Background: The ACTION Teens study aimed to identify attitudes, behaviours and perceptions among adolescents living with obesity (ALwO), caregivers of ALwO (CGs) and healthcare professionals (HCPs) who treat ALwO. This subanalysis assessed the mental well-being and self-esteem of ALwO.Methods: ACTION Teens was a global, cross-sectional study (NCT05013359) that surveyed 5275 ALwO (aged 12–<18 years), 5389 CGs and...

Background: This subanalysis of the ACTION Teens study aimed to explore perceptions of obesity and food/diet among adolescents living with obesity (ALwO) and caregivers of ALwO (CGs) who were unaware of their/their child’s obesity.Methods: The global, cross-sectional ACTION Teens survey study (NCT05013359) assessed perceptions, attitudes and behaviours among 5275 ALwO (aged 12–<18 years), 5389 CGs and 2323...

Flash glucose monitoring is now included in the Portfolio of Services of the Public Health System of Andalusia in Spain. We enrolled 145 paediatric T1D diabetes patients into a prospective, interventional study of the impact of the FreeStyle Libre system on HbA1c levels in this population, as well as additional measures of glycemic health, such as Time in Range (TIR) and Time Below Range (TBR). Subjects were trained in use of the FreeStyle Libre system at the start of the stud...

Background: Several lines of evidence suggest that the adult pituitary contains a population of tissue-specific stem cells capable of differentiating into hormone-producing cells. Previously, we have shown that Sox2+ve cells are able to self-renew and differentiate in vitro, suggesting that this population of undifferentiated cells may contain stem cells in vivo. When targeted with oncogenic mutations adult stem cells can become cancer stem cells, able to self-renew and give r...

Background: Treatment with GH of children born SGA allows an increase in growth velocity (GV) and improves adult height. Increased insulin resistance has been described in these patients, which reverts after interrupting GH administration. However, long-term metabolic consequences are not clearly established.Objective and hypotheses: Describe insulin resistance (HOMA-IR index) and auxological development (GV and height) in SGA children treated with GH fo...

Background: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology has been attributed to hyperphagia and hyperinsulinaemia. The wider roles of oxytocin (OXT) in regulating appetite and weight have recently emerged in animal and human studies, but there is no human evidence that hypo-oxytocinaemia contributes to weight gain.Hypothesis: Hypo-oxytocina...

Background: Mouse studies have demonstrated the necessity of Sonic Hedgehog (SHH) for normal proliferation of Rathke’s pouch (RP) precursors. However, the possible function of SHH in pituitary cell specification remains to be assessed. Additionally, evidence suggests that SHH may be relevant in human adamantinomatous craniopharyngioma (ACP), a histologically benign, but clinically aggressive childhood tumour associated with high morbidity.Objective ...

Adamantinomatous craniopharyngiomas (ACPs) are clinically challenging tumours, the majority of which have activating mutations in CTNNB1. They are histologically complex, showing solid tumor component comprised of different morphological cell types (e.g. β-catenin accumulating cluster cells and palisading epithelium), surrounded by a florid glial reaction with immune cells, but also a cystic component. ACP cysts often exert substantial mass effect on critical str...

Background: Vitamin D is a pleiotropic hormone the deficiency of which is related with extraskeletal manifestations such as insulin resistance and cardiovascular risk disease.Objective and hypotheses: To investigate the levels of VitaminD in a sample of children with obesity and to evaluate the relationship between carbohydrate metabolism and metabolic syndrome (MS).Method: In this prospective cross-sectional study, 189 children ag...

Introduction: Small-for-gestionational-age newborns (SGA-NB) may present subsequent comorbidities affecting their metabolism, growth, and development. Analysis of changes in serum proteome profile expression in SGA-NB may provide physiopathological information and help to identify postnatal biomarkers.Aim: To compare serum proteome profiles in SGA vs AGA newborns, stratified by gestational age.Study population and method: The study...
