Numerous studies have revealed that the gut microbiome of people with obesity and T2D differs significantly from those of healthy people. Those who suffer from certain illnesses often encounter disruption in their gut microbiome, leading to a decrease in richness diversity and diminished microbial activity. This disruption can also result in the loss of the gut mucosal barrier, increased gut permeability, and most likely, the development of a leaky gut. Recent studies have also emphasized the essential role of the gut microbiome in these conditions. However, conflicting findings were found between one study and another investigation. Therefore, this paper aims to provide an overview of gut microbiome characteristics in adult Asians with obesity, T2D, and the combination of both.

Patients in both groups were treated with conventional sodium dimercaptopropanesulfonate, to which GDL was added in the observation group, while the control group was given the corresponding placebo treatment. Before and after treatment, liver stiffness was assessed, blood samples were collected for laboratory tests, and stool samples were collected for 16S rRNA sequencing. Supplementation with GDL significantly improved liver stiffness and non-invasive liver fibrosis modeling indicators, while alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, bile acid, platelets, hyaluronic acid and laminin levels were also significantly improved (p<0.05). Other parameters showed no significant changes. The results of intestinal microbial testing showed that the microbial diversity and composition of the patients in the observation group underwent significant optimization, in which the number of probiotics rose but the number of pathogenic and opportunistic pathogens declined and even basically returned to the normal range. GDL combined with conventional liver-protecting and copper-removing treatments can effectively improve patients' liver fibrosis-related indexes.

The sIgA secreted into the intestinal tract acts to prevent luminal pathogens and food antigens from penetrating across the intestinal epithelial barrier, thereby contributing to the suppression of infections and food allergies. Furthermore, it binds extensively to symbiotic bacteria, exerting a significant impact on the gut microbiota. The antigen recognition specificity of antibodies is determined by the amino acid sequence of the variable region. Therefore, the type of IgA repertoire influences the formation and maintenance of the gut microbiota and susceptibility to infection and food allergy. The initial repertoire of IgA is induced by the extensive colonization of intestinal bacteria during the weaning period and is maintained for an extended period. However, the relationship between the initial gut microbiota and IgA repertoire development has yet to be fully analyzed. In the present study, the weaning gut microbiota was disrupted with antibiotics, and the IgA repertoire was subsequently analyzed in young adulthood. The administration of antibiotics during the weaning period resulted in the suppression of somatic hypermutation in the variable regions of IgA expressed in the small intestine, as well as an impact on multivalent reactivity in IgA during early childhood. Additionally, disturbances in the weaning gut microbiota led to alterations in the microbiota structure of adolescent mice.

Given the potential health benefits of GOS in cats, we conducted a single-arm open-label study to evaluate the effects of a GOS-containing syrup on the gut microbiota and its metabolites in healthy cats. The study included 25 household cats and was conducted over 12 weeks. Each cat was fed 1.2 g of a GOS-containing syrup per day, equivalent to 0.5 g of GOS. Before the start of the study (week 0), during the 8-week intake period (weeks 4 and 8), and 4 weeks after the intake period (week 12), fecal microbiota, fecal organic acid and putrefactive product concentrations, fecal odor, and serum uremic toxin concentrations were assessed. The results showed that the levels of acetic acid-producing <i>Bifidobacteriaceae</i> significantly increased as a result of GOS intake. Additionally, <i>Peptostreptococcaceae</i> and <i>Eggerthellaceae</i> levels significantly decreased and increased, respectively, due to GOS intake.

This study aimed to explore the effects of long-term consumption of <i>Lacticaseibacillus paracasei</i> strain Shirota-fermented milk (LcFM) on body weight in the oldest old among nursing-home residents. In total, 118 participants in 21 nursing homes were recruited. Owing to its preliminary nature, randomization and blinding were not conducted, and subjects in the intervention (consuming LcFM daily for 12 months) and non-intervention groups were recruited separately from different nursing homes. Changes in body weight and the proportion of participants with ≥5% body-weight loss were assessed at 6 and 12 months. As intergroup discrepancies in care-needs levels were observed at baseline, a subgroup analysis by these levels was conducted to align baseline characteristics. In the mild care-needs level subgroup (long-term care level ≤2), the LcFM group had a significantly lower proportion of participants with ≥5% weight loss than the control group. Additionally, a subgroup analysis by BMI demonstrated that an effect of LcFM on body weight decline was observed only in the subgroup with a BMI <22 kg/m², which indicates malnutrition risk in older adults. In conclusion, long-term consumption of LcFM might reduce unintentional weight loss in the institutionalized oldest-old individuals who have a risk of malnutrition and have a mild care-needs level.
