Understanding Of Probiotics Research Articles

Meta-analysis to predict the effects of probiotics on meat quality of broiler.

The demand for chicken meat has surged globally due to its status as a primary protein source in human diets. However, ensuring high-quality meat products has become an increasingly important subject to consumers. In this study, 21 articles from PubMed and Web of Science databases published between 2005 and 2023 were examined to assess the influence of probiotic supplementation on broiler meat quality. The meta-analysis revealed significant findings across various meat quality parameters. Specifically, probiotics were found to significantly affect meat colour parameters, including redness, yellowness, and lightness, in both breast and thigh meat samples. Moreover, significant differences were observed in parameters such as water-holding capacity (p < 0.001), cook loss (p = 0.047), and shear force (p = 0.025) between control and probiotic groups. However, it's essential to note the considerable heterogeneity among the studies, emphasising the need for a cautious interpretation of the results. Despite this variability, the study underscores the potential of probiotics to positively influence broiler meat quality, highlighting avenues for further research and standardisation in poultry production practices. These findings also contribute to a better understanding of probiotics' role in improving meat quality and meeting consumer preferences for nutritious and high-quality poultry products.

A survey into the utilization of probiotics and medicinal plants among individuals afflicted with gastrointestinal disorders in healthcare institutions in Saïda, Algeria

ABSTRACT Aim: Functional gastrointestinal (GI) disorders are recognized as a major public health concern worldwide. These disorders involve persistent digestive symptoms indicative of digestive tract dysfunction. Materials and Methods: A survey examining the utilisation of probiotics and medicinal plants as supplementary treatments was conducted on 160 patients with GI disorders at healthcare institutions in Saïda from March to April 2023 using questionnaires that had been previously adapted and tested for reliability with Cronbach’s alpha test. Raw data collected through the questionnaires were transferred to a database and analysed using SPSS software. Results: Overall, 49.38% of participants possessed knowledge of or actively utilised probiotics; such awareness was strongly associated with the participants’ educational attainment (p = 0.029). The noteworthy probiotic supplements were Biocharbon (36.09%), Lactocil (15.38%), Smebiocta (13.61%), Ultrabiotic Adult (12.43%), Effidigest (12.43%), and Ultralevure (7.69%). During crisis, individuals tended to consume natural goods rich in probiotics, including yoghurt (13.26%) and fermented milk (8.60%), as well as foods rich in prebiotic fibre, including vegetables (18.99%), fruits (13.26%), wheat (9.67%), bran (7.52%), rye (6.81%), and oat flakes (6.45%). Additionally, 77.56% of patients used medicinal plants during crises, with Mentha spicata (12.2%), Thymus vulgaris (11.3%), Pimpinella anisum (8.5%), Cuminum cyminum (8.0%), Punica granatum (7.8%), Trachyspermum ammi (7.5%), and Senna acutifolia (7.0%) being the more commonly favoured options in phytotherapy. The main focus of these herbs was to alleviate bloating (57%), constipation (30.12%), and diarrhoea (12.87%) (p < 0.001). The most frequently utilised plant parts were leaves (47.30%), seeds (25.21%), and bark (13.21%). Most patients (82.91%) favoured infusion as their preferred consumption method, and approximately 85.43% believed in phytotherapy’s ability to extend symptomatic relief. Conclusion: The understanding of probiotics is still in its infancy, whereas phytotherapy is more widely accepted by patients. Nonetheless, patients are open to the exploration of natural alternatives to conventional medicines.

Regulation of gut microbiota-bile acids axis by probiotics in inflammatory bowel disease.

Inflammatory bowel disease (IBD) is characterized by chronic and relapsing inflammation of gastrointestinal tract, with steadily increased incidence and prevalence worldwide. Although the precise pathogenesis remains unclear, gut microbiota, bile acids (BAs), and aberrant immune response play essential roles in the development of IBD. Lately, gut dysbiosis including certain decreased beneficial bacteria and increased pathogens and aberrant BAs metabolism have been reported in IBD. The bacteria inhabited in human gut have critical functions in BA biotransformation. Patients with active IBD have elevated primary and conjugated BAs and decreased secondary BAs, accompanied by the impaired transformation activities (mainly deconjugation and 7α-dehydroxylation) of gut microbiota. Probiotics have exhibited certain positive effects by different mechanisms in the therapy of IBD. This review discussed the effectiveness of probiotics in certain clinical and animal model studies that might involve in gut microbiota-BAs axis. More importantly, the possible mechanisms of probiotics on regulating gut microbiota-BAs axis in IBD were elucidated, which we focused on the elevated gut bacteria containing bile salt hydrolase or BA-inducible enzymes at genus/species level that might participate in the BA biotransformation. Furthermore, beneficial effects exerted by activation of BA-activated receptors on intestinal immunity were also summarized, which might partially explain the protect effects and mechanisms of probiotics on IBD. Therefore, this review will provide new insights into a better understanding of probiotics in the therapy targeting gut microbiota-BAs axis of IBD.

Correlation of Knowledge, Attitude, and Practice Toward Probiotics for the Digestive System Among Health Science Students.

BackgroundProbiotics have numerous health benefits to the digestive system, one of them being clinically able to prevent and treat diarrhea. The growing scientific evidence of probiotic benefits has led to increased production of probiotic products. Health science students, as future healthcare professionals (HCPs), should have more knowledge about probiotics to be able to give the right recommendation to their future patients and the larger community. This study aims to assess the knowledge, attitude, and practice towards probiotics of health science students in Universitas Padjadjaran, Indonesia.MethodsA cross-sectional study was conducted on 87 students from Medical Studies, Midwifery, Pharmacy, and Nursing majors in 2020. Proportional cluster random sampling was used to select the study subjects, and an online survey was used to collect the data. Final data were exported to statistics software for analysis. Scores of each variable were categorized. Kruskal–Wallis test was used to analyze the statistical differences among the four groups. Spearman’s rank correlation coefficient was used to analyze the relationship between knowledge, attitude, and practice variables.ResultsOf all respondents, 80% had adequate knowledge. More than half (52.9%) had a positive attitude, and most (62.1%) had a positive practice. There were significant correlations between knowledge-attitude and attitude-practice variables. Most respondents gained information on probiotics from the Internet (26%) and their lecturer (24%). P-value from Kruskal–Wallis test for knowledge, attitude, and practice are 0.466, 0.801, and 0.324, respectively.ConclusionMost respondents had an adequate level of knowledge, a positive attitude, and a positive practice towards probiotics. Incorporating scientific evidence regarding probiotics from various studies into all health science majors’ academic curricula and media may help equip the students with a better understanding of probiotics, therefore improving probiotics usage to prevent and treat digestive system diseases in the future.

Knowledge, attitudes, and understanding of probiotics among pediatricians in different regions of Saudi Arabia

BackgroundProbiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit upon the host. Knowledge and attitudes of health professionals have been reported to be at a medium level for probiotics. The objective was to evaluate the knowledge and practice styles about probiotics among pediatricians working in different regions of Saudi Arabia.MethodsThis cross-sectional study was conducted at pediatric hospitals in Saudi Arabia. A national survey of 550 pediatric providers (PPs) was conducted between January and March 2020 anonymously on their knowledge and practice styles regarding probiotics, and it was completed by pediatric residents (PRs), pediatric specialist (PSs), pediatric consultants (PCs), and pediatric gastroenterologists (PGs).ResultsThe survey had a response rate of 82%. Among the respondents, 57.7% were aware of the probiotic’s definition. There were significant differences in the percentage of participants who had little knowledge of probiotics (P < 0.05), with the highest being PRs and the lowest being PGs. The most common probiotic used by all participants was Lactobacillus acidophilus (63.3%), and Mycobacterium avium was prescribed the least often (8.6%). Most PRs and PSs correctly reported that probiotics reduce the risk of antibiotic-induced diarrhea (74.9 and 80.2%, respectively), but there were no significant differences among them.ConclusionsSignificant differences in knowledge and practice patterns exist for probiotics. Identification of knowledge gaps may be useful to develop educational materials to improve the proper definition, knowledge, and use of probiotics.

A cross sectional survey to assess healthcare professionals' attitudes to and understanding of probiotics

Consumers' belief in the benefits of probiotics is influenced by information they receive from healthcare professionals (HCPs). HCPs therefore need to be aware of the current evidence base in order to advise consumers appropriately. This survey aimed to establish HCP attitudes towards, and understanding of, the use of probiotics in healthcare. An online, cross-sectional survey was distributed to dietitians, paediatricians and General Practitioners (GPs) through three medical/health professional bodies: the British Dietetic Association (BDA), the European Society for Primary Care in Gastroenterology (ESPCG) and the European Paediatric Association (EPA). Paper copies of the survey were distributed at relevant medical congresses. There were 1360 respondents representing all three groups of HCPs. The majority of respondents (86.3%, n=1068) agreed that probiotics have a place in clinical medicine and were likely to recommend them (72.1%, n=882), yet only 55.7% (n=230) of dietitians were familiar with the World Health Organisation (WHO) definition of a probiotic. There was a positive, however, weak correlation between a high level of training and the likelihood of a respondent recommending a probiotic (r=0.24, p<0.005). Inadequate knowledge appeared to be a limiting factor in patients receiving evidence-based information and appropriate recommendations. The more concerns an HCP had, the less likely they were to recommend a probiotic regularly (p<0.005). The majority (91%, n=1099) of respondents cited a need for more education. HCPs recognise that probiotics have a place in clinical medicine and would recommend them if they had more information to support informed decision-making within patient care.

Effects of probiotic Enterococcus faecium NCIMB 11181 administration on swine fecal microbiota diversity and composition using barcoded pyrosequencing

Although our understanding of probiotics is increasing, basic information regarding their effect on the composition of the gut microbiome is scarce. The purpose of this study was to characterize the fecal microbiota of weaned piglets before and after probiotic intervention. The probiotic bacterium Enterococcus faecium NCIMB 11181 was administered to pigs for 2 weeks and fecal bacterial diversity using 16S rRNA gene pyrosequencing was analyzed. A more stable bacterial community, as indicated by increased bacterial diversity and richness, was observed after administration of the probiotic, compared with the control group. Regardless of the diet, Firmicutes and Bacteroidetes were found to be the dominant bacterial phyla in the pigs; however, inhibition of Proteobacteria was clearly evident in the probiotic group. In addition, the probiotic-fed group featured elevated levels of Lactobacillus, Enterococcus, Oscillibacter, Succinivibro, and Clostridium genera and decreased levels of Escherichia and Dialister genera, compared with the control group. This study demonstrated that the probiotic E. faecium NCIMB 11181 modulates the fecal microbiota of weaned piglets. This modulation is characterized by an increase in other bacterial species including L. johnsonii, L. fermentum, and L. kimchii and several Clostridium spp., which might be beneficial to the health of weaned piglets.

Maternal perspectives on the use of probiotics in infants: a cross-sectional survey.

BackgroundProbiotic products that may modify the intestinal microbiota are becoming increasingly available and known to consumers due to their potential to prevent or treat many pediatric health conditions. As scientific knowledge of the health benefits of probiotics increases, it is important to identify factors that may prevent their successful integration into patient care as well as to ensure effective translation of research findings. The aim of this study was to describe maternal perspectives on probiotics and their use in infants.MethodsMothers with a child aged two years or younger enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study were invited by email to complete a 29 item self-administered web-based questionnaire.ResultsA total of 413 mothers of the 1327 contacted completed the questionnaire. The majority (99.3%) of respondents had heard of probiotics and were aware that they contained live bacteria (87.0%); 89.3% had used a product containing probiotics themselves but only 50.8% had given one to their infant. Most mothers indicated they believed that probiotics were beneficial (73.1%) and none thought they were harmful. Over a third of mothers did not feel informed enough to make a decision on whether probiotics were safe to use in infants (36.6%).ConclusionsThe study demonstrates that awareness and understanding of probiotics is high among mothers in Alberta, Canada. However, there is still uncertainty regarding the benefit of probiotics as well as safety in infants which could be important factors determining therapeutic use in the future. Further studies that demonstrate beneficial effects and safety of probiotics in healthy infants as well as targeted knowledge translation should help to address these potential concerns.

Oral administration of Bacillus subtilis strain BSB3 can prevent heat stress-related adverse effects in rats.

To determine the efficacy of Bacillus subtilis strain in prevention of heat stress-related complications in rats. Male Sprague-Dawley rats weighing 250-300 g were treated by oral gavage with B. subtilis BSB3 strain or PBS twice a day for 2 days. Half of the rats of each group were exposed to heat stress (45°C, relative humidity 55% for 25 min), while the remaining rats were placed at identical conditions but at 25°C. Bacterial translocation, histological changes in the intestine, cytokines profile, serum lipopolysaccharide level (LPS), as well as vesiculation of erythrocytes were analysed and compared between groups. Adverse effects of heat stress (morphological changes in intestine, bacterial translocation, elevated levels of LPS and IL-10, increased vesiculation of erythrocytes) were observed only in rats not protected with B. subtilis strain and exposed to heat. All registered parameters in rats pretreated with bacilli and exposed to heat were similar to control groups. Bacillus subtilis BS3B strain was effective in the prevention of complications related to heat stress in rats. This work will contribute towards better understanding of probiotics' mechanisms of action and will bring new approaches to characterize and use of beneficial bacteria.

Is the role of probiotics friendly in the treatment of periodontal diseases !!

Probiotics utilize naturally occurring bacteria to confer a health benefit when administered in adequate amounts. A few conventional foods containing probiotics are yogurt, fermented and unfermented milk, soy beverages etc. Most often, they come from two groups of bacteria, Lactobacillus or Bifidobacterium. Probiotics have been extensively studied for their health promoting effects. Scientific understanding of probiotics and their potential for preventing and treating periodontal conditions is at its infancy, but moving ahead. Extensive research to create a probiotic product intended to maintain dental and periodontal health is needed.
