Background and Aim: By creating an international emergency, the COVID-19 pandemic may have led to compromised reproductive health care, including family planning services, and thus increased unintended pregnancies and unsafe abortions. This study was conducted to compare methods of contraception, abortion, and unintended pregnancies in those served by the health centers of Babol city in Iran, both before and during the COVID-19 pandemic., Methods: A cross-sectional study was conducted including 425 participants registered to the health centers of Babol city, Mazandaran province, Iran. Using a multi-stage method, 6 urban health centers and 10 rural centers were selected for inclusion. Proportional allocation method was used for sampling those who met the inclusion criteria. A questionnaire was used to collect data in relation to individual characteristics and reproductive behaviors via 6 questions focused upon methods and preparation of contraception, number and type of abortions, and number and causes of unintended pregnancy from July to November 2021. The data were analyzed using SPSS software version 26. Significance level was considered to be p < 0.05 in all tests., Results: Most participants aged between 20 and 29 years old had a diploma level of education, were housewives and lived in the city. Prior to the pandemic, 32.0% used modern contraceptive methods and 31.6% used these during the pandemic. No change in the combination of contraceptive methods used was observed between these two periods. Approximately two-thirds used the withdrawal method in both periods. The majority of participants in both periods purchased their contraceptives from a pharmacy. Unintended pregnancy increased from 20.4% prior to the pandemic to 25.4% during the pandemic. Abortions increased from 19.1% prior to the pandemic to 20.9% during the pandemic, although these findings were not found to be statistically significant. Contraceptive methods had a statistically significant relationship with age, education, spouse's education, spouse's occupation, and place of residence. The number of unintended pregnancies had a significant relationship with age, the educational level of both participants and their spouses and socio-economic status, and the number of abortions had a statistically significant relationship with the age and education level of the spouse (p > 0.05)., Conclusion: Despite there being no change in contraceptive methods compared to the pre-pandemic period, an increase in the number of unintended pregnancies, abortions and illegal abortions was observed. This may be indicative of an unmet need for family planning services during the COVID-19 pandemic., (© 2023. The Author(s).)

Background and Aim: Reproductive behaviors and intentions are affected by several factors, including the COVID-19 pandemic crisis. This study was conducted with the aim of comparing the intention to reproduce and its causes in Iran during the period prior to and during the COVID-19 pandemic., Methods: This descriptive-comparative study included 425 cisgender women from 6 urban health centers and 10 rural centers in Babol city, Mazandaran province, Iran. Urban and rural health centers were selected using a multi-stage approach with proportional allocation. A questionnaire was used to collect data in relation to individual characteristics and reproductive intentions., Results: Most participants aged between 20 and 29 years had a diploma level of education, were housewives and lived in the city. The intention to reproduce decreased from 11.4% before the pandemic to 5.4% during the pandemic (p = 0.006). The most common reason for wanting to have children prior to the pandemic was not having children (54.2%). During the pandemic, a desire to reach the ideal number of children was the most common reason to want to have children (59.1%), though no statistically significant difference was observed between the two periods (p = 0.303). The most common reason for not wanting to have children in both periods was having enough children already (45.2% before and 40.9% during the pandemic). The reasons for not wanting to have children had a statistically significant difference between the two periods (p < 0.001). Reproductive intentions had a statistically significant relationship with the variables of age (p < 0.001), the education level of both participants (p < 0.001) and spouses (p = 0.006), occupation (p = 0.004), and socio-economic status (p < 0.001)., Conclusion: Despite restrictions and lockdowns, the COVID-19 pandemic had a negative impact on people's desire to reproduce in this context. Economic problems caused by the sanctions which increased during the COVID-19 crisis may be one of the reasons for a reduction in people's intentions to become parents. Future research could usefully investigate whether this decrease in the desire to reproduce will lead to significant changes in population level and future birth rates., (© 2023. The Author(s).)

Background: Given that COVID-19 continues to spread worldwide, attempts to restrain the virus and to prevent the effects that critically ill patients with COVID-19 have on healthcare systems, has become a public health priority. This ecological study aimed to investigate the correlation between the Human Development Index (HDI) and the epidemiological indicators of COVID-19, including the cumulative incidence rate of cases, the cumulative incidence rate of death, performed COVID-19 tests per million, recovery rate, and case fatality rate., Methods: In this ecological study, a data set was provided, which included the epidemiologic indices of COVID-19, HDI, and its components for each country. Correlation coefficients were used to determine linear correlation. Also, the scatter plots of the HDI for the studied countries based on the epidemiologic indices of COVID-19 were drawn., Results: This study showed that HDI and its components had positive correlation with a cumulative incidence rate of cases, the cumulative incidence rate of death, and performed COVID-19 tests (p < 0.001). HDI and two of its components, including literacy and Gross National Income (GNI) components had negative correlation with case fatality rate (CFR). Also, HDI and two of its components, including literacy and life expectancy components had negative correlation with recovery rate., Conclusion: Our study showed that the HDI and its components can affect the epidemiological status of COVID-19. As HDI increased, the cumulative incidence rate of cases, cumulative incidence rate of death, and COVID-19 tests increased as well. As HDI increased, CFR and recovery rate decreased as well. Although the HDI is higher in high-income countries, these countries may have also better reporting and surveillance systems., (© 2022. The Author(s).)

Background: Effective measures to control COVID-19 should be based on an understanding of its epidemiological pattern and the evaluation of its prevalence in the community. This study aimed to examine the reproductive number (R) of COVID-19 and its trend in Fars Province in southern Iran., Methods: In this ecological study, the R trend was examined from July to November 2020. Data were collected from the daily reports of Shiraz University of Medical Sciences. R is the product of three components, namely the number of infection-producing contacts per unit time, the probability of transmission per contact, and the contagiousness period. Incidence and prevalence rates were used to calculate R. The R value was calculated in Microsoft Excel 2016., Results: The first and second peaks of COVID-19 were observed on July 6 th and November 22 nd , respectively. The median and mean of R were 1.42 and 1.41, respectively. The highest and lowest values of R were observed on October 20 th (2.60) and September 1 st (0.46), respectively. The values of R had a slightly decreasing trend in the second half of July and November than the first half. In the second half of August and September, an increasing trend was observed than the first half. There was not much change in the second half of October., Conclusion: The highest value of R was related to the dates when there was a higher probability of exposure to the virus, including public holidays and different occasions on which the probability of people's participation in ceremonies, communities, and gatherings was higher., (Copyright: © Iranian Journal of Medical Sciences.)

This global level ecological study aimed to investigate the correlation between environmental factors and the COVID-19 indices. This survey is an ecological study, so all studied variables are aggregate variables. To collect the variables in the study, a data set was provided, which includes the information of each country based on the cumulative deaths, case fatality rate, recovery rate, and the number of performed COVID-19 tests. Scatter plots of environmental factors for the studied countries were drawn based on cumulative incidence rate of cases, cumulative incidence rate of death, tests, recovery rate, and case fatality rate of COVID-19. Furthermore, Spearman correlation coefficient was also used to verify the correlation between environmental factors and indicators related to COVID-19. The results of this ecological study showed that among all countries surveyed, Montenegro (60,310.56 per million) and Luxembourg (54,807.89 per million) had the highest cumulative incidence rates of COVID-19 cases, when Tanzania (8.42 per million) and Vietnam (13.78 per million) had the lowest cumulative incidence rates of COVID-19. In addition, in this study, it was shown that the cumulative incidence rate of cases, the cumulative incidence rate of deaths, and performed COVID-19 tests had significant direct correlations with the access to drinking water and the access to sanitation services (p < 0.001). The findings of the present study showed an inverse correlation between the mortality rate due to unhealthy water consumption, poor health status, and a positive correlation between access to drinking water and health services with the cumulative incidence and mortality rates of COVID-19. The differences between our findings and many other studies could be due to the ecological nature of the study. Nevertheless, our findings will help health policymakers to develop timely strategies to reduce the mortality and incidence rate of COVID-19., (© 2021.

Introduction: COVID-19 is a highly contagious respiratory disease and many factors can affect its severity and mortality. This study aimed to investigate the risk factors associated with the severity and mortality of COVID-19., Methods: In this cross-sectional study, 311 cases with COVID-19 approved by the CORONALAB database in the Center for Disease Control and Prevention (CDC) in southern Iran were selected using systematic random sampling from 15 May to 13 June 2020. The data were collected through interviews and phone calls using a researcher-made questionnaire., Results: The mean age of the participants was 45.82 ± 17.92 years, and the male to female ratio was 1.57:1. In addition, the Case Fatality Rate (CFR) was 4.50%, and the disease was severe in 47.5% of the cases. The most common clinical symptoms were cough (39.22%), fever (31.83%), and dyspnea (24.76%). The severity of COVID-19 was significantly associated with age and history of Cardiovascular Disease (CVD). Besides, the mortality of COVID-19 was significantly related to age, gender, hypertension, CVD, and Chronic Kidney Disease (CKD). The mean interval between the onset of the first symptom and referral to a health center was 3.02 ± 2.82 days. Additionally, the mean interval between the referral to health centers and testing was 0.88 ± 2.20 days., Conclusion: Older patients, males, and those who had CVD, CKD, and hypertension required accurate healthcare and early intervention to prevent the exacerbation of COVID-19. Furthermore, the interval between the onset of the first symptom and testing was relatively long. Overall, early diagnosis, isolation, and treatment of patients were found to be essential to control COVID-19., Competing Interests: Conflict of interest statement The authors declare no conflict of interest., (©2021 Pacini Editore SRL, Pisa, Italy.)

Introduction: Coronavirus is threatening the global public health as a new and widespread crisis. The researchers must keep in mind that one of the most vulnerable groups to COVID-19 are the people with underlying diseases, especially diabetes. Objective: This ecological study aimed to investigate the correlation between diabetes and the epidemiological indices of COVID-19. Methods: This ecological study included 144 countries. Their available data consists of the cumulative incidence rate of cases, cumulative incidence rate of death, recovery rate, case fatality rate, and performed tests of COVID-19, and diabetes. To collect the variables, a data set was provided which included the information of 144 countries based on diabetes and COVID-19 indices. Spearman coefficients were used for assess correlation between diabetes and COVID-19 indices. Also, Scatter plots of diabetes for the studied countries were drawn based on cumulative incidence rate of cases, cumulative incidence rate of death, tests, recovery rate, and case fatality rate of COVID-19. Results: The results of this ecological study showed in total countries, there was a weak positive correlation between diabetes and cumulative incidence rate of cases and also cumulative incidence rate of death. Correlation between diabetes with test of COVID-19 was very weak. Scatter plots showed a weak liner correlation between diabetes and cumulative incidence rate of cases, cumulative incidence rate of death and test of COVID-19. Conclusions: In this study, there was a weak positive correlation between diabetes and cumulative incidence rate of cases, cumulative incidence rate of death, and performed test of COVID-19. This disease is an enormous challenge for health policymakers; therefore, it is necessary to develop strategies and practical guidelines specific to each region to take the necessary care, especially for diabetic patients.

Managing the disastrous consequences of pandemics depends on the capacity of the governments to mitigate them. As the health system in Iran was undertaking economic issues because of sanctions, the government has been forced to make major and urgent decisions while anticipating the economic, social, and political effects of the COVID-19 pandemic. Therefore, Iran has integrated all critical sections of the community to provide a unified command structure to involve all stakeholders. In this regard, we present a disaster management structure in response to the COVID-19 pandemic in Iran. We hope to provide information on the advantages that might change disaster management structure in pandemics. [ABSTRACT FROM AUTHOR]

Companies recently have increased the focus on performing social responsibilities. Charitable aids are one dimension of corporate social responsibility. In this regard, following the COVID-19 epidemic in Iran, private sectors (PSs) offer some assistance in wider and coherent cooperation. Therefore, PSs' association created a campaign, where donations were allocated based on the need priorities. The campaign revived the missing link between the public and the private sectors and the NGOs (non-Governmental Organisations), and forward to achieving the goals of sustainable development.

Identifying signaling pathways and molecules involved in SARS-CoV-2 pathogenesis is pivotal for developing new effective therapeutic or preventive strategies for COVID-19. Pannexins (PANX) are ATP-release channels in the plasma membrane essential in many physiological and immune responses. Activation of pannexin channels and downstream purinergic receptors play dual roles in viral infection, either by facilitating viral replication and infection or inducing host antiviral defense. The current review provides a hypothesis demonstrating the possible contribution of the PANX1 channel and purinergic receptors in SARS-CoV-2 pathogenesis and mechanism of action. Moreover, we discuss whether targeting these signaling pathways may provide promising preventative therapies and treatments for patients with progressive COVID-19 resulting from excessive pro-inflammatory cytokines and chemokines production. Several inhibitors of this pathway have been developed for the treatment of other viral infections and pathological consequences. Specific PANX1 inhibitors could be potentially included as part of the COVID-19 treatment regimen if, in future, studies demonstrate the role of PANX1 in COVID-19 pathogenesis. Of note, any ATP therapeutic modulation for COVID-19 should be carefully designed and monitored because of the complex role of extracellular ATP in cellular physiology.

In order to accurately interpret the immune response to COVID-19, it is critical to know how long serum antibodies to COVID-2 persist. This study aimed to describe the serum IgG responses to SARS-CoV-2 in patients with mild, moderate, and severe COVID-19 infection in Birjand, South Khorasan province, Iran. The study was performed on individuals whose COVID-19 disease was confirmed by RT-PCR and recovered from the disease. After completing the questionnaire, blood samples were collected from 4 different groups based on the time of the test at two, four, six, and eight months' post-recovery. Then, SARS-COV-2 virus-specific IgG nucleocapsid antibody level in patients was measured using the enzyme-linked immunosorbent assay (ELISA). In total, 206 patients (mean age 44.19 ​± ​14.9, 51% man) were included in the survey. Serum prevalence of specific IgG antibodies in patients with mild, moderate, and severe COVID-19 disease was 51.5%, 64% and 78.9%, respectively. Furthermore, serum prevalence of COVID-19 specific IgG antibody level in two, four, six, and eight months after recovery were 80.8, 69.1, 43.2 and 41.8%, respectivel y (p ​< ​0.05). The multiple logistic regression model showed that the variables of age and the time elapsed after recovery had a significant relationship with the positive antibody test of recovered COVID-19 patients (P ​< ​0.05). But other variables had no significant relationship with the result of antibody test (P ​> ​0.05). In the present report, we attempted to characterize the antibody response against SARS-CoV-2 in patients with mild, moderate, and severe COVID-19, with the aim of better elucidating the humoral immune response after recovery from SARS-CoV-2 infection.
