Introduction and Aim:Medication errors as a serious problem in world and one of the most common medical errors that threaten patient safety and may lead to even death of them. The purpose of this study was to investigate the causes of medication errors and strategies to prevention of them from nurses and nursing student viewpoint.Materials & Methods:This cross-sectional descriptive study was conducted on 327 nursing staff of khatam-al-anbia hospital and 62 intern nursing students in nursing and midwifery school of Zahedan, Iran, enrolled through the availability sampling in 2015. The data were collected by the valid and reliable questionnaire. To analyze the data, descriptive statistics, T-test and ANOVA were applied by use of SPSS16 software.Findings:The results showed that the most common causes of medications errors in nursing were tiredness due increased workload (97.8%), and in nursing students were drug calculation, (77.4%). The most important way for prevention in nurses and nursing student opinion, was reducing the work pressure by increasing the personnel, proportional to the number and condition of patients and also creating a unit as medication calculation. Also there was a significant relationship between the type of ward and the mean of medication errors in two groups.Conclusion:Based on the results it is recommended that nurse-managers resolve the human resources problem, provide workshops and in-service education about preparing medications, side-effects of drugs and pharmacological knowledge. Using electronic medications cards is a measure which reduces medications errors.

Background: Olive (Olea europaea), from the Oleaseae family, is a very popular plant for its biological and pharmacological characteristics. Olive tree derivatives possess antioxidant, anti-inflammatory, antihyperlipidemic, and cardioprotective effects.

Parkinson's disease (PD) is an age-related disease in which dopaminergic neurons in the nigrostriatal pathway are destroyed, resulting in movement and behavioral problems. Oxidative stress and the generation of reactive oxygen species play key roles in neurodegenerative diseases, such as PD. Rotenone (ROT) is a common pesticide that induces oxidative stress. Olive leaves extract (OLE) has antioxidant and neuroprotective effects. Thus, the aim of this study was to investigate the neuroprotective effects of OLE on ROT-induced oxidative stress in the midbrain of a rat model of PD. Ninety-six Wistar rats were randomly divided into the following 6 groups (n = 16 rats/group): Control, Sham, ROT, and 3 ROT + OLE (75, 150, and 300 mg/kg/daily) groups. ROT (2.5 mg/kg/48 h) was injected subcutaneously, and vehicle or OLE was orally administered for 30 days. The animals were then sacrificed, and their brains were removed. Biochemical measures, including the levels of catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA), and the number of tyrosine hydroxylase (TH)-positive neurons were determined, and behavioral (rotarod and hanging) tests were conducted. The balance and muscle strength of the OLE (150 and 300 mg/kg)-treated groups were significantly improved. Treatment with OLE prevented the increases in the levels of MDA, significantly improved the SOD, CAT, and GPx levels in the midbrain, and prevented the depletion of the TH-positive neurons. These findings suggested that OLE has neuroprotective properties and that it might be useful for preventing the death of dopaminergic neurons in patients with PD.

Background: Today, the prevalence of Internet Addiction (IA) is increasing among college students and the mental health of students is reduced with the increasing severity of IA. Objectives: The aim of this study was to evaluate IA and mental health among medical sciences students in the southeast of Iran. Materials and Methods: This cross-sectional study was carried out on 417 students of Zahedan University of Medical Sciences, Zahedan, Southeast of Iran, during year 2016. The participants were recruited through a two-stage stratified sampling method. The data collection was done using Young Internet Addiction Test (YIAT) and Goldberg General Health (GHQ) standard questionnaires. Data analysis were performed by ANOVA, Pearson correlation, chi-square, and logistic regression tests using SPSS software for Windows version 16. Results: The overall prevalence of IA in students was 27.56% (95% CI: 21.3 to 30.8). The prevalence of IA was 15.82% (95% CI: 11.3 to

Introduction and Aim: Emotional intelligence is one of the most important leading factors influencing different aspects of human life. It leads individuals to percept their feelings for appropriate decision making and fields for future accomplishments. The aim of this study was to Investigation of the associations of self-assessed EI with academic achievement and general health among medical students. Materials & Methods:This cross-sectional study was conducted on 426 students of Zahedan University of Medical Sciences from October 2014 to May 2015. Random sampling method was used. Sibria Shring standard emotional intelligence questionnaire and Goldberg's standard general health questionnaire (GHQ-28) were used for data collecting. Data analysis was through descriptive statistics (mean, standard deviation) and inferential statistics (t-test, ANOVA and Pearson correlation coefficient) by SPSS v.21. The tests significant level was considered 0.05. Findings:The average total score of emotional intelligence in males (102.23±1.67) was better in comparison with females (98.54±2.23). There was not any significant difference in total mean scores of students of different fields of Study (P=0.211). According to ANOVA test, it has not observed any significant difference between scores of emotional intelligence scales of students from different domains of study. The results of Pearson correlation test confirmed a positive significant correlation between emotional intelligence, academic achievement and general health. Conclusion:According to the results of this study that has shown a significant relationship between emotional intelligence, general health and academic achievement, it is needed to hold some workshops and classes for emotional intelligence improvement.
