Filter by:This randomized, placebo-controlled, double-blind clinical trial aims to evaluate the efficacy and safety of probiotics as food supplements in preventing antibiotic-associated diarrhea. The study will involve 82 patients who will be randomly assigned to one of two groups: an experimental group receiving a probiotic containing Lactobacillus acidophilus LA85, and a placebo group. The primary outcomes measured include the number of days until the onset of diarrhea, the duration of diarrhea (if it occurs), gastrointestinal quality of life evaluation using the GIQLI questionnaire, and overall patient satisfaction.
To evaluate the change of S. mutans and Lactobacillus spp. counts after all dental treatments were completed under general anesthesia and compare the groups in case of using probiotics and not using probiotics with the time for 6-months follow-up period.
Gluten intake spreads worldwide, being the major food protein consumed in the Western diets (up to 20 g gluten/d). But gluten has unique and unusual features. It resists the complete luminal digestion by gastric, pancreatic and intestinal brush border enzymes, and is susceptible to post-translational modification (deamidation) by mucosal transglutaminases. Apart from partial digestion, gluten per se has a negative impact on a consistent part of the worldwide population, which mainly results in the manifestations of celiac disease (CD) or other gluten-related disorders. This study will enable to test in vivo a novel multi-species probiotic that in vitro has proven to degrade gluten to non-immunotoxic peptides.
This study is intended to investigate the use of probiotics (LAB4 probiotics, Cultech, Port Talbot, Wales, UK) and the effect this has on gastrointestinal symptoms experienced during elite long-distance triathlon (ironman) competition, as well as the composition of the gut bacteria in the athlete. Long-distance triathlon events frequently induce gastrointestinal discomfort due to the duration of the event (8-17 hours), the intensity of the exercise and the ingestion of large amounts of sugars throughout the event. Data will be collected from athletes participating at the Kona ironman World-championships. Participants will supplement with either probiotic tablet, or placebo (sugar-pill) for 4-weeks prior to competition. Athletes will be both male and female age-group athletes from any qualifying age category (age categories are as follows: 18-24; 25-29; 30-34; 35-39; 40-44; 45-49; 50-54; 55-59; 60-64; 65-69; 70-74; 75-79; 80-84). The main investigation of the study will be the occurence/frequency/severity of gastrointestinal symptoms during training and competition between groups.
Based on alterations in the intestinal microbiota in children with ASD and the high comorbidity between ASD and ADHD, the aim of this project was to assess whether the administration of probiotics with strains related to the production of the neurotransmitters dopamine and GABA had a positive effect on social behavior, attention, and behavior.
The present study is a double-blinded randomized clinical trial with a duration of 28 days.
Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder. Gut microbiome dysbiosis may be associated with the pathophysiology of ADHD. Investigators previously found the relative abundance of Sutterella stercoricanis were increased and Bifidobacterium bifidum were decreased in the ADHD group. Investigators hypothesize that ADHD patients receiving supplementary Bifidobacterium bifidum (Bf-688) is able to increase the proportion of Bf-688; inhibit the proportion of Sutterella; and improve ADHD symptoms.
Sub-project 1 Background:With the increasing number of shift workers required for social and economic activities, increasing prevalence of metabolic diseases has been found in this group of people. Although reasons for this include reduced physical activity owing to unfixed working hours, lack of sleep or disturbances in the circadian rhythm may also be related to the occurrences of type 2 diabetes or metabolic syndrome. The mechanism may be due to sleep deprivation induced activation of the hypothalamic- pituitary- adrenal axis (HPA axis) that affects blood glucose metabolism. The gut brain axis might adjust the HPA axis via the bottom-up pathway through vagus nerve, the neuroendocrine system, or the immune system. It is also possible that physiological or psychological stressors might influence intestinal function through the top-down pathways. Associations between microbiota and many chronic diseases, including metabolic syndrome, diabetes, obesity, neurodegenerative diseases, or mental diseases have been investigated in recent years. However, the application of using probiotics in treating sleep disorders is still lacking. The probiotics used in this proposal are selected to be more related to mental conditions. The PS128, which belongs to Lactobacillus plantarum subsp. plantarum and PS23 belongs to Lactobacillus paracasei group. Both PS128 and PS23 probiotic capsules contain 10 billion CFU (colony forming units) of PS128 or PS23. The PS23 heat-treated probiotic capsule contain 10 billion PS23 cells. The main research hypothesis: Is it possible to develop the relevant probiotic treatment model?Our intended analysis was set a priori to analyze each probiotic vs. the placebo. Sub-project 2 Information technology (IT) is an industry related to productions of computers, information processing, or telecommunications. Such industry highly relies on the knowledge and solutions provided by professional IT specialists. Literature has described that the subjective stress scores were higher in IT specialists that developed diabetes, hypertension, and depression. Specific probiotics, also known as psychobiotics, may have the effects of alleviating levels of stress and mood symptoms. Therefore this open-label designed, single arm, baseline-controlled trial aiming to examine whether an 8-week intervention of a novel psychobiotic Lactobacillus plantarum PS128TM (PS128TM), may improve self-perceived stress and mood symptoms among high-stress IT specialists.
In order to evaluate the effects of supplementary probiotics and their metabolites on oral environment and oral microbiota, Taiwan FDA No. 88037803 will be used to evaluate the effects of oral probiotic candidate strains from previous research results and develop oral probiotic products.
This study aim to investigate the roles of the test article in improving gastrointestinal functions and gut microbiota of humans. A total 40 healthy adults were recruited and randomly divided into experimental and control groups, with 20 subjects each, for a 4-week trial. The subjects took the test article, "Super 13 Pro & Prebiotics" or the control article, "The placebo without Super 13 Pro & Prebiotics" during the 4-week drug-intake period. Fecal specimens were collected at the 0th, 2nd, and 4th weeks of the trial for analyzing the bacterial counts of Bifidobacterium spp., Clostridium perfringens, Lactobacillus spp., and Coliform.
