Background:  Occupational factors, working conditions, age, gender, exercise, acquired habits, and stress affect a person's sleep quality. The aim of this study was to investigate sleep quality, work stress, and related factors among office workers in a hospital., Methods:  This cross-sectional study was conducted with office workers actively working in a hospital. A questionnaire consisting of a sociodemographic data form, the Pittsburgh Sleep Quality Index (PSQI), and Swedish Workload-Control-Support Scale were used to assess the participants.    Results: The mean of PSQI score was 4.32±2.40 and 27.2% of the participants had poor sleep quality. In the multivariate backward stepwise logistic regression analysis, it was found that shift workers were 1.73 times (95% CI: 1.02-2.91) more likely to have poor sleep quality, and a one-unit increase in work stress score increased the risk of having poor sleep quality by 2.59 times (95% CI: 1.37-4.87). An increase in age was found to decrease the risk of poor sleep quality in workers (OR =0.95; 95% CI: 0.93-0.98)., Conclusion:  This study suggests that reducing workload and increasing work control as well as enhancing social support will be effective in preventing sleep disturbances. It is important, however, in terms of providing guidance for hospital employees in planning future measures to improve working conditions.

Background: Dysbaric osteonecrosis (DON) is defined as avascular bone necrosis, usually involving specific parts of the long bones, which is seen in divers or compressed-air workers due to exposure to pressure. We describe a case of DON in an artisanal diving fisherman working underwater for many years. Methods: A 48-year-old male case was admitted to the occupational disease outpatient with left shoulder and arm pain for 1-2 years. Since the age of 20, he has been artisanal diving fishing with a hookah at a depth of 20-25 meters in the sea. In 2011, he received hyperbaric oxygen therapy for widespread pain in the whole body due to decompression sickness (DCS). In the case's left shoulder joint x-ray and magnetic resonance imaging, degenerative changes in the acromioclavicular joint and signal changes consistent with osteonecrosis starting from the subcortical area of the humeral head and extending to the proximal shaft of the humerus were observed. Conclusions: DON is among the most common long-term pathologies in professional divers. In Turkey, as in our case, not applying safe decompression procedures and unsafe diving practices are common among diving fishers. In studies, the frequency of exposure to pressure, duration and depth of dive, insufficient decompression, formation of DCS and increasing age were associated with DON. Today, DON remains an occupational hazard with significant medical and social consequences. Diving fishers should be informed about the sequelae of DCS and trained on the safety measures to be taken.

Background: Taxi drivers have an increased risk of low back pain due to both physical and occupational conditions. This study aims to determine the prevalence of low back pain and occupational risk factors among taxi drivers working in İzmir, Turkey., Methods: This study was conducted with 447 taxi drivers at randomly selected taxi stands between April and September 2021. The questionnaire included demographic, individual, and work-related questions; the Nordic Musculoskeletal Questionnaire; and the Back Pain Functional Scale (BPFS)., Results: The prevalence of low back pain in the last year was 49.7%. In multivariate logistic regression analyses, the risk factors for low back pain included having a body mass index of 25-29.9 kg/m2 (OR= 1.67, 95% CI 1.01-2.76) or ≥30 kg/m2 (OR= 2.15, %95 CI 1.19-3.87), no physical activity (OR= 1.66, 95% CI 1.06-2.62), years of work >10 (OR= 3.23, 95% CI 1.89-5.53), no weekly rest period (OR= 3.11, 95% CI 1.42-6.81), having no lumbar support on the driver's seat (OR:1.67, 95% CI:1.05-2.66), or undecisive job satisfaction (OR= 2.07, 95% CI 1.17-3.66). Being undecided about job satisfaction (OR= 2.34, 95% CI 1.15-4.92) and not having physical activity (OR= 2.10 CI 1.08-4.08) were found to be risk factors for reduced BPFS scores., Conclusion: A strong correlation was found between the frequency of low back pain and the BPFS score and occupational factors. Early detection and management of low back pain are critical to avoid increased low back pain and related injuries among taxi drivers.
