Our findings demonstrate the importance of patient-tailored counselling on serum P management.

Objective Intradialytic exercise (IDE) is not yet a routine practice for hemodialysis patients, the lack of guidelines supporting it being a major reason. This systematic review and meta-analysis of aerobic IDE interventions examined the efficacy of IDE regarding quality of life (QOL), serum phosphorus, dialysis efficiency, inflammatory status, vitamin D3, parathyroid hormone, intake of phosphate binders, mortality and hospitalization rate. Methods Pubmed, Medline (Ovid), Embase (Ovid), Cochrane, and Cinahl (EBSCO) databases were searched to retrieve studies up to June 12, 2018. A manual reference search was also performed. Studies were included if they evaluated (a) aerobic IDE effect on at least one of our study parameters, (b) adult hemodialysis patients, (c) patients for > 1 month. Results Twenty-two studies were retrieved (706 participants), of which 12 were eligible for meta-analysis. Aerobic IDE had a significant positive effect on the QOL physical component score (QOL-PSC) and on mental component score (QOL-MCS) of SF36, but not on serum phosphorus or Kt/V. Conclusions IDE incorporation into clinical practice has a significant positive effect on QOL-PSC and QOL-MCS. In the reviewed studies, IDE did not result in any health hazard in hemodialysis patients. Nevertheless, future research should assess the long-term effectiveness and safety of IDE. The limitations of this review include the lack of quality analysis of the studies, the limited number of studies that could be included in the meta-analysis, the diversity in the exercise intensity, duration and modality, and the limited data for several outcomes.

Strategies to enhance knowledge of and adherence to dietary guidelines for management of hyperphosphatemia in hemodialysis patients have been studied extensively over the past decade. This review is the first to compile all of them (2003-2013) and conduct a meta-analysis through calculation of effect size, with the aim of identifying the optimal nutrition education methods for effective management of hyperphosphatemia in hemodialysis patients. The following strategies were identified as being effective in changing dietary behavior: 1) use of self-evaluation and self-regulation techniques within educational tools, along with easy-to-apply skills; 2) individualized counseling by a renal dietitian provided just before the hemodialysis session; 3) high-intensity education; and 4) long duration of interventions. Future studies should focus on conducting randomized controlled trials with powered samples to help generate stronger evidence.
