Thiazolidinediones are a powerful and clinically important new class of oral antidiabetic agents that act by improving insulin sensitivity. Troglitazone is the prototype drug in this class but was withdrawn from the market in March 2000 due to its association with idiosyncratic hepatotoxicity. Currently two thiazolidinediones, rosiglitazone and(More)
The aim of the study was to determine whether a recommendation to walk 10000 steps per day would result in significant improvements in glycemic control, insulin sensitivity, and cardiovascular risk in patients with type 2 diabetes mellitus. The study was a 6-week randomized controlled trial that included 30 patients with type 2 diabetes mellitus. After 10(More)
Achieving target glycaemic goals while avoiding hypoglycaemia is a major challenge in the management of elderly patients with diabetes mellitus. Repeated episodes of hypoglycaemia may cause extreme emotional distress in such patients, even when the episodes are relatively mild. Moreover, evidence is mounting that hypoglycaemia among elderly patients is a(More)
Weight-loss interventions generally improve lipid profiles and reduce cardiovascular disease risk, but effects are variable and may depend on genetic factors. We performed a genetic association analysis of data from 2,993 participants in the Diabetes Prevention Program to test the hypotheses that a genetic risk score (GRS) based on deleterious alleles at 32(More)
OBJECTIVE Lispro is a newly FDA-approved analog of human insulin that will be widely used in patients with IDDM. This insulin, however, may have an increased potential for hypoglycemia because of its very rapid subcutaneous absorption, especially in a setting of decreased carbohydrate intake. Using a short-term prospective randomized parallel group-study(More)
Lispro insulin is the first synthetic insulin analog commercially available for the treatment of diabetes. Its rapid absorption and short half-life results in both advantages and disadvantages to the patient with diabetes. Understanding the physiology of normal insulin secretion and the pathophysiology of diabetes is paramount to optimizing Lispro insulin(More)
OBJECTIVE To explore the hypothesis that CD36, a scavenger receptor and fatty acid translocase, is upregulated in peripheral blood mononuclear cells (PBMCs) among patients with type 2 diabetes and is a biomarker of PBMC activation and inflammation. RESEARCH DESIGN AND METHODS We used a cross-sectional observational design to study a multi-racial/ethnic(More)
Glycemia varies widely in patients with diabetic ketoacidosis (DKA), with plasma glucose concentrations between 10 to 50 mmol/L commonly encountered. The mechanism of this glycemic variability is uncertain. Our study examined the differential effects of fasting and dehydration on hyperglycemia induced by withdrawal of insulin in type 1 diabetes. To evaluate(More)
CONTEXT Retrospective studies have identified oral sulfonylureas, age, and fasting as major risk factors for hypoglycemia in patients with type 2 diabetes. Sulfonylureas may be withheld from elderly patients out of concern for hypoglycemia. OBJECTIVE To evaluate the hypoglycemic effects of maximum doses of once-daily second-generation sulfonylureas(More)
The primary empty sella syndrome is a common radiographic finding that is rarely associated with clinical pituitary dysfunction. Studies using dynamic endocrine testing, however, have shown altered pituitary reserve in some patients with the primary empty sella syndrome. We describe a patient with a primary empty sella and an isolated deficiency of(More)
