Abstract
Abstract:
Background and aim: Nursing staff are always at risk of work-related musculoskeletal disorders which is the most important health problems among nurses. This study aimed to assess the prevalence of musculoskeletal disorders in nursing personnel.
Methods: This cross-sectional study was conducted in 2014. In this study, 200 nurses in teaching hospitals in Shiraz were selected by random cluster sampling. The Nordic questionnaire was used for data collection. The data was analyzed using t tests and chi-square tests.
Results: Results showed that 100 percent of the study population in the last 12 months, at least one organ of the body's involved in musculoskeletal disorders. Most problems were related to the back (12.7), knees (12.6) and lower back (12.4). Significant relationship was observed between sex and the prevalence of musculoskeletal disorders of the neck. Moreover, a significant association was seen between age and prevalence of musculoskeletal disorders in the leg.
Conclusions: Nurses have a high prevalence of musculoskeletal disorders and risk factors associated with the job is complex.

Abstract
Background & aim: Intense sports activity, by creating oxidative stress, plays a role in causing some muscle damage and the spread of inflammation after the activity. On the other hand, it has been stated that oxidative stress tolerance can be done by stress proteins such as hemoxygenase. Therefore, the aim of the present study was to determine and investigate the effect of intense endurance training on hemoxygenase-1 and TNF-α enzyme levels in the stomach and intestinal tissues of male Wistar rats.
Methods: In the present experimental study conducted in 2017, 16 male Wistar rats aged 8 weeks were randomly divided into 2 groups (control and intense endurance training) after 10 familiarization sessions and weight lifting (mean and the standard deviation of the control group was 203.125 ± 8.18 and intense endurance training was 211.25 ± 7.9). The intense endurance training protocol included running on a treadmill for 8 weeks (5 sessions per week), water and standard food were freely provided to the samples. 48 hours after the last training session and 4-hour fasting, the mice were dissected and tissue samples were collected, and hemoxygenase-1 enzyme concentration and TNF-α level were measured using an ELISA kit. Collected data were analyzed using independent t-test.
Results: The results indicated that intense endurance training had no significant effect on the level of hemoxygenase enzyme in the stomach tissue of rats (p=0.88). Moreover, the amount of hemoxygenase-1 enzyme in the intestinal tissue of mice did not change significantly (p=0.79). The amount of TNF-α in the stomach tissue of mice was not meaningfully different between the two groups (p=0.48). The amount of TNF-α in the intestinal tissue of the two groups was not significantly different (p=0.12).
Conclusion: Due to the non-change of TNF-α level, probably regular endurance sports training made the stomach and intestinal tissues safe from the destructive effects of intense endurance training by creating a beneficial adaptation in the antioxidant system. On the other hand, there is a possibility that the lack of significant changes in the inflammatory index in the present study could be related to the intensity of the exercise used. Correspondingly, if the intensity of sports activity is suitable for changes in inflammatory index levels, the lack of proper exercise by the samples of the present study was probably a factor in the absence of significant changes.
