Short chain fatty acids (SCFAs) being produced during fermentation of non-digestible polysaccharides are regulatory compounds with the potential to influence inflammatory, as well emotional state and cognition through gut–brain axis. We analyzed association between stool concentration SCFAs (acetic acid (C 2:0), propionic 3:0), isobutyric 4:0 i), butyric n), isovaleric 5:0 i) valeric isocaproic 6:0 caproic acid, n) heptanoic 7:0)) depressive symptoms among women looked for confounders...

During the postmenopausal period, risk of cardiovascular diseases is increased in many obese women and associated with a worse cardiometabolic profile sub-chronic low-grade systemic inflammation caused by gut barrier permeability dysfunction. Here, we tested whether administration two different dosages multispecies probiotic Ecologic® Barrier influenced biochemical parameters lipopolysaccharide levels, latter used as marker women. A total 81 Caucasian participated trial. The subjects...

Obesity in the postmenopausal period is associated with an increased risk of cardiovascular diseases women. One key drivers endothelial dysfunction; thus, this also a crucial point for studies on new therapeutic methods cardioprotective properties. The aim current study was to evaluate effect two doses multispecies probiotic Ecologic® Barrier supplement functional (primary endpoint) and biochemical parameters (secondary dysfunction obese women 12-week randomized, placebo-controlled clinical...

This comprehensive review delineates the extensive roles of Akkermansia muciniphila in various health domains, spanning from metabolic and inflammatory diseases to neurodegenerative disorders. A. muciniphila, known for its ability reside mucous layer intestine, plays a pivotal role maintaining gut integrity interacting with host processes. Its influence extends modulating immune responses potentially easing symptoms across several non-communicable diseases, including obesity, diabetes, bowel...

Current treatment of major depressive disorder (MDD) often does not achieve full remission symptoms. Therefore, new forms and/or adjunct therapy are needed. Evidence has confirmed the modulation gut-brain-microbiota axis as a promising approach in MDD patients. The overall purpose SANGUT study-a 12-week, randomized, double-blind, and placebo-controlled Study Evaluating Effect Probiotic Supplementation on Mental Status, Inflammation, Intestinal Barrier Major Depressive Disorder Patients Using...

The intestinal barrier plays an important role in the defense against infections, and nutritional, endocrine, immune functions. gut microbiota playing development of gastrointestinal tract can impact permeability immunity during early life, but data concerning this problem are scarce.We analyzed fecal samples (101 total) collected longitudinally over 24 months from 21 newborns to investigate whether markers small paracellular (zonulin) system (calprotectin) linked microbiota. results were...

Probiotics are known to regulate host metabolism. In randomized controlled trial we aimed assess whether interventions with probiotic containing following strains: Bifidobacterium bifidum W23, lactis W51, W52, Lactobacillus acidophilus W37, Levilactobacillus brevis W63, Lacticaseibacillus casei W56, Ligilactobacillus salivarius W24, Lactococcus W19, and W58 affect gut microbiota promote metabolic effects. By 16S rRNA sequencing analyzed the fecal of 56 obese, postmenopausal women into three...

Short-chain fatty acids (SCFAs) are important metabolites of the gut microbiota. The aim is to analyze influence perinatal factors, which can affect microbiota, on concentrations fecal SCFAs over first two years life. Gas chromatography was used SCFA in a total 456 samples from 86 children. Total increased until 12 months and stabilized after that. Antibiotic treatment during pregnancy associated with an increase acetic acid, propionic acid meconium decrease same at 6 months. Butyric...

Intestinal microbiota play an important role in the pathogenesis of surgical site infections (SSIs) and other surgery-related complications (SRCs). Probiotics synbiotics were found to lower risk adverse events. We systematically reviewed approach based on administration probiotics diminish SSIs/SRCs rates patients undergoing various treatments determine mechanisms responsible for their effectiveness. A systematic literature search PubMed/MEDLINE/Cochrane Central Register Controlled Trials...

Accumulating evidence indicates the potential effect of microbiota on pathogenesis and course schizophrenia. However, effects olanzapine, second-generation antipsychotics, gut have not been investigated in humans. This study aimed to analyze fecal schizophrenia patients treated with olanzapine during six weeks their hospital stay. After a seven-day washout from all psychotropic medications, compositions were evaluated at baseline after hospitalization using 16S rRNA sequencing. The was...

Background Sodium bicarbonate (SB) has been proposed as an ergogenic aid, it improves high-intensity and resistance exercise performance. However, no studies have yet investigated SB application in CrossFit. This study examined the effects of chronic, progressive-dose ingestion on CrossFit-like performance aerobic capacity. Methods In a randomized, double-blind, cross-over trial, 21 CrossFit-trained participants were randomly allocated to 2 groups underwent trials separated by 14-day washout...
