Abstract
Background and Objectives: Noise-induced hearing loss is a prevalent work-related morbidity in the country. We determined the strength of association between hearing loss and occupational noise exposure as the first step in prevention programs.
Material and Methods: A historical cohort study involving 100 exposed and 31 non-exposed subjects was conducted. Noise exposure was estimated using sound level meter BSEN 60651, Type 2. Past noise exposure was estimated using the existing data on the place and type of work. Audiometry was used to assess hearing loss in each subject in 3- year intervals on an occupational cohort from 1993-2004.
Results: Noise-induced hearing loss was found in 49% (49 subjects) of the exposed group and 9.7 %( 3 subjects) of non-exposed group (p<.0001). Nobody used any form of hearing protection routinely in either group. Relative risk for noise-induced hearing loss was 5.1(CI95%: 1.7- 15.1).Time at risk was estimated 24.9 years (22.7-27.1) in exposed and 22.2 years (20.7-23.7) in unexposed group by survival analysis.
Conclusion: More legislation, hearing conservation programs, and surveillance and biological monitoring of work sites and workers are required to prevent occupational hearing loss. Planning strategies for noise assessment and control can help improve the work environment. Gross occupational exposure to noise has been demonstrated to cause hearing loss and the authors believe that occupational hearing loss in the country is a widespread problem.

Abstract
Background & Objectives: To determine the prevalence of HBV infection in the Golestan Province (southeastern part of the Caspian littoral, Iran).
Methods: A single cluster study was conducted in 2005, based on a sample of households, representative of the population aged 25-65 years in Golestan. All participants were invited for face-to-face interviews to gather demographic data. Blood samples were drawn and analyzed for serum markers of HBV infection such as HBsAg and HBcAb by the ELISA method. Factors associated with hepatitis B seroprevalence were analyzed using SPSS13 and STATA /8.
Results: A total of 1850 subjects were screened. The age- & sex-standardized prevalence for HBsAg positivity was 9.7% (95%CI=0.07-0.11). Rates were higher in males than in females (10.8% vs. 8.6%) (OR=1.28 95% CI=0.9-1.7). HBV seroprevalence in unmarried individuals was significantly higher than in those who were married (OR=2.13 95%CI=1.29-3.5). HBsAg(+) status was more frequent in urban areas (OR=1.46 95% CI=0.9-2.3). Thirty-six percent of population was HBcAb positive. HBcAb(+) prevalence was significantly higher in females (OR=1.46 95% CI=1.19-1.8) and married people (OR=1.58 95%CI=1.02-2.45), and also in urban areas (OR=1.34 95% CI=1.09-1.6).
Conclusions: This study shows that the prevalence of HBsAg(+) status in the Iranian province of Golestan is at a level regarded as "high" by the World Health Organization. It is higher than reported by pervious studies in Iran so it is important- especially for health providers and policy makers- to recognize risk factors and design appropriate prevention programs.

Abstract
Background and Objectives: Making an accurate clinical diagnosis can be a great challenge with pediatricians. We aimed to compare the initial diagnosis and final diagnosis for hospitalized children in one teaching hospital in Iran.
Methods: In this cross-sectional study, patients’ clinical files were used. The relationship between variables was assessed by ANOVA and X2 statistical tests. The agreement rate between final and primary diagnosis was evaluated by Kappa coefficient.
Results: A total of 1310 patients’ hospital files were reviewed. There were 1244 (94.9%) cases with complete agreement, 12 (0.9%) with relatively agreement and 54 (4.2%) cases without agreement. The overall Kappa coefficient for primary and final diagnosis was 0.88.
Conclusions: The agreement rate between primary and secondary diagnosis in this teaching hospital was high. This might be due to academic atmosphere in teaching children hospital

Abstract
Background & Objectives: The epidemic of HIV has been become worldwide. Infected people with HIV which are
most intravenous drug users (IDUs) and/or people who have unsafe sex are important source of transmission of
infection to other persons in a community. Since there is little known about the knowledge and attitudes of HIV
positives about HIV in Iran, therefore we decided to measure the level of knowledge and attitudes of this group
in Golestan province in compare with individuals with risky behavior.
Methods: This cross-sectional study was conducted on 54 HIV+ persons and 134 people with high risk behavior
individuals in 2007 year.
Results: Our study showed that HIV- (High risk group) cases had higher education level (P=0.034). Rate of
jobless was higher in HIV+ persons (P<0.001). HIV+ cases had lower income (P=0.037). Both groups had
moderate knowledge and poor attitude on HIV/AIDS. Level of attitude in HIV+ positive persons was lower than
high risk group (P=0.05).
Conclusion: It is concluded that these susceptible persons and also infected individuals with HIV regardless of
their socio-economic levels need more continuous education in structured programs.

Abstract
Background and Objectives : Various studies have reported different survival rates of patients with gastric cancer in Iran, and there is no overall estimate of the survival rate. The aim of this study was to conduct a meta-analysis of one, three, and five-year survival rate of patients with gastric cancer in Iran.
Methods: In this study, all of the national databases including Iran Medex, Magiran, SID, and Medlib and the English databases including Google Scholar and PubMed were searched by using the keywords “stomach cancer”, “survival rate” and other Persian and English synonymous keywords, in the period 1392-1339 . Then, all articles with inclusion criteria and acceptable quality were investigated. Der Simonian and Laird random effects models were used to combine the results of all studies. Other analyses including subgroup analysis, sensitivity analysis, and assessment of publication bias were performed by using the funnel plot, and Beg’s and Egger’s tests. Finally, the data was analyzed using STATA software.
Results: Of the 235 articles found in the initial search, nine studies were eligible for this study. According to these studies, one, three and five-years survival rate of patients with gastric cancer was 0.57 (95% CI: 0.45-0.70), 0.29 (95% CI: 0.22-0.37), 0.17 (95% CI: 0.13-0.21), respectively.
Conclusion : Researches conducted in different parts of Iran are limited and there are no exact statistics on the survival rate in other parts of Iran. Therefore, further studies in the whole country are required to obtain more precise estimates of the survival and factors affecting it.

Abstract
Background and Objectives: The study aimed to analysis the psychometric properties of the health system resilience scale, assessing it and to introduce a conceptual model for qualitative analysis of Iran health system in the face of the civid-19 crisis.
Methods: In this Mixed-method study, the determination of face and content validity was performed using 8 experts. The structure validity was investigated in a cross-sectional study through an electronic survey of 178 actors in the Iran health system. Resilience has been assessed in five dimensions using 5point Likert scale.
Results: The percentage mean score of the Iranian health system resilience in the face of the Covid19 crisis was 41/08 and in the moderate level. The percentage mean score (standard deviation) for 5 dimension include awareness 39/2 (21), diversity 38/7 (21), self-regulation 36 (20/6), integration 39/9 (21/5) and adaptation 41/2 (21/8). Confirmatory factor analysis indicated the appropriate fit of the information with the five-component structure.
Conclusion: The maximum score of resilience dimension belongs to adaptation and the lowest to the self-regulation indicating that it requires interventions to involve the private sector, and to design a new delivery system for crisis situations. The questionnaire can be used as a standard instrument for assessing the health system resilience.
