Review
BACKGROUND
Hemodynamic instability related to renal replacement therapy (HIRRT) may increase the risk of death and limit renal recovery. Studies in end-stage renal disease populations on maintenance hemodialysis suggest that some renal replacement therapy (RRT)-related interventions (e.g., cool dialysate) may reduce the occurrence of HIRRT, but less is known about interventions to prevent HIRRT in critically ill patients receiving RRT for acute kidney injury (AKI). We sought to evaluate the effectiveness of RRT-related interventions for reducing HIRRT in such patients across RRT modalities.
METHODS
A systematic review of publications was undertaken using MEDLINE, MEDLINE in Process, EMBASE, and Cochrane's Central Registry for Randomized Controlled Trials (RCTs). Studies that assessed any intervention's effect on HIRRT (the primary outcome) in critically ill patients with AKI were included. HIRRT was variably defined according to each study's definition. Two reviewers independently screened abstracts, identified articles for inclusion, extracted data, and evaluated study quality using validated assessment tools.
RESULTS
Five RCTs and four observational studies were included (n = 9; 623 patients in total). Studies were small, and the quality was mostly low. Interventions included dialysate sodium modeling (n = 3), ultrafiltration profiling (n = 2), blood volume (n = 2) and temperature control (n = 3), duration of RRT (n = 1), and slow blood flow rate at initiation (n = 1). Some studies applied more than one strategy simultaneously (n = 5). Interventions shown to reduce HIRRT from three studies (two RCTs and one observational study) included higher dialysate sodium concentration, lower dialysate temperature, variable ultrafiltration rates, or a combination of strategies. Interventions not found to have an effect included blood volume and temperature control, extended duration of intermittent RRT, and slower blood flow rates during continuous RRT initiation. How HIRRT was defined and its frequency of occurrence varied widely across studies, including those involving the same RRT modality. Pooled analysis was not possible due to study heterogeneity.
CONCLUSIONS
Small clinical studies suggest that higher dialysate sodium, lower temperature, individualized ultrafiltration rates, or a combination of these strategies may reduce the risk of HIRRT. Overall, for all RRT modalities, there is a paucity of high-quality data regarding interventions to reduce the occurrence of HIRRT in critically ill patients.

Review
BACKGROUND
Postoperative intra-abdominal adhesions after GI surgery constitute a major burden for health care provision globally, causing chronic abdominal symptoms and necessitating repeated surgical intervention.
OBJECTIVE
This systematic review examines safety and efficacy data for current anti-adhesion strategies after GI surgery.
DATA SOURCES
PubMed, Medline, and Embase databases were searched for randomized control trials and nonrandomized clinical studies of anti-adhesion products from January 1980 to October 2013.
STUDY SELECTION
A list of predefined search terms was combined with the Cochrane Highly Sensitive Search Strategy to identify studies.
INTERVENTION
The use of an anti-adhesion strategy was investigated.
MAIN OUTCOME MEASURES
The primary outcome was the safety profile of anti-adhesion products. Secondary outcomes included the analysis of the reduction in the incidence, extent, and severity of adhesions; incidence of bowel obstruction; quality-of-life data; and oncological outcomes.
RESULTS
In total, 24 articles were included in the qualitative analysis: 17 randomized controlled trials and 7 nonrandomized studies, reporting on 5 anti-adhesion products. Data suggest that anti-adhesive products may be used safely; however, hyaluronic acid-based products should not be placed in contact with an anastomosis. The most studied product, a hyaluronic acid/carboxymethylcellulose membrane, reduces the incidence, extent, and severity of adhesions but without strong evidence of prevention of bowel obstruction.
LIMITATIONS
The size and quality of available studies varied greatly, reflected by the Jadad and MINORS scores. The majority of studies reported the use of a single product, hyaluronic acid/carboxymethylcellulose membrane.
CONCLUSIONS
Limiting adhesion formation after GI surgery is feasible. More evidence is needed regarding the efficacy in reducing chronic abdominal symptoms, repeated operative intervention, and improving quality of life.

Review
BACKGROUND
It is the object of debate whether a low or high dialysate sodium concentration (DNa(+)) should be advocated in chronic haemodialysis patients. In this paper, we aimed at evaluating benefits and harms of different DNa(+) prescriptions through a systematic review of the available literature.
METHODS
MEDLINE and CENTRAL databases were searched for studies comparing low or high DNa(+) prescriptions. Outcomes of interest were mortality, blood pressure (BP), interdialytic weight gain (IDWG), plasma sodium, hospitalizations, use of anti-hypertensive agents and intradialytic complications.
RESULTS
Twenty-three studies (76 635 subjects) were reviewed. There was high heterogeneity in the number of patients analysed, overall study quality, duration of follow-up, DNa(+) and even in the definition of 'high' or 'low' DNa(+). The only three studies looking at mortality were observational. The risk of death was related to the plasma-DNa(+) gradient, but was also shown to be confounded by indication from the dialysate sodium prescription itself. BP was not markedly affected by high or low DNa(+). Patients treated with higher DNa(+) had overall higher IDWG when compared with those with lower DNa(+). Three studies reported a significant increase in intra-dialytic hypotensive episodes in patients receiving low DNa(+). Data on hospitalizations and use of anti-hypertensive agents were sparse and inconclusive.
CONCLUSIONS
There is currently no definite evidence proving the superiority of a low or high uniform DNa(+) on hard or surrogate endpoints in maintenance haemodialysis patients. Future trials adequately powered to evaluate the impact of different DNa(+) on mortality or other patient-centred outcomes are needed.

Review
Since the early 1980s, multiple researchers have contributed to the development of models of the human gastrointestinal system for the mechanistic interrogation of the gut microbiome ecology. Using a bioreactor for simulating all the features and conditions of the gastrointestinal system is a massive challenge. Some conditions, such as temperature and pH, are readily controlled, but a more challenging feature to simulate is that both may vary in different regions of the gastrointestinal tract. Promising solutions have been developed for simulating other functionalities, such as dialysis capabilities, peristaltic movements, and biofilm growth. This research field is under constant development, and further efforts are needed to drive these models closer to conditions, thereby increasing their usefulness for studying the gut microbiome impact on human health. Therefore, understanding the influence of key operational parameters is fundamental for the refinement of the current bioreactors and for guiding the development of more complex models. In this review, we performed a systematic search for operational parameters in 229 papers that used continuous bioreactors seeded with human feces. Despite the reporting of operational parameters for the various bioreactor models being variable, as a result of a lack of standardization, the impact of specific operational parameters on gut microbial ecology is discussed, highlighting the advantages and limitations of the current bioreactor systems.

Anticoagulant therapies versus heparin for the prevention of hemodialysis catheter-related complications: systematic review and meta-analysis of prospective randomized controlled trials.
Locking of central venous catheters with heparin is an accepted practice to maintain catheter patency between dialysis sessions. However, this practice may cause other adverse reactions. Although many studies suggest benefits of other catheter lock solutions over heparin on these grounds, no consensus has been reached for clinical practice. A systematic review and meta-analysis was performed of randomized controlled trials (RCT) that compared antimicrobial-containing or citrate-alone catheter lock solutions with heparin alone in patients undergoing hemodialysis with central venous catheters. Medline, Cochrane Central Register of Controlled Trials from EMBASE, and PubMed were searched for articles published through June 2014. The primary outcomes were catheter-related bacteremia (CRB) and catheter malfunction (CM). The secondary outcomes were bleeding, exit-site infection (ESI), clinical sepsis, and all-cause mortality. Seventeen RCTs met the inclusion criteria. The meta-analysis showed that antimicrobial-containing and citrate-alone lock solutions were superior to heparin for preventing CRB (both P < 0.01). Although antimicrobial-containing lock solutions significantly affected clinical sepsis (P < 0.01), they did not affect ESI, bleeding, or all-cause mortality. Incidence of CM episodes was lower in patients receiving antibiotics + heparin and gentamicin + citrate (both P < 0.05), while other antimicrobial-containing and citrate-alone lock solutions showed no difference. Only citrate-alone lock solutions significantly decreased bleeding and ESI episodes (both P < 0.05). Compared with heparin, antimicrobial-containing lock solutions more effectively prevent CRB and clinical sepsis. Antibiotics + heparin and gentamicin + citrate solutions showing better prevention of CM. Citrate-alone lock solutions result in fewer CRB, bleeding and ESI episodes.

BACKGROUND AND OBJECTIVES
Hemodialysis catheters are commonly used when renal replacement therapy is initiated. These catheters have significant complications. Among "locking" solutions used in an attempt to decrease these complications is recombinant tissue plasminogen activator (rt-PA). This systematic review is to determine the efficacy of rt-PA versus heparin, the standard of care.
MATERIALS AND METHODS
A systematic review of randomized controlled trials studying rt-PA alone or rt-PA plus heparin versus heparin alone as locking agents for hemodialysis catheters, which included patients needed a temporary hemodialysis catheter for hemodialysis. We identified relevant trials through electronic databases and correspondence with experts. Two investigators independently reviewed potentially eligible trials and extracted data.
RESULTS
Three trials met the inclusion criteria. One trial reported an improved catheter malfunctioning in patients using rt-PA plus heparin to lock catheters (20.0%) versus heparin alone (34.8%). Another trial reported higher blood flow rate in hemodialysis catheters in patients who received rt-PA (231.6 ± 12.4 mL/min) compared with those who received heparin (206.9 mL/min). The third trial reported formation and weight of clots which were decreased by half in rt-PA group versus heparin group.
CONCLUSIONS
In the few randomized trials that met our inclusion criteria, the use of rt-PA as a locking solution for hemodialysis catheters seems to be associated with fewer adverse events and catheter malfunctioning as compared with heparin. Our systematic review is limited by the few randomized trials addressing our question and the wide variety of outcome measures. Further prospective randomized trials are needed to confirm this conclusion.

Meta-Analysis Review
BACKGROUND
Catheter malfunction, including thrombosis, is associated with reduced dialysis adequacy, as well as an increased risk of catheter-related bacteraemia and mortality. The role of anticoagulants in the prevention of catheter malfunction remains uncertain.
OBJECTIVES
This review aimed to compare the prophylactic effect of different anticoagulant agents, preparations, doses and administration on the incidence of central venous haemodialysis catheter-related malfunction and sepsis in patients with end-stage kidney disease (ESKD).
SEARCH METHODS
We searched the Cochrane Renal Group's Specialised Register to 7 January 2016 through contact with the Trials' Search Co-ordinator using search terms relevant to this review.
SELECTION CRITERIA
We included all randomised controlled trials (RCT) assessing anticoagulants compared with conventional care for the prevention of catheter malfunction in adult patients receiving haemodialysis for ESKD.
DATA COLLECTION AND ANALYSIS
The primary outcome was catheter malfunction defined as a catheter blood flow of 200 mL/min or less, or as defined by study authors. Secondary outcomes were catheter-related bacteraemia, all-cause mortality and bleeding events. Relative risks (RR) with 95% confidence intervals (CI) for individual studies were pooled using random effects models within treatment classes. Analyses were conducted by class, with subgroup analyses performed of individual agents within classes.
MAIN RESULTS
We included 27 studies (3003 participants) that were followed up for a median of six months. Study interventions included alternative anticoagulant locking solutions (19 studies, 2216 patients), systemic agents (6 studies, 664 patients) and low or no dose heparin (2 studies, 123 patients). The most common comparison treatment was a locking solution of heparin 5000 IU/mL, used in 17 studies. No significant effect on catheter malfunction was observed for alternative anticoagulant locking solutions (RR 0.96, 95% CI 0.74 to 1.26), systemic agents (RR 0.59, 95% CI 0.28 to 1.23), or low or no dose heparin (RR 0.90, 95% CI 0.10 to 8.31). A significant reduction on incidence of catheter-related bacteraemia was observed for alternative anticoagulant locking solutions (RR 0.46, 95% CI 0.32 to 0.66) but not systemic agents (RR 2.41, 95% CI 0.89 to 6.55), and could not be assessed in reports of low or no dose heparin studies. No significant effect on all-cause mortality was observed for alternative anticoagulant locking solutions (RR 0.88, 95% CI 0.54 to 1.43) or systemic agents (RR 0.78, 95% CI 0.37 to 1.65), and was not reported in studies of low or no dose heparin. Bleeding events were only reported in eight studies, including only 2/5 studies of systemic warfarin, with no clear effect demonstrated (RR 1.43, 95% CI 0.86 to 2.39). For individual agents, recombinant tissue plasminogen (rt-PA) was the only locking solution shown to reduce catheter malfunction (RR 0.58, 95% CI 0.37 to 0.91) based on the results of a single study. No significant on catheter malfunction was observed for other individual classes of alternative anticoagulant locking solutions (citrate: RR 1.14, 95% CI 0.76 to 1.69; antibiotic: RR 1.48, 95% CI 0.79 to 2.77; ethanol: RR 0.88, 95% CI 0.21 to 3.67). On the other hand, all individual classes of alternative anticoagulant locking solutions, except ethanol, reduced catheter-related bacteraemia (citrate: RR 0.49, 95% CI 0.36 to 0.68; antibiotic: RR 0.27, 95% CI 0.11 to 0.70; rt-PA: RR 0.35, 95% CI 0.13 to 0.93; ethanol: RR 0.33, 95% CI 0.03 to 4.05). No significant effect on all-cause mortality was observed for any individual agent within the class of alternative locking solutions. Studies were mainly of low quality and underpowered with an average participant number of 75 and study duration of six months. The interpretation of the study evidence was further limited by the variation in tested interventions and outcome reporting.
AUTHORS' CONCLUSIONS
The relative net benefit of anticoagulant therapies for prevention of catheter malfunction remains uncertain. Multiple agents appear to reduce catheter-related bacteraemia although the lack of clear assessment of harms and the limitations of study quality mean these results should be interpreted with caution. Methodological approaches can be used to avoid methods of reporting unduly affecting on the results of meta-analyses incorporating studies employed mixed reporting methods. Further high quality randomised studies, including safety outcomes, are needed.

Comparative Study Meta-Analysis
OBJECTIVE
To provide updated evidence, we conducted a systematic review and meta-analysis to compare citrate lock with heparin in the prevention of hemodialysis catheter-related complications.
METHODS
A systematic review and meta-analysis of randomized controlled trials were obtained by searching PubMed, EMBASE, Ovid, Cochrane library, and the Web of Science databases. Primary outcomes were catheter-related bloodstream infections (CRBI), exit-site infections, bleeding events, catheter removal for poor flow, and thrombolytic treatment. Secondary outcomes were thrombocytopenia, access-related admission, and all-cause mortality.
RESULTS
The meta-analysis showed that the citrate lock containing antimicrobials can reduce the risk of CRBI when compared with heparin lock (RR: 0.34, 95% CI 0.24-0.49; I = 0%; P < 0.00001), and a tunneled cuffed catheter (TCC) was more beneficial for the prevention of CRBI (RR: 0.42, 95% CI 0.25-0.69; I = 40%; P = 0.0007) when compared with non-tunneled cuffed catheters (NTCC). The microbiological correlation analysis suggests that the occurrence of CRBI is closely related to S. aureus in catheters locked by citrate (P = 0.015) rather than by heparin (P = 0.868). In the analysis of exit-site infection, citrate lock with NTCC was more effective in preventing exit-site infection than heparin (RR: 0.48, 95% CI 0.31-0.75; I = 0%; P = 0.001). In addition, the risk of bleeding episodes was reduced in hemodialysis patients using citrate lock with TCC (RR: 0.53, 95% CI 0.32-0.86; I = 0%; P = 0.01) and patients with citrate alone (RR: 0.51, 95% CI 0.30-0.85; I = 12%; P = 0.010). The risk of catheter removal for poor flow (P = 0.91), thrombolytic treatment (P = 0.76), thrombocytopenia (P = 0.37), access-related admission (P = 0.10), and all-cause mortality (P = 0.62) was not significantly different.
CONCLUSIONS
Antimicrobial-containing citrate lock solutions could reduce the risk of CRBI in hemodialysis patients. The occurrence of CRBI is closely related to S. aureus in catheters locked by citrate rather than by heparin. Citrate lock was effective in reducing exit-site infection in NTCC and bleeding events in TCC.

Meta-Analysis
BACKGROUND
Adhesions are fibrin bands that are a common consequence of gynaecological surgery. They are caused by conditions that include pelvic inflammatory disease and endometriosis. Adhesions are associated with comorbidities, including pelvic pain, subfertility, and small bowel obstruction. Adhesions also increase the likelihood of further surgery, causing distress and unnecessary expenses. Strategies to prevent adhesion formation include the use of fluid (also called hydroflotation) and gel agents, which aim to prevent healing tissues from touching one another, or drugs, aimed to change an aspect of the healing process, to make adhesions less likely to form.
OBJECTIVES
To evaluate the effectiveness and safety of fluid and pharmacological agents on rates of pain, live births, and adhesion prevention in women undergoing gynaecological surgery.
SEARCH METHODS
We searched: the Cochrane Gynaecology and Fertility Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and Epistemonikos to 22 August 2019. We also checked the reference lists of relevant papers and contacted experts in the field.
SELECTION CRITERIA
Randomised controlled trials investigating the use of fluid (including gel) and pharmacological agents to prevent adhesions after gynaecological surgery.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures recommended by Cochrane. We assessed the overall quality of the evidence using GRADE methods. Outcomes of interest were pelvic pain; live birth rates; incidence of, mean, and changes in adhesion scores at second look-laparoscopy (SLL); clinical pregnancy, miscarriage, and ectopic pregnancy rates; quality of life at SLL; and adverse events.
MAIN RESULTS
We included 32 trials (3492 women), and excluded 11. We were unable to include data from nine studies in the statistical analyses, but the findings of these studies were broadly in keeping with the findings of the meta-analyses. Hydroflotation agents versus no hydroflotation agents (10 RCTs) We are uncertain whether hydroflotation agents affected pelvic pain (odds ratio (OR) 1.05, 95% confidence interval (CI) 0.52 to 2.09; one study, 226 women; very low-quality evidence). It is unclear whether hydroflotation agents affected live birth rates (OR 0.67, 95% CI 0.29 to 1.58; two studies, 208 women; low-quality evidence) compared with no treatment. Hydroflotation agents reduced the incidence of adhesions at SLL when compared with no treatment (OR 0.34, 95% CI 0.22 to 0.55, four studies, 566 women; high-quality evidence). The evidence suggests that in women with an 84% chance of having adhesions at SLL with no treatment, using hydroflotation agents would result in 54% to 75% having adhesions. Hydroflotation agents probably made little or no difference to mean adhesion score at SLL (standardised mean difference (SMD) -0.06, 95% CI -0.20 to 0.09; four studies, 722 women; moderate-quality evidence). It is unclear whether hydroflotation agents affected clinical pregnancy rate (OR 0.64, 95% CI 0.36 to 1.14; three studies, 310 women; moderate-quality evidence) compared with no treatment. This suggests that in women with a 26% chance of clinical pregnancy with no treatment, using hydroflotation agents would result in a clinical pregnancy rate of 11% to 28%. No studies reported any adverse events attributable to the intervention. Gel agents versus no treatment (12 RCTs) No studies in this comparison reported pelvic pain or live birth rate. Gel agents reduced the incidence of adhesions at SLL compared with no treatment (OR 0.26, 95% CI 0.12 to 0.57; five studies, 147 women; high-quality evidence). This suggests that in women with an 84% chance of having adhesions at SLL with no treatment, the use of gel agents would result in 39% to 75% having adhesions. It is unclear whether gel agents affected mean adhesion scores at SLL (SMD -0.50, 95% CI -1.09 to 0.09; four studies, 159 women; moderate-quality evidence), or clinical pregnancy rate (OR 0.20, 95% CI 0.02 to 2.02; one study, 30 women; low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention. Gel agents versus hydroflotation agents when used as an instillant (3 RCTs) No studies in this comparison reported pelvic pain, live birth rate or clinical pregnancy rate. Gel agents probably reduce the incidence of adhesions at SLL when compared with hydroflotation agents (OR 0.50, 95% CI 0.31 to 0.83; three studies, 538 women; moderate-quality evidence). This suggests that in women with a 46% chance of having adhesions at SLL with a hydroflotation agent, the use of gel agents would result in 21% to 41% having adhesions. We are uncertain whether gel agents improved mean adhesion scores at SLL when compared with hydroflotation agents (MD -0.79, 95% CI -0.82 to -0.76; one study, 77 women; very low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention. Steroids (any route) versus no steroids (4 RCTs) No studies in this comparison reported pelvic pain, incidence of adhesions at SLL or mean adhesion score at SLL. It is unclear whether steroids affected live birth rates compared with no steroids (OR 0.65, 95% CI 0.26 to 1.62; two studies, 223 women; low-quality evidence), or clinical pregnancy rates (OR 1.01, 95% CI 0.66 to 1.55; three studies, 410 women; low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention.
AUTHORS' CONCLUSIONS
Gels and hydroflotation agents appear to be effective adhesion prevention agents for use during gynaecological surgery, but we found no evidence indicating that they improve fertility outcomes or pelvic pain, and further research is required in this area. It is also worth noting that for some comparisons, wide confidence intervals crossing the line of no effect meant that clinical harm as a result of interventions could not be excluded. Future studies should measure outcomes in a uniform manner, using the modified American Fertility Society score. Statistical findings should be reported in full. No studies reported any adverse events attributable to intervention.
