Background: Assessment and control of nosocomial infections is a global priority which decreases length of hospitalization and also significantly reduces the health care costs by minimizing infections. So the present study evaluated the knowledge, self-efficacy and practice of nursing staff in Disciplines Standard Precautions to prevent nosocomial infection.Materials and Methods: This Cross-sectional and analytical study carried out on 130 nursing staff of hospitals of Arak university of medical sciences in 2013. Data collected with a valid and reliable questionnaire including of knowledge, self-efficacy and practice of nursing staff in Disciplines Standard Precautions. Data was analyzed by SPSS software using descriptive and analytical statistical methods and pearson correlation.Results: The mean score of knowledge was 46.92±14.66, practice 49.46±6.96 and average of self-efficacy was 52.2±10.81. There was not significant relationship between knowledge and Practice, but there was a significant relationship between self-efficacy, knowledge, practice and marriage (p<0.05). Moreover there was a significant relationship between knowledge and gender. (p<0.05).Conclusion: Despite moderate self-efficacy, majority of nurses did not have appropriate knowledge about prevention of nosocomial infections based on the findings of this study. Considering the important role of nurses in prevention of nosocomial infections, training is necessary to increase the prevention behaviors in nurses. Therefore, paying more attention to apply actions for training of nurses is necessary.

Background: Balance is one of the basic needs in daily activities and has an important role in static and dynamic activities. The purpose of this study is to evaluate the balance of subjects with peripheral neuropathy after 4-weeks of functional and balance exercise program.Material and methods: In this quasi-experimental study, 22 diabetic patients with diabetic peripheral neuropathy (experimental group, n=11; control group, n=11) with the mean age of 53.79 years, mean height of 163.41cm, and mean weight of 71.49 kg, were randomly selected. Berg tests used to assess the patient's balance. Twelve sessions of combined training (balance and functional training) were used as intervention. A paired t-test was used for statistical comparison between preand post-test and independent t-tests were used to compare the experimental and control groups.Results: The paired sample t-test showed that training program has significant effect on functional and dynamic balance. The comparison between the two groups showed no significant deference between pre-functional balance tests and significant post-functional balance test after training program.Conclusion: Patients with diabetic neuropathy may have an impaired functional balance. The most important factor is the damage of proprioceptive receptors and combined training (balance and functional training) may improve balance by putting extra load on the visual system, vestibular and proprioceptive stimulation system. Hence, it can be recommended as an exercise to improve balance.
