Cell-free DNA--a marker to predict ischemic brain damage in a rat stroke experimental model.
The animal model of stroke that is most frequently used is a rat model of focal brain ischemia caused by middle cerebral artery occlusion (MCAO). Several studies have reported a link between levels of cell-free DNA (CFD) and neurologic outcome in human stroke. The purpose of this study was to assess brain injury and measure CFD levels in 2 models of MCAO in rats, and to determine whether brain injury correlates with CFD. ⋯ We found that CFD levels correlate well with the extent of ischemic injury, brain edema, and neurologic outcome in rats 24 hours post-MCAO. We have also shown that CFD correlates well with the expected temporal progression of ischemic injury. These findings place CFD in a unique place as a biomarker for stroke, both experimentally and possibly clinically.

Predictive model for survival among neurosurgical intensive care patients.
Models for prediction of outcome of intensive care patients greatly help the physician to make decisions and are also important for risk stratification in clinical research and quality improvement. At present, there are no major predictive models for neurosurgical intensive care unit (NSICU) patients. This study aimed to develop a predictive model for survival in NSICU patients. ⋯ In the current model of prediction of survival in a neurosurgical ICU, age, diagnosis, GCS, pupillary status, serum albumin, and serum sodium are independent predictors of survival in NSICU patients.
