Background: Disorders/Differences of Sex Development (DSD) is diagnosed in approximately one out of 4'500 newborns. Children born with DSD present with a very diverse phenotype and they and their families face considerable challenges, potentially including surgical intervention and gender assignment, as well as associated complications such as infertility and predisposition to gonadal tumors. Due to the lack of knowledge concerning the complete gene and pr...

Background/Introduction: Whole exome sequencing (WES) revolutionized clinical genetics in patients with differences of sex development (DSD). However, our ability to interpret WES data is limited by our incomplete understanding of the mechanisms involved in DSD. Thus, we created a methodology that scores potential candidates based on single cells transcriptomics of human male gonadal cells and applied it to WES data from a cohort of genetically male (46,XY) DS...

Although Endocrinologists have focused for decades on circulating concentrations of cortisol, arguably the important concentrations are those within tissues which are available at corticosteroid receptors. Tissue concentrations are influenced by plasma proteins binding cortisol, by physicochemical characteristics of the steroid, by active transport across cell membranes, and by steroid metabolism within target tissues. Many of these factors vary between individuals, and within...

Background: Glucose monitoring is vital in children with persistent hypoglycaemia to reduce the risk of adverse neuro-behavioural outcomes1. Continuous glucose monitoring (CGM) systems provide real-time glucose levels however; information on its usefulness in monitoring glucose levels in this cohort is limited2, 3.Objective: To ascertain the effectiveness of CGM and to evaluate parents’ experie...

Gestational Diabetes (GDM) increases risk of developing type 2 diabetes in the mother and child later in life however, despite the increasing prevalence of GDM, its molecular mechanism remains unknown. A recent Genome-Wide Association Study (GWAS) identified a unique genetic association of the novel 5th hexokinase, hexokinase domain component-1 (HKDC1) to gestational glucose tolerance at 28 weeks of gestation linking it to GDM. We have previously shown that liver-specific over...

Introduction: 6 Mercaptopurine (6MP) is a cornerstone of maintenance therapy in pediatric acute lymphoblastic leukemia (ALL). Fasting hypoglycemia is a rare side effect of 6MP therapy that has been observed in children being treated for ALL. We present two pediatric patients who developed symptomatic, fasting hypoglycemia during maintenance therapy.Case Description: A 7-year-old male with standard risk B ALL receiving ma...

Encouraged by unimolecular dual incretin co-agonists (GLP1/GIP) to enhance glycemic efficacy (Finan et al. 2013, Sci Transl Med) and GLP1/glucagon co-agonists to enhance weight loss efficacy (Day et al. 2009, Nat Chem Biol) and to restore diet-induced leptin sensitivity (Clemmensen et al. 2014, Diabetes), we recently developed the first tri-agonist (GLP1/GIP/glucagon) for the treatment of metabolic disorders (Finan et al. 2014, Nat Med). Importantly, this concerted triple agon...

Introduction: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Despite current treatments, patients/caregivers report continued hypoglycemia according to the HI Global Registry 2020 Annual Report. Published literature characterizing hypoglycemia in CHI patients on standard of care (SOC) therapies is lacking.Objective: To quantify the extent of hypoglycemia in CHI...

Background: Obesity interventions often result in increased motivation to eat after weight loss.Objective: We investigated relationships between obesity outcomes and changes in brain activation by visual food cues and hormone levels in response to obesity intervention by family-based behavioral treatment (FBT).Design, Methods, and Participants: Functional neuroimaging and plasma ho...

Background: Measurement of salivary glucocorticoids is an accepted method for testing adrenal function and is gaining popularity as it offers a non-invasive collection technique, enabling sampling in the community or home environment, allowing tailored capture of steroid circadian rhythm and improved patient experience. However, there is little data on stability during home collection and sampling methods in young children. Current salivary collection techniqu...
