Filter by:The objective in this project is to assemble a consortium of pediatric critical care centers of varying size, acuity, and composition to evaluate our glycemic control protocol on at least 250 children with hyperglycemia in different critical care units. ***This Study is supported by an R21 Grant (MRR) from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
The specific aim of this study is to identify the degree of correlation between real time subcutaneous glucose monitoring and intermittent glucose monitoring using capillary glucose samples, arterial blood samples and venous blood samples in critically ill surgical patients. A secondary aim will be to determine the accuracy of real time glucose monitoring.
The study intends on enrolling 48 subjects with diabetes. Diabetic subjects that no longer need insulin will be randomly placed (like the flip of a coin) on a diabetes pill called metformin, a diabetes pill called sitagliptin or a placebo pill (a pill without active medication). Subjects on pills will be followed for 3½ years and undergo blood tests at specified intervals to assess their ability to make insulin. These studies will allow a better understanding of the factors that lead to high blood sugar in patients with ketosis-prone diabetes mellitus (KPDM) and direct the best diabetes treatment for this patient population. Hypothesis: Metformin therapy or sitagliptin therapy compared to placebo, will improve β-cell function, insulin sensitivity, and allow for a longer period of time prior to encountering an insulin-deficient relapse after discontinuation of insulin therapy.
This is a prospective observational study to examine the levels of glucoregulatory hormones, with special focus on incretins levels, in critically ill patients with stress hyperglycemia.
Diabetes and Heart Failure are diseases with high morbidity and increased risk of death. Former investigations has shown that diabetes worsens the prognosis of heart failure. However it is uncertain how short term diabetic dysregulation in type 2 diabetics affect cardiac function. Our hypothesis is that short term dysregulation affects left ventricular function and exercise capacity in insulin treated type 2 diabetics with and without heart failure. To elucidate this hypothesis diabetic patients with and without heart failure will be investigated after overnight state of either high or normal blood glucose levels on two separate occasions. Metabolic and hormonal parameters will be measured. Systolic and diastolic cardiac function will be assessed, exercise capacity and post exercise regional myocardial tissue velocity as well as 6 minutes walk test will be investigated on both occasions. The study will be a randomized cross-over design.
Metabolic syndrome is directly related to obesity. This study investigated the use of a plant based formulation to improve on the condition of people with metabolic syndrome.
Both hypoglycemia and hyperglycemia can be detrimental to hospitalized patients. However, it is not clear which patients are more likely to develop significant problems with hypoglycemia or severe hyperglycemia in the hospital. Our hypothesis is that we will be able to identify risk factors present at admission that identify patients at greater risk of poor inpatient glycemic control
To demonstrate that a focused Emergency Department (ED) intervention for uncontrolled hyperglycemia enables safe and effective glycemic management and reduces emergency room re-visits. We assessed hypoglycemia BG < 60mg/dL; change in mean blood glucose and A1C, and ED revisits for hyperglycemia.
The overall goal of this proposal is to determine the effects of acute hyperglycemia and its modulation by Glucagon-like Peptide-1 (GLP-1) on myocardial perfusion in type 2 diabetes (DM). This study plan utilizes myocardial contrast echocardiography (MCE) to explore a) the effects of acute hyperglycemia on myocardial perfusion and coronary flow reserve in individuals with and without DM; and b) the effects of GLP-1 on myocardial perfusion and coronary flow reserve during euglycemia and hyperglycemia in DM. The investigators will recruit individuals with and without DM matched for age, gender and degree of obesity. The investigators will measure myocardial perfusion at rest and during vasodilator stress (to ascertain coronary flow reserve) while subjects are under controlled pancreatic clamp conditions during euglycemia (glucose ~100 mg/dl) and hyperglycemia (glucose ~250 mg/dl) in the presence and absence of concomitant GLP-1 infusion. The investigators believe that the translational significance of their studies is immense, impacting upon both acute and chronic cardiovascular disease manifestations. The effect of glycemic control on cardiovascular outcomes, morbidity and mortality remains an area of active investigation, fueled by the recent conflicting results of several large clinical trials (ACCORD, United Kingdom Prospective Diabetes Study (UKPDS), ADVANCE, VADT). If the investigators find that hyperglycemia is associated with altered myocardial perfusion, the mechanistic implications in the prevention and management of acute and chronic cardiovascular diseases in DM will be groundbreaking. Furthermore, if GLP-1 augments myocardial perfusion (as it does in the peripheral vasculature), the therapeutic benefits for prevention of cardiovascular events in this predisposed population are clear.
The purpose of this study is to analyze how common stress hyperglycaemia (abnormally high blood glucose) is in primary hip and knee replacement surgeries and which factors predispose to hyperglycaemia.
