Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Background: Normal thyroid function is necessary for the optimal growth promoting effects of GH. Changes in the hypothalamic-pituitary-thyroid (HPT) axis following GH have been reported in subjects initially thought to be euthyroid. A specific group of patients, children with Prader-Willi syndrome (PWS), are thought to have a ‘vulnerable’ HPT axis.Objective and hypotheses: To evaluate the impact of paediatric GH therapy on thyroid hormone statu...

Context: Puberty timing is highly heritable. Recent genome-wide association studies, comparing timing of menarche in girls to timing of voice-break and facial hair in boys, revealed a largely overlapping genetic architecture of female and male pubertal timing. However, it is also known that genetic heterogeneity between sexes exists for some loci.Objectives: We hypothesized that self-reported relative parental pubertal t...

Introduction: Cryptorchidism has usually been managed using a surgical approach, with little attention to the underlying pathophysiology.Objectives: To assess gonadal function before treatment in prepubertal boys with cryptorchidism.Methods: In a cross-sectional study we reviewed all clinical charts of patients encoded with the diagnosis of cryptorchidism in the database of a paediatric tertiary hospital, between 2000 and 2017. Inc...

Background: Initiation and progression of puberty requires concerted action of activating and inhibiting factors. Recently, cases of central precocious puberty have been linked to loss-of-function mutations of makorin RING-finger protein 3 (MKRN3) indicating a pivotal inhibitory role of MKRN3 on GnRH secretion.Objective and hypotheses: To investigate peripubertal circulating MKRN3 levels in healthy boys.Method: Healthy boys (n<...

Introduction: Type 1 diabetes has a major impact on not only the person diagnosed, but also their families/carers. Diabetes control is affected by many factors. Our diabetes patient cohort has a very high level of social burden which we feel impacts significantly on the management of their diabetes.Methods: We performed a retrospective analysis of all young people supported by the Evelina London Children’s Hospital diabetes team in 2017 looking at a...

Background: Optimal glycemic control in children and adolescents with type 1 diabetes mellitus (T1DM) is often hampered owing to psychologic maladjustment of both patients and their parents. Accumulating evidence suggests that hyperglycemia may be associated with prolonged activation of the stress system.Objective and hypotheses: To pilot test a 12-week intervention program including psychoeducation about stress, healthy lifestyle, diaphragmatic breathin...

Introduction:The incidence of obesity increases unstoppably in all populations and at all ages, and with it, the associated metabolic morbidity and mortality. The promotion of physical activity and a healthy diet are the fundamental elements to alleviate this situation. The objective of this study is to determine the relationship of physical activity and eating patterns with body composition, the degree of adiposity and certain metabolic risk factors.<p cl...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

Introduction: The highest prevalence of children and adolescents with obesity in Europe is observed in the south countries. This epidemic is related to unhealthy eating patterns, decreased physical activity and increased inactivity.Objective: To determine the relationship between adiposity degree and physical activity and inactivity in children and adolescents.Methods: 338 children from 6 to 8 years of age (x=11.11 years);...
