The rapid processing of perfusion and diffusion (RAPID) system for automating perfusion and diffusion data from head computed tomography has improved acute ischemic stroke treatment by quickly and accurately identifying those patients who may benefit from thrombectomy. Collateral scoring (CS) of cerebral arteries using computed tomography angiography (CTA) has proven useful in predicting postintervention infarct volumes and functional outcomes in ischemic stroke patients. Here we evaluate the relationship between CS and RAPID software in an effort to augment triage and provide improved predictability of functional outcomes in ischemic stroke patients. ⋯ CS on CTA may be a useful way to identify patients who would benefit from mechanical thrombectomy and predict functional outcomes postintervention. CS may allow the stroke team to optimize the care of patients who may not be able to obtain RAPID analysis.

This study was designed to analyze the results of recurrent glioblastoma (GBM) treatment, investigate the changes in molecular expression on paired primary and recurrent tumor specimens of GBM, and evaluate the effect of these changes on patient survival. ⋯ The extent of resection and adjuvant treatment was important for prolonged survival. Reoperation without adjuvant treatment was not effective for prolonged survival. Initial and follow-up PD-L1 expression from both operations did not influence patient survival.
