Background: Type 1 diabetes mellitus (T1DM) is one of the most frequent chronic diseases in the pediatric age and demands constant and rigorous glycemic control. Intermittently scanned continuous glucose monitoring (isCGM) systems are a helpful tool in diabetes management. Second-generation isCGM contain alarms to assist in the detection of hyper or hypoglycemia. We aimed to compare the sleep quality of principal caregivers of T1DM pediatric patients who use i...

Objective: Merge and standardize the scarce data on molecular and phenotypic findings of mutations in the human leptin receptor (LEPR) gene causing a rare form of severe early-onset obesity.Methods: We summarized functional and phenotypic traits of LEPR mutations reported in the literature in a structured and comprehensive manner. Additional data was obtained from 6 subjects of our outpatient clinic not reported so far. Functionality of mutations was ass...

Background: CREB-regulated transcription coactivator 3 (CRTC3) is found in adipocytes where it may promote obesity through disruption of catecholamine signaling. CRTC3 knockout mice are resistant to diet-induced obesity.Objective and Hypotheses: The goals of the present study were i) to assess whether CRTC3 is a soluble protein secreted by adipose tissue ii) to explore whether CRTC3 is detectable and quantifiable in the circulation, and iii) to ...

Background: In Brazil there is a nutritional transition between child malnutrition and increasing prevalence of obesity.Objective and hypotheses: The study aims to identify the prevalence of overweight and obesity in children aged 5–18 years in five private and 15 public schools from city of Uberaba Brazil.Method: Anthropometric data, inventorys physical activities and socioeconomic aspects were evaluated from 1125 individuals...

Introduction: Vitamin D (VitD) is a prohormone that is synthesized in the skin after sun exposure. Mandatory lockdown during the COVID-19 Pandemic may have altered the sun exposure time of children.Aim: to evaluate vitD levels in a sample of children and adolescents, and compare between pre-pandemic and pandemic periods.Methoths Children and adolescents, from a Portuguese tertiary ...

Background: Acute lymphoblastic leukemia (ALL) is the most frequently reported cancer in paediatrics. Reduced bone mineral density (BMD) and increased risk of fractures have been well-documented in this population, but long-term longitudinal trendlines of BMD and data about the impact of bone turnover markers are still scarce. Additionally, changes in body composition have to be furtherly analysed among childhood ALL survivors.St...

Background: MKRN3 (Makorin Ring Finger Protein 3) is a maternally imprinted intronless gene located in the Prader-Willi syndrome locus (chromosome 15q11.2-q13). It is recognized that MKRN3 loss-of-function mutations are the primary cause of familial central precocious puberty (CPP). The MKRN3 protein primarily acts as an E3 ubiquitin ligase, and its activity is essential for controlling the timing of puberty, functioning as a brake on gonadotropin-releasing ho...

Background and Aims: Turner Syndrome (TS), 45X0, is the most common chromosomal pathology affecting females, occurring in 1:2500 to 1:5000 female infants. The typical phenotype includes short stature, gonadal dysgenesis leading to sexual infantilism, low-set ears, low rear hairlin, mamary hypertelorism, neck webbing, gothic palate, irregular rotation of the elbows, shield chest, shortening of the 4th metacarpal, low hairline, shortening of lower extremities, renal disorders a...

Background: Severe congenital growth hormone deficiency (cGHD) is a rare but potentially life-threatening condition. Even though random growth hormone (GH) can confirm cGHD during the first week of life, the diagnosis remains extremely challenging in the absence of reliable reference values in healthy neonates and thus of a best diagnostic cut-off.Aims: First, to provide solid reference values for GH concentrations in te...

Background: Kinase suppressor of Ras 2 (KSR2) gene codes for a scaffold protein modulating intracellular pathways that involve MEK/BRAF cascade and AMPK signaling. KSR2 plays an important role in energy balance regulation, and KSR2 mutations were reported to be associated with obesity and insulin resistance in mice and humans. In transfected cells, several KSR2 mutations lead to impaired fatty acid oxidation, which improved under met...
