OBJECTIVE To examine the long-term relationship between sleep duration and type 2 diabetes or impaired glucose tolerance (IGT). METHODS Body composition measurements and self-reported sleep duration were determined in a longitudinal sample of 276 individuals aged 21 to 64 years followed for a mean of 6 years. Risk factors of type 2 diabetes/IGT over the follow-up were determined and relative ...

OBJECTIVE We compared and contrasted cardiovascular disease (CVD) risk factors, subclinical manifestations of CVD, incident coronary heart disease (CHD), and all-cause mortality by categories of impaired glucose regulation in nondiabetic individuals. RESEARCH DESIGN AND METHODS The study included 6,888 participants aged 52-75 years who had no history of diabetes or CVD. All-cause mortality an...

OBJECTIVE The Diabetes Prevention Program (DPP) reported no racial/ethnic differences in the incidence of diabetes in individuals with impaired glucose tolerance (IGT). Therefore, it has been hypothesized that factors associated with racial/ethnic disparities act prior to the development of IGT. Because impaired fasting glucose (IFG) and obesity were also very prevalent in the DPP, we examined ...

Impaired cardiac systolic and diastolic function has been observed in preclinical models and in subjects with type 2 diabetes. Using a recently validated positron emission tomography (PET) imaging method with 14(R,S)-[(¹⁸F]-fluoro-6-thia-heptadecanoic acid to quantify organ-specific dietary fatty acid partitioning, we demonstrate in this study that overweight and obese subjects with impaired gl...

OBJECTIVE This study evaluated the nerve conduction study (NCS) parameters of the most distal sensory nerves of the lower extremities-namely, the medial dorsal cutaneous (MDC), dorsal sural (DS), and medial plantar (MP) nerves-in diabetic (DM) and impaired glucose tolerance (IGT) patients who displayed normal findings on their routine NCSs. RESEARCH DESIGN AND METHODS Standard NCSs were perfo...

OBJECTIVE To investigate the characteristics of isolated impaired glucose tolerance (IGT) and isolated impaired fasting glucose (IFG), we analyzed the factors responsible for elevation of 2-hour postchallenge plasma glucose (2 h PG) and fasting plasma glucose (FPG) levels. METHODS We investigated the relationship between 2 h PG and FPG levels who underwent 75 g OGTT in 5620 Japanese subjects ...

OBJECTIVE To assess small and large nerve fiber function in people with normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS Participants were recruited consecutively from a population-based cohort: NGT (n = 39), IGT (n = 29), and T2D (n = 51). Electrophysiological measures included nerve conduction studies and thermal thresh...

The image grand tour (IGT) is a method for visualizing multi– spectral images or multiple registered images. The IGT projects a linear combination of the pixel vectors into one– dimensional space (for each pixel) and renders these projected values as a gray–scale image. We will present a JAVA–based version of the IGT with additional software enhancements such as the capability of zooming into a...

Background: Annual screening for CF diabetes (CFD) is recommended from aged 10 years. A 2 hour blood glucose (BG) reading on OGTT of >11.1 mmol/l diagnostic CFD, however data incidence impaired tolerance (IGT) are limited. Continuous monitoring (CGM) alongside regular diet better defines daily BG excursions aiding interpretation glycaemic control. UK guidelines recommend both & CGM as suitable ...

Background & Aims: The aim of this study was to estimate the prevalence and risk factors for diabetes, pre-diabetes and metabolic syndrome in first-degree relatives(FDRs) of patients with type 2 diabetes. Methods: In a cross-sectional study between 2003 and 2005, 3228 of first-degree relatives of patients with type 2 diabetes (841 men and 2387 women) from Isfahan Endocrine and Metabolism Resear...
