Introduction:The incidence of obesity increases unstoppably in all populations and at all ages, and with it, the associated metabolic morbidity and mortality. The promotion of physical activity and a healthy diet are the fundamental elements to alleviate this situation. The objective of this study is to determine the relationship of physical activity and eating patterns with body composition, the degree of adiposity and certain metabolic risk factors.<p cl...

Background: Autoimmune diseases (AIDs) have familial aggregation and frequently share a common genetic background, but few studies have evaluated autoimmune clusters in children with AIDs and their families.Objective and hypotheses: To identify clusters of AIDs in children and their first-degree relatives.Method: A cross-sectional study was performed in subjects with an AID of pediatric onset (<18 years) recruited at Pediatric ...

Background: The SRY protein is a transcription factor that contains a high mobility group (HMG) homeobox domain which possesses sequence-specific DNA binding activity and regulates other genes involved in male sex determination pathway. The majority of the identified mutations occurred within the HMG-box motif. There are few reports of pedigrees with familial transmission.Objective and Hypotheses: To describe a paternally transmitted novel SRY mutation w...

Background: Obesity rates in children and adolescents have increased dramatically across the globe, and the lifelong impact of obesity is more severe when onset begins at ≤20 years of age. However, the experiences, challenges and needs of adolescents living with obesity (ALwO), their caregivers, and the healthcare providers (HCPs) who treat them are poorly understood. ACTION Teens, the first study of its kind, aims to improve the lives of ALwO by generat...

Introduction: An increase in liver enzymes predicts cardiac hypertrophy secondary to increased left ventricular mass in patients with cardiovascular disease. The mechanisms involved include decreased adiponectin concentration and increased epicardial fat in these subjects. We hypothesized that associations between these parameters would also be readily apparent in otherwise healthy children.Objectives: Our objective was ...

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

Introduction: Thyroid hormones regulate body composition and metabolism, and are among the key drivers of body growth and maturation. In children, associations of cardio-metabolic measures with the circulating prohormone thyroxine (T4) have been extensively studied, but not with active triiodothyronine (T3). In apparently healthy children, we studied whether circulating free T3 (fT3) [and its ratio with free T4 (fT3/fT4)] associates with cardio-metabolic measu...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

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...

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...
