ContextIn spite of the high prevalence and consequences of much workplace violence against emergency medical services personnel, this phenomenon has been given insufficient attention. A systematic review can aid the development of guidelines to reduce violence.ObjectivesThe research question addressed by this paper is, “What are the characteristics and findings of studies on workplace violence against emergency medical services personnel”?Data SourcesA systematic literature review was conducted using online databases (PubMed, Scopus, Google Scholar, and Magiran) with the help of experienced librarians.Study SelectionInclusion criteria comprised studies in the English or Persian language and researcher’s access to the full text. There was no limit to the entry of the study design. Exclusion criteria included lack of access to the full text of the article, studies published in unreliable journals or conferences, and studies in which the results were shared with other medical or relief groups and there was no possibility of breaking down the results.Data ExtractionA “Data extraction form” was designed by the researchers based on the goals of the study that included the title and author(s), study method (type, place of study, sample size, sampling method, and data collection/analysis tool), printing location, information related to the frequency of types of violence, characteristics of victims /perpetrators, and related factors.ResultsThe papers reviewed utilized a variety of locations and environments, methods, and instrument samplings. The majority of the studies were performed using the quantitative method. No intervention study was found. Most studies focused on the prevalence of violence, and their results indicated that exposure to violence was high. The results are presented in six major themes.ConclusionsWorkplace violence and injuries incurred from it are extensive throughout the world. The important causes of violence include the shortage of training programs dealing with violence, lack of violence management protocols, and delays in response times. Therefore, afterthought and resolve are more crucial than ever. Workplace violence reduction strategies and suggestions for future studies are also discussed.

BackgroundTrauma, in addition to economic and social costs, is the fourth cause of death in the world and in the year 2000 alone, it led to the death of more than 6000000 people. In Iran, Trauma has the first burden of disease and also needs a long medical surveillance.ObjectivesThe aim of this study was to evaluate the outcome of trauma cases using the trauma score and the injury severity score (TRISS) model and then comparing this with the results of a major trauma outcome study (MTOS) carried out in the US.Patients and MethodsThis study is a retrospective, descriptive and analytical study on 1000 patients aged 2 - 82 years old with closed or penetrating traumas staying at Ardebil Fatemi hospital. In this study, injury severity score (ISS), revised trauma score (RTS), and TRISS were calculated and patients' viability ratios were obtained.ResultsThe results showed that 714 patients (71.4%) were male and 286 patients (28.6%) female with the mean age of 35.68 years. In this study 45 (4.5%) and 955 patients (95.5%) had penetrating and blunt traumas, respectively, whereby the head and neck were the most prevalent (74%) areas of injury. The most common reason for these traumas was, accident with vehicles with 670 cases (67%), which resulted in hospitalization. From this group, ninety-seven cases (9.7%) died in the hospital. From these results, calculations of ISS and RTS were 15.50 ± 11.31 and 7.49 ± 0.79, respectively. According to the calculation of the TRISS model, 91.5% of trauma victims should be survived, while only 90.3% survived practically.ConclusionsWe can conclude that the surveillance presented to our injured group probably had some defects that need to be revised in therapeutic services to enhance survival requirements.

Background: Coronavirus disease 2019 (COVID-19) is a global public health emergency and may result in psychological problems such as anxiety and depression in general population. Therefore, this study aimed to determine the prevalence of anxiety and depression and their associated factors in general population of Iran during the COVID-19 pandemic.Methods: We conducted this web-based cross-sectional study on 5328 individuals in Iran, between 17 and 29 April 2020. Data were collected through an anonymous online questionnaire via social media like WhatsApp and Telegram. The online survey collected information on demographic characteristics, COVID-19-related variables, and anxiety and depression. Anxiety and depression were assessed using the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), respectively. Simple and multiple logistic regression analyses were performed to determine independent predictors of anxiety and depression.Results: The mean GAD-7 and PHQ-9 total scores were 7.17 (SD=5.42) and 7.80 (SD=6.68), respectively. The prevalence of anxiety, depression, and comorbid anxiety-depression were 30.1%, 33.4%, and 22.1%, respectively. According to the adjusted analysis, anxiety was significantly associated with being female, being young and middle-aged, being unemployed or housewife, having chronic diseases, long time thinking about COVID-19, having family members, friends, and/or relatives infected with COVI-19, and death of family members, relatives or friends due to COVID-19. Same results were also found for depression. Furthermore, depression was associated with being single, being resident in urban area, and having high risk individual in family. Conclusion: The prevalence of anxiety and depression were considerably high in general population of Iran during the COVID-19 pandemic. In addition, the findings suggest that more attention needs to be paid to vulnerable groups such as women, young/middle-aged adults, unemployed people, people with chronic disease. Thus, a holistic approach, including management policies, psychosocial interventions, training, support, and tele-mental health, is absolutely crucial to reduce mental health problems of the COVID-19 and any outbreaks of other infectious diseases.

BackgroundAcute myocardial infarction (AMI) is one of the most preventable non-communicable diseases in human. Identifying triggers of myocardial infarction (MI) and prevention ways of exposure-induced complications can reduce morbidity and mortality in people at risk.AimThe aim of this study was to identify the emotional, environmental, physical and chemical dimensions of acute triggers in patients with AMI.MethodsThis case-crossover study was conducted on 269 patients with AMI, hospitalized at two remedial centers in Rasht in 2015. The study samples were selected by convenient sampling method. Data were collected using researcher-made questionnaire through interviews. Hazard and control periods for each trigger and its effects on the development of MI were studied. The collected data were analyzed using descriptive and analytical statistical methods, Cochran test, and generalized estimating equation (GEE) model with logistics function default in SPSS version 21, and p < 0.05 was considered statistically significant.ResultsThe results showed that quarrel (P = 0.008, OR = 2.01) and hearing the sudden news (P = 0.001, OR = 2.19) were the most common emotional triggers. Respiratory infections (P = 0.0001, OR = 6.78) and exposure to hot or cold weather (P = 0.005, OR = 2.19) were the most frequent environmental triggers. Doing heavy activities (P = 0.005, OR = 1.66) and sexual activities (P = 0.003, OR = 2.36) were among the most common physical triggers. High-fat foods consumption and overeating (P = 0.0001, OR = 3.79) were the most frequent chemical triggers of AMI.ConclusionIt seems that given the importance of the triggers in the incidence of AMI, planning is necessary to train vulnerable individuals to reduce exposure to triggers.
