Background: Maternal overweight/obesity during pregnancy and excessive gestational weight gain (GWtG) have been recognized as important early-life risk factors for childhood obesity. We aimed to examine whether maternal BMI at 20 weeks of gestation and excessive GWtG were associated with alterations in body composition and metabolism in childhood in the offspring of primiparous mothers who participated in a randomised controlled trial of exercise regimen during pregnancy.<...

Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

Background and objective: Given phenotype variability as well as limited utility of conventional endocrine investigations in reaching the diagnosis in a 46,XY patient suspected of a disorder of sex development (DSD), there is an increasingly stronger argument for considering targeted genetic sequencing at an earlier stage of the evaluation process. This study focused on identifying the relationship between clinical examination, endocrine and radiological assessment, as well as...

Objective: We assessed whether beta-cell function progressively decreases over time with greater type 1 diabetes mellitus (T1DM) duration using a mixed-meal tolerance test (MMTT). We also assessed simpler and more practical surrogate parameters for clinical use.Methods: We studied 57 children and adolescents with T1DM in Hangzhou (China), mean age at diagnosis was 8.3 years (range 2.3 to 15.3 years), with an average diabetes duration of 2.5 years (range ...

A Novel Mutation in Eukaryotic Translation Initiation Factor 2 Subunit 3 (EIF2S3) is Associated with X-Linked Hypopituitarism and Glucose Dysregulation

Gregory Louise C. , Williams Hywel , Rahman Sophia , Ferreira Carolina B. , Alatzoglou Kyriaki S. , Kapoor Ritika R. , Hussain Khalid , Gaston-Massuet Carles , Kelberman Daniel , Qasim Waseem , Dattani Mehul T.

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...

The Anti-diabetic Drug, Metformin, Suppresses Adipogenesis through both AMP-activated Protein Kinase (AMPK)-dependent and AMPK-independent Mechanisms

Background and aim: Metformin is widely used in Type 2 diabetes, with increasing reports of a potential bone protective role. We investigated the role of AMPK in mediating the effects of metformin on mesenchymal stem cell (MSC) differentiation to either osteoblasts or adipocytes.Methods: Confluent mouse MSCs (C3H10T1/2), wild type (WT) and AMPK knockout (KO) mouse embryo fibroblasts (MEFs) were treated with metformin(500 μM), AMPK-activator A769662(...

Background: Published studies of radiologically confirmed fractures in sufficiently large cohorts of boys with Duchenne Muscular Dystrophy (DMD) are limited.Objective: To determine the incidence of fractures in a contemporary cohort of 91 boys with DMD managed in all Scottish centres.Method: Radiologically confirmed fractures were classified into vertebral fracture (VF) and non-VF in a retrospective audit of all boys currently mana...

Background: Hyponatremia is defined as a serum sodium level below 135 mEq/l. It is associated with increased morbidity and mortality. Hyponatremia has many causes and can be classified as acute/chronic or hypo/hypo/euvolemic. The main rule in fluid and electrolyte disorders (and especially in hyponatremia) is excluding hypothyroidism and hypocortisolism and then making the correct diagnosis. Hypothyroidism and hypocorticolism can also cause euvolemic chronic hyponatremia but t...

Background: An increasing need for non-invasive, out-patient based investigations has necessitated a re-evaluation of urinary gonadotrophins (uGn) for assessing puberty.Objective: Prospective evaluation of the relationship between first morning uGn measured by immunoassay and corrected for creatinine (uLH:uCr; uFSH:uCr), and basal serum gonadotropins (sLH, sFSH) and in response to LHRH stimulation test. Prospective evaluation of uGn trend in patients rec...
