Birth chest circumference(CC) shows often, like birth gestational age(GA), tight direct relations to birth body weight(BW). However distinct connections of hypoxia/undernutrition with different body structures might be suspected based on brain-, heart- and adrenal-sparing following intrauterine growth restriction and, postnatally, on higher chest size for body mass observed at high altitude. Growth retarded fetuses gestated by hypoxic pregnant animals may present increments of...

Direct relationships of estimated birth brain weight(BRW) to birth body weight (BW) ratios (BBR) and of BW<=10.th centile for GA(SGA) with blood serum Insulin-like Growth Factor-II(IG2) to blood serum Insulin-like Growth Factor Binding Protein-3 (IB3) ratios (IG2/IB3R), and inverse relations between BW-SDS and birth chest circumference(CC) / BW ratio (i.e., CC through BW; CC/BWR) have been detected by our group in the human newborn(NWB). We evaluated the possibility that CC...

In the history of biosynthetic GH, first prediction models on long term outcome of therapy were based on large multinational cohorts of various growth disorders and have concentrated on GH dose. In this study we analyzed the 1st year and final height (FH) data in a large single center cohort (center of expertise for rare growth disorders) and compared patient outcome and predictions in GHD and SGA. Our aim was to predict treatment outcome using simple previously suggested para...

Background: Obese children with and without Type 2 diabetes have periodontal disease that relates to systemic inflammation. There is limited data on periodontal disease in children with Type 1 diabetes (T1D).Aim: We aimed to assess periodontal disease markers and its determinants in children and adolescents with T1D.Materials and Methods: Cross-sectional study including 73 children...

Background: Prader-Willi Syndrome (PWS) is a complex genetic disorder characterised by developmental and growth abnormalities, insatiable appetite, and excessive eating (hyperphagia). Hyperphagia is thought to be driven by supraphysiological levels of the appetite stimulating hormone ghrelin; however, the underlying causes of hyperghrelinaemia in PWS are currently unknown. Recently, ghrelin-reactive autoantibodies (isotype IgG) were identified in non-genetic obesity and were f...

Introduction: Anti-obesity drugs with increased efficacy and safety are urgently being sought. Peptide YY3–36 (PYY3–36) is an attractive drug target due to its anorectic effect and decreased circulation concentration, without drug resistance, in obese individuals. Its short half-life and required method of delivery are limiting factors in its clinical application. Transport and uptake mechanisms, including blood-brain barrier passage, of vitamin B12 (B12) is highly e...

Background: Pituitary stalk interruption syndrome (PSIS) is characterized by the absence of the pituitary stalk, pituitary hypoplasia and an ectopic posterior pituitary.Objective: We aimed to retrospectively analyze the clinical, auxological, biochemical, and radiological findings in Spanish patients with PSIS.Patients and results: Of 27 patients, 25% were female and 75% male. Perinatal features, auxological and endocrine study at ...

The increase in childhood obesity prevalence led to the establishment of a monographic obesity clinic since 2009 in our Department. To date, over 1600 patients have been visited, focusing on early onset severity and generating a valuable dataset on the characteristics of these patients (“The Madrid cohort”). This has allowed the performance of genomic and genetic studies, which have led to the demonstration of a genetic background, underlying the development of the d...

Background: While differences in gut microbiota between obese and lean subjects have been described, few studies have examined how adiposity across childhood relates to intestinal microbiota composition and diversity in late adolescence.Objective: To explore the correlations between measures of adiposity from childhood and adolescence with intestinal microbiota composition and diversity at 15–17 years.Methods: Data stem from t...

Background: Congenital hypothyroidism (CH) caused by DUOX2 deficiency has a wide range of clinical presentations and phenotype-genotype correlations are not always straightforward.Objective: To describe four children from Quebec with biallelic DUOX2 variants and widely variable phenotypes.Design/Methods: Case series of four children seen for evaluation of thyroid function at the endocrinology service of two university hospitals in ...
