BACKGROUND
Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiological gastrostomy (PRG) are invasive interventions used for enteral access. We performed a systematic review and meta-analysis with assessment of certainty of evidence to compare the risk of adverse outcomes and technical failure between PEG and PRG.
METHODS
We queried PubMed, EMBASE, and Cochrane from inception through January 2022 to identify studies comparing outcomes of PEG and PRG. The primary outcome was 30-day all-cause mortality; secondary outcomes included the risk of colon perforation, peritonitis, bleeding, technical failure, peristomal infections, and tube-related complications. We performed GRADE assessment to assess the certainty of evidence and leave-one-out analysis for sensitivity analysis.
RESULTS
In the final analysis, 33 studies, including 26 high-quality studies, provided data on 275,117 patients undergoing PEG and 192,691 patients undergoing PRG. Data from high quality studies demonstrated that, compared to PRG, PEG had significantly lower odds of selected outcomes, including 30-day all-cause mortality (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.60-0.95; P=0.02), colon perforation (OR 0.61, 95%CI 0.49-0.75; P<0.001), and peritonitis (OR 0.71, 95%CI 0.63-0.81; P<0.001). There was no significant difference between PEG and PRG in terms of technical failure, bleeding, peristomal infections or mechanical complications. The certainty of the evidence was rated moderate for colon perforation and low for all other outcomes.
CONCLUSIONS
PEG is associated with a significantly lower risk of 30-day all-cause mortality, colon perforation, and peritonitis compared to PRG, while having a comparable technical failure rate. PEG should be considered as the first-line technique for enteral access.

BACKGROUND
Spontaneous bacterial peritonitis (SBP) is a common bacterial infection in cirrhotic patients associated with a high mortality rate. Prompt diagnosis and early antibiotic administration are crucial in minimizing adverse outcomes. Although detection of ≥250 polymorphonuclear leukocytes (PMN) in ascitic fluid is the current gold standard to diagnose SBP, consideration for rapid detection with biomarkers is warranted.
METHODS
A literature search for studies evaluating ascitic calprotectin and lactoferrin for detection of SBP was performed using PubMed, Embase, Scopus, Google Scholar, Cochrane library, and Clinical Trial Registries. Summary sensitivity, specificity, log diagnostic odds ratio (LDOR), and area under the summary receiver operating curve (AUC) were calculated.
RESULTS
In total, 12 and 13 studies evaluated ascitic calprotectin and lactoferrin, respectively, for detection of SBP. Summary sensitivity, specificity, and LDOR for calprotectin were 0.942 (95% CI, 0.916, 0.967), 0.860 (95% CI, 0.799, 0.935), and 4.250 (95% CI, 3.504, 4.990), respectively. AUC for calprotectin was 0.91. Summary sensitivity, specificity, and LDOR for lactoferrin were 0.954 (95% CI, 0.930, 0.979), 0.890 (95% CI, 0.836, 0.945), and 4.630 (95% CI, 3.800, 5.452), respectively. AUC for lactoferrin was 0.958.
CONCLUSIONS
The overall performance of ascitic calprotectin and lactoferrin was substantial, potentially serving as a screening tool or an alternative to manual cell count. However, a variety of manufacturers, cut-off values, and significant heterogeneity between studies should be noted. Point-of-care testing for calprotectin and lactoferrin may resolve disadvantages associated with the current methods. Future studies on this topic are, therefore, needed.

Meta-Analysis Review
BACKGROUND
The goal of this systematic review and meta-analysis was analyzing published studies on the role of neutrophil to lymphocyte ratio (NLR) in infection and spatially spontaneous bacterial peritonitis (SBP) among cirrhotic patients.
METHODS
PubMed, Web of Science, and Scopus were searched until May 24, 2022. The Newcastle-Ottawa scale was used for quality assessment.
RESULTS
Of 14 studies included in our study, six studies were on infection with 2786 hospitalized cirrhotic patients, of whom 934 developed an infection. Other studies were on SBP with 1573 cirrhotic patients with ascites, of whom 557 developed SBP. The pooled results showed that there was no difference in NLR levels between hospitalized cirrhotic patients who developed infection compared to those who did not (random-effects model: SMD = 0.63, 95% CI = -0.01-1.27, =0.054). However, cirrhotic patients with ascites who developed SBP had elevated levels of NLR compared to those who did not (random-effects model: SMD = 1.05, 95% CI = 0.52-1.57, < 0.001). This difference remained significant in prospective studies (SMD = 0.94, 95% CI = 0.51-1.38, < 0.001) but not in retrospective studies (SMD = 1.37, 95% CI = -0.56-3.29,=0.165), in the subgroup analysis according to the study design. The pooled sensitivity of NLR was 92.07% (95% CI = 74.85%-97.84%) and the pooled specificity was 72.58% (95% CI = 57.72%-83.69%). The pooled positive likelihood ratio, negative likelihood ratio, DOR of NLR were 3.35(95%CI = 2.06-5.46), 0.10 (95%CI = 0.03-0.38), and 30.78 (95%CI = 7.01-135.04), respectively.
CONCLUSION
Our results support NLR to be a valid biomarker that can be readily integrated into clinical settings to help in the prevention and prediction of SBP among cirrhotic patients.

BACKGROUND
Peritoneal dialysis (PD) is a major renal replacement therapy modality for patients with end-stage kidney disease (ESKD) worldwide. As poor self-care of PD patients could lead to serious complications, including peritonitis, exit-site infection, technique failure, and death; several nurse-based educational interventions have been introduced. However, these interventions varied and have been supported by small-scale studies so the effectiveness of nurse-based educational interventions on clinical outcomes of PD patients has been inconclusive.
OBJECTIVES
To evaluate the effectiveness of nurse-based education interventions in PD patients.
DESIGN
A systematic review and meta-analysis of Randomized Controlled Trials (RCTs).
METHODS
We performed a systematic search using PubMed, Embase, and CENTRAL up to December 31, 2021. Selection criteria included Randomized Controlled Trials (RCTs) relevant to nurse-based education interventions in ESKD patients with PD in the English language. The meta-analyses were conducted using a random-effects model to evaluate the summary outcomes of peritonitis, PD-related infection, mortality, transfer to hemodialysis, and quality of life (QoL).
RESULTS
From 9,816 potential studies, 71 theme-related abstracts were selected for further full-text articles screening against eligibility criteria. As a result, eleven studies (1,506 PD patients in seven countries) were included in our systematic review. Of eleven studies, eight studies (1,363 PD patients in five countries) were included in the meta-analysis. Sleep QoL in the intervention group was statistically significantly higher than control (mean difference = 12.76, 95% confidence intervals 5.26-20.27). There was no difference between intervention and control groups on peritonitis, PD-related infection, HD transfer, and overall QoL.
CONCLUSIONS
Nurse-based educational interventions could help reduce some PD complications, of which only the sleep QoL showed statistically significant improvement. High-quality evidence on the nurse-based educational interventions was limited and more RCTs are needed to provide more robust outcomes.
TWEETABLE ABSTRACT
Nurse-based educational interventions showed promising sleep quality improvement and potential peritonitis risk reduction among PD patients.

BACKGROUND
Gastrointestinal (GI) health is considered vital to the success of peritoneal dialysis (PD) and is critically important to patients, caregivers and clinicians. However, the multiplicity of GI outcome measures in trials undermines the ability to evaluate the frequency, impact and treatment of GI symptoms in patients receiving PD. Therefore, this study aimed to assess the range and consistency of GI outcomes reported in contemporary PD trials.
STUDY DESIGN
Systematic review.
SETTING AND POPULATION
Individuals with kidney failure requiring PD.
SELECTION CRITERIA
All randomised controlled trials involving patients on PD, identified from the PUBMED, EMBASE and COCHRANE Central Registry of controlled Trials (CENTRAL) database, from January 2010 to July 2022.
INTERVENTIONS
Any PD-related intervention.
OUTCOMES
The frequency and characteristics of GI outcome measures were analysed and classified.
RESULTS
Of the 324 eligible PD trials, GI outcomes were only reported in 61 (19%) trials, mostly as patient-reported outcomes (45 trials; 74%). The most frequently reported outcomes were in 27 (43%), in 26 (43%), in 22 (36%), in 21 (34%) and in 19 (31%) of trials. was the primary non-GI outcome reported in 24 (40%) trials, followed by in 13 (21%) trials) and exit-site infection in 9 (15%) trials). Across all trials, 172 GI outcome measures were extracted and grouped into 29 different outcomes. Nausea and diarrhoea contributed to 16% and 15% of GI outcomes, respectively, while vomiting, constipation and abdominal pain contributed to 13%, 12% and 12%, respectively. Most (90%) GI outcomes were patient-reported adverse effects with no defined metrics. was reported as the primary study outcome in 3 (100%) trials using the subjective global assessment score, GI symptom rating scale and faecal microbiological and biochemical analysis. Two trials reported nausea as a primary study outcome using One trial each reported as the primary study outcome using . were also reported as the primary study outcome in one trial each using the was reported as the secondary outcome in three (37%) out of eight trials reporting it.
LIMITATIONS
Restricted sampling frame to focus on contemporary trials.
CONCLUSIONS
Despite the clinical importance of GI outcomes among patients on PD, they are reported in only 19% of PD trials, using inconsistent metrics, often as patient-reported adverse events. Efforts to standardise GI outcome reporting are critical to optimising comparability, reliability and value of trial evidence to improve outcomes for patients receiving PD.

Meta-Analysis
BACKGROUND
Human albumin infusion is effective for controlling systemic inflammation, thereby probably managing some liver cirrhosis-related complications, such as spontaneous bacterial peritonitis (SBP), hepatic encephalopathy (HE), and hepatorenal syndrome. However, its clinical benefits remain controversial.
METHODS
EMBASE, PubMed, and Cochrane Library databases were searched. Randomized controlled trials (RCTs) regarding use of human albumin infusion in cirrhotic patients were eligible. Mortality and incidence of liver cirrhosis-related complications were pooled. Effect of human albumin infusion on mortality was also evaluated by subgroup analyses primarily according to target population and duration of human albumin infusion treatment. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.
RESULTS
Forty-two RCTs were finally included. Meta-analysis showed that human albumin infusion could significantly decrease the mortality of cirrhotic patients (OR = 0.81, 95% CI = 0.67-0.98, p = 0.03). Subgroup analyses showed that human albumin infusion could significantly decrease the mortality of cirrhotic patients with SBP (OR = 0.36, 95% CI = 0.20-0.64, p = 0.0005) and HE (OR = 0.43, 95% CI = 0.22-0.85, p = 0.02), but not those with ascites or non-SBP infections or undergoing large-volume paracentesis. Short-term human albumin infusion treatment could significantly decrease short-term mortality (OR = 0.67, 95% CI = 0.50-0.89, p = 0.005), but not long-term mortality. Long-term human albumin infusion treatment could not significantly decrease long-term mortality (OR = 0.72, 95% CI = 0.48-1.08, p = 0.11). In addition, human albumin infusion could significantly decrease the incidence of renal impairment (OR = 0.63, 95% CI = 0.45-0.88, p = 0.007) and ascites (OR = 0.45, 95% CI = 0.25-0.81, p = 0.007), but not infections or gastrointestinal bleeding.
CONCLUSIONS
Human albumin infusion may improve the outcomes of cirrhotic patients. However, its indications for different complications and infusion strategy in liver cirrhosis should be further explored.

BACKGROUND
Telehealth could potentially increase independency and autonomy of patients treated with peritoneal dialysis (PD). Moreover, it might improve clinical and economic outcomes. The demand for telehealth modalities accelerated significantly in the recent COVID-19 pandemic. We evaluated current literature on the impact of telehealth interventions added to PD-care on quality of life (QoL), clinical outcomes and cost-effectiveness.
METHODS
An electronic search was performed in Embase, PubMed and the Cochrane Library in order to find studies investigating associations between telehealth interventions and: i. QoL, including patient satisfaction; ii. Standardized Outcomes in Nephrology (SONG)-PD clinical outcomes: PD-related infections, mortality, cardiovascular disease and transfer to hemodialysis (HD); iii. Cost-effectiveness. Studies investigating hospitalizations and healthcare resource utilization were also included as secondary outcomes. Due to the heterogeneity of studies, a meta-analysis could not be performed.
RESULTS
Sixteen reports (N = 10,373) were included. Studies varied in terms of: sample size; design; risk of bias, telehealth-intervention and duration; follow-up time; outcomes and assessment tools. Remote patient monitoring (RPM) was the most frequently studied intervention (11 reports; N = 4982). Telehealth interventions added to PD-care, and RPM in particular, might reduce transfer to HD, hospitalization rate and length, as well as the number of in-person visits. It may also improve patient satisfaction.
CONCLUSION
There is a need for adequately powered prospective studies to determine which telehealth-modalities might confer clinical and economic benefit to the PD-community.

BACKGROUND
Spontaneous bacterial empyema (SBE) occurs when a hepatic hydrothorax becomes infected and runs a course similar to spontaneous bacterial peritonitis (SBP). It remains underdiagnosed as patients with cirrhosis do not routinely undergo diagnostic thoracentesis. Current understanding is limited by small cohorts, while studies reporting its association with ascites/SBP are conflicting.
AIM
To explore the incidence of SBE, to determine its association with ascites, and to summarize what is known regarding treatment and outcomes for patients with SBE.
METHODS
Major databases were searched until June 2021. Outcomes include the incidence of SBE in pleural effusions, SBP in peritoneal fluid, and SBE in patients without ascites within our cohort of patients with cirrhosis. We performed a meta-analysis using a random-effects model with pooled proportions and 95% confidence intervals (CI). We assessed heterogeneity using and classic fail-safe to determine bias.
RESULTS
Eight studies with 8899 cirrhosis patients were included. The median age ranged between 41.2 to 69.7 years. The majority of the patients were Child-Pugh B and C. Mean MELD score was 18.6 ± 8.09. A total of 1334 patients had pleural effusions and the pooled incidence of SBE was 15.6% (CI 12.6-19; 50). Amongst patients diagnosed with SBE, the most common locations included right (202), left (64), and bilateral (8). Amongst our cohort, a total of 2636 patients had ascites with a pooled incidence of SBP of 22.2% (CI 9.9-42.7; 97.8). The pooled incidence of SBE in patients with cirrhosis but without concomitant ascites was 9.5% (CI 3.6-22.8; 82.5).
CONCLUSION
SBE frequently occurs with concurrent ascites/SBP; our results suggest high incidence rates of SBE even in the absence of ascites. The pleura can be an unrecognized nidus and our findings support the use of diagnostic thoracentesis in patients with decompensated cirrhosis after exclusion of other causes of pleural effusion. Thoracentesis should be considered particularly in patients without ascites and when there is a high suspicion of infection. The need for diagnostic thoracentesis will continue to be important as rates of multi-drug resistant bacterial infections increase and antibiotic susceptibility information is required for adequate treatment.

Are salvage techniques safe and effective in the treatment of peritoneal dialysis catheter-related exit-site and tunnel infections? A systematic review and description of the authors' preferred technique.
BACKGROUND
Peritoneal dialysis catheter (PDC)-related infections account for significant morbidity, PD disruptions and costs. Patients with refractory exit-site or tunnel track infections without peritonitis may need catheter removal and reinsertion which can be complicated by bleeding, organ injury, catheter failure or malposition. Some patients may need to switch to haemodialysis in such a setting. An alternative is a salvage procedure. The purpose of this systematic review is to evaluate the safety and efficacy of salvage techniques.
METHODS
A comprehensive search of PubMed, Medline and Scopus databases was performed from inception to December 2021 in accordance with PRISMA guidelines. After a broad search, articles were stratified into two main categories for assessment: (1) cuff-shaving (CS) techniques and its variations of en-bloc resection (BR) and/or catheter diversion (CD) and (2) partial reimplantation with CD.
RESULTS
A total of 409 patients (445 salvage procedures) from 20 studies were included in analysis. Of 409 patients, 234 patients (57.2%) underwent 251 (56.4%) CS procedures and its variations, 163 patients (39.9%) underwent 182 (40.9%) partial PDC reimplantations with CD and 12 patients (2.7%) underwent local curettage. Overall PDC salvage rate after intervention was 73.2%. Overall PDC removal rate attributable to infection was 26.8%. Overall complication rate attributable to the procedures was 2.7%, with the most common complication being dialysate leakage ( = 10) followed by PDC laceration ( = 1) and subcutaneous haematoma ( = 1). We also included a description of our technique of BR of infected tissue, CS and CD. In a series of six patients, the PDC salvage rate was 83.3% and median PDC survival after intervention was 10 months.
CONCLUSION
PDC salvage techniques are relatively safe and provide reasonable catheter salvage rates in selected patients. Results of this review should lend weight to consideration of a salvage-first approach as an option in selected patients.

Meta-Analysis Review
PURPOSE
An increasing number of patients treated with peritoneal dialysis eventually undergo kidney transplantation. Owing to opposing reports, we aimed to find evidence about the best time for peritoneal dialysis catheter removal in transplant patients.
METHODS
We conducted a systematic review and random effects meta-analysis of non-randomized studies of intervention comparing patients with peritoneal dialysis catheters left in place or removed during kidney transplantation in regard to the need for dialysis and occurrence of catheter-related complications. We searched (last update on 8 December 2021) PubMed, Embase, Scopus, and Web of Science for eligible studies. ROBINS-I tool and funnel plot asymmetry analysis were used to assess the quality of included articles.
RESULTS
Eight observational studies were evaluated. Five of them, which involved 338 patients, were included in a meta-analysis. All were at moderate to serious risk of bias. The odds of needing dialysis are more than twice as high for patients with peritoneal dialysis catheters left in situ (pooled odds ratio, 2.21; 95% confidence interval [CI], 1.03 to 4.73; I = 0%). No statistically significant difference was noted when adult and pediatric subgroups were compared (Q = 0.13, P = .720). More individuals with catheters left in place required dialysis (pooled prevalence, 20.9%; 95% CI, 13.6 to 30.7%; I = 59% vs. 12.4%; 95% CI, 5.6 to 25.2%; I = 0%) and experienced catheter-related infections.
CONCLUSION
Available evidence is scarce. Unless new data from a randomized controlled trial are available, the dilemma of peritoneal dialysis catheter removal cannot be solved.
