Stroke of Genius

Internationally renowned stroke clinical researcher, Conjoint Professor Chris Levi is on a medical mission: "Cure more, improve more, harm less".

Working on more than eight ground-breaking research projects improving stroke treatment options for patients, Professor Levi is on target to meet his goal, launching what he has described as "the most important acute stroke trial globally".

A clot-busting drug, Tenecteplase (TNK) will be trialled at 50 major hospitals around the world. Its potential to cure stroke in some patients has earned TNK the nickname 'The New Kid' on the stroke block.

Professor Levi and fellow University of Newcastle researcher Professor Mark Parsons, are the principal investigators on this global acute stroke trial.

"One in six people will experience a stroke in their lifetime. In Australia alone, there are 50,000 strokes every year - enough to fill the Sydney Cricket Ground," Professor Levi said.

"TNK is a clot-dissolving drug developed by industry and derived from a naturally occurring protein from the blood vessel wall. The trial will test TNK against the current standard clot-busting drug Alteplase," he said.

"Alteplase is good if it works. However, we need better, more effective and safer treatments.  Alteplase carries a small, but significant, risk of bleeding and only dissolves the clot in 30-40% of cases. TNK in Phase 2 Trial looks considerably better. We saw patients affected by stroke making almost miraculous recoveries on TNK."

Published in the prestigious New England Journal of Medicine, findings from Phase 2 Trial showed that two-thirds of patients treated with TNK displayed major improvement within 24 hours, and 72 per cent showed excellent recovery within three months after their stroke.

The TNK Phase 3 Trial begins in Australia and New Zealand in February 2014 and in Europe and Asia in mid-2014.

Australia's No 1 cause of disability 

Following his arrival at the University of Newcastle in 1999 to establish the Hunter Medical Research Institute (HMRI) Stroke Research Group, Professor Levi led the group to its current position, recognised globally as one of the leading teams for stroke research in imaging, clinical trials, health systems research and stroke genetics. Professor Levi is also the Director of the University of Newcastle's Priority Research Centre for Translational Neuroscience and Mental Health.

"Ten thousand people die from stroke each year in Australia. A quarter of those people are aged under 55," Professor Levi said.

"Death is one thing, disability is another. With 20,000 people left disabled by stroke in Australia, it's a major problem and the number one cause of disability. It is truly sad to see the impact of stroke on the patients and their families and communities.

"Frustration has been my driver. As a clinician, not being able to do enough for my patients or knowing that our health systems could be better is what drives me in research. The problem stares me in the face every day. "

Stroke of genes 

Part of a team of researchers from the University of Newcastle credited with making a major genetic discovery in stroke, Professor Levi said the future is in tailored medical care.

"We're using genetics to unravel the complex biology of the brain and to see if it can give us a clue to pre-determining factors of stroke," Professor Levi said.

Published in Nature Genetics in 2012, the discovery of the signal located within a regulatory DNA on Chromosome 6 (6p21.1) is strongly associated with large artery atherosclerotic stroke, which represent one quarter of acute strokes.

"We don't know very much about the genetics of stroke as yet. It's a very complex disease genetically, influenced by many genes and environmental factors. Most of these genetic factors are unknown but once we learn enough about them we'll be able to better profile people and advise if they are at risk of stroke."

Part of an International Stroke Genetics Consortium, Meta-Stroke, Professor Levi and his team are also collecting samples from patients with acute stroke, investigating genetic factors that could influence responsiveness to clot-busting treatment. 

"It's not just about whether you will have a stroke, we're also looking at how well you might do after a stroke and what treatment plan might work best for you."

"The body's enzyme systems are all under genetic control. Our genes basically set the plan for all of our body function and drugs. Pharmacological agents are influenced in both their efficacy and their safety by our enzyme systems in our body, which are influenced by our genes."

Setting the standard for stroke care

Professor Levi's drive and stellar reputation led him to being selected by the Australian Government to help set the upcoming national standards for treatment for stroke patients, as part of the Australian Commission for Quality and Safety in Health Care Clinical Standards and Indicators Group.  

"We're moving into an era in stroke medicine where it will be treatment tailored to the patient. Why? It's because every stroke is a bit different, every cause is a little different and it's not a one-size-fits-all-situation," Professor Levi said.

"Alteplase has been guideline approved for years, it's been out there on the market, but the proportion of stroke patients that get access to it across the country is only about five per cent. It should be in the order of 20 to 25 per cent.

"The Newcastle health system has been re-engineered over the past seven years so that 20 to 30 per cent are receiving clot-busting drugs within the 4.5 hour treatment window. We have achieved this through a number of initiatives."

Working with Stroke Awareness, Professor Levi's team has been promoting the FAST: Face, Arms, Speech and Time to call 000 message to raise community awareness of the signs of stroke and the importance of acting quickly to get treatment.

At the next stage, a Pre-hospital Acute Stroke Triage (PAST) program was introduced to both metropolitan and rural regions establishing systems to improve pre-hospital care and enhance access to clot-busting drugs. Techniques included bypass of smaller hospitals, helicopter transfer where needed, ambulance guidelines and cutting red tape. The system was introduced in the Hunter Region in 2007 and in 2013 was adopted across the state of New South Wales.

In the stroke of time

Professor Levi is also involved in two health systems studies, one aiming to improve diagnosis and treatment of transient ischaemic attack and minor stroke patients in general practices and hospitals, the other aiming to better implement clot-busting treatment.

INSIST, a National Health and Medical Research Council funded comparison study of Trans Ischemic Attacks (TIA) and minor strokes compares treatment of TIA patients from 20 different general practices in the Hunter Region to data collected by Oxford and Auckland Universities. The study assesses how GPs determine if someone is having a stroke, what happens to the patient, how they are looked after and what the long-term outcomes are.

The Thrombolysis ImPlementation in Stroke (TIPS) trial is a cluster-randomised trial that is testing strategies to boost the implementation of clot-busting drug treatment. It is testing various strategies including advanced training, education, behaviour change, executive support and more. The TIPS trial is running across 20 hospitals in QLD, NSW and Victoria.

Imaging in one stroke

The stroke research team have world leading expertise in the application of advanced CT imaging technology to acute stroke diagnosis and treatment.

Under the leadership of colleague Prof Mark Parsons, and working as a Toshiba International Luminary Site, the group have pioneered how brain perfusion imaging can better select individual patients for clot-busting treatment by identifying how much brain tissue remains viable at different time points after the onset of stroke.

The imaging analysis techniques and their applications are a world-first. Professor Levi is also investigating how combining CT imaging and ultrasound (fusion ultrasound) can be used to determine precisely when a clot has been dissolved and a blocked artery opens.

Professor Levi credits the integrated health care system in operation between the local community, John Hunter and Mater Hospitals, HMRI and the University as key to his group's success across many areas of stroke research. The various national, international and local research networks they have built is another reason for their achievements.

"Across the University and medical sector, we have people working with the Stroke Research Group in cognitive issues and depression post-stroke, imaging, nutrition, physical activity and more."

"By working together in an integrated system, we are making huge advances. The army of people we have pooled together is helping to win the battle against this crippling condition."

Agent of change

The stroke treatments pioneered by Professor Chris Levi and his team have transformed lives and medical practice.

As a clinician, Conjoint Professor Chris Levi sees evidence of the benefits of his research every time he sends a healthy patient home. 

The internationally recognised stroke neurologist and researcher and the stroke research team at John Hunter Hospital, have driven breakthroughs in treatments and developed protocols that have vastly improved the outcomes for hundreds of stroke sufferers in the Hunter region. These approaches are now being adopted across Australia.

"For the right candidate, our treatment is dramatic – it is a cure for stroke," Levi says. "Twenty years ago, I would have said that was impossible."

Levi is the director of Acute Stroke Services at John Hunter Hospital and a co-director of the University's Centre for Translational Neuroscience and Mental Health Research.

The groundbreaking model of care developed by his team of medical researchers and clinicians combines the use of thrombolytic therapy, or 'clot-busting' drugs, with CT imaging of the brain. In suitable patients the clot-busting drug tPA can dissolve the blockage in their brain that has caused the stroke and prevent further damage. CT imaging is undertaken first to identify the areas of the brain that are salvageable.

Another integral part of the care model is a triage protocol that arms frontline health workers with the skills to identify stroke sufferers eligible for the treatment and fast track their passage to the acute stroke unit at the John Hunter Hospital. There is narrow four-and-a-half-hour window of opportunity for effective clot-busting therapy.

"By combining the treatments with our triage protocol we have improved our implementation of clot-busting therapy at John Hunter Hospital from 4 per cent of patients to over 20 per cent, which means more than 100 patients a year are receiving this therapy,'' Levi says.

"When successful, the treatment has great benefits for the patient – it can mean the difference between living dependently or independently.

"From a community perspective, it is also highly beneficial. With an estimated cost of up to $500,000 for a stroke patient with high care needs, the effective use of tPA is significantly reducing pressure on the health care budget."

Levi's stroke research group has attracted National Health and Medical Research Council grants to implement in hospitals across three states the combination of thrombolytic therapy and brain imaging. Hospitals across Sydney are also implementing the Hunter New England Health stroke treatment protocol.

Only about one third of stroke sufferers are suitable for tPA, and to receive it they must arrive at a hospital equipped to deliver the treatment within four and a half hours. The other two thirds of patients may be ineligible for a variety of reasons, including risk of excessive bleeding, past illnesses or contradictory drug treatments.

Because of this, Levi and his team are also leading research into treatments for those not eligible for thrombolytic therapy. One project is a joint study with Harbin Medical University in China, into methods of cooling the brain after a stroke.

The brain is put into hibernation, which 'buys' time for the clot to break up by itself. Researchers at Harbin are developing a helmet that works locally to cool the brain, while members of the team in Newcastle are experimenting with whole body cooling.

Newcastle researchers are also leading an international multi-centre trial of a new-generation clot-busting drug called tenecteplase or TNK, which they have shown in early trials to be more effective than alteplase or tPA.

Another exciting project is the Australian Stroke Genetics Initiative, led by Newcastle stroke researchers in collaboration with the University's Centre for Bioinformatics, Biomarker Discovery and Information-Based Medicine. Its first study, published this year in Nature Genetics, established a previously undiscovered genetic signal associated with a particular type of stroke.

"The wide range of research and the significant improvements to patient outcomes across all facets of stroke treatment verifies Newcastle's leadership role in this area," Levi says.

"Working at the nexus of stroke research and treatment, working with patients every day, spurs us on to keep moving developments from the lab and into clinical practice."

Professor Levi researches in collaboration with the Hunter Medical Research Institute's (HMRI) Brain and Mental Health Program. HMRI is a partnership between the University, the Hunter New England Local Health District and the community.

Career Summary

Biography

As a conjoint academic under a full-time Area Health Service employment contract, the encroachment of clinical management responsibilities in to research time is significant. Time has had to be devoted to establishing research infrastructure and development of capacity within the Department of Neurology to undertake and sustain research activities. It is pertinent that at the time of appointment in 1998 there was no significant research program within the Department of Neurology and no activity whatsoever in the field of stroke research. With ten years of development and growth the Stroke Research Group now attracts regular competitive grant funding. Nationally and internationally recognised senior clinical researches along with research management, brain imaging and research nurse support staff.

Involvement in state and national administrative and academic roles has assisted in supporting the growth of the Newcastle Stroke Research Group at the expense of additional time pressures on research productivity. As director of the Hunter Medical Research Institute/University of Newcastle Priority Centre for Brain and Mental Health Research, Professor Levi oversees the Stroke Research Program along with programs investigating schizophrenia, affective and addictive disorders, pain and sensory disorders, ageing and cognition and models of care for mental illness. The Stroke Research program, which he estabished now supports 25 staff, including two post-doctoral stroke neurologists, two Australian Research Council Future Fellows, six current PhD students, two Honours students and one B Med Science student. Professor Levi oversees a broad portfolio of stroke research within his group ranging across animal modelling of stroke, epidemiological and observational studies, phase 2 and phase 3 clinical trials, through to population surveillance of stroke events.

His direct leadership and research activity is focused on the areas of clinical trials in acute stroke, stroke genetics, advanced acute imaging, and cluster randomised trials focusing on implementation of evidence-based stroke care. He founded the Australian Stroke Genetics Collaborative to conduct large scale national research into candidate genes to target for stroke prevention in the thrombolytic system. This research is supported by the award of a $1.3m NHMRC project grant. He has been a chief investigator and steering committee member on six NHMRC-funded randomised trials of stroke interventions over the past 10 years. He was principal investigator on the recently completed NHMRC-funded national multicentre phase 3 clinical trial Dextran In Carotid Endarterectomy (DICE), which concluded that the drug Dextran administered intravenously reduces embolic signals within three hours of carotid surgery. He was also chief investigator and steering committee member on the National Heart Foundation and NHMRC-funded acute stroke thrombolysis trial known as EPITHET (Echoplanar Imaging Thrombolytic Evaluation Trial) which evaluated the use of MRI scanning in patient selection for acute stroke treatment. A further recent study is evaluating the efficacy of a new generation “clot-busting” drug tenecteplase or TNK which looks likely to proceed to Phase 3 clinical trials. All this research, which has resulted in over 115 peer-reviewed publications in leading international journals, reflects Professor Levi’s goal of translating results into improved clinical practice. Professor Levi’s dedication to bridging the gap between research the real world is also reflected in his heavy community commitments including a five year administrative appointment as medical director of the National Stroke Foundation (NSF) and remains a member of the NSF Clinical Council. He sat on the NHMRC Project Grant Review Panels in 2008/2009 and will again sit in 2011.

Objectives: We hypothesized that common variants in the collagen genes COL4A1/COL4A2 are associated with sporadic forms of cerebral small vessel disease. Methods: We conducted meta-analyses of existing genotype data among individuals of European ancestry to determine associations of 1,070 common single nucleotide polymorphisms (SNPs) in the COL4A1/COL4A2 genomic region with the following: intracerebral hemorrhage and its subtypes (deep, lobar) (1,545 cases, 1,485 controls); ischemic stroke and its subtypes (cardioembolic, large vessel disease, lacunar) (12,389 cases, 62,004 controls); and white matter hyperintensities (2,733 individuals with ischemic stroke and 9,361 from population-based cohorts with brain MRI data). We calculated a statistical significance threshold that accounted for multiple testing and linkage disequilibrium between SNPs (p < 0.000084). Results: Three intronic SNPs in COL4A2 were significantly associated with deep intracerebral hemorrhage (lead SNP odds ratio [OR] 1.29, 95% confidence interval [CI] 1.14-1.46, p = 0.00003; r2 > 0.9 between SNPs). Although SNPs associated with deep intracerebral hemorrhage did not reach our significance threshold for association with lacunar ischemic stroke (lead SNP OR 1.10, 95% CI 1.03-1.18, p = 0.0073), and with white matter hyperintensity volume in symptomatic ischemic stroke patients (lead SNP OR 1.07, 95% CI 1.01-1.13, p = 0.016), the direction of association was the same. There was no convincing evidence of association with white matter hyperintensities in population-based studies or with non-small vessel disease cerebrovascular phenotypes. Conclusions: Our results indicate an association between common variation in the COL4A2 gene and symptomatic small vessel disease, particularly deep intracerebral hemorrhage. These findings merit replication studies, including in ethnic groups of non-European ancestry.

Background: Trials of endovascular therapy for ischemic stroke have produced variable results. We conducted this study to test whether more advanced imaging selection, recently developed devices, and earlier intervention improve outcomes. Methods: We randomly assigned patients with ischemic stroke who were receiving 0.9 mg of alteplase per kilogram of body weight less than 4.5 hours after the onset of ischemic stroke either to undergo endovascular thrombectomy with the Solitaire FR (Flow Restoration) stent retriever or to continue receiving alteplase alone. All the patients had occlusion of the internal carotid or middle cerebral artery and evidence of salvageable brain tissue and ischemic core of less than 70 ml on computed tomographic (CT) perfusion imaging. The coprimary outcomes were reperfusion at 24 hours and early neurologic improvement (.8-point reduction on the National Institutes of Health Stroke Scale or a score of 0 or 1 at day 3). Secondary outcomes included the functional score on the modified Rankin scale at 90 days. Results: The trial was stopped early because of efficacy after 70 patients had undergone randomization (35 patients in each group). The percentage of ischemic territory that had undergone reperfusion at 24 hours was greater in the endovascular-therapy group than in the alteplase-only group (median, 100% vs. 37%; P<0.001). Endovascular therapy, initiated at a median of 210 minutes after the onset of stroke, increased early neurologic improvement at 3 days (80% vs. 37%, P = 0.002) and improved the functional outcome at 90 days, with more patients achieving functional independence (score of 0 to 2 on the modified Rankin scale, 71% vs. 40%; P = 0.01). There were no significant differences in rates of death or symptomatic intracerebral hemorrhage. Conclusions: In patients with ischemic stroke with a proximal cerebral arterial occlusion and salvageable tissue on CT perfusion imaging, early thrombectomy with the Solitaire FR stent retriever, as compared with alteplase alone, improved reperfusion, early neurologic recovery, and functional outcome.

Objectives: Concussion remains one of the inherent risks of participation in rugby league. While other injuries incurred by rugby league players have been well studied, less focus and attention has been directed towards concussion. Review method: The current review examined all articles published in English from 1900 up to June 2013 pertaining to concussion in rugby league players. Data sources: Publications were retrieved via six databases using the key search terms: rugby league, league, football; in combination with injury terms: athletic injuries, concussion, sports concussion, sports-related concussion, brain concussion, brain injury, brain injuries, mild traumatic brain injury, mTBI, traumatic brain injury, TBI, craniocerebral trauma, head injury and brain damage. Observational, cohort, correlational, cross-sectional and longitudinal studies were all included. Results: 199 rugby league injury publications were identified. 39 (20%) were related in some way to concussion. Of the 39 identified articles, 6 (15%) had the main aim of evaluating concussion, while the other 33 reported on concussion incidence as part of overall injury data analyses. Rugby league concussion incidence rates vary widely from 0.0 to 40.0/1000 playing hours, depending on the definition of injury (time loss vs no time loss). The incidence rates vary across match play versus training session, seasons (winter vs summer) and playing position (forwards vs backs). The ball carrier has been found to be at greater risk for injury than tacklers. Concussion accounts for 29% of all injuries associated with illegal play, but only 9% of injuries sustained in legal play. Conclusions: In comparison with other collision sports, research evaluating concussion in rugby league is limited. With such limited published rugby league data, there are many aspects of concussion that require attention, and future research may be directed towards these unanswered questions.

Background: Perfusion computed tomography is becoming more widely used as a clinical imaging tool to predict potentially salvageable tissue (ischemic penumbra) after ischemic stroke and guide reperfusion therapies. Aims: The study aims to determine whether there are important changes in perfusion computed tomography thresholds defining ischemic penumbra and infarct core over time following stroke. Methods: Permanent middle cerebral artery occlusion was performed in adult outbred Wistar rats (n=6) and serial perfusion computed tomography scans were taken every 30 mins for 2h. To define infarction thresholds at 1h and 2h post-stroke, separate groups of rats underwent 1h (n=6) and 2h (n=6) of middle cerebral artery occlusion followed by reperfusion. Infarct volumes were defined by histology at 24h. Co-registration with perfusion computed tomography maps (cerebral blood flow, cerebral blood volume, and mean transit time) permitted pixel-based analysis of thresholds defining infarction, using receiver operating characteristic curves. Results: Relative cerebral blood flow was the perfusion computed tomography parameter that most accurately predicted penumbra (area under the curve=0·698) and also infarct core (area under the curve=0·750). A relative cerebral blood flow threshold of <75% of mean contralateral cerebral blood flow most accurately predicted penumbral tissue at 0·5h (area under the curve=0·660), 1h (area under the curve=0·659), 1·5h (area under the curve=0·636), and 2h (area under the curve=0·664) after stroke onset. A relative cerebral blood flow threshold of <55% of mean contralateral most accurately predicted infarct core at 1h (area under the curve=0·765) and at 2h (area under the curve=0·689) after middle cerebral artery occlusion. Conclusions: The data provide perfusion computed tomography defined relative cerebral blood flow thresholds for infarct core and ischemic penumbra within the first two hours after experimental stroke in rats. These thresholds were shown to be stable to define the volume of infarct core and penumbra within this time window.

Background: Stroke is a leading cause of death and disability internationally. One of the three effective interventions in the acute phase of stroke care is thrombolytic therapy with tissue plasminogen activator (tPA), if given within 4.5 hours of onset to appropriate cases of ischaemic stroke.Objectives: To test the effectiveness of a multi-component multidisciplinary collaborative approach compared to usual care as a strategy for increasing thrombolysis rates for all stroke patients at intervention hospitals, while maintaining accepted benchmarks for low rates of intracranial haemorrhage and high rates of functional outcomes for both groups at three months.Methods and design: A cluster randomised controlled trial of 20 hospitals across 3 Australian states with 2 groups: multi- component multidisciplinary collaborative intervention as the experimental group and usual care as the control group. The intervention is based on behavioural theory and analysis of the steps, roles and barriers relating to rapid assessment for thrombolysis eligibility; it involves a comprehensive range of strategies addressing individual-level and system-level change at each site. The primary outcome is the difference in tPA rates between the two groups post-intervention. The secondary outcome is the proportion of tPA treated patients in both groups with good functional outcomes (modified Rankin Score (mRS <2) and the proportion with intracranial haemorrhage (mRS =2), compared to international benchmarks.Discussion: TIPS will trial a comprehensive, multi-component and multidisciplinary collaborative approach to improving thrombolysis rates at multiple sites. The trial has the potential to identify methods for optimal care which can be implemented for stroke patients during the acute phase. Study findings will include barriers and solutions to effective thrombolysis implementation and trial outcomes will be published whether significant or not.Trial registration: Australian New Zealand Clinical Trials Registry: ACTRN12613000939796. © 2014 Paul et al.; licensee BioMed Central Ltd.

Background and Purpose-Ischemic stroke (IS) and coronary artery disease (CAD) share several risk factors and each has a substantial heritability. We conducted a genome-wide analysis to evaluate the extent of shared genetic determination of the two diseases. Methods-Genome-wide association data were obtained from the METASTROKE, Coronary Artery Disease Genomewide Replication and Meta-analysis (CARDIoGRAM), and Coronary Artery Disease (C4D) Genetics consortia. We first analyzed common variants reaching a nominal threshold of significance (P<0.01) for CAD for their association with IS and vice versa. We then examined specific overlap across phenotypes for variants that reached a high threshold of significance. Finally, we conducted a joint meta-analysis on the combined phenotype of IS or CAD. Corresponding analyses were performed restricted to the 2167 individuals with the ischemic large artery stroke (LAS) subtype. Results-Common variants associated with CAD at P<0.01 were associated with a significant excess risk for IS and for LAS and vice versa. Among the 42 known genome-wide significant loci for CAD, 3 and 5 loci were significantly associated with IS and LAS, respectively. In the joint meta-analyses, 15 loci passed genome-wide significance (P<5×10-8) for the combined phenotype of IS or CAD and 17 loci passed genome-wide significance for LAS or CAD. Because these loci had prior evidence for genome-wide significance for CAD, we specifically analyzed the respective signals for IS and LAS and found evidence for association at chr12q24/SH2B3 (PIS=1.62×10-7) and ABO (PIS=2.6×10-4), as well as at HDAC9 (PLAS=2.32×10-12), 9p21 (PLAS=3.70×10-6), RAI1-PEMT-RASD1 (PLAS=2.69×10-5), EDNRA (PLAS=7.29×10-4), and CYP17A1-CNNM2-NT5C2 (PLAS=4.9×10-4). Conclusions-Our results demonstrate substantial overlap in the genetic risk of IS and particularly the LAS subtype with CAD. © 2013 American Heart Association, Inc.

Background and Purpose - Genome-wide association studies have revealed multiple common variants associated with known risk factors for ischemic stroke (IS). However, their aggregate effect on risk is uncertain. We aimed to generate a multilocus genetic risk score (GRS) for IS based on genome-wide association studies data from clinical-based samples and to establish its external validity in prospective population-based cohorts. Methods - Three thousand five hundred forty-eight clinic-based IS cases and 6399 controls from the Wellcome Trust Case Control Consortium 2 were used for derivation of the GRS. Subjects from the METASTROKE consortium served as a replication sample. The validation sample consisted of 22 751 participants from the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium. We selected variants that had reached genome-wide significance in previous association studies on established risk factors for IS. Results - A combined GRS for atrial fibrillation, coronary artery disease, hypertension, and systolic blood pressure significantly associated with IS both in the case-control samples and in the prospective population-based studies. Subjects in the top quintile of the combined GRS had >2-fold increased risk of IS compared with subjects in the lowest quintile. Addition of the combined GRS to a simple model based on sex significantly improved the prediction of IS in the combined clinic-based samples but not in the population-based studies, and there was no significant improvement in net reclassification. Conclusions - A multilocus GRS based on common variants for established cardiovascular risk factors was significantly associated with IS both in clinic-based samples and in the general population. However, the improvement in clinical risk prediction was found to be small. © 2014 American Heart Association, Inc.

BACKGROUND AND PURPOSE-: Severe atherosclerosis in the aortic arch is associated with a high risk of recurrent vascular events, but the optimal antithrombotic strategy is unclear. METHODS-: This prospective randomized controlled, open-labeled trial, with blinded end point evaluation (PROBE design) tested superiority of aspirin 75 to 150 mg/d plus clopidogrel 75 mg/d (A+C) over warfarin therapy (international normalized ratio 2-3) in patients with ischemic stroke, transient ischemic attack, or peripheral embolism with plaque in the thoracic aorta >4 mm and no other identified embolic source. The primary end point included cerebral infarction, myocardial infarction, peripheral embolism, vascular death, or intracranial hemorrhage. Follow-up visits occurred at 1 month and then every 4 months post randomization. RESULTS-: The trial was stopped after 349 patients were randomized during a period of 8 years and 3 months. After a median follow-up of 3.4 years, the primary end point occurred in 7.6% (13/172) and 11.3% (20/177) of patients on A+C and on warfarin, respectively (log-rank, P=0.2). The adjusted hazard ratio was 0.76 (95% confidence interval, 0.36-1.61; P=0.5). Major hemorrhages including intracranial hemorrhages occurred in 4 and 6 patients in the A+C and warfarin groups, respectively. Vascular deaths occurred in 0 patients in A+C arm compared with 6 (3.4%) patients in the warfarin arm (log-rank, P=0.013). Time in therapeutic range (67% of the time for international normalized ratio 2-3) analysis by tertiles showed no significant differences across groups. CONCLUSIONS-: Because of lack of power, this trial was inconclusive and results should be taken as hypothesis generating. © 2014 American Heart Association, Inc.

Background and Purpose: Magnetic resonance perfusion (MRP) and computed tomographic perfusion (CTP) are being increasingly applied in acute stroke trials and clinical practice, yet the comparability of their perfusion values is not well validated. The aim of this study was to validate the comparability of CTP and MRP measures. METHODS-: A 3-step approach was used. Step 1 was a derivation step, where we analyzed 45 patients with acute ischemic stroke who had both CTP and MRP performed within 2 hours of each other and within 9 hours of stroke onset. In this step, we derived the optimal perfusion map with the least difference between MRP and CTP. In step 2, the optimal map was validated on whole-brain perfusion data of 15 patients. Step 3 was to apply the optimal perfusion map to define cross-modality reperfusion from acute CTP to 24-hour MRP in 45 patients and, in turn, to assess how accurately this predicted 3-month clinical outcome. RESULTS-: Among 8 different perfusion maps included in this study, time to peak of the residual function (Tmax) was the only one with a nonsignificant difference between CTP and MRP in delineating perfusion defects. This was validated on whole-brain perfusion data, showing high concordance of Tmax between the 2 modalities (concordance correlation coefficient of Lin, >0.91); the best concordance was at 6 s. At T max>6 s threshold, MRP and CTP reached substantial agreement in mismatch classification (¿ >0.61). Cross-modality reperfusion calculated by Tmax>6 s strongly predicted good functional outcome at 3 months (area under the curve, 0.979; P<0.05). CONCLUSIONS-: MRP and CTP can be used interchangeably if one uses Tmax measurement. © 2014 American Heart Association, Inc.

Background: The currently proven time window for thrombolysis in ischemic stroke is 4·5h. Beyond this, the risks and benefits of thrombolysis are uncertain. Aims: To determine whether thrombolysis and reperfusion were beneficial after 4·5h, we examined clinical and radiological outcomes in patients treated with tissue plasminogen activator or placebo within 4·5-6h, using data from the Echoplanar Imaging Thrombolytic Evaluation Trial. Methods: In the Echoplanar Imaging Thrombolytic Evaluation Trial, ischemic stroke patients presenting three to six-hours after stroke onset were randomized to tissue plasminogen activator or placebo, without knowledge of magnetic resonance imaging results. This analysis was restricted to patients treated between 4·5 and 6h. The effect of tissue plasminogen activator and reperfusion on infarct growth between baseline diffusion-weighted imaging and day 90 T2 imaging was assessed, along with good neurological outcome (=8 point reduction or reaching 0-1 at 90 days on National Institutes of Health Stroke Scale) and functional outcome (modified Rankin scale). The effect of tissue plasminogen activator on reperfusion was also analyzed. Results: Sixty-nine patients were treated 4·5-6h after onset, and infarct growth was assessed in 63. Tissue plasminogen activator was associated with lower relative growth (94% vs. 168%, P=0·03) and a trend to lower absolute growth (-0·17ml versus 9·6ml, P=0·07). Reperfusion was increased in the tissue plasminogen activator group (58% versus 25%, P=0·03) and was associated with increased rates of good neurological (86% versus 28% P<0·001) and functional (modified Rankin scale 0-2 73% versus 34%, P=0·01) outcomes. Reperfusion was strongly associated with lower relative (80% versus 189%, P<0·001) and absolute (-2·5ml versus 40ml, P<0·001) infarct growth. Conclusions: Thrombolysis 4·5-6h after stroke onset reduced infarct growth and increased the rate of reperfusion, which was associated with good neurological and functional outcome. © 2013 World Stroke Organization.

Background and Aims: Providing evidence-based clinical care reduces disability and mortality rates following stroke. We examined if compliance with evidence-based processes of care were different for patients with intracerebral haemorrhage when compared with ischemic stroke and sought to describe differences in health outcomes during hospitalization and at time of discharge for these stroke subtypes. Methods: The New South Wales acute stroke dataset was used. This included data from 50-100 consecutively admitted patients' medical records collected from 32 New South Wales hospitals between 2003 and 2010. Multivariable logistic regression analyses were conducted taking into account patient factors and clustering of patients by hospital. Results: Ischemic stroke and intracerebral haemorrhage cases had similar demographic features (ischemic stroke n=3467, mean age 74 years [standard deviation 13], 50% female; intracerebral haemorrhage n=275, mean age 74 years [standard deviation 13], 48% female). Following multivariable analyses patients with intracerebral haemorrhage were less likely to be admitted to a stroke unit (adjusted odds ratio 0·65; 95% confidence interval 0·45-0·94) or receive an assessment from allied health (adjusted odds ratio 0·54; 95% confidence interval 0·33-0·89) than patients with ischemic stroke. Patients with intracerebral haemorrhage are also less likely to be independent (adjusted odds ratio 0·36; 95% confidence interval 0·3-0·5) at time of hospital discharge and had a greater odds of dying in hospital (adjusted odds ratio 2·1; 95% confidence interval 1·3-3·5). Patients that were admitted to a stroke unit had a greater odds of being independent (modified Rankin Score 0-2) at day 7-10 irrespective of stroke type or severity on admission (adjusted odds ratio 1·3; 95% confidence interval 1·01-1·66). Conclusions: Following intracerebral haemorrhage, patients were less likely to be admitted to an acute stroke unit and receive allied health interventions. Admission to stroke units improved the likelihood of being independent at days 7-10 and, therefore, more should be done to encourage evidence-based care for intracerebral haemorrhage. © 2013 World Stroke Organization.

Background: Intracranial pressure elevation, peaking three to seven post-stroke is well recognized following large strokes. Data following small-moderate stroke are limited. Therapeutic hypothermia improves outcome after cardiac arrest, is strongly neuroprotective in experimental stroke, and is under clinical trial in stroke. Hypothermia lowers elevated intracranial pressure; however, rebound intracranial pressure elevation and neurological deterioration may occur during rewarming. Hypotheses: (1) Intracranial pressure increases 24h after moderate and small strokes. (2) Short-duration hypothermia-rewarming, instituted before intracranial pressure elevation, prevents this 24h intracranial pressure elevation. Methods: Long-Evans rats with two hour middle cerebral artery occlusion or outbred Wistar rats with three hour middle cerebral artery occlusion had intracranial pressure measured at baseline and 24h. Wistars were randomized to 2·5h hypothermia (32·5°C) or normothermia, commencing 1h after stroke. Results: In Long-Evans rats (n=5), intracranial pressure increased from 10·9±4·6mmHg at baseline to 32·4±11·4mmHg at 24h, infarct volume was 84·3±15·9mm3. In normothermic Wistars (n=10), intracranial pressure increased from 6·7±2·3mmHg to 31·6±9·3mmHg, infarct volume was 31·3±18·4mm3. In hypothermia-treated Wistars (n=10), 24h intracranial pressure did not increase (7·0±2·8mmHg, P<0·001 vs. normothermia), and infarct volume was smaller (15·4±11·8mm3, P<0·05). Conclusions: We saw major intracranial pressure elevation 24h after stroke in two rat strains, even after small strokes. Short-duration hypothermia prevented the intracranial pressure rise, an effect sustained for at least 18h after rewarming. The findings have potentially important implications for design of future clinical trials. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

Background: Our randomized controlled trial of a multifaceted evidence-based intervention for improving the inpatient management of fever, hyperglycemia, and swallowing dysfunction in the first three-days following stroke improved outcomes at 90 days by 15%. We designed a quantitative process evaluation to further explain and illuminate this finding. Methods: Blinded retrospective medical record audits were undertaken for patients from 19 stroke units prior to and following the implementation of three multidisciplinary evidence-based protocols (supported by team-building workshops, and site-based education and support) for the management of fever (temperature =37·5°C), hyperglycemia (glucose >11mmol/l), and swallowing dysfunction in intervention stroke units. Results: Data from 1804 patients (718 preintervention; 1086 postintervention) showed that significantly more patients admitted to hospitals allocated to the intervention group received care according to the fever (n=186 of 603, 31% vs. n=74 of 483, 15%, P<0·001), hyperglycemia (n=22 of 603, 3·7% vs. n=3 of 483, 0·6%, P=0·01), and swallowing dysfunction protocols (n=241 of 603, 40% vs. n=19 of 483, 4·0%, P=0·001). Significantly more patients in these intervention stroke units received four-hourly temperature monitoring (n=222 of 603, 37% vs. n=90 of 483, 19%, P<0·001) and six-hourly glucose monitoring (194 of 603, 32% vs. 46 of 483, 9·5%, P<0·001) within 72 hours of admission to a stroke unit, and a swallowing screen (242 of 522, 46% vs. 24 of 350, 6·8%, P=0·0001) within the first 24 hours of admission to hospital. There was no difference between the groups in the treatment of patients with fever with paracetamol (22 of 105, 21% vs. 38 of 131, 29%, P=0·78) or their hyperglycemia with insulin (40 of 100, 40% vs. 17 of 57, 30%, P=0·49). Interpretation: Our intervention resulted in better protocol adherence in intervention stroke units, which explains our main trial findings of improved patient 90-day outcomes. Although monitoring practices significantly improved, there was no difference between the groups in the treatment of fever and hyperglycemia following acute stroke. A significant link between improved treatment practices and improved outcomes would have explained further the success of our intervention, and we are still unable to explain definitively the large improvements in death and dependency found in the main trial results. One potential explanation is that improved monitoring may have led to better overall surveillance of deteriorating patients and faster initiation of treatments not measured as part of the main trial. © 2013 World Stroke Organization.

Results: In an overall analysis of 17,970 cases of ischemic stroke and 70,764 controls, we identified a novel association on chromosome 12q24 (rs10744777, odds ratio [OR] 1.10 [1.07-1.13], p 5 7.12 3 10-11) with ischemic stroke. The association was with all ischemic stroke rather than an individual stroke subtype, with similar effect sizes seen in different stroke subtypes. There was no association with intracerebral hemorrhage (OR 1.03 [0.90-1.17], p 5 0.695).

BACKGROUND AND PURPOSE - : Studies in rodent models suggest that upregulating angiopoietin-1 (Angpt1) improves stroke outcomes. The aims of this study were to assess the association of plasma Angpt1 with stroke occurrence and outcome. METHODS - : Plasma Angpt1 was measured in 336 patients who had experienced a recent stroke and 321 healthy controls with no stroke history. Patients with stroke (n=285) were reassessed at 3 months and plasma Angpt1 concentration on admission compared between those with severe and minor disability as assessed by the modified Rankin scale. In a separate cohort of 4032 community-acquired older men prospectively followed for a minimum of 6 years, the association of plasma Angpt1 with stroke incidence was examined. RESULTS - : Median plasma Angpt1 was 3-fold lower in patients who had experienced a recent stroke (6.42, interquartile range, 4.26-9.53 compared with 17.36; interquartile range, 14.01-22.46 ng/mL; P<0.001) and remained associated with stroke after adjustment for other risk factors. Plasma Angpt1 concentrations on admission were lower in patients who had severe disability or died at 3 months (median, 5.52; interquartile range, 3.81-8.75 ng/mL for modified Rankin scale 3-6; n=91) compared with those with minor disability (median, 7.04; interquartile range, 4.75-9.92 ng/mL for modified Rankin scale 0-2; n=194), P=0.012, and remained negatively associated with severe disability or death after adjusting for other risk factors. Plasma Angpt1 was not predictive of stroke incidence in community-dwelling older men. CONCLUSIONS - : Plasma Angpt1 concentrations are low after ischemic stroke particularly in patients with poor stroke outcomes at 3 months. Interventions effective at upregulating Angpt1 could potentially improve stroke outcomes. © 2014 American Heart Association, Inc.

2014Gardner A, Iverson GL, Levi CR, Schofield PW, Kay-Lambkin F, Kohler RMN, Stanwell P, 'A systematic review of concussion in rugby league', British Journal of Sports Medicine, (2014)

Objectives Concussion remains one of the inherent risks of participation in rugby league. While other injuries incurred by rugby league players have been well studied, less focus and attention has been directed towards concussion. Review method The current review examined all articles published in English from 1900 up to June 2013 pertaining to concussion in rugby league players. Data sources Publications were retrieved via six databases using the key search terms: rugby league, league, football; in combination with injury terms: athletic injuries, concussion, sports concussion, sports-related concussion, brain concussion, brain injury, brain injuries, mild traumatic brain injury, mTBI, traumatic brain injury, TBI, craniocerebral trauma, head injury and brain damage. Observational, cohort, correlational, cross-sectional and longitudinal studies were all included. Results 199 rugby league injury publications were identified. 39 (20%) were related in some way to concussion. Of the 39 identified articles, 6 (15%) had the main aim of evaluating concussion, while the other 33 reported on concussion incidence as part of overall injury data analyses. Rugby league concussion incidence rates vary widely from 0.0 to 40.0/1000 playing hours, depending on the definition of injury (time loss vs no time loss). The incidence rates vary across match play versus training session, seasons (winter vs summer) and playing position (forwards vs backs). The ball carrier has been found to be at greater risk for injury than tacklers. Concussion accounts for 29% of all injuries associated with illegal play, but only 9% of injuries sustained in legal play. Conclusions In comparison with other collision sports, research evaluating concussion in rugby league is limited. With such limited published rugby league data, there are many aspects of concussion that require attention, and future research may be directed towards these unanswered questions. © 2014 BMJ Publishing Group Ltd & British Association of Sport and Exercise Medicine.

Background: The Age, Blood pressure, Clinical features, Duration of symptoms, Diabetes (ABCD2) score can be used to predict early recurrent stroke risk following Transient ischemic attack (TIA). Given that recurrent stroke risk can be as high as 20% in the first week, international guidelines recommend "high-risk" TIAs (ABCD2 >3) be seen by specialist services such as dedicated acute neurovascular clinics within 24hours. The goal of this study was to examine the associations of both quality of referrals to a specialist acute clinic and of "guideline congruence" of time-to-clinic consultation after TIA/minor stroke. We hypothesized high-quality referrals containing key clinical elements would be associated with greater guideline congruence. Methods: A retrospective analysis of referrals to an acute neurovascular clinic within a tertiary care hospital of consecutive patients with TIA/minor stroke. Quality of general practitioner and emergency department referrals was defined on the basis of information content enabling ABCD2-based risk stratification by the clinic triage service. Time-to-clinic consultation was used to define "guideline congruence.". Results: Referrals of 148 consecutive eligible patients were reviewed. Sixty-six percent of cases were subsequently neurologist-diagnosed as TIA or minor stroke. Seventy-nine percent were referred by general practitioners. Fifty-three percent of referrals were of high quality, but quality was not associated with guideline congruence. Of the high-risk patients, only 3.6% were seen at the clinic within 24hours of index event and 31.3% within 24hours of referral. Conclusions: Current guidelines are pathophysiologically logical and evidence based, but are difficult toimplement. Improving quality of primary-secondary communication by improved referral quality is unlikely to improve guideline compliance. Alternativestrategies are needed to reduce recurrent stroke risk after TIA/minor stroke.

Background: Many aspects of CSF dynamics are poorly understood due to the difficulties involved in quantification and visualization. In particular, there is debate surrounding the route of CSF drainage. Our aim was to quantify CSF flow, volume, and drainage route dynamics in vivo in young and aged spontaneously hypertensive rats (SHR) using a novel contrast-enhanced computed tomography (CT) method.Methods: ICP was recorded in young (2-5 months) and aged (16 months) SHR. Contrast was administered into the lateral ventricles bilaterally and sequential CT imaging was used to visualize the entire intracranial CSF system and CSF drainage routes. A customized contrast decay software module was used to quantify CSF flow at multiple locations.Results: ICP was significantly higher in aged rats than in young rats (11.52 ± 2.36 mmHg, versus 7.04 ± 2.89 mmHg, p = 0.03). Contrast was observed throughout the entire intracranial CSF system and was seen to enter the spinal canal and cross the cribriform plate into the olfactory mucosa within 9.1 ± 6.1 and 22.2 ± 7.1 minutes, respectively. No contrast was observed adjacent to the sagittal sinus. There were no significant differences between young and aged rats in either contrast distribution times or CSF flow rates. Mean flow rates (combined young and aged) were 3.0 ± 1.5 µL/min at the cerebral aqueduct; 3.5 ± 1.4 µL/min at the 3rd ventric= and 2.8 ± 0.9 µL/min at the 4th ventricle. Intracranial CSF volumes (and as percentage total brain volume) were 204 ± 97 µL (8.8 ± 4.3%) in the young and 275 ± 35 µL (10.8 ± 1.9%) in the aged animals (NS).Conclusions: We have demonstrated a contrast-enhanced CT technique for measuring and visualising CSF dynamics in vivo. These results indicate substantial drainage of CSF via spinal and olfactory routes, but there was little evidence of drainage via sagittal sinus arachnoid granulations in either young or aged animals. The data suggests that spinal and olfactory routes are the primary routes of CSF drainage and that sagittal sinus arachnoid granulations play a minor role, even in aged rats with higher ICP. © 2014 Murtha et al.; licensee BioMed Central Ltd.

Objective: This paper identified barriers which prevent rural health care providers from utilising rt-PA in acute ischaemic stroke and proposes possible support mechanisms to increase its utilisation. Methods: This descriptive study uses data from anonymous surveys distributed to health care providers involved in acute stroke patient care in three rural hospitals with rt-PA pathways. Saturation sampling was used. Surveys gathered self assessed ratings of experience, practice environment, attitudes, existing support, barriers and possible enablers regarding rt-PA use in acute stroke. Results: Physicians reported the strongest barriers to the use of rt-PA in acute stroke as pre-hospital delays (91%), risk of intracerebral haemorrhage (ICH) (73%) and clinical diagnostic uncertainty (60%). They reported high levels of confidence in the support received from their stroke units (90%). Nurses identified a poor level of stroke education and knowledge on rt-PA utilisation in acute stroke. A third of nurses could correctly list six different stroke signs. The risk of ICH following rt-PA administration in stroke was also a significant barrier for nurses. Response rate from physicians was 26% (10/38) and 19% (13/69) for nurses. Conclusions: To reduce barriers to rt-PA utilisation in rural facilities physicians require education on the calculated risk of ICH as well as exposure and experience to improve their ability to confidently diagnose stroke patients who are eligible for rt-PA treatment. Education for nurses on symptoms of stroke and rt-PA utilisation and administration is recommended. © National Rural Health Alliance Inc.

Rationale: No evidence-based acute therapies exist for intracerebral hemorrhage. Intracerebral hemorrhage growth is an important determinant of patient outcome. Tranexamic acid is known to reduce hemorrhage in other conditions. Aim: The study aims to test the hypothesis that intracerebral hemorrhage patients selected with computed tomography angiography contrast extravasation 'spot sign' will have lower rates of hematoma growth when treated with intravenous tranexamic acid within 4·5-hours of stroke onset compared with placebo. Design: The Spot sign and Tranexamic acid On Preventing ICH growth - AUStralasia Trial is a multicenter, prospective, 1:1 randomized, double-blind, placebo-controlled, investigator-initiated, academic Phase II trial. Intracerebral hemorrhage patients fulfilling clinical criteria (e.g. Glasgow Coma Scale >7, intracerebral hemorrhage volume <70ml, no identified secondary cause of intracerebral hemorrhage, no thrombotic events within the previous 12 months, no planned surgery) and demonstrating contrast extravasation on computed tomography angiography will receive either intravenous tranexamic acid 1g 10-min bolus followed by 1g eight-hour infusion or placebo. A second computed tomography will be performed at 24 ± 3 hours to evaluate intracerebral hemorrhage growth and patients followed up for three-months. Study outcomes: The primary outcome measure is presence of intracerebral hemorrhage growth by 24 ± 3 hours, defined as either >33% or >6ml increase from baseline, and will be adjusted for baseline intracerebral hemorrhage volume. Secondary outcome measures include growth as a continuous measure, thromboembolic events, and the three-month modified Rankin Scale score. Discussion: This is the first trial to evaluate the efficacy of tranexamic acid in intracerebral hemorrhage patients selected based on an imaging biomarker of high likelihood of hematoma growth. The trial is registered as NCT01702636. © 2013 World Stroke Organization.

Background: Perfusion computed tomography is becoming more widely used as a clinical imaging tool to predict potentially salvageable tissue (ischemic penumbra) after ischemic stroke and guide reperfusion therapies. Aims: The study aims to determine whether there are important changes in perfusion computed tomography thresholds defining ischemic penumbra and infarct core over time following stroke. Methods: Permanent middle cerebral artery occlusion was performed in adult outbred Wistar rats (n=6) and serial perfusion computed tomography scans were taken every 30 mins for 2h. To define infarction thresholds at 1h and 2h post-stroke, separate groups of rats underwent 1h (n=6) and 2h (n=6) of middle cerebral artery occlusion followed by reperfusion. Infarct volumes were defined by histology at 24h. Co-registration with perfusion computed tomography maps (cerebral blood flow, cerebral blood volume, and mean transit time) permitted pixel-based analysis of thresholds defining infarction, using receiver operating characteristic curves. Results: Relative cerebral blood flow was the perfusion computed tomography parameter that most accurately predicted penumbra (area under the curve=0·698) and also infarct core (area under the curve=0·750). A relative cerebral blood flow threshold of <75% of mean contralateral cerebral blood flow most accurately predicted penumbral tissue at 0·5h (area under the curve=0·660), 1h (area under the curve=0·659), 1·5h (area under the curve=0·636), and 2h (area under the curve=0·664) after stroke onset. A relative cerebral blood flow threshold of <55% of mean contralateral most accurately predicted infarct core at 1h (area under the curve=0·765) and at 2h (area under the curve=0·689) after middle cerebral artery occlusion. Conclusions: The data provide perfusion computed tomography defined relative cerebral blood flow thresholds for infarct core and ischemic penumbra within the first two hours after experimental stroke in rats. These thresholds were shown to be stable to define the volume of infarct core and penumbra within this time window. © 2013 World Stroke Organization.

Background: Transient ischemic attacks and minor stroke entail considerable risk of completed stroke but this risk is reduced by prompt assessment and treatment. Risk can be stratified according to the ABCD2 prediction score. Current guidelines suggest specialist assessment and treatment within 24h for high-risk event (ABCD2 score 4-7) and seven-days for low-risk event (ABCD2 score =3). Aims: The study aims to establish paths to care and outcomes for patients referred by general practitioners and emergency departments to an Australian acute access transient ischemic attack service. Methods: This is a prospective audit. Primary outcomes were time from event to referral, from referral to clinic appointment, and from event to appointment. ABCD2 score was calculated for each event. Time from event was modeled using Cox proportional hazards regression. Results: There were 231 clinic attendees (general practitioner: 127; emergency department: 104). Mean time from event to referral was 9·2 days (SD 23·7, median 2), from referral to being seen in the clinic was 13·6 days (SD 19·0, median 7), and from event to being seen in the clinic was 17·2 days (SD 27·1, median 10). Of low-risk patients, 38·5% were seen within seven-days of event. Of high-risk patients, 36·7% were seen within one-day. ABCD2 score was not a significant predictor of any time interval from event to clinic attendance. There were no completed strokes prior to clinic attendance. Conclusions: Times from event to clinic assessment were in excess of current recommendations and risk stratification was suboptimal, though short-term outcomes were good. Improvements in referral mechanisms may enhance risk-stratification and triage. © 2013 World Stroke Organization.

Transcranial ultrasound can rapidly and non-invasively image blood flow in the major basal intracranial arteries. Its accuracy makes it acceptable for use in screening for haemodynamically significant intracranial stenoses or vessel occlusions. Although it has a relatively limited field of view and is not technically feasible in approximately 10% of cases, the information obtained is becoming increasingly relevant to therapeutic decision-making in the prevention and management of stroke. Transcranial Doppler ultrasound or transcranial colour-coded duplex have the advantages of relatively low cost, ease of repeatability, and excellent safety and tolerability, but they provide inferior spatial and anatomical detail in comparison to angiographic techniques.
