Background and Objective : Recirculation rate is essential for the quality of Hemodialysis . Since the treatment of patients is based on the Dialysis Adequacy, the evaluation of recirculation is especially important. This study was performed with the aim of measuring arteriovenous fistula recirculation and its relationship with some factors in Hemodialysis patients.

  Material and Methods: In this Descriptive-Analytical study, all Hemodialysis patients (n=100), in Panje Azar Hospital of Gorgan, whose vessels were accessed by arteriovenous Fistula was studied in the summer of 2009. In order to determine recirculation rate ، we used urea based classic method. The cut point of recirculation was considered 10%. The variables studied are Fistula longevity ، direction of needle insertion ، the space between needles and the place of needles fistula and KUF filteration. Data were analyzed by using descriptive statistics and logistic regression test (odds ratio and ci reported) in the SPSS software.

  Results: Patients were male (53) and female (47) with the mean age of 50.93± 17.23. The mean year of Dialysis history was 4.04 ± 5.04. Fifteen percent of patients had recirculation. Average access recirculation of all patients was 0.067 ± 0.118. Recirculation rate had significant relationship (P <0­.­05) with direction of two Arterial-Venous needle and the place of the two needles ، which may have been higher.

  Background and Objective : Human resources are the most valuable sources of an organization. Nurses, because of special nature of their job, are influenced by various stressors affecting on their job satisfaction and organizational commitment. The aim of this study was to compare Nurses’ job satisfaction and their organizational commitment in intensive care and general wards of Golestan University of medical sciences.

  Material and Methods: In this descriptive & analytical study, 389 Nurses were selected via census sampling in 1387. The instrument were job satisfaction questionnaire reliabled by alpha chronbach and meyer organizational commitment scale.To analyze the data, we used Pearson correlation coefficient, independent test, regression and one way anova in spss 16 soft ware environment.

  Results: Participants were between 22-55 years. Their mean age was 32.6 ± 7.4 and most of them (72.7%) were female. Intensive care and emergency wards’ Nurses had the lowest organizational commitment and job satisfaction, respectively. There was a significant relationship between job satisfaction and organizational commitment in studied wards (P<0.05).

  Background and Objective: Student's ­ mental ­ health­ is one of the effective factors on academic achievement and it seems that the experience of university environment leads to some changes in it. The aim of this study was the assessment of Golestan medical university students' mental health, when they enter university and after one year.

  Material and Methods: In this descriptive and analytical study,the mental health of 132 students of Golestan university of medical sciences were measured in two times. The first was in entrance to university and the second was after one year.The date was gathered by a demographic data sheet and general health questionnaire (GHQ-28). Statistical analysis was done in SPSS­-16 software environment,using descriptive statistics, spearman correlation coefficient, paired T-­test and independent T-­test.

  Results: The subjects aged19.89 ± 1.22 are both boys(n=43,32.6%) and girls(n=89,67.4%). In entrance to university, 22% of students are indicaled as an inappropriate mental health.Paired­ T-test indicated that students' total mental health score and its subscales (somatic symptom, anxiety and sleep disorder, social dysfunction and depression) has no significant difference in two measurements­(P>0.05).Based on independent T-test, the second measurement of mental health is not significant between dormitory residents and non dormitory students, and between native and nonnative students (P>0.05).

   Conclusion: According to our finding, in first year of university, student's mental health has no special changes. Small sample size and lack of follow up in later years of university can be our study limitation.

  Background and Objective: Cardiac angiography, which is widely used in Iran, is a diagnostic and therapeutic procedure for cardiac diseases. The patients suffer from back pain due to complete bed rest after angiography. Thus, this study aimed at determining the correlated factors with the severity of back pain after cardiac angiography in Dr. Ganjavian Hospital of Dezful­, 2011.

  Material and Methods: In this correlational study, 140 candidates of cardiac angiography were selected via convenience sampling. We used a checklist to collect the data about age, sex, body mass index(BMI), smoking, high blood pressure, diabetes and duration of angiography, which are the influential factors of the severity of back pain. Then, the severity of back pain was measured at first, second, fourth and sixth hour after angiography, using a numerical scale of pain assessment.­­To analyze the data, we used descriptive statistic, Mann Whitney and Spearman correlation.

  Results: ­The subjects are males (N=67), females (N=64) and smokers (­12%). The mean age is 55.7±7.7, and body mass index is 27.6±3.07. None of them has history of back pain and previous angiography. Based on Spearman, there is no significance correlation between back pain of 1, 2, 4, and 6 hours after angiography and factors such as age, BMI and duration of angiography. Man Whitney test indicates a statistical significance between gender and severity of pain in the first hour (Z=-2.17) and sixth hour (Z=-2.4) after angiography, whereas there is no statistical significance in the second, fourth and fifth hour after angiography.­ As well, there is no significant correlation between back pain and variables such as smoking, diabetes and hypertension.

  Conclusion: The findings showthat the nurses by being aware of related factors to back pain severity can try to reduce the pain and promote the patients’ convenience.

  Background and Objective: Injection of subcutaneous low molecular weight heparin often causes some local reactions such as ­bruising, hematoma­, and pain, directly related to inappropriate injection method­. This study aimed at determining the effect of injection duration of­ Subcutaneous Enoxaparin Sodium on the size of bruising and the severity of injection pain.

  Material and Methods: This experimental study was conducted on 36 patients medicated by subcutaneous Enoxaparin Sodium (60mg). ­­They were randomly divided into two groups.­ The first group received routine method of subcutaneous anoxaparine injection (10 second duration injection technique) and in the second group in addition to routine method, ­“10 second waits” before removing needle was performed. Data collection was carried out by using a researcher-made check-list consisting of a section for demographic data and a section to record the extent o f bruising and pain intensity.­ The Extent of bruising was measured by using a clear flexible ruler within 24, ­ 48 and 72 hours and pain intensity by visual analog scale (VAS) ,immediately after injection­.­­We analyzed the Data by independent T test and Chi square.

  Results: ­ The ­Results indicate ­­that­ the mean ­of pain intensity in second group (­3.05 ± 1.71­)­ is less than first group (­3.86 ± 2.75­)­.­There is no significant difference between two groups for the extent of bruising in 24, ­ 48 and 72 hours (P>0.05).

  Conclusion: with regard to ­pain intensity and the size­ of the bruising, the two groups are not significantly different.

Background and Objective: The usual method of assessing depth of anesthesia, which is not sensitive and specific enough, is measuring hemodynamic parameters, autonomic changes and subjective symptoms including movement, sweating and lacrimation. This study aimed to determine the relationship between the depth of anesthesia and hemodynamic indices.

Material and Methods: This correlational study was conducted on 57 patients undergoing elective hernia surgery in Shahid Beheshti Hospital ,Sabzevar in summer 2014.  An identical anesthesia technique was used for all patients.  Depth of anesthesia was monitored quantitatively by bispectral index (BIS) at 5-minute intervals, with simultaneous recording of heart rate and blood pressure. We analyzed the data using Anova and correlation coefficient.

Results: The mean age was 45.54±13.46. The patients were males (n=36) and females (n= 21).   Only 59.6 % of the patients experienced a normal depth of anesthesia. Hemodynamic parameters were not significantly correlated with anesthetic depth except for heart rate in the first 5 minutes (P= 0.013).

Conclusion: Given that hemodynamic parameters have some limitations in determining the acceptable depth of anesthesia, we recommend using the monitors based on brain signal processing.
