Active clinical trials for "Insulin Resistance"

The aim of the present study is to evaluate the implication of adipokines, inflammation, insulin resistance and endothelial dysfunction in the pathogenesis of preeclampsia and in pregnancy related complications.

In 2012, a cross-sectional survey sampling 1,966 community-dwelling old people was conducted. Structurized questionnaires were interviewed face-to-face by well-trained staffs. An overnight fasting blood were obtained for biochemistry parameters.

We investigate the association between Triglyserid-Glucose(TyG) index and prostate cancer in patients undergoing radical prostatectomy.

Insulin resistance is a positive protective reaction against surgery .this resistance has some negative consequences for patient health. It is associated with infectious complications. At the same time, Postoperative insulin resistance has been shown to correlate with the length of postoperative stay in hospital. Recently several clinical studies have shown that a carbohydrate-rich drink given 2 h before surgery diminishes postoperative insulin resistance in patient. The aim of our study is to investigate the influence on insulin resistance in patient with diabetes.

Hepatic steatosis and insulin resistance are associated with severity of fibrosis in non-alcoholic fatty liver disease (NAFLD) and chronic hepatitis C. However, clinical significance of steatosis and insulin resistance on fibrosis in chronic hepatitis B (CHB) is not well established. The aim was to investigate the relationship between insulin resistance, hepatic steatosis, and fibrosis in patients with CHB.

Under chronic immunosuppressive and corticosteroid therapy, transplant patients have a tendency to develop in the long-term diabetes. Patients who have received extra pancreatic tissue with their liver and small bowel transplantation have not yet developed insulin resistance or diabetes mellitus. We would like to investigate to which level insulin secretory capacity the extra pancreas together with the native pancreas has in these transplant patients using the hyperglycemic clamp. These data will be compared with the data obtained from healthy controls.

The purpose of this study is to evaluate the degree of beta-cell dysfunction among participants with type 2 diabetes and the association between beta-cell dysfunction and demographic, clinical, and treatment variables.

The investigators specific aim is to compare the relationship between systemic fatty acid availability and insulin sensitivity in a relatively homogenous population of obese adults. The investigators anticipate 1) greater systemic fatty acid availability will be associated with lower insulin sensitivity and 2) greater systemic fatty acid availability will be associated with greater accumulation of fatty acid intermediates and pro-inflammatory markers.

The overall objectives of this study are to examine the relationships between circulating vitamin D, insulin sensitivity, and multiple indices of vascular function and to examine whether vitamin D deficiency in African Americans (AA) and White Hispanics (WH) is responsible for ethnic differences in insulin sensitivity and hypertension in AA, WH and European Americans (EA), as well as mechanisms underlying the association between insulin resistance and blood pressure. We hypothesize that 1) serum 25(OH)D is associated with insulin sensitivity and vascular functioning, independent of adiposity, 2) lower insulin sensitivity and vascular functioning in AA and WH relative to EA is due to lower circulating 25(OH)D in AA, and 3) the relationship between insulin resistance and vascular dysfunction is mediated by 25(OH)D. Acronyms: African American (AA), European American (EA), White Hispanics (WH), Serum 25-hydroxy vitamin D (25()H)D, Body mass index (BMI), Alabama (AL).

The investigators evaluated predictive values of myocardial fatty acid metabolism and insulin resistance for cardiac death of hemodialysis patients with normal coronary arteries.
