Aim Job stress is a part of nurses' professional life that causes the decrease of the nurses' job satisfaction and quality of work life. This study aimed to determine the effect of positive thinking via social media applications on the nurses' quality of work life. Methods This was a pretest-posttest quasi-experimental study design with a control group. The samples were selected among the nurses in two hospitals in Fasa University of Medical Sciences and divided randomly into two interventional (n = 50) and control (n = 50) groups. Positive thinking training through telegrams was sent to the intervention group during a period of 3 months. Data were collected by using Brooks and Anderson's questionnaire of work life quality and analyzed by SPSS 18. Results The mean total scores of pretest and posttest in the intervention group improved noticeably and there were significant differences between mean scores of quality of work life in pretest and posttest scores in interventional groups (p < 0.001) and in dimensions of work life quality, home life (p < 0.001), work design (p < 0.001), work context (p < 0.001), and work world (p = 0.003). Conclusion This study concluded that positive thinking training via social media application enhanced nurses' quality of work life. This study is necessary to carry out on a larger sample size for generalizing findings better.

BackgroundSome epidemiological evidence has shown a relation between ambient air pollution and adverse health outcomes. The aim of this study was to investigate the effect of air pollution on mortality from respiratory diseases in Tehran, Iran.MethodsIn this ecological study, air pollution data was inquired from the Tehran Province Environmental Protection Agency and the Tehran Air Quality Control Company. Meteorological data was collected from the Tehran Meteorology Organization and mortality data from the Tehran Cemetery Mortality Registration. Generalized Additive Models (GAM) was used for data analysis with different lags, up to 15 days. A 10-unit increase in all pollutants except CO (1-unit) was used to compute the Relative Risk of deaths.ResultsDuring 2005 until 2014, 37,967 respiratory deaths occurred in Tehran in which 21,913 (57.7%) were male. The strongest relationship between NO2 and PM10and respiratory death was seen on the same day (lag 0), and was respectively (RR = 1.04, 95% CI: 1.02–1.07) and (RR = 1.03, 95% CI: 1.02–1.04). O3 and PM2.5 had the strongest relationship with respiratory deaths on lag 2 and 1 respectively, and the RR was equal to 1.03, 95% CI: 1.01–1.05 and 1.06, 95% CI: 1.02–1.10 respectively. NO2, O3, PM10 and PM2.5 also showed significant relations with respiratory deaths in the older age groups.ConclusionsThe findings of this study showed that O3, NO2, PM10 and PM2.5 air pollutants were related to respiratory deaths in Tehran. Reducing ambient air pollution can save lives in Tehran.

Non-alcoholic fatty liver disease (NAFLD) is an example of pathological fat accumulation in the liver and one of the major health conditions in the world. This study aimed to examine the independent role of dietary patterns in the development of NAFLD. In a cross-sectional study, 1500 individuals referred to a nutrition clinic were randomly selected, their demographic, anthropometric and blood metabolic indices were obtained, and food frequency questionnaires were completed for them. Liver stiffness was calculated using the NAFLD score formula and fibroscan. The two dominant dietary patterns identified were the “healthy” and “unhealthy dietary patterns”. A significant percentage of those with NAFLD (45%) were in the upper quartile of the unhealthy model; however, only 10% had the healthy pattern (p < 0.001). In this study, 32.9 and 13.9% of the healthy and unhealthy participants were in the upper quartile of the healthy diet pattern. Also, it was shown that waist circumference is a strong mediator of dietary patterns and NAFLD relationship, and the indirect effect of diet through abdominal circumference is 28 times greater than the direct effect on NAFLD. The results suggested that healthy and unhealthy dietary patterns are respectively associated with lower- and higher-risk of NAFLD but the role of waist circumference as a mediator deserves more consideration.

BACKGROUND:Health literacy is a combination of reading and listening skills, data analysis, decision-making, and the ability to implement these skills during the necessary health situations. This study was conducted with the purpose of determining the effect of educational intervention on health literacy and its impact on health-promoting behaviors of the health ambassadors in the health and treatment centers of the health network in Kazeroon (Fars province, Iran).MATERIALS AND METHODS:The present study is a quasi-experimental study using before-after test procedure on 256 health ambassadors. Random systematic sampling method was used and to assess the health literacy, Montazeri's health questionnaire was used, also the standard questionnaire (health-promoting lifestyle profile-I) was applied to determine the status of the health-promoting behaviors. Two questionnaires were filled out by the health ambassadors before and following the intervention. Data analysis was performed using SPSS software 22, through t-test, ANOVA, and Pearson correlation.RESULTS:The mean health literacy scores of the ambassadors before educational intervention were 79.22 which increased to 95.49 after intervention. Moreover, the results of the study showed a direct significant correlation of health literacy with all the dimensions of health-promoting behavior questionnaire before and after the intervention (P < 0.001).CONCLUSIONS:Educational interventions can be used to enhance the health literacy of health ambassadors and have a significant impact on improving health-promoting behaviors.

ObjectiveDepression is a major risk factor for suicide and more than 90% of people who attempt suicide suffer from depression. The present study aimed to investigate the effect of eye movement desensitization and reprocessing (EMDR) therapy on the severity of suicidal thoughts in patients with major depressive disorder.Study designRandomized Clinical Trial.MethodsThis clinical trial was performed on 70 people with major depressive disorder who exhibited suicidal thoughts. The patients were selected via convenience sampling and were randomly divided into control (n=35) and experimental (n=35) groups. EMDR was performed individually in the experimental group for 45–90 min, 3 days per week, on alternate days, for 3 weeks (9 sessions in total), whereas the controls group received routine treatment without intervention. Both groups completed the Beck Scale for Suicide Ideation (BSSI) at pre- and post-test. The obtained data were analyzed with descriptive and inferential statistics using SPSS 22 (α=0.05).ResultsMean BSSI score for the experimental group was reduced significantly at post-test (11.11±4.15) compared to pre-test (26.48±5.74) (p<0.001). Although the control group’s mean BSSI score was also reduced at post-test (24.93±4.42) compared to pre-test (26.68±5.05), this difference was not statistically significant (p>0.05).ConclusionEMDR therapy has been shown in this study to reduce the severity of suicidal feelings. Therefore, it can be recommended as an alternative treatment method for reducing the severity of suicidal thoughts in patients with major depressive disorder.
