Background: Estimating the net reproductive number of COVID-19 virus can reveal the rate and severity of the disease transmission in the Iranian society to health researchers and practitioners. Also, it signifies the importance of the disease to the community. Thus, the aim of this study was to determine the net reproductive number of COVID-19 in Iran and its different provinces. Methods: This study was conducted on the data of COVID-19 patients in Iran from February 21 to March 8, 2020. To determine the net reproductive number of COVID-19 in Iran, the serial interval and β value were first determined using linear regression analysis. Then, the net reproductive number values were calculated for Iran and its different provinces. Results: The results of this study showed that the net reproductive number of COVID-19 in Iran was 1.31. Using the available data up to March 15, 2020, the highest net reproductive number was in Mazandaran, Yazd, Isfahan, Qazvin, and Zanjan provinces, with values of 2.07, 1.86, 1.84, and 1.76, respectively. The net reproductive number also showed an increasing trend in Kohgiluyeh and BoyerAhmad province. Conclusion: It seems that although the net reproductive number of the virus had a decreasing trend in the provinces, it is still high. Therefore, sanitary measures in these provinces should be pursued more seriously. On the other hand, social distancing is a topic that should be taken into consideration, that is, social gatherings and contacts should be avoided as much as possible and strategies and facilities for this action should be developed by the government and health policymakers.
BACKGROUND: Given the wide range of depressive disorders, suicidal ideation and suicide attempts in various military studies around the world, determining the exact prevalence of these disorders in line with health planning as well as care and treatment service designing for military forces can be useful. The aim of the present meta-analysis was to determine the pooled prevalence of depressive disorders, suicide thoughts, and attempts in the military. METHODS: The present systematic review and meta-analysis study was performed based on PRISMA criteria in 5 steps of the search strategy, screening and selection of articles, data extraction, evaluation of article quality and meta-analysis. International databases (PubMed (Medline), Scopus, Web of science, Embase (Elsevier), PsycInfo (Ovid), Cochrane CENTRAL (Ovid)) were searched using related keywords extracted from Mesh and Emtree. After screening and final selection of articles, data were extracted and qualitative evaluation was performed using the NOS checklist. RESULTS: The results of meta-analysis showed that the prevalence of depression in active military forces and veterans was 23% ( CI: 20–26%) and 20% ( CI: 18–22%), respectively. In addition, the prevalence of suicidal ideation and attempts in the military was 11% ( CI: 10–13%) and 11% ( CI: 9–13%), respectively. The prevalence of suicide ideation and attempts in drug-using military was 18% ( CI: 7–33%) and 30% ( CI: 23–36%), respectively. The prevalence of suicidal ideation and attempts in military consuming alcohol were 9% ( CI: 4–13%) and 8% ( CI: 7–10%), respectively. In militaries with AIDS / HIV, the prevalence of suicide attempts was 5% ( CI: 4–8%). CONCLUSION: Therefore, it is necessary to develop and design training and intervention programs in order to increase the awareness of the military, especially veterans, to prevent the occurrence of suicide and depression.

Exposure to mercury is an important risk to dentists health. The aim of the present study was to assess the pooled mean mercury level (MML) in the urine, blood, nail, and hair of Iranian dentists (IDs) through the meta-analysis technique. Comprehensive and systematic searches were performed in main local databases including SID, Magiran, Iran medex, and ISC as well as internationally available databases including Embase, PubMed and Scopus for all the relevant studies up to 2018. In order to prevent bias in this study and identify eligible studies, various steps of the study was performed independently by two researchers. Out of 13 studies in the meta-analysis process which included 1499 IDs, the mean of the mercury level in the urine, nail, and blood was estimated to be 6.29 (95% CI: 2.61–9.97, I-square: 62.7%, P: 0.006), 3.54 (95% CI: 2.81–4.28, I-square: 0.0%, P: 0.968), 11.20 (95% CI: 2.28–20.13, I-square: 59.9%, P: 0.082), respectively. The mean mercury level (MML) in the biological samples of IDs was higher than the standard of World Health Organization (WHO). So, in accordance with Article 10 of the European Union Regulations (EUR), in the context of the Minamata Convention (MC) on Dental Amalgam (DA), in order to avoid the dangers of mercury exposure in dentists, it is necessary for Iran and other countries to approve laws and to implement a national plan to reduce mercury levels and replace the appropriate materials.

Background The rapid spread of COVID-19 renewed the focus on how health systems across the globe are financed, especially during public health emergencies. Development assistance is an important source of health financing in many low-income countries, yet little is known about how much of this funding was disbursed for COVID-19. We aimed to put development assistance for health for COVID-19 in the context of broader trends in global health financing, and to estimate total health spending from 1995 to 2050 and development assistance for COVID-19 in 2020.
