Abstract
Background and Aim: To examine the association of diet and the risk of esophageal squamous cell carcinoma (SCC) in Kurdistan province.
Materials and Methods: This was a case-control study including 47 patients with esophageal SCC and 96 healthy controls. Dietary intake was assessed using a valid semi-quantitative food frequency questionnaire. Logistic regression analysis was run to estimate odds ratios and 95% confidence intervals.
Results: The controls had a significantly higher mean body mass index (25.3 vs. 20.4) and a higher level of education than the case group, while the latter had significantly higher records of tobacco consumption and symptomatic gastresophageal reflux. An independent protective effect was observed for the highest tertile of total fruit consumption (OR: 0.13, CI: 0.04-0.45, p-value=0.001). Within the fruits group, a significant inverse association was observed for bananas, kiwis and oranges (P for trends: 0.03, 0.02 and 0.01, respectively). The effect of total vegetable intake on esophageal SCC was not significant (OR: 0.66, CI: 0.23-1.87), although a reduction in risk was observed in the highest tertile of intake. With regard to other food groups we did not find a statistically significant association.
Conclusion: The results of the present study suggest an inverse association only between fruit consumption and esophageal SCC.

Abstract
Background and Aim: The role of physical activity in prevention of non-communicable diseases is now well known. The purpose of the present study was to find any possible association between physical activity and bone mineral density (BMD) in the hip and lumbar spine areas in women in postmenopausal years.
Materials and Methods: This was a cross-sectional study including 254 postmenopausal women aged 46 to 78 years. Body composition and BMD were determined using the bioelectrical impedance analysis (BIA) and DEXA methods, respectively, and for physical activity measurement the International Physical Activity Questionnaire (IPAQ) was used.
Results: The distribution (%) of the subjects according to the level of physical activity ─ inactive, moderate and active ─ was 39.7%, 47.6% and 12.5% respectively. There was a positive association between physical activity level and lumbar spine BMD (P = 0.03) in the 55-year-old or younger women. No association was found between physical activity level and the hip BMD(P>0.05).
Conclusion: Based on the findings it may be concluded that physical activity level can be used as a predictor of bone mineral density in the lumbar spine area in women in postmenopausal years (≥55 years old).

Abstract
Background and Aim: Occupational injuries are an important human resource management challenge with negative effects on employees and organizations. A knowledge of the prevalence of occupational injuries is the first step in eliminating or reducing them. The aim of this study was to determine the prevalence of occupational injuries among financial employees of hospitals affiliated to Tehran University of Medical Sciences.
Materials and Methods: This was a cross-sectional questionnaire survey conducted in 2019 in 13 hospitals of Tehran University of Medical Sciences using a valid questionnaire to gather data. A total of 162 questionnaires were randomly distributed among the financial staff of the hospitals, but only 147 subjects completed the questionnaires. Data were analyzed using the SPSS statistical software.
Result: Analysis of the data showed that 52.6% and 50.2% of the financial staff of the hospitals were suffering from physical and mental occupational injuries, respectively. Most of the occupational physical injuries were related to headache, neck pain, back pain and visual impairment, and most of the occupational psychiatric injuries were stress and anxiety. Female and single employees experienced significantly more occupational injuries. Working in a sitting position for a long time, lack of proper equipment operation, lack of safety and health facilities, insufficient training and carelessness of staff were the causes of musculoskeletal injuries.
Conclusion: About half of the hospital financial staff were found to suffer from occupational injuries. Occupational injuries had had direct and indirect costs for the employees and the hospitals. Hospital managers should plan and implement measures to eliminate or reduce occupational injuries at an individual, group, and organizational level.

Abstract
Background and Aim: Kidney transplantation is the treatment of choice in most patients with kidney disease. It is a surgical operation in which a person’s kidney with chronic failure is replaced with a healthy kidney. The present study was conducted with the aim of estimating the survival probability of a transplanted kidney in patients with chronic kidney failure in Zahedan city, Iran.
Materials and Methods: This was a descriptive-analytical retrospective cohort study using the survival analysis method carried out in 2020. The sample size was estimated to be 211 patients.
Data were analyzed with SPSS.VER22 software using descriptive tests, the Kaplan-Meier method and the Cox proportional hazards model of survival.
Results: The data obtained showed that in general 45 (21.3%) clients had been rejected. In the multiple logistic regression model of kidney transplantation several variables, including survival time, patient survival variables, marital status, donor status, blood pressure and diabetes remained in the model (P<0.05). Further analysis of the data revealed that in the kidney disease patients with transplant survival in Zahedan city, only donor status variables, high blood pressure and diabetes remained in the final multiple Cox regression model.
Conclusion: Based on the results, it can be said that the probability of survival of kidney disease patients is independent of the type of donor and the characteristics of the recipient, which indicates the evolution of kidney transplant management over the past few years; dialysis before kidney transplantation also has an effect on the probability of survival. These factors can help to increase the probability of kidney transplant survival.
