Multicenter StudyPsychiatric Symptoms in Acute Respiratory Distress Syndrome Survivors: A 1-Year National Multicenter Study.
To evaluate prevalence, severity, and co-occurrence of and risk factors for depression, anxiety, and posttraumatic stress disorder symptoms over the first year after acute respiratory distress syndrome. ⋯ Psychiatric symptoms occurred in two thirds of acute respiratory distress syndrome survivors with frequent co-occurrence. Sociodemographic characteristics and in-ICU opioid administration, rather than traditional measures of critical illness severity, should be considered in identifying the patients at highest risk for psychiatric symptoms during recovery. Given high co-occurrence, acute respiratory distress syndrome survivors should be simultaneously evaluated for a full spectrum of psychiatric sequelae to maximize recovery.

Multicenter StudyEvaluating Physical Outcomes in Acute Respiratory Distress Syndrome Survivors: Validity, Responsiveness, and Minimal Important Difference of 4-Meter Gait Speed Test.
To examine the reliability, validity, responsiveness, and minimal important difference of the 4-m gait speed test in acute respiratory distress syndrome survivors. ⋯ The 4-m gait speed is a reliable, valid, and responsive measure of physical function in acute respiratory distress syndrome survivors. The estimated minimal important difference will facilitate sample size calculations for clinical studies evaluating the 4-m gait speed test in acute respiratory distress syndrome survivors.

ReviewThe Role of Extracellular Adenosine Triphosphate in Ischemic Organ Injury.
Ischemic tissue injury contributes to significant morbidity and mortality and is implicated in a range of pathologic conditions, including but not limited to myocardial infarction, ischemic stroke, and acute kidney injury. The associated reperfusion phase is responsible for the activation of the innate and adaptive immune system, further accentuating inflammation. Adenosine triphosphate molecule has been implicated in various ischemic conditions, including stroke and myocardial infarction. ⋯ In this review, we aim to discuss the molecular mechanisms behind adenosine triphosphate-mediated ischemic tissue injury and evaluate the role of extracellular adenosine triphosphate in ischemic injury in specific organs, in order to provide a greater understanding of the pathophysiology of this complex process. We also appraise potential future therapeutic strategies to limit damage in various organs, including the heart, brain, kidneys, and lungs.
