Article Perceived Stress and Performance of Daily Activities Among Emergency Healthcare Workers During the COVID-19 Pandemic(Sage Publications Ltd, 2025) Yücel, Hülya; Bektas, Selen AydonerBackground: During the COVID-19 pandemic, healthcare workers were exposed to intense stress in the emergency departments and sudden changes in their daily lives. Objective: The study aimed to investigate the impact of the pandemic on performance and participation in the activities of daily living, personal lives, and overall well-being of the healthcare workers in an emergency department. Methods: Seventy-eight people working in an emergency department of a university hospital (100% of those eligible) participated in the study during June-July 2022. A self-report survey, cross-sectional design was used to collect data. Participants completed the Perceived Stress Scale-10 (PSS) and the Canadian Occupational Performance Measure (COPM). Independent sample t-tests, Pearson correlation, and multiple regression analysis were used for statistical analysis. Results: There was a significant negative correlation between PSS and COPM Performance (r = −0.524) as well as between PSS and COPM Satisfaction (r = −0.508), indicating that higher levels of stress were associated with lower performance and satisfaction. In addition, work-related factors, including working experience, daily working hours, and time available for rest at work, were significantly associated with PSS, COPM Performance, and Satisfaction (p < 0.05). The strongest multivariate associations (p = 0.001) were found between lacking time to rest at work and PSS (direct) and COPM Performance and Satisfaction (inverse). Conclusion: The stress experienced by emergency healthcare workers during COVID-19 negatively impacted their performance, daily activities, personal lives, and well-being. A potential implication is that policy-makers addressing work-related factors and implementing regulations could improve the well-being of these workers in their professional practices. © 2025 Elsevier B.V., All rights reserved.Article Citation - WoS: 1Citation - Scopus: 1In Silico Evaluation of H1-Antihistamine as Potential Inhibitors of SARS-CoV RNA-Dependent RNA Polymerase: Repurposing Study of COVID-19 Therapy(Turkish Pharmacists Association, 2024) Küçükgüzel, İlkay; Kulabaş, Necla; Hamdan, MazınIntroduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), from the family Coronaviridae, is the seventh known coronavirus to infect humans and cause acute respiratory syndrome. Although vaccination efforts have been conducted against this virus, which emerged in Wuhan, China, in December 2019 and has spread rapidly around the world, the lack of an Food and Drug Administration-approved antiviral agent has made drug repurposing an important approach for emergency response during the COVID-19 pandemic. The aim of this study was to investigate the potential of H1-antihistamines as antiviral agents against SARS-CoV-2 RNA-dependent RNA polymerase enzyme. Materials and Methods: Using molecular docking techniques, we explored the interactions between H1-antihistamines and RNA-dependent RNA polymerase (RdRp), a key enzyme involved in viral replication. The three-dimensional structure of 37 H1-antihistamine molecules was drawn and their energies were minimized using Spartan 0.4. Subsequently, we conducted a docking study with Autodock Vina to assess the binding affinity of these molecules to the target site. The docking scores and conformations were then visualized using Discovery Studio. Results: The results examined showed that the docking scores of the H1-antihistamines were between 5.0 and 8.3 kcal/mol. These findings suggested that among all the analyzed drugs, bilastine, fexofenadine, montelukast, zafirlukast, mizolastine, and rupatadine might bind with the best binding energy (< -7.0 kcal/mol) and inhibit RdRp, potentially halting the replication of the virus. Conclusion: This study highlights the potential of H1-antihistamines in combating COVID-19 and underscores the value of computational approaches in rapid drug discovery and repurposing efforts. Finally, experimental studies are required to measure the potency of H1-antihistamines before their clinical use against COVID-19 as RdRp inhibitors.
