Higher ultraviolet radiation during early life is associated with lower risk of childhood type 1 diabetes among boys

Population-level ecological studies show type 1 diabetes incidence is inversely correlated with ambient ultraviolet radiation (UVR) levels. We conducted a nested case–control study using administrative datasets to test this association at the individual level.

Investigating associations between birth order and autism diagnostic phenotypes

Birth order effects have been linked to variability in intelligence, educational attainment and sexual orientation. First- and later-born children have been linked to an increased likelihood of an Autism Spectrum Disorder (ASD) diagnosis, with a smaller body of evidence implicating decreases in cognitive functioning with increased birth order.

Additional Insulin Is Required in Both the Early and Late Postprandial Periods for Meals High in Protein and Fat: A Randomized Trial

The pattern and quantity of insulin required for high-protein high-fat (HPHF) meals is not well understood. This study aimed to determine the amount and delivery pattern of insulin required to maintain euglycemia for 5 hours after consuming a HPHF meal compared with a low-protein low-fat (LPLF) meal.

Type 1 diabetes in pregnancy is associated with distinct changes in the composition and function of the gut microbiome

The gut microbiome changes in response to a range of environmental conditions, life events and disease states. Pregnancy is a natural life event that involves major physiological adaptation yet studies of the microbiome in pregnancy are limited and their findings inconsistent. Pregnancy with type 1 diabetes (T1D) is associated with increased maternal and fetal risks but the gut microbiome in this context has not been characterized. By whole metagenome sequencing, we defined the taxonomic composition and function of the gut bacterial microbiome across 70 pregnancies, 36 in women with T1D.

Meal-time glycaemia in adults with type 1 diabetes using multiple daily injections vs insulin pump therapy following carbohydrate-counting education and bolus calculator provision

To compare meal-time glycaemia in adults with type 1 diabetes mellitus managed with multiple daily injections vs. insulin pump therapy, using self-monitoring blood glucose, following diabetes education.

Small-area geographical variation in the prevalence of diabetes amongst Australian youth aged <20 years in 2021

To characterise small-area geographical variation in the prevalence of diabetes in Australian youth. A combined statistical reconstruction and small-area estimation algorithm was applied to privacy-modulated data from the 2021 Australian Census. 

SARS-CoV-2 Infection and Childhood Islet Autoimmunity

This cohort study examines whether there is a temporal association between SARS-CoV-2 infection and the development of islet autoimmunity among Australian children with a first-degree relative with type 1 diabetes.  

Resting Energy Expenditure and Metabolic Features in Children With Septo-Optic Dysplasia

Septo-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. 

Short-Term Diabetic Retinopathy Status in People with Type 1 Diabetes Commencing Automated Insulin Delivery

Rapid improvements in glucose control may lead to early worsening of diabetic retinopathy (EWDR). There is a need to demonstrate safety in people commencing automated insulin delivery (AID) due to the known efficacy in rapid glycemic improvement. We aimed to investigate short-term DR outcomes in people (aged ≥13 years) with type 1 diabetes after initiation of AID (use ≥6 months).

X-Linked Hypophosphataemia and Burosumab: A Systemic Disease With a New Treatment

X linked hypophosphataemia (XLH) is a systemic, chronic condition that significantly impairs quality of life. In XLH, a phosphate regulating endopeptidase homologue X-linked (PHEX) gene mutation leads to excess fibroblast growth factor 23 (FGF23), causing hypophosphataemia and subsequent rickets, lower limb deformity, pain and other sequelae, however there are likely other non-FGF23 mediated mechanisms contributing to disease
