Black Hole Sign: Novel Imaging Marker That Predicts Hematoma Growth in Patients With Intracerebral Hemorrhage Clinical Sciences
Conclusions— The CT black hole sign could be used as a simple and easy-to-use predictor for early hematoma growth in patients with intracerebral hemorrhage.

Echoing Plaque Activity of the Coronary and Intracranial Arteries in Patients With Stroke Clinical Sciences
Conclusions— Plaques within the intracranial and coronary arteries behave in similar ways. Our results suggest the need to evaluate and treat other vascular trees in patients with vulnerable plaques within a single arterial system.

Recanalization Modulates Association Between Blood Pressure and Functional Outcome in Acute Ischemic Stroke Clinical Sciences
Conclusions— Systemic BP in the first 24 hours after ischemic stroke influences 3-month clinical outcome. This association is dependent on the revascularization status.

Degree and Timing of Intensive Blood Pressure Lowering on Hematoma Growth in Intracerebral Hemorrhage: Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial-2 Results Brief Reports
Conclusions— Intensive BP lowering with greater SBP reduction, which is achieved quickly and maintained consistently, seems to provide protection against hematoma growth for 24 hours. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00716079.

Timing of Occurrence Is the Most Important Characteristic of Spot Sign Clinical Sciences
Conclusions— Redefining the spot sign based on timing of contrast leakage on CTP to determine early-occurring spot sign improves the specificity for predicting HE and 3-month mortality. The use of early-occurring spot sign could improve the selection of ICH patients for potential hemostatic therapy.

Heritability and Genome-Wide Association Analyses of Intracranial Carotid Artery Calcification: The Rotterdam Study Clinical Sciences
Conclusions— ICAC volume is a heritable trait, which is partly explained by common genetic variation. We identified specific genetic variants associated with ICAC, which given the importance of ICAC in stroke risk, needs replication in larger-scale studies to further elucidate its genetic basis.

Leakage Sign for Primary Intracerebral Hemorrhage: A Novel Predictor of Hematoma Growth Clinical Sciences
Conclusions— The results indicate that the leakage sign is a useful and sensitive method to predict hematoma expansion.

Association Between Time to Reperfusion and Outcome Is Primarily Driven by the Time From Imaging to Reperfusion Clinical Sciences
Conclusions— Time to reperfusion is negatively associated with favorable outcome, being CT to reperfusion, as opposed to onset to CT, the main determinant of this association. In addition, OTR was strongly associated to outcome in patients with low ASPECTS scores but not in patients with high ASPECTS scores. Clinical Trial Registration— URL: http://www.clinicaltrials.gov.

Streamlined Hyperacute Magnetic Resonance Imaging Protocol Identifies Tissue-Type Plasminogen Activator-Eligible Stroke Patients When Clinical Impression Is Stroke Mimic Clinical Sciences
Conclusions— A streamlined hMRI protocol permitted tPA administration to a small, but significant, subset of AIS patients initially considered to have SM.

Magnitude of Hematoma Volume Measurement Error in Intracerebral Hemorrhage Brief Reports
Conclusions— A threshold higher than 10.4 mL seems to be reliable to avoid error of total hematoma volume measurement in a broad range of patients. An absolute ICH volume increase of >6 mL, commonly used as outcome in ICH studies, seems well above MDD and, therefore, could be used to reliably detect ICH expansion.

Significance of Cerebral Small-Vessel Disease in Acute Intracerebral Hemorrhage Clinical Sciences
Conclusions— Preexisting cerebral SVD manifestations of WML and brain atrophy predict poor outcome in acute intracerebral hemorrhage. There is no apparent hazard of early intensive lowering of blood pressure according to the INTERACT2 protocol, in patients with underlying cerebral SVD.

Thrombus Permeability Is Associated With Improved Functional Outcome and Recanalization in Patients With Ischemic Stroke Clinical Sciences
Conclusions— This study shows that simultaneous measurement of thrombus attenuation in noncontrast computed tomography and computed tomographic angiography allows for quantification of thrombus perviousness. Thrombus perviousness is strongly associated with improved functional outcome, smaller final infarct volume, and higher recanalization rate.
