Abstract
Background: Candida vaginitis which is mostly caused by Candida albicans is the second common cause of vaginal candidiasis in women. This study was designed to determine the clinical symptoms of Candida vaginitis and their relationship with the types of Candida species in women referring to the clinics of Shiraz University of Medical Sciences. Materials and Methods: In an analytical study, over a seven month period of sampling, through the examination of the history of 1100 patients, 450 were identified with chief complaints regarding genital infection. Samples were obtained from 280 of these patients according to their histories and the characteristics of their vaginal discharges. Of these patients, 105 were diagnosed with Candida vaginitis. The analysis of Candidal species was done through germ tube and chlamidospore agar tests. Results: Urogenital itching was severe in more than 43.8% of patients. White color genital discharges were more observable than other symptoms (88.6%). In negative Candida culture samples, severe itching, white color discharge, and disuria were reported to be 23, 80.8, and 43.5%, respectively. Candida albicans composed 70.5% of the samples. Colony count was between 51 and 500 in 49.5% of all samples. There were no significant relationships between colony count and rate of itching, family planning program, and other symptoms. Conclusion: Due to the uncertainty of diagnosis of this disease according to clinical symptoms and also, due to the consistency and resistance of Candida species, using culture method is recommended as a standard method of diagnosis.

Abstract
Background: Probiotics are live microorganisms that have positive effects on the host when consumed in sufficient amounts. According to several studies, probiotics have beneficial effects on prevention and treatment of many diseases. The aim of this study was to review animal and human studies on the role of probiotics in reducing serum cholesterol, their mechanisms of action, and a brief explanation of functional probiotic foods. Materials and Methods: This review article focused on all papers indexed in scientific databases from 2000 to 2012 using the related keywords, including cardiovascular diseases, probiotics, and serum cholesterol. Results: Probiotics are used both in dairy and non-dairy products. Nowadays, the role of many probiotic strains in health is confirmed. From the studies done in this field, it can be inferred that probiotics through several mechanisms, such as binding cholesterol to cell walls of probiotics in intestine, conversion of cholesterol into coprostanol, production of short chain fatty acids, and deconjugation of bile acids, reduce serum cholesterol. Conclusion: Certain strains of probiotics have demonstrated cholesterol-lowering properties and others are under study. Further studies are needed to identify other mechanisms involved in lowering serum cholesterol and determine their safety

Abstract
Background: Ventilator-associated pneumonia (VAP) is one of the most important causes of mortality in intubated traumatic patients admitted in ICU. The aim of current study was to determine correlation between blood products transfusion with incidence of VAP in traumatic patients under mechanical ventilation in ICU.
Materials and Methods: This study was a prospective descriptive-analytical study. Current study was carried out on traumatic patients under mechanical ventilation admitted to Imam Khomeini hospital ICU wards of Sari city, from September 2015 to September 2016. In addition to demographic data, patients' clinical information were daily recorded.
Results: Of total of 2304 patients admitted to ICU, 186 traumatic patients under mechanical ventilation longer than 48 hours were reviewed and analyzed. Among patients infected with VAP, 36 persons(87.8%) had transfusion of blood products before VAP incidence. Blood products transfusion (before and / or after 48 hours) had the highest adjusted risk ratio in the incidence of VAP (Odds ratio; OR=3.58). Also, amount of injected Packed Red Blood Cells and platelet were significantly higher in patients infected with VAP (p<0.005).
Conclusion: Considering remarkable increase in incidence of VAP following blood products transfusion and its correlation with injected PRBC and platelet, considering these modifiable risk factors for controlling and preventing the incidence of VAP in traumatic patients under mechanical ventilation in ICU is necessary and reasonable.

Abstract
Background and Aim: Lip reading is extraction of speech data from the activity of the lower part of face, particularly jaws, lips, tongue, and teeth that is a natural skill in people with hearing loss. The main purpose of lip reading is to increase the independence of people with hearing loss. Looking at the speakers facial movements significantly increase the ability to understand the spoken words, particularly in the environments where noise is present. In fact this reflects the important role of visual signals. In current study we consider the effects of education on lip reading ability by planning and instructing a lip reading program in male subjects.
Methods & Materials: Sara lip reading test 1 and 2 were used for the assessment of lip reading skills and for studying the effects of lip reading training on recognition of speech. This intervention as a semi-experimental study, was conducted on 27 male students, selected by available sampling. For data analysis, statistical analysis of variance with repeated measurements and Mcnemar was used.
Ethical Considerations: This research with the code IR.SBMU.REC.1394.144 has been approved by the ethics committee of Shahid Beheshti University of Medical Sciences.
Results: There were significant differences between Sara lip reading test 1 scores in 2 positions (P=0.000).Lip reading test scores also showed significant differences in Sara lip reading test 2 in 2 positions (P=0.000). Also between the scores of Consonant-vowel, consonant-vowel syllables, in the position before teaching lip-reading and then ,was significant difference (P<0.05).
Conclusion: The findings of this study showed that instructing lip reading has a positive effect on lip-reading ability in people.

Abstract
Background and Aim Hiding knowledge in the organization is a new topic in the field of knowledge management. The purpose of this study is to identify and prioritize the factors affecting knowledge concealment by managers in Guilan University of Medical Sciences by AHP hierarchical method.
Methods & Materials The research is applied in terms of purpose and based on a qualitative-quantitative approach. The statistical population of the study included philosophical experts in the field of management and experimental experts of the University of Medical Sciences who were selected as a sample by purposive sampling method and snowball technique until the theoretical saturation was reached. The data collection tool was a semi-structured interview. After enumerating the indicators affecting knowledge concealment and then by hierarchical analysis (AHP) method and using Expert Choice11 software, the identified factors were prioritized.
Ethical Considerations In this research, prior to interviewing the experts, written consent was received from them regarding the confidentiality of the research (Code: IR.IAU.LIAU.REC.1401.002).
Results The research findings showed that among the 7 effective factors considered by experts, the power-seeking factor has the greatest impact on knowledge concealment by managers in the University of Medical Sciences and emotional intelligence has the least weight or importance.
Conclusion Accordingly, by reducing power-seeking, in addition to creating a transparent and reliable atmosphere, it is possible to establish knowledge sharing in the University of Medical Sciences.
