Review
BACKGROUND
Concerns exist regarding antibiotic prescribing for respiratory tract infections (RTIs) owing to adverse reactions, cost and antibacterial resistance. One proposed strategy to reduce antibiotic prescribing is to provide prescriptions, but to advise delay in antibiotic use with the expectation that symptoms will resolve first. This is an update of a Cochrane Review originally published in 2007, and updated in 2010, 2013 and 2017.
OBJECTIVES
To evaluate the effects on duration and/or severity of clinical outcomes (pain, malaise, fever, cough and rhinorrhoea), antibiotic use, antibiotic resistance and patient satisfaction of advising a delayed prescription of antibiotics in respiratory tract infections.
SEARCH METHODS
From May 2017 until 20 August 2022, this was a living systematic review with monthly searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL and Web of Science. We also searched the WHO International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov on 20 August 2022. Due to the abundance of evidence supporting the review's key findings, it ceased being a living systematic review on 21 August 2022.
SELECTION CRITERIA
Randomised controlled trials involving participants of all ages with an RTI, where delayed antibiotics were compared to immediate or no antibiotics. We defined a delayed antibiotic as advice to delay the filling of an antibiotic prescription by at least 48 hours. We considered all RTIs regardless of whether antibiotics were recommended or not.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures.
MAIN RESULTS
For this 2022 update, we added one new trial enrolling 448 children (436 analysed) with uncomplicated acute RTIs. Overall, this review includes 12 studies with a total of 3968 participants, of which data from 3750 are available for analysis. These 12 studies involved acute RTIs including acute otitis media (three studies), streptococcal pharyngitis (three studies), cough (two studies), sore throat (one study), common cold (one study) and a variety of RTIs (two studies). Six studies involved only children, two only adults and four included both adults and children. Six studies were conducted in primary care, four in paediatric clinics and two in emergency departments. Studies were well reported and appeared to provide moderate-certainty evidence. Randomisation was not adequately described in two trials. Four trials blinded the outcome assessor, and three included blinding of participants and doctors. We conducted meta-analyses for pain, malaise, fever, adverse effects, antibiotic use and patient satisfaction. Cough (four studies): we found no differences amongst delayed, immediate and no prescribed antibiotics for clinical outcomes in any of the four studies. Sore throat (six studies): for the outcome of fever with sore throat, four of the six studies favoured immediate antibiotics, and two found no difference. For the outcome of pain related to sore throat, two studies favoured immediate antibiotics, and four found no difference. Two studies compared delayed antibiotics with no antibiotic for sore throat, and found no difference in clinical outcomes. Acute otitis media (four studies): two studies compared immediate with delayed antibiotics - one found no difference for fever, and the other favoured immediate antibiotics for pain and malaise severity on Day 3. Two studies compared delayed with no antibiotics: one found no difference for pain and fever severity on Day 3, and the other found no difference for the number of children with fever on Day 3. Common cold (two studies): neither study found differences for clinical outcomes between delayed and immediate antibiotic groups. One study found delayed antibiotics were probably favoured over no antibiotics for pain, fever and cough duration (moderate-certainty evidence).
ADVERSE EFFECTS
there were either no differences for adverse effects or results may have favoured delayed over immediate antibiotics with no significant differences in complication rates (low-certainty evidence). Antibiotic use: delayed antibiotics probably resulted in a reduction in antibiotic use compared to immediate antibiotics (odds ratio (OR) 0.03, 95% confidence interval (CI) 0.01 to 0.07; 8 studies, 2257 participants; moderate-certainty evidence). However, a delayed antibiotic was probably more likely to result in reported antibiotic use than no antibiotics (OR 2.52, 95% CI 1.69 to 3.75; 5 studies, 1529 participants; moderate-certainty evidence). Patient satisfaction: patient satisfaction probably favoured delayed over no antibiotics (OR 1.45, 1.08 to 1.96; 5 studies, 1523 participants; moderate-certainty evidence). There was probably no difference in patient satisfaction between delayed and immediate antibiotics (OR 0.77, 95% CI 0.45 to 1.29; 7 studies, 1927 participants; moderate-certainty evidence). No studies evaluated antibiotic resistance. Reconsultation rates and use of alternative medicines were similar for delayed, immediate and no antibiotic strategies. In one of the four studies reporting use of alternative medicines, less paracetamol was used in the immediate group compared to the delayed group.
AUTHORS' CONCLUSIONS
For many clinical outcomes, there were no differences between prescribing strategies. Symptoms for acute otitis media and sore throat were modestly improved by immediate antibiotics compared with delayed antibiotics. There were no differences in complication rates. Delaying prescribing did not result in significantly different levels of patient satisfaction compared with immediate provision of antibiotics (86% versus 91%; moderate-certainty evidence). However, delay was favoured over no antibiotics (87% versus 82%). Delayed antibiotics achieved lower rates of antibiotic use compared to immediate antibiotics (30% versus 93%). The strategy of no antibiotics further reduced antibiotic use compared to delaying prescription for antibiotics (13% versus 27%). Delayed antibiotics for people with acute respiratory infection reduced antibiotic use compared to immediate antibiotics, but was not shown to be different to no antibiotics in terms of symptom control and disease complications. Where clinicians feel it is safe not to prescribe antibiotics immediately for people with RTIs, no antibiotics with advice to return if symptoms do not resolve is likely to result in the least antibiotic use while maintaining similar patient satisfaction and clinical outcomes to delayed antibiotics. Where clinicians are not confident in not prescribing antibiotics, delayed antibiotics may be an acceptable compromise in place of immediate prescribing to significantly reduce unnecessary antibiotic use for RTIs, while maintaining patient safety and satisfaction levels. Further research into antibiotic prescribing strategies for RTIs may best be focused on identifying patient groups at high risk of disease complications, enhancing doctors' communication with patients to maintain satisfaction, ways of increasing doctors' confidence to not prescribe antibiotics for RTIs, and policy measures to reduce unnecessary antibiotic prescribing for RTIs.

Review
BACKGROUND
Acute otitis media (AOM) is one of the most common diseases in childhood for which antibiotics are commonly prescribed; a systematic review reported a pooled prevalence of 85.6% in high-income countries. This is an update of a Cochrane Review first published in the Cochrane Library in 1997 and updated in 1999, 2005, 2009, 2013 and 2015.
OBJECTIVES
To assess the effects of antibiotics for children with AOM.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, Current Contents, CINAHL, LILACS and two trial registers. The date of the search was 14 February 2023.
SELECTION CRITERIA
We included randomised controlled trials comparing 1) antimicrobial drugs with placebo, and 2) immediate antibiotic treatment with expectant observation (including delayed antibiotic prescribing) in children with AOM.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened trials for inclusion and extracted data using the standard methodological procedures recommended by Cochrane. Our primary outcomes were: 1) pain at various time points (24 hours, two to three days, four to seven days, 10 to 14 days), and 2) adverse effects likely to be related to the use of antibiotics. Secondary outcomes were: 1) abnormal tympanometry findings, 2) tympanic membrane perforation, 3) contralateral otitis (in unilateral cases), 4) AOM recurrences, 5) serious complications related to AOM and 6) long-term effects (including the number of parent-reported AOM symptom episodes, antibiotic prescriptions and health care utilisation as assessed at least one year after randomisation). We used the GRADE approach to rate the overall certainty of evidence for each outcome of interest.
MAIN RESULTS
Antibiotics versus placebo We included 13 trials (3401 children and 3938 AOM episodes) from high-income countries, which we assessed at generally low risk of bias. Antibiotics do not reduce pain at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01; 5 trials, 1394 children; high-certainty evidence), or at four to seven days (RR 0.76, 95% CI 0.50 to 1.14; 7 trials, 1264 children), but result in almost a third fewer children having pain at two to three days (RR 0.71, 95% CI 0.58 to 0.88; number needed to treat for an additional beneficial outcome (NNTB) 20; 7 trials, 2320 children; high-certainty evidence), and likely result in two-thirds fewer having pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7; 1 trial, 278 children; moderate-certainty evidence). Antibiotics increase the risk of adverse events such as vomiting, diarrhoea or rash (RR 1.38, 95% CI 1.16 to 1.63; number needed to treat for an additional harmful outcome (NNTH) 14; 8 trials, 2107 children; high-certainty evidence). Antibiotics reduce the risk of children having abnormal tympanometry findings at two to four weeks (RR 0.83, 95% CI 0.72 to 0.96; NNTB 11; 7 trials, 2138 children), slightly reduce the risk of experiencing tympanic membrane perforations (RR 0.43, 95% CI 0.21 to 0.89; NNTB 33; 5 trials, 1075 children) and halve the risk of contralateral otitis episodes (RR 0.49, 95% CI 0.25 to 0.95; NNTB 11; 4 trials, 906 children). However, antibiotics do not reduce the risk of abnormal tympanometry findings at six to eight weeks (RR 0.89, 95% CI 0.70 to 1.13; 3 trials, 953 children) and at three months (RR 0.94, 95% CI 0.66 to 1.34; 3 trials, 809 children) or late AOM recurrences (RR 0.94, 95% CI 0.79 to 1.11; 6 trials, 2200 children). Severe complications were rare, and the evidence suggests that serious complications do not differ between children treated with either antibiotics or placebo. Immediate antibiotics versus expectant observation We included six trials (1556 children) from high-income countries. The evidence suggests that immediate antibiotics may result in a reduction of pain at two to three days (RR 0.53, 95% CI 0.35 to 0.79; NNTB 8; 1 trial, 396 children; low-certainty evidence), but probably do not reduce the risk of pain at three to seven days (RR 0.75, 95% CI 0.50 to 1.12; 4 trials, 959 children; moderate-certainty evidence), and may not reduce the risk of pain at 11 to 14 days (RR 0.91, 95% CI 0.75 to 1.10; 1 trial, 247 children; low-certainty evidence). Immediate antibiotics increase the risk of vomiting, diarrhoea or rash (RR 1.87, 95% CI 1.39 to 2.51; NNTH 10; 3 trials, 946 children; high-certainty evidence). Immediate antibiotics probably do not reduce the proportion of children with abnormal tympanometry findings at four weeks and evidence suggests that immediate antibiotics may not reduce the risk of tympanic membrane perforation and AOM recurrences. No serious complications occurred in either group.
AUTHORS' CONCLUSIONS
This review reveals that antibiotics probably have no effect on pain at 24 hours, a slight effect on pain in the days following and only a modest effect on the number of children with tympanic perforations, contralateral otitis episodes and abnormal tympanometry findings at two to four weeks compared with placebo in children with AOM. In high-income countries, most cases of AOM spontaneously remit without complications. The benefits of antibiotics must be weighed against the possible harms: for every 14 children treated with antibiotics, one child experienced an adverse event (such as vomiting, diarrhoea or rash) that would not have occurred if antibiotics were withheld. For most children with mild disease in high-income countries, an expectant observational approach seems justified. Therefore, clinical management should emphasise advice about adequate analgesia and the limited role for antibiotics.

Meta-Analysis Review
Performance evaluation of a PCR panel (FilmArray® Pneumonia Plus) for detection of respiratory bacterial pathogens in respiratory specimens: A systematic review and meta-analysis.
BACKGROUND
Accuracy and timing of antibiotic therapy remain a challenge for lower respiratory tract infections. New molecular techniques using Multiplex Polymerase Chain Reaction, including the FilmArray® Pneumonia Plus Panel [FAPP], have been developed to address this. The aim of this study is to evaluate the FAPP diagnostic performance for the detection of the 15 typical bacteria of the panel from respiratory samples in a meta-analysis from a systematic review.
METHODS
We searched PubMed and EMBASE from January 1, 2010, to December 31, 2022, and selected any study on the FAPP diagnostic performance on respiratory samples compared to the reference standard, bacterial culture. The main outcome was the overall diagnostic accuracy with sensitivity and specificity. We calculated the log Diagnostic Odds Ratio and analyzed performance for separate bacteria, antimicrobial resistance genes, and according to the sample type. We also reported the FAPP turnaround time and the out-of-panel bacteria number and species. This study is registered with PROSPERO (CRD42021226280).
RESULTS
From 10 317 records, we identified 30 studies including 8 968 samples. Twenty-one were related to intensive care. The overall sensitivity and specificity were 94% [95% Confidence Interval (CI) 91-95] and 98% [95%CI 97-98], respectively. The log Diagnostic Odds Ratio was 6.35 [95%CI 6.05-6.65]. 9.3% [95%CI 9.2-9.5] of bacteria detected in culture were not included in the FAPP panel.
CONCLUSION
This systematic review reporting the FAPP evaluation revealed a high accuracy. This test may represent an adjunct tool for pulmonary bacterial infection diagnostic and antimicrobial stewardship. Further evidence is needed to assess the impact on clinical outcome.

BACKGROUND
Although meningitis is largely preventable, it still causes hundreds of thousands of deaths globally each year. WHO set ambitious goals to reduce meningitis cases by 2030, and assessing trends in the global meningitis burden can help track progress and identify gaps in achieving these goals. Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we aimed to assess incident cases and deaths due to acute infectious meningitis by aetiology and age from 1990 to 2019, for 204 countries and territories.
METHODS
We modelled meningitis mortality using vital registration, verbal autopsy, sample-based vital registration, and mortality surveillance data. Meningitis morbidity was modelled with a Bayesian compartmental model, using data from the published literature identified by a systematic review, as well as surveillance data, inpatient hospital admissions, health insurance claims, and cause-specific meningitis mortality estimates. For aetiology estimation, data from multiple causes of death, vital registration, hospital discharge, microbial laboratory, and literature studies were analysed by use of a network analysis model to estimate the proportion of meningitis deaths and cases attributable to the following aetiologies: Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, group B Streptococcus, Escherichia coli, Klebsiella pneumoniae, Listeria monocytogenes, Staphylococcus aureus, viruses, and a residual other pathogen category.
FINDINGS
In 2019, there were an estimated 236 000 deaths (95% uncertainty interval [UI] 204 000-277 000) and 2·51 million (2·11-2·99) incident cases due to meningitis globally. The burden was greatest in children younger than 5 years, with 112 000 deaths (87 400-145 000) and 1·28 million incident cases (0·947-1·71) in 2019. Age-standardised mortality rates decreased from 7·5 (6·6-8·4) per 100 000 population in 1990 to 3·3 (2·8-3·9) per 100 000 population in 2019. The highest proportion of total all-age meningitis deaths in 2019 was attributable to S pneumoniae (18·1% [17·1-19·2]), followed by N meningitidis (13·6% [12·7-14·4]) and K pneumoniae (12·2% [10·2-14·3]). Between 1990 and 2019, H influenzae showed the largest reduction in the number of deaths among children younger than 5 years (76·5% [69·5-81·8]), followed by N meningitidis (72·3% [64·4-78·5]) and viruses (58·2% [47·1-67·3]).
INTERPRETATION
Substantial progress has been made in reducing meningitis mortality over the past three decades. However, more meningitis-related deaths might be prevented by quickly scaling up immunisation and expanding access to health services. Further reduction in the global meningitis burden should be possible through low-cost multivalent vaccines, increased access to accurate and rapid diagnostic assays, enhanced surveillance, and early treatment.

Meta-Analysis Review
Global prevalence of cefiderocol non-susceptibility in Enterobacterales, Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia: a systematic review and meta-analysis.
BACKGROUND
Cefiderocol is a last resort option for carbapenem-resistant (CR) Gram-negative bacteria, especially metallo-β-lactamase-producing Pseudomonas aeruginosa and CR Acinetobacter baumannii. Monitoring global levels of cefiderocol non-susceptibility (CFDC-NS) is important.
OBJECTIVES
To systematically collate and examine studies investigating in vitro CFDC-NS and estimate the global prevalence of CFDC-NS against major Gram-negative pathogens.
DATA SOURCES
PubMed and Scopus, up to May 2023.
STUDY ELIGIBILITY CRITERIA
Eligible were studies reporting CFDC-NS in Enterobacterales, P. aeruginosa, A. baumannii, or Stenotrophomonas maltophilia clinical isolates.
RISK-OF-BIAS ASSESSMENT
Two independent reviewers extracted study data and assessed the risk of bias on the population, setting, and measurement (susceptibility testing) domains.
DATA SYNTHESIS
Binomial-Normal mixed-effects models were applied to estimate CFDC-NS prevalence by species, coresistance phenotype, and breakpoint definition (EUCAST, CLSI, and FDA). Sources of heterogeneity were investigated by subgroup and meta-regression analyses.
RESULTS
In all, 78 studies reporting 82 035 clinical isolates were analysed (87% published between 2020 and 2023). CFDC-NS prevalence (EUCAST breakpoints) was low overall but varied by species (S. maltophilia 0.4% [95% CI 0.2-0.7%], Enterobacterales 3.0% [95% CI 1.5-6.0%], P. aeruginosa 1.4% [95% CI 0.5-4.0%]) and was highest for A. baumannii (8.8%, 95% CI 4.9-15.2%). CFDC-NS was much higher in CR Enterobacterales (12.4%, 95% CI 7.3-20.0%) and CR A. baumannii (13.2%, 95% CI 7.8-21.5%), but relatively low for CR P. aeruginosa (3.5%, 95% CI 1.6-7.8%). CFDC-NS was exceedingly high in New Delhi metallo-β-lactamase-producing Enterobacterales (38.8%, 95% CI 22.6-58.0%), New Delhi metallo-β-lactamase-producing A. baumannii (44.7%, 95% CI 34.5-55.4%), and ceftazidime/avibactam-resistant Enterobacterales (36.6%, 95% CI 22.7-53.1%). CFDC-NS varied considerably with breakpoint definition, predominantly among CR bacteria. Additional sources of heterogeneity were single-centre investigations and geographical regions.
CONCLUSIONS
CFDC-NS prevalence is low overall, but alarmingly high for specific CR phenotypes circulating in some institutions or regions. Continuous surveillance and updating of global CFDC-NS estimates are imperative while cefiderocol is increasingly introduced into clinical practice. The need to harmonize EUCAST and CLSI breakpoints was evident.

Meta-Analysis Review
OBJECTIVE
Various prophylactic antibiotic regimens are used in the management of preterm premature rupture of membranes. We investigated the efficacy and safety of these regimens in terms of maternal and neonatal outcomes.
DATA SOURCES
We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to July 20, 2021.
STUDY ELIGIBILITY CRITERIA
We included randomized controlled trials involving pregnant women with preterm premature rupture of membranes before 37 weeks of gestation and a comparison of ≥2 of the following 10 antibiotic regimens: control/placebo, erythromycin, clindamycin, clindamycin plus gentamicin, penicillins, cephalosporins, co-amoxiclav, co-amoxiclav plus erythromycin, aminopenicillins plus macrolides, and cephalosporins plus macrolides.
METHODS
Two investigators independently extracted published data and assessed the risk of bias with a standard procedure following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Network meta-analysis was conducted using the random-effects model.
RESULTS
A total of 23 studies that recruited a total of 7671 pregnant women were included. Only penicillins (odds ratio, 0.46; 95% confidence interval, 0.27-0.77) had significantly superior effectiveness for maternal chorioamnionitis. Clindamycin plus gentamicin reduced the risk of clinical chorioamnionitis, with borderline significance (odds ratio, 0.16; 95% confidence interval, 0.03-1.00). By contrast, clindamycin alone increased the risk of maternal infection. For cesarean delivery, no significant differences were noted among these regimens.
CONCLUSION
Penicillins remain the recommended antibiotic regimen for reducing maternal clinical chorioamnionitis. The alternative regimen includes clindamycin plus gentamicin. Clindamycin should not be used alone.

Meta-Analysis
BACKGROUND
We previously showed rising primary antibiotic resistance of Helicobacter pylori during 1990-2015 in the Asia-Pacific region. However, whether primary antibiotic resistance continues to rise is unknown. Therefore, we aimed to assess the latest prevalence of H pylori antibiotic resistance in this region.
METHODS
We did an updated systematic review and meta-analysis of observational studies and randomised controlled trials published in PubMed, Embase, and Cochrane Library between Jan 1, 1990, and July 12, 2023. Studies investigating primary H pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline in individuals naive to eradication therapy in the Asia-Pacific region (as defined by the UN geoscheme) were eligible for inclusion. There were no language restrictions. Studies that focused on specific subpopulations (eg, children) were excluded. Using a standardised extraction form, two authors independently reviewed and extracted summary data from all eligible articles. The updated prevalence of antibiotic resistance was generated by meta-analysis under a random-effects model and subgroup analyses were done by countries and periods of study. Between-study variability was assessed by use of I. The study is registered in PROSPERO, CRD42022339956.
FINDINGS
A total of 351 studies, including 175 new studies and 176 studies from our previous analysis, were included in this meta-analysis. The overall prevalence of primary antibiotic resistance of H pylori between 1990 and 2022 was 22% (95% CI 20-23; I=96%) for clarithromycin, 52% (49-55; I=99%) for metronidazole, 26% (24-29; I=96%) for levofloxacin, 4% (3-5; I=95%) for tetracycline, and 4% (3-5; I=95%) for amoxicillin. Prevalence varied considerably between countries and across study periods. From 1990 to 2022, the prevalence of primary resistance increased for clarithromycin, metronidazole, and levofloxacin but remained stable for amoxicillin and tetracycline. The latest primary resistance prevalences were 30% (95% CI 28-33; I=93%) for clarithromycin, 61% (55-66; I=99%) for metronidazole, 35% (31-39; I=95%) for levofloxacin, 4% (2-6; I=96%) for tetracycline, and 6% (4-8; I=96%) for amoxicillin in the Asia-Pacific region.
INTERPRETATION
Treatment guidelines should be adapted in response to the rising primary resistance of key antibiotics for H pylori eradication. A global policy to control and monitor the antibiotic resistance of H pylori is urgently needed.

Critical Care Medicine Nov 2023Fever is frequently an early indicator of infection and often requires rigorous diagnostic evaluation.
RATIONALE
Fever is frequently an early indicator of infection and often requires rigorous diagnostic evaluation.
OBJECTIVES
This is an update of the 2008 Infectious Diseases Society of America and Society (IDSA) and Society of Critical Care Medicine (SCCM) guideline for the evaluation of new-onset fever in adult ICU patients without severe immunocompromise, now using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology.
PANEL DESIGN
The SCCM and IDSA convened a taskforce to update the 2008 version of the guideline for the evaluation of new fever in critically ill adult patients, which included expert clinicians as well as methodologists from the Guidelines in Intensive Care, Development and Evaluation Group. The guidelines committee consisted of 12 experts in critical care, infectious diseases, clinical microbiology, organ transplantation, public health, clinical research, and health policy and administration. All task force members followed all conflict-of-interest procedures as documented in the American College of Critical Care Medicine/SCCM Standard Operating Procedures Manual and the IDSA. There was no industry input or funding to produce this guideline.
METHODS
We conducted a systematic review for each population, intervention, comparison, and outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the GRADE approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak or as best-practice statements.
RESULTS
The panel issued 12 recommendations and 9 best practice statements. The panel recommended using central temperature monitoring methods, including thermistors for pulmonary artery catheters, bladder catheters, or esophageal balloon thermistors when these devices are in place or accurate temperature measurements are critical for diagnosis and management. For patients without these devices in place, oral or rectal temperatures over other temperature measurement methods that are less reliable such as axillary or tympanic membrane temperatures, noninvasive temporal artery thermometers, or chemical dot thermometers were recommended. Imaging studies including ultrasonography were recommended in addition to microbiological evaluation using rapid diagnostic testing strategies. Biomarkers were recommended to assist in guiding the discontinuation of antimicrobial therapy. All recommendations issued were weak based on the quality of data.
CONCLUSIONS
The guidelines panel was able to formulate several recommendations for the evaluation of new fever in a critically ill adult patient, acknowledging that most recommendations were based on weak evidence. This highlights the need for the rapid advancement of research in all aspects of this issue-including better noninvasive methods to measure core body temperature, the use of diagnostic imaging, advances in microbiology including molecular testing, and the use of biomarkers.

Meta-Analysis
OBJECTIVES
The incidence of Helicobacter pylori (HP) is 25-50% in developed countries and 80% in developing countries, including 56.2% in China. However, antibiotic resistance of HP is a threat to HP control. The purpose of this study was to comprehensively evaluate primary drug resistance of HP in China.
METHODS
The full text of reports of the primary antibiotic resistance prevalence of HP was obtained from multiple databases (PubMed, Web of Science, Evimed, Cochrane Library, and China National Knowledge Internet). Review Manager 5.2 was adopted for meta-analysis, sensitivity analysis, and bias analysis. The Newcastle-Ottawa Scale was used to assess the article quality.
RESULTS
In total, 38804 HP samples from 22 trials were extracted. The results suggested that the overall prevalence of amoxicillin, clarithromycin, metronidazole, and levofloxacin resistance among HP in adults was as follows: mean difference (MD) = 1.35%, 95% confidence interval (CI) [1.03%, 1.68%]; MD = 23.76%, 95% CI [20.23%, 27.3%]; MD = 69.32%, 95% CI [64.85%, 73.8%]; and MD = 29.45%, 95% CI [4.90, 176.96], respectively. From the results of sensitivity and publication bias, we find that these results are robust and had little publication bias.
CONCLUSION
Our research showed that in China, the prevalence of HP resistance to primary antibiotics warrants attention, especially with regard to metronidazole, levofloxacin, and clarithromycin.

Review
BACKGROUND
In Ethiopia, salmonellosis is one of the most common zoonotic and foodborne illnesses. Ethiopia continues to be at risk for its fast-expanding medication resistance. For the development of preventative and control methods, summarized knowledge regarding salmonellosis is necessary. Determining a thorough evaluation of the prevalence, serotypes, and antibiotic resistance of in humans and animals from January 1, 2010, to December 30, 2022, in Ethiopia was our goal.
METHODS
To find related articles that published in English, we used the Google Scholar and PubMed search engines. Three researchers conducted the eligible studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, making sure to include the necessary keywords. If studies were duplicates, incomplete publications, or reported without an antimicrobial test were excluded. Excel 2013 was used to calculate frequencies and tabulate data.
RESULTS
There were a total of 43 investigations from food handlers, diarrhoeic patients, and animals. The prevalence rates ranged from 1% to 10% and 1% to 13% among food handlers and diarrhoea patients, respectively. The highest prevalence was among pigs (41.6%). S. Anatum in animals and S. Typhimurium in people were the predominant serotypes. Amoxicillin and ampicillin were claimed to be 100% resistant in human studies. The highest recorded resistances for ceftriaxone and ciprofloxacin were 16.7% and 100%, respectively. Animal studies revealed that resistances to ampicillin, streptomycin and tetracycline were 100%, 90%, 86.4%, respectively. S. Kentucky showed complete resistance to tetracycline, ampicillin, gentamicin, ciprofloxacin, and streptomycin.
CONCLUSION
The prevalence of among asymptomatic food handlers, diarrheal patients and animals were high in Ethiopia. S. Typhimurium that have the zoonotic importance was presented predominantly in human study. High levels of resistances were showed to tetracycline, ampicillin and streptomycin in animal studies. Salmonellosis prevention and control techniques should be strengthened.
