Another great day at #UEGWeek 2025! 🎉Congratulations to our colleague Jorge Vazquez Castellanos for presenting his exciting work on microbial dysbiosis, inflammation, and the gut–brain axis in IBS at the United European Gastroenterology Week in Berlin🇩🇪 @myueg.bsky.social @vibmicrobes.bsky.social

Huge congratulations to our colleague @arnauvich.bsky.social for presenting his research on FODMAP restriction and gut microbiota in IBS patients at United European Gastroenterology Week 2025 in Berlin🇩🇪👏! #UEGWeek @myueg.bsky.social @vibmicrobes.bsky.social

The most interesting report of the week (IMHO) 🧵

New hope for Alzheimer’s: lithium supplement reverses memory loss in mice Studies in rodents and humans suggest that low levels of the metal contribute to cognitive decline.

Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses - Nature Phagocytosed bacteria can serve as an alternative nutrient source for macrophages, influencing their metabolic and immune responses through the recycling of microbial components, with the process regulated by nutrient-sensing mechanisms and bacterial viability.

Commonly used compositional data analysis implementations are not advantageous in microbial differential abundance analyses benchmarked against biological ground truth Previous benchmarking of differential abundance (DA) analysis methods in microbiome studies have employed synthetic data, simulations, and "real data" examples, but to the best of our knowledge, none ...

Excited to share our MicrobiomeBenchmarkData preprint, addressing compositional data analysis for microbiome DA. This Bioconductor package features 3 datasets with biological ground truths. Spoiler: simple methods like LEfSe, Wilcoxon, RNA-seq methods performed well www.biorxiv.org/content/10.1...
