Meta-Analysis
BACKGROUND
Vesicoureteral reflux (VUR) is one of the most common risk factors of urinary tract infection (UTI) among children. Various treatment modalities including antibiotic prophylaxis, surgical or endoscopic corrections and conservative treatment were used depending on the severity of VUR. The aim of this study is to compare the effectiveness of these treatment modalities in children with VUR grades II-IV by conducting a systematic review and network meta-analysis.
METHODS
A systematic search from different databases was performed from their earliest records to December 2022 without any language restriction. Only randomised controlled trials were included in this study. Effectiveness of treatment modalities was mainly compared by UTI. Other outcomes for renal scarring and resolution by renal units were also measured between treatments.
RESULTS
A total of 11 studies with 1447 children were included in this study. While comparing with antibiotic prophylaxis in network meta-analysis for UTI recurrence, surgical treatment probably lowers the rate of UTI recurrence (Log OR -0.26, 95% CI -0.54 to 0.02, high quality). However, endoscopic treatment (Log OR 0.2, 95% CI -1.41 to 1.81, high quality) and conservative treatment (Log OR 0.15, 95% CI -0.45 to 0.75, high quality) revealed probably inferior to antibiotic treatment.
CONCLUSION
Both pairwise and network meta-analytic results probably showed no difference between the treatments in terms of their impact on UTI recurrence, progression of previous renal scars, or formation of new renal scars in children with VUR grades II-IV. These findings may offer a better understanding of each treatment and evidence-based suggestions for the choice of treatment, which should be individualised and based on the patient's risk factors.

Review
In the era of antibiotic overuse and increasing antibiotic resistance, there is a gap in evidence regarding antibiotic stewardship, and in particular, perioperative antibiotic prophylaxis after urethral reconstruction. The aim of this systematic review was to evaluate the effectiveness and relevance of postoperative antibiotic prophylaxis after male pediatric and adult urethral reconstruction. An online search of MEDLINE database via PubMed was performed. The systematic review was registered in PROSPERO (CRD42022348555) and was conducted according to the PRISMA guidelines and AMSTAR 2 checklist. A narrative synthesis of included studies was performed. After the screening of 1176 publications, six studies regarding antibiotic prophylaxis after hypospadias reconstruction and two studies regarding antibiotic prophylaxis after urethroplasty in adults were eligible to be included in the systematic review. All but one of the studies on hypospadias repair showed no benefit from postoperative antibiotic prophylaxis. The level of evidence on postoperative antibiotic prophylaxis after urethroplasty in adults is low. Neither of the two studies included in the review showed a benefit from antibiotic use. Postoperative prophylaxis after hypospadias repair is not effective in preventing urinary tract infections and wound infections. It seems that the use of postoperative prophylaxis after urethroplasty in adults is also not beneficial, but there is a high need for high-quality scientific data.

Review
The worldwide prevalence of uncomplicated lower urinary tract infections (uUTIs) caused by multidrug-resistant Escherichia coli is increasing. To address this emergency, international guidelines recommend reducing administration of fluoroquinolones, in the context of growing resistance and the long-lasting and potentially disabling side effects of these drugs. The favoured drug to replace fluoroquinolones is fosfomycin trometamol (FT), a well-known derivate of phosphonic acid with broad-spectrum activity against Gram-negative and Gram-positive bacteria, including multidrug-resistant (MDR) strains. The European Committee on Antimicrobial Susceptibility Testing (EUCAST) recently reduced the susceptibility breakpoint for E. coli from 32 mg/L to 8 mg/L regarding FT used for uUTIs. This might lead to increased appropriate use of oral fosfomycin target therapy against E. coli and other microorganisms, and may be associated with a high likelihood of success. For species such as Klebsiella spp, particularly MDR strains, the absence of clinical breakpoints might lead to reduced use of oral fosfomycin, particularly if minimum inhibitory concentration is not available. To address this issue, this review presents an overview of the preclinical evidence on the activity of FT, and a systematic review of the clinical activity of FT in uUTIs in women, and in the prevention of infectious complications after prostate biopsy. The findings indicate that the safety and microbiological and clinical effectiveness of a single oral dose of FT are similar to that for comparator regimens with longer treatment schedules in women with uUTI, and FT can be considered a viable alternative to fluoroquinolones for antimicrobial prophylaxis in prostate biopsy. These observations and a broad clinical experience support the empirical use of FT for treating uUTI and indicate that FT is a promising candidate to effectively counteract antibiotic-resistant uUTIs throughout Europe.

Meta-Analysis
BACKGROUND
Spontaneous bacterial peritonitis (SBP) is a life-threatening complication in patients with advanced cirrhosis. Prophylactic Norfloxacin used to be considered effective in SBP prevention, but in recent years its efficacy has been partially compromised by increasing quinolone-resistant bacteria. However, whether the effects of alternative prophylactic regimens are superior to norfloxacin remains controversial. The goal of this study is to compare the effects of norfloxacin with other antibiotics in SBP prophylaxis for cirrhotic patients.
METHODS
We systematically searched Pubmed, Embase, and Cochrane Library Databases. Two reviewers independently identified relevant random control trials (RCTs) comparing the role of norfloxacin and other antibiotics in SBP prevention.
RESULTS
Eight studies comprising 1043 cirrhotic patients were included in this study. Norfloxacin and alternative antibiotics displayed comparable effects in SBP prophylaxis, survival benefit, overall infection prevention, and safety. Subgroup analyses revealed that rifaximin prophylaxis could reduce the recurrence of SBP with fewer adverse events but failed to improve overall survival compared with norfloxacin.
CONCLUSIONS
Other antibiotics are a reasonable alternative to norfloxacin in the prophylaxis of SBP. Rifaximin prophylaxis could be an alternative choose of antibiotic for SBP prevention because of its better protective effect and safety.

Review
INTRODUCTION
inappropriate use of antimicrobials is a cause for concern and contributes to the global antimicrobial resistance crises especially in Africa. This review aims to summarize the available evidence on the point prevalence and pattern of antimicrobial and/or antibiotic prescription in Africa.
METHODS
this review was carried out between April and September 2021 and identified published studies up until March 2021 on the point prevalence of antibiotic and/or antimicrobial use in Africa. Sources searched were OVID, PubMed, EMBASE, CINAHL, Web of Science, Google Scholar, Google, and African Journal Online (AJOL). Observational studies that reported prevalence published in English language were included. Covidence systematic review software was used for this review. A form for data extraction using domains culled from the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) was developed on Covidence. Screening of studies for eligibility was done independently by two reviewers. Critical Appraisal tool for use in Joanna Briggs Institute (JBI) Systematic Reviews for prevalence studies was used for quality appraisal.
RESULTS
a total of 17 studies that met the inclusion criteria were included in the review. The overall prevalence of antimicrobial/antibiotic use among inpatients in these studies ranged from 40.7% to 97.6%. The median antimicrobial/antibiotic use was 61.3 [IQR= 45.5-72.1]. The highest use of antimicrobials was reported among studies from Nigeria with a prevalence of 97.6%. The most prescribed antibiotics were the beta-lactam penicillin (Amoxicillin, clavulanic acid) (86.9%), and third generation cephalosporins (55.0%). There was general preference for parenteral route of administration of the antimicrobial agents (40-70%). Use for community acquired infections (28.0-79.5%) was the main reason for use. Majority of the prophylactic use of antimicrobial agents were for surgical prophylaxis. the high prevalence of antimicrobial use in Africa reinforces the need for continued surveillance and concerted efforts to institutionalize and support antimicrobial stewardship for prescribers in health institutions in the African region.

Meta-Analysis Review
Clinicians frequently prescribe systemic antibiotics after lower third molar extractions to prevent complications such as surgical site infections and dry socket. A systematic review of randomised clinical trials was conducted to compare the risk of dry socket and surgical site infection after the removal of lower third molars with different prophylactic antibiotics. The occurrence of any antibiotic-related adverse event was also analysed. A pairwise and network meta-analysis was performed to establish direct and indirect comparisons of each outcome variable. Sixteen articles involving 2158 patients (2428 lower third molars) were included, and the following antibiotics were analysed: amoxicillin (with and without clavulanic acid), metronidazole, azithromycin, and clindamycin. Pooled results favoured the use of antibiotics to reduce dry socket and surgical site infection after the removal of a lower third molar, with a number needed to treat of 25 and 18, respectively. Although antibiotic prophylaxis was found to significantly reduce the risk of dry socket and surgical site infection in patients undergoing lower third molar extraction, the number of patients needed to treat was high. Thus, clinicians should evaluate the need to prescribe antibiotics taking into consideration the patient's systemic status and the individual risk of developing a postoperative infection.

Meta-Analysis
OBJECTIVES
Infective endocarditis (IE) is a devastating disease with a 50% 1-year mortality rate. In recent years, medical authorities across the globe advised stricter criteria for antibiotic prophylaxis in patients with high risk of IE undergoing dental procedures. Whether such recommendations may increase the risk of IE in at-risk patients must be investigated.
DESIGN
Prospectively registered systematic review and meta-analysis.
DATA SOURCES
Medline, Embase, Scopus and ClinicalTrials.gov were searched through 23 May 2022, together with an updated search on 5 August 2023.
ELIGIBILITY CRITERIA
All primary studies reporting IE within 3 months of dental procedures in adults >18 years of age were included, while conference abstracts, reviews, case reports and case series involving fewer than 10 cases were excluded.
DATA EXTRACTION AND SYNTHESIS
All studies were assessed by two reviewers independently, and any discrepancies were further resolved through a third researcher.
RESULTS
Of the 3771 articles screened, 38 observational studies fit the inclusion criteria and were included in the study for subsequent analysis. Overall, 11% (95% CI 0.08 to 0.16, I=100%) of IE are associated with recent dental procedures. accounted for 69% (95% CI 0.46 to 0.85) of IE in patients who had undergone recent dental procedures, compared with only 21% (95% CI 0.17 to 0.26) in controls (p=0.003). None of the high-risk patients developed IE across all studies where 100% of the patients were treated with prophylactic antibiotics, and IE patients are 12% more likely to have undergone recent dental manipulation compared with matched controls (95% CI 1.00 to 1.26, p=0.048).
CONCLUSIONS
Although there is a lack of randomised control trials due to logistic difficulties in the literature on this topic, antibiotic prophylaxis are likely of benefit in reducing the incidence of IE in high-risk patients after dental procedures. Further well-designed high-quality case-control studies are required.

BACKGROUND
Periprosthetic joint infections (PJI) following joint arthroplasty are now the leading cause of reoperation and are associated with serious morbidity to the patient, often requiring several staged operations and a prolonged course of parenteral antibiotics. Prophylactic administration of intravenous antibiotics before skin incision is arguably the most important measure to prevent PJI; however, the dose effectiveness of cefazolin in target tissue is not well known. We aimed to identify parameters affecting local tissue concentration (LTC) of cefazolin.
METHODS
We performed a literature search using the following keywords: "orthopaedics," "orthopedic," "arthroplasty" and "cefazolin." We included studies that measured LTC of cefazolin from samples obtained during either a total knee or total hip arthroplasty.
RESULTS
Of the 332 records screened, we included 10 studies that described LTC of cefazolin. The included studies evaluated dosing ( = 7), procedure type ( = 3), body mass index ( = 1) and tourniquet utilization ( = 1).
CONCLUSION
Few studies have measured LTC levels of antibiotics (or levels of cefazolin) to validate current recommendations for antibiotic prophylaxis in orthopedic surgery. With infection as the leading reason for early reoperation or revision surgery, the parameters affecting LTC during orthopedic procedures need to be further assessed.

Review
BACKGROUND
Antibiotic prophylaxis in bicuspid aortic valve patients is currently a matter of debate. Although it is no longer recommended by international guidelines, some studies indicate a high risk of infective endocarditis. We aim to evaluate the risk of native valve infective endocarditis in bicuspid aortic valve patients and compare to individuals with tricuspid aortic valve.
METHODS
Study search of longitudinal studies regarding infective endocarditis incidence in bicuspid aortic valve patients (compared with tricuspid aortic valve/overall population) was conducted through OVID in the following electronic databases: MEDLINE, CENTRAL, EMBASE; from inception until October 2020. The outcomes of interest were the incidence rate and relative risk of infective endocarditis. The relative risk and incidence rate (number of cases for each 10 000 persons-year) with their 95 % confidence intervals (95 %CI) were estimated using a random effects model meta-analysis. The study protocol was registered at PROSPERO CRD42020218639.
RESULTS
Eight cohort studies were selected, with a total of 5351 bicuspid aortic valve patients. During follow up, 184 bicuspid aortic valve patients presented infective endocarditis, with an incidence rate of 48.13 per 10,000 patients-year (95 %CI 22.24-74.02), and a 12-fold (RR: 12.03, 95 %CI 5.45-26.54) increased risk compared with general population, after adjusted estimates.
CONCLUSIONS
This systematic review and meta-analysis suggests that bicuspid aortic valve patients have a significant high risk of native valve infective endocarditis. Large prospective high-quality studies are required to estimate more accurately the incidence of infective endocarditis, the relative risk and the potential benefit of antibiotic prophylaxis.

Review
: Group B streptococcus (GBS) is the leading cause of infections in neonates with high fatality rates. GBS is caused by the streptococcus bacterium known as streptococcus agalactiae, which is highly contagious and can be transmitted from pregnant women to infants. GBS infection can occur as an early onset or late-onset infection and has different treatment strategies. Antibiotics are effective in treating GBS infections at early stages. The aim of this systematic review was to summarize the clinical characteristics and treatment strategies for GBS, with a focus on antibiotics. : The findings of this review were reported in accordance with the PRISMA 2020 guidelines and a flow diagram of the study selection process, a summary of the included studies, a description of the study characteristics, a summary of the results, a discussion of the implications of the findings, and a conclusion are included. Overall, the authors followed a rigorous methodology to ensure that this review is comprehensive and inclusive of relevant studies on GBS infection and its treatment. : Overall, 940 studies were reviewed and only the most relevant 22 studies were included in the systematic review. This review describes the characteristics of patients in different studies related to early onset GBS disease and presents various treatment strategies and outcomes for GBS infection in pediatrics. The studies suggest that preventive measures, risk-based intrapartum antibiotic prophylaxis, and maternal vaccination can significantly reduce the burden of GBS disease, but late-onset GBS disease remains a concern, and more strategies are required to decrease its rate. Improvement is needed in the management of the risk factors of GBS. A conjugate vaccine with a serotype (Ia, Ib, II, III, and V) has been proven effective in the prevention of GBS in neonates. Moreover, penicillin is an important core antibiotic for treating early onset GBS (EOD). : This systematic review summarizes the treatment comparison for GBS infections in neonates, with a primary focus on antibiotics. IAP (intrapartum antibiotic prophylaxis) according to guidelines, antenatal screening, and the development of a conjugate vaccine may be effective and could lower the incidence of the disease.
