Filter by:Objective of Clinical Trial: To test, in a blinded study the bioavailability of Genepro Generation 3 (GEN3) Protein as compared to whey protein. This study is intended to show the equivalent value of Genepro Gen3 as compared to whey protein (1scoop (12g) Genepro Generation 3 (GEN3) compared to 30g serving of whey protein). Total Serum Protein levels will be tested every other week to evaluate blood protein levels in each participant
This is a market research, observational study to evaluate the tolerability and acceptability of MCT supplements for young children, young people and adults with intractable epilepsy, GLUT-1 or PDHD from 3 years to adulthood.
This is a market research, observational study to evaluate the tolerability and acceptability of MCT supplements for young children and young people with intractable epilepsy, GLUT-1 or PDHD from 3 years to adulthood. Patients with a confirmed diagnosis of a fatty acid oxidation disorder, which requires a specialist diet including MCT will be included in this study
Linear growth failure, a manifestation of chronic undernutrition in early childhood, is a recalcitrant problem in resource constrained settings. The underlying causes of growth failure are multifactorial, but persistent and recurrent infection and inflammation of the gastrointestinal tract and immune activation, a condition commonly referred to as environmental enteropathy, is an important contributor. A highly enriched 13C-Sucrose Breath Test, a measure of sucrase-isomaltase activity, will be evaluated as a non-invasive biomarker of environmental enteropathy, and more specifically of intestinal brush border enzyme activity in 6 resource poor countries (Bangladesh, India, Jamaica, Kenya, Peru and Zambia) in 100 volunteers aged 12-15 months (total n=600) and evaluated relative to the lactose rhamnose test and linear and ponderal growth over a 3-6 month period following biomarker assessment. Field usability will also be assessed.
Comparing the effect of Liraglutide on bile acid malabsorption, with colesevelam
This project will test a unique botanical formula designed to inhibit alpha amylase (the primary starch degrading digestive enzyme) and inhibit sucrase (the primary sucrose degrading digestive enzyme) in order to reduce acute post prandial glycemia regardless of nutritive carbohydrate source.
Bile acid diarrhoea is a chronic disease that impairs quality of life. One in 100 has the condition and many suffer from the disease without knowing. The current test is called SeHCAT and is expensive and time-consuming and is unavailable in many places, including the US. The disease is often misdiagnosed as irritable bowel syndrome and estimated one third of patients with irritable bowel syndrome of the mixed type and the diarrhoea predominant type suffer from bile acid diarrhoea without knowing. A blood test called 7α-hydroxy-4-cholestene-3-one (C4) could make it much easier to diagnose bile acid diarrhoea. To establish the new test, the results of both C4 and SeHCAT are compared with the treatment effect of the drug called colesevelam. We invite patients who are referred for the SeHCAT test to participate in the trial. The SeHCAT test takes two days that are one week apart. The study patients register stool habits with a diary in the week between the SeHCAT visits. Based on the diary results, we screen for eligibility; e.g. a certain degree/severity of diarrhoea is required for participation. We treat eligible study patients (i.e those with diarrhoea) with either colesevelam or placebo (medicine without effect) that is randomly assigned. 170 study patients need to complete the treatment. We aim to validate (ie. compare) both the C4-test and the SeHCAT test with the colesevelam treatment response as the reference.
This study evaluates the effect of different methods of preparation (cooked and consumed hot vs cooked, cooled overnight and consumed cold) and variation in the activity of salivary amylase on the glycemic index and carbohydrate digestibility in healthy human subjects. The effect of genetic variation in small intestinal starch digesting enzymes on glycemic index and starch digestibility will also be assessed.
A randomized, double-blind, placebo-controlled clinical study in human leukocyte antigen (HLA)-DQ 2.5+ adults with celiac disease (CeD).
Obesity is an independent risk factor for colorectal cancer (CRC) although the underlying mechanisms have not been elucidated. Dietary nutrients play a key role in both the prevention and promotion of CRC. While iron is an essential nutrient, excess iron is associated with carcinogenesis. Unlike the systemic compartment, the intestinal lumen lacks an efficient system to regulate iron. In conditions when dietary iron malabsorption and intestinal inflammation co-exist, greater luminal iron is associated with increased intestinal inflammation and a shift in the gut microbiota to more pro-inflammatory strains. However, treatments designed to reduce luminal, including diet restriction and chelation, are associated with lower intestinal inflammation and the colonization of protective gut microbes. Obesity is associated with inflammation-induced, hepcidin-mediated, iron metabolism dysfunction characterized by iron deficiency and dietary iron malabsorption. Obesity is also linked to intestinal inflammation. Currently, there is a fundamental gap in understanding how altered iron metabolism impacts CRC risk in obesity. The investigator's objective is to conduct a crossover controlled feeding trial of: 1) a "Typical American" diet with "high" heme/non-heme iron", 2) a "Typical American" diet with "low" iron, and 3) a Mediterranean diet with "high" non heme iron and examine effects on colonic and systemic inflammation and the gut microbiome.
