Background: Acute submassive a massive pulmonary embolism are known as leading causes of cardiovascular morbidity and mortality in emergency departments. Choosing the optimal type of catheter directed thrombolysis (CDT) for treatment of pulmonary embolism presents a quandary to the practitioners. To the best of our knowledge, there is no meta-analysis comparing superiority of conventional CDT and ultrasound-accelerated catheter directed thrombolysis (USACDT). Therefore, in this meta-analysis, we aimed to compare conventional CDT with USACDT regarding clinical outcomes and safety profile.

Methods: A systematic literature search of previous published studies comparing conventional CDT with USACDT regarding clinical outcomes and safety profile was carried out in the electronic databases including MEDLINE, Scopus, EBSCO, Google Scholar, Web of Science, and Cochrane from inception to December 2021. Data were analyzed by comprehensive meta-analysis software (CMA, version 3).

Results: The meta-analysis included nine studies with a total of 705 patients. Our meta-analysis showed that there is no significant difference between two groups with respect to pulmonary arterial systolic pressure (SMD: -0.084; 95% CI: -0.287 to 0.12; : 0.41), RV/LV (SMD: -0.003; 95% CI: -0.277 to 0.270; : 0.98), and Miller score (SMD: -0.345; 95% CI: -1.376 to 0.686; : 0.51). Similarly, we found no statistically significant differences between two groups regarding major and minor bleeding ( > .05).

Conclusion: Our meta-analysis showed that when compared with USACDT, conventional CDT provides similar clinical and hemodynamic outcomes or safety for treatment of pulmonary embolism without the need for very expensive technologies. However, randomized clinical trials are required to further investigate cost-effectiveness of USACDT in comparison with conventional CDT.

Accuracy of Triage Systems in Disasters and Mass Casualty Incidents; a Systematic Review.

Arch Acad Emerg Med 2022 30;10(1):e32. Epub 2022 Apr 30.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Introduction: To prioritize patients to provide them with proper services and also manage the scarce resources in emergencies, the use of triage systems seems to be essential. The aim of this study was to evaluate the accuracy of the existing triage systems in disasters and mass casualty incidents.

Methods: The present study is a systematic review of the accuracy of all triage systems worldwide. The results of this study were based on the articles published in English language journals. In this research, all papers published from the beginning of 2000 to the end of 2021 were sought through different databases. Finally, a total of 13 articles was ultimately selected from 89 articles.

Results: 13 studies on the accuracy of triage systems were reviewed. The START, mSTART, SALT, Smart, Care Flight, ASAV, MPTT, Sieve and ESI triage systems, had an accuracy, sensitivity, and specificity of less than 90%. Only the Smart triage system had an overall accuracy of more than 90%.

Conclusion: According to the findings of the current systematic review, the performance of the existing triage systems in terms of accuracy of prioritizing the injured people and other performance indexes is not desirable. Therefore, to improve the performance and increase the precision of triage systems, the world nations are recommended to change or revise the indexes used in triage models and also identify other influential factors affecting the accuracy of triage systems.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Background: Nowadays, emergencies and disasters are considered one of the biggest problems in human life. To reduce the risk of emergencies and disasters, governments must develop strategies and policies using evidence-based methods. Disaster databases are the main source and tool for storing and managing a wide range of data in this field. This study was conducted with the aim of exploring the necessary criteria and components of the emergency and disasters database in Iran.

Martials And Methods: This qualitative study was performed using content analysis in which 18 managers and experts with experience in registering, documenting, or responding to emergencies and disasters were selected through purposive sampling. Data collection was done using semi-structured interviews that continued until saturation. Data were analyzed by means of qualitative content analysis recommended by Landman and Graneheim.

Results: In total, three main concepts concerning the necessary criteria and components of the database of natural and artificial emergencies and disasters in Iran were explored. The main concepts include information resources, information evaluation, and information management. Subconcepts include data collection, information transfer, access to information, information validation, disaster leveling, information registering, information storage and retrieval, information analysis, and information dissemination.

Conclusion: The experience of the participants showed that there are many challenges in the field of monitoring and gathering information about injuries and damages caused by emergencies and disasters in the country. The knowledge obtained from this study can be used to create and develop a database of emergencies and disasters in Iran. It will also provide insights for healthcare policymakers and managers in future planning areas to more effectively address identified challenges in preventing and responding to disasters at both regional and national levels.

Effects of dust events and meteorological elements on stroke morbidity in northern Khuzestan, Iran.

J Educ Health Promot 2021 30;10:406. Epub 2021 Nov 30.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Background: In recent years, the prevalence of dust events has increased in the region and the world. According to the Meteorological Organization, the most frequent days with dust events are on stations located in Khuzestan province. Objective: Assessment of the effects of dust events and meteorological elements on stroke morbidity in health in Iran: a health promotion approach.

Materials And Methods: The present study was a retrospective cohort study 2020 and 2013 provided between based on ecological data-based on population. Information about patients with stroke was obtained from the hospital. Information on the dust events and meteorological elements was also from the data center of the Meteorological Organization of Iran. Using STATA the correlation between the diseases and the, 14 statistical software version occurrence of dust events and changes in meteorological elements was obtained and the statistical model (Spearman correlation coefficient) individually estigate the equation was used inv modified by Poisson regression simultaneous effect of variables.

Results: the results of adjusted statistical models show that increasing the severity of dust event increases the risk of stroke in males (lag 0-21 confidence interval [CI] 95% = 1.496-1.0067 relative risk [RR] = 1.03 = 0.01). Increasing the average wind speed also increases the risk of stroke in males (lag 0-3 CI 95% = 1.0491-0.9996 RR = 1.02 = 0.05). Increased rainfall and average relative humidity increase the risk of stroke in people under 60 years (lag 0-7 CI 95% = 1.0012-0.9058 RR = 1.95 = 0.05). Increasing the average daily temperature reduces the risk of stroke in males (lag 0-3 CI 95% = 0.9874-0.9254 RR = 0.51 < 0.001).

Conclusion: Increasing the intensity of dust storms along with meteorological elements has increased the risk of stroke. However, increasing the average temperature has had a protective effect on the risk of stroke.

Screening Performance Characteristics of Ultrasonography in Confirmation of Endotracheal Intubation; a Systematic Review and Meta-analysis.

Arch Acad Emerg Med 2021 26;9(1):e68. Epub 2021 Oct 26.

School of Medicine, Jahrom University of Medical Sciences, Jahrom, Iran.

Introduction: Recent studies have suggested that point-of-care ultrasonography can be used for confirming the placement of endotracheal tube. This systematic review and meta-analysis aimed to investigate the sensitivity and specificity of ultrasonography for confirming endotracheal tube placement.

Methods: In this meta-analysis, systematic search of the previous published papers investigating the diagnostic accuracy of ultrasonography for confirmation of endotracheal tube placement was performed. Seven electronic databases, including PubMed, Scopus, Google Scholar, EBSCO, EMBASE, Web of Science, and Cochrane Database were searched up to July 2021, for all relevant articles published in English on this topic. Meta-DiSc version 1.4 software was used for statistical analysis.

Results: The estimated pooled sensitivity and specificity of ultrasonography for confirmation of endotracheal tube location were 0.98 (95% CI: 0.98-0.99) and 0.94 (95% CI 0.91-0.96), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 5.94 (95% CI 4.41-7.98) and 0.03 (95% CI: 0.02-0.04), respectively. The diagnostic odds ratio of ultrasonography was 281.47 and the area under hierarchical summary receiver operating characteristic (HSROC) revealed an appropriate accuracy of 0.98.

Conclusion: Ultrasonography has high diagnostic accuracy and can be used as a promising tool for confirmation of endotracheal tube placement, especially in critically ill patients or when capnography is not available, or its result is equivocal.

The Barriers, Challenges, and Strategies of COVID-19 (SARS-CoV-2) Vaccine Acceptance: A Concurrent Mixed-Method Study in Tehran City, Iran.

Vaccines (Basel) 2021 Oct 28;9(11). Epub 2021 Oct 28.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran 1985713871, Iran.

Acceptance and willingness to receive the vaccine are among the main factors in the success or failure of a health system in implementing the vaccination program. The present study was conducted in Tehran, the political and economic capital of Iran, to determine the acceptance of the COVID-19 vaccine and identify its associated factors, and explain the most important barriers and acceptance strategies for vaccination. This research was a concurrent quantitative and qualitative mixed-method study. In the quantitative part, 1200 individuals aged more than 18 years were selected from the households in 22 districts of Tehran City, with a multistage stratified cluster sampling method. Two questionnaires were used to evaluate the acceptance of the COVID-19 vaccine and vaccine acceptance determinants. The qualitative content analysis method addressed the influencing factors, as well as challenges and strategies related to the acceptance of the COVID-19 vaccine in four groups of Tehran inhabitants: the elderly, people with underlying diseases, healthcare workers, and the general population. The related data were simultaneously collected by applying in-depth semi-structural interviews and a data analysis process. Furthermore, we used the Graneheim and Lundman method for data analysis. We analyzed the data of 1200 people with a mean (SD) age of 46.4 (11.1) years, and approximately 58% of them were men. The vaccine acceptance was 83.6% (95% CI: 81.3-85.9). Among those who welcomed vaccination, 58% preferred the imported vaccines, 25% the Iranian ones, and 17% both. There was a significant association between the variables of age (adjusted odds ratio [AOR] = 1.72, 95% CI: 1.01-2.93), being single (AOR = 0.54, 95% CI: 0.41-0.91), moderate pharmacotherapy adherence (AOR = 0.58, 95% CI: 0.4-0.85), and the willingness to receive COVID-19 vaccine. Qualitative study after interviewing 45 people from four study groups showed an insufficient social trust in healthcare system officials, pharmaceutical and vaccine production companies; distrust in the effectiveness of the vaccines, concerns about the vaccine adverse effects, being tracked by microchips after vaccination, traditional anti-vaccination movements, the feeling the inessentiality of vaccination, and uncertainty about the fair distribution of the vaccine. These concerns were the main challenges addressed by the study groups. A good proportion of Tehran residents reported their willingness to receive the COVID-19 vaccine. Additionally, they expressed their critical concerns, such as insufficient trust in the healthcare system, vaccine safeties, and adverse effects that were the significant barriers to vaccine acceptance. It seems that conflicts raised by the shortage of vaccines and their import due to the sanctions have led to intense desire and demand in the general population, and especially the elderly, for vaccination. Besides, vaccination phobia in some individuals requires further investigations.

Worldwide disaster loss and damage databases: A systematic review.

J Educ Health Promot 2021 30;10:329. Epub 2021 Sep 30.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Nowadays, disaster databases have become a valuable tool for disaster risk management and health promotion and serve various purposes. The purpose of this study is to provide a systematic review of disaster databases in the world and to identify the objectives, information sources, criteria, and variables of disaster data registration in the world's reputable databases. To conduct review, all English-language articles published without a time limit until the end of September 2020 were extracted from the databases of Web of Science, PubMed, Scopus, Cochrane Library, Science Direct, Google Scholar, and Embase. Necessary information in the papers including study time, type of disasters, related databases, dimensions and indicators of global and regional databases were extracted by using a researcher-made questionnaire. A total of 22 studies have been reviewed to identify the dimensions and indicators of disaster databases worldwide. The main focus was on global and regional databases, mostly used at the level of scientific societies and disaster experts. After explanation, researchers highlighted each of the disaster databases, along with the main differences available among the existing databases. Some databases have well-defined data collection methods. Their knowledge is high quality and they can be used to create and improve a disaster database at other levels. Disaster database limitations include risk bias, time bias, accounting bias, threshold bias, and geographical bias. To support the right decisions to reduce disaster risk, it is necessary to complement existing global, regional, and national databases. Countries need to take action to set up national databases.

Challenges to manage pandemic of coronavirus disease (COVID-19) in Iran with a special situation: a qualitative multi-method study.

BMC Public Health 2021 10 22;21(1):1919. Epub 2021 Oct 22.

Surgery Department, University of Tubingen, Tübingen, Germany.

Background: With the unprecedented expansion of COVID-19 in the world since December 2019, Iran's health system, like other countries, faced various challenges in managing the disease, which led to numerous experiences and lessons learned. This study was conducted to identify these challenges regarding unique political, economic, and cultural issues, which could help other countries with similar situations.

Methods: The present study was performed using a qualitative multi-method approach with a content analysis method. The data were collected through in-depth and semi-structured interviews and focused group discussions with 60 key persons who were selected purposefully, including policymakers, health care workers, and affected people by the disease, and the review of all available national reports between February 21, 2020, and March 22, 2021. The data collection and analysis were done simultaneously.

Results: Identified critical challenges for the management of COVID-19 in the health system were limited evidence and scientific controversies, poor social prevention and social inequalities, burnout and sustained workload among healthcare workers, improper management of resources and equipment, the lack of a guideline for contact tracing, and patient flow management, and mental health problems in the community.

Conclusions: According to our results, measures should be taken to conduct a continuous comprehensive risk assessment and develop a national response plan with an emphasis on precise contact tracing, active screening, patient flow, paying attention to the psychological and social dimensions of the disease, and also transparency of social inequalities in the face of risk factors of the COVID-19. Also, the social protection programs should become a vital tool for policymakers and supporting the vulnerable groups using the capacity of the community and international cooperation to develop a vaccine, which is difficult to procure due to the sanctions.

J Nurs Meas 2021 Dec 13;29(3):441-461. Epub 2021 Sep 13.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran

Background And Purpose: The purpose of this research was to evaluate the psychometric properties of hospital preparedness instruments in biological events. The nsensus-based tandards for the selection of health easurements struments (COSMIN) checklist has been used to design the appropriate hospital preparedness instruments in these events.

Methods: A systematic search was performed in PubMed, Scopus, Web of Science and ProQuest, Google Scholar for relevant literature until December 31, 2018, and the data were extracted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The quality of the identified studies was assessed per measurement property according to the COSMIN checklist. Twenty studies that met the inclusion criteria were included.

Results: The result showed that none of the evaluated checklists and instruments included all dimensions required for an appropriate hospital preparedness evaluation. The results revealed that none of the included studies reported adequate information on all the measurement properties of the instruments studied as per the COSMIN criteria.

Conclusions: The information on their measurement properties was lacking. Thus, there was a need for evaluating measurement. However, a vital necessity is felt for developing an instrument with acceptable psychometric properties for measuring hospital preparedness in biological events. The present study provided improved clarity about the quality of currently available hospital preparedness instruments in the biological event and the results of this systematic review could be used to prepare a standardized instrument to evaluate hospital preparedness in biological disaster.

J Educ Health Promot 2021 30;10:258. Epub 2021 Jul 30.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

The Emergency Medical Services (EMSs) are in the frontline between the health-care systems and people in emergencies and disasters. With the increase in the frequency of natural or man-made disasters around the world, the need for prepared EMS services is increasing. This study aimed to evaluate the current disaster preparedness status of the EMS agencies in the literature and exploring the key preparedness elements and the strategies to improve the EMS disaster preparedness. The electronic database such as PubMed, Web of Science, Scopus, and Google Scholar was searched from 2000 to 2019. The searching keywords included: "EMS," "Disaster," "Preparedness," "Emergency" "Preparedness," "Disaster Preparedness," "Readiness," and the terms related to "disaster types" were used in combination with Boolean operators OR and AND. Out of 1412 articles, 7 articles were included in the review. The most important elements of the EMS disaster preparedness include the size and scope of the incident, surge capacity, planning, communication, training and education, policymaking, financial support, coordination, safety and security, early warning system, disaster response experience, and legal considerations. This systematic review showed that the EMS agencies in the world generally are inadequately prepared for an effective response to major emergencies and disasters. This study provides valuable information to EMS educators, EMS administrators to adopt and perform appropriate activities to improve the EMS disaster preparedness.

Facile provision of CuO-Kaolin nanocomposite for boosted sonocatalytic removal of Cr(VI) from hydrous media.

Environ Technol 2021 Sep 10:1-12. Epub 2021 Sep 10.

Department of Environmental Health Engineering, School of Health, Guilan University of Medical Sciences, Rasht, Iran.

Nowadays, nanoscale materials have been widely applied in the removal of contaminants from the water system. Reduction of Cr(VI) (as a poisonous species) to Cr(III) (as a slight toxic species) was performed using CuO-Kaolin with ultrasound (US) irradiation. The CuO-Kaolin nanocomposite was synthesized via a facile co-precipitation method. Then X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope and Energy dispersive X-ray spectroscopy analyses were performed to identify the structural features of CuO-Kaolin. The role of influential parameters for the reduction of Cr(VI) was investigated in sonocatalytic advanced oxidation system. About 89.35% of Cr(VI) was removed via US/CuO-Kaolin process after 90 min at optimum conditions (pH = 3, sonocatalyst dosage = 1 g L and [Cr (VI)] = 20 mg L). This outstanding result was due to the synergistic effect of the increased electron delivery to conduction band on CuO-Kaolin nanocomposite and the increased reactive surface region of nanoparticles by sonication. The presence of HO as an amplifier improved the removal efficiency of Cr(VI) from 89.35% to 100% after 20 min. Kinetic experimental results were well described by a pseudo-first-order kinetic model. Desorption experiments showed excellent stability of sonocatalyst during the reaction and maintenance of the catalytic activity up to 10 sequential cycles.

Investigating the effects of dust storms on morbidity and mortality due to cardiovascular and respiratory diseases: A systematic review.

J Educ Health Promot 2021 31;10(1):191. Epub 2021 May 31.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

New epidemiological studies acknowledge the detrimental effects of dust storms on health. The aim of this study was to systematically review the effects of dust storms on the morbidity and mortality rates of cardiovascular and respiratory diseases. The results of this study were obtained based on articles published in English-language journals. For the purpose of this study, all articles published until the end of 2020 based on the search in the "Scopus," "Web of Science," and "PubMed" databases were selected. Articles were searched independently by two trained researchers. Dust storms are the cause of many diseases and health-related complications, of which cardiovascular and respiratory diseases are common. It is necessary to recognize and investigate the harmful effects of dust storms to prevent serious harms to human societies. In the reviewed articles, the impact of dust storms on several diseases, including cardiovascular and respiratory diseases, has been analyzed. Most of these articles acknowledge the effect of dust storms on increasing the incidence and mortality rate of these diseases, although in some articles this effect is not statistically significant. Many studies conducted around the world confirm the harmful effects of dust storms on cardiovascular and respiratory diseases, including increase in the number and duration of hospitalizations, as well as increase in mortality and exacerbation of these diseases. However, some studies do not consider the harmful effects of dust storms on the above diseases to be statistically significant.

Comparison of ultrasound-accelerated versus conventional catheter-directed thrombolysis for deep vein thrombosis: A systematic review and meta-analysis.

Vascular 2022 Apr 26;30(2):365-374. Epub 2021 Apr 26.

Faculty of Pharmacy and Pharmaceutical Sciences, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.

Background: Recent in vitro and clinical studies have shown that ultrasound-accelerated catheter-directed thrombolysis (USACDT) can accelerate thrombolysis. Therefore, in this meta-analysis, we aimed to compare the efficacy and safety of USACDT with conventional catheter-directed thrombolysis in patients with deep vein thrombosis.

Methods: A systematic search of the following electronic databases was performed from their dates of inception to 20 June 2020: MEDLINE, Scopus, Google Scholar, CINAHL, Cochrane Library, and EMBASE. All randomized controlled trials that directly compared the complications and efficacy of USACDT and conventional catheter-directed thrombolysis in patients with deep vein thrombosis were identified. The statistical analysis was performed using comprehensive meta-analysis software.

Results: Finally, 18 studies with a total of 597 participants were included in our meta-analysis according to the eligibility criteria. Pooled proportion of USACDT success in patients with deep vein thrombosis was 87.8% (18 studies; 95% CI: 83.1-91.3). Success rate was significantly higher in USACDT treatment than in conventional catheter-directed thrombolysis treatment (seven studies; OR: 2.96; 95% CI: 1.69-5.16;  < 0.01)). Although the mean infusion time was higher in catheter-directed thrombolysis treatment compared to USACDT treatment, this difference was not statistically significant (three studies; MD: -1.46; 95% CI: -3.25-0.32;  = 0.10). Moreover, pooled rate of complications was lower in USACDT than catheter-directed thrombolysis which was not statistically significant (seven studies; OR: 0.49; 95% CI: 0.13-1.76;  = 0.27).

Conclusion: This meta-analysis revealed that USACDT significantly increased the success rate of thrombolysis compared to conventional catheter-directed thrombolysis. Furthermore, USACDT was associated with lower rate of complication and infusion time. Taken together, these findings confirm the superiority of this novel intervention over conventional catheter-directed thrombolysis in treatment of patients with deep vein thrombosis.

Psychological aspects of climate change risk perception: A content analysis in Iranian context.

J Educ Health Promot 2020 29;9:346. Epub 2020 Dec 29.

Department of Anesthesiology, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Risk perception is an important predictor to mitigate climate change effects which can produce mental health consequences such as anxiety and depression. For developing policies of climate risk adaptation, awareness of public attitudes, beliefs, and perception is essential. At this study, researchers tried to focus on the often "unseen" psychological aspects of climate change.

Materials And Methods: A qualitative approach was done with a consistent content analysis method. The study consisted of 33 participants including ordinary people and experts in disasters and climate change. Purposeful sampling was adopted until data saturation. The data collection was performed through in-depth and semi-structured interviews. All interviews were transcribed after listening again and again and reading several times to catch an overall understanding of the interviews.

Results: The main theme of the study was "Complexity nature of climate change risk perception" and related categories including "the Mental health dimension," "the Cognitive dimension" and "Interaction of imposed components." The structure of the research community strongly reflected effects of cultural and religious factors in all aspects of community life. Participants' life experiences of extreme events were associated to their perception of climate change.

Conclusions: Risk perception is multifactorial and complicate and should clearly be understood to improve community participation to manage climate change-related risks. We propose that authorities and related managers should pay attention to it as a priority. This may assist in developing research on public mental health practices.

Health in Emergency and Disaster Research Center, The University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

. The emergency medical service (EMS) provides first-line medical care to people who require urgent medical care in emergency and disaster situations. Preparedness is the most effective approach for the management of disaster risks, and it is essential for the emergency medical service (EMS) providers, such as paramedics, emergency medical technicians (EMT), and other EMS personnel. This systematic review will explore evidence on the preparedness of emergency medical service providers in emergency and disaster situations by reviewing peer-reviewed journal articles. . This study will be conducted on peer-reviewed articles published between 2005 and 2019 to explore the preparedness of emergency medical service providers in emergencies and disasters. Scopus, Web of Science, PubMed, and Google Scholar will be thoroughly searched to identify published studies on emergency and disaster preparedness. The following keywords will be used for searching the databases: "Medical Technician," "Paramedic," "Emergency Paramedic," "Emergency Medicine Technician," "Emergency Medical Technician," "Emergency Prehospital Provider," "Emergency Preparedness," "Disaster Preparedness," "Hospital Preparedness," "Disaster management," "Disaster Competencies," "Disaster Readiness," "Disaster," "Disaster Role," "Readiness, Preparedness, Terrorist," "Mass Casualty Incident," "Major incidents," "Mass Casualty," "Mass Gathering," "CBRNE," "Weapons of Mass Destruction," and "Chemical, Biological, Radiological, Nuclear, and Explosive Event." . To the best of our knowledge, no comprehensive review study has been conducted on the preparedness of emergency medical service providers in disaster situations. This study is the first attempt to address this gap. It will also explore the key dimensions in disaster preparedness of EMS providers and the strategies to enhance their preparedness. Identifying the key dimensions of disaster preparedness is the first step in designing and developing valid instruments to evaluate EMS provider's disaster preparedness and as well as adopting appropriate strategies to improve the level of their preparedness (This systematic review is registred in PROSPERO with CRD42020149689).

Disaster Med Public Health Prep 2020 Nov 5:1-5. Epub 2020 Nov 5.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Objective: Identification of hospital preparedness challenges against biological events such as coronavirus disease 2019 (COVID-19) is essential to improve dynamics, quality, and business continuity confidence in the health system. Accordingly, the purpose of the present study is to evaluate the challenges of hospital preparedness in biological events.

Methods: This study used a qualitative method using content analysis in which 20 health-care managers and experts who are experienced in biological events were selected through purposeful sampling. The data collection was done through semi-structured interviews, which continued until data saturation. The data were analyzed using qualitative content analysis as well as the Landman and Graneheim Approach.

Results: Six main concepts (training and practice, resource management, safety and health, patient management, risk communication, and laboratory and surveillance) and 14 subconcepts were extracted on hospital preparedness challenges in biological events through analyzing interviews.

Conclusions: The present study indicated that the health system of the country faces many challenges in response to biological events and threats. Moreover, study participants indicated that Iranian hospitals were not prepared for biological events. It is recommended to design preparedness plans of hospitals based on preparedness standards for biological events. In addition, comprehensive measures are required to enhance their capacity to respond to biological emergencies.

Associations between bone mineral density, trabecular bone score, and body mass index in postmenopausal females.

Osteoporos Sarcopenia 2020 Sep 6;6(3):111-114. Epub 2020 Sep 6.

Department of Radiology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran.

Objectives: Bone mineral density (BMD), as a gold standard determinant of osteoporosis, assesses only one of many characteristics contributing to the bone. Trabecular bone score (TBS) is applied to evaluate the microarchitecture of trabecular bone A high body mass index (BMI) has been reported to have a positive correlation with BMD. However, the relation between BMI and TBS has remained unclear Therefore, the aim of this study is to shed light on the associations between BMI, T-score, and TBS in postmenopausal women without a diagnosed underlying disease.

Methods: In this cross-sectional study, 1054 postmenopausal women were randomly recruited from the Department of Radiology, Isfahan University of Medical Sciences. Demographic characteristics and medical history of all subjects were collected from documents. TBS measurements for L1-L4 vertebrae were retrospectively performed by the TBS iNsight software using the dual X-ray absorptiometry (DXA) from the same region of spine of the subjects. The analysis was done to detect the correlation between TBS and BMI.

Results: A statistically significant negative correlation was found between TBS and BMI in patients with osteoporosis and low bone mass. In patients with normal T-scores, BMI was not significantly correlated to TBS (P > 0.05). Furthermore, there was a significant positive association between T-score and BMI.

Conclusions: Although a higher BMI had a protective effect against osteoporosis, higher BMI was associated with a lower TBS in patients with an abnormal T-score. However, BMI did not have a significant effect on TBS in patients with normal T-scores.

The association between air pollution and cancers: controversial evidence of a systematic review.

Environ Sci Pollut Res Int 2020 Nov 7;27(31):38491-38500. Epub 2020 Aug 7.

Health in Emergency and Disaster Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

There are inconsistent reports on the association between air pollution and cancers. This systematic review was, therefore, conducted to ascertain the relationship between air pollution and some cancers. This is a systematic review study, which all articles published in this area were extracted from January 1, 1950 to December 31, 2018 from Web of Science, PubMed, Scopus, Cochrane Library, MEDLINE, EMBASE, Science Direct, Google scholar. Searching was performed independently by two search-method experts. The required data were extracted from the articles by an author-made questionnaire. Forty-eight articles were investigated. Evidence linking air pollution to some cancers is limited. Leukemia had the highest association with exposure to various air pollutants and bladder cancer had the lowest association. It is noteworthy that the specific type of pollutants in all studies was not specified. Based on the findings, the results are contradictory, and the role of air pollution in some cancers cannot be supported. Accordingly, studies are recommended to be performed at the individual level or multifactorial studies to specifically investigate the relationship between air pollution and these types of cancers. In this way, the role of air pollution in the incidence of these cancers can be determined more accurately.
