RESUMEN
Background: Very low calorie diets (VLCDs) are an obesity treatment option in the general population, but their efficacy and safety in patients on haemodialysis (HD) is unknown. Methods: Prospective single arm study of VLCD in haemodialysis patients. All participants received 2.5-3.3 MJ/day for 12 weeks. Weekly assessment of VLCD, pre- and post-dialysis weight, inter-dialytic weight gain, and blood electrolytes occurred for the first 4 weeks, then fortnightly for another 8 weeks. Linear mixed models compared the change in weight over time as well as biochemical outcomes including potassium. Results: Twenty-two participants [nine home HD (HHD) and 13 satellite HD (SHD)] enrolled with 19 completing the 12-week intervention. Mean post-dialysis weight declined from 121.1 kg at baseline to 109.9 at week 12 resulting in average decline of 0.88 kg per week (95% C.I. 0.71, 1.05, P < .001) with 12-week mean percentage weight loss9.3% (SD 3.5). Mean post-dialysis body mass index declined from 40.9 kg/m2 at baseline to 37.1 kg/m2 at week 12 (95% C.I. 0.25, 0.35, P < .001). Serum potassium rose from week 1 to 3, stabilized during weeks 4 to 6, and fell from week 8, returning near baseline by week 12. Six of the nine (66.6%) HHD participants and seven of the 13 (70%) SHD participants had at least one episode of hyperkalaemia (K > 6 mmol/l). There were no clinical changes in serum sodium, corrected calcium, or phosphate levels during the study. Conclusion: VLCD with dietitian supervision was effective in producing significant weight reduction, with an acceptable safety profile in patients treated with haemodialysis.
RESUMEN
The relationship between religion and health tends to be framed positively. Religion has been found to act as a coping mechanism and source of support in times of ill health. In this paper, we focus on the disruptive effect of chronic illness on religious practice and cultural engagement. Drawing on interviews with ethnic minority adults with end-stage kidney disease, who also identify as religious, we introduce the concept 'cultural disruption'. While religious practice and belief was found to provide strength and comfort we also found that chronic illness had a disruptive impact on religious and cultural practice that participants attempted to manage. To highlight the potential disruptive effect of chronic illness on religious faith and cultural engagement we identify three elements of cultural disruption-disruption to religious practice, disruption to sense of self and identity and disruption to wellbeing. We conclude by suggesting that understanding and accounting for the potential of cultural disruption when diagnosing, treating and supporting people with chronic illness offers an alternative entry point to the life-worlds of patients who identify as religious and the things that are important to them.
RESUMEN
Automated insulin delivery (AID) in people with type 1 diabetes (pwT1D) and end-stage kidney disease (ESKD) on haemodialysis (HD) has not been reported previously. We describe practical considerations and our findings in four pwT1D on HD for ESKD where AID was safely implemented, with significant improvements in time in range.
RESUMEN
BACKGROUND: Catheter related thrombosis is a common complication of tunnelled central venous catheter (TCVC) usage. There are concerns that TCVC removal could dislodge a thrombus to cause pulmonary thromboembolism (PE). The incidence of PE following TCVC removal is unclear and so the aim of this study was to investigate the incidence of PE and whether it is high enough to warrant screening with ultrasound with a view to systemic anticoagulation prior to TCVC removal. METHODS: 1102 consecutive TCVC removals without ultrasound and systemic anticoagulation were included in this retrospective study. Data were extracted from electronic health records. Measures to identify PE events included: deaths, computed tomography pulmonary angiogram (CT-PA), isotope lung perfusion scans and D-dimers blood tests within 7 days of removal. RESULTS: Of the 1102 TCVC removals, the mean age of patients was 56.9 years and 57.3% were male. The primary renal diagnosis for 24.5% of patients was diabetic nephropathy. There were seven deaths following removal, none of which had PE as a contributing cause on review of their clinical history and death certificates. Five CT-PAs and one isotope lung perfusion scan were carried out in the 7 days after TCVC removal and none had a positive finding of PE. Three patient had D-dimers measured in blood within 7 days and none of these patients were subsequently diagnosed with PE. CONCLUSIONS: There was no evidence of fatal or non-fatal PE's occurring in the 7 days following TCVC removal. This would support the practice of removing TCVCs without the need for ultrasound screening and without a period of systemic anticoagulation.
RESUMEN
AIM: This study aims to explore the experiences of individuals with chronic kidney disease (CKD) undergoing haemodialysis and their caregivers, focusing on the disease's impact and the treatment process. BACKGROUND: In Sri Lanka, CKD is a growing health concern, particularly affecting farming communities and contributing to the strain on the biomedical healthcare system. Despite increasing awareness of CKD's physical implications, its psychosocial impact remains underexplored. This study seeks to fill this gap, aiming to inform culturally sensitive interventions and improve the healthcare system's responsiveness to the unique needs of Sinhala Buddhist individuals with CKD and their caregivers. DESIGN: An exploratory qualitative study. METHOD: Semistructured interviews were conducted with 10 individuals undergoing haemodialysis and 5 caregivers at a dialysis unit. The interviews were audio-recorded, transcribed and analysed using conventional qualitative content analysis. FINDINGS: The analysis revealed three interrelated main themes: (1) impact on standard of living (quality of life), (2) coping strategies and (3) medical experience, with a notable influence of traditional beliefs and practices. CONCLUSION: The findings highlight the need for a holistic approach to CKD management that integrates physical, emotional, psychological and social aspects, considering the significant role of traditional influences. Further research is essential to develop effective interventions that can enhance the quality of life for CKD. PATIENT OR PUBLIC CONTRIBUTION: The lived experiences of Sinhala Buddhist individuals with CKD and their caregivers served as a cornerstone, providing profound insights into the impact of the condition on their lives. Throughout the study, these participants played an instrumental role in refining the research's cultural sensitivity and relevance. Their engagement extended beyond the data collection phase to encompass feedback sessions, where they actively shared their perspectives. This ongoing collaboration ensured the study's depth and applicability to real-world experiences. By actively involving those directly affected by CKD, this collaborative approach safeguards that the study remains rooted in their voices and addresses their unique needs. REPORTING METHOD: This study adhered to relevant EQUATOR guidelines (the COREQ checklist). TRIAL REGISTRATION: This study is not a clinical trial, and thus, registration is not applicable.

INTRODUCTION: Intra-dialytic hypotension (IDH) remains the commonest problem associated with routine haemodialysis treatments. Fluid shifts from intracellular(ICW) and extracellular(ECW) compartments to refill plasma volume during haemodialysis with ultrafiltration. METHODS: We studied the effect of relative changes in ICW and ECW indifferent body segments using multifrequency segmental bioimpedance during haemodialysis and IDH episodes. RESULTS: Of 42 haemodialysis patients,16 patients (38.1%) developed IDH within the first hour of dialysis. Patients with and without early IDH were well-matched for demographics and starting bioimpedance measurements. However, after 60 min, the relative change in in ECW/ICW ratio between the non-fistula arm and leg was significantly different for the early IDH group median -1.07 (-3.33 to 0.8) versus 0.61 (-0.78 to 1.8), p < 0.05, whereas there no differences in ultrafiltration rate, relative blood volume monitoring or on-line clearance. CONCLUSION: Monitoring serial changes in fluid status in different body compartments with bioimpedance may potentially prevent IDH in the future.
RESUMEN
BACKGROUND: Sexual dysfunction is common for adults receiving chronic haemodialysis; however, renal nurses seldom discuss this topic with patients. OBJECTIVES: This study aimed to identify renal nurses' attitudes towards providing sexual healthcare and to determine their confidence in discussing sexual dysfunction with adults who are receiving haemodialysis. DESIGN: An online cross-sectional study. PARTICIPANTS: Renal nurses across Australia and New Zealand (n = 65) who were members of the Renal Society of Australasia provided direct care to adults receiving haemodialysis. MEASUREMENTS: Two questionnaires measuring (1) the frequency of sexual health discussions, levels of knowledge and competence, barriers to discussing sexual dysfunction and views on accountability (Van Ek survey) and (2) communication, practical knowledge, and attitude (sexual health educator for professionals scale) were used. Demographic characteristics were also collected. RESULTS: Most participants were females (60%) with postgraduate qualifications (61.4%). The average nephrology nursing experience was 13.10 ± 9.14 years. Most renal nurses identified as having positive attitudes (77.2%) about providing sexual healthcare and were confident in communicating with patients about sexual concerns (42.9%), although many nurses (64.35%) rarely did so. Less than one-half (48.6%) indicated feeling competent to discuss sexual dysfunction, and less than one-third (30%) had sufficient knowledge about sexual dysfunction. Barriers were lack of practical training (74.2%) and insufficient time (57.1%). Younger nurses (≤45 years old) and male nurses were significantly more confident in discussing sexual health matters. CONCLUSIONS: Overall, renal nurses had positive attitudes towards discussing sexual health concerns with patients however they rarely did so.
RESUMEN
Background: Depressive disorder is common among haemodialysis patients. The purpose of this study was to explore approaches to diagnosing depression in the context of a real-life setting, with the view of creating practical recommendations. It also aimed to evaluate the prevalence of depression and dementia. Methods: We conducted a cross-sectional study in two Dialysis Centres in Poland. Cognitive functions were evaluated using Mini-Mental State Examination (MMSE). The screening for depressive symptoms was assessed using Beck Depression Inventory II (BDI-II). The diagnosis of major depressive disorder was confirmed by a psychiatrist using Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). Sociodemographic and clinical data were also collected. Results: Initially, 136 patients agreed to participate in the study. Dementia was found in 13% of the study group. Sixty-two patients did not agree to perform all the proposed tests and were not included in the analysis, which eventually consisted of 70 patients. According to BDI-II, depressive symptoms were present in 35.7% of patients, while the diagnosis of major depressive disorder (MDD) was confirmed by the psychiatrist in 25.7%. According to the ROC analysis the optimal cut-off score for diagnosing MDD using BDI-II was ≥13 points. Conclusions: This study suggests that the regular screening for depressive symptoms, followed by a psychiatric consultation in selected patients, might improve diagnosing depression with the goal of achieving a higher quality of life and a lower mortality rate. It may also be a cost-effective model for the management of depression among the haemodialysis population.
RESUMEN
INTRODUCTION/AIMS/OBJECTIVE: Inadequate nutritional intake in haemodialysis (HD) patients increases the risk of muscle wasting, nutrient deficiencies, leading to an increased risk of additional morbidity and mortality. We aimed to assess nutritional intake on the dialysis day and nondialysis day (NDD) of patients established on HD. METHODS: We employed a 2-day dietary record, one on the day of dialysis and one on the NDD, and then determined nutritional intake using the Nutritics software. Muscle strength was assessed by hand grip strength, and the body composition was determined using multifrequency bioelectrical impedance recorded postdialysis. RESULTS: We recruited 51 established HD patients dialysing between May 2022 and July 2022, of mean age 60 ± 15 years, 52.9% male, and 51% diabetic. Only 25% achieved the calorie and protein intake recommended by Kidney Disease Outcomes Quality Initiative. Most patients had inadequate consumption of fiber (96%), calcium (86%), iron (80%), zinc (82%), selenium (92%), folate (82%), vitamin A (88%), and (100%) vitamin D. On the other hand, the great majority followed the restriction guidelines for potassium (96%), phosphorus (86%), and sodium (84%), respectively. However, consumption was greater for potassium (P = .007), phosphorus (P = .015), and zinc (P = .032) on NDDs versus dialysis days, but there was no difference in protein or calorie intake between days. CONCLUSION: Our results suggest that many of our HD patients do not achieve the recommended nutritional targets. Patient compliance with restricting sodium, potassium, and phosphate limits protein and calorie intake. HD patients are at increased risk of sarcopenia, so failure to achieve dietary protein intake will further increase this risk.
RESUMEN
BACKGROUND: Fatigue among patients with end-stage kidney disease (ESKD) receiving haemodialysis imposes a substantial burden on patients' quality of life and expected treatment outcomes. This study explores the perspective on ESKD-related fatigue and contributing factors among Omani patients receiving haemodialysis. METHODS: An exploratory qualitative design was used. Participants (N = 25) were recruited from two Omani haemodialysis centres, and data were collected through semi-structured interviews, which were transcribed and analysed using a thematic analysis approach. NVivo 11 is used to manage qualitative data and create memos, nodes, and codes. RESULTS: Findings highlighted three themes: (i)"Inevitability of fatigue," (ii)"Contributors to physical fatigue," and (iii)"Contributors to mental fatigue." Theme one alluded to the inevitability of fatigue and the unique experience encountered by patients. Theme two addressed the physical fatigue associated with ESKD-related factors, such as chronically low haemoglobin levels, and the exhausting impact caused by the frequency and travelling distance for treatment sessions. Theme three, mental fatigue, was notably driven by heightened emotional disturbance, encompassing frustration, guilt, anxiety, and distress, that in turn impacted family interactions, frequently triggering anger and remorse. Moreover, mental fatigue is a result of disturbances in expressing physical sexuality in marriage, as physical fatigue was found to be a significant contributor to unsatisfactory sexual experiences and, thus, straining the relationships between couples. CONCLUSIONS: This study offers an explanation of fatigue among Omani patients with ESKD who are receiving haemodialysis. The study emphasises close links between physiological change, the haemodialysis process, and mental tiredness, together with their contribution to supporting the need for a holistic approach and care strategies in managing these patients and promoting patient and family well-being.

BACKGROUND: The prevalence of pre-frailty is notably high among maintenance hemodialysis (MHD) patients. Pre-frailty, an early and reversible condition between non-frailty and frailty, can lead to adverse outcomes such as increased unplanned hospital admissions and a higher risk of other chronic diseases. Early identification and intervention of pre-frailty in MHD patients are crucial. This study aimed to establish a simple and effective model for screening and identifying MHD patients at high risk of pre-frailty by using 50 kHz-Whole Body Phase Angle (PhA) measured by bioelectrical impedance analysis (BIA), hand grip strength (HGS), the Five-Times-Sit-to-Stand Test (FTSST), and laboratory parameters, with a specific focus on gender differences. METHODS: This prospective cross-sectional study was conducted from September to December 2023 at the Wenjiang Hemodialysis Center in the Department of Nephrology, West China Hospital, Sichuan University, Chengdu, China. A total of 244 MHD patients, including 130 males and 114 females, were enrolled, comprising 128 non-frail and 116 pre-frail individuals. Data were collected prospectively, including demographic information, physical measurements, and laboratory test results. All participants provided informed consent before enrollment. The FRAIL scale (FS) was used to assess pre-frailty in MHD patients. Grip strength was measured using an electronic grip strength tester, physical function was assessed using the Five-Times-Sit-to-Stand Test, and whole-body phase angle was measured using the InBody S10 device. RESULTS: A total of 244 MHD patients with a mean age of 53.75 ± 0.90 years were enrolled, including 130 males with a mean age of 54.12 ± 1.26 years and 114 females with a mean age of 53.32 ± 1.29 years. ROC curve analysis showed that in male patients, the AUC of PhA for predicting pre-frailty was 0.919, with a sensitivity of 94.5% and specificity of 91.3%, and a cutoff value of 6.05°; in female patients, the AUC of PhA was 0.870, with a sensitivity of 70.5% and specificity of 90.6%, and a cutoff value of 5.25°. The AUC of FTSST for screening pre-frailty in male patients was 0.827, with a sensitivity of 62.3% and specificity of 96.2%, and a cutoff value of 12.95 s; in female patients, the AUC of FTSST was 0.784, with a sensitivity of 67.3% and specificity of 84.0%, and a cutoff value of 12.95 s. Additionally, in male patients, the combination of PhA and FTSST resulted in an AUC of 0.930, with a sensitivity of 96.4% and specificity of 81.3%; in female patients, the AUC was 0.911, with a sensitivity of 78.7% and specificity of 92.5%. CONCLUSION: PhA measured by BIA, in combination with the Five-Times-Sit-to-Stand Test, serves as an effective screening tool and predictor of pre-frailty in MHD patients. The combination of PhA and FTSST shows enhanced diagnostic value in female patients, while PhA alone is sufficient for predicting pre-frailty in male patients.

Background: The use of diuretics in patients on haemodialysis (HD) is thought to maintain diuresis. However, this assumption and the optimal dose are based on little scientific evidence, and associations with clinical outcomes are unclear. Methods: We reported international variations in diuretic use and loop diuretic dose across 27 759 HD patients with dialysis vintage <1 year in the Dialysis Outcomes and Practice Patterns Study phases 2-5 (2002-2015), a prospective cohort study. Doses of torsemide (4:1) and bumetanide (80:1) were converted to oral furosemide-equivalent doses. Adjusted Cox, logistic and linear regressions were used to investigate the association of diuretic use and dose with outcomes. Results: Diuretic utilization varied widely by country at vintage <3 months, ranging from >80% in Germany and Sweden to <35% in the USA, at a median dose ranging from 400-500 mg/day in Germany and Sweden to <100 mg/day in Japan and the USA. Neither diuretic use nor higher doses were associated with a lower risk of all-cause mortality, a higher risk of hospitalization for fracture or elevated parathyroid hormone levels, but the prescription of higher doses (>200 mg/day) was associated with a higher risk of all-cause hospitalization. Conclusions: Substantial international differences exist in diuretic prescriptions, with use and doses much higher in some European countries than the USA. The prescription and higher doses of loop diuretics was not associated with improved outcomes.
RESUMEN
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.
RESUMEN
AIM: The effectiveness of the coronavirus disease (COVID-19) vaccine in Japanese patients undergoing haemodialysis has previously not been evaluated on a large scale. We analyzed data from the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR), covering nearly all Japanese patients undergoing dialysis (~95% coverage), to examine the association between COVID-19 vaccination and infection or mortality. METHODS: We used data from the JRDR end-of-year surveys conducted in 2020 and 2021, including information on the COVID-19 vaccination and infection months. COVID-19 infection incidence and its associated mortality rates based on vaccination status (time updated) and odds ratio (OR) (vaccinated vs. unvaccinated) were estimated monthly from April 2021, when vaccination commenced in Japan. RESULTS: COVID-19 infection analysis included 228 865 patients (215 941 vaccinated and 12 924 unvaccinated patients at the end of 2021). The age- and sex-adjusted ORs (aORs) were significantly lower in August, September, October and November 2021, especially in September (aOR [95% confidence interval (CI)]: 0.25 [0.18-0.36]). Additional adjustments for past medical history and laboratory results rarely affected these results. Similarly, in the COVID-19-related mortality analysis with 228 731 patients, including 216 781 vaccinated and 11 950 unvaccinated at the end of 2021, COVID-19-related mortality risk was significantly lower in the vaccinated group in August, September, October and November (aOR [95% CI]: August, 0.32 [0.12-0.84], September, 0.04 [0.01-0.11]; October, 0.10 [0.01-0.81]; November, 0.05 [0.00-0.79]). CONCLUSION: In Japanese patients undergoing haemodialysis, the first or second COVID-19 vaccine dose was significantly associated with decreased COVID-19 infection and mortality rates, suggesting its effectiveness in this population.
RESUMEN
Background: Frailty, characterized by vulnerability, reduced reserves and increased susceptibility to severe events, is a significant concern in chronic haemodialysis (HD) patients. Sarcopenia, corresponding to the progressive loss of muscle mass and strength, may contribute to frailty by reducing functional capacity, mobility and autonomy. However, consensus lacks on the optimal bedside frailty index for chronic HD patients. This study investigated the influence of frailty on chronic HD patient survival and explored the associated factors. Methods: A total of 135 patients were enrolled from January to April 2019 and then followed up prospectively until April 2022. At inclusion, frailty was assessed by the Timed Up and Go (TUG) and Short Physical Performance Battery (SPPB) tests including gait speed, standing balance and lower limb muscle strength. Results: From a total of 114 prevalent chronic HD patients (66% men, age 67.6 ± 15.1 years), 30 died during the follow-up period of 23.7 months (range 16.8-34.3). Deceased patients were older, had more comorbidities and a higher sarcopenia prevalence (P < .05). The TUG and SPPB test scores were significantly reduced in patients who had died [SPPB total score: 7.2 ± 3.3 versus 9.4 ± 2.5; TUG time 8.7 ± 5.8 versus 13.8 ± 10.5 (P < .05)]. Multivariate analysis showed that a higher SPPB score (total value >9) was associated with a lower mortality risk [hazard ratio 0.83 (95% confidence interval 0.74-0.92); P < .03). Each component of the SPPB test was also associated with mortality in univariate analysis, but only the SPPB balance test remained protective against mortality in multivariate analysis. Older age, lower handgrip strength and lower protein catabolic rate were associated with SPPB total scores <9, SPPB balance score and TUG time >10 s. Conclusions: Screening for frailty is crucial in chronic HD patients, and incorporating SPPB, especially the balance test, provides valuable insights. Diminished muscle strength and inadequate protein intake negatively influence the SPPB score and balance in chronic HD patients. Effective identification and management of frailty can therefore improve outcomes. CLINICAL TRIAL REGISTRATION ClinicalTrialsgov: NCT03845452.
RESUMEN
Background: Patients with kidney failure treated with maintenance haemodialysis (HD) require appropriate small molecule clearance. Historically, a component of measuring 'dialysis adequacy' has been quantified using urea kinetic modelling that is dependent on the HD prescription. However, the impact of dialysate flow rate on urea clearance remains poorly described in vivo and its influence on other patient-important outcomes of adequacy is uncertain. Methods: We searched Embase, MEDLINE and the Cochrane Library from inception until April 2022 for randomized controlled trials and observational trials comparing a higher dialysate flow rate (800 ml/min) and lower dialysate flow rate (300 ml/min) with a standard dialysis flow rate (500 ml/min) in adults (age ≥18 years) treated with maintenance HD (>90 consecutive days). We conducted a random effects meta-analysis to estimate the pooled mean difference in dialysis adequacy as measured by Kt/V or urea reduction ratio (URR). Results: A total of 3118 studies were identified. Of those, nine met eligibility criteria and four were included in the meta-analysis. A higher dialysate flow rate (800 ml/min) increased single-pool Kt/V by 0.08 [95% confidence interval (CI) 0.05-0.10, P < .00001] and URR by 3.38 (95% CI 1.97-4.78, P < .00001) compared with a dialysate flow rate of 500 ml/min. Clinically relevant outcomes including symptoms, cognition, physical function and mortality were lacking and studies were generally at a moderate risk of bias due to issues with randomization sequence generation, allocation concealment and blinding. Conclusion: A higher dialysate flow increased urea-based markers of dialysis adequacy. Additional high-quality research is needed to determine the clinical, economic and environmental impacts of higher dialysate flow rates.
RESUMEN
Background: Risk prediction in haemodialysis (HD) patients is challenging due to the impact of the dialysis regime on the patient's volume status and the complex interplay with cardiac function, comorbidities and hypertension. Cardiac function as a key predictor of cardiovascular (CV) mortality in HD patients is challenging to assess in daily routine. Thus the aim of this study was to investigate the association of a novel, non-invasive relative index of systolic function with mortality and to assess its interplay with volume removal. Methods: A total of 558 (373 male/185 female) HD patients with a median age of 66 years were included in this analysis. They underwent 24-hour ambulatory blood pressure monitoring, including wave intensity analysis [i.e. S:D ratio (SDR)]. All-cause and CV mortality served as endpoints and multivariate proportional hazards models were used for risk prediction. Intradialytic changes were analysed in tertiles according to ultrafiltration volume. During a follow-up of 37.8 months, 193 patients died (92 due to CV reasons). Results: The SDR was significantly associated with all-cause {univariate hazard ratio [HR] 1.36 [95% confidence interval (CI) 1.20-1.54], P < .001} and CV [univariate HR 1.41 (95% CI 1.20-1.67), P < .001] mortality. The associations remained significant in multivariate analysis accounting for possible confounders. Changes in the SDR from pre-/early- to post-dialytic averages were significantly different for the three ultrafiltration volume groups. Conclusion: This study provides well-powered evidence for the independent association of a novel index of systolic function with mortality. Furthermore, it revealed a significant association between intradialytic changes of the measure and intradialytic volume removal.
RESUMEN
BACKGROUND: Intestinal necrosis in uremic patients has been reported but is rare. CASE PRESENTATION: A 56-year-old male patient who underwent long-term regular haemodialysis was admitted to the hospital due to involuntary shaking of the limbs and nonsense speech. The patient's symptoms improved after continuous blood purification under heparin anticoagulation, rehydration, sedation, and correction of electrolyte disturbances. However, the patient experienced a sudden onset of abdominal pain and a rapid decrease in blood pressure; high-dose norepinephrine were required to maintain his blood pressure. A plain abdominal radiograph performed at bedside showed intestinal dilation. Colonoscopy revealed inflammation and oedema of the entire colon, with purulent secretions and multiple areas of patchy necrosis. The cause of intestinal ischaemia was not clear. CONCLUSIONS: Although rare, previous causes of uremic colitis have been reported. As the patient developed abdominal pain before the onset of shock and the necrosis was seen on colonoscopy, we suspect that this is a case of fulminant uremic colitis.

AIM: To describe how clinicians provide culturally responsive care to culturally diverse people with kidney failure in haemodialysis centres. BACKGROUND: Culturally diverse individuals receiving in-centre maintenance haemodialysis have unique cultural needs. Unmet cultural needs can impair and profoundly affect their experiences. Given culturally responsive care has the potential to enhance the experiences of culturally diverse people, it is vital to understand how clinicians provide culturally responsive care. METHOD: A scoping review was undertaken using Arksey and OMalleys framework. Five databases: Medline and CINAHL Complete (EBSCO), PsycINFO, Embase (OVID) and ProQuest Theses and Dissertation databases were searched for research literature published in English between 1990 and 2023. Narrative synthesis was used to synthesise the data. RESULTS: From the 17,271 records screened, 17 papers reporting 14 studies met the inclusion criteria. Narrative synthesis revealed two themes: (i) communication enablers and barriers including linguistic differences, professional and lay interpreter use; and (ii) the importance of culture, which encompassed acknowledging cultural priorities, accommodating cultural food preferences and access to cultural training. CONCLUSION: While competing priorities associated with haemodialysis may be a challenge for clinicians, recognising the significance of cultural care needs and accommodating them in care is important. Demonstrating respect towards cultural diversity and providing person-centred care by facilitating the unique cultural needs of people with kidney failure in haemodialysis is imperative. RELEVANCE TO CLINICAL PRACTICE: Culturally responsive care is complex and multidimensional. Individuals' cultural care needs should be acknowledged, respected, and accommodated in care. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution. The study protocol was registered in the Open Science Framework. https://osf.io/uv8g3.
RESUMEN
BACKGROUND: Engagement and partnership with consumers and communities throughout research processes produces high quality research meeting community needs and promoting translation of research into improved policy and practice. Partnership is critical in research involving Aboriginal and/or Torres Strait Islander people (First Nations Peoples) to ensure cultural safety. We present lessons from the design, implementation and progress of the National Health and Medical Research Council funded INtravenous iron polymaltose for First Nations Australian patients with high FERRitin levels on hemodialysis (INFERR) clinical trial. MAIN BODY: The trial was designed to understand the benefits and harms of iron therapy in First Nations Australians on haemodialysis with anaemia and hyperferritinaemia. The lack of evidence for treatment was discussed with patients who were potential participants. A key element ensuring safe conduct of the INFERR trial was the establishment of the Indigenous Reference Groups (IRGs) comprising of dialysis patients based in the Top End of Australia and Central Australia. Two IRGs were needed based on advice from First Nations communities and researchers/academics on the project regarding local cultural differences and approaches to trial conduct. The IRGs underpin culturally safe trial conduct by providing input into study materials and translating study findings into effective messages and policies for First Nations dialysis patients. Throughout the trial conduct, the IRGs' role has developed to provide key mechanisms for advice and guidance regarding research conduct both in this study and more broadly. Support provided to the IRGs by trial First Nations Research Officers and independent First Nations researchers/academics who simplify research concepts is critical. The IRGs have developed feedback documents and processes to participants, stakeholders, and the renal units. They guarantee culturally safe advice for embedding findings from the trial into clinical practice guidelines ensuring evidence-based approaches in managing anaemia in haemodialysis patients with hyperferritinaemia. CONCLUSION: Active consumer and community partnership is critical in research conduct to ensure research impact. Strong partnership with consumers in the INFERR clinical trial has demonstrated that First Nations Consumers will engage in research they understand, that addresses health priorities for them and where they feel respected, listened to, and empowered to achieve change.
In this paper, we present the importance of actively involving consumers in the planning, implementation and conduct of research using the example of a clinical trial among Aboriginal and/or Torres Strait Australians (First Nations Australians) who have kidney disease and are currently receiving haemodialysis. The study assesses how safe and effective it is for people on dialysis to receive iron given through the vein during dialysis when they have anaemia and high levels of a blood test called ferritin, a test used routinely to measure iron levels. Two consumer reference groups of First Nations patients on dialysis, one based in the Top End of Australia and the other based in Central Australia, are supported by First Nations Research Officers and Research Academics to make sure that the research is performed in a way that involves, respects and values First Nations participation, culture, and knowledge. Active consumer and community partnership in this study has supported robust research governance processes which we believe are crucial for knowledge translation to have a positive impact for patients.
