Filter by:This study is a prospective cohort study, following 80 morbidly obese patients undergoing bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB). The investigators are measuring intestinal microbiota (IM) and oral microbiota (OM) at the beginning before any treatment, at the time of surgery, which is after a very low calorie standard diet, and 1 and 6 months after surgery. The investigators assess whether changes in IM are related to changes in insulin resistance (IR), other features of the metabolic syndrome (MetS) and OM.
A total of 42 premenopausal women diagnosed clinically as having insulin resistance. Their ages ranged from 35 to 45 years old; their body mass index was >30 kg/m2 and They were obese women complained of insulin resistance and non diabetic or cardiovascular disease, were randomly assigned to group A participated in aerobic & resistive exercise program, and group B participated in aerobic exercise and followed prescribed diet restriction program. Both of the groups (A&B) followed the treatment program 3 times per weeks for 8 weeks. Assessment of the fasting glucose, fasting insulin, and HOMA test of insulin resistance were measured for all subjects in both groups (A and B) was carried out before and after the end of the treatment program
Previous preclinical investigations have found that Medicago sativa promotes the decrease of glucose concentrations. To evaluate the acute effect of Medicago sativa administration on glucose tolerance, insulin secretion, and insulin sensitivity in healthy individuals.
The present study will investigate the effect of prior walking on postprandial metabolism and endothelial function in healthy South Asian and White European women. Participants will complete two, 2-day trials in a random, crossover design separated by at least 3 weeks to control for the menstrual cycle phase. 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.
Gut microbiota may play a key role in many metabolic diseases, including type 2 diabetes (T2D). Consumption of high-fat/high-sugar western diet seem to alter human resident microbiota towards reduced genetic diversity and to influence its metabolic activity towards enhanced energy extraction. Plant-based diets are effective in the treatment of T2D but it is not clear whether their effect results solely from diet composition or whether it is mediated, at least partly, by different microbiota and its metabolic activity. One possible therapeutic approach is replacement of "pro-diabetic" microbiota with its "healthy" variant but what the "healthy" microbiota is and under which conditions this microbiota could stay stable and functional is not known. The aim of the proposed study is to identify possible metagenome/metabolome characteristics in different human cohorts (T2D vs vegans), to assess the stability of vegan microbiota in T2D-like environment and to evaluate the possibility to influence human T2D microbiota/metabolome towards more protective composition by dietary intervention.
This is a single-center randomized crossover trial. The investigators will target completion of 15 adults (age 18-65 years) with Type 1 Diabetes who use an insulin pump. After completion of the Screening Visit, each subject will participate in a 28-day at home Data Collection Period while using their personal insulin pump, a personal glucometer, a study CGM, and a study activity tracker (i.e., Fitbit). This data collection period may be extended to obtain to gather more days of quality data, if needed per principal investigator judgement. Once the data has been collected and processed, subjects will participate in two 24-hour admissions (Experimental and Control Admission) in a semi-controlled environment (i.e., hotel), performed in the assigned random order. During both admissions, subjects will use the personal insulin pump and glucometer, and a study CGM. The exercise session will consist of three 15-minute bouts of moderate-intensity exercise (i.e., stationary bicycle). Subjects will be provided a controlled dinner; the SI-informed bolus calculator will be used in the Experimental Admission while standard therapy will be used in the Control Admission. Subjects will then be observed overnight and discharged in the following morning.
This randomized, cross-over trial aims to assess changes in body weight, plasma lipids, insulin sensitivity, and postprandial metabolism with a low-fat, plant-based diet and a Mediterranean diet, both followed for 4 months.
Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.
The objective of this study is to assess whether intake of baked and then chilled potatoes over a 24-h period, compared to intake of isocaloric, carbohydrate (CHO)-matched foods low in fiber and resistant starch (RS), will increase insulin sensitivity, breath hydrogen and satiety, and decrease hunger and free fatty acid (FFA) levels in overweight or obese men and women at risk for metabolic syndrome and diabetes mellitus.
The hepatitis C virus is a major cause of chronic liver diseases, including cirrhosis and hepatocellular carcinoma, and infects approximately 3 % of the world population (150-170 million). It is estimated that approximately 80 % of patients with acute hepatitis C fail to eliminate the virus and become chronically infected Hepatitis C virus infection is strongly associated with the dysregulation of glucose homoeostasis such as insulin resistance and type 2 diabetes. Despite these findings of insulin resistance development via direct effects on insulin signalling pathway, the complex relationship between intrahepatic Hepatitis C virus infection and extrahepatic insulin resistance remains elusive. One of the countries most affected by Hepatitis C virus is Egypt. The Egyptian Demographic and Health Surveys measured antibody prevalence among the adult population aged 15-59 years at 10.0% in 2015—substantially higher than global levels. Several micro ribonucleic acids have been determined to play a key role in regulating viral replication and pathogenesis during infection. micro ribonucleic acid-122 expression is enriched in the liver, accounting for approximately 70 % of the total micro ribonucleic acid population in normal adult hepatocytes. Moreover, a particularly intriguing function of micro ribonucleic acid-122 involves its role in the Hepatitis C virus replication cycle. Antagonism of micro ribonucleic acid-122 not only reduces viral replication but also reduces Hepatitis C virus propagation by decreasing the expression of enzymes involved in lipid metabolism, which can enhance Hepatitis C virus replication in cell culture models.
