The purpose of this study was to identify the experience symptoms and severity of hemodialysis patients and to determine the effects of each symptom on health related quality of life. This research involved 102 patients who were receiving hemodialysis at one university hospital and two Kidney Center in D city. Data collection were collected from April to May 2014. Data analysis was performed by SPSS/WIN 18.0 using ANOVA, t-test, Pearson correlation and stepwise multiple regression. Fatigue was the highest among symptoms on hemodialysis patients and dry skin, itching was in order. Factors affecting health related quality of life were income and symptoms level. These factors explain 42.2% of the variance in health related quality of life. Based on the results, it is necessary to develop various programs and apply for nursing interventions to alleviate the experience symptoms and severity and expand support in social service perspective in hemodialysis patients. Especially, we suggest that further research for developing nursing interventions for relieving fatigue, itching, and sleep disorders of hemodialysis patients.

Salinity gradient power (SGP) has attracted significant attention because of its high potential. In this study, we evaluate reverse electrodialysis (RED) with various compositions of available resources. The polarization curve (I-V characteristics) shows linear behavior, and therefore the power density curve has a parabolic shape. We measure the power density with varying compartment thicknesses and inlet flow rates. The gross power density increases with decreasing compartment thickness and increasing flow rate. The net power density, which is the gross power density minus the pumping power, has a maximum value at a compartment thickness of 0.2 mm and an inlet flow rate of 22.5 mL/min. The power density in RED is also evaluated with compositions of desalination brines, seawater, river water, wastewater, and brackish water. A maximum power density of $1.75W/m^2$ is obtained when brine discharged from forward osmosis (FO) and river water are used as the concentrated and the diluted solutions, respectively.

In this study, 46 patients from a local hemodialysis center were enrolled to assess the effects of a self-motivated virtual reality (VR) exercise program on the heart rate variability and quality of life control in hemodialysis patients. The VR group (n = 23) completed a VR exercise program, where the subjects performed the exercise 40 min per session, 3 sessions per week, for 8weeks. After the exercise program, the heart rate variability and quality of life were measured. The VR group showed significant improvement in the heart rate variability and quality of life. The self-motivated VR exercise program provided both the role of supervisor as well as feedback, which is important for hemodialysis patients.Therefore, a self-motivated VR exercise program may be a useful tool for improving the psychosocial function in chronic disease patients undergoing hemodialysis.

This was a descriptive study to investigate the effect of social support and health literacy on sick role behaviors in hemodialysis patients. A total of 149 outpatients receiving regular hemodialysis at four dialysis centers located in J city were surveyed. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and multiple linear regression. Factors including social support (β=.37, p<.001), health literacy (β=.16, p=.035), and religion (others) (β=-.25, p=.001) had an effect on sick role behavior. The explanatory power of model in this study was 22.0%. Therefore, the improvement of sick role behavior in patients undergoing hemodialysis requires specific strategies and interventions that are effective in increasing the social support and health literacy.

Chronic diseases is being increased attention to threatening the elements healthy life of elderly population in modem society. Especially, Chronic diseases caused by diabetes and hypertension is destroyed kidney. In this case, subjective symptom is not little. So if health is worsened, hemodialysis, artificial organs, transplant an organ etc. should be treated as a dangerous diseases. Therefor, a patients receiving hemodialysis of diabetes and hypertension studied on the effects to regularity of amplitude and rate vibration of vocal cords in hemodialysis in this paper. To do this, a diabetic and hypertensive patients don't have a problem with pronunciation selected as of the subjects and their voices collected before and after hemodialysis. We studied on the effects of voice analysis to apply regularity of amplitude and rate vibration of vocal cords. In conclusion, we extracted a result that voice after than before hemodialysis is relatively low in voice measures values a regularity of amplitude and rate vibration of vocal cords.

The purpose of this case report was to present the treatment of continuous renal replacement therapy (CRRT) in dogs with end-stage CKD with uncontrolled uremia. Hemodialysis were carried out 6 patients who failed to improve clinical status with conventional management for CKD. Four dogs with urea reduction ratio (URR) range of 57-72% and 1 dog with URR of 37.3% showed good outcome with decreasing tendency of pre-dialysis Therefore, we suggest that CRRT could be recommended for use in CKD dogs with uncontrolled azotemia or uremia and should be monitor carefully throughout the CRRT.

Purpose: This study was designed to test structural equation modeling of the quality of life of pre-dialysis patients, in order to provide guidelines for the development of interventions and strategies to improve the quality of life of patients with Chronic Kidney Disease (CKD). Methods: Participants were patients who visited the nephrology outpatient department of a tertiary hospital located in Seoul. Data on demographic factors, social support, nutritional status, physical factors and biobehavioral factors and quality of life were collected between March 4 and March 31, 2011. Results: In the final analysis 208 patients were included. Of the patients 42% were in a malnourished state. Anxious or depressed patients accounted for 62.0%, 72.6%, respectively. Model fit indices for the hypothetical model were in good agreement with the recommended levels (GFI=.94 and CFI=.99). Quality of life in pre-dialysis patients with CKD was significantly affected by demographic factors, social support, nutritional status, physical factors and biobehavioral factors. Biobehavioral factors had the strongest and most direct influence on quality of life of patients with CKD. Conclusion: In order to improve the quality of life in pre-dialysis patients with CKD, comprehensive interventions are necessary to assess and manage biobehavioral factors, physical factors and nutritional status.

Purpose: To examine the quality of life in pre-dialysis patients with chronic kidney disease. Methods: The subjects were 91 patients who visited the nephrology outpatient department of a tertiary hospital located in Seoul. Data on demographic and clinical characteristics, and quality of life (QOL) were collected between July 19 and 23, 2010. The relationship between QOL and various Stages of dependence on glomerular filtration rates (GFRs) and factors related to QOL were investigated. Collected data was analyzed with the SPSS WIN 12.0 program. Results: There was a significant difference in the quality of life of the subjects in different stages (F=18.12, p<.001). The Scheffe post hoc test confirmed that patients at higher stages had a lower level quality of life. In addition, GFRs, uremic symptoms, gender and age predicted value accounted for 38.5% of the variance on QOL (F=25.09, p<.001). Conclusion: Strategies to develop a systematic management program for improving QOL of pre-dialysis patients are urgently needed.

Infective endocarditis that involves the right side of the heart has been estimately 5% of all cases of infective endocarditis. It has been shown that about 70% of right-sided heart infective endocarditis cases have preexisting congenital heart disease or acquired valvular lesion. It would occur in intravenous drug users or end-stage renal disease patients with indwelling venous dialysis catheter. Antibiotic therapy is more effective in the right and, when it fails, the consequence of valve disruption and emboli are less. Patients receiving long-term hemodialysis are a unique population with regard in the risk of bacteremia and subsequent infective endocarditis. We experienced one case of the active infective endocarditis with right atrial vegetation without tricuspid or pulmonary valve involvement in patient with end-stage renal disease receiving long-term hemodialysis, who needed surgical correction after medical treatment failure. Then we reported it with references that right-sided heart infective endocarditis is rare, but difficult to diagnose, life-threatening because of delayed medical treatment.
