Disasters and emergencies have been increasing all over the world. Todays, with technological advancement, acquiring knowledge and its application in the realm of action is regarded as the only effective way for prevent disasters or reducing its effects. The present study aimed to review the importance of education and the effect of different methods of education on disaster risk reduction and preparedness in vulnerable people. To this aim, some articles indexed in Database of PubMed, Web of Science, Google Scholar, Scopus, Science Direct, and ProQuest were searched. The search was limited to reviewed articles in English published between 1990 and 2017. In addition, the selected articles were reviewed for relevant citations. The conducted studies were reviewed by two researchers independently. The primary search generated 128 relevant references. After eliminating the duplicates and articles which were not related to the review of the abstract, 41 references were identified for inclusion. After reviewing more, 31 references, which failed to meet inclusion index, were excluded from the study. Disaster education aims to provide knowledge among individuals and groups to take actions to reduce their vulnerability to disasters. During the last decades, the issue that trained people can be prepared for disasters and responding well has been extensively investigated. Based on the results, disaster education is a functional, operational, and cost-effective tool for risk management. Based on some evidence, it is important for vulnerable people to learn about disasters. There are different methods to educate vulnerable people, but no method is better than others. Trained people can better protect themselves and others. In this regard, planning and designing comprehensive educational programs are necessary for people to face disasters.

Background: It is generally assumed that there have been mixed results in the literature regarding the association between ambient particulate matter (PM) and myocardial infarction (MI). The aim of this meta-analysis was to explore the rate of short-term exposure PM with aerodynamic diameters ≤2.5 μm (PM 2.5) and examine its potential effect(s) on the risk of MI. Methods: A systematic search was conducted on databases like PubMed, Scopus, Web of Science, and Embase with components: "air pollution" and "myocardial infarction". The summary relative risk (RR) and 95% confidence intervals (95%CI) were also calculated to assess the association between the PM 2.5 and MI. Results: Twenty-six published studies were ultimately identified as eligible candidates for the meta-analysis of MI until Jun 1, 2018. The results illustrated that a 10-μg/m 3 increase in PM 2.5 was associated with the risk of MI (RR = 1.02; 95% CI 1.01-1.03; P ≤ 0.0001). The heterogeneity of the studies was assessed through a random-effects model with p < 0.0001 and the I 2 was 69.52%, indicating a moderate degree of heterogeneity. We also conducted subgroup analyses including study quality, study design, and study period. Accordingly, it was found that subgroups time series study design and high study period could substantially decrease heterogeneity (I 2 = 41.61, 41.78). Conclusions: This meta-analysis indicated that exposureresponse between PM 2.5 and MI. It is vital decision makers implement effective strategies to help improve air pollution, especially in developing countries or prevent exposure to PM 2.5 to protect human health.

Background:One of the main factors relating to quality of hospitals is effective discharge planning. Discharge planning promotes the quality of inpatient care and reduces unplanned hospital readmission. The current study investigated the challenges of discharge planning observed in the health system of Iran.Methods:This qualitative research was conducted using a thematic and framework analyses to identify the challenges under each themes defined by the World Health Organization (WHO), to understand barriers in developing an effective discharge planning system in Iran health system. The data was collected from detailed semi-structured interviews and sessions of focus group discussions. This study involved 51 participants including health policy makers, hospital and health managers, faculty members, nurses, practitioners, community medicine specialists and other professionals of the Ministry of Health and Medical Education (MOHME). To reduce the bias and to increase the credibility of the study, evaluation criteria from Lincoln and Guba were used. All interviews and FGDs were recorded and transcribed, then analyzed by the software MAXQDA-11 and also manually.Results:According to the WHO health systems framework, challenges of effective hospital discharge planning were divided into six areas, leadership/governance, service delivery, information, financing, health workforce, and medical production(themes), in which there were 5,3,2,2,3,1 subthemes respectively.Conclusion:It is evident from the findings of this study that changes in the perspective of policy makers, health staff and managers, strengthening of systematic approach, and establishment of required infrastructures are essential for successful implementation of effective discharge planning in health systems in Iran.

Introduction: Senior citizens or the elderly people are a group of people in the society considered as a growing population with special needs in the developed contemporary world. Since they have special needs, it is essential to care about the quality of their life because of the dangers which threaten them. Since the social health of the retirees is decreased as a result of exiting from the workplace and directly affecting their life quality, the researcher has done the present study.Methodology: This paper which is a descriptive-analytic study has been periodically done in the second half of 2013. The participants were 227 senior retirees of Tehran University of Medical Sciences. The data have been collected through a reliable and valid questionnaire of life quality related to health (sf-36) and social well-being of KEYES. The data then were analyzed using SPSS.19 and descriptive statistics and paired t-test, one way ANOVA test and Pearson correlation were use as well. Findings:There is a significant linear relation between life quality variable related to the health and social well-being components (P<0.05). There is also a significant correlation between the variables like age, sex, marital status, duration of employment and life quality. Results:Regarding the findings of the study, it seems that the policy makers and planners need to create a kind of active integration and balance in society according to the available devices and facilities, and try to apply a proper information system to eliminate the cultural problems, reinforce the social relations and coherences in order to increase the life quality of senior retires.
