Background: Several studies have shown that type 1 diabetes mellitus (T1DM) may contribute to the early onset or acceleration of cognitive impairment (intelligence, psychomotor efficiency, information management speed, visual attention, visual perception and cognitive flexibility). Tear proteomics seems to provide useful information for understanding the molecular mechanisms of various ocular and systemic diseases.Objective and H...

Mast cells are known to control mineralocorticoid synthesis and secretion in human normal adrenal gland and aldosterone-producing adenomas through release of serotonin. We recently detected these immune cells in human fetal adrenal from 18 weeks of gestation in the subcapsular layer, in correlation with the expression of steroidogenic enzymes required for aldosterone biosynthesis. This observation suggests the implication of mast cells in the mineralocorticoid synthesizing pat...

Overexpression of DYRK1A Located in the Down Syndrome Critical Region, Leads to Primary Hypothyroidism in Down Syndrome through Interaction with FOXE1

Kariyawasam Dulanjalee , Carre Aurore , Rachdi Latif , Polak Michel

Background: Down Syndrome (DS) patients have a higher incidence of primary hypothyroidism. We previously demonstrated that transgenic mice overexpressing Dyrk1A had developmental (larger primary thyroids at E15.5 stage of development), morphological (disorganized follicles) and functional (significant lower plasma T4) impairments similar to DS thyroidal impairments (Endocrinology 2015). DYRK1A, localized in the DS critical region on chromosome 21, is therefore the can...

A Multiplatform Non-targeted Metabolomics Approach to Investigate Insulin Resistance Associated to Obesity in Childhood

Mastrangelo Annalaura , Martos-Moreno Gabriel , Garcia Antonia , Ruperez Francisco , Chowen Julie , Perez-Jurado Luis , Barbas Coral , Argente Jesus

Background: Childhood obesity is often associated with insulin resistance (IR), which is a key risk factor for the development of comorbidities. The etiologic relation between insulin resistance and obesity is still not completely understood.Objective: In this study a multiplatform metabolomics approach was applied for the first time to elucidate the metabolic alterations in obese children with or without IR. Metabolomics is the revolutionary strategy of...

Gender Difference in Secular Trend in Sweden

Holmgren Anton , Niklasson Aimon , Nierop Andreas F M , Gelander Lars , Sjoberg Agneta , Aronson Stefan , Albertsson-Wikland Kerstin

Background, objective and hypotheses: By using QEPS, a new mathematic growth model, different components of growth can be analyzed, comparing secular trends of prepubertal and pubertal growth in Swedish birth cohorts born 1974 and 1990.Materials and methods: Two birth cohorts followed to adult height (AH) born around 1974 (1691 boys; 1666 girls) and 1990 (1647 boys; 1501 girls) being healthy, Nordic and born term. A subpopulation of 1974 (1177 boys; 1168...

Epidemiology of Turner Syndrome in Iceland 1968–2012

Sigmarsdottir Arndis Audur , Johannsson Johann Heidar , Sigurjonsdottir Helga Agusta , Thorsson Arni V

Introduction: Turner syndrome (TS) is a common genetic disorders with an estimated range of occuring in 25–210 per 100 000 liveborn females. In Denmark the prevalence of TS has been found to be 40 per 100 000 liveborn females. Our aim was to study the epidemiology of TS in Iceland for the period of 1968–2012.Methods: Primary source of data were hospital records and records from all pediatric endocrinologists in Iceland. To validate the data the...

Aldosterone and Mineralocorticoid Receptor as Inducers of Immune Markers in Peripheral Blood Mononuclear Cells: Beyond Elevating Blood Pressure

Background: In vitro studies suggest a broader role for aldosterone, beyond elevating blood pressure. Clinical data support the notion that aldosterone can directly alter the function of the immune system and can participate in low-grade inflammation which leads to blood pressure elevation and end organ damage.Objective and hypothesis: To assess in humans, whether aldosterone plasma levels and mineralocorticoid receptor (MR) expression associate...

RNA Sequencing Reveals the Pathways Perturbed by Redox Imbalance in Nicotinamide Nucleotide Transhydrogenase Null Mice

Meimaridou Eirini , Goldsworthy Michelle , Chortis Vasileios , Foster Paul , Arlt Wiebke , Cox Roger , Metherell Louise

Background: In humans, loss-of-function mutations in Nicotinamide nucleotide transhydrogenase (NNT) cause familial glucocorticoid deficiency, a potentially fatal, adrenal-specific disorder characterized by increased ACTH and reduced cortisol levels. NNT is a highly conserved inner mitochondrial membrane protein, which supplies high concentrations of NADPH for detoxification of reactive oxygen species (ROS) by glutathione and thioredoxin pathways.<p class="abstext"...

Childhood Obesity Negatively Influences Adult Leydig Cell Function

Wagner Isabel V , Kloting Nora , Kiess Wieland , Soder Olle , Svechnikov Konstantin

Background: Childhood obesity is a global health problem and co-morbidities develop already during childhood and adolescence. Male obesity impacts negatively on reproductive function. Testosterone is decreased, sperm quality reduced, and the physical and molecular structure of germ cells altered in obese males. However, less is known about the role of prepubertal obesity on future reproductive function. We therefore explored Leydig cell function and reproductive potential in a...

Background and Purpose: Previous studies have shown differences in serum, plasma, or saliva proteomics profile in patients with type 1 diabetes mellitus (T1DM), compared with healthy controls. The purpose of this prospective study is to identify the tear proteomics profile in children with T1DM that are followed at the Diabetes Center of the First Department of Pediatrics of the National and Kapodistrian University of Athens, at “Aghia Sophia” Chil...
