Chronic Hepatitis C and Insulin Resistance
Hepatitis CInsulin ResistanceChronic hepatitis C (CHC) is among the commonest chronic infectious disease in Australia with >200,000 exposed persons. Amongst non-infectious chronic conditions- Type 2 diabetes, obesity and heart disease are extremely common. This study will examine the relationship between insulin resistance, fat deposition in the liver, muscle and abdomen, and liver injury due to CHC
Diabetes Genome Project: A Prospective Registry to Identify Genetic Variation Among Diabetic Patients...
Diabetes MellitusInsulin Resistance1 morePrevious scientific research has found multiple genes that affect the risk for developing heart disease or complications during the treatment of heart disease. Less is currently known about how patients with heart disease may differ on the basis of other ailments they may have and how these other ailments may affect their treatment and prognosis. For this reason, researchers at the Mid America Heart Institute are conducting this research to find out how genes affect heart disease and recovery following angioplasty. The study will include patients with diabetes in order to determine if their genes are different from patients without diabetes. A total of 1,607 patients were enrolled. There were 2 groups of patients selected for this study. The first group of patients included into the study will be those that are scheduled to have a diagnostic angiogram only. The second group of patients were those that had along with the angiogram a percutaneous transluminal coronary angioplasty, PTCA and or the use of a device called a coronary "stent", designed to help prop open the artery and to help avoid collapse. Samples for both groups will be stored for 30 years. After this time, all samples will be destroyed. Ultimately, we are hopeful that we will identify genes that will identify groups of patients at risk for heart disease.
Insulin Resistance and Hypertensive Disorders in Pregnancy
Hypertension in PregnancyDiabetes Mellitus in PregnancyThe purpose of this study is to determine whether insulin resistance might affect the pathogenesis of hypertensive disorders in pregnancy since midtrimester. Furthermore, markers of vascular and placental injuries, of oxidative stress and inflammation will be evaluated.
Effect of HCV Infection on Insulin Resistance and Malnutrition-inflammation Complex Syndrome in...
Hepatitis CHemodialysis3 moreThe purpose of this study is to study whether hepatitis C virus (HCV)infected maintenance hemodialysis (MHD)patients have distinct metabolic, inflammatory and adipokine characteristics that can be linked to poor clinical outcome and to examine the hypothesis that HCV infected MHD patients with metabolic syndrome have higher risks for hospitalization, cardiovascular and all-cause mortality.
Prospective Observation Study of Insulin Sensitivity During and After Gonadotropin Releasing Hormone...
Prostate CancerThe purpose of this research study is to find out if a certain type of hormone therapy, gonadotropin-releasing hormone agonist (GnRH agonist), affects the way the body produces and responds to insulin. The investigators will evaluate the changes in insulin sensitivity during and after GnRH agonist treatment for prostate cancer. The investigators are assessing the possibility that treatment-related insulin resistance may contribute to the risk of diabetes and/or cardiovascular disease in men with prostate cancer.

Sleep, Glycemic Control, and Insulin Resistance in Adolescents With Type 1 Diabetes
Type1diabetesAdolescent Behavior1 moreDespite advancements in care, most adolescents with T1D have higher BMI and significantly higher HbA1c than recommended and are markedly IR, placing them at increased risk for CVD1,2. Thus, alternative approaches to improve and maintain glycemic control, IR, and BMI for adolescents with T1D are urgently needed. This proposal moves beyond the current insulin and carbohydrate counting-focused lifestyle change paradigm to focus on sleep and circadian misalignment, which will allow for identification of new mechanisms that can be directly translated into future intervention and prevention trials. The goal of the current study is to utilize multiple objective measures of sleep duration, timing (actigraphy), and circadian rhythm (melatonin) in adolescents with type 1 diabetes (T1D; N = 40) and examine relationships with glycemic control, IR, vascular health, and BMI. Further, qualitative methodology will be used to identify barriers and facilitators to healthy sleep in adolescents with T1D.
Development of a Novel Method to Measure Insulin Sensitivity in Humans: A Pilot Study
Insulin SensitivityThis study will determine whether the ratio between 24h C-peptide urinary excretion rate and average 24h circulating glucose represent a good correlate of what is measured by the gold standard, i.e. M (glucose disposal rate) from a euglycemic-hyperinsulinemic clamp
Conventional and Metabolomic Predictors of Prediabetes & Insulin Resistance
PreDiabetesObesity1 moreThe purpose of this study is to evaluate the longitudinal test performance of an array of conventional biomarkers of glycemia, including Hemoglobin A1c (HbA1c), and novel metabolomic biomarkers for identifying progression of glucose tolerance (normal to prediabetes or prediabetes to diabetes) in an overweight and obese pediatric cohort.
Determining of Normal Values and Conformity Assessment of the Dosage of a Plasmatic Marker of the...
Insulin ResistanceThe purpose of this study is on one hand to verify the measurement conformity of the IRAP dosage and on the other hand to obtain normal values of the blood IRAP concentration on healthy volunteers.
