Background: Gonadal function is altered up to 25% in patients who suffered cancer in childhood. Cryopreservation of ovarian tissue (COT) is an option for preserving fertility.Aims and objective: To establish the prevalence of primary hypogonadism (PH) in children with cancer after hematopoietic cell transplantation (HCT). To analyse the variables that predict progression to PH.Methods: Retrospective cohort study. Patients aged 0 to...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Background and Aims: Long chain polyunsaturated fatty acids (LC-PUFA) are essential nutrients for the development of the fetus and are supplied by the mother through the placenta. Omega-6 arachidonic acid (AA) and both omega-3 eicosapentaenoic acid (EPA) and docoshexaenoic acid (DHA) stand out for their functional roles. Recent studies show that the concentrations of these fatty acids in maternal blood and umbilical cord are associated with adiposity in the of...

Background: Use of recombinant human growth hormone (somatropin) is recommended for children with growth hormone deficiency (GHD) to normalize adult height and avoid extreme short stature. Prior research conducted among small study samples, across different study populations and health care systems, has suggested an association between adherence to somatropin and clinical outcomes, including height velocity. There is a need for further research, using real-wor...

Introduction: Obesity and the metabolic syndrome (MetS) are linked to increased risk for endothelial dysfunction which is considered as the first step in the progression of cardiovascular disease. Fibroblast growth factor 21 (FGF21) is a protein with known effects on various metabolic pathways. In adults, the circulating blood levels of FGF21 have been associated with parameters of lipid/carbohydrate metabolism, and FGF21 is known to be increased in obesity. T...

Background: Sclerostin is an inhibitor of the Wnt/b-catenin bone metabolic pathway. Increased sclerostin levels and reduced bone mineral density (BMD) have been documented in adult patients with diabetes mellitus (DM), predominantly in those with T2DM. No relevant data exist on childhood T1DM.Objective and hypotheses: Our aim was to study plasma sclerostin concentration in children and adolescents with T1DM and controls and to correlate sclerostin levels...

Background: Several bone metabolic pathways seem to be disrupted in patients with type 1 diabetes mellitus (T1DM), leading to reduced bone mass.Objective and hypotheses: Our aim was to study bone metabolism markers in children and adolescents with T1DM and their correlation with bone mineral density (BMD).Method: We evaluated 40 patients (mean±S.D. age 13.04±3.53 years, mean±S.D. T1DM du...

Background: Disruption of many bone metabolic pathways and reduced bone mass are associated with diabetes mellitus. Increased fracture risk and elevated Dickkopf-1 and sclerostin levels, which are inhibitors of Wnt/β-catenin pathway, have been found in adult T2DM patients, but no relevant data exist on childhood T1DM.Objective and hypotheses: We aimed at studying plasma Dickkopf-1 and sclerostin concentration in children and adolescents with T1DM an...

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

Background: Obesity in childhood and adolescence represents a major health problem of our century. In Greece, more than 30-35% of children and adolescents are currently overweight or obese.Objective: To evaluate and further develop the 'National Registry for the Prevention and Management of Overweight and Obesity in Childhood and Adolescence' in order to provide personalized intervention programs for overweig...
