Background: Over the last 60 years body composition of young people have changed towards increased fatness. Whole body fat percentage (%BF) derived from dual energy X-ray absorptiometry (DXA) scans are (although often not available) widely recognized as a better measure of fatness than BMI.Objective: We aimed to provide reference materials for %BF of healthy Danish children evaluated by skinfold measurements and DXA and to compare sensitivity and specifi...

Background: Little is known about the possible deleterious effects of phthalate exposure on endogenous sex steroid levels in childrenDesign: A longitudinal study.Materials and methods: 168 Healthy children (84 girls) were examined every 6 months for 5 years, with pubertal staging, measurements of serum levels of DHEAS and Δ4-androstenedione (Adione) and repetitive longitudinal morning urinary measurements of 14 phthalate metab...

Objectives: THRA mutations cause Resistance to Thyroid Hormone α (RTHα), an underdiagnosed disorder with hypothyroid features but near-normal thyroid function tests (TFTs). We developed a pathway, combining molecular analyses, new biomarkers and physiological measurements, to better diagnose and treat this disorder.Methods: Structural and functional analyses of THRA variants, discovered by next generation sequencing in specifi...
