Psychological aspects of COVID-19 in Iran: how the disease may affect mental health of medical staff and general population?

Introduction: The disease related to the coronavirus disease 2019 (COVID-19) has now been a pandemic throughout the world. Although the epidemiological studies and clinical trials are utilized to find standard measures and medicines to prevent and control COVID-19, addressing the mental health and psychology of the people who may be at risk of the disease may also be effective to find comprehensive methods to better overcome this pandemic. This study aimed at investigating the mental status of both the general population and healthcare personnel during this pandemic in Iran.

Introduction and Objectives: The pivotal role of chest computed tomographic (CT) to diagnosis and prognosis coronavirus disease-2019 (COVID-19) is still an open field to be explored. This study was conducted to assess the CT features in confirmed cases with COVID-19. Materials and Methods: Retrospectively, initial chest CT data of 363 confirmed cases with COVID-19 were reviewed. All subjects were stratified into three groups based on patients' clinical outcomes; non-critical group (n=194), critical group (n=65), and death group (n=104). The detailed of CT findings were collected from patients' medical records and then evaluated for each group. In addition, multinomial logistic regression was used to analyze risk factors according to CT findings in three groups of patients with COVID-19. Results: Compared with the non-critical group, mixed ground-glass opacities (GGO) and consolidation lesion, pleural effusion lesion, presence of diffuse opacity in cases, more than 2 lobes involved and opacity scores were significantly higher in the critical and death groups (P<0.05). Having more mixed GGO with consolidation, pleural effusion, lack of pure GGO, more diffuse opacity, involvement of more than 2 lobes and high opacity score identified as independent risk factors of critical and death groups. Conclusion: CT images of non-critical, critical and death groups with COVID-19 had definite characteristics. CT examination plays a vital role in managing the current COVID-19 outbreak, for early detection of COVID-19 pneumonia. In addition, initial CT findings may be useful to stratify patients, which have a potentially important utility in the current global medical situation.
