Ecological patterns of the gut mycobiome and microbiome in ulcerative colitis across life stages.

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
Introduction: Age-related variations in the gut microbial communities may influence immune regulation and inflammatory processes in inflammatory bowel diseases (IBD). However, distinguishing age effects from differences in clinical characteristics remains challenging. Methods: We investigated life-stage-associated patterns of the gut microbiome and mycobiome while accounting for clinical heterogeneity between paediatric and adult ulcerative colitis (UC) populations. We analysed 73 targeted metagenomes of bacteria and 69 targeted metagenomes of fungi from 26 paediatric and 47 adult patients with UC. Microbial diversity metrics and multivariate analyses were applied to evaluate community variation, and mucosal immune markers were assessed by ELISA. Clinical variables, including disease activity, duration, and treatment exposure, were considered when interpreting age-related microbial differences. Results: Fungal communities exhibited higher richness in adults and formed distinct age-related clusters in beta-diversity analyses, whereas bacterial composition remained largely comparable across age groups. Children were enriched in inflammation-associated fungi (Saccharomycetes, Discussion: Age-related variation was more evident in fungal than bacterial communities, suggesting that host developmental and immunological factors contribute to mycobiome configuration beyond clinical imbalance alone. Together, these findings indicate that life stage is linked to ecological variation of the gut mycobiome and mucosal immune responses in UC, while bacterial communities appear primarily shaped by disease-related factors. The transition from childhood to adulthood may represent a critical window of host-fungal interaction relevant for age-tailored microbiome-based strategies.
