Objectives Students of medical sciences are exposed to many emotional and mental problems. In light of the importance of sleep quality in learning and liveliness, this study was conducted to examine the relationship between psychological variables (stress, anxiety, and depression) and sleep quality of students. Design This research is a cross-sectional analytical study, where all students studying at Fasa University of Medical Sciences in 2012-2013 year were selected. To examine the students' stress, anxiety, and depression values, the standardized 21-item DASS-21 was used, and to examine their sleep quality, Pittsburgh Sleep Quality Index (PSQI) was used. Results The results of the study demonstrated that 73% of the students have moderate and severe stress, and 46.4% of them have PSQ scores ≥ 5. The students' mean sleep quality score was 4.65 ± 2.37, and their stress score was 8.09 ± 5.14. A statistically significant relationship was found between the students' stress levels and sleep quality (P < 0.001). Conclusion The high stress levels decrease students' sleep quality. High stress levels and also the significant relationship between stress value and decrease in students' sleep quality call for more attention to and care for students' emotional and mental issues and timely proper interference on the part of authorities.

Background and Aims Congestive heart failure is a complex multifactorial syndrome due to tissue hypoperfusion that is affected by some factors like inflammatory cytokines. In our study, we investigated the exact gene expression of three inflammatory cytokines in ischemic and idiopathic cardiomyopathy patients. Methods From 49 studied recipients in the ischemic group, 23 (46.9%) were male and from 40 studied recipients in the idiopathic dilated cardiomyopathy group, 19 (47.5%) were male. For the quantitative analysis of interleukin (IL)‐1, IL‐27, and tumor necrosis factor (TNF)‐α messenger RNAs expression level, the SYBR Green real‐time polymerase chain reaction method was performed using SYBRPremix Ex TaqTM II (Tli RNaseH Plus; Takara) and designed primers specific for each gene in an iQ5 thermocycler (BioRad Laboratories) according to the manufacturer's instructions. Results Our results showed that the expression level of IL‐1 and TNF‐α were significantly higher in the ischemic patients compared to healthy controls ( p < 0.001, p < 0.01, respectively); also, we found higher levels of IL‐1 and IL‐27 gene expressions in idiopathic patients compared to healthy controls ( p < 0.001, p < 0.001, respectively). There were not any significant differences in IL‐1, IL‐27, and TNF‐α expression levels between ischemic patients and idiopathic ones. Conclusion Although we would introduce IL‐1, IL‐27, and TNF‐α as effective inflammatory cytokines on myocardial functions in ischemic and idiopathic cardiomyopathy patients, there is not any difference between these two groups in gene expression of three main inflammatory cytokines.

Background: Identification of the role of factors such as self-esteem and self-efficacy and the investigation of their relationship among students can bring about improvement of educational planning and enhance the teaching outcome. This study aimed at investigating the relationship between self-esteem and self-efficacy among the students of medical sciences.Methods: The present study is an analytical-descriptive which was conducted as a cross-sectional study on 394 students of Fasa University of Medical Sciences in 2016. In order to collect the data two questionnaires were used namely, Coopersmith Self-Esteem Inventory (CSEI) and Rogers Self-concept Questionnaire. The data were analyzed using SPSS 22. The researchers used descriptive and inferential statistics such as t-test, chi-square one-way ANOVA, and correlation to analyze the data.Results: The mean and the standard deviation of self-esteem scores of female and male students were 38.23±6.80 and 37.51±6.67 respectively. The mean and the standard deviation of self-concept scores of female and male students were 9.49±3.53 and 9.43±4.14 respectively. The mean of self-concept scores of students of different majors had statistically significant difference with each other (0.011), whereas there was no statistically significant difference in self-esteem scores among students with different majors (0.442).Conclusions: Considering the statistically significant difference in students’ self-concept scores in different majors, it is suggested that we take right approaches to the improvement and enhancement of individuals’ self-concept and the creation of positive feedback.

Article Info Background:Among the most common occupational hazards threatening healthcare workers are needle stick injuries, injuries caused by sharp and cutting instruments, and contact with infectious pathogens transmitted by blood. This study aims to determine the prevalence and associated factors of needle stick injuries, injuries caused by sharp and cutting instruments,as well as blood and body fluids affecting healthcare workers. Material and Methods: This research adopted a descriptive cross-sectional approach in which all healthcare workers at the two training hospitals affiliated with Fasa University of Medical Sciences were selected in 2017. After receiving ethical approval (IR.FUMS.REC.1396.243), the data collected by the researcher using a questionnaire and proportional sampling. The validity and reliability of the questionnaire were confirmed prior to use. Data analysis was performed by SPSS Statistics V22.0, using mean, frequency, and a Chi-Square test. Results: According to the results of this study, 51.0% of the staff had experienced at least an injury caused by cutting tools, and 26.7% of them considered carelessness as the main cause of the injury. Nurses had the highest prevalence (24.4%) of the experience among other staff. Conclusions: The results imply that injuries caused by needles and sharp objects need more attention. In addition, improper reactions at the time of the injuries necessitate educating healthcare workers and increasing their knowledge about the dangers posed by these injuries

Objective: Congestive Heart failure (CHF) is a complex multifactorial syndrome due to tissue hypo perfusion that is affected by some factors like inflammatory cytokines. In our study we investigated the exact gene expression of three inflammatory cytokines in ischemic and idiopathic cardiomyopathy patients.Materials and Methods: From 49 studied recipients in ischemic group, 23 (46.9%) were male and from 40 studied recipients in idiopathic dilated cardiomyopathy group, 19 (47.5%) were male. For the quantitative analysis of Interleukin (IL)1, IL-27 and TNF-α mRNAs expression level, the SYBR Green Real-Time PCR method was performed using SYBRPremix Ex TaqTM II (Tli RNaseH Plus) (Takara, Japan) and designed primers specific for each genes in an iQ5 thermocycler (BioRad Laboratories, USA) according to the manufacturer’s instructions.Results: Our results showed that the expression level of IL-1 and TNF-α were significantly higher in the ischemic patients compared to healthy controls (P<0.001, P<0.01, respectively); also we found higher levels of IL-1 and IL-27 gene expressions in idiopathic patients compared to healthy controls (P<0.001, P<0.001, respectively). There were not any significant difference of IL-1, IL-27 and TNF-α expression levels between ischemic patients and idiopathic ones.Conclusion: Although we would introduce IL1, IL-27 and TNF α as effective inflammatory cytokines on myocardial functions in ischemic and idiopathic cardiomyopathy patients; there is not any difference between these two groups in gene expression of three main inflammatory cytokines.
