Article Synopsis
  • The study investigates how bacteria adapt to patients over long hospital stays, focusing on antimicrobial resistance and metabolic changes in the gut during intensive care unit (ICU) admissions.
  • Weekly rectal swabs from ICU patients were analyzed to track the evolution of enteric bacterial populations, revealing that only a small number of patients harbored distinct strains.
  • Key findings included a persistent strain that exhibited significant changes in drug resistance, highlighting the impact of genetic mutations on bacterial behavior and patient treatment challenges.

Background: Determining which patients with ARDS are most likely to benefit from lung recruitment maneuvers is challenging for physicians. The aim of this study was to assess whether the single-breath simplified decremental PEEP maneuver, which evaluates potential lung recruitment, may predict a subject's response to lung recruitment maneuvers, followed by PEEP titration.

Methods: We conducted a pilot prospective single-center cohort study with a 3-step protocol that defined sequential measurements.

Background: Pain management is an essential and complex issue for non-communicative patients undergoing sedation in the intensive care unit (ICU). The Behavioral Pain Scale (BPS), although not perfect for assessing behavioral pain, is the gold standard based partly on clinical facial expression. , an automatic pain assessment tool based on facial expressions in critically ill patients, is a much-needed innovative medical device.

The aim of this study was to evaluate the proportion of resistance to a temocillin, tigecycline, ciprofloxacin, and chloramphenicol phenotype called t2c2 that resulted from mutations within the locus among extended-spectrum β-lactamases (ESBL-E) isolated in three intensive care units for 3 years in a French university hospital. Two parallel approaches were performed on all 443 ESBL-E included: (i) the minimal inhibitory concentrations of temocillin, tigecycline, ciprofloxacin, and chloramphenicol were determined and (ii) the genomes obtained from the Illumina sequencing platform were analyzed to determine multilocus sequence types, resistomes, and diversity of several -associated genes including operon. Among the 443 ESBL-E strains included, isolates of ( = 194), ( = 122), and complex () ( = 127) were found.

Background: Due to aging population and increasing part of immunocompromised patients, a raise in life-threatening organ damage related to VZV can be expected. Two retrospective studies were already conducted on VZV in ICU but focused on specific organ injury. Patients with high-risk of VZV disease still must be identified.
