Objective: This study analyzed the relationship between methane production and colonic transit time in children with chronic constipation.

Methodology: Forty children, from 3 to 13 years of age, suffering from chronic constipation were included. Methane production was defined when the breath methane concentration was greater than 3 ppm. The total and segmental colonic transit times were measured with radio-opaque markers.

Results: Soiling was present in 34 (85.0%) of 40 patients with constipation. Methane production was present in 25 of 34 (73.5%) patients with constipation and soiling and only in 1 (16.7%) of 6 with constipation but without soiling (P = 0.014). The medians of total colonic transit time were 80.5 and 61.0 hours, respectively (P = 0.04), in methane and nonmethane producers. Segmental colonic transit times were 17.5 and 10.5 hours, respectively (P = 0.580), in right colon, 29.5 and 10.5 hours (P = 0.001), respectively, in left colon, and 31.5 and 27.0 hours (P = 0.202), respectively, in the rectosigmoid. By the sixth week of treatment, the reduction in the total colonic transit time was greater in patients who had become nonmethane producers.

Conclusion: The presence of breath methane in children with chronic constipation may suggest the possibility of prolonged colonic transit time.

Background: Recent studies show that the increase in breath hydrogen (BH) and symptoms after ingestion of inulin is reduced by co-administering psyllium.

Objectives: To determine if slowing delivery of inulin to the colon by administering it in divided doses would mimic the effect of psyllium. Primary endpoint was the BH area under the curve AUC.

With a high mortality rate, colon cancer (CC) is the third most common malignant tumor worldwide. The primary causes are thought to be the high invasiveness and migration of CC cells. The functions of Golgi phosphoprotein 3 (GOLPH3), stress-induced phosphoprotein 1 (STIP1), and the signal transducer and activator of transcription 3 (STAT3) signaling pathway in the invasion and migration of CC cells were examined in this study.

How the gut microbiota and immune system maintain intestinal homeostasis in concert with the enteric nervous system (ENS) remains incompletely understood. To address this gap, we assessed small intestinal transit, enteric neuronal density, enteric neurogenesis, intestinal microbiota, immune cell populations and cytokines in wildtype and T-cell deficient germ-free mice colonized with specific pathogen-free (SPF) microbiota, conventionally raised SPF and segmented filamentous bacteria (SFB)-monocolonized mice. SPF microbiota increased small intestinal transit in a T cell-dependent manner.
