Abstract
OBJECTIVE This study aimed to assess whether an obesity paradox (lower event rates with higher body mass index [BMI]) exists in participants with advanced chronic kidney disease (CKD) and chronic coronary disease in the International Study of Comparative Health Effectiveness of Medical and Invasive Approaches (ISCHEMIA)-CKD, and whether BMI modified the effect of initial treatment strategy. METHODS Baseline BMI was analyzed as both a continuous and categorical variable (< 25, ≥ 25 to < 30, ≥ 30 kg/m2). Associations between BMI and the primary outcome of all-cause death or myocardial infarction (D/MI), and all-cause death, cardiovascular death, and MI individually were estimated. Associations with health status were also evaluated using the Seattle Angina Questionnaire-7, the Rose Dyspnea Scale, and the EuroQol-5D Visual Analog Scale. RESULTS Body mass index ≥ 30 kg/m2 vs < 25 kg/m2 demonstrated increased risk for MI (hazard ratio [HR] [95% confidence interval] = 1.81 [1.12-2.92]) and for D/MI (HR 1.45 [1.06-1.96]) with a HR for MI of 1.22 (1.05-1.40) per 5 kg/m2 increase in BMI in unadjusted analysis. In multivariate analyses, a BMI ≥ 30 kg/m2 was marginally associated with D/MI (HR 1.43 [1.00-2.04]) and greater dyspnea throughout follow-up (P < .05 at all time points). Heterogeneity of treatment effect between baseline BMI was not evident for any outcome. CONCLUSIONS In the ISCHEMIA-CKD trial, an obesity paradox was not detected. Higher BMI was associated with worse dyspnea, and a trend toward increased D/MI and MI risk. Larger studies to validate these findings are warranted.

Ghandour H, Cataneo JL, Asha A, Jaeger JK, Jacobs CE, Schwartz LB, El Khoury R. Slowly moving the needle away from Fistula First. J Vasc Surg 2024; 79:382-387. [PMID: 37952784 DOI: 10.1016/j.jvs.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 11/02/2023] [Accepted: 11/05/2023] [Indexed: 11/14/2023]
Abstract
OBJECTIVE In 2019, the management of end-stage kidney disease (ESKD) shifted away from "Fistula First" (FF) to "ESKD Life-Plan: Patient Life-Plan First then Access Needs." Indeed, some patients exhibit such excessive comorbidity that even relatively minor vascular surgery may be complicated. The purpose of this study was to retrospectively assess complications and mortality (and delineate operative futility) in patients undergoing arteriovenous fistula (AVF) creation in the FF era. METHODS Consecutive AVFs created in a single institution before 2021 were retrospectively reviewed. Operative futility was defined as never-accessed fistula, no initiation of dialysis, failure of access maturation (despite secondary intervention), hemodialysis access-induced distal ischemia requiring ligation, early loss of secondary patency, and/or patient mortality within the first 6 postoperative months. RESULTS A total of 401 AVFs were created including radial-cephalic (44%), brachial-cephalic (41%), and brachial-basilic (15%) constructions. Patients exhibited a mean age of 69 ± 15 years; 63% were male, and most (74%) were already being hemodialyzed at the time of fistula creation. Forty-five patients (11%) suffered a cardiac event, and five patients died (1%) within 90 days of their access surgery. Perioperative cardiac events were significantly more common after age 80 (19% vs 8%; P = .004); age >80 years was an independent predictor of major 90-day complications (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.04-3.39; P = .036) and the sole independent predictor of major morbidity defined as cardiopulmonary complications, stroke, or death within the first year (OR, 2.01; 95% CI, 1.24-3.25; P = .004). Operative futility was encountered in 52% of the cohort (n = 208 patients): 40% (n = 160) of primary AVFs failed to mature despite assistance, 19% (n = 77) had lost secondary patency by 6 months, 13% of patients (n = 53) were never started on dialysis after access creation, 4% (n = 16) were dead by 6 months, 2% of AVFs (n = 10) matured but were never accessed, and 2% (n = 9) required ligation for hemodialysis access-induced distal ischemia. Not surprisingly, the sole independent protector against operative futility was that catheter-based dialysis had been established prior to AVF creation (OR, 0.36; 95% CI, 0.22-0.59; P < .01). CONCLUSIONS Approximately 50% of primary AVF operations performed in the aggressive FF era were deemed futile. Octogenarians were particularly prone to futility and complications during this era. A paradigm shift, from FF to an "ESKD Life-Plan" will, hopefully, more thoughtfully match vascular access strategies to individual patient needs.

Abstract
BACKGROUND Pediatric patients with chronic kidney disease (CKD) frequently present an inadequate nutritional profile and musculoskeletal impairments. We investigated sarcopenia and its related traits in children and adolescents with CKD. METHODS A cross-sectional study that enrolled pediatric patients with CKD (≥ 4 and < 18 years old). Physical function was assessed by handgrip strength and the 60-s sit-to-stand (STS-60) tests. Body composition measurement was performed by bioelectrical impedance analysis and anthropometry through mid-upper arm circumference (MUAC). Normative reference values from healthy pediatrics were used for identifying poor physical function and low MUAC. Probable sarcopenia was considered as low handgrip strength, whereas sarcopenia was defined by adding low MUAC. RESULTS Twenty-two pediatric patients with CKD (11 ± 4 years and 59% boys) were evaluated; eight on peritoneal dialysis (36%), six on hemodialysis (27%), and eight non-dialysis (36%). Regarding sarcopenia traits, we observed low physical function by handgrip strength and STS-60 in 59% and 100% of the patients, respectively, while low MUAC in 77%. Probable sarcopenia was found in 9% and sarcopenia in 50%, but prevalence did not differ among stages. Handgrip strength was strongly associated with MUAC (r = 0.90; p < 0.001); on the other hand, the STS-60 was not significantly associated with any of the body composition variables. CONCLUSION Among pediatric patients with CKD, the prevalence of sarcopenia and its related traits was high. Nephrology professionals should consider the assessment of sarcopenia in this population, while more evidence is needed to determine its prognostic value.

Abstract
Global estimates exhibit that one million people have end-stage renal disease, a disease-state characterized by irreversible loss of kidney structure and function, thus necessitating renal replacement therapy. The disease-state, oxidative stress, inflammatory responses, as well as the treatment procedure can have damaging effects on the genetic material. Therefore, the present study was carried out to investigate DNA damage (basal and oxidative) using the comet assay in peripheral blood leukocytes of patients (n = 200) with stage V Chronic Kidney Disease (on dialysis and those recommended but yet to initiate dialysis) and compare it to that in controls (n = 210). Basal DNA damage was significantly elevated (1.13x, p ≤ 0.001) in patients (46.23 ± 0.58% DNA in tail) compared to controls (40.85 ± 0.61% DNA in tail). Oxidative DNA damage was also significantly (p ≤ 0.001) higher in patients (9.18 ± 0.49 vs. 2.59 ± 0.19% tail DNA) compared to controls. Twice-a-week dialysis regimen patients had significantly elevated % tail DNA and Damage Index compared to the non-dialyzed and to the once-a-week dialysis group implying dialysis- induced mechanical stress and blood-dialyzer membrane interactions as probable contributors to elevated DNA damage. The present study with a statistically significant power implies higher disease-associated as well as maintenance therapy (hemodialysis)-induced basal and oxidatively damaged DNA, which if not repaired has the potential to initiate carcinogenesis. These findings mark the need for improvement and development of interventional therapies for delaying disease progression and associated co-morbidities so as to improve life expectancy of patients with kidney disease.

Abstract
INTRODUCTION Impaired awareness of hypoglycemia (IAH) refers to a diminished capacity to detect hypoglycemia. IAH can result in severe and even life-threatening outcomes for individuals with diabetes, especially those in advanced stages of the disease. This study aimed to assess the prevalence of IAH in people with diabetes on hemodialysis. RESEARCH DESIGN AND METHODS We conducted a single-center audit to assess the prevalence of IAH using the Clarke questionnaire. Simultaneously, we measured fear of hypoglycemia with an adapted version of the Hypoglycemia Survey and recorded the incidence of severe hypoglycemia. Data were presented as mean±SD or counts/percentages. Logistic regression was then employed to analyze the association between IAH and various sociodemographic and clinical factors. RESULTS We included 56 participants with diabetes on hemodialysis, with a mean age of 67.2 years (±12.9), of whom 51.8% were male. The ethnic distribution was 23.2% white, 23.2% black, 19.6% Asian, and 33.9% unspecified. The mean HbA1c was 52 mmol/mol (±18.6). The majority (91.1%) had a diagnosis of type 2 diabetes, and 55.4% of those were treated with insulin. The use of diabetes technology was low, with 2.8% of the participants using a continuous glucose monitor. IAH prevalence was 23.2%, and among the 57 participants, 23.6% had a history of severe hypoglycemia, and 60.6% reported fear of hypoglycemia. There were no significant differences in sociodemographic and clinical characteristics between those with IAH and normal hypoglycemia awareness. CONCLUSIONS We observed that 23.2% of individuals with diabetes undergoing hemodialysis had IAH. IAH was more prevalent in people who reported a fear of hypoglycemia and had a history of severe hypoglycemia episode. The study highlights the unmet needs and disparities in access to diabetes technology within this population.

Abstract
BACKGROUND Management of edema and volume overload in patients with hypoalbuminemia, either due to nephrotic syndrome or other disease processes, can be extremely challenging. METHODS We describe the management of five patients with hypoalbuminemia and severe fluid overload using the Aquadex FlexFlow device with continuous hematocrit monitoring to guide ultrafiltration. RESULTS We report five pediatric patients ranging in age from 7 days to 11 years and in size from 2.7 to 65 kg with hypoalbuminemia due to a variety of etiologies treated with slow continuous ultrafiltration with continuous hematocrit monitoring to guide ultrafiltration using the Aquadex device. Treatment allowed successful fluid removal in all cases, without hypotension or other hemodynamic complications. CONCLUSIONS In a variety of clinical circumstances and in patients from infants to adolescence, we report that patients with diuretic-resistant fluid overload can be treated with Aquadex using continuous hematocrit monitoring to guide management to allow fluid removal without hemodynamic instability or other complications.

Abstract
Secondary hyperparathyroidism (SHPT) does not initiate as a primary dysfunction of parathyroid glands resulting from an intrinsic defect or disease but is the physiologic response of parathyroids to metabolic changes elsewhere in the body occurring over time. SHPT is a manifestation of a chronic condition that classically occurs from chronic kidney disease. In fact, given the relatively recent transition of populations from outside (agrarian) to indoor (industrial, information technology, and so forth) employment and a consequent reduction in sun exposure, combined with diets of highly processed food, vitamin D and calcium deficiencies are now the leading causes of SHPT.

Abstract
INTRODUCTION Brachial artery aneurysm (BAA) following long-standing arteriovenous fistula (AVF) ligation after renal transplantation is odd. CASE PRESENTATION Two cases of brachial artery aneurysm treated with bypass (a saphenous vein graft and a PTFE graft). In the first patient no complications were recorded whereas an infection was diagnosed after 6 months from the procedure in the second treatment. CLINICAL DISCUSSION Multiple factors activated by stress on the vessel wall followed by fistula ligation are the cause of vascular remodeling of the three layers making up the wall with possible evolution in aneurysmatic lesions. In literature the gold standard for this lesion is the surgical approach, only one endovascular procedure is reported. The traditional surgical approach uses the autologous vein or prosthetic PTFE grafts. CONCLUSION Brachial artery aneurysm is a complication that affects patients undergoing renal transplantation who have already undergone AVF ligation. In our experience autologous vein graft represented the best solution.

Abstract
Hyperammonemia is a life-threatening condition, the prognosis of which depends on a rapid reduction of ammonia. If a hepatic cause is excluded, the differential diagnosis is broad and even in adulthood includes hereditary metabolic diseases. Here, the case of a 25-year-old female patient with severe hyperammonemia refractory to standard therapy is described and the relevance of extracorporeal elimination of ammonia emphasized.

Abstract
This review aimed to assess the effectiveness of the eutectic mixture of local anaesthetics (EMLA) cream in the management of arteriovenous fistula (AVF) needle insertion pain in adult patients undergoing haemodialysis (HD) compared with other alternative interventions. The main search was conducted in November 2020 and updated in December 2021. In the search strategy, keywords and synonyms were used and multiple databases were searched with no date limitation to ensure a comprehensive search that would yield all studies relevant to the review and minimise location bias. A total of 209 studies were found in this search and filtered. After filtering through these studies, only five studies were finally included in the review. EMLA-cream was found to be effective in reducing AVF needle insertion pain among adult patients undergoing HD. Despite EMLA cream's effectiveness in reducing HD needle insertion pain and its fewer side effects, the findings of the included studies should be interpreted with caution, as there are some limitations, and further research is required.

Abstract
Objectives This study aimed to determine the risk factors associated with the failure of arteriovenous fistulae (AVF) maturation. Methods This retrospective cohort study was conducted from January 2014 to December 2018 in Sultan Qaboos University Hospital, Muscat, Oman. Patients were followed-up 3 months after surgery, and their electronic medical records were accessed for demographic and clinical data. Univariate analysis was used to determine the risk factors associated with early AVF maturation and multivariant analysis was used to determine the predictive factors for AVF failure. Results A total of 269 patients were included. Female gender was a significant factor affecting AVF maturity (P = 0.049), while age (P = 0.626), diabetes (P = 0.954), hypertension (P = 0.378), dyslipidaemia (P = 0.907), coronary artery disease (P = 0.576), cerebrovascular accident (P = 0.864), congestive heart failure (P = 0.685), previous central venous catheterisation (P = 0.05), fistula type (P = 0.863) and fistula site (P = 0.861) did not affect AVF maturation. Binary logistic regression showed that all the risk factors were insignificant. Failure of early AVF maturation affected 11.5% in the cohort. Conclusion This study found that the proportion of early AVF maturation at our hospital is at par with that in the international literature. Failure of AVF maturation was significantly associated with the female gender. These findings can help nephrologists and vascular surgeons prognosticate AVF maturation rates. However, a larger study is needed for definitive conclusions.

Abstract
BACKGROUND Children and young adults with sickle cell disease (SCD) develop kidney disease early in childhood, with some patients progressing to require dialysis and kidney transplantation. The prevalence and outcomes of children with kidney failure (chronic kidney disease stage 5) due to SCD are not well described. This study aimed to assess the outcome of children and young adults with SCD with kidney failure compared to matched children and young adults without SCD with kidney failure in a large national database. METHODS Utilizing the United States Renal Data System (USRDS), we retrospectively examined kidney failure outcomes in children and young adults with SCD from 1998 to 2019. RESULTS We identified 97 patients with SCD who developed kidney failure and identified 96 matched controls with a median age of 19 years (IQR 17, 21) at the time of kidney failure diagnosis. SCD patients had significantly shorter survival (8.4 years vs. 14.0 years, p < 0.001) and had a longer waiting time for their first transplant when compared to matched non-SCD kidney failure patients (12.1 years vs. 7.3 years, p < 0.001). CONCLUSIONS Children and young adults with SCD kidney failure have significantly higher mortality when matched to non-SCD kidney failure children and experience a longer mean time to kidney transplant.

Abstract
INTRODUCTION Patients with kidney failure experience symptoms that are often under-recognised and undermanaged. These symptoms negatively impact health-related quality of life and are associated with adverse clinical outcomes. Regular symptom assessment, using electronic patient reported outcomes measure (ePROMs) linked to systematic symptom management, could improve such outcomes. Clinical implementation of ePROMs have been successful in routine oncology care, but not used for patients on dialysis. In this study, we describe a pilot study of ePROM-based systematic symptom monitoring and management intervention in patients treated with in-centre haemodialysis. METHODS AND ANALYSIS This is a parallel-arm, controlled pilot of adult patients receiving in-centre maintenance haemodialysis. Participants in the intervention arm will complete ePROMs once a month for 6 months. ePROMs will be scored real time and the results will be shared with participants and with the clinical team. Moderate-severe symptoms will be flagged using established cut-off scores. Referral options for those symptoms will be shared with the clinical team, and additional symptom management resources will also be provided for both participants and clinicians. Participants in the control arm will be recruited at a different dialysis unit, to prevent contamination. They will receive usual care, except that they will complete ePROMs without the presentation of results to participants of the clinical team. The primary objectives of the pilot are to assess (1) the feasibility of a larger, randomised clinical effectiveness trial and (2) the acceptability of the intervention. Interviews conducted with participants and staff will be assessed using a content analysis approach. ETHICS AND DISSEMINATION Ethical approval for this study was obtained from the University Health Network (REB#21-5199) and the William Osler Health System (#23-0005). All study procedures will be conducted in accordance with the standards of University Health Network research ethics board and with the 1964 Helsinki declaration and its later amendments. Results of this study will be shared with participants, patients on dialysis and other stakeholders using lay language summaries, oral presentations to patients and nephrology professionals. We will also be publishing the results in a peer-reviewed journal and at scientific meetings. PROTOCOL VERSION 4 (16 November 2022). TRIAL REGISTRATION NUMBER NCT05515991.

Abstract
BACKGROUND Respiratory sarcopenia is characterized by the weakness of respiratory muscles associated with sarcopenia due to aging or systemic diseases such as chronic kidney disease (CKD). Patients with CKD undergoing dialysis are particularly susceptible to respiratory muscle weakness caused by factors such as fluid overload and electrolyte imbalance. This weakness not only affects ventilation but also impairs oxygen uptake and delivery to muscle tissue, potentially leading to severe sarcopenia. Thus, the objective of this study is to conduct a respiratory sarcopenia screening in patients with CKD undergoing haemodialysis (HD) and peritoneal dialysis (PD). METHODS This is an observational, cross-sectional and multicentre study conducted between March 2023 and March 2025. The study was approved by the Research Ethics Committee at two centres. Sarcopenia diagnosis is determined based on low handgrip strength and amount of appendicular skeletal muscle mass, assessed through bioelectrical impedance analysis. Respiratory sarcopenia is diagnosed in patients with sarcopenia who have low inspiratory muscle strength, evaluated through a manovacuometry test. The severity of sarcopenia and respiratory sarcopenia is defined, respectively, by low physical performance (measured using the Short Physical Performance Battery and Timed-Up and Go test) and pulmonary performance (measured through spirometry). Thus, this study will include 81 patients undergoing dialysis (41 on HD and 40 on PD) from three participating centres. DISCUSSION The literature has been focused on respiratory function in CKD; however, the relationship with sarcopenia remains understudied. We believe that, similar to appendicular skeleton muscles, the axial skeleton muscles are also likely to weaken with the presence of chronic disease, such as CKD.

Abstract
Occasionally, patients undergoing dialysis develop acute severe hypotension that requires interruption of dialysis within minutes of initiating every dialysis session. Although the underlying causes of recurrent intradialytic hypotension are evaluated extensively, including dialysis-associated allergic reactions or other possible causes, the definitive cause is sometimes missed. Dialysis is a life-sustaining procedure; therefore, prompt identification and management of the underlying cause of dialysis intolerance are crucial. Herein, we report three cases of patients undergoing dialysis who presented with hypereosinophilia-associated acute intradialytic hypotension. All three patients developed acute severe hypotension within minutes after the start of every dialysis session. The prescriptions for dialysis were changed, but episodes of intradialytic hypotension persisted. Pretreatment with methylprednisolone given intravenously before the dialysis session was also ineffective. All patients had hypereosinophilia (> 1500/μL) of different etiology. Eosinophil-lowering therapy with 0.5 mg/kg of prednisolone given orally daily was initiated, and all of them could restart dialysis without any hypotensive episodes within a few days. Our case report and literature review indicated that hypereosinophilia, regardless of its etiology, could result in severe acute hypotension shortly after the start of dialysis session. The oral administration of prednisolone daily was highly effective on hypereosinophilia-associated intradialytic hypotension, while pretreatment with intravenous corticosteroid therapy just before dialysis had no effect. Hypereosinophilia-associated acute intradialytic hypotension is an under-recognized condition; therefore, clinicians need to be aware of this clinical entity and initiate effective treatment strategies. We also provide a brief summary of previously published cases.

Abstract
Hemodialysis patients frequently require ambulance transport to the hospital for dialysis. Some patients require urgent dialysis (UD) within 24 hours of transport to hospital to avoid morbidity and mortality. UD is not available in all hospitals; therefore, predicting patients who need UD prior to hospital transport can help paramedics with destination planning. In this paper, we developed machine learning models for paramedics to predict whether a patient needs UD based on patient characteristics available at the time of ambulance transport. This paper presented a study based on ambulance data collected in Halifax, Canada. Given that relatively few patients need UD, a class imbalance problem is addressed by up-sampling methods and prediction models are developed using multiple machine learning methods. The achieved prediction scores are F1-score=0.76, sensitivity=0.76, and specificity=0.97, confirming that models can predict UD with limited patient characteristics.

Abstract
INTRODUCTION Coronary artery and heart valve calcification is a risk factor for cardiovascular death in haemodialysis patients, so calcification prevention should be started as early as possible. Treatment with concomitant calcimimetics and low-dose vitamin D receptor activators (VDRAs) is available, but not enough evidence has been obtained on the efficacy of this regimen, particularly in patients with short dialysis duration. Therefore, this study will evaluate the efficacy and safety of early intervention with upacicalcet, a calcimimetic used to prevent coronary artery calcification in this patient population. METHODS AND ANALYSIS This multicentre, open-label, randomised, parallel-group controlled study will compare an early intervention group, which received upacicalcet and a low-dose VDRA, with a conventional therapy group, which received a VDRA. The primary endpoint is a change in log coronary artery calcium volume score from baseline to 52 weeks. The main inclusion criteria are as follows: (1) age 18 years or older; (2) dialysis is planned or dialysis duration is less than 60 months; (3) intact parathyroid hormone (PTH) >240 pg/mL or whole PTH level>140 pg/mL; (4) serum-corrected calcium≥8.4 mg/dL and (5) Agatston score >30. The main exclusion criteria are as follows: (1) history of parathyroid intervention or fracture in the past 12 weeks; (2) history of myocardial infarction, stroke or leg amputation in the past 12 weeks; (3) history of coronary angioplasty and (4) heart failure of New York Heart Association class III or worse. ETHICS AND DISSEMINATION The study will comply with the Declaration of Helsinki and the Japanese Clinical Trials Act. The study protocol has been approved by the Fujita Health University Certified Review Board (file no. CR22-052). Written informed consent will be obtained from all participants. Study results will be presented in academic meetings and peer-reviewed academic journals. TRIAL REGISTRATION NUMBER jRCTs041220126.

Abstract
BACKGROUND AND AIM Acute kidney injury (AKI) is becoming increasingly prevalent among hospitalized patients and carries a poor prognosis. While new biomarkers show promise in identifying early stages of AKI, accurately predicting severe outcomes such as the need for kidney replacement therapy (KRT) or death remains a challenge. However, blood gas analyses (BGA) can be used to diagnose life-threatening complications associated with AKI. The objective of this study was to assess the role of BGA as a biomarker panel in both emerging and established cases of AKI. METHODS Retrospective observational study examining subjects with newly developed acute kidney injury (AKI). The study will document venous and arterial pH, pCO2, and actual bicarbonate levels upon hospital admission and at the onset of AKI. The primary endpoints include in-hospital mortality, the need for kidney replacement therapy (KRT), and the recovery of kidney function (ROKF). RESULTS A total of 202 individuals were included in the study. Three variables were found to be independent predictors of in-hospital survival: admission arterial pH, arterial pH at acute kidney injury (AKI) onset, and arterial pCO2 at AKI onset. Additionally, venous pCO2 at AKI onset was identified as an independent predictor for the need of kidney replacement therapy (KRT). CONCLUSIONS Our study suggests that blood gas analysis may have a potential role in predicting severe outcome variables in acute kidney injury (AKI). The associated costs are minimal.

Abstract
Patients with end-stage kidney disease (ESKD) have a high symptom-burden and high rates of morbidity and mortality. Despite this, evidence has shown that this patient group does not have timely discussions to plan for deterioration and death, and at the end of life there are unmet palliative care needs. Advance care planning is a process that can help patients share their personal values and preferences for their future care and prepare for declining health. Earlier, more integrated and holistic advance care planning has the potential to improve access to care services, communication, and preparedness for future decision-making and changing circumstances. However, there are many barriers to successful implementation of advance care planning in this population. In this narrative review we discuss the current evidence for advance care planning in patients on dialysis, the data around the barriers to advance care planning implementation, and interventions that have been trialled. The review explores whether the concepts and approaches to advance care planning in this population need to be updated to encompass current and future care. It suggests that a shift from a problem-orientated approach to a goal-orientated approach may lead to better engagement, with more patient-centred and satisfying outcomes.

Abstract
BACKGROUND Caring for hemodialysis patients could be a heavy burden on family caregivers, causing them to become fatigued and decrease their quality of life. This study aimed to investigate whether Jacobson's relaxation can help alleviate the fatigue of family caregivers of hemodialysis patients. METHODS This randomized controlled trial was conducted in 2021. Sixty-six family caregivers of hemodialysis patients were recruited by convenience sampling from a referral hospital in Tehran, Iran, and assigned randomly by coin toss to two groups of experimental (n = 32) and control (n = 34). Caregivers in the experimental group performed Jacobson's relaxation three times a week, each time for 30-45 min, for 30 days. The score and severity of fatigue before, 2 weeks after, and 1 month after the intervention were measured with the Fatigue Severity Scale. Data analysis was performed in the statistics software SPSS using descriptive statistics (frequency, percentage, mean, and standard deviation) and analytic statistics (Independent Samples t-test, Mann-Whitney U test, Chi-Square test, Fisher's exact test, and RM-ANOVA test). The significance level was less than 0.05. RESULTS The fatigue scores of the experimental and control groups were not significantly different before the intervention (4.42 ± 0.42 vs. 4.38 ± 0.42, P = 0.696). However, the experimental group had significantly lower fatigue scores than the control group 2 weeks after the intervention (4.11 ± 0.63 vs. 4.39 ± 0.42, P = 0.036) and 1 month after the intervention (3.5 ± 0.71 vs. 4.4 ± 0.44, P = 0.001). The results also showed a significant drop in the fatigue score of the experimental group after the intervention (P < 0.0001), but no such change in the control group (P = 0.662). CONCLUSION Jacobson's relaxation technique was effective in alleviating the fatigue of family caregivers of hemodialysis patients. Nurses are therefore recommended to promote the technique as a safe and easy method of fatigue management for family caregivers.

Abstract
BACKGROUND People with chronic kidney disease (CKD) treated with dialysis are frequently affected by depression. Psychotherapy has been reported to decrease depressive symptoms in various chronic diseases and is a potential treatment option for depression. We aimed to perform a systematic review and meta-analysis to evaluate the effect of psychotherapy on depression in adults with CKD. METHODS We searched MEDLINE, Embase, Web of Science, and Cochrane for published studies up to October 31, 2023. Two investigators independently reviewed the included studies and extracted relevant data. Randomized controlled trials (RCTs) assessing the impact of interventions that provide psychological, emotional, or social support without the use of pharmacological substances on depressive symptoms in people with CKD were included and summarized. Scores on different tools for depressive assessment and quality of life were pooled. RESULTS A total of 19 RCTs published between 2004 and 2023 were included and analyzed. The weighted mean difference (WMD) for all included studies with regard to depression was - 2.32 (95%CI=-3.83, -0.80, P = 0.003). The WMD for Beck Depression Inventory (BDI) score of depression was - 3.27 (95%CI=-7.81, 1.27, P = 0.158) with significant heterogeneity (I2 = 95.1%). Significant WMD was detected for the Hospital Anxiety and Depression Scale (HADS) tool: WMD=-1.90, 95%CI=-2.91, -0.90, P < 0.001. The WMD for all included studies regarding quality of life was 1.21 (95%CI=-0.51, 2.93, P = 0.168). The WMD for Kidney Disease Quality of Life Short Form (KDQOL-SF) score was 4.55 (95%CI = 0.50, 8.60, P = 0.028). The WMD for SF-36 score was 0.02 (95%CI=-10.33, 10.36, P = 0.998). Significant difference on outcomes of S-PRT scale was observed (WMD = 2.42, 95%CI = 1.07, 3.76, P < 0.001). CONCLUSIONS Psychosocial interventions probably reduce the depression level among CKD patients. Preliminary evidence suggests that psychosocial interventions might be beneficial for the quality of life in CKD patients. Our results provide medical facilities with an evidence-based basis for establishing psychosocial interventions in kidney care settings.

Abstract
Anemia is a frequent and early chronic kidney disease (CKD) complication. Its management is currently based on oral or intravenous iron supplements, erythropoiesis-stimulating agents, and red blood cell transfusions, when the benefits of transfusion outweigh the risks. Anemia in CKD patients is underdiagnosed and undertreated. Current standard of care is associated with challenges and therefore new treatment approaches have been sought. Hypoxia-inducible factor-prolyl-hydroxylase enzyme inhibitors are a new class of orally administered drugs used to treat anemia associated with CKD. Small-molecule hypoxia-inducible factor-prolyl-hydroxylase inhibitors have a novel mechanism of action that activates the hypoxia-inducible factor (oxygen-sensing) pathway resulting in a coordinated erythropoietic response, leading to increased endogenous erythropoietin production, improved iron absorption and transport, and reduced hepcidin. Roxadustat is the first hypoxia-inducible factor-prolyl-hydroxylase inhibitor approved by the European Medicines Agency (EMA) and reimbursed in Italy by the Italian Medicines Agency (AIFA) for the treatment of adult patients with symptomatic CKD-related anemia. This authorization was based on the outcome of a globally-conducted phase 3 clinical trial program comprising eight pivotal multicenter randomized studies. In the absence of up-to-date guidelines, we performed a critical appraisal of the placement and use of roxadustat in this therapeutic context.

Abstract
OBJECTIVES To externally validate the four-variable kidney failure risk equation (KFRE) in the Peruvian population for predicting kidney failure at 2 and 5 years. DESIGN A retrospective cohort study. SETTING 17 primary care centres from the Health's Social Security of Peru. PARTICIPANTS Patients older than 18 years, diagnosed with chronic kidney disease stage 3a-3b-4 and 3b-4, between January 2013 and December 2017. Patients were followed until they developed kidney failure, died, were lost, or ended the study (31 December 2019), whichever came first. PRIMARY AND SECONDARY OUTCOME MEASURES Performance of the KFRE model was assessed based on discrimination and calibration measures considering the competing risk of death. RESULTS We included 7519 patients in stages 3a-4 and 2798 patients in stages 3b-4. The estimated cumulative incidence of kidney failure, accounting for competing event of death, at 2 years and 5 years, was 1.52% and 3.37% in stages 3a-4 and 3.15% and 6.86% in stages 3b-4. KFRE discrimination at 2 and 5 years was high, with time-dependent area under the curve and C-index >0.8 for all populations. Regarding calibration in-the-large, the observed to expected ratio and the calibration intercept indicated that KFRE underestimates the overall risk at 2 years and overestimates it at 5 years in all populations. CONCLUSIONS The four-variable KFRE models have good discrimination but poor calibration in the Peruvian population. The model underestimates the risk of kidney failure in the short term and overestimates it in the long term. Further research should focus on updating or recalibrating the KFRE model to better predict kidney failure in the Peruvian context before recommending its use in clinical practice.

Abstract
BACKGROUND Tertiary hyperparathyroidism describes the autonomous and excessive secretion of parathyroid hormone (PTH) by the parathyroid glands after longstanding secondary hyperparathyroidism in chronic kidney disease. Brown tumors are a sign of uncontrolled hyperparathyroidism. In this case, we have reported a refractory and destructive hyperparathyroidism storm. Also, it presented with atypical onset and unexpected adenoma location. CASE PRESENTATION A 37-year-old man was diagnosed with end-stage kidney disease 22 years ago. He has been undergoing dialysis treatment since that time. Recently, he was admitted to the ophthalmology department due to the unilateral anterior bulging of the right eye and drooping of the eyelid. Magnetic resonance imaging exhibited an extraconal mass lesion located in the right orbital posterior superolateral position. Computerized tomography scans considered expansile bone lesion with peripheral calcification and originating from the sphenoid wing. The bone mass lesion was resected via craniotomy due to the compressive effect. The pathological findings were consistent with brown tumors. Plasma intact PTH level was 4557 pg/mL. The patient informed that he underwent parathyroidectomy and two leg fractures operation in a medical query. Parathyroid scintigraphy determined three distinct foci consistent with adenomas and one of them was in mediastenum. Second parathyroidectomy was recommended to the patient but the patient refused surgery. Despite his medication and dialysis regimen being revised, PTH levels were maintained at higher levels in follow-up. CONCLUSIONS We presented a hyperparathyroidism case that was resistant to all treatments and exhibited all the severe complications in a long-term dialysis patient. Furthermore, this case has revealed the importance and difficulty of secondary hyperparathyroidism management.

Abstract
Chronic kidney disease is a progressive condition that affects more than 10% of the general population worldwide. Hemodialysis is the most common therapeutic option for kidney failure, which develops in around one out of 1000 individuals in the general population. Hemodialysis needs a vascular access to connect to the extracorporeal machine. In the last few years percutaneous endovascular arterio-venous fistula technique has been increasingly employed with very promising results. Several advantages have been demonstrated in comparison to the standard surgical creation of an arteriovenous fistula. The percutaneous endovascular arterio-venous fistula technique requires multidisciplinary team work. In our practice, we have organized a multidisciplinary team that includes nephrologists, play a key role, interventional radiologists, vascular surgeons, anesthesiologists, and dialysis nurses. Procedural outcomes and feedback received from patients and family members are evaluated periodically in order to improve results. Nephrologists are involved in each step of the management of the percutaneous endovascular arterio-venous fistula: selection, mapping, creation, and follow up. Patient empowerment, education and involvement is required at each step. A dedicated training program, involving patients and the caregiver team is therefore needed. Additional research is required to confirm the benefit of the multidisciplinary team management in end-stage kidney disease patients.

Abstract
Advancements in pediatric dialysis generally rely on adaptation of technology originally developed for adults. However, in the last decade, particular attention has been paid to neonatal extracorporeal therapies for acute kidney care, an area in which technology has made giant strides in recent years. Peritoneal dialysis (PD) is the kidney replacement therapy (KRT) of choice in the youngest age group because of its simplicity and effectiveness. However, extracorporeal blood purification provides more rapid clearance of solutes and faster fluid removal. Hemodialysis (HD) and continuous KRT (CKRT) are thus the most used dialysis modalities for pediatric acute kidney injury (AKI) in developed countries. The utilization of extracorporeal dialysis for small children is associated with a series of clinical and technical challenges which have discouraged the use of CKRT in this population. The revolution in the management of AKI in newborns has started recently with the development of new CKRT machines for small infants. These new devices have a small extracorporeal volume that potentially prevents the use of blood to prime lines and dialyzer, allow a better volume control and the use of small-sized catheter without compromising the blood flow amount. Thanks to the development of new dedicated devices, we are currently dealing with a true "scientific revolution" in the management of neonates and infants who require an acute kidney support.

Abstract
BACKGROUND During the COVID-19 pandemic, some continuous kidney replacement therapy (CKRT) initiations were transitioned to telemedicine to improve the timeliness of initiation, and minimize COVID-19 transmission. While telemedicine would appear acceptable for many clinical settings, safety and timeliness of telemedicine CKRT initiation is undescribed. METHODS We conducted a single-center retrospective cohort study of pediatric patients on CKRT from January 2021-September 2022. Information on patient characteristics and CKRT therapy was extracted from the electronic health record. Multidisciplinary team provider attitudes and perspectives were assessed using survey. RESULTS During the study period, there were 101 CKRT circuit initiations in patients not previously receiving CKRT, with 33% (33/101) initiated by telemedicine. There were no differences in patient characteristics, including age, weight at initiation, severity of illness, nor degree of fluid overload between the in-person and telemedicine initiation cohorts. CKRT telemedicine initiations were timelier, occurring on average 3.0 h after decision to initiate therapy compared to 5.8 h for all in-person CKRT starts (p < 0.001) and 5.5 h for night and weekend in-person starts (p < 0.001). Complications did not differ between telemedicine and in-person starts (15% vs. 15%, p = 0.99) and initial circuit life was similar. There were no differences in likelihood of death or duration of CKRT therapy. Telemedicine initiations were widely acceptable to multidisciplinary providers. CONCLUSION In appropriately selected patients, telemedicine initiation of CKRT is a timely and safe option. Further standardization of telemedicine initiation of CKRT should be considered to improve the timely delivery of CKRT and may improve nephrology workforce wellness.

Sakuma H, Ikeda M, Nakao S, Suetsugu R, Matsuki M, Hasebe N, Nakagawa N. Regional variation in pre- dialysis blood pressure and its association with cardiovascular mortality rates in Japanese patients undergoing dialysis. Hypertens Res 2024; 47:102-111. [PMID: 37710034 DOI: 10.1038/s41440-023-01415-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 08/08/2023] [Accepted: 08/15/2023] [Indexed: 09/16/2023]
Abstract
Adequate blood pressure (BP) management poses a significant challenge in improving the prognosis of patients undergoing dialysis. We aimed to investigate the relationship between pre-dialysis systolic blood pressure (SBP) and underlying disease in Japanese patients undergoing dialysis, based on prefectural location, and assess the association between pre-dialysis SBP and cardiovascular disease (CVD) mortality rate. We extracted the basic information of 336,182 patients who were undergoing dialysis in 2021 from the Web-based Analysis of Dialysis Data Archives database. Data on average pre-dialysis SBP were analyzed according to sex, prefectural location, and diabetic status, and the CVD mortality rate for each prefecture was calculated. The mean pre-dialysis SBP of the patients (males, 66.3%; mean age, 69.7 ± 12.5 years) was 151.9 ± 24.7 mmHg. Overall, 133,037 patients had underlying diabetic kidney disease (DKD). The patients with DKD were younger, had a shorter dialysis duration, and a higher pre-dialysis SBP than those with non-DKD comorbidities. The prefecture-based mean pre-dialysis SBP values were all higher than 140 mmHg. At the prefectural level, CVD mortality rate was positively correlated with pre-dialysis SBP (r = 0.3127, p = 0.0324) and diastolic blood pressure (r = 0.3378, p = 0.0202) among female patients. At the prefectural level, pre-dialysis SBP is >140 mmHg in Japanese patients undergoing dialysis, especially in those with DKD. The positive association between pre-dialysis SBP and CVD mortality rate suggests that optimal BP management at the prefectural level may reduce CVD mortality rates. At the prefectural level, pre-dialysis SBP is higher than 140 mmHg in Japanese patients undergoing dialysis, especially higher in those with DKD.

Abstract
Background Chronic kidney disease-associated pruritus (CKD-aP) affects patients on hemodialysis. This study identified hemodialysis patients presumably affected or not affected by CKD-aP and integrated healthcare costs, from the perspective of the Italian administrative healthcare data. Methods Through cross-linkage of Italian administrative healthcare data collected between 2015 and 2017 (accrual period) in the database of Fondazione ReS (Ricerca e Salute), patients undergoing in-hospital/outpatient hemodialysis were selected. Cohorts with and without CKD-aP were created based on the presence/absence of CKD-aP-related treatment (according to common clinical practice and guidelines) supplies and assessed in terms of CKD-aP-related treatments and mean healthcare costs per capita paid by the Italian National Health Service (INHS). Results Of 1,239 people on hemodialysis for ≥2 years, CKD-aP affected 218 patients. Patients with CKD-aP were older and with more comorbidities. During the follow-up year, on average, the INHS spent €37,065 per case, €31,286 per control and € 35,988 per non-CKD-aP subject. High-efficiency dialytic therapies performed to people on hemodialysis with CKD-aP largely weighed on the overall mean annual cost. Conclusions This real-world study identified patients on chronic hemodialysis potentially treated for CKD-aP. Interestingly, high-efficiency dialysis seems the most frequent and expensive choice for the treatment of CKD-aP. The discovery of appropriate and effective treatments for this condition might offer cost offsets.

Abstract
Chronic kidney disease (CKD) imposes a significant medication burden on patients due to the necessity of multiple treatments to slow disease progression, manage coexisting conditions, and address complications. The complex medication regimen, in turn, has implications for clinical and patient-centered outcomes. This umbrella review provides comprehensive evidence on extent of medication nonadherence among adults with CKD, as well as associated risk factors, outcomes, and the effectiveness of interventions by synthesizing evidence from published systematic reviews and/or meta-analyses. We identified 37 works that met our inclusion criteria. These reviews covered various aspects of treatment adherence in people with CKD, which can be categorized into four main themes: (i) prevalence of treatment nonadherence; (ii) factors associated with (non)adherent behaviors; (iii) outcomes associated with treatment (non)adherence; and (iv) interventions to improve treatment adherence or overall self-management practices. Approximately half of the included studies (15/34) focused on interventions aimed at improving medication adherence or overall CKD management, while outcomes associated with medication (non)adherence were relatively underexplored in the literature. The reported prevalence rates of medication nonadherence varied widely among reviews and stages of CKD. The determinants of adherence identified included socioeconomic variables, disease or clinical conditions, and psychosocial factors. Common interventions to improve adherence included nurse-led interventions, pharmaceutical services, and eHealth technologies, which had varying effects on medication adherence or dialysis sessions.

Monitoring of ionized magnesium in hemo dialysis patients: A useful tool to allow a personalized prescription of dialysate composition. Clin Chim Acta 2024; 552:117687. [PMID: 38070668 DOI: 10.1016/j.cca.2023.117687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND AND AIMS The dialysate magnesium (Mg) concentration is a major determinant of Mg balance in hemodialysis. This study aimed to assess the systemic variations of total (tMg) and ionized Mg (iMg) during a dialysis session using acetate or citrate fluids and 0.5 or 0.75 mM Mg. MATERIALS AND METHODS 134 patients in maintenance hemodialysis were assigned to a dialysis session with 4 different dialysates: acetate fluid with 0.5 mM Mg (1) or 0.75 mM Mg (2), citrate fluid with 0.5 mM Mg (3) or 0.75 mM Mg (4). Ionized form was measured by direct ion-selective electrode. RESULTS A Mg loss was observed in both acetate (0.12 and 0.08 mmol/L) and citrate (0.13 and 0.14 mmol/L for tMg and iMg, respectively) fluid groups containing 0.5 mM Mg. The use of acetate and citrate dialysates with 0.75 mM Mg led to a significant median intra-dialytic increase of 0.15 and 0.08 mmol/L for tMg, respectively. A significant augmentation in iMg concentration with acetate (0.11 mmol/L) but not with citrate dialysate (0.02 mmol/L) was observed. CONCLUSION While a dialysate Mg concentration at 0.5 mM leads to a negative balance, increasing the concentration to 0.75 mM significantly raises post-dialysis circulating Mg. Monitoring of iMg should allow a personalized prescription in dialysate Mg.

Abstract
An 18-year-old man underwent allogenic bone marrow transplantation (BMT) for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL). Ph+ALL relapsed 3 months after the first BMT, and the patient underwent a second BMT. However, Ph+ALL relapsed 4 months after the second BMT, and he received a haploidentical peripheral blood stem cell transplantation (haplo-PBSCT) from his father. Molecular complete remission was confirmed 29 days after haplo-PBSCT. However, the patient needed dialysis for end-stage renal disease due to thrombotic microangiopathy 3 years and 2 months after haplo-PBSCT. He received a kidney transplantation from his father 7 years and 10 months after haplo-PBSCT, and got off dialysis after the kidney transplantation. Immunosuppressive therapy with methylprednisolone, tacrolimus, and mycophenolate mofetil was started for kidney transplantation, but the dose of immunosuppressive agents was reduced successfully without rejection soon after kidney transplantation. The patient has maintained long-term remission since the haplo-PBSCT, and his kidney function was restored by the kidney transplantation from his father.

Abstract
Rationale & Objective Almost all patients who receive dialysis experience polypharmacy, but little is known about their experiences with medication or perceptions toward it. In this qualitative study, we aimed to gain insight into dialysis patients' experiences with polypharmacy, the ways they integrate their medication into their daily lives, and the ways it affects their quality of life. Study Design Qualitative study using semistructured interviews. Setting & Participants Patients who received dialysis from 2 Dutch university hospitals. Analytical Approach Interviews were transcribed verbatim and analyzed independently by 2 researchers through thematic content analysis. Results Overall, 28 individuals were interviewed (29% women, mean age 63 ± 16 years, median dialysis vintage 25.5 [interquartile range, 15-48] months, mean daily number of medications 10 ± 3). Important themes were as follows: (1) their own definition of what constitutes "medication," (2) their perception of medication, (3) medication routines and their impact on daily (quality of) life, and (4) interactions with health care professionals and others regarding medication. Participants generally perceived medication as burdensome but less so than dialysis. Medication was accepted as an essential precondition for their health, although participants did not always notice these health benefits directly. Medication routines and other coping mechanisms helped participants reduce the perceived negative effects of medication. In fact, medication increased freedom for some participants. Participants generally had constructive relationships with their physicians when discussing their medication. Limitations Results are context dependent and might therefore not apply directly to other contexts. Conclusions Polypharmacy negatively affected dialysis patients' quality of life, but these effects were overshadowed by the burden of dialysis. The patients' realization that medication is important to their health and effective coping strategies mitigated the negative impact of polypharmacy on their quality of life. Physicians and patients should work together continuously to evaluate the impact of treatments on health and other aspects of patients' daily lives. Plain-Language Summary People receiving dialysis treatment are prescribed a large number of medications (polypharmacy). Polypharmacy is associated with a number of issues, including a lower health-related quality of life. In this study we interviewed patients who received dialysis treatment to understand how they experience polypharmacy in the context of their daily lives. Participants generally perceived medication as burdensome but less so than dialysis and accepted medication as an essential precondition for their health. Medication routines and other coping mechanisms helped participants mitigate the perceived negative effects of medication. In fact, medication led to increased freedom for some participants. Participants had generally constructive relationships with their physicians when discussing their medication but felt that physicians sometimes do not understand them.

Abstract
Drivers towards initiation of kidney replacement therapy in advanced chronic kidney disease include metabolic and fluid derangements, growth, and nutritional status with focus on health optimization. Once initiated, prescription of dialysis is often uniform despite variability in patient characteristics and etiology of kidney failure. Preservation of residual kidney function has been associated with improved outcomes in patients with advanced chronic kidney disease on dialysis. Incremental dialysis is the approach of reducing the dialysis dose by reduction in treatment time, days, or efficiency of clearance. Incremental dialysis has been described in adults at initiation of kidney replacement therapy, to better preserve residual kidney function and meet the individual needs of the patient. Consideration of incremental dialysis in pediatrics may be reasonable in a subset of children with continued emphasis on promotion of growth and development.

Abstract
BACKGROUND Iron overload due to the excessive use of parenteral iron in haemodialysis is now an increasingly recognised clinical issue. Before erythropoiesis-stimulating agents (ESA) were introduced, a specific feature of patients treated by dialysis and having iron overload was that iron levels in the bone marrow were paradoxically low in most of them, despite severe hepatosplenic siderosis. Whether or not this paradox persists in the actual ESA era was unknown until recently, when an autopsy study in 21 patients treated by haemodialysis revealed similarities between liver and bone marrow iron content. The aim of this study was to further explore these recent findings in a cohort of alive patients on dialysis and to analyse the determinants of iron bone marrow. METHODS Liver iron concentration (LIC) and vertebral T2∗ (a surrogate marker of bone marrow iron) were analysed retrospectively in 152 alive patients on dialysis (38.8% female) of whom 47.4% had iron overload by quantitative magnetic resonance imaging (MRI). FINDINGS Vertebral T2∗ differed significantly between patients classified according to liver iron content at MRI: those with mild or moderate and severe liver iron overload had increased vertebral iron content at R2∗ relaxometry MRI (mild: vertebral T2∗ = 9.9 ms (4-24.8); moderate and severe: vertebral T2∗ = 8.5 ms (4.9-22.8)) when compared to patients with normal LIC (vertebral T2∗ = 13.2 ms (6.6-30.5) (p < 0.0001 Kruskal-Wallis test)). INTERPRETATION The paradoxical discrepancy between bone marrow and liver iron-storage compartments observed in the pre-ESA era has disappeared today, as shown by a recent autopsy study and the present study in a cohort of alive patients treated by dialysis. FUNDING None.

Abstract
BACKGROUND/PURPOSE Encapsulating peritoneal sclerosis (EPS) is a rare and potential lethal complication of peritoneal dialysis characterized by bowel obstruction. Surgical enterolysis is the only curative therapy. Currently, there are no tools for predicting postsurgical prognosis. This study aimed to identify a computed tomography (CT) scoring system that could predict mortality after surgery in patients with severe EPS. METHODS This retrospective study enrolled patients with severe EPS who underwent surgical enterolysis in a tertiary referral medical center. The association of CT score with surgical outcomes including mortality, blood loss, and bowel perforation was analyzed. RESULTS Thirty-four patients who underwent 37 procedures were recruited and divided into a survivor and non-survivor group. The survivor group had higher body mass indices (BMIs, 18.1 vs. 16.7 kg/m2, p = 0.035) and lower CT scores (11 vs. 17, p < 0.001) than the non-survivor group. The receiver operating characteristic curve revealed that a CT score of ≥15 could be considered a cutoff point to predict surgical mortality, with an area under the curve of 0.93, sensitivity of 88.9%, and specificity of 82.1%. Compared with the group with CT scores of <15, the group with CT scores of ≥15 had a lower BMI (19.7 vs. 16.2 kg/m2, p = 0.004), higher mortality (4.2% vs. 61.5%, p < 0.001), greater blood loss (50 vs. 400 mL, p = 0.007), and higher incidence of bowel perforation (12.5% vs. 61.5%, p = 0.006). CONCLUSION The CT scoring system could be useful in predicting surgical risk in patients with severe EPS receiving enterolysis.

Abstract
Background Limited data are available regarding the management and outcomes of patients with sepsis-associated acute kidney injury (SA-AKI) requiring dialysis in Sudan. Continuous renal replacement therapy (CRRT) is a highly favored treatment modality in such patients. However, it stays unavailable and expensive treatment in most low-income countries. We aimed to evaluate the use of sustained low-efficiency dialysis (SLED) in the treatment of hemodynamically unstable patients with SA-AKI admitted to the intensive care unit (ICU). Materials and methods A prospective cohort was conducted in Baraha Medical City, Khartoum, Sudan. Patients above 18 years of age, who were admitted to the ICU between January and September 2020 with SA-AKI, and required SLED or CRRT were enrolled. These were followed up till death or discharge from the ICU. They were observed regarding their dialysis tolerance, rate of renal recovery, ICU mortality, and cost of therapy. Data analysis was done using SPSS. Results Fifty-three adults were enrolled. Their mean age was 62 ± 11 years, and 56.6% were males. Thirty-one patients (58.5%) received SLED and 22 (41.5%) underwent CRRT. Patients in the two groups were age and sex matched and showed no significant differences in their comorbid conditions, source of sepsis, sequential organ failure assessment (SOFA) score, and their indications for dialysis (p > 0.05). Patients treated with SLED showed similar dialysis tolerance, rate of renal recovery, length of ICU admission, and risk of death compared to those treated with CRRT (p > 0.05). Moreover, SLED treatments were less expensive than CRRT, and the costs of ICU admission among the SLED group were significantly less (p < 0.001). Conclusion Our study shows that SLED is safe and effective. It is readily available and can be routinely performed in the treatment of hemodynamically unstable patients with SA-AKI at a significantly lower cost.

Abstract
Korean Renal Data System (KORDS) is a nationwide end-stage renal disease (ESRD) registry database operated by the Korean Society of Nephrology (KSN). Diabetes mellitus is currently the leading cause of ESRD in Korea; this article provides an update on the trends and characteristics of diabetic ESRD patients. The KORDS Committee of KSN collects data on dialysis centers and patients through an online registry program. Here, we analyzed the status and trends in characteristics of diabetic chronic kidney disease stage 5D (CKD 5D) patients using data from 2001 to 2021. In 2021, the dialysis adequacy of hemodialysis (HD) was lower in diabetic CKD 5D patients than in nondiabetic CKD 5D patients, while that of peritoneal dialysis (PD) was similar. Diabetic CKD 5D patients had a higher proportion of cardiac and vascular diseases and were more frequently admitted to hospitals than nondiabetic CKD 5D patients, and the leading cause of death was cardiac disease. From 2001 to 2020, diabetic CKD 5D patients had a higher mortality rate than nondiabetic CKD 5D patients, but in 2021 this trend was reversed. Diabetic PD patients had the highest mortality rate over 20 years. The mortality rate of diabetic HD patients was higher than that of nondiabetic HD patients until 2019 but became lower starting in 2020. There was a decreasing trend in mortality rate in diabetic CKD 5D patients, but cardiac and vascular diseases were still prevalent in diabetic CKD 5D patients with frequent admissions to hospitals. More specialized care is needed to improve the clinical outcomes of diabetic CKD 5D patients.

Abstract
AIMS The increasing prevalence of end-stage renal disease (ESRD) in the United States (US) represents a considerable economic burden due to the high cost of dialysis treatment. This review examines data from real-world studies to identify cost drivers and explore areas where dialysis costs could be reduced. METHODS We identified and synthesized evidence published from 2016-2023 reporting direct dialysis costs in adult US patients from a comprehensive literature search of MEDLINE, Embase, and grey literature sources (e.g. US Renal Data System reports). RESULTS Most identified data related to Medicare expenditures. Overall Medicare spending in 2020 was $29B for hemodialysis and $2.8B for peritoneal dialysis (PD). Dialysis costs accounted for almost 80% of total Medicare expenditures on ESRD beneficiaries. Private insurance payers consistently pay more for dialysis; for example, per person per month spending by private insurers on outpatient dialysis was estimated at $10,149 compared with Medicare spending of $3,364. Dialysis costs were higher in specific high-risk patient groups (e.g. type 2 diabetes, hepatitis C). Spending on hemodialysis was higher than on PD, but the gap in spending between PD and hemodialysis is closing. Vascular access costs accounted for a substantial proportion of dialysis costs. LIMITATIONS Insufficient detail in the identified studies, especially related to outpatient costs, limits opportunities to identify key drivers. Differences between the studies in methods of measuring dialysis costs make generalization of these results difficult. CONCLUSIONS These findings indicate that prevention of or delay in progression to ESRD could have considerable cost savings for Medicare and private payers, particularly in patients with high-risk conditions such as type 2 diabetes. More efficient use of resources is needed, including low-cost medication, to improve clinical outcomes and lower overall costs, especially in high-risk groups. Widening access to PD where it is safe and appropriate may help to reduce dialysis costs.

Pediatr Nephrol 2024; 39:291-296. [PMID: 37491518 DOI: 10.1007/s00467-023-06090-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/01/2023] [Accepted: 07/03/2023] [Indexed: 07/27/2023]
Abstract
BACKGROUND Crush syndrome (CS) is a systemic condition resulting from rhabdomyolysis caused by prolonged pressure on muscle tissue. It is estimated that CS will develop in approximately 2-5% of all injuries related to an earthquake, and acute kidney injury (AKI) will develop in approximately 1.5% of all injuries. The present study aimed to present the evaluation of pediatric patients with CS who developed AKI to determine the risk factors that can be determined beforehand for the need for dialysis and to present a new scoring developed for dialysis indication. METHODS Pediatric patients with CS and who underwent dialysis for AKI were included in the study. The study was conducted retrospectively and as single-center data. A renal scoring system that determines the indications for dialysis in patients with CS by parameters of eGFR, creatine phosphokinase (CPK), time under rubble, presence of amputation or fasciotomy, and urine volume was included. RESULTS The mean age was 11.53 ± 4.50 years, and 58.4% of the group were male. Among the 77 patients, 33 (42.8%) underwent kidney replacement therapy (KRT). Renal score, CPK level, and presence of myoglobinuria were determined to be the best markers for KRT indication in pediatric patients with CS (p < 0.01, p = 0.02, and p < 0.01, respectively). CONCLUSIONS We suggest that if a similar disaster occurs in the future, an easy and applicable renal scoring system can contribute to the prognosis by providing appropriate and early treatment for KRT.

Abstract
A male patient in his 70s on periodic haemodialysis complained of dysdialysis several months prior and was diagnosed subsequently with pulmonary hypertension (PH). To confirm this diagnosis, a catheter examination was performed after haemodialysis in the dry state. Pulmonary artery wedge pressure (PAWP), mean pulmonary artery (PA) pressure, cardiac index (CI) and pulmonary vascular resistance (PVR) were 9 mm Hg, 42 mm Hg, 2.63 L/min/m2 and 5.9 WU, respectively. The pathophysiological diagnosis was precapillary PH, which mimicked idiopathic PH. The pulmonary vasodilators were administered in a careful sequential manner. After initiation of therapy, dysdialysis disappeared within a few months, while mean PA pressure, CI and PVR improved to 24 mm Hg, 3.47 L/min/m2 and 2.3 WU, respectively. Although the cause of PH in haemodialysis patients is multifactorial, catheter examination in the dry state is useful for clarifying a patient's haemodynamic state. In a haemodialysis PH patient with precapillary PH, pulmonary vasodilators are an effective treatment option.

Abstract
OBJECTIVES Access related hand ischemia (ARHI) is a rare albeit morbid complication of hemodialysis access creation. Distal radial artery ligation (DRAL) has been described as a strategy to improve perfusion to the hand while maintaining the access. The objective of this study was to report longitudinal outcomes of DRAL for ARHI. METHODS Retrospective cohort study (2015-2021) of all patients who underwent DRAL for ARHI at a tertiary care vascular center. Subjects were identified using the Mass General Brigham clinical data warehouse and data collection was supplemented with chart adjudication. Outcomes captured included 30-day complications and improvement in ARHI-related symptoms at 1 year. RESULTS Thirty-one patients were included. Mean (SD) age was 59.9 (14.5) and 67.7% were male. Wrist radial-cephalic (74.2%) and proximal radial-cephalic (9.7%) configurations were most common. ARHI severity was: 9.7% stage 1 (retrograde flow without symptoms); 38.7% stage 2 (pain during exercise or dialysis); 41.9% stage 3 (pain at rest); and 9.7% stage 4 (tissue loss). High flow was present in 35.5% of patients at baseline with median (IQR) flow of 1670 ml/min (1478-1954). After DRAL, median (IQR) flow reduction in the high flow group was 953 ml/min (645-993); concurrent precision banding was performed in 29% to reduce flow. The 30-day risk of complication was 3.2% (n = 1 access thrombosis). During follow-up, 82.1% showed improvement in symptoms and 3.6% of patients needed an additional procedure for ARHI. Carpal tunnel surgery was required for improvement in 7.1% of patients and was suspected as the culprit of symptoms in 7.1%. CONCLUSION Distal radial artery ligation for ARHI is safe and can improve ischemic symptoms in most patients while salvaging access function. Precision banding can serve as a useful adjunct in high flow accesses. Carpal tunnel syndrome should be considered as part of the differential diagnosis of hand pain in this population.

Metabolic disturbances potentially attributable to clogging during continuous renal replacement therapy. Intensive Care Med Exp 2023; 11:99. [PMID: 38127207 PMCID: PMC10739685 DOI: 10.1186/s40635-023-00581-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 12/12/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Clogging is characterized by a progressive impairment of transmembrane patency in renal replacement devices and occurs due to obstruction of pores by unknown molecules. If citrate-based anti-coagulation is used, clogging can manifest as a metabolic alkalosis accompanied by hypernatremia and hypercalcemia, primarily a consequence of Na3Citrate infusion. An increased incidence of clogging has been observed during the COVID-19 pandemic. However, precise factors contributing to the formation remain uncertain. This investigation aimed to analyze its incidence and assessed time-varying trajectories of associated factors in critically ill patients on continuous renal replacement therapy (CRRT). METHODS In this retrospective, single-center data analysis, we evaluated COVID-19 patients undergoing CRRT and admitted to critical care between March 2020 and December 2021. We assessed the proportional incidence of clogging surrogates in the overall population and subgroups based on the specific CRRT devices employed at our institution, including multiFiltrate (Fresenius Medical Care) and Prismaflex System (Baxter). Moderate and severe clogging were defined as Na > 145 or ≥ 150 mmol/l and HCO3- > 28.0 or ≥ 30 mmol/l, respectively, with a total albumin-corrected calcium > 2.54 mmol/l. A mixed effect model was introduced to investigate factors associated with development of clogging. RESULTS Fifty-three patients with 240 CRRT runs were analyzed. Moderate and severe clogging occurred in 15% (8/53) and 19% (10/53) of patients, respectively. Twenty-seven percent (37/136) of CRRTs conducted with a multiFiltrate device met the criteria for clogging, whereas no clogging could be observed in patients dialyzed with the Prismaflex System. Occurrence of clogging was associated with elevated triglyceride plasma levels at filter start (p = 0.013), amount of enteral nutrition (p = 0.002) and an increasing white blood cell count over time (p = 0.002). CONCLUSIONS Clogging seems to be a frequently observed phenomenon in critically ill COVID-19 patients. The presence of hypertriglyceridemia, combined with systemic inflammation, may facilitate the development of an impermeable secondary membrane within filters, thereby contributing to compromised membrane patency.

Abstract
INTRODUCTION Despite all available evidence regarding increased morbidity and mortality among dialysis patients due to falls and their complications, and an increase in risk factors for falls, relatively little attention has been focused on evidence-based interventions that can reduce falls. We evaluated the effectiveness of fall prevention interventions among dialysis patients. METHODS We searched Ovid-Medline, Ovid-Embase, PubMed, Cumulated Index to Nursing and Allied Health Literature and the Cochrane Central Register of Controlled Trials (Central) from inception to 19 July 2023 for studies that evaluated the effectiveness of fall prevention interventions among dialysis patients. The search, screening and extraction of data followed standardised processes and the methodological quality of studies was independently assessed by two reviewers. Data was analysed using a narrative synthesis approach. RESULTS Of the 18 studies that had full text review, five were eligible. Three studies were performed in the USA and one each in UK and Japan. Four studies were conducted in outpatient hemodialysis centres and one in a hospital-based nephrology unit. Reported sample sizes ranged from 51 to 96 participants per study with a follow-up period of 3 to 35 months. There was moderate-quality evidence that exercises reduce the rate of falls compared to usual care and low to moderate quality of evidence that multifactorial falls prevention interventions reduce the rate of falls. However, treatment effects could not be quantitatively estimated for all interventions due to substantial heterogeneity of included studies. CONCLUSIONS This systematic review reflects that there is insufficient evidence regarding falls prevention strategies specific to dialysis patients. Available data based on low to moderate quality studies, suggest that among dialysis patients, exercises may reduce falls and the effectiveness of multifactorial interventions such as staff and patient education still need to be explored using high-quality prospective studies.

Abstract
Peritoneal dialysis (PD)-associated peritonitis is linked to increased mortality rates and transfer to haemodialysis or PD discontinuation. Rare and emerging pathogens can pose challenges in management. We present the first case of PD peritonitis caused by Elizabethkingia miricola through direct contamination, which was successfully treated with intraperitoneal and oral antibiotics.

Abstract
BACKGROUND Streptococcus pneumoniae-associated hemolytic uremic syndrome (P-HUS) is a rare and severe disease. Only a few reports have been published about eculizumab use in P-HUS. METHODS We analyzed demographic, clinical, and laboratory data of patients with P-HUS from our center. RESULTS The cohort consisted of 4 females and 3 males. All patients had pneumonia. Four were given eculizumab (days 1-3). The eculizumab group required a shorter duration of dialysis and mechanical ventilation (medians 20 vs. 28.5 and 30 vs 38.5 days, respectively) compared with the non-eculizumab group, but this was still much longer than normally reported; the thrombocytopenia resolution was similar in both groups (medians 10 vs. 8 days). Chronic kidney disease (CKD) was correlated with the duration of dialysis and mechanical ventilation duration at 1 year (r = 0.797, P = 0.032 and r = 0.765, P = 0.045) and last follow-up (r = 0.807, P = 0.028 and r = 0.814, P = 0.026, respectively); our scoring system showed even stronger correlations (r = 0.872, P = 0.011 and r = 0.901, P = 0.0057, respectively). The eculizumab group showed slightly better 1-year and last follow-up CKD stage (2.75 vs. 3, P = 0.879 and 2.5 vs. 3.67, P = 0.517). CONCLUSIONS Despite the fact that the eculizumab group showed better outcomes, eculizumab does not seem to improve the course of P-HUS compared with previous reports. Kidney outcomes are strongly correlated with the duration of dialysis and mechanical ventilation duration. A higher resolution version of the Graphical abstract is available as Supplementary information.
