Intermittent fasting exacerbates microplastic-induced gut inflammation via Rikenella-mediated regulation of purine metabolism and Th17/Treg balance.

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
The pervasive accumulation of microplastics (MPs) in ecosystems and human bodies has prompted growing concern regarding their biological effects. However, whether intermittent fasting (IF) modulates MP-induced gut injury remains unclear. We established a murine model of chronic oral exposure to 1 μm polystyrene MPs combined with a daily 8-h feeding window. Multi-omics analyses, including 16S rRNA sequencing, untargeted metabolomics, and immune profiling, were performed. In a murine model of chronic oral exposure to 1 μm polystyrene microplastics, IF aggravated colonic inflammation and oxidative stress. 16S rRNA sequencing showed that IF further altered the microplastic-associated gut microbiota, notably reducing Rikenella abundance. Untargeted metabolomics revealed disrupted purine metabolism, including decreased hypoxanthine levels, which positively correlated with Rikenella. Combined MP and IF exposure was associated with an increased Th17/Treg ratio. Supplementation with Rikenella or hypoxanthine partially attenuated inflammatory changes. These findings unveil a previously unappreciated risk of IF under conditions of environmental microplastic exposure, and highlight the necessity of integrating environmental toxicants into evaluations of dietary interventions.
