Low serum 25-hydroxyvitamin D concentrations associate with non-alcoholic fatty liver disease in adolescents independent of adiposity

This paper examined the link between low serum Vitamin D levels and development of non-alcoholic fatty liver disease (NAFLD) in adolescents between 14 and 17...

Vitamin D status and ill health

This paper is a comment in response to a review of Vitamin D status and its association with ill health.

Environmental, personal, and genetic determinants of response to vitamin D supplementation in older adults

We aimed to examine genetic and nongenetic determinants of change in serum 25-hydroxyvitamin D (25(OH)D) after supplementation.

What is the optimal level of vitamin D?: Separating the evidence from the rhetoric

New evidence indicates that both high and low 25(OH)D levels may be associated with increased health risks.

Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans

The 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

Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in mice

Skin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted

Cellular and molecular mechanisms of vitamin D in food allergy

Epidemiological evidence from the past decade suggests a role of vitamin D in food allergy pathogenesis

Vitamin D is crucial for maternal care and offspring social behaviour in rats

These data highlight that early life levels of vitamin D are an important consideration for maternal behavioural adaptations as well as offspring neuropsychiatry

A Gender Lens on User Quality Ratings From Young Teenagers Assessing the Sun Safe App: Comparing Responses From Co-researchers and Participants of Pilot Intervention Studies

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.

A longitudinal examination of perinatal testosterone, estradiol and vitamin D as predictors of handedness outcomes in childhood and adolescence

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.
