Considering the importance of diagnosing COVID-19 and the need for reducing the number of false positive and false negative cases that appear to be different in various diagnostic methods, this systematic review aimed at comparison of PCR test accuracy with laboratory data and CT SCAN in COVID-19. Methods: In this systematic review, EMBASE (Elsevier, 2018), MEDLINE (National Library of Medicine, 2018), Scopus, ProQuest, Web of Science (Clarivate Analytics, 2018b), and Google Scholar data bases were searched for the studies published prior to 3 April 2020. Based on the inclusion criteria, 20 out of 859 primarily screened studies were finally assessed. Results: The results indicated that the laboratory diagnosis of viral nucleic acid could have false-negative results, and serological testing of virus-specific IgG and IgM antibodies should be used as an option for diagnosis. Moreover, chest Computerized Tomography (CT) was found to be more sensitive in comparison to Reverse Transcription Polymerase Chain Reaction (RT-PCR) (98% vs. 71%). Hence, the articles offered the combined use of chest CT, SARS-CoV-2 RT-PCR, and multiplex PCR. Conclusion: Follow-up RT-PCR and chest CT are necessary in COVID-19. In addition, serological testing of virus-specific IgG and IgM antibodies along with laboratory diagnosis of viral nucleic acid can lead to the highly sensitive and accurate diagnosis. Moreover, Enzyme-Linked Immunosorbent Assay (ELISA) is one of the cost-effective methods in epidemic conditions in low- and middle-income countries. © 2021 Shriaz University of Medical Sciences.

Methods: We conducted a descriptive cross-sectional study among 817 National Youth Service Corps members. Participants' overall general knowledge about COVID-19 was assessed using nine questions that consisted of general knowledge on the cause, origin, mode of transmission, signs and symptoms, availability of a potent vaccine and specific therapy, prevention strategies of COVID-19 and knowledge of proper handwashing practices. P-values <0.05 were statistically significant. Results: The mean age of the respondents was 24.1±2 years, 317 (41.2%) were males, and 73 (8.9%) had studied a health-related course. Of the 754 respondents who responded to the COVID-19 knowledge questions, 187 (24.8%) had general knowledge about COVID-19, while 280 (37.1%) had knowledge in all domains;mode of spread, symptoms and signs, and prevention of COVID- 19. Among the respondents, 129 (40.7%) males had satisfactory knowledge of COVID-19 (P=0.070), while 38 participants (52.1%) who had studied a health-related course had satisfactory knowledge of COVID-19 (P=0.003). Regarding the knowledge of hand washing, 184 (58%) males displayed satisfactory knowledge (P=0.007). Social media (64.4%) and television (58%) were the main sources of COVID-19 information. Respondents who had studied a health-related course were twice likely to have satisfactory knowledge of COVID-19 (AOR=2, 95% CI=1.25-2.5 P=0.003, ) and six times likely to have satisfactory knowledge of hand washing (AOR=5.6, 95% CI=3.3-10.0, P≤0.0001). Conclusion: Utilization of both social media and the mainstream mass media in disseminating health education information and correcting fake news and misconceptions is needed. Health promotion strategies should be organized for all youths, especially among those who have no previous education in the health and allied courses. © 2021 Shriaz University of Medical Sciences.

At time of this study, the pandemic is still underway, so prevention and control are of great importance. This review provides a comprehensive examination and analysis of the literature related to the challenges of controlling COVID-19. Methods: In this narrative review study, the search was performed on international databases including PubMed, Scopus and Embase, using relevant keywords. The resulting articles and texts were reviewed and screened, and then the relevant information was extracted. Results: The number of patients who are thought to have contracted COVID-19 is much higher than that in the SARS and MERS epidemics. Despite a lower mortality rate, COVID-19 has caused more deaths. One of the challenges that have made the control of the disease more difficult include the emergence of multiple viral mutations. In this review, it was found that the best course of action comprises continuous monitoring of disease-related indicators as part of a series of measures taken together to ensure their effectiveness. Conclusion: It is recommended that governments should form international partnerships in their efforts to overcome the pandemic, and that preventive and control measures should be taken simultaneously. © 2021 Shriaz University of Medical Sciences.

Further, satisfaction is described as the level of the mental happiness, self-confidence and usefulness sensed by caregiver about his/her own caregiving behaviour. The present study aimed to assess the psychometric properties of the Persian version of caregiving satisfaction (SCR) and caregiving burden of grandchildren scales (BCR) among grandparent population by considering the lack of a Persian tool for their measurement. Methods: This cross-sectional, descriptive-analytic study was conducted on 70 grandparents who were selected through convenience sampling among the individuals referred to the healthcare centres of five southern cities in Iran Shiraz, Sepidan, Fasa, Jahrom, and Borazjan from April to August, 2019. The questionnaires were filled out by individual interview with participants and the data were analysed through explanatory and confirmatory factor analyses and ROC curve, using SPSS 25 and Amos 21. Results: Two factors were extracted in each questionnaire (Regarding each questionnaire, happiness and responsibility in individual and social satisfaction in caregiving burden were extracted through explanatory factor analysis), representing 78.1 and 75.1% of total variance, respectively. The Cronbach’s coefficients alpha related to these subscales were obtained as 0.709-0.859 by indicating an acceptable internal consistency. Conclusion: The Persian version of these questionnaires had appropriate validity and reliability required for measuring satisfaction and caregiving burden of grandchildren among Iranian grandparents and can be used in day care and healthcare centres.

In this sense, this study seeks to assess the incidence and fatality of COVID-19 in Europe considering the expected number of the infected cases. Methods: A quantitative exploratory study was performed on the top 10 countries most affected by COVID-19 by 9th June in Europe. Furthermore, this study presents three propagation estimation models of the COVID-19 that help us to understand the real incidence of the pandemic in each country. Each model is briefly explained and applied. Results: The findings revealed a great heterogeneity of COVID19 cases and deaths among the countries. The indicator of the number of deaths reveals the greatest disparity between other countries with the United Kingdom, recording about 6 or 7 times more deaths than Russia or Germany. Infection fatality rate (IFR) tends to be a more reliable indicator when analyzing data because it is less dependent on the number of tests performed. Conclusion: Several estimation models can be used to determine the incidence of COVID-19. However, their results in European countries are still quite asymmetrical although they are more reliable than just looking at the perspective of the number of cases or deaths recorded. The infection fatality rate (IFR) emerges as a more accurate indicator by estimating the expected number of registered cases, which includes asymptomatic cases and patients with mild symptoms that are not known and reported by health authorities.

Methods: Due to some limitation and difficulties to remove these pollutants from the environment, the biological filtering method, as the economically and optimal methods, are preferred. Using the Taguchi method and evaluation of such factors in the environment as temperature pH, color density and concentration of salt, we studied the optimal condition of Halomunas PTCC1132 bacteria decolorization in order to compare it with the Aryapress dye removal from aquatic environment. Therefore, 16 experiments were designed according to Array Table in 4 factors and 4 levels. The results were then analyzed using a computer the program named Qualitek-4.
