Mandatory lockdown during COVID 19 pandemic obstaculized access to medical attention. Newborn screening (NBS) for congenital hypothyroidism (CH) in Buenos Aires province has been obligatory since 1995 and performed sustainedly. CH causes mental delay if not diagnosed and treated early.Objectives: The aim of this study was to determine if mandatory lockdown changed time of established NBS diagnosis steps.Mat...

Background: It has been shown that a proportion of relatives with multiple islet auto antibodies do not develop diabetes for many years, indicating that a more accurate marker of advanced insulitis is needed.Objective and Hypotheses: We evaluated whether the level of HbA1c can discriminate children at risk of T1D onset in a cohort of auto antibody positive relatives.Method: A total of 74 subjects <18 years of age who were parti...

Introduction: Pubertal growth is hormone dependent. The anthropometric (height, weight) and sexual (Tanner stage (TS)) changes are accompanied by growth in foot length. However, the relationship between changes in foot length and other anthropometry remains unclear. Our aim was to determine how changes in foot length relate to growth parameters (height and weight), self-rated TS and serum sex steroids.Methods: We used data from the Adolescent Rural Cohor...

Background: The hepatokine FGF21 signals through a dual receptor complex consisting of FGFR1c and the obligatory co-receptor β-Klotho to regulate glucose and lipid metabolism. Interestingly, female mice with Fgf21 transgenic overexpression are not only resistant to high-fat diet induced obesity but also present with hypogonadotropic hypogonadism (HH) and infertility. Loss-of-function (LOF) mutations in FGFR1 are a frequent cause of congenital HH (CHH). W...

Background: Main features of the autosomal dominant form of GH deficiency (IGHD II) include markedly reduced secretion of GH combined with low concentrations of IGF-I leading to short stature.Objective and hypotheses: We report on a girl referred for assessment of short stature (−4.6 SDS) at a chronological age of 7 yr 10 mo. The GH deficiency was confirmed by standard GH provocation tests, which revealed severely reduced GH and IGF-I concentration...

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

Background: Fetuin-A plays a role in insulin resistance and cardiovascular disease.Objective and hypotheses: The aim of present study was to determine the relation between fetuin-A levels and caridiometabolic risk factors and to investigate effect of serum fetuin-A to insulin sensitivity indices for determining whether fetuin-A is additional marker of insulin resistance in prepubertal children.Method: Ninety-nine prepubertal Korean...

Background: Turner syndrome (TS) patients typically exhibit short stature and gonadal dysgenesis with pubertal delay and infertility. Up to 30% of these girls will have spontaneous pubertal development, however only 2% achieve a spontaneous pregnancy. Biochemical markers reflecting the ovarian reserve in girls and adolescents with TS are therefore needed.Objective and hypotheses: Evaluation of the ovarian reserve in girls and adolescents with TS using se...

Background: Recent studies have shown a rising trend in pediatric obesity. However, studies dealing with the ultimate metabolic consequences of pediatric obesity and the means of accurately predicting these consequences are limited.Objective and hypotheses: To study the utility of WHtR as a marker of insulin resistance. To validate the presently used cutoffs (≧0.5) and validate its utility in populations studies.Method: 96 c...

Background: Obesity is considered to be a chronic inflammatory state in which the dysfunction of adipose tissue plays a central role. Adipose tissue is known to express and secrete a variety of products known as ‘adipokines’ including leptin, adiponectin, resistin, and visfatin, as well as cytokines and chemokines such as tumor necrosis factor-α (TNF-α), interleukin-6, and monocyte chemoattractant protein-1.Objective and hypotheses: T...
