Background: This study investigated the longitudinal associations between the degrees of positive and negative spillover in work–life balance (WLB) at baseline and reports of depressive mood at a 2-year follow-up in Korean women employees. Methods: We used a panel study design data of 1386 women employees who participated in the Korean Longitudinal Survey of Women and Families in both 2014 and 2016. Depressive mood was measured using the “10-item Center for Epidemiologic Studies Depression Scale.” Associations between the positive and negative spillover in WLB at baseline and reports of new incidence of depressive mood at 2-year follow-up were explored using a multivariate logistic regression model. Results: Negative spillover in WLB at baseline showed a significant linear association with reports of depressive mood at 2-yearfollow-up after adjusting for age, education level, marital status, number of children, and positive spillover (P = 0.014). The highest scoring group in negative spillover (fourth quartile) showed a significant higher odds ratio of 1.95 compared with the lowest scoring group (first quartile; P = 0.036). Conclusion Positive spillover in WLB showed a U-shaped association with depression. The degrees of positive and negative spillover in WLB among Korean women employees at baseline were associated with new incidence of depressive mood within 2 years. To prevent depression of female workers, more discrete and differentiated policies on how to maintain healthy WLB are required.

The 45 neonates with bronchopulmonary dysplasia among 355 neonates who were managed with mechanical ventilation and oxygen therapy in NICU of Seoul National University Chhildren's Hospital from January 1, 1968 to December 31, 1991, were analyzed for risk factors and outcome. The results were as follows: 1) The incidence of bronchopulmonary dysplasia was 12.7% 2) Respiratory Distress Syndrome was most common underlying problem. 3) The common radiologic findings of BPD were peripheral streaky density, emphysematous change, reticular or granular perihilar density, pulmonary interstitial emphysema, bubbly or small cystic change, and pneumothorax. 4) The survival rate of BPD showed 80% in the follow-up study. 5) Retinopathy of prematurity and intraventricular hemorrhage were more frequent significantly in the BPD group (p<0.05). 6) The risk factors of BPD were lower birth weight, shorter gestational age, longer duration of oxygen therapy an mechanical ventilation, and the presence of PDA.

Objective: The current study examined the differential empathic capacity, post-traumatic symptoms, and coping strategies in healthcare workers (HCWs) according to the exposure of verbal or physical workplace violence (WPV). Methods: Using online survey, a total of 422 HCWs employed at a training general hospital of South Korea participated and completed self-reporting questionnaires including the WPV questionnaire with coping strategy, the Jefferson Scale of Physician Empathy. Results: Those who experienced either only verbal violence or both physical and verbal violence had lower Jefferson Scale of Physician Empathy scores (p<0.05). Posttraumatic stress symptom severity was higher among people who experienced verbal violence than physical violence. HCWs’ exposure to verbal violence was associated with severe posttraumatic symptoms and a low level of empathy with patients (p<0.05). More than half of the victims of verbal violence responded that they did not take any action, receive organizational protection, or peer support, while most physically-abused HCWs received institutional intervention or help from others. Conclusion Our findings highlight the critical importance of reducing verbal violence, which may represent a larger psychological burden compared to physical violence, by actively implementing effective strategies and policies at the institutional level.

The purpose of this study was to determine if contrast media would enhance visualization of the endocardium for assessment of left ventricle (LV) function. In addition, differences between pre- and post-contrast evaluation for the cardiac output measurements including the modified Simpson's method and automated contour tracking (ACT) method were examined. Ten clinically healthy adult beagle dogs (three males and seven females) between 2~3 years old and weighing 6.6~10.8 kg were used. Echocardiographic examinations were performed to compare pre- and postcontrast LV endocardium visualization using a segmental scoring method. Two different methods for measuring cardiac output were also compared. LV visualization was significantly enhanced in post-contrast echocardiography (p < 0.01). Significant differences between pre- and post-contrast measurements for the modified Simpson's method (p < 0.05) were also observed. No significant difference was found for the ACT method. Contrast echocardiography provides better LV chamber opacification and significantly improves wall segment visualization. Furthermore, contrast echocardiography for measuring cardiac output is helpful for the modified Simpson's method.

OBJECTIVE: The pharmacotherapy of bipolar disorder not otherwise specified (BP-NOS) has been insufficiently studied. The aim of this prospective naturalistic study was to explore the effectiveness of lamotrigine adjunctive treatment in patients with BP-NOS. METHODS: Data from 50 patients diagnosed with BP-NOS were analyzed. On the basis of the prospective mood chart methodology, the efficacy of lamotrigine adjunctive treatment was assessed by changes in the mean Clinical Global Impressions-Bipolar Version (CGI-BP) depression scores. A paired t-test was used to test the statistical significance of the changes in CGI-BP depression scores. Repeated-measures analysis of variance (RM ANOVA) with simple effect analysis was performed to explore the sequential changes during a 52-week period. Cohen's d was calculated to measure the magnitude of the treatment effects on the changes in depression severity. Time to lamotrigine discontinuation was also calculated using the Kaplan-Meier estimates. Lamotrigine-associated adverse events were monitored every two weeks. RESULTS: A significant decrease, with a large effect size (Cohen's d=1.6), in the mean CGI-BP depression scores was associated with lamotrigine adjunctive treatment in intent-to-treat analysis (t=8.7, df=49, p<0.001). Twenty-four patients (48.0%) completed 52-week lamotrigine adjunctive treatment. Analysis of the data obtained from those completing the treatment revealed a large effect (Cohen's d=4.0) on improvement in the severity of depression (t=16.8, df=32, p<0.001). Sixty percent of patients achieved remission (n=30), and 64% of patients (n=32) showed some clinical response to lamotrigine adjunctive treatment. The mean time to lamotrigine discontinuation was 31.3+/-3.1 weeks (CI=25.2-37.4). Lamotrigine adjunctive treatment was well tolerated, with no serious rashes reported. CONCLUSION: Lamotrigine seems to be effective in the management of depressive symptoms in BP-NOS. Long-term use of lamotrigine was generally safe and well tolerated. Large-scale controlled trials might be needed to confirm the findings of this naturalistic study.
