Prognostic Value of Lung Injury Biomarkers in Patients Hospitalized With COVID-19 Without Respiratory Failure at Admission

CONCLUSIONS: Baseline levels of plasma lung injury biomarkers are significantly associated with progression to respiratory failure or death among hospitalized COVID-19 patients without respiratory failure at admission. These findings support the potential utility of measuring lung injury biomarkers in patients hospitalized without respiratory failure and should be tested in more heterogeneous patient groups including non-COVID-19 cohorts.

Québec Wildfires and Respiratory Emergency Department Visits in Charlottesville, Virginia

The decline in air quality from wildfires is known to have detrimental health impacts locally, but less is known about the effects far from the source. To address this gap, we analyzed visits to the University of Virginia Emergency Department from 2017 to 2023 by examining the impact of elevated PM(2.5) levels on respiratory visits. For this analysis, high exposure days were defined as those with PM(2.5) levels 2 or more standard deviations above the 2017-2023 average, specifically during the...

A Usability Survey of a Quality Improvement Data Visualization Tool Among Medical Intensive Care Unit Nurses

CONCLUSIONS: The Bundle Board demonstrated good usability among ICU Nurses, who provided substantive feedback for its improvement. These observations may be generalizable to other comparable interventions. Iterative feedback from end-users is vital to developing and implementing a digital health intervention. Our study provides a framework for performing a usability analysis within a specific clinician population and environment.

Distinct type 1 immune networks underlie the severity of restrictive lung disease after COVID-19

The variable origins of persistent breathlessness after coronavirus disease 2019 (COVID-19) have hindered efforts to decipher the immunopathology of lung sequelae. Here we analyzed hundreds of cellular and molecular features in the context of discrete pulmonary phenotypes to define the systemic immune landscape of post-COVID lung disease. Cluster analysis of lung physiology measures highlighted two phenotypes of restrictive lung disease that differed according to their impaired diffusion and...
