Filter by:It's a randomized control trial to compare the effect of preoperative carbohydrate loading versus fasting on post operative insulin resistance after donor hepatectomy in terms of donor outcomes. Investigator will analyze the data and elucidate the value of post operative insulin resistance in reducing the occurrence of complications, length of hospital stay and fastening the recovery in donors of Live donor liver transplantation.
The aim of this study is to determine the effect of 3 months supplementation of lyophilize dried cornelian cherry (Cornus mas L.) on women diagnosed with insulin resistance. The baseline and end biochemical parameters and anthropometric measurements will be compared with control subjects.
The purpose of this project is to determine if hyperinsulinemia attenuates sympathetic nervous system-mediated vasoconstriction in the human leg.
The objective is to determine if how physical fitness, measured using a treadmill maximal oxidative capacity test, is associated with the capacity to metabolize a high-fat meal in pediatrics (ages 8-17 years). Ability to metabolize the meal will be assessed by profiling mitochondrial and extra-mitochondrial fatty acid metabolites. The investigators will test if fatty acid oxidation mediates the relationship between fitness and markers of metabolic health, such as insulin resistance.
The purpose of this study is to investigate the effect of whole body vibration on insulin resistance in females with polycystic ovarian syndrome
The investigators aim to evaluate whether and to what extent glucose tolerance, beta cell function, insulin clearance, and glucose metabolic fluxes change in response to an acute increase in plasma triglycerides during lipid infusion, independently of free fatty acid (FFA) levels, in nondiabetic subjects.
The popularity of marathons and endurance events has increased over the last few decades and, interestingly, the demographics of participants have also changed. From 1980 to 2002 the average race time to complete the marathon lengthened from ~3.5 hours to ~4.5 hours. Likewise, many endurance races include "Clydesdale" and "Athena" divisions for heavier weight male and female runners, respectively. As such, there has been an increase of overweight and obese participants in these races. For example, one study consisting of 250 runners determined, according to BMI, that approximately 15% and 31% of the female and male participants, respectively, were classified as overweight, with 31% and 33% classified as obese. Therefore, many recreational endurance athletes are overweight despite their high level of activity. On one hand, these data are positive as regular exercise reduces cardiovascular disease and all-cause mortality in overweight and obese populations. Yet, it is well documented in sedentary obese individuals that excess adiposity can lead to disturbances in adipocyte lipolysis and altered substrate utilization at rest and during exercise, and can decrease muscle quality. However, it is unknown if overweight individuals that exercise regularly have disrupted fat metabolism, circulating hormones, or muscle quality. No study has directly determined if differences exist in fat metabolism, circulating hormones, and muscle quality between overweight recreational female athletes and their lean counterparts when training status is equivalent. Therefore, the purpose of this investigation is to determine if differences in pre and post-exercise fat metabolism, circulating insulin and growth hormone, and muscle quality exist between active overweight individuals compared to active lean individuals with similar training history and who have regularly trained for and participated in endurance events within the last few years.
PURPOSE: to determine the effect of aerobic exercise training and diet on sex hormones , insulin resistance and depression and if is there correlation between these factors effect in postmenopausal obese women BACKGROUND: The practice of regular physical activity is recommended worldwide by different public health agencies for primary or secondary prevention of many health problems, including cancers. In particular, physical activity is associated with a 25 % reduction in the average risk of cardiovascular diseases among women, and this protective effect appears to be independent of menopausal status. Many interrelated biological mechanisms may underlie this association, such as the effect of physical activity on glucose metabolism, inflammation, immune function, and sex hormones. Indeed, endogenous sex hormones, particularly estrogens, seem to be involved in the initiation, promotion, and progression of tumors. Prolonged exposure to high endogenous hormone levels is considered one of the main risk factors for female breast cancer, with a relative risk of 2.00 (95 % confidence interval (CI): 1.47-2.71) for postmenopausal women with the highest estradiol levels . Several observational studies have found an inverse association between physical activity and circulating estrogen levels . This effect may be mediated by the decrease in fat mass, the main source of estrogens in postmenopausal women. It may also be mediated by the disruption of the menstrual cycle before menopause , especially when exercise is associated with low energy intakes. However, the assessment of the exposure to physical activity remains imprecise, because it is generally only possible to measure it in naturally living subjects using questionnaires . HYPOTHESES: may have no Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women RESEARCH QUESTION: Is there Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women?
The main aim of the study is to collect preliminary information on the feasibility and efficacy of a time restricted eating intervention in Spanish children and adolescents with obesity and metabolic comorbidities. Two 8-week interventions will performed in a randomized crossover controlled design: a) reduction of the habitual eating window; b) standard care. Different measurements of body composition and cardiometabolic health markers will be performed along those weeks.
The purpose of this study is to demonstrate the efficacy of pasteurized Akkermansia muciniphila (pAKK) in improving insulin sensitivity in hyperglycaemic, but otherwise healthy persons with metabolic syndrome. This is the primary objective of this study. Secondary objectives consist of evaluation of the effects of next generation beneficial microbes on metabolic health, anthropometry and body composition, and safety. Therefore, the trial is designed as a phase 2, randomized, double-blind, placebo-controlled, parallel group, multi-center trial comparing pAKK with placebo in restoring insulin sensitivity in dysglycaemic but otherwise healthy subjects with metabolic syndrome. In total, 144 enrolled participants will attend 6 study visits in total. Study visits may be conducted in the clinic, at home by a Healthcare Professional, or by telephone / telemedicine.
