“…COVID-19 is a highly virulent infectious disease that has spread globally at an alarming rate. The first case of COVID-19 was reported in the Chinese city of Wuhan, Hubei Province, in December 2019 (Özkarafakılı et al ., 2022). Subsequently, COVID-19 was declared a global pandemic by the WHO (World Health Organization) on 11 March 2020 (Schneider, 2021).…”

PurposeThe fear of COVID-19 has been identified as a significant predictor of adverse work-related outcomes. Grounded on conservation of resource theory, this study examines the impact of fear of COVID-19 on faculty members' job turnover intention (TI) and job insecurity, as well as the relationship between job insecurity and TI. Additionally, the authors investigate job insecurity as a potential mediating variable between the fear of COVID-19 and TI.Design/methodology/approachData were collected from faculty members (n = 226) working in Pakistan's public sector universities and analysed through PLS-SEM using SmartPLS software.FindingsThe results indicated that fear of COVID-19 was positively and significantly associated with both TI and job insecurity. Furthermore, the results demonstrate that job insecurity has a positive correlation with TI. In addition, the study's findings endorsed the mediating role of job insecurity between fear of COVID-19 and TI.Practical implicationsThe study highlights the importance of addressing the fear of COVID-19 and job insecurity among faculty members, as they are significant predictors of TI. The findings suggest employers should prioritise providing a safe work environment and reducing uncertainty to retain their workforce during the pandemic.Originality/value This study adds to the literature as it conceptualises the indirect mechanism that links fear of COVID-19 to TI and job insecurity and provides practical implications that may reduce faculty members' TI.

BackgroundChest computerized tomography (CT) plays an important role in detecting patients with suspected coronavirus disease 2019 (COVID-19), however, there are no systematic summaries on whether the chest CT findings of patients within mainland China are applicable to those found in patients outside.MethodsRelevant studies were retrieved comprehensively by searching PubMed, Embase, and Cochrane Library databases before 15 April 2022. Quality assessment of diagnostic accuracy studies (QUADAS) was used to evaluate the quality of the included studies, which were divided into two groups according to whether they were in mainland China or outside. Data on diagnostic performance, unilateral or bilateral lung involvement, and typical chest CT imaging appearances were extracted, and then, meta-analyses were performed with R software to compare the CT features of COVID-19 pneumonia between patients from within and outside mainland China.ResultsOf the 8,258 studies screened, 19 studies with 3,400 patients in mainland China and 14 studies with 554 outside mainland China were included. Overall, the risk of quality assessment and publication bias was low. The diagnostic value of chest CT is similar between patients from within and outside mainland China (93, 91%). The pooled incidence of unilateral lung involvement (15, 7%), the crazy-paving sign (31, 21%), mixed ground-glass opacities (GGO) and consolidations (51, 35%), air bronchogram (44, 25%), vascular engorgement (59, 33%), bronchial wall thickening (19, 12%), and septal thickening (39, 26%) in patients from mainland China were significantly higher than those from outside; however, the incidence rates of bilateral lung involvement (75, 84%), GGO (78, 87%), consolidations (45, 58%), nodules (12, 17%), and pleural effusion (9, 15%) were significantly lower.ConclusionConsidering that the chest CT features of patients in mainland China may not reflect those of the patients abroad, radiologists and clinicians should be familiar with various CT presentations suggestive of COVID-19 in different regions.
