Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...

Entry: Rickets is a generalized metabolic bone disease manifested by the abnormal increase in osteoid tissue, defective mineralization and deformation of the epiphyseal plate, which occurs as a result of vitamin D and mineral deficiency before epiphysial fusion occurs in adolescence. Although rickets is mostly seen due to vitamin D deficiency, it can rarely be seen in vitamin D metabolism disorders and diseases that cause phosphorus loss. Clinical findings suc...

Obesity presents a major worldwide challenge, due to its numerous, severe adverse effects on health. This leads to a necessity to further investigate the mechanisms underlying lipid accumulation. The adipocytokine leptin may contribute to this process. While there already has been thorough research into central leptin action, deepening our understanding of leptin’s effects on whole-body energy homeostasis, relatively little is known about its auto- and paracrine effects....

Background: Childhood brain tumour survivors are at risk of developing endocrine secondary effects throughout lifetime. Transition between childhood and adult care is a critical moment during which patients may stop medical visits and treatments.Objective: To describe endocrine care transition in our cohort of patients with primary brain tumors followed from 2010-2015, who are ≥=18 years old by December 31st</...

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

Background: The fluid milieu along the female reproductive tract has a major role in a complex series of events that follow oocyte ovulation. These include oocyte transport in the fallopian tube, the transport and capacitation of sperm, fertilization, transport of the blastocyst and implantation of the embryo in the uterus. These processes are regulated by the activity of ion channels located on the surface of endometrial epithelia. In our previous studies we showed that epith...

Introduction: Leptin, an adipokine secreted mainly by adipose tissue, is a regulator of energy balance acting through central mechanisms on the hypothalamus. However, leptin has many functions regulating e.g., immune system and reproduction. Leptin exerts its biological effects through its receptor, the expression of which has been demonstrated in several tissues. There are several leptin receptor isoforms, but activation of only one of them, the long form, re...

Background: N-acetylneuraminic acid synthetase-congenital disorder of glycosylation (NANS-CDG) is a recently established rare autosomal recessive disease caused by pathogenic variants in NANS involved in the biosynthesis of N-acetylneuraminic acid (the most common member of sialic acids). Sialic acids are ubiquitously distributed in the body including the brain and skeletal system, and are required for the development and function of multiple organs/tissues. C...

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...

BMP4, a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily, is involved in the embryonic development of various organ and tissues including the cranio-facial structures, olfactory placode, pituitary, eyes, heart, and kidneys. Mutations in this gene are associated with orofacial cleft and microphthalmia in human patients. BMP4 plays an important role in the embryonic development of the GnRH neurons ...
