Targeted Teacher Education to Improve Primary Preservice Teachers’ Knowledge and Understanding of UV and Effective Sun Protection Measures for ChildrenTeachers are responsible for children at school during peak ultraviolet (UV) times of the day. It is paramount that teachers have knowledge and understanding of UV to effectively protect themselves and their students. The aim of this pilot study was to investigate the effect of a short intervention on preservice teachers’ sun protective behaviours, knowledge and perceived skill to teach sun safety.

Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian adolescents and young adultsVitamin D deficiency is a public health concern worldwide. Maintaining vitamin D sufficiency during growth periods is essential. We aimed to determine the prevalence and predictors of vitamin D deficiency in Australian adolescents and young adults.

Time spent outdoors through childhood and adolescence - assessed by 25-hydroxyvitamin D concentration - and risk of myopia at 20 yearsTo investigate the relationship between time spent outdoors, at particular ages in childhood and adolescence, and myopia status in young adulthood using serum 25-hydroxyvitamin D [25(OH)D] concentration as a biomarker of time spent outdoors. Participants of the Raine Study Generation 2 cohort had 25(OH)D concentrations measured at the 6-, 14-, 17- and 20-year follow-ups. Participants underwent cycloplegic autorefraction at age 20 years, and myopia was defined as a mean spherical equivalent -0.50 dioptres or more myopic. Logistic regression was used to analyse the association between risk of myopia at age 20 years and age-specific 25(OH)D concentrations. Linear mixed-effects models were used to analyse trajectory of 25(OH)D concentrations from 6 to 20 years.

Characterising nitric oxide-mediated metabolic benefits of low-dose ultraviolet radiation in the mouse: a focus on brown adipose tissueNon-burning (low-dose) UVR suppresses the BAT 'whitening', steatotic and pro-diabetic effects of consuming a high-fat diet through skin release of nitric oxide
Research
Sun-immune connectionExposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system

Inflammatory bowel diseases: interrelationships between dietary vitamin D, exposure to UV radiation and the fecal microbiomeThis review explores the interaction of vitamin D, and ultraviolet radiation, with the intestinal innate and adaptive immune systems

The challenges of developing and optimising an assay to measure 25-hydroxyvitamin D in salivaWe have developed an LC-MS/MS assay that accurately measures saliva 25(OH)D3 levels, which correlated with serum levels

Exposure to Solar UVR Suppresses Cell-Mediated Immunization Responses in Humans: The Australian Ultraviolet Radiation and Immunity StudyHigher UVR exposure at antigen sensitization was associated with a reduced delayed-type hypersensitivity response and altered T helper type 17 kinetics
Research
Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humansThe proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans
Research
Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in miceSkin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted
