Background/Objectives: Arteriovenous (AV) graft is a procedure for hemodialysis performed in the arm. Optimizing AV graft design is vital to enhance haemodialytic efficiency in patients with kidney disease. Despite being a standard procedure, making it work optimally is still difficult due to various graft diameters and anastomosis configurations, which have limited studies. This research aims to find the ideal AV graft tube diameter on blood flow and pressure gradients and the ideal body site for AV graft implantation and to study their angles for dialysate flow. Methods: Nine models were designed in Autodesk Fusion 360 with 40°, 50°, and 60° angles each having 2 mm, 5.1 mm, and 14.5 mm diameters, all following specific equations on continuity, momentum (Navier-Stokes Equation)), and the Reynolds Stress Model (RSM). The CFD simulation of these models was performed in ANSYS Fluent with an established parameter of 0.3 m/s inlet velocity and stiff/no-slip graft and artery wall boundary condition. Results: As a result, the design with a diameter of 14.5 mm and a 40° angle was overall the most ideal in terms of minimal wall shear stress and turbulence. Conclusions: Thus the brachiocephalic area or the forearm is calculated to be the most optimal implantation site. Additionally, varying angles do affect dialysate flow, as smaller values cause less stress.

This study explores the feasibility, safety, and efficacy of percutaneous transluminal angioplasty (PTA) for reinserting tunneled cuffed catheters (TCC) with a Dacron sheath in the right internal jugular vein (RIJV) in hemodialysis patients with a history of prior RIJV catheterization and subsequent stenosis or occlusion of the RIJV, right innominate vein, and superior vena cava. Clinical data from 21 hemodialysis patients with dysfunctional vascular access who underwent PTA for reinsertion of TCC in the RIJVs from July 2020 to June 2023 at the First and Second Affiliated Hospitals of Bengbu Medical College were retrospectively analyzed. Clinical efficacy during hospitalization, postoperative TCC blood flow, and related complications during follow-up were observed. The procedure was successful in all 21 patients, with postoperative TCC blood flow meeting daily hemodialysis requirements. Only one case experienced acute bleeding with contrast agent extravasation at the intersection of the left and right innominate veins during sharp recanalization. No severe complications, such as arrhythmias, vascular rupture, pneumothorax, mediastinal hematoma, or pericardial tamponade, occurred during the procedures. Upon discharge, all patients exhibited satisfactory TCC blood flow (247.14 ± 11.46 ml/min). Postoperatively, TCC blood flow ranged between 200 and 260 ml/min, meeting the demands of regular hemodialysis. For patients with a history of repeated TCC or non-tunneled catheter (NTC) placement in the RIJV, reinserting TCC in the RIJVs through PTA is a safe and reliable technique. It effectively utilizes vascular resources and prevents vascular resource depletion associated with changing the venous catheter placement location., (© 2024. The Author(s).)

Objective: To compare the effects of warm and cold dialysate solutions on the duration of post-dialysis fatigue in patients undergoing maintenance haemodialysis., Methods: The quasi-experimental study was conducted at the Department of Nephrology, Pak Emirates Military Hospital, Rawalpindi, Pakistan, from May 9 to September 10, 2023, and comprised adult patients of either gender undergoing maintenance haemodialysis for a minimum of 3 months. The patient initially underwent haemodialysis with a dialysate temperature of 36°C for 2 weeks. During the subsequent washout period of one week when the dialysate temperature was not monitored, they underwent haemodialysis with a dialysate temperature of 37°C for another 2 weeks. Blood pressure was monitored every 30 minutes to record any hypotensive episodes. Patients were asked if they felt fatigued after the last haemodialysis session, and the duration was noted down. Data was analysed using SPSS 24., Results: Of the 92 patients with mean age 49.1±16.1 years, 57(62%) were males. Post-dialysis fatigue was seen in 67(72.8%) and 75(81.5%) patients with dialysate temperatures at 36°C and 37°C, respectively (p<0.001). The duration of post-dialysis fatigue was also significantly longer at dialysate temperatures 37°C p<0.001). There was no significant difference in the proportion of hypotensive episodes in the two groups (p=0.445)., Conclusion: Dialysate temperature 36°C was found to be associated with less frequent and shorter duration of postdialysis fatigue compared to dialysate temperature 37°C.

Unfractionated heparin is the most used anticoagulative agent for extracorporeal settings in children, including acute hemodialysis modalities. In certain situations, such as heparin-induced thrombocytopenia, alternatives must be applied. The direct thrombin inhibitor bivalirudin has come forth as an attractive substitute. Bivalirudin is currently only approved for adult use in specific percutaneous coronary intervention settings. However, it has a growing off-label popularity in different contexts for both adult and pediatric patients. Experience with bivalirudin in children is mainly limited to extracorporeal membrane oxygenation, ventricular assist devices and during cardiopulmonary bypass surgery. Literature about its use as anticoagulation strategy for pediatric hemodialysis is very scarce. Here, we present two pediatric cases where bivalirudin was used during acute hemodialysis, followed by a short summary of recent literature., (© 2024 International Society for Hemodialysis.)

Acute kidney injury (AKI) requiring dialysis (AKI-D) is an important health care burden and is associated with very high in-hospital mortality. Timely initiation of dialysis in AKI is fundamental to achieve treatment goals and to provide solute clearance and removal of excess fluid while awaiting the recovery of kidney function. The primary outcome of interest of the study was recovery of sufficient kidney function to discontinue haemodialysis therapy and complete recovery of renal function. This prospective observational study has been conducted in Mymensingh Medical College Hospital, Bangladesh from September 2019 to February 2021. All adult patients with AKI-D were included in the study. All patients were followed up till death or complete recovery or for a maximum period of six month. A total of 134 patients of AKI-D were included in the study with the mean age of 42.3±15.7 years. Male (54.5%) were slightly more than female with a male to female ratio of 1.2:1. Diabetes and hypertension were present in 16 (11.9%) and 47 (35.1%) patients respectively. The causes of AKI were sepsis (35.1%), urinary tract infection (34.3%), acute watery diarrhoea (9.7%), leptospirosis (11.2%), obstetric (10.4%), malignancy (8.2%), post renal obstruction (8.2%), drugs (7.5%), surgery (18.7%), rapidly progressive glomerulonephritis (6%), COVID 19 (5.2%), rhabdomyolysis (4.5%), intestinal obstruction (3.7%), acute gastroenteritis (2.2%), wasp bite (2.2%), insecticide poisoning (1.5%), star fruit toxicity (1.5%), haemolytic uremic syndrome (0.7%) and unknown (1.5%). Mean number of dialysis requirement was 5.9±8.6 and length of hospital stay was 15.4±10.5 days. Out of 134 patients, 95(70.9%) were discharged from hospital and 39(29.1%) died in hospital. Total death of patients during the study period were 49(36.6%) including home death of 10(7.5%) patients. Complete recovery of kidney function was achieved in 70(52.2%) patients and partial recoveries of kidney function who can survive without dialysis were observed in 12(9%) patients. Three (2.2%) patients remain on dialysis and 85(63.4%) patients survived during the study period. Survival rate was significantly higher in patients with ≤40 years (72.6%) and significantly lower in patients with malignancy (18.2%) and post renal obstruction (27.3%). Outcomes of patients with AKI-D remain poor. Advanced stage of AKI, older age, late presentation, malignancy, nutritional deficiency and delay at initiation of dialysis were associated with high mortality and reduced survival.

We present a 60-year-old maintenance hemodialysis patient who initially presented with neck swelling, which was diagnosed as a thyroid issue. Following a hemodialysis session, the swelling in the neck progressively enlarged, leading to respiratory distress and eventual cardiac arrest. During a life-saving tracheotomy, dark red blood was observed, and endotracheal intubation was urgently performed. Subsequent computed tomography examination identified multiple areas of slight high-density images in the nasopharyngeal cavity, oropharyngeal cavity, and esophagus. As time passed, the patient's hematoma underwent spontaneous absorption, but signs of recovery were absent. We discuss the rarity, etiology, diagnosis, and management of spontaneous neck hematoma in maintenance hemodialysis patients., (© 2024 The Author(s).

This commentary delves into the complexities surrounding chronic kidney disease management in Pakistan, specifically examining the critical role played by renal satellite units in providing accessible dialysis services. Chronic kidney disease in Pakistan accounts for 3.9% of total deaths, warranting a focused exploration of challenges and potential solutions. RSUs, smaller entities affiliated with main renal units, emerge as key players in addressing issues of geographic accessibility and diminishing travel burdens for chronic kidney disease patients. Challenges such as financial constraints, limited resources, and staff shortages, particularly in rural settings, pose significant hurdles to the effective functioning of RSUs. This commentary emphasizes the importance of clear eligibility criteria, robust vascular access support, regular physician engagement, and the strategic integration of telemedicine. It explores diverse funding models, including government allocations, community contributions, and philanthropic partnerships, as potential solutions to alleviate cost-related concerns. The commentary advocates for a holistic, cost-effective approach to chronic kidney disease care, highlighting the transformative potential of renal satellite units in improving health outcomes across varied settings., (© 2024 International Society for Hemodialysis.)

Aims: To determine the effect of virtual reality glasses intervention on pain, vital signs, and patient satisfaction of hemodialysis patients undergoing AVF catheter puncture., Design: Randomized controlled study., Methods: The study was conducted in 60 patients receiving dialysis treatment in the HD unit of a public hospital in Turkey. The data were collected via the "Patient Identification Form", "Visual Analog Scale/VAS" and "Hemodynamics Variables Inspection Form". The patients in the experiment group watched videos through the virtual reality glasses for totally 5 minutes in average, 2 minutes before the AVF cannulation process and 3 minutes during the process. No intervention was applied to the patients in the control group other than the normal nursing interventions in the HD unit., Results: In the intra-group comparisons, the 2nd and 3rd measurement average pain level scores of the patients with in the experimental group were determined to be statistically significantly lower compared to their 1st measurement (p < 0.05); the 3rd measurement average pain level scores of the control group were determined to be statistically significantly lower compared to their 1st and 2nd measurements (p < 0.05)., Conclusions: It was determined that the virtual reality glasses decreased the pain that emerges during the AVF cannulation process and increased the patient satisfaction level. It is suggested that the virtual reality glasses should be used by the nurses in the HD unit since it is easily applicable in coping with pain in the patients and since it is an invasive method., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: Leg muscle cramps and compromised sleep patterns are prevalent issues experienced by individuals undergoing hemodialysis treatment. The aim of this study was to assess the impact of massage therapy on hemodialysis patients experiencing cramping, specifically focusing on the frequency and severity of cramps, as well as the quality of sleep., Methods: This research involved 36 hemodialysis patients. The intervention group received intradialytic massage targeting the lower extremities, administered three times a week for a total of six sessions over a 2-week period. Data collection utilized a Patient Information Form, the Pittsburgh Sleep Quality Index, the Visual Analog Scale, and a Patient Follow-Up Form., Findings: The study revealed a significant reduction in both the frequency and severity of cramps experienced by patients in the intervention group during hemodialysis sessions and at home, from the end of one session to the beginning of the next, compared to the control group (p < 0.05). This effect was observed over the course of six dialysis sessions. Additionally, there was a notable decrease in the mean total score of the Pittsburgh Sleep Quality Index (PSQI) among participants in the intervention group, declining from 9.00 ± 3.79 prior to massage therapy to 5.94 ± 2.84 post-massage (p < 0.001). Conversely, no significant change was observed in the control group, highlighting a notable disparity between the intervention and control groups in terms of sleep quality improvement., Discussion: The investigation revealed that employing intradialytic massage on the lower extremities led to a reduction in both the frequency and severity of cramps, while also eliciting a positive impact on the sleep quality of patients undergoing hemodialysis., (© 2024 International Society for Hemodialysis.)

Introduction: Optimization of ultrafiltration during hemodialysis is a critical parameter in achieving therapeutic efficacy and ensuring hemodynamic stability. While various modalities such as blood volume monitoring, inferior vena cava diameter assessment, natriuretic peptide levels, bioimpedance assay, and lung ultrasound have been widely explored in the context of maintenance hemodialysis, the concept of volume-guided ultrafiltration in dialysis patients with acute kidney injury remains unexplored., Methods: Adult patients with acute kidney injury requiring dialysis, who were hemodynamically stable and not on ventilator support, without underlying lung pathology or cardiac failure, were randomized into two groups. All patients underwent 28-zone lung ultrasound before dialysis. The ultrafiltration was decided based on the treating physician's clinical judgment in controls. In the intervention group, the ultrafiltration orders prescribed by the treating physician were modified, based on the Kerley B line scores obtained by lung ultrasound. The rest of the dialysis prescriptions were similar. A postdialysis lung ultrasound was done in both groups to assess the postdialysis volume status 30 min after the dialysis session., Results: A total of 74 patients undergoing hemodialysis for acute kidney injury were randomized. The baseline characteristics were comparable except for higher baseline B line score scores in the intervention arm. All patients received similar dialysis prescriptions. The lung ultrasound-guided ultrafiltration arm had a higher change in B line scores (BLS) from baseline (4 [0-9.5] vs. 0 [0-4]; p value 0.004) during the first dialysis session. The predialysis BLS indexed to ultrafiltration (mL/kbw/h) were significantly lower in controls, reflecting a relatively higher rate of ultrafiltration in controls compared with intervention (p = 0.006). The total number of dialysis sessions done in the control and intervention arm were 61 and 59, respectively. Among controls, 23/61 sessions (37.7%) had intradialytic adverse events, whereas, in the intervention arm, only 4/59 sessions (6.7) had any adverse intradialytic events (p < 0.01)., Conclusion: Lung ultrasound-guided ultrafiltration was associated with a better safety profile, as demonstrated by reduced intradialytic events., (© 2024 International Society for Hemodialysis.)

Few studies have reported the application of vacuum-sealing drainage of infected dialysis vascular access wounds. Herein, we present a case of buttonhole-related arteriovenous fistula infection treated with vacuum-sealing drainage. A 53-year-old female hemodialysis patient was hospitalized with an inflamed arteriovenous fistula. The patient underwent non-tunneled catheterization for dialysis and was treated with moxifloxacin and vancomycin for staphylococcal infection. On Day 3, the skin overlying the inflamed fistula was ulcerated, resulting in severe hemorrhage. Emergency surgery was performed along with vacuum-sealing drainage for fistula reconstruction. Vacuum-sealing drainage accelerated the recovery of the wound without complications. No further access complications occurred during over a 3-year follow-up., (© 2024 International Society for Hemodialysis.)

Introduction: This study aimed to compare the prevalence of potentially inappropriately prescribed drugs in hemodialysis patients and patients with chronic kidney disease who did not require renal replacement therapy, as well as to identify risk factors associated with potentially inappropriate prescribing., Methods: The study was designed as a cross-sectional study conducted at the Department of Nephrology, Clinical Center in Nis, Serbia. The patients were divided into two groups: (1) patients on hemodialysis treatment and (2) patients with various degrees of chronic kidney disease without renal replacement therapy. The presence or absence of potentially inappropriate prescribing was determined using the 2015 AGS Beers criteria., Findings: The study included a total of 218 patients aged 65 years and over. The number of patients with potentially inappropriate prescribed drugs did not differ significantly (chi-square = 0.000, p = 1.000) between patients on hemodialysis (27 of 83, i.e., 32.5%) and patients with various degrees of chronic kidney disease without renal replacement therapy (44 of 135, i.e., 32.6%). Factors associated with potentially inappropriate prescribing in hemodialysis patients were the number of drugs (hazard ratio [HR] = 1.919, 95% confidence interval [CI]: 1.325-2.780) and number of comorbidities (HR = 1.743, 95% CI: 1.109-2.740). The number of drugs (HR = 1.438, 95% CI: 1.191-1.736) was the only independent factor associated with increased risk of potentially inappropriate prescribing in patients without renal replacement therapy., Discussion: Our study showed that potentially inappropriate prescribing is a relatively frequent phenomenon present in about a third of patients in both study groups. The number of prescribed drugs was the main factor associated with the increased risk of potentially inappropriate prescribing in both groups., (© 2024 International Society for Hemodialysis.)

Depletion of veins for dialysis access is a challenging life threatening situation for patients in need of haemodialysis. The utilisation of intracardiac catheter is a rare procedure with scarce reported experience. We describe the case of a 68-year-old male that contributes to the limited knowledge of performing a life-saving intracardiac catheter placement for emergency haemodialysis in a patient without immediate alternative renal replacement therapy available. We also retrospectively analyse the experience reported so far and summarise complications and outcomes. In our case, the patient was able to pursue haemodialysis after intracardiac catheter placement without any complications. Two weeks later, the patient successfully received a kidney transplant from a deceased donor and has a serum creatinine of 1.7 mg/dL after 2 years of follow-up. There are only four reported cases of kidney transplantation after the procedure, including our own. Intracardiac catheter is an emerging option that could be considered in certain patients as the last resort. Further investigation with regards to patient candidacy and procedure security are necessary., (© 2024 Asian Pacific Society of Nephrology.)

Introduction: The aim of this study was to investigate changes in echocardiographic right ventricular (RV) indices in relation to the degree of fluid accumulation between hemodialysis sessions, evaluated according to the recommended threshold of interdialytic-weight-gain corrected for dry weight (IDWG%)., Methods: A post-hoc analysis was performed using data from 41 maintenance hemodialysis patients. Patients were divided into a higher (>4.5%) and a lower (<4.5%) IDWG% group and underwent an echocardiographic assessment at the start and the end of the 3-day and the 2-day interdialytic interval., Results: RV systolic pressure (RVSP) increments were more pronounced in the higher compared to the lower IDWG% group (16.43 ± 5.37 vs. 14.11 ± 13.38 mm Hg respectively, p = 0.015) over the 3-day interval, while changes in RV filling pressures, did not differ significantly between the groups (p = 0.84)., Conclusions: During the 3-day interdialytic interval, pulmonary circulation is particularly overloaded in patients with fluid accumulation higher than the recommended thresholds, as evidenced by higher RVSP elevations., (© 2024 International Society for Apheresis and Japanese Society for Apheresis.)

Background: Missed medication doses are a common and often preventable medication-related error that have been associated with an increased length of stay and mortality. Hemodialysis is a common, relatively predictable reason that patients are unavailable, resulting in missed doses., Objective: To evaluate the implications of a pharmacist-led intervention to standardize the medication administration times for patients requiring hemodialysis who were prescribed antihypertensives, antiepileptics, apixaban, and/or antimicrobials., Methods: A retrospective preanalysis and postanalysis of a pharmacist-led intervention were performed at a single-center, safety net hospital. Patients receiving dialysis and prescribed one of the targeted medications were included. The primary endpoint was the composite of missed and delayed doses., Results: A total of 25 patients receiving 126 dialysis sessions in the preintervention group and 29 patients receiving 80 dialysis sessions in the postintervention group were included for analysis. For the primary endpoint, 118 (18%) versus 57 (9.3%) doses were missed or delayed in the preintervention versus postintervention group, respectively ( P < 0.001). The primary endpoint was driven by fewer delayed doses in the postgroup. The number of antimicrobials given on a correct schedule increased in the postintervention group (98.3% vs 99.1%, P = 0.044)., Conclusion and Relevance: A pharmacist-led intervention for standard medication administration times in patients requiring hemodialysis increased the number of prescribed medication doses given and given on time. The intervention also led to more antimicrobials administered at appropriate times relative to dialysis sessions., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The rate and the duration of ultrafiltration (UF) are considered the most important factors to affect vascular refilling. The aim of the study was to investigate whether a UF profile could improve the vascular refilling., Methods: Dialysis was delivered by a machine providing feedback control of ultrafiltration rates. Absolute blood volume (BV) was measured by dialysate bolus method. Vascular refilling volume ( V ref ) was calculated as UF volume - Δ absolute BV., Results: In 40 patients, refilling fraction ( V ref /UF volume) was 30.5% in the first hour. Thereafter, refilling fraction steeply increased and reached maximum values in the third and fourth hour at about 95%. The cumulative refilling fraction was 68.5 ± 9.4% at the end. In 14 patients, refilling data from the feedback-controlled UF profile were compared to dialysis sessions with constant UF rates. In 12 of 14 patients, refilling fraction was significantly ( p  = 0.013) higher in sessions with UF profile (71.6% vs 64.4%).There was a significant negative correlation ( r  = -0.606; p  = 0.002) between the blood volume to extracellular volume ratio and the refilling fraction. The sum of this ratio and the refilling fraction was 1.01 ± 0.06., Conclusions: Despite significant differences, a feedback-controlled UF profile has no advantage over the previous refilling studies with regard to the refilling fraction because vascular refilling seems to depend mainly on the ratio of BV to ECV. This would explain the different results in studies using BV guided UF feedback programs., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: We aimed to evaluate the relationship between carotid intima-media thickness (CIMT), which is a known indicator of cardiovascular risk and atherosclerosis, and uric acid level, which may be an easy marker for cardiovascular diseases due to its antioxidant and pro-oxidant properties in hemodialysis patients., Methods: In this cross-sectional study, we evaluated 77 hemodialysis patients. The mean CIMT of these patients was measured and recorded by Doppler ultrasonography. Patients were divided into two groups according to their serum uric acid levels. Correlation analysis and linear regression analysis were used to define the relationship between study parameters., Findings: The mean CIMT levels in the normouricemic group and the hyperuricemic group were 0.95 ± 0.15 and 1.07 ± 0.15, respectively. There was a statistically significant difference between the two groups (p = 0.001). There was a statistically significant and moderate linear correlation between serum uric acid level and mean CIMT (r = 0.402; p = 0.002). Univariate and multivariate linear regression analyses were performed to identify variables that could independently affect the mean CIMT value. According to analysis, uric acid (p < 0.001), hypertension (p = 0.008), albumin (p = 0.029), and C-reactive protein (p = 0.042) were found independent risk factors for mean CIMT value., Discussion: We found a significant relationship between serum uric acid level and CIMT, which indicates carotid atherosclerosis. Serum uric acid level is a low-cost laboratory parameter that can be measured in almost all laboratories, and it may be valuable in the hemodialysis patient group to identify patients at high risk of carotid atherosclerosis., (© 2024 International Society for Hemodialysis.)

Introduction: The objective of the current study was to investigate the association between lower body bone fractures occurring during maintenance hemodialysis and prognosis., Methods: This study included 151 hemodialysis patients at the dialysis center of our hospital as of December 2017, and data were systematically gathered from medical records over a period of 5 years, concluding in December 2022., Results: Fourteen patients, 3.0 per 100 person-years, in 151 hemodialysis patients suffered from lower body bone fractures. The ratio of males was significantly lower, and age was significantly higher in the lower body bone fracture group than in the no lower body bone fracture group. Duration of hemodialysis prior to entry into this study was significantly shorter in the lower body bone fracture group than in the no lower body bone fracture group. Serum albumin was significantly lower and alkaline phosphatase was significantly higher in the lower body bone fracture group than in the no lower body bone fracture group. Mortality rate was significantly higher in the lower body bone fracture group (85.7%) compared to no lower body bone fracture group (28.5%) (p = 0.01). Kaplan-Meier survival curves for mortality showed that lower body bone fracture group had poor prognosis compared to no lower body bone fracture group. Multivariable-adjusted odds ratio for mortality were significantly higher for cases with lower body bone fractures., Conclusion: Lower body bone fractures have high mortality rates and poor prognosis in the patients with hemodialysis., (© 2024 International Society for Apheresis and Japanese Society for Apheresis.)

Introduction: Prior observational studies conducted in the hemodialysis population have suggested a reverse association between dialysis-unit blood pressure (BP) and mortality. The present study aimed to investigate the prognostic association of home versus dialysis-unit BP with all-cause mortality in hemodialysis patients., Methods: At baseline, 146 patients receiving maintenance hemodialysis underwent assessment of their BP with the following methods: (i) 2-week averaged routine predialysis and postdialysis BP measurements; (ii) home BP monitoring for 1 week that included duplicate morning and evening BP measurements with the use of validated devices., Results: Over a median follow-up period of 38 months (interquartile range [IQR]: 22-54), 44 patients (31.1%) died. In Kaplan-Meier curves, predialysis and postdialysis systolic BP (SBP) was not associated with all-cause mortality, while home SBP appeared to be of prognostic significance (log rank p = 0.029). After stratifying patients into quartiles, all-cause mortality was lowest when home SBP was ranging from 128.1 to 136.8 mmHg (quartile 2). In univariate Cox regression analysis, using quartile 2 as a referent category, the risk of all-cause mortality was 3.32-fold higher in quartile 1, 1.53-fold higher in quartile 3 and 3.25-fold higher in quartile 4. The risk-association remained unchanged after adjustment for several confounding factors (adjusted hazard ratio: 4.79, 1.79, 3.63 for quartiles 1, 3, and 4 of home systolic BP, respectively)., Conclusion: Our findings suggest that among hemodialysis patients, 1-week averaged home SBP is independently associated with all-cause mortality. In sharp contrast, SBP recorded either before or after dialysis over 2 weeks is not prognostically informative., (© 2024 The Authors.

Background: Comprehensive, patient-specific models are essential to study calcium deposition and mobilization during dialysis. We aim to develop tools to support clinical prescriptions with a more accurate approach for the prediction of calcium mobilization while also considering major electrolytes and catabolites., Methods: We modified a multi-solute model predicting patient-specific dialysis response by incorporating a calcium buffer to represent bone exchanges. Data from four centers, involving 127 patients with six sessions each, were utilized. For each patient, three sessions were allocated for model training (ID 123 ), while the remaining sessions were for validation (PRED456). The normalized root mean square error (nRMSE%) was used to evaluate both descriptive and predictive accuracy. Correlations between initial data and calcium exchanges were also assessed., Results: The overall nRMSE% for ID 123 was 3.92%. For PRED 456 , it was 3.46% (ranging from a minimum of 1.17% for [Na + ] to a maximum of 6.62% for [urea]). The median nRMSE% for plasma calcium varied between 1.13 and 8.32 for SHD sessions, depending on whether Ca&#95;dialysis fluid (Ca d ) was ≥ or <1.50 mmol/L, respectively. For HDF sessions, the range was between 2.90 and 5.89. A significant and moderate correlation was found between overall calcium removal and the buffer balance. The most robust correlation observed was between the amount of calcium administered via post-dilution fluid and the overall calcium removal in the dialysis filter., Conclusions: Identical therapy settings do not uniformly affect calcium mobilization, and our approach offers insight into calcium distribution across body compartments. This understanding will enhance clinical prescription practices., (© 2024 International Center for Artificial Organ and Transplantation (ICAOT) and Wiley Periodicals LLC.)

Introduction: Gabapentin is an antiepileptic drug that alleviates neuropathic pain. Its oral use reduces the intensity of pruritus in patients receiving chronic dialysis therapy. However, it could lead to toxicity because of the patients' renal deficiency. In this study, we assessed the use of gabapentin topical in treating pruritus in dialysis patients., Methods: This randomized, triple-blinded trial was performed on 80 patients divided into two groups randomly (40 in each group). In intervention group, 92.5% of the patients were on hemodialysis. Patients in intervention and control groups were provided with 5% gabapentin and placebo topical creams every 2 weeks for a month. Both Visual Analog Scale and 12-item Pruritus Severity Score questionnaire were used to evaluate itching intensity and score before treatment, a month, and 2 months after starting treatment in both groups. In addition, the effect of itching on quality of life was investigated with the same questionnaire., Findings: Eighty patients (40 in each group) participated in our study. No complication was found in our intervention group. Itching score significantly decreased after a month and 2 months of follow-up in intervention group (p < 0.001)., Discussion: Our results showed that 5% gabapentin topical cream can be effective in reducing itching in different areas of the body. None of our patients reported complications., (© 2024 International Society for Hemodialysis.)

A 61-year-old female with diabetes and stage 5 chronic kidney disease on hemodialysis since 3 years via left brachiocephalic arteriovenous fistula presented with uncontrolled sugars, weight loss, and dysphagia. On evaluation, she was found to have an oral thrush with leucocytosis. Initial blood and urine cultures were sterile, and ultrasonography revealed hypoechoic lesions in the left lobe of the liver. She had high-grade fever followed by seizures on postadmission Day 10. Brain imaging and serum electrolytes were normal. Cerebrospinal fluid analysis was noncontributory, and urine culture revealed Candida non-albicans with elevated white blood cell counts. She was started on fluconazole; however, her clinical condition deteriorated, with hemodynamic instability. Repeat abdominal computerized tomography revealed increasing hypodense lesions in the left lobe of the liver with elevated beta D glucan levels. Percutaneous drainage of the abscess revealed no fungal elements. In view of clinical deterioration, amphotericin B was started, which resulted in clinical improvement. Clinician should have high index of suspicion for fungal etiology in hemodialysis patients presenting with liver abscess., (© 2024 International Society for Hemodialysis.)

Aims/Background Chronic renal failure (CRF) is the eventual outcome shared by various progressive renal diseases, posing a serious threat to the physical health of patients. CRF patients are required to undergo hemodialysis (HD), which imposes heavy psychological and mental burdens for most individuals. This study explores the effects of Internet Plus-based continuous nursing on the compliance of CRF patients with HD. Methods This study retrospectively analyzed the clinical data of 160 CRF patients undergoing HD in the Yantai Yuhuangding Hospital from March 2021 to April 2023, after excluding eight cases from an originally selected cohort of 168 cases. These patients were divided into two groups: 79 cases who received the routine nursing from March 2021 to March 2022 were categorized as the routine group, whereas 81 cases who were given Internet Plus-based continuous nursing from April 2022 to April 2023 were assigned into the observation group. The treatment adherence, self-management behaviors, quality of life and incidence of HD complications were compared in both groups. Results Both groups demonstrated no significant difference in the baseline information ( p > 0.05). The scores of adherence in terms of HD attendance, medications, fluid restrictions and diet recommendations in the observation group were significantly higher than those in the routine group ( p < 0.001). No significant difference in the Hemodialysis Self-Management Instrument (HDSMI) scores on the day of discharge between the two groups was found ( p > 0.05). After 6 months of follow-up, the observation group showed significantly higher scores of partnership, problem solving, self-management execution and emotional processing than the routine group ( p < 0.001). Both groups had no significant difference in the scores of Kidney Disease-Targeted Areas (KDTA) and 36-Item Short Form (SF-36) on the day of discharge ( p > 0.05). After 6 months of follow-up, the scores of KDTA and SF-36 in the observation group were significantly higher than those in the routine group ( p < 0.001). The incidence of HD complications in the observation group (7.41%) was significantly lower than that in the routine group (21.52%) ( p < 0.05). Conclusion Internet Plus-based continuous nursing can effectively improve treatment adherence, self-management behaviors as well as quality of life in patients, and reduce the incidence of HD complications.

Background and Objectives : The assessment of cardiac function in patients with end-stage renal disease (ESRD) is vital due to their high cardiovascular risk. However, contemporary echocardiographic indices and their association with hemodialysis-to-hemodiafiltration transfer are underreported in this population. Materials and Methods : This prospective cohort study enrolled 36 ESRD patients undergoing hemodialysis-to-hemodiafiltration transfer, with baseline and 3-month post-transfer comprehensive echocardiographic assessments. The key parameters included the global work index, global constructed work, global wasted work (GWW), global work efficiency (GWE), and global longitudinal strain (GLS), with secondary measures from conventional echocardiography. The baseline measures were compared to general population reference values and changes pre- to post-transfer were analyzed using the Mann-Whitney U test. Results : Patients exhibited significant deviations from reference ranges in GWW (179.0 vs. 53.0-122.2 mmHg%), GWE (90.0 vs. 53.0-122.2%), and GLS (-16.0 vs. -24.0-(-16.0)%). Post-transfer left ventricular myocardial work and longitudinal strain remained unchanged ( p > 0.05), except for increased GWW (179.0, IQR 148.0-217.0 to 233.5, IQR 159.0-315.0 mmHg%, p = 0.037) and improved mid-inferior peak systolic longitudinal strain ((-17.0, IQR -19.0-(-11.0) to -18.7, IQR -20.0-(-18.0)%, p = 0.016). The enrolled patients also showed higher left atrial diameters, left ventricular volumes, and mass, with impaired systolic function in both ventricles compared to reference values. Conclusions : This study highlights baseline impairments in contemporary echocardiographic measures (GWW, GWE, GLS) in ESRD patients versus reference values, but found no association between hemodialysis-to-hemodiafiltration transfer and most myocardial work and strain parameters.

Objective: To evaluate the effect of multiple single cannulation technique on the complications of arteriovenous fistula., Methods: A comprehensive literature search was conducted to investigate the impact of multiple single cannulation technique on the complications of arteriovenous fistula. The search was performed in both Chinese and English databases including Wanfang Medicine, China National Knowledge Infrastructure, Vip, Pubmed, Embase, and The Cochrane Library, with a search period up to December 20, 2023. Following literature screening and data extraction, the quality of the included studies was assessed using the Cochrane Bias Assessment Tool for Randomized Controlled Trials. Statistical analysis was performed using Review Manager version 5.3., Results: Thirteen papers, totaling 1299 patients, were included in the analysis. The experimental group consisted of 646 patients, while the control group had 595 patients. The meta-analysis revealed that the multiple single cannulation technique was more effective than rope ladder cannulation and buttonhole cannulation in reducing the incidence of angiomas (odds ratio [OR] = 0.19; 95% confidence interval [CI] = 0.10-0.35), stenosis (OR = 0.22; 95% CI 0.13-0.39), thrombosis (OR = 0.17; 95% CI = 0.07-0.39), and blood seepage (OR = 0.13; 95% CI = 0.08-0.21) of arteriovenous fistulas (P < .05). Additionally, it was found to increase the success rate of nurses' single cannulation (OR = 4.20; 95% CI = 1.78-9.95) of arteriovenous fistulas (P < .05)., Conclusion: Multiple single cannulation technique could effectively reduce the incidence of complications of arteriovenous fistula, improve the success rate of cannulation, prolong the life span of arteriovenous fistula, and prolong the survival cycle of hemodialysis patients., Competing Interests: All authors of this article declare no conflict of interest., (Copyright © 2024 the Author(s).

Background: To investigate the effect of dilating small blood vessels using a balloon dilation (BD) technique on the occurrence of radio-cephalic autogenous arteriovenous fistulas in terms of patency, blood flow, and vein diameter (VD)., Methods: The subjects included in this study were all patients with chronic renal failure and required radio-cephalic arteriovenous fistula surgery for the first time and had not received dialysis before. Patients with VDs <2 mm were included as study subjects. They were either assigned treatment using a BD group or a control group that received hydrostatic dilation. The differences between the 2 groups were analyzed in terms of patency, blood flow, and VD., Results: A total of 22 patients were enrolled in the balloon dilatation group and 20 patients in the control group. The diameters of cephalic veins (mm) of the experimental and control group were compared at various time points: immediately postoperation, 2.89 ± 0.42 versus 1.99 ± 0.28 (P < .001); 1 week later, 3.16 ± 0.59 versus 2.66 ± 0.60 (P = .022); 1 month later, 3.76 ± 0.91 versus 3.18 ± 0.83 (P = .087); and 2 months later, 4.08 ± 1.15 versus 3.38 ± 1.13 (P = .169). Brachial artery flows (mL/min) of the 2 groups at various time points were given as follows: immediately postoperation, 413.49 ± 145.09 versus 235.61 ± 87.77 (P < .001); 1 week later, 563.26 ± 206.83 versus 331.30 ± 126.78 (P < .001); 1 month later, 679.34 ± 218.56 versus 376.79 ± 156.25 (P < .001); and 2 months later, 736.31 ± 202.61 versus 394.60 ± 161.96 (P < .001). The primary patency at 1 year for the experimental group was 61.9% compared to 11.1% for the control group (P = .045). Similarly, the secondary patency rates at 1 year were 90.5% for the experimental group and 55.6% for the control group (P = .030). The results showed that the functional primary patency rate within 1 year was 57.1% versus 16.7% (P = .032), and the functional secondary patency rate within 1 year was 85.7% versus 50.0% (P = .038)., Conclusion Subsections: BD has obvious advantages over hydrostatic dilation for chronic renal failure patients with small veins in establishing arteriovenous fistula in terms of patency and blood flow., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Severe Neonatal Jaundice (SNJ) causes long-term neurocognitive impairment, cerebral palsy, auditory neuropathy, deafness, or death. We developed a mathematical model for allo-hemodialysis as a potential blood purification method for the treatment of SNJ in term or near-term infants. With allo-hemodialysis (allo-HD), the neonate's blood flows through hollow fibers of a miniature 0.075 m 2 hemodialyzer, while the blood of a healthy adult ("buddy") flows counter-currently through the dialysate compartment. We simulated the kinetics of unconjugated bilirubin in allo-hemodialysis with neonate blood flow rates of 12.5 and 15 mL/min (for a 2.5 kg and 3.5 kg neonate, respectively), and 30 mL/min for the buddy. Bilirubin production rates in neonate and buddy were set to 6 and 3 mg/kg/day, respectively. Buddy bilirubin conjugation rate was calculated to obtain normal steady-state bilirubin levels. Albumin levels were set to 1.1, 2.1, 3.1 g/dL for the neonate and 3.3 g/dL for the buddy. Model simulations suggest that a 6-h allo-hemodialysis session could reduce neonatal bilirubin levels by > 35% and that this modality would be particularly effective with low neonatal serum albumin levels. Due to the high bilirubin conjugation capacity of an adult's healthy liver and the larger distribution volume, the buddy's bilirubin level increases only transiently during allo-hemodialysis. Our modelling suggests that a single allo-hemodialysis session may lower neonatal unconjugated bilirubin levels effectively. If corroborated in ex-vivo, animal, and clinical studies, this bilirubin reduction could lower the risks associated with SNJ, especially kernicterus, and possibly avoiding the morbidity associated with exchange transfusions., (© 2024.

Background: Patients undergoing maintenance hemodialysis face heightened vulnerability during disasters like tropical cyclones, yet there is sparse research on their treatment-related challenges and countermeasures. This scoping review aims to highlight the issues maintenance hemodialysis patients encounter following tropical cyclones., Methods: A systematic scoping review of 19 articles from 2000 to 2023 was conducted, evaluating eligibility against predefined criteria., Results: Hemodialysis patients encounter substantial challenges during and after tropical cyclones in the United States, Puerto Rico, Australia, and Taiwan. Thematic analysis identified 3 themes related to "challenges" (Hemodialysis health-related challenges, socially relevant challenges, and challenges of management inefficiencies). "Recommendations" comprised 4 themes and 4 phases across the "mitigation phase" (fortifying healthcare infrastructure and mobilizing community-focused risk mitigation initiatives), "preparedness" (emergency plan development, training, and patient education), "response" (activation of emergency plans and providing emergency healthcare services), and "recovery" (intersectoral collaboration for recovery and rebuilding)., Conclusion: This scoping review underscores challenges confronted by patients undergoing maintenance hemodialysis post-tropical cyclones, highlighting the urgent need for targeted strategies to ensure the continuity of dialysis care during and after such disasters.

5wPatients with end stage kidney disease (ESKD) who receive in-center hemodialysis are disproportionately vulnerable to extreme weather events, including hurricanes and heat waves, that may disrupt access to healthcare providers, and life-sustaining treatments. This current era of climate-driven compounding disasters is progressively elevating the level of threat to the health and well-being of patients with ESKD. This analysis brings together multi-disciplinary expertise to explore the contours of this increasingly complex risk landscape. Despite the challenges, important advances have been made for safeguarding this medically high-risk patient population. Hemodialysis services providers have devised innovative systems for preparing their patients and sustaining, or rapidly reestablishing, hemodialysis services in the aftermath of a disaster, and maintaining open lines of communication with their caseloads of ESKD patients throughout all phases of the event. A description of lessons learned along the path towards improved patient support in disasters, is provided. The article concludes with a detailed case example, describing dialysis providers' effective response throughout Hurricane Ian's passage across the State of Florida in 2022. Based on lessons learned, this analysis outlines strategies for protecting patients with ESKD that may be adapted for future climate-potentiated disaster scenarios.

Background: Frequent hemodialysis provided more than three times per week may lower mortality and improve health-related quality of life. Yet, the evidence is inconclusive. We evaluated the benefits and harms of frequent hemodialysis in people with kidney failure compared with standard hemodialysis., Methods: We performed a systematic review of randomized controlled trials including adults on hemodialysis with highly sensitive searching in MEDLINE, Embase, CENTRAL, and Google Scholar on 3 January 2024. Data were pooled using random-effects meta-analysis. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. We adjudicated evidence certainty using GRADE., Results: From 11,142 unique citations, only seven studies involving 518 participants proved eligible. The effects of frequent hemodialysis on physical and mental health were imprecise due to few data. Frequent hemodialysis probably had uncertain effect on death from all cause compared with standard hemodialysis (relative risk 0.79, 95% confidence interval 0.33-1.91, low certainty evidence). Data were not reported for death from cardiovascular causes, major cardiovascular events, fatigue or vascular access., Conclusion: The evidentiary basis for frequent hemodialysis is incomplete due to clinical trials with few or no events reported for mortality and cardiovascular outcome measures and few participants in which patient-reported outcomes including health-related quality of life and symptoms were reported., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Natale et al.

The frequency of percutaneous transluminal angioplasty (PTA) procedures has substantially increased, but its effect on vascular access recreation (VAR) remains inconclusive. We conducted a population-based retrospective analysis of Taiwan hemodialysis (HD) centers from 2004 to 2012. Data was accumulated into center-level characteristics, including patients' demographics, baseline characteristics, PTA procedures, and VAR. Center-level characteristics were summarized annually using appropriate measures. A mixed model assessed the association between PTA frequency and VAR rates, considering within-center correlation and adjusting for potential confounders. A total of 82,005 patients (mean age 62.7 ± 13.9 years, 50.5% male, 48.5% with diabetes mellitus) from 820 HD centers were analyzed. From 2004 to 2012, PTA frequency significantly increased from 1.24 to 3.23 per 1000 HD sessions, while VAR rates did not decline as expected (0.5-0.8 per 1000 HD sessions). Compared with the HD centers of infrequent use of PTA (annual lowest quartile, range 0.39-1.20 per 1000 HD sessions), the ones of frequent use (annual highest quartile, range 2.52-5.10 per 1000 HD sessions) didn't have lower VAR (range 0.54-0.99 vs. 0.50-0.91 per 1000 HD sessions, respectively). After controlling the potential confounders, the HD centers' PTA rates were not significantly associated with lower VAR rates (- 2.6, 95% confidence interval: - 30.3; 25.0, p = 0.85). Frequent use of PTA does not seem to improve VA patency at the center level, with no significant association identified with lower VAR. The indication of PTA in daily practice should be re-evaluated in terms of its efficiency in lowering VAR., (© 2024. The Author(s).)

Naphthalene is a widely used industrial and household chemical in the form of mothballs, but it has rarely been an agent of poisoning worldwide. We describe a case of ingestional naphthalene poisoning with a good outcome after proper management. A 20-year-old boy with a history of seizure disorder and mental retardation presented with abdominal pain, vomiting, burning micturition, and blood in the urine for 2-3 days. On examination, it was found that he had ingested six to eight mothballs and presented 2 days later with hemolysis and methemoglobinemia. He was given intravenous methylene blue, N-acetylcysteine, and ascorbic acid, besides supportive treatment, but the condition did not improve. The patient then underwent plasmapheresis. After two sessions, he showed improvement in the form of decreasing hemolysis. Renal replacement therapy in the form of hemodialysis was performed. Gradually, his condition improved, and concurrent psychiatric assessment and treatment were also provided. The patient was discharged after 15 days., (© Journal of the Association of Physicians of India 2024.)

Chronic kidney disease has become a significant global health issue, with some individuals progressing to endstage renal disease (ESRD) and requiring renal replacement therapy. For ESRD patients undergoing haemodialysis, the first step is to establish vascular access. In emergency situations, inserting a haemodialysis catheter (HDC) into the central vein is often the most appropriate approach; the right internal jugular vein (IJV) is considered the optimal site for catheterisation. However, catheter placement in the right IJV can sometimes lead to inadvertent entry into an abnormal position. Herein, we present a unique case in which the tip of the HDC was noted to have misplaced into the left IJV due to the patient's multiple central venous stenosis (CVS). This case highlights the clinical manifestation of HDC misplacement, with CVS being the underlying cause. Therefore, healthcare providers should pay adequate attention to CVS.

Background: Hemodialysis requires reliable, recurrent access to the circulatory system. Central venous tunneled dialysis catheters (TDC) are frequently used for patients receiving hemodialysis as a bridge to permanent vascular access or as a final option. TDC are prone to complications such as infection and dysfunction., Objectives: To assess the prevalence and predictors of TDC dysfunction in a cohort of chronic hemodialysis patients., Methods: This single-center, retrospective study was based on data from an electronic database of chronic hemodialysis patients during 5 years of follow-up., Results: A total of 625 TDC were inserted in 361 patients, of which 234 (37.4%) were replaced due to dysfunction. The main insertion site was the right internal jugular vein. Diabetes mellitus was an important predictor of TDC dysfunction and was significantly correlated with TDC extraction. Chronic anticoagulation and antiplatelet treatment did not affect the rate of TDC dysfunction or replacement., Conclusions: TDC use for chronic dialysis patients is increasing and dysfunction is a major problem. In our study, we highlighted the high prevalence of TDC dysfunction and the need for further research to improve hemodialysis access as well as TDC patency and function.

Children requiring long-term kidney replacement therapy are a "rare disease" cohort. While the basic technical requirements for hemodialysis (HD) are similar in children and adults, key aspects of the child's cardiovascular anatomy and hemodynamic specifications must be considered. In this article, we describe the technical requirements for long-term HD therapy for children and the devices that are currently available around the world. We highlight the characteristics and major technical shortcomings of permanent central venous catheters, dialyzers, dialysis machines, and software available to clinicians who care for children. We show that currently available HD machines are not equipped with appropriately small circuits and sensitive control mechanisms to perform safe and effective HD in the youngest patients. Manufacturers limit their liability, and health regulatory agencies permit the use of devices, only in children according to the manufacturers' pre-specified weight limitations. Although registries show that 6-23% of children starting long-term HD weigh less than 15 kg, currently, there is only one long-term HD device that is cleared for use in children weighing 10 to 15 kg and none is available and labelled for use in children weighing less than 10 kg anywhere in the world. Thus, many children are being treated "off-label" and are subject to interventions delivered by medical devices that lack pediatric safety and efficacy data. Moreover, recent improvements in dialysis technology offered to adult patients are denied to most children. We, in turn, advocate for concerted action by pediatric nephrologists, industry, and health regulatory agencies to increase the development of dedicated HD machines and equipment for children., (© 2023.

Introduction: Femoral vein transposition is one of the final resorts for vascular access in patients with exhaustion of upper limb venous patrimony and central venous occlusive disease. Its major pitfalls include hemodialysis access-induced distal ischemia and infection. Surgical procedures may be warranted to preserve vascular access if ischemia develops. Several techniques are reported in the literature for femoral vein transposition., Case Report: We expose an endoscopic femoral vein harvesting as an alternative to the single thigh incision in order to avoid its associated complications. In the setting of ischemia, proximalization of arterial inflow was used to manage femoral vein transposition associated limb ischemia., Conclusion: This case report aims to expose the aforementioned unreported surgical techniques for lower limb arteriovenous fistula, its advantages, and pitfalls, as well as considerations on its future use., (© 2024 Wiley Periodicals LLC.)

Moderate physical activity is related to reduced mortality in hemodialysis patients. However, most hemodialysis patients have low physical activity levels for complex reasons. This study investigated the determinants of moderate-to-high physical activity levels and whether psychosocial correlates are associated with engagement in moderate-to-high physical activity among hemodialysis patients. A cross-sectional survey was conducted with 134 hemodialysis outpatients, aged 64.7 years, in three hemodialysis centers in Taiwan. Data on sociodemographics, comorbidities, lifestyles, and psychosocial correlates, including perceived benefits, barriers, and self-efficacy of physical activity, were collected. Multiple logistic regression analyses were performed. Results showed that patients with moderate-to-high physical activity levels constituted a significantly lower proportion of current smokers and had fewer perceived physical activity barriers and higher self-efficacy of physical activity compared with those with low levels. After adjusting for potential sociodemographic covariates, current employment, nonsmoking status, and high self-efficacy of physical activity were significantly associated with moderate-to-high physical activity levels. Developing strategies to improve the self-efficacy of physical activity, support employment, and enhance anti-smoking campaigns in hemodialysis patients can help them engage in moderate-to-high levels of physical activity., (© 2024 John Wiley & Sons Australia, Ltd.)

Objectives: Reduced handgrip strength (HGS) is associated with adverse clinical outcomes. We analyzed and compared associations of HGS with mortality risk in dialysis patients, using different normalization methods of HGS., Methods: HGS and clinical and laboratory parameters were measured in a cohort of 446 incident dialysis patients (median age 56 y, 62% men). The area under the receiver operating characteristic curve (AUROC) was used to compare different normalization methods of HGS as predictors of mortality: absolute HGS in kilograms; HGS normalized to height, weight, or body mass index; and HGS of a reference population of sex-matched controls (percentage of the mean HGS value [HGS%]). Multivariate linear regression analysis was used to assess HGS predictors. Competing risk regression analysis was used to evaluate 5-year all-cause mortality risk. Differences in survival time between HGS% tertiles were quantitated by analyzing the restricted mean survival time., Results: The AUROC for HGS% was higher than the AUROCs for absolute or normalized HGS values. Compared with the high HGS% tertile, low HGS% (subdistribution hazard ratio [sHR] = 2.36; 95% CI, 1.19-3.70) and middle HGS% (sHR = 1.79; 95% CI, 1.12-2.74) tertiles were independently associated with higher all-cause mortality and those with high HGS% tertile survived on average 7.95 mo (95% CI, 3.61-12.28) and 18.99 mo (95% CI, 14.42-23.57) longer compared with middle and low HGS% tertile, respectively., Conclusions: HGS% was a strong predictor of all-cause mortality risk in incident dialysis patients and a better discriminator of survival than absolute HGS or HGS normalized to body size dimensions., Competing Interests: Declaration of competing interest B.

Background: Autologous arteriovenous fistulae (AVFs) are the best type of vascular access in patients with kidney failure. However, the conventional technique has a high failure rate. We performed a randomised controlled trial to investigate whether the no-touch technique has a higher maturation and patency rate than that of the conventional technique for creating AVFs., Methods: This study was a single-centre randomised controlled trial involving patients with kidney failure requiring an AVF for haemodialysis access. A total of 179 patients undergoing their first radial artery-cephalic fistula were randomized 1:1 to the no-touch technique (n = 90) or conventional technique (n = 89). The maturation and patency rate of the two techniques were compared and analysed., Results: The preoperative baseline data showed no differences between groups. When comparing the no-touch technique to the conventional technique, the maturation rate was 93% vs. 89% and the 1-year primary function patency was 72% vs. 62%, respectively. Factors associated with AVF failure included age > 55 years (OR = 2.417, 95% CI 1.242-4.703), female sex (OR = 2.149, 95% CI 1.099-4.202), and vein diameter ≤ 1.8 mm (OR = 3.664, 95% CI 1.714-7.832). For patients with small veins the maturation rate was 92.98% vs. 80% and the 1-year primary function patency was 68.42% vs. 40% for the no-touch technique and conventional technique, respectively., Conclusions: The no-touch technique has a higher maturation and patency rate than the conventional technique for creating an autologous AVF, especially in patients with small veins. This technique may provide a better outcome for patients with small cephalic veins., (© 2024. The Author(s) under exclusive licence to Italian Society of Nephrology.)

Objective: The 'Connected We St@nd' is an online self-management intervention programme for people receiving in-centre haemodialysis and family caregivers that combines an educational and psychosocial support component. This study aimed to evaluate its feasibility and acceptability before proceeding to a large-scale trial., Design: This was a pre-post single-arm feasibility pilot study conducted with adults undergoing in-centre haemodialysis and family caregivers., Methods: Feasibility was based on eligibility, consent, retention, completion and intervention adherence rates, while acceptability was assessed in post-intervention focus group interviews., Results: Twenty-six people (16 adults on haemodialysis and 10 family caregivers) recruited through social networks completed the intervention. Consent, retention and completion rates were excellent (>90%) and eligibility (77.5%) and intervention adherence were satisfactory (69% for the psychosocial support sessions). Qualitative findings revealed that participants shared positive feelings regarding their participation in the programme. The valuable interactions with group peers and health psychologists during the support sessions, the perception of the adequacy and coherence of the programme's contents and materials and the participants' confidence in using the platform developed to deliver the intervention were some of the aspects highlighted as facilitators of intervention acceptability. Additionally, people on haemodialysis and caregivers reported that participation in the programme brought several educational and emotional benefits (e.g., additional disease-related knowledge, improved communication and coping skills, greater confidence in managing dialysis complications or caregiving demands) that helped increase their self-management skills and psychosocial adjustment to the demands of kidney failure and renal therapies., Conclusions: The results suggested that the 'Connected We St@nd' programme is likely to be feasible and acceptable for adults on haemodialysis and family caregivers, thus representing a promising resource for the future of interdisciplinary renal rehabilitation. Suggestions were made to fine-tune the intervention design to proceed with a large-scale trial., (© 2024 The Authors.

Background: Haemodialysis units are now managing an increasing number of patients with varying needs and levels of acuity. To maintain safety, haemodialysis patients must be placed in the most appropriate dialysis unit that has the required human and physical resources to care for them. The first step towards achieving these goals is to develop a tool specific to haemodialysis units to effectively measure patient acuity., Objective: To develop a haemodialysis acuity tool, utilising a focus group approach, in assessing patient's suitability for a specific dialysis location thus ensuring patient safety., Design: This is a cross-sectional qualitative study via a focus group approach., Participants: Participants were nurse unit managers and team leaders of a District Renal Service., Approach: Participants were interviewed to explore their views on the elements and measures identified in the research aims. Themes for interviews were informed by current literature on acuity tools for haemodialysis patients' admission to the dialysis units. Interviews were recorded and transcribed verbatim and progressively analysed using a thematic analysis approach., Results: Ten nurse unit managers/team leaders (100%) were interviewed and thematic analysis of the transcripts was conducted utilising the deductive approach. Five themes were identified which will form the main categories in the development of the tool, namely: Age/frailty; co-morbidity; physical; dialysis; and psychosocial., Conclusion: This study is instrumental in the development of the haemodialysis acuity tool which can be used in allocating dialysis location specific to patient's needs and available resources. The tool can also be used in analysing patient care processes and resource requirements based on the patients' and unit's profile., (© 2024 The Authors.

Objective: Hyperphosphatemia is a common complication in patients with kidney failure, despite the use of phosphate binders. Vitamin B3, either in the form of niacin or niacinamide (NAM), shows potential as "add-on" treatment to reduce serum phosphate concentrations in this population. NAM seems to lack many of the side effects that are observed with niacin. The aim of this study was to investigate whether NAM is an effective and acceptable treatment in reducing serum phosphate concentrations in patients with kidney failure., Methods: DiaNia was a double-blind placebo-controlled randomized crossover trial, comparing NAM (250-500 mg/day) to placebo as "add-on" treatment to an individual treatment with approved phosphate binders for 12 weeks in patients receiving hemodialysis. The primary outcome was serum phosphate concentrations, and the secondary outcomes were platelet counts as well as drop-outs due to side effects. Data were analyzed using both per-protocol and intention-to-treat analyses., Results: Mean age of the per-protocol population (n = 26) was 63.6 ± 17.2 years and 53.8% were men. NAM treatment significantly reduced serum phosphate with 0.59 mg/dL (p = .03). Linear mixed-effects models demonstrated superiority of 12 weeks NAM over 12 weeks placebo with a between-treatment difference of 0.77 mg/dL (95% CI 0.010, 1.43; P = .03). Similar results, although not significant, were found in the intention-to-treat population. We found no between-treatment differences in platelet counts and during the NAM treatment we observed 3 drop-outs due to side effects (8.6%)., Conclusion: NAM is effective in reducing serum phosphate concentrations in patients with kidney failure receiving hemodialysis. In addition, NAM is well-tolerated and seems not to increase the risk of thrombocytopenia. Thus, NAM can be valuable as "add-on" treatment to combat hyperphosphatemia in patients with kidney failure. However, more research in larger populations is needed to confirm this., (Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: Nurse-sensitive indicators (NSI) assess the quality of nursing care provided to patients. These indicators assess the structures (supportive measures), processes (nursing actions) and outcomes of care. The McIntyre Audit Tool (MAT) was developed to measure haemodialysis NSIs., Objectives: The objective of this study is to evaluate the feasibility and utility of the MAT in measuring haemodialysis NSIs in clinical practice., Design: Multisite nonrandomized feasibility study., Participants: A convenience sample of nurses (n = 30) were recruited from two haemodialysis units in Australia., Measurements: Participants completed the MAT once daily for 1 week, to measure the extent the clinical indicators were being met. Feasibility data including utility and acceptability of the tool was collected once from each participant. Data were analysed descriptively., Results: Participants completed a total of 97 audits. Results revealed the majority of structural (75%) and process indicators (73%) were being achieved although some variation between sites was observed. Results for the outcome indicators showed more variation (5.9%-94.1). Feasibility results found most nurses (79%) took <5 min to complete the MAT and found the tool easy to use (91.7%). Most participants (83.3%) reported audits could be completed during a shift and auditing was easily implemented (79.2%)., Conclusion: Use of the MAT in clinical practice is a feasible and acceptable way of auditing the quality of haemodialysis nursing practice. The tool could be used to establish minimum standards and improve the quality of nursing care in haemodialysis units, also enabling benchmarking between services., (© 2023 The Authors.

Background: Nocturnal hemodialysis (nHD) restores the attenuated brachial artery vasodilator responsiveness of patients receiving conventional intermittent hemodialysis (iHD). Its impact on coronary vasodilatation is unknown., Methods: We evaluated 25 patients on hemodialysis who fulfilled transplant criteria: 15 on iHD (4-hour sessions, 3 d/wk) and 10 on nHD (≈40 h/wk over 8-10-hour sessions) plus 6 control participants. Following diagnostic angiography, left anterior descending (LAD) coronary flow reserve and mean luminal diameter were quantified at baseline and during sequential intracoronary administration of adenosine (infusion and bolus), nitroglycerin (bolus), acetylcholine (infusion), acetylcholine coinfused with vitamin C, and, finally, sublingual nitroglycerin., Results: Coronary flow reserve in those receiving nHD was augmented relative to iHD (3.28±0.26 versus 2.17±0.12 [mean±SEM]; P <0.03) but attenuated, relative to controls (4.80±0.63; P =0.011). Luminal dilatations induced by intracoronary adenosine and nitroglycerin were similar in nHD and controls but blunted in the iHD cohort ( P <0.05 versus both). ACh elicited vasodilatation in controls but constriction in both dialysis groups (both P <0.05, versus control); vitamin C coinfusion had no effect. Sublingual nitroglycerin increased mid-left anterior descending diameter and reduced mean arterial pressure in controls (+15.2±2.68%; -16.00±1.60%) and in nHD recipients (+14.78±5.46%; -15.82±1.32%); iHD responses were markedly attenuated (+1.9±0.86%; -5.89±1.41%; P <0.05, all comparisons)., Conclusions: Coronary and systemic vasodilator responsiveness to both adenosine and nitroglycerin is augmented in patients receiving nHD relative to those receiving iHD, whereas vasoconstrictor responsiveness to acetylcholine does not differ. By improving coronary conduit and microvascular function, nHD may reduce the cardiovascular risk of patients on dialysis., Competing Interests: None.
