Filter by:The purpose of this study is to investigate the effects of chronic elevated growth hormone on metabolism and insulin sensitivity by studying acromegalic patients before and after treatment.
The purpose of this study is to further characterize the treatment related changes in insulin sensitivity, substrate metabolism and intrahepatic-intramyocellular lipids in patients with growth hormone deficiency (GHD).
Context: Upper body obese (UBO) subjects are more likely to develop cardiovascular disease (CVD) than lower body obese (LBO) or lean. This may in part be caused by greater hepatic secretion of very-low-density-lipoprotein-triglycerides (VLDL-TG). Objective: To assess the impact of body composition and insulin sensitivity on basal VLDL-TG turnover in women.
The purpose is to investigate the effects of 2 different treatments (drospirenone/ethinyl estradiol versus rosiglitazone) on insulin sensitivity and androgen levels, inflammatory markers, vascular markers and bone development in overweight adolescent females with polycystic ovary syndrome (PCOS).
The aim of the study is to test whether neutralizing TNF-alpha with infliximab affects insulin resistance and phenotypical manifestations of the metabolic syndrome as fasting plasma insulin, total body fat, plasma lipid profile or vascular endothelial function in obese male subjects.
This study is designed to compare the changes in insulin sensitivity as well as gastrointestinal hormone levels in diabetic and non-diabetic obese individuals who are undergoing weight loss procedures. The main hypothesis of this study is that weight loss induced by gastric bypass will induce a greater improvement in insulin sensitivity compared with gastric banding or low calorie diet. Subjects will be studied before and after weight loss. Studies consist of intravenous glucose tolerance test, body composition analysis, meal test, and energy expenditure.
We hypothesized that short-term treatment with AP drugs induces insulin resistance through a mechanistic route that is independent of weight gain and that atypical drugs exert stronger effects than typical compounds in this respect. We therefore treated healthy non-obese men with olanzapine (atypical AP) or haloperidol (typical AP) for 8 days, and studied the impact of these interventions on glucose and lipid metabolism by hyperinsulinemic euglycemic clamp, isotope dilution technology and indirect calorimetry.

Lifestyle and genetic factors interact in the development of obesity and the metabolic syndrome. The molecular mechanisms underlying the beneficial dietary modifications are, however, unclear. We aimed to examine the effect of the long-term 30 moderate weight reduction on gene expression in adipose tissue (AT) and to identify genes and gene clusters responsive to treatment and thereby likely contributing to the development of the metabolic syndrome. Thus, randomized controlled and individualized weight reduction and physical exercise intervention was conducted. In the WR group, glucose metabolism improved that was not seen in other groups. Moreover, an inverse correlation between the change in SI and the change in body weight was found (r =-0.44, p=0.026). Down-regulation of gene expression (p<0.01) involving gene ontology groups of extracellular matrix, cell death was seen. Such changes did not occur in the other groups.
The recent development of an oral carbohydrate drink for consumption prior to elective surgical procedures has been shown to improve insulin sensitivity. However, these studies have not investigated the use of this carbohydrate supplement in patients undergoing cardiac and spinal surgery. Hypothesis: The administration of 100g of carbohydrates the evening before and 50g of carbohydrates two hours before elective coronary artery bypass graft (CABG) or spinal surgery will reduce postoperative insulin resistance by 40% compared to those undergoing the standard of care of fasting the evening before and the day of surgery.
