Introduction: Intestinal barrier function is dependent on the structure and function of intestinal epithelial cells and paracellular pathway. The derangement of the intestinal barrier function can originate from conditions involving local and systemic chronic inflammation and metabolic diseases such as obesity and metabolic disorders. This study aims to describe a systematic review protocol investigating if obesity with or without metabolic syndrome is associated with an altered intestinal barrier function.
Methods And Analysis: This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. The databases to be searched are PubMed, Embase, Scopus, Science Direct and Web of Science. The systematic review will include original articles with adults and the elderly, who present obesity with or without metabolic syndrome, that address the intestinal barrier function. Two independent reviewers will perform study selection, data extraction and methodological quality assessment. Key information will be tabulated and a narrative synthesis will be conducted. The Grading of Recommendation, Assessment, Development and Evaluation framework will be used to assess the quality of evidence concerning the associations between intestinal barrier function and obesity with or without metabolic syndrome. The present protocol will assist in producing a systematic review that addresses if obesity with or without metabolic syndrome alters intestinal barrier function.
Ethics And Dissemination: No ethical statement will be required. The results will be disseminated through a peer-reviewed publication and conference presentations.

Type 2 diabetes (T2D) is an important risk factor for brain cognitive impairment, but the specific mechanism is still unclear. The imbalance of gut microbiota under pathological conditions (such as an increase in pathogenic bacteria) may be involved in the occurrence of various diseases. The purpose of this study is to investigate the effect of increased abundance of gut Citrobacter rodentium on cognitive function in T2D mice.

Recent studies show that inorganic arsenic (As) exerts a toxic effect on the intestinal epithelium, causing a significant increase in its permeability. This disruption of the epithelial barrier may favor the entry of contaminants or toxins into the systemic circulation, thus causing toxicity not only at the intestinal level but possibly also at the systemic level. The present study conducts an evaluation of the protective effect of various dietary supplements and plant extracts against the intestinal toxicity of inorganic As.

Pectin is an acidic heteropolysaccharide with natural, green, and inexpensive characteristics. Compared to polysaccharides, oligosaccharides are more easily utilized by the body, and the physiological function of hawthorn pectin oligosaccharides (POS) may vary depending on their degree of polymerization (DP). Therefore, we mainly studied the effects of hawthorn pectin (HP) and POS with different DP on gut microbiota disorders induced by high-fat diet (HFD).

Irinotecan (CPT11) chemotherapy-induced diarrhea affects a substantial cancer population due to -glucuronidase (Gus) converting 10--glucuronyl-7-ethyl-10-hydroxycamptothecin (SN38G) to toxic 7-ethyl-10-hydroxycamptothecin (SN38). Existing interventions primarily address inflammation and Gus enzyme inhibition, neglecting epithelial repair and Gus-expressing bacteria. Herein, we discovered that dehydrodiisoeugenol (DDIE), isolated from nutmeg, alleviates CPT11-induced intestinal mucositis alongside a synergistic antitumor effect with CPT11 by improving weight loss, colon shortening, epithelial barrier dysfunction, goblet cells and intestinal stem cells (ISCs) loss, and wound-healing.
