Abstract
Background & Objectives: This study aimed to determine of the seroprevalence of visceral leishmaniasis to design a prevention and control program in Bojnoord district.
Methods: This was a descriptive and cross sectional study with multistage random sampling method. The study was carried out on children up to 12 years old and 10% of adult’s population in 8 rural areas of Bojnoord district in 2007. In total, 1608 blood samples were collected to detect anti-Leishmania antibodies. All the samples were tested by direct agglutination test (DAT). In order to determine Leishmania species, necropsy was performed on four suspected dogs in the studied areas. The species of Leishmania was determined by RAPD-PCR and PCR-RFLP methods using to amplify the ribosomal internal transcribed spacer 1 (ITS1).
Results: Thirty and eight (2.36%) out of 1608 collected blood samples had anti-Leishmania antibodies at titer 1:800 and nine (0.56%) were just positive at 1:3200 by DAT. There was no statistically significant difference between female and male seroprevalence (p<0/05). The seoprevalence in children <=12 years old compared to individuals greater than 12 years old did not show any statistically significant (p<0/05). Amastigotes were observed in all 4 necropsied dogs. The species of Leishmania isolated from 2 dogs, was determined as L.Infantum. Their ITS1 sequences were registered with Accession numbers EU810776 and EU810777 in NCBI.
Conclusions: These findings showed that visceral leishmaniasis has been circulated with low endemicity in Bojnoord district. Therefore an appropriate monitoring system is needed for health services in this area.

Abstract
Background & Objectives: To be able to measure the extent of job stress, it is essential to use a standardized tool based on a standard theoretical model. The study aims to test the psychometric properties and criterion validity of the Farsi version of the Effort Reward Imbalance (F-ERI) questionnaire.
Methods: The Farsi version of the ERI Questionnaire was distributed to 227 male employees in Isfahan Polyacryle Company. Internal consistency, reliability, discriminative validity, and factorial structure were evaluated.
The relationship between scales and depression was measured assessed by using logistic regression to criterion validity. Data were analysed by SPSS 18 and LIZREL 8.5.
Results: Mean score of effort, reward, and overcommitment were 10.7, 41.4, and 14.2 respectively Cronbach’s alpha coefficients were 0.61, 0.85 and 0.67 and split-half coefficients were 0.53, 0.85, and 0.65. All of item-total correlations were more than 0.20 correlation between each item and its scale were more than 0.4 except for one item. Effort and overcommitement had a good fit for construct validity.
Conclusion: Current study results indicated the Farsiversion of the Effort Reward Imbalance (F-ERI) questionnaire is a reliable and valid tool to measure psychosocial stress at work among Farsi-speaking employees. It is advisable to evaluate the tool in longitudinal studies and other industries which included female employees. We refer the investigators to see the longitudinal results of current project which is under publication.

Abstract
Background and Objectives: Since there is inconsistency reports in relationship between shift work (SW) and blood pressure (BP), therefore we aimed to show any association between SW and BP by using of Bayesian Multilevel Modeling, which is a reliable method for this type of analysis.
Methods: The profiles of 4145 workers in Polydactyl Iran Corporation were examined in historical cohort between 1996 until 2008. All relevant analysis was performed by Win Bugs software.
Results: Approximately 98 percent of study population was male. Of total 1886 (45.5%), 307(7.4%), 1952 (47.1%) of participation were day worker, two rotation shift worker and three rotation shift worker respectively. After controlling confounding factors, there was no significant relationship with Systolic BP (P=0.911) and Diastolic BP (P=0.278).
Conclusion: In general, the results of our historical cohort study do not support a relationship between SW and BP. We suggest multi center and prospective cohort studies with controlling more confounding factors in this area.
