Chronic alcohol ingestion causes sexual dysfunction, impairs sperm motility and fertility, and changes semen quality. Considering the key role of epididymis in sperm development, the aim of the present study was to evaluate the effects of long‐term ethanol consumption on epididymis changes, including alterations in β‐defensin isoform gene expression, oxidative stress, and pathological changes, such as cell proliferation and fibrosis in the epididymis of rats. In this study, male Wistar rats were equally divided into control and ethanol (4.5 g/kg BW) groups. After six weeks of treatment, the results revealed the proliferation of epididymis cells, fibrosis in the epididymis tissue, and a significant rise in the level of 8‐OHdG and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase in the ethanol group, compared with the control group. Moreover, the ethanol group showed an increase in the gene expression of epididymal β‐defensin isoforms 15 and 21 and a reduction in the gene expression of β‐defensin isoforms 27 and 30, compared with the controls. These findings indicate that ethanol‐induced epididymal damage and sperm abnormalities might be partly associated with changes in β‐defensin isoforms and epididymal structure, mediated by the increased activities of 8‐OHdG and NADPH oxidase.

Objective:There are two basic ways to analyze survival data including nonparametric and parametric methods. Considering that cervical cancer is the fourth most common cancer among women, this study was conducted using a suitable regression model for survival data for patients with cervical cancer in Urmia.Material and Methods:In this historical retrospective study, all patients with cervical cancer who referred to Motahhari Hospital of Urmia during 2004 and 2015 were included in the study and consisted of 109 women with cervical cancer. The data were collected using checklist which filled with records of patients. The data were described with percent, mean and standard deviation. The survival function was computed with the Kaplan-Meier method. The adjusted Hazard Ratio for variables were estimated after fitting the Cox proportion hazard model using Forward Stepwise Likelihood Ratio method with PE=0.1, PR=0.15.Results:Of the 109 patients, the mean (SD) time of diagnosis was 50.1% (11.7) years. The mean (SD) and median of follow-up time was 38.23 (32.50) and 27.1 months (Mim: 2 months and Max: 132 months). Ninty-Three of patients (88.7%) were in urban area. Using Log-Rank test, the mean score of survival in patients with recurrence of 38.8 months was significantly lower than those without recurrence (102.5 months) (P <0.001). The results of the COX model showed that the adjusted relative risk of mortality with a diagnostic age of 50 years or more compared to those under 50 years of age was 1.978. The risk for marriage under age 20 was 3.189 compared to the marriage age of 20 years or more.Conclusion:According to results, the low age of marriage increases the occurrence of advanced stages of cancer in older ages and as a social and cultural factor has a significant effect on the survival of patients with cervical cancer.

Background: Depression is characterized by decreased tendency to work, reduced pleasure from work, increased or decreased weight, increased or decreased appetite, insomnia or narcolepsy, irritability, fatigue, loss of energy, feelings of worthlessness, feelings of guilt, reduced ability to concentrate and think, and thoughts of suicide or actual suicide attempts. In this 2016 study, we examined the factors and prevalence of depression in students at Urmia University of Medical Sciences in Urmia, Iran. Methods: This cross-sectional study was conducted on 400 students. Data were collected through the Beck Depression Inventory II (BDI-II): a 21- item standard questionnaire in multiple-choice format to evaluate depression. The questionnaires were distributed randomly by trained students over a period of 5 months. Data were analyzed using SPSS ver. 19 software and by descriptive statistics, independent t-tests, logistic regression models, and the chi-squared test. Results: The mean BDI score was 14.67 ± 11.30. Of the study population, 278 (69.8%) were men and 120 (30.2%) were women. In terms of depression, 40.2% of the students were in the normal range and had no depression, 23.6% were slightly depressed, and 18.3% were partially depressed. Also, 6.03% of students had severe depression, and 3.51% of students had very severe depression. No statistically signi cant relationship was observed between depression and sex (P = 0.11). However, signi cant relationships were observed between depression and education level (P = 0.001), smoking history (P = 0.001), and age (P = 0.023). P values less than 0.05 were considered statistically signi cant. Conclusion: The prevalence of different degrees of depression in the plurality of students at Urmia University of Medical Sciences necessitates the development and institution of psychological training classes.

Background: Cervical cancer is the fourth most common cancer among women and the seventh most common worldwide. Objectives: The present study aimed at investigating the usability of cure models in analyzing patients' survival. Besides, the factors affecting the long-term and short-term survival of the patients were determined, using Weibull, log-logistic, and log-normal models. Methods: The sample population of the study included 109 female patients with cervical cancer referred to Motahhari Hospital of Urmia (West Azerbaijan province) from 2004 to 2015. The cure survival analysis was used to determine the patients' survival. Results: The mean and standard deviation age at diagnosis was 50.1 ± 11.7 years. The patients' age, age at marriage, and the disease relapse were significant in the single-variable model on the long-term survival function of the patients. Moreover, the findings showed that Cured Log Logistic Parametric Model was more suitable for analyzing survival data in West Azerbaijan Province, Iran. The relapse variable was significant for all the parametric models. Conclusions: Given the divided sample population into immune and susceptible groups, the mixture cure models can be used to analyze the long-term and short-term survival of the patients with cervical cancer. Moreover, these models can be used to recognize the factors affecting both groups simultaneously.

Background: Nurses' adherence to ethical values in the field of patient care is affected by various factors, especially moral intelligence. The role of moral intelligence on professional commitment is an issue leading to improving the quality of services and health promotion. The aim of this study was to investigate the predictive power of moral intelligence on professional commitment of nurses. Method and Materials:This descriptive-analytical study was carried out on 100 nurses and 300 patients selected by stratified random sampling. Data were collected using the Lenik & Kiel moral Intelligence Questionnaire and Nurse Professional Commitment Questionnaire. Data were analyzed using descriptive analysis and regression. Results:The results showed that there was a significant statistical relationship between moral intelligence and professional commitment (P=0.001). There was a significant relationship between demographic variables, age and work experience with moral intelligence and two variables of gender and professional commitment (P <0.05). In addition, regression showed that dimensions of nurses 'moral intelligence account for 41% of the variance of nurses' professional commitment. of the four dimensions of nurses' moral intelligence, compassion had the most significant effect (P=0.03, β=0.32). Conclusion:The results of this study showed that moral intelligence is associated with professional commitment and is able to predict it. Therefore, it is recommended that nursing managers and authorities to put the Strengthening nurses' moral intelligence in the list of their priorities.
