Crossed pulmonary arteries is an uncommon anomaly in which the ostium of the left pulmonary artery originates superiorly and to the right of the right pulmonary artery. The pulmonary arteries then cross each other and supply their respective lungs. The recognition of this rare anomaly is important because of its association with significant cardiac and extracardiac congenital abnormalities. These congenital conotruncal malformations have long been considered part of the clinical spectrum of DiGeorge syndrome, velocardiofacial(Shprintzen) syndrome, and conotruncal face syndrome. More recent reports have shown that a high percentage of patients with these syndromes have microscopic deletions of chromosomal region 22q11. We experienced a case of crossed branch pulmonary arteries in Dandy-Walker malformation. The diagnosis of crossed branch pulmonary arteries was made by echocardiography and this case had no evidence of 22q11 deletion in high resolution chromosome study and fluorescence in situ hybridization. This case of both conotruncal malformation and Dandy-Walker malformaltion was due to an abnormal developmental process involving the neural crest. We report this case with related literature.

PURPOSE: This research aimed to investigate the effects of a cognitive rehearsal program (CRP) on workplace bullying among nurses. METHODS: A randomized controlled trial was performed. Participants were 40 nurses working in different university hospitals in B city, South Korea. The experimental group was provided with a 20-hour CRP comprising scenarios on bullying situations, standard communication, and role-playing. To evaluate effects of the CRP, we measured interpersonal relationships, workplace bullying, symptom experience, and turnover intention at preand post-intervention. Follow-up effect was measured in the experimental group only at 4 weeks after the intervention. RESULTS: After the intervention, there were significant differences in interpersonal relationships (F=6.21, p=.022) and turnover intention (F=5.55, p=.024) between experimental and wait-list groups. However, there was no significant difference in workplace bullying or symptom experience between the 2 groups. The beneficial effects on interpersonal relationships and turnover intention lasted at least up to 4 weeks after CRP. CONCLUSION: The CRP for workplace bullying improves interpersonal relationships and decreases turnover intention. So it can be utilized as one of the personal coping strategies to reduce the the turnover among nurses. Further studies on the effects of unit- or hospital-based CRP and on the long-term effects of CRP are necessary.

OBJECTIVE: Rumination is a negative coping strategy defined as repetitive and passive focusing on negative feelings such as depression. The Ruminative Response Scale (RRS) is a widely-used instrument to measure rumination, but there is continuing argument about the construct validity of the RRS, because of probable overlap between the measurement of depression and that of rumination. The RRS-Revised (RRS-R), which removed 12 items of the RRS, is suggested as a more valid instrument for measuring rumination. Therefore, we translated RRS-R into Korean and explored the reliability, validity and factor structure in patients with major depressive disorders. METHODS: Seventy-nine patients with major depressive disorder took the Korean version of RRS, RRS-R, State Trait Anxiety Inventory, Beck Depression Inventory and Penn State Worry Questionnaire. We performed exploratory factor analysis of RRS-R, and tested construct validity, internal reliability and test-retest reliability. RESULTS: The internal and test-retest reliability of RRS-R was high. Factor analysis revealed that RRS-R is composed of two factors. 'Brooding' factor explained 56.6% and 'Reflection' factor explained 12.5%. RRS-R, especially 'Brooding factor', was highly correlated with other clinical symptoms such as depression, anxiety and worry. CONCLUSION: In this study, we find out the RRS-R is more reliable and valid than the original RRS in Korean patients with depression because the RRS-R is free from the debate about the overlap of item with BDI. We also revealed that 'Brooding' is highly correlated with depressive symptoms. RRS-R may be a useful instrument to explore the implication of 'Brooding' in depression.

Objective: PD-1 inhibitors have demonstrated improved health outcomes in cancer patients. PD-1 inhibitors are well-tolerated and associated with immune-related adverse events. The objectives of this study are to analyze use patterns of PD-1 inhibitors in patients with cancer and to investigate the incidence of thyroid-related adverse reactions in patients treated with PD-1 inhibitors. Methods: The study included patients who had been administered PD-1 inhibitors (either nivolumab or pembrolizumab) at the Samsung Medical Center between October 1, 2016 and June 30, 2017. Data was collected from electronic medical records and tested using Mann-Whitney tests and Chi-Square tests for statistical significance. Associations between PD-1 inhibitors and incidence of adverse events were tested using Cox regression for age, gender, BMI, ECOG PS and medication. Results: Two hundred fifteen patients were identified as eligible for analyses. Thyroid-related adverse events occurred in 20% of patients (n=43). Thyroid function tests (TFTs) was performed in 109 patients (50.7%). Positive results of PD-L1 testing were found in 53.2% of the 94 patients who had the test. Approved doses of nivolumab (3 m/kg) and pembrolizumab (200 mg) were administered in 70.4% and 53% of patients, respectively. The analysis of risk factor of thyroid-related adverse reaction did not show statistically significant differences (Cox regression). Conclusion Thyroid-related adverse events are common in patients treated with PD-1 inhibitors and hypothyroidism is the most frequent adverse reaction. Routine TFTs monitoring is strongly recommended to evaluate thyroid function in real-world clinical practice.

BACKGROUND: Tumor-infiltrating lymphocytes, which form a part of the host immune system, affect the development and progression of cancer. This study investigated whether subsets of lymphocytes reflecting host-tumor immunologic interactions are related to the prognosis of patients with acute myeloid leukemia (AML). METHODS: Lymphocyte subsets in the peripheral blood of 88 patients who were newly diagnosed with AML were analyzed by quantitative flow cytometry. The relationships of lymphocyte subsets with AML subtypes, genetic risk, and clinical courses were analyzed. RESULTS: The percentages of T and NK cells differed between patients with acute promyelocytic leukemia (APL) and those with AML with myelodysplasia-related changes. In non-APL, a high proportion of NK cells (>16.6%) was associated with a higher rate of death before remission (P=0.0438), whereas a low proportion of NK cells (≤9.4%) was associated with higher rates of adverse genetic abnormalities (P=0.0244) and relapse (P=0.0567). A multivariate analysis showed that the lymphocyte subsets were not independent predictors of survival. CONCLUSION: Lymphocyte subsets at diagnosis differ between patients with different specific subtypes of AML. A low proportion of NK cells is associated with adverse genetic abnormalities, whereas a high proportion is related to death before remission. However, the proportion of NK cells may not show independent correlations with survival.

Ophthalmoplegic migraine (OM) is a poorly understood neurological syndrome characterized by recurrent headaches with paresis of the ocular cranial nerves. The third cranial nerve is most commonly affected; the fourth and sixth nerve less so. The etiology, pathophysiology, and definitive treatment of OM remain unclear. We here report a 12-year-old girl who presented with recurrent OM attacks. This adolescent patient demonstrated contrast-enhanced oculomotor nerves on magnetic resonance imaging during OM episodes and marked responses to steroid treatment. The findings in our present study emphasize the difficulty of OM diagnosis, even with new International Headache Society criteria, because patients rarely fulfill all of the relevant characteristics at the same time.

PURPOSE: Lithium-pilocarpine induced status epilepticus (LPSE) causes selective and age-dependent neuronal death, although the mechanism of maturation-related injury has not yet been clarified. The activating transcription factor-2 (ATF-2) protein is essential for the normal development of mammalian brain and is activated by c-Jun N-terminal kinase (JNK). It induces the expression of the c-jun gene and modulates the function of the c-Jun protein, a mediator of neuronal death and survival. Therefore, we investigated the expression of c-Jun and ATF-2 protein in the immature and adult rat hippocampus to understand their roles in LPSE-induced neuronal death. MATERIALS AND METHODS: Lithium chloride was administrated to P10 and adult rats followed by pilocarpine. Neuronal injury was assessed by silver and cresyl violet staining, performed 72 hours after status epilepticus. For evaluation of the expression of ATF-2 and c-Jun by immunohistochemical method and Western blot, animals were sacrificed at 0, 4, 24, and 72 hours after the initiation of seizure. RESULTS: Neuronal injury and expression of c-Jun were maturation-dependently increased by LPSE, whereas ATF-2 immunoreactivity decreased in the mature brain. Since both c-Jun and ATF-2 are activated by JNK, and targets and competitors in the same signal transduction cascade, we could speculate that ATF-2 may compete with c-Jun for JNK phosphorylation. CONCLUSION: The results suggested a neuroprotective role of ATF-2 in this maturation-related evolution of neuronal cell death from status epilepticus.

PURPOSE: This study was to examine the factors affecting prostate cancer screening behavior in Korean men using the health belief model (HBM). METHODS: It was a descriptive cross-sectional survey. A total of 121 participants answered questionnaires which included general characteristics, knowledge, and HBM variables related to prostate cancer and prostate cancer screening tests. RESULTS: Only 18 participants (14.9%) had had a prostate cancer screening test before. Participants who had had a prostate cancer screening test were more likely to perceive lower health status (odds ratio: 0.61 [95% confidence interval: 0.39, 0.93]), higher perceived sensitivity (odds ratio: 3.55 [95% confidence interval: 1.11, 11.36]), and higher self-efficacy (odds ratio: 5.77 [95% confidence interval: 1.51, 22.08]) than participants who had not had a test. CONCLUSION: We recommend developing an educational program which can increase the level of perceived sensitivity and self-efficacy to involve themselves in prostate cancer screening test actively.

PURPOSE: The purpose of this study was to develop a scale to measure person-centered critical care nursing and verify its reliability and validity. METHODS: A total of 38 preliminary items on person-centered critical care nursing were selected using content validity analysis of and expert opinion on 72 candidate items derived through literature review and qualitative interviews. We conducted a questionnaire survey with 477 nurses who worked in intensive care units. The collected data were analyzed using exploratory factor analysis (EFA) and confirmative factor analysis (CFA) with SPSS and AMOS 24.0 program. RESULTS: EFA was performed with principal axis factor analysis and Varimax rotation. The 15 items in 4 factors that accounted for 50.8% of the total variance were identified by deleting the items that were not meet the condition that the commonality should be .30 or more and the factor loading over .40. We named the factors as compassion, individuality, respect, and comfort, respectively. The correlation coefficient between this scale and the Caring Perception Scale was r=.57 (p < .001), which determined concurrent validity. The item-total correlation values ranged from .39 to .63, and the internal consistency for the scale was Cronbach's α=.84. CONCLUSION: The reliability and validity of the 15 item person-centered critical care nursing scale were verified. It is expected that the use of this scale would expand person-centered care in critical care nursing.
