The increasing prevalence of type 2 diabetes (T2DM) worldwide has become a burden to healthcare systems. In 2019, around 463 million adults were living with diabetes , and T2DM accounted for 90 to 95% of cases. The relationship between the gut microbiota and T2DM has been explored with the advent of metagenomic techniques. Genome-wide association studies evaluating the microbiota of these individuals have pointed to taxonomic, functional, and microbial metabolite imbalances and represent a potential intervention in T2DM management. Several microbial metabolites and components, such as imidazole propionate, trimethylamine, and lipopolysaccharides, appear to impair insulin signaling, while short-chain fatty acids, secondary bile acids, and tryptophan metabolites may improve it. In addition, the use of probiotics with the aim of transiently restoring the microbial balance or reducing the effects of microbial metabolites that impair insulin sensitivity has been explored. Herein, we critically review the available literature on the changes in the gut microbiota in T2DM together with potential adjuvant therapies that may improve the health status of this population.

Background: Complex perianal fistulas, challenging to treat and prone to recurrence, often require surgical intervention that may cause fecal incontinence and lower quality of life due to large surgical wounds and potential sphincter damage. Human umbilical cord-derived MSCs (hUC-MSCs) and their exosomes (hUCMSCs-Exo) may promote wound healing.
Methods: This study assessed the efficacy, mechanisms, and safety of these exosomes in treating complex perianal fistulas in SD rats.

Background: Evidence has revealed that oestrogen deprivation-induced osteolysis is microbiota-dependent and can be treated by probiotics. However, the underlying mechanism require further investigation. This study aims to provide additional evidence supporting the use of probiotics as an adjuvant treatment and to explore the pathophysiology of oestrogen-deprived osteolysis.

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.

Background: Kombucha, a fermented beverage obtained from a Symbiotic Culture of Bacteria and Yeast (SCOBY), has shown potential in modulating gut microbiota, although no clinical trials have been done.
Objective: We aimed to evaluate the effects of regular black tea kombucha consumption on intestinal health in individuals with and without obesity.
Methods: A pre-post clinical intervention study was conducted lasting eight weeks.

The gut microbiota plays a crucial regulatory role in various physiological processes, yet its impact on corneal homeostasis remains insufficiently understood. Here, we investigate the effects of antibiotic-induced gut dysbiosis (AIGD) and germ-free (GF) conditions on circadian gene expression, barrier integrity, nerve density, and immune cell activity in the corneas of mice. Through RNA sequencing, we found that both AIGD and GF conditions significantly disrupted the overall transcriptomic profile and circadian transcriptomic oscillations in the cornea.
