Neonatal Overnutrition Causes Sex and Age Dependant Long-Term Effects on Body Weight, Body Composition and Serum Triglyceride and Free Fatty Acid Levels

Argente-Arizon Pilar , Diaz Francisca , Fuente-Martin Esther , Chowen Julie Ann , Argente Jesus

Background: Neonatal over-nutrition (NON) can increase the propensity to become overweight and develop associated metabolic disturbances in later life. Moreover, some of these long-term effects are sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and triglyceride (TG) and non-esterified fatty acids (NEFA) levels. We hypothesized that the effects would be both age and sex dependant.<...

Free Fatty Acids Activate Hypothalamic Astrocytes in a Sexually Dimorphic Manner

Argente-Arizon Pilar , Fuente-Martin Esther , Diaz Francisca , Freire-Regatillo Alejandra , Argente Jesus , Chowen Julie A

Introduction: Obesity is known to associate with chronic systemic inflammation. However, hypothalamic inflammation also occurs in response to high fat diet (HFD)-induced obesity and is proposed to participate in central insulin/leptin resistance and the perpetuation of weight gain and systemic affectation. The weight gain and central responses to HFD differ between males and females. As hypothalamic glial cells are implicated in the central inflammatory response we hypothesize...

Neuroendocrine Dysfunctions Following Traumatic Brain Injury in Children: a 12-Month Prospective Study

Rojo Pilar , Carcavilla Atilano , Ortiz Irene , Arjona David , Borrego Raul , Aragones Angel

Background: Traumatic brain injury (TBI) is a frequent cause of endocrine dysfunctions. However, studies in children are scarce.Objective and hypotheses: To determine pituitary function in children after TBI. To analyze risk factors related with endocrine dysfunctions after 12 months follow up.Method: A prospective study of endocrine function in children after head injury was performed. Data was collected for baseline Glasgow coma ...

Palmitic Acid Could Modify Cognitive and Behavioural Functions Through Sex Specific Activation of Hippocampal Astrocytes

Frago Laura M , Freire-Regatillo Alejandra , Argente-Arizon Pilar , Argente Jesus , Chowen Julie A

Background: Prolonged poor dietary habits can result in hypothalamic inflammation and gliosis with more recent studies suggest that other brain areas may also be affected. Western or high fat diet intake has been associated with increased cognitive impairment and aberrant feeding behavior, with males and females being differentially affected. The hippocampus participates in both of these functions. Saturated free fatty acids can induce astrocyte inflammation and this could pot...

Long-Term Effects of Neonatal Over-Nutrition on Metabolic Equilibrium are Age and Sex Dependant

Argente-Arizon Pilar , Ros Purificacion , Diaz Francisca , Fuente-Martin Esther , Barrios Vicente , Chowen Julie A , Argente Jesus

Background: Neonatal over-nutrition (NON) can have a long-term effects on energy homeostasis and some of these effects may be sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and cytokine levels throughout development and if these changes are sexually dimorphic. We hypothesised that the effects would be both age and sex dependant.Methods: At birth, Wistar rats wer...

Inflammation associated to body composition in European prepubertal children: Results from the IDEFICS study

Argente Pilar , Esther Gonzalez , Intemann Timm , Moreno Luis , Molnar Denes , Kaprio Jaakko , Russo Paola ,

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...

PROP1 Mutations Cause Hypopituitarism by Disrupting the Transition of Pituitary Stem Cells to Differentiation

Millan Maria Ines Perez , Mortensen Amanda , Brinkmeier Michelle , Camper Sally

Background: Congenital multiple pituitary hormone deficiency (MPHD) arises from defects in pituitary development and is sometimes associated with craniofacial abnormalities. Mutations in the transcription factor PROP1 are the most common known genetic cause of the disorder. In this case the course of disease is progressive, and can lead to life threatening adrenal insufficiency.Objective and hypotheses: Our objective is to understand the role of PROP1 in...

Neurological Clinic Delays the Diagnosis of Pseudohypoparathyroidism

Teresa Perez Maria , Regina Labra , Zoa Garcia , Ana Llorente

Background: The pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of clinical entities caused by a defect in the peripheral action of parathyroid hormone (PTH). Biochemically it manifests itself with hypocalcemia, hyperphosphatemia and elevated PTH. PHP-Ia is the most frequent and multiple hormone resistance, associated signs of Albright hereditary osteodisfrofia (OHA) and mutations in the gene encoding GNAS Gsa protein.Case presentation: ...

Reference Values of Automated Bone Age and Bone Health Index for Mexican Children and Adolescents

Lora America Liliana Miranda , Espindola Montserrat Espinosa , Gonzalez Desiree Lopez , Loyo Mariana Sanchez-Curiel , Suarez Pilar Dies , Klunder Miguel Klunder

Background: BoneXpert is a software for automated measurement of bone age (BA) and radiogrammetry (bone health index). The precision error of the software for BA measure is smaller than the human rating error and the accuracy relative to the human routine ratings is 0.80 years. Differences in skeletal maturation between ethnicities have been reported, so it is important to have specific references for the own population.Objective: To present the automate...

LRH1 Rescues SF1 Deficiency for Steroidogenesis in vitro but Cannot Explain the Broad Phenotype of SF1 Deficiency in men

Camats Nuria , Fernandez-Cancio Monica , Audi Laura , Andaluz Pilar , Mullis Primus E , Carrascosa Antonio , Fluck Christa E

Introduction: Steroidogenic factor1 (SF1/NR5A1) regulates adrenal and sex development and function. SF1 mutations manifest with a broad phenotype; generally in 46,XY individuals with disorders of sex development (DSD) and in women with ovarian insufficiency. So far, no genotype–phenotype correlation has been found. We hypothesized that the broad phenotype of SF1 mutations may be due to a second hit in a gene with similar function. Liver receptor homolog-1 (LRH1/<...
