Cerebral Microbleeds Predict Intracerebral Hemorrhage in Hemodialysis Patients Clinical Sciences
Conclusions— This study showed that the presence of CMBs was an independent and strong predictor of intracerebral hemorrhage in stroke-free hemodialysis patients, indicating that hemodialysis patients with CMBs should be carefully monitored for future onset of intracerebral hemorrhage.

Carotid Plaque Morphological Classification Compared With Biomechanical Cap Stress: Implications for a Magnetic Resonance Imaging-Based Assessment Clinical Sciences
Conclusions— Instead of trying to target only vulnerable plaques, a more reliable noninvasive identification of a select group of stable plaques with a thick cap and low stress might be a more fruitful approach to start reducing surgical interventions on carotid plaques.

Estimating Total Cerebral Microinfarct Burden From Diffusion-Weighted Imaging Clinical Sciences
Conclusions— Detecting even a single DWI lesion suggests an annual incidence of hundreds of new CMI. The cumulative effects of these lesions may directly contribute to small-vessel–related vascular cognitive impairment.

Reduction of Diffusion-Weighted Imaging Contrast of Acute Ischemic Stroke at Short Diffusion Times Clinical Sciences
Conclusions— Short diffusion times result in dramatically reduced diffusion contrast of human stroke. Simulations implicate a combination of neuronal beading and axonal swelling as the key structural changes leading to the reduced apparent diffusion coefficient after stroke.

White Matter Lesions Double the Risk of Post-Thrombolytic Intracerebral Hemorrhage Clinical Sciences
Conclusions— WMLs visible on computed tomography are associated with a more than doubled risk of sICH in patients treated with intravenous thrombolysis for acute ischemic stroke.

Therapeutically Targeting Tumor Necrosis Factor-{alpha}/Sphingosine-1-Phosphate Signaling Corrects Myogenic Reactivity in Subarachnoid Hemorrhage Basic Sciences
Conclusions— Vascular smooth muscle cell TNFα and sphingosine-1-phosphate signaling significantly enhance cerebral artery tone in SAH; anti-TNFα and anti–sphingosine-1-phosphate treatment may significantly improve clinical outcome.

Dynamic Evolution of Diffusion-Weighted Imaging Lesions in Patients With Minor Ischemic Stroke Brief Reports
Conclusions— The most common pattern of infarct evolution in patients with minor stroke is a reduction in volume, but complete resolution is uncommon.

Pediatric Acute Stroke Protocol Activation in a Children's Hospital Emergency Department Brief Reports
Conclusions— Of pediatric brain attacks, 24% were stroke, 2% were transient ischemic attack, and 14% were other neurological emergencies. Together, 40% had a stroke or other neurological emergency, underscoring the need for prompt evaluation and management of children with brain attacks.

Leukoaraiosis Burden Significantly Modulates the Association Between Infarct Volume and National Institutes of Health Stroke Scale in Ischemic Stroke Clinical Sciences
Conclusions— Leukoaraiosis significantly modulates the association between infarct volume and NIHSS. The clinical implications of these findings need further exploration in prospective studies but may be relevant to mitigate outcome differences in patients with stroke by aiding treatment decisions that rely on the NIHSS.

Relationship Between Lesion Topology and Clinical Outcome in Anterior Circulation Large Vessel Occlusions Clinical Sciences
Conclusions— Involvement of the right parieto-occipital (M6) and left superior frontal (M4) regions affect clinical outcome in anterior large vessel occlusions over and above the effect of infarct volume and should be considered during prognostication.

White Matter Damage Relates to Oxygen Saturation in Children With Sickle Cell Anemia Without Silent Cerebral Infarcts Clinical Sciences
Conclusions— These data show widespread white matter abnormalities in a sample of asymptomatic children with sickle cell anemia, and provides for the first time direct evidence of a relationship between brain microstructure and markers of disease severity (eg, peripheral oxygen saturation and steady-state hemoglobin). This study suggests that diffusion tensor imaging metrics may serve as a biomarker for future trials of reducing hypoxic exposure.
