NCT ID: NCT04004273 Completed - Obesity Clinical Trials

Diabetes, Exercise and Liver Fat (DELIVER)

(DELIVER)
Start date: October 30, 2018
Phase: N/A
Study type: Interventional

This randomised controlled trial will determine if exercise (150 - 200 min per week, 6 weeks) can beneficially modify liver fat quality in non alcohol fatty liver disease patients with type 2 diabetes mellitus (n = 26, 13 per group). Liver fat quality will be assessed via magnetic resonance (3T) spectroscopy (1H-MRS) using validated methods.

NCT ID: NCT03989882 Completed - Inflammation Clinical Trials

Wheat Germ Supplementation Will Improve Markers of Gut Health, Inflammation, and Insulin Resistance in Overweight Adults

Start date: May 28, 2019
Phase: N/A
Study type: Interventional

The objective of this pilot study is to determine the effects of wheat germ (WG) supplementation on gut health and subsequent effects on markers of inflammation and insulin resistance in overweight individuals. WG is a by-product of wheat processing and an excellent source of omega-3 fatty acids, vitamin E, and fiber. A few studies have shown the health benefits of WG including gut modulatory potential, but the prebiotic functions of WG in humans remain in question and warrant further investigation.

NCT ID: NCT03966846 Completed - Obesity Clinical Trials

Kefir and Metabolic Syndrome

Start date: March 2015
Phase: N/A
Study type: Interventional

Metabolic syndrome is a cluster of metabolic disorders which increases the risk for diabetes and cardiovascular disease. In recent years, research has shown that probiotics may have positive effects on metabolic syndrome components. Although several health-promoting effects of kefir, have been suggested, there is limited evidence for its potential effect on metabolic syndrome. Therefore, it is necessary to clarify the effects of kefir on metabolic disorders including obesity, dyslipidemia, diabetes, and hypertension. To address the research gap, this study aimed to investigate the effects of daily kefir consumption on metabolic syndrome components, inflammatory response and gut microbiota composition in adults with MetS. The study was planned as a randomized, controlled, parallel design and completed with a total of 62 individuals who were diagnosed with metabolic syndrome according to the International Diabetes Federation (IDF) criteria. Participants were randomized into two groups and received daily 180 ml of kefir (n=31) or milk (as control) (n=31) for 12 weeks. Participants were assessed at baseline, week 4, week 8, and week 12 and at all controls dietary records, anthropometric measurements, and blood samples were collected. At baseline and 12th-week fecal samples were also collected in order to analyze gut microbiota composition.

NCT ID: NCT03952000 Completed - Clinical trials for Diabetes Mellitus, Type 2

Influence of Prior Walking on Postprandial Metabolism in Centrally Obese Men

Start date: January 3, 2019
Phase: N/A
Study type: Interventional

The present study will investigate the effect of prior walking on postprandial metabolism and endothelial function in centrally obese South Asian and White European men. Participants will complete two, 2-day trials in a random, crossover design separated by at least a week. On day 1, participants will either rest or complete a 60 minute walk at 60% maximal oxygen uptake. On day 2, participants will arrive at 08:00 having fasted overnight and a baseline venous blood sample and endothelial function measurement will be taken. Participants will consume a high-fat breakfast and lunch and 12 subsequent venous blood samples will be taken throughout the day at standardised intervals to measure a variety of coronary heart disease risk markers. A second endothelial function measurement will be completed 2 hours after the breakfast. Blood pressure will be measured every hour. It is expected that the South Asian participants will have impaired metabolism and endothelial function compared to their European counterparts but the bout of exercise performed on day 1 will mitigate these responses.

NCT ID: NCT03941704 Completed - Insulin Sensitivity Clinical Trials

Pulse-based Foods for Alleviation of Negative Consequences of Sedentary Behaviour

Start date: May 15, 2019
Phase: N/A
Study type: Interventional

The hypothesis is that consumption of pulse-based foods (i.e. containing chickpeas, lentils, and split peas) during the workday will improve insulin sensitivity, glucose tolerance, blood lipids, body composition, and blood pressure in sedentary office workers.One-hundred office workers from a university campus will participate in a cross-over study where they will be randomized (i.e. assigned by chance) to receive pre-packaged pulse-based lunches and snacks to replace their usual lunches/snacks during the work day OR to continue consuming their usual diets for two months. After the first dietary intervention, they will undergo a 1-month "wash-out" and then participate in two months of the opposite dietary intervention. The main outcome to be assessed is change in glucose and insulin (i.e. blood sugar control) determined during an oral glucose tolerance test. Secondary outcomes include changes in body composition, lipids, and blood pressure. During the pulse-based diet phases, participants will be supplied with a ready-to-eat lunch and two snacks to eat during each workday. These will contain a total of 150g/d dry weight (250g/d wet weight) pulses

NCT ID: NCT03929419 Completed - Insulin Sensitivity Clinical Trials

"Effect of Central Insulin Administration on Whole-body Insulin Sensitivity in Women"

Start date: April 21, 2019
Phase: N/A
Study type: Interventional

The human brain is an insulin sensitive organ. Brain insulin action modulates peripheral insulin sensitivity in young lean men. As a underlying mechanism, the investigators previously detected suppression of endogenous glucose production and stimulation of glucose disappearance to peripheral tissue in response to brain insulin delivery by nasal spray. Whether this holds true in young woman is unknown, since differences in brain insulin response between sexes have been reported. The investigators will address this question by combining the delivery of insulin to the brain as nasal spray with hyperinsulinemic euglycemic clamp experiments in natural cycling women. In the planned randomized, placebo controlled cross-over study, female participants will undergo four hyperinsulinemic euglycemic experiments with tracer dilution, two in the first phase and two in the second phase of their menstrual cycle. On one of the study days per menstrual phase, subjects will receive intranasal insulin administration, on the other placebo spray. The protocol has been successfully applied previously in men. Based on the results of this trial, the investigators calculated a required sample size of N=10 for the planned study in women. These experiments will help to better understand the role of brain insulin action in a broader sense. The results can be the basis for larger clinical trials that address the sex-specific impact of brain insulin resistance for glucose metabolism and diabetes risk.

NCT ID: NCT03898518 Completed - Blood Pressure Clinical Trials

The Effects of a Jump Rope Exercise Program on Body Composition and Self-efficacy in Obese Adolescent Girls

Start date: October 3, 2010
Phase: N/A
Study type: Interventional

The purpose of this study was to examine the impact of a 12-week jump rope exercise program on body composition, blood pressure, insulin resistance, and academic self-efficacy in prehypertensive adolescent obese girls. Forty-eight prehypertensive adolescent obese girls participated in this study. The girls were randomly divided into the jump rope exercise intervention group (EX, n=24) and control group (CON, n=24). The EX group performed a jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 50 minutes in duration). The CON group did not participate in any structure or unstructured exercise protocol. Blood pressure, body fat percentage, waist circumference, blood glucose and insulin, homeostatic model assessment - insulin resistance, and Academic Self-Efficacy were measured before and after the 12-weeks study.

NCT ID: NCT03898037 Completed - Obesity Clinical Trials

Effect of Lifestyle and/or Metformin Intervention on Pregnancy Outcome, A Pilot Randomized Controlled Trial

Start date: June 13, 2019
Phase: N/A
Study type: Interventional

The purpose of pilot trial is to compare the efficacy of lifestyle intervention, metformin intervention, lifestyle combined with metformin intervention in improving assisted reproductive technology in non-polycystic ovary syndrome(pcos) patients with overweight/obesity and insulin resistance compared with conventional clinical education. Subjects who meet the inclusion criteria will be randomized to four groups: lifestyle intervention group, metformin intervention group, lifestyle combined with metformin intervention group, and routine clinical education group. Subjects of above three intervention group will start ovulation stimulation treatment after reach the aim or duration of intervention and routine clinical education group has no intervention. All subjects are treated with the same procedures, including a long ovarian stimulation regimen, oocyte retrieval, and fertilization, followed by a planned transfer of two day-3 embryos. The primary outcome is ongoing pregnancy rate.
