TLDR
The metagenomically characterized the murine and human mucosal-associated gastrointestinal microbiome and found it to only partially correlate with stool microbiome, indicating that empiric probiotics supplementation may be limited in universally and persistently impacting the gut mucosa.

Gut microbiota in human metabolic health and disease.

TL;DR: How the gut microbiota and derived microbial compounds may contribute to human metabolic health and to the pathogenesis of common metabolic diseases are discussed, and examples of microbiota-targeted interventions aiming to optimize metabolic health are highlighted.
Journal ArticleDOI

The gut microbiota at the intersection of diet and human health

TL;DR: Diet is a key component of the relationship between humans and their microbial residents; gut microbes use ingested nutrients for fundamental biological processes, and the metabolic outputs of those processes may have important impacts on human physiology.

Modulation of Fecal Clostridiales Bacteria and Butyrate by Probiotic Intervention with Lactobacillus paracasei DG Varies among Healthy Adults

TL;DR: The intake of L. paracasei DG increased the Blautia:Coprococcus ratio, which, according to the literature, can potentially confer a health benefit on the host, which seems to strictly depend on the initial characteristics of the intestinal microbial ecosystem.
Journal ArticleDOI

Differences in Composition and Mucosal Adhesion of Bifidobacteria Isolated from Healthy Adults and Healthy Seniors

TL;DR: The results indicate that the mucosal adhesive properties of the human Bifidobacterium flora were reduced with the aging of the host, which may explain the decrease in b ifidobacteria levels in the intestinal microflora of aging people.

Functional Dynamics of the Gut Microbiome in Elderly People during Probiotic Consumption

TL;DR: The results provide evidence for the discrete functional effects imparted by a specific single-organism probiotic and challenge the prevailing notion that probiotics substantially modify the resident microbiota within nondiseased individuals in an appreciable fashion.

Effect of Lactobacillus on body weight and body fat in overweight subjects: a systematic review of randomized controlled clinical trials.

TL;DR: Results suggest that the beneficial effects are strain dependent and can highlight that Lactobacillus plantarum and LactOBacillus rhamnosus when combined with a hypocaloric diet, and multiple species of Lactoblacillus.

Using probiotics in clinical practice: Where are we now? A review of existing meta-analyses.

TL;DR: This study provides a critical overview of the current meta-analyses that have evaluated the efficacy of probiotics in physiologic and pathological conditions, such as metabolic disease, antibiotic-associated and Clostridium difficile-associated diarrhea, IBS, constipation, IBD, chemotherapy- associated diarrhea, respiratory tract infection, ventilator-associated pneumonia, NAFLD and necrotising enterocolitis in premature infants.
