The Influence of Hypercapnia and Atmospheric Pressure on the PaO2/FIO2 Ratio-Pathophysiologic Considerations, a Case Series, and Introduction of a Clinical Tool.
The ratio between Pao2 and Fio2 is used as a marker for impaired oxygenation and acute respiratory distress syndrome classification. However, any discrepancy between Fio2 and o2 fraction in the alveolus affects the Pao2/Fio2 ratio. Correcting the Pao2/Fio2 ratios using the alveolar gas equation may result in an improved reflection of the pulmonary situation. This study investigates the difference between standard and corrected Pao2/Fio2 in magnitude, its correlation with the mortality of acute respiratory distress syndrome classification, and trends over time. ⋯ Correcting the Pao2/Fio2 ratio for the alveolar gas equation predominantly affects patients with high ratios between Pao2 and Fio2 and Paco2 and at low atmospheric pressure. Using the corrected Pao2/Fio2 ratio for acute respiratory distress syndrome classification results in improved correlation with the 7-day ICU mortality and increases generalization among acute respiratory distress syndrome studies. The authors provide a free, web-based tool.

Diversity of Authors of Publications From the Canadian Critical Care Trials Group.
Diverse perspectives improve the quality of scholarly initiatives. The demographic and professional diversity of scientists who contribute to critical care research and publications has not been described for the Canadian Critical Care Trials Group. Our objective was to describe the diversity of authors of publications from the Canadian Critical Care Trials Group. ⋯ Authors of Canadian Critical Care Trials Group publications are diverse with regard to demographic and professional characteristics.

Observational StudyRisk of Dementia and Structural Brain Changes Following Nonneurological Infections During 9-Year Follow-Up.
Given the strong association between systemic inflammation and cognitive decline, we aimed to determine whether nonneurologic infections are associated with accelerated cognitive decline and structural changes in the brain using pre- and post-infection neuropsychologic assessments and repeated brain MR images. ⋯ In this 9-year observational follow-up study, sepsis episodes were associated with subsequent development of dementia. Nonneurologic infections had no effect on the trajectory of structural cerebral changes.

Concise Definitive Review for Reinitiation of Antidepressants, Antipsychotics, and Gabapentinoids in ICU Patients.
Concise definitive review of the reinitiation of prior-to-admission neuropsychiatric medications (NPMs) in ICU patients. ⋯ Additional larger studies are needed to evaluate the safety and efficacy of reinitiation of select prior-to-admission NPM to prevent agitation and delirium in ICU patients. Multiple factors for NPM reinitiation should be considered, such as reason for admission, organ dysfunction, available route of administration to provide prior-to-admission NPM, concomitant additional medications for agitation and delirium, and safety of these medications for patients in the ICU.
