Designing monomeric dual or triple agonists based on glucagon-like peptide (GLP)-1 with glucagon, and/or glucose-dependent insulinotropic polypeptide (GIP) are promising novel approaches for anti-obesity drugs tackling different weight-regulatory pathways, albeit such developments continue to suffer from significant gastrointestinal illnesses. Our own studies have focused instead on the combination of GLP-1 receptor agonists (GLP-1RAs) with neuropeptide Y1- and Y2-receptor (Y1...

Cerebral perfusion following childhood-onset craniopharyngioma and the relationship with metabolic rate

Elsworth Rebecca L. , Naeem Nimra , Hawton Katherine , Narayan Kruthika , Elson Ruth , Taylor-Miller Tashunka , Lithander Fiona E. , Hamilton-Shield Julian P. , Crowne Elizabeth C. , Hinton Elanor C.

Background: Craniopharyngioma is a non-malignant embryonic tumour in the pituitary-hypothalamic area, associated with hypothalamic obesity. Dysfunctional parasympathetic nervous system activity has been proposed as one mechanism underlying alterations in energy metabolism. Arterial spin labelling (ASL) is a non-invasive MRI technique that quantifies brain tissue perfusion as a proxy for functional activity. Here, we measure cerebral perfusion in patients with ...

Characterisation of the first heterozygous missense HMGA2 variant helps delineate the crucial functional roles of a novel growth gene

Background: Silver Russell syndrome (SRS) is genetically heterogenous and around 30% of patients with clinical SRS have no genetic diagnosis. Mutations in HMGA2 have recently been identified causing growth failure and an SRS-like phenotype. Despite strong evidence of the crucial role of HMGA2 in growth across species, the mechanism of action of HMGA2 in human linear growth is unclear.Objective:...

Circulating Growth-and-Differentiation Factor-15 in Early Life: Relation to Prenatal and Postnatal Size

Díaz Marta , Campderrós Laura , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...

The Association Between IGF-1 levels and Nonalcoholic Fatty Liver Disease (NAFLD) in Adolescents with Type 2 Diabetes

Orozco Morales Jose Antonio , Torres Tamayo Margarita , Suárez Pilar Dies , López Martínez Briceida , Liliana América , Medina Bravo Patricia Guadalupe

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The mechanisms responsible for the development of nonalcoholic fatty liver disease (NAFLD) and progression to nonalcoholic steatohepatitis (NASH) in these patients are incompletely understood. Low serum insulin-like growth factor-1 (IGF-1) levels are associated with increased histologic severity of NAFLD. Growing evidence suggests that growth hormone (GH) and IGF-1 may have r...

GHR Transcript Heterogeneity May Explain the Phenotypic Variability in Patients with Homozygous GHR Pseudoexon (6ψ) Mutation

Chatterjee Sumana , Rose Steven J , Mushtaq Talat , Cottrell Emily , Maharaj Avinaash V , Williams Jack , Savage Martin O , Metherell Loiuse A , Storr Helen L

Objectives: The homozygous GHR pseudoexon (6ψ) mutation leads to aberrant splicing of the GHR gene with clinical and biochemical heterogeneity. We investigated whether the phenotypic variability could be explained by transcript heterogeneity i.e. ratio of abnormal (6ψ GHR) to normal (WT GHR) transcripts and/or the presence of concurrent defects in other short stature (SS) genes.Methods: 6&#968...

References for Testicular Volume Measured by Ultrasound and for Pubic Hair in 6-16 Year-Old Norwegian Boys

Oehme Ninnie B. , Roelants Mathieu , Bruserud Ingvild S. , Madsen André , Eide Geir Egil , Bjerknes Robert , Rosendahl Karen , Júlíusson Pétur B.

Objective: Recent studies have suggested earlier onset of pubertal development in boys. As assessment with orchidometer tends to overestimate true testicular volume (TV), and measurements based on ultrasound (US) have been proposed as a more reliable method, we present US based references in 6-16 year-old Norwegian boys. Our results are compared with data from Europe and the United States (U.S.) in order to establish evidence for an ongoing secular trend in ma...

Novel Pubertal References for Girls Using Ultrasound to Stage Breast Development. The Bergen Growth Study 2

Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...

Endocrine Profiling and Association with Ultrasound Measured Testicular Volume and Biometrics in a Cohort of Norwegian Boys

Madsen André , Oehme Ninnie , Bruserud Ingvild , Roelants Mathieu , Sagen Jørn , Mellgren Gunnar , Júlíusson Pétur

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...

ABCC8 MODY in an Obese Adolescent Misdiagnosed with Type 2 Diabetes

Filibeli Berna Eroglu , Çatli Gönül , Manyas Hayrullah , Ayranci Ilkay , Kaya Özge Özer , Dündar Bumin

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...
