Context: In the newborn period, failure to thrive (FTT) with feeding difficulties and severe hypotonia are prominent in Prader-Willi syndrome (PWS). Despite the low weight, abnormal body composition is already present at birth in both children with FTT and those without. Limited studies reported the prevalence of FTT in infants with PWS and it has not yet been described whether GH-treatment has different effects in infants with FTT compared to those without.</...

Introduction: Hypogonadism affects almost all males with Prader-Willi syndrome (PWS) and is associated with decreased bone mineral density (BMD). Testosterone Replacement Therapy (TRT) improves BMD and aids sexual maturation, but TRT could aggravate challenging behaviour that many patients with PWS already suffer from, causing reluctance in starting TRT in males with PWS. This study aims to provide more evidence on the effect of TRT on behaviour, BMD and body ...

Background: Current guidelines suggest to test obese subjects with impaired fasting glucose (IFG) by oral glucose tolerance test (OGTT) for the presence of type 2 diabetes. This strategy, however, misses most cases of impaired glucose tolerance (IGT).Objective and hypotheses: To investigate whether combining risk factors improves predictability of IGT in OGTT.Method: In this observational study of 145 overweight children, aged 2.5&...

Background: Children with obesity show differences in brain structure, executive function and appetitive traits when compared to lean peers. Results of imaging studies, however, have been contradictory.Objective and hypotheses: To investigate whether childhood obesity is associated with differences in brain structure and whether differences associate with executive function and appetitive traits.Method: A cross-sectional case-contr...

Background: Childhood obesity is associated with advanced bone age (BA), leading to an altered growth pattern. Previous results of studies suggest that androgens, estrogens, sex hormone binding globulin (SHBG) and insulin are responsible for this phenomenon, but results are contradictory and might be biased by confounders.Objective and hypotheses: To investigate the independent effects of estrogens, androgens, SHBG and insulin parameters on BA advancemen...
