Climate change and health: The case of mapping droughts and migration pattern in Iran (2011-2016).

INTRODUCTION: Migration and mobility of population have been reported as a common reaction to drought. There is historical evidence to suggest the health effects of droughts and human migration linkage in Iran. This study aimed to map the drought and migration patterns in Iran in 2011 and 2016 and explore their possible health impacts. METHODS: This sequential explanatory mixed-method study was done in two stages of spatial analysis and qualitative study. Data mapping was conducted through the equal interval classification and using drought, migration, and agriculture occupation data based on provincial divisions in Iran in 2011 and 2016. This qualitative study was conducted using the content analysis approach. RESULTS: The in-migration rate was higher in 2011 rather than 2016. Migration to cities was much higher than migration to villages in both years. The frequency of male migrants was higher than females in all provinces in 2011 and 2016. Physical and mental diseases as well as economic, sociocultural, education, and environment effects on health were extracted from the qualitative data. CONCLUSION: A holistic picture of droughts and migration issues in Iran and their health consequences were achieved by the present research. Further research is needed to explore the determinants of health impacts of climate change in vulnerable groups. Public health problems can be prevented by adaptive and preventive policy-making and planning. This can improve the coping capacity of the population facing droughts and enforced migration.

A systematic review and meta-analysis of musculoskeletal disorders among firefighters.

INTRODUCTION: Due to the nature of their job, firefighters face many ergonomic risk factors and are exposed to several musculoskeletal disorders (MSDs). The aim of this systematic review and meta-analysis was to investigate the prevalence of MSDs among firefighters. MATERIALS AND METHODS: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The literature search was conducted in the databases of PubMed, Scopus, Web of Science, Science Direct, SID, ISC and Google Scholar without applying a time limitation until the end of July 2022. The random effects model was used for meta-analysis, and the I2 index was used to check heterogeneity among studies. The data were analyzed using STATA version 14 software. RESULTS: The primary literature searches in the databases identified 1,291 articles, 26 of which were entered the meta-analysis stage after screening, study selection, and quality assessment, including 36,342 firefighters. Based on the results of a meta-analysis, the overall prevalence of MSDs among firefighters was 46.39% (95% CI: 32.45-60.32, I2 = 99.7%, P < 0.001). The prevalence of MSDs was also investigated at neck (18.36%), low back (34.32%), shoulder (18.68%), hands (7.43%), upper back (10.15%), knee (19.97%) and foot (6.66%). CONCLUSION: Considering the relatively high prevalence of MSDs among firefighters and their higher exposition to specific job-related risk factors of MSDs compared to other professions, it is suggested to provide firefighters with appropriate training, implement ergonomic interventions, and regularly screen them to reduce MSDs.

Explaining of the experts' points of view about the types and importance of man-made hazards in Iran's process industries: A qualitative study.

Introduction: Process industries may have different hazards that can cause serious injury to humans, the environment, and the economy. Considering the importance of man-made risks in process industries, Experts' Points of View should be considered to apply risk reduction strategies Hence, the present study was performed to explain the views of experts regarding the types and importance of man-made hazards in process industries. Materials and methods: This study was conducted using a qualitative method of directed content analysis with a deductive approach. The participants included 22 experts in the field of process industries. The selection of samples started purposeful and continued until data saturation. Data collection was done through semi-structured interviews. Results: Based on experts' points of view, 5 man-made hazards in process industries were classified into 14 subcategories. The man category was divided into three subcategories: human error, technical knowledge error, and management error, the Material category was divided into 3 sub-categories of leakage and rupture, chemical properties, physical properties, Medium category was divided into two sub-categories of incorrect location selection and placement and harmful environmental factors, Machines category was divided into three sub-categories of failure in design, failure in Preventive Maintenance (PM), failure in Safety Instrumented System (SIS), and the Methods category was classified into three sub-categories: defects in inspection, defects in information, defects in executive instructions. Conclusion: Technical training to reduce personnel errors, conducting risk-based inspections to control leaks and possible ruptures, careful design and site selection in the initial phase of the project, is recommended. The use of engineering methods and artificial intelligence to obtain the risk number and control methods to reduce the harmful effects of risks can be helpful.

The challenges of health volunteers management in COVID19 pandemic in Iran.

PURPOSE: The use of volunteers is one of the approaches to capacity building, preparedness and the response of the health system in disasters. Appropriate management of volunteers during disasters and emergencies is essential. This study aimed to explain the challenges of volunteer management in the Pandemic COVID-19 in Iran. DESIGN/METHODOLOGY/APPROACH: Qualitative research was conducted using the content analysis based on the Graneheim method. The participants' selection was done based on purposeful sampling and theoretical sampling until data saturation. Direct field observation and 26 interviews were applied to collect data. FINDINGS: Four categories and 15 sub-categories emerged to describe the challenges of volunteer management during the COVID-19 crisis including policymaking barriers (including legal barriers, insurance and support coverage and risk governance), managerial barriers (including planning, coordinating and organizing, training and awareness, command and leadership and information management and documentation), socio-cultural barriers (personal safety attitude and culture, attitudes and expectations of the community and perspectives on volunteers) and executive-operational barriers (monitoring and evaluation, cost and needs assessment). ORIGINALITY/VALUE: It is essential to increase managers', officials' and volunteers' perceptions of COVID19 risk through education and information. Preparing a database for volunteers' information, including non-governmental organization and governmental organization volunteers, planning for needs assessment, establishing a mechanism for recruiting volunteers and using their capacities and appropriate organizing, tracking and monitoring of volunteers can be among effective strategies.

Prevalence of Influenza Among Hajj Pilgrims: A Systematic Review and Meta-Analysis.

OBJECTIVES: Respiratory transmission, especially in mass gatherings, is considered one of the main ways of influenza transmission. The Hajj ceremony, as one of the largest gatherings worldwide, can increase the distribution of influenza infection. Thus, the present study aimed to evaluate the incidence of influenza among Hajj pilgrims. METHODS: In this present systematic review and meta-analysis, all English studies published by 2019 were extracted from several databases such as the Web of Science, PubMed, Scopus, Cochrane Library, Science Direct, and Google Scholar. Finally, the data were extracted using a pre-prepared checklist and then analyzed by fixed and random effects model tests in the meta-analysis, Cochran, meta-regression, and Begg's test. RESULTS: Eighteen studies with a sample size of 62 431 were entered into the meta-analysis process. The overall prevalence of influenza, in addition to the prevalence of types A, B, and C influenza, was estimated at 5.9 (95% CI: 4.3-8.0), 3.6 (95% CI: 2.6-4.9), 2.9 (95% CI: 2.8-3.1), and 0.9% (95% CI: 0.5-1.5), respectively. CONCLUSIONS: In general, influenza remains widespread regardless of vaccinating pilgrims and following health protocols. Therefore, it is recommended that comprehensive management and educational approaches be used to reduce the prevalence of influenza and its adverse consequences among the pilgrims.
