Brown Adipose Tissue in Prepubertal Children: Associations with Sex and With the Sequence of Prenatal Growth Restraint and Postnatal Catch-up

Malpique Rita , Gallego-Escuredo Jose Miguel , Sebastiani Giorgia , Villarroya Joan , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

Background/objectives: Individuals born small-for-gestational age (SGA), especially those who experience postnatal catch-up growth, are at increased risk for developing endocrine-metabolic abnormalities before puberty. In adults, brown adipose tissue (BAT) has been associated with protection against metabolic disorders, such as obesity, type 2 diabetes and dyslipidaemia. Here, we assessed for the first time whether BAT activation differs between prepubertal children born SGA o...

Cardiac and Vascular Assessments in Small- vs Appropriate-for-Gestational-Age Infants at Ages 1 and 2 Years

Garcia-Beltran Cristina , Sebastiani Giorgia , Pie Stella , Guerra Alberto , Lopez-Bermejo Abel , de Zegher Francis , Roses Ferran , Ibanez Lourdes

Background: Children born small-for-gestational age (SGA), especially those who experience spontaneous postnatal catch-up growth, are at increased risk for developing insulin resistance, central adiposity and cardiovascular abnormalities later in life. By age 3-6 years, SGA children have a broader aortic and carotid intima media thickness (aIMT and cIMT) which are markers of preclinical atherosclerosis.Objective: To assess longitudinally – at age 12...

Genetic Study of Osteogenesis Imperfecta: Two Novel Mutations in COL1A1 and COL1A2

Castro-Feijoo Lidia , Loidi Lourdes , Quiroga Nuria , Cabanas Paloma , Heredia Claudia , Leis Rosaura , Barros Francisco , Pombo Manuel , Barreiro Jesus

Background: Osteogenesis imperfecta (OI) is a clinically and genetically heterogeneous rare disorder characterized by variable symptoms including predisposition to fractures. OI has been associated with mutations affecting the synthesis of type I collagen. However, the new technologies have permitted the identification of other responsible genes which are in the collagen metabolic pathway, while others are not.Objective: Characterize the genotype of pati...

Mitochondrial DNA in Placenta: Associations with Fetal Growth and Superoxide Dismutase Activity

Diaz Marta , Aragones Gemma , Sanchez-Infantes David , Bassols Judit , De Zegher Francis , Lopez-Bermejo Abel , Ibanez Lourdes

Background: Prenatal growth restraint associates with increased oxidative stress – as judged by mitochondrial dysfunction – in pregnancies complicated by preeclampsia or diabetes, but it is uncertain whether this is also the case in uncomplicated pregnancies.Objective and hypotheses: To assess the link between fetal growth restraint and placental mitochondrial dysfunction, as reflected by changes in mitochondrial DNA content and superoxide dism...

From the Need of Preventing Infantile Obesity as soon as Possible: a New Score at Birth

Sanz Nuria , Asencio M Jesus , Buj Angeles , Marzo Corpus , Rodriguez Juan Manuel , Sanchez Consol , Ibanez Lourdes , Marcos Maria Victoria

Background: Infantile obesity is nowadays a pandemic disease and needs a paediatrician interventional attitude. Since 1990 until 2010 it has trebled and the World Health Organization recommends prevention ‘as soon as possible’ even during the first year of life. A Spanish study (Aladino 2011) stimated the prevalence of overweight in boys as a 26.3% and in girls a 25.9% and the prevalence of obesity as a 22% and a 16.2% respectively. Our aim was to set up a new score ...

Circulating Progranulin in Human Infants: Relation to Prenatal Growth and Early Postnatal Nutrition

Díaz Marta , Mestres-Arenas Alberto , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Progranulin (PGRN) displays pleiotropic biological functions including on early embryogenesis, cell proliferation, lysosomal or neuronal functioning and wound repair, and has been proposed as a biomarker for metabolic diseases. Increased PGRN levels have been reported in type 2 diabetes, nonalcoholic fatty liver disease and in preeclampsia associated to placental dysfunction. However, the ontogeny of PGRN concentrations and the potential value of P...

Increased Basal Levels of 17-Hydroxyprogesterone In The Covid ERA: Must We Change The Cut-Off Point To Request Acth Test?

Laura Bertholt Zuber M. , Alonso Rubio Pablo , Palenzuela Revuelta Inmaculada , Pozas Mariscal Sara , Lavín Gómez Bernardo , Teresa Garcia Unzueta M.

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Germline and Somatic DICER1 Mutations in Familial Papillary Thyroid Carcinoma and Multinodular Goiter

Lumbreras Cesar , Chueca Maria Jesus , Arribas Laura , de Randamie Rajdee , Alonso Angel , Fernandez Pilar , Berrade Sara , Anda Emma , Regojo Rita Maria , Mendiola Marta , Moreno Jose Carlos

Background: The inheritable component of familial Papillary Thyroid Cancer (fPTC) was recently attributed to monogenic defects in a reduced number of genes including DICER1. DICER1 codes for a ribonuclease of the RNaseIII family essential for the biogenesis of microRNAs.Objective and hypotheses: We aimed to identify germline and/or somatic mutations in DICER1 in a familial pedigree with PTC, multinodular goiter (MNG) and other ...

Implications of parental anxiety, and fear of Hypoglycemia in glucose control of their Children with Type 1 Diabetes

Dominguez-Riscart Jesus , Garcia-Zarzuela AAna , Buero-Fernandez Nuria , Martin-Bravo Enrique , Ruiz-Ocaña Pablo , M Lechuga-Sancho Alfonso

Introduction: Hypoglycemia is the most common acute complication in T1D. It has ominous symptoms and it is potentially fatal. Parents of infants with T1D are instructed in how to avoid, detect and manage these episodes. However, it is well known that many parents develop fear of hypoglycemia (FoH) which may lead to phobic avoidance behaviors such as permanent hyperglycemia and anxiety, losing optimal metabolic control. We aimed to explore how parenting stress ...
