6 Clinical Trials for Various Conditions
The purpose of this research is to determine the effect of fermented vegetable consumption on LAB abundance and tolerability of the intervention in young healthy people before conducting a full RCT with older participants.
The purpose of this research is to assess mucosal immune function responses in the gastrointestinal (GI) tract to twice-daily yogurt consumption. Previous research has shown that dairy yogurt intake can benefit gastrointestinal health. The current study will determine whether a dietary intervention with dairy yogurt will improve mucosal immunity and the gut microbiome.
This study will be conducted to determine the effect of daily Tetrasol consumption in supporting gut health using assessments of gastrointestinal symptoms (GSRS) and bowel habits (BSS) as primary outcome measures. The investigators also intend to explore fecal and blood biomarkers of intestinal permeability/function, determination of anxiety and stress levels through both validated assessments and saliva and blood biomarkers, establishment of intervention safety and tolerability through comprehensive metabolic panels and overall compliance, explore the effects of the intervention on inflammation and acute stress (Cold Presser Test), blood lipid profiles, and gut microbiota composition as secondary outcomes.
The objective of the current study is to evaluate the effect of whole cell fermentate on gut health, including GI system function, such as supporting consistency and regularity of bowel habits, as well as changes in microbiota. The role of the GI system can also be extended to immune regulation because approximately 70% of the entire immune system in the body is located around the gut. Thus, the health and wellbeing of the gut can have a great impact on whole-body health. Therefore, this study will assess the effect on overall immune function.
Background: - Gastrointestinal cancers can occur in the throat, stomach, gallbladder, liver, pancreas, and colon. Researchers are interested in evaluating how active the immune system is in trying to fight the cancer by studying blood and tumor tissue donated from individuals who have been diagnosed with gastrointestinal cancers. Objectives: - To collect blood and tumor samples from individuals who have been diagnosed with gastrointestinal cancers in order to study the immune system s response to the cancer. Eligibility: - Individuals at least 18 years of age who have been diagnosed with throat, stomach, gallbladder, liver, pancreatic, or colon cancer, and are scheduled to be treated at the National Institutes of Health. Design: * The study will require at least one but no more than four visits to the National Institutes of Health Clinical Center. * Participants will be screened with a physical examination and medical history, and will provide a baseline blood sample for study. * Participants will provide additional blood samples 2 and 4 months after the baseline sample, as well as a final sample at the completion of the treatment protocol. * Participants will provide tumor tissue samples only if they undergo a surgical procedure related to the treatment for their gastrointestinal cancer. * No treatment will be provided as part of this protocol.
The purpose of this study is to evaluate the effect of daily intake of orange pomace on gastrointestinal function as measured by stool frequency. Additional outcomes will include aspects of digestive health, diet quality, and fasting blood glucose and lipid concentrations. Possible explanations for the mechanism of the pomace will be explored in microbial ecology analyses.
