Review
The spread of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae has become a major public health threat worldwide. Area covered: A thorough systematic literature review describing the current evidence and future prospects of therapeutic options for infections caused by ESBL-producing Enterobacteriaceae. Expert commentary: The methods of detecting ESBLs have been evolving. The Clinical and Laboratory Standards Institute and the European Committee on Antimicrobial Susceptibility Testing lowered the MIC breakpoints of cephalosporins against ESBL-producing Enterobacteriaceae in 2010. Phenotypic testing for ESBLs is no longer recommended. Instead, the selection of appropriate antimicrobial agents largely depends on the report of minimum inhibitory concentrations (MICs). To date, therapeutic options for these multidrug-resistant organisms remain limited. The clinical efficacy of piperacillin/tazobactam and cefepime on in vitro-susceptible ESBL-producing Enterobacteriaceae remains a concern. Many studies found an in vitro-in vivo discordance based on current breakpoints. Carbapenems are the most reliable antibiotics for severe infections caused by ESBL-producing Enterobacteriaceae. However, their overuse has led to a serious problem of increasing drug resistance. Recently, ceftolozane/tazobactam and ceftazidime/avibactam have been approved for the treatment of complicated urinary tract infections and complicated intra-abdominal infections. The introduction of these new β-lactam/β-lactamase inhibitor combinations offers new carbapenem-sparing options for the treatment of ESBL infections.

Review
Empiric therapy for hospital-acquired, Gram-negative complicated intra-abdominal infection and complicated urinary tract infections: a systematic literature review of current and emerging treatment options.
BACKGROUND
Empiric therapy for healthcare-associated infections remains challenging, especially with the continued development of Gram-negative organisms producing extended-spectrum β-lactamases (ESBLs) and the threat of multi-drug-resistant organisms. Current treatment options for resistant Gram-negative infections include carbapenems, tigecycline, piperacillin-tazobactam, cefepime, ceftazidime, and two recently approved therapies, ceftolozane-tazobactam and ceftazidime-avibactam.
METHODS
This systematic literature review surveys the published clinical trial evidence available since 2000 in support of both current and emerging treatment options in the settings of complicated intra-abdominal infection (cIAI) and complicated urinary tract infection (cUTI). When available, clinical cure rates for patients with infections from ESBL-producing strains are provided, as is information about efficacy against Pseudomonas aeruginosa.
RESULTS
Clinical trial evidence to guide selection of empiric antibiotic therapy in patients with complicated, hospital-acquired, Gram-negative IAIs and UTIs is limited. Though most of the clinical trials explored in this overview enrolled patients with complicated infections, often patients with severe infections and multiple comorbidities were excluded.
CONCLUSIONS
Practitioners in the clinical setting who are treating patients with complicated, hospital-acquired, Gram-negative IAIs and UTIs need to consider the possibility of polymicrobial infections, antibiotic-resistant organisms, and/or severely ill patients with multiple comorbidities. There is a severe shortage of evidence-based research to guide the selection of empiric antibiotic therapy for many patients in this setting. New therapies recently approved or in late-stage development promise to expand the number of options available for empiric therapy of these hospital-acquired, Gram-negative infections.

Meta-Analysis Review
It has been widely reported that the incidence and severity of Clostridium difficile infection (CDI) have increased dramatically in North America and Europe. However, little is known about CDI in Mainland China. In this study, we aimed to investigate the incidence of CDI and the main epidemic and drug-resistant strains of C. difficile in Mainland China through meta-analysis of related studies published after the year 2010. A total of 51 eligible studies were included. The pooled incidence of toxigenic C. difficile among patients with diarrhoea was 14% (95% CI = 12-16%). In Mainland China, ST-37 and ST-3 were the most prevalent strains; fortunately, hypervirulent strains, such as ST-1 (BI/NAP1/027) and ST-11 (RT 078), have only occurred sporadically to date. The rates of C. difficile resistance to ciprofloxacin (98.3%; 95% CI = 96.9-99.7%), clindamycin (81.7%; 95% CI = 76.1-87.3%) and erythromycin (80.2%; 95% CI = 73.5-86.9%) are higher than in other counties; however, none of the C. difficile isolates reported in Mainland China were resistant to metronidazole (n/N = 0/960), vancomycin (n/N = 0/960), tigecycline (n/N = 0/41) or piperacillin/tazobactam(n/N = 0/288).

BACKGROUND
infections have gradually emerged as life-threatening nosocomial infections worldwide, accompanied by increasing incidence, multidrug resistance and poor outcomes. However, the epidemiology and clinical features of infection are still limited in mainland China.
METHODS
Patients with infections from 2011 to 2019 in southwestern China were retrospectively analyzed. The clinical features, infection patterns and outcomes were extracted from medical records and analyzed. A comprehensive systematic review was performed in accordance with PRISMA guidelines from conception to August 23, 2021.
RESULTS
Ninety-two patients were ultimately included, with the prevalence rapidly rising from 0 in 2011 to 0.19 per 1000 inpatients in 2019. A total of 93.48% of isolates were multidrug resistant, including 100% resistance to carbapenem. Furthermore, 75% of infections were concomitant with other pathogens. The mortality of our cohort was 36.96%, with risk factors for mechanical ventilation (OR=9.51, P=0.004), male sex (OR=0.27, P=0.031) and more concomitant pathogens. After propensity score matching, central venous catheters, exposure to carbapenem and antifungal drugs, and underlying tumors were associated with infection. Sixteen articles were also summarized, with reported mortality rates ranging from 11.0% to 66.6%. Blood and respiratory tract were the common sources. Piperacillin/tazobactam, trimethoprim/sulfamethoxazole, fluoroquinolone and minocycline were the most sensitive antibiotics. Inappropriate antibiotic treatment was the most commonly reported risk factor for mortality.
CONCLUSION
Nosocomial infection with has become an emerging problem with high mortality in southwestern China. Inappropriate antibiotic treatment and central venous catheters are risk factors for infection and death and should receive adequate attention.

The aim of this systematic review was to assess AKI (acute kidney injury) in adult patients, treated with vancomycin (V) + piperacillin/tazobactam (PT) compared to V monotherapy. Studies were found in Pubmed, Web of Science and Scopus databases. Articles not in English, pediatric studies and case reports were excluded. A study is eligible for inclusion if the adjusted Odds ratio (aOR) for AKI in V + PT compared to V monotherapy groups, could be extracted or determined from available data. Six retrospective cohort studies were eligible for inclusion criteria and so they were included in the analysis. All studies separately showed a significant higher risk of developing AKI (OR > 1, p < 0.05) in V + PT group compared to V monotherapy group. Considering the methodological difference of included studies, a random effect model was preferred. The model showed a pooled significant higher risk of developing AKI [OR 2.77 (95% CI 1.94, 3.96), p < 0.0001] in V + PT group compared to V group. Association of V and PT appears to be associated with a greater risk of AKI compared to V in monotherapy. These results may serve as the impetus for further evaluation into true mechanisms behind this additive nephrotoxic effect and its potential implications on mortality.

Comparative Study Meta-Analysis
INTRODUCTION
Early empirical broad-spectrum antimicrobial therapy is recommended for patients with severe infections, including sepsis. β-lactam/β-lactamase inhibitor combinations or carbapenems are often used to ensure coverage of likely pathogens. Piperacillin/tazobactam is proposed as a carbapenem-sparing agent to reduce the incidence of multidrug-resistant bacteria and superinfections. In the recently published MERINO trial, increased mortality from piperacillin/tazobactam was suggested in patients with bacteraemia with resistant Escherichia coli or Klebsiella species. Whether these findings also apply to empirical piperacillin/tazobactam in patients with other severe infections, including sepsis, is unknown. We aim to assess the benefits and harms of empirical and definitive piperacillin/tazobactam vs carbapenems for patients with severe bacterial infections.
METHODS AND ANALYSIS
This protocol has been prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement, the Cochrane Handbook and the Grading of Recommendations, Assessment, Development, and Evaluation approach. We will include randomised clinical trials assessing piperacillin/tazobactam vs carbapenems in patients with severe bacterial infections of any origin. The primary outcome will be all-cause short-term mortality ≤ 90 days. Secondary outcomes will include all-cause long-term mortality > 90 days, adverse events, quality of life, use of life support, secondary infections, antibiotic resistance, and length of stay. We will conduct meta-analyses, including pre-planned subgroup and sensitivity analyses for all assessed outcomes. The risk of random errors in the meta-analyses will be assessed by trial sequential analysis.

Meta-Analysis
Zosyn (piperacillin-tazobactam; Pfizer Medical, New York, NY), a valuable antibiotic against gram-negative bacteria, combined with vancomycin (Z+V) is known for its high incidence of acute kidney injury (AKI), particularly in the intensive care unit (ICU), leading to the frequent use of alternatives for gram-negative coverage (Alt+V). Because there are limited data describing AKI on these alternative antibiotic agents, a systematic review and meta-analysis was conducted to determine if these regimens were indeed associated with decreased rates of AKI. A literature review was performed electronically from its inception to November 1, 2018, screening for relevant literature by title, abstract and full text according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines within the following databases: PubMed/Medline, CINAHL, Scopus, and Cochrane Central Register of Controlled Trials. Studies were included if they contained adults who had been admitted to the ICU for treatment and had received a combination of intravenous Z + V or Alt+V as well as had AKI measured during administration of these antibiotic agents. Studies were excluded if they represented pediatric populations, did not receive care in an ICU during their hospital admission, only received monotherapy for antibiotic treatment or received antibiotic treatment for less than 48 hours. Independent extraction was performed by two reviewers. Risk of bias was assessed using the Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I) methodology for retrospective studies. Random-effects models were used to calculate any differences between rates of AKI after Z + V or Alt + V. Fourteen articles (totaling 30,399 patients) were included. All studies available were retrospective in design. Compared with Alt + V, Z + V was associated with a higher risk ratio of AKI (1.79; 95% confidence interval [CI], 1.46-2.19; p < 0.001). Cefepime (C + V) was the most common alternative to Zosyn, and Z + V was associated with higher rates of kidney injury compared with C + V (1.70; 95% CI, 1.36-2.12; p < 0.00001). However, there was substantial heterogeneity in the data collected as well as high risk of bias. Zosyn plus vancomycin is associated with more risk of AKI compared with Alt+V coverage in ICU adult populations. However, the conclusions were limited by the retrospective nature of the studies, high bias of included articles, and heterogeneity of the included studies.

Meta-Analysis
OBJECTIVE
Piperacillin-tazobactam is a commonly used antibiotic in critically ill patients; however, controversy exists as to whether mortality in serious infections can be decreased through administration by prolonged infusion compared with intermittent infusion. The purpose of this systematic review and meta-analysis was to describe the impact of prolonged infusion piperacillin-tazobactam schemes on clinical endpoints in severely ill patients.
DESIGN
We conducted a systematic literature review and meta-analysis searching MEDLINE, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library from inception to April 1, 2017, for studies.
INTERVENTIONS
Mortality rates were compared between severely ill patients receiving piperacillin-tazobactam via prolonged infusion or intermittent infusion. Included studies must have reported severity of illness scores, which were transformed into average study-level mortality probabilities.
MEASUREMENTS AND MAIN RESULTS
Two investigators independently screened titles, abstracts, and full texts of studies meeting inclusion criteria for this systematic review and meta-analysis. Variables included author name, publication year, study design, demographics, total daily dose(s), average estimated creatinine clearance, type of prolonged infusion, prevalence of combination therapy, severity of illness scores, infectious sources, all-cause mortality, clinical cure, microbiological cure, and hospital and ICU length of stay. The review identified 18 studies including 3,401 patients who received piperacillin-tazobactam, 56.7% via prolonged infusion. Across all studies, the majority of patients had an identified primary infectious source. Receipt of prolonged infusion was associated with a 1.46-fold lower odds of mortality (95% CI, 1.20-1.77) in the pooled analysis. Patients receiving prolonged infusion had a 1.77-fold higher odds of clinical cure (95% CI, 1.24-2.54) and a 1.22-fold higher odds of microbiological cure (95% CI, 0.84-1.77). Subanalyses were conducted according to high (≥ 20%) and low (< 20%) average study-level mortality probabilities. In studies reporting higher mortality probabilities, effect sizes were variable but similar to the pooled results.
CONCLUSIONS
Receipt of prolonged infusion of piperacillin-tazobactam was associated with reduced mortality and improved clinical cure rates across diverse cohorts of severely ill patients.

Review
Street food may be a vehicle of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) to humans. Foods contaminated with ARB entail serious problems or challenges in the fields of medical care, animal husbandry, food industry, and public health worldwide. The objectives of this systematic review were to identify and evaluate scientific reports associated with ARB isolated from various street foods. "Preferred reporting items for systematic reviews and meta-analysis" (PRISMA) guidelines were followed. The bibliographic material covers a period from January 2015 to April 2024. Six electronic scientific databases were searched individually for full-text articles; only those papers that met the inclusion and exclusion criteria were selected. Seventeen papers were included in this systematic review. This study highlighted the wide distribution of ARB resistant to β-lactams and other antibiotics, posing significant health risks to consumers. High resistance levels were observed for antibiotics such as ampicillin, ceftriaxone, and tetracycline, while some antibiotics, such as ceftazidime, clavulanic acid, cefoperazone, cotrimoxazole, doxycycline, doripenem, fosfomycin, vancomycin, and piperacillin-tazobactam, demonstrated 100% susceptibility. The prevalence of ARB in street foods varied between 5.2% and 70.8% among different countries. The multiple resistance of various bacteria, including , , , and , to multiple classes of antibiotics, as well as environmental factors contributing to the spread of antibiotic resistance (AR), emphasize the urgent need for comprehensive approaches and coordinated efforts to confront antimicrobial resistance (AMR) under the "One Health" paradigm.

Meta-Analysis
BACKGROUND
As a tricyclic glycopeptide antibiotic used to treat acute infections, Vancomycin (VAN) is often administered with piperacillin/tazobactam (PT) to treat various infections in clinical practice. However, whether the combination of these two drugs, compared to VAN alone, can cause an increased risk of acute kidney injury (AKI) remains controversial.
OBJECTIVES
This study aims to identify the correlation between the development of AKI and the combined use of VAN and PT.
METHODS
We conducted a meta-analysis of eight observational cohort studies (a total of 10727 participants received VAN and PT versus VAN and other β-lactams). PubMed, Chinese Biological Medicine Database (CBM), China National Knowledge Infrastructure (CNKI) Database, Wan Fang Digital Periodicals Database (WFDP), and China Science Citation Database (CSCD) were searched through April 2017 using "vancomycin" and "piperacillin" and "tazobactam" as well as "acute kidney injury" or "acute renal failure" or "AKI" or "ARF" or "nephrotoxicity." Two reviewers extracted the data and assessed the risk of bias.
RESULTS
A correlation was found between the development of AKI and concurrent use of VAN and PT compared with concomitant VAN and β-lactams (OR 1.57; 95% CI, 1.13-2.01; I = 76.4%, p < 0.001). Similar findings were obtained in an analysis of studies comparing concurrent VAN and PT use with concurrent VAN and β-lactam (cefepime) use (OR 1.50; 95% CI, 1.07-1.93; I = 80.5%, p < 0.001). Exclusion of fair-quality and low-quality articles did not change the results (OR 1.49; 95% CI, 1.06-1.92; I = 84.1%, p < 0.001).
CONCLUSIONS
Regarding β-lactam therapy in clinical practice, an elevated risk of AKI due to the combined use of VAN and PT should be considered.
