This study was to investigates the effects of verbal abuse experience, emotional labor and nursing practice environment on job stress of nurses in hemodialysis units. Participants were 169 hemodialysis nurses. Data were collected with structured qustionnaires from March 1 to March 30, 2021. Data were analyzed SPSS 23.0 program for descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Factor affecting the job stress of hemodialysis nurses were emotional labor(β=.354, p<.001), verbal abuse(β =.255, p=.005) and nursing practice environment(β=-.214, p<.001). Therefore, in order to manage the job stress of nurses in hemodialysis unit, it is necessary to prepare measures to reduce verbal abuse experience, emotional labor and create a positive nursing working environment.

Background: Left ventricular diastolic filling is an important determinant for maintenance of cardiac output during hemodialysis. Few investigators have studied the influence of hemodialysis on diastolic function. To evaluate the change of left ventricular systolic and diastolic function. we performed M-mode and Doppler echocardiographic studies before and after hemodialysis. Methods: The study population consisted of 30 patients(15 patients were male, mean age $45{\pm}10$ years) with CRF on maintenance hemodialysis. They have normal left ventricular systolic function(Fractional shortening>30%) and no evidence of valvular heart disease or regional wall motion abnormalities. The ejection fraction (EF) was measured using M-mode echocardiography and Doppler indices such as peak E velocity, peak A velocity, isovolumetric relaxation time(IVRT), deceleration time(DT). and left ventricular ejection time(LVET) obtained from Doppler echocardiography. The index of myocardial performance (IMP) was calculated from each of the Doppler velocity indices. Results: The weight reduction after hemodialysis was $2.1{\pm}1.0kg$(p<0.0001), After hemodialysis, there was some decrease in blood pressure(p<0.05), but no significant change in heart rate, EF and fractional shortening, mean VCF, peak A velocity, and DT. And significant reduction in peak E velocity, E/A ratio(p<0.0001. p<0.001), and significant increase in IVRT and IMP(p<0.05, p<0.0001) were noted. Conclusion: In conclusion, preload reduction is the main mechanism that accounts for changes in Doppler diastolic indices after hemodialysis. And an increased IMP suggests that diastolic function may be aggravated after hemodialysis, and that implies impaired left ventricular filling and disturbed left ventricular compliance.

Purpose: This study aims to examine the effect of increased physical activity (PA) regarding health-related quality of life (QOL) and nutrition intake in hemodialysis patients. Methods: The research was quasi-experimental using pre-test and posttest design. The participants were 60 patients, 30 each in the experimental and control group. The program was up to eight weeks long and involved two kinds of aerobic exercises: intradialytic aerobic exercise to be performed thrice a week and walking for up to seven days a week. The 60 patients undergoing hemodialysis for end-stage renal disease underwent assessment of International Physical Activity Questionnaires (IPAQ), 24-hour diet recall and a 12-item short-form health survey (SF-12; physical component summary score(PCS) and mental component summary score(MCS)) before and after the exercise program. Nutrition intake was assessed using CAN-2.0. Data were analyzed using descriptive statistics, independent t-test, 𝑥2 test, and Mann-Whitney U test. Results: In the experimental group, PA post-test scores were also significantly higher than the pre-test scores and the levels of physical component summary score (PCS) in QOL were significantly improved post-test, but the scores on nutrient intake did not improve. The levels of PCS were significant correlations animal protein, manganese, selenium, and Vitamin C. Although there was no group effect, total calorie of nutrition intake was higher than the comparison group. Conclusion: Combined intradialytic exercise and walking was found to be effective on PA, and PCS in QOL. Therefore, the findings of the current study may provide an appropriate guidance for encouraging exercise by hemodialysis patient.

This paper describes the experience of the dietary adaptation of patients undergoing peritoneal dialysis due to end-stage renal failure by identifying the meanings and structure of the experience. In the research method, the data from nine patients were collected using individual in-depth interviews and analyzed using Colaizzi's phenomenological method. The experience of the dietary adaptation of participants undergoing peritoneal dialysis was organized into four theme-clusters and 15 themes. These four theme-clusters were characterized as follows: 'the double sufferings of peritoneal dialysis process and dietary adaptation', 'vague and ambiguous diet management', 'the hardship of diet management felt by experiencing diet using one's body', and 'realizing the importance of diet management with peritoneal dialysis, resetting one's goal in life'. This paper describes the dietary adaptation process experienced by peritoneal dialysis patients was a process of adhering to a better life, even though it was the double sufferings of peritoneal dialysis process and dietary adaptation. In conclusion, the findings in this study provide a deep understanding of the lived experience of the dietary adaptation in peritoneal dialysis patients and should help in the development of tailored diet interventions for patients on peritoneal dialysis.

Purpose : Limited information is available on experiences of intravenous iron treatment in children. In this study, iron sucrose was administered intravenously to determine its effect, the factors predicting outcome, and safety in children on chronic dialysis. Methods : Twenty-one children whose serum ferritin levels were less than 100 ng/mL or transferrin saturations (TSAT) were less than 20% were enrolled. In 12 children on peritoneal dialysis (PD), the drug was infused intravenously as 200 mg/$m^2$ ($\leq$200 mg) at week 0, 2, 4, and 6. In 9 children on hemodialysis (HD), it was given intravenously as 8 weekly doses of 3 mg/kg ($\leq$100 mg) through week 0-7. Results : After treatment, serum ferritin levels increased significantly in both groups, and TSAT rose significantly in PD group. However, hemoglobin level did not rise significantly in both groups. Children with baseline hemoglobin less than 10 g/dL or baseline TSAT less than 20% showed significantly higher rise of hemoglobin after intravenous iron treatment. To the contrary, those with higher baseline hemoglobin and TSAT levels displayed higher rise in serum ferritin after the treatment. Although no serious adverse event occurred, TSAT levels exceeding 50% were noted in 6 patients in PD group. Conclusion : This suggests that 3 mg/kg/week of intravenous iron sucrose can be used safely in children on chronic HD, but 200 mg/$m^2$ every other week may incur excessive TSAT level in some patients on chronic PD.

This study was conducted to identify the conceptual definitions and attributes of fatigue in hemodialysis patients based on the Hybrid Model of concept development. The Hybrid Model was used to investigate the main attributes and indicators of the concept by applying three stages. After a literature review, data were collected through observation and interviews including qualitative research in the field work stage. The participants included 10 patients in hemodialysis center of two hospitals in Gwang-ju, Korea. The attributes of fatigue concept in the hemodialysis patients were divided into four dimensions, physical activity, affective mood, social role, and cognitive reflection. The definition of fatigue by hemodialysis patients was defined as 'subjective feeling usually experienced in four dimensions during the process to recognize and adjust energy deficiency and limited functions caused by uremia and repeated hemodialysis for chronic renal failure'. Considering the dimensions and attributes derived from this study, it may be possible to develop an effective intervention program for fatigue in hemodialysis patients.

The demands for specially trained hemodialysis nurses are increasing as the population requiring maintenance hemodialysis expands. However, there has been no standardized training program for hemodialysis nurses in South Korea. The study was conducted to develop and evaluate a hemodialysis nurse educational program (HNEP). The effects of education using the HNEP were assessed by levels of hemodialysis-specific knowledge, self-efficacy and satisfaction. A total of 25 registered nurses participated in the HNEP which consists of 20 week education (classroom theory for 10 weeks and clinical practice for 10 weeks) between April and September, 2011. Knowledge levels were compared before and after the HNEP using paired t-test. Self-efficacy and satisfaction levels were also evaluated after the program using a scale of 1-5, 5 being the highest and 1 being the lowest. Knowledge levels were significantly increased after the HNEP (Mean=13.96 vs. 17.80, t=-7.748, p=<.001). Self-efficacy and satisfaction levels with the program were high, $3.90{\pm}0.42$ and $4.02{\pm}0.77$, respectively. These findings suggest that the HNEP improved hemodialysis-specific knowledge, and levels of self-efficacy and satisfaction with the HNEP were reasonably, among the participants.

Background: Preoperative elevated serum creatinine values are associated with increased risk for both morbidity and mortality in patients undergoing on-pump coronary artery bypass surgery (CABG). We investigated the postoperative changes of renal function and proper management in the patients. Material and Method: Among 74 consecutive patients who underwent isolated on-pump CABG, 17 patients with increased serum creatinine level $(creatinine\;\geqq\;1.5\;mg/dL)$ within preoperative one week wereincluded in the study. Seven patients showed pre­operative serum creatinine level of 2.0 mg/dL or higher, and 3 of them had been undergoing hemodialysis. Preoperative hemodialysis was performed in the 3 patients due to end-stage renal failure (ESRD) the day before the operation. We started peritoneal dialysis immediately after the cardiopulmonary bypass in patients with ESRD or postoperative acute renal failure if it was necessary to remove intravascular volume and lower serum creatinine level. Result In most of the patients with CABG, postoperative serum creatinine level increased and recovered to the preoperative level at the discharge. In 2 of the 4 patients with serum creatinine level of 2.0 mg/dL or higher and 3 patients with ESRD, intravascular volume, serum creatinine level and serum electrolyte were controlled with peritoneal dialysis. Conclusion: Postoperative serum creatinine level increased transiently in most of CABG patients, and intravascular volume and serum creatinine level were controlled by peritoneal dialysis only in the patients with acute renal failure postoperatively and those depending on hemodialysis.

Background/Aims: Assessment of fluid status in hemodialysis patents is very important. Overhydration in hemodialysis is associated with generalized edema, cardiovascular complications, and hypertension. The aim of this study was to determine the factors correlated with mortality of hemodialysis patients, assessing body muscle mass and fluid status using bioelectrical impedance analysis (BIA). Methods: This study enrolled 93 patients who underwent hemodialysis between January 2010 and May 2015 at CHA Bundang Medical Center. Medical records of enrollees up to June 2017 were reviewed retrospectively. These included laboratory results (serum albumin, C-reactive protein [CRP], lipid profile, etc.) and BIA data (extracellular water, intracellular water, total body water, soft lean mass, fat free mass, skeletal muscle mass, etc.). Results: Eleven of 93 patients had expired by May 2017. Among the surviving subjects, mean age was younger, CRP levels were lower, albumin levels were higher, and extracellular water/total body water (ECW/TBW) ratios were lower than in the expired patient group. Kaplan-Meier survival analysis revealed that overhydration (ECW/TBW > 0.4) was associated with higher mortality. Conclusions: In hemodialysis patients, overhydration is an important factor in mortality, and BIA could be a reliable modality in its assessment. We suggest that, for hemodialysis patients, overhydration is more of a risk factor for mortality than is muscle wasting.
