Meta-Analysis Review
Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) bacteremia can have poor clinical outcomes. Thus, determining the predictors of mortality from ESBL-PE bacteremia is very important. The present systematic review and meta-analysis aimed to evaluate studies to determine predictors associated with ESBL-PE bacteremia mortality. We searched PubMed and Cochrane Library databases for all relevant publications from January 2000 to August 2022. The outcome measure was mortality rate. In this systematic review of 22 observational studies, 4607 patients with ESBL-PE bacteremia were evaluated, of whom 976 (21.2%) died. The meta-analysis showed that prior antimicrobial therapy (RR, 2.89; 95% CI, 1.22-6.85), neutropenia (RR, 5.58; 95% CI, 2.03-15.35), nosocomial infection (RR, 2.46; 95% CI, 1.22-4.95), rapidly fatal underlying disease (RR, 4.21; 95% CI, 2.19-8.08), respiratory tract infection (RR, 2.12; 95% CI, 1.33-3.36), Pitt bacteremia score (PBS) (per1) (RR, 1.35; 95% CI, 1.18-1.53), PBS ≥ 4 (RR, 4.02; 95% CI, 2.77-5.85), severe sepsis (RR, 11.74; 95% CI, 4.68-29.43), and severe sepsis or septic shock (RR, 4.19; 95% CI, 2.83-6.18) were found to be mortality predictors. Moreover, urinary tract infection (RR, 0.15; 95% CI, 0.04-0.57) and appropriate empirical therapy (RR, 0.39; 95% CI, 0.18-0.82) were found to be a protective factor against mortality. Patients with ESBL-PE bacteremia who have the aforementioned require prudent management for improved outcomes. This research will lead to better management and improvement of clinical outcomes of patients with bacteremia caused by ESBL-PE.

Meta-Analysis Review
Vancomycin-resistant enterococci (VRE) cause many infections in the healthcare context. Knowledge regarding the epidemiology and burden of VRE infections, however, remains fragmented. We aimed to summarize recent studies on VRE epidemiology and outcomes in hospitals, long-term-care facilities (LTCFs) and nursing homes worldwide based on current epidemiological reports. We searched MEDLINE/PubMed, the Cochrane Library, and Web of Science for observational studies, which reported on VRE faecium and faecalis infections in in-patients published between January 2014 and December 2020. Outcomes were incidence, infection rate, mortality, length of stay (LOS), and healthcare costs. We conducted a meta-analysis on mortality (PROSPERO registration number: CRD42020146389). Of 681 identified publications, 57 studies were included in the analysis. Overall quality of evidence was moderate to low. VRE incidence was rarely and heterogeneously reported. VRE infection rate differed highly (1-55%). The meta-analysis showed a higher mortality for VRE faecium bloodstream infections (BSIs) compared with VSE faecium BSIs (risk ratio, RR 1.46; 95% confidence interval (CI) 1.17-1.82). No difference was observed when comparing VRE faecium vs VRE faecalis BSI (RR 1.00, 95% CI 0.52-1.93). LOS was higher in BSIs caused by E. faecium vs E. faecalis. Only three studies reported healthcare costs. In contrast to previous findings, our meta-analysis of included studies indicates that vancomycin resistance independent of VRE species may be associated with a higher mortality. We identified a lack of standardization in reporting outcomes, information regarding healthcare costs, and state-of-the-art microbiological species identification methodology, which may inform the set-up and reporting of future studies.

Review
OBJECTIVES
Epidemiological surveillance is one critical approach to estimate and fight the burden of antibiotic resistance (AR). Here we summarise the characteristics of surveillance systems devoted to the surveillance of AR worldwide and published in the literature.
METHODS
We performed a systematic review of the literature available on PubMed from January 2007 to July 2019 (12.5 years). The keywords ('surveillance system' OR 'laboratory-based surveillance' OR 'syndromic surveillance' OR 'sentinel surveillance' OR 'integrated surveillance' OR 'population-based surveillance') AND ('antibiotic resistance' OR 'antimicrobial resistance') were used. This research was completed with AR monitoring systems available on websites.
RESULTS
We identified 71 AR surveillance systems described by 90 publications from 35 countries, including 64 (90.1%) national and 7 (9.9%) multinational surveillance systems. Two regions accounted for ∼72% of systems: European region (37; 52.1%) and Region of the Americas (14; 19.7%). Fifty-three focused on AR surveillance in humans, 12 studied both humans and animals, and 6 focused only on animals. The two most common bacterial species reported were Staphylococcus aureus (42; 59.2%) and Escherichia coli (39; 54.9%). Of the 71 AR surveillance systems, 20 (28.2%) used prevalence as an indicator, 3 (4.2%) used incidence and 7 (9.9%) used both. Methicillin-resistant S. aureus (MRSA), vancomycin-resistant Enterococcus spp., S. aureus and Streptococcus pneumoniae, penicillin-resistant S. pneumoniae, and extended-spectrum β-lactamase (ESBL)-producing and carbapenem-resistant E. coli and Klebsiella pneumoniae were monitored.
CONCLUSIONS
Our results showed heterogeneous surveillance systems. A 'One Health' approach is needed to monitor AR, with reference to the WHO Global Action Plan.

Meta-Analysis
OBJECTIVES
To quantify the association between income and antibiotic misuse including unprescribed use, storage of antibiotics and non-adherence.
METHODS
We identified pertinent studies through database search, and manual examination of reference lists of selected articles and review reports. We performed a dose-response meta-analysis of income, both continuous and categorical, in relation to antibiotic misuse. Summary odds ratios (ORs) and their 95% confidence intervals (CIs) were estimated under a random-effects random effects model.
RESULTS
Fifty-seven studies from 22 countries of different economic class were included. Overall, the data are in agreement with a flat linear association between income standardized to socio-economic indicators and antibiotic misuse (OR per 1 unit increment = 1.00, p-value = 0.954, p-value non-linearity = 0.429). Data were compatible with no association between medium and high income with general antibiotic misuse (OR 1.04; 95% CI 0.89, 1.20 and OR 1.03; 95% CI 0.82, 1.29). Medium income was associated with 19% higher odds of antibiotic storage (OR 1.19; 95% CI 1.07, 1.32) and 18% higher odds of any aspect of antibiotic misuse in African studies (OR 1.18; 95% CI 1.00, 1.39). High income was associated with 51% lower odds of non-adherence to antibiotic treatment (OR 0.49; 95% CI 0.34, 0.60). High income was also associated with 11% higher odds of any antibiotic misuse in upper-middle wealth countries (OR 1.11; 95% CI 1.00, 1.22).
CONCLUSIONS
The association between income and antibiotic misuse varies by type of misuse and country wellness. Understanding the socioeconomic properties of antibiotic misuse should prove useful in developing related intervention programs and health policies.

Meta-Analysis
BACKGROUND
Antimicrobial resistance of bacterial pathogens is an increasing clinical problem and alternative approaches to antibiotic chemotherapy are needed. One of these approaches is the use of lytic bacterial viruses known as phage therapy. We aimed to assess the efficacy of phage therapy in preclinical animal models of bacterial infection.
METHODS
In this systematic review and meta-analysis, MEDLINE/Ovid, Embase/Ovid, CINAHL/EbscoHOST, Web of Science/Wiley, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar were searched from inception to Sept 30, 2021. Studies assessing phage efficacy in animal models were included. Only studies that assessed the efficacy of phage therapy in treating established bacterial infections in terms of survival and bacterial abundance or density were included. Studies reporting only in-vitro or ex-vivo results and those with incomplete information were excluded. Risk-of-bias assessment was performed using the Systematic Review Centre for Laboratory Animal Experimentation tool. The main endpoints were animal survival and tissue bacterial burden, which were reported using pooled odds ratios (ORs) and mean differences with random-effects models. The I measure and its 95% CI were also calculated. This study is registered with PROSPERO, CRD42022311309.
FINDINGS
Of the 5084 references screened, 124 studies fulfilled the selection criteria. Risk of bias was high for 70 (56%) of the 124 included studies; therefore, only studies classified as having a low-to-moderate risk of bias were considered for quantitative data synthesis (n=32). Phage therapy was associated with significantly improved survival at 24 h in systemic infection models (OR 0·08 [95% CI 0·03 to 0·20]; I=55% [95% CI 8 to 77]), skin infection (OR 0·08 [0·04 to 0·19]; I = 0% [0 to 79]), and pneumonia models (OR 0·13 [0·06 to 0·31]; I=0% [0 to 68]) when compared with placebo. Animals with skin infections (mean difference -2·66 [95% CI -3·17 to -2·16]; I = 95% [90 to 96]) and those with pneumonia (mean difference -3·35 [-6·00 to -0·69]; I = 99% [98 to 99]) treated with phage therapy had significantly lower tissue bacterial loads at 5 ± 2 days of follow-up compared with placebo.
INTERPRETATION
Phage therapy significantly improved animal survival and reduced organ bacterial loads compared with placebo in preclinical animal models. However, high heterogeneity was observed in some comparisons. More evidence is needed to identify the factors influencing phage therapy performance to improve future clinical application.

Meta-Analysis
BACKGROUND
Pleural infection, including parapneumonic effusions and thoracic empyema, may complicate lower respiratory tract infections. Standard treatment of these collections in adults involves antibiotic therapy, effective drainage of infected fluid and surgical intervention if conservative management fails. Intrapleural fibrinolytic agents such as streptokinase and alteplase have been hypothesised to improve fluid drainage in complicated parapneumonic effusions and empyema and therefore improve treatment outcomes and prevent the need for thoracic surgical intervention. Intrapleural fibrinolytic agents have been used in combination with DNase, but this is beyond the scope of this review.
OBJECTIVES
To assess the benefits and harms of adding intrapleural fibrinolytic therapy to standard conservative therapy (intercostal catheter drainage and antibiotic therapy) in the treatment of complicated parapneumonic effusions and empyema.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and Embase, ClinicalTrials.gov and the World Health Organization (WHO) trials portal. We contacted trial authors for further information and requested details regarding the possibility of unpublished trials. The most recent search was conducted on 28 August 2019.
SELECTION CRITERIA
Parallel-group randomised controlled trials (RCTs) in adult patients with post-pneumonic empyema or complicated parapneumonic effusions (excluding tuberculous effusions) who had not had prior surgical intervention or trauma comparing an intrapleural fibrinolytic agent (streptokinase, alteplase or urokinase) versus placebo or a comparison of two fibrinolytic agents.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data. We contacted study authors for further information. We used odds ratios (OR) for dichotomous data and reported 95% confidence intervals (CIs). We used Cochrane's standard methodological procedures of meta-analysis. We applied the GRADE approach to summarise results and to assess the overall certainty of evidence.
MAIN RESULTS
We included in this review a total of 12 RCTs. Ten studies assessed fibrinolytic agents versus placebo (993 participants); one study compared streptokinase with urokinase (50 participants); and one compared alteplase versus urokinase (99 participants). The primary outcomes were death, requirement for surgical intervention, overall treatment failure and serious adverse effects. All studies were in the inpatient setting. Outcomes were measured at varying time points from hospital discharge to three months. Seven trials were at low or unclear risk of bias and two at high risk of bias due to inadequate randomisation and inappropriate study design respectively. We found no evidence of difference in overall mortality with fibrinolytic versus placebo (OR 1.16, 95% CI 0.71 to 1.91; 8 studies, 867 participants; I² = 0%; moderate certainty of evidence). We found evidence of a reduction in surgical intervention with fibrinolysis in the same studies (OR 0.37, 95% CI 0.21 to 0.68; 8 studies, 897 participants; I² = 51%; low certainty of evidence); and overall treatment failure (OR 0.16, 95% CI 0.05 to 0.58; 7 studies, 769 participants; I² = 88%; very low certainty of evidence, with evidence of significant heterogeneity). We found no clear evidence of an increase in adverse effects with intrapleural fibrinolysis, although this cannot be excluded (OR 1.28, 95% CI 0.36 to 4.57; low certainty of evidence). In a sensitivity analysis, the reduction in referrals for surgery and overall treatment failure with fibrinolysis disappeared when the analysis was confined to studies at low or unclear risk of bias. In a moderate-risk population (baseline 14% risk of death, 20% risk of surgery, 27% risk of treatment failure), intra-pleural fibrinolysis leads to 19 more deaths (36 fewer to 59 more), 115 fewer surgical interventions (150 fewer to 55 fewer) and 214 fewer overall treatment failures (252 fewer to 93 fewer) per 1000 people. A single study of streptokinase versus urokinase found no clear difference between the treatments for requirement for surgery (OR 1.00, 95% CI 0.13 to 7.72; 50 participants; low-certainty evidence). A single study of alteplase versus urokinase showed no clear difference in requirement for surgery (OR alteplase versus urokinase 0.46, 95% CI 0.04 to 5.24) but an increased rate of adverse effects, primarily bleeding, with alteplase (OR 5.61, 95% CI 1.16 to 27.11; 99 participants; low-certainty evidence). This translated into 154 (6 to 499 more) serious adverse events with alteplase compared with urokinase per 1000 people treated.
AUTHORS' CONCLUSIONS
In patients with complicated infective pleural effusion or empyema, intrapleural fibrinolytic therapy was associated with a reduction in the requirement for surgical intervention and overall treatment failure but with no evidence of change in mortality. Discordance between the negative largest trial of this therapy and other studies is of concern, however, as is an absence of significant effect when analysing low risk of bias trials only. The reasons for this difference are uncertain but may include publication bias. Intrapleural fibrinolytics may increase the rate of serious adverse events, but the evidence is insufficient to confirm or exclude this possibility.

BACKGROUND
Trachoma is the world's leading infectious cause of blindness. In 1996, WHO launched the Alliance for the Global Elimination of Trachoma by the year 2020, based on the 'SAFE' strategy (surgery, antibiotics, facial cleanliness, and environmental improvement).
OBJECTIVES
To assess the evidence supporting the antibiotic arm of the SAFE strategy by assessing the effects of antibiotics on both active trachoma (primary objective), Chlamydia trachomatis infection of the conjunctiva, antibiotic resistance, and adverse effects (secondary objectives).
SEARCH METHODS
We searched relevant electronic databases and trials registers. The date of the last search was 4 January 2019.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that satisfied either of two criteria: (a) trials in which topical or oral administration of an antibiotic was compared to placebo or no treatment in people or communities with trachoma, (b) trials in which a topical antibiotic was compared with an oral antibiotic in people or communities with trachoma. We also included studies addressing different dosing strategies in the population. DATA COLLECTION AND ANALYSIS: We used standard methods expected by Cochrane. We assessed the certainty of the evidence using the GRADE approach.
MAIN RESULTS
We identified 14 studies where individuals with trachoma were randomised and 12 cluster-randomised studies. Any antibiotic versus control (individuals)Nine studies (1961 participants) randomised individuals with trachoma to antibiotic or control (no treatment or placebo). All of these studies enrolled children and young people with active trachoma. The antibiotics used in these studies included topical (oxy)tetracycline (5 studies), doxycycline (2 studies), and sulfonamides (4 studies). Four studies had more than two study arms. In general these studies were poorly reported, and it was difficult to judge risk of bias.These studies provided low-certainty evidence that people with active trachoma treated with antibiotics experienced a reduction in active trachoma at three months (risk ratio (RR) 0.78, 95% confidence interval (CI) 0.69 to 0.89; 1961 people; 9 RCTs; I = 73%) and 12 months (RR 0.74, 95% CI 0.55 to 1.00; 1035 people; 4 RCTs; I = 90%). Low-certainty evidence was available for ocular infection at three months (RR 0.81, 95% CI 0.63 to 1.04; 297 people; 4 RCTs; I = 0%) and 12 months (RR 0.25, 95% CI 0.08 to 0.78; 129 people; 1 RCT). None of these studies assessed antimicrobial resistance. In those studies that reported harms, no serious adverse effects were reported (low-certainty evidence).Oral versus topical antibiotics (individuals)Eight studies (1583 participants) compared oral and topical antibiotics. Only one study included people older than 21 years of age. Oral antibiotics included azithromycin (5 studies), sulfonamides (2 studies), and doxycycline (1 study). Topical antibiotics included (oxy)tetracycline (6 studies), azithromycin (1 study), and sulfonamide (1 study). These studies were poorly reported, and it was difficult to judge risk of bias.There was low-certainty evidence of little or no difference in effect between oral and topical antibiotics on active trachoma at three months (RR 0.97, 95% CI 0.81 to 1.16; 953 people; 6 RCTs; I = 63%) and 12 months (RR 0.93, 95% CI 0.75 to 1.15; 886 people; 5 RCTs; I = 56%). There was very low-certainty evidence for ocular infection at three or 12 months. Antimicrobial resistance was not assessed. In those studies that reported adverse effects, no serious adverse effects were reported; one study reported abdominal pain with azithromycin; one study reported a couple of cases of nausea with azithromycin; and one study reported three cases of reaction to sulfonamides (low-certainty evidence).Oral azithromycin versus control (communities)Four cluster-randomised studies compared antibiotic with no or delayed treatment. Data were available on active trachoma at 12 months from two studies but could not be pooled because of reporting differences. One study at low risk of bias found a reduced prevalence of active trachoma 12 months after a single dose of azithromycin in communities with a high prevalence of infection (RR 0.58, 95% CI 0.52 to 0.65; 1247 people). The other, lower quality, study in low-prevalence communities reported similar median prevalences of infection at 12 months: 9.3% in communities treated with azithromycin and 8.2% in untreated communities. We judged this moderate-certainty evidence for a reduction in active trachoma with treatment, downgrading one level for inconsistency between the two studies. Two studies reported ocular infection at 12 months and data could be pooled. There was a reduction in ocular infection (RR 0.36, 0.31 to 0.43; 2139 people) 12 months after mass treatment with a single dose compared with no treatment (moderate-certainty evidence). There was high-certainty evidence of an increased risk of resistance of Streptococcus pneumoniae, Staphylococcus aureus, and Escherichia coli to azithromycin, tetracycline, and clindamycin in communities treated with azithromycin, with approximately 5-fold risk ratios at 12 months. The evidence did not support increased resistance to penicillin or trimethoprim-sulfamethoxazole. None of the studies measured resistance to C trachomatis. No serious adverse events were reported. The main adverse effect noted for azithromycin (˜10%) was abdominal pain, vomiting, and nausea.Oral azithromycin versus topical tetracycline (communities)Three cluster-randomised studies compared oral azithromycin with topical tetracycline. The evidence was inconsistent for active trachoma and ocular infection at three and 12 months (low-certainty evidence) and was not pooled due to considerable heterogeneity. Antimicrobial resistance and adverse effects were not reported.Different dosing strategiesSix studies compared different strategies for dosing. There were: mass treatment at different dosing intervals; applying cessation or stopping rules to mass treatment; strategies to increase mass treatment coverage. There was no strong evidence to support any variation in the recommended annual mass treatment.
AUTHORS' CONCLUSIONS
Antibiotic treatment may reduce the risk of active trachoma and ocular infection in people infected with C trachomatis, compared to no treatment/placebo, but the size of the treatment effect in individuals is uncertain. Mass antibiotic treatment with single dose oral azithromycin reduces the prevalence of active trachoma and ocular infection in communities. There is no strong evidence to support any variation in the recommended periodicity of annual mass treatment. There is evidence of an increased risk of antibiotic resistance at 12 months in communities treated with antibiotics.

Meta-Analysis Review
Research has been conducted into the advantages of the systemic administration of antibiotics. The aim of this systematic review and meta-analysis was to assess the efficacy of systemic antibiotic administration in the treatment of peri-implantitis in terms of bleeding on probing (BoP) and probing pocket depth (PPD). Literature searches were performed across PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) to identify randomized controlled trials and observational clinical studies. After peri-implantitis treatment, PPD was reduced by 0.1 mm ( = 0.58; IC 95% [-0.24, 0.47]), indicating a non-significant effect of antibiotic administration on PPD. The BoP odds ratio value was 1.15 ( = 0.5; IC 95% [0.75, 1.75]), indicating that the likelihood of bleeding is almost similar between the test and control groups. Secondary outcomes were found, such as reduced clinical attachment level, lower suppuration and recession, less bone loss, and a reduction in total bacterial counts. In the treatment of peri-implantitis, the systemic antibiotic application reduces neither PPD nor BoP. Therefore, the systemic administration of antibiotics, in the case of peri-implantitis, should be rethought in light of the present results, contributing to address the problem of increasing antibiotic resistance.

Meta-Analysis
IMPORTANCE
Antimicrobial resistance continues to spread rapidly at a global scale. Little evidence exists on the association of antimicrobial stewardship programs (ASPs) with the consumption of antibiotics across health care and income settings.
OBJECTIVE
To synthesize current evidence regarding the association between antimicrobial stewardship programs and the consumption of antibiotics globally.
DATA SOURCES
PubMed, Web of Science, and Scopus databases were searched from August 1, 2010, to Aug 1, 2020. Additional studies from the bibliography sections of previous systematic reviews were included.
STUDY SELECTION
Original studies of the association of ASPs with antimicrobial consumption across health care and income settings. Animal and environmental studies were excluded.
DATA EXTRACTION AND SYNTHESIS
Following the Preferred Reporting Items in Systematic Reviews and Meta-Analyses guideline, the pooled association of targeted ASPs with antimicrobial consumption was measured using multilevel random-effects models. The Effective Public Health Practice Project quality assessment tool was used to assess study quality.
MAIN OUTCOMES AND MEASURES
The main outcome measures were proportion of patients receiving an antibiotic prescription and defined daily doses per 100 patient-days.
RESULTS
Overall, 52 studies (with 1 794 889 participants) measured the association between ASPs and antimicrobial consumption and were included, with 40 studies conducted in high-income countries and 12 in low- and middle-income countries (LMICs). ASPs were associated with a 10% (95% CI, 4%-15%) reduction in antibiotic prescriptions and a 28% reduction in antibiotic consumption (rate ratio, 0.72; 95% CI, 0.56-0.92). ASPs were also associated with a 21% (95% CI, 5%-36%) reduction in antibiotic consumption in pediatric hospitals and a 28% reduction in World Health Organization watch groups antibiotics (rate ratio, 0.72; 95% CI, 0.56-0.92).
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, ASPs appeared to be effective in reducing antibiotic consumption in both hospital and nonhospital settings. Impact assessment of ASPs in resource-limited settings remains scarce; further research is needed on how to best achieve reductions in antibiotic use in LMICs.
