Review
is one of the world's leading causes of zoonotic and foodborne illnesses. Recently, antimicrobial resistance (AMR) has become one of the most critical challenges to public health and food safety. Herein, we employed a meta-analysis to determine the pooled prevalence and spatiotemporal distribution of serovars and antimicrobial resistance in NTS in Burkina Faso. To find eligible articles, a comprehensive literature search of PubMed, African Journals Online, ScienceDirect, Google Scholar, and the gray literature (university libraries) in Burkina was conducted for the period from 2008 to 2020. Studies meeting the inclusion criteria were selected and assessed for risk of bias. To assess the temporal and spatial relationships between serotypes and resistant strains from humans, animals, food, and the environment, a random-effects statistical model meta-analysis was carried out using the Comprehensive Meta-Analysis Version 3.0 program. The NTS prevalence rates were 4.6% (95% CI: 3-7) and 20.1% (95% CI: 6.6-47.4) in humans and animals, respectively, and 16.8% (95% CI: 10.5-25.8) and 15.6% (95% CI: 8.2-27.5) in food and the environment, respectively. Most NTS serovars were Derby, reported both in food and animals, and Typhimurium, reported in humans, while Croft II, Jodpur II, and Kentucky were the most prevalent in the environment. NTS isolates were highly resistant to erythromycin, amoxicillin, cefixime, and cephalothin, with a pooled prevalence of multidrug resistance of 29% (95% CI: 14.5-49.5). The results of this review show a high diversity of serotypes, as well as high antibiotic resistance in isolates from animal, human, food, and environmental samples in Burkina, calling for a consolidated "One Health" approach to better understand the drivers of pathogen emergence, spread, and antimicrobial resistance, as well as the formulation of intervention measures needed to limit the risk associated with the disease.

BACKGROUND
Ten % of the population is labeled as allergic to penicillin(s), when in fact 90% of these labels are inappropriate. Recent studies have shown that inpatient de-labelling by a direct drug challenge (dDC) is safe in low-risk patients. However, there is a need for outpatient and non-allergist de-labelling.
OBJECTIVE
To assess the safety of de-labelling low-risk adults by means of dDC in primary care.
METHODS
We searched MEDLINE, EMBASE and the Conchrane Library databases, from inception to March 15, 2022 (updated June 5, 2023) for studies performing dDC in adults in primary care or other outpatient settings. Two researchers independently screened studies for eligibility. The data extraction and critical appraisal was performed by one reviewer and we pooled the results in a meta-analysis.
RESULTS
Out of 2,138 results, 12 studies (1070 participants) were eligible for inclusion. Three studies evaluated de-labelling in primary care and 9 studies in an outpatient hospital setting. There were no critical adverse events during dDC. No reaction occurred in 97.13% of the 1070 patients, who previously labeled as penicillin-allergic, and were safely de-labelled. Ten patients (<1%) developed an immediate reaction: three had self-limiting reactions, and seven needed antihistaminics, steroids, epinephrine and/or salbutamol.
CONCLUSION
No serious allergic reactions are observed during direct amoxicillin challenge in adults in an outpatient setting. However, with the exception of one recent report, these studies are of low to moderate quality. Non-specialist de-labelling is promising but further research is required on correct risk stratification and safety assessment in large cohort studies evaluating dDC in primary care.

Meta-Analysis Review
BACKGROUND
The amoxicillin dose used in dual therapy to eradicate Helicobacter pylori varies across studies and the optimal amoxicillin dose for vonoprazan-based dual therapies remains unclear. We aimed to investigate the efficacy and safety of low- and high-dose amoxicillin in vonoprazan-amoxicillin dual therapy.
MATERIALS AND METHODS
A comprehensive systematic review was conducted by searching databases from inception to October 2023. All trials that evaluated the effectiveness and safety of vonoprazan-amoxicillin dual therapy for eradicating H. pylori were included. Pooled eradication rate, incidence of adverse events, relative risks, and 95% confidence intervals are presented.
RESULTS
Eighteen studies with 12 low-dose amoxicillin (VLA) and 13 high-dose amoxicillin (VHA) arms were included. The pooled eradication rates were 82.4% and 86.8% for VLA therapy, and 86.0% and 90.9% for VHA therapy by the intention-to-treat and per-protocol analyses, respectively. In the subgroup analysis stratified by duration, the eradication rates achieved in 7 days, 10 days, and 14 days treatments with VLA and VHA dual therapies were 80.8%, 84.2%, 83.1%, and 67.3%, 88.8%, 87.5%, respectively. In the four randomized controlled trials that directly compared VLA and VHA dual therapies, the efficacy was not statistically different in the intention-to-treat (76.9% vs 81.4%, p = 0.337) and per-protocol (81.6% vs 84.0%, p = 0.166) analyses. Additionally, the incidence of adverse events (p = 0.965) and compliance (p = 0.994) were similar in both groups.
CONCLUSION
VLA therapy demonstrated comparable efficacy and safety to VHA therapy, along with regional differences. An appropriately extended treatment duration may be critical for therapeutic optimization of vonoprazan-amoxicillin treatment.

Meta-Analysis Review
INTRODUCTION
Due to irregular antibiotic use, the rate of antibiotic resistance to Helicobacter pylori (H. pylori) is increasing and varies from region to region. Therefore, for the purpose of further clarifying the changes in antibiotic resistance rates nowadays, we conducted a systematic review and meta-analysis to update and assess the 10-year trend of primary H. pylori antibiotic resistance rate to the commonly prescribed antibiotics worldwide.
MATERIALS AND METHODS
According to the PRISMA statement, we systematically searched electronic databases for studies that assessed rates of H. pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline published from 2013 to 2023. AHRQ was adopted to estimate methodological quality and publication bias in the included studies, and statistical analysis was performed using Stata 17.0.
RESULTS
We identified 163 studies, comprising 47,002 isolates from 36 countries. The meta-analysis showed that the primary antibiotic resistance rate of H. pylori varied widely among antibiotics. Subgroup analysis showed higher rates of antibiotic resistance in the adult population than in children, and a general trend of increased resistance was observed from 2013 to 2023. There was considerable heterogeneity (I > 75%) among all analyses, which may be due to high variability in resistance rates across the global regions.
CONCLUSIONS
Resistance of H. pylori to antibiotics has reached alarming levels worldwide, which has a great effect on the efficacy of treatment. Local surveillance networks are required to select appropriate eradication regimens for each region.

Meta-Analysis Review
BACKGROUND
This study aims to evaluate the efficacy and safety of vonoprazan-amoxicillin (VA), vonoprazan-amoxicillin-clarithromycin (VAC), vonoprazan-based bismuth-containing quadruple therapy (VBQT), and PPI-based triple (PAC) or quadruple therapy (PBQT) for H. pylori infection with the consideration of duration of therapy and amoxicillin dose (H: high; L: low).
MATERIALS AND METHODS
PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched for eligible randomized controlled trials (RCTs) up to December 15, 2023. The efficacy outcome was eradication rate, and safety outcomes included the rates of adverse events and treatment discontinuation.
RESULTS
Twenty-seven RCTs were included. The pooled eradication rates were 82.8% for VA, 89.1% for VAC, and 91.8% for VBQT, which increased with the higher amoxicillin frequency of administration and extended duration of therapy within each regimen. There were no significant differences in eradication rate when comparing 7-VA versus 7-VAC and 14-VA versus 14-VAC. VA was at least comparable to PAC. The eradication rate did not differ significantly between 10-H-VA or 14-H-VA versus 14-PBQT. 7-L-VAC demonstrated higher eradication rate versus 7-PAC and comparable rate to 14-PAC. 14-VBQT showed higher eradication rates versus 14-PBQT. The adverse events rate was 19.3% for VA, 30.6% for VAC, and 38.4% for VBQT. VA had similar risk of adverse events versus VAC and significantly fewer adverse events compared to PBQT. The treatment discontinuation rate did not differ significantly between treatments.
CONCLUSIONS
The eradication rate of VBQT was the highest at above 90% followed by VAC and VA. VA was as effective as VAC and superior to PPI-based therapies with favorable safety, highlighting the potential of VA therapy as a promising alternative to traditional PPI-based therapies. VPZ-based triple or quadruple therapies was more effective than PPI-based therapies. Further studies are needed to establish the optimal treatment regimen especially in the western countries.

Review
BACKGROUND
Antimicrobial resistance (AMR) is a serious threat to global health systems. is a major cause of urinary tract infections (UTIs). Understanding the AMR patterns of uropathogenic (UPEC) is crucial for effective public health interventions worldwide.
OBJECTIVES
This systematic review and meta-analysis aimed to consolidate existing research and provide a comprehensive information on AMR UPEC in Ethiopia.
METHODS
We systematically searched databases such as PubMed, Web of Science, and Science Direct, along with including articles from Google Scholar. Data were extracted into Microsoft Excel and analysed using STATA 17.0. Cohen's kappa was computed to assess reviewer agreement, while the I statistic evaluated heterogeneity. Egger's tests were conducted to detect publication bias, and random-effects models were utilized to estimate the pooled resistance, with AMR rates for each antibiotic pooled separately.
RESULTS
UPEC showed resistance rates, ranging from 3.64% (95% CI: -4.38% to 11.67%) for amikacin to 85.32% (95% CI: 78.6%-92.04%) for ampicillin. Highest resistance was to ampicillin (85.32%), followed by amoxicillin at 82.52% (95% CI: 74.3%-90.74%), tetracycline at 60.67% (95% CI: 51.53%-69.81%) and trimethoprim/sulfamethoxazole at 57.17% (95% CI: 49.93%-64.42%). Conversely, resistance rates were lower for amikacin at 3.64% and meropenem at 5.26% (95% CI: 2.64%-7.88%). UPEC demonstrated a pooled MDR rate of 79.17% (95% CI: 70.32%-88.01%) and a pooled ESBL production rate of 29.16% (95% CI: 22.36%-38.55%).
CONCLUSIONS
High levels of AMR were observed in UPEC strains, highlighting a critical public health issue requiring urgent action through robust antimicrobial stewardship and surveillance to preserve effective UTI treatment options.

Review
To compare the effectiveness of pre-operative and post-operative administration of amoxicillin in patients undergoing third molar extraction surgery. A systematic search was executed according to PRISMA guidelines for studies published till December 2021. Studies were included based on the pre-eligibility criteria. The risk of bias was assessed using the Cochrane risk of bias tool. The heterogeneity was evaluated, and a random effect model was used for meta-analysis. A total of five studies were included from an initial search of 96 studies. The included studies were randomized controlled trials and comparative studies assessing pre-operative and post-operative administration of antibiotics among patients undergoing third molar extraction surgery. For comparison between pre-operative and post-operative groups, interincisal distance, complications, pain, and swelling were systematically reviewed and meta-analysis was done for interincisal distance and complications. The mean change in interincisal distance ranged from 5.5 to 47.9 and from 4.56 to 46.1 in the pre-operative and post-operative amoxicillin groups, respectively. Complications reported were infections, alveolar osteitis, nausea, diarrhea, gastric pain, rash, and headache with a pooled incidence of 4.3-33% in the pre-operative amoxicillin group and 0-22.7% in the post-operative amoxicillin group. Quantitative synthesis of data carried out from meta-analysis shows a significant difference in the pre-operative and post-operative amoxicillin groups in improving the interincisal distance and incidence of complications post surgery. The qualitative synthesis of data derived from systematic review for pain provides favoring results for post-operative amoxicillin administration. In case of swelling, a non-conclusive result was obtained.

Review
BACKGROUND
Drowning-associated pneumonia (DAP) is frequent in drowned patients, and possibly increases mortality. A better understanding of the microorganisms causing DAP could improve the adequacy of empirical antimicrobial therapy. We aimed to describe the pooled prevalence of DAP, the microorganisms involved, and the impact of DAP on drowned patients.
METHODS
Systematic review and meta-analysis of studies published between 01/2000 and 07/2023 reporting on DAP occurrence and microorganisms involved.
RESULTS
Of 309 unique articles screened, 6 were included, involving 688 patients. All were retrospective cohort studies, with a number of patients ranging from 37 to 270. Studies were conducted in Europe (France N = 3 and Netherland N = 1), United States of America (N = 1) and French West Indies (N = 1). Mortality ranged between 18 to 81%. The pooled prevalence of DAP was 39% (95%CI 29-48), similarly following freshwater (pooled prevalence 44%, 95%CI 36-52) or seawater drowning (pooled prevalence 42%, 95%CI 32-53). DAP did not significantly impact mortality (pooled odds ratio 1.43, 95%CI 0.56-3.67) but this estimation was based on two studies only. Respiratory samplings isolated 171 microorganisms, mostly Gram negative (98/171, 57%) and mainly Aeromonas sp. (20/171, 12%). Gram positive microorganisms represented 38/171 (22%) isolates, mainly Staphylococcus aureus (21/171, 12%). Water salinity levels had a limited impact on the distribution of microorganisms, except for Aeromonas sp. who were exclusively found following freshwater drowning (19/106, 18%) and never following seawater drowning (0%) (p = 0.001). No studies reported multidrug-resistant organisms but nearly 30% of the isolated microorganisms were resistant to amoxicillin-clavulanate, the drug that was the most commonly prescribed empirically for DAP.
CONCLUSIONS
DAP are commonly caused by Gram-negative bacteria, especially Aeromonas sp. which is exclusively isolated following freshwater drowning. Empirical antimicrobial therapy should consider covering them, noting than amoxicillin-clavulanate may be inadequate in about one-third of the cases. The impact of DAP on patients' outcome is still unclear.

Antimicrobial resistance in bacterial wound, skin, soft tissue and surgical site infections in Central, Eastern, Southern and Western Africa: A systematic review and meta-analysis.
Antimicrobial resistance (AMR) is a major global threat and AMR-attributable mortality is particularly high in Central, Eastern, Southern and Western Africa. The burden of clinically infected wounds, skin and soft tissue infections (SSTI) and surgical site infections (SSI) in these regions is substantial. This systematic review reports the extent of AMR from sampling of these infections in Africa, to guide treatment. It also highlights gaps in microbiological diagnostic capacity. PubMed, MEDLINE and Embase were searched for studies reporting the prevalence of Staphylococcus aureus, Eschericheria coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii in clinically infected wounds, SSTI and SSI in Central, Eastern, Southern or Western Africa, and studies reporting AMR from such clinical isolates. Estimates for proportions were pooled in meta-analyses, to estimate the isolation prevalence of each bacterial species and the proportion of resistance observed to each antibiotic class. The search (15th August 2022) identified 601 articles: 59 studies met our inclusion criteria. S. aureus was isolated in 29% (95% confidence interval [CI] 25% to 34%) of samples, E. coli in 14% (CI 11% to 18%), K. pneumoniae in 11% (CI 8% to 13%), P. aeruginosa in 14% (CI 11% to 18%) and A. baumannii in 8% (CI 5% to 12%). AMR was high across all five species. S. aureus was resistant to methicillin (MRSA) in >40% of isolates. E. coli and K. pneumoniae were both resistant to amoxicillin-clavulanic acid in ≥80% of isolates and resistant to aminoglycosides in 51% and 38% of isolates respectively. P. aeruginosa and A. baumannii were both resistant to anti-pseudomonal carbapenems (imipenem or meropenem) in ≥20% of isolates. This systematic review found that a large proportion of the organisms isolated from infected wounds, SSTI and SSI in Africa displayed resistance patterns of World Health Organisation (WHO) priority pathogens for critical or urgent antimicrobial development.

BACKGROUND
The present systematic review aims to investigate the guidelines for prescribing Preventive Antibiotic Therapy (PAT) in the placement of dental implants (DIs) without anatomical constraints in healthy patients by clinicians in Europe and to compare them with current recommendations.
MATERIAL AND METHODS
A search was performed in 4 databases: Medline (via PubMed), Web of Science, Scopus, and LILACS. The criteria employed were those described in the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) declaration (PROSPERO Registration number: CRD42022382278).
RESULTS
The electronic search identified 10 studies published between 2010 and 2023 that met the established criteria. Overall, 60.8% ± 24.1% of European professionals routinely prescribe PAT, with the most frequent regimen being perioperative (mean= 46.7% ± 24.3%), followed by postoperative PAT only (mean= 20.3% ± 9.7%).
CONCLUSIONS
The most commonly prescribed antibiotic both pre- and postoperatively is amoxicillin and, in allergic patients, clindamycin. In Europe, more doses of PAT are being prescribed than suggested by current recommendations. For this reason, more PAT education is needed in educational curricula to promote a more rational use of antibiotics to reduce the occurrence of antimicrobial resistance.
