Updated Guidance Regarding The Risk ofAllergic Reactions to COVID-19 Vaccines and Recommended Evaluation and Management: A GRADE Assessment, and International Consensus Approach
This guidance updates 2021 GRADE (Grading of Recommendations Assessment, Development and Evaluation) recommendations regarding immediate allergic reactions following coronavirus disease 2019 (COVID-19) vaccines and addresses revaccinating individuals with first-dose allergic reactions and allergy testing to determine revaccination outcomes. Recent meta-analyses assessed the incidence of severe allergic reactions to initial COVID-19 vaccination, risk of mRNA-COVID-19 revaccination after an initial reaction, and diagnostic accuracy of COVID-19 vaccine and vaccine excipient testing in predicting reactions. GRADE methods informed rating the certainty of evidence and strength of recommendations. A modified Delphi panel consisting of experts in allergy, anaphylaxis, vaccinology, infectious diseases, emergency medicine, and primary care from Australia, Canada, Europe, Japan, South Africa, the United Kingdom, and the United States formed the recommendations. We recommend vaccination for persons without COVID-19 vaccine excipient allergy and revaccination after a prior immediate allergic reaction. We suggest against \u3e 15-minute postvaccination observation. We recommend against mRNA vaccine or excipient skin testing to predict outcomes. We suggest revaccination of persons with an immediate allergic reaction to the mRNA vaccine or excipients be performed by a person with vaccine allergy expertise in a properly equipped setting. We suggest against premedication, split-dosing, or special precautions because of a comorbid allergic history
Global economic burden of unmet surgical need for appendicitis
Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US 73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was 75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
Paediatric Allergy Practice in the Era of Coronavirus Disease 2019
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

Media Influence on Anxiety, Health Utility, and Health Beliefs Early in the SARS-CoV-2 Pandemic-a Survey Study
© Society of General Internal Medicine 2021. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1007/s11606-020-06554-yBackground: The psychological effects from the COVID-19 pandemic and response are poorly understood. Objective: To understand the effects of the pandemic and response on anxiety and health utility in a nationally representative sample of US adults. Design: A de-identified, cross-sectional survey was administered at the end of April 2020. Probability weights were assigned using estimates from the 2018 American Community Survey and Integrated Public Use Microdata Series Estimates. Participants: US adults 18–85 years of age with landline, texting-enabled cellphone, or internet access. Intervention: Seven split-half survey blocks of 30 questions, assessing demographics, COVID-19-related health attitudes, and standardized measures of generalized self-efficacy, anxiety, depression, personality, and generic health utility. Main Measures: State/Trait anxiety scores, EQ-5D-3L Visual Analog Scale (VAS) score, and demographic predictors of these scores. Key Results: Among 4855 respondents, 56.7% checked COVID-19-related news several times daily, and 84.4% at least once daily. Only 65.7% desired SARS-CoV-2 vaccination for themselves, and 70.1% for their child. Mean state anxiety (S-anxiety) score was significantly higher than mean trait anxiety (T-anxiety) score (44.9, 95%CI 43.5–46.3 vs. 41.6, 95%CI 38.7–44.5; p = 0.03), with both scores significantly higher than previously published norms. In an adjusted regression model, less frequent news viewing was associated with significantly lower S-anxiety score. Mean EQ-5D-3L VAS score for the population was significantly lower vs. established US normative data (71.4 CI 67.4–75.5, std. error 2 vs. societal mean 80, std. error 0.1; p < 0.001). EQ-5D-3L VAS score was bimodal (highest with hourly and no viewing) and significantly reduced with less media viewership in an adjusted model. Conclusions: Among a nationally representative sample, there were higher S-anxiety and lower EQ-5D-3L VAS scores compared to non-pandemic normative data, indicative of a potential detrimental acute effect of the pandemic. More frequent daily media viewership was significantly associated with higher S-anxiety but also predictive of higher health utility, as measured by EQ-5D-3L VAS scores.Peer reviewe
Diagnostic accuracy of vaccine and vaccine excipient testing in the setting of allergic reactions to COVID-19 vaccines: AÂ systematic review and meta-analysis
For persons with immediate allergic reactions to mRNA COVID-19 vaccines, skin testing (ST) to the vaccine/excipients (polyethylene glycol[PEG] and polysorbate 80 [PS]) has been recommended, but has unknown accuracy. To assess vaccine/excipient ST accuracy in predicting all-severity immediate allergic reactions upon re-vaccination, systematic review was performed searching Medline, EMBASE, Web of Science, and the WHO global coronavirus database (inception-Oct 4, 2021) for studies addressing immediate (≤4 h post-vaccination) all-severity allergic reactions to 2nd mRNA COVID-19 vaccination in persons with 1st dose immediate allergic reactions. Cases evaluating delayed reactions, change of vaccine platform, or revaccination without vaccine/excipient ST were excluded. Meta-analysis of diagnostic testing accuracy was performed using Bayesian methods. The GRADE approach evaluated certainty of the evidence, and QUADAS-2 assessed risk of bias. Among 20 studies of mRNA COVID-19 first dose vaccine reactions, 317 individuals underwent 578 ST to any one or combination of vaccine, PEG, or PS, and were re-vaccinated with the same vaccine. Test sensitivity for either mRNA vaccine was 0.2 (95%CrI 0.01–0.52) and specificity 0.97 (95%CrI 0.9–1). PEG test sensitivity was 0.02 (95%CrI 0.00–0.07) and specificity 0.99 (95%CrI 0.96–1). PS test sensitivity was 0.03 (95%CrI 0.00–0.0.11) and specificity 0.97 (95%CrI 0.91–1). Combined for use of any of the 3 testing agents, sensitivity was 0.03 (95%CrI 0.00–0.08) and specificity was 0.98 (95%CrI 0.95–1.00). Certainty of evidence was moderate. ST has low sensitivity but high specificity in predicting all-severity repeat immediate allergic reactions to the same agent, among persons with 1st dose immediate allergic reactions to mRNA COVID-19 vaccines. mRNA COVID-19 vaccine or excipient ST has limited risk assessment utility.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/175406/1/all15571-sup-0003-supplementaryfigureE2.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/175406/2/all15571-sup-0002-supplementaryfigureE1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/175406/3/all15571_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/175406/4/all15571.pd
The Turing test track of the 2012 Mario AI championship: entries and evaluation
The Turing Test Track of the Mario AI Championship focused on developing human-like controllers for a clone of the popular game Super Mario Bros. Competitors participated by submitting AI agents that imitate human playing style. This paper presents the rules of the competition, the software used, the voting interface, the scoring procedure, the submitted controllers and the recent results of the competition for the year 2012. We also discuss what can be learnt from this competition in terms of believability in platform games. The discussion is supported by a statistical analysis of behavioural similarities and differences among the agents, and between agents and humans. The paper is co-authored by the organizers of the competition (the first three authors) and the competitors
Extrapolating Evidence Based Medicine of AIT into Clinical Practice in the US
Allergy/immunology specialists in the US prescribing allergy immunotherapy (AIT) have placed a heavy value on practical experience and anecdotal evidence rather than research-based evidence. With the extensive research on AIT conducted in the last few decades, the time has come to better implement evidence-based medicine (EBM) for AIT. The goal of this review was to critically assess EBM for debated concepts in US AIT practice for respiratory allergies in the context and quality of today\u27s regulatory standards. Debated topics reviewed were the efficacy and safety of AIT in various subgroups (e.g., polyallergic patients, older patients, patients with asthma, pregnant women), diagnosis topics (e.g., skin prick test vs allergen-specific serum IgE, factors affecting skin prick tests, use of nasal or conjunctival allergen challenges, and telemedicine for diagnosis), and dosing topics (e.g., optimal dosing for subcutaneous immunotherapy and sublingual immunotherapy tablets, US liquid allergen extract history, duration of treatment, biomarkers of efficacy). In addition, EBM for patient-centered AIT issues (e.g., adherence, use of practice guidelines, pharmacoeconomics) and the approach to implementation of AIT EBM in future clinical practice was also addressed. The EBM for each concept was briefly summarized, and when possible, a practical, concise recommendation was given
