Mortality predictors and definition proposal for complicated coagulase-negative Staphylococcus bacteremia. A multicenter prospective cohort study.

Objective: To explore a definition for complicated coagulase-negative staphylococci bloodstream infections (CoNS BSI), and to identify predictors for mortality.

Methods: Prospective cohort study conducted from October 2016 to March 2017 in 26 Spanish hospitals. Complicated CoNS BSI criteria included lack of early catheter removal in catheter-related cases, foreign indwelling implant, persistent bacteremia, fever ≥72 hours on active therapy, metastatic infection or deep-seated focus and infective endocarditis.

Genomic virulence markers are associated with severe outcomes in patients with Pseudomonas aeruginosa bloodstream infection.

Background: Pseudomonas aeruginosa (PA) bloodstream infection (BSI) is a common healthcare-associated complication linked to antimicrobial resistance and high mortality. Ongoing clinical trials are exploring novel anti-virulence agents, yet studies on how bacterial virulence affects PA infection outcomes is conflicting and data from real-world clinical populations is limited.

Methods: We studied a multicentre cohort of 773 adult patients with PA BSI consecutively collected during 7-years from sites in Europe and Australia.

Fosfomycin in bacteraemic urinary tract infection due to multidrug-resistant : insights of DOOR analysis of the FOREST trial.

Purpose: A analysis of data from a previously published clinical trial was conducted using the desirability of outcome ranking (DOOR) methodology with the aim provide additional information on the use of fosfomycin for the treatment of bacteraemic urinary tract infection (BUTI) caused by multi-drug-resistant (MDR) .

Methods: Three DOOR systems with five, six and seven categories, respectively were developed. Safety and efficacy were prioritised in all rankings, but step down to oral therapy and exposure to antibiotics with lower ecological impact were also considered in DOOR-6 and DOOR-7.

COVID-19 clinical phenotypes in vaccinated and nonvaccinated solid organ transplant recipients: a multicenter validation study.

Clinical phenotypes of COVID-19, associated with mortality risk, have been identified in the general population. The present study assesses their applicability in solid organ transplant recipients (SOTR) hospital-admitted by COVID-19. In a cohort of 488 SOTR, nonvaccinated (n = 394) and vaccinated (n = 94) against SARS-CoV-2, we evaluated 16 demographic, clinical, analytical, and radiological variables to identify the clinical phenotypes A, B, and C.

Expert consensus on antimicrobial resistance research priorities to focus development and implementation of antibacterial vaccines and monoclonal antibodies.

To reduce antimicrobial resistance (AMR), pathogen-specific AMR burden data are crucial to guide target selection for research and development of vaccines and monoclonal antibodies (mAbs). We identified knowledge gaps through previously conducted systematic reviews, which informed a Delphi expert consultation on future AMR research priorities and harmonisation strategies to support data-driven decision-making. Consensus (≥80% agreement) on importance and feasibility of research topics was achieved in two rounds, involving 24 of 39 and 19 of 24 invited experts, respectively.
