Circulating Concentrations of Fibroblast Growth Factor 21 are Undetectable in Human Infants at Term Birth and Surge within Hours After Birth

Sanchez-Infantes David , Gallego-Escudero Jose Miguel , Cereijo Ruben , Diaz Marta , Aragones Gemma , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

Background: In rodents, fibroblast growth factor 21 (FGF21), an endocrine member of the FGF family, is mainly produced in the liver and promotes glucose oxidation in several tissues; the circulating concentrations of FGF21 rise shortly after birth. In the human, the ontogeny of circulating FGF21 is essentially unknown.Objective and hypotheses: To assess whether there is also a neonatal surge of circulating FGF21 concen...

Bassols Judit , Soriano-Rodriguez Pilar , Prats-Puig Anna , Carreras-Badosa Gemma , Miranda-Arce Miguel-Angel , Alvarez-Castano Elena , de Zegher Francis , Ibanez Lourdes , Lopez-Bermejo Abel

Background: Sex hormone-binding globulin (SHBG) is the major sex steroid carrier protein. Its production is negatively regulated by insulin and monosaccharides. The concentration of SHBG increases between 16 and 27 weeks gestation and is negatively associated with pre-gestational BMI and weight gain during pregnancy. The link of SHBG with cardiovascular risk is poorly understood.Objective and hypotheses: In obese pregnant women, we aimed to study the ass...

Type 1 Diabetes Onset: A Story of Innate and Adaptive Immune Cells?

Fitas Ana Laura , Martins Catarina , Alonso Anabela , Nunes Gloria , Pina Rosa , Amaral Daniela , Lenzen Sigurd , Lopes Lurdes , Borrego Luis Miguel , Limbert Catarina

Background: Type 1 diabetes (T1D) is a T cell-mediated autoimmune disease. A more complex immunological picture is being unraveled, with a key role of innate immune cells at disease onset and maintenance. For new therapies based on immune-modulation to be possible, immune characterization of T1D patients is crucial.Objective and hypotheses: We aimed to characterise innate and adaptive immune cells of T1D children at a well-defined ‘onset-window&#146...

Sex Differences in the Pubertal Response to High-Fat Diet

Freire-Regatillo Alejandra , Argente-ARizon Pilar , Diaz Francisca , Barrios Vicente , Arevalo Angeles , Argente Jesus , Garcia-Segura Luis Miguel , Azcoitia Inigo , Chowen Julie A

Background: It is well known that ingestion of a high fat diet (HFD) can induce rapid weight gain and metabolic imbalances. However, males and females are not equally susceptible to these effects. Furthermore, an individual may be more prone to gain weight during specific developmental periods.Aims and objectives: We aimed to analyse the response to the acute exposure to a HFD during pubertal/adolescent period and to determine whether males and females r...

A rare presentation of Dysplasia Epiphysealis Hemimelica combined with Familial Hypocalciuric Hypercalcemia – Is this association possible?

Toledo Arthur H. T. , Diesendruck Benjamin , Rodrigues Marcela , Baches Jorge Rafael , Akkari Miguel , Santili Claudio , Baratela Wagner A. R. , Goiano Ellen de Oliveira , Malaquias Alexsandra C. ,

Background: Familial Hypocalciuric Hypercalcemia (FHH) type 1 is a benign condition of hypercalcemia with autosomal dominant inheritance caused by pathogenic variants in the calcium-sensing receptor gene (CASR). CaSR plays a crucial role in the regulation of calcium balance. Inactivating mutations in CASR result in altered calcium-sensing and inappropriate parathyroid hormone (PTH) release concerning the calcium concentration. Dysplasia Epiph...

Self-perception of voice in trans girls adolescents depends on pubertal stage blockage.

Domínguez-Riscart Jesus , Larran-Escandon Laura , Baez-Castillo Celia , Triviño-Garcia Adrian , Mateo-Gavira Isabel , De Mier-Morales Miguel

Introduction: A transgender individual’s voice may contribute to the negative psychosocial outcomes. Some studies have shown that an incongruence between one’s voice and internal gender identity can be a potential source of ongoing psychological distress and could impact on their social interactions, employment outcomes, and invite verbal or physical harassment. This study was aimed to examine whether early puberal blockage (PB) impacts on self per...

Development and validation of simultaneous quantification of urinary catecholamines and free metanephrines by UHPLC-MS/MS method

Eugenia Rodriguez Maria , Gabriela Ballerini Maria , Ambao Veronica , Vieites Ana , Sanso Gabriela , Rey Rodolfo , Bergada Ignacio , Gabriela Ropelato Maria

Background: Neuroendocrine tumors from adrenal and extra-adrenal chromaffin cells are characterized by overproduction of catecholamines (CA), leading to the increase of urinary O-methylated metabolites (uO-Met) excretion, reliable biomarkers for the initial screening, diagnosis and monitoring of patients with pheochromocytoma and paragangliomas (PPGLs).Objective: To develop and validate a UHPLC-MS/MS method for the simul...

Serum IGFBP-2 Concentration in Neonates with Potential Diagnosis of Growth Hormone Deficiency (GHD)

Gabriela Ballerini Maria , Braslavsky Debora , Keselman Ana , Eugenia Rodriguez Maria , Gotta Gabriela , Gabriela Ropelato Maria , Bergada Ignacio

In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

Insulin Sensitivity in Girls with Central Precocious Puberty at Diagnosis and at 6 Months of GnRH Analogue Treatment

Arcari Andrea , Freire Analia , Escobar Maria Eugenia , Ballerini Maria Gabriela , Ropelato Maria Gabriela , Bergada Ignacio , Gryngarten Mirta

Background: Puberty is associated with a physiological decline in insulin sensitivity. Overweight and obesity are common among girls with Central Precocious Puberty (CPP). CPP and early menarche have been considered as risk factors for obesity and cardiovascular diseases during adulthood. Besides, concern has been raised by the potential impact of GnRH analogues (GnRH-a) treatment on body weight and metabolic profile.Objective and hypotheses: To evaluate...
