Food allergies (FA) and asthma commonly coexist in patients, with asthma affecting 14% of school-age children and with FA affecting up to 8% of children in the United States. Compared with children without FA, children with FA are two to four times more likely to have asthma. The timings of food sensitization and FA seem to be strong predictors of asthma onset in childhood; results of studies show that food sensitization in the first few years of life is associated with increased odds of developing early wheeze. Having multiple FAs as opposed to a single FA further compounds the risk of asthma. Reciprocally, there is a strong association between the presence of food sensitization and/or FA and poor asthma control, including increased asthma-related health-care utilization and emergency medication use. Asthma is a risk factor in ∼75% of fatal food-related anaphylaxis cases. Therefore, besides FA education and management, patients with FA and with asthma should optimize medical therapy of their asthma and receive asthma education, including identifying possible asthma triggers. Furthermore, allergists should ensure that asthma must be well controlled before conducting oral food challenges. Timely administration of epinephrine is lifesaving and remains the first-line treatment during food-induced anaphylaxis, especially in patients with asthma. Among those biologic therapies that have been highly effective in treating asthma, omalizumab and dupilumab are now also being studied as treatments for FA.

Food Challenges

A verified food allergy can be an impactful life event that leads to increased anxiety and measurable effects on quality of life. Allergists play a key role in framing this discussion and can help alleviate underlying fears by promoting confidence and clarifying safety concerns. Correctly diagnosing a patient with an immunoglobulin E (IgE) mediated food allergy remains a nuanced process fraught with the potential for error and confusion. This is especially true in situations in which the clinical history is not classic, and allergists rely too heavily on food allergy testing to provide a confirmatory diagnosis. A comprehensive medical history is critical in the diagnosis of food allergy and should be used to determine subsequent testing and interpretation of the results. Oral food challenge (OFC) is a critical procedure to identify patients with an IgE-mediated food allergy when the history and testing are not specific enough to confirm the diagnosis and can be a powerful teaching tool regardless of outcome. Although the safety and feasibility of performing OFC in a busy allergy office have always been a concern, in the hands of an experienced and trained provider, OFC is a safe and reliable procedure for patients of any age. With food allergy rates increasing and analysis of recent data that suggests that allergists across the United States are not providing this resource consistently to their patients, more emphasis needs to be placed on food challenge education and hands-on experience. The demand for OFCs will only continue to increase, especially with the growing popularity of oral immunotherapy programs; therefore, it is essential that allergists become familiar with the merits and limitations of current testing modalities and open their doors to using OFCs in the office.

The Cost

Introduction. Food allergies affect 8% of the pediatric population in the United States with an estimated annual cost of US$25 billion. The low specificity of some of the main food allergy tests used in diagnosis may generate false positives incurring unnecessary costs. We examined the cost-effectiveness of oral food challenges (OFC) as confirmatory tests in the diagnosis of food allergy. Methods. We constructed a decision tree with a Markov model comparing the long-term (15 years) cost and effectiveness—in the form of quality-adjusted life years (QALY)—of confirmatory OFCs compared with immediate allergenic food elimination (FE) after a skin prick test or blood immunoglobulin E (IgE) level in children with suspected food allergy. For costs, we included the costs of OFCs and the reported annual costs of having a food allergy, including direct medical costs and costs borne by families. Results. The cost of OFC strategy was $8671 compared with $18 012 for the FE strategy for the length of the model. Also, the OFC strategy had a total QALY of 21.942 compared with 21.740 for the FE strategy. In the OFC strategy, the total cost was $9341 less than FE and the increase in QALY after OFCs led to a 0.202 higher effectiveness in the OFC strategy. Conclusion. In conclusion, our study shows that the confirmatory OFC strategy dominated the FE strategy and that a confirmatory OFC for children, within a year of diagnosis, is a cost-effective strategy that decreases costs and appears to improve quality of life.

This paper follows the ‘moral life’ of epinephrine auto-injectors, devices that people with food allergies and their caretakers use to administer emergency medication to stop serious allergic reactions, in the United States. These devices are potent signifiers of the seemingly precarious nature of life with food allergies. I follow auto-injectors from their social birth as a commodity object, through how they structure doctor-patient interactions and parenting, to the ways that parents and illness advocates talk about their life-saving properties. At every step of the way, their significance is influenced by the political-economic context of health care in the United States, which places significant burdens of financial cost and responsibility for deciding what constitutes ‘good’ care upon individual patients and caretakers. The moral life of epinephrine serves as a model for thinking about how medical devices take on meaning that is at once practical, moral, and economic as they circulate through manufacturing and distribution channels and into the lives and social worlds of users.

PURPOSE: US Food and Drug Administration approvals of immune checkpoint inhibitors and targeted therapies revolutionized the treatment of metastatic melanoma. Our aim was to assess health care resource utilization and costs for patients with metastatic melanoma treated with systemic therapies in first line between January 2012 and December 2017. METHODS: We conducted a retrospective cohort study of patients with metastatic melanoma using MarketScan data. We included patients diagnosed with melanoma and secondary malignant neoplasm who used pembrolizumab, nivolumab, ipilimumab, ipilimumab plus nivolumab, BRAF-inhibitor (BRAF-i) plus MEK inhibitor (MEK-i), BRAF-i or MEK-i monotherapy, or chemotherapy in first line. We compared health care utilization and costs per patient per month (PPPM) using two-part and generalized linear models. RESULTS: We identified 1,870 patients, including 185 pembrolizumab, 103 nivolumab, 689 ipilimumab, 185 nivolumab plus ipilimumab, 214 BRAF-i plus MEK-i, 240 BRAF-i or MEK-i monotherapy, and 254 chemotherapy users. Highest PPPM rates of hospitalizations, emergency room visits, and outpatient visits were observed in patients with ipilimumab plus nivolumab therapy (adjusted difference v pembrolizumab [aDiff], 0.18, 0.12, and 0.88, respectively; all P < .001). Ipilimumab monotherapy users (aDiff, 0.07 and 0.93; all P < .001) and chemotherapy users (aDiff, 0.10 and 2.63; all P < .001) showed higher PPPM rates of hospitalizations and outpatient visits compared with pembrolizumab users, respectively. Utilization rates in nivolumab, BRAF-i plus MEK-i, and BRAF-i or MEK-i groups were similar to the pembrolizumab group. Highest PPPM total costs and drug-related costs were observed in the ipilimumab group ($80,139 US dollars [USD] and $70,051 USD; all P < .001), followed by the ipilimumab plus nivolumab ($71,689 USD and $56,217 USD; all P < .001) and the BRAF-i plus MEK-i group ($31,184 USD and $19,648 USD; all P < .001). PPPM costs in the nivolumab group were similar to the pembrolizumab group. CONCLUSION: Significant differences in health care resource utilization and costs were found across first-line metastatic melanoma regimens. Utilization rates were highest in patients using ipilimumab-containing therapies. High drug costs constituted a major fraction of total PPPM health care costs.

Ige Mediated

In recent decades, immunoglobulin E (IgE) mediated food allergy has become a growing public health concern. Converging evidence from cross-sectional prevalence studies, health care utilization records, and cohort studies indicate that food allergies are increasingly prevalent and often severe. Although IgE-mediated food allergy has long been considered a predominantly pediatric concern, analysis of recent self-reported data suggests that food allergies may be more prevalent among adult populations than previously acknowledged, with many reported cases of adult-onset allergies as well as persistent childhood-onset allergies. Results of studies also suggest that food allergy‐related health care utilization is increasing as more individuals seek emergency treatment for food-induced anaphylaxis. Analysis of epidemiologic data also indicates that the burden of food allergies is unequally distributed. Published prevalence rates are highest in Western countries, e.g., the United States, United Kingdom, and Australia. Within these countries, there also is heterogeneity across racial and/or ethnic groups, with non-White and second-generation immigrant populations disproportionately affected. Importantly, such observations can shed light on the etiology of food allergy and inform improved clinical management, treatment, and prevention efforts. For example, there is a growing consensus that earlier introduction of allergenic foods, e.g., peanut, promotes oral tolerance and can dramatically reduce food allergy risk. In addition, much attention has been paid to the potentially deleterious effects of cutaneous allergen exposure, e.g., through eczematous skin, which can skew the immune response away from tolerance and toward allergic sensitization, thereby increasing food allergy risk. Furthermore, there is a growing appreciation for the potential protective effects of diverse microbial exposures, given mounting evidence for the immunomodulatory effects of the human microbiome. Also, when considering the geographic variability in the prevalence of certain food and environmental allergies as well as their structural similarities at the molecular level, it is believed that co-sensitization between food and environmental allergens may be a key driver of rising food allergy prevalence.

The Ideal

Background: Epinephrine is the first-line therapy for patients with anaphylaxis, and intramuscular (IM) delivery is shownto be superior to subcutaneous (SC) delivery. There currently is no consensus on the ideal body position for epinephrine autoinjector (EAI) administration.Objective: We designed this study to investigate whether SC tissue depth (SCTD) is affected by body position (e.g., standing, sitting, supine), which can potentially impact delivery of EAI into the IM space.Methods: Volunteer adults (ages >/= 18 years) from a military medical treatment facility in the United States were recruitedto participate in this study. SCTD of the vastus lateralis was measured via ultrasound at standing, sitting, and supine bodypositions. Subjects’ age, sex, and body mass index (BMI) were collected. Statistical analysis was performed to compare averageSCTD between body positions, sex, and BMI.Results: An analysis of variance of 51 participants (33 men and 18 women) did not reveal statistically significant differencein SCTD among standing, sitting, and supine body positions. It did show a significantly greater SCTD in women than in men (2.72 +/- 1.36 cm versus 1.10 +/- 0.38 cm; p < 0.001). There was no significant association observed between BMI and SCTD in this study.Conclusion: Body position did not seem to significantly change the distance between skin and thigh muscle in adults. Thiswould suggest that there might not be an ideal body position for EAI administration. Therefore, in case of anaphylaxis, promptadministration of epinephrine is recommended at any position.

The primary goal of this study was to examine young adults’ perspectives about the effects of their food allergies (FAs) on their social lives from school-age to young adulthood. Young adults aged 18–21 ( n = 10) at the University of South Carolina were interviewed. A qualitative descriptive method to find themes and commonalities from transcribed interviews was used for data analysis. Identified themes were (1) feeling different and being isolated, (2) strategies for managing feeling different and being isolated, (3) strategies for managing safety, and (4) acceptance of myself and by others. School-age children attributed the school lunch allergy table as contributing to social isolation. Additionally, participants described feeling different and concerns about safety. Strategies to mitigate those experiences were identified by participants. Implications for children with FAs, their parents, school nurses, and other education and health professionals who work with children are presented.

The number of people with cancer and the need for palliative care among this population is increasing in the United States. Despite this growing need, several barriers exist to the utilization of palliative care in oncology. The purpose of this study was to synthesize the evidence on the barriers to palliative care utilization in an oncology population. A systematic review of literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, CINAHL, and Psych Info databases were used for the literature search. Articles were included if they: 1) focused on cancer, (2) examined and discussed barriers to palliative care, and c) were peer reviewed, published in English, and had an accessible full text. A total of 29 studies (8 quantitative, 18 qualitative, and 3 mixed-methods) were identified and synthesized for this review. The sample size of the included studies ranged from 10 participants to 313 participants. The barriers to palliative care were categorized into barriers related to the patient and family, b) barriers related to providers, and c) barriers related to the healthcare system or policy. The factors identified in this review provide guidance for intervention development to mitigate the existing barriers and facilitate the use palliative care in individuals with cancer.
