Occupational strain and job satisfaction: The job demand-resource moderation-mediation model in haemodialysis units.

AIM: To examine whether job resources moderate the relationship between job demands and occupational strain, and whether occupational strain mediates the relationship between job demands and job satisfaction. BACKGROUND: The job demand-resource model suggests that job demands and job resources are related to occupational strain, and occupational strain is associated with job satisfaction. METHODS: In 2018, a cross-sectional study was conducted with a convenience sample of 85 nurses from six haemodialysis units. Linear regression with moderation-mediation analysis was conducted using SPSS software. RESULTS: Under low workload levels, no association between autonomy and occupational strain existed, but under high workload levels, a negative relationship was found between autonomy and occupational strain. Under low workload levels, a negative relationship was found between social support and occupational strain, but under high workload levels, a positive relationship was found. Finally, there was no association between occupational strain and job satisfaction. CONCLUSION: Job resources are moderators of the relationship between job demands and occupational strain. However, there was no significant association between occupational strain and job satisfaction. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse leaders should strengthen nurses' autonomy, which can reduce occupational strain. Additionally, sources of support are needed to help nurses cope with the workload and occupational strain.

Utility of first positron emission tomography-computed tomography scan as a prognostic tool following treatment of sinonasal and skull base malignancies.

BACKGROUND: The prognostic value of the first posttreatment whole body integrated positron emission tomography-computed tomography (PET/CT) scanning in patients with sinonasal/skull base malignancies is undetermined. METHODS: We retrospectively reviewed the data of all patients that underwent surgery for sinonasal/skull base malignancies in 2000-2015. The results of the pretreatment and posttreatment PET/CT findings and the clinical course were retrieved. RESULTS: Thirty-eight patients (average age 60.6 years, 20 males) were included. Sensitivity and specificity, positive predictive value, and negative predictive value of the first PET/CT scan for predicting persistent/recurrent disease were 85.7%, 87.5%, 80%, and 91.3%, respectively. Overall 5-year survival was significantly lower in the first posttreatment PET/CT-positive group (35%) compared to the PET/CT-negative group (93%) (P = .0008). CONCLUSION: Posttreatment PET/CT findings are highly prognostic in patients with sinonasal/skull base malignancies. Negative findings on the first posttreatment PET/CT scan predict a significantly better overall survival.
