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: The noncoding RNA growth-arrest-specific transcript 5 (Gas5) is abundant in cells whose growth has been arrested owing to lack of nutrients or growth factors. Gas5 is a riborepressor of the glucocorticoid receptor, influencing cell survival and metabolic activities during starvation by inhibiting the latter’s transcriptional activity.Aim: To determine the expression levels of Gas5 in blood samples of obese, overweight and lean children a...

Objective: evaluate insulin resistance (IR) in children and adolescents with exogen-constitutional obesity (ECO) depending on the stage of sexual development.Materials and research methods: 100 children and adolescents with ECO of the UzBek population from 6 to 16 years were observed (mean age 11.7 ± 0.25 years). The control group consisted of 71 healthy children of the appropriate age (mean age 11.1 ± 0.33 yea...

Background: What initiates pubertal process in humans and other mammals has remained elusive.Objective and hypotheses: We hypothesize that gene(s), whose products trigger the GnRH pulse generator to restart ticking at the usual time of puberty, can be identified via autozygosity mapping together with whole exome sequencing in patients with idiopathic hypogonadotrophic hypogonadism (IHH).Method: We studied a cohort IHH cases. Functi...

Background: Access to essential medicines remains suboptimal in Africa. The World Health Organisation (WHO) maintains two non-binding essential medicine lists (EML) (for children and for adults). Individual countries refer to these lists to prepare national EMLs.Objective and hypotheses: To determine which medicines commonly used in pediatric endocrinology and diabetes are included in the WHO and national EMLs in the WHO African region. We hypothesize th...

Background: The morphological and biochemical phenotype of Paired Box Domain Gene PAX8 mutation in patients with congenital hypothyroidism (CH) is variable. The contribution of mutations in PAX8 gene in children with CH and dysgenetic or orthotopic thyroid glands still remains a subject of interest of researchers.Objective and hypotheses: This study presents mutational analysis of the PAX8 gene in patients with primary CH.Method: 5...

Introduction: The prevalence of diabetes in Trinidad and Tobago (T&T) exceeds 12%. Monitoring of HbA1c is standard of care to assess diabetes control but assay reliability requires high precision and standardization to either DCCT or IFCC values and results should be monitored through proficiency testing (PT). In T&T a developing country there is no existing data on HbA1c precision and accuracy. Johns Hopkins Medicine International and the Diabetes Diagnostic Laborator...

Background: The contribution of mutations in paired box domain (PAX8) gene in children with congenital hypothyroidism (CH) and thyroid dysgenesis (TD) still remains a subject of interest of researchers. While quantitative PCR and direct sequencing concentrate on single gene fragment analysis and identification of point mutations, multiplex ligation-dependent probe amplification (MLPA) analysis might improve the detection rate of PAX8 mutations in patients wit...

Background: Current literature suggests an important role of both endocrine disruptors and genetic factors in the occurrence of cryptorchidism.Objective and hypotheses: The aim of the study is to investigate the impact of variants in INSL3 and HOXD13 genes in the pathogenesis of isolated cryptorchidism in Greece. 43 boys with isolated cryptorchidism and 50 healthy non-cryptorchidic boys (control group) were enrolled.<p class="abstex...

Circadian clock system is an evolutionarily conserved system, by which organisms adapt their metabolic activities to environmental inputs including nutrient availability. The master pacemaker of the clock system is located in the suprachiasmatic nucleus (SCN) in the hypothalamus. The neurons in the SCN are entrained by the signals from the light through the retinal-hypothalamic tract and the light-dark cycle of the environment creates the rhythmic patterning of behavioral and ...
