OBJECTIVES: To explore changes in self-reported oral health in middle-aged Koreans over a period of 9 years. METHODS: This study design was a cross-sectional analysis. This study analyzed the data of 18,845 middle-aged (45-64 years) subjects who participated in 4-6th Korea National Health and Nutrition Examination Surveys (KNHANES). A complex-sample chi-square test was used to analyze self-reported poor oral health according to sex, household income, and education. A complex-sample logistic regression analysis was used to identify the changes in the factors. SPSS 23.0 and the R ver. 3.5.1 statistical package were used for the analyses. RESULTS: Poor oral health have been decreased by 5.3% over the 9-year period. Middle-aged men were more likely to report their oral health as worse than women. The lower income and education groups reported their oral health as poor compared to the higher income and education groups. The factors affecting self-reported poor oral health over the 9-year period were sex, income, and education. CONCLUSIONS: More than half of the aged population reported their oral health as poor. Oral health policies should be established for the aged population, including the middle-aged population, for long-term plans.

PURPOSE: The aim of this study was to analyze the effects of incivility experienced by clinical nurses on their job stress, and to identify the moderating effects of self-efficacy on the relationship between job stress and incivility. METHODS: A structured self-report questionnaire was used to measure job stress, incivility and self-efficacy. Data were collected from 140 nurses currently working in three general hospitals of more than 300 beds. Data were analyzed using descriptive statistics, ANOVA, Scheffé test, Pearson correlation coefficient, hierarchical multiple linear regression with the SPSS Version 19.0 program. RESULTS: Incivility from supervisors, patients and patients' families showed a significant effect on job stress and self-efficacy had an effect on incivility from patients and patients' families and also incivility from doctors and job stress. These variables have total explanatory power of 46.6% on job stress. CONCLUSION: The results indicate a need to recognize the seriousness and damage of incivility in order to reduce hospital nurses' job stress and to awaken nurses to the relationship of stress and incivility and establish institutional programs to combat incivility. Moreover, there is also a need to improve self-efficacy on the ward through hospital education and coaching.

Varicose veins refer to tortuous engorged veins on the lower extremities. Although this is a common condition observed in clinical practice, objective diagnosis is important for optimal treatment.Current Concepts: Thorough physical examination is the first key step for diagnosis of varicose veins. Both legs should be examined between the inguinal region and the feet with the patient in an erect position. The presence and location of venous reflux should be confirmed using duplex ultrasonography (DUS), which serves as a simple, non-invasive modality to assess both the anatomy and physiology of leg veins. Reflux is defined as duration of retrograde flow greater than 0.5 seconds in superficial veins, 0.35 seconds in perforating veins, and 1.0 seconds in deep veins. Computed tomography venography can be used in selective cases as a complementary tool to obtain objective images of all varicose veins; however, this imaging modality cannot confirm venous reflux.Discussion and Conclusion: DUS is a key diagnostic tool for varicose veins. However, DUS results are operator dependent; therefore, this procedure should be performed by experienced technologists or clinicians, based on guidelines. The location and duration of reflux should be recorded.

Purpose: This study was conducted to develop the contents of disaster nursing education in community health nursing at universities. Methods: To validate contents, the Delphi method was used. We categorized two domains(indirect disaster management and direct disaster management) and developed 48 draft items. This study applied two round surveys and 23 experts participated in this study. The content validity was calculated using content validity ratio and coefficient of variation. Results: Indirect disaster management domain was composed of three categories including 12 items: 1) Understanding of the disaster, 2) disaster management system, and 3) response by disaster stage and recovery. Direct disaster management domain was composed of nine categories including 30 items: 1) Ethical considerations, 2) communication in disasters, 3) nursing activity by disaster stage, 4) emergency nursing in disasters, 5) patient severity classification in disasters, 6) disaster nursing for vulnerable groups, 7) disaster nursing for victims, 8) psychosocial nursing and health in disasters, and 9) cases of disaster nursing in communities. Conclusion This Delphi study identified the contents of disaster nursing education curriculum, and confirmed the validity for disaster education program in community health nursing. Based on the results, it will be helpful for training the disaster nursing and improving the competency on disaster nursing of the nursing students.

PURPOSE: The purpose of this study is to examine effects of a multifactorial program for preventing the frailty of older adults and effects of a follow-up program applying a capacity building strategy. METHODS: A quasi-experimental pretest-posttest design was used for the nonequivalent control group. The follow-up group (n=75) and non-follow-up group (n=68) received the same multifactorial program comprising muscle strength exercise, cognitive training, and psychosocial programs for 12 weeks. After completion of multifactorial program, the follow-up group took follow-up programs applying the capacity building strategy for following 12 weeks. The data of physical function, cognitive function, and psychological function, and self-rated health were collected from both groups three times: before intervention, after intervention, and 12 weeks after intervention. The data were analyzed using χ2 test and t-test. RESULTS: In comparison with the non-follow-up group, the scores of Timed Up & Go Test, and physical activities energy expenditure were significantly improved in the follow-up group. CONCLUSION: These results indicate that a multifactorial program with follow-up adapting the strategies of capacity building for the older adults group is feasible to prevent the physical frailty in community.

PURPOSE:This study was designed to know the clinical significance and risk factors of hyperkalemia in very low birth weight infants (VLBWI). METHODS:We compared the incidence of hyperkalemia and its associated ECG abnormalities and mortality rate according to birth weight (102 of less than 1,000 g vs. 328 of 1,000 to 1,500 g) in 430 VLBWI who were born from Jan. 2000 to July 2004, retrospectively, and also compared the several parameter according to serum potassium (35 of hyperkalemia vs. 11 of normokalemia) in 49 selected VLBWI who need mechanical ventilation for respiratory distress without oliguria within 72 hours of life to know the risk factors of hyperkalemia. RESULTS:Overall incidence of hyperkalemia in VLBWI was 21.1%, and was significantly higher in below 1,000 g than in 1,000 to 1,500 g (32.4% vs. 17.7%, P<0.05). Hyperkalemia associated ECG abnormalities, life-threatening cardiac arrhythmia, and death were also significantly higher in below 1,000 g. There were no significant differences in maternal or infant's characteristics, laboratory findings and clinical conditions between hyperkalemic vs. normokalemic group. The incidence of cardiac arrhythmia and mortality rate were also significantly higher in hyperkalemic group. CONCLUSION:Early onset nonoliguric hyperkalemia is often associated with life- threatening cardiac arrhythmia and death in VLBWI, especially less than 1,000 g. Although perinatal risk factors were not found in this study, prospective study is needed to establish the preventive strategy and to improve the outcome.

Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.
