The COVID-19 has placed pandemic modeling at the forefront of the whole world's public policymaking. Nonetheless, forecasting and modeling the COVID-19 medical waste with a detoxification center of the COVID-19 medical wastes remains a challenge. This work presents a Fuzzy Inference System to forecast the COVID-19 medical wastes. Then, people are divided into five categories are divided according to the symptoms of the disease into healthy people, suspicious, suspected of mild COVID-19, and suspicious of intense COVID-19. In this regard, a new fuzzy sustainable model for COVID-19 medical waste supply chain network for location and allocation decisions considering waste management is developed for the first time. The main purpose of this paper is to minimize supply chain costs, the environmental impact of medical waste, and to establish detoxification centers and control the social responsibility centers in the COVID-19 outbreak. To show the performance of the suggested model, sensitivity analysis is performed on important parameters. A real case study in Iran/Tehran is suggested to validate the proposed model. Classifying people into different groups, considering sustainability in COVID 19 medical waste supply chain network and examining new artificial intelligence methods based on TS and GOA algorithms are among the contributions of this paper. Results show that the decision-makers should use an FIS to forecast COVID-19 medical waste and employ a detoxification center of the COVID-19 medical wastes to reduce outbreaks of this pandemic.

The main purpose of this paper is to investigate the effects of COVID-19 regarding the efficiency of industries based on data in the Tehran stock market. A hybrid model of Data Envelopment Analysis (DEA) and data mining techniques is used to analyze the investment behavior in Tehran stock market. Particularly during the COVID-19 pandemic, many companies face financial crises. That is why companies with inferior performance must be benchmarked with efficient companies. First, the financial data of investments on selective companies are analyzed using data mining approaches to recognize the behavioral patterns of investors and securities. Second, customers are clustered into 3 selling and 4 buying groups using data mining techniques. Then, the efficiency of active companies in stock exchange is evaluated using input-oriented DEA. The results indicate that, among 23 industries listed on the stock market in Iran, solely nine were efficient in 2019. Moreover, in 2020, the number of efficient industries further decreased to six industries. Comparing the obtained results with those of another study which was conducted in 2018 by other researchers revealed that COVID-19 strongly affects the performance of an industry and some industries which were efficient in the past such as the bank industry became inefficient in the following year.

The Islamic Republic of Iran reported its first COVID-19 cases by 19
th February 2020, since then it has become one of the most affected countries, with more than 73,000 cases and 4,585 deaths to this date. Spatial modeling could be used to approach an understanding of structural and sociodemographic factors that have impacted COVID-19 spread at a province-level in Iran. Therefore, in the present paper, we developed a spatial statistical approach to describe how COVID-19 cases are spatially distributed and to identify significant spatial clusters of cases and how socioeconomic and climatic features of Iranian provinces might predict the number of cases. The analyses are applied to cumulative cases of the disease from February 19th to March 18th . They correspond to obtaining maps associated with quartiles for rates of COVID-19 cases smoothed through a Bayesian technique and relative risks, the calculation of global (Moran's I) and local indicators of spatial autocorrelation (LISA), both univariate and bivariate, to derive significant clustering, and the fit of a multivariate spatial lag model considering a set of variables potentially affecting the presence of the disease. We identified a cluster of provinces with significantly higher rates of COVID-19 cases around Tehran (p-value< 0.05), indicating that the COVID-19 spread within Iran was spatially correlated. Urbanized, highly connected provinces with older population structures and higher average temperatures were the most susceptible to present a higher number of COVID-19 cases (p-value < 0.05). Interestingly, literacy is a factor that is associated with a decrease in the number of cases (p-value < 0.05), which might be directly related to health literacy and compliance with public health measures. These features indicate that social distancing, protecting older adults, and vulnerable populations, as well as promoting health literacy, might be useful to reduce SARS-CoV-2 spread in Iran. One limitation of our analysis is that the most updated information we found concerning socioeconomic and climatic features is not for 2020, or even for a same year, so that the obtained associations should be interpreted with caution. Our approach could be applied to model COVID-19 outbreaks in other countries with similar characteristics or in case of an upturn in COVID-19 within Iran. Author summary: Iran was among the first countries reporting a rapid increase in the number of COVID-19 cases. Spatial epidemiology is useful to study the spatial distribution of a disease and to identify factors associated with the number of cases of such disease. By applying these methods, we aimed to identify whether there are clusters of regions in Iran with high or low number of COVID-19 cases and the association of different factors with these numbers, considering spatial relationships and maps representing these associations. Interestingly, we found regions of high number of cases and that more COVID-19 cases were present in provinces with more urbanization, aging population, number of physicians, efficient communications, and greater average temperatures, whereas less COVID-19 cases were present in provinces with more literacy. This study allowed us to understand the spatial behavior of the disease and the importance of having adequate health policies, literacy campaigns, and disseminating health information to the population.

In February 2020, the first sample test was confirmed as positive for corona virus in Masih Daneshvari Hospital that is the reference center in Iran for all pulmonary and respiratory diseases. The decisions made in a hospital or organization to manage a crisis is very vital. Success in managing any crisis requires a scientific and scholarly attitude. This paper was distilled from experiences gained in Masih Daneshvari Hospital in Tehran, capital of Iran, in March 2020 at the stubborn time of coping and managing corona virus crisis. This study was conducted using participatory action research, a methodology which identifies problems in practice, and finds methods to solve them. This Action research involves five stages: statement of the problem, planning, data interpretation and analysis, action, and evaluation of the research process during performing the study. The whole hospital was equipped for corona virus patients in 10 phases during one week and 250 active beds were equipped for these patients. Three models, namely, "corona virus crisis management model", "Pharmaceutical care management in coronavirus crisis model" and "nursing in coronavirus crisis model" were planned and implemented. During one month of implementing these three models, the supervision team monitored the accurate implementation of instructions and resolving or revising the possible deficiencies and faults. The Masih Daneshvari crisis management model in coronavirus, can be a useful and applicable model in other corona virus centers. [ABSTRACT FROM AUTHOR]

Analyzing municipal wastewater for the presence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) helps to evaluate the efficacy of treatment systems in mitigating virus-related health risks. This research investigates wastewater treatment plants' (WWTPs) performance in the reduction of SARS-CoV-2 from municipal wastewater in Tehran, Iran. SARS-CoV-2 RNA was measured within sewers, at the inlets, and after the primary and secondary treatment stages of three main WWTPs. Within sewers, the average virus titer stood at 58,600 gc/L, while at WWTP inlets, it measured 38,136 gc/L. A substantial 67% reduction in virus titer was observed at the inlets, accompanied by a 2-log reduction post-primary treatment. Remarkably, the biological treatment process resulted in complete virus elimination across all plants. Additionally, a notable positive correlation (r > 0.8) was observed between temperature and virus titer in wastewater. Using wastewater-based epidemiology (WBE) technique and the estimated SARS-CoV-2 RNA shedding rates, the infection prevalence among populations served by WWTPs found to be between 0.128% to 0.577%. In conclusion, this research not only advances our understanding of SARS-CoV-2 dynamics within wastewater treatment systems but also provides practical insights for enhancing treatment efficiency and implementing the feasibility of WBE strategies in Tehran. These implications contribute to the broader efforts to protect public health and mitigate the impact of future viral outbreaks. [ABSTRACT FROM AUTHOR]

Introduction: The COVID-19 pandemic posed significant risks to children worldwide. This study aimed to assess the COVID-19 protection status of children and explored the relationship between household socio-economic status and COVID-19 morbidity and preventive measures, including vaccination and mask-wearing, in two cities in Iran. Method: A population-based cross-sectional study was conducted from July to October 2022 among 7 to 18-year-old children and their families in Tehran and Karaj. A total of 3,022 samples were selected using stratified multistage cluster sampling. Data were collected through interviews with children and adults, using questionnaires and was analyzed with Stata software version 14. Results: The analysis focused on 2,878 children with a median age of 12. Over half (54%) reported that the pandemic negatively affected their family's financial status, with 45% describing its impact on children's needs as negative or very negative. Just under 50% of respondents consistently wore masks during the study period, and around 54% had received at least one dose of the COVID-19 vaccine. Reasons for not getting vaccinated included concerns about side effects, ineligibility for the target age group, and overcrowding at vaccination sites. The odds of not getting vaccinated were significantly lower for children aged 15–18, with boys more likely to refuse vaccination than girls. Conclusion: The financial impact of the pandemic in Iran affected families' ability to meet their children's needs. Moreover, low vaccination acceptance rates increased children's vulnerability to health problems and contributed to COVID-19 infections. Efforts should be made to increase vaccination acceptance, particularly among immigrant populations. [ABSTRACT FROM AUTHOR]

Background: Perceived social support (PSS) plays a considerable role in mental health. The Multidimensional Scale of Perceived Social Support (MSPSS) is one of the most widely used scales, leading to much research evidence. The present study investigated its measurement model, equivalence across gender (male and female) and age groups (older patients= above 60 and non-older patients= below 60), and concurrent validity. Methods: A cross-sectional survey was conducted between March and October 2020, on patients hospitalized due to COVID-19 in Tehran, Iran. The scales were administered to 328 COVID-19 patients (54.6% male, aged 21 to 92) from two general hospitals; participants completed MSPSS (including friends, family, and significant others subscales), Pittsburgh Sleep Quality Index (PSQI, include sleep latency, subjective sleep quality, habitual sleep efficiency, sleep duration, use of sleep medication, daytime dysfunction, and sleep disturbances subscales), and the Perceived Stress Scale-10 (PSS-10, to assess patients' appraisal of stressful conditions). Results: The MSPSS three-factor structure was confirmed among COVID-19 patients by Confirmatory Factor Analysis (CFA). The results support the MSPSS internal consistency and configural, metric, and scalar invariance across gender and age groups. Nevertheless, small but significant differences were found across ages based on the latent factor mean of the MSPSS from friends, with a lower mean level in older patients. The coefficients of Cronbach's alpha (ranging from.92 to.96), the ordinal theta (ranging from.95 to.98), and Omega (ranging from.93 to.97) suggested high internal consistency of MSPSS. The concurrent validity of MSPSS was evidenced by its significant negative correlation with PSS-10 (Γ
b = -.13, p <.01) and also subjective sleep quality (Γb = -.22, p <.01), sleep disturbances (Γb = -.26, p <.001), and daytime dysfunction (Γb = -.26, p <.001). Conclusions: The MSPSS was valid and reliable for measuring individuals' perception of social support between males and females and older and non-older COVID-19 patients.

Background: Vaccination is one of the most effective ways to manage infectious disease epidemics such as Covid-19. However, the low rates of vaccination in populations at risk including people using illicit substances, hinders the effectiveness of preventive vaccines in reducing transmission. The aim of this study was to investigate the rate of Covid-19 vaccination and its related factors among people who use substances in Tehran, Iran. Methods: Between July and December 2022, 386 people who use substances aged ≥ 18 years old were recruited by convenience street-based sampling in Tehran. The outcome variable in this study was self-reported completion of at least two doses of the Covid-19 vaccine. Logistic regression was used to investigate the factors related to Covid-19 vaccination. Data were analyzed using SPSS software version 20 at the 0.05 level of significance. As a measure of risk, 95% Confidence interval (CI) was used. The level of significance was considered at 0.05. Results: Almost three-quarters (n = 286) of the participants reported receiving at least two doses of the Covid-19 vaccine (95% CI, 70.2–79.3). Those participants with high school diplomas were 1.17 times more likely than less educated participants to report having had 2 vaccinations (OR of 1.17, CI 95%: 1.03–1.81). Participants with a higher mean score of having a positive attitude towards Covid-19 vaccination were more likely to have received a vaccination (OR of 1.12, CI 95%: 1.08–1.17). Ethnicity was also an influential variable, people with non-Fars ethnicity were less likely to be vaccinated than those of Fars ethnicity (OR of 0.33, CI 95%: 0.13–0.81). People with higher-than-average monthly income were more likely to report vaccination than those with low monthly incomes (OR of 1.27, CI 95%: 1.09–1.8). Also, participants reporting less access to vaccination centers had a lower chance of reporting having been vaccinated than those who reported high access to vaccination centers (OR of.17, CI 95%:.08-.36). Conclusions: Covid-19 vaccine uptake was found to be relatively high among people using illicit substances in this study. Higher levels of education, Fars ethnicity, higher income levels, having a positive attitude towards vaccination and access to vaccination centers were the most important predictors of Covid-19 vaccination in this study.

The present study was done to evaluate the prevalence of intestinal parasitic infections (IPIs) in patients with COVID-19 in health care centers (Imam Reza and Golestan hospitals), Tehran, capital of Iran. By designing a matched case-control study, 200 fecal samples were collected for each of the COVID-19 patients and healthy individuals. Nasopharyngeal/oropharyngeal swab samples were collected from all participants for the diagnosis of COVID-19. RNA extraction was performed, and then real time reverse-transcription polymerase chain reaction (rRT-PCR) assay was applied to detect viral RNA. Considering the lung complications, 25%> lung complications was detected in 49 patients, 25–49% in 42 patients, and 50%≤ in 109 patients. Fecal samples were examined using different parasitological techniques. After nested-PCR, sequencing was applied to identify Cryptosporidium spp. and microsporidia spp. A relatively lower prevalence of IPIs was detected among control group (7.5%), than in COVID-19 patients (13%), though not significant P = 0.13 . The most prevalent parasite among patients was Blastocystis sp. (6%). Also, 13.76% of IPIs were detected in inpatients with more than 50% lung complication. As well, a remarkably significant difference in IPIs was observed among diarrheic COVID-19 patients, in comparison with nondiarrheic patients P < 0.00001 . Moreover, the isolated sequences in the present study belonged to C. parvum subtype IIa and Enterocytozoon bieneusi genotypes D and Peru 8. In conclusion, more epidemiological and clinical research studies are needed to better understand the status and interaction of IPI in COVID-19 in Iran and other countries. [ABSTRACT FROM AUTHOR]

With the severe outbreak of the novel coronavirus (COVID-19), researchers are motivated to develop efficient methods to face related issues. The present study aims to design a resilient health system to offer medical services to COVID-19 patients and prevent further disease outbreaks by social distancing, resiliency, cost, and commuting distance as decisive factors. It incorporated three novel resiliency measures (i.e., health facility criticality, patient dissatisfaction level, and dispersion of suspicious people) to promote the designed health network against potential infectious disease threats. Also, it introduced a novel hybrid uncertainty programming to resolve a mixed degree of the inherent uncertainty in the multi-objective problem, and it adopted an interactive fuzzy approach to address it. The actual data obtained from a case study in Tehran province in Iran proved the strong performance of the presented model. The findings show that the optimum use of medical centers' potential and the corresponding decisions result in a more resilient health system and cost reduction. A further outbreak of the COVID-19 pandemic is also prevented by shortening the commuting distance for patients and avoiding the increasing congestion in the medical centers. Also, the managerial insights show that establishing and evenly distributing camps and quarantine stations within the community and designing an efficient network for patients with different symptoms result in the optimum use of the potential capacity of medical centers and a decrease in the rate of bed shortage in the hospitals. Another insight drawn is that an efficient allocation of the suspect and definite cases to the nearest screening and care centers makes it possible to prevent the disease carriers from commuting within the community and increase the coronavirus transmission rate.

Background: Recent studies have reported that the increase in the pro-oxidant-antioxidant balance (PAB) in patients with COVID-19 is associated with the exacerbation of clinical manifestations of the disease. The underlying risk factors of these patients, including a history of chronic systemic diseases, also may be associated with PAB disorder. It seems that there should be a significant relationship between clinical disorders and laboratory factors with PAB disorder. This issue was evaluated in this study. Methods: In this cross-sectional study, 105 patients referred to Masih Hospital in Tehran in 2021, including 58 subjects with COVID-19 infection and 47 as a control group, were studied. The subjects in this study were evaluated for PAB by the ELISA method. Results: The mean value of PAB in individuals with and without COVID-19 was 72.77±17.66 and 66.53±14.30, respectively, which was significantly higher in COVID-19 patients (P=0.049). In patients with COVID-19, there was a significant correlation between PAB and plasma triglyceride level (P=0.011) and an inverse relationship between PAB level and blood sodium level (P=0.047). In the COVID-19 group, there was no significant relationship between PAB level and histories of hypertension, hyperlipidemia, diabetes, and ischemic heart disease. Conclusion: The increase in PAB is quite evident in patients with COVID-19 compared to healthy individuals. There is a significant relationship between PAB and some laboratory markers in these patients such as blood triglyceride levels as well as decreased serum sodium. Therefore, it still seems that the activity of oxidative stress processes plays a role in the pathogenesis and exacerbation of COVID-19 disease and can be considered one of the therapeutic goals in these patients.

Background: Coronavirus disease 2019 (COVID-19) is a multisystem disease, manifested by several symptoms of various degrees. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can affect the central nervous system (CNS) through several mechanisms and brain imaging plays an essential role in the diagnosis and evaluation of the neurological involvement of COVID-19. Moreover, brain imaging of patients with COVID-19 would result in a better understanding of SARS-CoV-2 neuropathophysiology. In this study, we evaluated the brain imaging findings of patients with COVID-19 in Shohada-e Tajrish Hospital, Tehran, Iran. Methods: This was a single-center, retrospective, and observational study. The hospital records and chest and brain computed tomography (CT) scans of patients with confirmed COVID-19 were reviewed. Results: 161 patients were included in this study (39.1% women, mean age: 60.84). Thirteen patients (8%) had ischemic strokes identified by brain CT. Subdural hematoma, subdural effusion, and subarachnoid hemorrhage were confirmed in three patients. Furthermore, there were four cases of intracranial hemorrhage (ICH) and intraventricular hemorrhage (IVH). [ABSTRACT FROM AUTHOR]

The decision to perform tracheostomy during the COVID-19 pandemic has been based mainly on practical and empirical standards. Also, the amount of scientific evidence to determine the exact timing of tracheostomy in patients with severe COVID-19 on mechanical ventilation is not significant. We conducted a retrospective cohort study on mechanically ventilated COVID-19 patients from April 25, 2021 to January 25, 2022 in intensive care units of Imam Khomeini Hospital Complex, Tehran, Iran. The 30-day survival of patients was calculated and compared between patients under tracheostomy and those without tracheostomy. A number of 135 COVID-19 cases (75 patients in the intubated group and 60 patients in the tracheostomy group) were included in this study. The mean age of the population was 53.6±12.4. The overall mortality rate was 101 (74.8%). The 30-day mortality rate was significantly higher in the intubated group (90.6%) than in the tracheostomy group (55%) (P< 0.001). The mortality rate was 60% in the early (= 7 days) tracheostomy group and 50% in the late (>7 days) group. This difference was not statistically significant (P> 0.05). Tracheostomy is a preferred method in airway management of severe COVID-19 patients under mechanical ventilation; however, early tracheostomy during the first week of intubation may not be superior to late tracheostomy in decreasing the mortality rate.

Background: The evidence on the psychological consequences of coronavirus 2019 mainly relates to general psychiatric problems, and a few studies have reported the incidence and predictors of obsessive-compulsive disorder. Objective: To determine the prevalence of obsessive-compulsive disorder (OCD) and its predictors in Iranian COVID − 19 recovered individuals at 3–6 months, 6–12 months, and 12–18 months after recovery. Method: In this cross-sectional analytical study, 300 participants were randomly selected based on the inclusion criteria from three hospitals in three different regions of Tehran, Iran, and were assessed by the Clinical Demographic Information Questionnaire, the Obsessive Compulsive Inventory-Revised (OCI-R), the Depression, Anxiety and Stress Scale 21 (DASS21), The Pittsburgh Sleep Quality Index (PSQI) and Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5). The obtained data were analyzed with SPSS version 26. Results: The results showed that the mean score of OCD is 30.58 ± 15.22, with a prevalence of 71% (n = 213). Female gender (BF = 0.50, p = 0.01), sleep disturbance (BF = 0.02, p = 0.001), PTSD (BF = 0.009, p = 0.0001), depression (BF = 0.0001, p = 0.0001), and stress (BF = 0.0001, p = 0.001) are the strongest predictors of the presence of OCD in recovered COVID − 19 individuals. Conclusion: OCD-like symptoms was observed in the majority of COVID − 19 recovered individuals with mild to moderate severity. In addition, the stated prevalence, severity, and significance varied according to sociodemographic and health inequalities. [ABSTRACT FROM AUTHOR]

Background: Fear of relapse and re-infection during the coronavirus disease 2019 (COVID-19) pandemic can affect people with chronic relapsing diseases, such as multiple sclerosis (MS). We evaluated fear of reinfection, anxiety, and relapse during the COVID-19 pandemic in Iranian people with MS. Methods: This multicenter, cross-sectional study was performed in the MS clinic of Sina Hospital, Tehran, Iran, and Hakim Private Hospital, Isfahan, Iran, between January and April 2022. We asked the participants to fill out validated Persian versions of Fear of Relapse Scale (FoR), and Beck Anxiety Inventory (BAI) questionnaires and answer a binary question about their fear of getting reinfected with COVID-19. Results were reported as mean ± standard deviation (SD) for continuous variables or frequencies for categorical variables. For continuous variables which did not have a normal distribution, we reported the median and interquartile range (IQR). Spearman correlation coefficient between anxiety score and FoR score was calculated. An independent samples ttest was used to compare continuous variables. Results: Three hundred and sixty-eight patients participated in this study. The median scores of FoR and BAI were 49.7 and 34.3, respectively. Fifty-three had new relapses in their last infection.

Background: The impacts of caring for hospitalized COVID-19 patients on nurses are wide and varied and have not been comprehensively explained in the existing literature. The aim of this study was to explore the nurses' perception of the impacts of caring for hospitalized COVID-19 patients. Materials and Methods: In this qualitative descriptive study, data were collected via semi-structured interviews with 20 nurses and head nurses of emergency/internal wards and Intensive Care Units (ICUs) of 2 hospitals in Tehran, Iran. The purposive sampling method was used, and data analysis was performed using a conventional content analysis approach. Results: After data analysis, 12 subcategories, 3 main categories, and 1 theme (professional resilience) were extracted. The three main categories included "complex care," "professional development," and "caring self-efficacy." Caring for hospitalized COVID-19 patients was complex for nurses; however, the care provided to these patients could also lead to the nurses' professional development and caring self-efficacy. Conclusions: Health organizations and nursing managers can better manage the COVID-19 pandemic and other similar future crises through strategies such as providing nurses with adequate and diverse resources and facilities, encouraging and supporting nurses in various dimensions, providing positive media advertisements for the nursing profession and nurses, and providing nurses with necessary and applicable knowledge and skills.

Background and Aim: Telemedicine can be considered a primary modality of patient care for non-emergent conditions in the COVID-19 era. The usage and expansion of telemedicine are important and inevitable issues. We decided to investigate the neurosurgeons' perspective on telemedicine in the treatment and follow-up of neurosurgical patients during the COVID-19 period. Methods and Materials/Patients: This cross-sectional study was carried out in the Department of Neurosurgery, Tehran, from June 2021 to July 2021. An internet-based questionnaire was distributed among all postgraduate and assistant neurosurgeons at the Tehran University of Medical Sciences. Statistical analysis was performed using SPSS software, Version 24.0 (IBM SPSS statistics for windows, IBM corp; 2016). Results: This study was performed among 74 neurosurgeons who were mainly male (89.2%). Their mean age was 33.16±5.69 years (ranging from 27 to 62 years), and telemedicine has not been used previously in 37 precipitants (50%). Most precipitants preferred telemedicine for follow-up (93.24%). The common reasons for unimplemented telemedicine were determined by insurance and repayment obstacles (58.11%). Most of the participants believed that telemedicine should first be adapted to working condition and local setting, then it can be applied more in the future. Eventually, the effectiveness of telemedicine was controversial, according to most neurosurgeons' replies. Conclusion: This study indicated neurosurgeons' preference for telemedicine. They considered it a comfortable alternative. However, the effectiveness of telemedicine is controversial as it should be adapted first and then used extensively for future purposes. It is also suggested that future studies compare the results of this research with those of studies performed after the COVID-19 outbreak. [ABSTRACT FROM AUTHOR]

Background and Aim: Coronavirus is an infectious disease that is now known as an epidemic, early and accurate diagnosis helps the patient receive more care. The aim of this study is to investigate Covid‐19 using blood tests and multilayer perceptron neural network and affective factors in improving and preventing Covid‐19. Methods: This cross‐sectional study was performed on 200 patients referred to Sina Hospital, Tehran, Iran, who were confirmed cases of Covid‐19 by computerized tomography‐scan analysis between 2 March 2020 to 5 April 2020. After verification of lung involvement, blood sampling was done to separate the sera for C‐reactive protein (CRP), magnesium (Mg), lymphocyte percentage, and vitamin D analysis in healthy and unhealthy people. Blood samples from healthy and sick people were applied to the multilayer perceptron network for 70% of the data for training and 30% for testing. Result: By examining the features, it was found that in patients with Covid‐19, there was a significant relationship between increased CRP and decreased lymphocyte levels, and increased Mg (p < 0.01). In these patients, the amount of CRP and Mg in women and the number of lymphocytes and vitamin D in men were significantly higher (p < 0.01). Conclusion: The important advantage of using a multilayer perceptron neural network is to speed up the diagnosis and treatment. [ABSTRACT FROM AUTHOR]

In light of the coronavirus disease 2019 (COVID-19) pandemic, there is a strong correlation between citizens' social responsibility (SR) and sustainable development (SD). Accordingly, the present study aimed to model the impact of citizens' SR on SD concerning the modifying role of the COVID-19 pandemic. To this end, the data were collected from two target groups, namely, elites (viz. experts and professionals) (n=15) and the citizens of Tehran, Iran (n=384), through a questionnaire. The research model was also designed based on expert opinions, using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), type-II fuzzy logic, and ELECTRE III, and then modified. The given model was subsequently examined by the partial least squares regression (PLS regression). Results showed that if citizens' SR is elevated by about one-unit, social justice, sustainable economy, and stable environment would be augmented by 0.693, 0.735, and 0.583 units, respectively. SD would also grow by 0.485, 0.948, and 0.743 units if social justice, sustainable economy, and sustainable environment increased by one unit. Consequently, the results of the present study confirm the mechanism of the impact of citizens' SR on SD. [ABSTRACT FROM AUTHOR]

Background: It seems that patients with multiple sclerosis (MS) are at a higher risk for coronavirus disease 2019 (COVID-19) implications due to being subjected to immunomodulatory or immunosuppressive treatments. Besides, obesity as a risk factor may lead to more adverse consequences. The relationship between obesity and COVID-19 morbidity and outcomes in Iranian patients with MS still remains unclear. Methods: A cross-sectional study was conducted in Sina Hospital, Tehran, Iran. Patients with MS were asked to complete an online questionnaire in the Google Form format. Demographic information, clinical information including MS disease-related factors, COVID-19-related factors, and anthropometric information were recorded. Totally, 492 patients filled the questionnaire during two weeks in November 2021, by the response rate of 21.6%. Body mass index (BMI) was categorized based on the standard classification of the World Health Organization (WHO). The logistic regression was used to examine the risk of morbidity and chi-square test/one-way analysis of variance (ANOVA) was employed to determine the difference regarding severity and symptoms among groups. Results: In the fully adjusted model, the odds ratio (OR) of COVID-19 morbidity in class II obese participants was significantly 5.41 times higher than that in the normal BMI group [OR: 5.41, 95% confidence interval (CI): 1.00-29.09]. COVID-19 severity was significantly different among BMI groups (P = 0.024). Respiratory symptoms (P = 0.05) as well as gastrointestinal (GI) symptoms (P < 0.01) of COVID-19 were more prevalent among class I and class II obese patients compared with overweight, normal weight, and underweight groups. Moreover, no one in the class I and class II obesity groups reported COVID-19 morbidity without any symptoms (P = 0.04). Conclusion: The results of the current study support the view that obesity could play a key role in susceptibility to COVID-19 morbidity and severity of the symptoms in patients with MS. The findings recommended that neurologists pay more attention to patients' BMI during this pandemic. [ABSTRACT FROM AUTHOR]

Background: The medium and long-term problems of COVID-19 survivors after hospital discharge are currently unknown, but new evidence is emerging. This study was conducted with the aim of the effectiveness of mindfulness-based cognitive therapy (MBCT) on resilience and psychological distress of recovered patients from COVID-19 in Tehran City, Iran, in 2021. Methods: The study was a quasi-experimental type of pre-test-post-test design with a control group with a 2-month follow-up. The statistical population included all patients 25-55 years in Tehran City in 2021 with 4 to 8 weeks of discharge. The sample included 30 people who recovered from COVID-19 who had symptoms of depression, anxiety, and stress (based on [depression, anxiety and stress scale] DASS-21 scores) and was selected by purposive sampling and based on the inclusion criteria, and then matching assigned to an experimental (MBCT) and a control group (n=15each). The experimental group received 8 sessions of 60 minutes of mindfulness-based cognitive therapy (individual and online) but the control group received no intervention. The research tools were the DASS21 and Connor-Davidson resilience scale (CD-RISC). Data were analyzed using a mixed analysis test and Ben Foroni post hoc test using SPSS version 23 software. Results: The results showed that MBCT in the post-test positively affected the resilience (F=30.31, P=0.001) and negatively affected the psychological distress (F=120.70, P=0.001) of those who Recovered from COVID-19. This therapeutic effect continued until the follow-up phase. According to the results, MBCT is effective in increasing resilience and reducing psychological distress and a significant difference is observed between the experimental and control groups (P=0.01). Conclusion: Based on the findings, MBCT is effective in increasing resilience and reducing psychological distress after illness and the use of this model can be useful in the psychological rehabilitation of those who have recovered from COVID-19.

Background: Covid-19 is a life-threatening disease-causing and accompanying multiple organ injuries in hospitalized patients. Case presentation: A 73-year-old male patient was admitted to a hospital in Tehran province. He had symptoms of COVID-19 disease, and his involvement with COVID-19 was confirmed by the molecular method and patchy areas of ground-glass opacities in the computed tomography (CT) scan. He was under treatment for his diabetes and hypertension. After a few hours of admission, he had low oxygen saturation (80%); hence he became under intensive care, oxygen, and anticoagulant therapy. On day 6 of ICU admission, his clinical status became worse when he had left side pain, hematuria, glucosuria, proteinuria, and high serum creatinine level (3.28 mg/dL). CT scan imaging was indicating of renal hematoma. The surgical or any invasive intervention was impossible due to the unstable status of the patient. Packed red cell and plasma replacement therapy were not effective in the prevention of expiration of the patient on day 7 of hospitalization. Spontaneous renal hemorrhage concurrent with COVID-19 disease was the definite diagnosis for this case. Conclusion: We think that COVID-19 involvement may accelerate renal injury in our case. Anyhow, there were multiple predisposing risk factors for renal hematoma, in this case, such as diabetes, anticoagulant therapy, and COVID-19. We suggest that COVID-19 involvement accelerates renal problems. Nevertheless, this conclusion should be confirmed by other reports and research by clinical scientists. [ABSTRACT FROM AUTHOR]

Background: It remains crucial to understand socio-demographic determinants of COVID-19 infection to improve access to care and recovery rates from the disease. This study aimed to investigate the urban and sub-urban disparities associated with COVID-19 in patients visiting healthcare facilities in the province of Tehran, Iran.Methods: Data from 234 418 patients who were diagnosed with COVID-19 infection from March 2020 to March 2021 in the province of Tehran were used in this analysis. Descriptive statistics were used to describe the characteristics of the study population. Chi-Squared test was applied to examine the association of study variables with residing area. Independent samples t-test was performed to compare mean age of patients in urban and sub-urban areas. Multiple Logistic Regression model was applied to examine the association of study variables with disease outcome.Results: Overall, most patients resided in the urban settings (73%). Mean age of patients was significantly lower in sub-urban areas compared to their counterparts in urban settings (49 ± 23.1 years versus 53 ± 21.1 years, P < 0.001). Positive PCR test results were more common in urban areas (48.5% versus 41.3%, P < 0.001). Yet, sub-urban settings had higher rates of positive chest CT scan reports (62.8% versus 53.4%, P < 0.001). After accounting for age and sex covariates, residing in urban areas was associated with higher likelihood of being admitted to an ICU (OR = 1.27, CI: 1.240-1.305). Yet, a greater vulnerability to fatal outcome of COVID-19 infection was shown in patients living in sub-urban areas (OR = 1.13, CI: 1.105-1.175).Conclusions: This study revealed a clear disparity in the health outcome of patients infected with COVID-19 between urban and sub-urban areas.

By applying multivariate regression to 2020 survey data from four Tehran hospitals, we measure eight recognized sources of Coronavirus disease 2019 (COVID-19) pandemic-related anxiety among 723 healthcare workers (HCWs) with diverse sociodemographic characteristics employed across different hospital areas and positions. The most prominent anxiety source identified is the risk of workplace COVID-19 contraction and transmission to family, followed by uncertainty about organizational support for personal and family needs in the event of worker infection. A supplemental qualitative analysis of 68 respondents in the largest hospital identifies four additional anxiety sources, namely, health, finances, workload, and leadership. This evidence of the multifaceted nature of anxiety sources among HCWs highlights the differentiated approaches that hospital policymakers must take to combat anxiety. [ABSTRACT FROM AUTHOR]

Background:There were no documents about the non-lung involvement of COVID-19, even in the absence of lung involvement. The present study aimed to report a single-centre experience of liver involvement caused by COVID-19 disease in Iran. MaterialsandMethods:We recorded information of 120 patients who suffered COVID-19 disease, and they were admitted to the intensive care unit at Taleghani hospital in Tehran, Iran, between March and May 2020. Along with clinical and diagnostic parameters, the outcome of patients concerning improvement, disease progression or death was also assessed. Results:In total, 68 patients (56.7%) had abnormal liver dysfunction. The most common changes in liverrelated parameters were elevated international normalized ratio (INR) (mean serum level of 2.5) followed by elevated alkaline phosphatase (ALP) (mean serum level of 412 mg/dl). The mean level of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased 4 and 9 times more than the standard limit. The overall death rate in COVID-19 patients was 38 patients (55.88%, n=68). Conclusion:Liver injuries are common findings in patients suffering COVID-19 infection and leading to poorer outcomes. Serum bilirubin level of more than 3mg/dl was associated with higher mortality in patients with liver damage. [ABSTRACT FROM AUTHOR]

The restaurant business has turned into a dynamic and ever‐growing industry. So, food safety must be a priority for these establishments, especially during the COVID‐19 pandemic. The aim of this study was to determine the effect of training intervention on the health and food safety knowledge, attitude, and self‐reported practice (KAP) of restaurant food handlers during the COVID‐19 pandemic. This quasi‐experimental study was conducted on 159 restaurant food handlers in Tehran, Iran. The training intervention was developed based on the latest global guidelines. The KAP of the subjects was measured before and after the training. Fisher's exact test, paired t test, and repeated measures ANOVA were used for statistical analysis. Data analysis was done using the IBM_SPSS software. The total knowledge scores of participants were low (17.6%), moderate (35.2%), and good (47.2%) before training, which were changed to 5% (low), 23.9% (moderate), and 71.1% (good) after training. The total pretraining attitude scores were 0.6, 77.4, 18.2, and 3.8% that were changed to 0% (strongly negative), 49.1% (negative), 33.3% (positive), and 17.6% (strongly positive), respectively. Also, the self‐reported practice scores of the participants before training were 1.3, 56, and 42.7 that were changed to 0% (weak), 26.4% (acceptable), and 73.6% (desirable) after the intervention, respectively. Paired t test results showed a statistically significant increase in all scores. The interaction of training with age and education was statistically significant in increasing the knowledge and attitude scores of the participants by the repeated measures ANOVA. Improving the KAP of food handlers by health and food safety training can improve the status of restaurants and minimize the outbreak of pandemic diseases, including COVID‐19, which is an effective step in community health. Thus, it is an urgent need for policymakers to design an online system of continuous food safety training for food handlers. [ABSTRACT FROM AUTHOR]

Background: Defining socio-demographic factors, clinical presentations and underlying diseases associated with COVID-19 severity could be helpful in its management. This study aimed to further clarify the determinants and clinical risk factors of the disease severity in patients infected with COVID-19.Methods: A multi-centre descriptive study on all patients who have been diagnosed with COVID-19 in the province of Tehran from March 2020 up to Dec 2020 was conducted. Data on socio-demographic characteristics, clinical presentations, comorbidities, and the health outcomes of 205,654 patients were examined. Characteristics of the study population were described. To assess the association of study variables with the disease severity, the Chi-Squared test and Multiple Logistic Regression model were applied.Results: The mean age of the study population was 52.8 years and 93,612 (45.5%) were women. About half of the patients have presented with low levels of blood oxygen saturation. The ICU admission rate was 17.8% and the overall mortality rate was 10.0%. Older age, male sex, comorbidities including hypertension, cancer, chronic respiratory diseases other than asthma, chronic liver diseases, chronic kidney diseases, chronic neurological disorders, and HIV/AIDS infection were risk markers of poor health outcome. Clinical presentations related with worse prognosis included fever, difficulty breathing, impaired consciousness, and cutaneous manifestations.Conclusion: These results might alert physicians to pay attention to determinants and risk factors associated with poor prognosis in patients with COVID-19. In addition, our findings aid decision makers to emphasise on vulnerable groups in the public health strategies that aim at preventing the spread of the disease and its mortalities.

The potential of mitigating the spreading rate and consequences of the coronavirus disease 2019 (COVID-19) currently depends on adherence to sanitary protocols (e.g., hand hygiene and social distancing). The current study aimed to investigate the role of fatalism and comparative optimism for adherence to COVID-19 protocols. We also tested whether these factors are directly associated with adherence or associated through attitudinal mediation. The results were based on a web survey conducted among university students (n = 370) in Tehran, Iran. The respondents completed a multidimensional measure of fatalism (general fatalism, internality, and luck) and measures of comparative optimism, attitudes toward COVID-19 health measures, and adherence. The estimated structural equation model explained approximately 40% of the total variance in attitudes toward COVID-19 protocols and adherence. As expected, high internality was associated with stronger adherence, whereas luck was associated with weaker adherence. Comparative optimism was more strongly associated with adherence than fatalism, and somewhat unexpectedly comparative optimism was associated with stronger adherence. Analyses of direct and indirect effects suggested that fatalism was mainly mediated through attitudes, whereas comparative optimism had both direct and mediated effects. The findings are discussed in relation to the role of these social psychological factors for COVID-19 mitigation. [ABSTRACT FROM AUTHOR]

Background: COVID-19 was declared a pandemic on March 11, 2020. Given that the severe shortage of hospital beds has led to early discharge and insufficient patient education on home care routines and isolation protocols, the close follow-up of patients and their immediate relatives is an integral part of transitioning from hospital care to home care for patients with COVID-19. Objective: We designed the Tele-COVID-19 prospective cohort to follow-up with COVID-19 patients in Tehran, Iran, and improve health care delivery and the recording of postdischarge patients' clinical profiles. Methods: All adult patients who were admitted to the COVID-19 wards of teaching hospitals in Tehran, Iran were eligible to participate in this cohort study. At baseline, patients were recruited from 4 major hospitals from March 9, 2020 to May 20, 2020. Telephone follow-ups, which were led by volunteer medical students, were conducted on postdischarge days 1-3, 5, 7, 10, and 14. We collected data on a range of sociodemographic, epidemiological, and clinical characteristics by using a standard questionnaire. Results: Of the 950 patients with confirmed COVID-19 who were approached, 823 (response rate: 86.6%) consented and were enrolled into the cohort. Of the 823 participants, 449 (54.5%) were male. The mean age of participants was 50.1 years (SD 12.6 years). During the initial data collection phase, more than 5000 phone calls were made and over 577 reports of critical patients who were in need of urgent medical attention were recorded. Conclusions: The Tele-COVID-19 cohort will provide patients with sufficient education on home care and isolation, and medical advice on care and the proper use of drugs. In addition, by preventing unnecessary hospital returns and providing information on household SARS-CoV-2 transmission as early as possible, this cohort will help with effective disease management in resource-limited settings.

COVID-19 ,REVERSE transcriptase polymerase chain reaction ,COMPUTED tomography ,COVID-19 testing - Abstract
Background & Objective: Diagnosis of coronavirus disease 2019 (COVID-19) can be challenging, especially when the real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) is not available or it is negative. In this study, we evaluated imaging and laboratory findings in a group of patients with a multidisciplinary diagnosis of COVID-19 pneumonia. Methods: A total of 163 patients with a clinical diagnosis of COVID-19 pneumonia admitted to a specialised respiratory centre in Tehran, Iran were enrolled in this study. The distribution and characteristics of presenting radiological and laboratory findings were evaluated and the relationship to the outcome was investigated. Results: RTPCR was positive in 92 patients. The diagnosis of COVID-19 in RTPCR negative patients was made on clinical and radiological features (n=71) and 24 (14.7%) patients died of disease. The common computed tomography (CT) scan findings included ground-glass (94%) and consolidating opacification (12%), mainly in the lower lobes (90%). Peripheral and central lung changes were observed in 90% and 52% of patients, respectively. Lymphopenia, positive CRP, and raised LDH were present in 32%, 65%, and 96% of cases, respectively. A raised LDH of >500U/L was the best predictor of death in these patients (R2=0.6623; OR=24.4). Other markers of outcome included male gender, age (>50 years), lymphopenia, and severe CXR changes. Conclusion: Diagnosis of COVID-19 can be challenging, and a multidisciplinary approach is often needed. Whilst RT-PCR is still the standard diagnostic test, a negative test should be interpreted with caution. Blood tests and imaging can be useful in the diagnosis, monitoring, and risk assessment in patients with COVID-19. [ABSTRACT FROM AUTHOR]

During the last months of the coronavirus pandemic, with all those public restrictions and health interventions, the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appears now to have been raised in some countries around the world. Iran was one of those first countries facing the second wave of coronavirus, due to the lack of appropriate public restrictions because of economic problems the country is facing. The clinical and demographic characteristics of severe cases and non-severe cases of Coronavirus Disease (COVID-19) in 192 patients in Tehran, Iran, between June 16 and July 11, 2020, were investigated. The patients were divided into severe cases (n = 82) and non-severe cases (n = 110). Demographic and clinical characteristics were compared between the two study clusters. The mean age was 54.6 ± 17.2 years, and the most common presenting symptom was persistent cough (81.8%) and fever (79.7%). The logistic regression model revealed that age, BMI, and affected family members were statistically associated with severity. Patients with complicated conditions of disorders faced more hospitalization days and medical care than the average statistical data. As the coronavirus spike in the case and death reports from June 2020, we observed the rise in the incidence of severe cases, where 42.7% (82/192) of cases have resulted in severe conditions. Our findings also suggested that the effect of IFB (Betamethasone) was more valid than the other alternative drugs such as LPV/r and IVIg. [ABSTRACT FROM AUTHOR]

Introduction: During the Coronavirus Disease 2019 (COVID-19) outbreak, news media has played an important role in informing people to satisfy their curiosity about this stressful condition. Regular exposure to such stressful news may elicit different emotions in people and engage them in using strategies to control their emotions. In the present study, we aimed at exploring the most common negative emotion(s) experienced by individuals, as well as the most frequent Emotion Regulation (ER) strategies used facing the COVID-19-related news. We also examined whether the variable of personal relevance can moderate these emotional responses. Methods: 617 individuals living in Tehran who regularly read the news about the COVID-19 from the early stages of spread completed an online survey. After excluding the participants with high scores from the Beck Depression Inventory (>18), data obtained from 443 participants were analyzed in terms of the experienced negative emotions and ER strategies. Results: Anxiety (55.8%) was the most common negative emotion reported by participants facing COVID-19-related news and problem-solving was the most frequent strategy used to control negative emotions. Both groups with high and low personal relevance indicated a similar pattern in experiencing high and low arousal emotions, as well as using ER strategies, and no significant differences were found (X2=0.006, p=0.51; X2=0.14, p=0.39, respectively). We also found that participants with high scores in the resilience scale used an integrative rather than a single approach of the ER strategies (rbp=0.15, p=0.01). Conclusion: We found that during the COVID-19 outbreak, news media may have important role in triggering anxiety in people who regularly read the relevant news, and problem-solving was the most frequent strategy among them. Being directly involved with COVID-19 in personal life did not make any differences in the way that individuals emotionally respond to the news. While using an integrative approach in regulating emotion was found in more resilient individuals. [ABSTRACT FROM AUTHOR]

Background: COVID-19 infection may present with atypical signs and symptoms and false negative polymerase chain reaction (PCR) tests predisposing healthy people and health care workers to infection. The aim of the current study is to evaluate the features of atypical presentations in COVID-19 infection in a referral center in Tehran, Iran.Methods: Hospital database of inpatients admitted to Loghman Hakim hospital between February 20th and May 11th, 2020 was reviewed and all patients with final diagnosis of COVID-19 infection were evaluated for their presenting symptoms. Patients with chief complaints of "fever", "dyspnea", and/or "cough" as typical presentations of COVID-19 were excluded and those with other clinical presentations were included.Results: Nineteen patients were included with a mean age of 51 ± 19 years, of whom, 17 were males (89%). Median [IQR] Glasgow coma scale (GCS) was 14 [13, 15]. Almost 10 had referred with chief complaint of methanol poisoning and overdose on substances of abuse. Only 8 cases (42%) had positive COVID-19 test. Nine (47%) needed invasive mechanical ventilation, of whom, two had positive COVID-19 test results (p = ns). Eight patients (42%) died with three of them having positive PCRs.Conclusions: In patients referring to emergency departments with chief complaint of poisoning (especially poisonings that can result in dyspnea including substances of abuse and toxic alcohols), gastrointestinal, and constitutional respiratory symptoms, attention should be given not to miss possible cases of COVID-19.
