Abstract
PURPOSE OF REVIEW Over the past two decades, food allergy prevention strategies have shifted from 'delayed introduction' to 'no delayed introduction' to 'early introduction' of allergenic foods. This article reviews important research in this field published in the early 2020s to support future strategies for food allergy prevention. RECENT FINDINGS Recent randomized controlled trials (RCTs), systematic reviews, meta-analyses, and real-world studies have reported that early allergenic food introduction, especially peanut and egg, are effective for preventing food allergies. However, there are also reports that food-induced anaphylaxis admission rates in infants are increasing. SUMMARY Early allergenic food introduction by itself is not sufficient to prevent the development of food allergies. Recent RCTs (SPADE study and COMEET study) have demonstrated that continued regular cow's milk consumption after early introduction is important for preventing the onset of cow's milk allergy. Furthermore, an RCT (PACI study) reported that early and aggressive anti-inflammatory topical therapy for eczema can contribute to the prevention of egg allergy by suppressing percutaneous sensitization. Food allergies may be prevented through a combination of early food introduction, regular consumption, and active eczema treatment. Further research is needed to develop well tolerated, effective, and practical strategies to prevent food allergies.

Abstract
Background The incidence of allergic disease remains high, and many studies have focused on the association between food diversity in infancy and allergic disease later in life, but their conclusions are still controversial. Objective We aimed to synthesize the literature on the association between childhood diet diversity and atopic disease. Methods We searched the PubMed, Cochrane Library, Embase, Scopus, VPCS, and Wanfang databases for studies about food diversity and atopic disease. Seventeen high-quality studies, 14 cohort studies, and 1 case-control study were included from 5244 studies with sample sizes ranging from 100 to 5225. Results All high-quality cohort studies showed that increasing food diversity in infancy can effectively prevent the occurrence of food allergies (5/5). Moderate evidence showed that increased food diversity reduced the risk of asthma (4/6), food sensitization (3/5), and atopic dermatitis (3/5). However, its effect on eczema (5), allergic rhinitis (4), and other diseases remains controversial. Conclusions Increasing food diversity during infancy is a potential method for preventing food allergy, asthma, atopic dermatitis, and food sensitization later in life. There is little or no comparative evidence about the protective effect of food diversity on other atopic diseases.

Food Allergy Risk: A Comprehensive Review of Maternal Interventions for Food Allergy Prevention. Nutrients 2024; 16:1087.

Abstract
Food allergy represents a global health problem impacting patients' and caregivers' quality of life and contributing to increased healthcare costs. Efforts to identify preventive measures starting from pregnancy have recently intensified. This review aims to provide an overview of the role of maternal factors in food allergy prevention. Several studies indicate that avoiding food allergens during pregnancy does not reduce the risk of developing food allergies. International guidelines unanimously discourage avoidance diets due to potential adverse effects on essential nutrient intake and overall health for both women and children. Research on probiotics and prebiotics during pregnancy as preventive measures is promising, though evidence remains limited. Consequently, guidelines lack specific recommendations for their use in preventing food allergies. Similarly, given the absence of conclusive evidence, it is not possible to formulate definitive conclusions on the supplementation of vitamins, omega-3 fatty acids (n-3 PUFAs), and other antioxidant substances. A combination of maternal interventions, breastfeeding, and early introduction of foods to infants can reduce the risk of food allergies in the child. Further studies are needed to clarify the interaction between genetics, immunological pathways, and environmental factors.

Abstract
OBJECTIVE Shared decision-making (SDM) is increasingly used in food allergy. We review its use in the areas of prevention, diagnosis, and management. DATA SOURCES PubMed and online SDM resources. STUDY SELECTIONS Studies and reviews relevant to SDM and areas in food allergy that decision-making may be applied were selected for discussion. RESULTS Food allergy represents an area with multiple opportunities for SDM. Patients, on one hand, need to obtain the necessary information and understanding of existing options from the allergist. The allergist, on the other hand, needs to understand "where the patient is coming from," their needs, preferences, and values, so that jointly they can reach a decision that is responsive to these. Benefits of SDM include a better understanding of disease by patients, improved compliance with medication, better health outcomes, decreased health care costs, and improved ability of patients to manage their disease and make informed choices. CONCLUSION In food allergy prevention, diagnosis, and management, multiple preference-sensitive options exist for patients where SDM may be used during allergy consultations, alongside decision aids. Decision aids are tools that assist and support patients during the SDM process, by supplementing the patient-physician interaction.

Abstract
BACKGROUND Food allergy (FA) affects approximately 8% of children and may be immunoglobulin E (IgE)-mediated or non-IgE-mediated. It is recognized clinically that children with both subtypes of FA may present with features of pediatric feeding disorder (PFD); however, there is currently a limited detail of presenting characteristics. OBJECTIVE The objective of this study was to synthesize the current evidence regarding the feeding characteristics of children with FA, with a focus on the feeding skills and psychosocial domains of PFD. METHOD This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Papers published between 2001 and 2022 describing feeding characteristics in the feeding skills and psychosocial domains in children with FA/history of FA were included. Papers that focused solely on characteristics from the medical or nutritional domains were excluded. Descriptive information regarding demographics, methodology, allergy profile and history, and the characteristics of PFD observed was extracted using a preconceived data extraction form. RESULTS Overall, 40 papers contained descriptions of feeding characteristics of children with non-IgE-mediated FA (n = 22) and IgE-mediated FA (n = 11), while four were nonspecific. In the psychosocial domain, food refusal/aversion, anxiety with eating, and poor intake were the most frequently reported, regardless of FA subtype. Less information was reported regarding feeding skills, although slowness in eating, immature diet, and delays in oral sensory-motor skills were described. CONCLUSIONS Children with FA/history of FA may present with a range of characteristics that map across the feeding skill and psychosocial domains of PFD. Systematic research is needed to fully describe the feeding characteristics of children with FA. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.24562732.

Abstract
Although significant evidence exists that feeding early has a role in the prevention of food allergy, this intervention in isolation may not be sufficient. Recent evidence highlights that early introduction of peanut specifically has had no significant impact on the populational prevalence of peanut allergy. Other factors that may contribute to food allergy prevention include regularity of ingestion once an allergen is introduced and consideration to the form in which the allergen is introduced (such as baked versus cooked egg). There are also many practicalities to early feeding and some discrepant viewpoints on these practicalities, which has led to poor implementation of early feeding strategies. In general, preemptive screening before food introduction is not recommended by most international allergy societies. Although there is little guidance to inform early introduction of allergens other than milk, egg, and peanut, the mechanism of sensitization is thought to be similar and there is no harm to early introduction. In terms of frequency and duration of feeding, there is little evidence to inform any concrete recommendations.

Abstract
Early life feeding practices may affect the long-term health of individuals, particularly in terms of the development of non-communicable diseases, such as metabolic and allergic diseases. Accumulating evidence suggests that the interplay of breastfeeding and/or formula feeding followed by the introduction of solids plays a role in the occurrence of non-communicable diseases both in the short and long term. International food allergy guidelines recommend that breastfeeding women do not need to avoid food allergens and do not recommend any infant formula for allergy prevention. Guidelines regarding solid food introduction for food allergy prevention recommend the introduction of well-cooked eggs and peanuts around 4-6 months of age, and not to delay the introduction of other food allergens. There is also an increasing trend to feed infants a plant-based or plant-forward diet and have access to infant formulas based on plant-based ingredients. The use of novel plant-based infant formulas raises a few questions reviewed in this paper: (1) Do fortified, plant-based infant formulas, compliant with US Food and Drug Administration (FDA) regulations and European Food Safety Authority (EFSA) (European) guidelines, support adequate infant growth? (2) Are plant-based infant formulas suitable for the management of cow's milk allergy? (3) Does feeding with novel, plant-based infant formulas increase the risk of food allergies to the food allergens they contain? (4) Does feeding infants plant-based food allergens in early life increase the risk of allergic and severe allergic reactions? The review of the literature indicated that (1) plant-based formulas supplemented with amino acids and micronutrients to comply with FDA regulations and EFSA guidelines, evaluated in sufficiently powered growth studies, can support adequate growth in infants; (2) currently available plant-based infant formulas are suitable for the management of CMA; (3) an early introduction and continuous intake of food allergens are more likely to prevent food allergies than to increase their risk; and (4) an early introduction of food allergens in young infants is safe.

Abstract
Serum immunoglobulin E (IgE) assays to food specific IgE (s-IgE) are useful tools for the confirmation of clinical suspicion of food allergy. However, the specificity of these assays is poor given that sensitization is much more common than clinical food allergy. Therefore, the use of broad panels to assess sensitization to multiple foods often leads to overdiagnosis and unnecessary food avoidance. Unintended consequences that may occur as a result include physical harm, psychological harm, financial cost, opportunity cost, and even worsening of existing health care disparities. Although current guidelines recommend against the use of s-IgE food panel testing, these tests are widely available and frequently used. To limit the negative impacts of s-IgE food panel testing, further work is needed to effectively spread the message that these food panels may cause unintended harm to patients and families.

Abstract
The field of food allergy has seen tremendous change over the past 5-10 years with seminal studies redefining our approach to prevention and management and novel testing modalities in the horizon. Early introduction of allergenic foods is now recommended, challenging the previous paradigm of restrictive avoidance. The management of food allergy has shifted from a passive avoidance approach to active interventions that aim to provide protection from accidental exposures, decrease allergic reaction severity and improve the quality of life of food-allergic patients and their families. Additionally, novel diagnostic tools are making their way into clinical practice with the goal to reduce the need for food challenges and assist physicians in the-often complex-diagnostic process. With all the new developments and available choices for diagnosis, prevention and therapy, shared decision-making has become a key part of medical consultation, enabling patients to make the right choice for them, based on their values and preferences. Communication with patients has also become more complex over time, as patients are seeking advice online and through social media, but the information found online may be outdated, incorrect, or lacking in context. The role of the allergist has evolved to embrace all the above exciting developments and provide patients with the optimal care that fits their needs. In this review, we discuss recent developments as well as the evolution of the field of food allergy in the next decade.

Reactions to peanut at first introduction in infancy are associated with age ≥8 months and severity of eczema. Pediatr Allergy Immunol 2023; 34:ei13983. [PMID: 37366211 DOI: 10.1111/pai.13983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/29/2023] [Accepted: 06/13/2023] [Indexed: 06/28/2023]
Abstract
BACKGROUND Previous studies have shown the efficacy of the early introduction of peanut to prevent peanut allergy. Due to the exclusion of infants with sensitization to peanut, it remains unclear what the optimal timing of introduction is. METHODS The PeanutNL study was performed in 6 pediatric allergology centers in the Netherlands. Infants referred for the clinical early introduction of peanut to prevent peanut allergy underwent skin prick tests for peanut and an oral peanut challenge at a median age of 6 months. RESULTS One hundred sixty two of 707 infants (23%) who had never eaten peanut before were sensitized to peanut, of which 80 (49%) had wheals of >4 mm. Sixty seven of 707 infants (9.5%) had a positive oral challenge to peanut at first introduction. Multivariate analysis revealed that age (p < .001) and SCORAD eczema severity scores (p = .001) were significant risk factors. Introduction of peanut at ≥8 months in infants with moderate and severe eczema resulted in an increased risk (odds ratio 5.24 (p = .013) and 3.61 (p = .019), respectively) of having reactions to peanut as compared to introduction before 8 months. A family history of peanut allergy and previous reactions to egg were not identified as independent risk factors. CONCLUSION These results suggest that peanut should be introduced before the age of 8 months to reduce the risk of reactions at first exposure in infants with moderate and severe eczema. Furthermore, since children with severe eczema have the highest risk of reactions, the clinical introduction of peanut should be considered, at the latest at the age of 7 months.

Abstract
BACKGROUND Prevention guidelines have changed over the past decade and now recommend the earlier introduction of peanut and egg without delaying the introduction of other food allergens. This paper explored caregiver practices regarding the introduction of food allergens during infancy. METHODS A survey was administered (2021) to a US population-based sample of 3062 caregivers (children 7 months - 3.5 years). Demographics and feeding practices were collected. Weighted frequencies and proportions were calculated using the svyr package in R 4.1. Survey-weighted chi-square statistics and covariate-adjusted, survey-weighted logistic regression models were used for statistical inference. RESULTS Cow's milk, wheat, and soy were the top three allergens introduced. Peanut and egg were introduced by 17.2% and 15.5% of caregivers before 7 months and 58.8% and 66.4% before 1 year, respectively. The age of peanut and egg introduction differed significantly by race/ethnicity (p < .001) and caregiver age (p < .001). Peanut and egg introduction before 7 months was significantly associated with the increased introduction of other allergenic foods before 1 year (p = <.001; peanut and p = < .001; egg). Caregivers who introduced peanut and egg before 7 months infant age fed an additional mean of 5.4 and 4.5 food allergens, respectively, before 1 year. Few caregivers (0.9%) reported feeding an "early food allergen introduction product" ≥ 3 times, which was significantly associated with parental food allergy (OR = 2.2) and previously seen an allergist (OR = 6.7). CONCLUSION More than half of the caregivers are not introducing peanut by age of one year and one-third are not introducing egg, though an observed shift toward earlier peanut and egg introduction was seen in the past 5 years. Peanut and egg introduction seem to co-occur and are associated with increased intake of other food allergens.

Out-of-hospital health care costs of childhood food allergy in Australia: A population-based longitudinal study. Pediatr Allergy Immunol 2022; 33:e13883. [PMID: 36433856 PMCID: PMC9828422 DOI: 10.1111/pai.13883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 10/26/2022] [Accepted: 10/31/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Australia has one of the highest prevalence of childhood food allergy in the world, but there are no data on its economic burden in Australia. METHODS We used data from the HealthNuts study, a population-based longitudinal study undertaken in Melbourne, Australia. Infants were recruited at age 12 months between Sept 2007 and Aug 2011 with food allergy diagnosed using oral food challenges. Health care costs of out-of-hospital services were collected through data linkage to Australia's universal health insurance scheme Medicare. Two-part model was used to compare costs after controlling for potential confounders. RESULTS 2919 children were included, and 390 (13.4%) had challenge-confirmed food allergy at age 1 year. Compared with children without food allergy, children with food allergy had significantly higher costs for GP visits, specialist visits, tests, and prescriptions in the first four years of life. The total Medicare cost associated with food allergy from age 1 to 4 years was estimated to be AUD$889.7 (95% CI $566.1-$1188.3) or €411.0 (95% CI €261.5-€549.0) per child. This was projected into an annual Medicare cost of AUD$26.1 million (95% CI $20.1-$32.3 million) or €12.1 (95% CI €9.3-€14.9 million) based on population size in 2020. CONCLUSIONS Childhood food allergy causes considerable Medicare costs for out-of-hospital services in the first four years after birth in Australia. These findings can help anticipate the financial impact on the health care system associated with childhood food allergy, act as a useful costing resource for future evaluations, and inform management of childhood food allergy internationally.

Abstract
OBJECTIVE To identify a brand, key messages and resources to underpin a public health approach to food allergy prevention. METHODS A focus group design was used to explore perceptions and opinions of potential brands, infant feeding messages and resources for providing standardised food allergy prevention information. Focus groups were conducted in February 2018 using interview guides and were transcribed verbatim. A content analysis of the transcripts was undertaken using thematic analysis software. The University of Western Australia provided ethics approval: RA/4/20/4280. RESULTS Seven focus groups with 39 participants were conducted. Four slogans and styles of imagery were considered. 'Nip Allergies in the Bub' was the most favoured slogan and images of babies with food were most favoured. Participant feedback was sought regarding messages and supporting messages were considered important. Participants were consulted about useful resources and a website was identified. CONCLUSIONS Conducting focus groups assisted the selection of a brand, messages and resources to underpin a public health approach to implementing allergy prevention guidelines. IMPLICATIONS FOR PUBLIC HEALTH This is the first focus group research undertaken for food allergy prevention. Identification of a meaningful brand, key messages and resources will support a public health approach to implementing allergy prevention guidelines.

ALLERGY, ASTHMA, AND CLINICAL IMMUNOLOGY : OFFICIAL JOURNAL OF THE CANADIAN SOCIETY OF ALLERGY AND CLINICAL IMMUNOLOGY 2022; 18:36.

Abstract
Infants at high risk for developing a food allergy have either an atopic condition (such as eczema) themselves or an immediate family member with such a condition. Breastfeeding should be promoted and supported regardless of issues pertaining to food allergy prevention, but for infants whose mothers cannot or choose not to breastfeed, using a specific formula (i.e., hydrolyzed formula) is not recommended to prevent food allergies. When cow's milk protein formula has been introduced in an infant's diet, make sure that regular ingestion (as little as 10 mL daily) is maintained to prevent loss of tolerance. For high-risk infants, there is compelling evidence that introducing allergenic foods early-at around 6 months, but not before 4 months of age-can prevent common food allergies, and allergies to peanut and egg in particular. Once an allergenic food has been introduced, regular ingestion (e.g., a few times a week) is important to maintain tolerance. Common allergenic foods can be introduced without pausing for days between new foods, and the risk for a severe reaction at first exposure in infancy is extremely low. Pre-emptive in-office screening before introducing allergenic foods is not recommended. No recommendations can be made at this time about the role of maternal dietary modification during pregnancy or lactation, or about supplementing with vitamin D, omega 3, or pre- or probiotics as means to prevent food allergy.

Abstract
Purpose of Review In 2015, findings from the Learning Early About Peanut allergy (LEAP) trial provided the first convincing evidence that peanut allergy may be preventable through early peanut introduction into the infant diet. Here we discuss implementation of the LEAP study findings around the world and emerging evidence of the impacts on infant feeding and food allergy. Recent Findings The LEAP findings led to rapid changes in allergy prevention guidelines internationally to recommend early peanut introduction. There is now emerging evidence that this has been followed by a substantial increase in early peanut introduction to infants. Studies investigating the impact of these changes in infant feeding practices on the prevalence of peanut allergy are underway. Summary The LEAP trial represented a significant step forwards in food allergy prevention and new research over the past 5 years has provided insights into how best to implement this intervention in the real world.

Abstract
PURPOSE OF REVIEW This review summarizes information relating to dietary intake during pregnancy, lactation and early life that may prevent childhood asthma. This review also summarizes how future studies may be improved. RECENT FINDINGS Recent findings from observational studies suggest that eating according to certain dietary patterns during pregnancy, such as the dietary inflammatory index, Mediterranean diet and Maternal diet index, may reduce asthma and or wheeze in the child. Vitamin D supplementation with higher doses than recommended during pregnancy may be associated with reduced early transient childhood wheezing in the offspring. Higher levels of omega-3 fatty acids in breast milk may be protective against childhood asthma. Breastfeeding infants has been shown to offer many benefits to mother and child but a direct relationship between breastfeeding and the development of asthma has not been established. During childhood, infants and children may need to reduce their intake of advanced glycation end products, increase their food intake according to the traditional Mediterranean diet and increase the diversity of foods eaten. SUMMARY Current evidence provides limited suggestions regarding dietary changes for preventing early transient childhood wheezing. In order to harmonize methods for future data collection and reporting, it is important to harmonize relevant definitions and other important factors. The aim of the considerations described here is to enable a better comparison of future studies and provide better guidance to patients and families.

Abstract
Food allergy (FA) is now one of the most common chronic diseases of childhood often lasting throughout life and leading to significant worldwide healthcare burden. The precise mechanisms responsible for the development of this inflammatory condition are largely unknown; however, a multifactorial aetiology involving both environmental and genetic contributions is well accepted. A precise understanding of the pathogenesis of FA is an essential first step to developing comprehensive prevention strategies that could mitigate this epidemic. As it is frequently preceded by atopic dermatitis and can be prevented by early antigen introduction, the development of FA is likely facilitated by the improper initial presentation of antigen to the developing immune system. Primary oral exposure of antigens allowing for presentation via a well-developed mucosal immune system, rather than through a disrupted skin epidermal barrier, is essential to prevent FA. In this review, we present the data supporting the necessity of (1) an intact epidermal barrier to prevent epicutaneous antigen presentation, (2) the presence of specific commensal bacteria to maintain an intact mucosal immune system and (3) maternal/infant diet diversity, including vitamins and minerals, and appropriately timed allergenic food introduction to prevent FA.

Abstract
The Australian Feeding Infants and Toddler Study 2021 (OzFITS 2021) is a nationwide survey of Australian caregivers' infant and toddler feeding practices. Here, we describe breastfeeding rates and duration, use of breastmilk substitutes, and introduction of complementary (solid) foods, including common food allergens. Caregivers (n = 1140) were recruited by a digital marketing company and were interviewed using a structured telephone questionnaire to obtain information. Breastfeeding was initiated in 98% of infants, but the duration of exclusive breastfeeding to six months was less than 1%. Nearly 40% of children continued to receive breastmilk beyond one year, with 10% of toddlers receiving breastmilk at two years. One-quarter of infants were introduced to solid foods between 4 to 5 months, and nearly all infants had received solid foods by 7 months. New guidelines encourage the early introduction of potential food allergens to reduce the risk of allergy, and by 12 months, over 90% of children had been given eggs and peanuts. One-third of children received no breastmilk substitutes during their first year. One-third of infants first received breastmilk substitutes following birth and before discharge from the hospital. Of these infants, 30% ceased breastmilk substitute use after discharge. Our findings suggest a high rate of continued breastfeeding with 44% receiving breastmilk beyond 1 year. One approach to increase the duration of exclusive breastfeeding is to reduce breastmilk substitute use while in hospital.

Abstract
The prevalence of food allergy (FA) is increasing in some areas of the globe, highlighting the need for better strategies for prevention, diagnosis, and therapy. In the last few decades, we have made great strides in understanding the causes and mechanisms underlying FAs, prompting guideline updates. Earlier guidelines recommended avoidance of common food allergens during pregnancy and lactation and delaying the introduction of allergenic foods in children aged between 1 and 3 years. Recent guidelines for allergy prevention recommend consumption of a healthy and diverse diet without eliminating or increasing the consumption of allergenic foods during pregnancy or breast-feeding. Early introduction of allergenic foods is recommended by most guidelines for allergy prevention after a period of exclusive breast-feedng (6 months [World Health Organization] or 4 months [European Academy of Allergy and Clinical Immunology]). New diagnostics for FA have been developed with varied availability of these tests in different countries. Finally, the first oral immunotherapy drug for FA was approved by the US Food and Drug Administration and European Medicines Agency in 2020. In this review, we will address the global prevalence of FA, our current understanding of the causes of FA, and the latest guidelines for preventing, diagnosing, and treating FA. We will also discuss similarities and differences between FA guidelines.

Abstract
The incidence of allergic diseases is increasing, and research on their epidemiology, pathophysiology, and the prevention of onset is urgently needed. The onset of allergic disease begins in infancy with atopic dermatitis and food allergy and develops into allergic asthma and allergic rhinitis in childhood; the process is defined as “atopic march”. Atopic march is caused by multiple immunological pathways, including allergen exposure, environmental pollutants, skin barrier dysfunction, type 2 inflammation, and oxidative stress, which promote the progression of atopic march. Using recent evidence, herein, we explain the involvement of allergic inflammatory conditions and oxidative stress in the process of atopic march, its epidemiology, and methods for prevention of onset.

Abstract
In Korea, several national cross-sectional surveys monitor the diet, nutritional status, and health status of children. This continual dedicated national surveillance system contributes to the identification of nutritional and health issues, establishment of public health policies, and development of nutrition recommendations. This paper provides recent information about the Korea National Health and Nutrition Examination Survey and the Korean Youth Risk Behavior Web-based Survey and describes key nationwide survey findings published in the last 5 years on infant feeding practices and the dietary intake and nutritional status of Korean infants, children, and adolescents. There have been increasing trends in children, and teenagers who skip breakfast, eat fast food, consume sugary drinks, have vitamin D deficiency, and are obese. This review will inform pediatricians, nutritionists, and other health care practitioners who track children's growth and development. It may also help researchers and policymakers identify diet-related policies and strategies for chronic disease prevention in Korean infants, children, and adolescents.

Abstract
Six years ago, the Learning Early About Peanut (LEAP) trial findings helped fundamentally shift the paradigm of peanut allergy prevention. Although the results of LEAP are well accepted, policy-makers, caregivers, and clinicians struggle with how best to implement and apply the study's key findings in clinical practice. Differences in guidelines highlight issues related to peanut allergy prevention implementation, including caregiver acceptability, cost, fidelity, feasibility, appropriateness, and adoption. The goals of this rostrum are to review how the LEAP study has informed international peanut allergy prevention policy, as well as to review the strengths and ongoing controversies in peanut allergy prevention implementation.

Abstract
BACKGROUND This guideline from the European Academy of Allergy and Clinical Immunology (EAACI) recommends approaches to prevent the development of immediate-onset / IgE-mediated food allergy in infants and young children. It is an update of a 2014 EAACI guideline. METHODS The guideline was developed using the AGREE II framework and the GRADE approach. An international Task Force with representatives from 11 countries and different disciplinary and clinical backgrounds systematically reviewed research and considered expert opinion. Recommendations were created by weighing up benefits and harms, considering the certainty of evidence and examining values, preferences and resource implications. The guideline was peer-reviewed by external experts, and feedback was incorporated from public consultation. RESULTS All of the recommendations about preventing food allergy relate to infants (up to 1 year) and young children (up to 5 years), regardless of risk of allergy. There was insufficient evidence about preventing food allergy in other age groups. The EAACI Task Force suggests avoiding the use of regular cow's milk formula as supplementary feed for breastfed infants in the first week of life. The EAACI Task Force suggests introducing well-cooked, but not raw egg or uncooked pasteurized, egg into the infant diet as part of complementary feeding. In populations where there is a high prevalence of peanut allergy, the EAACI Task Force suggests introducing peanuts in an age-appropriate form as part of complementary feeding. According to the studies, it appears that the most effective age to introduce egg and peanut is from four to 6 months of life. The EAACI Task Force suggests against the following for preventing food allergy: (i) avoiding dietary food allergens during pregnancy or breastfeeding; and (ii) using soy protein formula in the first 6 months of life as a means of preventing food allergy. There is no recommendation for or against the following: use of vitamin supplements, fish oil, prebiotics, probiotics or synbiotics in pregnancy, when breastfeeding or in infancy; altering the duration of exclusive breastfeeding; and hydrolysed infant formulas, regular cow's milk-based infant formula after a week of age or use of emollients. CONCLUSIONS Key changes from the 2014 guideline include suggesting (i) the introduction of peanut and well-cooked egg as part of complementary feeding (moderate certainty of evidence) and (ii) avoiding supplementation with regular cow's milk formula in the first week of life (low certainty of evidence). There remains uncertainty in how to prevent food allergy, and further well-powered, multinational research using robust diagnostic criteria is needed.

Abstract
Given an apparent increase in food allergies worldwide, the focus on prevention strategies has intensified. Following the Learning Early About Peanut study, there is now a widespread acceptance that peanut should be introduced promptly into the diet of high-risk infants. However, most food allergies are caused by triggers other than peanut and additional prevention strategies are being evaluated. The appreciation of the role of an impaired skin barrier in the process of food sensitization and subsequent allergy has led to a spectrum of dermatologically orientated studies. Other prevention strategies address the role of the microbiome, dietary components, and other modifiable risk factors. With regard to early introduction of foods other than peanut, studies are heterogeneous in design and governmental and professional society response to the early introduction trials has varied, ranging from new guidelines confining advice specifically to peanut, to ones recommending prompt introduction of a broad spectrum of allergenic foods. Much remains to be determined with regard to the acceptability and uptake of the new guidelines and their impact on infant feeding behavior and food allergy outcomes. This review discusses the panoply of prevention approaches, their promise, and limitations.

Abstract
OBJECTIVE To prioritise and refine a set of evidence-informed statements into advice messages to promote vegetable liking in early childhood, and to determine applicability for dissemination of advice to relevant audiences. DESIGN A nominal group technique (NGT) workshop and a Delphi survey were conducted to prioritise and achieve consensus (≥70 % agreement) on thirty evidence-informed maternal (perinatal and lactation stage), infant (complementary feeding stage) and early years (family diet stage) vegetable-related advice messages. Messages were validated via triangulation analysis against the strength of evidence from an Umbrella review of strategies to increase children's vegetable liking, and gaps in advice from a Desktop review of vegetable feeding advice. SETTING Australia. PARTICIPANTS A purposeful sample of key stakeholders (NGT workshop, n 8 experts; Delphi survey, n 23 end users). RESULTS Participant consensus identified the most highly ranked priority messages associated with the strategies of: 'in-utero exposure' (perinatal and lactation, n 56 points) and 'vegetable variety' (complementary feeding, n 97 points; family diet, n 139 points). Triangulation revealed two strategies ('repeated exposure' and 'variety') and their associated advice messages suitable for policy and practice, twelve for research and four for food industry. CONCLUSIONS Supported by national and state feeding guideline documents and resources, the advice messages relating to 'repeated exposure' and 'variety' to increase vegetable liking can be communicated to families and caregivers by healthcare practitioners. The food industry provides a vehicle for advice promotion and product development. Further research, where stronger evidence is needed, could further inform strategies for policy and practice, and food industry application.

Abstract
PURPOSE OF REVIEW To summarize the impact of the COVID-19 pandemic on the practice of paediatric allergy. RECENT FINDINGS Given significant overlap in symptoms, care must be taken to differentiate routine allergic conditions from COVID-19 infection but it appears that most allergic diseases are not risk factors for a severe COVID-19 course. The full impact of restricted allergy/immunology ambulatory services will take months to years to fully understand. One benefit of having to adapt practice style is greater awareness and acceptance of shared decision-making and recognition of preference-sensitive care options in food allergy, in particular for approaches towards allergy prevention, treatment, and anaphylaxis care. Social distancing and masks have helped reduce spread of common respiratory viruses, which may be helping to lower the incidence of viral-associated wheezing episodes, enhancing evidence of the effects of preventing exposure of young children to respiratory viruses on asthma pathogenesis, as well as on allergic rhinitis. There has been a revolution in the rise of telemedicine to increase access to high-quality allergy/immunology specialty care. SUMMARY Although the field has adapted to remain operational in the face of a significant challenge, it is important to apply lessons learned to evolve patient care and optimize treatment in the aftermath of the pandemic.

Abstract
Atopic dermatitis and food allergy are the most common allergic conditions affecting the infant population. Both immunoglobulin E (IgE)-mediated and non-IgE-mediated food allergy are seen in infancy. Early life feeding guidelines have changed dramatically over the past 30 years, more recently because of an improved understanding of IgE-mediated food allergy. This article focuses on identification, diagnosis, management, and prevention of food allergy in the infant population.

Abstract
BACKGROUND Whether to screen high-risk groups before early peanut introduction is controversial. OBJECTIVE We sought to determine the risk of peanut allergy (PA) before peanut introduction for infants with (1) moderate-severe eczema, (2) another food allergy (FA), and/or (3) a first-degree relative with peanut allergy (FH). METHODS Infants aged 4 to 11 months with no history of peanut ingestion, testing, or reaction and at least 1 of the above risk factors received peanut skin prick test and, depending on skin prick test wheal size, oral food challenge or observed feeding. RESULTS A total of 321 subjects completed the enrollment visit (median age, 7.2 months; 58% males); 78 had eczema only, 11 FA only, 107 FH only, and 125 had multiple risk factors. Overall, 18% of 195 with eczema, 19% of 59 with FA, and 4% of 201 with FH had PA. Only 1% of 115 with FH and no eczema had PA. Among those with eczema, older age (odds ratio [OR], 1.3; 95% CI, 1.04-1.68 per month), higher SCORing Atopic Dermatitis score (OR, 1.19; 95% CI, 1.06-1.34 per 5 points), black (OR, 5.79; 95% CI, 1.92-17.4 compared with white), or Asian race (OR, 6.98; 95% CI, 1.92-25.44) and suspected or diagnosed other FA (OR, 3.98; 95% CI, 1.62-9.80) were associated with PA. CONCLUSIONS PA is common in infants with moderate-severe eczema, whereas FH without eczema is not a major risk factor, suggesting screening only in those with significant eczema. Even within the first year of life, introduction at later ages is associated with a higher risk of PA among those with eczema, supporting introduction of peanut as early as possible.

Ann Allergy Asthma Immunol 2021; 126:555-561.e2. [PMID: 33561539 DOI: 10.1016/j.anai.2021.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 01/21/2021] [Accepted: 02/02/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Guidelines on the early introduction of allergen-containing foods are evolving; however, little national data exist defining current allergen-feeding practices. OBJECTIVE To investigate the consumption rates of foods containing egg and peanut among infants and toddlers before the guideline changes in 2017. METHODS The Feeding Infants and Toddlers Study 2016 was conducted nationally among 3235 caregivers with a child under 4 years of age. The 24-hour dietary recalls were reviewed for peanut or egg ingredients. Participants were categorized as "consuming peanut or egg-containing foods" or "not consuming peanut or egg-containing foods." Data on physician-diagnosed food allergies and avoidance were collected. RESULTS The consumption rates of peanut- and egg-containing foods were low. For the age group of 4 to 5.9 months, 0.3% reported peanut consumption and 2.4% reported egg consumption. For the age group of 6 to 8.9 months, 0.9% reported eating peanut-containing foods and 13.0% egg, and for the age group of 9 to 11.9 months, 5.5% were consuming peanut-containing foods and 33.2% egg-containing foods. Peanut or egg ingredients were identified in the diet of children whose caregivers reported avoidance. CONCLUSION Before the publication of the 2017 Addendum Guidelines for the Prevention of Peanut Allergy, there were low rates of reported peanut consumption across the study population with less than 1% of any age group before 9 months of age and less than 6% in any age group before 12 months of age consuming peanut on the 24-hour recall day. In addition, reported egg consumption was low and increased with age. These results serve as an important baseline comparison for future studies evaluating the implementation and impact of early peanut and egg introduction.

Prevention of food allergy: can we stop the rise of IgE mediated food allergies? Curr Opin Allergy Clin Immunol 2020; 21:195-201.

Abstract
PURPOSE OF REVIEW Food allergy has become more prevalent in recent decades. Without a curative treatment for food allergy, prevention is key. Can we intervene and halt the food allergy epidemic? RECENT FINDINGS There are three main hypotheses to explain the rise in food allergy: the dual-allergen exposure hypothesis, the hygiene hypothesis and the vitamin D hypothesis. In a recent systematic review of randomized controlled trials, only introduction of allergenic foods, namely egg and peanut, in the diet at the time of weaning and avoidance of temporary supplementation with cow's milk formula in the first few days of life showed low to moderate evidence of a preventive effect. SUMMARY For primary prevention, introduction of allergenic foods at the time of weaning and avoidance of temporary supplementation with cow's milk formula in the first few days of life has been recommended. Introduction of foods once allergy has been excluded may be beneficial for sensitized subjects (secondary prevention). Once food allergy has been established, it is important to minimise complications (tertiary prevention) through allergen avoidance, timely treatment of allergic reactions, control of atopic co-morbidities and dietetic and psychological support, as appropriate. Immunomodulatory treatments can potentially be disease-modifying and require further research.

Abstract
PURPOSE OF REVIEW Introduction of peanut during the first year of life is associated with an 81% relative risk reduction of developing peanut allergy in infants with severe eczema, egg allergy, or both. However, significant international variation exists in risk stratification prior to peanut introduction. RECENT FINDINGS A policy-level screening approach, such as the one in the United States, is not practical and is associated with higher costs and more cases of peanut allergy over time, in contrast to international models that recommend universal early introduction without prescreening. In Australia, population-level efforts to introduce peanut early without screening have demonstrated high rates of peanut introduction before 12 months of age and low rates of severe allergic reactions. In contrast, screening prior to peanut introduction in the United States is associated with 'screening creep' - the tendency of clinicians to test populations where screening is not recommended. SUMMARY Early peanut introduction can reduce the risk of developing food allergy and is more effective without a risk-based screening approach. In some circumstances, shared clinical decision-making can facilitate food allergy prevention in a manner consistent with family values and preferences.

Abstract
Recently published data from high-impact randomized controlled trials indicate the strong potential of strategies to prevent the development of food allergy in high-risk individuals, but guidance in the United States at present is limited to a policy for only the prevention of peanut allergy, despite other data being available and several other countries advocating early egg and peanut introduction. Eczema is considered the highest risk factor for developing IgE-mediated food allergy, but children without risk factors still develop food allergy. To prevent peanut and/or egg allergy, both peanut and egg should be introduced around 6 months of life, but not before 4 months. Screening before introduction is not required, but may be preferred by some families. Other allergens should be introduced around this time as well. Upon introducing complementary foods, infants should be fed a diverse diet, because this may help foster prevention of food allergy. There is no protective benefit from the use of hydrolyzed formula in the first year of life against food allergy or food sensitization. Maternal exclusion of common allergens during pregnancy and/or lactation as a means to prevent food allergy is not recommended. Although exclusive breast-feeding is universally recommended for all mothers, there is no specific association between exclusive breast-feeding and the primary prevention of any specific food allergy.

Practical Challenges and Considerations for Early Introduction of Potential Food Allergens for Prevention of Food Allergy. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2020; 9:44-56.e1.

Abstract
Recent randomized controlled trials aimed at the prevention of food allergy have led to sweeping changes in food allergy prevention guidelines. Emphasis is now on the introduction of potential food allergens, particularly peanut and egg, rather than avoidance. Although guidelines recommend against delaying the introduction of other potential allergens, there remains little or no evidence of the benefit of their early introduction. Parents and physicians alike report a need for greater guidance and resources on early potential allergen introduction in the complementary feeding period. A thorough understanding of early introduction literature, current prevention guidelines, and infant nutrition will empower physicians to address patient needs and concerns both when advice is established as effective and where uncertainty remains. We discuss the state of the science, compare recommendations between guidelines, and provide practical options to introduce allergenic foods, alongside other complementary foods, within the first year of life. We include a review of the available literature, including review and suggestions of potential doses of food allergens, and the first published comparison of commercially available products and homemade early introduction foods to help clinicians support their patients. We address the nutritional, dietary, and practical considerations of introducing food allergens in the first year of life while adhering to infant feeding guidelines. Finally, given the limitations of existing guidelines, we review the need for shared decision-making between physicians and parents regarding early allergen introduction.

Abstract
AIM Introduction of allergenic solid foods, especially peanut and hen's egg reduces the risk of food allergy development in early childhood. Ideally, parents will offer their infants home-prepared foods; however, many rely on the availability of convenient ready to purchase infant foods. This audit aimed to assess the major food allergen content of commercial infant foods. METHODS Infant foods available for sale in 2019 in Australia were the focus of this audit. The major food allergens investigated were peanut, tree nuts, hen's egg, cows milk, wheat, fish, shellfish, soy, sesame and lupin. Websites of infant food manufacturers and major supermarkets were used to identify ingredient lists of infant foods available for purchase. Where ingredients listings were unavailable this information was sourced directly from the product labels in the supermarket. RESULTS Fourteen companies were identified, manufacturing over 251 foods specifically for the infants aged less than 1 year of age. Although there were many choices available containing wheat (27 products) and cows milk proteins (73 products), none contained peanut, tree nuts, sesame, shellfish or lupin. CONCLUSIONS Despite infant feeding advice encouraging early introduction to food allergens, of 251 commercial baby foods surveyed only 1% contained egg and none contained peanut, the most common food allergies in young Australian infants. This low food allergen content may be disadvantageous for infants fed mostly commercial infant foods as they are unlikely to be exposed to sufficient amounts of the major food allergens on a regular basis during infancy.

Abstract
The SARS-CoV2 pandemic has prompted a re-evaluation of our current practice of medicine. The seemingly abrupt worldwide spread of this disease resulted in immediate changes and a reduction in many allergy-focussed services and procedures. The reality of the long-term circulation of this virus in our communities requires us to evolve as a specialty. In this article, we outline current and future challenges in the management of food allergy in light of coronavirus disease 2019 (COVID-19). We focus on infant food allergy prevention, management of anaphylaxis, accurate diagnosis with oral food challenges, and active management of food allergy with oral immunotherapy. This article identifies the challenges of conflicting guidelines, shortcomings of acute management approaches, and inherent system deficiencies. We offer perspectives and strategies that can be implemented now, including an evaluation of virtual care and telemedicine for the management of food allergy. The use of a shared decision-making model results in novel approaches that can benefit our patients and our specialty for years to come. COVID-19 has forced us to re-evaluate our current way of thinking about food allergy management to better treat our patients.

Abstract
Peanut allergy is an important public health concern and causes substantial psychosocial comorbidity. Although fatal anaphylaxis is rare (occurring at 0·03-0·3 per million person-years in the general population), peanuts are one of the most frequent causes of food allergy mortality. The Learning Early About Peanut study transformed prevention of peanut allergy by showing that early introduction of peanut into the diet of children at high risk (ie, those with an egg allergy or severe eczema) reduced the relative risk of peanut allergy at age 5 years by 81%. Following publication of this study, the US National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, convened an expert panel, which recommended that, for infants with severe eczema or egg allergy, health professionals should strongly consider evaluation with peanut-specific serological IgE or skin prick test (or both) and, if necessary, an oral food challenge before peanut introduction. In the USA, depending on test results, peanut-containing foods are recommended to be introduced from age 4-6 months in infants with severe eczema or egg allergy. Early introduction to peanuts is also advocated for children with either mild to moderate or no eczema, and in children who are not allergic to egg, but without screening before peanut introduction. However, the NIAID addendum guidelines contrast with other international approaches that do not advocate for allergy screening at a population level before introducing peanuts into infants' diets. In this Review, we evaluate the advantages and disadvantages of a pre-emptive screening approach before the early introduction of peanuts in infants at high risk of peanut allergy.

Abstract
Peanut allergy is a growing public health concern in westernized countries. Peanut allergy is characterized as an often severe and lifelong allergy, which can have detrimental effects on quality of life and trigger anxiety. Although multiple therapeutic options are emerging, the focus of current management strategies is strict peanut avoidance and carriage of self-injectable epinephrine. The greatest risk of reacting to peanut comes from direct ingestion, whereas casual skin contact or airborne exposure is highly unlikely to provoke significant symptoms. Patients and families must be educated about how to best execute strict peanut avoidance through careful label reading as well as how to understand and address likely and unlikely risk with regard to peanut exposure in public, in particular when dining outside of the home and for children attending school or child care. This review discusses the risk of exposure in public such as at school or on an airplane and how such risk can be abated, situations and scenarios when dining out of the house that may pose more risks than others, the essentials of US and EU label reading laws with particular emphasis on precautionary labeling and the risk implied by such, quality of life and psychosocial issues that may affect the peanut allergic individual and family, and a discussion of how risk may differ and evolve based on the patient's age.

Abstract
OBJECTIVE Shared decision-making is a patient-centered approach that involves a mutual discussion about management or treatment options, which account for the patient's underlying values and preferences for therapy. Little is known about the role of shared decision-making in the care of patients with food allergy. DATA SOURCES A narrative review of the shared decision-making and food allergy outcomes literature in the past 20 years was performed. RESULTS In shared decision-making, care must be taken to help clarify the patient's values regarding their care options, but not instill the clinician's values or preferences into that choice. It is essential to understand the mutual roles of the clinician in the process of providing evidence-based options for care, advocating for treatments that are aligned with their goals and preferences, and allowing patients to make fully informed decisions within this paradigm. Decision support tools such as decision aids can assist patients in the values clarification process, particularly in which preference-sensitive care exists, in which options hold significant tradeoffs and varying outcomes, and the decision is reflective of personal values and preferences. There are multiple potential preference-sensitive care scenarios in food allergy in which shared decision-making could be optimized, including the development of decision aids. These areas include early allergenic solid introduction, preemptive epinephrine use in which there is allergen exposure but no symptoms, automatic activation of EMS after using epinephrine, and choices of food allergy treatment. Only one decision aid in food allergy exists. CONCLUSION Shared decision-making is an approach that could greatly enhance food allergy care and improve patient-reported outcomes.

Abstract
BACKGROUND Allergen immunotherapy (AIT) is safe and effective but is typically administered under strict clinic observation to mitigate the risk of a systemic reaction to immunotherapy (SRIT). However, in the setting of the global coronavirus disease 2019 pandemic, alternative care models should be explored. OBJECTIVE To evaluate the cost-effectiveness of home immunotherapy self-administration (HITSA) in a highly idealized circumstance for provision of maintenance AIT in a shelter-in-place or other scenarios of unforeseen reduction in nonessential medical services. METHODS Markov modeling was used to compare in-office clinic AIT in selected patients using cohort analysis and microsimulation from the societal and health care perspectives. RESULTS Assuming similar SRIT rates, HITSA was found to be a cost-effective option with an incremental cost-effectiveness ratio of $44,554/quality-adjusted life-year when considering both incremental epinephrine autoinjector costs and coronavirus disease 2019 risks. Excluding epinephrine autoinjector costs, HISTA dominated other options. However, outside of pandemic considerations, HITSA was not cost-effective (incremental cost-effectiveness ratio, $198,877,286) at annual epinephrine autoinjector costs above $287. As the incremental HITSA SRIT rate increased above 15%, clinic AIT was the most cost-effective strategy. Excluding both pandemic risks and risk of motor vehicle accident fatality from round-trip clinic transit, clinic AIT dominated other strategies. Clinic AIT was the more cost-effective option at very high fatality relative risk for HITSA or at very low annual risk of contracting coronavirus disease 2019. CONCLUSIONS Under idealized assumptions HITSA can be a safe and cost-effective option during a global pandemic in appropriately selected patients provided home rates of SRIT remain stable.

Abstract
Peanut allergy is one of the most common food allergies in children, with increasing prevalence over time. The dual-allergen exposure hypothesis now supports transcutaneous sensitization to peanut as a likely pathophysiologic mechanism for peanut allergy development. As a result, there is emerging evidence that early peanut introduction has a role in peanut allergy prevention. Current first-line diagnostic tests for peanut allergy have limited specificity, which may be enhanced with emerging tools such as component-resolved diagnostics. Although management of peanut allergy includes avoidance and carrying an epinephrine autoinjector, risk of fatal anaphylaxis is extremely low, and there is minimal risk related to cutaneous or inhalational exposure. Quality of life in children with peanut allergy requires significant focus. Moving forward, oral and epicutaneous immunotherapy are emerging and exciting tools that may have a role to play in desensitization to peanut.

Abstract
Household peanut exposure via skin in infants with impaired skin barrier function is a risk factor for peanut allergy development. The aim of this study is to investigate the peanut consumption of Koreans using national representative data. We used data from the Korean National Health and Nutrition Examination Survey 2012-2016, consisting of data from 17,625 adults who complete the survey. Peanut intake was assessed using a 24-h recall method. Of the study population, 10,552 (59.9%), 6726 (38.2%), and 347 (1.9%) subjects were categorized into non-intake, intermittent intake, and frequent intake group, respectively. Ordered logistic regression models were used to examine the association between sociodemographic and dietary factors and the frequency of peanut intake. After adjusting for confounders, increasing age (adjusted odds ratio (aOR) 1.03; 95% confidence interval (CI) 1.03-1.04), higher education (high school graduates: aOR 1.75, 95 CI 1.39-2.19; higher than college: aOR 2.11, 95% CI 1.65-2.70), and prudent dietary scores in the second (aOR 1.71; 95% CI 1.47-1.99), third (aOR 2.53; 95% CI 2.16-2.97) and the fourth quartiles (aOR 3.72; 95%CI 3.16-4.40) were associated with a high frequency of peanut consumption. This information may be helpful not only in public health research for nutrition but also in personal management for the prevention of peanut allergy in Korea.

Abstract
OBJECTIVE To define the concept of value-based care in allergy, and to review challenges and opportunities in value-based health care delivery for allergists and immunologists. DATA SOURCES Articles describing practice variation, health care financing and reimbursement, shared decision-making, cost-effective health care delivery, patient-reported outcome measures, social determinants of health, and screening. STUDY SELECTIONS A narrative review detailing concepts and approaches to improve value-based health care in the context of the Quadruple Aim to address the patient and physician experience, cost, and population health. RESULTS Efforts to improve cost-effective care can be informed by understanding unwarranted geographic practice variation and benchmarking best practices. Although evidence suggests that shared decision-making and addressing social determinants of health have critical roles in high-quality care, some practices such as routine laboratory screening for urticaria, premedication to prevent recurrent low- or iso-osmolar contrast reactions, extended observation of resolved anaphylaxis, food allergy screening, and penicillin allergy overdiagnosis have high costs in relation to overall societal benefit. Food allergy prevention, newborn screening for severe combined immune deficiency, and penicillin delabeling are examples of population-based opportunities in which allergists and immunologists can assist in creating health care value. Although efforts to incentivize value-based care have emerged in recent years, the degree to which process measures improve patient-important outcomes remain uncertain. Clinician wellness must be made a priority for continued effective practice. CONCLUSION As health care systems continue to evolve, allergists and immunologists will play a key role in optimizing value by translating emerging evidence into practice and communicating novel approaches to prevent and treat allergic diseases.

Abstract
The panorama of food allergies (FA) has changed profoundly in recent years. In light of recent advances in knowledge of pathogenetic mechanisms and a greater attention to the multifaceted range of possible clinical manifestations, there is a need for a critical review of past classifications. Changes in nutrition, environment and lifestyles around the world are modifying the global FA epidemiology and new FA phenotypes are also emerging. Furthermore, both biotechnological advances in this field and recent personalized therapies have improved the diagnostic and therapeutic approach to FA. Consequently, both the prevention and clinical management of FA are rapidly changing and new therapeutic strategies are emerging, even revolutionizing the current medical practice. Given the significant increase in the prevalence of FA in recent years, the objective of this review is to provide an updated and complete overview of current knowledge in its etiopathogenesis, diagnostics and therapy, useful not only for a better understanding of this frequent and complex pathology but also for practical guidance in its clinical management.

Abstract
BACKGROUND More than 17 million people across Europe have allergies to food and the burden of food allergies is increasing. In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published guidelines for preventing food allergy. Important research has been published since then and it is essential to ensure the guidelines reflect the latest evidence. A systematic review will be undertaken to help prepare new guidelines due to be published in 2020. METHODS Eleven bibliographic databases will be searched from inception to 31 October 2019 for randomized controlled trials about any intervention designed to prevent the development of new cases of immediate-type/IgE-mediated food allergy in infants, children and adults. There are few randomized controlled trials about the impact of breastfeeding on food allergy so prospective cohort studies about breastfeeding with at least 1000 participants at general risk or 200 at high risk of food allergy will also be eligible. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach will be used to assess the certainty of the evidence and tabulate summary data. The risk of bias in individual trials will be assessed using the Cochrane risk of bias tool. All data extraction and quality appraisal will be undertaken independently by two reviewers in partnership with a taskforce of EAACI members. CONCLUSIONS Preventing food allergy has the potential to improve personal well-being and reduce societal healthcare costs. It is important that forthcoming European guidelines take the latest research into account. Past reviews have tended to focus on single interventions or combined food allergy with other outcomes, making it difficult to draw robust conclusions about potential impacts for policy and practice.

Abstract
In the event of a global infectious pandemic, drastic measures may be needed that limit or require adjustment of ambulatory allergy services. However, no rationale for how to prioritize service shut down and patient care exists. A consensus-based ad-hoc expert panel of allergy/immunology specialists from the United States and Canada developed a service and patient prioritization schematic to temporarily triage allergy/immunology services. Recommendations and feedback were developed iteratively, using an adapted modified Delphi methodology to achieve consensus. During the ongoing pandemic while social distancing is being encouraged, most allergy/immunology care could be postponed/delayed or handled through virtual care. With the exception of many patients with primary immunodeficiency, patients on venom immunotherapy, and patients with asthma of a certain severity, there is limited need for face-to-face visits under such conditions. These suggestions are intended to help provide a logical approach to quickly adjust service to mitigate risk to both medical staff and patients. Importantly, individual community circumstances may be unique and require contextual consideration. The decision to enact any of these measures rests with the judgment of each clinician and individual health care system. Pandemics are unanticipated, and enforced social distancing/quarantining is highly unusual. This expert panel consensus document offers a prioritization rational to help guide decision making when such situations arise and an allergist/immunologist is forced to reduce services or makes the decision on his or her own to do so.
