Objectives: No validated achondroplasia (ACH)-specific patient reported outcome (PRO) or clinician-reported outcome (ClinRO) measures are available. A detailed review of generic PRO and ClinRO measures was performed to select relevant tools for further evaluation in a qualitative study.Methods: Published literature describing medical challenges and impacts among children with ACH was reviewed to identify important concep...

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...

Association between Hypothalamus–Pituitary Adrenal Axis Activity and Anxiety in Prepubertal Children with Type 1 Diabetes

Barat Pascal , Brossaud Julie , Bereron Aude , Corcuff Jean-Benoit , Moisan Marie-Pierre , Lacoste Aurelie , Vautier Vanessa , Savel Helene , Perez Paul

Background: Animal models of insulin-dependent diabetes show hyperactivity of hypothalamus–pituitary adrenal (HPA) axis, independently of hypoglycaemia. Few data exists regarding type 1 diabetes (T1D) in children.Objective: To describe HPA axis activity according to the anxiety levels in prepubertal T1D children.Method: Prepubertal T1D children and siblings of T1D children (controls) were included. State-Trait Anxiety Inventor...

Brain Structure and Function in Gender Dysphoric Adolescents

Hannema Sabine , Schagen Sebastian , Hoekzema Elseline , Kreukels Baudewijntje , Veltman Dick , Cohen-Kettenis Peggy , Bakker Julie , Delemarre-van de Waal Henriette

Background: Gender dysphoria is characterised by an incongruency between the perceived gender identity and the biological sex. The cause of gender dysphoria is unclear and environmental as well as genetic factors may be important. It is well known that during sexual differentiation sex steroids control not only the differentiation of the internal and external genitalia but also the sexual differentiation of the brain. Structural as well as functional differences have been show...

Being Overweight During the Peripubertal Period Modifies the Leptin Induced Changes in Hypothalamic Neuropeptides Involved in Metabolism but not those Involved in Pubertal Onset

Castro-Gonzalez David , Fuente-Martin Esther , Sanchez-Garrido Miguel A , Argente-Arizon Pilar , Tena-Sempere Manuel , Chowen Julie A , Argente Jesus

Background: Leptin is suggested to be a permissive factor in the onset of puberty by signaling at the level of the hypothalamus to indicate adequate energy stores. Overweight female rats due to increased neonatal nutrition have been shown to develop puberty before normal weight rats.Objective and hypothesis: We hypothesized that this permissive effect may be due not only to increased leptin levels, but also to increased hypothalamic sensitivity to this h...

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...

Triiodothyronine-Predominant Graves’ Disease (T3-P-GD): Description and Management in Childhood

Harvengt Julie , Boizeau Priscilla , Zenaty Delphine , Paulsen Anne , Simon Dominique , Crepon Sophie Guilmin , Alberti Corinne , Carel Jean-Claude , Leger Juliane

Background: T3-P-GD, a severe, rare disorder well known in adults, has not previously been described in children. It is characterized by persistently high serum fT3 concentration and normal, or even low, fT4 concentration during drug treatment. This condition is associated with very high titers of TRAb and large goiters, but its pathogenesis remains unclear. The recognition of this form of GD in children is of particular importance, as higher antithyroid ...

Activation of Insulin Signaling in Gastrocnemius after Central Leptin Infusion is Associated with an Increase in Proliferation and Muscle Fibre Size

Barrios Vicente , Burgos-Ramos Emma , Canelles Sandra , Rodriguez Amaia , Gomez-Ambrosi Javier , Chowen Julie A , Fruhbeck Gema , Argente Jesus

Background: Skeletal muscle is the largest tissue involved in the insulin-stimulated disposal of glucose, with its size being controlled by hormonal status, among other factors. Leptin plays a primary role in the regulation of glucose homeostasis with a substantial degree of insulin and leptin cross-talk in muscle. However, the relationship between the leptin’s central effects on insulin sensitivity in muscle and associated structural changes remain unclear.<p class="...

Management of Children with Type 1 Diabetes During Illness (Sick Days): Is There a Need for National Consensus Guideline?

Soni Astha , Agwu Chizo , Wright Neil , Moudiotis Chris , Kershaw Melanie , Edge Julie , Drew Josephine , Ng Sze May

Background: Adequate sick day management at home may reduce the risk of progression to diabetic ketoacidosis (DKA) and admission to hospital. The UK does not have a consensus guideline for sick day management advice to children and young people with type 1 diabetes mellitus (T1DM). Children’s diabetes services vary in their practice of education and advice in the use of urine or blood ketone monitoring during illness.Objective and hypotheses: The ai...

Acute Illness and Death in Children with Adrenal Insufficiency

Worth Chris , Vyas Avni , Banerjee Indraneel , Lin John , Jones Julie , Stokes Helen , Komlosy Nicci , Ball Steve , Clayton Peter ,

Background: Adrenal Insufficiency (AI) is a heterogeneous diagnosis comprising multiple central and peripheral causes. The unifying feature is the requirement for glucocorticoid replacement and subsequent risk of life-threatening Adrenal Crisis (AC) and Adrenal Death (AD). Very few studies have investigated rates of AD in children. Multiple studies have reported symptoms of children with AC as interpreted by medical staff but no studies have looked at parental...
