Background: The condition when a person’s gender identity does not match the gender assigned at birth is called gender incongruence (GI). GI numbers increased tremendously over the last decade. Diabetes mellitus – type 1 and type 2 – is a severe and lifelong disease. GI combined with diabetes may potentiate the burden for affected people.Objective: The study aimed to characterize people with GI and diab...

Introduction: The prevalence of pediatric type 2 diabetes (T2D) increased over the last 2 decades, related to the rise in obesity. Meanwhile, treatment options for T2D have evolved considerably. Therefore, we analyzed changes in treatment approaches for pediatric T2D over two decades.Material and Methods: Patients with T2D from 321 pediatric diabetes centers (Austria 24, Switzerland 2, Luxemburg 1, Germany 290) were reco...

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

Objective: The treatment of children with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) is a challenge since both undertreatment and overtreatment with glucocorticoids can affect growth. Numerous reports in the literature have shown that the linear growth of individuals with CAH is affected and adult height is compromised. However, most of these data were obtained in the era before CAH newborn screening....

NMDA (N-Methyl-D-aspartic acid) receptors have been shown to control the timing of sexual maturation in laboratory animals. Therefore, variants in genes impacting NMDA receptor signaling might be predicted to affect human puberty. We studied an extended family with extremely delayed puberty (menarche at 16.5 - 18 years for female family members and pubertal onset at 16 years for male family members). Exome sequencing revealed a rare missense variant (F900V) in DLG2, w...

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...

Stress is increasingly associated with cardiac disease. Glucocorticoids are primary stress hormones that regulate homeostasis through two nuclear receptors, the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Cardiomyocytes express both receptors but little is known concerning their specific and coordinated actions in heart physiology and pathology. To examine the in vivo function of glucocorticoid signaling in the heart, we generated mice with cardi...

Background: The pathophysiological mechanism of skeletal fragility in Duchenne Muscular Dystrophy (DMD) is unclear.Objective: To compare trabecular bone microarchitecture, cortical geometry, muscle area and fat fraction (FF) at distal femur and vertebral bone marrow adiposity (BMA) between DMD and controls.Method: Bone-muscle and muscle FF were assessed using 3T MRI and Dixon technique. BMA was assessed using 1H-MRS. Results expres...
