    Title translation For a co-construction of the health care provision.
    Abstract The deployment of quality approaches in hospitals and the evolution of the place of users in the health care system is resulting in patients becoming more involved in the quality of care. Taking into consideration the contribution of collaborative practices is necessary in order to enable patients and caregivers to work together effectively, and to improve the quality of care. Finally, the recognition of patients' expertise and the implementation of adapted methods allow different points of view to come together and decisions to be made jointly.

    Abstract Objectives: The occurrence of metallo-beta-lactamase-producing Pseudomonas aeruginosa (MBL-PA) isolates is increasing globally, including in Switzerland. The aim of this study was to characterise, phenotypically and genotypically, the MBL-PA isolates submitted to the Swiss National Reference Center for Emerging Antibiotic Resistance (NARA) reference laboratory over a 12-month period from July 2022 to July 2023.
    Methods: Thirty-nine non-duplicate MBL-PA Isolates were submitted to NARA over the study period from across Switzerland. Susceptibility was determined by broth microdilution according to EUCAST methodology. Whole-genome sequencing was performed on 34 isolates. Sequence types (STs) and resistance genes were ascertained using the Centre for Genomic Epidemiology platform. MBL genes, bla
    Results: The most prevalent MBL types identified in this study were VIM (21/39; 53.8%) followed by NDM (11/39; 28.2%), IMP (6/39; 15.4%), and a single isolate produced both VIM and NDM enzymes. WGS identified 13 different STs types among the 39 isolates. They all exhibited resistance to cephalosporins, carbapenems, and the beta-lactam-beta-lactamase inhibitor combinations, ceftolozane-tazobactam, ceftazidime-avibactam, imipenem-relebactam, and meropenem-vaborbactam, and 8 isolates were cefiderocol (FDC) resistant. Recombinant P. aeruginosa strains producing bla
    Conclusions: This study showed that the MBL-PA in Switzerland could be attributed to the wide dissemination of high-risk clones that accounted for most isolates in this study. Although FDC resistance was only found in 8 isolates, MBL carriage was shown to be a major contributor to this phenotype.

    Abstract Objectives: A novel ß-lactam-β-lactamase inhibitor (BLBI), meropenem (MEM), combined with the boronate-based inhibitor vaborbactam (VAB), has recently been introduced for the treatment of infections caused by Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacterales. The purpose of this study was to select for MEM-VAB resistance using a collection of eight KPC-producing K. pneumoniae clinical isolates, including three that produce KPC variants conferring ceftazidime-avibactam (CAZ-AVI) resistance, and subsequently decipher the corresponding resistance mechanisms.
    Methods: Mutants were selected in a stepwise process on agar plates containing different MEM-VAB concentrations. Susceptibility testing was performed by broth microdilution, and complementation assays were performed with wildtype ompK36. Whole genome sequencing was performed on mutants, and KPC copy number was assessed by quantitative polymerase chain reaction .
    Results: Mutants were obtained from 6/8 tested isolates and reduced susceptibility to all tested β-lactams, and BLBIs, including CAZ-AVI, imipenem-relebactam, and aztreonam-AVI, were observed. No mutations were identified in the bla
    Conclusions: In contrast to what is observed with KPC-producing mutants exhibiting resistance to CAZ-AVI, mainly corresponding to mutated KPC enzymes, here the MEM-VAB-resistant mutants showed permeability defects combined with increased KPC production, resulting from genomic rearrangement.

    Abstract Carbapenemase-producing in Enterobacterales (CPE) represent a critical health concern worldwide, including in Switzerland, leading to very limited therapeutic options. Therefore, our aim was to evaluate the susceptibility to the novel ß-lactam/ß-lactamase inhibitor combinations ceftazidime-avibactam, meropenem-vaborbactam, and imipenem-relebactam of CPE isolates recovered in Switzerland from 2018 to 2020. A total of 150 clinical CPE were studied including mainly Klebsiella pneumoniae (n = 61, 40.3%) and Escherichia coli (n = 53, 35.3%). The distribution of carbapenemases was as follows: KPC-like (32%), OXA-48-like (32%), NDM-like (24%), combinations of carbapenemases (10%), VIM-1 producers (n = 2), and a single IMI-1 producer. Overall, 77% of the strains were susceptible to meropenem-vaborbactam, 63% was susceptible to ceftazidime-avibactam, and 62% susceptible to imipenem-relebactam. Those data may contribute to optimize the choice of first line therapy for treating infections due to CPE.

    Abstract Background: Aztreonam/avibactam is one of the last therapeutic options for treating infections caused by NDM-like-producing Enterobacterales. However, PBP3-modified and NDM-producing Escherichia coli strains that co-produce CMY-42 have been shown to be resistant to this drug combination. The aim of our study was to assess the in vitro activity of cefepime/taniborbactam and cefepime/zidebactam against such aztreonam/avibactam-resistant E. coli strains.
    Methods: MIC values of aztreonam, aztreonam/avibactam, cefepime, cefepime/taniborbactam, cefepime/zidebactam and zidebactam alone were determined for 28 clinical aztreonam/avibactam-resistant E. coli isolates. Those isolates produced either NDM-5 (n = 24), NDM-4 (n = 2) or NDM-1 (n = 2), and they all co-produced CMY-42 (n = 28). They all harboured a four amino acid insertion in PBP-3 (Tyr-Arg-Ile-Asn or Tyr-Arg-Ile-Lys).
    Results: All strains were resistant to aztreonam/avibactam and cefepime, as expected. The resistance rate to cefepime/taniborbactam was 100%, with MIC50 and MIC90 being at 16 mg/L and 64 mg/L, respectively. Conversely, all strains were susceptible to cefepime/zidebactam, with both MIC50 and MIC90 at 0.25 mg/L. Notably, all strains showed low MICs for zidebactam alone, with MIC50 and MIC90 at 0.5 mg/L and 1 mg/L.
    Conclusions: Our data highlighted the excellent in vitro performance of the newly developed β-lactam/β-lactamase inhibitor combination cefepime/zidebactam against aztreonam/avibactam-resistant E. coli strains, suggesting that this combination could be considered as an efficient therapeutic option in this context. Our study also highlights the cross-resistance between acquired resistance to aztreonam/avibactam and the cefepime/taniborbactam combination.

    Abstract Purpose: To evaluate the different present and future therapeutic β-lactam/β-lactamase inhibitor (BL/BLI) alternatives, namely aztreonam-avibactam, imipenem-relebactam, meropenem-vaborbactam, cefepime-zidebactam, cefepime-taniborbactam, meropenem-nacubactam, and sulbactam-durlobactam against clinical isolates showing reduced susceptibility or resistance to cefiderocol in Enterobacterales, Acinetobacter baumannii, and Pseudomonas aeruginosa.
    Methods: MIC values of aztreonam, aztreonam-avibactam, cefepime, cefepime-taniborbactam, cefepime-zidebactam, imipenem, imipenem-relebactam, meropenem, meropenem-vaborbactam, meropenem-nacubactam, sulbactam-durlobactam, and cefiderocol combined with a BLI were determined for 67, 9, and 11 clinical Enterobacterales, P. aeruginosa or A. baumannii isolates, respectively, showing MIC values of cefiderocol being ≥1 mg/L. If unavailable, the respective β-lactam breakpoints according to EUCAST were used for BL/BLI combinations.
    Results: For Enterobacterales, the susceptibility rates for aztreonam, cefepime, imipenem, and meropenem were 7.5%, 0%, 10.4%, and 10.4%, respectively, while they were much higher for cefepime-zidebactam (91%), cefiderocol-zidebactam (91%), meropenem-nacubactam (71.6%), cefiderocol-nacubactam (74.6%), and cefiderocol-taniborbactam (76.1%), as expected. For P. aeruginosa isolates, the higher susceptibility rates were observed for imipenem-relebactam, cefiderocol-zidebactam, and meropenem-vaborbactam (56% for all combinations). For A. baumannii isolates, lower susceptibility rates were observed with commercially or under development BL/BLI combos; however, a high susceptibility rate (70%) was found for sulbactam-durlobactam and when cefiderocol was associated to some BLIs.
    Conclusions: Zidebactam- and nacubactam-containing combinations showed a significant in vitro activity against multidrug-resistant Enterobacterales clinical isolates with reduced susceptibility to cefiderocol. On the other hand, imipenem-relebactam and meropenem-vaborbactam showed the highest susceptibility rates against P. aeruginosa isolates. Finally, sulbactam-durlobactam and cefiderocol combined with a BLI were the only effective options against A. baumannii tested isolates.
