Following the COVID-19 pandemic and the exposure of Iran's military and government services and hospital system to this disease, in this study we intend to the evaluation of COVID-19 treatment outcomes in a military hospital and its comparison with a nonmilitary hospital.

This cross-sectional study was performed on a sample of 535 patients (155 cases in a nonmilitary hospital and 380 cases in a military hospital) with COVID-19 patients admitted to the military and the nonmilitary hospital in Tehran city in 2021 who were selected using random sampling. Death, hospitalization in the Intensive Care Unit (ICU) and Average Length of Stay in Hospital (ALSH) were considered as treatment outcomes in this study. The standard checklist was used to collect data and SPSS software version 24 was used to analyze the data.

In this study, the death rate, hospitalization in ICU and ALSH in the nonmilitary hospital were 20.6%, 40.6% and 5.15±8.23 days, respectively. These three outcomes (death rate, hospitalization in ICU and ALSH) in the military hospital were 8.9%, 15.3% and 4.30±7.56 days, respectively. The results of this study showed that the death rate (P<0.001) and ICU hospitalization (P<0.001) were statistically different between the two hospitals, but the two hospitals were similar in terms of ALSH (P=0.125).

Due to the difference in the type of treatment used (more corticosteroids and fewer antiviruses) in the military hospital than the nonmilitary hospital, it is possible to ensure better treatment performance in the military hospital rather than the nonmilitary hospital.

University is an institution that can help educate future managers and human developers through teaching science-trained learners. Student's assessment in the field of sciences is one of the ways to examine the effectiveness of different teaching methods and learners. The purpose of this study was to evaluate the self-assessment of students from their learning curriculum with teacher's assessment.
In this descriptive-cross sectional study, 41 undergraduate students of environmental health, Faculty of Health, Lorestan University of Medical Sciences, were selected in two different educational levels in the 2014-2015 academic year. After dividing the medical parasitology course into four parts, the methods of self-evaluation and evaluation of the teacher were investigated together and the results were analyzed by means of mean, standard deviation, correlation coefficient and significant level.
Statistical analysis showed that there is a significant difference between self-assessment of students with the points assigned by the teacher for the paradigm lesson only in the first part of the lesson and in the first semester students (p The direct relationship between these two types of evaluation suggests that it is possible to replace self-assessment of students with their own learning rather than routine evaluation methods that are time consuming, costly and anxious. Faculty members of the universities can use this method to assist the faculty in their education and, after eliminating the deficiencies, provide an appropriate assessment method.

Atherosclerosis is the most common cardiac progressive disease that begin in childhood and in the middle age it shows clinical demonstration that many factors has a role in constructing it. In this study using latent variable model to determine simultaneous effect of factors associated with blood glucose and cholesterol is done in heart patients of khorramabad. In this cross-sectional study, 251 patients who admitted in Specialize ward of cardiovascular in Shahid Madani hospital of Khorramabad in 2011 were used. Information from medical records, history and arrival tests were recorded. For identification of simultaneous risk factors associated with total cholesterol and fasting blood glucose of patients, the latent variable model with dichotomous and continuous responses was used. To analyze the data SAS software, version 9 was used. Results showed that factors effecting total cholesterol are systolic blood pressure (P=0.026), diastolic blood pressure (P=0.001), triglycerides (P=0.001), CRP (C - reactive protein) (P=0.015) and ESR (Erythrocyte Sedimentation Rate) (P=0.033). Also factors affecting blood glucose are age (P=0.001), smoking (P=0.031) and triglyceride (P=0.003). Results from this study show that controlling factors such as triglycerides, blood pressure and smoking can prevent the progression of atherosclerosis. Considering the importance of cardiovascular disease and its associated risk factors, it is essential that further studies will be carry out.

Rocker shoes are the most commonly prescribed external therapeutic shoe modification and are used for treatment of the ankle and midfoot problems. The aim of this study was to assesse the effects of the heel- to-toe rocker shoes on temporal-spatial and ankle joint moments in sagital and frontal plane. In this quasi-exprimental study, three-dimentional gait analysis was carried out on 20 healthy university female students with normal normal gait pattern selected by convenience sampling method. A Vicon 470 system(Oxford Metrix, U.K.) consisting of 6 cameras operating at 60Hz and kistler forceplate (A9286) was used.The paired samples T test was used to statistical analysis. The results showed that there is no significant change in temporal-spatial parameters while wearing this modified shoe, but the ankle moments while wearing rocker shoes in sagittal plane was significantly less than that while wearing traditional shoes(p=0.002) but in frontal plane significantly increased(p=0.007). Based on the current findings the major benefits of this modified shoe appear to be significantly restricted sagital plane moments with maintenance of walking speed so the loads on ankle joint and achilles tendon reduced, but increases frontal plain moments which leads to increase of mediolateral instability of ankle joint.

In addition to adequate nutrition and balance of nutrients in the pregnant mother's diet, maternal weight gain during pregnancy has a major impact on maternal health and fetal well-being. The purpose of this study was to compare pre-gestational BMI and gestational weight gain on GDM according to the new definition of GDM. This descriptive cross-sectional study was carried out on 18 to 35 years old pregnant women with no underlying disease using convenience sampling method In the first months of pregnancy, women's height, weight and blood pressure as well as FBS were measured.The second assessment was done in the 24th-28th weeks of gestation using repeated measurements of weight, blood pressure, and gestational diabetes screening test (GCT). The third evaluation was conducted at the end of pregnancy to measure mother and infant weight.The data was analyzed by SPSS, version 16, t-test and Mann-Whitney test. In this study, 600pregnant women were evaluated.Mean BMI befor pregnancy in the women with GDM was significantly higher than in the women without the above-mentioned problems(P=0.0001). The mean weight gained during pregnancy in the women with these symptoms was significantly higher than that in the women without the above –mentioned problems(P=0.039)(P=0.0001). Compared to pre-pregnancy BMI, weight gain during pregnancy had a higher with GDM(0.278 vs 0.077). Pre-pregnancy BMI in comparison with weight gain during pregnancy, had a higher correlation with GDM and macrosomia

Non-Stress Test (NST) is one of the most common methods used to evaluat fetus health, which its results are presented as reactive and non-reactive. One of the limitations of this test is the high number of false non-reactive cases. Different studies have suggested a combination of vibroacoustic stimulation and NST to reduce the number of non-reactive cases and duration of the test.

The present study examined a group of tests, and used simple randomized sampling. The number of the sample was 55 individuals and the data collection tools were NST, sonography instruments, NST result paper, a tooth brusher, a watch, a demographic questionnaire, and a checklist. Vibroacoustic stimulation with an electronic brush was performed on fetus head situated on mother’s abdomen for 3 seconds and then NST was continued for a further 20 minutes. Then the results were recorded. The obtained data were gathered by SPSS 19 software, and analyzed using descriptive statistics.

In this study, 85.5% of the non-reactive cases changed into reactive through vibroacoustic stimulation. The amount of false positive was lower with vibroacoustic stimulation in comparison with NST.

Vibroacoustic stimulation, as a technique for evaluating fetus health, makes it possible to save time, costs and personnel. It is also leads to sooner and better diagnosis of fetus health.

In epidemiological and medical studies، sometimes researchers are faced for prediction of two response variables (simultaneously) based on a number of independent variables. When the response variable is mixed، according to established limits and absence of assumption، the classical statistical methods are not enough efficient for classification and prediction goals. The purpose of this study is using Artificial Neural Network (ANN) model to predict the mixed response variable in heart disease. A total of 276 cardiac patients who were discharged from Madani Hospital were studied as historical cohort، from October 2011 to March 2012. This sample was used to predict the cholesterol and also LDL levels of patients. Data was randomly divided into two sets: training (175 cases) and testing (91 cases) sets. Data analysis was made by ANN model with SCG algorithms in MATLAB software، version 7. 11 and appropriateness of the model was assessed by the accuracy prediction. The highest accuracy of prediction of mixed response variable was 51. 76% for a four-layer ANN model. The ANN model is suggested to predict the mixed response variable in medical studies.

Backgrounds & The performance of nursing as one of the most important human sources at hospital is influenced by different factors such as corporate culture that create confidence and commitment and increase the quality of service. The aim of this survey was to study the relationship between corporate culture and organizational commitment. This is a descriptive, cross-sectional study. 150 nurses were selected by simple random method. The data were collected using 3 questionnaire which included a demographic questionnaire, Cunha and Cooper questionnaire of corporate culture with 15 questions and Allen and Mayer questionnaire of organizational commitment with 24 questions. Data was analyzed by descriptive statistics and Pearson correlation test. The mean score of the nurses corporate culture (46.7±8.1) and the mean score of the nurses organizational commitment (75.7±9.1) was relatively favorable and findings showed that corporate culture has a significant and positive relationship (P=0.00, r=0.28) with organizational commitment. Regarding the existence of the relationship between corporate culture and organizational commitment, it is recommended that authorities should plan programs to increase personnel corporate culture on important job processes.
