Abstract
BACKGROUND Laparoscopic techniques are being widely applied for peritoneal dialysis (PD) catheter (PDC) placement. The suture passer is a novel fixation tool that aims to reduce catheter migration. We compared the clinical value of the suture passer combined with two-hole laparoscopic PDC placement to open surgical placement by evaluating preoperative and postoperative conditions, as well as the onset of complications in both groups. METHODS A retrospective study was conducted including 169 patients who underwent PDC placement surgery from January 2021 to May 2023. Based on the method employed, patients were divided into two groups: the suture passer combined with a two-hole laparoscopy group (SLG) and the open surgical group (SG). Comprehensive patient information, including general data, preoperative and postoperative indicators, peritoneal function after surgery, and the incidence rate of complications, were collected and analyzed. RESULTS The SLG showed a statistically significant decrease in operative time, intraoperative blood loss, and 6-month postoperative drift rate compared to the SG (p < 0.05). No statistically significant differences were observed between the two groups in terms of sex, age, primary disease, hospitalization time, hospitalization costs, preoperative and postoperative examination indicators, peritonitis, and omental wrapping. CONCLUSIONS Suture passer combined with two-hole laparoscopic PDC placement, characterized by simplicity and facilitating secure catheter fixation, was deemed safe and effective for patients undergoing PD. It reduces the catheter migration rate and improved surgical comfort. Overall, this technique demonstrates favorable outcomes in clinical practice.

Lu C, Cheng S, Fan W, Zhang Z, Wang J. The relationship of platelet distribution width with all-cause and cardiovascular mortality in peritoneal dialysis patients. Ren Fail 2024; 46:2300730. [PMID: 38343320 PMCID: PMC10863511 DOI: 10.1080/0886022x.2023.2300730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 12/26/2023] [Indexed: 02/15/2024] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is a major complication in peritoneal dialysis (PD) patients. Previous studies have demonstrated that platelet distribution width (PDW) is associated with cardiovascular events in hemodialysis (HD) patients. In this study, we hypothesized that elevated PDW can predict all-cause and cardiovascular mortality in PD patients. METHODS We recruited PD patients for a single-center retrospective cohort study from 1 January 2007, to 30 June 2020. Receiver-operating characteristic (ROC) curves were made to determine the PDW cutoff value for predicting all-cause mortality. The propensity score matching (PSM) method was used to improve the equilibrium between groups. The relation of PDW with all-cause and cardiovascular mortality was analyzed by Cox proportional hazards models. Restricted cubic spline (RCS) models were used to determine whether there was a linear relationship between PDW and all-cause and cardiovascular mortality. RESULTS A total of 720 PD patients were screened, and 426 PD patients were enrolled after PSM. After adjusting for confounders, Cox proportional hazards models showed that the PDW value was positively correlated with the risk of all-cause and cardiovascular mortality (HR = 1.162, 95% CI 1.057-1.278, p = 0.002 and HR = 1.200, 95% CI 1.041-1.382, p = 0.012). The adjusted RCS analysis further showed that the relationship of PDW with all-cause and cardiovascular mortality was linear (p for nonlinearly = 0.143 and 0.062). CONCLUSION Elevated PDW is independently associated with all-cause and cardiovascular mortality in PD patients.

Ren Fail 2024; 46:2312535. [PMID: 38321869 PMCID: PMC10851793 DOI: 10.1080/0886022x.2024.2312535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/27/2024] [Indexed: 02/08/2024] Open
Abstract
BACKGROUND The potential impact of elevated intra-abdominal pressure (IAP) on residual renal function (RRF) has not been determined. The objective of this study was to investigate the relationship between IAP and the rate of RRF decline in newly initiated peritoneal dialysis (PD) patients, and to identify the optimal IAP threshold value for delaying the deterioration of RRF. METHODS A cohort of 62 newly initiated PD patients who completed both 6- and 12-month follow-up evaluations was obtained using the Durand method. A logistic regression model was used to identify variables associated with a rapid decline in RRF. Receiver operating characteristic (ROC) curves were generated to determine the optimal threshold value. Another retrospective cohort analysis was performed to validate the identified critical value. RESULTS For each 1 cmH2O increase in IAP, the risk of a rapid decline in the RRF increased by a factor of 1.679. Subsequent analysis revealed that patients in the high IAP group had more significant decreases in residual renal estimated glomerular filtration rate (eGFR) (Z = -3.694, p < 0.001) and urine volume (Z = -3.121, p < 0.001) than did those in the non-high IAP group. Furthermore, an IAP ≥15.65 cmH2O was a robust discriminator for the prediction of the rate of RRF decline. CONCLUSION Patients in the high IAP group experienced a more rapid decline in RRF. Additionally, an optimal critical pressure of 15.65 cmH2O was identified for predicting the rate of RRF decline. IAP, as one of the factors contributing to the rapid decline in RRF in the first year of PD, should be given due attention.

Abstract
BACKGROUND Peritonitis is a common and serious complication of peritoneal dialysis and is one of the main causes of peritoneal dialysis technique failure and long-term hemodialysis conversion. OBJECTIVES The aim of the review was to identify and clarify peritonitis risk factors and learn about strategies employed at international level to prevent and reduce the occurrence of peritoneal dialysis associated infections and their complications. DESIGN A scoping review. PARTICIPANTS Adults in pertitoneal dialysis. MEASUREMENTS The methodology framework of Arksey and O'Malley and PRISMA for Scoping Reviews guidelines were applied. A search was conducted of PubMed, Scopus and CINAHL using terms to identify peritoneal dialysis -associated risk factors and interventions carried out for the prevention and reduction of peritonitis in adult persons living at home. RESULTS The 17 studies selected were based on work carried out in nine different countries. Eleven articles analysed modifiable risk factors (low educational level, being a foreigner and low adherence to aseptic technique) and non-modifiable risk factors (age and comorbidities) that predispose to peritonitis in peritoneal dialysis. The other six studies applied an intervention to improve the prevalence of peritonitis considering educational practices adapted to patient characteristics and the application of retraining. CONCLUSIONS Personalised patient training and the identification of risk factors for peritonitis are key to reducing complications and enhancing the survival of peritoneal dialysis patients and the effectiveness of the technique.

Abstract
RATIONALE & OBJECTIVE Reasons for transfer from peritoneal dialysis (PD) to hemodialysis (HD) remain incompletely understood. Among incident and prevalent patients receiving PD, we evaluated the association of clinical factors, including prior treatment with HD, with PD technique survival. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS Adults who initiated PD at a Dialysis Clinic, Inc (DCI) outpatient facility between January 1, 2010, and September 30, 2019. EXPOSURE The primary exposure of interest was timing of PD start, categorized as PD-first, PD-early, or PD-late. Other covariates included demographics, clinical characteristics, and routine laboratory results. OUTCOME Modality switch from PD to HD sustained for more than 90 days. ANALYTICAL APPROACH Multivariable Fine-Gray models with competing risks and time-varying covariates, stratified at 9 months to account for lack of proportionality. RESULTS Among 5,224 patients who initiated PD at a DCI facility, 3,174 initiated dialysis with PD ("PD-first"), 942 transitioned from HD to PD within 90 days ("PD-early"), and 1,108 transitioned beyond 90 days ("PD-late"); 1,472 (28%) subsequently transferred from PD to HD. The PD-early and PD-late patients had a higher risk of transfer to HD as compared with PD-first patients (in the first 9 months: adjusted hazard ratio [AHR], 1.51 [95% CI, 1.17-1.96] and 2.41 [95% CI, 1.94-3.00], respectively; and after 9 months: AHR, 1.16 [95% CI, 0.99-1.35] and AHR, 1.43 [95% CI, 1.24-1.65], respectively). More peritonitis episodes, fewer home visits, lower serum albumin levels, lower residual kidney function, and lower peritoneal clearance calculated with weekly Kt/V were additional risk factors for PD-to-HD transfer. LIMITATIONS Missing data on dialysis adequacy and residual kidney function, confounded by short PD technique survival. CONCLUSIONS Initiating dialysis with PD is associated with greater PD technique survival, though many of those who initiate PD-late in their dialysis course still experience substantial time on PD. Peritonitis, lower serum albumin, and lower Kt/V are risk factors for PD-to-HD transfer that may be amenable to intervention. PLAIN-LANGUAGE SUMMARY Peritoneal dialysis (PD) is an important kidney replacement modality with several potential advantages compared with in-center hemodialysis (HD). However, a substantial number of patients transfer to in-center HD early on, without having experienced the quality-of-life and other benefits that come with sustained maintenance of PD. Using retrospective data from a midsize national dialysis provider, we found that initiating dialysis with PD is associated with longer maintenance of PD, compared with initiating dialysis with HD and a later switch to PD. However, many of those who initiate PD-late in their dialysis course still experience substantial time on PD. Peritonitis, lower serum albumin, and lower small protein removal are other risk factors for PD-to-HD transfer that may be amenable to intervention.

Abstract
BACKGROUND Dialysis is lifesaving for acute kidney injury (AKI), but access is poor in less resourced settings. A "peritoneal dialysis (PD) first" policy for paediatric AKI is more feasible than haemodialysis in low-resource settings. METHODS Retrospective review of modalities and outcomes of children dialysed acutely at Red Cross War Memorial Children's Hospital between 1998 and 2020. RESULTS Of the 593 children with AKI who received dialysis, 463 (78.1%) received PD first. Median age was 9.0 (range 0.03-219.3; IQR 13.0-69.6) months; 57.6% were < 1 year old. Weights ranged from 0.9 to 2.0 kg (median 7.0 kg, IQR 3.0-16.0 kg); 38.6% were < 5 kg. PD was used more in younger children compared to extracorporeal dialysis (ECD), with median ages 6.4 (IQR 0.9-30.4) vs. 73.9 (IQR 17.5-113.9) months, respectively (p = 0.001). PD was performed with Seldinger soft catheters (n = 480/578, 83%), predominantly inserted by paediatricians at the bedside (n = 412/490, 84.1%). Complications occurred in 127/560 (22.7%) children receiving PD. Overall, 314/542 (57.8%) children survived. Survival was significantly lower in neonates (< 1 month old, 47.5%) and infants (1-12 months old, 49.2%) compared with older children (> 1 year old, 70.4%, p < 0.0001). Survival was superior in the ECD (75.4%) than in the PD group (55.6%, p = 0.002). CONCLUSIONS "PD First for Paediatric AKI" is a valuable therapeutic approach for children with AKI. It is feasible in low-resourced settings where bedside PD catheter insertion can be safely taught and is an acceptable dialysis modality, especially in settings where children with AKI would otherwise not survive.

Sodium removal per ultrafiltration volume in automated peritoneal dialysis in pediatric patients. Pediatr Nephrol 2024; 39:2753-2758. [PMID: 38695892 DOI: 10.1007/s00467-024-06383-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 04/13/2024] [Accepted: 04/15/2024] [Indexed: 07/26/2024]
Abstract
BACKGROUND The standard rate of sodium removal in adult anuric patients on continuous ambulatory peritoneal dialysis (CAPD) is 7.5 g/L of ultrafiltration volume (UFV). Although automated PD (APD) is widely used in pediatric patients, no attempt has yet been made to estimate sodium removal in APD. METHODS The present, retrospective cohort study included pediatric patients with APD who were managed at Tokyo Metropolitan Children's Medical Center between July 2010 and November 2017. The patients underwent a peritoneal equilibrium test (PET) at our hospital. Sodium removal per UFV was calculated by peritoneal function and dwell time using samples from patients on APD with 1- and 2-h dwell effluent within three months of PET and 4- and 10-h dwell effluent at PET. RESULTS In total, 217 samples from 18 patients were included, with 63, 81, and 73 of the samples corresponding to the High [H], High-average [HA], and Low-average [LA] PET category, respectively. Sodium removal per UFV (g/L in salt equivalent) for dwell times of one, two, four, and ten hours was 5.2, 8.8, 8.0, and 11.5 for PET [H], 5.3, 5.8, 5.6, and 8.1 for PET [HA], and 4.6, 5.1, 5.1, and 7.1 for PET [LA], respectively. CONCLUSIONS Sodium removal per UFV in pediatric APD was less than the standard adult CAPD and tended to be lower with shorter dwell times, leading to sodium accumulation. Therefore, salt intake should be restricted in combination with one or more long daytime dwells, especially in anuric patients.

Abstract
BACKGROUND Effective peritoneal dialysis (PD) training is essential for performing dialysis at home and reducing the risk of peritonitis and other PD-related infections. Virtual reality (VR) is an innovative learning tool that is able to combine theoretical information, interactivity, and behavioral instructions while offering a playful learning environment. To improve patient training for PD, Fresenius Medical Care launched the stay•safe MyTraining VR, a novel educational program based on the use of a VR headset and a handheld controller. OBJECTIVE This qualitative assessment aims to investigate opinions toward the new tool among the health care professionals (HCPs) who were responsible for implementing the VR application. METHODS We recruited nursing staff and nephrologists who have gained practical experience with the stay•safe MyTraining VR within pilot dialysis centers. Predetermined open-ended questions were administered during individual and group video interviews. RESULTS We interviewed 7 HCPs who have 2 to 20 years of experience in PD training. The number of patients trained with the stay•safe MyTraining VR ranged from 2 to 5 for each professional. The stay•safe MyTraining VR was well accepted and perceived as a valuable supplementary tool for PD training. From the respondents' perspective, the technology improved patients' learning experience by facilitating the internalization of both medical information and procedural skills. HCPs highlighted that the opportunity offered by VR to reiterate training activities in a positive and safe learning environment, according to each patient's needs, can facilitate error correction and implement a standardized training curriculum. However, VR had limited use in the final phase of the patient PD training program, where learners need to get familiar with the handling of the materials. Moreover, the traditional PD training was still considered essential to manage the emotional and motivational aspects and address any patient-specific application-oriented questions. In addition to its use within PD training, VR was perceived as a useful tool to support the decision-making process of patients and train other HCPs. Moreover, VR introduction was associated with increased efficiency and productivity of HCPs because it enabled them to perform other activities while the patient was practicing with the device. As for patients' acceptance of the new tool, interviewees reported positive feedback, including that of older adults. Limited use with patients experiencing dementia or severe visual impairment or lacking sensomotoric competence was mentioned. CONCLUSIONS The stay•safe MyTraining VR is suggested to improve training efficiency and efficacy and thus could have a positive impact in the PD training scenario. Our study offers a process proposal that can serve as a guide to the implementation of a VR-based PD training program within other dialysis centers. Dedicated research is needed to assess the operational benefits and the consequences on patient management.

Abstract
End-stage renal disease (ESRD) patients are at increased risk of mortality, particularly due to cardiovascular events such as acute myocardial infarction. Hemodialysis and peritoneal dialysis are the two main treatment modalities for ESRD patients. Using data from the National Inpatient Sample (NIS) database, we conducted a retrospective study involving 25,435 ESRD patients diagnosed with ST-elevation myocardial infarction (STEMI) between 2016 and 2020, categorized by their dialysis regimen. Our analysis revealed comparable mortality rates between peritoneal dialysis (PD) and hemodialysis (HD) patients, but lower hospitalization costs and fewer complications among PD recipients. Over five years, we observed a notable decrease in STEMI mortality despite increased STEMI cases among HD patients. Conversely, HD patients experienced increased hospital stays and associated costs over the study period than PD patients, who demonstrated stable trends. This study highlights the implications of dialysis modality selection in managing costs and reducing morbidity among STEMI patients with ESRD.

Abstract
RATIONALE & OBJECTIVE A history of prior abdominal procedures may influence the likelihood of referral for peritoneal dialysis (PD) catheter insertion. To guide clinical decision making in this population, this study examined the association between prior abdominal procedures and outcomes in patients undergoing PD catheter insertion. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS Adults undergoing their first PD catheter insertion between November 1, 2011, and November 1, 2020, at 11 institutions in Canada and the United States participating in the International Society for Peritoneal Dialysis North American Catheter Registry. EXPOSURE Prior abdominal procedure(s) defined as any procedure that enters the peritoneal cavity. OUTCOMES The primary outcome was time to the first of (1) abandonment of the PD catheter or (2) interruption/termination of PD. Secondary outcomes were rates of emergency room visits, hospitalizations, and procedures. ANALYTICAL APPROACH Cumulative incidence curves were used to describe the risk over time, and an adjusted Cox proportional hazards model was used to estimate the association between the exposure and primary outcome. Models for count data were used to estimate the associations between the exposure and secondary outcomes. RESULTS Of 855 patients who met the inclusion criteria, 31% had a history of a prior abdominal procedure and 20% experienced at least 1 PD catheter-related complication that led to the primary outcome. Prior abdominal procedures were not associated with an increased risk of the primary outcome (adjusted HR, 1.12; 95% CI, 0.68-1.84). Upper-abdominal procedures were associated with a higher adjusted hazard of the primary outcome, but there was no dose-response relationship concerning the number of procedures. There was no association between prior abdominal procedures and other secondary outcomes. LIMITATIONS Observational study and cohort limited to a sample of patients believed to be potential candidates for PD catheter insertion. CONCLUSION A history of prior abdominal procedure(s) does not appear to influence catheter outcomes following PD catheter insertion. Such a history should not be a contraindication to PD. PLAIN-LANGUAGE SUMMARY Peritoneal dialysis (PD) is a life-saving therapy for individuals with kidney failure that can be done at home. PD requires the placement of a tube, or catheter, into the abdomen to allow the exchange of dialysis fluid during treatment. There is concern that individuals who have undergone prior abdominal procedures and are referred for a catheter might have scarring that could affect catheter function. In some institutions, they might not even be offered PD therapy as an option. In this study, we found that a history of prior abdominal procedures did not increase the risk of PD catheter complications and should not dissuade patients from choosing PD or providers from recommending it.

Abstract
BACKGROUND This study aims to examine the treatment patterns of end-stage kidney disease (ESKD) among SLE patients and to compare the outcome of hemodialysis (HD) and peritoneal dialysis (PD). METHODS SLE patients identified from the national administration dataset in 2005-2021 were linked to the Australia and New Zealand Dialysis and Transplant Registry to identify ESKD cases. The adjusted odds ratio of having PD instead of HD as the first treatment for ESKD for Asian, Māori, and Pacific compared with European/others was estimated with the logistic regression model. The adjusted hazards ratio of all-cause mortality for patients having PD first compared with HD first was calculated. RESULTS Two hundred ten ESKD patients with SLE were identified. Two thirds (137/210) of the ESKD patients had HD as the first treatment, and one third (68, 32.4%) had PD first. Around 60% of Asian patients had PD as the first treatment, compared with 30% in other ethnic groups. The adjusted odds ratio of having PD as the first treatment for Asian patients compared with European/others was 3.00 (95% confidence interval, 1.16-7.73). The adjusted hazards ratio of all-cause mortality for patients in the PD group compared with the HD group was 0.60 (95% confidence interval, 0.37-0.97). CONCLUSIONS Asian patients with ESKD were more likely to have PD as the first treatment. The optimal dialysis type for ESKD patients with SLE might be different from ESKD patients caused by other diseases. ESKD patients with SLE receiving PD first had superior outcomes than patients receiving HD first.

Abstract
BACKGROUND The impact of different pretransplant dialysis modalities on post-transplant outcomes for pancreas-kidney transplantation is currently unclear. This study aims to assess the association between pretransplant dialysis modalities [hemodialysis (HD) and peritoneal dialysis] and outcomes following pancreas-kidney transplantation. METHODS The authors searched PubMed, EMBASE, and the Cochrane Library for relevant studies published from inception until 1 December 2023. The authors included studies that examined the relationship between pretransplant dialysis modalities and clinical outcomes for pancreas-kidney transplantation. The primary outcomes considered were patient, pancreas and kidney graft survival, and intra-abdominal infection. RESULTS A total of 13 studies involving 1503 pancreas-kidney transplant recipients were included. Pretransplant HD was associated with improved pancreas graft survival (hazard ratio = 0.71, 95% confidence interval: 0.51-0.99, I ²=12%) and a decreased risk of intra-abdominal infection [odds ratio (OR)=0.69, 95% CI: 0.51-0.93, I ²=5%). However, no significant association was found between the dialysis modalities and patient or kidney graft survival. Furthermore, pretransplant HD was linked to a reduced risk of anastomotic leak (OR=0.32, 95% CI: 0.161-0.68, I ²=0%) and graft thrombosis (OR=0.56, 95% CI: 0.33-0.96, I ²=20%). CONCLUSION Pretransplant HD is the preferred dialysis modality while awaiting pancreas-kidney transplantation, although well-designed prospective studies are needed to confirm these findings.

Abstract
INTRODUCTION United States Military operations in resource limited areas are increasing. Furthermore, future peer or near-peer conflicts will require caring for larger numbers of casualties with limited resources. In this setting, traditional renal replacement therapy is not feasible and novel methods are required to address severe acute kidney injury in austere environments lacking definitive therapies. Here, we describe experiments designed to determine the efficacy of a novel peritoneal packing material (Potassium Binding Pack-PBP, CytoSorbents INC) for the acute management of severe hyperkalemia. MATERIALS AND METHODS Male swine (52 ±1 kg) were nephrectomized via midline laparotomy under a plane of anesthesia and randomized into one of two experimental groups (PBP & CON). Exogenous potassium was infused to achieve a serum potassium level of 7.5 mEq/L. Novel potassium absorbing packs (PBP) or sham packs (CON) were placed in the right and left upper quadrants, and the right and left paracolic gutters of the abdomen to simulate four-quadrant packing (n = 6, n = 5, respectively). Two liters of peritoneal dialysis fluid was instilled into the abdomen and temporary closure performed. Animals were observed for 12 hours. Serum and peritoneal fluid (dialysate) potassium levels were sampled at T = 15, 30, 60 min, and Q60min thereafter. Animals were humanely euthanized at the end of the observation period. RESULTS Baseline characteristics were similar between groups. Pairwise analysis showed that serum potassium concentrations were significantly lower in the PBP group compared to CON at T = 540 and T = 720 (P = 0.006 and P = 0.015, respectively). Potassium concentrations were significantly lower in dialysate of the PBP group compared to CON at all time points after T = 15 (T = 30, P = 0.017; T = 60 through T = 720, P < 0.001). CONCLUSIONS This is the first demonstration of an effective technology for the management of hyperkalemia in trauma in the absence of standard of care; renal replacement therapy. We identified that PBP was able to consistently maintain a concentration gradient between dialysate in the peritoneum and system potassium concentration throughout the experiment. Furthermore, systemic potassium concentrations were reduced in a clinically relevant manner in the PBP group compared to CON. This suggests that peritoneal packing technology for the management of metabolic disturbances in trauma has potential for clinical application. These results are preliminary and should be interpreted with caution.

Abstract
There are various dialysis methods available to treat patients with chronic kidney failure. Generally, a distinction is made between peritoneal dialysis and hemodialysis, as well as between home dialysis methods and center-based dialysis methods. To be able to advise patients optimally, it is important to understand the opportunities and limitations of the different method variants. This article provides an overview of the therapy options and describes their strengths and weaknesses.

Abstract
BACKGROUND Patients with advanced chronic kidney disease have lower health-related quality of life (HRQOL) than the general population. There is uncertainty regarding patterns of HRQOL changes before dialysis initiation. This study aimed to characterise HRQOL trajectory and assess its potential association with intended dialysis modality. METHODS This prospective single-centre cohort study followed adults with an estimated glomerular filtration rate ≤15 mL/min/1.73 m2 for one year. Patients were allocated into one of two groups based on their intended treatment modality, 'home dialysis' (peritoneal dialysis or home haemodialysis (HD)) and 'other' (in-centre HD or conservative care). Follow-up was for up to 1 year or earlier if initiated on kidney replacement therapy or died. Kidney Disease Quality of Life - Short Form (KDQOL-SF) was completed every 6 months. Predictors of changes in KDQOL-SF components were modelled using mixed effect multivariable linear regressions. RESULTS One hundred and nine patients were included. At baseline, crude physical composite summary (PCS) (45 ± 10 vs. 39 ± 8) was higher in patients choosing home dialysis (n = 41), while mental composite summary (MCS) was similar in both groups. After adjustment, patients choosing home dialysis had an increase in MCS (B = 8.4 per year, p = 0.007) compared to those selecting in-centre HD/conservative care. This translates into an annual increase in MSC by 3 points for the 'home dialysis' group, compared to an annual decline by 5.4 points in the 'other' group. There was no difference in PCS trajectory through time. CONCLUSIONS Patients choosing home dialysis had improved MCS over time compared to those not selecting home dialysis. More work is needed to determine how differences in processes of care and/or unmeasured patient characteristics modulate this association.

Abstract
INTRODUCTION Patients with end-stage renal disease (ESRD) frequently change renal replacement (RRT) therapy modality due to medical or social reasons. We aimed to evaluate the outcomes of patients under peritoneal dialysis (PD) according to the preceding RRT modality. METHODS We conducted a retrospective observational single-center study in prevalent PD patients from January 1, 2010, to December 31, 2017, who were followed for 60 months or until they dropped out of PD. Patients were divided into three groups according to the preceding RRT: prior hemodialysis (HD), failed kidney transplant (KT), and PD-first. RESULTS Among 152 patients, 115 were PD-first, 22 transitioned from HD, and 15 from a failing KT. There was a tendency for ultrafiltration failure to occur more in patients transitioning from HD (27.3% vs. 9.6% vs. 6.7%, p = 0.07). Residual renal function was better preserved in the group with no prior RRT (p < 0.001). A tendency towards a higher annual rate of peritonitis was observed in the prior KT group (0.70 peritonitis/year per patient vs. 0.10 vs. 0.21, p = 0.065). Thirteen patients (8.6%) had a major cardiovascular event, 5 of those had been transferred from a failing KT (p = 0.004). There were no differences between PD-first, prior KT, and prior HD in terms of death and technique survival (p = 0.195 and p = 0.917, respectively) and PD efficacy was adequate in all groups. CONCLUSIONS PD is a suitable option for ESRD patients regardless of the previous RRT and should be offered to patients according to their clinical and social status and preferences.

Abstract
PURPOSE Immediate-start peritoneal dialysis (PD) has emerged as a strategy for patients in need of urgent dialysis. However, the ideal timing for initiating this procedure remains uncertain. In this study, we aimed to compare complications and outcomes between immediate-start PD and conventional-start PD. METHODS We performed a two-center retrospective cohort study between 1 January 2015 and 31 May 2020. Patients who underwent PD were divided into immediate-start PD (without break-in period) and conventional-start PD group (break-in period within at least 14 days). The primary outcomes were the incidence of the mechanical complications and infectious complication. The secondary outcomes were technique failure and patient survival. RESULTS A total of 209 patients (106 in the immediate-start PD group and 103 in the conventional-start PD group) were included. Immediate-start PD had significantly lower catheter malfunction or migration rate compare with conventional-start PD (2.8% vs. 15.5%, p = 0.003) but comparable rates of dialysate leaks, pleuroperitoneal leaks, and hemoperitoneum. Infectious complications (exit-site infection and peritonitis) were similar between groups. Technique survival was comparable (7.5% vs. 4.8%, p = 0.22), while immediate-start PD exhibited lower mortality rates (0.9% vs. 13.6%, p = 0.001). CONCLUSION Immediate-start PD appears to be a viable option for patients in need of urgent dialysis, with reduced catheter complications and comparable infectious complications and technique survival when compared to conventional-start PD.

Abstract
The increasing burden of haemodialysis on healthcare systems merits efforts to make peritoneal dialysis (PD) more accessible to the population in need of kidney replacement therapy. Automated PD (APD) may be a suitable alternative to continuous ambulatory peritoneal dialysis for home dialysis especially for children, elderly and patients who lead a busy schedule in their jobs thus leaving more time for personal and family activities during the day. Recently, a local bioengineering company took the initiative to develop a locally manufactured, low-cost APD cycler in Pakistan, with an aim to improve the self-dependency and home-based kidney replacement therapy. We herein present our first experience of APD on this locally manufactured APD cycler. It was an investigator-led study on the utility of a locally manufactured APD cycler and the safety and efficacy of the standard operating procedures developed and adopted by the study authors. A total of eight patients agreed to participate in this study extending from September 2021 to August 2022. There were four male and four female patients, and the mean age was 52.5 + 19.71 years. The locally manufactured cycler provided more than 1600 h of APD sessions. The APD sessions were well tolerated with only a few instances of minor mechanical and software issues that did not require termination of therapy. There were no episodes of peritonitis; however, one of the patients had an episode of exit site and tunnel infection that did not seem to be related to the procedure. Our experience with locally manufactured APD cycler was successful and without major adverse events. We believe the locally produced APD cycler is a viable cost-effective option for patients requiring PD and may herald a new era of self-dependency for patients considering or undergoing PD in Pakistan.

Abstract
BACKGROUND Peritoneal dialysis (PD) and haemodialysis (HD) are two possible modalities for people with kidney failure commencing dialysis. Only a few randomised controlled trials (RCTs) have evaluated PD versus HD. The benefits and harms of the two modalities remain uncertain. This review includes both RCTs and non-randomised studies of interventions (NRSIs). OBJECTIVES To evaluate the benefits and harms of PD, compared to HD, in people with kidney failure initiating dialysis. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies from 2000 to June 2024 using search terms relevant to this review. Studies in the Register were identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov. MEDLINE and EMBASE were searched for NRSIs from 2000 until 28 March 2023. SELECTION CRITERIA RCTs and NRSIs evaluating PD compared to HD in people initiating dialysis were eligible. DATA COLLECTION AND ANALYSIS Two investigators independently assessed if the studies were eligible and then extracted data. Risk of bias was assessed using standard Cochrane methods, and relevant outcomes were extracted for each report. The primary outcome was residual kidney function (RKF). Secondary outcomes included all-cause, cardiovascular and infection-related death, infection, cardiovascular disease, hospitalisation, technique survival, life participation and fatigue. MAIN RESULTS A total of 153 reports of 84 studies (2 RCTs, 82 NRSIs) were included. Studies varied widely in design (small single-centre studies to international registry analyses) and in the included populations (broad inclusion criteria versus restricted to more specific participants). Additionally, treatment delivery (e.g. automated versus continuous ambulatory PD, HD with catheter versus arteriovenous fistula or graft, in-centre versus home HD) and duration of follow-up varied widely. The two included RCTs were deemed to be at high risk of bias in terms of blinding participants and personnel and blinding outcome assessment for outcomes pertaining to quality of life. However, most other criteria were assessed as low risk of bias for both studies. Although the risk of bias (Newcastle-Ottawa Scale) was generally low for most NRSIs, studies were at risk of selection bias and residual confounding due to the constraints of the observational study design. In children, there may be little or no difference between HD and PD on all-cause death (6 studies, 5752 participants: RR 0.81, 95% CI 0.62 to 1.07; I2 = 28%; low certainty) and cardiovascular death (3 studies, 7073 participants: RR 1.23, 95% CI 0.58 to 2.59; I2 = 29%; low certainty), and was unclear for infection-related death (4 studies, 7451 participants: RR 0.98, 95% CI 0.39 to 2.46; I2 = 56%; very low certainty). In adults, compared with HD, PD had an uncertain effect on RKF (mL/min/1.73 m2) at six months (2 studies, 146 participants: MD 0.90, 95% CI 0.23 to 3.60; I2 = 82%; very low certainty), 12 months (3 studies, 606 participants: MD 1.21, 95% CI -0.01 to 2.43; I2 = 81%; very low certainty) and 24 months (3 studies, 334 participants: MD 0.71, 95% CI -0.02 to 1.48; I2 = 72%; very low certainty). PD had uncertain effects on residual urine volume at 12 months (3 studies, 253 participants: MD 344.10 mL/day, 95% CI 168.70 to 519.49; I2 = 69%; very low certainty). PD may reduce the risk of RKF loss (3 studies, 2834 participants: RR 0.55, 95% CI 0.44 to 0.68; I2 = 17%; low certainty). Compared with HD, PD had uncertain effects on all-cause death (42 studies, 700,093 participants: RR 0.87, 95% CI 0.77 to 0.98; I2 = 99%; very low certainty). In an analysis restricted to RCTs, PD may reduce the risk of all-cause death (2 studies, 1120 participants: RR 0.53, 95% CI 0.32 to 0.86; I2 = 0%; moderate certainty). PD had uncertain effects on both cardiovascular (21 studies, 68,492 participants: RR 0.96, 95% CI 0.78 to 1.19; I2 = 92%) and infection-related death (17 studies, 116,333 participants: RR 0.90, 95% CI 0.57 to 1.42; I2 = 98%) (both very low certainty). Compared with HD, PD had uncertain effects on the number of patients experiencing bacteraemia/bloodstream infection (2 studies, 2582 participants: RR 0.34, 95% CI 0.10 to 1.18; I2 = 68%) and the number of patients experiencing infection episodes (3 studies, 277 participants: RR 1.23, 95% CI 0.93 to 1.62; I2 = 20%) (both very low certainty). PD may reduce the number of bacteraemia/bloodstream infection episodes (2 studies, 2637 participants: RR 0.44, 95% CI 0.27 to 0.71; I2 = 24%; low certainty). Compared with HD; It is uncertain whether PD reduces the risk of acute myocardial infarction (4 studies, 110,850 participants: RR 0.90, 95% CI 0.74 to 1.10; I2 = 55%), coronary artery disease (3 studies, 5826 participants: RR 0.95, 95% CI 0.46 to 1.97; I2 = 62%); ischaemic heart disease (2 studies, 58,374 participants: RR 0.86, 95% CI 0.57 to 1.28; I2 = 95%), congestive heart failure (3 studies, 49,511 participants: RR 1.10, 95% CI 0.54 to 2.21; I2 = 89%) and stroke (4 studies, 102,542 participants: RR 0.94, 95% CI 0.90 to 0.99; I2 = 0%) because of low to very low certainty evidence. Compared with HD, PD had uncertain effects on the number of patients experiencing hospitalisation (4 studies, 3282 participants: RR 0.90, 95% CI 0.62 to 1.30; I2 = 97%) and all-cause hospitalisation events (4 studies, 42,582 participants: RR 1.02, 95% CI 0.81 to 1.29; I2 = 91%) (very low certainty). None of the included studies reported specifically on life participation or fatigue. However, two studies evaluated employment. Compared with HD, PD had uncertain effects on employment at one year (2 studies, 593 participants: RR 0.83, 95% CI 0.20 to 3.43; I2 = 97%; very low certainty). AUTHORS' CONCLUSIONS The comparative effectiveness of PD and HD on the preservation of RKF, all-cause and cause-specific death risk, the incidence of bacteraemia, other vascular complications (e.g. stroke, cardiovascular events) and patient-reported outcomes (e.g. life participation and fatigue) are uncertain, based on data obtained mostly from NRSIs, as only two RCTs were included.

Abstract
Despite numerous studies on the effect of each dialysis modality on mortality, the issue remains controversial. We investigated the hazard rate of mortality in patients with incident end-stage renal disease (ESRD) concerning initial dialysis modality (hemodialysis vs. peritoneal dialysis). Using a nationwide, multicenter, prospective cohort in South Korea, we studied 2207 patients, of which 1647 (74.6%) underwent hemodialysis. We employed the weighted Fine and Gray model over the follow-up period using inverse probability of treatment and censoring weighting. Landmark analysis was used for identifying the changing effect of dialysis modality on individuals who remained event-free at each landmark point. No significant difference in hazard rate was observed overall. However, the peritoneal dialysis group had a significantly higher hazard rate than the hemodialysis group among patients under 65 years after 4- and 5- year follow-up. A similar pattern was observed among those with diabetes mellitus. Landmark analysis also showed the higher hazard rate for peritoneal dialysis at 2 years for the education-others group and at 3 years for the married group. These findings may inform dialysis modality decisions, suggesting a preference for hemodialysis in young patients with diabetes, especially for follow-ups longer than 3 years.

Abstract
BACKGROUND Lipoprotein (a) [Lp(a)] is associated with atherosclerosis and cardiovascular mortality in patients with kidney failure. Aortic stiffness (AS), measured primarily by carotid-femoral pulse wave velocity (cfPWV), reflects vascular aging and precedes end-organ failure. This study aimed to evaluate the association between serum Lp(a) levels and cfPWV in patients undergoing peritoneal dialysis (PD). MATERIAL AND METHODS In this cross-sectional study, which included 148 patients with long-term PD for end-stage kidney failure, cfPWV was measured using a cuff-based method. AS was defined as a cfPWV exceeding 10 m/s, and an enzyme-linked immunosorbent assay was used to determine serum Lp(a) levels. Univariate and multivariate regression analyses were performed to identify the clinical correlates of AS. RESULTS There were 32 (21.6%) patients diagnosed with AS. Based on the multivariate logistic regression analysis, the odds ratio for AS was 1.007 (95% confidence interval, 1.003-1.011; P=0.001) for every 1 mg/L increase in Lp(a) levels. Multivariate linear regression analysis showed that Lp(a) (P<0.001), age (P=0.003), waist circumference (P=0.008), systolic blood pressure (P=0.010), and diabetes mellitus (P<0.001) were positively associated with cfPWV. The area under the receiver operating characteristic curve for Lp(a) in differentiating AS from non-AS was 0.770 (95% confidence interval, 0.694-0.835; P<0.0001). CONCLUSIONS Serum Lp(a) level was independently associated with cfPWV and AS in patients with PD.

Abstract
The most common kidney replacement therapy (KRT) worldwide is hemodialysis (HD), and only 5%-10% of patients are prescribed peritoneal dialysis (PD) as KRT. Despite PD being a different method, these patients also present particular complications, such as oxidative stress, gut dysbiosis, premature aging, and mitochondrial dysfunction, leading to an inflammation process and high cardiovascular mortality risk. Although recent studies have reported nutritional strategies in patients undergoing HD with attempts to mitigate these complications, more information must be needed for PD patients. Therefore, this review provides a comprehensive analysis of recent studies of nutritional intervention to mitigate inflammation in PD patients.

Abstract
OBJECTIVES The objective of this Prospective Register of Systematic Reviews (CRD42022384192) registered systematic review and meta-analysis was to determine whether prophylactic peritoneal dialysis (PD) catheter insertion at the time of pediatric cardiac surgery is associated with improved short-term outcomes. DATA SOURCES Databases search of the MEDLINE, EMBASE, CINAHL, and Cochrane Library completed in April 2021 and updated October 2023. STUDY SELECTION Two reviewers independently completed study selection, data extraction, and bias assessment. Inclusion criteria were randomized controlled trials (RCTs) and observational studies of children (≤ 18 yr) undergoing cardiac surgery with cardiopulmonary bypass. We evaluated use of prophylactic PD catheter versus not. DATA EXTRACTION The primary outcome was in-hospital mortality, as well as secondary short-term outcomes. Pooled random-effect meta-analysis odds ratio with 95% CI are reported. DATA SYNTHESIS Seventeen studies met inclusion criteria, including four RCTs. The non-PD catheter group received supportive care that included diuretics and late placement of PD catheters in the ICU. Most study populations included children younger than 1 year and weight less than 10 kg. Cardiac surgery was most commonly used for arterial switch operation. In-hospital mortality was reported in 13 studies; pooled analysis showed no association between prophylactic PD catheter placement and in-hospital mortality. There were mixed results for ICU length of stay and time to negative fluid balance, with some studies showing shortened duration associated with use of prophylactic PD catheter insertion and others showing no difference. Overall, the studies had high risk for bias, mainly due to small sample size and lack of generalizability. CONCLUSIONS In this meta-analysis, we have failed to demonstrate an association between prophylactic PD catheter insertion in children and infants undergoing cardiac surgery and reduced in-hospital mortality. Other relevant short-term outcomes, including markers of fluid overload, require further study.
