Recognition of a Sequence: More Growth before Birth, Longer Telomeres at Birth, More Lean Mass after Birth

de Zegher Francis , Diaz Marta , Lopez-Bermejo Abel , Ibanez Lourdes

Background: Telomere length at birth is a major determinant of telomere length in late adulthood. However, the prenatal setting of telomere length is poorly understood. Individuals born large from non-diabetic mothers are at lower risk for later-life disorders than those born small, a feature of their longer health span being a higher lean mass that provides more muscle strength and that is already present in infancy.Objective, hypotheses & methods: ...

Low-dose pioglitazone for polycystic ovary syndrome in adolescent girls:differential fat-mass redistribution by HOTAIR rs1443512 genotype

de Zegher Francis , Diaz Marta , Ibañez Lourdes

Introduction: Adolescent polycystic ovary syndrome (PCOS) is characterized by androgen excess and oligo-amenorrhea, and often results from ectopic lipid storage due to a mismatch between early adipogenesis and later lipogenesis. Endogenous HOTAIR and exogenous pioglitazone are enhancers of subcutaneous adipogenesis, particularly in the gluteofemoral region. The A allele of HOTAIR rs1443512 is an equivalent of a natural knock-down and is thus a candidate to inf...

Ovarian AMH production is transiently affected in pubertal and prepubertal girls with acute lymphoblastic leukaemia and non-Hodgkin lymphoma receiving chemotherapy: a prospective, longitudinal study.

Gabriela , Gryngarten Mirta , Soria Marcela , Moran Lorena , Ferraro Cristina , Freire Analia , Bergada Ignacio , Drelichman Guillermo , Aversa Luis , Rey Rodolfo A. , Grinspon Romina P. ,

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Testicular function in prepubertal boys with haematological malignancies during and post chemotherapy: a prospective, longitudinal study

Rey Rodolfo , P. Grinspon Romina

Introduction: Haematological malignancies represent the most frequent cancer in children. While there is an extensive literature on testicular function in adult survivors of childhood cancer, focused on sperm and androgen production, scarce information exists on the immediate impact in prepubertal boys.Aim: To characterise testicular function, focused on Sertoli cell biomarkers, from diagnosis up to 3 years after the end...

Short stature and efficacy of growth hormone treatment in a child with Nail-Patella Syndrome. A case report.

Pankratova Maria , Kareva Maria ,

Background: Nail-Patella syndrome (NPS) or hereditary onycho-osteodysplasia (OMIM: 161200) is an autosomal dominant disorder characterized by nail and elbow dysplasia, patellar aplasia or hypoplasia, nephropathy and intra-ocular hypertension. The diagnosis confirmes by pathogenic variant in the LMX1B gene. There are reports of short stature in patients with this syndrome, however, data of the use of somatropin have not been presented. We describe the ...

Maternal Resveratrol Intake During Pregnancy and Lactation Modulates the Long-term Metabolic Effects of Maternal Nutrition on Offspring Depending on the Sex and Diet

Ros-Perez Purificacion , Diaz Francisca , Freire Alejandra , Argente-Arizon Pilar , Argente Jesus , A. Chowen Julie

Maternal nutrition can have significant long-term consequences on energy homeostasis in the offspring. However, whether resveratrol, with antioxidant and anti-obesity actions, can improve the impact of poor maternal nutrition on offspring metabolism remains largely unknown. We hypothesized that resveratrol intake by dams would protect the offspring against the harmful effects of a maternal high fat diet (HFD). We also determined if resveratrol’s effects are diet and sex d...

Sexual Dimorphism of IGF1 and IGF2 Expression in the Neonatal Rat Brain

Guerra-Cantero Santiago , Torrecilla Marta , Diaz Francisca , Argente Jesus , Chowen Julie

Insulin-like growth factor (IGF) 2 plays a fundamental role in prenatal growth and development. The IGF2 gene is imprinted, with the paternally inherited copy being active and the maternal copy being silenced in most tissues. During development, the expression of IGF2 is sexually dimorphic in some tissues and this is thought to be involved in the development of some sexually dimorphic features. For example, IGF2 expression is reported to be higher in the male brain co...

Evaluation of a Novel Method to Detect Residual ß-Cell Function by Dried Blood Spots in Children and Adolescents with a Recent Diagnosis of Type 1 Diabetes

Willemsen Ruben , Burling Keith , Ackland Fran , Edge Julie , Diaz Renuka , Barker Peter , Guy Catherine , Dunger David

Background: The majority of drug developments in type 1 diabetes (T1D) are aimed at preventing decline of beta cell function (BCF), as this has been associated with better glycaemic control and fewer long-term complications. Traditionally, BCF is evaluated by the C-peptide response to the labour-intensive mixed-meal-tolerance-test (MMTT), but there’s a need for a more practical alternative. We developed a new method to measure C-peptide in ‘dried blood spots’ (D...

Trabecular Bone Score in Children from Mexico City: Preliminary Report

Angel Guagnelli Miguel , Gomez-Diaz Rita , Ambrosi Regina , Winzenrieth Renaud , Clark Patricia

Background: Trabecular Bone Score (TBS) is a software-based tool for analysis of DXA images to assess bone microarchitecture in the lumbar region. Several studies have addressed its value in adult population, however, little research has been done in children in which may be useful for bone evaluation during growth.Objective: To evaluate bone density and TBS during childhood and its relationship to other variables such as bone age and height<p class=...
