This comprehensive approach can improve our understanding of A. muciniphila response to physical exercise and highlight gaps in the literature, providing valuable insights for future microbiome research. Four databases (Web of Science, PubMed, Scopus, and Sports Discuss) were searched in the literature. Quality assessment was conducted independently and in duplicate using two risk-of-bias tools (Downs and Black for human studies and SYRCLE's risk of bias for animal studies). 3,901 studies were identified, with thirteen human studies and nine animal studies included after screening. Of the thirteen human studies analysed, five (38.5%) were cross-sectional, seven (53.8%) were longitudinal/experimental, and one (7.7%) was a case study. These studies included 522 participants, among whom 157 were athletes, such as rugby players, marathon runners, triathletes, and skiers. Six studies reported an increase in A. muciniphila, five showed a decrease, and two found no significant differences. Regarding interventions, two studies used a combination of moderate-intensity strength and aerobic training, while seven used low to moderate-intensity aerobic exercises. In the nine rodent studies, eight (88.9%) were conducted on mice and one (11.1%) on rats, with all being experimental. These studies involved 310 animals. Eight studies reported a substantial increase in A. muciniphila, while one found no differences. Among these, eight employed moderate-intensity aerobic exercises as the intervention, and one utilised low-to-moderate-intensity strength training. The studies summarised in this review indicate that the impact of various physical exercise protocols on A. muciniphila abundance in humans remains controversial. However, rodent studies provide strong evidence that aerobic exercise increases A. muciniphila abundance in faecal pellets of both healthy and diseased models.</p>","PeriodicalId":8834,"journal":{"name":"Beneficial microbes","volume":" ","pages":"565-587"},"PeriodicalIF":3.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the potential influence of the microbiome on infant sleep, this systematic review and meta-analysis aimed to determine the effect of biotic supplementation on sleep behaviours in full-term infants aged 0-12 months. In June 2023, we searched seven databases for randomised controlled trials (RCTs) of biotic supplementation intervention studies using synonymous terms for 'infant' AND 'biotic' AND 'sleep' (PROSPERO registration ID: CRD42022358822). Title/abstracts and the full texts were independently screened. Data on infant sleep and settling behaviour outcomes, reported adverse/side effects, and co-morbid conditions were extracted for analysis. Using the modified Cochrane Collaboration tool, two independent reviewers judged the risk of bias. Meta-analyses were conducted using RevMan5. Our search yielded 453 unique studies and 23 RCTs are included in this review. Probiotic supplementation was the most common biotic supplementation (provided in 53% of studies), while 28% and 19% offered prebiotic and synbiotic supplementation, respectively. Sleep duration was the most common (95%) reported outcome for probiotics. No significant differences were reported in sleep duration during the 1st to 4th week of probiotic supplementation. However, in the 5th week of probiotic supplementation, infants who received placebo slept significantly longer (MD = -35.17 min, 95% CI [-69.72, -0.62]), suggesting a borderline significance that is clinically relevant. There were limited studies and timeframe alignment to analyse prebiotics, synbiotics, post-biotics, and para-probiotics effects on infant sleep duration. The study suggests probiotic supplementation does not increase infant sleep duration within the first 4 postpartum weeks and may contribute to reduced sleep duration in the fifth week.

Therefore, we tested an improved diet-based nutritional interventions to improve the childhood obesity and its gut microbiota. Thirty obese children received a 12-week intervention with the adjust-energy-restricted dietary pattern (A-CRD). Body composition was measured by bioelectrical impedance (Inbody S10) and faecal microbes were profiled by sequencing 16S rRNA. Compared to the NTB group (at 0 week), the NTA group (at 12 weeks) had a significantly greater decrease in body weight, body mass index (BMI) and percent body fat (PBF) ( P < 0.001, respectively), whereas skeletal muscle mass (SMM) and fat free mass (FFM) were not statistically significantly different ( P > 0.05). The gut microbiota was found significantly different between the NTB and NTA groups based on alpha and beta diversity. Bifidobacterium, Blautia, and Streptococcus was significantly increased, whereas Bacteroides and Megamonas was significantly decreased in the NTA group ( P < 0.05, respectively). Meanwhile, NTA group significantly increased the ability to produce short-chain fatty acids (SCFAs; e.g. acetic acid/total dietary energy) and changed he predictive metabolic functional features of the microbiota communities ( P < 0.05, respectively) than the NTB group. In conclusion, A-CRD can significantly improve childhood obesity, and the underlying mechanism may be its effect on gut microbiota and metabolism.

A retrospective analysis was conducted on 581 elderly people aged 65-92 years from the Nakanojo Study, with the addition of a 5-year prospective analysis on 240 elderlies. Subjects were arbitrarily grouped on the basis of questionnaire estimates of fermented milk products intake (<3 or ≥3 days/week) and pedometer/accelerometer-determined patterns of physical activity (<7,000 or ≥7,000 steps/day). After adjustment for potential confounders, the retrospective study showed that the group consuming fermented milk products ≥3 days/week showed significantly faster walking speeds than the <3 days/week group. The group taking ≥7,000 steps/day had a significantly faster walking speed than the group taking <7,000 steps/day. Those who did both walked the fastest, indicating an additive effect. Adding protein or energy intake as a covariate to the potential confounders found a correlation between the intake of fermented milk products and walking speed, suggesting that the effect of fermented milk products consumption is independent of nutritional intake status, due to the beneficial properties of bacteria included in fermented milk. The 5-year prospective study confirmed a clear relationship between the frequency of consumption of fermented milk products and the suppression of preferred walking speed decline.

In this review, we aimed to assess the efficacy of probiotics in preventing or ameliorating disruptions in microbiome composition and function induced by antibiotic treatment. We searched Medline, Embase, and CENTRAL for randomised controlled and non-randomised trials. Participants were individuals of any age who were on systemic antibiotics with a low risk of baseline dysbiosis. The intervention consisted of probiotics during or after antibiotic treatment, compared to placebo, alternative interventions, or no intervention. Outcomes included microbiome composition and diversity analysed using high-throughput molecular methods, alongside microbial function and resistome assessments. Seven studies, reported in eight papers, were reviewed. One study showed probiotics counteracting antibiotic-induced diversity changes, another showed exacerbation of these changes, and four others showed no effect. Effects on taxa abundance ranged from mitigating dysbiosis to selective modulation, no effect, or delayed recovery. One study observed no impact on the resistome, while another reported an increase in antibiotic resistance genes. In conclusion, heterogeneous results preclude a definitive conclusion on the effectiveness of any specific probiotic in restoring antibiotic-exposed microbiomes. For a clearer understanding, future research should be more standardised and long-term, employing advanced methods, such as 16S rRNA gene sequencing and metagenomic sequencing. These studies should strive to include larger, diverse populations to enhance generalisability and clearly define what constitutes a healthy microbiome.

GABA is a non-protein amino acid widely distributed in nature and produced in animals, plants, and microorganisms. However, the best known role of GABA is its function as the major inhibitory neurotransmitter of the central nervous system. Preclinical and clinical evidence suggests that the GABAergic system has a relevant role in mental health disorders, such as anxiety and major depression. The modulation of the GABAergic system has been suggested as a potential strategy for treatment, one such mechanism of modulation is the influence of the microbiota-gut-brain axis through probiotic treatments. The present study was designed to investigate the in vivo probiotic potential of LPB145, a Lactiplantibacillus strain previously characterised as a GABA-producing potentially probiotic strain. Therefore, we evaluated the behavioural effects of chronic oral administration of LPB145 on rats' anxiety- and depression-like behaviours, using the elevated plus maze, open field, and the forced swimming test. The impact of LPB145 strain treatment on the gut microbiota structure and diversity was assessed to discern a possible mechanism of action of the LPB145 treatment through the microbiota-gut-brain axis. Our results showed that LPB145 administration induced an antidepressive-like behaviour without changes in locomotor activity. In contrast, the treatment did not modify the experimental anxiety. The structure and diversity of the intestinal microbiota remained unaffected by the treatment when compared to the control. However, specific clades that could be implicated in the behavioural changes did show differences in their relative abundance.

Tissues staining, enzyme-linked immunosorbent assay (ELISA) was performed to detect changes in histopathology and inflammatory cytokines, respectively. Moreover, intestinal permeability was evaluated by the level of dextran-fluorescein isothiocyanate (Dx-FITC) in serum and tight junction protein in the colon. Changes in the composition of the gut microbiota were assessed by 16S rRNA sequencing. Alcohol consumption induced liver damage in mice with significantly increased levels of triglycerides (TG), aspartate aminotransferase (AST), alanine transaminase (ALT), and inflammatory cytokines. Moreover, alcohol further induced the increase of intestinal permeability and disruption of gut microbiota in mice, with an increase in the relative abundance of potentially pathogenic bacteria Enterococcus, Parabacteroides, and Alistipes. LRa05 intervention significantly attenuated alcohol-induced liver injury by reducing the contents of TG, ALT, and AST, and suppressing the inflammatory responses. Meanwhile, by stimulating the expression of ZO-1, Occludin, and Claudin in the colon tissue, LRa05 additionally strengthened the intestine barrier function. Furthermore, gut microbiota analysis suggested that LRa05 partially ameliorated gut microbiota disorders in ALD mice and up-regulated the abundance of Desulfovibrio and Akkermansia, which were negatively correlated with the indicators of ALD progression.
