Many variables affect on the sleep quality of hospitalized elderly people. This study was conducted to determine the factors disturbing sleep quality among hospitalized older adult patients in Kashan hospitals. Methods: A cross-sectional study was carried out on a sample of 390 elderly hospitalized patients in Kashan hospitals. The study data was gathered via Pittsburgh Sleep Quality Index (PSQI) Questionnaire. A global total score of 5 or greater indicated a “poor" quality of sleep. The data were analyzed using Chi square, t- test and binary logistic regression at multivariate model. Results: The total quality of sleep was poor in hospitalized elderly patients (7/2±4/8). Sex, marital status, level of education, type of ward, previous hospitalization experience, use of hypnotics at home and hospital, and previous sleep disorders were statistically associated with quality of sleep however, there was not significant relationship between quality of sleep and age, length of hospitalization, and daytime napping. In the final regression model, marital status (OR=4.6), level of education (OR=1.9), length of hospitalization (OR=1.1), Previous hospitalization experience (OR=0.4), use of hypnotics in hospital (OR=0.27) and previous sleep disorder (OR=0.01) were the most important determinants of sleep quality. Conclusion: Quality of sleep was poor in hospitalized elderly due to a wide range of sleep disturbing factors. The most important factors involved marital status, level of education, previous hospitalization experience, previous sleep disorder and use of hypnotics in hospital.

Conclution: Implementing programs of hand burn is recommended to reduce the functional problems of the hand after burning. Therefore, the nurses need to attend to education in caring of these patients. 2281 Nursing Investigating Bacterial Contamination of Nurses’ Hands in ICU regarding their Using of Jewellery Nasiriani Kh Noorishadkam M Ayatollahi J Dehghani A Zandi H 1 3 2013 20 6 709 715 27 02 2013 Introduction: Nosocomial infection is a major challenge in health care system. In fact, it is regarded as one of the risk factors in hospitalized patients which results in a significant increase in mortality,morbidity and financial burden. Noscomial infection transmission via the hands of hospital personnel to patients is known as a primary method of transmission, however, revealing such effect to the healthcare workers in order to follow the proper behavior is somehow hard .Therefore, this study aimed to investigate the microbial contamination of nurses' hands regarding jewelry. Methods: This is a descriptive analytic study. The random sampling was applied which consisted of 50 nurses working in hospitals of Shahid Sadoughi Medical University of Yazd .Samples were collected at the beginning of the shift. In fact, a culture was taken using a cotton swab soaked with sterile water on the surface of the jewelry and the area under it immediately after the withdrawal. Moreover, the samples were gleaned as many as the number of jewelries from the other Hand or an area close to the position. The samples were analyzed utilizing SPSS software version 12. Results: As the study findings indicate, most jewelries involved gold rings and gold Bracelets. Culture results were reported as 45.8% positive and 54.2% negative. Thus, there was no significant difference (p=0.33). For the below surface of jewelries, culture results were 64.6 % positive and 35.4% negative (P=0.000). Jewelry culture results for the opposite hand involved 64.6% positive and 35.4% negative (P=0.000). In general, the three comparisons showed a significant difference (P=0.000) Conclusion: The findings reveal that using jewelries increases pollution. In other words, this will increase the probabaility of nosocomial infections and pathogens transmission. Therefore, it is recommended to remove jewelry during patient care. 2282 other Investigating Nanosilver Effects on Blood Cells Counter in Male Rats Naghsh N Amirkhani-Dehkordi S Aghababa H 1 3 2013 20 6 716 723 27 02 2013 Introduction: Nanosilver particles are one of the functional grounds in nanotechnology field.

This study was designed to evaluate total goiter prevalence (TGP) and iodine/creatinine ratio among school-aged children in Urmia County. Methods: Schoolchildren (n=500) were recruited by cluster sampling from different educational areas in Urmia County. Goiter prevalence was assessed by thyroid palpation, UIE was determined by Sandell-Koltoff reaction, and Urinary creatinine was measured by the Jaffe-method. Results: In general, TGP was 12.2%. Among these, there were 48 individuals (9.6%) with grade I goiter and 13 subjects (2.6%) with grade II goiter. Mean urinary creatinine, median UIE and median I/Cr ratio were respectively 1.36±0.76 mg/dL, 14.3µg/dL, and 11.5µg/mg. Prevalence of iodine deficiency according to UIE criteria was 22.8% and that of I/Cr ratio was 41.2%. There was a correlation between age and UIE (P=001 r=0.163). UIE and urinary creatinine were correlated as well (P<0.003 r= 0.133). A correlation was also detected between I/Cr ratios and UIE (P=0.003 r=0.133) whilst a negative association was seen between age and I/Cr ratios (P=0.001 and r=–0.263). Conclusion: This investigation reconfirms that there is slight-to-mild iodine deficiency in Urmia County. The utilization of I/Cr ratio in conjugation with UIE and palpation may provide a better assessment in investigating nutritional iodine status. 2285 Nursing Assessment of Knowledge and Practice in Needle Stick Injury among Health Care Staff Rahimianfar AA Frouzannia Kh Dehghani H Khavari Z Sareban MT 1 3 2013 20 6 743 751 27 02 2013 Introduction: Needle stick injury is known as a common adverse complication that health care staff are encountered with.

The current study aimed to have quick survey on merits and demerits of implementing teleworking project in Iran's governmental organizations. Furthermore, it intends to design a model for teleworking implementation in Ministry of Health and Medical Education (MoH;ME). Methods: This is a descriptive and analytical study and its variables are also qualitative. Since in this study no occupation in MoH & ME couldnot (1000 percent) be purely teleworked, a teleworking applicant form was devised as the research to be filled by teleworking appliers. Afterwards, their teleworking applicant form was evaluated having passed from the required filters, their teleworking would be accepted or rejected. Results: According to the duty description of MoH;ME's occupations, it was clarified that the only 78 out of 250 job positions could be done by teleworking provided the required conditions as well as the reconsideration of duty descriptions were satisfied. Indeed the study results regarding the job positions of Human Resource Management Office showed that from total of 46 job positions in this office, only 22% can be done through teleworking method. Regarding teleworking appliers charactristics in MoH;ME during 2 months period, 3% of MoH & ME personnel applied teleworking and within them, 27% were male and 77% were female. Conclusion: Implementation of teleworking could increase productivity, quality of work life and decrease costs and personnel transportation bulk, however for effective implementation, first jobs should be reconsidered, then necessary technical capacity and also motivated human resources should be provided, otherwise a disorder might occur in performing the affairs. 2287 Dental Comparison of New Accuracy Degree and Tanaka Johnson Formulae for Prediction of Mesiodistal Width of Unerupted Permanent Canines and Premolars Toodeh Zaeim MH Yasaei S Tabatabaei Z Rahmani-Shahriari F 1 3 2013 20 6 770 777 27 02 2013 Introduction: It is important to predict mesiodistal crown width of the unerupted permanent canine and premolars in the mixed dentition, which helps to better determine malocclusion and its further development. Methods: In this study, 120 pair of dental study casts, belonged to subjects aged between 12-30 years, were selected and measured in the most mesiodistal width of permanent canines and premolars of both jaws, lower permanent incisors, and first upper permanent molars with the accuracy of 0/01 mm. Mesiodistal width of permanent canine and premolars in upper and lower jaws were estimated by new formula based on the permanent first upper molars and lower central incisors and then were compared with Tanaka-johnson formula. Results: The actual mean for sum of the mesiodistal width of permanent canines and premolars in the upper jaw was 21/22 mm and in the lower was 20/98 mm. The mean for sum of mesiodistal permanent canine and premolars were estimated by new formula in upper and lower jaw as 21/64 mm and 21/69 mm respectively. On the other hand, via Tanaka-Johnson formula, the predictions in upper and lower jaw were 22/41 mm and 21/92 mm respectively. Statistical analyses by means of ANOVA and Pearson correlation test revealed significant differences (P<0.001, r = 0.701). Conclusion: Sum of mesiodistal width of unerupted permanent canines and premolars teeth in the Iranian race (in Yazd) was estimated better using the new formula than applying the Tanaka Johnson formula, because of two following reasons: first, the new formula can be used at an earlier age and second, it has a higher accuracy. 2288 Exercise Physiology Catalase Enzyme Gene Expression and Oxidant Markers’ Levels in Trained Women: Effect of Incremental Exercise Tartibian B Baghaei B Baradaran B 1 3 2013 20 6 778 788 27 02 2013 Introduction: There are few studies regarding the field of catalase gene expression, antioxidant and oxidant response in trained women, thus these markers’ levels have not been designated within Iranian trained women specially in regard to incremental exercise. Therefore, this study aimed to investigate Catalase enzyme Gene expression and oxidant levels in trained women. Methods: A repeated measure design was used for this study. Fourteen trained young women in the age range of 23-25 years from urmia city were volunteered as subjects. Venous blood samples were taken in three stages, before GXT exercise test (graduate exercise test) (speed: 7/5 mile, slope grade: 6%, exercise time: 30 minutes), immediately and 3 hours after exercise. Real time PCR method was used for analysis of the mRNA of Catalase gene expression and the eutoanalyzer method was also applied for measurement of MDA activity. Results: MDA (Malondealdeide) levels increased immediately and 3 h after exercise, though it proved to be statistically significant only in recovery stage (3 h after exercise) (P<0/002). Catalase gene expression significantly increased after exercise, but this difference wasn’t significant in recovery stage (P<0/03). Also, TAS (total antioxidant status) concentration increase was significant after training exercise (P0/065). Conclusion: Incremental exercise test has increased catalase gene expression and antioxidant and free radicals levels in trained women. 2290 other The Effect of Age of Cochlear Implantation on the Improvement of the Auditory Performance in the Children Undergoing Cochlear Implantation Norouzpour H Tabatabaei HR Rajaeifard AR Hashemi B Monshizadeh L 1 3 2013 20 6 789 795 27 02 2013 Introduction: Hearing is one of the premier human senses. Being deprived from hearing is not only being unable to hear the sounds, but it is also the disability to gain a lot of helpful experiences. Cochlear implantation is introduced worldwide in order to treat the severe to profound hearing loss. Therefore, the present study aims to determine the effect of age of cochlear implantation on improvement of the auditory performance. Methods: The present follow-up study was conducted on 96 children who had referred to Fars Cochlear Implantation Center. The patients’ information was gathered from their profiles both before and after the operation. In addition, the auditory performance score was obtained in 3 stages – 6 months, 1 year, and 2 years after the implantation – through the Cap test. Also, non-parametric tests of Fridman, Willcoxon, and Mann-Withney U were utilized in order to analyze the data of the study. Results: The mean of the children’s auditory performance 6 months, 1 year, and 2 years after the implantation was measured as 2.8+1.03, 4.36+1.04, and 5.34+1.02, respectively. Besides, the median of their auditory performance 6 months, 1 year, and 2 years after the implantation was calculated as 3, 5, and 5, respectively. Also, a statistically significant relationship was observed between the independent variable of age of cochlear implantation and the auditory performance score 6 months, 1 year, and 2 years after the implantation. Conclusion: In line with other studies conducted on the issue, the present study showed the improvement of the auditory performance in the children who benefited from cochlear implantation. Moreover, the results of the present study revealed that the age of cochlear implantation can be of great help in determining the candidates of cochlear implantation. In other words, it can be a major prognostic factor of the response to the treatment 2291 Cardiovascular Investigating the Prevalence of Renal Artery Stenosis Following Coronary Artery Angiography and Related Risks in Hypertensive Patients Candidate for Coronary Artery Angiography in Yazd Afshar Hospital Nough H Riazi AR Najarzadegan MR 1 3 2013 20 6 796 804 27 02 2013 Introduction: Renal artery stenosis is the most prevalent disease of renal artery and has an important role in making hypertension and renal atrophy. Since in previous researches, despite high frequency of risk of cardiovascular disease in Iran, there did not exist any general research investigating risk factors of coronary artery disease and incidence of contemporary renal artery stenisis, this study intended to investigate these factors in hypertensive patients in Iran. Methods: This cross-sectional study was performed on 264 patients who were hypertension candidate for coronary artery angiography in Afshar hospital in Yazd. At the time of coronary angiography, patients had renal angiography at the same time. Among those patients, those who had coronary artery disease were selected and thus prevalence and severity of renal artery stenosis and its relationship with cardiovascular risks were investigated. The gathered data were analyzed by Spss-18 software. Results: Prevalence of renal artery stenosis (equal and over 50%) was 38.25 in all patients in other words, in men and women it was 43.56% and 56.44% (P=0.04) respectively. Prevalence of co-morbidity of coronary artery disease and renal artery stenosis with 1 vessel disease was 34%, 2 vessel disease was 57.14% and 3 vessel disease was 54.17% with significant differences (P>0.01) Conclusion: According to high prevalence of renal artery stenosis in hypertensive patients and high prevalency with simultaneous hypertension and coronary artery disease, renal angiography after coronary angiography may assist for unknown renal artery stenosis and better treatment. 2295 Dental Correlation between Self Efficacy, Type D Personality and Health Locus of Control with Control of Blood Sugar in Patients with Diabetes Type II Afkhami Ardekani M Zare H Alipor A Poursharifi H Arab Sheibani Kh 1 3 2013 20 6 805 813 03 03 2013 Introduction: Glycemic control in type 2 diabetic patients seems to be affected by personality as well as psychological factors. Therefore, this study intends to investigate the relationship between self efficacy, type D personality and health locus of control with control of blood sugar in patients with diabetes type 2. Methods: All women with diabetes in Yazd Diabetes Research Centre were considered among which 80 were selected by random sampling. They completed Shirer’s self-efficacy scale questionnaire, type D personality questionnaire and Multiple health locus of control questionnaire. Then they were introduced to the lab for blood test. Data was analysed by SPSS software and stepwise regression method. Results: The results of Pearson correlation coefficients showed that self efficacy (r = 0/83) and type D personality (r=0/55) and health locus of control with HbA1c correlated positively and significantly (p <0/05). Stepwise regression analysis showed that R2=0/73 In other words, 73% changes of the variable HbA1is determined by self-efficacy, type D personality and health locus of internal control variables Conclusion: Impact of personality and psychological variables in diabetes glycemic control is important. So we can implement interventions to increase the efficacy of internal control sites and modify the features of type D personality in patients with diabetes and thus to improve glycemic control and adherence to treatment regimens in these patients. 2297 Pathology First Report of Three Cases of a Rare Blood Group Oh “Bombay Phenotype” in a Family in Yazd, Iran Javadzadeh Shahshahani H 1 3 2013 20 6 814 819 03 03 2013 The Bombay (Oh) Phenotype is a rare blood group.
