The gut microbiome has recently emerged as a major contributor to obesity and metabolic disease. Specifically, Bifidobacterium animalis sups. lactis (BAL) has shown promise for obesity treatment in human subjects, improving body composition and metabolic health. Moreover, tryptophan metabolism, a crucial regulator of satiety mechanisms and anxiety, is a main target of BAL. Given that clinical manifestations of Prader-Willi syndrome (PWS) include hyperphagia, ...

Background: Neurofibromatosis type 1 (NF1) caused by loss of function mutation in the NF1 gene; leads to the hyperactivation of RAS and its downstream mediators and contributes to tumour formation. The main manifestations of NF1 are café au lait macule, axillary and/or inguinal freckling. Neurofibroma plexiform is specific for NF1 and identified on the face and trunk. Urogenital presentation is infrequent in the penis. Identification of this lesion is essential because it...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...

Background and Aim: Gliomas are the most frequent solid tumors in pediatric population. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. In a previous work we have reported the quantitation of some components of the IGFs system in SNC pediatric tumours (IGF-1, IGF-2, IGF-1R, IR), being IGF-2 expression the most variable among all the genes studied.Our aim w...

Objectives: The etiopathogenetic of childhood obesity is related to genetic and environmental factors: not only caloric intake or physical activity have an important influence, but also circadian rhythms, including healthy sleep.The objectives of this study were: a) to analyze the different patterns and duration of sleep, eating habits, meal schedules, time dedicated to exercise and screens of obesity children; b) to evaluate its possibl...

Introduction: Preclinical models demonstrated that Angiopoietin-like protein 4 (ANGPTL-4) regulates lipid metabolism and affects energy homeostasis. However, no data exist regarding its involvement in childhood and adolescence, periods of life with important metabolic changes.Objectives: We aimed to investigate circulating levels of ANGPTL-4 in children and adolescents and its relationship with gender, puberty and obesit...
