    Abstract Background: NICE Guideline NG107, "Renal replacement therapy and conservative management" (Renal replacement therapy and conservative management (NG107); 2018:1-33) was published in October 2018 and replaced the existing NICE guideline CG125, "Chronic Kidney Disease (Stage 5): peritoneal dialysis" (Chronic kidney disease (stage 5): peritoneal dialysis | Guidance | NICE; 2011) and NICE Technology Appraisal TA48, "Guidance on home compared with hospital haemodialysis for patients with end-stage renal failure"(Guidance on home compared with hospital haemodialysis for patients with end-stage renal failure (Technology appraisal guideline TA48); 2002) The aim of the NICE guideline (NG107) was to provide guidance on renal replacement therapy (RRT), including dialysis, transplant and conservative care, for adults and children with CKD Stages 4 and 5. The guideline is extremely welcomed by the Renal Association and it offers huge value to patients, clinicians, commissioners and key stakeholders. It overlaps and enhances current guidance published by the Renal Association including "Haemodialysis" (Clinical practice guideline: Haemodialysis; 2019) which was updated in 2019 after the publication of the NICE guideline, "Peritoneal Dialysis in Adults and Children" (Clinical practice guideline: peritoneal Dialysis in adults and children; 2017) and "Planning, Initiation & withdrawal of Renal Replacement Therapy" (Clinical practice guideline: planning, initiation and withdrawal of renal replacement therapy; 2014) (at present there are no plans to update this guideline). There are several strengths to NICE guideline NG107 and we agree with and support the vast majority of recommendation statements in the guideline. This summary from the Renal Association discusses some of the key highlights, controversies, gaps in knowledge and challenges in implementation. Where there is disagreement with a NICE guideline statement, we have highlighted this and a new suggested statement has been written.

    Abstract The impact of dialysis on cognitive trends is uncertain. Kurella Tamura et al. evaluated cognitive trajectories in 212 participants from the Chronic Renal Insufficiency Cohort study and found that dialysis initiation was associated with a decline in executive function. This is consistent with a cerebrovascular basis for cognitive impairment in patients with renal disease. However, larger corroborative studies are needed while targets for intervention are identified to ameliorate dialytic effects on cognitive function.

    Abstract Background: Glucose-containing dialysate underpins peritoneal dialysis (PD) therapy. However, its use is associated with amino acid loss in the dialysis effluent, a risk factor for protein-energy wasting (PEW) in PD patients. Amino acid-based dialysis solutions (AAD) may ameliorate this loss. However, the evidence of clinical benefit in preventing PEW is unclear. The aim of this review was to assess the effect of AAD versus standard dialysis solutions (STD) on anthropometric measures and serum albumin.
    Methods: Studies up until 30 September 2020 were identified from databases including MEDLINE and Embase, using a prespecified protocol (PROSPERO - CRD42020209581). Studies evaluating adults on PD were included. Data pertaining to muscle mass (primary outcome), other anthropometric measures and serum albumin were extracted. A meta-analysis of the eligible studies was conducted.
    Results: A total of 6945 abstracts were reviewed, from which 14 studies (9 randomised and 5 non-randomised) were included. There was no significant difference in any of the anthropometric measures, between AAD and STD during follow-up. Serum albumin at 6 months was statistically lower with AAD compared to STD [mean difference = -0.89 (95%CI -1.77 to -0.01,
    Conclusions: AAD may not alter anthropometric measures when compared to STD. The impact on serum albumin is uncertain, with an estimated difference that is unlikely to be of clinical value. These findings should be cautiously interpreted due to low quality of the evidence. Robust studies are needed to address the limitations in evidence.

    Abstract The incidence of older patients with end stage renal disease is on the increase. This group of patients have multiple comorbidities and a high symptom burden. Dialysis can be life sustaining for such patients. But it is often at the expense of quality of life, which starts to decline early in the pathway of chronic kidney disease. Quality of life is also important to patients and is a major determinant in decisions regarding renal replacement. As a result, validated patient-reported outcome measures are increasingly used to assess quality of life in renal patients. Cognitive impairment, depression, malnutrition and function decline are non-renal determinants of quality of life and mortality. They are under-recognised in the renal population but are potentially treatable, if not preventable. This review article discusses aetio-pathogenesis, prevalence and impact of these four outcomes, advocating regular screening for early identification and management.

    Abstract Management of older people on dialysis requires focus on the wider aspects of aging as well as dialysis. Almost all frail and older patients receiving dialysis will default to in-center hemodialysis, although the availability of assisted peritoneal dialysis enables dialysis at home. As with any disease management decision, patients approaching end-stage renal disease need all the appropriate facts about their prognosis, the natural history of their disease without dialysis, and the resulting outcomes and complications of the different dialysis modalities. Hemodialysis in the older age group can be complicated by intradialytic hypotension, prolonged time to recovery, and vascular access-related problems. Peritoneal dialysis can be difficult for older patients with impaired physical or cognitive function and can become a considerable burden. Use of incremental dialysis, changes in hemodialysis frequency, and delivery and use of assistance for peritoneal dialysis can ameliorate quality of life for older patients. Understanding each individual's goals of care in the context of his or her life experience is particularly important in the elderly, when overall life expectancy is relatively short, and life experience or quality of life may be the priority. Indeed, some patients select the option of no dialysis or conservative care. With multifaceted assessments of care, physicians should be able to give individual patients the ability to select and continue to make the best decisions for their care.

    Abstract Introduction: Peritoneal dialysis (PD)-related peritonitis (PDRP) is a common cause of transfer to hemodialysis, patient morbidity, and is a risk factor for mortality. Associated patient anxiety can deter selection of PD for renal replacement therapy. Diagnosis relies on hospital laboratory tests; however, this might be achieved earlier if such information was available at the point-of-care (POC), thereby significantly improving outcomes. The presence of culturable microbes and the concentration of leukocytes in effluent both aid peritonitis diagnosis, as specified in the International Society for Peritoneal Dialysis (ISPD) diagnostic guidelines. Here, we report the development of 2 new methods providing such information in simple POC tests.
    Methods: One approach uses a tetrazolium-based chemical reporting system, primarily focused on detecting bacterial contamination and associated vancomycin-sensitivity. The second approach uses a novel forward light-scatter device (QuickCheck) to provide an instant quantitative cell count directly from PD patient effluent.
    Results: The tetrazolium approach detected and correctly distinguished laboratory isolates, taking 10 hours to provide non-quantitative results. We compared the technical performance of the light scatter leukocyte counting approach with spectrophotometry, hemocytometer counting and flow cytometry (Sysmex) using patient effluent samples. QuickCheck had high accuracy (94%) and was the most precise (coefficient of variation <4%), showing minimal bias, overall performing similarly to flow cytometry.
    Conclusion: These complementary new approaches provide a simple means to obtain information to assist diagnosis at the POC. The first provides antibiotic sensitivity following 10 hours incubation, whereas the second optical approach (QuickCheck), provides instant accurate total leukocyte count.
