Elderly dialysis, kidney disease, dementia

BACKGROUND: Information of short-term prognosis after hemodialysis (HD) introduction is important for elderly patients with chronic kidney disease (CKD) and their families choosing a modality of renal replacement therapy. Therefore, we developed a risk score to predict early mortality in incident elderly Japanese hemodialysis patients. MATERIALS AND METHODS: We analyzed data of incident elderly HD patients from a nationwide cohort study of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) to develop a prognostic risk score...

BACKGROUND: Gait abnormality is a serious problem among hemodialysis patients. Whole-body vibration is a simple exercise that induces sustained muscular contractions through mechanical vibrations. This training improved gait ability in older adults. We aimed to investigate the effect of whole-body vibration on balance and gait ability in older hemodialysis patients. METHODS: We conducted a 12-week, open-label, multicenter, randomized controlled trial of 98 hemodialysis patients, who were aged ≥65 years, from three dialysis centers in Japan...

BACKGROUND: Elevated parathyroid hormone (PTH) levels have been reported as a potential risk factor for cognitive impairment. Compared to the general population, older adults with end-stage renal disease (ESRD) who are frequently affected by secondary hyperparathyroidism (SHPT) are at increased risk of developing dementia. The main objective of our study was to evaluate if the risk of dementia in older (age ≥ 65) ESRD patients differed if they were treated for SHPT. METHODS: Using the United States Renal Data System (USRDS) and Medicare claims, we identified 189 433 older adults without a diagnosis of dementia, who initiated dialysis between 2006-2016...

OBJECTIVES: Among kidney disease patients ≥80 years progressing to end-stage renal disease, there is growing interest in conservative nondialytic management approaches. However, among those who have initiated hemodialysis, little is known about the impact of withdrawal from dialysis on mortality, nor the patient characteristics associated with withdrawal from dialysis. STUDY DESIGN: Historical cohort study. SETTING AND PARTICIPANTS: We examined 133,162 incident hemodialysis patients receiving care within a large national dialysis organization from 2007 to 2011...

BACKGROUND: Renal Supportive/Palliative Care is gaining gradual recognition as a patient-centered care approach that should be integrated to the traditional disease-centered model of care, mainly in elder patients with advanced chronic kidney disease (CKD). The objective of this study was to assess knowledge, perceptions, attitude, experience and interest in palliative care among renal care providers. METHODS: Online survey, administered between May 23 to June 13, 2017 to members of the Brazilian Society of Nephrology (BSN)...

Chronic kidney disease (CKD) is common, its prevalence increasing with age. Cognitive impairment is common in the elderly, in CKD and in those on maintenance haemodialysis. As cognitive impairment is the precursor to dementia, the identification of reversible risk factors for cognitive decline is the key to reducing dementia risk. Arterial stiffness is one such potential risk factor. It is independently associated with cardiovascular outcome in dialysis patients. Importantly, the recent demonstration of an independent association between arterial stiffness and cognitive impairment in these patients suggests that vascular stiffness might be potentially causative in the development of cognitive impairment and also be an opportune target for interventions...

The prevalence of cognitive disorders in CKD-patients is high. A screening of dementia is easy to perform. There are increasing possibilities of cognitive training in dialysis patients.

BACKGROUND: Although the proportion of the elderly patients with incident end-stage renal disease (ESRD) patients has been increasing in Korea, there has been a lack of information on outcomes of dialysis treatment. This study aimed to assess the survival rate and to elucidate predictors for all-cause mortality among elderly Korean patients initiating dialysis. METHODS: We analyzed 11,301 patients (6,138 men) aged 65 years or older who had initiated dialysis from 2005 to 2008 and had followed up (median, 37...

The burden of cognitive impairment appears to increase with progressive renal disease, such that the prevalence of dementia among those starting dialysis, or those already established on dialysis, is high. The appropriateness of dialysis initiation in this population has been questioned, and current Renal Physician Association guidelines suggest forgoing dialysis in individuals who have dementia and lack awareness of self and environment. Patients are, however, also entitled to equal rights and respect, equal access to health care services, and an opportunity to engage in shared decision-making processes, particularly if there is concern over reversibility of disease...

BACKGROUND: Reasons underlying dialysis decision-making in Octogenarians and Nonagenarians have not been further explored in prospective studies. METHODS: This regional, multicentre, non-interventional and prospective study was aimed to describe characteristics and quality of life (QoL) of elderly (≥80 years of age) with advanced chronic kidney disease (stage 3b-5 CKD) newly referred to nephrologists. Predictive factors of death and dialysis initiation were also assessed using competing-risk analyses...

BACKGROUND: Renal failure occurs more frequently among the elderly and elderly patients comprise an increasing proportion of dialysis patients. The objective of this paper is to review the frequency of cognitive impairment among elderly people in dialysis, and discuss causes and consequences of cognitive impairment and dementia in patients with end-stage renal disease. Prevention and treatment of cognitive impairment are discussed. MATERIAL AND METHODS: The review is based on literature retrieved from a search of Medline and other web-sites, review papers and clinical experience...

Predialysis is a clinical situation in which the patient has significant impairment of kidney function that will ultimately lead to either death or inclusion in kidney replacement therapy (dialysis and/or transplantation). Since a practical and effective dialysis technique was introduced, the length and quality of survival of patients with end-stage renal failure has constantly increased. Contraindications for dialysis are almost never of a renal origin. The obstacles are the concomitant diseases of the patient...

In the last two decades, most developed countries have seen a continuous growth in the number of elderly patients with end-stage renal disease commencing renal replacement therapy. Despite the many advantages that peritoneal dialysis (PD) offers to elderly patients with ESRD, it is still underutilized in older patients. Older patients are much more vulnerable to the problems associated with aging, which may affect their level of independence and their long-term prognosis. Those patients have physiological changes related to aging and common health problems such as anxiety, depression, dementia, visual impairment, and cognitive impairment, all of which interfere with self-performing PD...

BACKGROUND: The incidence of chronic renal failure increase with the age. The selection of patient to dialysis has been increasing in spite of the high comorbidity. Moreover, in our clinical practice the aged patient is not contraindicated to dialysis. However, in the nephrology clinical practice not all the patients start the treatment with dialysis. OBJECTIVE The aim of our study has been to compare the characteristics of the patients who had not been dialyzed between the periods 1992-1995 and 2000-2003 to analyze the trend of the nephrology clinical practice...

BACKGROUND: Recent studies suggest a high prevalence of cognitive impairment and dementia in persons with end-stage renal disease (ESRD), yet risk factors for dementia and its prognostic significance in persons with ESRD remain unclear. The goals of this study were to determine the prevalence, correlates and dialysis-related outcomes of dementia in an international sample of haemodialysis patients. METHODS: We analysed data collected from a cohort of 16 694 patients in the Dialysis Outcomes and Practice Patterns Study...

The provision of patient-focused care to the elderly is often fraught with many ethical and challenging dilemmas. However, for health care professionals, these dilemmas can be magnified when the chronic disease is accompanied by dementia. Such was the case of Mrs. A. The multidisciplinary team of a 36-bed acute care unit identified the challenges they experienced while caring for a 65-year-old female with multiple medical problems: diabetes; hypertension; cardiovascular disease; end stage renal disease and dementia probably due to cardiovascular and metabolic causes...

Cessation of life-support treatment is an appropriate option for situations in which the burdens of therapy substantially outweigh the benefits. Decisions to withdraw dialysis now precede 1 in 4 deaths of patients who have end-stage renal disease. Guidelines have been recently published to assist clinicians in making these complex and emotionally charged determinations, and they include: relying on shared decision making by all participants, obtaining informed consent, estimating the prognosis on dialysis, adopting a systematic approach for conflict resolution of disagreements, honoring advance directives, and ensuring the provision of palliative care...

Serum aluminium was significantly raised (p < 0.01) up to 2-3-fold, in patients with dementia including Alzheimers Disease (AD) 0.66 +/- 0.2 (mumol/l mean +/- 1 s.d.) and patients on regular aluminium hydroxide therapy 0.54 +/- 0.17, compared with healthy volunteers 0.21 +/- 0.13, although not as high as in patients with end stage renal failure on regular dialysis 0.88 +/- 0.42. The urine outputs (mumol/l mean +/- 1 s.d.) of aluminium and silicon, respectively, were also significantly increased up to 5-fold in dementia 2...

Aging will be a serious social problem in the future. The number of patients of 75 years and over with end-stage renal disease (ESRD) is bound to increase. The time has come to pay greater attention to their problems before and during dialysis treatment. Prevention of ESRD is an important challenge, especially in the field of vascular diseases which are the main cause of ESRD in the elderly. The exact number of elderly patients who will require dialysis in the next few years is difficult to foresee. It is only when the incidence of patients starting dialysis at 75 and over levels off that we may assume that elderly patients are no longer rejected from treatment; we could then assess the actual need in dialysis facilities...
