ABSTRACT
Background: Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) is a life-threatening invasive fungal infection in critically ill patients with COVID-19. However, only a few studies have reported CAPA in the Republic of Korea. Objective: To describe clinical characteristics of CAPA in patients at a tertiary care hospital in the Republic of Korea. Methods: This retrospective, observational consecutive case series study was conducted by reviewing the electronic medical records of patients who developed CAPA at Seoul National University Hospital from January 1, 2020, to August 31, 2021. CAPA was defined by European Confederation of Medical Mycology/International Society for Human and Animal Mycology (ECMM/ISHAM) consensus criteria. Patient demographics, comorbidities, corticosteroid use, clinical presentation, treatment, and outcomes were investigated. Results: Eleven patients were diagnosed with probable CAPA according to the ECMM/ISHAM criteria. One patient had classical host factor for invasive pulmonary aspergillosis before admission. All patients received corticosteroid therapy before CAPA diagnosis. The mean total corticosteroid administered before CAPA diagnosis was 220 mg of dexamethasone equivalent dose (range, 80~572 mg), and the mean duration of steroid therapy was 15 days (range, 4~34 days). The median time from intensive care unit admission to CAPA diagnosis was 12 days (range, 5~36 days). All individuals showed aggravation on chest X-rays. Ten patients were diagnosed with positive serum galactomannan (GM), and one was diagnosed with positive GM in a bronchoalveolar lavage specimen. Of the 11 patients, 8 received voriconazole-based antifungal therapy for a median of 30.5 days. Only two patients survived after antifungal treatment. Conclusion: These cases illustrate CAPA complicated in critically ill COVID-19 patients. The challenges in diagnosis and poor outcomes of CAPA emphasize the clinical suspicion and needs for further investigation. Copyright@2022 by The Korean Society for Medical Mycology.

ABSTRACT
Background: During the novel coronavirus-2019 (COVID-19) pandemic, physicians in residency and fellowship training programs are serving as essential healthcare workers while also attempting to continue their preparation for eventual independent practice in their field. We aimed to determine how level of exposure patients with COVID-19 affected the experience of graduate medical trainees in terms of their safety, professional development, and well-being during March and April 2020 Methods: We administered an anonymous, voluntary, web-based survey to physicians enrolled in residency or fellowship training programs in any specialty worldwide A convenience sampling of trainees was obtained through distribution of the survey by email and social media posts from April 20th to May 11th, 2020 To investigate the impact of burden of exposure to COVID-19 the trainee experience, we categorized respondents according to their self-reported estimate of the number of patients with COVID-19 that they provided care for in March and April 2020 (0, 1-30, 31-60, >60). Descriptive statistics were performed and the chi square test was used to evaluate for statistical significance. A multivariable logistic regression analysis was conducted to determine independent predictors of physician burnout Results: Surveys were completed by 1420 trainees, of whom 1031 (73%) were residents Most of the fellows who responded to the survey were training in gastroenterology/ hepatology (27%, 85/280) Trainees who cared for a greater number of COVID-19 patients were more likely to report limited access to PPE and COVID-19 testing and more likely to report testing positive for COVID-19 (Figure 1A) Compared to trainees who did not take care of COVID-19 patients, those who took care of 1-30 patients (adjusted odds ratio [AOR] 1 80, 95% CI 1 29-2 51), 31-60 patients (AOR 3.30, 95% CI 1.86-5.88) and >60 patients (AOR 4.03, 95% CI 2 12-7 63) were increasingly more likely to report burnout More than half (835, 58%) of trainees reported concern about their future preparedness for independent practice Trainees who cared for >60 COVID-19 patients compared to those who did not care for any COVID-19 patients reported similar levels of concern about their preparedness for independent practice (56%, 372/636 vs 58%, 71/125 respectively, p-value 0 57, Figure 1B) Conclusion: Physician trainees who were involved in the care of patients with COVID-19 were more likely to report unsafe working conditions and suffered from higher rates of physician burnout Trainees were concerned about the effects of lost training opportunities on their professional development irrespective of the number of COVID-19 patients they cared for.
ABSTRACT
Background: From May to July 2015, the Republic of Korea experienced the largest outbreak of Middle East respiratory syndrome (MERS) outside the Arabian Peninsula. A total of 186 patients, including 36 deaths, had been diagnosed with MERS-coronavirus (MERS-CoV) infection as of September 30th, 2015. Materials and Methods: We obtained information of patients who were confirmed to have MERS-CoV infection. MERS-CoV infection was diagnosed using real-time reverse-transcriptase polymerase chain reaction assay. Results: The median age of the patients was 55 years (range, 16 to 86). A total of 55.4% of the patients had one or more coexisting medical conditions. The most common symptom was fever (95.2%). At admission, leukopenia (42.6%), thrombocytopenia (46.6%), and elevation of aspartate aminotransferase (42.7%) were observed. Pneumonia was detected in 68.3% of patients at admission and developed in 80.8% during the disease course. Antiviral agents were used for 74.7% of patients. Mechanical ventilation, extracorporeal membrane oxygenation, and convalescent serum were employed for 24.5%, 7.1%, and 3.8% of patients, respectively. Older age, presence of coexisting medical conditions including diabetes or chronic lung disease, presence of dyspnea, hypotension, and leukocytosis at admission, and the use of mechanical ventilation were revealed to be independent predictors of death. Conclusion: The clinical features of MERS-CoV infection in the Republic of Korea were similar to those of previous outbreaks in the Middle East. However, the overall mortality rate (20.4%) was lower than that in previous reports. Enhanced surveillance and active management of patients during the outbreak may have resulted in improved outcomes. FAU - Choi, Won Suk
ABSTRACT
Background: There are few data about long-term respiratory complications following Middle East Respiratory Syndrome coronavirus (MERS-CoV) infection. This study aimed to evaluate respiratory functions and radiologic sequelae according to the severity of infection one year after the patients experienced MERS-CoV infection. Methods: A total of 73 patients undergoing MERS-CoV infection during the 2015 MERS outbreak in South Korea were enrolled in this prospective multicenter study. Pulmonary function tests and 6-minute walking tests were performed 1 year after infection. Radiologic sequelae was defined as fibrosis or atelectasis on chest computer tomography and severe pneumonia was defined as that requiring oxygen therapy. Multivariate linear regression tests were used to evaluate the effect of infection severity on respiratory function. Results: At the time of MERS-CoV infection, 18 patients had no pneumonia, 35 experienced mild pneumonia, and 20 did severe pneumonia. The median age was not different between groups (P = 0.942). Forced vital capacity (FVC) was 102.6%, 94.9%, and 88.7% in the no, mild, and severe pneumonia group, respectively (P = 0.010) and forced expiratory volume in 1 second was 105.3%, 95.7%, and 91.7% (P = 0.057). Diffusing capacity (DLCO) was significantly lower in the severe pneumonia group than in the no or mild pneumonia group (78.3% vs. 89.4% or 88.6%, P = 0.035). In multivariate analyses, FVC and DLCO were significantly correlated with infection severity after adjustment with age, sex, underlying lung disease, and smoking. There was no difference in the walking distance of 6 minute tests between groups. Radiologic sequelae were shown in 18.8%, 65.6%, and 100% in the no, mild, and severe pneumonia group, respectively (P < 0.001). Conclusion: The patients with more severe pneumonia by MERS-CoV had more impaired respiratory function in one year follow-up, which was compatible with radiologic sequelae.
