Effect of a Hybrid Closed-Loop System on Glycemic and Psychosocial Outcomes in Children and Adolescents with Type 1 Diabetes: A Randomized Clinical TrialHybrid closed-loop (HCL) therapy has improved glycemic control in children and adolescents with type 1 diabetes; however, the efficacy of HCL on glycemic and psychosocial outcomes has not yet been established in a long-term randomized clinical trial.

Machine Learning-Based DNA Methylation Score for Fetal Exposure to Maternal SmokingFetal exposure to maternal smoking during pregnancy is associated with the development of noncommunicable diseases in the offspring. Maternal smoking may induce such long-term effects through persistent changes in the DNA methylome, which therefore hold the potential to be used as a biomarker of this early life exposure. With declining costs for measuring DNA methylation, we aimed to develop a DNA methylation score that can be used on adolescent DNA methylation data and thereby generate a score for in utero cigarette smoke exposure.

Resting Energy Expenditure and Metabolic Features in Children With Septo-Optic DysplasiaSepto-optic dysplasia (SOD) is a major cause of congenital hypopituitarism and is known to be associated with overweight and obesity in up to 44% of children. Given the role of the hypothalamus in hormonal regulation, we sought to assess the association of resting energy expenditure (REE), appetite and physical activity with SOD.

A microRNA-based dynamic risk score for type 1 diabetesIdentifying individuals at high risk of type 1 diabetes (T1D) is crucial as disease-delaying medications are available. Here we report a microRNA (miRNA)-based dynamic (responsive to the environment) risk score developed using multicenter, multiethnic and multicountry ('multicontext') cohorts for T1D risk stratification. Discovery (wet and dry lab) analysis identified 50 miRNAs associated with functional β cell loss, which is a hallmark of T1D.

Beneficial health effects of ultraviolet radiation: expert review and conference reportCarcinogenic effects of ultraviolet radiation (UVR) with reference to skin cancer are the basis of widely implemented recommendations to avoid sun exposure. Whether the benefits of "restrictive sun policies" outweigh their potential harms due to diminished beneficial effects of sunlight exposure remain a matter of controversy.

Glycemic and Psychosocial Outcomes of Advanced Hybrid Closed-Loop Therapy in Youth With High HbA1c: A Randomized Clinical TrialTo determine the efficacy of advanced hybrid closed-loop therapy in a high-risk cohort of youth on continuous subcutaneous insulin infusion with or without continuous glucose monitoring with suboptimal glycemia.

Protocol for the Australian Type 1 Diabetes National Screening Pilot: Assessing the feasibility and acceptability of three general population screening models in childrenOne third of Australian children diagnosed with type 1 diabetes present with life-threatening diabetic ketoacidosis (DKA) at diagnosis. Screening for early-stage, presymptomatic type 1 diabetes, with ongoing follow-up, can substantially reduce this risk (<5% risk). Several screening models are being trialled internationally, without consensus on the optimal approach. This pilot study aims to assess three models for a routine, population-wide screening programme in Australia.
