Background: The peptides obestatin and adropin are thought to regulate glucose and lipid metabolism, weight gain, and fluid intake in adults. The roles of obestatin and adropin in the regulation of weight and glucose and lipid metabolism in Prader-Willi syndrome (PWS) and non-syndromic pediatric obesity are poorly understood. This study compares the concentrations of obestatin and adropin in infants and children with PWS and age- and BMI-z matched controls, and explores the as...

Background: Insulin/IGF1 signaling plays a critical role in central glucose bioavailability and lipid metabolism. An increase in glucose disposal can generate reducing agents through the pentose-phosphate pathway necessary for the synthesis of free fatty acids (FFA). Disturbances in lipid synthesis are related to the appearance of insulin resistance and diabetes. The insulin receptor substrate 2 (IRS2) deficient mice (IRS2−/−) is an excellent model to st...

Introduction: Congenital nasal pyriform aperture stenosis (CNPAS) is an increasingly recognised cause of upper airway obstruction associated with holoprosencephaly, of which solitary median maxillary central incisor (SMMCI) is the least severe form. Studies have described pituitary abnormalities in up to 40%. We aimed to determine the use of baseline endocrine investigations and MRI brain in assessing endocrine dysfunction.Method: Retrospective casenote ...

Background: Neonatal diabetes (NDM) is defined as diabetes developing before 6 months of age, affecting one in 100 000 live births. Permanent NDM is diagnosed in the first 6 months of life with no remission. The majority have a mutation in the ATP-sensitive potassium (KATP) channel (KCNJ11 in 31%, ABCC8 in 13%). Autosomal dominant and recessive forms are described. The majority of patients with NDM caused by KATP mutations respond to sulphonylureas.<p...

Background: Exposure to non-persistent pesticides may have an effect on prenatal growth and later risk of adiposity. Prenatal pesticide exposure has been found to be associated with lower birth weight and higher body fat percentage calculated from skinfolds at age 6–11 years. Body composition measured by using DXA in children prenatally exposed to pesticides has not previously been reported.Objective and hypotheses: To study the effects of prenatal ...

Background: AHDS is a devastating disease caused by defects in the thyroid hormone (TH) transporter MCT8. Endocrine expression is heralded by systemic hyperthyroidism with elevated serum T3, mildly increased TSH and decreased T4. However, the brain is hypothyroid, causing severe psychomotor retardation. Therapeutic attempts with PTU+levothyroxine or the T3-analogue DITPA could normalize TH derangements but without any neurological improvement. ...

Background: Homozygous aggrecan (ACAN) mutations have been described in a few skeletal dysplasias whilst more recently, heterozygous ACAN mutations have been reported in few families presenting with idiopathic short stature with advanced bone maturation and premature growth cessation.Case presentation: We describe two novel heterozygous ACAN stop mutations, detected using a skeletal dysplasia NGS panel and confirmed by Sanger sequencing...

Introduction: The Body Mass Index (BMI) is an essential indicator for the nutritional assessment of children and reflects the exposure to health conditions that are harmful to the development of this population.Objective: To analyze the temporal trends of the BMI of Brazilian children aged 5-10 between 2010 and 2022.Patients and methods: Descriptive ecological study. Data obtained ...

Introduction: Adequate nutritional status of adolescents is essential for their healthy development, with health repercussions in both short-term and adult life.Objective: To analyze the temporal trends of the BMI of Brazilian adolescents (10 to 19 years old) between 2010 and 2022.Patients and methods: Descriptive ecological study. Data obtained from e-SUS Primary Care. The BMI cat...

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:...
