Patient characteristics, clinical therapy survival were examined.155/156 (115 men, mean age 62 years, range 26-84 years) included. 67 (43%) had 90 superinfections, pneumonia dominated (78%). Superinfections associated receiving (66% vs 32%, p<0.0001), autoimmune disease (18% 5.7%, p<0.016) longer ICU stays (26 17 days, p<0,001). Invasive fungal infections reported exclusively dexamethasone-treated [8/67 (12%) 0/88 (0%), p<0.0001]. Unadjusted 90-day did not differ between or without (64% 73%, p=0.25), but was lower versus (58% 78%, p=0.007).

Abstract Acute bacterial infections are often treated empirically, with the choice of antibiotic therapy updated during treatment. The effects such rapid switching on evolution resistance in individual patients poorly understood. Here we find that low-frequency mutations emerge, contract, and even go to extinction within days changes therapy. We analyzed Pseudomonas aeruginosa populations sputum samples collected serially from 7 mechanically ventilated at onset respiratory infection. Combining short- long-read sequencing phenotyping 420 isolates revealed while new near-clonal, reflecting a recent colonization bottleneck, could emerge low frequencies then measured vivo select intact resistance-targeted deep amplicon (RETRA-Seq), which rare not detected by clinically used culture-based methods can increase nearly 40-fold over 5–12 response changes. Conversely, conferring antibiotics administered diminish extinction. Our results underscore how shapes dynamics short time scales, findings provide possibility for driving early stages infection designing patient-specific cycling strategies informed genomic surveillance.

Introduction: Ventilator-associated pneumonia (VAP) incidence is high among critically ill COVID-19 patients. Its attributable mortality remains underestimated, especially for unresolved episodes. Indeed, the impact of therapeutic failures and determinants that potentially affect are poorly evaluated. We assessed prognosis VAP in severe cases relapse, superinfection, treatment failure on 60-day mortality. Methods: evaluated a multicenter prospective cohort included adult patients with COVID-19, who required mechanical ventilation ≥48 h between March 2020 June 2021. investigated risk factors 30-day mortality, associated failure. Results: Among 1424 admitted to eleven centers, 540 were invasively ventilated 48 or more, 231 had episodes, which caused by Enterobacterales (49.8%), P. aeruginosa (24.8%), S. aureus (22%). The rate was 45.6/1000 ventilator days, cumulative at Day 30 60%. increased duration without modifying crude death (47.6% vs. 44.7% VAP) resulted 36% increase hazard. Late-onset represented 179 episodes (78.2%) responsible 56% rates relapse superinfection 45% 39.5%, respectively, but did not Superinfection more frequently related ECMO first episode non-fermenting bacteria. an absence highly susceptible microorganisms vasopressor need onset. Conclusions: VAP, mainly late-onset death, similar observed other mechanically due difficult-to-treat microorganisms, pharmacokinetic alterations induced renal replacement therapy, shock, likely explains

Objectives: Ventilator-associated lower respiratory tract infections (VALRTIs) are among the most common ICU-acquired in patients receiving invasive mechanical ventilation (IMV). Immunocompromised may have a incidence of VALRTI when compared with nonimmunocompromised patients, but influence type immunosuppression on epidemiology has not been investigated. The study objectives were to assess association incidence, microbiology, and outcomes (ICU mortality, ICU length stay, duration IMV) related bacterial pathogens. Design: Multicenter, international retrospective cohort study. Setting: One hundred eighteen ICUs (118) nine countries. Patients: Eight fifty-four immunocompromised adult (median age, 65 yr; 57.6% males) requiring IMV for greater than 48 hours, including 162 hematologic malignancies. Interventions: None. Measurements Main Results: Patients malignancies had 28-day cumulative other types (13.6% vs. 20.1%; adjusted cause-specific hazard ratio, 0.61; 95% CI, 0.37–0.97), mostly due ventilator-associated pneumonia (9.3% 13.9%). proportion cases multidrug-resistant bacteria was similar between groups. Occurrence associated an increased mortality longer this effect independent immunosuppression. Conclusions: immunosuppression, mainly pneumonia.

Abstract Rationale Early corticosteroid treatment is used to treat COVID-19-related acute respiratory distress syndrome (ARDS). Infection a well-documented adverse effect of therapy. Objectives To determine whether early therapy COVID-19 ARDS was associated with ventilator-associated pneumonia (VAP). Methods We retrospectively included adults COVID-19-ARDS requiring invasive mechanical ventilation (MV) for ≥ 48 h at any 15 intensive care units in 2020. divided the patients into two groups based on they did or not receive corticosteroids within 24 h. The primary outcome VAP incidence, death and extubation as competing events. Secondary outcomes were day 90-mortality, MV duration, other organ dysfunctions, characteristics. Measurements main results Of 670 (mean age, 65 years), 369 301 corticosteroids. cumulative incidence higher (adjusted hazard ratio [aHR] 1.29; 95% confidence interval [95% CI] 1.05–1.58; P = 0.016). Antibiotic resistance bacteria different between (odds 0.94, CI 0.58–1.53; 0.81). 90-day mortality 30.9% 24.3% without corticosteroids, nonsignificant difference after adjustment SOFA score, occurrence (aHR 1.15; 0.83–1.60; 0.411). 1.86; 1.33–2.61; 0.0003). Conclusions COVID-19-ARDS. Although mortality, not. Longitudinal randomized controlled trials are warranted.

Patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-COV 2) and requiring intensive care unit (ICU) have a high incidence of hospital-acquired infections; however, data regarding hospital acquired bloodstream infections (BSI) are scarce. We aimed to investigate risk factors outcome BSI in critically ill infectious disease-19 (COVID-19) patients.We performed an ancillary analysis multicenter prospective international cohort study (COVID-ICU study) that included 4010 COVID-19 ICU patients. For present analysis, only those primary (death within 90 days from admission) or status were included. Risk for analyzed using Fine Gray competing model. Then, comparison, 537 BSI-patients matched controls propensity score matching.Among patients, 780 (19.5%) total 1066 (10.3 per 1000 patients at risk) whom 92% ICU. Higher SAPS II, male gender, longer time admission antiviral drug before independently associated increased BSI, interestingly, this decreased over time. was shorter death overall population (adjusted hazard ratio (aHR) 1.28, 95% CI 1.05-1.56) and, set, had higher mortality rate (39% vs 33% p = 0.036). accounted 3.6% population.COVID-19 especially early after admission, increases severity but not corticosteroids use. is rate.
