Background: Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a newly identified coronavirus. Our knowledge about survival rate and prognostic factors of the disease is not established well. This study proposed to estimate the survival function of COVID-19 in western Iran.Methods: This retrospective cohort study was performed in Hamadan province, western Iran. The study included patients that referred to the provincial hospitals during 7 months period from February 20 to September 20, 2020. The follow up of each subject was calculated from the date of onset of respiratory symptoms to the date of death. Demographic and clinical data were extracted from patients’ medical records. Kaplan-Meier method, log-rank test, and Cox regression were used for the analysis of the data. Results: The overall 1, 5, 10, 20, 30 and 49-day survival rate were 99.57%, 95.61%, 91.15%, 87.34%, 86.91%, and 86.74% respectively. A significant association was observed between survival time with age, gender, history of traveling to contaminated areas, co-morbidity, malignancies, and chronic diseases, and hospital units.Conclusion: Educational programs and access to healthcare could be implemented as modifiable factors to reduce the mortality rate and burden of this disease in COVID-19 patients.

Background: Traumatic spinal cord injury (TSCI) can cause numerous adverse effects on the spinal cord and neural tissues. These injuries may have negative effects on physical and psychological health during the lifespan. Objectives: The present study aimed to investigate the epidemiology of TSCI in patients with trauma admitted to Bessat Hospital of Hamadan between 2007 and 2017. Methods: A cross-sectional study was conducted on 3,219 patients with traumatic spinal injuries admitted to Bessat Hospital of Hamadan between 2007 and 2017. Data were collected from the hospital information system. Data analysis was performed using SPSS. Quantitative data were expressed as mean, standard deviation, and frequency, and qualitative data were analyzed using the chi-square and Fisher's exact tests. The significance level was considered to be less than 0.05. Results: Mortality was significantly associated with gender (P = 0.001), age (P = 0.051), external causes of injury (P = 0.001), and type of injury (P = 0.001). The length of hospital stay was significantly associated with the type of injury (P = 0.001) and external causes of injury (P = 0.001), whereas there was no significant relationship between the length of hospital stay and gender, age, and surgery (P > 0.05). Conclusions: Mortality rates were highest at the age of 55 years or over among other age groups. Thus, effective interventions and programs should be implemented for this age group.

Mothers of cesarean section need more support for breastfeeding. The purpose of this study was to use Bristol's tool for lactation counseling on the breastfeeding status in mothers undergone Cesarean section. Methods: In this quasi-experimental study,80 primiparous women after cesarean section In Fatemieh Hospital of Hamedan in year 2018 were selected by available sampling method and assigned to two groups of test (pairs) and control (individual days) (40 persons per group). In two groups, the researcher reviewed the Bristol Breastfeeding checklist, assessed the breastfeeding status, nuchal infant, milk swallowing and infant suction and, based on the need, a breastfeeding counselor was provided in the test group. The counseling was given to the mother during the first 2 hours, 2 days, 10 days and one month after delivery. During this time, the control group received routine care only. The lactation continuity questionnaire was completed for both groups during the four months after delivery. Results: Two groups had no significant differences in demographic variables (P > 0.05). There was a significant difference between the mean duration of lactation during the four months postpartum (P <0.001). The mean of Bristol instrument scores in the first session did not have a significant difference between the two groups, but in the second, third and fourth sessions after delivery, there was a significant difference between the two groups (P <0.001). Conclusion: The Bristol tool is a good tool for evaluating mothers breastfeeding.

Background and Objective: Considering the importance and high prevalence of musculoskeletal disorders, this study aimed to investigate the role of mental workload, fatigue, and sleep quality in the development of musculoskeletal disorders. Materials and Methods: This study included 243 employees working at Borujerd health center. The participants were selected based on simple random sampling. The data were collected using the Cornell Musculoskeletal Disorders Questionnaire, Sophie Fatigue Questionnaire, and Pittsburgh Sleep Quality Questionnaire. Moreover, the Subjective Workload Assessment Technique was utilized to evaluate the mental workload. The data were analyzed using SPSS software (Version 18) through the Pearson correlation coefficient, the Chi-square test, and regression analysis. Results: According to the results of this study, back pain was ranked as the most prevalent disorder. The results of the correlation analysis showed a significant association between mental workload and fatigue with musculoskeletal disorders (P≤0.02). Moreover, a significant relationship was observed between sleep quality and musculoskeletal disorders (P≤0.02). Conclusion: It can be concluded that reduced workload and fatigue, as well as improved sleep quality, can decrease the risk of musculoskeletal disorders among the staff.
