Insulin Clearance at the Pubertal Transition in Youth with Obesity and Steatosis Liver Disease.

No data are available on insulin clearance (Cl) trends during the pubertal transition. The aim of this study was to investigate in 973 youths with obesity whether Cl in fasting and post-oral glucose challenge (OGTT) conditions varies at the pubertal transition in relation to the severity of obesity and the presence of steatosis liver disease (SLD). The severity of obesity was graded according to the Centers for Disease Control.

High 1-h glucose in youths with obesity as marker of prediabetes and cardiovascular risk.

Purpose: Testing 1-h glucose (1HG) concentration during oral glucose tolerance test is cost-effective to identify individuals at risk of incident type 2 diabetes. Aim of the study was to define 1HG cutoffs diagnostic of incident impaired glucose tolerance (IGT) in youths with obesity, and to evaluate prevalence and association of cutoffs identified in the cohort and from the literature (133 and 155 mg/dl) to cardiovascular disease (CVD) in a population of youths with obesity.

Methods: This is a longitudinal study of 154 youths to identify 1HG cutoffs, and cross-sectional study of 2295 youths to estimate prevalence of high 1HG and association to CVD.

The Effects of Nutrition on Linear Growth.

Linear growth is a complex process and is considered one of the best indicators of children's well-being and health. Genetics, epigenetics and environment (mainly stress and availability of nutrients) are the main regulators of growth. Nutrition exerts its effects on growth throughout the course of life with different, not completely understood mechanisms.

Long-Acting Growth Hormone Preparations and Their Use in Children with Growth Hormone Deficiency.

Background: Daily recombinant human growth hormone (rhGH) is approved and marketed worldwide to treat children and adults with GH deficiency and other conditions. Efficacy of rhGH therapy is influenced by several variables. Drop of treatment adherence over time has been recognized as a cause of reduced rhGH efficacy and has driven considerable efforts from pharmaceutical companies and scientists to develop long-acting rhGH (LAGH) formulations in order to relieve patients and their families from the burden of daily injections.
