Pentoxifylline improves anemia through its novel effect on hypoxia-inducible factor-2 alpha in hemodialysis patients: a randomized, double-blind, placebo-controlled clinical trial

ABSTRACT Objectives This randomized, double-blind, placebo-controlled clinical trial aimed to prospectively examine the effect of pentoxifylline (PTX) on hypoxia-inducible factor-2 alpha (HIF-2α) and its role in controlling anemia in hemodialysis (HD) patients. Methods Eighty patients on HD were randomized to receive 400 mg of PTX or placebo twice daily for 6 months. The hemoglobin (Hb) and other hematologic parameters, the weekly erythropoiesis-stimulating agents (ESAs), and the ESA resistance index (ERI) were assessed monthly during the study. The HIF-2α, transforming growth factor-β1 (TGF-β1), and high-sensitivity C-reactive protein (hs.CRP) were measured before and after the intervention. Results In the pentoxifylline group, an appreciable increase in Hb from 9.7 (9.3, 10.3) g/dl to 10.5 (9.3, 11.4) g/dl and hematocrit (Hct) from 31.3 (29.6, 32.4)% to 33.2 (29.4, 35.9)% was observed after one month of PTX administration, and this effect was maintained over the study time (p < 0.001). This was along with a decrease in the ESA doses required from 8000 (8000, 11500) IU/wk to 4000 (2000, 8000) IU/wk (p < 0.001), and an improvement in the ERI from 11.6 (8.07, 16.97) IU/kg/wk/g/dl to 5.79 (2.01, 10.09) IU/kg/wk/g/dl (p < 0.001). Additionally, the HIF-2α increased significantly at the end of the intervention in patients who received PTX from 3245.35 (2886.8, 4691.56) pg/ml to 7208.75 (5382, 9182.7) pg/ml, while TGF-β1 and hs.CRP decreased significantly from 657.78 (539.78, 1146.62) pg/ml and 88.08 (39.93, 100.4) mg/l to 329.94 (228.67, 793.18) pg/ml and 48.65 (34.44, 84.61) mg/l, respectively. The percent changes in HIF-2α, TGF-β1, and hs.CRP levels in the pentoxifylline group were also statistically significant in comparison with the placebo group. Conclusions PTX could be a promising agent for correcting anemia in HD patients via increasing HIF-2α levels.

Incidence of Acute Pulmonary Edema Before and After the Systematic Use of Ultrasound B-Lines

Introduction: Acute pulmonary edema (APE) due to fluid overload is considered the most feared complication in hemodialysis patients. Various diagnostic tests have been proposed to assess the fluid status in patients with end-stage kidney failure (ESKF); among these, lung ultrasound (measuring the number of B-lines) is emerging as a promising tool to identify pulmonary congestion in this patient population. Methods: We compared the incidence of APE before and after the implementation of lung ultrasound as a routine practice in our unit. The pre (from 1 January 2007 to 31 December 2008)- and post (from 1 January 2017 to 31 December 2018)-B-line implementation periods included 98 and 108 hemodialysis patients, respectively. By accurately reviewing their electronic medical records, all episodes of APE were collected. The 10-year interval between the two periods was specifically chosen to ensure no overlap between patients of the two cohorts whereas the single-center design was adopted to minimize the influence of center effect on the study results. Results: APE episodes occurred more frequently in patients from the pre-B-line implementation group (18/98, i.e., 18.4%) compared with those from the post B-line implementation group (6/108, i.e., 5.5%) (p = 0.004). An analysis based on repeated APE events showed that the incidence rate of APE was significantly higher during the pre-implementation period (2.0 APE episodes per 100 person-months, 95% CI: 1.4–2.7) than during the post-implementation period (0.3 APE episodes per 100 person-months, 95% CI: 0.1–0.7), with an incidence rate ratio (post- versus pre-) of 0.17 (95% CI: 0.07–0.40; p &lt; 0.001). The odds of experiencing APE episodes were 74% lower (odds ratio: 0.26, 95% CI: 0.10–0.69) in patients from the post B-line implementation period compared with those from the pre-implementation period. Notably, adjusting for potential confounders did not affect the strength of this association, which remained statistically significant (p ≤ 0.030). Finally, dominance analysis indicated that the implementation of B-lines was the primary factor explaining the difference in APE episodes between the two periods, followed by dialysis duration and intra-dialysis weight gain. Conclusions: The systematic use of lung ultrasound (a simple, easy-to-learn, rapid and non-invasive method, easily performed at the patient’s bed) in everyday clinical practice was associated with a drastic reduction in episodes of APE in hemodialysis patients. Further observational and interventional studies are needed to confirm these results.

Centre-level fluid management practices in the BISTRO trial and their lack of association with participant fluid status and blood pressure in non-anuric haemodialysis patients.

Fluid assessment and management is a key aspect of good dialysis care and is affected by patient-level characteristics and potentially centre-level practices. In this secondary analysis of the BISTRO trial we wished to establish whether centre-level practices with the potential to affect fluid status were stable over the course of the trial and explore if they had any residual associations with participant's fluid status. Two surveys (S) of fluid management practices were conducted in 32 participating centres during the trial, (S1: 2017-18 and S2: 2021-22). Domains interrogated included: dialysate sodium concentration, (D-[Na+]), fluid and salt intake, residual kidney function, use of diuretics, incremental start, approaches to fluid assessment, management and dialysate temperature, (D-oC). Associations of these practices with the closeness of the participant's post-dialysis target weight to their normally hydrated weight, pre- and post-dialysis systolic (SBP) and diastolic blood pressure, (DBP), were analysed using intra-class correlations and multilevel modelling with adjustment for visit, age, sex and comorbidity burden. Variations in centre practices were reported but did not change during the trial, apart from some relaxation in salt and fluid restriction in S2. For our measures of fluid status, measured 2501 times in 439 non-anuric incident haemodialysis patients, centre-level intraclass correlations were extremely low, whereas patient-level correlations ranged between 0.12 and 0.47, strongest for pre- and post-dialysis-SBP, less so for post-dialysis-DBP. Multi-level analysis found no associations between D-[Na+], or assessment methods of fluid status. In S2, one centre, routinely using a D-Co of 35°C had more divergence between the target and normally hydrated weight, but this was not observed in S1, and no other associations were found. Centre-level fluid management practices were stable over the course of the BISTRO trial, and in contrast to patient-level factors, no centre-level associations were detected with fluid status or blood pressure. This may be because the trial imposed a standardised approach to fluid assessment in all trial participants who at least initially had residual kidney function, potentially over-riding the effects of other centre practices. Survey responses revealed substantial scope for developing and evaluating standardised protocols to optimise fluid management.

Association of uremic toxins and systemic inflammation with depression and anxiety among hemodialysis patients in Montenegro.

The purpose of this study was to examine the association between uremic toxins, inflammation, depression and anxiety among hemodialysis patients in Montenegro. The cross-sectional study included 88 patients undergoing hemodialysis. Depression and anxiety symptoms were assessed by Patient Health Questionnaire (PHQ-9) and Beck Anxiety Inventory (BAI). The standard laboratory methods were used to measure uremic toxins and systemic inflammation (C-reactive protein, Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR)). Clinically significant depression (PHQ-9 ≥ 10) and anxiety (BAI ≥16) were found in 55.7% and 27.2%, respectively. Logistic regression analyses revealed that serum urea, beta 2-microglobulin (B2M), and systemic inflammation (CRP, NLR, PLR) were significantly and independently associated with depressive symptoms, whereas serum urea, creatinine, uric acid, B2M, and systemic inflammation (CRP nad NLR) were associated with anxiety symptoms. Depressive symptoms and anxiety are common among hemodialysis patients in Montenegro, and are associated with increased levels of systematic inflammation, serum urea, and beta 2-microglobulin.

The Effect of Fordyce Happiness Training on Life Expectancy and Quality of Life in Hemodialysis Patients: An Intervention Study in Yazd, Iran

Background: Dialysis patients frequently experience issues such as fear, reduced social activity, and hopelessness due to lifestyle changes and treatment requirements. Objectives: This study aimed to determine the effect of Fordyce happiness training on quality of life and life expectancy in hemodialysis patients. Methods: This quasi-experimental intervention study involved 48 hemodialysis patients who were referred to Shahid Rahnemoun Hospital in Yazd, Iran, and selected through simple random sampling. Data collection tools included the Quality-of-Life Questionnaire for Kidney Patients (KDQOL-36) and the Miller Life Examination Questionnaire. Patients participated in ten 60-minute training sessions, held twice weekly. Data were collected at baseline and one month after the intervention and analyzed using SPSS 21 software. Results: Following Fordyce's happiness training, levels of potassium (K), creatinine (Cr), and blood urea nitrogen (BUN) in patients significantly decreased. Before the intervention, the mean scores for quality of life and life expectancy in dialysis patients were 51.9 ±28.27 and 169.75 ±11.95, respectively, which increased to 64.66 ±27.17 and 179.95 ±9.37 after the intervention. Paired t-test results indicated that Fordyce happiness training had a statistically significant positive effect on patients' quality of life (P &lt; 0.05) and life expectancy (P &lt; 0.05). Conclusions: The Fordyce happiness training program can improve quality of life and life expectancy in dialysis patients. In other words, happiness training may serve as a preventive strategy against mental disorders such as depression, anxiety, and life dissatisfaction in dialysis patients.

Does the hemodialysis program affect the prostate-specific antigen (PSA) serum levels in patients with end-stage renal disease (ESRD)? A cross-sectional descriptive study.

This study aims to investigate the effect of high-flux membrane hemodialysis on total prostate-specific antigen (tPSA) serum levels in hemodialysis patients and to evaluate the clinical significance of any observed changes. A cross-sectional descriptive study was conducted involving 75 hemodialysis patients at An-Najah National University Hospital. tPSA and hematocrit (Hct) serum levels were measured before and after one hemodialysis session. The correlation between changes in tPSA and Hct levels was analyzed using the Statistical Package for Social Sciences (SPSS). The mean age of the patients was 54.25 ± 15.27 years, with a mean hemodialysis duration of 40 ± 38 months. The mean tPSA levels before and after hemodialysis were 0.95 ± 0.81 ng/ml and 1.15 ± 0.96 ng/ml, respectively. Significant increases were observed in both tPSA (t = -3.264, p = 0.002) and Hct levels (t = -7.861, p < 0.001). The percentage changes in tPSA and Hct were 20% and 12%, respectively, with no significant correlation between the changes (r = 0.152, p = 0.215). Hemodialysis significantly elevates tPSA serum levels; however, no significant correlation was found between changes in tPSA and Hct. None of the patients showed clinically significant elevations in tPSA that would necessitate prostate biopsy. Therefore, high-flux membrane hemodialysis does not appear to compromise the diagnostic value of tPSA in hemodialysis patients.

Over-the-Wire Retrieval of Infectious Hemodialysis Catheter-Related Right Atrial Thrombus Causing Recurrent Pleural Empyema and Sepsis: A Case-Based Review

Introduction: Infectious catheter-related right atrial thrombus (CRAT) is a potentially fatal but often underestimated contingency associated with central venous catheter (CVC) in patients on hemodialysis. Management guidelines for CRAT are lacking, and its occurrence poses clinical challenges. Here, we describe the case of an infectious CRAT in a young patient on hemodialysis with peculiar clinical complications and perform a literature review. Case presentation and literature review: A 30-year-old man on hemodialysis after bilateral nephrectomy due to polycystic disease presented with hyperpyrexia resistant to broad-spectrum antibiotics. A pleural empyema caused by methicillin-resistant Staphylococcus aureus (MRSA) was diagnosed. Since fever persisted despite targeted antibiotic therapy, a transthoracic echocardiogram to exclude infective endocarditis was performed, showing a right atrial thrombus. CVC was promptly removed and the thrombus was aspirated through a percutaneous retrieval system. The thrombus cultural exam resulted positive for MRSA. After performing an extensive literature review, we could not find another case reporting the concomitance of these two rare complications. Conclusions: CRAT is a life-threatening complication in hemodialysis patients. While various treatment options exist, evidence-based guidelines are lacking, leading to individualized management strategies. Minimizing CVC use remains the best option for preventing such a complication.

Association of hypoalbuminemia with hospitalization and mortality in hemodialysis patients with COVID-19.

Hypoalbuminemia is associated with poor nutritional status and inflammatory response in infectious diseases. It is commonly observed in COVID-19 patients. The aim of this study is to assess the association of serum albumin with hospitalization and mortality in dialysis patients with COVID-19. We retrospectively collected 250 dialysis patients, with and without COVID-19. Demographic characteristics, clinical symptoms, and laboratory tests on admission or the confirmation of COVID-19 were collected. Univariate logistic regression model was used to evaluate the association of various factors with hospitalization and death in these patients. A total of 250 patients were included between December 1, 2022, and February 1, 2023, in our dialysis center. Among them, 218 were dialysis patients with COVID-19, and 32 were without COVID-19. Ten patients died due to COVID-19, and 8 patients had clinical data. In dialysis patients with COVID-19, a significant difference in serum albumin levels was observed between outpatients (37.28 ± 4.01 g/L) and hospitalized patients (33.42 ± 3.82 g/L), as well as between survivors (37.12 ± 4.07 g/L) and non-survivors (31.92 ± 2.52 g/L). Univariate logistic regression showed that the reduced albumin levels were associated with an increased risk of hospitalization and mortality in dialysis patients with COVID-19. Our study revealed that reduced serum albumin is associated with an increased risk of hospitalization and mortality in dialysis patients with COVID-19. Low serum albumin levels suggest a poor prognosis and nutritional support may improve clinical outcomes.

Beyond dialysis: Assessing therapeutic regimen compliance and sleep quality in chronic renal failure patients undergoing maintenance hemodialysis in Saudi Arabia.

Given its potential to impact physical and mental health, sleep quality is one of the most significant clinical outcomes among hemodialysis patients. Patients undergoing hemodialysis are required to adhere to an intricate treatment plan that consists of regular hemodialysis treatments, dietary and fluid restrictions, and a multi-drug regimen. Investigate the relationship between adherence to a therapeutic regimen and sleep quality among chronic renal failure patients undergoing maintenance hemodialysis. A descriptive correlational research design was followed. The study was conducted at the hemodialysis units in Hafr Albatin City, specifically at Hafr Albatin Central Hospital and King Khaled Hospital, Saudi Arabia. A convenience sample of 100 adult patients was selected for the study. The Hemodialysis Patients Adherence Questionnaire and Pittsburgh Sleep Quality Index were utilized to collect the data in 5 months from September 20, 2023 to February 15, 2024. The study revealed that more than half of the studied patients adhered to the therapeutic regimen, while (46%) did not adhere to it. More than half of the patients had poor sleep quality and were nonadherent to diet and fluid restrictions. Overall adherence score is negatively correlated with the global sleep quality score (r = -0.368, p < 0.001), indicating that poorer sleep quality is associated with lower overall adherence to the therapeutic regimen. While a significant proportion of the patients demonstrated adherence to overall therapeutic regimens, including dialysis sessions and medication intake, there was notable nonadherence to fluid and diet restrictions. Poor sleep quality, prevalent among two-thirds of the participants, correlates negatively with adherence to therapeutic regimens.

Platelet count has a U-shaped association with mortality in hemodialysis patients

Our previous manuscript showed that thrombocytopenia predicts all-cause mortality in Chinese hemodialysis (HD) patients. Based on the role of platelets in coagulation, clot formation, and systemic inflammation, we speculate that high platelets increase risk of thrombo-embolic events, hence the mortality. However, research evidence is currently lacking. Therefore, we utilized data from a very large international cohort study to explore the association of platelet counts with mortality and cardiovascular (CV) death in hemodialysis (HD) patients. International data from 396 facilities enrolled in the Dialysis Outcomes and Practice Patterns Study (DOPPS) phase 5 (2012–2015) were analyzed. Participants were divided into 3 groups according to their platelet counts (low: <100, normal: 100–300, high: >300*109). Associations between platelet counts and all-cause and CV mortality were analyzed using Cox regression, adjusted for confounders. There were 13,631 patients with median age of 65 years old. Males accounted for 61.2%. Mean platelet count was 205*109/L overall and ranged from 173 *109/L in China to 227 *109/L in Sweden. Overall, 2,348 (17.2%) patients died and 1017 (7.5%) died from CV disease. Both low (HR:1.48, 95% CI 1.21–1.80, p < 0.001) and high (HR:1.17, 95% CI 1.00- 1.35, p = 0.044) platelet counts were associated with higher all-cause mortality after adjustment for covariates; results for CV death were consistent. Platelet count has a U-shaped association with all-cause and CV mortality in HD patients, and thus may be used as an outcome predictor that is readily available among HD patients.

Analysis of the dynamics of transition from non-colonization to colonization and Staphylococcus aureus bacteremia in hemodialysis patients using Markov models.

Background Hemodialysis patients are frequently colonized by Staphylococcus aureus, leading to severe infections with high mortality rates. However, little is known about transition from non-colonization to colonization or bacteremia over time. The aim was to analyze the behavior of S. aureus colonization, identifying the probability of transition from non-colonized to colonized state or bacteremia, and the influence of specific covariates. Methods The study was conducted in a dialysis unit associated with a tertiary care hospital in Medellín between October 2017 and October 2019. An initial measurement was taken to evaluate S. aureus colonization, and follow-up measurements were performed 2 and 6 months later. Bacteremia evolution was monitored for 12 months. A two-state recurrent continuous-time Markov model was constructed to model transition dynamics from non-colonization to S. aureus colonization in hemodialysis patients. Subsequently, the model was applied to a third state of bacteremia. Results Of 178 patients on hemodialysis, 30.3% were colonized by S. aureus. Transition intensity from non-colonization to colonization was three times higher (0.21; CI: 0.14-0.29) than from colonization to non-colonization (0.07; CI: 0.05-0.11). The colonization risk increased in patients with previous infections (HR: 2.28; CI: 0.78-6.68), hospitalization (HR: 1.29; CI: 0.56-2.99) and antibiotics consumption (HR: 1.17; CI: 0.53-2.58). Mean non-colonized state duration was 10.9 months, while in the colonized state was 5.2 months. In the 3-state model, it was found that patients colonized were more likely to develop S. aureus infection (13.9%). Conclusion A more likely transition from non-colonization to colonization was found, which increases with factors such as previous infection. In addition, the development of bacteremia was more likely in colonized than in non-colonized patients. These results underline the importance of surveillance and proper management of S. aureus colonization to prevent serious complications, such as bacteremia, and improve prognosis in this vulnerable population.

Ultrasonographic Evaluation of Systemic Venous Congestion in Maintenance Hemodialysis Patients During Fluid Removal.

Fluid overload is a frequent and serious complication in hemodialysis patients. The combination of multiple point of care ultrasound (POCUS) measurements can identify significant venous congestion but its usefulness to determine ultrafiltration (UF) requirements and dry weight is unknown. Therefore, we evaluated prospectively patients in maintenance hemodialysis to establish the correlations between changes in venous congestion parameters and fluid removal. This was a prospective, single-center, observational study. POCUS venous congestion measurments were performed in 22 patients during 32 online post-dilutional hemodiafiltration sessions and findings were correlated with UF volume, central venous pressure and body water composition determined by multifrequency bioelectric impedance analysis (BIA). The pre dialysis weight was on average 1.9 kg above the BIA estimated dry weight, the average initial IVC diameter was <2 cm. An initial abnormal Hepatic Vein (HV) waveform was present in 26% (8) of the measurements. The average UF volume was 2084 ± 655 ml and correlated with changes in inferior vena cava (IVC) diameter (R= 0.34, CI 95% (0.18, 0.56) p < 0.05) but not with any other POCUS venous congestion parameters. Normalization of the IVC diameter and HV waveform was observed during the first UF hour in all initially altered measurements. Diameter reduction in the IVC correlated with total body water volume reduction estimated with BIA when measured immediately after fluid removal (R= 0.34, CI 95% (0.08, 0.56) p<0.05) Conclusion. Reduction in IVC diameter had a modest but significant correlation with UF volume in our patients on maintenance hemodiafiltration. POCUS may be used to monitor patients during UF.

Associations of Cognitive Function with Serum Magnesium and Phosphate in Hemodialysis Patients: A Cross-Sectional Analysis of the Osaka Dialysis Complication Study (ODCS)

Cognitive impairment and dementia are common in patients with chronic kidney disease, including those undergoing hemodialysis. Since magnesium and phosphate play important roles in brain function and aging, alterations in these and other factors related to bone mineral disorder (MBD) may contribute to low cognitive performance in patients on hemodialysis. This cross-sectional study examined the associations between cognitive function and MBD-related factors among 1207 patients on maintenance hemodialysis. Cognitive function was assessed by the Modified Mini-Mental State examination (3MS). The exposure variables of interest were serum magnesium, phosphate, calcium, calcium–phosphate product, intact parathyroid hormone, fetuin-A, T50 calciprotein crystallization test, use of phosphate binders, use of cinacalcet, and use of vitamin D receptor activators. Multivariable-adjusted linear regression models were used to examine the associations between 3MS and each of the exposure variables independent of 13 potential non-mineral confounders. We found that lower 3MS was associated with lower serum magnesium, lower phosphate, lower calcium–phosphate product, and nonuse of phosphate binders. These results suggest that magnesium and phosphate play potentially protective roles against cognitive impairment in this population.

Hepatitis B virus infection among hemodialysis patients in Aden-Yemen

HBV infection is one of major global health problems worldwide. It increases the morbidity and mortality rates among hemodialysis patients which make the management process more complicated. This study was aimed to determine the prevalence of HBV infection among hemodialysis patients and assessment the risk factors associated with infection. An analytical cross-sectional study was conducted on 50 HD patients. Blood samples were collected and serum HBsAg was analyzed using ELISA technique. The overall prevalence of HBV was 6 (12.0%). The males had highest rate. There were statistically significant recorded between the prevalence of HBV infection and age group 30 – 39 years and duration of hemodialysis from 1-2 years and more than 2 years (p=0.02, 0.001 and 0.001) respectively. It can be concluded that the HBV prevalent rate among HD patients was common and lower than that reported among most general population in Yemen. Increasing of the duration and long standing in hemodialysis unit may increase the risk of HBV infection. Hepatitis B vaccine should be given to all HBV negative HD patients before HD process and health education programs about the transmission routes of HBV and preventive measures should be implemented for general population.

Serum phosphate levels and mortality in incident hemodialysis patients: a national retrospective cohort study

Serum phosphate levels and mortality in incident hemodialysis patients: a national retrospective cohort study

Exercise and physical activity for people with chronic kidney disease: A national survey of nephrologist practice patterns in Saudi Arabia.

A variety of health benefits are associated with physical activity (PA) in individuals with chronic kidney disease (CKD). The aim of this study was to examine nephrologist practice patterns concerning exercise and PA in CKD patients. This is an online cross-sectional survey study that was conducted between June 2023 and May 2024 in Saudi Arabia. Nephrology fellow, specialists, and consultants in Saudi Arabia formed the study population. A total of 96 physicians participated in this study. Only 9.4% of renal units have exercise programs available to patients. These programs are available mainly for advanced CKD (pre-dialysis) and in-center hemodialysis patients. The major barriers for initiating or expanding exercise programs at their centers are a lack of motivation/interest from front-line staff (55.2%), lack of interest from management (48.3%), and no funding (47.1). Around 56.2% of respondents ask patients about their level of PA. Additionally, 64.6% give patients specific advice on how to increase their level of PA. For the types of exercise most beneficial for people with CKD, 90.6% recommend walking. Around 34.4% of respondents believe that physiotherapists should take ownership in providing exercise counseling and resources to people with CKD. The majority agreed or strongly agreed to recommend exercise in patients with CKD (76.0%). The mean attitude score for the study participants was 32.1 (standard deviation: 3.9) out of 40 (equal to 80.3%); which demonstrates positive attitude towards recommending exercise for CKD patients. Binary logistic regression analysis identified that there is no statistically significant difference between physicians in term of their attitude towards recommending exercise for CKD patients (P > .05). This study highlights a critical gap in the availability of exercise programs for CKD patients. Key barriers include lack of interest by staff and management and funding issues. In spite of these barriers, a majority of physicians acknowledge the role of exercise in CKD patients and advice regarding PA on a frequent basis. It suggests recommendations in order to expand the programs, including increasing staff motivation, securing management support, and getting funding for exercise programs and identifying the role of physiotherapists in exercise counseling for CKD patients.

Validity and Reliability of the Korean Version of the Caregiver Burden Questionnaire for Family Caregivers of Hemodialysis Patients

AimThis study aimed to adapt and validate the Korean version of the Caregiver Burden Questionnaire for Family Caregivers of Hemodialysis Patients, originally developed by Hejazi et al. in 2022, to ensure its applicability and validity in Korea. MethodsUsing both online and offline approaches, this study included 230 family caregivers. Data analysis was performed with SPSS AMOS version 29.0 using the Korean version of the Caregiver Burden Questionnaire for Family Caregivers of Hemodialysis Patients and the Korean version of the Zarit Burden Interview as the primary instruments. ResultsThe findings confirmed the high content validity of the questionnaire (scale-level content validity index = .99), and confirmatory factor analysis established its construct validity. Convergent validity was confirmed with average variance extracted values ranging from .43 to .87, and composite reliability scores ranging from .80 to .91. A significant positive correlation with the Korean version of the Zarit Burden Interview (r = .81) demonstrated concurrent validity. The tool consists of 21 items across four factors on a 5-point Likert scale, exhibiting excellent internal consistency (Cronbach's α = .91) and good test-retest reliability (intraclass correlation coefficient = .79). ConclusionsThis study validated a reliable instrument for assessing caregiver burden in families of hemodialysis patients in Korea. This tool accurately measures caregiver challenges and has the potential to enhance societal health and welfare.

The Effect of Application-Based Exergames on Cognitive Function in Hemodialysis Patients

Aims: Hemodialysis (HD) patients may disrupt physical and cognitive capabilities, affecting older mobility, independence, psychological well-being, and health care expenditures. Home-based exergame training overcomes accessibility issues. Methods: This research examined how mobile app exergames affected cognitive performance in hemodialysis patients. This research used a repeated measurement-quasi-experiment two-group pretest-posttest design in a West Java. The intervention group trained three times a week for 30-40 minutes for two months, totaling 24 sessions (8 weeks). In the control group, participants were told to live normally. Results: Inlcusion criteria was performing HD at least twice a week, age &gt; 65, living independently, self-reported health, ability to stand for 10 minutes without help, and access to a TV with HDMI connection. The Trail Making Test (TMT) measured psychomotor speed and executive function. ANCOVA was used to compare scores before and after the intervention in both groups. The repeated ANOVA test revealed that the trial making test A (TMT A) decreased significantly in the intervention group after one month intervention (T2) (from 79.77 ± 7.23 at baseline to 40.87 ± 5.33 at follow up), with the effect size was 0.41, indicating moderate effect size. The trial making test B (TMT B) decreased significantly in the intervention group after one month intervention (T2) (from 77.6 ± 24.2 at baseline to 70.32 ± 23.3 at follow up), with the effect size was 0.45, indicating moderate effect size. However, there was not significant change of Trial making Test A and B from baseline to follow up time in the control group. Conclusions: Findings of this study could be one of the new solutions to help patients undergoing hemodialysis improve their cognitive function. Exergame training may be done at home, which helps to overcome accessibility constraints.

Factors Affecting the Quality of Life of Patients with Chronic Renal Failure Undergoing Hemodialysis at RSUD Sekarwangi Sukabumi District

Aims: Chronic renal failure is an increasingly prevalent global health issue, with hemodialysis as the most common treatment method. Factors affecting patients' quality of life include age, gender, education, occupation, and treatment duration. This study aimed to identify and examine these factors. Methods: This cross-sectional study involved 80 hemodialysis patients at RSUD Sekarwangi Kabupaten Sukabumi, using total sampling and questionnaires for data collection. Logistic regression was used for data analysis, and the study received ethical approval. Results: The Chi-square test results indicate that age, gender, education, occupation, duration of chronic kidney failure, and length of hemodialysis significantly influence the quality of life in chronic kidney failure patients (p &lt; 0.005). Logistic regression analysis identified education as the dominant factor impacting quality of life (OR = 39.316). Conclusion: The study reveals that age, gender, education, occupation, duration of chronic renal failure, and length of hemodialysis treatment significantly impact the quality of life of patients with chronic renal failure.
