Purpose: This study aimed to examine the moderating effect of organizational justice on the relationship between self-efficacy and nursing performance among clinical nurses. Methods: In January 2021, a cross-sectional survey was conducted with 224 clinical nurses recruited from a university-affiliated hospital in Suwon, South Korea. Participants completed online-based, self-report structured questionnaires. Collected data were analyzed using multiple regression and a simple model of PROCESS macro with a 95% bias-corrected bootstrap confidence interval. Results: Self-efficacy and organizational justice were found to be significant predictors of nursing performance. These two predictors explained the additional 34.8% variance of nursing performance in the hierarchical regression model, after adjusting the other covariates. In addition, organizational justice moderated the relationship between self-efficacy and nursing performance among the clinical nurses. In particular, at low self-efficacy level, participants with high organizational justice had higher nursing performance compared to those with low organizational justice. Conclusion Enhancing organizational justice can be used as an organizational strategy for improving the organizational culture in terms of distribution, procedure, and interaction. Ultimately, these efforts will contribute to the improvement of nursing performance through a synergistic effect on organizational justice beyond nurses’ individual competency and self-efficacy.

BACKGROUND: Diet pattern of regular and three meals per day is commonly recommended. Studies investigated the health effect of gorging pattern of diet using meal frequency and meal skipping, but the health effect of meal calorie variation between three regular meals has never been investigated. In this study, maximum meal calorie variation was defined as subtraction calorie for a meal with minimum energy intake from calories for a meal with maximum energy intake between three meals and examined the effect of maximum meal calorie variation between three regular meals a day on cardiovascular risk factors. METHODS: A total of 4,680 healthy subjects aged 20-87 years who underwent medical screening examination, at one tertiary hospital health screening center and completed 24-hour dietary recall was included. Serum cholesterol subfractions, fasting glucose and blood pressure were measured. RESULTS: Maximum meal calorie variation was significantly related to serum concentration of total cholesterol (beta = 1.77; 95% confidence interval [CI], 0.36 to 3.18) and low density lipoprotein-cholesterol (LDL-C) (beta = 1.64; 95% CI, 0.37 to 2.91), body mass index (beta = 0.24; 95% CI, 0.12 to 0.37) and waist circumference (beta = 0.66; 95% CI, 0.34 to 0.98) after adjustment for potential confounders. CONCLUSION: This study suggests the notion that concentration of total cholesterol and LDL-C and obesity indices are related to maximum meal calorie variation between three meals, independently of energy intake and other confounding factors in free-living population.

PURPOSE: The aim of this study was to retrospectively evaluate the association of need for early relaparotomy with clinical outcomes after elective open repair of abdominal aortic aneurysms (AAAs). METHODS: A total of 292 consecutive patients who underwent elective open AAA repair at Asan Medical Center from January 2001 to December 2010 were included in this study, and we compared the demographics, clinical characteristics, related risk factors, and clinical outcomes of early relaparotomy versus nonrelaparotomy patients. RESULTS: The incidence of early relaparotomy during a single hospital stay was 4.1% (n = 12), and the most common causes were bowel ischemia (n = 5, 41.7%) and postoperative bleeding (n = 3, 25.0%). Among the demographics and clinical characteristics significantly associated with relaparotomy were: age (P = 0.025), chronic obstructive pulmonary disease (COPD) (P = 0.010), number of RBC units transfused during the AAA repair (P = 0.022) and in the following week (P = 0.005), and length of intensive care (P < 0.001) and overall hospital stay (P < 0.001). On multivariate analysis, presence of COPD (P = 0.009) and number of RBC units transfused during the AAA repair (P = 0.006) were statistically significantly associated with relaparotomy. Furthermore, early relaparotomy was associated with perioperative (within 30 days) (P = 0.048) and overall in-hospital mortality (P = 0.001). CONCLUSION: Early relaparotomy has an adverse effect on clinical outcomes: increased mortality and hospital length of stay. Presence of COPD and need for RBC transfusion are associated with early relaparotomy.

PURPOSE: The present study aimed to evaluate the risk factors and the role of graft material in the development of an acute phase systemic inflammatory response, and the clinical outcome in patients who undergo endovascular aneurysm repair (EVAR) or open surgical repair (OSR) of an abdominal aortic aneurysm (AAA). METHODS: We retrospectively evaluated the risk factors and the role of graft material in an increased risk of developing systemic inflammatory response syndrome (SIRS), and the clinical outcome in patients who underwent EVAR or OSR of an AAA. RESULTS: A total of 308 consecutive patients who underwent AAA repair were included; 178 received EVAR and 130 received OSR. There was no significant difference in the incidence of SIRS between EVAR patients and OSR patients. Regardless of treatment modality, SIRS was observed more frequently in patients treated with woven polyester grafts. Postoperative hospitalization was significantly prolonged in patients that experienced SIRS. In multivariate analyses, the initial white blood cell count (P = 0.001) and the use of woven polyester grafts (P = 0.005) were significantly associated with an increased risk of developing SIRS in patients who underwent EVAR. By contrast, the use of woven polyester grafts was the only factor associated with an increased risk of developing SIRS in patients who underwent OSR, although this was not statistically significant (P = 0.052). CONCLUSION: The current study shows that the graft composition plays a primordial role in the development of SIRS, and it leads to prolonged hospitalization in both EVAR and OSR patients.

PURPOSE: To propose a new, multivariable risk-scoring model for predicting 30-day mortality in individuals underwent repair of abdominal aortic aneurysms (AAA). METHODS: Four hundred eighty-five consecutive patients who underwent AAA repair from January 2000 to December 2010 were included in the study. Univariate and multivariate analyses were performed to evaluate the risk factors, and a risk-scoring model was developed. RESULTS: Multivariate analysis identified three independent preoperative risk factors associated with mortality, and a risk-scoring model was created by assigning an equal value to each factor. The independent predictors were location of the AAA, rupture of AAA, and preoperative pulmonary dysfunction. The multivariable regression model demonstrated moderate discrimination (c statistic, 0.811) and calibration (Hosmer-Lemeshow test, P = 0.793). The observed mortality rate did not differ significantly from that predicted by our risk-scoring model. CONCLUSION: Our risk-scoring model has excellent ability to predict 30-day mortality after AAA repair, and awaits validation in further studies.

PURPOSE: Surgery is the most common risk factor for pulmonary embolism (PE) in patients with a recent venous thromboembolism (VTE). This study reviewed clinical outcomes of preoperative inferior vena cava filter (IVCF) use in patients with acute VTE during abdominal-pelvic cancer or lower extremity orthopedic surgeries. MATERIALS AND METHODS: We retrospectively analyzed 122 patients with a recent VTE who underwent IVCF replacement prior to abdominal-pelvic cancer or lower extremity orthopedic surgery conducted between January 2010 and December 2016. Demographics, clinical characteristics, postoperative IVCF status, risk factors for a captured thrombus, and clinical outcomes were collected for these subjects. RESULTS: Among the 122 study patients who were diagnosed with acute VTE in the prior 3 months and underwent preoperative IVCF replacement, 70 patients (57.4%) received abdominal-pelvic cancer surgery and 52 (42.6%) underwent lower extremity orthopedic surgery. There were no perioperative complications associated with IVCF in the study population and no cases of symptomatic PE postoperatively. A captured thrombus in the filter was identified postoperatively in 16 patients (13.1%). Logistic regression analysis indicated that postoperative anticoagulation within 48 hours significantly reduced the risk of a captured thrombus (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.08–0.94; P=0.032). CONCLUSION: A captured thrombus in preoperative IVCF was identified postoperatively in 16 patients (13.1%). Postoperative anticoagulation within 48 hours reduces the risk of captured thrombus in these cases.
