Active clinical trials for "Metabolic Diseases"

Diet and nutrition are key to maintain human health. Westlake N-of-1 Trials for Macronutrient Intake (WE-MACNUTR) trial investigates individualized postprandial glycemic responses to different proportions of dietary fat and carbohydrates intake using an n-of-1 experimental study design. The experimental diets are isocaloric high fat, low carbohydrate (HF-LC) or low fat, high carbohydrate (LF-HC). With standardized intervention and strictly controlled eating behaviors, the WE-MACNUTR study identifies specific HC-responders and HF-responders in terms of postprandial glucose response. This is a follow-up study offered to participants who have completed the WE-MACNUTR study in 2019. Volunteers will be asked to participate in four 5-d periods while wearing glucose monitors (Abbott Freestyle Libre) with the following experimental sequence: 1) a washout diet, 2) HF-LC or LC-HF diet, 3) a washout diet, 4) HF-LC or LC-HF diet. The experimental diet will be randomly assigned. Participants will be asked to provide a fasted blood sample and to collect fecal, urine and saliva samples at each visits.

Dairy products represent an important food group in human nutrition as a source of calcium, protein, functional fats and low-glycaemic sugar lactose. While traditionally consumed natural milk and yogurt have low sugar content, many flavoured liquid dairy products such as chocolate milk, or fermented products such as yogurt have added sugar. Our recent studies have shown that the partial reduction of added sugar in chocolate milk and yogurt is not associated with any inferior sensory characteristics such as taste and pleasantness compared to their full-sugar counterparts. The current project will investigate whether the liquid dairy products with reduced sugar content (value-added products) have any benefits on blood glucose control in humans.

Aim: The aim of the clinical trial is to study the accuracy of the TensorTip device compared with registered (FDA-approved) invasive and non-invasive devices. Hypothesis: Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip finger-mounted device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration.

Despite exercise training decrease blood pressure in 'average' terms, there is a wide interindividual variability after exercise training, being yet unknown what mode of exercise (e.g. endurance, strength, concurrent, or high intensity interval training) produce more/less non-responder (NR) prevalence (i.e., percentage of subjects who experienced a non-change/worsened response after training in some outcome).

TAPESTRY-CM pilot study is a 12-week pilot test of the TAPESTRY-CM using a web application (APP) to help patient manage their diabetes and hypertension and other chronic conditions by assisting them in setting goals and connecting them to their healthcare team.

The investigators will compare 16sRDNA profile in cases and controls in order to identify bacteria associated with metabolic diseases that reside both in intestinal crypts and in blood.

Adipose tissue (AT) has specific alterations in obesity in particular increased fibrosis amount compared to lean subjects. Fibrosis amount measured by immunohistochemistry on adipose biopsies appears to to predict weight loss response after a bariatric surgery. Non invasive tools to measure fibrosis needs to be validated. The investigators primary aim is to validate a new device able to measure adipose tissue stiffness. Thus the investigators plan to compare the stiffness results obtained with the device to the quantification of fibrosis using immuno-chemistry in massively obese patient's candidates to a bariatric surgery.

The purpose of this study is to test how soluble epoxide hydrolase (sEH) inhibition with GSK2256294 affects tissue sEH activity and insulin sensitivity.

The HEPAFIT Study aims to examine whether a 6-months physical education program has benefits on hepatic metabolism and cardiovascular health as well as on selected physical fitness and mental health outcomes among adolescent overweight/obese from Bogota, Colombia.

All participants underwent three experimental trials, namely downhill running (DR), level running (LR), and the control (CON) in a cross-over design. Each trial lasted for 2 days. The participants were fed the same breakfast and lunch on day 1 in each trial. The participants arrived at the laboratory at 18:00 on day 1 and ran on the treadmill at 60% VO2max (downhill and level surface trials) or rested (CON trial) for 30 min. Subsequently, they were fed a standardized dinner (A meal box containing chicken, vegetables, and rice, 692 kcal, with 50% energy from carbohydrate, 32% from fat, and 18% from protein) within 20 min. The participants returned to the laboratory at 07:30 on day 2 after an overnight fast. After baseline blood and gas samples were collected, the participants were fed a high-fat meal that included cereal, white bread, whipping cream, cheese, and butter. The high-fat meal provided fat 1.2 g/kg (65% energy), carbohydrate 1.1 g/kg (27% energy), protein 0.33 g/kg (8% energy), and 16.5 kcal/kg. A 10-mL blood sample was collected from a forearm vein into nonheparinized tubes before and immediately after exercise or rest on day 1. On day 2, postprandial blood samples were collected from forearm veins into nonheparinized tubes by using an indwelling venous needle and a three-way stopcock. A 10-mL blood sample was collected before (0 h) and 0.5, 1, 2, 3, 4, 5, and 6 h after the high-fat meal.
