BACKGROUND Previous studies have assessed the metabolic changes and lifestyles associated with overweight adolescents. However, these associations are unclear amongst overweight adolescents who have already developed insulin resistance. This study assessed the associations between insulin resistance and anthropometric, metabolic, inflammatory, food consumption, and physical activity variables a...

BACKGROUND Tumour necrosis factor alpha (TNFalpha) may be an important mediator of insulin resistance. Infliximab is a chimeric monoclonal, high affinity antibody against the soluble and transmembrane TNFalpha, which can reduce markedly the biological activity of circulating and tissue TNFalpha and is used to treat various autoimmune disorders. OBJECTIVE To assess the effects of infliximab in...

INTRODUCTION Previous studies have shown that hormonal factors such as levels of insulin, cortisol, testosterone, and insulin resistance are related with increased nephrolithiasis (NL). However, no previous study has evaluated the relationship between insulin, insulin resistance, thyroid hormones, cortisol, intact parathyroid hormone and testosterone levels with the presence of NL in a comprehe...

Background: The earliest detectable abnormality in diabetes mellitus type II (DM II) is the impairment of body’s ability to respond to insulin, necessitating extra insulin secretion in an attempt to stimulate the desensitized cells. Obesity is considered as the single most important, reversible, causative environmental factor for insulin resistance (IR) aggravating the metabolic disturbance in ...

BACKGROUND The aim of the study was to estimate the association between anthropometric obesity parameters, serum concentrations of ghrelin, resistin, leptin, adiponectin and homeostasis model assessment (HOMA-IR) in obese non-diabetic insulin-sensitive and insulin-resistant patients. MATERIAL/METHODS Study subjects included 37 obese (body mass index [BMI] ≥ 30 kg/m2) out-clinic patients aged ...

The purpose of the present study was to evaluate the effect of Ramadan fasting on insulin sensitivity in subjects with the metabolic syndrome. Males (n 55; age 34.1 (sd 8.9) years) with the metabolic syndrome were studied. Blood pressure, waist circumference, body weight, HDL-cholesterol (HDL-C), TAG, fasting plasma glucose (FPG), fasting blood insulin and insulin resistance indices (quantitati...

INTRODUCTION Information on insulin reference values and insulin sensitivity indices in the field of pediatrics is scarce. OBJECTIVE To describe insulin range and insulin sensitivity surrogate indices during childhood. MATERIALS AND METHODS Fasting insulin level range and surrogate indices, such as the homeostasis model assessment of insulin resistance (HOMA-IR), among healthy children and ...

This study aims to expand the evaluation of normal weight obesity (NWO) and its association with insulin resistance using an NHANES (1999-2006) sample of US adults. A cross-sectional study including 5983 men and women (50.8%) was conducted. Body fat percentage (BF%) was assessed using dual-energy X-ray absorptiometry. Expanded normal weight obesity (eNWO) categories, pairings of BMI and body fa...
