Background: Occupational injuries and diseases are life events that significantly impact an individuals’ identity. In this study, we examined the trajectories of self-esteem among victims of occupational injury and disease and their relation to health. Methods: The Panel Study of Workers’ Compensation Insurance conducted annual followups on workers who had experienced occupational injury or disease. A total of 2,000 participants, who had completed medical care, were followed from 2013 to 2017. Growth mixture modeling was utilized to identify latent classes in the self-esteem trajectory.Additionally, logistic regressions were conducted to explore the association between trajectory membership, baseline predictors, and outcomes. Results: Three distinct trajectory classes were identified. Total 65.8% of the samples (n = 1,316) followed an increasing self-esteem trajectory, while 31.1% (n = 623) exhibited a constant trajectory, and 3.1% (n = 61) showed a decreasing trajectory. Individuals with an increasing trajectory were more likely to have a higher educational attainment (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.20–2.88), an absence of a moderate-to-severe disability rating (OR, 0.49; 95% CI, 0.25–0.96), no difficulty in daily living activities (OR, 0.81; 95% CI, 0.75–0.88), and were economically active (re-employed: OR, 2.46; 95% CI, 1.52–3.98; returned to original work: OR, 4.46; 9% CI, 2.65–7.50). Those with a decreasing self-esteem trajectory exhibited an increased risk of poor subjective health (OR, 1.89; 95% CI, 0.85–4.85 in 2013 to OR, 3.17; 95% CI, 1.04–13.81 in 2017), whereas individuals with an increasing trajectory showed a decreased risk (OR, 0.54; 95% CI, 0.43–0.68 in 2013 to OR, 0.44; 95% CI, 0.33–0.57 in 2017). Conclusion Our findings emphasize the diversity of psychological responses to occupational injury or disease. Policymakers should implement interventions to enhance the self-esteem of victims.

Background: Our study aimed to investigate the mediating role of work–family conflict (WFC) on the relationship between long commutes and workers' anxiety and insomnia. Methods: Our study measured the two dimensions of WFC, time-related, and strain-related, which were considered multiple mediators. The mediating effect of WFC on anxiety and insomnia was investigated by decomposing the total effect into a direct effect (long commuting time → anxiety or insomnia) and an indirect effect (long commuting time → WFC → anxiety or insomnia). The combined indirect effect (joint indirect effect) of strain-related WFC and time-related WFC was estimated. The effects were presented as odds ratios and 95% confidence intervals (CIs). Results: The direct effect of 120 min or longer of commuting time was 1.39 (95% CI: 1.17–1.65) times increase in the odds of anxiety and 1.64 (95% CI: 1.41–1.90) times increase in the odds of insomnia than those whose commuting time was less than 60 min. In the case of indirect effects, those whose commuting time was 120 min or longer had 1.13 times higher odds of anxiety (95% CI: 1.07–1.18) and 1.12 times higher odds of insomnia (95% CI: 1.07–1.17) via WFC. The joint indirect effects accounted for 26.4% and 18.5% of the total effect on anxiety and insomnia, respectively. The longer the commuting time, the stronger both direct and indirect effects. Conclusions Our findings highlight the mediating effect of WFC on the relationship between long commuting times and workers' anxiety and insomnia.

Methods: To operationalize precarious employment, we utilized data from the Korean Working Conditions Survey and focused on three distinct dimensions: employment insecurity, income inadequacy, and a lack of rights and protections. By constructing a summative scale ranging from -16 to 2, with lower scores indicating higher precariousness, we measured employment precariousness among Korean wage workers. To compare employment precariousness according to survey participant characteristics, we employed the Wilcoxon Rank Sum Test. Results: We analyzed a weighted number of 38,432 workers. The overall sample showed a median (Q1, Q3) summative scale score of -3 (-6, -1). The median summative score was lower for women compared to men (men: -2; women: -5; p < 0.001), as well as for young or older workers compared to middle-aged workers (young: -4; middle-aged: -2; older: -5; p < 0.001). Similarly, workers with lower educational levels (middle school or below: -8; high school: -5; college or above: -2; p < 0.001) and non-white collar workers (blue collar: -5; service/sales worker: -6; white collar: -2; p < 0.001) experienced higher levels of employment precariousness. Conclusion Our findings indicate that certain vulnerable groups, such as women, young or older adults, workers with low educational attainment, and caregiving or low-skilled elementary workers, are disproportionately exposed to high employment precariousness. Active policy interventions are needed to improve the employment quality of vulnerable groups.

Percutaneous balloon dilation with or without placement of an external biliary drain is a nonoperative alternative method for treating benign bilioenteric anastomotic strictures. Although this procedure has a high technical success rate, outcomes are less optimal when attempting to dilate refractory tight strictures. For the stricture, cutting balloon can be an option. We present four patients with benign bilioenteric anastomotic strictures refractory to conventional balloon dilation. To the patients, a peripheral cutting balloon over-the-wire system was inflated, following subsequent conventional non-compliant balloon dilation. After the balloon dilation treatment, an external drainage catheter was placed through the stricture site and maintained for up to 30 days. Technical and end-treatment success was achieved in all four patients. In conclusion, the use of cutting balloon dilation may appear to be a safe and effective alternative method of treatment in patients with benign bilioenteric anastomotic strictures refractory to conventional balloon dilation.

Purpose: To investigate adult primary open-angle glaucoma (POAG) patients’ perceived stress levels and to examine the associations with their clinical characteristics. Methods: Sixty-seven POAG patients, excluding those meeting the exclusion criteria (retinal or neurological disease diagnoses) comprised the study population. A validated questionnaire, namely Perceived Stress Scale-10 (PSS-10), was used to assess stress level. Additional data on glaucoma surgery history, medical benefit receipt, comorbidities, and daily antiglaucoma medication number were collected. The clinical characteristics of high (PSS-10 ≥15) and low stress (PSS-10 <15) patients and the risk factors associated with high stress level were subjected to a multivariable logistic regression analysis. Results: The patients were 56.8 ± 12.6 years of age on average, and 29 (43.3%) were female. The mean PSS-10 level was 13.5 ± 5.3 (range, 1–27) for the entire patient group; 31 patients (46.3%) were in the high stress group. In the high stress group relative to the low stress group, best-corrected visual acuity in the better eye was lower (p = 0.044) and the visual field defects, in both eyes, were more severe (better eye, p = 0.005; worse eye, p = 0.026). A logistic regression analysis indicated that severe visual field defect in the better eye (odds ratio, 1.159; 95% confidence interval, 1.016–1.323; p = 0.028) and lower best-corrected visual acuity in the better eye (odds ratio, 4.707; 95% confidence interval, 0.580–6.189; p = 0.072) were both likely to associated with high stress level in patients with POAG. Conclusions These findings suggest an association between severe visual function loss and higher mental stress level in POAG patients. Stress level, therefore, might be an important consideration in POAG patient management.

BACKGROUND/AIMS: Proton pump inhibitors are widely used to prevent gastric endoscopic submucosal dissection (ESD)-related bleeding, but no standard administration regimens have been established. We aimed to prospectively compare the effects of continuous infusion and intermittent dosing with pantoprazole on preventing gastric ESD-related bleeding. Additionally, we analyzed the risk factors for bleeding. METHODS: From April 2012 to May 2013, patients with a gastric epithelial neoplasm scheduled for ESD in the Pusan National University Hospital were randomly assigned to one of two groups according to the pantoprazole administration regimen (continuous infusion or intermittent dosing). The primary outcomes measured were intra- and postprocedural bleeding events. RESULTS: The final analysis included 401 patients. The rate of significant intraprocedural bleeding was 25.4% in the C group and 24.0% in the I group, with no significant difference (p=0.419). In addition, there was no significant difference in the postprocedural bleeding rate between the C and I groups (11.7% vs 10.2%, p=0.374). Multivariate analysis showed that intraprocedural bleeding was associated with the proximal tumor location, the presence of fibrosis, and the size of the resected specimen, whereas postprocedural bleeding was associated with the size of the resected specimen and the procedure/coagulation time. CONCLUSIONS: Intermittent dosing with pantoprazole is sufficient and cost-effective for the prevention of gastric ESD-related bleeding. Operators should consider tumor characteristics when planning ESD to minimize the risk of intraprocedural bleeding, and patients with large iatrogenic ulcers should be carefully monitored for postprocedural bleeding.
