Introduction: The clinical hallmark of male puberty is testicular enlargement ≥4 ml. While this initial sign largely depends on central reactivation of the hypothalamic-pituitary-gonadal (HPG) axis along with peripheral follicle-stimulating hormone (FSH) action, the attainment of voice-break, activation of sweat- and sebaceous- glands, acne as well as axillary hair development require testosterone action.Objective: To investigate the tempo...

Background: FSH stimulates ovarian follicle maturation and estradiol synthesis which is responsible for breast development. Age at pubertal onset varies substantially among healthy girls. Although more than half of the variation is heritable, only a small part has been attributed to specific genetic polymorphisms identified so far.Objective and Hypotheses: We assessed the effect on pubertal onset of three genetic polymorphisms affecting FSH action.<p...

Background: Studies in adults with type 1 diabetes (T1D) have indicated that adiponectin is negatively associated and leptin positively associated with measures of a residual beta cell function (RBF).Objective and hypotheses: To compare serum adiponectin and leptin levels and their ratio in children with T1D for 3–5 years with and without RBF and in healthy children.Method: We included 342 children (173 females) with T1D, here...

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...

Background: Normal function of the thyroid gland is essential for adequate neurological development of the fetus and child. In previous studies, associations between reduced birth weight and overt maternal and fetal thyroid dysfunction have been described. We hypothesize that also variations within the normal range of fetal thyroid function have an impact on fetal and neonatal growth.Objective: The aim of this study is to investigate whether thyroid horm...

Introduction: Physical growth according to genetic potential is a hallmark of childhood health [1]. Childhood growth is complex and the physiological processes involved in promoting healthy growth are not fully understood, including the gut microbiota. The gut microbiota matures from birth towards adulthood, and this process might be affected by several factors, including mode of delivery, food intake and antibiotic treatment. The bacterial gut microbiota is observed to be mor...

Background: There is a rise in overweight and obesity among children and adolescents with type 1 diabetes (T1D) in parallel with a rise in the metabolic syndrome (MS) among children and adolescents in general.Objective: The aim of the study was to describe the prevalence and characteristics of the MS in children and adolescents with T1D compared to their healthy counterparts.Design and Sett...
