Depression and cognitive impairment are the most common complications of patients on hemodialysis. The objective of this study is to identify contributing factors to depression and cognitive impairment in hemodialysis patients. This is a cross-sectional study involving 110 hemodialysis patients in Hospital Kuala Lumpur. The samples were recruited through universal sampling. Patients were assessed with the Beck Depression Inventory and Montreal Cognitive Assessment. This study found that 18.2% of patients had depression, and 48.2% had cognitive impairment. Factors associated with depression were unmarried status, low education level, and cognitive impairment. Factors associated with cognitive impairment were low education level, depression, and unemployment. Keywords: hemodialysis, depression, cognitive, ESRD eISSN: 2398-4287© 2020. The Authors.

The high frequency of cognitive impairment in individuals on hemodialysis is well characterized. In-center hemodialysis patients are disproportionately affected by cognitive impairment compared with other dialysis populations, identifying hemodialysis itself as a possible factor. The pathophysiology of cognitive impairment has multiple components, but vascular-mediated cerebral injury appears to contribute based on studies demonstrating increased cerebral ischemic lesions and atrophy in brain imaging of patients on hemodialysis. Patients on hemodialysis may be at increased risk for cerebral ischemic injury disease due to vasculopathy associated with ESKD and from their comorbid diseases, such as hypertension and diabetes. This review focuses on the intradialytic cerebral hypoperfusion that can occur during routine hemodialysis due to the circulatory stress of hemodialysis. This includes a review of current methods used to monitor intradialytic cerebral perfusion and the structural and functional cognitive outcomes that have been associated with changes in intradialytic cerebral perfusion. Monitoring of intradialytic cerebral perfusion may become clinically relevant as nephrologists try to avoid the cognitive complications seen with hemodialysis. Identifying the appropriate methods to assess risk for cerebral ischemic injury and the relationship of intradialytic cerebral hypoperfusion to cognitive outcomes will help inform the decision to use intradialytic cerebral perfusion monitoring in the clinical setting as part of a strategy to prevent cognitive decline.

AbstractBackgroundCognitive impairment is prevalent but still poorly diagnosed in hemodialysis adults, mainly because of the impracticality of current tools. This study examined whether remotely monitoring mobility performance can help identifying digital measures of cognitive impairment in hemodialysis patients.MethodsSixty-nine hemodialysis patients (age=64.1±8.1years, body mass index=31.7±7.6kg/m2) were recruited. According to the Mini-Mental State Exam, 44 (64%) were determined as cognitive-intact, and 25 (36%) as cognitive-impaired. Mobility performance, including cumulated posture duration (sitting, lying, standing, and walking), daily walking performance (step and unbroken walking bout), as well as postural-transition (daily number and average duration), were measured using a validated pendant-sensor for a continuous period of 24-hour during a non-dialysis day. Motor capacity was quantified by assessing standing balance and gait performance under single-task and dual-task conditions.ResultsNo between-group difference was observed for the motor capacity. However, the mobility performance was different between groups. The cognitive-impaired group spent significantly higher percentage of time in sitting and lying (Cohens effect size d=0.78, p=0.005) but took significantly less daily steps (d=0.69, p=0.015) than the cognitive-intact group. The largest effect of reduction in number of postural-transition was observed in walk-to-sit transition (d=0.65, p=0.020). Regression models based on demographics, addition of daily walking performance, and addition of other mobility performance metrics, led to area-under-curves of 0.76, 0.78, and 0.93, respectively, for discriminating cognitive-impaired cases.ConclusionsThis study suggests that mobility performance metrics could be served as potential digital biomarkers of cognitive impairment among HD patients. It also highlights the additional value of measuring cumulated posture duration and postural-transition to improve the detection of cognitive impairment. Future studies need to examine potential benefits of mobility performance metrics for early diagnosis of cognitive impairment/dementia and timely intervention.

Background: Pain and stress of hemodialysis are experienced by more than 50% of patients who are suffering from renal disease; hence decreasing a part of these adverse effects can be effective on individual’s long term coping with hemodialysis. The current study was done to determine the effect of warm footbath with vibration on arteriovenous fistula puncture-related pain in hemodialysis patients.Methods: This clinical trial was conducted on 31 hemodialysis patients in 2014. The patients were selected by simple random sampling method and placed in one group. First, the pain intensity of all patients was measured in the six frequent hemodialysis sessions without any intervention (control method). After two weeks, the intervention of warm footbath with vibration was done on all patients and the pain intensity was measured for six frequent hemodialysis sessions (intervention method). The patients were received 40±2 °C footbath with vibration by foot massage spa machine for ten minutes; then, fistula needles were placed and the pain intensity was assessed by using a numerical rating scale. Data were analyzed by ANOVA and T test.Results: The study group had contained 20 males (64.5%), 11 females (35.5%), with an average age of 44.16±14.85 and a range of 18 to 65 years old, which shows that the pain intensity of the warm footbath with vibration method was lower than the control method (P< 0.05).Conclusions: Warm footbath with vibration can be used as an effective palliative method to reduce pain of hemodialysis patients.

Abstract Background and Aims: Chronic kidney disease (CKD) and cognitive impairment (CI) are two major health problems in an aging population, and both carry out negative prognostic implications. Prevalence in general population appears to be around 22.2% and recent analysis indicates that CI and frailty can be more prevalent in individuals undergoing hemodialysis (HD). Many causes can contribute to this higher prevalence, from vascular calcification to cerebral hypoperfusion, oxidative damage and uremic toxins. Both frailty and CI can lead to an increase morbimortality. Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) are two screening instruments with a good application profile for cognitive evaluation, as well as the Frailty Clinical Scale (FCS). However, there are few studies using these scales on HD patients and demonstrating association between frailty, cognitive impairment and their clinical characteristics. The aim of this study is to investigate the prevalence of coexisting cognitive impairment and frailty in our center hemodialysis patients and its association with clinical characteristics and outcomes. Method: Thirty-two patients undergoing hospital hemodialysis program were assessed. The MoCA scale, MMSE and FCS were applied. Data were analyzed using appropriate statistical methods, using SPSS ® version 22.0. The significance level considered was 5%. Results: Thirty-two patients aged between 30 and 90 years were evaluated, with a mean of 61.63 years (SD ± 18.26), without gender predominance. The prevalence of deficits was 78.1% and 37,5% in MoCA and MMSE, respectively, without differences between gender. The prevalence of frailty (≥3) was 43.8%. Patients with deficit assessed by MoCA and MMSE were on average 15 years and 20 years older, respectively, than patients without deficit (p = 0.002). We found a statistically significant association between deficit measured by MMSE and frailty (p &lt;.001), with higher prevalence of frailty (83.3%) in individuals with deficit compared to individuals without deficit, where the prevalence of frailty was 20.0%. The deficit assessed by MMSE was also associated with time on dialysis (p = .029). No statistically significant associations were detected between MoCA and frailty over time on dialysis or between deficit measured by MoCA and frailty. Regarding patients’ comorbidities, there were no statistically significant differences between deficit assessed by MoCA and MMSE and presence of diabetes mellitus, hypertension and dyslipidemia. Deficits assessed by MoCA, MMSE, and Frailty were not associated with phosphoremia and also there was no association between presence of significative hypotension episodes during HD and these scales. Dialysis efficacy (kt/v) was not statistically associated with MoCA and MMSE deficits. Similarly, no association was found between Kt / v and frailty. Conclusion: In our study, prevalence of CI and frailty in hemodialysis patients was high. Time on dialysis program was related in a statistically significant way with CI and there was higher prevalence of frailty in individuals with deficit measured by MMSE. However, we did not find a correlation between dialysis efficacy, comorbidities and vascular risk factors and cognitive deficit or frailty score. The epidemiology and natural history of cognitive impairment and its association with frailty are important to understand among patients on HD for early intervention and management.
