Summary: This study investigated the effects of simulated oro-gastrointestinal transit stress on the adhesion and survival of Lactobacillus plantarum S7, a potential probiotic strain. Results showed that L. plantarum S7 had a higher survival rate under certain bile salt concentrations and its adhesion ability was enhanced after exposure to specific stress conditions. Furthermore, the expression of surface proteins and pathways related to oro-gastrointestinal transit stress were regulated in L. plantarum S7. Overall, L. plantarum S7 showed strong resistance to oro-gastrointestinal stress, making it a promising probiotic candidate.

Summary: This study examines the association between the status of gastroduodenal disease and the lactulose hydrogen breath test (LHBT) results. The findings suggest that aDU patients with a positive Hp infection have less severe gastric mucosa damage compared to iDU patients and tend to have a higher level of exhaled hydrogen after LHBT.

Summary: The study identified that high methane emitters have a significant increase in Methanobrevibacter smithii in their microbiome, which co-occurs with a bacterial community specialized in dietary fiber degradation. High methane producers also show increased levels of formate and acetate in the gut, closely correlated with dietary habits and microbiome function, driving archaeal methanogenesis.

Summary: Through systematic searches and meta-analysis of related studies, this article demonstrates the feasibility and potential of utilizing exhaled volatile organic compounds (VOCs) for diagnosing gastrointestinal cancers. The results show promising sensitivity and specificity of VOC analysis in diagnosing colorectal cancer (CRC) and gastroesophageal cancer (GEC), indicating that VOCs could serve as valuable tumor biomarkers for gastrointestinal cancer diagnosis.

Summary: The study found that the average occurrence rate of microplastics in the gastrointestinal tracts of fish globally is 2.76 P/gt. Microplastic occurrence in closed water sources is higher than in free water sources, and the occurrence varies in different water sources. The occurrence rate of microplastics in the gastrointestinal tracts of fish in high-income economies is lower than in low-income economies, with blue polyethylene-type microplastics having a higher frequency. Control plans to reduce microplastic occurrence in fish are recommended.

Summary: Intestinal dysbiosis and small intestinal bacterial overgrowth (SIBO) are common in patients with liver cirrhosis. The association between gut dysbiosis and SIBO has not been explored in existing studies. Suggestions for improving experimental methods and concepts are proposed, and it is recommended to exclude interference from other gastrointestinal diseases and to use the hydrogen breath test for higher accuracy.

Summary: A learning enabled microultrasound system was proposed to classify inflamed and non-inflamed bowel tissues, allowing for robust differentiation between healthy tissue and tissue with early signs of inflammation. This method may lay the foundation for future early GI disease diagnosis and enhanced management with computer-aided imaging.

Summary: The increased availability of noninvasive breath tests has led to widespread testing for small intestinal bacterial overgrowth. The glucose breath test should be exclusively employed for diagnosing SIBO, while the lactulose breath test should be discarded.

Summary: This meta-analysis found a positive association between chili pepper consumption and certain gastrointestinal (GI) cancers, such as esophageal cancer (EC). The risk of GI cancers varies by geographical region, especially in Asian, African, and North American populations.

Summary: The study suggests that in children with functional gastrointestinal disorders, positive fructose hydrogen breath tests (HBTs) may be attributed to their younger age rather than any specific clinical features of the disease.

Summary: This study reports an oral radioprotectant Gel@GYY that combines a gelatin-based hydrogel and a pH-responsive hydrogen sulfide donor. Gel@GYY has excellent adhesion and sustained release properties, allowing it to release H2S in the gastrointestinal tract and effectively scavenge free radicals induced by radiation. It also reduces inflammation and has biodegradable properties.

Summary: Endoscopic vacuum therapy (EVT) is an effective and safe treatment for transmural defects of the upper gastrointestinal (UGI) tract, including perforations, leaks, and fistulae. EVT has a higher successful closure rate compared to self-expanding metal stent (SEMS) placement for UGI defects.

Summary: This systematic review found that probiotic supplements can reduce the risk of gastrointestinal infections in infants and children attending childcare centers, with certain strains showing specific potent effects. However, there is insufficient evidence to determine the effectiveness of Bifidobacterium animalis subsp. lactis BB-12 based on the included trials.
