A role for early oral exposure to house dust mite allergens through breast milk in IgE-mediated food allergy susceptibility

This study highlights an unpredicted potential risk factor for the development of food allergy, that is, D pteronyssinus allergens in breast milk

The challenges of developing and optimising an assay to measure 25-hydroxyvitamin D in saliva

We have developed an LC-MS/MS assay that accurately measures saliva 25(OH)D3 levels, which correlated with serum levels

Maternal Fiber Dietary Intakes during Pregnancy and Infant Allergic Disease

Maternal resistant starch consumption was differentially associated with infant phenotypes, with reduced risk of infant wheeze, but increased risk of eczema

Prebiotics: mechanisms and preventive effects in allergy

In this review, we describe both the mechanisms and the therapeutic evidence from preclinical and clinical studies exploring the role of prebiotics in allergy prevention

Direct infant UV light exposure is associated with eczema and immune development

This study is the first to demonstrate an association between greater direct UV light exposures in early infancy with lower incidence of eczema

Prenatal omega-3 LCPUFA and symptoms of allergic disease and sensitization throughout early childhood

Maternal supplementation with 900 mg of ω-3 LCPUFA did not change the progression of IgE-mediated allergic disease symptoms or sensitization

Taking a prebiotic approach to early immunomodulation for allergy prevention

In this review we examine maternal and infant dietary sources of prebiotics with a particular focus on non-digestible oligosaccharides, which undergo SCFA.

Fecal sample collection methods and time of day impact microbiome composition and short chain fatty acid concentrations

Associations between the human gut microbiome and health outcomes continues to be of great interest, although fecal sample collection methods which impact microbiome studies are sometimes neglected. Here, we expand on previous work in sample optimization, to promote high quality microbiome data. To compare fecal sample collection methods, amplicons from the bacterial 16S rRNA gene (V4) and fungal (ITS2) region, as well as short chain fatty acid (SCFA) concentrations were determined in fecal material over three timepoints.

The influence of sunlight exposure and sun protecting behaviours on allergic outcomes in early childhood

The dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.
