Abstract
BACKGROUND Mineral bone disorder (MBD) in chronic kidney disease (CKD) is associated with high symptom burden, fractures, vascular calcification, cardiovascular disease and increased morbidity and mortality. CKD-MBD studies have been limited in peritoneal dialysis (PD) patients. Here, we describe calcium and parathyroid hormone (PTH) control, related treatments and mortality associations in PD patients. METHODS We used data from eight countries (Australia and New Zealand (A/NZ), Canada, Japan, Thailand, South Korea, United Kingdom, United States (US)) participating in the prospective cohort Peritoneal Dialysis Outcomes and Practice Patterns Study (2014-2022) among patients receiving PD for >3 months. We analysed the association of baseline PTH and albumin-adjusted calcium (calciumAlb) with all-cause mortality using Cox regression, adjusted for potential confounders, including serum phosphorus and alkaline phosphatase. RESULTS Mean age ranged from 54.6 years in South Korea to 63.5 years in Japan. PTH and serum calciumAlb were measured at baseline in 12,642 and 14,244 patients, respectively. Median PTH ranged from 161 (Japan) to 363 pg/mL (US); mean calciumAlb ranged from 9.1 (South Korea, US) to 9.8 mg/dL (A/NZ). The PTH/mortality relationship was U-shaped, with the lowest risk at PTH 300-599 pg/mL. Mortality was nearly 20% higher at serum calciumAlb 9.6+ mg/dL versus 8.4-<9.6 mg/dL. MBD therapy prescriptions varied substantially across countries. CONCLUSIONS A large proportion of PD patients in this multi-national study have calcium and/or PTH levels in ranges associated with substantially higher mortality. These observations point to the need to substantially improve MBD management in PD to optimise patient outcomes. LAY SUMMARY Chronic kidney disease-mineral bone disorder (MBD) is a systemic condition, common in dialysis patients, that results in abnormalities in parathyroid hormone (PTH), calcium, phosphorus and vitamin D metabolism. A large proportion of peritoneal dialysis (PD) patients in this current multi-national study had calcium and/or PTH levels in ranges associated with substantially higher risks of death. Our observational study design limits our ability to determine whether these abnormal calcium and PTH levels cause more death due to possible confounding that was not accounted for in our analysis. However, our findings, along with other recent work showing 48-75% higher risk of death for the one-third of PD patients having high phosphorus levels (>5.5 mg/dL), should raise strong concerns for a greater focus on improving MBD management in PD patients.

Abstract
Background Peritoneal dialysis (PD)-related peritonitis is a major complication of PD. Wide variations in peritonitis prevention, treatment strategies and consequences are seen between countries. These between-country differences may result from modifiable risk factors and clinical practices. Methods A total of 1225 Japanese PD patients were included and prospectively followed in the Peritoneal Dialysis Outcomes and Practice Patterns Study phase 1 (2014-2018) and phase 2 (2018-2022). Associations between PD-related peritonitis and various risk factors were assessed by Cox proportional hazards survival models. Results During follow-up (median 1.52 years), 539 peritonitis episodes were experienced by 364 patients. The country crude peritonitis rate was 0.27 episodes/patient-year. In the fully adjusted model, noticeable patient-level factors associated with experiencing any peritonitis included age {hazard ratio [HR] 1.07 per 5-year increase [95% confidence interval (CI) 1.01-1.14]}, serum albumin level [HR 0.63 per 1 g/dl higher (95% CI 0.48-0.82)] and continuous ambulatory peritoneal dialysis (PD) [HR 1.31 versus automated PD (95% CI 1.05-1.63)]. The adoption of antibiotic prophylaxis practice at the time of PD catheter insertion [HR 0.63 (95% CI 0.51-0.78)] or when having complicated dental procedures [HR 0.74 (95% CI 0.57-0.95)] or lower endoscopy [HR 0.69 (95% CI 0.54-0.89)] were associated with lower hazards of any peritonitis, while a routine facility practice of having more frequent regular medical visits was associated with a higher hazard. Conclusion Identification of risk factors in Japan may be useful for developing future versions of guidelines and improving clinical practices in Japan. Investigation of country-level risk factors for PD-related peritonitis is useful for developing and implementing local peritonitis prevention and treatment strategies.

Abstract
Key Points This is the largest analysis of incident automated peritoneal dialysis (PD) prescriptions conducted in the United States to date. There was limited variability of automated PD prescriptions across the first 4 months of therapy. PD prescriptions tailored to meet the dialysis needs and lifestyle of patients may make PD a more attractive choice and increase longevity on PD. Background Changes in health care policies and recognition of patient benefit have contributed to increases in home-based dialysis, including peritoneal dialysis (PD). Frequent monitoring and early individualization of PD prescriptions are key prerequisites for the delivery of high-quality PD. The present analysis aimed to assess variations in PD prescriptions among incident automated PD (APD) patients who remain on PD for 120+ days. Methods This retrospective analysis examined data from patients within a large dialysis organization that initiated PD with APD between 2015 and 2019. PD prescription data were described by calendar year, timing of PD, and residual renal function categories. Changes in prescriptions from PD initiation (day 1) to day 120 were assessed descriptively. Results The cohort included 11,659 patients. The mean age at PD initiation increased from 2015 (56 [15] years) through 2019 (58 [15] years), whereas most other variables demonstrated no clear temporal change. Most patients (86%) had nighttime PD prescribed, with an average of 4.9 (1.3) cycles per day, a mean total treatment volume of 9.3 (2.5) L, and a median daily total dwell time of 7 (6–9.5) hours. Relative to day 1 nighttime prescriptions, there were (1 ) small increases in the proportion of patients receiving three or fewer cycles per day and those receiving 6+ cycles per day, (2 ) a 100 ml mean increase in fill volume per exchange, and (3 ) a mean 0.5 L increase in total nighttime treatment volume at day 120. When changes in nighttime APD prescriptions were examined at the patient level, 49% of patients had day 120 prescriptions that were unchanged from their initial prescription. Conclusions In the largest analysis of incident APD prescriptions conducted in the United States to date, most patients were prescribed nocturnal PD only with limited variability across the first 4 months of therapy.

Abstract
BACKGROUND Varying peritoneal dialysis (PD)-related clinical outcomes have been reported in different countries. As a participant of the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS), this study investigated the characteristics of Korean PD patients, PD facilities and the incidence rates of clinical outcomes including mortality and PD-related outcomes. METHODS From July 2019 to December 2021, a total of 766 Korean PD patients were included for analysis. Poisson regression analysis was used to explore the incidence rates of various clinical events including mortality, modality transfer, exit site or catheter tunnel infection and peritonitis. RESULTS Among the 766 patients (median age 55.5 years, males 59.5%), 276 were incident and 490 were prevalent PD patients. The incidence rates of events were as follows: all-cause mortality (0.048), modality transfer (0.051), exit site or catheter tunnel infection (0.054) and peritonitis (0.136) events per person year. The most common causative organism for exit site or tunnel infection was staphylococcus species (47%) and that for peritonitis was streptococcus (28%) followed by staphylococcus (27%) species. CONCLUSIONS Up to now, PDOPPS Korea has recruited 766 Korean PD patients and started documentation of major PD-related outcomes which occurred during the follow-up period. The overall incidence rates of clinical outcomes in Korean PD patients were relatively favourable. There was no statistically significant difference in the incidence rates of clinical outcomes according to both facility and patient factors.

Abstract
Traditionally, dialysis adequacy has been assessed primarily by determining the clearance of a single small solute, urea. Nevertheless, it has become increasingly evident that numerous other factors play a crucial role in the overall well-being, outcomes and quality of life of dialysis patients. Consequently, in recent years, there has been a notable paradigm shift in guidelines and recommendations regarding dialysis adequacy. This shift represents a departure from a narrow focus only on the removal of specific toxins, embracing a more holistic, person-centered approach. This new perspective underscores the critical importance of improving the well-being of individuals undergoing dialysis while simultaneously minimizing the overall treatment burden. It is based on a double focus on both clinical outcomes and a comprehensive patient experience. To achieve this, a person-centered approach must be embraced when devising care strategies for each individual. This requires a close collaboration between the healthcare team and the patient, facilitating an in-depth understanding of the patient's unique goals, priorities and preferences while striving for the highest quality of care during treatment. The aim of this publication is to address the existing evidence on this all-encompassing approach to treatment care for patients undergoing peritoneal dialysis and provide a concise overview to promote a deeper understanding of this person-centered approach.

Abstract
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. Shared decision making is central to the recent International Society for Peritoneal Dialysis recommendations for prescribing PD, balancing the potential benefits of PD on patient well-being with the burden associated with treatment. This review considers the role of high-quality goal-directed prescribing, incremental dialysis, and remote patient monitoring in reducing the burden of dialysis, including an approach to implementing incremental PD. Although patient-related outcomes are important in assessing the response to treatment and, particularly life participation, the corollary of dialysis burden, there are no clear routes to the clinical implementation of patient-related outcome measures. Delivering person-centered care is dependent on treating people both as individuals and as equal partners in their care.

Abstract
BACKGROUND Patients with end-stage kidney disease undergoing dialysis are at significant risk of stroke. Whether dialysis modality is associated with cerebrovascular disease is unclear. This study compared the risk of incident stroke in patients undergoing peritoneal dialysis or hemodialysis. METHODS Thirty-nine thousand five hundred forty-two patients without a history of stroke who initiated dialysis between January 1, 2010, and December 31, 2014 were retrospectively studied using Taiwan's National Health Insurance Research Database. We matched 3809 patients undergoing peritoneal dialysis (mean age 59±13 years; 46.5% women) and 11 427 patients undergoing hemodialysis (mean age 59±13 years; 47.3% women) by propensity score in a 1:3 ratio with follow-up through December 31, 2015. The primary outcome was incident acute ischemic stroke. Secondary outcomes included hemorrhagic stroke, acute coronary syndrome, and all-cause mortality. Cox proportional hazard models were conducted to determine hazard ratios of clinical outcomes according to the dialysis modality. RESULTS During a median follow-up of 2.59 (interquartile range 1.50-3.93) years, acute ischemic stroke, hemorrhagic stroke, and acute coronary syndrome occurred in 783 (5.1%), 376 (2.5%), and 1350 (8.9%) patients, respectively. In a multivariable Cox model that accounted for the competing risk of death, acute ischemic stroke occurred more frequently in the peritoneal dialysis group than in the hemodialysis group (subdistribution hazard ratio, 1.32 [95% CI, 1.13-1.54]; P=0.0005). There were no significant treatment-related differences in the risk of hemorrhagic stroke (subdistribution hazard ratio, 0.89 [95% CI, 0.70-1.14]; P=0.3571) and acute coronary syndrome (subdistribution hazard ratio, 0.99 [95% CI, 0.88-1.12]; P=0.9080). Patients undergoing peritoneal dialysis were more likely to die from any cause than patients undergoing hemodialysis (adjusted hazard ratio, 1.24 [95% CI, 1.15-1.33]; P<0.0001). CONCLUSIONS Peritoneal dialysis was associated with a significantly increased risk of acute ischemic stroke compared with hemodialysis. Further studies are needed to clarify whether more aggressive cerebrovascular preventive strategies might mitigate the excess risk for ischemic stroke among patients receiving peritoneal dialysis.

Abstract
Background An aging population living with chronic kidney disease and progressing to kidney failure, subsequently receiving peritoneal dialysis (PD) is growing. A significant proportion of these patients are also living with multi-morbidities and some degree of frailty. Recent practice recommendations from the International Society of Peritoneal Dialysis advocate for high-quality, goal-directed PD prescription, and the Standardized Outcomes of Nephrology-PD initiative emphasized the need for an individualized, goal-based care approach in all patients receiving PD treatment. In older patients, this approach to PD care is even more important. A frailty screening assessment, followed by a comprehensive geriatric assessment (CGA) prior to PD initiation and when dictated by change in relevant circumstances is paramount in tailoring PD care and prescription according to the needs, life goals, as well as clinical status of older patients with kidney failure. Summary Our review aimed to summarize the different dimensions to be taken into account when delivering PD care to the older patient - from frailty screening and CGA in older patients receiving PD to employing a personalized, goal-directed PD prescription strategy, to preserving residual kidney function, optimizing blood pressure (BP) control, and managing anemia, to addressing symptom burden, to managing nutritional intake and promoting physical exercise, and to explore telehealth opportunities for the older PD population. Key Messages What matters most to older PD patients may not be simply extending survival, but more importantly, to be living comfortably on PD treatment with minimal symptom burden in a home environment and to minimize treatment complications.

Abstract
Peritoneal dialysis (PD) offers lifestyle advantages over in-center hemodialysis (HD) and is less costly. However, in the United States, less than 12% of end-stage kidney disease (ESKD) patients are maintained on this modality. In this brief review, we discuss some of the factors underlying the low prevalence of PD. These include inadequate patient education, a shortage of sufficiently well-trained medical and nursing personnel, absence of infrastructure to support urgent start PD, and lack of support for assisted PD, among other factors. Understanding and addressing these various issues may help increase the prevalence of PD in the United States and globally.

Abstract
AIM To assess whether the peritoneal dialysis (PD) centres included in the Peritoneal Dialysis Outcomes and Practise Patterns Study (PDOPPS) in Thailand are representative of other PD centres in the country, based on 8 key performance indicators (KPIs 1-8). METHODS A retrospective analysis was conducted comparing PD-related clinical outcomes between PD centres included in the PDOPPS (the PDOPPS group) and those not included (the non-PDOPPS group) from January 2018 to December 2019. Logistic regression analysis was used to identify predictors associated with achieving the target KPIs. RESULTS Of 181 PD centres, 22 (12%) were included in the PDOPPS. PD centres in the PDOPPS group were larger and tended to serve more PD patients than those in the non-PDOPPS group. However, the process and outcome KPIs (KPIs 1-8) were comparable between the 2 groups. Large hospitals (≥120 beds), providing care to ≥100 PD cases and having experience for >10 years were independent predictors of achieving the peritonitis rate target of <0.5 episodes/year. Most PD centres in Thailand showed weaknesses in off-target haemoglobin levels and culture-negative peritonitis rate. CONCLUSIONS The PD centres included in Thai PDOPPS were found to be representative of other PD centres in Thailand in terms of clinical outcomes. Thus, Thai PDOPPS findings may apply to the broader PD population in Thailand.

Abstract
Introduction Low activity levels and poor physical function are associated with technique failure and mortality in people receiving peritoneal dialysis (PD). Adequate levels of physical function are required to maintain independence for people choosing this predominantly home-based therapy. The objective of this study was to identify the exercise-related perceptions and practices of PD clinicians globally. Methods We conducted a cross-sectional survey of PD clinicians from English-, Thai-, Spanish-, and Portuguese-speaking PD-prevalent countries exploring clinicians' perceptions and practices of swimming, activity following PD catheter insertion, lifting, and falls prevention. This study was convened by the International Society of Peritoneal Dialysis and Global Renal Exercise Network between July and December 2021. Results Of 100 of the highest PD-prevalent countries, 85 responded and were represented in the findings. A total of 1125 PD clinicians (448 nephrologists, 558 nephrology nurses, 59 dietitians, and 56 others) responded from 61% high-income, 32% upper middle-income and 7% lower middle-income countries. The majority (n = 1054, 94%) agreed that structured exercise programs would be beneficial for people receiving PD. Most respondents believed people on PD could perform more exercise (n = 907, 81%) and that abdominal strengthening exercises could be safely performed (n = 661, 59%). Compared to clinicians in high-income countries, clinicians from lower middle-income status (odds ratio [OR], 5.57; 1.64 to 18.9) are more likely to promote participation in physical activity. Conclusion Clinicians know the importance of physical activity in people receiving PD. Exercise counseling and structured exercise plans could be included in the standard care of people receiving PD to maintain independence.

A feasibility study of avoiding positive calcium balance and parathyroid hormone increase in patients on peritoneal dialysis. Bone Rep 2022; 17:101625. [PMID: 36217349 PMCID: PMC9547188 DOI: 10.1016/j.bonr.2022.101625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 09/05/2022] [Accepted: 09/28/2022] [Indexed: 11/28/2022] Open
Abstract
Background The effect of the dialysate calcium concentration (D[Ca]) on mineral and bone metabolism in patients on peritoneal dialysis (PD) is overlooked. D[Ca] of 1.75 mmol/L is still prescribed to many patients on PD around the world. Previous studies on the effects of reducing D[Ca] have been carried out before the incorporation of calcimimetics in clinical practice. We hypothesized that a reduction in D[Ca] is safe and without the risk of a rise in serum parathyroid hormone (PTH). Methods In this non-randomized clinical trial, the D[Ca] was reduced from 1.75 mmol/L to 1.25 mmol/L for one year in prevalent patients on PD. Demographic, clinical, and CKD-MBD-related biomarkers were evaluated at baseline, 3, 6, and 12 months of follow-up. Results 20 patients completed 1-year follow-up (56 ± 16 years, 50 % male, 25 % diabetic, 55 % with baseline parathyroid hormone – PTH >300 pg/mL). Over time, there was no significant change in calcium, phosphate, total alkaline phosphatase, 25(OH)-vitamin D or PTH, although adjustments in calcitriol and sevelamer prescription were required. After 1 year, absolute and percentual change in PTH levels were 36 (−58, 139) pg/mL, and 20 % (−28, 45) respectively. The proportion of patients with PTH > 300 pg/mL did not change during the follow-up (p = 0.173). Conclusion Knowing the risk of a positive calcium balance in patients on PD, reducing the D[Ca] concentration is a safe and valuable option, although medication adjustments are needed to detain PTH rising.

Abstract
BACKGROUND Although caregivers allow peritoneal dialysis (PD) patients with disabilities the opportunity to perform PD, it is crucial to clarify the safety and effectiveness of assisted PD performed by caregivers compared to self-PD. METHODS PD patients from 22 PD centres in Thailand were prospectively followed in the Peritoneal Dialysis Outcomes and Practice Patterns Study during 2016-2017. Patients receiving assisted PD performed by caregivers were matched 1:1 with self-PD patients using propensity scores calculated by logistic regression. The associations between assisted PD and risk of mortality, peritonitis and permanent transfer to haemodialysis (HD) were assessed by multivariable competing risk regression. RESULTS Of 778 eligible patients, 447 (57%) required assisted PD performed by caregivers. Most of the caregivers were family members (98%), while the rest were non-family paid caregivers (2%). Patient factors associated with assisted PD were older age, female gender, lower educational level, cardiovascular comorbidities, diabetes, automated PD modality, poorer functional status and lower blood chemistries (albumin, creatinine, sodium, potassium and phosphate). After 1:1 matching, the baseline characteristics were adequately matched, and 269 patients in each group were analysed. Compared with self-PD, assisted PD was significantly associated with an increased risk of all-cause mortality (adjusted sub-hazard ratio: 2.15, 95% confidence interval: 1.24-3.74). There were no differences in the occurrences of peritonitis and permanent HD transfer between the groups. CONCLUSIONS Assisted PD was required by more than half of Thai PD patients and was independently associated with a higher mortality risk. This may reflect causal effect or confounding by indication.

A randomized clinical trial to evaluate the effects of icodextrin on left ventricular mass index in peritoneal dialysis. Sci Rep 2022; 12:15776. [PMID: 36138087 PMCID: PMC9500040 DOI: 10.1038/s41598-022-20157-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 09/09/2022] [Indexed: 11/18/2022] Open
Abstract
Left ventricular hypertrophy is a risk factor for cardiovascular mortality in patients on peritoneal dialysis (PD). Because icodextrin has a greater ultrafiltration power compared with glucose-based solutions for long dwell, it could improve left ventricular mass by reducing fluid overload. This was a randomized clinical trial that included patients on PD recruited from 2 teaching hospitals, in Sao Paulo—Brazil. Patients were allocated to the control glucose group (GLU) or the intervention icodextrin (ICO) group. Clinical and cardiac magnetic resonance image (MRI) parameters were evaluated at baseline and 6 months after randomization. The primary outcome was the change in left ventricular mass adjusted by surface area (ΔLVMI), measured by cardiac MRI. A total of 22 patients completed the study (GLU, N = 12 and ICO, N = 10). Baseline characteristics such as age, sex, underlying disease, and time on dialysis were similar in both groups. At baseline, 17 patients (77.3%) presented with left ventricular hypertrophy with no difference between groups (p = 0.748). According to the total body water (TBW)/extracellular water (ECW) ratio, 36.8% and 80% of patients from GLU and ICO groups, respectively, were considered hypervolemic (p = 0.044). During follow-up, ΔLVMI was 3.9 g/m (− 10.7, 2.2) in GLU and 5.2 (− 26.8, 16.8) in ICO group (p = 0.651). ΔLVMI correlated with change in brain natriuretic peptide (r = 0.566, p = 0.044), which remained significant in a multiple regression analysis. The use of the icodextrin-based solution in prevalent patients on PD compared with a glucose-based solution was not able to improve LMV. A larger randomized trial with a longer follow-up period may be needed to show changes in LVM in this patient population. Trial registration: this study has been registered at ReBEC (Registro Brasileiro de Ensaios Clinicos) under the identification #RBR-2mzhmj2, available at: https://ensaiosclinicos.gov.br/pesquisador.

Abstract
AbstractIn the early days of peritoneal dialysis (PD) therapy, its limited duration and peritoneal deterioration were argued to be its disadvantages. Biocompatible solutions and hybrid therapy have been used in Japan to overcome these issues, which resulted in a decrease in encapsulating peritoneal sclerosis (EPS) incidence and an extension of PD continuation; these results have been disseminated worldwide. Peritoneal dialysis outcomes and practice patterns study (PDOPPS), a prospective observational study, has begun to confirm the outcomes of PD therapy, and sufficient evidence has been published, which has influenced the preparation of PD guidelines. Current thinking about PD emphasizes the need to maintain quality of life and life goals as care goals for patients and to provide high-quality care. However, we must conduct basic research on the prevention of peritoneal deterioration.

Abstract
BACKGROUND Icodextrin has been shown in randomized controlled trials to benefit fluid management in peritoneal dialysis (PD). We describe international icodextrin prescription practices and their relationship to clinical outcomes. METHODS We analyzed data from the prospective, international PDOPPS, from Australia/New Zealand, Canada, Japan, the United Kingdom, and the United States. Membrane function and 24-hour ultrafiltration according to icodextrin and glucose prescription was determined at baseline. Using an instrumental variable approach, Cox regression, stratified by country, was used to determine any association of icodextrin use to death and permanent transfer to hemodialysis (HDT), adjusted for demographics, comorbidities, serum albumin, urine volume, transplant waitlist status, PD modality, center size, and study phase. RESULTS Icodextrin was prescribed in 1986 (35%) of 5617 patients, >43% of patients in all countries, except in the United States, where it was only used in 17% and associated with a far greater use of hypertonic glucose. Patients on icodextrin had more coronary artery disease and diabetes, longer dialysis vintage, lower residual kidney function, faster peritoneal solute transfer rates, and lower ultrafiltration capacity. Prescriptions with or without icodextrin achieved equivalent ultrafiltration (median 750 ml/d [interquartile range 300-1345 ml/d] versus 765 ml/d [251-1345 ml/d]). Icodextrin use was not associated with mortality (HR=1.03; 95% CI, 0.72 to 1.48) or HDT (HR 1.2; 95% CI, 0.92 to 1.57). CONCLUSIONS There are large national and center differences in icodextrin prescription, with the United States using significantly less. Icodextrin was associated with hypertonic glucose avoidance but equivalent ultrafiltration, which may affect any potential survival advantage or HDT.

Abstract
BACKGROUND The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is an international, prospective study following persons treated by peritoneal dialysis (PD) to identify modifiable practices associated with improvements in PD technique and person survival. The aim of this study was to assess the representativeness of the Australian cohort included in PDOPPS compared to the complete Australian PD population, as reported to the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. METHODS Adults with at least one PD treatment reported to ANZDATA Registry during the census period of PDOPPS Phase I (November 2014 to April 2018) were compared to the Australian PDOPPS cohort. The primary outcomes were the representativeness of centres and persons. Secondary outcomes explored the association of person characteristics with consent to study participation. RESULTS After data linkage, 511 PDOPPS participants were compared to 5616 Australians treated with PD. Within centres eligible for PDOPPS, selected centres were similar to other Australian centres. The PDOPPS participants' cohort tended to include older persons, more males, a higher proportion of Caucasians and more persons with higher socioeconomic advantage compared to the Australian PD population. Differences in distribution across sex and ethnicities between the PDOPPS cohort and the overall PD population were in part due to the selection and consent processes, during which females and non-Caucasians were more likely to not consent to PDOPPS participation. CONCLUSION Sampling methods used in PDOPPS allowed for good national representativeness of the included centres. However, representativeness of the unweighted PDOPPS sample was suboptimal in regard to some participant characteristics.

Abstract
A steadily increasing number of end stage kidney disease (ESKD) patients are maintained on automated peritoneal dialysis (APD) worldwide, in long-standing as well as in more recently established peritoneal dialysis (PD) programs. A better understanding of the technique, paralleled by progress in involved technology, sustained this growth to the point that APD has become the prevalent mode of PD delivery in most high-income countries. While APD is now regarded to be at least as efficient as continuous ambulatory peritoneal dialysis (CAPD) with regard to major biomedical outcomes, its impact on patient-reported outcomes has been less investigated. This paper reviews the main outcomes of APD from a clinical point of view and from the person on dialysis perspective.

A multicenter feasibility randomized controlled trial to assess the impact of incremental versus conventional initiation of hemodialysis on residual kidney function. Kidney Int 2021; 101:615-625. [PMID: 34418414 DOI: 10.1016/j.kint.2021.07.025] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 06/11/2021] [Accepted: 07/15/2021] [Indexed: 12/13/2022]
Abstract
Twice-weekly hemodialysis, as part of incremental initiation, has reported benefits including preservation of residual kidney function (RKF). To explore this, we initiated a randomized controlled feasibility trial examining 55 incident hemodialysis patients with urea clearance of 3 ml/min/1.73 m2 or more across four centers in the United Kingdom randomized to standard or incremental schedules for 12 months. Incremental hemodialysis involved twice-weekly sessions, upwardly adjusting hemodialysis dose as RKF was lost, maintaining total (Dialysis+Renal) Std Kt/V above 2. Standard hemodialysis was thrice weekly for 3.5-4 hours, minimum Dialysis Std Kt/V of 2. Primary outcomes were feasibility parameters and effect size of group differences in rate of loss of RKF at six months. Health care cost impact and patient-reported outcomes were explored. Around one-third of patients met eligibility criteria. Half agreed to randomization; 26 received standard hemodialysis and 29 incremental. At 12 months, 21 incremental patients remained in the study vs 12 in the standard arm with no group differences in the urea clearance slope. Ninety-two percent of incremental and 75% of standard arm patients had a urea clearance of 2 ml/min/1.73 m2 or more at six months. Serious adverse events were less frequent in incremental patients (Incidence Rate Ratio 0.47, confidence interval 0.27-0.81). Serum bicarbonate was significantly lower in incremental patients indicating supplementation may be required. There were three deaths in each arm. Blood pressure, extracellular fluid and patient-reported outcomes were similar. There was no signal of benefit of incremental hemodialysis in terms of protection of RKF or Quality of Life score. Median incremental hemodialysis costs were significantly lower compared to standard hemodialysis. Thus, incremental hemodialysis appears safe and cost-saving in incident patients with adequate RKF, justifying a definitive trial.

Abstract
The recovery of waste glass is an important issue in the fields of social sustainable development and resource recovery. The removal of organic impurity is the first step in the recovery of waste glass. Currently, desiccation-dissociation technology is advised to remove the organic impurity from waste glass. However, the risks of the organic impurity desiccation-dissociation process of waste glass have not been reported in the literature. In this paper, the environmental risks of the organic impurity desiccation-dissociation process of waste glass were assessed. The assessment results indicated that none of TSP (0.143 mg/m3), PM10 (0.090 mg/m3), heavy metals in air and residue after desiccation-dissociation were contaminated. However, the gas contained abundant organic contaminants, especially benzene, whose content was up to 5.26%. Molecular dynamics simulation and contaminant formation pathways analysis indicated that the formation of gaseous organic contaminants was because overmuch small molecular free radicals were generated at 200 °C and combined with each other. Hence, reducing the temperature of desiccation-dissociation, wearing gas masks, and placing organic gas contaminant absorption liquids are necessary protective measures. This paper provides scientific data for the green development of organic impurity desiccation-dissociation technology of waste glass. Meanwhile, this paper makes up for the shortage of the environmental information of the organic impurity desiccation-dissociation of waste glass.

Abstract
BACKGROUND AND OBJECTIVES Survival of peritoneal dialysis (PD) patients in Japan is high, but few reports exist on cause-specific mortality, transfer to haemodialysis (HD) or hybrid dialysis and hospitalisation risks. We aimed to identify reasons for transfer to HD, hybrid dialysis and hospitalisation in the Japan Peritoneal Dialysis and Outcomes Practice Patterns Study. METHODS This observational study included 808 adult PD patients across 31 facilities in Japan in 2014-2017. Information on all-cause and cause-specific mortality and hospitalisation and permanent transfer to HD and PD/HD hybrid therapy were prospectively collected and rates calculated. RESULTS Median follow-up time was 1.66 years where 162 patients transferred to HD, 79 transferred to hybrid dialysis and 74 patients died. All-cause and cardiovascular disease (CVD)-related mortality rates were 5.1 and 1.7 deaths/100 patient-years, respectively. Rates of transfer to HD and hybrid therapy were 11.2 and 5.5 transfers/100 patient-years, respectively. Among HD transfers, 40% were due to infection (including peritonitis), while 20% were due to inadequate solute/water clearance. Eighty-one percent of hybrid dialysis transfers were due to inadequate solute/water clearance. All--cause, peritonitis-related and CVD-related hospitalisation rates were 120.4, 21.1 and 15.6/100 patient-years, respectively. Median hospital length of stay was 19 days. CONCLUSIONS Mortality, hospitalisation and transfer to HD/hybrid dialysis rates are relatively low in Japan compared to many other countries with hybrid transfers, accounting for one-third of dialysis transfers from PD. Further study is needed to explain the high inter-facility variation in hospitalisation rates and how to further reduce hospitalisation rates for Japanese PD patients.

Abstract
BACKGROUND Despite the implementation of a 'Peritoneal Dialysis (PD) First' policy in Thailand since 2008, nationwide PD practices and patients' outcomes have rarely been reported. METHODS As part of the multinational PD Outcomes and Practice Patterns Study (PDOPPS), PD patients from 22 PD centres from different geographic regions, sizes and affiliations, representing Thailand PD facilities, have been enrolled starting in May 2016. Demographic, clinical and laboratory data and patients' outcomes were prospectively collected and analysed. RESULTS The pilot and implementation phases demonstrated excellent concordance between study data and validation data collected at enrolment. In the implementation phase, 848 PD patients (including 262 (31%) incident PD patients) were randomly sampled from 5090 patients in participating centres. Almost all participants (95%) performed continuous ambulatory PD (CAPD), and a high proportion had hypoalbuminemia (67%, serum albumin < 3.5 g/dL), anaemia (42%, haemoglobin <10 g/dL) and hypokalaemia (37%, serum potassium < 3.5 mmol/L). The peritonitis rate was 0.40 episodes/year, but the culture-negative rate was high (0.13 episodes/year, 28% of total episodes). The patients from PD clinics located in Bangkok metropolitan region had higher socio-economic status, more optimal nutritional markers, blood chemistries, haemoglobin level and lower peritonitis rates compared to the provincial regions, emphasizing the centre effect on key success factors in PD. CONCLUSIONS Participation in the PDOPPS helps unveil the critical barriers to improving outcomes of PD patients in Thailand, including a high prevalence of hypokalaemia, anaemia, poor nutritional status and culture-negative peritonitis. These factors should be acted upon to formulate solutions and implement quality improvement on a national level.

Successful treatment with assisted automated peritoneal dialysis using 4.25% glucose dialysate for an elderly patient with refractory heart failure. CEN Case Rep 2020; 10:121-125.

Abstract
Refractory heart failure is a major cause of mortality and hospitalization, and peritoneal dialysis (PD) is one of the options for controlling volume overload. Although high glucose dialysate enables a large amount of ultrafiltration, the use of 4.25% glucose dialysate is generally avoided, because high glucose exposure leads to peritoneal damage. Here, we describe a patient who was successfully treated with assisted automated PD using 4.25% glucose dialysate for refractory heart failure. An 84-year-old woman developed heart failure due to severe mitral regurgitation with a low left-ventricular ejection fraction of 30%, and also developed progressive kidney deterioration. She had been refractory to diuretics and repeatedly hospitalized. PD was started to treat refractory heart failure. Since it was difficult for her to change the dialysis bags by herself, assistance with her PD from her family was needed. The use of 4.25% glucose dialysate markedly increased ultrafiltration and improved her condition. In addition, automated PD (APD) using 4.25% glucose dialysate enabled her family to have a break from PD once every 4 days. Thereafter, she had no episodes of hospitalization due to heart failure for approximately 18 months after her discharge.
