Behavioural, cognitive, and neurophysiological effects of a synbiotic supplementation enriched with pigmented corn extract or cornstarch in drug-naïve children with attention-deficit hyperactivity disorder: a randomised, double-blind, comparison-controlled clinical trial.

Background & Aims: Considerable interest has been recently given to the potential role of the gut-brain axis (GBA) -a two-way communication network between the gut microbiota and the central nervous system- in the pathogenesis of attention-deficit hyperactivity disorder (ADHD), suggesting the potential usefulness of probiotic and synbiotic supplementations. In light of the limited available evidence, synbiotic efficacy in ADHD children not taking medications should be clarified. This study aimed to investigate the efficacy of a synbiotic dietary supplementation on fatty acids levels as well as on microbiota composition, behaviour, cognition, and brain function in children with ADHD.

Use of ICD-9-CM coding for identifying antibiotic prescriptions during hospitalization: a Delphi consensus model.

A Delphi consensus-seeking procedure was conducted to validate a list of ICD-9-CM codes that could help identify hospital admissions in which antimicrobials are more likely to be prescribed. The panel agreed to include 2967 codes out of 16229 (18.28%).

The Effects of Animal, Collection Time, and Interval on the Microbiota Structure, Metabolism, and Degradative Potential of Rumen Fluid Inoculum Collected by Esophageal Probe from Hay-Fed Cows.

Rumen fluid (RF) is the greatest source of uncontrolled inter-assay variations in in vitro digestibility tests. This study aimed to investigate the effect of donor cow (DC) individual variability, time relative to feeding, and weekly sampling intervals on RF microbiota structure and metabolism, and on its degradative capacity expressed as enzymatic activity (EA). RF was collected using an esophageal probe from 4 Holstein hay-fed DCs before feeding, and 4 and 8 h post-feeding, over 3 days with one-week intervals, for a total of 3 weeks.

Staphylococcus aureus and methicillin-resistant staphylococci and mammaliicocci in the bulk tank milk of dairy cows from a livestock-dense area in northern Italy.

Staphylococcus aureus is the main etiologic agent of contagious dairy cow mastitis, while non-aureus staphylococci and mammaliicocci (NASM) are the bacteria most frequently isolated from milk. Beyond their impact on animal health, NASM can harbor antimicrobial resistance (AMR) genes with potential for bidirectional transfer with S. aureus, and methicillin-resistant (MR) staphylococci (MRS) can raise significant One Health concerns.
