INTRODUCTION Plasma levels of cell-free hemoglobin are associated with mortality in patients with sepsis; however descriptions of independent associations with free hemoglobin and free heme scavengers, haptoglobin and hemopexin, are lacking beyond their description as acute phase reactants. We sought to determine the association of plasma levels of(More)
INTRODUCTION Despite recent modifications, the clinical definition of the acute respiratory distress syndrome (ARDS) remains non-specific, leading to under-diagnosis and under-treatment. This study was designed to test the hypothesis that a biomarker panel would be useful for biologic confirmation of the clinical diagnosis of ARDS in patients at risk of(More)
BACKGROUND The aim of this study was to determine the association between 25-hydroxyvitamin D (25-OHD) levels at the onset of critical illness and the development of acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in patients with sepsis or trauma. METHODS We performed two nested case-control studies of 478 patients with sepsis and trauma(More)
BACKGROUND The storage duration of red blood cells transfused to critically ill patients is associated with increased morbidity and mortality. Whether the association exists between storage duration of red blood cells transfused to patients with sepsis and the risk of developing ALI/ARDS is unknown. We aimed to determine the association of the storage(More)
BACKGROUND Hyperoxia is common early in the course of resuscitation of critically ill patients. It has been associated with mortality in some, but not all, studies of cardiac arrest patients and other critically ill cohorts. Reasons for the inconsistency are unclear and may depend on unmeasured patient confounders, the timing and duration of hyperoxia,(More)
The acute respiratory distress syndrome commonly accompanies critical illness and is associated with significant morbidity and mortality. The implementation of life saving therapies is dependent on accurately identifying patients with this syndrome; however, beyond clinical definitions, we lack ancillary tests aimed at this specific diagnosis.

Acute massive pulmonary embolism results in a rise in pulmonary vascular resistance and acute right ventricular dilation and systolic dysfunction. In unstable patients who cannot safely undergo computed tomography, echocardiography can often provide direct and indirect evidence of pulmonary embolism. We present a case in which clinical and echocardiographic(More)
