Background: Patients with Klinefelter syndrome (KS) have an increased risk for osteoporosis and fractures in adulthood. Data on bone mineralization in adolescence are limited, although it is a known at-risk period for vitamin D deficiency, low calcium intake and evolving hypogonadism.Objective and hypotheses: To study the bone mineralization in KS adolescents and its relationship with vitamin D/calcium and gonadal status. KS adolescents with low calcium ...

Background: Obesity in adolescence is associated with a 70% likelihood of obesity or overweight in adulthood. Hence, effective intervention programs for childhood obesity in high-risk populations are needed.Objectives: i) To compare the efficacy of two intervention strategies, involving parents only vs parent and child, to a control group, in the treatment of childhood obesity. ii) To identify clinical demographical and biochemical predictors for decreas...

Background: The most common form of congenital adrenal hyperplasia is 21-hydroxylase deficiency (CAH). In women with classic CAH, the fertility rate is lower than in the general female population, and an increased rate of miscarriages has been reported. There are no data on the incidence rate of miscarriages in families with an offspring that have classic CAH.Methods: The families came from different parts of Germany and attended the annual meeting of th...

Background: Differences in hypothalamus–pituitary–adrenal (HPA-)axis functioning have been proposed to underlie gender-specific cardiovascular and neurocognitive disease susceptibility.Objective and hypotheses: We conducted a systematic review and meta-analysis to test the hypothesis that gender-specific differences in HPA-axis activity are already present in childhood.Method: We searched two electronic databases (PubMed ...

Background: Bioavailability of peptide/protein – drugs is extremely low after oral administration due to their instability in the gastrointestinal tract or poor absorption.Objective and hypotheses: Oral delivery of growth hormone and somatostatin by adding extreme stable lipids.Method: A liposomal system based on a combination of standard lipids and membrane spanning tetraether lipids, which are extremely stable biomolecules. ...

Introduction: Limited research has focused on the potential connection between thyroid function and attention-deficit/hyperactivity disorder (ADHD), particularly beyond prenatal effects. The few studies addressing children and adolescents have important methodological shortcomings, mainly when seeking to establish causality. To clarify this relationship, a combined epidemiological and genetic approach was adopted to overcome the methodological limitations of e...

Introduction: Until recently, bariatric surgery (BS) has been the only option for clinically meaningful weight reduction for adolescents and youth with extreme obesity. Low participation rate in follow-up examinations and low supplement intake after BS in adolescents has been described in literature (PMID: 24048144, 25078533). We developed a structured pre- and post-bariatric surgery program in order to improve follow-up rate and supplement intake in adolescen...

Purpose: States of starvation are characterized by reduced physical activity and social withdrawal. The reduction of leptin levels during starvation has been proposed to be a mediator of these changes, therefore we aimed to ascertain if leptin substitution in patients with congenital leptin deficiency (CLD) can increase physical activity and improve mood.Methods: Seven CLD patients were filmed prior to and after short te...

Background: A fair number of epidemiological studies suggest that age at menarche (AAM) is associated with depression, but the reported effect sizes are small, and there is evidence of residual confounding. Moreover, previous Mendelian randomization (MR) studies to avoid inferential problems inherent to epidemiological studies have provided mixed findings.Methods: To clarify the causal relationship between age at menarch...

Background/Aim: Serum NAMPT (nicotinamide phosphoribosyltransferase) levels are altered in adult patients with non-alcoholic fatty liver disease (NAFLD). However, less is known about NAMPT serum levels children and adolescents and their association with parameters of liver function.Methods: Blood and anthropometric data of 416 children and adolescents who participated in the LIFE Child Study Leipzig were collected. Serum NAMPT (Adipogen) and cytokeratin-...
