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...

Congenital hypopituitarism: the role of genetics

Gil Poch Estela , Javier Arroyo Diez Francisco , Mendez Perez Pilar , Galan Gomez Enrique ,

Hypopituitarism refers to the insufficient secretion of one or more pituitary hormones. If default is present at the time of birth is called congenital hypopituitarism (CH). Causes of this are perinatal pathology and genetic alterations. The clinical presentation is heterogeneous. The diagnosis is made by clinical suspicion supported by hormonal determinations, brain imaging test (MRI) searching of structural defects and genetic study. The development of the pituitary gland is...

Differences in The Management of Classic Childhood Congenital Adrenal Hyperplasia in Spain According to A Patients Association

Murillo-Vallés , Valls-Llussà Aina , Martinez-Couselo Silvia , Salinas-Vert Isabel , de Diego-Suarez Marta Marta

Objective: Despite published guidelines, there is no single approach to management in congenital adrenal hyperplasia (CAH). The objective of the study was to explore the variations in treatment for CAH in Spain.Material and methods: A retrospective study in a single center was done analyzing the data provided by patients and relatives through the Spanish Association of CAH from a online survey of 25 questions. It was dif...

Comparison of Densitometric Aspects during the Transition Period in Patients with Congenital and Acquired Pituitary Deficiency: First Argentine Experience

Boquete Hugo , Boquete Carla , Ruibal Gabriela , Suarez Martha , Azaretzky Miriam , Nuñez Chavarria Eleonora , Sequera Ana , Fideleff Hugo

The transition phase is the period from the end of puberty until achievement of full adult maturity. We report the results from 45 patients with pituitary deficiency (15-24.9years), 28 (16males) with congenital insufficiency (G1) and 17 (10males) with acquired disease (G2), evaluated at the end of GH therapy. All cases had confirmed GH deficiency; 89.2 % of cases from G1 had multiple pituitary deficiencies (TSH 23/28, LH/FSH 19/28, ACTH 15/28 and Prolactin 3/28), 94.1 &#37...

Identification of the First Obesity-Associated Mutations in Human Mesoderm-Specific Transcript (MEST) Result in Protein Overexpression, Adipocyte Hypertrophy and a Reduction in Adipocyte Mitochondrial Area

Suarez Juan , Martos-Moreno Gabriel , Rivera Patricia , Serra-Juhe Clara , Chowen Julie , Perez-Jurado Luis , Argente Jesus

Background: Mesoderm-specific transcript (MEST) is an epoxide α/β-hydrolase protein with catalytic activity that is determinant for the development of adipocytes. The MEST gene is an imprinted gene transcribed only from the paternal allele. Although the mechanism by which MEST overexpression augments fat accumulation and storage in adipocytes has not been fully elucidated, frequent subcellular contacts between MEST-positive endoplasmic reticulum, mi...

Nonclassic Congenital Adrenal Hyperplasia and Functional Ovarian Hyperandrogenism Diagnosed During the Transition Period: Differences in Clinical, Hormonal and Metabolic Aspects

Introduction: Hyperandrogenism is a common presenting complaint during the transition period; however, clinical, hormonal and metabolic parameters in these patients have not been yet adequately characterized.Objective: To evaluate the disease-related history, clinical presentation and biochemical parameters in patients diagnosed during this period with nonclassic congenital adrenal hyperplasia (NCCAH) due to 21α hydroxylase deficiency and patients w...
