Background and Objectives: Offspring born to obese mothers are at an increased risk of chronic disease including type 2 diabetes (T2D), obesity, hypertension, cardiovascular disease (CVD), non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD). This metabolic programming is produced, in part, by epigenetic changes such us DNA methylation. We postulated that obesity exposure impacts the offspring's methylome and used an epigenomic approa...

Carotid Intima-Media Thickness Relates Rather to Epicardial and Perirenal Fat than Total Body Adiposity in Apparently Healthy Children

Background: Carotid intima-media thickness (cIMT) is a well-known marker of subclinical atherosclerosis. The distribution of adipose tissue among visceral fat reservoirs rather than the total adipose tissue mass is more likely to be related to subclinical atherosclerosis.Objective: The aim of this study was to determine whether epicardial and perirenal fat are more related to cIMT than body adiposity in prepubertal child...

Leiva-Gea Isabel , Garcia Vázquez Javier , Rocío Liñán Jurado Francisca , Angel Maese Ruiz Miguel , Jiménez Hinojosa Jose , Pedro López-Siguero Juan

Flash glucose monitoring is now included in the Portfolio of Services of the Public Health System of Andalusia in Spain. We enrolled 145 paediatric T1D diabetes patients into a prospective, interventional study of the impact of the FreeStyle Libre system on HbA1c levels in this population, as well as additional measures of glycemic health, such as Time in Range (TIR) and Time Below Range (TBR). Subjects were trained in use of the FreeStyle Libre system at the start of the stud...

Objective: To evaluate the impact of gestational age and birthweight on dehydroepiandrosterone and dehydroepiandrosterone-sulfate (DHEA and DHEA-S) in children born very preterm (VPT) appropriate for gestational age (GA) compared to children born at term (T).Methods: We recorded anthropometric parameters in 72 VPT (<32 GA) and 41 T (≥ 38 GA) aged 5.0–8.5 years. Birthweight standard deviation scores (BW-SDS) were calculated using INTERGROWT...

Background: Body weight has a close correlation with bone mass in humans and high fracture rates has been reported in both obese and underweighted individuals. It is not clear the role of bone marrow adiposity (BMA) and the IGF system in this process.Aim: The aim of this study was to analyze bone composition and BMA in obese and non-obese children/adolescents and correlate them with the expression of the IGF type-1 receptor (IGF1R) in peripheral lymphocy...

Background: Hypothalamic obesity (HyOb) is a disease characterized by weight gain resistant to lifestyle changes and dietary restriction. The main clinical findings are hyperfagia and decline of satiety, high levels of insulin and an increase of adipogenesis. The major problem for these patients is that conventional treatments, either medical or surgical are not succesful and have variable results.Objective and hypotheses: We aim to describe the natural ...

Involvement of the Wnt/β-catenin Pathway, SF1, DAX1 and Stem/Progenitor Cell Markers in Paediatric Adrenocortical Tumors

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Soluble CD163, A Circulating Marker of Macrophage Activation, Associates With a Less Favourable Metabolic Profile in Children

Background: Soluble CD163 (sCD163) is shed from the cell surface into the circulation as a specific marker of macrophage activation. Macrophages are involved in low-grade inflammatory states such as obesity.Objective and hypotheses: To investigate the relationships between circulating sCD163 and metabolic parameters in asymptomatic prepubertal children.Method: A population of 236 school-aged Caucasian children (111 girls and 125 bo...

Background: Ovotesticular Disorder of Sex Development (OTDSD – true hermaphroditism) is rare, characterized by the presence of both presence of both testis and ovay tissue. Usually, these patients seek medical attention due to ambiguous genitalia.Case presentation: A 15-year-old boy, with ‘atypical’ genitalia and breast enlargement came for surgical correction. His genitalia had a more masculine aspect at birth and he had been submitted to...

Background and Aim: IRS1 (Insulin Receptor Substrate 1) is involved in the insulin signalling pathway and abnormalities thereof have been related to metabolic disorders and obesity. In obese subjects, insulin resistance has been associated with changes in IRS1 expression in peripheral in blood. Sex-based differences in cardiovascular disease are well established. Previous results from our group disclosed the association between IRS1 placental methylation with ...
