BACKGROUND Patients with adult respiratory distress syndrome (ARDS) and acute lung injury (ALI) have low concentrations of disaturated-phosphatidylcholine and surfactant protein-B in bronchoalveolar lavage fluid. No information is available on their turnover. OBJECTIVES To analyze disaturated-phosphatidylcholine and surfactant protein-B turnover in patients with ARDS/ALI and in human adults w...

Early recognition of patients at high risk of acute lung injury (ALI) is critical for successful enrollment of patients in prevention strategies for this devastating syndrome. We aimed to develop and prospectively validate an ALI prediction score in a population-based sample of patients at risk. In a retrospective derivation cohort, predisposing conditions for ALI were identified at the time of...

Acute lung injury (ALI) during hematopoietic stem cell transplant (HSCT) is associated with substantial morbidity; however, the frequency of ALI in HSCT patients is poorly characterized. Platelets are postulated to play a critical role in the pathogenesis of ALI. Using a transfusion trial of pathogen inactivated platelet components (PC-Test) compared with conventional PC (Reference) populated w...

BACKGROUND Few emergency department (ED) evaluations on acute lung injury (ALI) have been carried out; hence, we sought to describe a cohort of hospitalized ED patients at risk for ALI development. METHODS Patients presenting to the ED with at least one predisposing condition to ALI were included in this study, a subgroup analysis of a multicenter observational cohort study (USCIITG-LIPS 1). ...

BACKGROUND Differential diagnosis between acute cardiogenic pulmonary edema (APE) and acute lung injury/acute respiratory distress syndrome (ALI/ARDS) may often be difficult. We evaluated the ability of chest sonography in the identification of characteristic pleuropulmonary signs useful in the diagnosis of ALI/ARDS and APE. METHODS Chest sonography was performed on admission to the intensive...

Mortality associated with acute lung injury (ALI) induced by lipopolysaccharide (LPS) remains high in humans, warranting improved treatment and prevention strategies. ALI is characterized by the expression of proinflammatory mediators and extensive neutrophil influx into the lung, followed by severe lung damage. Understanding the pathogenesis of LPS-induced ALI is a prerequisite for designing b...

This report explores the efficacy of existing therapies for acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), primarily in terms of clinically important outcomes such as the duration of mechanical ventilation and hospital mortality. Of the 15 therapies reviewed, the strongest evidence suggests that ALI/ARDS should be managed with a low-tidal-volume, pressure-limited approa...

Cysteine-rich protein-61 (CYR61), also known as connective tissue growth factor, CYR61, and nephroblastoma overexpressed gene 1 (CCN1), is a heparin-binding protein member of the CCN family of matricellular proteins. Gene expression profiles showed that Cyr61 is upregulated in human acute lung injury (ALI), but its functional role is unclear. We hypothesized that CYR61 contributes to ALI in mic...
