Abstract

fetched live from OpenAlex

Many healthy people complain of functional gastrointestinal (GI) tract symptoms that do not fit diagnostic criteria for established diseases. Disrupted intestinal microbiomes are associated with these functional conditions, thus the use of beneficial bacteria shown to restore the protective microbiome may be useful. Our aims were to determine if Heyndrickxia (Bacillus) coagulans GBI-30, 6086 (BC30) would improve GI functions in healthy adults living in China and to determine its effect on the GI microbiome. Healthy adults ( n = 111, 18-65 years old) with functional GI complaints were enrolled in a prospective, double-blind trial and randomised (by random number table) to either BC30 (1 × 109/day) or placebo for four weeks. Outcomes were analysed by ANOVA or the Wilcoxon tests or with mixed regression models. Functional GI symptoms improved significantly in adults given BC30 compared to placebo: increase in number of stools/week ( P = 0.036), improved fecal consistency ( P < 0.001) and fewer participants had constipation ( P < 0.001). Four weeks of BC30 increased intestinal Bacteroides levels and reduced Clostridium, Blautia, Ruminococcus levels but did not otherwise alter the general microbiome. BC30 significantly improved GI functions in healthy adults in China, with minor modifications of the fecal microbiome and was well-tolerated. The trial was registered at ClinicalTrials.gov (NCT06644001).

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
