Abstract
Background and Objectives: The study aimed to analysis the psychometric properties of the health system resilience scale, assessing it and to introduce a conceptual model for qualitative analysis of Iran health system in the face of the civid-19 crisis.
Methods: In this Mixed-method study, the determination of face and content validity was performed using 8 experts. The structure validity was investigated in a cross-sectional study through an electronic survey of 178 actors in the Iran health system. Resilience has been assessed in five dimensions using 5point Likert scale.
Results: The percentage mean score of the Iranian health system resilience in the face of the Covid19 crisis was 41/08 and in the moderate level. The percentage mean score (standard deviation) for 5 dimension include awareness 39/2 (21), diversity 38/7 (21), self-regulation 36 (20/6), integration 39/9 (21/5) and adaptation 41/2 (21/8). Confirmatory factor analysis indicated the appropriate fit of the information with the five-component structure.
Conclusion: The maximum score of resilience dimension belongs to adaptation and the lowest to the self-regulation indicating that it requires interventions to involve the private sector, and to design a new delivery system for crisis situations. The questionnaire can be used as a standard instrument for assessing the health system resilience.

Abstract
COVID-19 has now turned into a global crisis affecting all sections of economy and investment. Many interventions have been applied to control the COVID-19 epidemic. It seems that these measures and plans need to be assessed in the coming weeks and months to determine whether or not they have been effective. Each of these interventions started in their appropriate time during the epidemic; some of them are still in progress and some have been lifted. Nevertheless, improved public knowledge, attitude, and practice has played the most important role in controlling the COVID-19 epidemic. Future studies should take into account such interventions.

Abstract
Background and Objectives: Vaccine acceptance could seriously affect global efforts to control the Covid-19 pandemic. The aim of this study was to estimate the Covid-19 vaccine acceptance and its related factors in Tehran and Kermanshah.
Methods: A population-based cross-sectional study was conducted on 850 participants in Tehran and Kermanshah using the random digit dialing method. Multiple logistic regression was used to estimate the adjusted odds ratio of factors related to vaccine acceptance.
Results: The frequency of the Covid-19 vaccine acceptance was 66.47% (95% confidence interval: 69.57%, 63.21%). Moreover, 86.02% of the participants stated that they would use any type of (Iranian / foreign) vaccine approved by the Iranian Ministry of Health. However, 13.98% of the participants stated that they only preferred foreign approved vaccines (if available). The variables of age, fatalism, and socioeconomic status had significant associations with the Covid-19 vaccine acceptance.
Conclusion: Based on the results of this study, the Covid-19 vaccine acceptance was moderate. In order to achieve herd immunity by vaccination faster in our society, the strategy of prioritizing vaccination can be planned based on the related variables such as religious beliefs and fatalism, younger age groups, and people with higher socio-economic status that are willing to receive the vaccine.

Abstract
Background and Objectives: The Covid-19 epidemic began in Wuhan, China in the late 2019 and became a global epidemic in March 2020. In this regard, one of the most important indicators of the healthcare systems is the in-hospital mortality rate, which occurs with a time lag of one to two weeks after hospitalization. The aim of this study was to investigate the relative risk of Covid-19 mortality considering this time lag according to the number of daily hospitalizations.
Methods: The data included the number of daily hospitalizations and deaths from Covid-19 from 15 May 2020 to 10 February 2021 in Iran, which was obtained from the Github database. A log-linear distributed lag model was used to evaluate the relationship and lag effect between daily hospitalization and relative risk of death.
Results: The mean number of daily hospitalizations and deaths were 1342.2 ± 7 731.5 and 190.6 11±118.6 in the study period, respectively. It was found that an increase in the number of daily hospitalizations had a significant relationship with an increase in the relative risk of death on the same day and in the following days. As the number of hospitalizations exceeded 2000 patients per day, the cumulative relative risk of death increased to more than one.
Conclusion: The results showed that the number of hospitalizations exceeding 2000 people per day was an alert for the country's healthcare system. Overall, prevention and observance of health protocols in the first level followed by early diagnosis of the disease, improving the hospitals facilities and preparedness of healthcare staff can reduce the relative risk of death in the possible future peaks.

Abstract
Background and Objectives: The coronavirus disease 2019 (COVID-19) pandemic has raised concerns about high-risk groups in community. Due to physiologic changes in pregnancy, these women are prone to this infection; therefore, this study was conducted to evaluate Covid-19 infection and pregnancy outcomes in Qazvin Province.
Methods: This longitudinal study was done in Qazvin Province from March to October 2020. The participants included 133 pregnant women who with a definitive diagnosis of COVID-19 using CT scan and PCR test. A four-section questionnaire was used to collect demographic data, COVID-19 symptoms, and pregnancy outcomes. The mothers were followed up until six months after delivery. Data were analyzed using the SPSS software version 24 and descriptive statistics.
Results: The mean age of the mothers was 27.09 ± 5.67 years. Fever, cough, and body pain were the most common symptoms of Covid-19 in the mothers. The majority (87.96%) of the mothers were in second and third trimester of pregnancy. Maternal outcomes included preterm labor (9%), Cesarean section (51.1%) and maternal death (11.28% or 5 cases). Perinatal outcomes were abortion (6%) and fetal death (3%).
Conclusion: Based on the results of the present study, Covid-19 increased the rate of maternal mortality and preterm delivery in pregnant women. Attention should be paid to support the expecting mothers, and more emphasis should be placed on health protocols in this group of patients.

Abstract
Background and Objectives: The COVID-19 pandemic has led to major health and socioeconomic problems worldwide. This study was conducted to determine the clinical features and health behaviors related to COVID-19 in patients presenting to selected COVID-19 centers of North Khorasan University of Medical Sciences.
Methods: This cross-sectional study was carried out using stratified random sampling in 350 patients presenting to selected COVID-19 centers of North Khorasan University of Medical Sciences in August and September 2020. Demographic and clinical features and the data related to COVID-19 disease were collected using a researcher-made checklist and analyzed with the SPSS 24 software using chi-square test and logistic regression.
Results: Of 350 patients, 200 (57.1%) were male and the rest were female. The PCR test was positive in 72% of the patients. The highest percentage of infection was seen in self-employed subjects and driver, people in the age group 30-50 years, and male subjects. The highest observance of masking, hand washing, and social distancing was related to healthcare staff and the lowest was seen in self-employed people, drivers, and military staff. A history of attending a gas station increased the chance of a positive test by 2.3 times (95% CI: 1.13-4.79).
Conclusion: According to the results, age, gender, occupation and history of presence in crowded places are important determinants of infection and adherence to protocols.

Abstract
Background and Objectives: Reports indicates a higher mortality rate of Covid-19 in the elderly. A limited number of studies have been performed on elderly patients in Iran. In the present study, we investigated the clinical features and survival of elderly patients with Covid-19 in Baharloo Hospital, Tehran, Iran.
Methods: This retrospective cohort study was conducted on the data of elderly patients with Covid-19 admitted to Baharloo Hospital, Tehran, Iran. The data of the hospitalized patients were followed until discharge or death. Finally, survival-related factors were analyzed using Cox regression.
Results: A total of 522 patients were enrolled in the study, of whom 53.8% were male and 101 died. The mean age of the deceased was 76.3 years, with a standard deviation of 8.6 years. The most common clinical symptoms at the time of admission were respiratory distress (69.5%), cough (61.1%), and fever (51.1%). Cox regression results showed that the risk of death increased by 5% for each one-year increase in age. In addition, calcium supplementation reduced the risk of death by 35%.
Conclusion: The results of the present study showed that calcium supplementation could be associated with increased survival of the elderly and reduced mortality. Due to calcium insufficiency in the Iranian population and the protective role of calcium in Covid-19, this issue is essential in the elderly patients warranting further investigation in the future.

Abstract
Background and Objectives: The spread of COVID-19 in the world has had adverse effects on all aspects of people´ life and social and economic development of the communities. The current study was conducted to determine the knowledge, attitudes, and practices toward COVID-19 in the general population of Qazvin province.
Methods: This cross-sectional study conducted on 1223 people above 15 years in Qazvin province between December and January 2020. We used multistage stratified random sampling to select the participants from urban and rural health centers. The questionnaires were completed by the patients as well as through phone interviews. The questions included demographic information and knowledge, attitude, and practice toward COVID-19.
Results: In total, 1223 subjects with a mean (standard deviation) age of 35.6 ± 12.2 years participated in this study. The scores of knowledge, attitudes, and practice were 68%, 72% and 91%, respectively. The lowest score of knowledge was related to awareness of common symptoms of the disease (6%). Forty-two subjects believed they observed the principles of disease prevention. A distance of 2 meters was observed by 50.3%. The scores of knowledge (P=0.007) and practice (P=0.028) increased with age, and the scores of knowledge (P<0.001) and attitude (P=0.001) increased and decreased with an increase in the education level, respectively. Males had significantly lower knowledge (P=0.002) and practice (P<0.001) scores. Moreover, rural residents had higher attitude scores compared to urban residents (P=0.002).
Conclusion: The results suggest that the general population of Qazvin province had desirable knowledge, attitude and practice towards COVID-19 at the time of the epidemic.

Abstract
Background and Objectives: The Covid-19 prevalence can threaten self-care behaviors and disease control in people with type 2 diabetes (T2D) through increasing anxiety and stress levels and limited access to medical services. This study was conducted to investigate the association of the Covid-19 pandemic with self-care behaviors in patients with T2D.
Methods: The present study was conducted on 318 adults with T2D who participated in the Tehran Lipid and Glucose Study (TLGS) between 1397 and 1399 and completed the summary of diabetes self-care activities (SDSCA) questionnaire. Data on self-care activities during the Covid-19 pandemic were collected 3-4 months after the announcement of the epidemic in the country via telephone calls. For data analysis, a multiple linear regression model and paired t-test were used.
Results: The mean total scores of self-care behaviors were 49.7±14.8 and 56.1±13.1 before and after the Covid-19 pandemic, respectively (P<0.001). After the Covid-19 pandemic, women's total self-care score increased with an increase in the diabetes duration (β= 0.31, P= 0.020) after adjusting for the aforementioned related conditions. This score showed a significant decrease in women with a high school education compared to those with higher education (β= -6.57, P= 0.024). Moreover, the diet and foot care subscales in both sexes and the blood glucose testing score in women were significantly higher after versus before the pandemic.
Conclusion: Following the Covid-19 pandemic, self-care behaviors, especially those related to diet, foot care, and blood glucose testing, improved in the short term

Abstract
Background and Objectives: This study aimed to investigate the effective factors in the survival/hazard time of Covid-19 patients in three waves of epidemic.
Methods: All 880 Covid-19 patients were included in this prospective cohort study using the census method. Polymerase chain reaction was used to diagnose Covid-19. The survival status of these patients was followed up for 4 months. The analysis of this study was based on the time of infection in three epidemic waves in IRAN. To analyze the data, the Kaplan-Meier nonparametric approach and Cox proportional hazards regression model were used. Survival distributions were compared in three epidemic waves using the R software (version 3.6.2) (P<0.05).
Results: We diagnosed 880 positive case of Covid-19 using PCR test on 2269 susspected people who had respiratory symptomps. At the end of 1-year follow-up, cumulative incidence (risk) of Covid-19 was estimated 7%. Effective factors in the survival time of patients with Covid-19 based on Cox multivariate regression model were: 1- Age 2- Intensity of infection (Hospitalization) 3- Heart disease 4- Epidemic Wave and 5- Transmission mode of the disease (P <0.05). The Kaplan-Meier approach and log rank test (Mantel-Cox) showed a significant difference in the survival rate in three epidemic waves (P = 0.018).
Conclusion: Elderly patients, especially those with a history of heart disease, are at higher risk of death than other groups. In addition to regular screening, these patients will need active monitoring, especially at the time of hospitalization.

Abstract
Background and Objectives: COVID-19 is a new disease and little information is available on its risk factors. The aim of this study was to determine the mortality risk factors in patients with COVID-19 in the northeast of Iran.
Materials and Methods: A case-control study was conducted. Patients of both sexes with a confirmed diagnosis of Covid-19 infection who died during the study were studied as the case group and patients who were in good general health and ready for discharge were studied as the control group. Data analysis was performed with the STATA software version 14 using descriptive statistics and univariate and multiple logistic regression tests.
Results: Six hundred and eleven patients were studied (27% cases and 73% controls). Multiple logistic regression analysis showed that the odds of death were 2.8 times higher in patients over 80 years compared to patients aged 50-60 years. In addition, age under 40 years reduced the odds of mortality by 85% and living in rural areas increased odds of death by 2.2 times. Cough, general fatigue, pain, nausea and vomiting increased the odds of COVID19 survival.
Conclusion: The odds of mortality were higher in elder patients with COVID-19. In addition, living in rural areas increased the odds of mortality in patients. Cough and fatigue reduced mortality; however, it is needed to address other hidden factors for sound judgment.

Abstract
Background and Objectives: The aim of this study was to investigate the epidemiological characteristics of patients with Covid-19 in Hamadan Province.
Materials and Methods: In this descriptive cross-sectional study, demographic and epidemiological data of all people who presented to hospitals in Hamadan Province from February 2019 to December 2020 were extracted using two checklists. Data were then analyzed using the Stata software.
Results: In this study, 9674 covid-19 positive patients were examined. According to results, 49.11% of the cases occurred in the elderly over 60 years. The rate of involvement was higher in females than males (51.57% vs. 48.43%). Moreover, 72.05% of the definitive patients lived in the city and 0.76% reported traveling to areas with a high prevalence of the disease two weeks before the onset of symptoms. The highest incidence of this disease per one hundred thousand population was in Malayer, Hamedan and Nahavand counties and the highest fetality was in Razan and Dargazin, Tuyserkan and Asadabad counties, respectively. The data of suspected, probable, and definite outpatients with Covid-19 presenting to medical centers were not evaluated in this study.
Conclusion: Due to the high death rate in the elderly, males, those with underlying diseases, and people living in rural areas, it is necessary to design and apply precautionary measures in these groups. Attention should be paid to these high-risk groups in the shortest possible time to reduce the burden of this disease on individuals as well as the health care system.

Abstract
Background and Objectives: The COVID-19 epidemic and its subsequent effects have become a significant global challenge. In addition to being affected by this crisis, Iran is also facing many other problems, including sanctions and economic problems. So, there is a concern that it will suffer more severe consequences.
Methods: Scenario planning is one of the ways to recognize future changes and environmental uncertainties. This study used the so-called global business network (GBN) method, also known as the scenario matrix method. This method is based on two key uncertainties and six steps have been taken to examine variables related to health and socio-economic factors and use the opinions of relevant experts.
Results: To be expected, Iran's health system will be able to manage the epidemic in the face of various conditions with severity and weakness, and only in the pessimistic scenario or in Worst-case scenario with the default assumption of the continuation of sanctions and the spread of the epidemic. It leads to global restrictions, loss of foreign exchange reserves, loss of performance or collapse of the health system, increasing the number of deaths and diminishing the quality of life.
Conclusion: Regarding the COVID-19 epidemic and the existing background factors, scenarios of Iran’s health and economic conditions were narrated. Given the ability of the scenarios to understand the complexity and help in decision-making, it is considered a useful tool for policy makers to have a broader, comprehensive and reasonable look to achieve a correct consensus. This situation leads to the preservation and continuation of society health and conventional economic decisions.

Abstract
Background and Objectives: Faster than expected, the COVID-19 disease changed people's lives on an unprecedented scale. The present research aimed to shed light on the economic challenges of the pandemic and the efforts made concerning economic resilience. Thus, this study delved into the experience of families residing in a suburban town.
Methods: The present study was qualitative in type. It used a qualitative content analysis with a guided approach conducted through 17 in-depth semi-structured individual interviews with subjects over 15 years of age living in Tawheed Gonabad town. These subjects had lived in the area for at least three years. The interviews were held and audio-recorded in a purposive sampling method after gaining informed consent from the participants in the spring of 2021. In order to estimate the validity of the data, Lincoln and Goba's criteria were used.
Results: The economic resilience of families during the pandemic was marked by three main categories and nine sub-categories. The categories were:
1) changes to the economic dimension of the family (the sub-categories: employment, income, consumption and socioeconomic status),
2) solutions to the economic changes of the family (sub-categories: reliance on internal resources, family and receiving support from outside of the family), and
3) the effectiveness of economic resilience of families at higher levels (sub-categories: macroeconomics, family social capital and regional resilience).
As more detailed results showed, the pandemic has caused a decrease in the income and consumption of essential items in quantity and quality and imposed excessive costs on the target community. The dominant solution to economic problems has been changing consumer’s behavior and income diversification. The lack of supportive plans, poor social networks and the identity of the neighborhood are the significant barriers to the increase of economic resilience.
Conclusion: The families investigated in the present study were vulnerable in many ways and had low economic resilience. In order to improve the families' level of economic resilience, it is necessary to know the context and carry out interventions and support plans based on the families' internal and external capacities, including the neighborhood's empowering conditions.

Abstract
Background and Objectives: Serological studies are based on the detection of antibodies. However, the produced antibodies decrease over time; therefore, such methods cannot provide a valid estimate of prevalence and incidence. The present study aimed to determine the serum prevalence and cumulative incidence in the Ravansar cohort population (Youth and RaNCD Cohort) in October 2020.
Methods: A random sample of 716 people aged > 18 years old were selected from the participants in the Ravansar cohort study in October 2020. Euroimmun anti-SARS COV-2 IgG ELISA kits (Lübeck, Germany) were used to measure antibody levels. Seroprevalence was estimated with considering of cut-off = 1, and cumulative incidence (modified and modified based on test specificity) was determined using modeling.
Results: In the present study, the serum prevalence of COVID-19 viral infection in the Ravansar cohort population from 22 October 2020 to 18 November 2020 was estimated to be %35.16 (95%CI: %31.64, %38.79). Modified Cumulative incidence and modified based on test characteristics from 20 February to 18 November 2020 were estimated to be %68.85 and %67.71, respectively.
Conclusion: Although very high cumulative incidence may be a sign of approaching herd immunity, adherence to health protocols is still recommended due to the potential role of asymptomatic cases in transmitting the disease to other members of the community; and the presence of new variants of the virus and reduced antibody levels should be considered.

Abstract
Background and Objectives: COVID-19 pandemic caused a lot of severe problems in the world. This study investigated the epidemiology of the disease in Tehran in the first quarter of the epidemic's beginning.
Methods: The available information recorded for patients from 20 February 2020 to 20 May 2020 in Tehran was used. To prepare disease-related distribution maps, the addresses of patients' residences in Google Earth were called to ARC-GIS version 10-4. The methods used in GIS include IDW, Hotspot and also software development.
Results: Overall, 3699 individuals whose PCR results were positive in Tehran were included in the study. Out of the total number of them, 550 people died and the fatality rate of the disease in hospitalized patients was 14.9%. One thousand five hundred thirty patients (41.4%) have recovered, and the remaining 1619 patients were under treatment until data collection. Of the total, 1479 confirmed cases were women (40%). The average age was 57.4 years (SD=16.5). The density of cases in areas 4, 8 and 13, and the existence of some cluster diseases in neighborhoods such as Tehran Pars, Ayat and Pirouzi streets are noteworthy points.
Conclusion: The trend of the COVID-19 epidemic is dire and requires long-term measures. Nevertheless, to control this disease, the health system, the policy of isolating patients and suspicious people, wear masks especially in densely populated areas, are the most important controlling factors.

Abstract
Background and Objectives: Due to the high prevalence of COVID-19 disease and its high mortality rate, it is necessary to identify the symptoms, demographic information and underlying diseases that effectively predict COVID-19 death. Therefore, in this study, we aimed to predict the mortality behavior due to COVID-19 in Khorasan Razavi province.
Methods: This study collected data from 51, 460 patients admitted to the hospitals of Khorasan Razavi province from 25 March 2017 to 12 September 2014. Logistic regression and Neural network methods, including machine learning methods, were used to identify survivors and non-survivors caused by COVID-19.
Results: Decreased consciousness, cough, PO2 level less than 93%, age, cancer, chronic kidney diseases, fever, headache, smoking status, and chronic blood diseases are the most important predictors of death. The accuracy of the artificial neural network model was 89.90% in the test phase. Also, the sensitivity, specificity and area under the rock curve in this model are equal to 76.14%, 91.99% and 77.65%, respectively.
Conclusion: Our findings highlight the importance of some demographic information, underlying diseases, and clinical signs in predicting survivors and non-survivors of COVID-19. Also, the neural network model provided high accuracy in prediction. However, medical research in this field will lead to complementary results by using other methods of machine learning and their high power.

Abstract
Background and Objectives: Fear of COVID-19 is common among older adults and negatively impacts on their physical and mental health. Self-regulation is an essential factor for controlling or managing excitement and anxiety. So, this study aimed to determine the relationship between fear of COVID-19 and death anxiety with the moderator role of self-regulation among the elderly residing in Qazvin.
Methods: This descriptive and cross-sectional study was performed on 430 elderly aged 60 and over living in Qazvin in 2021. Samples were selected by cluster sampling method. The demographic checklist, Templer death anxiety scale, fear of COVID-19 questionnaire, and Self-Regulation Inventory were used for collecting the data. The data were analyzed using the Path Analyze test.
Results: The mean age of the elder participants in the study was 66.88 ± 6.40 years old. The results showed a significant and positive relationship between fear of COVID-19 and death anxiety (β=0.60, P<0.001) and an inverse association between fear of COVID-19 (β=-0.24, P=0.021) and death anxiety (β=-0.10, P=0.021) with self-regulation. Furthermore, the results of the Path analysis confirmed the moderator role of self-regulation in the association between fear of Covid-19 and death anxiety among the elderly residing in Qazvin, Iran.
Conclusion: Given the mediator role of self-regulation in the relationship between fear of COVID-19 and death anxiety, it is suggested to use teaching strategies to the older adults to improve self-regulation to control and mitigate the negative impacts of the fear of COVID-19 in this vulnerable population.
