Ventilatory ratio (VR) is a simple bedside index reflecting pulmonary dead space and is associated with outcomes in acute respiratory distress syndrome (ARDS). This study developed and validated separate 30-day mortality prediction models for high and low VR subgroups using multicenter critical care databases. Subgroup-specific models demonstrated superior predictive performance compared with cross-applied models, highlighting the importance of VR-based stratification for improving prognostic accuracy and supporting more individualized ARDS management strategies.
Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA’s James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou’s College of Arts and Science spotted these strange objects, which seem like one galactic thing but have the unmistakable fingerprints of something else entirely.
Advanced quantum detectors designed at Texas A&M University are reinventing the search for dark matter, an unseen force that science has yet to explain.
A new study led by WashU planetary scientists suggests the icy moon lacks the undersea activity needed to support life.
Our galaxy’s supermassive black hole is famous for being one of the dimmest in the universe. Evidence from a new space telescope shows that might not always have been the case. Sagittarius A*, located at the center of the Milky Way Galaxy, appears to have flared dramatically sometime within the past few hundred to 1,000 years, according to X-ray emissions observed by the XRISM space telescope. These surprising findings unveil new details of how supermassive black holes evolve. They also teach astronomers lessons about the history of our cosmic home.
