Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Introduction: The human adrenal gland originates from the adrenogonadal primordium at around 4 weeks post conception (wpc) and undergoes marked developmental changes throughout the first half of pregnancy. Several key aspects of adrenal maturation are well-established, such as the formation of a large inner fetal zone (FZ) and synthesis of dehydroepiandrosterone, but many other processes contributing to adrenal gland development and function in humans are stil...

Introduction: Ovary development was once considered a largely passive process. RNA sequencing (RNAseq) approaches have allowed us to begin to characterise ovary development in previously unparalleled detail, revealing the process to be complex and, still, little understood. A challenge is synthesising and using these data to advance our understanding of clinical disease. Through a clinically-focused lens, we elucidate novel aspects of the transcriptional lands...

The Growzen™ buddy smartphone application shows positive findings on adherence in Argentinian patients receiving growth hormone therapy for growth disorders

van Dommelen Paula , Arnaud Lilian , Assefi Aria , Lourdes Crespo Maria , Koledova Ekaterina

Background: Digital health solutions, such as the Growzen™ buddy smartphone application (app), can facilitate adherence to recombinant human growth hormone (r-hGH) treatment for patients with growth disorders. The app alerts patients when it’s time for an injection and allows patients and their caregivers to self-monitor growth, to build a routine and improve adherence. The app also contains educational resources to empower patients to be active in...

Evaluation of trends and care of transgender young assisted in a reference unit.

Dominguez-Riscart Jesus , Crespo-Delgado Angela , Mateo-Gavira Isabel , Baez-Castillo Celia , Larran-Escando Laura

Introduction: Transgender people and the gender transition process requires a series of processes with psychosocial, legal and physical implications. In our community, with the establishment of the care plan for trans youth, reference units were created in 2015. We had an interest to analyze the different epidemiological variables and the type of care demand of this population cared for in our unit.Methodology: An observ...

The bilirubin/triglycerides Ratio Predicts Changes over time in Glycated Hemoglobin in Prepubertal Healthy Children

Puerto-Carranza Elsa , Nuevo Casals Silvia , Roca Portella Berta , Xargay-Torrent Silvia , Lizarraga-Mollinedo Esther , Mas-Pares Berta , deZegher Francis , Ibañez Lourdes , Bassols Judit , Bermejo Abel López

Background: Low serum bilirubin and high serum triglycerides are independently associated with higher risk of developing metabolic syndrome. Both bilirubin and triglycerides can regulate insulin secretion and glucose uptake. This is a first longitudinal study in healthy children to associate bilirubin and the bilirubin/triglycerides ratio with metabolic markers.Objectives: Analyze independent associations between bilirub...

Placental Methylation in The IRS1 Gene is Associated with Obesity Parameters in 6 Year-Old Children Born to Mothers with Pre-Gestational Obesity

Gómez-Vilarrubla Ariadna , Mas-Parés Berta , Carreras-Badosa Gemma , Bonmatí Alexandra , Prats-Puig Anna , de-Zegher Francis , Ibañez Lourdes , López-Bermejo Abel , Bassols Judit

Background: Epigenetic alterations due to maternal obesity may contribute to an increased metabolic risk in the offspring. IRS1 has a critical role in insulin signalling and its methylation has been previously associated with body fat distribution and glucose metabolism in human adipose tissue. The relationship between IRS1 methylation in birth tissues and obesity parameters in the offspring is unknown.Objective: To iden...

Effects of Caloric Restriction During Gestation on the Methylome of Offspring’s Adipose Tissue and Reversibility of Such Effects by Metformin in a Swine Model

Introduction: Maternal caloric restriction during gestation leads to offspring’s metabolic programming through epigenetic changes, which increase the risk of developing cardiovascular diseases in adulthood.Objectives: To study in a swine animal model: i) DNA methylation changes associated with caloric restriction during gestation in the adipose tissue of the offspring; and ii) the reversibility of these changes by metformin treatment.<p class="a...

Expression of MIR-576-5p in Umbilical Cord as a Novel Biomarker for the Identification of Catch-up Growth in Small-For-Gestational-Age Infants

Background: Early catch-up growth, between birth and age two years, in infants born small-for-gestational-age (SGA) is a risk factor for the development of cardiometabolic diseases in adulthood. The basis and mechanisms underpinning catch-up growth in SGA newborns are unknown.Objectives: We aimed to investigate the catch-up predictive ability of cord blood miRNAs in SGA infants.Methods: MicroRNA PCR Human Panels were used to study ...

Background: The placenta plays a key role in regulating fatty acid (FA) transport from maternal to fetal circulation. An unfavourable FA profile in the placenta, reflecting an inadequate nutritional status during pregnancy, may cause changes in placental DNA methylation and negatively affect fetal growth and metabolic health of the offspring.Objectives: We aimed to study the association of an unfavourable placental FA profile with placental DNA methylati...
