Purpose: The incidence of the existing respiratory virus and air pollutants had disappeared or decreased due to social distancing during the coronavirus disease 2019 (COVID-19) pandemic. Therefore, there was no increase in asthma exacerbations in 2020. This study aimed to analyze the emergency department (ED) visits of children and adolescent patients with asthma before and after the COVID-19 outbreak and examine the effects of respiratory virus infection and air pollutants., Methods: This study included pediatric and adolescent patients with asthma aged 2-18 years who visited 419 EDs nationwide during February to December in 2018, 2019, and 2020. The patients who were diagnosed with asthma, ie, J45 or J46 (International Classification of Diseases, 10th revision) in the ED medical history, diagnosis history at discharge, and diagnosis at discharge after hospitalization through the ED were included using the National Emergency Department Information System. Data were analyzed by dividing the period as follows: pre-COVID-19 (from February to December 2018 and 2019) and COVID-19 pandemic (from February to December 2020)., Results: The monthly average of 673 visiting patients (95% confidence interval [CI], 474-872) during the pre-COVID-19 period decreased to 176 (95% CI, 113-239) during the COVID-19 pandemic, which is a 73.8% decrease (p < 0.001).In the pre-COVID-19 period, peaks were observed in spring and autumn. Meanwhile, during the COVID-19 pandemic, a peak was observed only during autumn. During the COVID-19 pandemic, no relationship was found between the rhinovirus infection and asthma exacerbations (p < 0.001)., Conclusions: Respiratory virus infections are strongly associated with asthma exacerbations in children and adolescents. In this study, air pollution is not a major factor for ER visits due to asthma exacerbations. Even though the prevalence of respiratory viruses is decreasing, ED visits due to worsening asthma are trending in the fall. This phenomenon may indicate that asthma has worsened due to other causes such as pollen or fluctuations in temperature and air pressure., Competing Interests: The authors report no competing interests., (© 2024 The Authors.)

Objective: To assess recall bias by evaluating how well female cancer survivors remember details regarding their cancer diagnosis, treatment, and fertility preservation (FP) counseling.Oncofertility literature cites recall bias as a pitfall of retrospective surveys, but limited data exist to quantify this bias., Design: Retrospective secondary analysis of cross-sectional survey data., Setting: Single academic medical center., Patients: Female oncology patients of reproductive age, 18-44 years old, at least 6 months past their last chemotherapy treatment., Interventions: Not applicable., Main Outcome Measures: Recall of details surrounding cancer diagnosis and chemotherapy regimens, recall of FP counseling and ovarian reserve testing, and rates of chart-documented FP counseling., Results: In total, 117 patients completed the survey, with 112 verified via chart review. When asked to report the chemotherapy regimen, 57% (64 of the 112) marked "I don't know/prefer not to say." Regarding FP, 80% (90 of the 112) denied being offered counseling. Of the 37 (33%) who had documented FP conversations, 13 (35%) did not recall mention of fertility. Only 2 of 8 patients with ovarian reserve testing recalled this being performed at their initial visit. Multivariable logistic regression revealed older age was significantly associated with not being offered FP (odds ratio [OR] 0.87)., Conclusions: Our results confirm that the accuracy of oncology patients' reporting is limited by a poor recall, particularly regarding their specific chemotherapy regimen. More than 1 in 3 patients documented to have been offered FP counseling do not recall this discussion. Importantly, only one-third of cancer survivors had chart-documented FP counseling. Increased efforts are needed to ensure adequate follow-up beyond the initial visit.

This collaborative statement from the Digital Health Committee of the Heart Rhythm Society provides everyday clinical scenarios in which wearables may be utilized by patients for cardiovascular health and arrhythmia management. We describe herein the spectrum of wearables that are commercially available for patients, and their benefits, shortcomings and areas for technological improvement. Although wearables for rhythm diagnosis and management have not been examined in large randomized clinical trials, undoubtedly the usage of wearables has quickly escalated in clinical practice. This document is the first of a planned series in which we will update information on wearables as they are revised and released to consumers., (© 2021 Published by Elsevier Inc. on behalf of Heart Rhythm Society.)

Background: Although the prevalence of anaphylaxis is increasing worldwide, the large-scale studies in Asia evaluating anaphylaxis in all age groups are limited. We aimed to collect more precise and standardized data on anaphylaxis in Korea using the first multicenter web-based registry., Methods: Twenty-two departments from 16 hospitals participated from November 2016 to December 2018. A web-based case report form, designed by allergy specialists, was used to collect anaphylaxis data., Results: Within the 2-year period, 558 anaphylaxis cases were registered. The age of registered patients ranged from 2 months to 84 years, and 60% were aged <18 years. In children and adolescents, foods (84.8%) were the most common cause of anaphylaxis, followed by drugs (7.2%); in adults, drugs (58.3%) were the most common cause, followed by foods (28.3%) and insect venom (8.1%). The onset time was ≤10 min in 37.6% of patients. Among the 351 cases registered via the emergency department (ED) of participating hospitals, epinephrine was administered to 63.8% of patients. Among those receiving epinephrine in the ED, 13.8% required 2 or more epinephrine shots. Severe anaphylaxis accounted for 23.5% cases (38.1% in adults; 13.7% in children); patients with drug and insect venom-induced anaphylaxis had higher rates of severe anaphylaxis., Conclusion: This multicenter registry provides data on anaphylaxis for all age groups for the first time in Asia. The major causes and severity of anaphylaxis were remarkably different according to age group, and the acute treatment features of anaphylaxis in the EDs were examined in detail., Competing Interests: The authors report no competing interests., (© 2020 The Authors.)
