Background: Maternal obesity can have long-term consequences for the offspring’s health, including increased risk of type-2 diabetes and cardiovascular disease. The C19MC imprinted locus on chromosome 19q13.4 comprises a cluster of 46 microRNAs, which are usually expressed only in the placenta and from the paternal allele exclusively. Besides its role favouring trophoblast migration, the C19MC locus is deregulated in several human cancers. It is unknown ...

Background: Individuals with the ultra-rare genetic disorder FOP experience progressive heterotopic ossification. Median age at diagnosis is 5 years; patients are supported by multiple specialties. Most patients become immobilised by the third decade of life, requiring lifelong assistance. We characterise AADA use as an indicator of disease severity in younger individuals with FOP enrolled in a 36-month, prospective, global NHS (NCT02322255).<p class="abst...

Introduction: Paediatric Inflammatory Multisystem Syndrome Temporarily associated with SARS-CoV-2 (PIMS-TS) was first reported by our hospital in the UK. Vitamin D3(25(OH)D) has important roles in cardiac function, immunomodulation, and inflammation. It therefore may be an important biomarker for severity in PIMS-TS, however 25(OH)D status and treatment guidance in PIMS-TS are lacking. We report serum 25(OH)D levels on admission and associations wit...

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification. The median age at diagnosis is 5 years and patients are supported by multiple specialties. We describe normal long bone growth changes and incidence of bone abnormalities in participants with FOP aged <18 years in a 3-year, prospective, global NHS (NCT02322255).Methods: Individuals with FOP age...

Background: Thyroid hormones contribute to a wide range of physiological processes and health outcomes. Epigenetic regulation of thyroid development and function has been little explored. PAX8 (Paired Box 8) is a thyroid transcription factor implicated in thyroid gland development and differentiation. PAX8 gene methylation appears to be sensitive to the environment in early pregnancy.Methods and Findings: Using a recall-by-epige...

Background and Aims: Central Precocious Puberty (CPP) caused by the early activation of the hypothalamic-pituitary-gonadal axis is a rare affection that occurs in 0.2% in girls. Clinical signs are suggestive and LHRH-test could be sometimes difficult to use and not always contributive. Gonadotropin assay in twenty-four hours-urinary collection could be an interesting option. The present work intended to evaluate the diagnostic interest of 24-hour urinary gonad...

Here we identified and characterized a heterozygous tandem duplication at the ASIP (agouti-signaling protein) gene locus causing ubiquitous, ectopic ASIP expression in a female index patient with extreme childhood obesity. In patient-derived adipose tissue samples, we observed pronounced differentiation of stroma-vascular fraction (SVF) cells into adipocytes in the patient compared to normal control cells. We further found reduced mitochondrial maximum respir...

Objectives: To discuss all challenges involved with providing children (including the very young) and adolescents with diabetes (CwD) with the latest appropriate technology, such as automated insulin delivery systems (AIDs), to manage their blood glucose and help improve their quality of life and suggest ways in which access to new types of devices available to adults can be improved for children with T1D.Methods: In con...

Background: Puberty is reported to be impaired in children with Sickle cell Anemia (SCA). Studies about this topic are rare in Sub-Saharan regionObjective and hypotheses: Assessment of pubertal development of children with SCA compared to healthy children in Mother and Child Center, CHANTAL BIYA Foundation.Method: We matched a group of 64 children with SCA (26 males, 38 females) with 94 healthy controls aged of 8–17 years old....

Background: Recently we demonstrated that male adolescents with severe GHD (sGHD) had a significant decrease of lean body mass and increase in fat mass after stop of GH-therapy. The functional consequence of this observation is unknown.Objective and hypotheses: The aim was to study the changes in parameters of jumping mechanography in adolescents with GHD in the transition period (end of growth) after stop of GH-therapy.Patients an...
