RESUMO
OBJECTIVE: The purpose of this study was to assess the intensive care unit nurses' knowledge of evidence-based guidelines for ventilator-associated pneumonia (VAP) prevention at Guilan University of Medical Sciences (GUMS) hospitals, Guilan Province, northern Iran. METHODS: This cross-sectional study included 219 nurses working in 14 intensive care units at 11 Guilan hospitals. The questionnaire consisted of three parts of demographic information, nurses' knowledge of evidence-based guidelines for the prevention of VAP, and the barrier for the implementation of these guidelines. RESULTS: Of the 219 nurses, 171 (response rate 78.1%) participated in this study, and their mean knowledge score was 4.6. There was no significant relation between nurses' knowledge score and their work experience (P = 0.327), education degree (P = 0.189), and their position (P = 0.168). CONCLUSION: The level of knowledge regarding VAP prevention seems inadequate in this study. Although having knowledge about the principles of evidence-based care cannot guarantee the implementation of these principles, lack of knowledge may be a potential barrier to adherence to evidence-based guidelines for the prevention of VAP.

PURPOSE: The purpose of this study was to achieve more retention and stability and to delay or prevent screw loosening. MATERIALS AND METHODS: Twenty implants (Implantium 3.4 mm, Dentium, Seoul, Korea) were divided into 2 groups (n = 20). In the first group, an adhesive material was applied around the screw of the abutments (test group). In the second group, the screws are soaked in saliva (control group). All the screws were torqued under 30 N/cm, Then, the samples were gone through a cyclic fatigue loading process. After cyclic loading, we detorqued screws and calculated detorque value. RESULTS: In comparison with the control group, all the implant screws in the test group were smeared with the adhesive material, showing significant higher detorque value. CONCLUSION: There are significantly higher detorque values in the group with adhesive. It is recommended to make biocompatible adhesive to reduce screw loosening.
