Prevalence and Sociodemographic Variation of Allergic Diseases in Australia: Findings From the Australian National Health Survey

The prevalence of allergic diseases across the Australian population, in all regions and age groups, is not well documented. This study aimed to describe the prevalence and distribution of five allergic diseases (allergic rhinitis, asthma, drug allergy, eczema, and food allergy) and examine differences by sociodemographic factors. 

Body mass index, prebiotic supplementation during pregnancy and gestational diabetes mellitus risk: an effect modification analysis from a randomised controlled trial

Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus

An Old Story Back: Human Milk Antibodies' Protective Roles Against Allergy Development

Human milk is a rich source of immunomodulatory factors that influence the development of the infant immune system, including susceptibility to allergic diseases. Among these components, milk antibodies have been extensively studied for their role in protecting against infections; however, their potential contribution to allergy prevention may be equally important. The mechanisms of protection include allergen exclusion, enhanced and targeted antigen presentation, immune modulation via shaping of the infant gut microbiome, and direct regulation of gut immune responses.

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.

Longitudinal egg-specific regulatory T- and B-cell development: Insights from primary prevention clinical trials examining the timing of egg introduction

Egg allergy affects almost 1 in 10 Australian infants. Early egg introduction has been associated with a reduced risk in developing egg allergy; however, the immune mechanisms underlying this protection remain unclear.

High-Fiber Diet during Pregnancy Characterized by More Fruit and Vegetable ConsumptionHigh-Fiber Diet during Pregnancy Characterized by More Fruit and Vegetable Consumption

Higher dietary fiber intakes during pregnancy may have the potential health benefits of increasing gut microbiome diversity, lowering the risk of glucose intolerance and pre-eclampsia, achieving appropriate gestational weight gain, and preventing constipation. In this observational cohort study, we have assessed the dietary fiber intakes of 804 women in late pregnancy, using a semi-quantitative food frequency questionnaire (SQ-FFQ). Overall, the median (interquartile range) dietary fiber intake was 24.1 (19.0-29.7) grams per day (g/day). Only 237/804 (29.5%) women met the recommended Adequate Intake (AI) of dietary fiber during pregnancy of 28 g/day.

Study protocol for a randomised controlled trial evaluating the effect of folic acid supplementation beyond the first trimester on maternal plasma unmetabolised folic acid in late gestation

Taking folic acid containing supplements prior to and during early pregnancy reduces the risk of neural tube defects. Neural tube defects occur prior to 28 days postconception, after which, there is no proven benefit of continuing to take folic acid. However, many women continue to take folic acid containing supplements throughout the pregnancy.

Ovalbumin in breast milk is associated with a decreased risk of IgE-mediated egg allergy in children

Showed for the first time that the presence of an egg-derived allergen in breast milk is associated with a reduced risk of egg allergy in children at 2.5 years of age

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
