Abstract
Objectives. The results are presented of the 8th National Census (Cs-22) of the Peritoneal Dialysis Project Group of the Italian Society of Nephrology relating to the characteristics of the Centers in Italy which used PD in 2022. Materials and methods. The 227 non-pediatric centers which used Peritoneal Dialysis (PD) in 2022 took part. The data requested were sent in aggregate form. For the first time, the resources available and training were investigated as well as home visits. The Centers have been divided into Quartiles according to the number of prevalent PD patients at 31/12/2022. Results. Centers with a smaller PD program (<9 pts) are characterized by 1. smaller overall size - 2. fewer personnel (doctors/nurses) dedicated to PD - 3. greater recourse to external personnel for training - 4. Less incremental prescription and evaluation of peritoneal permeability - 5. higher drop-out to HD in particular for choice/impossibility to continue and for adequacy/catheter-related issues. A lower peritonitis rate was recorded in Centers with a more extensive PD program (≥25 pts). Home visits are carried out regularly by a small minority of Centers. Conclusions. The analysis shows an association between size of Center PD program and available resources, PD modality and outcome.

Abstract
INTRODUCTION The optimal choice of dialysis modality remains contentious in older adults threatened by advanced age and high risk of comorbidities. METHODS We conducted a systematic review and meta-analysis of cohort and case-control studies to assess mortality risk between peritoneal dialysis (PD) and hemodialysis (HD) in older adults using PubMed, Embase, and the Cochrane Library database from inception to June 1, 2022. The outcome of interest is all-cause mortality. RESULTS Thirty-one eligible studies with >774,000 older patients were included. Pooled analysis showed that PD had a higher mortality rate than HD in older dialysis population (HR 1.17, 95% CI: 1.10-1.25). When stratified by co-variables, our study showed an increased mortality risk of PD versus HD in older patients with diabetes mellitus or comorbidity who underwent longer dialysis duration (more than 3 years) or who started dialysis before 2010. However, definitive conclusions were constrained by significant heterogeneity. CONCLUSION From the survival point of view, caution is needed to employ PD for long-term use in older populations with diabetes mellitus or comorbid conditions. However, a tailored treatment choice needs to take account of what matters to older adults at an individual level, especially in the context of limited survival improvements and loss of quality of life. Further research is still awaited to conclude this topic.

Abstract
Peritonitis is a major cause of morbidity and technique failure in patients receiving peritoneal dialysis. Complicated peritonitis that manifests as multiple or unresolving episodes is classified as refractory, recurrent, relapsing, or repeat peritonitis, and often possesses higher risk of technique failure and mortality as well as lower complete cure rates than primary or uncomplicated episodes. While these peritonitis subtypes affect a considerable portion of PD patients, details regarding their epidemiology, pathogenesis, diagnosis, clinical sequelae, and management have not yet been fully elucidated. Improved clinical awareness and understanding of complicated peritonitis subtypes is crucial to ensure optimal management for these patients; thus, we consolidate and report the pertinent findings of recent literature on these four entities.

Abstract
BACKGROUND Intraperitoneal pressure (IPP) in peritoneal dialysis (PD) is an individual characteristic that can be modified by posture and intraperitoneal volume (IPV). It is considered one of the predisposing factors for complications in the abdominal wall, such as the appearance of hernias. No studies to date have confirmed this. The main aim of this study was to assess the relationship between the development of hernia in incident PD patients and IPP measured at PD onset. METHODS A prospective observational study of incident patients in a PD programme between 2010 and 2020. IPP was measured using the Durand's method. RESULTS One hundred and twenty-four incident patients on PD, 68% male, mean age 62.1 ± 15.23 years, body mass index (BMI) 27.7 ± 4.82 kg/m2, 44% were diabetic. IPP in supine was 16.6 ± 4.60 cm H2O for a mean IPV of 2047.1 ± 359.19 mL. Hernias were reported in 18.5% of patients during PD follow-up: 57% were inguinal hernias, 33% umbilical, and a further 10% presented in a combined form. PD hernias correlated positively with IPP in supine position (p = 0.037), patient age (p = 0.008), BMI (p = 0.043), a history of prior hernia (0.016), laparoscopic catheter placement (p = 0.026), and technique failure (p = 0.012). In the multivariate analysis, a higher IPP was independently related to the development of hernias (p = 0.028). CONCLUSIONS The development of hernias in PD was related to a higher IPP at PD onset, older age, higher BMI, history of prior hernia, catheter placement by laparoscopy, and technique failure.

Abstract
BACKGROUND The most used PD fluids contain glucose as a primary osmotic agent. Glucose peritoneal absorption during dwell decreases the osmotic gradient of peritoneal fluids and causes undesirable metabolic consequences. Inhibitors of sodium-glucose co-transporter (SGLT) type 2 are wildly used for the treatment of diabetes, heart and kidney failure. Previous attempts to use SGLT2 blockers in experimental peritoneal dialysis yielded contrasting results. We studied whether peritoneal SGLTs blockade may improve ultrafiltration (UF) via partial inhibition of glucose uptake from dialysis fluids. METHODS Kidney failure was induced in mice and rats by bilateral ureteral ligation, and dwell was performed by injection of glucose-containing dialysis fluids. The effect of SGLT inhibitors on glucose absorption during fluid dwell and UF was measured in vivo. RESULTS Diffusion of glucose from dialysis fluid into the blood appeared to be sodium-dependent, and blockade of SGLTs by phlorizin and sotagliflozin attenuated blood glucose increment thereby decreasing fluid absorption. Specific SGLT2 inhibitors failed to reduce glucose and fluid absorption from the peritoneal cavity in a rodent kidney failure model. CONCLUSIONS Our study suggests that peritoneal non-type 2 SGLTs facilitate glucose diffusion from dialysis solutions, and we propose that limiting glucose reabsorption by specific SGLT inhibitors may emerge as a novel strategy in PD treatment to enhance UF and mitigate the deleterious effects of hyperglycaemia.

Abstract
There have been significant advances in the understanding of peritoneal dialysis (PD) in the last 40 years, and uptake of PD as a modality of kidney replacement therapy is increasing worldwide. PD fluids, therefore, remains the lifeline for patients on this treatment. Developing these fluids to be efficacious in solute clearance and ultrafiltration, with minimal adverse consequences to peritoneal membrane health and systemic effects is a key requirement. Since the first PD fluid produced in 1959, modifications to PD fluids have been made. Nonetheless, the search for that ideal PD fluid remains elusive. Understanding the components of PD fluids is a key aspect of optimizing the successful delivery of PD, allowing for individualized PD prescription. Glucose remains an integral component of PD fluids; however, its deleterious effects continue to be the impetus for the search of an alternative osmotic agent, and icodextrin remains the main alternative. More biocompatible PD fluids have been developed and have shown benefits in preserving residual kidney function. However, high cost and reduced accessibility remain deterrents to its widespread clinical use in many countries. Large-scale clinical trials are necessary and very much awaited to improve the narrow spectrum of PD fluids available for clinical use.

Abstract
Secondary embedding of a peritoneal dialysis (PD) catheter has been performed for patients whose kidney function has improved enough to stop dialysis but recovery is not expected to be long term. In addition, we have also performed the procedure for patients who have poor general condition due to severe cerebrovascular and/or cardiac disease or who wish to have PD again at the end of life. Here, we report the case of the first terminal haemodialysis (HD) patient who resumed PD using a secondarily embedded catheter as an end-of-life choice. The patient had undergone secondary embedding of a PD catheter and had been transferred to HD, during which time multiple pulmonary metastases of thyroid cancer were observed. She hoped to resume PD in the end-of-life period, and the catheter was subsequently externalised. The catheter was used immediately, and the patient has continued on PD over the past 1 month without infectious or mechanical complications. For elderly end-stage kidney disease patients with progressive disease and cancer, secondary embedding of the PD catheter may be an option to permit them to live the remainder of their lives at home.

Abstract
More and more research has started to investigate the effect of peritoneal dialysis treatment on the incidence of pericatheter wound complications in chronic kidney disease (CKD). This meta-study evaluated the effect of emergency peritoneal dialysis (EPD) with conventional peritoneal dialysis (CPD) in patients with catheter-related complications. We looked up 4 databases: PubMed, EMBASE, Cochrane, and Web of Science, and analysed the data with RevMan 5. There were a total of 15 studies with 3034 participants. While the quality of the research included was fairly good, the evidence was mediocre. In the meta-analyses, the risk of leak in the conduit with PD was very high (OR, 2.48; 95% CI, 1.72, 3.59, p < 0.00001). However, for those treated with urgent medical method prior to initiation of PD, the risk for peritonitis, catheter dysfunction and bleeding was similar compared with CPD. Based on limited information, immediate initiation of PDs is advised in order to increase the quality of life for people in urgent need, except if there is no consideration for loss of fluid. The low quality of the evidence is holding up the evidence. This research, however, is also informative because of the large number of available data. Consequently, additional high quality, large, randomized controlled studies are required to establish.

Abstract
RATIONALE & OBJECTIVE The integrated home dialysis model proposes the initiation of kidney replacement therapy (KRT) with peritoneal dialysis (PD) and a timely transition to home hemodialysis (HHD) after PD ends. We compared the outcomes of patients transitioning from PD to HHD with those initiating KRT with HHD. STUDY DESIGN Observational analysis of the Canadian Organ Replacement Register (CORR). SETTINGS & PARTICIPANTS All patients who initiated PD or HHD within the first 90 days of KRT between 2005 and 2018. EXPOSURE Patients transitioning from PD to HHD (PD+HHD group) versus patients initiating KRT with HHD (HHD group). OUTCOME (1) A composite of all-cause mortality and modality transfer (to in-center hemodialysis or PD for 90 days) and (2) all hospitalizations (considered as recurrent events). ANALYTICAL APPROACH A propensity score analysis for which PD+HHD patients were matched 1:1 to (1) incident HHD patients ("incident-match" analysis) or (2) HHD patients with a KRT vintage at least equivalent to the vintage of PD+HHD patients at the transition time ("vintage-matched" analysis). Cause-specific hazards models (composite outcome) and shared frailty models (hospitalization) were used to compare groups. RESULTS Among 63,327 individuals in the CORR, 163 PD+HHD patients (median of 1.9 years in PD) and 711 HHD patients were identified. In the incident-match analysis, compared to the HHD patients, the PD+HHD group had a similar risk of the composite outcome (HR, 0.88 [95% CI, 0.58-1.32]) and hospitalizations (HR, 1.04 [95% CI, 0.76-1.41]). In the vintage-match analysis, PD+HHD patients had a lower hazard for the composite outcome (HR, 0.61 [95% CI, 0.40-0.94]) but a similar hospitalization risk (HR, 0.85 [95% CI, 0.59-1.24]). LIMITATIONS Risk of survivor bias in the PD+HHD cohort and residual confounding. CONCLUSIONS Controlling for KRT vintage, the patients transitioning from PD to HHD had better clinical outcomes than the incident HHD patients. These data support the use of integrated home dialysis for patients initiating home-based KRT. PLAIN-LANGUAGE SUMMARY The integrated home dialysis model proposes the initiation of dialysis with peritoneal dialysis (PD) and subsequent transition to home hemodialysis (HHD) once PD is no longer feasible. It allows patients to benefit from initial lifestyle advantages of PD and to continue home-based treatments after its termination. However, some patients may prefer to initiate dialysis with HHD from the outset. In this study, we compared the long-term clinical outcomes of both approaches using a large Canadian dialysis register. We found that both options led to a similar risk of hospitalization. In contrast, the PD-to-HHD model led to improved survival when controlling for the duration of kidney failure.

Abstract
BACKGROUND Minimally invasive surgery has been used for both de novo insertion and salvage of peritoneal dialysis (PD) catheters. Advanced laparoscopic, basic laparoscopic, open, and image-guided techniques have evolved as the most popular techniques. The aim of this guideline was to develop evidence-based guidelines that support surgeons, patients, and other physicians in decisions on minimally invasive peritoneal dialysis access and the salvage of malfunctioning catheters in both adults and children. METHODS A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons reviewed the literature since the prior guideline was published in 2014 and developed seven key questions in adults and four in children. After a systematic review of the literature, by the panel, evidence-based recommendations were formulated using the Grading of Recommendations Assessment, Development and Evaluation approach. Recommendations for future research were also proposed. RESULTS After systematic review, data extraction, and evidence to decision meetings, the panel agreed on twelve recommendations for the peri-operative performance of laparoscopic peritoneal dialysis access surgery and management of catheter dysfunction. CONCLUSIONS In the adult population, conditional recommendations were made in favor of: staged hernia repair followed by PD catheter insertion over simultaneous and traditional start over urgent start of PD when medically possible. Furthermore, the panel suggested advanced laparoscopic insertion techniques rather than basic laparoscopic techniques or open insertion. Conditional recommendations were made for either advanced laparoscopic or image-guided percutaneous insertion and for either nonoperative or operative salvage. A recommendation could not be made regarding concomitant clean-contaminated surgery in adults. In the pediatric population, conditional recommendations were made for either traditional or urgent start of PD, concomitant clean or clean-contaminated surgery and PD catheter placement rather than staged, and advanced laparoscopic placement rather than basic or open insertion.

Abstract
BACKGROUND An ideal technique for peritoneal dialysis (PD) catheter insertion should provide a long-term functioning catheter until permanent renal replacement therapy becomes available. We developed a technique using the nephroscope-assisted single-trocar approach in 2011. In this study, we report the outcomes, learning curve analysis and cost-effectiveness analysisof the nephroscopic approach compared with the traditional laparoscopic approach. METHOD Between January 2005 and December 2020, we retrospectively reviewed 511 patients who received PD catheter insertions using the laparoscopic or nephroscopic approach. We compared the baseline characteristics of the patients, surgical outcomes, and complications of the two groups. We further analyzed the nephroscopic group to determine the cost-effectiveness analysis, learning curve and the complication frequency between the learning and mastery periods of the nephroscopic approach. RESULTS A total of 208 patients underwent laparoscopic PD catheter insertion, whereas 303 patients received nephroscopic surgery. The median catheter survival in the nephroscopic group is significantly longer (43.1 vs. 60.5 months, p = 0.019). The incidence of peritonitis (29.3% vs.20.8%, p = 0.035) and exit site infection (12.5% vs. 6.6%, p = 0.019) were significantly lower in the nephroscopic group. The cost-effectiveness analysis showed a medical expense reduction of 16000 USD annually by using the nephroscopic technique. There was no difference in the frequency of surgical complications between the learning and mastery phases when examining the learning curve analysis for the nephroscopic technique. CONCLUSIONS Compared with the traditional laparoscopic approach, the nephroscopic technique effectively prolonged catheter survival and reduces health care cost by reducing infectious complications. The low complication rate during the learning phase of surgery makes the procedure safe for patients and surgeons.

Abstract
There are a significant number of mechanical complications related the peritoneal dialysis (PD) catheter and early diagnosis is key. Between them, the spontaneous extrusion of the catheter is quite uncommon but it should be included among the possible complications of the technique, given that it can be related to frequent situations in PD patients like abdominal wall issues, past immunosuppression or PD fluid leakage. In 25 years our Unit had three cases, probably related to peritoneal fluid leakage, exit site infection and past steroid treatment. Careful examination of abdominal wall preimplantation, adequate break-in period to allow maturation and early detection of exit site infection to start treatment in a timely fashion could help to prevent this rare complication. The complete extrusion of the catheter does not preclude from continuing PD treatment.

Abstract
Peritoneal dialysis (PD) catheter is the lifeline of PD patients, and despite the overall strength of the PD program in many countries, PD catheter survival remains the major weakness of the program. The prompt and effective implantation of the PD catheter, as well as speedy management of complications arising from catheter insertion, remains crucial for the success of the program.

Abstract
SIGNIFICANCE STATEMENT The Advancing American Kidney Health Initiative aims to increase rates of utilization of peritoneal dialysis (PD) in the United States. One of the first steps to PD is successful catheter placement, which can be performed by surgeons, interventional radiologists, or nephrologists. We examined the association between operator subspecialty and risk of needing a follow-up procedure in the first 90 days after initial PD catheter implantation. Overall, we found that 15.5% of catheters required revision, removal, or a second catheter placement within 90 days. The odds of requiring a follow-up procedure was 36% higher for interventional radiologists and 86% higher for interventional nephrologists compared with general surgeons. Further research is needed to understand how to optimize the function of catheters across different operator types. BACKGROUND The US government has implemented incentives to increase the use of PD. Successful placement of PD catheters is an important step to increasing PD utilization rates. Our objective was to compare initial outcomes after PD catheter placement by different types of operators. METHODS We included PD-naïve patients insured by Medicare who had a PD catheter inserted between 2010 and 2019. We examined the association between specialty of the operator (general surgeon, vascular surgeon, interventional radiologist, or interventional nephrologist) and odds of needing a follow-up procedure, which we defined as catheter removal, replacement, or revision within 90 days of the initial procedure. Mixed logistic regression models clustered by operator were used to examine the association between operator type and outcomes. RESULTS We included 46,973 patients treated by 5205 operators (71.1% general surgeons, 17.2% vascular surgeons, 9.7% interventional radiologists, 2.0% interventional nephrologists). 15.5% of patients required a follow-up procedure within 90 days of the initial insertion, of whom 2.9% had a second PD catheter implanted, 6.6% underwent PD catheter removal, and 5.9% had a PD catheter revision within 90 days of the initial insertion. In models adjusted for patient and operator characteristics, the odds of requiring a follow-up procedure within 90 days were highest for interventional nephrologists (HR, 1.86; 95% confidence interval [CI], 1.56 to 2.22) and interventional radiologists (odds ratio, 1.36; 95% CI, 1.17 to 1.58) followed by vascular surgeons (odds ratio, 1.06; 95% CI, 0.97 to 1.14) compared with general surgeons. CONCLUSIONS The probability of needing a follow-up procedure after initial PD catheter placement varied by operator specialty and was higher for interventionalists and lowest for general surgeons.

Abstract
INTRODUCTION Peritoneal dialysis (PD) is home-based dialysis therapy and therefore a suitable modality for kidney failure patients, particularly, during the COVID-19 pandemic. The present study examined patients' preferences for different PD-related services. METHODS This was a cross-sectional survey study. Anonymized data from PD patients followed up at a single center in Singapore were collected using an online platform. The study focused on telehealth services, home visits, and monitoring of quality-of-life (QoL). RESULTS A total of 78 PD patients responded to the survey. The majority of participants were Chinese (76%), married (73%), and between 45 and 65 years old (45%). The in-person visit was preferred over teleconsultation for consultation with nephrologists (68% versus 32%), counseling for kidney disease and dialysis by renal coordinators (59%), whereas the telehealth service was favored over in-person visit for dietary counseling (60%) and medication counseling (64%). Most participants (81%) preferred medication delivery over self-collection, and the acceptable turnaround time was 1 week. Sixty percent would like to have a regular home visit, but 23% refused such visits. The preferred frequency of home visits was one-to-three visits within the first 6 months (74%) and then 6 monthly for subsequent visits (40%). The majority of participants (87%) agreed with QoL monitoring, and the preferred frequency of monitoring varied between 6 monthly (45%) and yearly (40%). Participants also indicated three key areas in research to improve QoL, such as the development of artificial kidneys, portable PD devices, and simplification of PD procedure. Participants also would like to see improvement in two main areas of PD services, such as delivery service for PD solutions and social (instrumental, informational, and emotional) support. CONCLUSIONS Most PD patients preferred in-person visits with nephrologists or renal coordinators; however, they favored telehealth services with dieticians and pharmacists. PD patients also welcomed home visit service and QoL monitoring. Future studies should confirm these findings.

Abstract
Home hemodialysis (HD) and automated peritoneal dialysis (APD) have advantages over HD in hospitals or HD centers. Home therapies are generally less expensive and give patients greater mobility and freedom for work, school, family, and recreational activities. Technological advances have made it possible to complement APD with devices for remote monitoring (RM) of the patient. With them, objective information generated in the APD device is collected and sent to repositories "in the cloud" for analysis or at the time decided by the health team. With APD+RM, it is possible to monitor therapeutic compliance, effective dialysis time, ultrafiltration volumes, inflow and outflow patterns of dialysis fluid, and patient actions to respond to alarms that indicate deviations from the parameters set by the nephrologist. The results of APD+RM show good acceptance by the patient, nephrologists, and nurses, treatment adherence has improved, hospitalizations and technique failure have decreased, and some aspects of quality of life have improved. However, there is a lack of controlled clinical trials that reliably demonstrate lower mortality and comorbidity due to specific causes.

Abstract
BACKGROUND Peritoneal dialysis provides several benefits for patients and should be offered as first line kidney replacement therapy, particularly for fragile patients. Limitation to self-care drove assisted peritoneal dialysis to evolve from family-based care to institutional programs, with specialized care givers. Some European countries have mastered this, while others are still bound by the availability of a volunteer to become responsible for treatment. METHODS A group of leading nephrologists from 13 European countries integrated real-life application of such therapy, highlighting barriers, lessons learned and practical solutions. The objective of this work is to share and summarize several different approaches, with their intrinsic difficulties and solutions, which might helpperitoneal dialysis units to develop and offer assisted peritoneal dialysis. RESULTS Assisted peritoneal dialysis does not mean 4 continuous ambulatory peritoneal dialysis exchanges, 7 days/week, nor does it exclude cycler. Many different prescriptions might work for our patients. Tailoring PD prescription to residual kidney function, thereby maintaining small solute clearance, reduces dialysis burden and is associated with higher technique survival. Assisted peritoneal dialysis does not mean assistance will be needed permanently, it can be a transitional stage towards individual or caregiver autonomy. Private care agencies can be used to provide assistance; other options may involve implementing PD training programs for the staff of nursing homes or convalescence units. Social partners may be interested in participating in smaller initiatives or for limited time periods. CONCLUSION Assisted peritoneal dialysis is a valid technique, which should be expanded. In countries without structural models of assisted peritoneal dialysis, active involvement by the nephrologist is needed in order for it to become a reality.

Abstract
BACKGROUND Peritonitis is a common cause of hospitalisation and death among patients undergoing peritoneal dialysis. Periodic retraining is recommended to prevent peritonitis, especially in older adults. OBJECTIVES We evaluated the effectiveness of a retraining programme for reducing peritonitis and exit site infection rates in older adults on peritoneal dialysis. The cost-benefit ratio was also calculated. DESIGN A two-arm prospective randomised controlled trial. PARTICIPANTS One hundred and thirty patients aged 55 years or older were recruited. Participants were randomly assigned to the intervention or control group. While both groups received usual care, the intervention group received a retraining programme (a knowledge and practical assessment and a one-on-one retraining session) 90 days after starting home-based continuous ambulatory peritoneal dialysis therapy. MEASUREMENTS The outcomes included peritonitis rate, exit site infection rate and direct medical costs at 180, 270, and 360 days after starting home-based continuous ambulatory peritoneal dialysis therapy. RESULTS No significant differences were found in the baseline characteristics between groups. The peritonitis rates were 0.11 episodes per patient-year in the intervention group versus 0.13 in the control group. The incidence of exit site infection was 20.0% in the intervention group and 12.3% in the control group. The cost-benefit ratio of retraining was 1:9.6. None of the results were statistically significant. CONCLUSIONS The absence of statistical significance may be partly explained by the premature termination of the study. Large-scale multi-centre trials are warranted to examine the effectiveness of retraining. The timing and long-term effects of retraining also need to be examined.

Abstract
BACKGROUND Residual kidney function (RKF) impacts patients' survival rate and quality of life when undergoing peritoneal dialysis (PD). This meta-analysis was conducted to systematically identify risk and protective factors associated with RKF decline and loss. METHODS We searched three English and one Chinese databases from inception to January 31, 2023, for cohort and cross-sectional studies exploring factors associated with RKF decline or loss. The random effects model was employed to aggregate risk estimates and 95% confidence intervals (CIs) from multivariate analysis. Sensitivity and subgroup analyses were performed to explore the heterogeneity among the studies. RESULTS Twenty-seven studies comprising 13549 individuals and 14 factors were included in the meta-analysis. Based on the meta-analysis results, risk factors involving male gender (hazard ratio (HR) 1.689, 95%CI 1.385-2.061), greater body mass index (BMI) (odds ratio (OR) 1.081, 95% confidence interval (CI) 1.029-1.135), higher systolic blood pressure (SBP) (HR 1.014, 95%CI 1.005-1.024), diabetes mellitus (DM) (HRRKF loss 1.873, 95%CI 1.475-2.378), DM (ORRKF decline 1.906, 95%CI 1.262-2.879), peritonitis (relative ratio (RR) 2.291, 95%CI 1.633-3.213), proteinuria (OR 1.223, 95%CI 1.117-1.338), and elevated serum phosphorus (RR 2.655, 95%CI 1.679-4.201) significantly contributed to the risk of RKF decline and loss in PD patients. Conversely, older age (HR 0.968, 95%CI 0.956-0.981), higher serum albumin (OR 0.834, 95%CI 0.720-0.966), weekly Kt/V urea (HR 0.414, 95%CI 0.248-0.690), baseline urine volume (UV) (HR 0.791, 95%CI 0.639-0.979), baseline RKF (HR 0.795, 95%CI 0.739-0.857) exhibited protective effects. However, diuretics use, automatic peritoneal dialysis (APD) modality and baseline RKF did not significantly impact RKF decline. CONCLUSIONS Patients with male gender, greater BMI, higher SBP, DM, peritonitis, proteinuria, and elevated serum phosphorus might have a higher risk of RKF decline and loss. In contrast, older age, higher serum albumin, weekly Kt/V urea, baseline UV, and baseline RKF might protect against RKF deterioration.

Abstract
Bacterial infections and the concurrent inflammation have been associated with increased long-term cardiovascular (CV) risk. In patients receiving peritoneal dialysis (PD), bacterial peritonitis is a common occurrence, and each episode further increases late CV mortality risk. However, the underlying mechanism(s) remains to be elucidated before safe and efficient anti-inflammatory interventions can be developed. Damage-Associated Molecular Patterns (DAMPs) have been shown to contribute to the acute inflammatory response to infections, but a potential role for DAMPs in mediating long-term vascular inflammation and CV risk following infection resolution in PD, has not been investigated. We found that bacterial peritonitis in mice that resolved within 24h led to CV disease-promoting systemic and vascular immune-mediated inflammatory responses that were maintained up to 28 days. These included higher blood proportions of inflammatory leukocytes displaying increased adhesion molecule expression, higher plasma cytokines levels, and increased aortic inflammatory and atherosclerosis-associated gene expression. These effects were also observed in infected nephropathic mice and amplified in mice routinely exposed to PD fluids. A peritonitis episode resulted in elevated plasma levels of the DAMP Calprotectin, both in PD patients and mice, here the increase was maintained up to 28 days. In vitro, the ability of culture supernatants from infected cells to promote key inflammatory and atherosclerosis-associated cellular responses, such as monocyte chemotaxis, and foam cell formation, was Calprotectin-dependent. In vivo, Calprotectin blockade robustly inhibited the short and long-term peripheral and vascular consequences of peritonitis, thereby demonstrating that targeting of the DAMP Calprotectin is a promising therapeutic strategy to reduce the long-lasting vascular inflammatory aftermath of an infection, notably PD-associated peritonitis, ultimately lowering CV risk.

Abstract
Despite comparable outcomes with the extracorporeal dialysis modalities, peritoneal dialysis (PD) is seldom considered a viable option for managing acute kidney injury (AKI) in developed and resource-rich countries, where continuous renal replacement therapies (CRRTs) are the mainstay of treating AKI. PD has fewer infrastructure requirements and has been shown to save lives during conflicts, natural disasters, and pandemics. During the ongoing COVID-19 pandemic, the developed world was confronted with a sudden surge in critically ill AKI patients requiring renal replacement therapy. There were acute shortages of CRRT machines and the trained staff to deliver those treatments. Some centres developed acute PD programmes to circumvent these issues with good results. This experience re-emphasised the suitability of PD for managing AKI. It also highlighted the need to review the current management strategies for AKI in developed countries and consider incorporating PD as a viable tool for suitable patients. This article reviews the current evidence of using PD in AKI, attempts to clarify some misconceptions about PD in AKI, and argues in favour of developing acute PD programmes.

Abstract
BACKGROUND This multi-institutional, observational study examined whether the outcomes after peritoneal dialysis (PD) catheter placement in Japan meet the audit criteria of the International Society for Peritoneal Dialysis (ISPD) guideline and identified factors affecting technique survival and perioperative complications. METHODS Adult patients who underwent first PD catheter placement for end-stage kidney disease between April 2019 and March 2021 were followed until PD withdrawal, kidney transplantation, transfer to other facilities, death, 1 year after PD start or March 2022, whichever came first. Primary outcomes were time to catheter patency failure and technique failure, and perioperative infectious complications within 30 days of catheter placement. Secondary outcomes were perioperative complications. Appropriate statistical analyses were performed to identify factors associated with the outcomes of interest. RESULTS Of the total 409 patients, 8 who underwent the embedded catheter technique did not have externalised catheters. Of the 401 remaining patients, catheter patency failure occurred in 25 (6.2%). Technical failure at 12 months after PD catheter placement calculated from cumulative incidence function was 15.3%. On Cox proportional hazards model analysis, serum albumin (hazard ratio (HR) 0.44; 95% confidence interval (CI) 0.27-0.70) and straight type catheter (HR 2.14; 95% CI 1.24-3.69) were the independent risk factors for technique failure. On logistic regression analysis, diabetes mellitus was the only independent risk factor for perioperative infectious complications (odds ratio 2.70, 95% CI 1.30-5.58). The occurrence rate of perioperative complications generally met the audit criteria of the ISPD guidelines. CONCLUSION PD catheter placement in Japan was proven to be safe and appropriate.

Abstract
Background: Peritoneal dialysis (PD) is a frequent method for renal replacement therapy in pediatric population. However, PD is associated with a high incidence of early and late complications. Thus, this study aims to evaluate the perioperative factors associated with these complications. Methods: Clinical records of patients who had peritoneal dialysis catheter (PDC) placement between January 2013 and June 2016 were retrospectively analyzed. Sociodemographic and perioperative variables were recorded and analyzed. Results: A total of 92 patients required PDC insertion. Primary PDC failure occurred in 21.74% of cases, and 17.39% required reoperation. The most common complication was occlusion (13.04%), followed by leak (8.7%). Age younger than 1 year and weight less than 10 kg were significant risk factors for catheter dysfunction, reoperation, leak, PDC occlusion, hernia, and death. The open technique was associated with higher risks of operation, leak, and peritonitis than the laparoscopic technique. Placement of the catheter by the laparoscopic technique reduced the odds of occlusion by 38%. Conclusions: Patients younger than 1 year and weighing less than 10 kg have an increased risk of complications and death, regardless of the technique used. The most frequent complication is catheter failure; however, the laparoscopic technique appears to reduce this complication.

Abstract
Peritoneal dialysis is a reliable and effective treatment for end-stage kidney disease. However, inadequate catheter insertion can lead to mechanical dysfunction, which remains an unresolved problem. In this study, we present the initial results of a modified laparoscopic approach. This study included 38 patients who underwent peritoneal dialysis using a modified laparoscopic approach. During the procedure, a single laparoscopic trocar was employed, and peritoneal entry was performed using a percutaneous pull-apart sheath/dilator. To minimize the risk of complications, the free catheter portion was kept short in the peritoneum. The modified method was guided by proven recommendations of the standard laparoscopic technique. The mean operation time was recorded as 24.28 ± 15.5. The mean hospitalization was found to be 1.20 ± 0.72 days. The postoperative morbidity was 26.3%. The mechanical dysfunction rate was 5.26%. The median follow-up time was 20.4 ± 17.14 months. The median peritoneal dialysis catheter-free survival was 25.96 ± 4.02 months. The catheter-free survival rate was 92.11%. The modified laparoscopic approach has been demonstrated to be a safe and effective option, and initial studies have indicated that it offers several benefits over traditional methods, including a straightforward procedure with a brief duration, minimal complications, and brief hospital stay.

Abstract
Objective: Peritoneal dialysis (PD) requires high patient conscientiousness. Therefore, we aimed to investigate the relationship between conscientiousness score and prognosis in PD patients.Methods: The ten-item Big Five Personality Inventory's Chinese version was used to assess the conscientiousness score. Basic clinical information, prior medical history, hematological examination results, the occurrence of the first peritonitis and catheter-related infection, the start of hemodialysis, and the time of renal transplantation were collected. The patients were split into two groups, high and low conscientiousness groups, based on the mean value of the conscientiousness score. The differences in prognostic indicators were compared between groups, and the association between conscientiousness score and prognostic indicators in PD patients was assessed.Results: Enrolled PD patients were divided into low conscientiousness group 103 and high conscientiousness group 98. There were significant differences in serum albumin (p = 0.021) and iPTH (p = 0.045) between the two groups. Multivariate Cox regression analysis identified conscientiousness score as an independent risk factor for the development of first peritonitis (HR = 0.558, 95% CI 0.400-0.779, p = 0.001) and first catheter-related infection (HR = 0.544, 95% CI 0.308-0.962, p = 0.036) in PD patients. Conscientiousness score (HR = 2.377, 95% CI 1.109-5.095, p = 0.026) was independently associated with renal transplantation.Conclusion: Conscientiousness personality is closely related to the prognosis of PD patients.
