    An assessment of post-COVID-19 infection pulmonary functions in healthcare professionals
    (Mosby-Elsevier, 2022) Gülhan, Pınar Y.; Arbak, Peri M.; Annakkaya, Ali N.; Balbay, Ege Güleç; Balbay, Öner A.
    Background: The medium- and long-term effects of COVID-19 infection on pulmonary function are still unknown. The present study aimed to investigate the pulmonary functions in healthcare professionals who had persistent complaints after contracting COVID-19 and returning to work. Methods: The study included COVID-19-infected healthcare professionals from the Dueurozce University Medical Faculty Hospital who volunteered to participate. Medical histories, medical records, pulmonary function tests, the diffusing capacity of the lungs for carbon monoxide (DLCO) test, and the 6-minute walk test (6MWT) were used to collect data from all participants. Results: The study included 53 healthcare professionals, with an average age of 38 +/- 10 years (min: 24 years and max: 71 years), including 29 female (54.7%) and 24 male (45.3%) participants. Of the participants, 22.6% were smokers, 35.8% (19 individuals) had comorbidities, and 17% (9 individuals) were hospitalized. The mean length of stay was 9 +/- 4 days (mean +/- standard deviation). The most prevalent symptoms were weakness (88.7%), muscle aches (67.9%), inability to smell/taste (60.4%), headache (54.7%), fever (45.3%), cough (41.5%), and shortness of breath (37.7%). The mean time to return to work after a positive polymerase chain reaction (PCR) test for COVID-19 was 18 +/- 13 days. The average time among post-disease pulmonary function, 6MW, and DLCO tests was 89 +/- 36 days (min: 15 and max: 205). The DLCO level decreased in 39.6% (21) of the participants. Female participants had a significantly higher rate of decreased DLCO levels than male participants (25% vs. 55.2%, P = .026). DLCO levels were significantly higher in participants with longterm persistent complaints (P = .043). The later the time to return to work, the lower the DLCO value (r=-0.290 and P = .035). The 6MWT distance was positively correlated with hemoglobin and lymphocyte levels at the time of the disease onset and negatively correlated with D-dimer levels. The most prevalent symptoms during the control visits were shortness of breath/effort dyspnea (24.6%), weakness (9.5%), and muscle aches (7.6%). Conclusion: Significant persistent complaints (47.2%) and low DLCO levels (39.6%) were observed in healthcare professionals during control visits at a mean time of 3 months after the COVID-19 infection. Symptoms and spirometry measurements, including DLCO, may be helpful in the follow-up of healthcare professionals who contracted COVID-19. Further comprehensive studies with long-term follow-up periods are required. (c) 2022 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

    COVID-19 vaccination and associated factors in Turkish healthcare workers practicing chest medicine
    (Wolters Kluwer Medknow Publications, 2023) Sandal, Abdulsamet; Cifci, Aylin Gungor; Arbak, Peri M.
    Objective: To evaluate the COVID-19 vaccination status and related characteristics of Turkish healthcare workers practicing chest medicine.Methods: A cross-sectional online survey was conducted among the Turkish Thoracic Society members. The survey was started on May 17, 2021, and kept open for seven weeks. The 39-item survey included the COVID-19 vaccination status and demographic, clinical, and occupational characteristics.Results: Of 378 healthcare workers participated in the survey, 354 (93.7%) reported receiving at least one dose of the COVID-19 vaccine. A total of 323 (91.2%) healthcare workers received CoronaVac vs. BioNTech/Pfizer in 31 (8.8%). In the CoronaVac group, 77 (23.8%) contracted COVID-19 when not fully vaccinated, and 13 (4.0%) when fully vaccinated; however, 16 (51.6%) healthcare workers in the BioNTech/Pfizer group got COVID-19 when not fully vaccinated, but any fully vaccinated participants did not contract COVID-19 (P=0.003). Regarding vaccine dosing, 328 (86.8%) were fully vaccinated, while 50 (13.2%) were not. Multiple regression analysis for being a non-fully vaccinated healthcare worker demonstrated a significant relationship with having any SARS-CoV-2 infection history (adjusted OR 9.57, 95% CI 3.93-23.26, P<0.001) and being a non-physician healthcare worker (adjusted OR 5.86, 95% CI 2.11-16.26, P=0.001), but a significant negative relationship with full-time working at the time of survey (adjusted OR 0.13, 95% CI 0.03-0.56, P=0.006).Conclusions: Although a majority of healthcare workers were fully vaccinated, occupational and non-occupational characteristics were related to being non-fully vaccinated. Active surveillance regarding the COVID-19 vaccination in healthcare workers is necessary to address specific parameters as barriers to vaccination.
