BACKGROUND Several indicators suggest that food allergy in infants is common and possibly increasing. Few studies have used oral food challenge to measure this phenomenon at the population level. OBJECTIVE To measure the prevalence of common IgE-mediated childhood food allergies in a population-based sample of 12-month-old infants by using predetermined(More)
UNLABELLED The evidence that mutations in the HFE gene for hemochromatosis are associated with increased cancer risk is inconsistent. The Melbourne Collaborative Cohort Study is a prospective cohort study that commenced recruitment in 1990. Participants born in Australia, New Zealand, the United Kingdom, or Ireland (n = 28,509) were genotyped for the HFE(More)
There is emerging evidence that there are genetic modifiers of iron indices for HFE gene mutation carriers at risk of hereditary hemochromatosis. A random sample, stratified by HFE genotype, of 863 from a cohort of 31 192 people of northern European descent provided blood samples for genotyping of 476 single nucleotide polymorphisms (SNPs) in 44 genes(More)
Lyngbya majuscula is a benthic filamentous marine cyanobacterium, which in recent years appears to have been increasing in frequency and size of blooms in Moreton Bay, Queensland. It has a worldwide distribution throughout the tropics and subtropics in water to 30m. It has been found to contain a variety of chemicals that exert a range of biological(More)
A survey of residents in an area subject to annual toxic cyanobacterial blooms was undertaken to examine potential health effects of cyanobacteria toxins. The survey assessed the health of marine recreational water users in Deception Bay/Bribie Island area in northern Moreton Bay, Queensland, which is exposed to blooms of the nuisance and potentially(More)
BACKGROUND The evidence on whether the atopic march observed in childhood (ie, the progression from eczema to allergic rhinitis and asthma) extends to adulthood is sparse, and there is no evidence on whether the progression leads to a specific phenotype of asthma. OBJECTIVE We sought to assess whether childhood eczema and rhinitis are risk factors for(More)
OBJECTIVES The aims of this study were to estimate the prevalence of Ménière's disease and investigate its relationship with: demographic factors; symptoms and conditions that are known or hypothesized to be associated with Ménière's disease; other physical diseases; mental health. DESIGN The authors used cross-sectional data from the UK Biobank to(More)
BACKGROUND Infant feeding guidelines have long recommended delaying introduction of solids and allergenic foods to prevent allergy in high-risk infants, despite a paucity of evidence. OBJECTIVE We aimed to determine whether confirmed egg allergy in 12-month-old infants is associated with (1) duration of breast-feeding and (2) ages of introducing egg and(More)
BACKGROUND & AIMS There are few longitudinal studies of serum ferritin (SF) and transferrin saturation (TS) levels in individuals homozygous for the C282Y mutation. We characterized the development of elevated iron measures in C282Y homozygotes followed for 12 years. METHODS From 31,192 people aged 40-69 years at baseline, we identified 203 C282Y(More)
BACKGROUND The endocrine-disrupting chemical bisphenol A (BPA) is widely used in food and beverage packaging. Higher urinary BPA concentrations were cross-sectionally associated with heart disease in National Health and Nutrition Examination Survey (NHANES) 2003-2004 and NHANES 2005-2006, independent of traditional risk factors. METHODS AND RESULTS We(More)
