PURPOSE: The aim of this study is to explore levels of suicidal ideation and identify subgroups of high suicidal risk among the depressed elderly in Korea. METHODS: A descriptive cross-sectional design was adopted on secondary data from the 6th (1st year) Korean national health and nutrition examination survey (KNHANES). A total of 239 depressed elders aged 60 or over who participated in the KNHANES. The prevalence of suicidal ideation and its related factors, including sociodemographic, physical, psychological characteristics and quality of life (EQ-5D index) were examined. Descriptive statistics and a decision tree analysis were performed using the SPSS/WIN 23.0 and SPSS Modeler 14.2 programs. RESULTS: Of the depressed elderly, 28.9% had suicidal ideation. Three groups with high suicidal ideation were identified. Predictive factors included perceived stress level, household income level, quality of life and restriction of activity. In the highest risk group were those depressed elderly with moderate and low levels of stress, less than .71 of EQ-5D index and restriction of activity, and 80.0% of these participants had suicidal ideation. The accuracy of the model was 80.8%, its sensitivity 85.9%, and its specificity 68.1%. CONCLUSION: Multi-dimensional intervention should be designed to decrease suicide among the depressed elderly, particularly focusing on subgroups with high risk factors. This research is expected to contribute itself to the policy design and solution building in the future as it suggests policy implications in preventing the suicide of the depressed elderly.

PURPOSE: The purpose of the study was to identify to identify the nursing needs and stress levels among spouses of women hospitalized with preterm labor, and to determine factors influencing spousal stress.METHODS: Data were collected from 95 spouses of hospitalized pregnant women due to preterm labor at a hospital in Gyeonggi province from June to December of 2016. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression.RESULTS: The mean score of spouses' nursing needs was 3.06±0.42 and stress was 1.85±0.44 out of 4.00. The highest score of nursing needs was 3.37±0.51 in assurance and the highest score for stress was 2.26±0.72 for patient's illness and prognosis. There was a significant positive correlation between stress in spouse and nursing needs (p=.004). Stress was explained by nursing needs (β=.28) and hospitalization days (β=.21).CONCLUSIONS: The results of this study suggest that appropriate nursing interventions are required to address the nursing needs at the beginning of hospitalization and to reduce the stress among spouses of hospitalized pregnant women diagnosed with preterm labor.

PURPOSE: This study aimed to test the mediating effect of uncertainty appraisal and coping style in the relation between uncertainty and anxiety in hospitalized pregnant women diagnosed with preterm labor. METHODS: The participants were 105 pregnant women diagnosed with preterm labor in hospitals in Korea. Data were collected from July to October 2017. The measurements included the Uncertainty in Illness Scale, Uncertainty Appraisal Scale, Coping Style Scale, and State Anxiety Inventory. Data were analyzed using descriptive statistics, an independent t-test, correlation, and multiple regression following the Baron and Kenny method and Sobel test for mediation. RESULTS: The mean score for anxiety was 2.29 out of 4.00 points and for uncertainty it was 2.46 out of 5.00 points. There were significant correlations among uncertainty, uncertainty danger appraisal, uncertainty opportunity appraisal, problem-focused coping, emotion-focused coping, and anxiety. Uncertainty danger appraisal (β=.64, p < .001) had a complete mediating effect in the relation between uncertainty and anxiety (Z=4.54, p < .001). Uncertainty opportunity appraisal (β=−.45, p < .001) had a complete mediating effect in the relation between uncertainty and anxiety (Z=3.28, p < .001). Emotion-focused coping (β=−.23, p=.021) had a partial mediating effect in the relation between uncertainty and anxiety (Z=2.02, p=.044). CONCLUSION: Nursing intervention programs focusing on managing uncertainty appraisal and improving emotion-focused coping are highly recommended to decrease anxiety in hospitalized pregnant women diagnosed with preterm labor.

Purpose: The purpose of this study was to identify the predictors influencing fear of falling in community-dwelling elderly women with mild cognitive impairment (MCI). Methods: A secondary data analysis was performed using data of 65 years or older elderly women with MCI participating in the 7th Korea Longitudinal Study of Ageing of the Korea Employment Information Service. The study subjects included 368 elderly women with MCI. For data analysis, descriptive statistics and logistic regression with complex samples were performed using IBM SPSS ver. 23.0. Results: 89.9% of the elderly women with MCI had fear of falling. There were significant factors such as religion (OR=8.85, 95% CI: 3.39~23.15), restriction of activity (OR=6.84, 95% CI: 2.14~21.90), depression (OR=0.75, 95% CI: 0.62~0.90), and MMSE (OR=1.30, 95% CI: 1.03~1.63), predicting fear of falling in community-dwelling elderly women with MCI. Conclusion Differentiated strategies should be developed for elderly women with MCI to decrease fear of falling and prevent falls with understanding of contributing factors. This study will provide fundamental information on programming and a policy proposal related to fear of falling for elderly women with MCI.

Purpose: Specialty choice in residency training has a significant impact on an individual’s career and satisfaction, as well as the supply-demand imbalance in the healthcare system. The current study aimed to investigate the quality of life (QOL), stress, self-confidence, and job satisfaction of residents, and to explore factors associated with such variables, including postgraduate year, sex, and especially specialty, through a cross-sectional survey. Methods: An online survey was administered to residents at 2 affiliated teaching hospitals. The survey had a total of 46 items encompassing overall residency life such as workload, QOL, stress, confidence, relationship, harassment, and satisfaction. Related survey items were then reconstructed into 4 key categories through exploratory factor analysis for comparison according to group classification. Results: The weekly work hours of residents in vital and other specialties were similar, but residents in vital specialties had significantly more on-call days per month. Residents in vital specialties had significantly lower scores for QOL and satisfaction. Specifically, vital-surgical residents had significantly lower QOL scores and higher stress scores than the other specialty groups. Satisfaction scores were also lowest among vital-surgical residents, with a marginal difference from vital-medical, and a significant difference from other-surgical residents. Female residents had significantly lower satisfaction scores than their male counterparts. Conclusion Residents in vital specialties, particularly vital-surgical specialties, experience significantly worse working conditions across multiple dimensions. It is necessary to improve not only the quantity but also the quality of the system in terms of resource allocation and prioritization.

PURPOSE: Appropriate animal models of atherosclerotic plaque are crucial to investigating the pathophysiology of atherosclerosis, as well as for the evaluation of the efficacy and safety of vascular devices. We aimed to develop a novel animal model that would be suitable for the study of advanced atherosclerotic lesions in vivo. MATERIALS AND METHODS: Atherosclerotic plaque was induced in 24 iliac arteries from 12 rabbits by combining a high cholesterol diet, endothelial denudation, and injection into the vessel wall with either saline (n=5), olive oil (n=6), or inflammatory proteins [n=13, high-mobility group protein B1 (HMGB1) n=8 and tumor necrosis factor (TNF)-α n=5] using a Cricket™ Micro-infusion catheter. Optical coherence tomography (OCT) was performed to detect plaque characteristics after 4 weeks, and all tissues were harvested for histological evaluation. RESULTS: Advanced plaque was more frequently observed in the group injected with inflammatory proteins. Macrophage infiltration was present to a higher degree in the HMGB1 and TNF-α groups, compared to the oil or saline group (82.1±5.1% and 94.6±2.2% compared to 49.6±14.0% and 46.5±9.6%, p-value<0.001), using RAM11 antibody staining. On OCT, lipid rich plaques were more frequently detected in the inflammatory protein group [saline group: 2/5 (40%), oil group: 3/5 (50%), HMGB1 group: 6/8 (75%), and TNF-α group: 5/5 (100%)]. CONCLUSION: These data indicate that this rabbit model of atherosclerotic lesion formation via direct injection of pro-inflammatory proteins into the vessel wall is useful for in vivo studies investigating atherosclerosis.

BACKGROUND: Woman kidney donors face obstetric complication risks after kidney donation, such as gestational hypertension and preeclampsia. Studies on childbirth-related complications among Asian women donors are scarce. METHODS: This retrospective cohort study included woman donors aged 45 years or younger at the time of kidney donation in a single tertiary hospital between 1985 and 2014. Pregnancy associated complications were investigated using medical records and telephone questionnaires for 426 pregnancies among 225 donors. Matched non-donor controls were selected by propensity score and the maternal and fetal outcomes were compared with those of donors. Primary outcomes were differences in maternal complications, and secondary outcomes were fetal outcomes in pregnancies of the donor and control groups. RESULTS: A total of 56 cases had post-donation pregnancies. The post-donation pregnancies group was younger at the time of donation and older at the time of delivery than the pre-donation pregnancies group, and there were no differences in primary outcomes between the groups except the proportion receiving cesarean section. Comparison of the complication risk between post-donation pregnancies and non-donor matched controls showed no significant differences in gestational hypertension, preeclampsia, or composite outcomes after propensity score matching including age at delivery, era at pregnancy, systolic blood pressure, body weight, and estimated glomerular filtration ratio (odds ratio, 0.63; 95% confidence interval, 0.19–2.14; P = 0.724). CONCLUSION: This study revealed that maternal and fetal outcomes between woman kidney donors and non-donor matched controls were comparable. Studies with general population pregnancy controls are warranted to compare pregnancy outcomes for donors.

Three-dimensional (3D) printing technology, with additive manufacturing, can aid in the production of various kinds of patient-specific medical devices and implants in medical fields, which cannot be covered by mass production systems for producing conventional devices/implants. The simulator-based medical image demonstrates the anatomical structure of the disease, which can be used for education, diagnosis, preparation of treatment plan and preoperative surgical guide, etc. The surgical guide is used as a patient-specific medical device for guiding incision, resection, insertion, and marking. As 3D printers can output materials that can be inserted into the human body, the patient-specific implant device that reflects the patient's anatomy and surgical plan could be of relevance. In addition, patient-specific aids, including gibs, splints, prostheses, and epitheses, could be used for a better outcome. Finally, bio-printing is also used to cultivate cells to produce functional artificial tissues.
