ABSTRACT
PURPOSE: The purpose of this study was to identify the influence of the ego-resilience and social support on the depression among hospital nurses. METHODS: The subjects of this study were 369 nurses in a hospital. We used the self-reported questionnaire to assess the level of ego-resilience, social support and depression of hospital nurses. The data were analyzed using descriptive statistics, frequency, t-test, ANOVA and logistic regression. RESULTS: The mean scores of ego-resilience, social support and depression were 42.6, 28.3 and 14.1, respectively. When scores of ego-resilience and social support were high, the level of mild and major depression of subjects decreased. The influencing factors of depression level were the department of work, ego-resilience and social support. CONCLUSION: The findings suggest that developing programs to improve ego-resilience and social support might be useful. Further study is required to justify the scale on ego-resilience and social support.

PURPOSE: The purpose of this study was to identify the effects of the social support and ego-resilience on the nursing performance among hospital nurses. METHODS: The subjects of this study were 369 nurses in a senior general hospital. We used the self-reported questionnaire to assess the level of ego-resilience, social support and nursing performance of hospital nurses. The data were analyzed using descriptive statistics, frequency, t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression. RESULTS: This study showed the positive relationship between the social support and ego-resilience on tne the nursing performance of hospital nurses. The higher group of the social support and ego-resilience showed the more performance of hospital nurses. And, the influencing factors on the performance are age, ego-resilience, social support, night working days a month in the order. CONCLUSION: Further studies will be needed to promote the performance of nurse in hospital and policies to be develop to elevate the social support and ego-resilience of nurses.

PURPOSE: This study was performed to investigate the effect of shift work on diurnal blood pressure (BP) pattern in nurses. Method: We studied 20 healthy nurses engaged in 3 shift work. 24-hour ambulatory BP monitoring was performed to each nurse two times during the day and night shift. Five nurses were excluded because of inadequate BP measurement. RESULTS: All subjects were female. The mean age was 27.4 years (range: 23?33 years) and mean body mass index was 19.7 Kg/m2 (range: 18.0-21.2 Kg/m2). The changes of systolic BP (17.8+/-9.1 vs. 13.2+/- 4.7%, p=0.031), diastolic BP (22.3+/-8.7 vs. 17.3+/-9.0%, p=0.061), and heart rate (25.2+/- 5.2 vs. 12.5+/-8.7%, p=0.001) during the sleeping period were decreased after a night shift compared with day shift. The non-dipper group significantly increased from 20% to 40% after a night shift (p=0.018). CONCLUSION: Working night shift is significantly associated with non-dipper status in nurses.

PURPOSE: This study was to investigate the relationship between IBS and nurses' occupational stress. METHOD: We used the modified Rome III criteria to measure the relationship between IBS and nurses' occupational stress. This questionnaire is composed of 9 areas and 43 items related to the stress. We collected the data of 395 respondents from W hospital. The survey was done from July 10th to July 31th, 2009. RESULTS: The morbidity of IBS showed 24.3%. It was significantly influenced by night shift, and hospital visits and medication because of abdominal discomfort for the past 6 months. The causes of the nurses' occupational stress, which influenced the difference between IBS and non-IBS group, were "conflict with doctors" "difficulties in human relationships" "dealing with guardians and patients." The IBS group's stress was higher that of the non-IBS group. Also 96.9% of the IBS group and 79.3% of the non-IBS group responded there was relationship between IBS and nurses occupational stress. CONCLUSION: We found the relationship between IBS and nurses' occupational stress. And such stress could be reduced through the education about IBS.

BACKGROUND AND OBJECTIVES: Patients with chronic diabetes mellitus (DM) have an increased risk of cardiac dysfunction and mortality. There is some evidence that suggests acute hyperglycemia may cause vascular dysfunction. However, it is unknown whether acute, short-term hyperglycemia affects coronary microcirculation function in healthy subjects. The present study was undertaken to explore this issue. SUBJECTS AND METHODS: We evaluated 20 healthy males who had no history of DM or impaired glucose tolerance, ranging in age from 23 to 36 years (25.9+/-3.3 years). We checked blood sugar, 12-lead electrocardiography, pulse wave velocity, and coronary flow reserve using echocardiography during fasting, and 30, 60, 90, and 120 minutes after ingestion of 75 g of glucose orally. RESULTS: Non-significant prolongation of the QTc dispersion was observed after the 75 g glucose loading. No significant difference in the pulse wave velocity of the carotid-to-femoral artery, carotid-to-radial artery, or femoral-to-dorsalis pedis artery was observed after the 75 g glucose loading. There was a significant reduction in the coronary flow reserve at 60 (4.06+/-0.75 vs. 3.54+/-0.82, p=0.021) and 90 minutes (4.06+/-0.75 vs. 3.59+/-0.63, p=0.021) after the 75 g glucose loading compared to that on fasting. CONCLUSION: The results of this study suggest that acute exposure to high circulating glucose levels does not affect heterogeneity of the ventricular repolarization or arterial stiffness, but it does reduce the coronary flow reserve in healthy young men.

BACKGROUND AND OBJECTIVES: The mobilization of circulating endothelial progenitor cells (EPCs) might represent a useful strategy for the clinical therapy of ischemic heart disease. We examined the effect of early statin therapy before reperfusion therapy on the circulating EPCs during the acute phase in patients with acute myocardial infarction (AMI). SUBJECTS AND METHODS: A total of 84 consecutive AMI patients undergoing primary percutaneous coronary intervention (PCI) within 24 hours of pain onset were included in this study. We randomly divided the patients into 3 groups according to rosuvastatin therapy before PCI: the control group (n:27, 19 males and 8 females, 58+/-2 years of age), the rosuvastatin 10 mg group (n: 28, 21 males and 7 females, 58+/-3 years of age) and the 40 mg group (n: 29, 23 males and 6 females, 59+/-2 years of age). The circulating EPCs and high sensitivity C-reactive protein (hs-CRP) levels were analyzed on admission and at 1, 3, 5, 7 and 30 days after PCI. The circulating EPCs were measured by flow cytometry as the CD45(low)CD34+VEGFR2+ cells. RESULTS: The circulating EPCs peaked on day 3 after PCI, whereas the increment of circulating EPCs was significantly suppressed in the rosuvastatin 10 mg and 40 mg groups compared with the control group on day 3 (control vs rosuvastatin 10 mg vs rosuvastatin 40 mg: 0.072% vs 0.067% vs 0.061%, respectively, p=0.002) and day 5 (0.068% vs 0.060% vs 0.058%, respectively, p=0.029). The level of hs-CRP markedly increased from day 1 and this peaked on day 3 after PCI. Early statin therapy significantly suppressed the elevation of hs-CRP compared with the control group on day 1 (24.36 mg/L vs 17.88 mg/L vs 13.08 mg/L, respectively, p=0.035) and on day 3 (30.15 mg/L vs 22.78 mg/L vs 17.16 mg/L, respectively, p=0.034). There was a statistically significant correlation between the circulating EPCs and the hs-CRP (r=0.349, p=0.007). CONCLUSION: In the AMI patients, the early stain therapy before reperfusion therapy didn't increase the mobilization of circulating EPCs, but it suppressed the elevation of hs-CRP. This data suggests that the mobilization of circulating EPCs may be related to systemic inflammation during the acute phase in patients with AMI.

BACKGROUND AND OBJECTIVES: Vitamin C, water-soluble antioxidant, has been reported to restore coronary microcirculatory responsiveness and impaired coronary flow reserve in smokers. However, the effect of high dose of vitamin C on coronary circulation is unclear in nonsmokers. METHODS: We used transthoracic echocardiography to measure the coronary flow reserve, an integrated measure of coronary flow in 20 male healthy nonsmokers (26+/-3 years) before and after administration of the high dose of vitamin C. RESULTS: The coronary peak diastolic velocity was increased by 14.8% after administration of antioxidant vitamin C, whereas the coronary flow reserve did not changed. CONCLUSION: High dose of vitamin C acutely increases the coronary flow velocity without restoration of coronary flow reserve in male healthy nonsmokers.
