Sleep disorders and chronic kidney disease.

Abstract: Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.

Motivations and barriers to exercise in chronic kidney disease: a qualitative study

Abstract: Background Exercise has the potential to modulate a number of complications associated with chronic kidney disease (CKD). However, typically, CKD patients lead very sedentary lifestyles, the reasons for which are not fully known. The aim of this qualitative study was to gain an understanding of the motivators, barriers and beliefs held by CKD patients regarding exercise. Methods We conducted 3 focus groups and 22 semi-structured interviews. Data were collected from nephrology outpatient clinics in the United Kingdom. A total of 36 individuals with CKD stages 1-5 not requiring renal replacement therapy, aged 26-83 years participated in this study. This manuscript outlines the findings from patients with CKD stages 3-5. Focus groups and interviews were transcribed verbatim and analysed thematically. Results Positive attitudes to exercise reflected autonomous motivations including: exercising for health; enjoyment and social interaction. Family support and goal setting were seen as motivators for exercise and the accessibility of local facilities influenced activity levels. Barriers to exercise were poor health, fear of injury or aggravating their condition, a lack of guidance from healthcare professionals and a lack of facilities. Conclusions These findings are an important first stage in the development of a CKD-specific exercise behaviour change intervention. Interventions should operate at multiple levels, with a focus on improving patient autonomy and exercise self-efficacy, support networks and the physical environment (e.g. the accessibility of local facilities). In addition, strategies are required to ensure that the healthcare system is actively promoting and routinely supporting exercise for all patients with CKD.

Cognitive Impairment in Chronic Kidney Disease: Vascular Milieu and the Potential Therapeutic Role of Exercise

Abstract: Chronic kidney disease (CKD) is considered a model of accelerated aging. More specifically, CKD leads to reduced physical functioning and increased frailty, increased vascular dysfunction, vascular calcification and arterial stiffness, high levels of systemic inflammation, and oxidative stress, as well as increased cognitive impairment. Increasing evidence suggests that the cognitive impairment associated with CKD may be related to cerebral small vessel disease and overall impairment in white matter integrity. The triad of poor physical function, vascular dysfunction, and cognitive impairment places patients living with CKD at an increased risk for loss of independence, poor health-related quality of life, morbidity, and mortality. The purpose of this review is to discuss the available evidence of cerebrovascular-renal axis and its interconnection with early and accelerated cognitive impairment in patients with CKD and the plausible role of exercise as a therapeutic modality. Understanding the cerebrovascular-renal axis pathophysiological link and its interconnection with physical function is important for clinicians in order to minimize the risk of loss of independence and improve quality of life in patients with CKD.
