Purpose: To assess the prevalence in 2017 and elucidate the well-being of youngsters with gender dysphoria.Background: Gender dysphoria is described as a strong and persistent feeling of being born in the wrong sex. Often the feeling is associated with impaired ability to function in everyday life, found in children, adolescents and adults. For adolescents with gender dysphoria, puberty is an additional mental strain that can lead to depression, anxiety ...

Introduction: The goal of treating short children with growth hormone (GH) is to normalize adult height adjusted for mid parental height (MPH). We obtained adult height data on 87 patients (23 girls, 64 boys) treated with GH who originally participated in a randomized, prospective, open-label clinical trial with either personalized dose based on a prediction model (n=58), or standard dose (n=29). The children were either growth hormone defici...

Background: Simple clinical investigations to differ harmless premature thelarche (PT) from pubertal precocity and other pathological conditions are needed as PT is a common condition in girls under the age of 3–4 year.Objective and hypotheses: Since 17β-oestradiol (17β-E2) is the major driver of breast development, the hypothesis is, that it is possible to define an upper serum 17β-oestradiol (17β-E2) level for harmless PT in gi...

Background: Our first report of this randomized controlled trial (RCT) demonstrated improved treatment satisfaction but no difference in HbA1c between the CSII and MDI treated groups, and added to the controversy as to whether CSII improves HbA1c or not. Therefore, we thought it would be valuable to assess if CSII had other potential advantages and if our finding of lower insulin dose requirements could be explained.Objective and Hypotheses: To study how...

The development of the artificial pancreas or closed loop for type 1 diabetes, which started as a concept in the last century, took off once continuous glucose monitors became available. The first hybrid closed loop entered the market in 2016, where now several systems compete. This creates the ‘luxury problem’ of having to choose between different systems. Anonymized CGM data collection from company databases try to address the question whether performance in opti...

Background: The BoneXpert method for automated determination of bone age from hand X-rays has always included a determination of the Bone Health Index (BHI) from the cortical thicknesses in the metacarpals.Objective and hypotheses: The aim was to extend this so-called digital X-ray radiogrammetry method into adults, and present reference curves for BHI and three other indices: the metacarpal index, the Exton-Smith index and the volume-per-area (proportio...

Background: The BoneXpert method for automated determination of bone age (BA) from hand X-rays was introduced in 2009, covering the Greulich-Pyle BA range up to 17 years for boys and 15 years for girls.Objective and hypotheses: To present an extension of the BA range of the automated method up to 19 years for boys and 18 years for girls and to validate it against manual rating.Method: The extension was developed based on images fro...

Background: The BoneXpert method for automated determination of bone age from hand X-rays is based on machine learning, so it lends itself naturally to be improved by adding more training data and using better learning algorithms. Currently, version 2 is running in 145 hospitals across Europe, and a new version 3 is rolled out in 2019.Objective and Hypotheses: The aim was to validate version 3 against manual ratings in r...

Background: Somapacitan is a reversible albumin-binding growth hormone (GH) derivative developed for once-weekly administration in patients with GH deficiency (GHD). It consists of a human GH backbone, similar to endogenous human GH, with one amino acid substitution, attached to an albumin binder via a linker chain.Objective: Absorption, metabolism and excretion (AME) of somapacitan were investigated in a Phase 1 trial (...

Background: Klinefelter syndrome (KS) is a male genetic disorder defined by the karyo type 47,XXY. Adult males with KS are at increased risk for osteoporosis, based on androgen deficiency. Androgen replacement is standard in adolescent and adults with KS, but has not been used earlier in childhood. We performed a clinical trial to study the effects of childhood, low-dose androgen replacement on bone density in boys with KS.Objective and hypotheses: To me...
