BACKGROUND The aim of this study was to analyze the prevalence and clinical characteristic of the metabolic syndrome of adults, over 40 years old, living in Korea. METHODS This study was carried out for 2 years, 2003-2004, on total 5,330 individuals (2,197 men and 3,133 women) selected by the stratified random cluster sampling among adults over 40 years(More)
OBJECTIVE We aimed to determine the effects of thyroid hormone on A1C and glycated albumin (GA) in nondiabetic patients with overt hypothyroidism. RESEARCH DESIGN AND METHODS A1C levels were measured in 45 nondiabetic patients with overt hypothyroidism and 180 euthyroid control subjects. A1C, GA, fasting blood glucose (FBG), 1,5-anhydroglucitol, and(More)
OBJECTIVE This study was conducted to investigate the association of diabetic peripheral neuropathy (DPN) with both arterial stiffness and intima-media thickness (IMT). RESEARCH DESIGN AND METHODS We conducted a cross-sectional analysis of 731 subjects with type 2 diabetes. DPN was diagnosed on the basis of neuropathic symptoms, insensitivity to a 10-g(More)
BACKGROUND Although many anti-diabetic drugs have been used to control hyperglycemia for decades, the efficacy of commonly-used oral glucose-lowering agents in Korean type 2 diabetic patients has yet to be clearly demonstrated. METHODS We evaluated the efficacy of glimepiride, metformin, and rosiglitazone as initial treatment for drug-naïve type 2(More)
There is controversy regarding definition of vitamin D inadequacy. We analyzed threshold 25-hydroxyvitamin D (25[OH]D) below which intact parathyroid hormone (iPTH) increases, and examined age- and sex-specific changes of 25(OH)D and iPTH, and association of 25(OH)D and iPTH with bone mineral density (BMD) in elderly Koreans. Anthropometric parameters,(More)
BACKGROUND Hypoglycemia is a very serious complication in patients with type 2 diabetes mellitus (T2DM) and affects the economic burden of treatment. This study aims to create models of the cost of treating hypoglycemia in patients with T2DM based upon physician estimates of medical resource usage. METHODS Using a literature review and personal advice(More)
BACKGROUND This study aimed to compare the patterns of insulin secretion and resistance between Korean subjects in the 1990s and 2000s. METHODS Insulin secretion and resistance indices were calculated from subjects who underwent 75-g oral glucose tolerance tests in the year 1997 to 1999 and 2007 to 2011 at the Seoul St. Mary's Hospital, Korea. RESULTS A(More)
BACKGROUND The present study was designed to develop criteria for screening patients with type 2 diabetes mellitus (T2DM) for asymptomatic coronary artery disease (CAD). METHODS A total of 213 patients with T2DM without typical angina or chest pain were studied between 2002 and 2007. We also evaluated 53 patients with T2DM who had reported chest(More)
The tongue consists of a complex, multiscale array of myofibers that comprise the anatomical underpinning of lingual mechanical function. 3-D myoarchitecture was imaged in mouse tongues with diffusion spectrum magnetic resonance imaging (DSI) at 9.4 T (b(max) 7000 smm, 150-microm isotropic voxels), a method that derives the preferential diffusion of(More)
We studied the efficacy and safety of acarbose in comparison with voglibose in type 2 diabetes patients whose blood glucose levels were inadequately controlled with basal insulin alone or in combination with metformin (or a sulfonylurea). This study was a 24-week prospective, open-label, randomized, active-controlled multi-center study. Participants were(More)
