Filter by:This single site study is a randomized, controlled, partially-blinded design enrolling a minimum of 516 healthy volunteers, where each subject will receive two of the planned study products on the product application sites of the abdomen and/or groin.
A total of 50 patients with metastatic colorectal cancer will be enrolled in the study. The patients were randomly divided into the WLS-intervention group and the control group. The two groups of patients were given the most appropriate medication according to the specific conditions of the disease. Patients in the intervention group received additional oral administration of Weileshu, a probiotics product (Tongchuang Biotechnology).
Foods in the human diet can affect the development of diseases over time, such as diabetes or heart disease. This is because the amount and types of foods in the diet eat can affect a person's weight, and because different foods are metabolised (processed) by the body in different ways. Scientists have also found that the bacteria in the human gut (the gut microbiome) affect their metabolism, weight and health and that, together with a person's diet and metabolism, could be used to predict appetite and how meals affect the levels of sugar (glucose) and fats (lipids) found in blood after eating. If blood sugar and fat are too high too often for too long, there is a greater chance of developing diseases such as diabetes and cardiovascular disease. The gut microbiome is different in different people. Only 10-20% of the types of bacteria found in the human gut are found in everyone. This might mean that the best diet to prevent disease needs matching to a person's gut microbiome and it might be possible to find personalised foods or diets that will help reduce the chance of developing chronic disease as well as metabolic syndrome. The study investigators are recruiting volunteers aged 18-70 years to take part in a study that aims to answer the questions above. Participants will be asked to consume standardised meals on up to 8 days while wearing glucose monitors (Abbott Freestyle Libre) to measure their blood sugar levels. Participants will also be required to prick their fingers at regular intervals to collect small amounts of blood, and to record their appetite, food, physical activity and sleep using apps and wearable devices. They will be asked to collect a fecal and saliva sample before consuming the standardised meals, and to provide a fasted blood sample at the end of the study period.
This study evaluates the presence and quantity of non-caloric sweeteners in newborns umbilical cord blood, and in their mother's breast milk at delivery, at 2 months, 4 months and 6 months of age. Microbiota composition will be evaluated in milk and in feces of both mother and child.
The purpose of the project is to investigate if consumption of the fermented tea beverage kombucha has an effect on the gut and/or oral microbiota, and further if it depends on the content of living bacteria or is inherent even to sterilized kombucha. This will be studied by a clinical trial in which healthy individuals will be given living kombucha, sterilized kombucha or water. The participants will consume one bottle (33 cl) of their designated drink per day for 21 days. Fecal and saliva samples will be collected before, directly and ten days after the intervention. These will then be examined to see if there is a change in the micro flora due to the kombucha.
Childhood gastroenteritis establishes gastrointestinal disease and increase the economic burden, and the pediatric population is especially vulnerable to these gastrointestinal infections. The aim of this study is to evaluate the role of intestinal microbiota and their relationship with childhood gastroenteritis.
Zeolite clinoptilolite is a volcanic mineral from the group of zeolites. The porous structure is associated with a large inner surface. Due to the anionic framework charge, ions (e.g., Pb^2+) can be absorbed or exchanged. The specific Panaceo PMA zeolite is approved as a class IIa medical device for the repair of the intestine inner lining. It is CE certified and complies with the relevant European Union regulations in terms of safety and effectiveness. Zeolite is known for its absorbing properties. Because of these properties and the results of several human studies, it warrants the investigation of possible effects on specific indications in human medicine, e.g. irritable bowel syndrome. The diagnosis "irritable bowel syndrome (IBS)" is according to the ROME Foundation, an US medical society. IBS is a disorder with dysfunction of the bowels, a latent inflammation is discussed. The present study aims to evaluate the following effects in patients with IBS: - Primary endpoint: effect on the symptoms of IBS. - Secondary endpoint: intestinal wall permeability, integrity of the tight junctions as measured by the change in zonulin concentration in the stool. - Further endpoints: - Inflammation parameters and anti-inflammatory laboratory parameters. - Biodiversity of the gastrointestinal microbiome. - histamine-associated parameters. - Constipation as a possible side effect. For this purpose, a double-blind randomized controlled trial (RCT) is realized prospectively in a monocentric outpatient-controlled study. The subjects take the test compound daily (verum, reference substance) for 12 weeks and document the intake of the study-substance, intake of medications, stool-frequency and consistency. They receive "before" and "after" the intervention phase a blood and stool analysis for the determination of parameters for intestinal wall integrity (zonulin) inflammation (hsCRP, interleukin-10, calprotectin), histamine metabolism, microbiome diversity. The pilot study is realized ahead of the detailed planning of a later main study.
A sterile swap specimen taken from the scalp of the patients with psoriasis vulgaris or seborrheic dermatitis and the volunteer control group will be examined in our study. The examples of the microbiota of the patients will be taken both the lesional scalp and the lesion-free part of the scalp. Then, the microbiota differences between the lesioned scalp and the lesion-free scalp of both groups, and the microbiome differences between the two groups and the control group will be evaluated.
Animal models and studies on small samples of obese adults have shown that gut microbial diversity and certain types of bacteria could predict the efficacy of the dietetic treatment to improve body mass index (BMI) and the components of metabolic syndrome (MetS). Gut microbiota could distinguish the obese with metabolic syndrome patient than that metabolically healthy. Dietetic therapy could induce changes in the microbiota that could lead to improvement of BMI and the components of the MetS. The aim of MICROBEkids is to test whether the motivational intervention a motivational intervention (OBEMAT2.0) (PI15/00970) is more effective than the conventional intervention to increase the gut microbial diversity and, as a consequence, to improve BMI and MetS components. The role of gut microbiota (through modulation of the short chain fatty acids) will be analyzed as cardiovascular risk factor and as predictor of treatment success. These objectives will be achieved through a clustered clinical trial design with an intervention group that will receive a motivational therapy compared to a control group that will receive a conventional intervention, both during 12 months. The study sample are 319 children (n= 167 in the intervention group) that were enrolled in the clinical trial OBEMAT2.0 (PI15/00970), have had a comprehensive clinical assessment before the intervention (ages 8 to 14) and after 12 months (+3) of therapy (ages 9 to 15) and furthermore have participated in a biological samples collection for the investigation on childhood obesity (COLOBEPED, reference C.0004585).
This study investigates differences in microbiota profiles and metabolite levels between mild and severe IBS patients, compared to matched healthy controls. Two fecal samples, with one month in between, will be analyzed. Secondary parameters such as dietary intake, quality of life and stool pattern will be assessed.
