Because of moving away from family, living with other students, academic atmosphere pressures and uncertain future, students are often in risk of depression. This study was done to determine prevalence and related factors of depression in students of Arak, Iran. Materials and Methods: This analytical cross-sectional study was carried out on 304 undergraduate medical and basic students in Arak universities, from May to July 2008. General Health Questionnaire -28 question (GH-28) has been used for data gathering and analyzed by T-test, chi2 and logistic regression tests. Results: Mean of students' general health was 26.18±11.02 and 52.3% of students were scored above the threshold of GHQ- 28, that indicating depression. Female sex, major uninteresting, uncertain future and positive family history were the most important risk factors of depression but significant relationship between age, education Course and year were not seen. Conclusion: The prevalence of depression was higher than society and in girls is more than boys students. But there wasn’t any difference between medical and non medical students. So attention to financial and occupational future of graduated and under graduated students is essential.

Abstract Background: Educational decline is one of the most important problems in educational institutes. There for, present study was aimed to survey frequency of educational decline and some effective factors of student’s opinion in Arak University of Medical sciences, 2009. Materials and Methods: In a analytical cross sectional study, 600 students passing at least one term of their course in Arak university of medical science in 2009, were determined by questionnaire and interview. After data gathering, students divided two groups, successful and non successful base n educational average and failed terms and then data were analyzed and determined frequency and some effective factors on it. Results: Decline education frequency is 19% and there were significant difference between sex, marital status, average score diploma, educational level of father, hesitancy, gap between diploma and university admission and course satisfaction between two groups of successful and unsuccessful students (P<0/05). However, no significant correlation observed in age, course, family economic status and mother’s job (p>0/05). Also, most of effective problem solutions in student’s viewpoint are included admission in university base on diploma average score and use of expert consular. Conclusion: Educational managers should be considering effective variables on performance and educational decline in students, in order to identifying high risk students and providing better facilities for them by appropriate consulting.

Background: Nowadays, scientific religion studies using the commonly accepted methods in human sciences is one of the new, interesting research areas in scientific and academic research. Noticing the importance of religion in student’s mental health, this study was designed and conducted. Materials and Methods: In this Cross-Sectional study, 310 students at Arak University of Medical Sciences were randomly surveyed through demographic, Khodayary Fard’s religious attitude, and GHQ-28 questionnaires. Data were analyzed via descriptive statistics, Chi square, and Pearson-product correlation through SPSS software. In all stages of the research, ethical issues in research were taken into consideration. Results: The mean and standard deviations of age, GHQ, and religious attitude were 21.29±2.22 years, 24.04±9.41, and 81.04±11.9, respectively. In terms of religious attitude, 1.4% (4 students) had weak, 12.5% had moderate, and 86 % (240 students) had strong attitudes. A positive relationship was observed between religious attitude and mental health. Also, there was a significant inverse relationship between religious attitude and age, major, place of living, and mother’s level of education (p<0.05). Conclusion: In this study, the majority of the students had strong religious attitudes and a significant positive correlation was found between the students’ religious attitude and mental health. Improving religious attractions through educational, religious, cultural programs for enhancing the religious attitudes of students is suggested.

Background and Aim: Opioid and benzodiazepine family drugs are concurrently used in various patients. Considering the respiratory depressant effects of both classes, in this study, we investigated the effect of coadministration of morphine and several widely used benzodiazepines in the clinic on the rate of respiratory depression in rats.
Methods & Materials: Seventy adult male Wistar rats were randomly divided into 10 groups; morphine, midazolam, diazepam, lorazepam, alprazolam, morphine-midazolam, morphine-diazepam, morphine-lorazepam, and morphine-alprazolam. Respiration signal was recorded using whole-body plethysmography 15 minutes after the intraperitoneal injection of the drugs. The respiratory pattern was examined using several parameters; the mean value of inter-breath interval and the respiratory rate, as well as the coefficient of variation and sample entropy analysis of inter-breath interval.
Ethical Considerations: This study was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1397.327).
Results: Analyzing respiratory data revealed that injecting the anxiolytic dose of alprazolam, and the combination of morphine-alprazolam and morphine-midazolam, altered the respiratory pattern. Such changes were associated with a decrease in the number of breaths and an increase in the inter-breath interval in the explored test animals, compared with the controls. The obtained data also indicated that morphine-midazolam injection increased the variability of the breathing pattern; such an alternation was associated with increased irregularity and decreased coefficient of variation of the inter-breath interval.
Conclusion: The present research results suggested that the short-term injection of morphine-midazolam changes the respiratory pattern more severely than morphine combined with other benzodiazepines.

Introduction: The emergency department is an essential part of the health care system in any country, providing 24-hour service to patients requiring urgent medical, surgical, or other care. The main aim of the present study was to determine the epidemiological characteristics of patients referred to the emergency department at the referral center in Arak city.
Methods: The present cross-sectional study was conducted on 226,127 patients referred to the emergency department during 2020-2023. The information in this study was based on the registration system of patients referred to the emergency department in Vali-asr Hospital in Arak. Data analysis was done by using descriptive statistics and t-test and Chi-square statistical tests. The significance level of the tests was considered P < 0.05.
Results: The mean (standard deviation) age of patients was 36.3 (20.5) years with an age range of (1-103). 147,088 patients were male (65%). Death occurred in 2,633 (1.2%) patients. More than 50% of patients were referred between 8:00 AM and 4:00 PM. Hospital admission was required for 32.1% of patients. 63% underwent surgical procedures. A statistically significant association was observed between gender, age, year of visit, season, time of visit and surgical procedures with the type of admission and the condition of the patient at the time of discharge (P < 0.05).
Conclusions: Understanding the epidemiology and the demographic and clinical characteristics of patients can facilitate timely planning for staff deployment and resource allocation. This can help prevent overcrowding, improve patient outcomes, and increase patient satisfaction through effective management.
