Background: Patients affected by pseudohypoparathyroidism type 1b (PHPI-b) develop resistance to PTH leading to hypocalcemia and hyperphosphoremia, which is often associated with resistance to TSH. PHP-Ib is associated with methylation changes at one or several differentially methylated regions (DMRs) within the GNAS complex locus, located at 20q13.2–13.3. This locus gives rise to several different transcripts (NESP55, XL, A/B), with varying patterns of imprinted expressi...

For the brain tumor committee of SFCE (Société Française des Cancers de l’Enfant).Objective: Therapeutic approach favors chemotherapy as the first-line-treatment in progressing OPG. There are few data on long term endocrine outcomes of aggressive OPG treated by upfront chemotherapy. Our main objective was to describe the long-term endocrine sequelae in these patients and to identify potential early predictors of the endocrine involvem...

Background: Patients with disorders of sex development (DSD) require multidisciplinary team management for etiology identification and gender assignment. Identification of mullerian structures is an important part of the evaluation process. Ultrasonography remains the first-line imaging modality to delineate mullerian structures; while the importance of magnetic resonance imaging (MRI) is insufficiently studied.Objective and hypotheses: To evaluate the d...

Background: There is limited information on the ability of demographic or lifestyle factors to predict short term changes in weight status during childhood.Objective and hypotheses: To study the effect of parental (educational level, BMI status and perception of child’s weight status) and childhood factors (eating habits, sedentary behaviour and physical activity), on 1-year BMI increments by the use of BMI, BMI SDS and BMI SDS conditional gain....

Background: Although metabolically obese normal weight (MONW) adults are at increased risk of type 2 diabetes and cardiovascular disease (CVD), little is known regarding MONW children.Objective and hypotheses: To characterize lifestyle habits and insulin dynamics of MONW children.Method: Caucasian youth (n=630) aged 8–10 years, with at least one obese biological parent, were studied (QUALITY cohort). We defined MONW c...

Introduction: Childhood obesity rates have increased exponentially in the past three decades. Parental characteristics, such as weight status, physical activity (PA), education and smoking habits have been identified individually as being potential determinants of offspring obesity. However, no prospective studies have examined the joint impact of parental lifestyle habits on their offspring's adiposity. We identified clusters of parental characteristics, ...

Introduction: People’s weight-related behaviors may be influenced by their personal social network (SN), notably via family and friends’ behavioral modelling and motivational social support (SS).Objective: We examined the cross-sectional relation between social network-based social support (SS) and weight-related outcomes among adolescents ina pilot study within the QUALITY cohort, a longitudinal study investigating the natural...

Background: Clinical assessment of pubertal breast development using Tanner staging is subjective. This has led to the introduction of ultrasound, aiming for a more objective analysis. However, information regarding its reliability is lacking.Objective: To examine intra- and inter-observer agreement of breast maturity staging using ultrasound, and to examine the precision of direct measurements of the gland.Materials and methods: F...

Background: Anthropometry is the general tool for defining overweight and obesity, with BMI cut-offs adjusted for sex and age, as the most commonly used variable in childhood.Objective and hypotheses: Based on the interrelationships between BMI and different overweight-related anthropometric variables we wanted to find out which anthropometric variables contribute most to the variation in BMI, and how age affect this picture?Method...

Background: Physical activity is beneficial to lipid profiles, however the association between sedentary behaviours and paediatric dyslipidaemia remains controversial. Understanding these associations is critical given that youth are increasingly engaging in sedentary pursuits, and are sleeping, on average, 1 h less than children were 20 years ago.Objective and hypotheses: To investigate whether various forms of sedentary behavior/sleep predict lipid pro...
