Arterial Spin Labeling Perfusion Magnetic Resonance Imaging Performed in Acute Perinatal Stroke Reveals Hyperperfusion Associated With Ischemic Injury Clinical Sciences
Conclusions— Perfusion-weighted imaging can be obtained in neonates with acute stroke and often reveals hyperperfusion in the infarct core. Penumbra in arterial ischemic stroke is seldom found. Hyperperfusion may be caused by poststroke reperfusion or to neuronal hyperexcitability of stroke-associated seizure. Its identification may be useful for consideration of therapy for acute neonatal stroke.

Extended-Release Niacin Therapy and Risk of Ischemic Stroke in Patients With Cardiovascular Disease: The Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides: Impact on Global Health Outcome (AIM-HIGH) Trial Major Clinical Trials
Conclusions— Although there were numerically more ischemic strokes with addition of ERN to simvastatin that reached nominal significance, the number was small, and multivariable analysis accounting for known risk factors did not support a significant association between niacin and ischemic stroke risk.

Minimal Clinically Important Difference for Safe and Simple Novel Acute Ischemic Stroke Therapies Clinical Sciences
Conclusions—Stroke expert responses to MCID surveys are affected by anchoring and centrality bias. When survey design takes these into account, the expert-derived MCID for a safe acute ischemic stroke treatment is 1.1% to 1.5%, in accord with actual physician behavior in guideline writing and clinical practice. This revised MCID value can guide clinical trial design and grant-funding and regulatory agency decisions.

Arterial Obstruction on Computed Tomographic or Magnetic Resonance Angiography and Response to Intravenous Thrombolytics in Ischemic Stroke Clinical Sciences
Conclusions—Intravenous thrombolytics provide benefit to stroke patients with computed tomographic angiography or magnetic resonance angiography evidence of arterial obstruction, but the sample was underpowered to demonstrate significant treatment benefit or harm among patients with apparently patent arteries.Clinical Trial Registration—URL: http://www.isrctn.com. Unique identifier: ISRCTN25765518.

Prehospital Emergency Care in Childhood Arterial Ischemic Stroke Brief Report
Background and Purpose—Immediately calling an ambulance is the key factor in reducing time to hospital presentation for adult stroke. Little is known about prehospital care in childhood arterial ischemic stroke (AIS). We aimed to determine emergency medical services call-taker and paramedic diagnostic sensitivity and to describe timelines of care in childhood AIS.Methods—This is a retrospective study of ambulance-transported children aged

Trends in Substance Abuse Preceding Stroke in Young Adults: An Update (S55.004)
Conclusions: Substance abuse is an important and highly prevalent risk factor for stroke in young adults. More efforts are needed to curb the increasing relationship between stroke in young adults and illicit drugs, alcohol, and smoking.Study supported by: NIH NINDS grant R01 NS30678Disclosure: Dr. De Los Rios La Rosa has nothing to disclose.

Orosomucoid-1 Protein Dynamics Following Ischemic Stroke in Humans and Mice (P1.265)
Conclusions:ORM-1 is a sexually dimorphic protein involved in the early (<24 hour) response to ischemic stroke. This research demonstrates that sex differences exist in post-stroke ORM-1 protein dynamics, and serves as an initial step in determining the mechanism of ORM-1 in the ischemic stroke response and its potential as a future therapeutic target for both sexes.Study Supported by:NIH Grant 5 R01 NS055215 09, and Hartford Hospital, Hartford, CT.Additional thanks to Sharon DiMauro, Lori Capozzi, and to the Scientific Research Committee at the University of Connecticut School of Medicine.Disclosure: Dr. Mistry has not...

Does Transferring Patients to Stroke Centers Increase Length of Stay (P2.313)
Conclusions: There was no difference in LOS or any clinical outcomes between the ED and transferred patients. Additionally, transferred patients did not receive more advanced procedures such as intra-arterial therapy or hemicraniectomy. Further studies exploring non-tPA patients and transient ischemic attack patients would be informative, as well as non-home, discharge location relative to the patient’s residence.Disclosure: Dr. Cossey has nothing to disclose.

Thrombolytic Utilization in Ischemic Stroke Is Significantly Higher in US Hospitals with Neurology Residency Program (S02.006)
CONCLUSIONS: Stroke care at NR hospitals is associated with an increased thrombolytic utilization rate. The increased tPA utilization at NR between 2002-2006 may be related to the rapid increase in Primary Stroke Centers across the country.Disclosure: Dr. Moradiya has nothing to disclose.

Optical Bedside Monitoring of Cerebral Blood Flow in Acute Ischemic Stroke Patients during Head of Bed Manipulation (P4.216)
CONCLUSIONS: A lower HOB angle results in an increase in cortical CBF without a significant change in arterial flow velocity in the setting of acute stroke, but there is variability across patients in this response. Bedside CBF monitoring with DCS provides a potential means to individualize interventions designed to optimize CBF in acute ischemic stroke.Disclosure: Dr. Favilla has nothing to disclose.

Safety of tPA + Transcranial Emission of Low-Energy Lasers for Acute Stroke Recovery - Results (P4.219)
Conclusion: Transcranial Laser in this small exploratory study was well tolerated in combination with IV tPA. Larger studies are needed to explore if the combination of LASER therapy plus tPA is safe and shows better outcome than IV tPA alone.Study supported by NIH Grant P50 NS044148Clinical Trial Registry: NCT01220739Disclosure: Dr. Hemmen has nothing to disclose.

Alpha 1-Antitrypsin Therapy Mitigated Ischemic Stroke Damage in Rats
Our objective is to develop a new therapy for the treatment of stroke. Currently, the only effective therapy for acute ischemic stroke is the thrombolytic agent recombinant tissue plasminogen activator. α1-Antitrypsin (AAT), a serine proteinase inhibitor with potent anti-inflammatory, anti-apoptotic, antimicrobial, and cytoprotective activities, could be beneficial in stroke. The goal of this study is to test whether AAT can improve ischemic stroke outcome in an established rat model. Middle cerebral artery occlusion was induced in male rats via intracranial (i.c.) microinjection of endothelin-1. Five to 10 minutes after...

"Worth the Walk:" A Randomized Controlled Trial of a Walking Intervention to Decrease Stroke Risk Among Minority Seniors (S51.002)
Conclusions:We successfully implemented a community-partnered, culturally-tailored, sustainable program to increase walking in minority seniors. Preliminary data analysis suggests improvement in non-sustained increases in steps/day. Next steps include more extensive data analyses, including stakeholder interviews, and examination of participant-level and organizational features associated with more successful study outcomes and program implementation.Study Supported by: - University of California, Los Angeles (UCLA) and Charles Drew University (CDU), Resource Centers for Minority Aging Research Center for Health Improvemen...
