Purpose This study aimed to verify the potential use of postoperative pulmonary complications prediction models in patients with lung resection. Methods In this retrospective study, 1,160 patients were selected among the admitted patients who underwent lung resection surgery. The predictive validity of the Assess Respiratory Risk in Surgical Patients in Catalonia Tool (ARISCAT) and the Pulmonary Complications Risk Score (PCRS)-lung resection model were assessed based on the sensitivity, specificity, positive and negative predictive values, and Area Under the receiver operating characteristic Curve (AUC). Results Of the patients, 420 (36.2%) developed postoperative pulmonary complications after lung resection surgery within 30 days. The sensitivity, specificity, positive predictive values, and negative predictive values were 52.2%, 70.6%, 49.0%, and 74.0%, respectively, for the ARISCAT (cut-off point of 47), and 53.8%, 78.5%, 15.3%, and 95.9%, respectively, for the PCRS-lung resection model (cut-off point of 147). The AUCs were 0.65 (ARISCAT) and 0.70 (PCRS-lung resection model). Conclusion The findings indicate that the predictive validity values of the ARISCAT was sufficient, and the PCRS-lung resection model was good. However, the clinical usefulness of the models should be verified in future studies.
Purpose This study aimed to identify the prevalence of chronic diabetic complications in patients with type 2 diabetes mellitus.
Methods Data for adults aged over 30 years, who were diagnosed with type 2 diabetes mellitus and who had at least one claim for the prescription of antidiabetic medication were extracted from the National Health Insurance Service-National Health Screening Cohort in Korea from 2002 to 2015. Statistical analyses were performed using R version 3.5.1.
Results In total, 1,407 patients with type 2 diabetes mellitus without complications were extracted from the database. Patients were observed for an average of 10.43 years. The prevalence of chronic diabetic complications was 84.7% and was significantly higher for patients who were older women, who lived in the capital, and had diabetes mellitus for a longer time. The prevalence of eye disease was the highest at 42.4%, and cerebrovascular disease was the lowest at 15.1%. Cardiovascular disease, peripheral vascular disease, neuropathy, and foot ulcers often occurred between two and four years, and eye disease and nephropathy often occurred over eight years after the diagnosis of diabetes. Prior to the occurrence of nephropathy, microvascular complications such as neuropathy, peripheral vascular disease, and eye disease occurred.
Conclusion These findings provide compelling evidence of the prevalence of chronic diabetic complications based on a national database. Since a high incidence of diabetic complications occurs within a short period of time after the diagnosis of diabetes, aggressive interventions are required to prevent diabetic complications in the early stages after diagnosis.

PURPOSE The purpose of this study was to examine self care behaviors according to the risk levels of vascular complications in elderly women with hypertension. METHODS The subjects of this study were 162 women living in the community who had been diagnosed with hypertension in clinics. The data were analysed by the SPSS 10.0 program using descriptive statistics, t-test, and ANOVA with Scheff. post-hoc test. RESULTS The average self care behavior score of the elderly women was 2.79. Total self care behavior was significantly different depending on the risk levels of vascular complications such as systolic blood pressure, diastolic blood pressure, ankle-brachial index, and the framingham point score. Among sub-scores of self care behaviors, exercise management was the poorest performance compared with other self care behaviors. CONCLUSION This study proved the differences in self care behaviors according to the risk levels of vascular complications. To decrease the prevalence of vascular complication, it is necessary to develop programs specifically to enhance self care behaviors of elderly women with hypertension.
PURPOSE This study was performed to investigate the type and frequency of end colostomy-related complications and to identify the risk factors for those complications. METHODS Retrospective analysis of medical records was made in 708 patients who underwent end colostomy in Samsung Medical Center between October 1994 and February 2005. The type was divided into stomal and peristomal complications: stomal complications included bleeding, necrosis, mucocutaneous separation, prolapsed stoma, retraced stoma, stenosis, and hyperplasia; peristomal complications did peristomal varix, peristomal hernia, irritant contact dermatitis, allergic contact dermatitis, maceration, folliculitis, hyperplasia, bacterial infection, candidal infection, malignancy in the peristomal area, mechanical damage and pyoderma gangrenosum. RESULTS For stomal complications, hyperplasia was most common(9.0%). For peristomal complications, irritant contact dermatitis was developed in 17.4%. Sex and BMI were risk factors for irritant contact dermatitis, hyperplasia, peristomal hernia, flat stoma, and retracted stoma. CONCLUSION Teaching for preventing irritant contact dermatitis such as proper pouching and peristomal skin protection, and for comprehensive weight control should be emphasized on self care program for ostomates, while ostomy care nurse should take a careful consideration of preoperative ostomy site marking in female obese patients.
PURPOSE The purpose of this study was to explore the predictors of cardiovascular risk factors among type 2 diabetic patients. METHOD Data were collected from November, 2003 to June, 2004 using a physiological index and questionnaires. Patients(N=159) aged 40 and above were conveniently recruited from health care centers in B city. Data were analyzed with descriptive statistics, Pearson correlation and stepwise multiple regression using SPSS WIN 10.0 program. RESULTS The cardiovascular risk factors were negatively related with female gender, household monthly income, educational experience about diabetes, physical activity, self-care, self-efficacy and problem oriented coping, while positively related with the duration of diabetes, diabetic family history and depression. Self-care, diabetic family history, female gender, monthly household income, self-efficacy, affective-oriented coping and physical activity predicted 41.5% of the variance in cardiovascular risk factors of diabetic patients. CONCLUSION According to the findings of this study, we concluded that cardiovascular risk factors of type 2 diabetic patients are related to the modifiable and non-modifiable variables. Self-care, self-efficacy, affective- oriented coping, and physical activity were identified as modifiable variables. Intervention programs to increase those variables are warranted to reduce cardiovascular risk factors among type 2 diabetic patients.
