‘We’re trying to make it easier for physicians to do the right thing’ CHICAGO --- Having more options is always better — until it’s not. Doctors face this paradox daily when choosing treatment plans for patients, especially under the pressure of packed clinical schedules. Too few choices can limit care, but too many can lead to decision ...

Study finds adults who consumed more ultra-processed foods had higher rates of precursors of early-onset colorectal cancer

2025-11-13

Colorectal cancer used to be associated with old age, but diagnoses have become increasingly common in adults aged 50 or younger particularly in high-income countries like the United States. The reason for this trend is unclear, but a new study led by Mass General Brigham researchers, as part of the Cancer Grand Challenges PROSPECT team, suggests an important link to ultra-processed foods that merits closer investigation. By analyzing the diets and endoscopy results from almost 30,000 women, the team ...

Pancreatic cancer research project attacks ‘seeds of metastasis’

2025-11-13

Pinned between the stomach and spine, the pancreas supervises both digestion and blood sugar in the body. It’s also the site of an aggressive cancer called pancreatic ductal adenocarcinoma, or PDAC. PDAC is the most common type of pancreatic cancer, the third-leading cause of cancer deaths in the U.S. It’s difficult to detect and recurs about 70% of the time after treatment. Only 13% of those diagnosed survive more than five years. A team of surgeons, anesthesiologists and engineers at the University of ...

How can AI sentiment analysis apply to complex medical diagnoses?

2025-11-13

Taking a page from market research tactics, UC San Francisco experts are studying whether artificial intelligence (AI) can improve diagnosis of a complex liver condition by using the clinical notes of multiple providers. Their recent study, published in Gastro Hep Advances, focused on hepatorenal syndrome (HRS), a complex condition associated with liver disease that is often difficult to diagnose during hospitalization. The researchers sought to learn if large language models could analyze the clinical notes of multiple physicians and other providers to improve ...

1st death linked to ‘meat allergy’ spread by ticks

2025-11-13

University of Virginia School of Medicine researchers have identified the first death caused by what is commonly called the “meat allergy” being spread by ticks. A healthy 47-year-old man from New Jersey died abruptly four hours after consuming beef. The cause of his death had been a mystery until UVA Health’s Thomas Platts-Mills, MD, PhD, investigated. A world-renowned allergist, Platts-Mills discovered the allergy and remains the foremost expert on it. The allergy is caused by the bite of the Lone Star tick. Bites can sensitize people to alpha-gal, a sugar found in mammalian meat. People who become sensitized to the sugar can have allergic symptoms such as rash, nausea ...

The role of hepatic SIRT1: From metabolic regulation to immune modulation and multi-target therapeutic strategies

2025-11-13

Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as the most prevalent chronic liver disorder globally, with a rising incidence linked to metabolic syndrome. Its pathogenesis involves a complex interplay of lipid metabolic dysregulation, insulin resistance, oxidative stress, chronic inflammation, and gut-liver axis disruption. Despite recent advances such as Resmethron for advanced metabolic-associated steatohepatitis (MASH), early-stage interventions remain limited. This ...

2025 AAAS Kavli Science Journalism Award Winners Named

2025-11-13

Stories describing what can happen when science is manipulated or misapplied are among the winners of the 2025 AAAS Kavli Science Journalism Awards. Winning journalists also did stories on science at its best, revealing new understanding about the natural world. Independent panels of science journalists select the winners of the awards, which are administered by the American Association for the Advancement of Science (AAAS) and endowed by The Kavli Foundation. There is a Gold Award ($5,000) and Silver Award ($3,500) for each of the eight categories. The global awards program drew entries from 67 countries this year, and 55 percent of the ...

Helping the youngest children thrive at school

2025-11-13

Well-being and school results are inter-connected, but some children simply do not enjoy school. So what can we do to make school a happier experience for more children? Professor Hermundur Sigmundsson works at the Norwegian University of Science and Technology (NTNU’s) Department of Psychology and has spent many years conducting research on learning and schooling. He and his colleagues are currently carrying out a project in Vestmannaeyjar in Iceland. Among other things, they have investigated ...

During a heart attack immediate stenting of other arteries isn’t always necessary

2025-11-13

A blocked coronary artery causing an acute heart attack must be opened immediately with a stent procedure. However, if other coronary arteries also appear to be narrowed, it is safe to wait and treat those later. This approach cuts the number of stent procedures in half, according to cardiologists from Radboud university medical center, writing in The New England Journal of Medicine. Each year, 33,600 people are admitted to the hospital with a heart attack. In those cases, doctors must quickly open the blocked artery with angioplasty to prevent part of the heart muscle from dying. Yet during the procedure, it often becomes ...
