Abstract
Life participation requiring physical activity and physical function is a key patient-reported outcome for people receiving peritoneal dialysis (PD). Clinician guidance is required from multidisciplinary sources regarding exercise and activity advice to address the specific needs of this group. From August 2020 through to June 2021, the Global Renal Exercise Network and the International Society for Peritoneal Dialysis reviewed the published literature and international clinical experience to develop a set of clinical practice points. A set of questions relevant to physical activity and exercise were developed from the perspective of a person receiving PD and were the basis for the practice point development. The GRADE framework was used to evaluate the quality of evidence and to guide clinical practice points. The review of the literature found sparse quality evidence, and thus the clinical practice points are generally based on the expert consensus of people receiving PD, PD exercise expert clinicians and experienced PD exercise researchers. Clinical practice points address timing of exercise and activity (post-catheter insertion, peritoneal space empty or full), the uptake of specific activities (work, sex, swimming, core exercise), potential adverse outcomes related to activity and exercise (exit site care, perspiration, cardiovascular compromise, fatigue, intra-abdominal pressure), the effect of exercise and activity on conditions of interest (mental health, obesity, frailty, low fitness) and exercise nutrition.

Abstract
Non-diphtheria corynebacteria species cause disease in risk populations such as immunocompromised patients and patients with indwelling medical devices. Despite reports of exit-site infection and peritonitis caused by non-diphtheria corynebacteria, these organisms are frequently dismissed as contaminants. During a 10-year observation period, we prospectively identified 8 cases of exit-site/tunnel infections caused by 2 different species of corynebacteria ( Corynebacterium striatum in 5 and C. jeikeium in 3 cases). Four patients experienced a second episode of exit-site infection 3 months (2 cases), 25 months, and 40 months, respectively, after termination of an oral cephalosporin therapy of 4 to 6 weeks’ duration. Non-diphtheria corynebacteria accounted for 9% of all exit-site infections during the study period. All catheter-related infections healed; no catheter had to be removed. The diagnosis of catheter-related non-diphtheria corynebacteria infection may be suspected when Gram stain shows gram-positive rods and with colony morphology and commercial biochemical identification systems. Susceptibility of non-diphtheria corynebacteria to antibiotics may vary, especially in C. jeikeium. Virtually all Corynebacterium species are sensitive to vancomycin. Empirical antibiotic therapy with vancomycin should be initiated while antibiotic susceptibility testing is being carried out. Oral cephalosporin may be an alternative treatment regimen for exit-site infections if sensitive. This study highlights the importance of non-diphtheria corynebacteria as emerging nosocomial pathogens in the population of end-stage renal disease patients on on continuous ambulatory peritoneal dialysis.

Archaeal tetraether lipid coatings-A strategy for the development of membrane analog spacer systems for the site-specific functionalization of medical surfaces. Biointerphases 2018; 13:011004.

Abstract
The primary goal of our investigation was the development of a versatile immobilization matrix based on archaeal tetraether lipids that meets the most important prerequisites to render an implant surface bioactive by binding specific functional groups or functional polymers with the necessary flexibility and an optimal spatial arrangement to be bioavailable. From this point of view, it appears obvious that numerous efforts made recently to avoid initial bacterial adhesion on catheter surfaces as an important prerequisite of material associated infection episodes have shown only a limited efficiency since the bioactive entities could not be presented in an optimal conformation and a stable density. A significant improvement of this situation can be achieved by highly specific biomimetic modifications of the catheter surfaces. The term "biomimetic" originates from the fact that specific archaeal tetraether lipids were introduced to form a membrane analog monomolecular spacer system, which (1) can be immobilized on nearly all solid surfaces and (2) chemically modified to present a tailor-made functionality in contact with aqueous media either to avoid or inhibit surface fouling or to equip any implant surface with the necessary chemical functionality to enable cell adhesion and tissue integration. Ultrathin films based on tetraether lipids isolated from archaea Thermoplasma acidophilum were used as a special biomimetic immobilization matrix on the surface of commercial medical silicon elastomers. A complete performance control of the membrane analog coatings was realized in addition to biofunctionality tests, including the proof of cytotoxicity and hemocompatibility according to DIN EN ISO 10993. In order to make sure that the developed immobilization matrix including the grafted functional groups are biocompatible under in vivo-conditions, specific animal tests were carried out to examine the in vivo-performance. It can be concluded that the tetraether lipid based coating systems on silicone have shown no signs of cytotoxicity and a good hemocompatibility. Moreover, no mutagenic effects, no irritation effects, and no sensitization effects could be demonstrated. After an implantation period of 28 days, no irregularities were found.

Abstract
Peritoneal dialysis (PD) represents a treatment opportunity for patients with end-stage renal failure, but it has particular complications that sometimes force cessation of this procedure (1–9). These complications are due to the presence of the peritoneal catheter and of dialysis solution within the peritoneal cavity. Infections are the most common complications of PD, followed by mechanical complications. Diagnostic imaging of the complications of PD is important because such an evaluation can aid in the diagnosis and in the decision making process about the treatment. In this review we present the main radiologic investigations employed: plain radiograph, US, peritoneography, computed tomography peritoneography, magnetic resonance peritoneography, peritoneal scintigraphy. To diagnose catheter-related problems plain radiograph, ultrasonography and peritoneography can be useful. US is useful in diagnosing and following-up exit-site and tunnel infections. Peritoneography and C T-peritoneography, alone or in combination, can be recommended as gold standard investigation to assess mechanical peritoneal dialysis complications, such as catheter malfunction, leaks, hernias and sclerosing peritonitis. Newer methods, such as MR peritoneography or scintigraphy could be useful in selected patients, on center-based experience. An appropriate use of radiology may significantly improve technique survival, morbidity and mortality of patients treated with PD.

Abstract
Hemodialysis catheter associated infections are a major source of morbidity and mortality in end stage renal disease patients. There is disagreement about the management of catheter infections, particularly concerning the removal of potentially infected tunneled dialysis catheters. A dialysis catheter should generally be removed when an infection involves a temporary hemodialysis catheter, a septic patient, a patient with a tunnel tract infection, or a patient with evidence of a metastatic infectious complication. In treating stable patients with clinically mild catheter associated bacteremia, parenteral antibiotics alone have a low success rate in eliminating the infection. Antibiotic locks are an emerging strategy for treating these patients, but at present higher rates of success and lower costs are achieved by exchanging the catheter over a guidewire. Antibiotic lock solutions, antibiotic coated catheters, and totally implantable dialysis access systems may play a large role in prevention of catheter associated infections in the future; however, further randomized controlled trials of these strategies are needed. Future efforts should concentrate on limiting the use of traditional tunneled cuffed hemodialysis catheters by early referral to vascular surgery for the creation of an arterio-venous fistula.

Abstract
OBJECTIVE The objective of our research was to summarize and review evidence supporting a causal relationship between exit-site infection and peritonitis in peritoneal dialysis (PD) patients. DATA SOURCES We undertook a qualitative review of studies retrieved from MEDLINE, EMBASE, and PubMed, and supplemented that process with a hand search of references and abstracts in the literature. STUDY SELECTION Our quality criteria were based on the Paediatric Risk of Mortality guidelines, definitions, and recommendations from the International Society for Peritoneal Dialysis (ISPD), and the Bradford Hill criteria for causality. All identified abstracts were reviewed for content. Of 776 abstracts, 59 were selected for full-text evaluation, and 22 of those met the ISPD criteria for good-quality research in PD-related infections. Of the 22 eligible studies, 9 met the study's quality criteria and were included in the summative analysis. No articles reported sufficient data for a quantitative analysis. DATA EXTRACTION Information on study design, study population characteristics, definitions, peritonitis rates, exit-site care protocol, exit-site treatment protocol, follow-up period, potential bias, and outcomes was extracted. Criteria for including data in the final study were determined using ISPD guidelines. DATA SYNTHESIS Of the 9 included studies, 8 suggested that a history of exit-site infection increased the risk for subsequent peritonitis. Of those studies, 3 met 5 causality criteria, 4 met 4 causality criteria, and 1 met 3 causality criteria. CONCLUSIONS The literature provides weak evidence to support a causal relationship between exit-site infection and subsequent peritonitis. Few criteria for causation were met. We were unable to attribute causation and could assume an association only. The exclusion of studies focusing on PD-related tunnel infections may be viewed as both a strength and a limitation of the present work.

Abstract
INTRODUCTION Peritoneal dialysis via Tenckhoff catheter predisposes to hernia formation due to both local and systemic factors. Another important complication of peritoneal catheter insertion includes infection, which can prompt removal of the catheter. METHODS We performed a retrospective study between January 2005 and July 2011 of 61 patients who underwent laparoscopic placement of a Tenckhoff catheter and peritoneal dialysis at our institution using a single-port technique. We analysed complications of Tenckhoff insertion, specifically infection and the formation of hernias requiring operative management. RESULTS Infections noted in our patients included peritonitis (10%) and exit-site infection (5%). Of the five patients who required re-insertion of Tenckhoff catheter, four were for infective complications. A total of seven hernias developed in five (8%) of patients, mostly inguinal or umbilical near the Hassan port entry site. DISCUSSION With infection and hernia formation being the main contributors to failure of the procedure, actively addressing the entry site and areas predisposed to hernia formation, observing aseptic technique and meticulous attention to early signs of complications during follow-up are vital to improve success rates. The outcomes of the laparoscopic single-port insertion technique shows promise compared with conventional Tenckhoff catheter insertion techniques.
