Hospital's traditional charter that mostly emphasized productivity has been replaced by a charter that stresses social and environmental issues. On this basis, to achieve success, managers should regard both the inner and the outer environments of hospitals. This study aims at measuring hospital's social responsibility. The present descriptive-analytic study was carried out through a cross-sectional method in 2010. The study population consisted of hospital managers of the city of Isfahan (n=21). The data collection instrument was a researcher-made questionnaire. The instrument's content validity was determined by the expert's views and its reliability calculated through Cronbach's α was found to be 0.95. The collected data were analyzed using SPSS software (version 16) and the hypotheses were tested by t-test, ANOVA and Eta coefficients. The maximum mean score was 100. The mean score of hospital's social responsibility was computed to be 68.6. The mean scores of leadership and inner processes, market place, community policies, environmental policies, and workplace policies were found to be 72.2, 70, 67.8, 67.4 and 66.2, respectively. There was no significant relationship between hospital's social responsibility and type of hospital's possession and activity (pvalue > 0.05). The social responsibility of hospitals was assessed as moderate. To improve hospital's social responsibility, it is suggested that more attention be paid to workplace and environmental policie.

One of the most important reasons why organizations are distinguished from one another is the degree of application and implementation of information technology in their organizational activities. In this regard, individual factors contribute considerably to the application of information technology (IT). Such factors include employee's perceptions and attitudes towards information technology and their demographic characteristics which affect the level of information technology acceptance and implementation.

In this cross-sectional study, 110 middle managers from teaching hospitals of Tehran University of Medical Sciences (TUMS) were chosen. A structured questionnaire was used as the data collection device and its validity and reliability were confirmed by a pilot study.

Of the participants, 62.9% were males and 37.1% were females. The findings show that there is a statistically significant relationship between perception and making decisions based on the implementation of information technology. However, there was no significant relationship between work experience, education and training on the one hand and IT implementation on the other.

The results show that human factors (perception and decision) have a considerable impact on the implementation of information technology. Top managers and experts should consider the important aspects of human factors and also the factors affecting them.

Excessive Bleeding continues to play a key role and an important cause of morbidity and mortality after cardiopulmonary bypass (CPB). The goal of this study was to determine the differences in bleeding and transfusion between OPCAB and on -pump CABG patients. In a randomized, double blinded prospective study 300 patient's undergoing coronary revascularization surgery were enrolled, 150 CABG patients were compared with 150 OPCAB patients. The patients were assessed during the first 72 hours to determine the postoperative side effects. The 2 groups were compared using the chi-square test or fisher's exact test and the rank sum test. CABG patients received more intraoperative red blood cells (P<0.0001), more albumin and more fresh- frozen plasma (P<0.0001). Postoperatively, CABG patients were more likely to receive more platelets (29.3% ν 70.7 %, P<0.007). During the operative and the initial 4-hour postoperative period OPCAB patients exhibited greater blood loss (P<0.0001); however, at 12,24and 72 hours postoperatively, CABG patients exhibited greater blood loss. There were4 death in CABG patients (P<0.05) Despite not reversing the heparin at the end of the OPCAB surgery, OPCAB surgery was associated with an overall reduction in platelets, fresh- frozen plasma, Albumin and transfusion requirements.

Malnutrition is one of the causative agents of death in children. So, this study was done for assessment of anthropometric indices of students and malnutrition status in Golpayegan, Iran. This research was done as a descriptive - analytical (inferential) study. Sampling was done as clusters and multistage. In order to collect data, the standard questionnaire of anthropometric indicators standards (ANIS) pattern was used. Low and low height was used based on Z score. Collected data was analyzed by Epi-info and SPSS software. Of 1062 schoolboys, 550 were male and 512 were female. Anthropometric indicators including age (month), weight (kg) and height (Cm) showed significant differences (P < 0.05). The mean of malnutrition index was 5.4 % (WAZ<-2) and 3% (WAZ<-2) in our study. The significant difference between prevalence of slimness, low weighting and low growth in rural and urban Schoolboys is an indicator of the undesirable situation in rural areas. Therefore, nutritional planning should be considered in rural children.

Elderly is a physiological phenomenon with many inevitable complications, which their effects significantly can be reduced by individual's life style. Therefore in this study we have evaluated the impact of subject's knowledge on their lifestyle. This study was a semi experimental and interventional one that has been conducted in Urmia University of Medical Science. Thus 200 women between 54 to 80 years old were enrolled in this study and their knowledge, attitude and behavior toward a healthy lifestyle was surveyed before and 6 months after giving them a proper education. Subsequently the required information gathered from questionnaires and the data analyzed by mcmanaman paired and t paired tests. In this study all data analyzed by SPSS software and the P value lessu than 0.05 recognized to be statistically significant. The scores of before and 6 months after subjects get the required education were 29.165.86 vs. 34.266.32 respectively (P<0.001). This significant difference demonstrates the positive impact of life style education on attitude, behavior and knowledge of individuals in respect to their lifestyle. These results were even more magnificent comparing the literate and illiterate subjects. Based on our study we conclude that education has an important positive role in all elder groups improving their lifestyle.

Adverse events in hospitals are found to be a major problem of all health systems in the world. In fact, drug interaction side effects are now the fourth leading cause of death in the U.S. The aim of the current study was to identify the opinions of clinicians working in Shariati and Emam hospitals towards the use of computer applications for detecting drug-food interactions. Ninety clinicians including physicians, pharmacists and nurses were selected randomly in the current descriptive- analytical study. The opinions of clinicians toward using computer application systems for detecting drug-food interactions were assessed by a questionnaire. The questionnaire's validity and repeatability was examined in a pilot study. Cronbach's alpha was 0.85 which indicated an acceptable level of repeatability of the questionnaire. The questionnaire was distributed among the academic staffs in order to determine its validity. 95.4% of clinicians had positive attitudes towards the requirement of computer application to detect drug-food interactions. Around 94% of them showed their willingness towards using the computer application systems. Therefore, use of computer application seems to be necessary in health system. The collection and analysis of data encourages further investments in computerized system to prevent drug-food interaction. Such built-in warning systems in hospitals alert doctors to drug-food interaction and improvement in patient care. Screening each patient's medication plan for drug-food interactions can reduce medical error and improve the quality of health care.

Bone sialoprotein (BSP) is a specific marker of osteoblastic differentiation. In this research, the effect of Zoledronic Acid on BSP expression and methylation status during osteoblastic differentiation of mesenchymal stem cells (MSCs) was evaluated. In this experimental study, MSCs were isolated from human bone marrow. For osteogenic differentiation, hMSCs were pulse treated with zoledronic acid, and were incubated in osteogenic differentiation medium for 3 weeks. The DNA and RNA were extracted after the first, second and third weeks of culture and also from undifferentiated MSCs. After Sodium bisulfate (SBS) treatment, gene specific methylation analysis for BSP was carried out using Methylation Specific PCR technique. BSP expression was observed in osteoblastic differentiated cells whereas it was not seen in MSCs. MSP showed that BSP was unmethylated during osteoblastic differentiation. BSP was expressed from the first week of differentiation. This confirms that zoledronic acid accelerates osteoblastic differentiation. Unmethylation status of BSP indicates that zoledronic acid does not have any effect on BSP methylation status. Other genetic or epigenetic mechanisms may control BSP expression during osteoblastic differentiation induction by zoledronic acid.

Theses are considered as one of the sources for research in the field of education. The aim of this study was to determine the popular topics during 1349-1389 (1970-2010) and to examine the amount of educational interference and the type of such interference in different theses.

This research study was done using the descriptive-analytic method and employing the content analysis technique. The choice of topics was based on the categories derived from the Medical Headings of the American National Library. All related theses (336 in this field) were reviewed and the data were analyzed by SPSS software.

In this review, most finished theses belonged to Tehran University of Medical Sciences (62.5%), Tarbiat Modares University (25.3%), and Iran University of Medical Sciences (12.2%). MSc theses were mainly about diseases (23.8%); however, doctoral dissertations were mostly about the prevention of diseases(26.2%).

Although in the recent decade, there has been an increase in new topics and educational interference in theses, some important issues like the training of patients are still neglected. It seems that some strategies like preparing a suitable information bank of thesis in the field of health education can be a good guide for selecting new topics and ignoring old ones.
