Abstract

Purpose: To evaluate workplace health education as practiced by occupational health managers based on standardized job tasks and suggest priority tasks and areas to be trained. Methods: The study was conducted between November 10, 2013 and April 30, 2014. The tool used in this study was standardized job tasks of workplace health education for occupational health managers which was developed through methodological steps. It was evaluated by 233 worksite occupational health managers. Data were analyzed using SPSS 21.0. Results: Predicting variables of workplace health education performance were the “analysis and planning” factor, type of enterprise, and form of management. Healthcare professionals and occupational health managers who managed the nonmanufacturing industry showed high importance and low performance level in “analysis and planning” factor. Conclusions: “Analysis and planning” skill is priority training area for healthcare professionals and occupational health managers who managed nonmanufacturing industry. It is necessary to develop a training curriculum for occupational health managers that include improving analysis of worksites and plans for a health education program.

Abstract

BackgroundBackground parenchymal enhancement (BPE) on dynamic contrast-enhanced (DCE)-MRI has been associated with breast cancer risk, both based on qualitative and quantitative assessments.PurposeTo investigate whether BPE of the contralateral breast on preoperative DCE-MRI is associated with therapy outcome in ER-positive, HER2-negative, node-negative invasive breast cancer.Study typeRetrospective.PopulationIn all, 289 patients with unilateral ER-positive, HER2-negative, node-negative breast cancer larger than 5 mm.Field strength/sequence3T, T1 -weighted DCE sequence.AssessmentBPE of the contralateral breast was assessed qualitatively by two dedicated radiologists and quantitatively (using region-of-interest and automatic breast segmentation).Statistical testsCox regression analysis was used to determine associations with recurrence-free survival (RFS) and distant metastasis-free survival (DFS). Interobserver variability for parenchymal enhancement was assessed using kappa statistics and intraclass correlation coefficient (ICC).ResultsThe median follow-up time was 75.8 months. Multivariate analysis showed receipt of total mastectomy (hazard ratio [HR]: 5.497) and high Ki-67 expression level (HR: 5.956) were independent factors associated with worse RFS (P

Abstract

BackgroundTo correlate parameters of Ultrasonography-guided Diffuse optical tomography (US-DOT) with pharmacokinetic features of Dynamic contrast-enhanced (DCE)-MRI and pathologic markers of breast cancer.MethodsOur institutional review board approved this retrospective study and waived the requirement for informed consent. Thirty seven breast cancer patients received US-DOT and DCE-MRI with less than two weeks in between imaging sessions. The maximal total hemoglobin concentration (THC) measured by US-DOT was correlated with DCE-MRI pharmacokinetic parameters, which included K(trans), k ep and signal enhancement ratio (SER). These imaging parameters were also correlated with the pathologic biomarkers of breast cancer.ResultsThe parameters THC and SER showed marginal positive correlation (r = 0.303, p = 0.058). Tumors with high histological grade, negative ER, and higher Ki-67 expression ≥ 20% showed statistically higher THC values compared to their counterparts (p = 0.019, 0.041, and 0.023 respectively). Triple-negative (TN) breast cancers showed statistically higher K(trans) values than non-TN cancers (p = 0.048).ConclusionTHC obtained from US-DOT and K(trans) obtained from DCE-MRI were associated with biomarkers indicative of a higher aggressiveness in breast cancer. Although US-DOT and DCE-MRI both measured the vascular properties of breast cancer, parameters from the two imaging modalities showed a weak association presumably due to their different contrast mechanisms and depth sensitivities.
