- Background: The emergence of the COVID-19 and its consequences has led to fears, worries, and anxiety among individuals worldwide. The present study developed the Fear of COVID-19 Scale (FCV-19S) to complement the clinical efforts in preventing the spread and treating of COVID-19 cases.Methods: The sample comprised 717 Iranian participants. The items of the FCV-19S were constructed based on extensive review of existing scales on fears, expert evaluations, and participant interviews. Several psychometric tests were conducted to ascertain its reliability and validity properties.Results: After panel review and corrected item-total correlation testing, seven items with acceptable corrected item-total correlation (0.47 to 0.56) were retained and further confirmed by significant and strong factor loadings (0.66 to 0.74). Also, other properties evaluated using both classical test theory and Rasch model were satisfactory on the seven-item scale. More specifically, reliability values such as internal consistency (α =.82) and test–retest reliability (ICC =.72) were acceptable. Concurrent validity was supported by the Hospital Anxiety and Depression Scale (with depression, r = 0.425 and anxiety, r = 0.511) and the Perceived Vulnerability to Disease Scale (with perceived infectability, r = 0.483 and germ aversion, r = 0.459).Conclusion: The Fear of COVID-19 Scale, a seven-item scale, has robust psychometric properties. It is reliable and valid in assessing fear of COVID-19 among the general population and will also be useful in allaying COVID-19 fears among individuals.

- Background: Patient safety is a critical issue in healthcare services particularly in surgical units and operation rooms because of the high prevalence and risk of medical errors in such settings. This study was conducted to determine whether a 1-day educational intervention can change the attitude and behavior of surgical residents regarding patient safety.Methods: A total of 90 surgical residents were recruited from 6 university hospitals located in Tehran and Qazvin, Iran, and were randomized to either the intervention or a control group. Those in the intervention group participated in a 1-day workshop on patient safety, whereas the control group received no intervention. Both groups were followed for 3 months after the intervention was completed. The Safety Attitude Questionnaire and Oxford Non-Technical Skills scale were administered at 3 points in time (baseline, 1 month after the intervention, and 3 month later). The data were analyzed using repeated measures analysis of variance.Results: Total score on the Safety Attitude Questionnaire improved from 54.5 (SD = 14.4) at baseline to 58.3 (SD = 13.8) 3 months after the intervention in the intervention group; all dimensions, with the exception of working condition, showed significant changes. In addition, the Oxford Non-Technical Skills scale – as assessed by attending surgeons – improved significantly in all domains (p < 0.05). More than 60% of participants in the intervention group scored in the positive range for items assessing safety and teamwork climate.Conclusions: A 1-day interactive educational workshop may be effective in changing the attitude and practice of surgical residents regarding patient safety. Further assessment of this intervention in other healthcare settings involving health professionals from various specialties and use of an objective measure such as number of reported medical errors are needed to corroborate these findings.

- Background: A mediation model was proposed to explain how religiosity, religious cooping, and fear of coronavirus disease 2019 (COVID-19) explained anxiety and depression among older adults. Methods: With the use of a cross-sectional design, the Integrated Health System was used to randomly invite 1000 older adults residing in Qazvin to participate in an online survey. Within the period of November, 2020 to January 2021, 696 older Iranian adults (mean age = 69.56 years; 57.9% women) agreed to participate in the study and reported demographic information as well as measures of religiosity, fear of COVID-19, religious coping, anxiety, and depression. Results: Religiosity had direct effects on depression (B [SE] = -0.087 [0.037]; P = 0.023) but not anxiety (B [SE]=-0.063 [0.036]; P = 0.072). Moreover, both fear of COVID-19 and religious coping significantly mediated the association between religiosity and anxiety (B [SE] = -0.360 [0.035]; p = 0.002) and that between religiosity and depression (B [SE] = -0.365 [0.034]; P = 0.002). Conclusion: During the tough time of COVID-19 pandemic, religiosity and religious coping were protectors for older adults in developing good mental. Therefore, future research is needed to examine education programs that are effective for older adults to obtain correct knowledge concerning COVID-19, including the protective COVID-19 infection behaviors. Therefore, older adults may reduce their fear via their enhanced correct knowledge concerning COVID-19.

- Purpose: To examine the psychometric properties of the Sleep Condition Indicator (SCI) using different psychometric approaches [including classical test theory, Rasch models, and receiver operating characteristics (ROC) curve] among patients with advanced cancer.Methods: Through convenience sampling, patients with cancer at stage III or IV (n = 859; 511 males; mean ± SD age = 67.4 ± 7.5 years) were recruited from several oncology units of university hospitals in Iran. All the participants completed the SCI, Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire (GHQ), and Edmonton Symptom Assessment Scale (ESAS). In addition, 491 participants wore an actigraph device to capture objective sleep.Results: Classical test theory [factor loadings from confirmatory factor analysis = 0.76–0.89; test–retest reliability = 0.80–0.93] and Rasch analysis [infit mean square (MnSq) = 0.63–1.31; outfit MnSq = 0.61–1.23] both support the construct validity of the SCI. The SCI had significant associations with ISI, PSQI, ESS, HADS, GHQ, and ESAS. In addition, the SCI has satisfactory area under ROC curve (0.92) when comparing a gold standard of insomnia diagnosis. Significant differences in the actigraphy measure were found between insomniacs and non-insomniacs based on the SCI score defined by ROC.Conclusion: With the promising psychometric properties shown in the SCI, healthcare providers can use this simple assessment tool to target the patients with advanced cancer who are at risk of insomnia and subsequently provide personalized care efficiently.

- The epidemiologic information demonstrates the importance of caring people with epilepsy (PWE). Indeed, the impaired quality of life (QoL) and medication nonadherence rate among PWE have been reported. However, religiosity and religious coping could be potential factors for clinicians to foster appropriate intervention on epileptic care. This study investigated two models to further understand the relationships between religiosity, religious coping (including positive and negative coping), medication adherence, and QoL in an Iranian sample with epilepsy. Eligible PWE (n = 760) completed the religiosity scale (Duke University Religion Index; DUREL) at baseline; the religious coping scale (Brief Religious Coping Scale; Brief RCOPE) one month later; the medication adherence scale (Medication Adherence Report Scale; MARS-5) two months later; and the QoL scale (Quality of Life in Epilepsy; QOLIE-31) twelve months later. Their antiepileptic drug serum level was measured during the period they completed the MARS. Through structural equation modeling (SEM), we found that religiosity directly correlated with negative religious coping and medication adherence, and indirectly correlated with medication adherence through negative religious coping. Both positive and negative religious coping directly correlated with medication adherence and QoL. Therefore, religiosity and religious coping may be determinants of medication adherence and QoL in PWE; health professionals may consider asking PWE if religion is important to them and how they use it to cope with their epilepsy.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Patients with COVID-19 often suffer from psychological problems such as post-traumatic stress disorder (PTSD) and self-stigmatization that may negatively impact their quality of life and sleep. This study examined mental health as a potential mediating factor linking self-stigmatization and PTSD to quality of life and sleep. Methods: Using a cross-sectional design, 844 people who had recovered from COVID-19 were called and interviewed. Data were collected using structured scales. Structural equation modeling was applied to assess fitness of a mediation model including self-stigma and PTSD as independent factors and quality of life and insomnia as dependent variables. Results: Mental health, COVID-19-related self-stigma, and mental quality of life were associated. Insomnia, PTSD, and COVID-19-related self-stigma displayed significant direct associations (r =.334 to 0.454; p <.01). A mediation model indicated satisfactory goodness of fit (CFI = 0.968, TLI = 0.950, SRMR = 0.071, RMSEA = 0.068). Mental health as a mediator had negative relationships with COVID-19-related self-stigma, PTSD, and insomnia and positive associations with quality of life. Conclusion: Mental health may mediate effects of COVID-19-related self-stigma and PTSD on quality of life and insomnia. Designing programs to improve mental health among patients with COVID-19 may include efforts to reduce negative effects of PTSD and COVID-19-related self-stigma on quality of life and insomnia.

- Non-equilibrium phenomena and related damages have always been one of the great concerns among researchers, designers, and industry managers. In power plants, the overhaul of turbines during a pre-planned schedule includes checking, repairing, and replacing damaged parts, which always challenge industry investors with variable costs. In this study, a modified profile for the stationary cascade blades of a 200 MW steam turbine is predicted by help of the Computational Fluid Dynamics (CFD) according to a cost-saving approach for a power plant. Wet steam model is used to investigate the flow behavior between the turbine blades, due to the sonication and non-equilibrium phenomena. The numerical model based on the Eulerian-Eulerian approach accounts the turbulence caused by the presence of droplets, condensation shocks and aerodynamics. At first, such model has been carefully validated against the available experimental data. Then, the entrance edge of the blade is designed considering different shapes and sizes. The flow behavior at the entrance edge region has been fully investigated. Finally, according to the criteria for measuring the non-equilibrium flow phenomena (erosion rate, Mach number, entropy, exergy destruction and transfer of mass and heat between flow phases), a modified model for the steam turbine blade considering the economic aspects has been presented. The modified blade model exhibits 88%, 0.13% and 7% reduction in the erosion rate, entropy generation and exergy destruction, respectively. Furthermore, the application of this modified blade profile save 456$ of the total monthly maintenance costs.
