Objectives: Modern treatments lead to increased survival rates from childhood cancer. Childhood cancer survivors (CCS) are a growing population group, which is at high risk for cardiometabolic disorders including metabolic syndrome, type 2 diabetes and cardiovascular disease. Obesity is one of the major drivers of these adverse outcomes, resulted from corticosteroids, radiotherapy, sedentary behavior, and precancer obesity. Assessment of obesity could identify...

Introduction: The good nutritional status of children in the first years of life is essential for their healthy growth and development. Evaluating the repercussions of nutritional status is fundamental since nutrition can influence both short-term and adult life.Objective: To analyze the temporal trends of the BMI of Brazilian children aged 0 to 5 between 2010 and 2022.Patients and methods:...

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Background: Anti-Müllerian hormone (AMH) is produced by granulosa cells in small follicles prior to gonadotropin dependent growth and serum levels reflect the number of small antral follicles. There are currently no longitudinal data of individual AMH levels from infancy to adolescence.Aim: To evaluate whether AMH in infancy and childhood is associated with AMH levels and ovarian morphology peripubertal and in adole...

In XLH, excess fibroblast growth factor 23 (FGF23) causes hypophosphatemia and consequent rickets, skeletal deformities, and growth impairment. The efficacy and safety of burosumab, a fully human monoclonal antibody against FGF23, was evaluated in two Phase 2 trials in children with XLH. In CL201, 52 children with XLH (5–12 years old, Tanner ≤2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) weeks, with doses titrated up to 2 mg/kg to...

Background: Growth during infancy is a continuation of the rapid fetal growth and its regulation is complex and multifactorial. It is well-established that insulin-like growth factor-I (IGF-I) and its regulators (e.g. IGF binding proteins (IGFBP-3) and pregnancy-associated plasma protein-A2 (PAPP-A2)) are important for prenatal and postnatal growth; however, their significance for growth during infancy is not fully explored.Aims: The aim...

Introduction: Mutations in hepatocyte nuclear factor 1Β (HNF1B) gene (chromosome 17q12), lead to monogenic diabetes (HNF1B-MODY or MODY5, OMIM 137920) accompanied by multisystem disorders. HNF1B gene encodes HNF1B protein, a member of the homeodomain-containing superfamily of transcription factors, expressed early in embryogenesis, contributing significantly to organogenesis and the function of many systems (kidneys, liver, panc...

Background: Obesity in childhood and adolescence represents a major health problem and is associated with significant morbidity and mortality in adult life. Osteopontin, NGAL and Sclerostin are bone biomarkers, however, little is known about their role in obesity.Objective and Hypothesis: The aim of our study was to determine the concentrations of Osteopontin, NGAL and Sclerostin in children and adolescents with overweig...

Background: The prevalence of obesity in childhood has increased dramatically during the last decades. Dyslipidemia, hypertension and insulin resistance – all components of the metabolic syndrome (MS) and well-known cardiometabolic risk factors – predispose to the development of inflammation and premature atherosclerotic cardiovascular disease in childhood.Aim: To determine “non- traditional” card...

Introduction: Germline mutations in Phosphatase and tensin homolog (PTEN) gene (chromosome 10q23) lead to PTEN Hamartoma Tumor Syndrome (PHTS), which includes Cowden syndrome. PTEN encodes a tumor suppressor protein that is a negative regulator of PI3K – Akt signaling pathway, taking part in multiple biological processes, including cellular cycle and regulation of metabolism.Materials and Methods:...
