Meta-Analysis Review
BACKGROUND
This paper aimed to examine the effects of probiotics on eight factors in overweight or obese children by meta-analysis, namely, body mass index (BMI), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), adiponectin, leptin and tumor necrosis factor-α (TNF-α) and summarize the mechanisms of action of probiotics based on the existing researches.
METHODS
Six databases (PubMed, Web of Science, Embase, Cochrane Library, SinoMed and CNKI) were searched until March 2023. Review Manager 5.4 was used for meta-analysis. The data were analysed using weighted mean differences (WMDs) or standardized mean differences (SMDs) under a fixed effect model or random effect model to observe the effects of probiotic administration on the included indicators.
RESULTS
Four publications with a total of 206 overweight or obesity children were included. According to the meta-analysis, probiotics were able to significantly decrease the levels of HDL-C (MD, 0.06; 95% CI 0.03, 0.09; P = 0.0001), LDL-C (MD, - 0.06; 95% CI - 0.12, - 0.00; P = 0.04), adiponectin (MD, 1.39; 95% CI 1.19, 1.59; P < 0.00001), leptin (MD, - 2.72; 95% CI - 2.9, - 2.54; P < 0.00001) and TNF-α (MD, - 4.91; 95% CI - 7.15, - 2.67; P < 0.0001) compared to those in the placebo group. Still, for BMI, the palcebo group seemed to be better than the probiotic group (MD, 0.85; 95% CI 0.04, 1.66; P = 0.04). TC (MD, - 0.05; 95% CI - 0.12, 0.02; P = 0.14) and TG (MD, - 0.16; 95% CI - 0.36, 0.05; P = 0.14) were not different between two groups.
CONCLUSIONS
This review drew that probiotics might act as a role in regulating HDL-C, LDL-C, adiponectin, leptin and TNF-α in overweight or obesity children. Additionally, our systematic review yielded that probiotics might regulate lipid metabolism and improve obese associated symptoms by some paths. This meta-analysis has been registered at PROSPERO with ID: CRD42023408359.

Review
Hypertension is an increasingly pressing public health concern across the globe. It can be triggered by a variety of factors such as age and diet, as well as the stress of modern life. The traditional treatment of hypertension includes calcium ion blockers, angiotensin II receptor inhibitors and β-receptor blockers, but these drugs have at least some side effects. Recent studies have revealed that intestinal flora plays a vital role in maintaining and promoting human health. This is due to the type and amount of probiotics present in the flora. Probiotics can reduce hypertension symptoms through four mechanisms: regulating vascular oxidative stress, producing short-chain fatty acids, restoring endothelial cell function, and reducing inflammation. It has been reported that certain functional foods, using probiotics as their raw material, can modify the composition of intestinal flora, thus regulating hypertension symptoms. Consequently, utilizing the probiotic function of probiotics in conjunction with the properties of functional foods to treat hypertension is a novel, side-effect-free treatment method. This study seeks to summarize the various factors that contribute to hypertension, the mechanism of probiotics in mitigating hypertension, and the fermented functional foods with probiotic strains, in order to provide a basis for the development of functional foods which utilize probiotics as their raw material and may have the potential to reduce hypertension.

Meta-Analysis
BACKGROUND
Probiotics are often used to prevent antibiotic-induced low-diversity dysbiosis, however their effect is not yet sufficiently summarized in this regard. We aimed to investigate the effects of concurrent probiotic supplementation on gut microbiome composition during antibiotic therapy.
METHODS
We performed a systematic review and meta-analysis of randomized controlled trials reporting the differences in gut microbiome diversity between patients on antibiotic therapy with and without concomitant probiotic supplementation. The systematic search was performed in three databases (MEDLINE (via PubMed), Embase, and Cochrane Central Register of Controlled Trials (CENTRAL)) without filters on 15 October 2021. A random-effects model was used to estimate pooled mean differences (MD) with 95% confidence intervals (CI). This review was registered on PROSPERO (CRD42021282983).
RESULTS
Of 11,769 identified articles, 15 were eligible in the systematic review and 5 in the meta-analyses. Quantitative data synthesis for Shannon (MD = 0.23, 95% CI: [(-)0.06-0.51]), Chao1 (MD = 11.59 [(-)18.42-41.60]) and observed OTUs (operational taxonomic unit) (MD = 17.15 [(-)9.43-43.73]) diversity indices revealed no significant difference between probiotic supplemented and control groups. Lacking data prevented meta-analyzing other diversity indices; however, most of the included studies reported no difference in the other reported α- and ß-diversity indices between the groups. Changes in the taxonomic composition varied across the eligible studies but tended to be similar in both groups. However, they showed a potential tendency to restore baseline levels in both groups after 3-8 weeks. This is the first meta-analysis and the most comprehensive review of the topic to date using high quality methods. The limited number of studies and low sample sizes are the main limitations of our study. Moreover, there was high variability across the studies regarding the indication of antibiotic therapy and the type, dose, and duration of antimicrobials and probiotics.
CONCLUSIONS
Our results showed that probiotic supplementation during antibiotic therapy was not found to be influential on gut microbiome diversity indices. Defining appropriate microbiome diversity indices, their standard ranges, and their clinical relevance would be crucial.

Meta-Analysis Review
UNLABELLED
Recent studies have demonstrated the effect of probiotics, prebiotics, and synbiotics on adiponectin and leptin levels; however, those findings remain contested. The present study aimed to explore the impact of probiotics/synbiotics on appetite-regulating hormones and the desire to eat.
METHODS
A systematic review was conducted by searching the Medline (PubMed) and Scopus databases from inception to December 2021, using relevant keywords and MeSH terms, and appropriate randomized controlled trials (RCTs) were extracted. The standardized mean differences (SMD) and 95% confidence intervals (95%CIs) were calculated as part of the meta-analysis using a random-effect model to determine the mean effect sizes. Analysis of Galbraith plots and the Cochrane Chi-squared test were conducted to examine heterogeneity.
RESULTS
Meta-analysis of data from a total of 26 RCTs (n = 1536) showed a significant decrease in serum/plasma leptin concentration following probiotic/synbiotic supplementation (SMD: -0.38, 95%CI= -0.638, -0.124); P-value= 0.004; I= 69.4%; P heterogeneity < 0.001). The leptin level decrease from probiotic/synbiotic supplementation was higher in patients with NAFLD than those with overweight/obesity or type 2 diabetes mellitus/ metabolic syndrome/ prediabetes. Probiotic/synbiotic supplementation was associated with a trending increase in adiponectin levels, stronger in patients with type 2 diabetes mellitus, metabolic syndrome, and prediabetes (SMD: 0.25, 95%CI= 0.04, 0.46) µg/mL; P-value= 0.021; I = 16.8%; P heterogeneity= 0.30). Additionally, supplementation with probiotic/synbiotic was linked to a slight increase in desire to eat (SMD: 0.34, 95%CI= 0.03, 0.66) P-value = 0.030; I = 39.4%; P heterogeneity= 0.16).
CONCLUSION
Our meta-analysis indicates a favorable impact of probiotic/synbiotic supplementation on regulating leptin and adiponectin secretion.

Review
In modern society, where new diseases and viruses are constantly emerging, drugs are still the most important means of resistance. However, adverse effects and diminished efficacy remain the leading cause of treatment failure and a major determinant of impaired health-related quality of life for patients. Clinical studies have shown that the disturbance of the gut microbial structure plays a crucial role in the toxic and side effects of drugs. It is well known that probiotics have the ability to maintain the balance of intestinal microecology, which implies their potential as an adjunct to prevent and alleviate the adverse reactions of drugs and to make medicines play a better role. In addition, in the past decade, probiotics have been found to have excellent prevention and alleviation effects in drug toxicity side effects, such as liver injury. In this review, we summarize the development history of probiotics, discuss the impact on drug side effects of probiotics, and propose the underlying mechanisms. Probiotics will be a new star in the world of complementary medicine.

Achieving healthy aging and providing protection from aging-related diseases is a major global concern. Probiotics, are a safer and more natural alternative. Moreover, identifying novel probiotics can help develop a new therapeutic approach and may help in personalized probiotic-formulations for individual's unique gut microbiome. In this study, we evaluated the benefits of our novel probiotic strains in promoting healthy aging and whether they protect against Amyloid β toxicity of Alzheimer's disease. Henceforth, we analyzed the impact of four different probiotics (Lactobacillus paracasei HII01, L. rhamnosus, L. reuteri, L. salivarius) on the lifespan extension of Caenorhabditis elegans model. Our results determine that L. paracasei HII01 provided the most positive effect on longevity and antiaging effects on C. elegans. The qPCR data and mutant-based studies indicated that L. paracasei HII01-mediated lifespan extension could be modulated by DAF-16 mediated pathway. The probiotic strains also protected the worms from the toxicity induced by β-Amyloid-expressing (Aβ) transgenic C. elegans strains, and L. paracasei HII01 provided the most significant protection. Overall, identifying novel probiotics is an important area of research that can improve health outcomes. Our study showed that L. paracasei HII01 could be considered a dietary supplement for providing healthy aging and preventing aging-related diseases.

Meta-Analysis Review
BACKGROUND
The effect of probiotic therapy on bacterial vaginosis (BV) is controversial. We conducted a meta-analysis of the efficacy and safety associated with probiotic treatment for BV.
METHODS
We searched multiple databases covering up to 1 March 2018. Studies published as blinded randomized controlled trials (RCTs), comparing treatment using probiotic versus active or placebo control in BV patients were included, with at least one-month follow-up. Random effects model and trial sequential analysis (TSA) were applied.
RESULTS
Ten studies ( = 2321) were included. Compared with placebo, the probiotics-only therapy resulted in a beneficial outcome both in clinical cure rate at the 30th day (risk ratio, RR = 2.57; 95% confidential interval, 95% CI: 1.96 to 3.37), and Nugent score (mean difference, MD = -2.71; 95% CI: 3.41 to -2.00). This effect decreased but remained significant after eight weeks. Probiotics-post-antibiotics therapy had a decreased effect only for a short term and possibly among studies with a mostly black study population. No extra adverse events were observed. The TSA suggested a larger sample size for effective evaluation of the probiotics as a supplementary remedy.
CONCLUSIONS
Probiotic regimes are safe and may exhibit a short-term and long-term beneficial effect for BV treatment. The ethnic-specific result for the probiotic used after antibiotics is worthy of further study.

Meta-Analysis
OBJECTIVE
To evaluate the effectiveness of probiotic supplementation on upper respiratory tract infection (URTI) and inflammatory markers in elite athletes.
DATA SOURCES
We searched the PubMed, EBSCOhost, Scopus, and Web of Science databases using the following terms: probiotic OR probiotics AND exercise OR sport OR athletes AND URTI OR respiratory infection OR URTIs OR inflammation OR inflammatory OR cytokines.
STUDY SELECTION
We screened the titles and abstracts of 2498 articles using our inclusion criteria. A total of 14 articles were selected for further analysis.
DATA EXTRACTION
For each study, 2 independent reviewers extracted the study design, participant characteristics, inclusion and exclusion criteria, intervention characteristics, outcome measures, and main results.
DATA SYNTHESIS
We did not observe an effect of probiotic supplementation on the number of days of illness or the mean number or duration of URTI episodes but did note an effect of probiotic supplementation on the total symptom severity score (-0.65; 95% CI = -1.05, -0.25; P = .02). Lower levels of interleukin 6 (-2.52 pg/mL; 95% CI = -4.39, -0.66 pg/mL; P = .002) and tumor necrosis factor α (-2.31 pg/mL; 95% CI = -4.12, -0.51 pg/mL; P = .01) were also reported after supplementation.
CONCLUSIONS
This meta-analysis provides evidence that probiotic supplementation, especially among professional athletes, is an effective way to decrease the total URTI symptom severity score. In addition, probiotic supplementation may decrease interleukin 6 and tumor necrosis factor α levels. More studies involving larger groups are needed to better assess this effect. The optimal timing, duration, composition, and dose of such supplementation need to be determined.

Review
Probiotics represent viable microorganisms which are found within the normal gut microbiota, that exert strain-specific benefits in the management of several gastrointestinal disorders in children, including acute gastroenteritis. This review aims to evaluate the pathogen-specific role of probiotic supplementation in childhood diarrhea. A search of scientific databases was conducted to identify studies which investigated efficacy of probiotics and synbiotics in influencing outcome of acute gastroenteritis of known etiology. We identified 32 studies, most of which analyzed impact of probiotic supplementation in rotavirus gastroenteritis, while a very limited number of these conducted a separate analysis on bacterial diarrhea. (), and still remain the most researched strains, with a proven role in decreasing diarrhea and hospitalization duration, especially in the setting of rotavirus infection. Combined products containing at least one of the aforementioned strains also performed similarly and might also influence rotavirus fecal shedding. Rotavirus immunization status has also been proposed as a significant influencing factor of probiotic use impact. The paucity of research focusing on bacterial etiologies, as well as of clinical trials conducted within ambulatory care units leaves room for further research on the matter, which needs to include larger cohort studies.

BACKGROUND
To examine the incidence of diarrhea in severe and critical coronavirus disease 2019 (COVID-19) patients, and to observe the efficacy and prognosis of probiotic use in such patients.
METHODS
A retrospective study was conducted to investigate the symptoms and incidence of diarrhea in 156 cases of COVID-19 confirmed by the First Affiliated Hospital of Zhengzhou University and the Xinyang Fifth People's Hospital, China. A total of 58 cases of severe and critical COVID-19 were identified and divided into the treatment group or the control group. The control group was given standard treatment according to the Protocols for Diagnosis and Treatment of COVID-19: Prevention, Control, Diagnosis and Management. Patients in the treatment group were administered oral probiotics as well as the standard treatment. The 2 groups were compared in terms of nutritional status (serum albumin), improvement of diarrhea symptoms, changes in inflammatory condition [procalcitonin (PCT) and C-reactive protein (CRP)], the time taken to register a negative result for respiratory tract pathogens on the nucleic acid test, and changes to white blood cell and lymphocyte cell counts.
RESULTS
In this study cohort, diarrhea was detected in 15.38% (24/156) of COVID-19 patients. The incidence of diarrhea in patients with mild and moderate COVID-19 was approximately 8.16% (8/98), and the incidence of diarrhea in severe and critically ill patients was approximately 27.59% (16/58). In patients with severe and critical COVID-19, probiotic treatment obviously shortened the duration of diarrhea. Furthermore, compared with the control group, patients treated with probiotics showed a significantly reduced time to achieving a negative nucleic acid test and the inflammation indexes including PCT and CRP were significantly reduced (P<0.05).
CONCLUSIONS
The incidence of diarrhea in severe and critically ill COVID-19 patients was significantly higher than that in patients with mild and moderate COVID-19. Probiotics may have a good supporting role in the treatment of patients with COVID-19 and its early application is recommended.
