Introduction: A high prevalence of HCV infection among hemodialysis patients has been reported worldwide. Risk factors such as history of blood transfusion, duration of hemodialysis and recently nosocomial transmission of HCV in hemodialysis units have been identified. In this study the prevalence of Hepatitis C virus antibody and risk factors in hemodialysis patients in Markazi province is investigated. Materials and Methods: In this cross-sectional analythical study, blood samples were obtained from all 204 hemodialysis patients. Samples were tested for anti-HCV antibodies by using third generation enzyme immunoassay. The reactive samples on ELISA were confirmed by the third generation RIBA. Risk factors were evaluated by a questionnaire. Data was analysed using Chi square and logistic regression. Results: The prevalence of anti-HCV antibody among hemodialysis patients was 4.9%.Duration of hemodialysis was identified as a major risk factor in transmission of HCV (p=0.004). There was a significant relationship between anti-HCV positivity and previous renal transplantation (p=0.032). Female sex was another risk factor for HCV infection (p=0.030). There was no significant relationship between anti-HCV positivity and history of blood transfusion. Conclusion: Nosocomial transmission of HCV within hemodialysis units seems to be a route of infection in patients on hemodialysis in Markazi province. Application of dialysis precautions recommended by CDC can reduce the prevalence of HCV infection among hemodialysis patients in this province.

Background: Noticing the sensitivity of measles virus to temperature and light, maintaining its stability is highly important in live vaccines. The aim of the study is to evaluate the stability of measles vaccine produced by AIK-C strain. Materials and Methods: In this experimental study, three lyophilized vaccine vials were incubated at 37˚C for one week and their stability was evaluated via accelerated test. In addition, reconstituted vaccines were incubated at 4˚C, 25˚C, and 37˚C for 0, 4, 8, 12, 16 hours after reconstitution and their remaining infectious virus titer was measured using CCID50 method. Half-life of the reconstituted measles vaccine was evaluated according to linear regression analysis. Results: When the reconstituted vaccine was incubated at 4˚C, 25˚C, and 37˚C, the titer loss per hour was equal to 0.05, 0.1 and 0.2 Log10 CCID50, respectively. Also, the half-life of this vaccine at these temperatures was 5.31, 2.26, and 1.36 hours, respectively. Conclusion: The loss of potency for measles vaccine produced by AIK-C strain is 0.33 Log after storage at 37°C for one week, while the reported amounts for commercial vaccines such as Mevilin-L, Attenuvax, Edmonston-Zagreb, and Rimevax are 0.7, 0.7, 1 and 0.78, respectively. Lyophilized and reconstituted vaccine containing AIK-C strain is more stable in comparison with Edmonston B, Schwartz, Biken-CAM, and Leningrad strains. The stability of the reconstituted AIK-C strain vaccine is similar to Moraten strain at 37˚C.

Background: studies in adults have shown that external focus of attention is better than internal focus in motor learning. So, the aim of this study is to evaluate the effects of focus of attention- self talk on balance of women with multiple sclerosis.

Materials and Methods: In this semi- experimental study, statistical population included women with MS referred to MS Society of Arak. Whereas balance disorder in patients was diagnosed by neurologyist, they were invited to the study. Patients were accidentally divided into 3 groups each of 15 concluding control, self tak-external focus of attention and self talk- internal focus of attention groups and were evaluated by Berg balance scale. 42 samples completed executive steps of study. ANOVA and Tukey tests were used to compare balance score between groups with significant level of less than 0.05. All patients practiced balance tasks for 9 days and then they were undergone post test.

Results: Balance was improved in all groups. Although the external- self talk group was better than the two other groups, there was no significant difference between external and internal- self talk groups.

Conclusion: The findings of this study showed the effect of practice on improvement of balance skill and superiority of the experimental groups in comparison with control group. Probably, focus of attention with self talk has effect on balance of women with MS.

Background and Aim: Evaluating variability can help to investigate the process underlying motor coordination problems. The current study aimed to measure motor coordination and its variability in children with Developmental Coordination Disorder (DCD). Moreover, the symmetry of motor coordination variability in these children and the relation between motor skills and variability were explored.
Materials and Methods: After evaluating motor skills in children, aged 7-10 years using Movement Assessment Battery for Children-2 (MABC-2), 15 children with DCD and 20 non-DCD children performed a bilateral coordination task. Using motion capture system, motor coordination and variability were recorded and calculated by computing continuous relative phase and its standard deviation, respectively.
Ethical Considerations: The study with an ethical code of IR.UT.SPORT.REC.1396030 was approved by Ethics Committee of Faculty of Physical Education and Sport Sciences of University of Tehran.
Findings: Children with DCD showed significantly higher variability, while there was no significant difference between the groups in performing the coordination task. Moreover, the variability of motor coordination was found asymmetrical in children with DCD. Finally, more variability was shown to be accompanied with lower score in motor skills of the participants.
Conclusion: The current study shows the necessity of employing assessments related to underlying process of movement coordination such as variability, which can help to provide more comprehensive understanding of motor patterns of children with DCD and the strategies that they adopt to execute and produce movement.

Introduction: The fundamental role of marital satisfaction is vital in family formation and marriage survival. Marital dissatisfaction can make couples fail to solve their conflicts. Marital discontent, combined with job-related stress such as pre-hospital emergencies, can lead to heightened conflict in job responsibilities. It leads to the effect on personnel, patients, and their families. Therefore, this study aimed to investigate the marital satisfaction of pre-hospital emergency personnel at Qom University of Medical Sciences in 2023.
Methods: This cross-sectional study was conducted on 200 pre-hospital personnel of Qom University of Medical Sciences in May 2023. The sampling method was a stratified cluster. The data collection tool included the "Demographic Information" checklist and Enrich's "Marital Satisfaction" questionnaire. Data analysis was done using descriptive tests, Independent T-test, and Regression.
Results: The average age of the participants was 37.3 ± 7.06. More than half of the participants had a bachelor's degree. Most people had rotating shifts. The average score of marital satisfaction was 145.94 ± 22.21. Based on the results of the multivariate regression test, the variables of education, employment status, work experience, type of shift, having a second job, and having a job other than medical staff explain 63% of the variance of marital satisfaction of pre-hospital personnel.
Conclusions: According to the findings of the present study, in general, the marital satisfaction of pre-hospital emergency personnel of Qom University of Medical Sciences is at an average to high level. People with a fixed shift, with a second job, high work experience, without a fixed job status, and bachelor's and associate's degrees had less marital satisfaction than others. Therefore, managers and policymakers in the health field must pay more attention to the quality of family life, especially the married life of pre-hospital emergency workers with the mentioned conditions.
