Filter by:This study is to determine whether different types of resistant starch have different effects on blood glucose in healthy adults.
The purpose of this study is to evaluate safety and accuracy of the IVBG System (the "System") when used to track blood glucose in insulin treated subjects with diabetes mellitus in an in-clinic setting for up to 72 hours (per subject). Reference blood glucose measurements will be collected across the entire reportable range of the System (e.g., 40 400 mg/dL) with adequate sampling at the upper and lower ends of this range. IVBG System accuracy will primarily be assessed relative to ISO 15197 criteria (i.e., within ±15 mg/dL at YSI glucose levels < 75 mg/dL, and within ±20% at YSI glucose levels >75 mg/dL).
Primary Aim: To test the acute effects of olanzapine or ziprasidone administration, in comparison to placebo, on insulin sensitivity in antipsychotic-naïve healthy young men, measured as whole-body dextrose infusion rates (mg/kg/min), hepatic glucose production (glucose rate of appearance [Ra]), primarily muscle glucose utilization (glucose rate of disappearance [Rd]), and adipose tissue related free fatty acid production (glycerol rate of appearance [Ra]). We hypothesize that olanzapine, but not ziprasidone, will result in acute decreases in insulin sensitivity. Secondary Aim: To test the acute effects of olanzapine or ziprasidone on insulin signaling pathways in antipsychotic naïve healthy young men. We hypothesize that olanzapine, but not ziprasidone, will result in acute alterations in insulin signaling.
This is a medical research study designed to see if an infusion of a naturally occurring hormone, GLP-1, works when used to decrease blood sugar during cardiac surgery.
The purpose of this project is to study if intravenous Exenatide is effective at maintaining normal blood glucose levels and preventing low blood glucose levels during surgery.
It is currently standard of care in many Medical and Surgical ICU's to institute a nurse driven insulin protocol in maintaining tight glucose control in the critical patient. Many articles have been written to address this topic. However, there is no current data regarding the use of glycohemoglobin as a marker of risk of morbidity and mortality. In our study we would like to determine whether or not the HbA1C could be used as a marker of morbidity and mortality. The HbA1C is a simple blood test that may be added on to any CBC collection tube; a blood sample that critical patients have drawn up to several times a day. The investigators would analyze this information in respect to the rest of the clinical data collected regarding the patient's illness.
The incretin hormone glucagon-like peptide-1 (GLP-1) has known insulinotrophic and glucagonostatic properties. However, inpatients with type 2 diabetes mellitus (T2DM)it is shown, that the beta cell sensitivity towards GLP-1 is decreased, when comparing to healthy controls. Further, these patients have decreased GLP-1 response to a meal. The aim of this study is to elucidate if the diabetic hyperglucagonemia, seen in these patients both during fasting and in a postprandial condition, is coursed by a decreased sensitivity to GLP-1 in the diabetic alpha cell. Ten T2DM patients and ten matched healthy control subjects will be examined on two separate days. Day 1: increasing GLP-1 infusions and Day 2: saline. During both days plasma glucose (PG) will be clamped at fasting level (FPG). Patients with T2DM will be submitted til a Day 3, here PG will be normalized over-night by an adjustable insulin infusion, on the following day the GLP-1 infusion of Day 1 will be repeated. The hypothesis is that these patients have decreased alpha cell sensitivity to GLP-1 as is the case with the beta cell sensitivity. This decreased sensitivity, the investigators speculate, contributes the defect suppression og glucagon and thereby to the increased PG levels seen in T2DM. Further the investigators will elucidate if this sensitivity can be increased by normalizing the diabetic PG to a normal FPG level.
The aim of the investigators study was to compare for the first time efficacy and safety of intravenously administered GLP-1 with an established intravenous insulin regimen in hyperglycaemic type 2 diabetic patients.
Hyperglycemia is very common among critically ill patients, even in the absence of diagnosed diabetes or pre-diabetes. We aimed to determine the prevalence of occult glucose metabolism abnormalities in a general intensive care unit (ICU) and hypothesized that hyperglycemia severity, as reflected by insulin requirements for maintenance of normoglycemia, could be used as a tool to identify high risk patients.
Treat-to-target trial of basal Insulin in Post-transplant hyperglycemia (TIP): efficacy and safety of a novel protocol in renal transplant recipients receiving a tacrolimus-based immunosuppression DESCRIPTION: A prospective, randomized safety and efficacy study of long-acting insulin (Insulatard®) as therapy against post-transplant hyperglycemia in renal transplant recipients OBJECTIVES: Primary Objective: To demonstrate superiority of long-acting insulin (Insulatard®) against post-transplant hyperglycemia, in comparison to conventional treatment, and as evaluated by HbA1c Secondary Objectives: - To assess the average post-transplant glucose levels in renal transplant patients under conventional blood-glucose lowering therapy during a period of at least 14 days after transplantation by measuring the capillary blood glucose levels four times daily in both groups of patients (fasting, before lunch, before supper, after supper) - To detect the number of post-transplant patients who - without any history of pre-transplant diabetes - develop at least one episode of post-transplant hyperglycemia (> 140 mg/dl before supper) - To detect the average number of hyperglycemic episodes in post-transplant patients with at least one episode of post-transplant hyperglycemia and without any history of diabetes - To assess the amount of (long-acting) insulin (in IU) needed in order to obtain a target capillary blood glucose level in the range of 110 mg/dl to 120 mg/dl before supper in post-transplant patients with incidence of hyperglycemia - To assess the safety of long-acting insulin in controlling post-transplant hyperglycemia (especially with regards to episodes of hypoglycemia (glucose-level < 60 mg/dl) - To assess the prevalence of post-transplant diabetes, as diagnosed by an abnormal oral glucose tolerance on days 90, 180 and 360 after transplantation, in the group of patients which has been treated with long-acting insulin, in comparison to patients who received conventional treatment - To assess the morbidity (hospitalization, infections, subsequent episodes of surgery, requirement of non-immunosuppressive, non- blood glucose lowering medication) in the group of patients with long-acting insulin for hyperglycemia, in comparison to patients randomized into the group receiving conventional treatment - To assess the renal outcome (creatinine levels, rejections) in the group of patients which is foreseen to be treated with long-acting insulin for hyperglycemia, in comparison to patients randomized into the group receiving conventional treatment
