PURPOSE: The study was undertaken to identify factors affecting perception of the importance and practice of patient safety management (PSM) among hospital employees in Korea. METHODS: This study was conducted using a descriptive design and a self-report questionnaire. Two hundred and eighty employees were recruited from three hospitals using a convenience sampling method. Measures were perception of the importance, practice, and characteristics of PSM. Data were analyzed using descriptive statistics including t test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression. RESULTS: Factors affecting perception of the importance of PSM were whether hospital employees were in contact with patients while on duty, weekly working hours, education on PSM, and perceived adequacy of PSM system construction. Factors affecting the practice of PSM were perceived adequacy of work load, perceived adequacy of PSM system construction and perception of its importance. CONCLUSION: The findings of this study indicate a need for developing strategies to improve perception of the importance and practice of PSM among all hospital employees, and provide a reference for future experimental studies.

Purpose: Interpersonal competence, a key competence for patient-centered care by nurses, should be understood. Therefore, factors influencing the interpersonal competence of nursing students should be identified to explore and enhance their interpersonal relationships during the undergraduate educational curriculum for nursing educators. In this study factors influencing interpersonal competence, especially on self-assertiveness and empathy in nursing students were identified and analysed. Methods: A cross-sectional study design was used for the study in two Korean nursing colleges with similar baccalaureate nursing curricula. A total of 251 nursing students from freshman to senior year completed a questionnaire to measure related factors that were assumed to influence nursing students’ interpersonal competence. Data were collected from October 11~31, 2016. Study variables included self-assertiveness, empathy, interpersonal competence, and socio-demographic status. Multiple regression analysis was used for data analysis. Results: Nursing students’ interpersonal competence was explained by personality (β=.22), self-assertiveness (β=.16) and empathy (β=.38). The explanatory power of these predictors was 26.8% (p<.001). Conclusions Nursing students’ interpersonal competence during the undergraduate nursing years can be enhanced by educational strategies that improve their interpersonal relationship as patient-centered care providers. Simultaneously, the attitude of the nurse educator is also important for nursing students who are to be treated as valuable learners and to improve students' empathy and self-assertiveness ability.

PURPOSE: The purpose of this study was to evaluate the effects of a devised posture management program based on the Theory of Planned Behavior in adolescents with mild idiopathic scoliosis. METHODS: A quasi-experimental study was conducted. It involved a nonequivalent comparison group design with pretest and posttest. Forty-four female adolescents with mild idiopathic scoliosis participated; data from 35 participants (20 for the test group, 15 for the control group) were used for the final analyses. The devised posture management program ran for 6 weeks. Posture management behavioral determinants (attitude, subjective norms, perceived behavioral control, and behavioral intention) as cognitive outcomes and muscular strength and flexibility as physical outcomes were measured three times: at baseline, week 6 and week 8. Cobb's angle as another physical outcome was measured twice: at baseline and week 8. Descriptive analysis, repeated measures analysis of variance and t test were used for data analyses. RESULTS: Attitude, perceived control, and behavioral intention were consistently enhanced by the posture management program. The intervention increased flexibility and muscular strength and decreased Cobb's angle, which reduced spinal curvature. Frequency of posture management exercise showed a gradual increase in the test group. CONCLUSION: The results indicate that the posture management program is effective in maintaining posture management behavior in adolescents with mild idiopathic scoliosis for both cognitive and physical outcomes. The posture management program should be helpful in expanding the role of school nurses in improving the health status of adolescents with mild idiopathic scoliosis.

OBJECTIVE: To evaluate characteristics of cognitive impairments according to the location of aneurysmal subarachnoid hemorrhage (SAH) using a computerized neuropsychological test (CNT). METHOD: A total of 211 patients were transferred to our rehabilitation department after becoming neurologically stable following aneurysmal SAH. Twenty four of the 211 patients met the inclusion criteria and participated in a screening test using the mini-mental state examination (MMSE). Twenty patients with a MMSE score <26 were followed prospectively with a CNT and Beck depression inventory (BDI). Eleven patients had anterior communicating artery (ACoA) aneurysms and the other 9 had middle cerebral, internal carotid or posterior communicating artery aneurysms. RESULTS: There were no differences in age, education, Hunt and Hess grade, or Fisher grade between the patients with ACoA aneurysmal SAH compared to patients with other aneurysmal SAH. In patients with ACoA aneurysmal SAH, scores of BDI (p=0.020), verbal learning test were lower than those of other aneurysmal SAH patients. In contrast, patients with non-ACoA aneurysmal SAH took significantly more time in auditory (p=0.025) and visual continuous performance tests (p=0.028). The cognitive deficit following aneurysmal SAH could be characterized by its location using CNT. CONCLUSION: Using CNT in aneurysmal SAH patients could be a useful tool for evaluating the characteristics of cognitive impairment and planning rehabilitation programs according to each characteristic.

Antinuclear antibody (ANA) testing is used to diagnose systemic autoimmune rheumatic disease (SARD). Nuclear homogeneous patterns on ANA-HEp-2 cells can result from anti-double-stranded DNA (dsDNA), anti-nucleosome, anti-histone, anti-Scl-70, or anti-dense fine speckles 70 (DFS70) antibodies (Abs). This study aimed to find a way to discriminate DFS70 Abs from others by way of assessing neutrophil nuclear staining on anti-neutrophil cytoplasmic antibody (ANCA) testing. Nuclear staining on ANCAneutrophils was assessed to stratify nuclear homogeneous patterns on ANA-HEp-2 cells. Enrolled subjects included (1) young individuals with a dense fine speckled pattern on ANA testing (young non-SARD group, n=71) and patients with (2) systemic lupus erythematosus (SLE group, n=35); (3) rheumatoid arthritis possibly with histone, nucleosome Abs, and others (RA group, n=51); and (4) diffuse systemic sclerosis with Scl-70 Abs (diffuse SSc group, n=19). Negative rates (95% confidence interval) of neutrophil nuclear staining were 97.2% (90.2%-99.7%) in the young non-SARD group, 2.9% (0.1%-14.9%) in the SLE group, 3.9% (0.5%-13.5%) in the RA group, and 47.4% (24.5%-71.1%) in the diffuse SSc group. The negative rate of the young non-SARD group was significantly higher than those of the other groups (all p<0.05). In conclusion, this study suggests that the assessment of nuclear staining on ANCA-neutrophils can help to stratify nuclear homogeneous patterns on ANA-HEp-2 cells and thus to determine whether the ANA pattern is attributed to DFS70 Abs, which can be found in healthy individuals, especially in young individuals.

OBJECTIVES: The purpose of this study was to evaluate the effect of nutrition education using materials based on social cognitive theory. Education topics focused on improving health-related and dietary self-awareness and behavior capability in adolescents. METHODS: Participants were recruited from a middle school for girls; 67 students (educated group, n=34 and control group, n=33) participated. The education group received 12 lessons in club activity class. Self-administered surveys were conducted for each group before and after the nutrition education program. The questionnaires consisted of variables such as self-efficacy, outcome expectation, outcome expectancy, knowledge, and dietary practices based on the social cognitive theory. Education satisfaction was evaluated using a five-point Likert scale for two sections: a) teaching and learning and b) education results. The data were analyzed using a t-test and Chi Square-test (significance level: p < 0.05). RESULTS: In the education group, post-education, there were significant differences in self-efficacy (p < 0.05), knowledge (p < 0.01), and dietary practices (p < 0.05), whereas outcome expectation and expectancy did not show any significant differences. None of the variables showed any significant differences in the control group. Educational satisfaction scores were 4.38 ± 0.12 (teaching and learning) and 4.14 ± 0.15 (education results). CONCLUSIONS: This study showed that improving adolescent's awareness and behavior capability has a positive effect on their dietary practices. Moreover, this study suggested that a theory-based determinant should be considered to improve dietary behavior among adolescents.

Phantom limbs are usually observed after amputation of extremities. In patients after a stroke, a similar but rarely occurring phenomenon consisting of the patient experiencing the presence of an additional limb has been described. This phenomenon, generally called supernumerary phantom limb (SPL), may be caused by lesions in the right or left cerebral hemisphere, but has been predominantly reported in patients who have had a right hemispheric stroke. We report two cases of atypical SPL and phantom limb pain (PLP) after pontine hemorrhage. The patients were treated conservatively and their symptoms lasted more than 1 month. This is the first report of SPLs after left pontine hemorrhage, and phantom perception and pain lasted longer than those in previously observed cases. Our results indicate that SPL may be more common than reported; therefore, thorough examinations are essential for the care of stroke patients.

Pulmonary arterial hypertension (PAH) is a rare but progressive and currently incurable disease, which is characterized by vascular remodeling in association with muscularization of the arterioles, medial thickening and plexiform lesion formation. Despite our advanced understanding of the pathogenesis of PAH and the recent therapeutic advances, PAH still remains a fatal disease. In addition, the susceptibility to PAH has not yet been adequately explained. Much evidence points to the involvement of epigenetic changes in the pathogenesis of a number of human diseases including cancer, peripheral hypertension and asthma. The knowledge gained from the epigenetic study of various human diseases can also be applied to PAH. Thus, the pursuit of novel therapeutic targets via understanding the epigenetic alterations involved in the pathogenesis of PAH, such as DNA methylation, histone modification and microRNA, might be an attractive therapeutic avenue for the development of a novel and more effective treatment. This review provides a general overview of the current advances in epigenetics associated with PAH, and discusses the potential for improved treatment through understanding the role of epigenetics in the development of PAH.

Respiratory gated radiation therapy and stereotactic body radiation therapy require identical tumor motions during each treatment with the motion detected in treatment planning CT. Therefore, this study developed a tumor motion monitoring and analysis system during the treatments employing RPM data, gated setup OBI images and a data analysis software. A respiratory training and guiding program which improves the regularity of breathing was used to patients. The breathing signal was obtained by RPM and the recorded data in the 4D console was read after treatment. The setup OBI images obtained gated at 0% and 50% of breathing phases were used to detect the tumor motion range in crenio-caudal direction. By matching the RPM data recorded at the OBI imaging time, a factor which converts the RPM motion to the tumor motion was computed. RPM data was entered to the institute developed data analysis software and the maximum, minimum, average of the breathing motion as well as the standard deviation of motion amplitude and period was computed. The computed result is exported in an excel file. The conversion factor was applied to the analyzed data to estimate the tumor motion. The accuracy of the developed method was tested by using a moving phantom, and the efficacy was evaluated for 10 stereotactic body radiation therapy patients. For the sine wave motion of the phantom with 4 sec of period and 2 cm of peak-to-peak amplitude, the measurement was slightly larger (4.052 sec) and the amplitude was smaller (1.952 cm). For patient treatment, one patient was evaluated not to qualified to SBRT due to the usability of the breathing, and in one patient case, the treatment was changed to respiratory gated treatment due the larger motion range of the tumor than treatment planed motion. The developed method and data analysis program was useful to estimate the tumor motion during treatment.
