AIMS To evaluate the performance of fasting plasma glucose (FPG) in determining the need for a full oral glucose tolerance test (OGTT) to diagnose gestational diabetes (GDM) by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. METHODS A multicenter cohort study of 4926 pregnant women 20 years or older consecutively enrolled in prenatal care clinics of the...

The oral glucose tolerance test (OGTT) used for the diagnosis of Cystic Fibrosis Related Diabetes (CFRD) is inconvenient and requires a great deal of patient cooperation. Other investigations such as measuring fasting glucose and glycosylated haemoglobin (HbA1c) concentrations, could offer several practical advantages over the OGTT for diabetic screening. To investigate the ability of these tes...

The oral glucose tolerance test and arginine infusion test were carried out on 22 patients with chronic pancreatitis and 11 normal control subjects. According to the glucose tolerance curve, the patients were divided into three groups; group I (normal or slightly impaired), group II (mildly diabetic) and group III (moderately diabetic). Markedly impaired insulin responses to oral glucose as wel...

objective: to evaluate the prevalence of gestational diabetes mellitus (gdm) and its risk factors in tehran. materials and methods: from march 2002 to october 2004, screening for gdm was performed on 1804 women in tehran. all pregnant women were referred for a 50 g oral glucose challenge test (ogct) between 24th and 28th week of gestation. all subjects with an abnormal gct (blood glucose level ...

We examined the relation between stress reactivity and 24 h glycemic control in 17 inactive, healthy older people (≥60 years) under both a novel psychophysical stress and a seated control condition. Plasma cortisol was measured over the course of the stress and recovery periods. Glycemic control was determined over the subsequent 3 h from an oral glucose tolerance test (OGTT) and over 24 h via ...

Delphinidin anthocyanins have previously been associated with the inhibition of glucose absorption. Blood glucose lowering effects have been ascribed to maqui berry (Aristotelia chilensis) extracts in humans after boiled rice consumption. In this study, we aimed to explore whether a standardized delphinidin-rich extract from maqui berry (Delphinol) affects glucose metabolism in prediabetic huma...

The purpose of this study was to determine the effects of high intensity/ low volume (HILV) and low intensity/high volume (LIHV) isokinetic resistance exercise on postexercise glucose tolerance. Subjects (n = 10) participated in a counterbalanced, randomized design of 2 separate isokinetic resistance exercise trials (HILV and LIHV) of reciprocal concentric knee flexion and knee extension in a f...

The authors assessed the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) according to the 1980 National Diabetes Data Group (1980 NDDG) classification and diagnosis. Two hundred and sixty inhabitants [aged 50.9 +/- 9.6 years, male: female (M:F) = 90: 170] of five small rural towns in Kumamoto Prefecture (population 1.8 million) and 279 male members of western divisions...

INTRODUCTION Several studies have assessed the impact of the 1997 American Diabetes Association (ADA) recommendation, of using fasting plasma glucose (FPG) concentration, to diagnose diabetes mellitus in population-based cohorts. However, data concerning the impact of this recommendation in the hospital setting are limited. As the performance characteristics of diagnostic tests vary depending o...

Glycated haemoglobin (HbA(1c)) is considered the 'gold standard' for monitoring metabolic control in diabetes. An International Expert Committee recently recommended HbA(1c) as a better method than measurement of glucose to use in the diagnosis of diabetes, based on its strong association with microvascular complications, a lower day-to-day variability and ease of use, not necessarily in the fa...
