Abstract
INTRODUCTION The escalating threat of multidrug-resistant organisms necessitates constant exploration for novel antimicrobial agents. Eravacycline, a next-generation tetracycline derivative, has emerged as a promising solution due to its unique chemical structure, which enhances potency and expands its spectrum of activity. AREA COVERED This review provides a thorough examination of eravacycline, encompassing its in vitro activity against Gram-positive and Gram-negative aerobes, carbapenem-non-susceptible organisms, anaerobes, and other bacterial strains. Additionally, it evaluates evidence from clinical studies to establish its clinical effect and safety. EXPERT OPINION Eravacycline, a synthetic fluorocycline, belongs to the tetracyclines class with a basic chemical structure, and specific modifications were introduced on the D ring of the naphtacen nucleus. Similar to other tetracycline, eravacycline exerts its antibacterial action by reversibly binding to the bacterial ribosomal 30S subunit, preventing the incorporation of amino acid residues into elongating peptide chains and ultimately disrupting bacterial protein synthesis. Eravacycline demonstrates potent in vitro activity against many Gram-positive and Gram-negative aerobes, anaerobes, and multidrug-resistant organisms. Randomized controlled trials and its associated meta-analysis affirms eravacycline's efficacy in treating complicated intra-abdominal infections. Moreover, real-world studies showcase eravacycline's adaptability and effectiveness in diverse clinical conditions, emphasizing its utility beyond labeled indications. Despite common gastrointestinal adverse events, eravacycline maintains an overall favorable safety profile, reinforcing its status as a tolerable antibiotic. However, ongoing research is essential for refining eravacycline's role, exploring combination therapy, and assessing its performance against biofilms, contributing to its continued success in combating challenging bacterial infections.

Abstract
BACKGROUND Monitoring the trends of pre-treatment drug resistance (PDR) and resistance-associated mutations (RAMs) among antiretroviral-naïve people with HIV (PWH) is important for the implementation of HIV treatment and control programmes. We analysed the trends of HIV-1 PDR after the introduction of second-generation integrase strand-transfer inhibitors (INSTIs) in 2016 in Taiwan, when single-tablet regimens of non-nucleoside reverse-transcriptase inhibitor (NNRTI-) and INSTI-based antiretroviral therapy became the preferred treatments. MATERIALS AND METHODS In this multicentre study, we included newly diagnosed, antiretroviral-naïve PWH who underwent tests for RAMs between 2016 and 2022. Pre-treatment genotypic resistance testing was performed, along with HIV-1 subtyping and determinations of plasma HIV RNA load and CD4 lymphocyte counts. RAMs were analysed using the Stanford University HIV Drug Resistance Database and only RAMs conferring at least low-level resistance were included. RESULTS From 2016 to 2022, pre-treatment blood samples from 3001 newly diagnosed PWH, which constituted 24.3% of newly diagnosed PWH in Taiwan during the study period, were tested. Of the PWH with analysable gene sequences, the HIV-1 PDR prevalence to NNRTIs, nucleoside reverse-transcriptase inhibitors (NRTIs), first- and second-generation INSTIs and PIs was 10.0%, 2.1%, 2.5%, 0.6% and 0.4%, respectively. While the trends of PDR remained stable for NRTIs, INSTIs and PIs, there was a significantly increasing trend of PDR to NNRTIs from 6.0% in 2016% to 13.1% in 2022 (P = 0.001). CONCLUSIONS After the introduction of second-generation INSTIs in Taiwan, the trends of HIV-1 PDR to NRTIs and INSTIs remained low. Furthermore, there was no significant decrease of the prevalence of PDR toward NNRTIs between 2016 and 2022.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has contributed to the spread of antimicrobial resistance, including carbapenem-resistant Enterobacterales. METHODS This study utilized data from the Study for Monitoring Antimicrobial Resistance Trends (SMART) surveillance program in Taiwan. Enterobacterales from patients with bloodstream infections (BSIs) were collected and subjected to antimicrobial susceptibility testing and β-lactamase gene detection using a multiplex PCR assay. Statistical analysis was conducted to compare susceptibility rates and resistance genes between time periods before (2018-2019) and during the COVID-19 pandemic (2020-2021). RESULTS A total of 1231 Enterobacterales isolates were collected, predominantly Escherichia coli (55.6%) and Klebsiella pneumoniae (29.2%). The proportion of nosocomial BSIs increased during the COVID-19 pandemic (55.5% vs. 61.7%, p < 0.05). Overall, susceptibility rates for most antimicrobial agents decreased, with Enterobacterales from nosocomial BSIs showing significantly lower susceptibility rates than those from community-acquired BSIs. Among 123 Enterobacterales isolates that underwent molecular resistance mechanism detection, ESBL, AmpC β-lactamase, and carbapenemase genes were detected in 43.1%, 48.8% and 16.3% of the tested isolates, respectively. The prevalence of carbapenemase genes among carbapenem-resistant Enterobacterales increased during the pandemic, although the difference was not statistically significant. Two novel β-lactamase inhibitor combinations, imipenem-relebactam and meropenem-vaborbactam, preserved good efficacy against Enterobacterales. However, imipenem-relebactam showed lower in vitro activity against imipenem-non-susceptible Enterobacterales than that of meropenem-vaborbactam. CONCLUSIONS The COVID-19 pandemic appears to be associated with a general decrease in antimicrobial susceptibility rates among Enterobacterales causing BSIs in Taiwan. Continuous surveillance is crucial to monitor antimicrobial resistance during the pandemic and in the future.

Abstract
OBJECTIVE We aimed to assess the efficacy of cefoperazone/sulbactam (CPZ/SUL) in extended-spectrum β-lactamase (ESBL)-producing Enterobacterales infections and identify factors influencing outcomes. METHODS This retrospective multicentre study was conducted in Taiwan (January 2015 to December 2020) and examined the efficacy of CPZ/SUL treatment in ESBL-producing Enterobacterales bacteraemia. The minimum inhibitory concentrations (MICs) were determined using agar dilution; ESBL/AmpC genes were detected using polymerase chain reaction. The primary outcome was clinical success, whereas the secondary outcome was 30-day mortality. Clinical success was defined as the complete resolution of clinical signs and symptoms of K. pneumoniae or E. coli infection, with no evidence of persistent or recurrent bacteraemia. The factors influencing outcomes were identified using a multivariate analysis. RESULTS CPZ/SUL demonstrated a clinical success rate of 82.7% (91/110) in treating ESBL-producing Enterobacterales bacteraemia, with a 30-day mortality rate of 9.1% (10/110). Among 110 ESBL-producing isolates, a high clinical success rate was observed at an MIC of ≤32/32 mg/L. Multivariate analysis revealed that a Charlson comorbidity index (CCI) of ≥6 was associated with lower clinical success [odds ratio (OR): 5.80, 95% confidence interval (CI): 1.15-29.14, P = 0.033]. High Sequential Organ Failure Assessment scores (≥6) were significantly associated with increased 30-day mortality (OR: 14.34, 95% CI: 1.45-141.82, P = 0.023). DISCUSSION CPZ/SUL demonstrated a clinical success rate of 82.7% (91/110) in treating ESBL-producing Enterobacterales bacteraemia. Treatment success was evident when the CPZ and SUL MIC was ≤32/32 mg/L. Comorbidities (CCI ≥6) were associated with lower clinical success, while disease severity (Sequential Organ Failure Assessment score ≥6) correlated with higher mortality.

Abstract
OBJECTIVES WHO has recommended same-day antiretroviral therapy (SDART) initiation since 2017; however, higher attrition rates were noted in developing countries. METHODS We included newly diagnosed people with HIV (PWH) from 2018 to 2022 at 18 hospitals around Taiwan. SDART initiation was defined as starting ART on the same day of HIV diagnosis and rapid initiation as starting ART within 14 days of diagnosis. A composite unfavorable outcome was defined as death after 30 days of diagnosis, loss to follow-up (LTFU), or virologic failure or rebound at 12 months. RESULTS At 12 months, PWH on SDART initiation and those on rapid ART initiation showed similar rates of engagement in care with plasma HIV-1 RNA <50 copies/mL (87.5% vs 87.7%) and composite unfavorable outcome (7.7% vs 7.7%). PWH aged >30 years were less likely to have LTFU (aHR 0.44, 95% CI 0.28-0.70). PWH aged >30 years (aHR 0.59, 95% CI 0.41-0.85) and gay, bisexual, and men who have sex with men (GBMSM) (aHR 0.50, 95% CI 0.32-0.79) were less likely to have composite unfavorable outcomes. CONCLUSIONS SDART and rapid ART initiation resulted in comparable clinical outcomes and viral suppression rates. PWH aged >30 years and GBMSM were less likely to have unfavorable outcomes.

Abstract
Background The association between N-acetylcysteine (NAC) and COVID-19 remains undetermined; therefore, this meta-analysis assessed the clinical efficacy of NAC in the treatment of patients with COVID-19. Methods This study searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov for studies published from their inception to December 17, 2022. Only randomized controlled trials (RCTs) that assessed the clinical efficacy of NAC for patients with COVID-19 were included. Results Five RCTs involving 651 patients were included. There was no significant difference in mortality between the study group receiving NAC and the control group (15.6 % [50/320] vs. 32.3 %, [107/331]; risk ratio [RR]: 0.58; 95 % confidence interval [CI]: 0.24-1.40). In addition, the two groups did not differ with respect to the incidence of invasive mechanical ventilation (RR: 0.93; 95 % CI: 0.65-1.33), the risk of intensive care unit (ICU) admission (RR: 0.86; 95 % CI: 0.62-1.21), the length of hospital stay (mean difference [MD]: 0.17 days; 95 % CI: -0.67-1.01), and the length of ICU stay (MD: -0.77 days; 95 % CI: -2.97-1.42). Conclusions The administration of NAC did not improve the clinical outcomes of patients with COVID-19; its routine use is not recommended for patients with SARS-CoV-2 infections.

Abstract
IMPORTANCE Elizabethkingia anophelis, a Gram-negative pathogen, causes infections such as bacteraemia, pneumonia, and neonatal meningitis. The pathogen resists most antimicrobial classes, making novel approaches urgently needed. In natural settings, Gram-negative bacteria secrete outer membrane vesicles (OMVs) that carry important molecules in the bacterial life cycle. These OMVs are enriched with proteins involved in virulence, survival, and carbohydrate metabolism, making them a promising source for vaccine development against the pathogen. This study investigated the efficacy of imipenem-induced OMVs (iOMVs) as a vaccine candidate against E. anophelis infection in a mouse pneumonia model. Mice immunized with iOMVs were completely protected during lethal-dose challenges. Passive immunization with hyperimmune sera and splenocytes conferred protection against lethal pneumonia. Further investigation is needed to understand the mechanisms underlying the protective effects of iOMV-induced passive immunity, such as the action on specific antibody subclasses or T cell subsets.

Abstract
BACKGROUND Real-world experience with combinations of short-course rifapentine-based regimens and integrase strand-transfer inhibitor (InSTI)-containing antiretroviral therapy (ART) in management of latent tuberculous infection (LTBI) is limited among people with HIV (PWH). METHODS From August 2019 to October 2022, PWH receiving 3 months of weekly rifapentine plus isoniazid (3HP) or 1 month of daily rifapentine plus isoniazid (1HP) in combination with ART were included. The primary outcome was virologic response within 12 months after LTBI treatment, and the secondary outcomes included treatment completion rate and safety of LTBI regimens. RESULTS During the study period, 479 PWH (94.6% male; median age, 43 years) were included: 142 received 1HP and bictegravir (BIC)-containing regimens (1HP/BIC group), 46 1HP and dolutegravir (DTG)-containing regimens (1HP/DTG group), 38 3HP and BIC-containing regimens (3HP/BIC group), 214 3HP and DTG-containing regimens (3HP/DTG group), 17 1HP and other ART regimens (1HP/others group), and 22 3HP/other ART regimens (3HP/others group). In the intention-to-treat analysis, the proportions of PWH maintaining plasma HIV-1 RNA <200 copies/mL within 12 months after LTBI treatment completion were 96.5% (1HP/BIC), 100% (1HP/DTG), 100% (3HP/BIC), 95.8% (3HP/DTG), 100% (1HP/others), and 100% (3HP/others). The overall completion rates were >80% for all treatment groups, whereas >50% of the included PWH experienced any adverse event. LTBI regimens and ART combinations were not associated with virologic response and completion rate. CONCLUSION Combinations of short-course rifapentine-based regimens and InSTI-containing ART maintained viral suppression for most PWH within 12 months of LTBI treatment completion with low rates of grade 3 or higher adverse events.

Abstract
BACKGROUND Enterobacterales carrying blaNDM represent an emerging challenge in treating infectious diseases. In this study, we aimed to investigate the characteristics of blaNDM-producing Enterobacterales from three hospitals in southern Taiwan. METHODS Enterobacterales strains that were nonsusceptible to more than one carbapenem (ertapenem, meropenem, imipenem, or doripenem) were collected from hospitalized patients. Molecular typing for New Delhi metallo-β-lactamase (NDM) and antibiotic susceptibility tests were performed, followed by multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), and plasmid analysis by PCR-based replicon typing. RESULTS A total of 1311 carbapenem-nonsusceptible Enterobacterales were isolated from 2017 to 2021. blaNDM-encoding genes were detected in 108 isolates, with 53 (49.1%) harboring blaNDM-1 and 55 (50.9%) harboring blaNDM-5. The rate of blaNDM-1 detection among isolates decreased to 2% in 2021. However, the rate of E. coli harboring blaNDM-5 increased from 1% to 12% of total isolates during the study period. Of 47 NDM-5-positive E. coli isolates, 44 (93.6%) were ST8346 with high genetic relatedness. E. coli ST8346 isolates showed high-level resistance to both carbapenems and aminoglycosides. Most (38 out of 47, 80.9%) blaNDM-5-harboring E. coli isolates co-harbored blaOXA-181. We analyzed the regions harboring blaNDM-5 in E. coli ST8346 via PCR amplification. blaNDM-5 and blaOXA-181 were located on two separate plasmids, IncF and IncX3, respectively. CONCLUSION The dissemination of E. coli ST8346 caused an increase in blaNDM-5 and blaOXA-181 co-harboring Enterobacterales in southern Taiwan, which show high-level resistance to both carbapenems and aminoglycosides. We identified a distinct IncF plasmid encoding blaNDM-5 that has the potential for rapid spread and needs further surveillance.

Abstract
BACKGROUND The efficacy of inhaled corticosteroid (ICS) in the treatment of patients with COVID-19 has been evaluated in randomized controlled trials (RCTs), however, their findings are not consistent. METHODS PubMed, Embase, Cochrane Library, ClinicalTrials.gov, Scopus, Web of Science and Google Scholar were searched to June 10, 2023. Only RCTs that investigated the clinical efficacy and safety of ICS for patients with COVID-19 were included. RESULTS Eleven RCTs were included. ICS users had significantly higher rate of symptom alleviation at day 14 than the control group (risk ratio [RR], 1.13; 95% CI, 1.04-1.23; I2 = 42%). Additionally, no significant difference between the ICS users and the control group was observed in the composite outcome of urgent care, emergency department (ED) visit or hospitalization (RR, 0.43; 95% CI, 0.08-2.48; I2 = 85%) and hospitalization or death (RR, 0.85; 95% CI, 0.64-1.12; I2 = 0%). Finally, ICS user had a non-significantly lower risk of death at day 28 than the control group (0.63% vs 0.99%; RR, 0.82; 95% CI, 0.43-1.56; I2 = 0%). CONCLUSIONS Additional ICS use, particularly inhaled budesonide may help symptom relief in patients with COVID-19. However, ICS use did not help reduce the risk of urgent care, ED visit, hospitalization, or death.

Abstract
BACKGROUND In Taiwan, the prevalence of COVID-19 was low before April 2022. The low SARS-CoV-2 seroprevalence in the population of Taiwan provides an opportunity for comparison with fewer confounding factors than other populations globally. Cycle threshold (Ct) value is an easily accessible method for modeling SARS-CoV-2 dynamics. In this study, we used clinical samples collected from hospitalized patients to explore the Ct value dynamics of the Omicron variant infection. METHODS From Jan 2022 to May 2022, we retrospectively included hospitalized patients tested positive by nasopharyngeal SARS-CoV-2 PCR. We categorized the test-positive subjects into different groups according to age, vaccination status, and use of antiviral agents. To investigate the nonlinear relationship between symptom onset days and Ct value, a fractional polynomial model was applied to draw a regression line. RESULTS We collected 1718 SARS-CoV-2 viral samples from 812 individuals. The Ct values of unvaccinated individuals were lower than those of vaccinated persons from Day 4 to Day 10 after symptom onset. The Ct value increased more rapidly in those individuals with antiviral drug treatment from Day 2 to Day 7. In elderly individuals, the Ct values increased slowly from Day 5 to Day 10, and the increasing trend was unique compared with that in children and adults. CONCLUSION Our study demonstrated the primary viral infection dynamics of the Omicron variant in hospitalized patients. Vaccination significantly affected viral dynamics, and antiviral agents modified viral dynamics irrespective of vaccination status. In elderly individuals, viral clearance is slower than that in adults and children.

Abstract
Purpose To investigate the antibiotic susceptibility of Escherichia coli isolates in patients diagnosed with intra-abdominal infections (IAIs) in the Asia-Pacific region. Patients and Methods This study was conducted at 50 medical hospitals across 9 countries/regions as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART) surveillance program from 2014 to 2018. Nonduplicate isolates of aerobic and facultative gram-negative bacilli were collected and processed for further antimicrobial susceptibility testing. Results A total of 10,709 isolates were collected, with E. coli (n=4737, 44.2%) being the leading pathogen causing IAIs, followed by Klebsiella pneumoniae (n=2429, 22.7%) and Pseudomonas aeruginosa (n=931, 8.7%). Community-associated (CA) E. coli isolates generally exhibited higher susceptibility rates for most antibiotics than hospital-associated (HA) isolates. In countries/regions other than Hong Kong, South Korea, and Singapore, HA isolates displayed lower susceptibility rates for multiple classes (≥4) of antibiotics. Among the commonly used antibiotics in IAIs, the overall susceptibility rate for ciprofloxacin was low, with an average of 41.3%. Ceftriaxone susceptibility rates in all selected countries were below 80% starting in 2018, ranging from 23.3% to 75.8%. The cefepime susceptibility rates varied across regions, with consistently reduced susceptibility ranging from 45.5% to 57.8% in India, Thailand, and Vietnam. Piperacillin/tazobactam demonstrated effectiveness against E. coli isolates in almost all countries except India, with a downward trend observed in the Philippines and Taiwan. Carbapenems remained effective against more than 90% of E. coli isolates, except in India. Conclusion Prudent use of fluoroquinolones and ceftriaxone is advised when treating both CA and HA IAIs in the Asia-Pacific region. The low susceptibility rate of cefepime in India, Thailand, and Vietnam needs careful consideration in its administration. Moreover, the increase in nonsusceptibility to piperacillin/tazobactam in the Philippines and Taiwan poses a potential risk that should be closely monitored.

Abstract
Objectives To investigate the in vitro activity of antibiotic combinations against Stenotrophomonas maltophilia isolates and their associated biofilms. Methods Thirty-two S. maltophilia clinical isolates with at least twenty-five different pulsotypes were tested. The antibacterial activity of various antibiotic combinations against seven randomly selected planktonic and biofilm-embedded S. maltophilia strains with strong biofilm formation was assessed using broth methods. Extraction of bacterial genomic DNA and PCR detection of antibiotic resistance and biofilm-related genes were also performed. Results The susceptibility rates of levofloxacin (LVX), fosfomycin (FOS), tigecycline (TGC) and sulfamethoxazole-trimethoprim (SXT) against 32 S. maltophilia isolates were 56.3, 71.9, 71.9 and 90.6%, respectively. Twenty-eight isolates were detected with strong biofilm formation. Antibiotic combinations, including aztreonam-clavulanic (ATM-CLA) with LVX, ceftazidime-avibactam (CZA) with LVX and SXT with TGC, exhibited potent inhibitory activity against these isolates with strong biofilm formation. The antibiotic resistance phenotype might not be fully caused by the common antibiotic-resistance or biofilm-formation gene. Conclusion S. maltophilia remained resistant to most antibiotics, including LVX and β-lactam/β-lactamases; however, TGC, FOS and SXT still exhibited potent activity. Although all tested S. maltophilia isolates exhibited moderate-to-strong biofilm formation, combination therapies, especially ATM-CLA with LVX, CZA with LVX and SXT with TGC, exhibited a higher inhibitory activity for these isolates.

Abstract
Data regarding the durability of tenofovir alafenamide (TAF)-containing antiretroviral therapy (ART) in maintaining hepatitis B virus (HBV) viral suppression among HIV/HBV-coinfected patients are limited. Between February and October 2018, 274 HIV/HBV-coinfected participants who had achieved HIV RNA of <50 copies/mL with tenofovir disoproxil fumarate (TDF)-containing ART and switched to elvitegravir/cobicistat/emtricitabine/TAF were prospectively enrolled. Serial plasma HIV and HBV viral loads, HBV and hepatitis D virus (HDV) serology, renal parameters, metabolic profiles, and bone mineral density (BMD) were assessed through 96 weeks. At baseline and weeks 48, 72, and 96, 5.8%, 5.1%, 5.8%, and 5.1% of the participants had plasma HBV DNA of ≥20 IU/mL, and 0%, 0.7%, 1.5%, and 2.2% had HIV RNA of ≥50 copies/mL, respectively. Hepatitis B surface antigen (HBsAg) loss occurred in 1.5% of 274 participants, and hepatitis B e-antigen (HBeAg) loss or seroconversion occurred in 14.3% of 35 HBeAg-positive participants. Compared with baseline, the median urine protein-to-creatinine ratio (79 versus 63 mg/g, P < 0.001) and β2-microglobulin-to-creatinine ratio (165 versus 83 μg/g, P < 0.001) continued to decrease at week 96. BMD of the spine and hip slightly increased (mean change, +0.9% and +0.5%, respectively). The median triglycerides, total cholesterol, low-density lipoprotein (LDL)-cholesterol and high-density lipoprotein (HDL)-cholesterol increased from baseline to week 96 (116 versus 141, 166 versus 190, 99 versus 117, and 42 versus 47 mg/dL, respectively; all P < 0.001), and most of the increases occurred in the first 48 weeks of the switch. Our study showed that switching from TDF-containing ART to elvitegravir/cobicistat/emtricitabine/TAF maintained HBV and HIV viral suppression through 96 weeks among HIV/HBV-coinfected patients. Proteinuria continued to improve, while fasting lipids increased and BMD stabilized at 96 weeks after the switch. IMPORTANCE Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide as a maintenance therapy showed durable and high rates of viral suppression for HIV/HBV-coinfected patients, with only 5.1% and 2.2% of patients having HBV DNA of ≥20 IU/mL and HIV RNA of ≥50 copies/mL, respectively, at 96 weeks. Our study fills the data gap on the long-term clinical effectiveness of tenofovir alafenamide-containing antiretroviral therapy in people living with HIV who have HBV coinfection.

Abstract
Purpose The vicious cycle of recurrent cellulitis ultimately results in a high risk of relapse, which facilitates the use of antibiotic prophylaxis with monthly intramuscular benzathine penicillin G (BPG) to prevent recurrence. However, several clinical situations hinder the guideline recommendations in daily practice. Therefore, intramuscular clindamycin has been used as an alternative in our institution for years. This study aims to elucidate the effectiveness of monthly intramuscular antibiotics in preventing further cellulitis recurrence and evaluate the applicability of intramuscular clindamycin as an alternative to BPG. Patients and Methods A retrospective cohort study was conducted at a medical center in Taiwan from January 2000 to October 2020. Adult patients with recurrent cellulitis were enrolled to receive monthly intramuscular antibiotic prophylaxis (including 1.2-2.4MU BPG or 300-600mg intramuscular clindamycin) or to be observed without prophylaxis. The decision to administer prophylaxis or observe was made at the discretion of the examining infectious disease specialists. Cox proportional-hazards regressions were performed to estimate hazard ratios (HR) and adjust for variables between groups. The Kaplan-Meier method was used to estimate survival curves. Results Enrollment in the study consisted of 426 patients, with 222 receiving BPG, 106 receiving intramuscular clindamycin, and 98 being observed without prophylaxis. Both types of antibiotics resulted in a significantly lower recurrence rate than observation alone (27.9% for BPG, 32.1% for intramuscular clindamycin, and 82.7% for observation, P < 0.001). After adjusting for multiple variables, antibiotic prophylaxis continued to significantly reduce the risk of cellulitis recurrence by 82% (HR 0.18, 95% CI 0.13 to 0.26), by 86% (HR 0.14, 95% CI 0.09 to 0.20) with BPG, and by 77% (HR 0.23, 95% CI 0.14 to 0.38) with intramuscular clindamycin. Conclusion Monthly intramuscular antibiotic prophylaxis was demonstrated to be effective in reducing cellulitis recurrence. Moreover, in the real-world practice, intramuscular clindamycin may serve as a reasonable alternative option to BPG.

Abstract
Background People living with HIV (PLWH) have an increased risk of developing cardiovascular diseases (CVD). As speckle-tracking echocardiography (STE) has been used to detect subclinical myocardial abnormalities, this study aims to detect early cardiac impairment among Asian PLWH using STE and to investigate the associated risk factors. Methods We consecutively recruited asymptomatic PLWH without previous CVD from a medical center of Taiwan, and their cardiac function was evaluated by conventional echocardiogram and STE. Enrolled PLWH were classified as antiretroviral therapy (ART)-experienced and ART-naive, and multivariable regressions were used to assess the association between myocardial strain and risk factors including traditional CVD and HIV-associated factors. Results A total of 181 PLWH (mean age: 36.4 ± 11.4 years, 173 males) were recruited and conventional echocardiogram parameters were within normal ranges. Decreased myocardial strain across the myocardium was found, with a mean left ventricular (LV) global longitudinal strain of -18.7 ± 2.9%. The LV strain in the ART-experienced group (-19.0 ± 2.9%) was significantly better than the ART-naive group (-17.9 ± 2.8%), despite a younger age and lesser CVD risk factors in the ART-naive group. Hypertension [B = 1.92, 95% confidence interval (95% CI) 0.19-3.62, p = 0.029] and ART-naive with both low and high viral loads (VL) (B = 1.09, 95% CI 0.03-2.16, p = 0.047; and B = 2.00, 95% CI, 0.22-3.79, p = 0.029) were significantly associated with reduced myocardial strain. Conclusion This is the first and largest cohort using STE to investigate myocardial strain in Asian PLWH. Our results suggest that hypertension and detectable VL are associated with impaired myocardial strain. Thus, timely ART administration with VL suppression and hypertension control are crucial in preventing CVD when making the management parallel with the improved life expectancy of PLWH on ART.

Abstract
BACKGROUND Carbapenem-sparing antibiotic is urgently needed for patients with complicated intra-abdominal infections (cIAIs). Even though several novel antibiotics - novel β-lactam-β-lactamase inhibitor combinations - ceftolozane-tazobactam and ceftazidime-avibactam, and novel tetracycline derivative - eravacycline have been developed for cIAIs, whether these antibiotics are comparable to carbapenem for cIAIs remain unclear. METHODS A comprehensive search was conducted on PubMed, Embase, Cochrane Library, and ClinicalTrials.gov until October 1, 2022. Only RCTs that compared the clinical efficacy and safety of novel antibiotic against carbapenem for patients with cIAIs were included. RESULTS Among 11 selected RCTs, no significant differences were observed in terms of clinical cure rate at test of cure between the study and the control group in the analysis of clinical evaluable population (93.6% vs 93.7%, risk ratio [RR], 1.00; 95% CI, 0.98-1.01; p = 0.84), microbiologically evaluable population (93.0% vs 94.5%; RR, 0.98; 95% CI, 0.96-1.00; p = 0.10), and modified intention-to-treat population (85.9% vs 87.7%; RR, 0.98; 95% CI, 0.95-1.01; p = 0.13). All these findings remain consistent across the subgroup analyses and sensitivity tests. Similarly, there were no significant differences in terms of microbiological eradication between the study and the control group (87.8% vs 89.7%; RR, 0.98; 95% CI, 0.96-1.01; p = 0.18). The risks of adverse events were similar between groups. CONCLUSIONS The clinical efficacy, microbiological response, and safety of the novel antibiotics, including ceftazidime-avibactam, ceftolozane-tazobactam, and eravacycline are comparable to carbapenem in the treatment of patients with cIAI. These agents can be potential therapeutic options as carbapenem-sparing antibiotic for cIAIs.

Abstract
OBJECTIVE This meta-analysis aimed at assessing the clinical efficacy and safety of novel antibiotics for complicated urinary tract infections (cUTIs). METHODS Three electronic databases including Medline, Embase, and Cochrane library were searched from inception till October 20, 2022 to identify randomized controlled trials (RCTs) investigating the efficacy and safety of novel antibiotics (including novel β-lactam/β-lactamase inhibitor combinations, aminoglycoside, fluoroquinolone, and cefiderocol) against cUTIs. The primary outcome was the clinical cure rate (CCR) at test of cure (TOC), while secondary outcomes included CCR at end of treatment (EOT), microbiological eradication rate, and the risk of adverse events (AEs). Trial sequential analysis (TSA) was used to examine the evidence. RESULTS A total of eleven RCTs demonstrated a higher CCR (83.6% vs 80.3%; odds ratio [OR]=1.37; 95%CI:1.08-1.74; p=0.01, I2 = 35%, 11 RCTs, 3514 participants) and microbiological eradication rate (77.7% vs 67.2%; OR=1.79; 95%CI:1.46-2.20; p<0.00001, 11 RCTs, 4347 participants) at TOC in the intervention group than those in the controls. There was no significant difference between the intervention and control groups in CCR at EOT (OR=0.96; p=0.81, I2=4%, nine RCTs, 3429 participants) and risk of treatment-emergent AE (OR=0.95; p=0.57, I2=51%; 11RCTs, 5790 participants). TSA showed robust evidence regarding microbiological eradication rate and treatment-emergent AEs, while the CCR at TOC and EOT remained inconclusive. CONCLUSIONS While showing similar safety, the investigated novel antibiotics may be more effective than the conventional ones for patients with cUTIs. However, as the pooled evidence relating to CCR remained inconclusive, further studies are required to address this issue.

Abstract
BACKGROUND Both ertapenem and other carbapenems, including imipenem, meropenem, and doripenem, are recommended in the treatment of extended-spectrum-β-lactamase (ESBL)-producing Enterobacterales infection. However, whether ertapenem is as effective as other carbapenems for ESBL-producing Enterobacterales remains unclear. Therefore, this meta-analysis was conducted to compare the clinical efficacy of ertapenem versus other carbapenems in the treatment of ESBL-producing Enterobacterales infection. METHODS PubMed, Web of Science, and Cochrane Library were searched from their inception to November 29, 2022. Only studies comparing ertapenem and other carbapenems in the treatment of patients with ESBL-producing Enterobacterales infections were included. RESULTS A total of 6 studies meeting the selection criteria were identified. Overall, ertapenem was associated with a significantly lower 30-day mortality when compared with other carbapenems (10.7% [46/431] vs 17.7% [104/586]; risk ratio [RR], 0.61; 95% CI: 0.40-0.91). The ertapenem group exhibited a significantly shorter length of hospital stay than the other carbapenems groups (mean differences, -6.02 days; 95% CI, -9.39 to -2.64). No significant differences were noted between the ertapenem and other carbapenems groups in terms of the rates of clinical cure or improvement (RR, 1.11; 95% CI: 0.97-1.25) and microbiological eradication (RR, 1.01; 95% CI: 0.97-1.06). CONCLUSIONS Ertapenem could be as effective as other carbapenems in the treatment of patients with ESBL-producing Enterobacterales infections.

Abstract
OBJECTIVES This study was conducted to assess the clinical efficacy of probiotics in the treatment of patients with COVID19. METHODS PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched for studies from their inception to 8 February 2022. Randomized controlled trials (RCTs) that compared the clinical efficacy of probiotics with usual care or standard care for patients with COVID19 were included. The primary outcome was all-cause mortality. Random-effects model using MantelHaenszel and inverse variance methods were performed to analyze the data. RESULTS Eight RCTs with 900 patients were included. The study group receiving probiotics had a non-significantly lower rate of mortality than the control group had, but this difference was not significant (risk ratio [RR], 0.51; 95% CI, 0.22 to 1.16). However, the study group had significantly lower rates of dyspnea (RR, 0.11; 95% CI, 0.02 to 0.60), fever (RR, 0.37; 95% CI, 0.16 to 0.85) and headache (RR, 0.19; 95% CI, 0.05 to 0.65). Higher complete remission of COVID-19-associated symptoms was observed in the study group than the control group (RR, 1.89; 95% CI, 1.40-2.55). CONCLUSIONS Although probiotics use did not improve clinical outcomes or reduce inflammatory markers, it may relieve COVID-19-associated symptoms.

Abstract
BACKGROUND Streptococcus gallolyticus subsp. pasteurianus (SGSP) is a commensal in the intestinal tract and a potential pathogen of neonatal sepsis. During an 11-month period, four consecutive cases of SGSP sepsis were identified in one postnatal care unit (unit A) without evidence of vertical transmission. Therefore, we initiated this study to investigate the reservoir and mode of transmission of SGSP. METHOD We performed cultures of stool samples from healthcare workers in unit A and unit B (another unit without SGSP sepsis). If SGSP was positive in feces, we performed isolate pulsotyping and genotyping by using pulsed-field gel electrophoresis (PFGE) and analyzing random amplified polymorphic DNA (RAPD) patterns, respectively. RESULTS Five staff members in unit A showed positivity for SGSP. All samples from unit B were negative. We identified two major pulsogroups (groups C and D) by PFGE. In group D, the strains isolated from 3 consecutive sepsis patients (P1, P2 and P3) were closely related and clustered together as those from 2 staff members (C1/C2, C6). One staff (staff 4) had a direct contact history with patient (P1) confirmed to have the same clone. The last isolate of the patient in our study (P4) belonged to a distinct clone. CONCLUSION We found prolonged gut colonization of SGSP in healthcare workers and its epidemiological relatedness to neonatal sepsis. Fecal-oral or contact transmission is a possible route of SGSP infection. Fecal shedding among staff may be associated with neonatal sepsis in healthcare facilities.

Abstract
BACKGROUND Extraintestinal Pathogenic Escherichia coli (ExPEC) is a leading cause of invasive disease, including bacteremia and sepsis. Invasive ExPEC disease (IED) has the potential to complicate the clinical treatment of other conditions and is associated with an increased mortality, hospitalization, and worse outcomes. Older adults and individuals with comorbid conditions are at higher risk of IED. ExPEC is of particular concern in the Asia Pacific region due to aging populations and rising antimicrobial resistance. OBJECTIVES This study aimed to synthesize most recent data on the epidemiology, clinical and economic burden of IED in the elderly/high risk populations in China, Japan, South Korea, Taiwan, and Australia. METHODS A targeted literature review was conducted using Embase, Medline, as well as local scientific databases. We included studies published in English and local languages published from January 1, 2010 to October 7, 2020 that were relevant to the research objectives. Studies were narratively synthesized. RESULTS A total of 1,047 studies were identified and 34 of them were included in this review. ExPEC accounted for 46.0% (1,238/2,692) of bacteria-related invasive diseases in patients aged above 60 years in South Korea, followed by China (44.4% (284/640)), Taiwan (39.0% (1,244/3,194)), and Japan (18.1% (581/3,206)), while Australia reported ExPEC out of all pathogens (54.7% (4,006/7,330)) in general adults. Comorbidities such as diabetes or cancer were common in these patients. Studies reported increases in length-of-stay, and in-hospital 30-day all-cause mortality related to ExPEC associated bacteremia was between 9% to 12%. From a cost perspective, a 3-fold increase in sepsis-associated cost was reported in South Korea between 2005 and 2012. In Australia, antimicrobial resistance contributed to an additional cost of AUD $5.8 million per year (95% uncertainty interval [UI], $2.2-$11.2 million) in the treatment of bloodstream infections (BSIs). CONCLUSION ExPEC was a major cause of blood stream infection across China, Japan, South Korea, Taiwan, and Australia. Both the clinical and economic burden associated to ExPEC infections as well as the antimicrobial resistance observed in the elderly call for preventive and curative actions in these regions.

Abstract
Objectives This study investigated the inhibitory effect of Lactobacillus spp. with prebiotics against Klebsiella pneumoniae carbapenemase-2 (KPC-2)-producing Klebsiella pneumoniae using both in vitro experiments and animal models. Methods Thirty-three Lactobacillus spp. strains were confirmed by 16S rDNA sequencing, and four different PFGE genotyped KPC-2-producing K. pneumoniae strains were selected for investigation. In vitro studies, including broth microdilution assays, changes in pH values in lactobacilli cultures with different prebiotics, time-kill tests of Lactobacillus spp. against KPC-2-producing K. pneumoniae and further in vivo Lactobacillus alone or in combination with prebiotics against KPC-2-producing K. pneumoniae in an animal model, were performed. Results The lower pH value of the cell-free supernatant was associated with a lower minimal inhibitory percentage of the Lactobacillus strain against KPC-2-producing K. pneumoniae. Furthermore, lactulose/isomalto-oligosaccharide/inulin and fructo-oligosaccharide can enhance the inhibitory effect of all 107 CFU/ml Lactobacillus strains against KPC001. Three Lactobacillus strains (LYC1154, LYC1322, and LYC1511) that could be persistently detected in the stool were tested for their ability to reduce the amount of KPC001 in the feces individually or in combination. A significantly better effect in reducing the amount of KPC001 was observed for the combination of three different Lactobacillus species than for each of them alone. Furthermore, their inhibitory effect was enhanced after adding lactulose or isomalto-oligosaccharide (both p < 0.05). Conclusion This study demonstrates the inhibitory effect of probiotic Lactobacillus, including LYC1154, LYC1322, and LYC1511, with prebiotics such as lactulose or isomalto-oligosaccharide against the colonization of KPC-2-producing K. pneumoniae.

Abstract
BACKGROUND In Taiwan, there were only 799 confirmed COVID-19 cases in 2020. The unique backdrop amidst a pandemic and promotion of nonpharmaceutical interventions generated some distinct changes in the epidemiology of common respiratory pathogens. In this study, we aimed to investigate the dynamic changes in respiratory pathogens in children during 2020. METHODS We performed a retrospective cohort study at a tertiary hospital in southern Taiwan during 2020. Patients aged 0-18 years who visited the pediatric emergency department were enrolled. Children who presented with clinical symptoms (fever or respiratory illness) and received nasopharyngeal swabs for multiplex polymerase chain reaction (PCR) were included in our analysis. We also compared respiratory syncytial virus (RSV) trends from previous years by PCR and lateral flow immunochromatographic assays from 2017 to 2020. RESULTS A total of 120 children were tested. The overall detection rate was 55%. With strengthened restrictions, the detection rate dropped from 70% to 30%. However, non-enveloped viruses (rhinovirus/enterovirus and adenovirus) were in constant circulation. Upon easing prevention measures, the detection rate remained above 60%, and an outbreak of an enveloped virus (RSV and parainfluenza virus) was noted. Compared with 2017-2019, the cyclical RSV epidemic was delayed, with a large surge in late 2020. CONCLUSIONS We observed a constant circulation of non-enveloped viruses when strict nonpharmaceutical interventions were employed and a delayed surge of enveloped viruses during the easing of restrictions. Continuous surveillance and monitoring of the evolutionary dynamics of respiratory viruses is important, while easing restrictions requires balanced judgment.

Abstract
PURPOSE In this study, we aimed to assess the geographic distribution and molecular characteristics of β-lactamases among Enterobacterales isolates causing intra-abdominal infections (IAIs) from 2015 to 2018 in the Asia-Pacific region. METHOD Isolates were investigated for extended-spectrum β-lactamases (ESBLs), AmpC β-lactamases, and carbapenemases using multiplex PCR assays and full-gene DNA sequencing. RESULT A total of 832 Enterobacterales isolates from 8 different countries with β-lactamase genes were analysed. Plasmid-mediated ESBLs and AmpC β-lactamases were encoded in 598 (71.9 %) and 314 (37.7 %) isolates, respectively. In 710 (85.3 %) carbapenemase-negative isolates, positivity for both AmpC β-lactamases and ESBLs was identified in 51 (8.5 %) Escherichia coli and 24 (3.4 %) Klebsiella pneumoniae isolates. The most prevalent countries were Taiwan and Vietnam, and the co-occurrence of CMY/CTX-M in E. coli and DHA-1/ESBLs in K. pneumoniae was predominant. All isolates showed high susceptibility to colistin, but susceptibility to carbapenems varied among different resistance mechanism combinations. Among 122 (14.7 %) isolates encoding carbapenemase, NDM (n = 67, including 64.2 % NDM-1) was the most common, followed by the OXA-48-type (n = 49), KPC (n = 24) and IMP (n = 4). The most prevalent country was Thailand (n = 44), followed by Vietnam (n = 35) and the Philippines (n = 21). Twenty-two isolates were found to encode multiple carbapenemases, 16 of which were collected from Thailand and harbored NDM-1, OXA-232 and CTX-M-15. Despite high susceptibility to amikacin, susceptibility to colistin was only 56 %. CONCLUSION The emergence of carbapenem-non-susceptible AmpC/ESBL co-occurring Enterobacterales and colistin non-susceptible carbapenemases co-occurring K. pneumoniae highlights potential therapeutic challenges in the Asia-Pacific region.

Abstract
BACKGROUND/PURPOSE This study aimed to investigate the in vitro susceptibilities of carbapenem-non-susceptible Pseudomonas aeruginosa (CNSPA) and Acinetobacter baumannii (CNSAB) isolates to cefiderocol, novel β-lactamase inhibitor (BLI) combinations, new tetracycline analogues, and other comparative antibiotics. METHODS In total, 405 non-duplicate bacteremic CNSPA (n = 150) and CNSAB (n = 255) isolates were collected from 16 hospitals in Taiwan between 2018 and 2020. Minimum inhibitory concentrations (MICs) were determined using the broth microdilution method, and susceptibilities were interpreted according to the relevant guidelines or in accordance with results of previous studies and non-species-related pharmacokinetic/pharmacodynamic data. RESULTS Among the isolates tested, cefiderocol demonstrated potent in vitro activity against CNSPA (MIC50/90, 0.25/1 mg/L; 100% of isolates were inhibited at ≤4 mg/L) and CNSAB (MIC50/90, 0.5/2 mg/L; 94.9% of isolates were inhibited at ≤4 mg/L) isolates. More than 80% of CNSPA isolates were susceptible to cefiderocol, ceftazidime/avibactam, ceftolozane/tazobactam, and amikacin, based on breakpoints established by the Clinical and Laboratory Standards Institute. Activities of new BLI combinations varied significantly. Tetracycline analogues, including tigecycline (MIC50/90, 1/2 mg/L; 92.5% of CNSAB isolates were inhibited at ≤2 mg/L) and eravacycline (MIC50/90, 0.5/1 mg/L; 99.6% of CNSAB isolates were inhibited at ≤2 mg/L) exhibited more potent in vitro activity against CNSAB than omadacycline (MIC50/90, 4/8 mg/L). CONCLUSIONS The spread of CNSPA and CNSAB poses a major challenge to global health. Significant resistance be developed even before a novel agent becomes commercially available. The development of on-site antimicrobial susceptibility tests for these novel agents is of great clinical importance.

Abstract
BACKGROUND COVID-19 vaccination is essential. However, no study has reported adverse events (AEs) after ChAdOx1 nCoV-19 vaccination in patients with end-stage renal disease (ESRD) on hemodialysis (HD). This study investigated the AEs within 30-days after the first dose of ChAdOx1 nCoV19 (Oxford-AstraZeneca) in ESRD patients on HD. METHODS AND FINDINGS A total of 270 ESRD patients on HD were enrolled in this study. To determine the significance of vascular access thrombosis (VAT) post vaccination, we performed a self-controlled case study (SCCS) analysis. Of these patients, 38.5% had local AEs; local pain (29.6%), tenderness (28.9%), and induration (15.6%) were the most common. Further, 62.2% had systemic AEs; fatigue (41.1%), feverishness (20%), and lethargy (19.9%) were the most common. In addition, post-vaccination thirst affected 18.9% of the participants with female predominance. Younger age, female sex, and diabetes mellitus were risk factors for AEs. Five patients had severe AEs, including fever (n = 1), herpes zoster (HZ) reactivation (n = 1), and acute VAT (n = 3). However, the SCCS analysis revealed no association between vaccination and VAT; the incidence rate ratio (IRR)-person ratio was 0.56 (95% CI 0.13-2.33) and 0.78 (95% CI 0.20-2.93) [IRR-event ratio 0.78 (95% CI 0.15-4.10) and 1.00 (95% CI 0.20-4.93)] in the 0-3 months and 3-6 months period prior to vaccination, respectively. CONCLUSIONS Though some ESRD patients on HD had local and systemic AEs after first-dose vaccination, the clinical significance of these symptoms was minor. Our study confirmed the safety profile of ChAdOx1 nCoV-19 in HD patients and presented a new viewpoint on vaccine-related AEs. The SCCS analysis did not find an elevated risk of VAT at 1 month following vaccination. Apart from VAT, other vaccine-related AEs, irrespective of local or systemic symptoms, had minor clinical significance on safety issues. Nonetheless, further coordinated, multi-center, or registry-based studies are needed to establish the causality.

Abstract
INTRODUCTION The clinical efficiency of cefoperazone/sulbactam (CPZ/SUL) against Escherichia coli bacteremia was unknown. This study aimed to explore the relationship between CPZ/SUL MIC values and clinical outcomes in Escherichia coli bacteremia. METHODS A multicenter, retrospective, observational cohort study was conducted in Taiwan between January 2015 and December 2020. Patients treated with CPZ/SUL for E. coli bacteremia were enrolled in the analysis. The CPZ/SUL MICs were determined by using the agar dilution method. The primary outcome was 30-day mortality. RESULTS Among 247 isolates, 160 (64.8%) isolates were susceptible, 8 (3.2%) were intermediate, and 79 (32.0%) were resistant to cefoperazone. The activity of cefoperazone against cefoperazone-non-susceptible E. coli (n = 87) was restored upon combination with sulbactam, with susceptibility ranging from 0% to 97.7%. The 30-day mortality was 4.5% (11/247) and overall clinical success rate was 91.9% (227/247). Multivariate Cox proportional-hazards model revealed that heart failure [adjusted relative risk (ARR), 5.49; 95% confidence interval (CI) 1.31-23.02; p = 0.020], malignancy (ARR 7.50; 95% CI 2.02-27.80; p = 0.003), SOFA score (ARR 1.29; 95% CI 1.09-1.52; p = 0.003), and CPZ/SUL MIC ≥ 64 mg/L (ARR 11.31; 95% CI 1.34-95.52; p = 0.026) were independently associated with 30-day mortality. No statistically significant differences in 30-day mortality were found between groups with or without cefoperazone susceptibility (3.4% vs. 5.0%, p = 0.751, respectively). CONCLUSIONS Patients with E. coli bacteremia who were treated with CPZ/SUL had a favorable outcome when the MICs of the isolates were ≤ 16 mg/L and a high risk of mortality with MICs ≥ 64 mg/L.

Abstract
Candida auris, a multidrug resistant pathogenic yeast, has spread worldwide and caused several outbreaks in healthcare settings. Here, we report the first case of C. auris candidemia in Taiwan in a patient with a two-month history of hospitalization in Vietnam. We performed further investigation on the isolate from the present case as well as the previously reported C. auris isolate identified from a wound in 2018 in Taiwan, which was the first case reported in Taiwan. Both C. auris isolates were found to be susceptible to fluconazole, amphotericin B, and echinocandins. Additionally, mutations in ERG11 or FKS1 were not detected in either isolate. Microsatellite genotyping revealed that both isolates belonged to the South Asian clade. In recent years, C. auris has emerged as a global concern, and differences in clades and susceptibility patterns mandate further awareness and systematic surveillance.

Abstract
This study aimed to compare clinical outcomes and adverse effects in septic patients with impaired renal function who received different dosages of cefoperazone–sulbactam (CFP–SUL 1 g/1 g or 2 g/2 g every 12 h). The retrospective study was conducted using the Chang Gung Research Database to include adult patients who had renal insufficiency presented with septicemia caused by Gram-negative organisms and had received CFP–SUL for more than 1 week. A total of 265 patients (44 in the CFP–SUL 1 g/1 g group and 221 in the CFP–SUL 2 g/2 g group) were eligible to be included in this study. After 1:3 propensity score matching, 41 and 123 patients in the CFP–SUL 1 g/1 g and CFP–SUL 2 g/2 g groups, respectively, were included for analyses. There were no significant between-group differences in all-cause mortality rates and adverse effects, including prolonged prothrombin time. A logistic regression model showed that the Pitt bacteremia score was related to all-cause mortality rate and prolonged prothrombin time was associated with renal replacement therapy. The adverse effects of CFP–SUL did not increase in septic patients with impaired renal function receiving CFP–SUL 2 g/2 g Q12H. However, this study may be underpowered to reveal a difference in all-cause mortality.

Abstract
BACKGROUND Hepatitis C virus (HCV) genotype 6 (HCV-6) infection is prevalent predominantly in Southeast Asia, and the data on the virologic response of HCV-6 to direct-acting antivirals (DAAs) are sparse in people living with human immunodeficiency virus (HIV) (PLWH).
AIM To assess the virologic response of HCV-6 to DAAs in PLWH.
METHODS From September 2016 to July 2019, PLWH coinfected with HCV-6 initiating DAAs were included. Laboratory investigations were performed at baseline, the end of treatment, and 12 wk off-therapy.
RESULTS Of the 349 PLWH included (mean age 48.9 years, 82.5% men), 80.5% comprised people who inject drugs, 18.1% men who have sex with men, and 1.4% heterosexuals. Coexistent hepatitis B virus infection was present in 12.3% of the included PLWH, liver cirrhosis 10.9%, hepatocellular carcinoma 0.9%, and previous HCV treatment experience 10.9%. The mean baseline plasma HCV RNA was 6.2 log10 IU/mL. Treatment with glecaprevir/pibrentasvir was initiated in 51.9%, sofosbuvir/ledipasvir 41.5%, sofosbuvir/velpatasvir 6.3%, and sofosbuvir/daclatasvir 0.3%. At DAA initiation, antiretroviral therapy containing tenofovir alafenamide was given in 26.4%, tenofovir disoproxil fumarate 34.4%, non-tenofovir alafenamide/tenofovir disoproxil fumarate 39.3%, non-nucleoside reverse-transcriptase inhibitors 30.4%, protease inhibitors 4.0%, and integrase strand transfer inhibitors 66.8%; 94.8% of the included patients had CD4 counts ≥ 200 cells/mm3 and 96.0% had plasma HIV RNA < 50 copies/mL. Overall, 96.8% achieved undetectable plasma HCV RNA (< 30 IU/mL) at end of treatment; and 92.3% achieved sustained virologic response 12 wk off-therapy in the intention-to-treat analysis (93.5% in patients receiving sofosbuvir-based DAAs and 91.2% in those receiving glecaprevir/pibrentasvir).
CONCLUSION Similar to the observation made in HIV-negative patients, sustained virologic response 12 wk off-therapy with DAAs is high in PLWH coinfected with HCV-6.

Abstract
The outbreak of COVID-19 has significantly changed the epidemiology of respiratory tract infection in several ways. The implementation of non-pharmaceutical interventions (NPIs) including universal masking, hand hygiene, and social distancing not only resulted in a decline in reported SARS-CoV-2 cases but also contributed to the decline in the non-COVID-19 respiratory tract infection-related hospital utilization. Moreover, it also led to the decreased incidence of previous commonly encountered respiratory pathogens, such as influenza and Streptococcus pneumoniae. Although antimicrobial agents are essential for treating patients with COVID-19 co-infection, the prescribing of antibiotics was significantly higher than the estimated prevalence of bacterial co-infection, which indicated the overuse of antibiotics or unnecessary antibiotic use during the COVID-19 pandemic. Furthermore, inappropriate antimicrobial exposure may drive the selection of drug-resistant microorganisms, and the disruption of infection control in COVID-19 setting measures may result in the spread of multidrug-resistant organisms (MDROs). In conclusion, NPIs could be effective in preventing respiratory tract infection and changing the microbiologic distribution of respiratory pathogens; however, we should continue with epidemiological surveillance to establish updated information, antimicrobial stewardship programs for appropriate use of antibiotic, and infection control prevention interventions to prevent the spread of MDROs during the COVID-19 pandemic.

Abstract
Shigellosis appears to increase in certain at-risk populations in developed countries. Based on the nationwide surveillance, the annual incidence of shigellosis in Taiwan (1999-2019) was 0.38-5.77 cases per 100,000 people. Indigenous shigellosis has mostly affected men who have sex with men (MSM) and people living with HIV (PLWH) since 2015. In this retrospective study, compared with those diagnosed before 2015, indigenous cases diagnosed during 2015-2019 mostly occurred in male adults (96.0% vs 47.1%, P < 0.001), with a longer hospital stay (median 5.0 vs 3.5 days, P = 0.029) and different coinfections. The predominant strains in 2015 and 2016 were ciprofloxacin-resistant Shigella sonnei and azithromycin non-susceptible Shigella flexneri (S. flexneri) 3a, which had been replaced by ciprofloxacin-resistant S. flexneri 2a since 2018. Notably, six indigenous cases were caused by cefotaxime-resistant S. flexneri. Inappropriate use of empiric antibiotic treatment was common. In conclusion, there is an ongoing spread of ciprofloxacin-resistant shigellosis among PLWH and MSM and cefotaxime-resistant S. flexneri is an emerging threat in Taiwan.

Abstract
We report 4 cases of neonatal sepsis caused by Streptococcus gallolyticus. The clinical course was quite similar to early-and late-onset group B streptococcus disease. None of the mothers had group B streptococcus (GBS) colonization on prenatal screening nor received intrapartum antibiotics. We proposed the sporadic distribution of S. gallolyticus sepsis among neonates was partly due to relatively low colonization rate in adults compared with GBS. Species determination of S. gallolyticus may not be available using conventional microbiological methods and may contribute to underestimation or misclassification. In our series, we highlighted the importance of S. gallolyticus as an important pathogen in neonatal sepsis deserving further surveillance.

Abstract
The aim of this study was to use a network meta-analysis (NWA) to evaluate the relative efficacy and safety of various neuraminidase inhibitors (NAIs) in reducing the duration of influenza symptoms, and thereby, informing the selection of suitable therapeutic regimens for patients with influenza. We conducted a systematic review of randomized controlled trials comparing the clinical effects of four NAIs administered to patients with influenza and placebo. Relevant studies were found in the PubMed and Cochrane databases. Unpublished studies were collected from the ClinicalTrials.gov registry and through hand searching. We carried out NWA to compare the different regimens with each other and across subgroups of age and medical status (high-risk patients). A total of 58 two-arm studies were identified. Five regimens were efficacious in reducing the time to alleviation of influenza symptoms in all populations; this efficacy was comparable. No significant improvements were seen in combination therapy groups. The mean difference in the time to alleviation of symptoms ranged from 12.78 to 19.51 h. According to the summarized mean difference and surface under the cumulative ranking curve (SUCRA), peramivir (SUCRA = 82.6%), zanamivir (SUCRA = 64%), and oseltamivir (SUCRA = 55.1%) were the three top-ranking drugs for treating influenza. Zanamivir and peramivir were the preferred pharmacologic intervention among all investigated interventions based on the calculated "value preference of SUCRA." This study is a network meta-analysis to explore the therapeutic effects of NAIs in patients with influenza. Peramivir might be the best choice for reducing the time to alleviation of symptoms.

This systematic review and meta-analysis of randomized controlled trials (RCTs) compared the clinical efficacy and safety of anti-MRSA cephalosporin and vancomycin-based treatment in treating acute bacterial skin and skin structure infections (ABSSSIs). PubMed, Embase, Cochrane Central Register of Controlled Trials, Turning Research into Practice, and ClinicalTrials.gov databases were searched for relevant articles from inception to 15 June 2020. RCTs comparing the clinical efficacy and safety of anti-MRSA cephalosporin with those of vancomycin-based regimens in treating adult patients with ABSSSIs were included. The primary and secondary outcomes were clinical response at the test-of-cure assessments and risk of adverse events (AEs), respectively. Eight RCTs were enrolled. The clinical response rate was not significantly different between anti-MRSA cephalosporin and vancomycin-based treatments (odds ratio [OR], 1.05; 95% CI, 0.90–1.23; I2 = 0%). Except for major cutaneous abscesses in which anti-MRSA cephalosporin-based treatment was associated with a lower clinical response rate than vancomycin-based treatment (OR, 0.62; 95% CI, 0.40–0.97; I2 = 0%), other subgroup analyses according to the type of cephalosporin (ceftaroline or ceftobiprole), type of infection, and different pathogens did not show significant differences in clinical response. Anti-MRSA cephalosporin-based treatment was only associated with a higher risk of nausea than vancomycin-based treatment (OR, 1.41; 95% CI, 1.07–1.85; I2 = 0%). In treating ABSSSIs, the clinical efficacy of anti-MRSA cephalosporin is comparable to that of vancomycin-based treatment, except in major cutaneous abscesses. In addition to nausea, anti-MRSA cephalosporin was as tolerable as vancomycin-based treatment.

Abstract
OBJECTIVES To investigate the in vitro activity of antibiotics against clinical Elizabethkingia anophelis isolates and to find a suitable antibiotic combination with synergistic effects to combat antibiotic-resistant E. anophelis and its associated biofilm. METHODS E. anophelis isolates were identified by 16S rRNA sequencing; 30 strains with different pulsotypes were identified and the MIC, antibiotic resistance mechanism, antibiotic combination activity and killing effects of antimicrobial agents on biofilms of these strains were determined. RESULTS All E. anophelis isolates were susceptible to minocycline and cefoperazone/sulbactam (1:1). More than 90% of clinical isolates were susceptible to cefoperazone/sulbactam (1:0.5), piperacillin/tazobactam and rifampicin. Some novel mutations, such as gyrA G81D, parE D585N and parC P134T, that have never been reported before, were identified. The synergistic effect was most prominent for the combination of minocycline and rifampicin, with 93.3% of their FIC index values ≤0.5, and no antagonism was observed using the chequerboard method. This synergistic effect between minocycline and rifampicin was also observed using time-killing methods for clinical E. anophelis isolates at both normal inoculum and high inoculum. Twenty-nine isolates tested positive for biofilm formation. Minocycline remained active against biofilm-embedded and biofilm-released planktonic E. anophelis cells; however, the enhanced effect of minocycline by adding rifampicin was only observed at 24 h (not at 72 and 120 h). CONCLUSIONS Although E. anophelis was resistant to many antibiotics and could exhibit biofilm formation, minocycline showed potent in vitro activity against this pathogen and its associated biofilm.

Abstract
OBJECTIVES Real-world experience regarding the effectiveness of co-formulated elvitegravir, cobicistat, emtricitabine and tenofovir alafenamide (EVG/C/FTC/TAF) as a switch regimen is sparse among people living with HIV (PLWH) harbouring the M184V/I mutation with or without thymidine analogue-associated mutations (TAMs). METHODS In this retrospective multicentre study, PLWH who were switched to EVG/C/FTC/TAF after having achieved viral suppression (plasma HIV RNA <200 copies/mL) for 6 months or longer were included. Patients with archived M184V/I mutation (case patients) were matched to controls without M184V/I mutation at a 1:4 ratio. Patients with a history of virological failure or resistance to elvitegravir were excluded. The primary endpoint was virological non-success (plasma HIV RNA ≥50 copies/mL) at Week 48 of switch using a modified FDA snapshot analysis. RESULTS Overall, 100 case patients with the M184V/I mutation were identified, including 6 (6.0%) with K65R and 13 (13.0%) with at least one TAM, and were matched to 400 controls in terms of gender, age (mean = 40.3 versus 39.7 years) and cumulative exposure duration to tenofovir disoproxil fumarate (median = 146 versus 143 weeks). At Week 48, the rate of virological non-success for the case patients and controls was 5.0% (5/100) and 3.3% (13/400), respectively (difference = 1.7%; 95% CI = -2.9%-6.3%), while the rate of virological success was 88.0% and 89.5% for the case patients and controls, respectively. The presence of the K65R mutation or TAMs was not associated with virological non-response. CONCLUSIONS Among virally suppressed PLWH, EVG/C/FTC/TAF is effective in maintaining viral suppression at Week 48 despite archived M184V/I mutation with or without TAMs.

Abstract
This study examined the susceptibility of carbapenem-nonsusceptible Enterobacterales (CNSE) to cefiderocol, cefepime/zidebactam, cefepime/enmetazobactam, omadacycline, eravacycline and other comparative agents. Non-duplicate Enterobacterales isolates from 16 Taiwanese hospitals were evaluated. Minimum inhibitory concentrations (MICs) were determined using the broth microdilution method, and susceptibility results were interpreted based on relevant guidelines. In total, 201 CNSE isolates were investigated, including 26 Escherichia coli isolates and 175 Klebsiella pneumoniae isolates. Carbapenemase genes were detected in 15.4% (n=4) of E. coli isolates and 47.4% (n=83) of K. pneumoniae isolates, with the most common being blaKPC (79.3%, 69/87), followed by blaOXA-48-like (13.8%, 12/87). Cefiderocol was the most active agent against CNSE; only 3.8% (n=1) of E. coli isolates and 4.6% (n=8) of K. pneumoniae isolates were not susceptible to cefiderocol. Among the carbapenem-resistant E. coli and K. pneumoniae isolates, 88.5% (n=23) and 93.7% (n=164), respectively, were susceptible to ceftazidime/avibactam. For cefepime/zidebactam, 23 (88.5%) E. coli isolates and 155 (88.6%) K. pneumoniae isolates had MICs ≤2/2 mg/L. For cefepime/enmetazobactam, 22 (84.6%) E. coli isolates and 85 (48.6%) K. pneumoniae isolates had MICs ≤2/8 mg/L. The higher MICs of K. pneumoniae against cefepime/enmetazobactam were due to only one (1.5%) of the 67 blaKPC-carrying isolates being susceptible. MICs of omadacycline were significantly higher than those of eravacycline and tigecycline. In summary, cefiderocol, ceftazidime/avibactam and cefepime/zidebactam were more effective against carbapenem-nonsusceptible E. coli and K. pneumoniae than other drugs, highlighting their potential as valuable therapeutics.

Abstract
BACKGROUND Atherosclerosis and vascular inflammatory response have been considered as risk factors for non-typhoidal Salmonella (NTS) vascular infection. The study aims to assess the risk of vascular infection by measuring atherosclerosis severity, NTS vascular infection (NTSVI) score, and serum levels of inflammatory markers in people with NTS bacteremia. METHODS A prospective observational study was conducted in two medical centers and two regional hospitals. Adults aged ≥50 years with NTS bacteremia who underwent computed tomography (CT) scan for revealing vascular infections were enrolled. The degree of atherosclerosis was scaled by a calcium score determined by a CT scan. Serum concentrations of inflammatory biomarkers were determined in the patients enrolled in a medical center. RESULTS Fourteen (20.3%) of 69 patients with NTS bacteremia had vascular infections. Calcium scores over the thoracic (12,540 vs. 3,261, P = 0.0005) and abdominal (9755 vs. 3,461, P = 0.0006) aorta of those with vascular infections were higher than those without vascular infection. All vascular infections were present in the high-risk group (NTSVI score ≥1), yielding a sensitivity of 100% and specificity of 30.9%. Among 17 low-risk patients (NTSVI score <1), none had vascular infections, resulting in a negative predictive value of 100%. Higher plasma concentrations of IL-1β were detected in the cases of vascular infection than those in the control group (23.6 vs. 1.06 pg/mL, P = 0.001). CONCLUSION Atherosclerosis of the aorta which is associated with a positive NTSVI score can predict the occurrence of vascular infections and serum IL-1β could be a biomarker for vascular infection in patients with NTS bacteremia.

Abstract
BACKGROUND/PURPOSE Streptococcus pneumoniae causes pneumonia and other invasive diseases, and is a leading cause of mortality in the elderly population. The present study aimed to provide current antimicrobial resistance and epidemiological profiles of S. pneumoniae infections in Taiwan. METHODS A total of 252 nonduplicate S. pneumoniae isolates were collected from patients admitted to 16 hospitals in Taiwan between January 2017 and December 2019, and were analyzed. The minimum inhibitory concentration of antibiotics was determined using the Vitek 2 automated system for antimicrobial susceptibility testing. Furthermore, epidemiological profiles of S. pneumoniae infections were analyzed. RESULTS Among the strains analyzed, 88% were recognized as invasive pneumococcal strains. According to the Clinical and Laboratory Standards Institute criteria for non-meningitis, the prevalence of penicillin-non-susceptible S. pneumoniae demonstrated a declining trend from 43.6% in 2017 to 17.2% in 2019. However, the rate of penicillin-non-susceptible S. pneumoniae was 85.7% based on the criteria for meningitis. Furthermore, the prevalence of ceftriaxone-non-susceptible S. pneumoniae was 62.7% based on the criteria for meningitis. Isolates demonstrated higher susceptibility toward doripenem and ertapenem than toward meropenem and imipenem. An increased rate of non-susceptibility toward levofloxacin was observed in southern Taiwan (15.1%) and elderly patients (≥65 years; 11.4%). Most isolates were susceptible to vancomycin and linezolid. CONCLUSION Empirical treatment with ceftriaxone monotherapy for pneumococcal meningitis should be carefully monitored owing to its high non-susceptibility rate. The susceptibility rates of most isolates to penicillin (used for treating non-meningitis pneumococcal diseases), carbapenems (ertapenem and doripenem), respiratory quinolones (moxifloxacin and levofloxacin), vancomycin, and linezolid suggested the potential of these antibiotics in treating pneumococcal diseases in Taiwan.

Abstract
BACKGROUND The efficacy and safety of switching from tenofovir disoproxil fumarate-based antiretroviral therapy to coformulated elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide (E/C/F/TAF) has not been widely investigated in HIV/hepatitis B virus (HBV)-coinfected Asian population. METHODS Between February and October 2018, HIV/HBV-coinfected patients who had achieved HIV viral suppression with tenofovir disoproxil fumarate-containing regimens were switched to E/C/F/TAF. Assessments of plasma HBV and HIV viral load, HBV serology, renal function, lipid profiles, and bone mineral density (BMD) were performed at weeks 24 and 48 after switch. RESULTS A total of 274 HIV/HBV-coinfected participants were enrolled, with 12.8% testing HBeAg-positive and 94.2% having plasma HBV DNA <20 IU/mL at baseline. At weeks 24 and 48, 92.7% and 89.8% achieved plasma HBV DNA <20 IU/mL; 4.7% and 5.1% had HBV DNA ≥20 IU/mL; and 2.6% and 5.1% had no data, respectively. At weeks 24 and 48, 95.6% and 94.2% of participants maintained HIV RNA <50 copies/mL, respectively. Compared with baseline, the median urine β2-microglobulin-to-creatinine ratio at week 48 decreased significantly from 165 to 90 μg/g (P < 0.001). The mean BMD of the spine and hip improved at week 48 (+1.77% and +1.33%, respectively). Significantly higher lipid profiles were observed after switch to E/C/F/TAF. Thirteen (4.7%) patients withdrew from the study before week 48, with 7 (2.6%) patients because of adverse effects. CONCLUSIONS Switch to E/C/F/TAF maintained HBV and HIV viral suppression and resulted in the improvement of proteinuria and BMD of the spine and hip but increased lipid levels in HIV/HBV-coinfected patients at week 48.

Abstract
INTRODUCTION While coformulated ledipasvir (90 mg)/sofosbuvir (400 mg) (LDV/SOF) is approved for the treatment of hepatitis C virus (HCV) genotype 2 (GT2) infection in Taiwan, Japan, and New Zealand, data regarding its use for HIV (Human Immunodeficiency Virus)-positive patients infected with HCV GT2 are sparse. We aimed to assess the effectiveness and tolerability of LDV/SOF for HIV-positive patients with HCV GT2 coinfection. METHODS From January 2019 to July 2020, consecutive HIV-positive Taiwanese patients infected with HCV GT2 who received LDV/SOF were retrospectively included for analysis. The effectiveness was determined by sustained virologic response 12 weeks off-therapy (SVR12). RESULTS Of the 114 patients (mean age, 38.6 years) initiating LDV/SOF during the study period, 0.9% had liver cirrhosis and 4.4% were HCV treatment-experienced. All patients had estimated glomerular filtration rate (eGFR) > 30 ml/min/1.73 m2 and were receiving antiretroviral therapy with 98.2% having CD4 counts ≥ 200 cells/mm3 and 93.9% plasma HIV RNA load < 50 copies/ml. Antiretrovirals prescribed included tenofovir alafenamide/emtricitabine in 42.1%, tenofovir disoproxil fumarate (TDF)/emtricitabine 18.4%, other nucleoside reverse transcriptase inhibitors (NRTIs) 39.5%, non-NRTIs 12.3%, protease inhibitors 13.2%, and integrase inhibitors 74.6%. All patients had undetectable plasma HCV RNA load at the end of treatment, and 96.5% achieved SVR12 in intention-to-treat analysis. The on-treatment eGFR decline was more pronounced in those receiving TDF-containing antiretroviral therapy (mean change, - 8.33 ml/min/1.73 m2), which was reversible after discontinuation of LDV/SOF. None of the patients interrupted LDV/SOF during the 12-week treatment course. CONCLUSION Similar to the response observed among HIV-negative patients, LDV/SOF is effective for HIV-positive patients coinfected with HCV GT2.

Abstract
Objective: To analyze the distribution characteristics of new pneumoconiosis in different industries in Tianjin from 2009 to 2018, in order to provide a theoretical basis for the prevention and treatment of pneumoconiosis. Methods: In November 2019, the data of new pneumoconiosis cases in Tianjin from 2009 to 2018 were collected and classified according to difference industries. The epidemiological characteristics of new pneumoconiosis in different industries were analyzed based on time, type of pneumoconiosis, type of work, age, and working age. Results: A total of 4657 new cases of pneumoconiosis were reported in Tianjin from 2009 to 2018, 4640 cases (99.63%) in the first stage, 13 cases (0.28%) in the second stage, and 4 case (0.09%) in the third stage. The number of new cases increased with time and then decreased. Among them, there were 3482 males (74.77%) and 1175 females (25.23%) . The proportion of women with new pneumoconiosis in the non-metallic mineral products industry was the highest, and the differences were statistically significant (P<0.05) . There are differences in the distribution of new pneumoconiosis species in different industries (χ(2)=4920.11, P<0.05) . Silicosis is mainly distributed in non-metallic mineral products industry, metal smelting and rolling processing industry, petroleum processing coking and nuclear fuel processing industries. Foundry worker's pneumoconiosis is mainly distributed in the general equipment manufacturing industry and special equipment manufacturing industry, and cement pneumoconiosis is mainly distributed in the non-metallic mineral products industry. The types of work are mainly distributed in smelting, casting, raw materials and forming workers, and the sum of the three accounts for 36.46% (1689/4657) . The M (P(25), P(75)) of diagnosis age was 56.0 (50.0, 63.0) years, and the M (P(25), P(75)) of working age was 19.0 (16.0, 26.0) years. The working age of new pneumoconiosis patients in the petroleum processing, coking and nuclear fuel processing industries is 19.0 (16.0, 26.0) years, which is shorter than that of other industries (P<0.05) ; The diagnostic age of the general equipment manufacturing industry is 54.0 (49.0, 59.0) years, which is less than that of other industries (P<0.05) . New pneumoconiosis is mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in non-metallic mineral products industry, metal smelting, calendar processing industry and general equipment manufacturing industry are mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in the metal products industry, special equipment manufacturing industry and petroleum processing, coking and nuclear fuel processing industries are mainly distributed in large enterprises. Conclusion: The work of preventing and controlling pneumoconiosis in Tianjin has a long way to go. We should implement targeted measures according to the characteristics of pneumoconiosis industry, strengthen the supervision of hazard industries, and effectively control the occurrence of pneumoconiosis.

Abstract
BACKGROUND/PURPOSE Accurate identification of Candida species is increasingly important in the era of emergence of Candida auris. We aimed to compare the identification performance of two matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) systems (Vitek MS and Bruker biotyper MS) and an oligonucleotide array for uncommon blood yeast isolates and demonstrate the susceptibilities among those isolates. METHOD Candida species isolates from blood culture other than Candida albicans, Candida parapsilosis, Candida tropicalis, Candida glabrata, and Candida krusei identified by biochemical methods were collected from multiple hospitals and further identified by an oligonucleotide array based on the internal transcribed spacer-1 (ITS-1) and ITS-2 sequences of the rRNA genes, Vitek MS and Bruker biotyper MS. The minimal inhibitory concentrations (MICs) of these clinical isolates were determined by the Sensititre YeastOne (SYO) system. RESULTS Among 136 isolates, Candida guilliermondii was most common (52, 38.2%), followed by C. lusitaniae (13, 9.6%) and C. haemulonii (12, 8.8%). The oligonucleotide array, Vitek MS and Bruker biotyper MS correctly identified 89.7% (122), 90.4% (123), and 92.6% (126) of these isolates, respectively. Elevated minimal inhibitory concentrations (MICs) of fluconazole were observed for C. haemulonii (MIC90: 256 mg/L), and C. guilliermondii (MIC90: 16 mg/L) with 28.4% of uncommon Candida isolates with MIC ≧ 8 mg/L. CONCLUSIONS For uncommon Candida species, the unmet need for current databases of two commercial MALDI-TOF MS systems is highlighted, and the oligonucleotide array may serve as a supplement.

Abstract
Aeromonas dhakensis is an emerging human pathogen which causes fast and severe infections worldwide. Under the gradual pressure of lacking useful antibiotics, finding a new strategy against A. dhakensis infection is urgent. To understand its pathogenesis, we created an A. dhakensis AAK1 mini-Tn10 transposon library to study the mechanism of A. dhakensis infection. By using a Caenorhabditis elegans model, we established a screening platform for the purpose of identifying attenuated mutants. The uvrY mutant, which conferred the most attenuated toxicity toward C. elegans, was identified. The uvrY mutant was also less virulent in C2C12 fibroblast and mice models, in line with in vitro results. To further elucidate the mechanism of UvrY in controlling the toxicity in A. dhakensis, we conducted a transcriptomic analysis. The RNAseq results showed that the expression of a unique hemolysin ahh1 and other virulence factors were regulated by UvrY. Complementation of Ahh1, one of the most important virulence factors, rescued the pore-formation phenotype of uvrY mutant in C. elegans; however, complementation of ahh1 endogenous promoter-driven ahh1 could not produce Ahh1 and rescue the virulence in the uvrY mutant. These findings suggest that UvrY is required for the expression of Ahh1 in A. dhakensis. Taken together, our results suggested that UvrY controls several different virulence factors and is required for the full virulence of A. dhakensis. The two-component regulator UvrY therefore a potential therapeutic target which is worthy of further study.
