Normative Data for the Impairment Measure for Parental Food Allergy-Associated Anxiety and Coping Tool (IMPAACT) in a Canadian Sample
The Impairment Measure for Parental Food Allergy-Associated Anxiety and Coping Tool (IMPAACT) is a food-allergy anxiety questionnaire for parents of children with food allergy. While the measure has been recently validated, normative data has not yet been presented. As such, the current study provides preliminary cut-scores and percentiles to help facilitate its use as a screening tool.

The environment and food allergy
Food allergy (FA) is an immune-mediated adverse reaction to food, which has become an important global public health problem affecting up to 8% of the children and up to 5% of the adults in the USA, UK, Canada, and Australia. 1 Peanut allergy alone affects up to 1.4-4.5% of infants and young children in these countries, reaching epidemic proportions. The prevalence of food-induced anaphylaxis is presumed to have increased significantly.

A Canadian genome-wide association study and meta-analysis confirm HLA as a risk factor for peanut allergy independent of asthma
Previously, we identified the HLA region as a risk factor for peanut allergy (PA); this observation is supported further by 2 independent genome-wide association studies (GWASs).1,2 The HLA class II genes (including HLA-DR, HLA-DQ, and HLA-DP) encode molecules involved in presentation of extracellular antigens, such as peanut allergens, to T lymphocytes, which in turn mediates B-cell antibody production. We used the Canadian Peanut Allergy Registry (CanPAR) and the Busselton Health Study3 to conduct the largest GWAS for PA to date.

Canadian Physician Survey on the Medical Management of Hereditary Angioedema.
CONCLUSION: Physicians are using guidelines to support their practice, and using agents suggested by guidelines with confidence. C1-inhibitor is being used widely for prophylaxis, as well as acute treatment of attacks along with icatibant. However certain special patient populations may require additional focus in future guidelines. PMID: 29958877 [PubMed - as supplied by publisher]

Factors Associated with Increased Food Allergy-associated Anxiety in Parents of Food-allergic Children
Parents of children with food allergy can experience anxiety and difficulty coping, which can affect the child ’s ability to cope with management. Predictors of parental anxiety are currently unknown. The goal of this study was to estimate the magnitude of food allergy-associated anxiety (FAAA) in Canadian parents and determine factors associated with high anxiety.

Prevalence of physician-documented beta-lactam allergy in Canadian primary care practices
Research conducted in the U.S has determined the prevalence of reported beta-lactam allergy to be between 10-17%. Currently, there is a lack of available Canadian data on beta-lactam allergy prevalence. The purpose of this study is to describe the prevalence of physician documented beta-lactam allergies in a Canadian outpatient population and to comment on associated characteristics of patients and providers.

Economic Burden of Food Allergy in Canada: Estimating Costs and Identifying Determinants
CONCLUSION: The economic burden of FA in Canada is substantial, particularly for those with a severe reaction ever, multiple FAs, and fair/poor general health. It is crucial that those most adversely affected are allocated appropriate resources to support disease management.PMID:35500863 | DOI:10.1016/j.anai.2022.04.027
