Long-term Mental Health Morbidity in Adult Survivors of COVID-19 Critical Illness - A Population-based Cohort Study.

Background: Survivorship after coronavirus disease 2019 (COVID-19) critical illness may be associated with important long-term sequelae, but little is known regarding mental health outcomes.

Research Question: What is the association between COVID-19 critical illness and new post-discharge mental health diagnoses.

Study Design: AND METHODS: We conducted a population-based cohort study in Ontario, Canada (January 1, 2020-March 31, 2022).

Exploring the quality of end-of-life care in the intensive care unit: a qualitative multiple case study approach with family members of Muslim patients.

Objective: Muslim patients are an underrepresented community in end-of-life care research, with little evidence around factors that influence the quality and experience of care. The aim of this study was to explore the quality of end-of-life care in the intensive care unit (ICU) from the perspective of next-of-kin family members of Muslim patients.

Design: A qualitative multiple case study design using semistructured interviews with family members of Muslim patients.

Genomic regions associated with spot blotch resistance in elite barley breeding populations.

Unlabelled: Spot blotch (SB), a prevalent foliar disease of barley, is caused by the hemibiotrophic fungal pathogen . Predominately occurring in humid growing regions worldwide, SB can result in yield losses of up to 30%. Genetic resistance remains the most effective strategy for disease management; however, most Australian barley cultivars exhibit susceptibility despite the previous identification of major resistance loci.

Eligibility Criteria of Randomized Clinical Trials in Critical Care Medicine.

Importance: Eligibility criteria for randomized clinical trials (RCTs) are designed to select clinically relevant patient populations. However, not all eligibility criteria are strongly justified, potentially excluding marginalized groups, and limiting the generalizability of trial findings.

Objective: To summarize and evaluate the justification of exclusion criteria in published RCTs in critical care medicine.

Development and usability testing of a multifaceted intervention to reduce low-value injury care.

Background: Multifaceted interventions that address barriers and facilitators have been shown to be most effective for increasing the adoption of high-value care, but there is a knowledge gap on this type of intervention for the de-implementation of low-value care. Trauma is a high-risk setting for low-value care, such as unnecessary diagnostic imaging and the use of specialized resources. The aim of our study was to develop and assess the usability of a multifaceted intervention to reduce low-value injury care.

Diagnostic challenges of long COVID in children: a survey of pediatric health care providers' preferences and practices.

Introduction: Given the challenges in diagnosing children with long COVID, we sought to explore diagnostic practices and preferences among clinicians.

Methods: A ten-question survey assessed pediatric providers' clinical decision making for identifying and evaluating long COVID in children. Of the 120 survey respondents, 84 (70%) were physicians, 31 (26%) nurse practitioners, and 5 (4%) physician assistants.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Disparities in anti-nucleocapsid and anti-spike SARS-CoV-2 antibody prevalence in NYC - April-October 2021.

Purpose: Between April-October 2021, the New York City (NYC) Health Department conducted a serosurvey to assess prevalence of SARS-CoV-2 antibodies in NYC adults as part of continued COVID-19 surveillance efforts.

Methods: Whole blood specimens were collected from 1035 adult NYC residents recruited from an annual population-based health surveillance survey. Specimens were tested for the presence of anti-SARS-CoV-2 spike protein (anti-spike) and anti-SARS-CoV-2 nucleocapsid protein (anti-nucleocapsid) antibodies.

Rejection in the setting of combined Heart and Liver Transplantation.

Introduction: Each year the number of combined heart-liver transplants (HLT) increases, with two distinct patient populations proceeding down this pathway. The first are patients with congenital heart disease (CHD), most commonly single ventricle patients palliated with Fontan. The second group are those with long standing congestive hepatopathy, amyloidosis, hemochromatosis, or alcohol induced myopathies and liver disease.

The burden of COVID-19 care in community and academic intensive care units in Ontario, Canada: a retrospective cohort study.

Purpose: During the COVID-19 pandemic, neighbourhoods with high material deprivation and high proportions of racialized Canadians were disproportionately affected by COVID-19. Many of these neighbourhoods were served by community hospitals. We sought to compare the burden of COVID-19 care in community and academic intensive care units (ICUs) in Ontario, Canada.

Ebola disease: bridging scientific discoveries and clinical application.

The west Africa Ebola disease epidemic (2014-16) marked a historic change of course for patient care during emerging infectious disease outbreaks. The epidemic response was a failure in many ways-a slow, cumbersome, and disjointed effort by a global architecture that was not fit for purpose for a rapidly spreading outbreak. In the most affected countries, health-care workers and other responders felt helpless-dealing with an overwhelming number of patients but with few, if any, tools at their disposal to provide high-quality care.

Effect of omalizumab on inflammatory markers in COVID-19: an exploratory analysis of the COVID-19 immunologic antiviral therapy with omalizumab (CIAO) trial.

Background: The CIAO trial recently demonstrated a probable clinical benefit of omalizumab in the treatment of severe COVID-19; however, the mechanism underlying this benefit remains unclear. Therefore, we sought to longitudinally assess the impact of omalizumab on serum cytokines in CIAO trial patients to determine its mechanism of action.

Methods: Blood samples were collected on days 0, 2, 7, and 14 from patients recruited into the CIAO trial and who consented to this substudy.

Language Preference, Surgical Wait Time, and Outcomes Among Older Adults With Hip Fracture.

Importance: Patients with a non-English language preference served within English-dominant health care settings are at increased risk of adverse events that may be associated with communication barriers and inequitable access to care.

Objective: To investigate the association of non-English language preference with surgical wait time and postoperative outcomes in older patients undergoing hip fracture repair.

Design, Setting, And Participants: This population-based, retrospective cohort study was conducted using linked databases to measure surgical wait time and postoperative outcomes among older adults (aged ≥66 years) in Ontario, Canada, who underwent hip fracture surgery between January 1, 2017, and December 31, 2022.

Community versus academic hospital community-acquired pneumonia patients: a nested cohort 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.

An International Factorial Vignette-Based Survey of Intubation Decisions in Acute Hypoxemic Respiratory Failure.

Objectives: Intubation is a common procedure in acute hypoxemic respiratory failure (AHRF), with minimal evidence to guide decision-making. We conducted a survey of when to intubate patients with AHRF to measure the influence of clinical variables on intubation decision-making and quantify variability.

Design: Factorial vignette-based survey asking "Would you recommend intubation?" Respondents selected an ordinal recommendation from a 5-point scale ranging from "Definite no" to "Definite yes" for up to ten randomly allocated vignettes.

Antibiotic Treatment for 7 versus 14 Days in Patients with Bloodstream Infections.

Background: Bloodstream infections are associated with substantial morbidity and mortality. Early, appropriate antibiotic therapy is important, but the duration of treatment is uncertain.

Methods: In a multicenter, noninferiority trial, we randomly assigned hospitalized patients (including patients in the intensive care unit [ICU]) who had bloodstream infection to receive antibiotic treatment for 7 days or 14 days.

Using multi-level regression to determine associations and estimate causes and effects in clinical anesthesia due to patient, practitioner and hospital or health system practice variability.

In this research methods tutorial of clinical anesthesia, we will explore techniques to estimate the influence of a myriad of factors on patient outcomes. Big data that contain information on patients, treated by individual anesthesiologists and surgical teams, at different hospitals, have an inherent multi-level data structure (Fig. 1).

Trends in characteristics, interventions, and outcomes of hospitalized patients with COVID-19 in Canada: a multicentre prospective cohort study.

Purpose: Our objective was to investigate the temporal trends in baseline characteristics, interventions, and clinical outcomes in patients hospitalized with COVID-19 in Canada over five pandemic waves.

Methods: We conducted a multicentre prospective cohort study enrolling adults and children admitted with COVID-19 from 47 Canadian hospitals. We compared characteristics, interventions, and outcomes of patients across five distinct pandemic waves.

Antifoams in non-aqueous diesel fuels: Thin liquid film dynamics and antifoam mechanisms.

HypothesisFoaming in diesel fuels is not well understood and leads to operational challenges. To combat deleterious effects of foaming, diesel formulations can include additives called antifoams. Existing antifoams, unfortunately, are inherently ash-generating when combusted, with unknown environmental impacts.
