	Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria.

	Could a daily vinegar drink help with constipation? A small trial offers a clue A randomized, double-blind trial found that adults with mild constipation who drank a vinegar beverage daily for four weeks had more frequent bowel movements than those receiving placebo. Exploratory findings also suggested earlier improvements in bowel habits, although the small feasibility-based trial requires confirmation in larger and more diverse populations.

			A striking immune cell pattern emerges around a person’s 100th birthday Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

			Only 15% of eligible American adults discuss lung cancer screening with their doctors Lung cancer screenings can save lives by detecting cancer in its early stages, but only 15% of eligible American adults have discussed the screening with their doctors, according to data analysis performed by University of Cincinnati Cancer Center researchers.

			New discovery helps identify colorectal cancer patients at risk for metastasis Researchers from the University of Turku in Finland and Gustave Roussy Institute in France have discovered a molecular mechanism that regulates whether the cells of an aggressive colorectal cancer are conventional or inverted when they spread in the body.

	New review examines why tetanus remains a global health problem Tetanus is often considered a disease of the past, remembered mainly through childhood vaccinations and warnings about rusty nails.

	Active screening cuts colorectal cancer death risk drastically People who take part in screening for colorectal cancer may have as much as 43 per cent lower risk of dying from the disease, according to new estimates published in JAMA Network Open by researchers at Karolinska Institutet and Umeå University in Sweden.

	Study maps rising lifetime risk of digestive cancers in China The global landscape of oncology is shifting, and nowhere is this transition more complex or consequential than in China.

	Sprinters and non-athletes had similar gut diversity, but one key difference emerged College sprint athletes showed a distinct gut microbial community structure, including higher abundance of Segatella copri and Bifidobacterium adolescentis, compared with non-athletic students. Their microbiomes also showed predicted enrichment of carbohydrate and amino acid metabolism pathways, while exploratory analyses linked several dietary factors with the signature bacteria.

	New study tracks global colorectal cancer risk across 185 nations Colorectal cancer has long been recognized as a major global health threat, but its burden is far from evenly distributed. Incidence and mortality rates vary dramatically across countries, and these differences are closely tied to socioeconomic development, dietary transitions, and the adoption of screening programs.
