Electrodialysis (ED) is essential in separating ions through an ion exchange membrane. The disposal of brine generated from seawater desalination is a primary environmental concern, and its recycling through membrane separation technology is highly efficient. Alkali is produced by several chemical industries such as leather, electroplating, dyeing, and smelting, etc. A high concentration of alkali in the waste needs treatment before releasing into the environment as it is highly corrosive and has a chemical oxygen demand (COD) value. The concentration of calcium and magnesium is almost double in brine and is the perfect candidate for carbon dioxide adsorption, a major environmental pollutant. Sodium hydroxide is essential for the metal carbonation process which, is easily produced by the bipolar membrane electrodialysis process. Various strategies are available for its recovery, like reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and ED. This review discusses the ED process by ion exchange membrane for alkali recovery are discussed.

Purpose: The purpose of this study was to identify the effect of auricular acupressure on pruritus and fatigue in hemodialysis patients. Methods: The study design was a randomized control group pre-post test. Initially, forty-four patients were randomly assigned to one of two groups. There was a loss of three participants assigned to the treatment group. The period of data collection was from December 2014 to March 2015. Both groups completed a pre-test. The treatment group received auricular acupressure once a week for ten weeks. Data were collected from the treatment group at two time periods: five weeks and ten weeks following initiation of the treatment protocol. Data were collected from the control group at week 5 and week 10. Data analysis was performed using IBM SPSS Statistics 21.0 program, specifically with the independent t-test and the Repeated Measures of ANOVA. Results: Auricular acupressure was effective in reducing pruritus (F=13.93, p<.001) and fatigue (F=18.33, p<.001). Conclusion: Auricular acupressure is a non-invasive simple method that can be used for the relief of symptoms reported by hemodialysis patients. This treatment modality could be used in several clinical areas.

Purpose: This study was a descriptive survey research to identify the factors that influence sick role behavior compliance in patients on hemodialysis. Methods: Structured surveys were used to collect data from 170 patients who are on hemodialysis three times a week through outpatient care at a university hospital located in G City using tools measuring resilience, family support, and sick role behavior compliance. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient, and Stepwise multiple linear regression. Results: The results showed that factors that influenced sick role behavior compliance in the subjects were in the order of family support (${\beta}=.27$, p<.001), age (${\beta}=.27$, p<.001), and resilience (${\beta}=.23$, p=.003). Resilience, family support, and sick role behavior compliance were positively correlated. Factors influencing hemodialysis patients' sick role behavior compliance included family support, age, and resilience. These variables explained 30.2% of the variance in sick role behavior compliance. Conclusion: Based on these results, care intervention and the development of a training program that involves family in the treatment plan and process to support and encourage patients are needed to increase the sick role behavior compliance in patients on hemodialysis.

Purpose : This descriptive survey aims to identify the prevalence of factors associated with sarcopenia among hemodialysis patients. Methods : The study subjects were 137 patients with chronic kidney failure undergoing hemodialysis in three artificial kidney centers in B and Y cities. Data were collected from August 1 to September 30, 2020, using the SARC-F (Strength, Assistant walking, Rising from a chair, Climbing stairs, Falls) questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), International Physical Activity Questionnaire (IPAQ-SF), Bioelectrical Impedance Analysis (BIA), and a grip dynamometer. The collected data were analyzed using t-tests, crossover analysis, and logistic regression using the IBM SPSS 23 program. Results : The prevalence of sarcopenia among hemodialysis patients, determined using the SARC-F questionnaire, was 16.1%. The associated factors of sarcopenia among hemodialysis patients were found to be gender (OR=6.44, p =.002), age (OR=1.07, p =.015), nutritional status (OR=10.37, p =.027), and albumin level (OR=0.10, p =.014). These findings are supported by an explanatory power of 46.3% (p =.597). Conclusion : The identified risk factors for sarcopenia in hemodialysis patients were; sex, age, nutritional status, and albumin level. The findings of this study can serve as clinical evidence for the development of an intervention program for preventing and managing sarcopenia in patients undergoing hemodialysis.

Stenosis of the central veins is a common complication in hemodialysis patients. However, cerebral venous hypertension and neurological symptoms caused by central vein stenosis are relatively rare. We present a rare case of cerebral venous hypertension in a 63-year-old male who showed venous reflux into the dural sinuses due to central venous stenosis on time-of-flight MR angiography. After management for central venous stenosis, the venous reflux disappeared.

Purpose: This study was a qualitative study to explore and understand the adaptation experiences of hemodialysis among women with End-Stage Renal Disease (ESRD) and to develop a substantive theory using the grounded theory method. Methods: Participants were 15 female patients who underwent hemodialysis for ESRD treatment from three general hospitals. The data were collected through in-depth individual interviews. Results: The adaptation experience of participants was emerged as a process of taking care and enduring. There were four adaptation stages as a negative, despair, receptive, and maintenance period in reference to hemodialysis. The causal conditions were a vague expectations of recovery and refusal to undergo hemodialysis. The core phenomenon was that of confinement to dialysis machine. The contextual conditions for this phenomenon were the loss of femininity. They used action/interaction strategies such as transition their life with a focus on hemodialysis, seeking information, and learning how to take care of their body. Through this process, they had a strong will to live or had sustained their life. Conclusion: These results indicate that there is a need for nurses to understand the different steps of adaptation experiences of the given patient population. It is necessary for nurses to support them to lead their life as much normal as possible and improve the adaptation experience of ESRD.

Emphysematous prostatitis with an abscess is an extremely rare but lethal infection, characterized by the accumulation of gas and purulent exudates. Due to its rarity, severity, and nonspecific presentation, prompt diagnosis and treatment are crucial to achieve favorable clinical outcomes. This report presents a 43-year-old male with hemodialysis-dependent end-stage kidney disease who reported a 3-day history of fever, urinary incontinence, dysuria, and dyspnea. His condition rapidly deteriorated due to septic shock caused by emphysematous prostatitis with an abscess. Following extensive treatment including long-term parenteral antibiotics, polymyxin B hemoperfusion filter treatment, abscess drainage via transurethral resection of the prostate, and suprapubic cystostomy, the patient successfully recovered.

Objective: Restless legs syndrome (RLS) is known to be associated with chronic renal failure (CRF) patients on hemodialysis, however the prevalence of RLS in CRF patients on hemodialysis is variable due to different diagnostic criteria or dialysis technique. A few reports have indicated the association between RLS symptom and lower life quality in CRF patients on hemodialysis. This study aims to investigate the prevalence of RLS and its association with the quality of life in CRF patients of a single dialysis unit in Korea. Methods: A total of 83 Korean CRF patients on hemodialysis in the Korea University Hospital were examined. International Restless Legs Syndrome Study Group (IRLSSG) criteria and International Restless Legs Scale (IRLS) were used to determine the diagnosis and severity of RLS. Questionnaires including Athens Insomnia Scale (AIS), Epworth sleepiness scale (ESS), and Medical Outcome Study Form-36 (SF-36) were administered to all the patients for the assessment of sleep and quality of life. Hamilton Depression Rating Scale (HDRS) and Clinical Global Impression (CGI) were also measured for depression and status of mental illness by psychiatrist. Results: Of the 83 patients, 31 (37.3%) patients were found to have RLS and 43 (51.8%) patients met at least one of the RLS diagnostic criteria. The AIS (t=2.40, p=0.019), ESS (t=2.41, p=0.018), HDRS (t=3.85, p<0.001) and CGI (t=3.52, p=0.001) were higher in the subjects with RLS compared to other subjects. The SF-36 scores were significantly lower in the patients with RLS except physical functioning and bodily pain. Total (p=0.005), physical component (p=0.019), and mental component scores (p=0.019) of SF-36 were significantly lower in patients with more severe RLS symptoms. Conclusion: There was significant relationship between RLS and poor quality of sleep and life. More severe RLS symptom was proven to be an important factor to make a quality of life worsen.
