Article Synopsis
- Hospital-acquired bloodstream infections (HA-BSI) in ICU patients can be life-threatening, and this study aimed to see how early adequate antibiotic treatment affects 28-day mortality rates for patients who survive at least one day after infection onset.
- Using data from a multicenter study with 2,418 patients, researchers found that those who received adequate treatment within 24 hours had a lower 28-day mortality rate (32.8%) compared to those who were inadequately treated (40%).
- The study concluded that inadequate antibiotic therapy within 24 hours contributes significantly to 28-day mortality, indicating that quicker treatment could greatly improve patient outcomes in cases of HA-BSI.
Purpose: Older adults admitted to the intensive care unit (ICU) usually have fair baseline functional capacity, yet their age and frailty may compromise their management. We compared the characteristics and management of older (≥ 75 years) versus younger adults hospitalized in ICU with hospital-acquired bloodstream infection (HA-BSI).
Methods: Nested cohort study within the EUROBACT-2 database, a multinational prospective cohort study including adults (≥ 18 years) hospitalized in the ICU during 2019-2021.
Purpose: The primary objective of this study was to evaluate the associations between centre/country-based factors and two important process and outcome indicators in patients with hospital-acquired bloodstream infections (HABSI).
Methods: We used data on HABSI from the prospective EUROBACT-2 study to evaluate the associations between centre/country factors on a process or an outcome indicator: adequacy of antimicrobial therapy within the first 24 h or 28-day mortality, respectively. Mixed logistical models with clustering by centre identified factors associated with both indicators.
Purpose: In the critically ill, hospital-acquired bloodstream infections (HA-BSI) are associated with significant mortality. Granular data are required for optimizing management, and developing guidelines and clinical trials.
Methods: We carried out a prospective international cohort study of adult patients (≥ 18 years of age) with HA-BSI treated in intensive care units (ICUs) between June 2019 and February 2021.
Article Synopsis
- Intravenous thrombolysis (IVT) combined with mechanical thrombectomy (MT) for patients with M2 occlusions shows a significantly better 90-day functional outcome compared to MT alone, according to a study analyzing data from the Endovascular Treatment in Ischemic Stroke (ETIS) registry.
- The analysis included 1,132 patients, with 570 receiving prior IVT, and found that combining IVT with MT resulted in a 59.8% favorable outcome versus 44.7% for MT alone, without increasing complications.
- These findings suggest that administering IVT prior to MT in M2 occlusions could enhance patient recovery, highlighting the potential benefits of this combined treatment approach.
Background: Nosocomial pneumonia is commonly associated with antimicrobial-resistant Gram-negative pathogens. We aimed to assess the efficacy and safety of ceftazidime-avibactam in patients with nosocomial pneumonia, including ventilator-associated pneumonia, compared with meropenem in a multinational, phase 3, double-blind, non-inferiority trial (REPROVE).
Methods: Adults with nosocomial pneumonia (including ventilator-associated pneumonia), enrolled at 136 centres in 23 countries, were randomly assigned (1:1) to 2000 mg ceftazidime and 500 mg avibactam (by 2 h intravenous infusion every 8 h) or 1000 mg meropenem (by 30-min intravenous infusion every 8 h) for 7-14 days; regimens were adjusted for renal function.
