Stanford Medicine researchers have identified a primary driver of biological aging: the failure of tissue-resident macrophages to clear senescent, or “zombie,” neutrophils from the body. According to a study published July 16 in Science, blocking a specific pro-inflammatory receptor, EP2, on these immune cells rejuvenated organ function and reduced age-related frailty in mice. This discovery … Read more
A combination of dietary fibers from wheat, citrus, and oats significantly improves bowel movement frequency and stool consistency in adults with chronic functional constipation, according to a randomized clinical trial published in the journal Food Science & Nutrition. Researchers found that a daily 13-gram supplement dose containing resistant dextrin, pectins, and insoluble fiber provided faster … Read more
The loss of the transcription factor GATA6 acts as a biological switch that reprograms colorectal cancer cells to metastasize to the liver, according to research published June 22 in Cell Stem Cell. By silencing this “identity keeper,” cancer cells adopt a flexible, fetal-like state that allows them to travel through the bloodstream and colonize distant … Read more
Researchers from the Wellcome Sanger Institute and the Francis Crick Institute have identified a genetic marker, HLA-DRB1*01:03, that correlates with more severe ulcerative colitis and Crohn’s disease. Published in The Lancet Gastroenterology and Hepatology, the study suggests that genetic testing could help clinicians identify high-risk patients for earlier intervention with advanced therapies. How does the … Read more
Robot-assisted colon resection remains technically feasible across multiple platforms, though recent data indicates performance variations between the Da Vinci, Hugo RAS, and Versius systems. In a prospective study of 45 patients conducted between February and December 2024, researchers found that while all three platforms successfully performed colorectal surgeries, the systems differed in operating room efficiency … Read more
Americans with the highest levels of obesity are undergoing fewer surgical procedures, despite a rising national prevalence of severe obesity. A study published in the journal Obesity, which analyzed 11.6 million surgical cases between 2005 and 2022, found that patients with higher body mass index (BMI) levels are increasingly underrepresented in surgical care for common … Read more
Engineering the Future of Regenerative Medicine: Lab-Grown Gut Tissue A breakthrough in organoid research is changing the landscape of regenerative medicine. Researchers at Cincinnati Children’s have developed a new “confined culture system” (CCS) that allows for the production of functional human gut organoids at a significantly accelerated pace and increased scale. Cincinnati Children By utilizing … Read more
The New Frontier of Gut-Based Cancer Prevention For decades, the medical community has viewed colorectal cancer primarily through the lens of genetics, and lifestyle. However, a paradigm shift is occurring. We are moving toward an era of precision microbiome oncology, where the focus isn’t just on the cells that become cancerous, but on the bacterial … Read more
The Hidden Trigger: How Gut Bacteria Drive Colon Cancer For years, the medical community has tracked a troubling link between the common gut bacterium Bacteroides fragilis and the formation of colon tumors. We knew this bacterium secreted a toxin—known as BFT—that damaged the colon’s lining, potentially paving the way for colorectal cancer. However, the “how” … Read more
The Evolution of Colorectal Cancer Screening: Moving Beyond the Clinic For years, the biggest hurdle in colorectal cancer (CRC) prevention hasn’t always been the technology available, but rather the logistics of getting patients to use it. In underserved community health centers, where patients face significant social and economic barriers, the traditional “come into the office” … Read more
