Background: While differences in gut microbiota between obese and lean subjects have been described, few studies have examined how adiposity across childhood relates to intestinal microbiota composition and diversity in late adolescence.Objective: To explore the correlations between measures of adiposity from childhood and adolescence with intestinal microbiota composition and diversity at 15–17 years.Methods: Data stem from t...

Background: Dietary intake has been shown to influence the composition and diversity of the gut microbiota in adults, however its impact in childhood and adolescence remains uncertain. Moreover, the impact of other lifestyle behaviors such as physical activity, sedentary behaviors, sleep and fitness on the gut microbiota has rarely been investigated.Objective: To explore the correlations between intestinal microbiota composition and meas...

Background: Early life stress (ELS) are known to have a deleterious impact on health, but their potential long-term consequences on mortality remain to be assessed. World War 1 (WW1) has caused major stress and bereavement to millions of European mothers.Objectives and hypotheses: To compare the effects of a maternal stress occurring during intra uterine or in postnatal life upon long-term mortality.Patients: Thanks to recently dig...

Background: A common cause of neurodevelopmental impairment in children is congenital hypothyroidism, but can be preventable with adequate screening and proper management. Preterm newborns are more likely to have thyroid dysfunction, with small for gestational age (SGA) being an additional risk factor. However, only few studies addressed the altered thyroid hormone concentrations in the first few weeks of life concluding that Thyroid-Stimulating Hormone (TSH) levels are higher...

Background: Pediatric Endocrine Nurses are experts in caring for children with Endocrine conditions. Many nurses do not have the confidence, knowledge and technical skill set to produce poster presentations that allow them to share this expertise.Objective and hypotheses: This session will give Pediatric Endocrine Nurses an opportunity to hear how a poster presentation can be developed, from an idea to the final product. Nurses will feel empowered to tak...

Background: Increasing referrals for transgender youth demonstrated a lack of local interprofessional comprehensive programs for transgender youth. Pediatric endocrine clinics across Canada have collaborated with other disciplines to provide increasingly comprehensive assessment and treatment programs for transgender youth.Objective and hypotheses: Share a case study of a Canadian youth’s experience with the Gender Dysphoria Assessment and Action fo...

Introduction: The Body Mass Index (BMI) is an essential indicator for the nutritional assessment of children and reflects the exposure to health conditions that are harmful to the development of this population.Objective: To analyze the temporal trend of the BMI of Brazilian children, 0 to < 10 years old from 2010 to 2021.Methods: Descriptive ecological study. Data obtained from...

There are several different techniques for assessing bone strength and fracture susceptibility in children namely; dual-energy x-ray absorptiometry (DXA), quantitative computed tomography (QCT), plain radiography and magnetic resonance imaging (MRI). The most readily available technique and recommended by the International Society of Clinical Densitometry (ISCD) is DXA. The advantage of DXA is that it is widely available, affords the child a low radiation dose and can assess f...

Background: The Clock/Bmal1 transcription factor heterodimer regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes. 1,25 Dihydroxy Vitamin D (Vitamin D), a sterol hormone that is activated by exposure to sunlight, plays a fundamental role in maintaining calcium and phosphorus homeostasis. Recent evidence suggests that the nuclear vi...

Background: The circadian rhythm-generating peripheral Clock/Bmal1 heterodimer complex regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes.Objective and Hypotheses: To investigate the potential role of elevated cortisol in Clock/Bmal1 heterodimer complex-generated circadian biorhythms, both ...
