Abstract
BACKGROUND Major fish allergens, including parvalbumin (PV), are heat stable and can withstand extensive cooking processes. Thus, the management of fish allergy generally relies on complete avoidance. Fish-allergic patients may be advised to consume canned fish, as some fish-allergic individuals have reported tolerance to canned fish. However, the safety of consuming canned fish has not been evaluated with comprehensive immunological and molecular analysis of canned fish products. METHODS We characterized the in vitro immunoreactivity of serum obtained from fish-allergic subjects to canned fish. Seventeen canned fish products (salmon n = 8; tuna n = 7; sardine n = 2) were assessed for the content and integrity of PV using allergen-specific antibodies. Subsequently, the sIgE binding of five selected products was evaluated for individual fish-allergic patients (n = 53). Finally, sIgE-binding proteins were identified by mass spectrometry. RESULTS The canned fish showed a markedly reduced PV content and binding to PV-specific antibodies compared with conventionally cooked fish. However, PV and other heat-stable fish allergens, including tropomyosin and collagen, still maintained their sIgE-binding capacity. Of 53 patients, 66% showed sIgE binding to canned fish proteins. The canned sardine contained proteins bound to sIgE from 51% of patients, followed by canned salmon (43%-45%) and tuna (8%-17%). PV was the major allergen in canned salmon and sardine. Tropomyosin and/or collagen also showed sIgE binding. CONCLUSION We showed that canned fish products may not be safe for all fish-allergic patients. Canned fish products should only be considered into the diet of individuals with fish allergy, after detailed evaluation which may include in vitro diagnostics to various heat-stable fish allergens and food challenge conducted in suitable environments.

Abstract
BACKGROUND This article introduces the concept, food allergy literacy (FAL), which encompasses the knowledge, behaviors, and skills needed to manage a food allergy and is thus critical to child safety. Yet, there is limited clarity on how to promote FAL in children. METHODS Twelve academic databases were systematically searched to identify publications on interventions to promote FAL in children. Five publications met the inclusion criteria, which involved children (3 to 12 years), their parents, or educators and tested the efficacy of an intervention. FINDINGS Four interventions were for parents and educators, while 1 intervention was for parents with their children. The interventions were educational and focused on promoting participant knowledge and skills of food allergy, and/or psychosocial in nature, promoting coping, confidence, and self-efficacy in managing children's allergies. All interventions were deemed effective. Only 1 study used a control group, and none assessed the long-term benefits of the interventions. IMPLICATIONS FOR SCHOOL POLICY, PRACTICE, AND EQUITY The results can enable health service providers and educators to design evidence-based interventions to promote FAL. This might involve designing, implementing, and evaluating curricula and play-based activities, therein, that award greater attention to food allergy-its consequences, risks, skills to prevent risk, and managing food allergy in educational settings. CONCLUSIONS There is limited evidence on child-focused interventions that promote FAL. There is, therefore, considerable opportunity to co-design and test interventions with children.

Abstract
Food allergy is a chronic disease that affects individuals of all ages and is a significant public health problem globally. This narrative overview examines clinical management strategies for IgE-mediated food allergy in children around the world to understand variations in practice. Information was drawn from clinical practice guidelines, recent research, the websites of professional and governmental bodies with expertise in food allergy, and clinical experts from a broad cross-section of geographical regions. The structure and delivery of clinical services, allergen avoidance and food labeling, and resources to support the management of allergic reactions in the community are discussed in detail. The adoption of emerging food immunotherapies is also explored. Wide variations in clinical management of food allergy were apparent across the different countries. Common themes were continuing issues with access to specialist care and recognition of the need to balance risk reduction with dietary and social restrictions to avoid unnecessary detrimental impacts on the quality of life of food allergy sufferers. Findings highlight the need for standardized presentation of practice and priorities, and may assist clinicians and researchers when engaging with government and funding agencies to address gaps.

Abstract
Food allergy (FA) affects 8% of US children. Navigating and managing FA permeates across multiple facets of childhood. In this article, we review research on social disparities in feeding practices, managing meals, and selecting childcare and schools. Key highlights include the following: (1) although preference for breast-feeding or formula feeding does not reduce FA risk, there are disparities in access to formula that may affect children with FA; (2) disparities likely exist in the early introduction to allergenic foods, though additional research is needed to identify barriers to following the most recent consensus guidelines on early introduction; (3) families with limited income face challenges in providing safe meals for their children; (4) disparities exist in early childcare options for preschool-age children, though there is a lack of research on FA practices in these settings; and (5) there is evidence that schools with different student demographics implement different types of FA policies. Further research is needed to better understand and characterize social disparities in FA prevention and management in early childhood and to develop evidence-based strategies to reduce them.

Abstract
Food allergy prevalence in the United States has been increasing among school-aged children. Many community-based pediatric caregivers (e.g., camp staff, sports coaches) are not trained to prevent, recognize, or manage allergic reactions due to a lack of available training and standard policies on this topic. Epinephrine is the first-line of treatment for severe allergic reactions and delayed administration of this medication can result in poor health outcomes and death. School nurses may use their knowledge and expertise to educate community-based pediatric caregivers on allergy topics. Professional practice projects can be utilized by school nurses to help improve allergy and anaphylaxis confidence and knowledge among community-based pediatric caregivers. By educating community members on anaphylaxis management, it can improve health outcomes for children of the school community and result in saved lives.

Abstract
A food allergy is an immunoglobulin E (IgE)-mediated hypersensitive reaction to food, which consists in the appearance of allergic symptoms; it can vary from common urticaria to even fatal anaphylaxis. The prevalence of food allergies has been increasing in the past twenty years and it represents a major public health problem in industrialized countries. The mechanism that leads to food allergies is the lack of immunologic and clinical tolerance to food allergens. The diagnosis of IgE-mediated food allergies is based on the combined use of a detailed medical history, in-vivo, and in-vitro research of specific IgE, the elimination diet, and the double-blind placebo-controlled food challenge. The only currently available treatment for allergies is the strict elimination diet. This type of attitude, which we could define as “passive”, does not overcome the risk of accidental reactions due to involuntary intake of the culprit food. For food allergy management, an “active” approach is urgently needed, such as specific allergen immunotherapy, which is currently under development and only used for research purposes. This article aims to give an updated review of IgE-mediated food allergies in pediatric populations in terms of epidemiology, pathogenesis, prevention, diagnosis, and management.

Abstract
BACKGROUND Families with food allergy (FA) are at risk of reduced quality of life and elevated anxiety. A moderate level of anxiety may be beneficial to sustain vigilance for food avoidance; however, excessive anxiety may increase risk for burden and maladjustment. The current study presents a framework for understanding the patterns of adaptation to FA across families and to identify typologies of families that would benefit from intervention. METHODS Participants included 57 children, 6-12 years old with documented FA, and their mothers. Families were assessed using the Food Allergy Management and Adaptation Scale. Families also completed measures of quality of life, anxiety, FA management, and psychosocial impairment. RESULTS A hierarchical cluster analysis revealed that 56 of the 57 families of food-allergic children were categorized into four groups that differed on their adequacy of family FA management, levels of anxiety, and balanced psychosocial functioning: balanced responders (n = 23; 41%), high responders (n = 25; 45%), and low responders (n = 3; 5%). The fourth group, anxious high responders (n = 5; 9%), was characterized by extremely high maternal FA anxiety scores and low scores for balanced integration of FA management and psychosocial functioning. Families in clusters differed across illness and psychosocial outcome variables. CONCLUSION Families with FA were characterized by patterns of FA management, anxiety, and ability to integrate FA demands into daily life. Identified adaptation patterns correspond with clinical impressions and provide a framework for identifying families in need of intervention.
