Circulating GLP-1 in Infants Born Small-for-Gestational-Age: Breast-Feeding Vs Formula-Feeding

Diaz Marta , Bassols Judit , Sebastiani Giorgia , Lopez-Bermejo Abel , Ibanez Lourdes , de Zegher Francis

Background: Prenatal growth restraint associates with risk for later diabetes particularly if such restraint is followed by postnatal formula-feeding (FOF) rather than breast-feeding (BRF). Circulating incretins can influence the neonatal programming of hypothalamic setpoints for appetite and energy expenditure, and are thus candidate mediators of the long-term effects exerted by early nutrition.Objective, hypotheses and method: We have tested this conce...

The Sequence of Prenatal Growth Restraint and Postnatal Catch-Up Growth Leads to a Thicker Intima Media and More Pre-Peritoneal and Hepatic Fat by Age 3-6 Years

Sebastiani Giorgia , Diaz Marta , Bassols Judit , Lopez-Bermejo Abel , De Zegher Francis , Ibanez Lourdes

Background: Infants born small-for-gestational age (SGA) who develop postnatal weight catch-up are at risk for insulin resistance, central adiposity and cardiovascular disease in later life, even in the absence of overweight.Objective and hypotheses: In young (age 3–6 years) non-obese SGA children, we assessed arterial health by intima-media thickness (IMT) and abdominal fat distribution (subcutaneous, visceral, pre-peritoneal and hepatic components...

Circulating miR-451a: A Biomarker to Guide Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescent Girls

Díaz Marta , Bassols Judit , López-Bermejo Abel , de Zegher Francis , Ibáñez Lourdes

Polycystic ovary syndrome (PCOS) is a prevalent disorder in adolescent girls, commonly driven by hepato-visceral fat excess, usually presenting with hirsutism and menstrual irregularity, and often followed by subfertility and type 2 diabetes.We studied the miRNA profile of adolescent girls with PCOS, and the effects of randomized treatment with an oral contraceptive (OC) or with spironolactone-pioglitazone-metformin (SPIOMET, aiming at loss of hepato-vis...

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...

Circulating GDF15 Concentrations in Girls with Low Birth Weight and Precocious Pubarche: Effects of Prolonged Metformin Treatment

Díaz Marta , Carreras-Badosa Gemma , Bassols Judit , de Zegher Francis , López- Bermejo Abel , Villarroya Francesc , Ibáñez Lourdes

Background: Low birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and lowering body weight. We aimed to assess whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precociou...

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...

Low vitamin D levels are associated with markers of metabolic syndrome in children with newly onset type 1 diabetes mellitus

Puerto-Carranza Elsa , Muriscot-Niell Liria , Carreras-Badosa Gemma , De Zegher Francis , Lourdes Ibañez , Judit Bassols , Abel López-Bermejo

Background: Low vitamin D levels are prevalent in pediatric patients with type 1 diabetes mellitus (T1DM) and are associated with increased risk for insulin resistance, type 2 diabetes mellitus and cardiovascular disease. Little is known about associations between vitamin D levels and markers of metabolic syndrome in incident T1DM in children. The aim of our study was to analyze associations between D vitamin levels and metabolic markers in newly onset T1DM pe...

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

Bassols Judit , Mas-Pares Berta , Bonmati Alexandra , Xargay-Torrent Silvia , Carreras-Badosa Gemma , Lizarraga-Mollinedo Esther , Martinez-Calcerrada Jose-Maria , de Zegher Francis , Ibanez Lourdes , Lopez-Bermejo Abel

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 ...

Placental Fatty Acid Profile, DNA Methylation and Adverse Metabolic Outcomes in the Offspring at School Age

Bassols Judit , Xargay-Torrent Silvia , Mas-Pares Berta , Lizarraga-Mollinedo Esther , Prats-Puig Anna , Bonmati Alexandra , Martinez-Calcerrada Jose-Maria , Zegher Francis de , Ibanez Lourdes , Lopez-Bermejo Abel

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...

Preferential Paternal Transmission of the T Allele for the rs1802710 Polymorphism In Dlk1 Gene as a Pre- and Postnatal Growth Regulator

Prats-Puig Anna , Carreras-Badosa Gemma , Xargay-Torrent Silvia , Petry Clive J , Redondo-Bautista Lara , de Zegher Francis , Bassols Judit , Ibanez Lourdes , Dunger David B , Lopez-Bermejo Abel

Background: DLK1 or PREF1 is an imprinted gene highly expressed from the paternal allele in embryonic tissues and placenta. It has been recently implicated in adipose tissue expansion and diabetes development. The human rs1802710 polymorphism (SNP) in DLK1 gene has been associated with early-onset extreme obesity but its role determining growth is unknown.Objective and hypotheses: To study the preferential paternal transmission...
