Objectives: Peer review typically relies on experts volunteering their time to review research. This process presents challenges for journals that may face a shortage of qualified referees, resulting in either delay in handling papers or less thorough review than is optimal. We experimentally tested the impact of providing cash incentives to complete peer review assignments at Critical Care Medicine.

Despite decades of clinical trials, there are no specific treatments; care of the nearly 50 million annual cases worldwide is limited to antimicrobials and supportive measures. A primary prevention strategy may therefore be of value.

Objectives: Determine the impact of corticosteroid administration on 90-day mortality (primary outcome) in patients admitted to a critical care unit with CS.
Design, Setting, And Participants: In this retrospective cohort study, we used the critical care database of Medical Information Mart for Intensive Care-IV, and included all adult patients diagnosed with CS excluding repeated admissions, patients with adrenal insufficiency, those receiving baseline corticosteroids, and those requiring extracorporeal life support.
Purpose: We hypothesised that the biological heterogeneity of sepsis may highlight sepsis subtypes with differences in response to intravenous vitamin C treatment in the Lessening Organ Dysfunction with VITamin C (LOVIT) trial. Our aims were to identify sepsis subtypes and to test whether sepsis subtypes have differences in treatment effect to vitamin C and describe putative biological effects of vitamin C treatment.
Methods: We measured biomarkers of inflammation, at baseline and at 7 days post-randomisation, in 457/863 (53.
Introduction: Survivors of critical illness and their caregivers are at risk for long-term cognitive, physical and psychiatric impairments known as post-intensive care syndrome (PICS) and PICS-family, respectively. This study will assess the feasibility of a randomised controlled trial (RCT) evaluating an intensive care unit (ICU) follow-up care bundle versus standard-of-care for ICU patients and their caregivers.
Methods And Analysis: This is a single-centre feasibility study.
Background: Most Canadians receive their care in community hospitals, yet most clinical research is conducted in academic hospitals. This study aims to compare patients with community acquired pneumonia (CAP) treated in academic and community hospitals with respect to their demographics, clinical characteristics, treatments and outcomes.
Methods: This nested observational cohort substudy of the Community Acquired Pneumonia: Toward InnoVAtive Treatment (CAPTIVATE) trial included 1,329 hospitalized adults with CAP recruited between March 1st, 2018 and September 31st, 2023 from 15 Canadian hospitals.
Atrial fibrillation (AF) is a common arrhythmia encountered in acute and critical illness and is associated with poor short and long-term outcomes. Given the consequences of developing AF, research into prevention, prediction and treatment of this arrhythmia in the critically ill are of great potential benefit, however, study of AF in critically ill patients faces unique challenges, leading to a sparse evidence base to guide management in this population. Major obstacles to the study of AF in acute and critical illness include absence of a common definition, challenges in designing studies that capture complex etiology and assess causality, lack of a clear outcome set, difficulites in recruitment in acute environments with respect to timing, consent, and workflow, and failure to embed studies into clinical care platforms and capitalize on emerging technologies.

By this metric, research in sepsis is far behind other areas of medicine-the word itself conflates multiple different disease mechanisms, whilst excluding noninfectious syndromes (e.g.

Current anti-inflammatory therapies are effective but are given systemically and have significant side effects. Furosemide has anti-inflammatory properties, can be administered by inhalation, and is inexpensive.

VAP results either from aspiration of pathogen-contaminated oropharyngeal secretions or contaminated biofilms that form on endotracheal tubes (ETTs) after intubation. VAP results in increased duration of mechanical ventilation, increased intensive care unit and hospital length of stay, increased risk of death and increased healthcare costs.

Individualized CA-derived blood pressure targets are poorly characterized in critically ill patients and the association with intensive care unit (ICU) delirium is unknown. Our objectives were to characterize optimal mean arterial pressure (MAP) ranges in critically ill adults without brain injury and determine whether deviations from these targets contribute to ICU delirium.

Long-term kidney replacement therapy and critical illness are independently linked to acute and prolonged cognitive impairment, and structural brain pathology. Poor regional cerebral oxygenation (rSO) may be a contributing factor.

We hypothesized that vaccination alters outcomes of patients hospitalized with COVID-19 during the Omicron wave and that these patients have different characteristics and outcomes than in previous waves.
Methods: This is a substudy of the Host Response Mediators in Coronavirus (COVID-19) Infection (ARBs CORONA I) trial, which included adults admitted to hospital with acute COVID-19 up to July 2022 from 9 hospitals in British Columbia, Ontario and Quebec.
The Society of Critical Care Medicine (SCCM) Reviewer Academy seeks to train and establish a community of trusted, reliable, and skilled peer reviewers with diverse backgrounds and interests to promote high-quality reviews for each of the SCCM journals. Goals of the Academy include building accessible resources to highlight qualities of excellent manuscript reviews; educating and mentoring a diverse group of healthcare professionals; and establishing and upholding standards for insightful and informative reviews. This manuscript will map the mission of the Reviewer Academy with a succinct summary of the importance of peer review, process of reviewing a manuscript, and the expected ethical standards of reviewers.

Despite efforts to improve the informed consent process, participants are seldom provided sufficient information regarding research, hindering their ability to make informed decisions. These issues are particularly pervasive among patients experiencing acute illness or neurological impairment, both of which may impede their capacity to provide consent.
View Article and Find Full Text PDFHostSeq was launched in April 2020 as a national initiative to integrate whole genome sequencing data from 10,000 Canadians infected with SARS-CoV-2 with clinical information related to their disease experience. The mandate of HostSeq is to support the Canadian and international research communities in their efforts to understand the risk factors for disease and associated health outcomes and support the development of interventions such as vaccines and therapeutics. HostSeq is a collaboration among 13 independent epidemiological studies of SARS-CoV-2 across five provinces in Canada.
