Introduction: Cortisol secretion is circadian-driven and plays a significant role in sleep quality. In children with congenital adrenal hyperplasia (CAH) hydrocortisone is the preferred treatment. Hydrocortisone has a short half-life producing alternating hyper- and hypocortisolemia, a non-physiologic cortisol profile, likely disrupting sleep. However, minimal literature exists on sleep health in children with CAH.Objective:</str...

Introduction: Reliable reference values for thyroid ultrasound measurements are essential to effectively guide individual diagnostics and direct health care measures at the population level, such as iodine fortification programs. However, the latest reference values for total thyroid volume (Tvol) provided by the WHO in 2004 are only applicable to the 6 to 12-year-old age group. Moreover, these values are derived from countries with a long history of iodine su...

An oral GH secretagogue (GHS), LUM-201, stimulates GHSR-1a receptor to enhance endogenous GH pulsatile release. In moderate iPGHD, pulses of GH are found but at reduced levels, resulting in decreased IGF-1 and poor growth. The impact of LUM-201 on GH profiles during treatment of such children has not been reported.Objective: To characterize GH profiles, defined by deconvolution analysis, based on GH concentration in a time series and its...

Obesity in adolescents is associated with increased risk of prediabetes and type 2 diabetes (T2D) and long-term complications in adulthood. Data regarding the effects of anti-obesity medications on glycaemic outcomes in adolescents are sparse. STEP TEENS (NCT04102189), a phase 3a, double-blind, placebo-controlled randomised trial in adolescents 12 to <18 years of age with obesity demonstrated that once-weekly subcutaneous semaglutide 2.4 mg provided a greater percentage red...

Growth hormone (GH) stimulates insulin like growth factor I (IGF I) release. IGF-I is the standard biomarker for monitoring GH effects during treatment and to achieve optimal long-term safety, and to a limited extent, monitor efficacy in children with GH deficiency (GHD). The IGF I profile during treatment with a long acting GH (LAGH), such as once weekly somapacitan (Novo Nordisk), differs from the daily GH profile by exhibiting larger peaks and troughs over the dosing interv...

Background: Pubertal timing varies considerably and has been associated with a range of health outcomes in later life.Methods: To elucidate the underlying biological mechanisms, we performed multi-ancestry genetic analyses in ~800,000 women.Results: We identified 1,080 independent common genetic signals associated (at P<5×10-8) with age at menarche. Collectively t...
