Article Abstract
Background And Aims: Several studies reported the effect of COVID-19 on inducing gut dysbiosis, which is also correlated with disease severity. This study aims to investigate the effect of a nutraceutical formula on the shift of microbiota profiles and, secondly, on the clinical-pathological parameters of acute and post-acute COVID-19 patients.
Methods: In this randomised, double-blind, placebo-controlled trial conducted at National Institute for Infectious diseases (INMI) Lazzaro Spallanzani (Italy), 52 patients were randomly assigned (1:1) to receive a multistrain synbiotic formula (Kebirah) or placebo orally for 35 days at COVID-19 diagnosis. Health professionals, investigators, and patients were masked to group assignments. The V3-V4 hypervariable region of 16S rRNA gene sequencing was employed to study the gut microbiota composition in the two groups.
Results: Supplementation with Kebirah prevented the decrease in the Shannon diversity index of gut microbiota, which was instead observed in patients receiving the placebo. In addition, decreases in lymphocyte count and haemoglobin levels were observed only in the placebo group and not in the treated group, which was also characterised by an amelioration of the gut microbial profile, with an enrichment in beneficial bacteria and a preservation of species diversity.
Conclusions: Our data suggest that modulating the gut microbiota in acute disease through administration of a specific symbiotic formula could be a useful strategy in the frame of SARS-CoV-2 infections.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a condition that results from metabolic disorders. In addition to genetic factors, irregular and high-energy diets may also significantly contribute to its pathogenesis. Dietary habits can profoundly alter the composition of gut microbiota and metabolites.

In pig production, weaning is a critical period where piglets face several environmental stressors. This transition leads to a significant growth reduction and can result in digestive disorders, including diarrhea. To formulate a feed that meets zinc (Zn) and copper (Cu) requirements during the weaning period while minimizing their release into the environment, it became evident that a more bioavailable micro-mineral supplement is necessary.

Purpose Of The Review: This review aimed to summarize current evidence on the effectiveness of medical nutrition therapy (MNT) in the management of obesity and endometriosis, with a focus on dietary patterns such as the Mediterranean and Ketogenic diets, as well as nutritional supplementation. Additionally, it highlights the central role of the clinical nutritionist in implementing individualized, evidence-based interventions within multidisciplinary care.
Recent Findings: Although the literature reports the existence of an inverse relationship between risk of endometriosis and body mass index, clinical evidence jointly reports that a condition of obesity is associated with greater disease severity.

The inhibitory effects of Lactiplantibacillus plantarum on inflammatory responses are known, but its action mechanisms in oxidative stress, immunomodulation, and intestinal homeostasis remain of interest. Accordingly, we investigated the protective effects of Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2) against sodium dextran sulfate (DSS)-induced colitis in mice as well as elucidated its impact on inflammation, oxidative stress, and intestinal microbiota.
