Abstract
Background: One of the major causes of increasing nosocomial infections is
misusing disinfectants and antiseptics in hospitals. The aim of this study was to
evaluate the efficacy of disinfectants and antiseptics using in injections and dressing
wards, operation rooms and kitchen of Hamedan hospitals.
Materials and Methods: In this study 742 samples were collected before and after
disinfections from different parts of injection, dressing wards and operation rooms.
Disinfectants and antiseptics that were used in different parts of wards were
Halamide, Beh-Assa, Kereoeline, Formaldehyde, Glutaraldehyde, Chlorhexidine,
Hygiene, Savlone, Alcohol 70% and UV ray. The efficacy of disinfectants that were
prepared in hospitals and medical microbiology laboratory of medicine faculty was
evaluated. The efficacy of disinfectants and antiseptics were tested on Staphylococcus
and E. coli by disk diffusion method. Data was gathered through a questionnaire and
analyzed using K2 and Mann-Whitney methods.
Findings: From 742 samples, 308 positive cultures (41.6%) were detected. The
frequency mean of the contamination before disinfection was 50.1% and after
disinfection was 33.8%. From 308 positive cultures in two hospitals, 173 (56.2%)
gram negative bacteria and 135 (43.8%) gram positive bacteria were isolated. The
most effective disinfectants that were used in two hospitals were Glutaraldehyde 2%,
Formaldehyde 8%, Chlorhexidine 1%, Savlone 3.2%. The lowest effective
disinfectants were Beh-Assa 1%, Kereoeline 2.5%, and Alcohol 70%. The frequency
mean of contamination before UV ray disinfection was 51.4% and after disinfection
was 48.6%, which indicate no significant difference. Disinfectants and antiseptics that
were prepared in hospitals and those that prepared in medical microbiology laboratory
showed minor differences.
Conclusion: In this study, the frequency mean of contamination before and after
disinfections showed significant differences (P-value=0/001). So, the efficacy of
disinfectants used in the two hospitals was satisfactory. However, disinfectants that
were prepared in hospitals and those that prepared in medical microbiology laboratory
showed minor differences. Therefore, it is suggested that the disinfectants and
antiseptics which are used in hospitals should be prepared under supervision of
hospital health experts.

Falah M1, Kavand A2, Yousefi Mashouf R3 1. Professor, Department of Parasitology, Faculty of Medicine, Hamadan University of Medical Sciences, Hamadan, Iran 2. MSc in Parasitology, Boroujerd Social Security Organization, Boroujerd, Iran 3. Associate Professor, Department of Microbiology, Faculty of Medicine, Hamadan University of Medical Sciences, Hamadan, Iran Abstract Background: Hydatid cyst, the larval stage or metacestode of Echinococcosis, is an infection caused by cestode species of the genus Echinococcus and often localized in viscera of animals and humans. Hydatid cyst is typically filled with a clear fluid (hydatid fluid) that is sterile bacteriologically. Bacterial infection of hydatid fluid is sometimes present, but not always, and this leads to sterilizing the cyst and prevents producing protoscoleces. In this study the bacterial infection rate of animals hydatid cyst in Hamadan and Boroujerd slaughterhouses were compared. Materials and methods: Referring to Hamadan and Boroujerd slaughterhouses a total of 5709 livestock were inspected for the presence of hydatid cysts. In infected livestock, cyst number, size (diameter), type, and fertility or infertility on the basis of protoscolex presence, and bacterial infection status were determined and recorded. The hydatid fluid of all the collected cysts was cultured separately for isolation and identification of bacterium. Results: Hydatid cysts were found in 6.5% of the animals in Hamadan and in 7% of the animals in Boroujerd. In Hamadan slaughterhouse, only 20% of cysts were fertile and the rest were infertile however, in Boroujerd slaughterhouse, 32% of the cysts were fertile. The isolated bacteria in infected cysts in Hamadan were as bellow: Escherichia coli, Klebsiella, Proteus, Enterobacter, Staphylococci β-hemolytic and non hemolytic, Pseudomonas and Edwardsiella. The most common bacteria in Hamadan were E. coli (23.94%) and Klebsiella (22.5%), and in Boroujerd E. coli (35.7%) and Klebsiella (42.8%). In Boroujerd the rates were 93% and 7% respectively. Conclusion: This study indicated that the infection rate of hydatid cysts was not statistically significant in the two regions of Hamadan and Boroujerd. A high percentage of cysts in both regions were infected bacteriologically.

Abstract
Background : Some studies have shown that the serum concentration of 25- hydroxy vitamin D which is represent the status of body vitamin D, has a diverse relationship with obesity status, and the risk of obesity decreases in people with high level of 25- hydroxy vitamin D. The aim of this study is to investigate the correlation between the serum level of 25- hydroxy vitamin D and anthropometric indices, glucose, lipid profile, serum insulin, and insulin resistance in obese women.
Materials and Methods: This study was carried out on 43 obese women and 43 healthy women with normal weight as a control group, aged 20-50. They were matched for age and physical activity. For each participant, a 3-day 24-hours food recall was filled. Moreover, fasting blood sampling was taken to measure blood levels of fasting blood glucose, 25- hydroxy vitamin D, lipid profile and serum insulin.
Results: The mean level of serum 25- hydroxy vitamin D, insulin and also insulin resistance based on IR-HOMA index in the group of obesity and control were 28.05 ± 16.66 versus 25.72 ± 14.08 (P=0.48 ) , 25.97 ± 7.53 versus 25.93 ± 9.32 (P=0.98 ) , and 6.39 ± 2.6 versus 5.83 ± 2.5 (P=0.30) respectively. Between the anthropometric indices, 25- hydroxy vitamin D had a significant relationship only with body weight in obese group (p=0.033, r= 0.326 ). No significant relationship was observed between serum 25- hydroxy vitamin D with blood sugar, lipid profile, serum insulin level and HOMA-IR in obese women.
Conclusion: No significant relationship was seen between serum level of 25- hydroxy vitamin D with anthropometric indices (except for body weight), serum levels of glucose, lipid profile and insulin resistance in the obese women.

Abstract
Background: Cognitive insight is a complex and multidimentional concept. The clinical measurements of insight have focused primarily on patients’ unawareness of their having a mental disorder and of their need for treatment. Modern approaches have focused on some of the cognitive processes involved in patients’re-evaluation of their anomalous experiences and of their specific misinterpretations. The aim of this study was the examination of factor structure of the Beck Cognitive Insight Scale (BCIS) in a nonclinical iranian sample.
Materials and Methods: For this purpose, 476 university students, completed the Beck Cognitive Insight Scale (BCIS). The data were analyzed by LISREL and SPSS softwares.
Results: The results showed that 2 main factors: Self-reflectiveness and Self-certainty which had been revealed primarily by Beck and his colleagues (2004) have been obtained as independent subscales in this research too.
Conclusion: The results provided tentative support for the factor structure of the BCIS, and suggest that the BCIS is a valid measure to use in a non-clinical population.

Abstract
Background: The aim of this study was to compare Brain-Behavioral Systems in patient with multiple sclerocis (MS) and normal individuals.
Materials and Methods: This research was a post facto comparative study, subjects included healthy persons and all patients with MS, which in summer and autumn 2013 referred to neurologists in the Lorestan province. Of the population using as samples, 117 cases (75 patients and 42 normal subjects) were selected, then Gray- Wilson Personality Questionnaire was completed for them. To analyze the data, multivariate analysis of variance (MANOVA) test was used to compare the two groups.
Results: The results showed, in BAS scales, people with MS had significantly lower scores than normal subjects
Conclusion: What comes from findings indicates that a low score in behavioral activation as a pathological factors in chronic diseases such as MS is concerned and is in need of psychological treatment.

Abstract
Background : This study was done with the aim of investigating the role of cognitive and emotional deficiencies in anticipation of membership in addicted and non-addicted groups.
Materials and Methods: This fundamental and reviewing type research is a cross-sectional comparative study that was performed retrospectively. Population of the study was all the male substance abusers referred to addiction treatment centers in one of the cities of Lorestan province in 2014. The selected population included 100 of substance abusers and 100 normal people (from the patients, accompanies) selected by purposive sampling method. All participants completed cognitive failures questionnaire (CFQ) and alexithymia questionnaire (TSA-20). The point analysis was applied to analyze the data. Analysis was performed using SPSS-20.
Results: In point analysis at simultaneous method, seven predicting variables (difficulty in describing and identifying feelings, thoughts turned to the outside, memory problems, distractibility, oversight and not reminding the names) and in the stepwise method, three predicting variables (cognitive failures, difficulty in describing feelings and memory problems) for the only function of the point is explained by the difference between two groups of addicted and non-addicted.
Conclusion: The results showed that addicts and non-addicts can be distinguished from cognitive and emotional impairment.

Abstract
Background: Latent autoimmune diabetes of adults (LADA) is a slowly progressive form of diabetes managed with diet and oral hypoglycemic agents before becoming insulin requiring. Islet autoantibodies are used for differential diagnosis between LADA and Type 2 diabetes mellitus. The aims of this study were to investigate the frequency of LADA using islet autontibodies in population with T2DM and characterize clinical and biochemical characteristics of them.
Materials and methods: In this cross-sectional study, 86 T2DM patients aged between 28-67 years were tested for the presence of autoantibodies by ELISA technique. The Glutamic acid decarboxylase antibody, Islet Cell Antibody and Insulinoma Antigen2 Antibody were evaluated for diagnosis of LADA patients.
Results: Of 86 T2DM, 35 (40.70%) were antibody positive and 51 (59.30%) persons were negative for any antibody. A significant difference was found between groups in age at study, insulin therapy, C- peptide levels and family history of autoimmune diseases. On the other hand, no significant difference was found between the two groups in other risk factors.
Conclusions: Among our T2DM subjects, the number of LADA patients were not high. Also, multiple autoantibodies were more frequent than single autoantibodies in LADA patients

Abstract
Background: Studies have shown that Sirtuins have critical roles in the regulation of inflammation and oxidative stress, while hTERT has a protective effect via increasing the length of telomers in cardiovascular disease. The aim of this study was to assess the effects of omega 3 and vitamin E supplementation on the gene expressions of SIRT1 and hTERT and serum hsCRP level in CAD patients.
Materials and Methods: Participants in this Randomized Clinical Trial consisted of 60 non-smoking male CAD patients, with age ranges 45- 65 years, who were categorized into three groups, receiving: 4g/day of omega 3 and vitamin E placebo (OP); omega 3 (4g/day) and vitamin E 400IU/day (OE); and omega 3 and vitamin E placebos (PP) for two months.
Results: Gene expression of SIRT1 increased significantly in the OE group (P = 0.039), but gene expression of hTERT was not significantly different between the study groups. Supplementation with omega 3 and also co-administration of these fatty acids with vitamin E significantly decreased hsCRP level in OP and OE groups (P=0.008 and P= 0.050, respectively).
Conclusion: Supplementation with omega 3 and vitamin E seems to include beneficial effects on CAD patients, possibly via increasing gene expression of SIRT1, and also by lowering inflammation through decreasing serum level of hsCRP in these patients.
