10.11. Childhood-onset type 1 diabetes and subsequent adult psychiatric disorders: a nationwide cohort and genome-wide Mendelian randomization study

T Formanek , D Chen , Z Šumnik , K Mlada , J Hughes , S Burgess , al. et

Brief Summary: This study explored the potential causal pathways underlying the association between childhood-onset T1D and subsequent psychiatric disorders, using data from a Czech national register of 4,500 children (age ≤14 years) with type 1 diabetes (T1D) and large-scale European genetic studies. Children diagnosed with T1D had an elevated risk of developing substance use, mood, anxiety and personality disorders, and behavioural syndromes. In contrast, they had a lo...

Brief summary: This study evaluated the ability of genetic risk scores to predict severe obesity in adult survivors of childhood cancer. Data from 2548 survivors of European ancestry from the St. Jude Lifetime Cohort Study was analyzed and findings were validated in 6064 survivors from the Childhood Cancer Survivor Study. Survivors with higher genetic risk scores had significantly higher odds of severe obesity. Adding genetic risk scores to prediction models that included canc...

2.10. Leptin and adiposity measures from birth to later childhood: Findings from the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) Follow-Up Study

S DeLacey , M Gurra , J Arzu , LP Lowe , WL Lowe , DM Scholtens , JL Josefson

Brief Summary: This study was based on the HAPO prospective birth cohort, which has previously generated several publications on maternal gestational diabetes in relation to neonatal anthropometry and childhood glucose metabolism1,2. It examined if cord blood leptin was positively associated with peripubertal obesity and adiposity, and if this relationship was dependent on maternal BMI, hyperglycemia and/or other maternal factors.This is an im...

10.14. RANKL/RANK is required for cytokine-induced beta cell death; osteoprotegerin, a RANKL inhibitor, reverses rodent type 1 diabetes

NG Kondegowda , J Filipowska , JS Do , N Leon-Rivera , R Li , R Hampton , al. et

Brief Summary: Through a series of experiments in the nonobese diabetic/Ltj mouse model and human β-cells, the authors show that the RANK pathway mediates cytokine-induced β-cell death through RANK-TRAF6 interaction and induction of NF-KB activation. Inhibition of the RANKL/RANK pathway following treatment with osteoprotegerin and denosumab protected β-cells against this cytotoxicity, reduced proinflammatory cytokines in activated T-cells, and reversed T1D in th...
