Vitamin D has been recognized to have a significant impact on modulating immune response in the host body. The relationship between deficiency of Vitamin D and rectovaginal colonization with Group B Streptococcus (GBS) in pregnant women is still not well understood.
Carcinogenic 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.
The colonisation of Australia around 250 years ago left a significant enduring impact on the mental health of Aboriginal and Torres Strait Islander peoples. Vitamin D may play a role in modulating mental health as its receptors are present in the brain regions associated with mood and behaviour regulation.
In a sunny country such as Australia, it’s important to identify how to achieve the right amount of sun exposure for good health. We need to be able to harness the benefits of vitamin D and sunlight while remaining protected from the proven dangers of too much UV radiation.
We developed the iOS smartphone app Sun Safe to support healthy sun practices in young teenagers (aged 12-13 years). The production involved co-design with young co-researchers (ie, aged 12-13 years) with a health message of using sun protection when the UV index is ≥3. Important features include real-time and location-specific weather data on the UV index and gamified educational content.
The developmental origins of handedness remain elusive, though very early emergence suggests individual differences manifesting in utero could play an important role. Prenatal testosterone and Vitamin D exposure are considered, yet findings and interpretations remain equivocal.
Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.
This review focuses primarily on the beneficial effects for human health of exposure to ultraviolet radiation
New initiatives to develop a standard reference method and the assignment of "true" values to samples provide a solution to these problems.
