Children with Brain Tumors have Enhanced Visceral Adiposity Compared to Non-Cancer Controls: A Preliminary Analysis from the Canadian Study of Determinants of Endometabolic Health in Children Study

Wang Kuan-Wen , Fleming Adam , Burrow Sarah , de Souza Russell J. , Thabane Lehana , Samaan M. Constantine

Background: Survivors of childhood brain tumors (SCBT) are an emerging group that have premature mortality and morbidities that can negatively impact their quality of life and lifespan. Cardiovascular disease, obesity and diabetes are important causes of premature mortality in survivors, yet one of the major determinants of cardiometabolic risk i.e. visceral adiposity has not been determined in this group.Objective and hypotheses: This study is comparing...

Impact of GH on Adult Bone Quality in Turner Syndrome: a High Resolution Peripheral Quantitative Computed Tomography Study

Nour Munier A , Perry Rebecca J , Stephure David K , Hanley David A , Boyd Steven K

Background: Women with Turner syndrome (TS) are known to be at risk of osteoporosis and fracture. While childhood GH treatment is common in TS, the impact of this therapy on bone health has been poorly understood.Objective: The purpose of this study was to determine the effect of childhood GH-treatment on adult bone quality in TS women using dual X-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HR-pQCT).<p c...

A Novel Missense Variant in the Insulin Receptor Gene in Three Unrelated Irish Families with Severe Insulin Resistance Syndrome: Evidence for an Irish Founder Effect

Mavinkurve M , O'Connell S , Cody D , Isaac I , Harris J , Semple R K , Mc Donnell C

Background: Genetic defects in the insulin receptor (INSR) are rare. Precise prevalence is unknown and significant clinical heterogeneity exists. Over 120 allelic variants have been described to date, spread throughout the receptor, and few geographical founder effects have been described. In this case series we identify a novel missense mutation in the tyrosine kinase domain of the INSR in three independently ascertained Irish families.Objective and Hyp...

Overexpression of Supressor Tumoral PTEN, but not DREAM, was Detected in Multinodular Goiter in Humans

Shinzato Amanda , Lerario Antonio M , Danilovic Debora S , Marui Suemi , Lin Chin J , Trarbach Ericka B

Background: A high proliferative status of thyroid follicular cells and goiter were observed in mutants mice with Pten−/− or Dream overexpression. In humans, patients with Cowden disease have goiters or other thyroid abnormalities associated with germ-line PTEN mutations.Objective and Hypotheses: The aim of this study was to investigate the tissue expression of PTEN and DREAM, as well as germ-line ...

Pro-Inflammatory (M1) and Anti-Inflammatory (M2) Profiles in Adipose Tissue of Lean and Obese Children and Adolescents

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Childhood obesity predisposes to metabolic disorders. Low grade inflammation of adipose tissue (AT) associated with macrophage infiltration may lead to metabolic complications. Two macrophage activation states M1 (pro-inflammatory) and M2 (anti-inflammatory) exist in AT with surface markers CD40 (M1), CD206 (M2) and CD163 (M2). M1 polarization correlates with metabolic complications.Objective and hypotheses: To study the expression of CD40, C...

Impact of Maternal and Fetal Inflammatory Markers on Neonatal and Infant Adiposity

Donnelly Jean M , Walsh Jennifer M , Horan Mary , Molloy Eleanor J , Auliffe Fionnuala Mc

Background: The effect of maternal obesity and the associated maternal inflammation on neonatal and paediatric health and wellbeing over the early childhood years is not fully understood.Objective and hypotheses: This study aimed to determine the impact of maternal and fetal inflammatory factors on infant anthropometric measurements.Method: 265 mother–infant pairs from an RCT assessing the effect of a low glycaemic index diet ...

Genome-Wide Promoter Methylation Analysis in Cytologically Indeterminate Thyroid Nodules

Trarbach Ericka B , Shinzato Amanda , Lin Chin J , Marui Suemi , Lerario Antonio M

Background: Differentiating potentially malignant thyroid nodules among those undetermined by cytology avoid unnecessary surgical procedures. Aberrant DNA methylation is ubiquitous in human cancers, including thyroid tumors. Biomarkers based on methylation profiles have been successfully used to diagnose early stage malignancy in many human cancers.Objective and hypotheses: To determine the genome-wide promoter methylation status of cytologically indeter...

Novel Uncoupling Protein 1 Expression in White Adipocytes of Subcutaneous Abdominal Adipose Tissue in Children and Adolescents: A Protective Mechanism for Metabolic Equilibrium?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...

Early Occurrence of Gonadoblastoma Found at Elective Gonadectomy in Turner Syndrome Mosaic for Y Chromosome

MacMahon J , Morrissey R , McDermott M , O'Sullivan M , Quinn F , Green A , Lynch S A , O'Connell S M

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...

A Child with Clinical and Cytogenetic Features of Male Edward Syndrome and Turner Syndrome with Bilateral Gonadoblastoma in Infancy

MacMahon J , Morrissey R , McDermott M , Quinn F , Green A , Lynch SM

Background: Mosaic Turner syndrome (TSM) commonly occurs in the form of 45,X/46,XX and 45,X/46,Xiq, although mosaicism including the presence of a Y chromosome has been well documented. It is associated with increased risk of gonadoblastoma (GB).Objective and hypotheses: To date, there are only six reported cases of TSM with a trisomy 18 karyotype, and only two of these were phenotypically female with 45,X, 47,XY+18 karyotype.Metho...
