BACKGROUND: Recently, we showed that in subjects with a body mass index (BMI) >35 kg/m2 waist circumference (WC) is associated with metabolic traits but associations were weaker in men than in women. AIMS: To confirm our previous observation that anthropometric measures of abdominal obesity are closer linked to metabolic traits in obese women than obese men. To test whether sagittal abdominal diameter (SAD) provides a better prediction of metabolic traits in obese subjects than WC related measures...

Monogenic diabetes represents a heterogeneous group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes into neonatal diabetes or maturity onset diabetes of the young (MODY) according to age of onset, not every case can be classified into those 2 groups. We evaluated patients with monogenic diabetes diagnosed during the last 10 year period. Type 1 DM, MODY, and patients with negative autoantibodies and no mutation in a known gene were excluded from the study...

Background and objective Soccer is associated with repetitive head trauma, which, as it is known from sports like football and boxing, can result in hypopituitarism. Gonadotropins and GH are the most common pituitary hormones to become deficient. GH deficiency is associated with an increased risk of cardiovascular mortality and has negative influence on body mass index, visceral fat mass, insulin resistance and sensitivity, bone mineral density and inflammatory markers. Therefore the aim of this study was to evaluate the somatotrope pituitary function in professional soccer players...

The increasing prevalence of childhood obesity is a driving force behind the increase in adolescent's metabolic syndrome (MetS). Although there is no clear consensus about the pediatric definition for MetS, this syndrome is becoming very common among adolescents. It is characterized by insulin resistance (IR), dyslipidemia, abdominal obesity and hypertension, and is associated with a high risk of type 2 diabetes mellitus and CVD in adulthood. Due to the increasing prevalence of obesity, there is strong incentive to reduce the impact of the adverse health effects associated with MetS...

Metabolic syndrome is a cluster of metabolic abnormalities including central obesity, hyperglycemia, hypertension, and dyslipidemia. A previous study has established that high-carbohydrate high-fat diet (HCHF) can induce MetS in rats. In this study, we modified components of the diet so that it resembled the diet of Southeast Asians. This study aimed to determine the effects of this modified HCHF diet on metabolic parameters in rats. Male Wistar rats (n=14) were randomised into two groups. The normal group was given standard rat chow...

Free fatty acids (FFAs) participate in a variety of physiological functions. FFAs are associated with the development of type 2 diabetes mellitus (T2DM). Uyghurs and Kazaks have a different prevalence of T2DM, which cannot be explained by traditional risk factors. This study aimed to examine FFAs as potential biomarkers to distinguish between healthy and T2DM Uyghurs and Kazaks. This was a prospective study conducted at the Xianjiang Medical University from 01/2007 to 06/2010 in Uyghurs and Kazaks. The subjects were grouped as T2DM patients (Uyghurs: n=39; Kazaks, n=21) and controls (Uyghurs: n=35; Kazaks, n=40)...
