C Mendes Ariana , Pereira Janet , Mirante Alice , M Saraiva Jorge , R. Soares Ana , B. Sousa Sérgio , Rosmaninho-Salgado Joana

Background: Melanocortin 4 receptor (MC4R) deficiency is the commonest monogenic form of non-syndromic obesity. MC4R is a seven transmembrane G-protein coupled receptor implicated in central regulation of body weight. The loss-of-function mutations in MC4R gene will contribute to early-onset obesity associated with hyperinsulinemia, hyperphagia and “binge eating”. We aim to determine the prevalence of MC4R variants in a Pediatrics...

Evaluation of the Frequency and Time Course of Side Effects Asscociated With Metformin Use In Obese Adolescents As Related to Weight Loss: A Prospective Single-Centre Observational Study

Mısırlı Özdemir Ebru , Dağdeviren Çakır Aydilek , Bilge Özakçe Mehmet , Uçar Ahmet

Background: Metformin is a well-known biguanide approved for treatment of Type2 Diabetes. Metformin is not considered as an anti-obesity drug despite its common off-label use. Currently, there are no data regarding the profile of metformin related gastrointestinal side effects (MRGSE) in obese adolescents.Aim: To identify the frequency and time course of MRGSE in obese adolescents and assess the presence of any associati...

A myostatin inhibitory antibody potentiates the positive effects of insulin on the skeletal muscle and bone phenotype of insulin-deficient diabetic female mice

Kalaitzoglou Evangelia , Adatorwovor Reuben , Ray Philip , Keeble Alexander , Fry Christopher , Uppuganti Sasidhar , Nyman Jeffry , Fowlkes John , Clay Bunn R

Background: Type 1 diabetes is associated with deficits in skeletal muscle and bone mass and quality. Inhibition of myostatin, a negative regulator of muscle mass, was explored as a therapeutic modality to improve the muscle and bone phenotype associated with insulin-deficient diabetes.Methods: We investigated whether an inhibitory myostatin antibody in streptozotocin (STZ)-induced diabetes in female mice is protective f...

Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...

Background: Protein subfamilies within the Nuclear receptor (NR) family share common domain architecture. These closely related receptors and their cognate ligand compounds play a key role in homeostasis, reproduction, growth, and development. Despite their biological significance, their evolution and diversification remains to be elucidated. SNPs and mutations are characterized by the permanent alteration of the nucleotide sequence in the genome of an organism. These alterati...

Short-term impact of therapy with GNRH analogues on the growth of female children with central precocious puberty: a retrospective study of the last 20 years

Luísa de Carvalho Ana , Carvalho Adriana , Martins Sofia , Antunes Ana , Miguel Gomes Maria

Introduction: Since the 1980s, long-acting gonadotropin-releasing hormone analogues (GnRHa) have been the standard treatment for central precocious puberty (CPP).Aims: To evaluate the short-term response (at 6 and 12 months) of treatment with GnRHa in female children diagnosed with CPP, regarding growth, bone maturation (Greulich and Pyle method), predicted adult height (PAH) and pubertal development (Tanner stages)....

Gamma-Glutamyl Transferase (GGT) and The GGT / High-Density Lipoprotein (HDL) Ratio: Useful Tools for Identification of OBESE Children with Insulin Resistance

Nuzio Salvatore Guercio , Livio D'Isanto

Introduction: The role of gamma-glutamyl transferase (GGT) enzyme as a marker of insulin resistance (IR) in pediatric obesity is well known. Recent evidence, mainly in the adult population, has identified GGT/High-Density Lipoprotein (HDL) ratio as a risk index for hepatic steatosis. The study has the purpose of examining the relationship between GGT, GGT/HDL ratio and the clinical/laboratory data of a group of obese Italian children living in the province of ...

Introduction: Body mass index (BMI) and waist circumference (WC) are the main anthropometric measures of obesity. However, their inability to take into account body fat distribution raises queries for their predictive value of insulin resistance (IR) in youth.Aim: The aim of this study is to compare BMI and WC with latest anthropometric indices in the assessment of IR in a paediatric Greek population with overweight and ...

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...
