PURPOSE: The study was conducted to investigate correlations between self-management and physiological measurements of patients on hemodialysis according to their age. METHODS: The subjects were 120 patients on hemodialysis at three hospitals in S and G cities. Data were collected using a structured questionnaire and medical records. The collected data were analyzed using descriptive statistics including t-test, ANOVA, and Pearson's correlation analysis with the SPSS 23.0 program. RESULTS: The levels of compliance with self-management were highest in the middle-aged group. There was no significant difference in physiological measurements between the different age groups. CONCLUSION: The results suggest that nurses should consider characteristics of different age groups to improve the levels of self-management and physiological measurements.

INTRODUCTION: The phenomenon related to sign & symptom management for end of life of the patients is of interest to researchers in nursing society today. This study was conducted to clarify and to conceptualize the factors of sign & symptom management in end of life care though nurses' perceptions on this phenomena. METHODS: The qualitative study method was used to explore the experienced nurses' perceptions related to sign & symptom management in end of life care. It included a field study carried out in South Korea using in-depth interviews with 30 experienced nurses from three nursing home facilities. RESULTS: This study identified the following categories related to end of life care with sub-categories for each category: (1) nurses' modes in identifying the signs related to patients' end of life, (2) nurses' perceived directions on patients' end of life care, (3) nurses' perceived strategies in end of life care and (4) nurses' perceived barriers in end of life care. CONCLUSION: Through this study, characteristics of the way nurses' provide for patients' end of life care are identified, along with how nursing decisions are made to manage the sign & symptom indicating patients' end of life.

PURPOSE: The purpose of this study was to develop a computer decision making support system that enables nurses to utilize the computer in selecting the best decision for pain management for patients with dementia institutionalized in nursing homes. METHODS: To formulate the protocol for the management of patients' pain, the researcher analyzed content of interviews with 30 nurses in three nursing homes and an expert group. A decision support computer program was formalized based on existing protocols. To evaluate the effectiveness and applicability of the system, analysis of data on patient pain management and nurse satisfaction with the system were done after the formalized decision support computer program was complete. RESULTS: The decision support computer program for pain management for institutionalized patients with dementia was finalized after adjustments following the evaluation. Nurse satisfaction with the program was moderate. It also provided opportunity to reassess thinking about pain and pain management. CONCLUSIONS: The results indicate that this program provides nurses with useful knowledge for pain management in institutionalized patients with dementia and aids in decision making in nursing practice in nursing home.

Purpose: The gold standard for assessing pubertal activation is the gonadotropinreleasing hormone (GnRH) stimulation test (GnRHST), which is invasive, timeconsuming, and inconvenient. This study evaluated whether a single random measurement of urinary luteinizing hormone (LH) concentration could substitute for the GnRHST in diagnosing and monitoring central precocious puberty (CPP) in girls. Methods: Fifty-five girls with breast buds before 8 years of age were assessed by both the GnRHST and urinary gonadotropin assays. Based on the GnRHST results, 29 girls were assigned to the CPP group (peak LH≥5 IU/L), and 26 were placed in the premature thelarche (PT) group (peak LH<5 IU/L). Auxological data and urine and serum samples were collected at baseline and after treatment with a GnRH agonist for 12 and 24 weeks. Results: Although the auxological data did not differ between the 2 groups, the serum levels of insulin-like growth factor-1, basal LH, follicle-stimulating hormone (FSH), estradiol, and peak LH; urinary LH; and peak serum LH/FSH and urinary LH/FSH ratios were higher in the CPP group than in the PT group. Pearson correlation analysis showed a positive correlation between the urinary and serum LH concentrations (r=0.660, P<0.001). Receiver-operating characteristic curve analyses showed that a urinary LH concentration of 0.725 IU/L was a cutoff that significantly predicted positivity on the GnRHST. Urinary LH and FSH concentrations declined significantly during GnRH agonist treatment. Conclusion A single, random measurement of urinary gonadotropin concentration could be a reliable tool for initial screening and therapeutic monitoring of CPP in girls.

Clostridium ramosum is Gram-positive anaerobic bacillus and is known as a non-pathogenic enteric bacterium. It is a member of the RIC group, which is a subgroup of Clostridium having atypical characteristics. Rarely, it has been reported as a pathogen of otitis media in young children or the cause of infection in immunosuppressed adults. Here, we report the first two Korean cases of C. ramosum bacteremia in colon cancer and pressure sore cases, respectively.

PURPOSE: The purpose of this study was to propose and test a predictive model that could explain and predict nursing productivity. METHODS: A survey using a structured questionnaire was conducted with 360 nurses in Korea. The data were analyzed using SPSS Windows 18.0 and AMOS 19.0 program. RESULTS: Based on the constructed model, burnout and organizational commitment were found to have direct effects on nurses' turnover intention and nursing productivity. While nursing work environment was found to have indirect effects on nurses' turnover intention and nursing productivity. CONCLUSION: This structural equational model is a comprehensive theoretical model that explains the related factors and their relationship with nursing productivity. Comprehensive organizational interventions to improve nursing productivity should focus on improving the nursing work environment. Findings from this study can be used to design appropriate strategies to decrease nurse turnover in Korea. Further studies are needed to prospectively verify these causal relationships with larger samples.

A 25-year-old Korean woman was referred for uncontrolled hypertension. Laboratory examination revealed increased plasma renin activity and microscopic hematuria. Computed tomography demonstrated compression of the left renal vein (LRV) between the aorta and superior mesenteric artery; however, both renal arteries were intact and there was no adrenal mass. Renal vein catheterization showed external compression with a pressure gradient of up to 8 mm Hg between the LRV and the inferior vena cava. Plasma renin activity in the LRV was almost five times higher than that in the right renal vein. In this patient, renin-dependent hypertension was caused by renal congestion due to LRV obstruction.

PURPOSE: We prospectively evaluated the diagnostic efficacy of the BTA TRAK assay according to the stage, grade and hematuria in detecting primary and recurrent bladder cancer, and compared results with voided urine cytology. MATERIALS AND MTHODS: Urinalysis, cytology and BTA TRAK assay were performed simultaneously with the single voided fresh urine samples from 130 subjects. The sensitivity and specificity of the BTA TRAK assay were compared to those of urine cytology and analyzed according to the stage or grade. The subjects were also divided into 4 groups according to the degree of hematuria and the influence of hematuria on the result of the BTA TRAK assay was evaluated. RESULTS: The overall sensitivity and specificity of the BTA TRAK assay for detecting bladder cancer were 82.8% and 65.3%, respectively and those of urine cytology were 44.8% and 100%. The sensitivity of the BTA TRAK assay was significantly higher than that of urine cytology in bladder cancer with lower stage and grade. On univariate and multivariate analysis, gross hematuria and the presence of bladder cancer affected the results of the BTA TRAK assay significantly. In cases following after transurethral resection of bladder tumor (TURB), the sensitivity and specificity of the BTA TRAK assay for detecting recurrent bladder cancer were 100% and 79.5%, respectively. CONCLUSIONS: The BTA TRAK assay was more sensitive but less specific than voided urine cytology. Because gross hematuria affected the result of the BTA TRAK assay independently, it appears reasonable to delay the BTA TRAK assay until gross hematuria subsides in cases with gross hematuria. In cases following after TURB, the BTA TRAK assay appears to be useful for detecting recurrent bladder cancer.
