Sugar Intake During Antibiotic Treatment May Worsen Gut Microbiome Disruption

Consuming sweets and simple sugars during antibiotic treatment was associated with greater gut microbiome disruption, including reduced microbial diversity and expansion of the pathobiont Enterococcus. In this study, researchers precisely tracked 9,419 meals consumed by 173 patients undergoing haematopoietic cell transplantation and analyzed longitudinal microbiome changes in 158 patients with […]


Early Brain Ageing Linked to the Gut–Brain Axis

Higher functional-connectivity-derived brain age deviation was consistently associated with poorer cognitive performance—particularly working memory and executive function—and greater depressive symptoms in young and mid-life adults, while also showing links to gut microbial and metabolic signatures. In a discovery cohort of 674 participants, with replication in a cohort of 444 and […]


Higher TMAO Levels Linked to Greater Risk of Abdominal Aortic Aneurysm

Higher blood levels of the gut microbiome-derived metabolite trimethylamine N-oxide (TMAO) were independently associated with an increased risk of developing abdominal aortic aneurysms (AAAs) and experiencing serious AAA-related events in apparently healthy older adults. Researchers measured plasma TMAO levels in 4,442 community-dwelling adults aged 65 years or older from the […]
