Abstract
Gut dysbiosis refers to an imbalance in gut microbiota composition and function. Opuntia ficus-indica extract has been shown to modulate gut microbiota by improving SCFA production in vivo and gastrointestinal discomfort (GD) in humans. The aim of this study was to demonstrate the efficacy of OdiliaTM on gastrointestinal health by changing the microbial diversity of species involved in inflammation, immunity, oxidation, and the brain-gut-muscle axis. A randomized, double-blind clinical trial was conducted in 80 adults with gut dysbiosis. The intervention consisted of a 300 mg daily intake of OdiliaTM (n = 40) or maltodextrin as a placebo (n = 40), administered for 8 weeks. Intervention effect was evaluated using 16S metagenomics and GIQLI/GSAS scores at baseline, at 4 and 8 weeks. Eight weeks of OdiliaTM supplementation positively modulates gut microbiota composition with a significant reduction in the Firmicutes to Bacteroidetes ratio (p = 0.0012). Relative abundances of beneficial bacteria (Bacteroides and Clostridium_XIVa) were significantly increased (p < 0.001), in contrast to a significant reduction in pro-inflammatory bacteria (p < 0.001). Accordingly, GIQLI and GSAS scores revealed successful improvement in GD. OdiliaTM may represent an effective and well-tolerated treatment in subjects with gut dysbiosis.

Abstract
The role of the microbiota in health and disease has long been recognized and, so far, the cutaneous microbiota in humans has been widely investigated. The research regarded mainly the microbiota variations between body districts and disease skin states (i.e., atopic dermatitis, psoriasis, acne). In fact, relatively little information is available about the composition of the healthy skin microbiota. The cosmetic industry is especially interested in developing products that maintain and/or improve a healthy skin microbiota. Therefore, in the present work, the authors chose to investigate in detail the structure and composition of the basal bacterial community of the face. Ninety-six cheek samples (48 women and 48 men) were collected in the same season and the same location in central northern Italy. Bacterial DNA was extracted, the 16S rDNA gene was amplified by PCR, the obtained amplicons were subjected to next generation sequencing. The principal members of the community were identified at the genus level, and statistical analyses showed significant variations between the two sexes. This study identified abundant members of the facial skin microbiota that were rarely reported before in the literature and demonstrated the differences between male and female microbiota in terms of both community structure and composition.
