Delivering Person-Centered Peritoneal Dialysis.

Peritoneal dialysis (PD) enables people to have a home-based therapy, permitting greater autonomy for individuals along with enhanced treatment satisfaction compared with in-center dialysis care. The burden of treatment on PD, however, remains considerable and underpins the need for person-centered care. This reflects the need to address the patient as a person with needs and preferences beyond just the medical perspective.

Home dialysis therapies.

Home dialysis therapies offer a significant benefit to patients in respect of quality of life and autonomy, as compared with in-centre haemodialysis. There is significant unwarranted variation across the world in the availability of both peritoneal dialysis (PD) and home haemodialysis, which has led in the UK to a recommendation of a minimum 20% prevalent rate of dialysis patients at home. Key advances in PD have included changes in the approach to prescribing PD and the use of assisted dialysis.

Outcome and effect of vaccination in SARS-CoV-2 Omicron infection in hemodialysis patients: a cohort study.

Background: Hemodialysis patients are at high risk of Covid-19, though vaccination has significant efficacy in preventing and reducing the severity of infection. Little information is available on disease severity and vaccine efficacy since the dissemination of the Omicron variant.

Methods: In a multi-center study, during a period of the epidemic driven by the Omicron variant, all hemodialysis patients positive for SARS-CoV-2 were identified.

Severity of COVID-19 after Vaccination among Hemodialysis Patients: An Observational Cohort Study.

Background And Objectives: Patients receiving hemodialysis are at high risk from coronavirus disease 2019 (COVID-19) and demonstrate impaired immune responses to vaccines. There have been several descriptions of their immunologic responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, but few studies have described the clinical efficacy of vaccination in patients on hemodialysis.

Design, Setting, Participants, & Measurements: In a multicenter observational study of the London hemodialysis population undergoing surveillance PCR testing during the period of vaccine rollout with BNT162b2 and AZD1222, all of those positive for SARS-CoV-2 were identified.

Assisted peritoneal dialysis across Europe: Practice variation and factors associated with availability.

Background: In Europe, the number of elderly end-stage kidney disease patients is increasing. Few of those patients receive peritoneal dialysis (PD), as many cannot perform PD autonomously. Assisted PD programmes are available in most European countries, but the percentage of patients receiving assisted PD varies considerably.

Barriers and opportunities to increase PD incidence and prevalence: Lessons from a European Survey.

Introduction: Peritoneal dialysis (PD) remains underutilised and unplanned start of dialysis further diminishes the likelihood of patients starting on PD, although outcomes are equal to haemodialysis (HD).

Methods: A survey was sent to members of EuroPD and regional societies presenting a case vignette of a 48-year-old woman not previously known to the nephrology department and who arrives at the emergency department with established end-stage kidney disease (unplanned start), asking which dialysis modality would most likely be chosen at their respective centre. We assessed associations between the modality choices for this case vignette and centre characteristics and PD-related practices.

The Effect of Kidney Biopsy on Glomerular Filtration Rate: A Frequent Patient Concern.

The effect of percutaneous kidney biopsy on glomerular filtration rate has never been identified, though it is frequently a concern raised by patients. Following a clinical interaction with an inquisitive patient undergoing her fifth biopsy, we attempted to estimate the effect using retrospective data. In a cohort of patients with stable kidney function undergoing transplant biopsy without clinical indication (as part of a surveillance programme) the effect of biopsy was observed as a step change in glomerular filtration rate.

Recent advances in treatment of haemodialysis.

Haemodialysis remains the most widely used treatment for patients with end-stage renal disease. Despite the progress that has occurred in the treatment of end-stage renal disease over the last six decades, there has been a failure to translate this into the desired clinical benefits, with morbidity and mortality rates among patients on haemodialysis remaining unacceptably high. Recently, however, there have been expectations that the significant advances that took place over the last few years may result in improved outcomes.

Epidemiology of COVID-19 in an Urban Dialysis Center.

Background: During the coronavirus disease 2019 (COVID-19) epidemic, many countries have instituted population-wide measures for social distancing. The requirement of patients on dialysis for regular treatment in settings typically not conducive to social distancing may increase their vulnerability to COVID-19.

Methods: Over a 6-week period, we recorded new COVID-19 infections and outcomes for all adult patients receiving dialysis in a large dialysis center.

International Society for Peritoneal Dialysis Practice Recommendations: The view of the person who is doing or who has done peritoneal dialysis.

The 2019 International Society for Peritoneal Dialysis (ISPD) Practice Recommendations were prepared by a committee invited by the ISPD to develop new practice recommendations for prescribing high-quality, goal-directed peritoneal dialysis (PD). Further input was sought at the stage of the first draft of the proposed recommendations by circulating drafts of the recommendations and articles to an international selection of people who were either actively doing PD or who were previously treated with PD, as well as caregivers, to ask for their feedback. A diverse group of 22 people from 8 countries across 5 continents provided their feedback covering the main recommendations as well as the accompanying articles.

Flexibility in peritoneal dialysis prescription: Impact on technique survival.

Background: Patient burnout is a major cause of technique failure on peritoneal dialysis (PD). Reducing the PD prescription on an individual basis, dependent upon residual kidney function (RKF), may have a role in prolonging time on PD by reducing dialysis burden. This retrospective study aimed to determine the safety and impact of flexible PD prescribing on technique and patient survival.

Repeat Peritoneal Dialysis Exit-Site Infection: Definition and Outcomes.

The most common complication of peritoneal dialysis (PD) is infection. Despite this, there are no clear guidelines for the management of repeat exit-site infection (ESI), and best practice is not known. We describe our unit's experience of repeat ESI and clinical outcomes in this cohort.

Variation in renal responses to exercise in the heat with progressive acclimatisation.

Objectives: To investigate changes in renal status from exercise in the heat with acclimatisation and to evaluate surrogates markers of Acute Kidney Injury.

Design: Prospective observational cohort study.

Methods: 20 male volunteers performed 60 min standardised exercise in the heat, at baseline and on four subsequent occasions during a 23-day acclimatisation regimen.

Conventional dialysis in the elderly: How lenient should our guidelines be?

There has been a dramatic, worldwide expansion in life expectancy across the last century. This has resulted in a progressively more elderly and comorbid population. It is increasingly recognized that healthcare in this group needs to move to the concept of "adding life to years".

Heterogeneity in the nonplanarity and arterial curvature of arteriovenous fistulas in vivo.

Objective: Native arteriovenous fistulas (AVFs) for hemodialysis are susceptible to nonmaturation. Adverse features of local blood flow have been implicated in the formation of perianastomotic neointimal hyperplasia that may underpin nonmaturation. Whereas computational fluid dynamic simulations of idealized models highlight the importance of geometry on fluid and vessel wall interactions, little is known in vivo about AVF geometry and its role in adverse clinical outcomes.

Nivolumab-induced fulminant diabetic ketoacidosis followed by thyroiditis.

Unlabelled: Five days following the 3rd cycle of nivolumab, a monoclonal antibody, which acts as immune checkpoint inhibitor against the programmed cell death protein-1, for metastatic lung adenocarcinoma, a 56-year-old woman presented at the hospital critically ill. On admission, she had severe diabetic ketoacidosis (DKA), as evidenced by venous glucose of 47 mmol/L, blood ketones of 7.5 mmol/L, pH of 6.

The melanoma-specific graded prognostic assessment does not adequately discriminate prognosis in a modern population with brain metastases from malignant melanoma.

Background: The melanoma-specific graded prognostic assessment (msGPA) assigns patients with brain metastases from malignant melanoma to 1 of 4 prognostic groups. It was largely derived using clinical data from patients treated in the era that preceded the development of newer therapies such as BRAF, MEK and immune checkpoint inhibitors. Therefore, its current relevance to patients diagnosed with brain metastases from malignant melanoma is unclear.

Problems associated with hemodialysis and travel.

Background: While there is a recognized risk of hepatitis C acquisition associated with dialysis away from the "home" center, there is little documented data on the effect that dialysis while traveling has on the dialysis patient's health. This study was designed to examine the incidence of travel within a hemodialysis population and to ascertain whether travel was associated with morbidity for patients on hemodialysis.

Methods: Travel data were collected prospectively over a 6-month period, from April 2009, for all patients receiving maintenance hemodialysis across our dialysis centers.

Complication of diagnostic pleural aspiration: is it of value in hemodialysis patients?

Pleural effusions are common in hemodialysis patients and are associated with significant morbidity. Diagnostic pleural aspiration and subsequent biochemical analysis can be used to differentiate exudates and transudates. In particular, Light's criteria have been validated in the general population although their efficacy in hemodialysis patients is unclear.
