This is not an indication of a security issue such as a virus or attack.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.We previously addressed this heterogeneity by identifying three putative subclasses of children with septic shock based exclusively on a 100-gene expression signature. After subclassification, the clinical database was mined for phenotyping.Here we attempted to prospectively validate the existence of these gene expression-based subclasses in a validation cohort. Subclass A patients had higher illness severity relative to subclasses B and C, as measured by maximal organ failure, fewer ICU-free days, and a higher PRISM score. uses cookies to improve performance by remembering your session ID when you navigate from page to page.

Septic shock heterogeneity has important implications for clinical trial implementation and patient management. Using computer-based image analysis, patients were classified into 1 of 3 subclasses (“A”, “B”, or “C”) based on color and pattern similarity relative to reference mosaics generated from the original derivation cohort.

Subclass A patients had higher illness severity relative to subclasses B and C as measured by maximal organ failure, fewer intensive care unit-free days, and a higher Pediatric Risk of Mortality score. A major challenge in critical care medicine is the development of clinically feasible stratification strategies to manage this heterogeneity for the design of more effective clinical trials and individualized patient management [3, 4].

Patients in subclass A were characterized by repression of genes corresponding to adaptive immunity and glucocorticoid receptor signaling. We are addressing the challenge of septic shock heterogeneity by leveraging the discovery potential of whole-genome expression profiling [5].

  1. The Neanderthals are thought to have arrived there around 300,000 BC, but seem to have died out by about by 30,000 BC, presumably unable to compete with modern humans during a period of cold weather.
