Effects of Saccharomyces boulardii on microbiota composition and metabolite levels in the small intestine of constipated mice.
Article in BMC microbiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Saccharomyces boulardii (S. boulardii) is a fungal probiotic used to treat digestive disorders. However, the mechanism(s) by which S. boulardii affects the small intestine remains unclear. Here, we aimed to explore the effects of S. boulardii on the small intestine and the underlying mechanisms in mice with loperamide-induced constipation. While S. boulardii administration did not fully reverse the alterations in loperamide-induced defecation parameters, it altered the small intestinal floral composition toward a community conducive to alleviate constipation. Moreover, S. boulardii up-regulated the expression of tyrosine-protein kinase Kit (c-Kit), aquaporin 3 (AQP3), interleukin (IL)-10, myosin light chain kinase (MLCK), and phosphorylated myosin light chain 20 (P-MLC20), while concurrently down-regulating the expression levels of inducible nitric oxide synthase (iNOS), p65, and IL-17 A. These alterations indicate a discernible effect of small intestinal water reabsorption, inflammatory factor levels, and smooth muscle contraction. Saccharomyces boulardii also positively regulated small intestinal metabolite levels, such as fructose 6-phosphate, dihomo-alpha-linolenic acid, and 3-(4-hydroxyphenyl) lactate, and participated in metabolic pathways such as arginine biosynthesis, linoleic acid metabolism, and protein digestion and absorption. While not fully reversing defecation changes, Saccharomyces boulardii alters intestinal flora, up-regulates key proteins affecting water reabsorption and inflammation, and positively influences metabolic pathways. Our study provides serves as a basis for further studies on the application of S. boulardii in the treatment of intestinal disorders.
