Filter by:The goal of this randomized clinical trial is to evaluate the effect on the microbiota and the reduction in the number and/or intensity of symptoms of gastrointestinal discomfort of consuming a probiotic or placebo for 6 weeks in adult women and men. The main questions to answer are: 1. To study changes in the alpha diversity of the microbiota. 2. To evaluate changes in the salivary cortisol. For this purpose, a randomized, double blind crossover study has been designed. Target sample size is 30 subjects. Participants will be allocated in two groups for 16 weeks (6 weeks consuming one of the products + 4 weeks wash-out period + 6 weeks consuming the other product). - Group 1 (n=15): 6 weeks daily consumption of one probiotic capsule + 4 weeks wash-out period+ 6 weeks daily consumption of one placebo capsule. - Group 2 (n=15): 6 weeks daily consumption of one placebo capsule + 4 weeks wash-out period+ 6 weeks daily consumption of one probiotic capsule.
Many veterans with Gulf War Illness developed chronic gastrointestinal symptoms during their deployment to the Persian Gulf. The pathophysiologic mechanisms of these chronic gastrointestinal symptoms are not well understood but cause significant morbidity in veterans. Our proposed studies will provide an innovative and novel treatment trial for chronic gastrointestinal symptoms in veterans with Gulf War Illness that were deployed into war zones. Given that there are currently no specific treatments for these disorders, and that current symptomatic approaches are far from ideal, proof of principle of our trial would be an extremely important advance as it would not only have a beneficial impact on the health of many thousands of our veterans, but also it would substantially reduce the many negative economic effects of this ailment on the VA Health Care System.
Bovine colostrum is a dairy food and the first milk produced by the mother cow. Abundant research exists revealing the valuable health benefits it confers due to its unique nutritional properties., including benefits to gastrointestinal health, fitness, and overall well-being.This study aims to test a specific food-grade supplement, ARMRA Colostrum Immune Revival, over a 12-week trial to better understand the well-being, fitness, and gut benefits. This trial will use two groups, one that suffers from gastrointestinal complaints frequently and another that exercises at least three days a week.
This mother-infant cohort study aims to determine the geographic differences in the microbial profiles in breast milk from mothers living in Malaysia and China that are potentially important determinants of infant development. It also aims to determine the impact of gut microbiome on infant health (temperament, gastrointestinal symptoms, eczema symptoms, and asthma symptoms).
The study is a single site, prospective, open label, observational, single arm trial in 30 patients with type 2 diabetes with GI complaints using 1 or more oral or injectable anti-hyperglycemic agents to investigate if altering the microbiome though Pendulum T2D dietary supplementation can further enhance the efficacy of the current treatment while reducing the GI associated symptoms in patients with Type 2 diabetes.
A double-blind randomized, placebo-controlled study will be performed with experienced endurance athletes to assess the effect of probiotics supplementation on the occurrence and intensity of the gastrointestinal symptoms, on performance and on the composition and function of the gut microbiota. The duration of the supplementation period, with Ecologic® PERFORMANCE supplements, is fourteen weeks. Standardized maximum exercise tests on a treadmill are performed before and after the supplementation period, as well as two performance tests (before) and one performance test (after). During the performance tests, the load is first submaximal for 1 hour, after which a time trial of 30 minutes will be performed. The measurements before and after the supplementation period are performed on individual days with at least 48 hours of relative rest in between. During the supplementation period, training diaries, a Profile of Mood States (POMS) questionnaire and a few questionnaires about dietary habits will be completed.
Different physical form of apples had a significant effect on satiety and blood sugar levels which was shown in a 1977 study by Haber and his team (Haber et al.1977).It was suggested that , this effect was due to processing of the apples which modified the bioavailability of carbohydrate and fiber content.However this was not enough to explain the mechanistic effect of the apples. Within the last decade, the role of magenetic resonance imaging has been very promising in understanding gastrointestinal function and physiology. Recent MRI studies have measured changes in gastrointestinal volumes due to the effect of fermentable carbohydrates. Apple contains fermentable carbohydrates or FODMAPs. They are known to be poorly absorbed in the small and exert an osmotic effect by increasing markedly small bowel water content in the intestinal lumen as demonstrated in imaging studies.(Murray et al 2014 and Placidi et al 2012). A reduction of FODMAPs in the diet of IBS sufferers has been found to alleviate functional gut symptoms demonstrated in several randomised controlled trials. In order to fully understand the 1977 Haber study, the investigators would like to repeat the study using modern MRI methods in healthy volunteers and measure the volume changes in the stomach, small bowel and colon. In addition appetite and symptoms would also be investigated after ingesting each test meal.
This study is a randomized double blind, placebo controlled trial to determine the efficacy of an oral probiotic in reducing antenatal Group B Streptococcus colonization. The goal of this study is to demonstrate that women in the probiotics group will experience; (1) reduced GBS prenatal colonization at 36± 2 weeks gestation and lower levels of GBS colonization, (2) less need for intrapartum antibiotic prophylaxis and (3) fewer prenatal gastrointestinal symptoms compared to women in the placebo group. Intrapartum measures were added and IRB approved in Feb 2020 as a pilot and feasibility substudy. The goals of this study are as follows: (1) Explore the effect of antepartum exposure to Florajen3 on maternal and neonatal residual GBS and the maternal microbiome. We anticipate that (1)At the time of labor, more women in the probiotics group will test negative for GBS on vaginal to rectal swabs compared to those in the placebo group and (2) Fewer neonates born to women in the probiotic group will have GBS on nasal-oral pharynx cultures within several hours of birth compared to those born to neonates in the control group.
The study evaluated the safety, tolerability and acceptability of a lifestyle modification program with nutritional supplementation designed to restore balance to healthy bowel function in generally healthy subjects
The main objective of the study is to investigate the effect of probiotic supplementation on lactose maldigestion.
