The study was published in the journal <a href="http://www.journals.elsevier.com/free-radical-biology-and-medicine/" target="_blank"><span style="color: #800000;"><em>Free Radical Biology and Medicine</em></span></a> and the findings of this study point to a positive direction for those suffering from ALS.</strong></span></p> </div><div id="Text111" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">MitoQ is a mitochondria-targeted antioxidant created over a decade ago that reduces mitochondrial oxidative stress and, when administered to a mouse model of ALS, delayed the progression of the fatal neurodegenerative disease. Mitochondria are also known as cellular batteries and provide energy to cells.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The results of this study show a promise that mitochondria-targeted antioxidants could potentially be of use for the treatment of ALS, a condition for which there is currently no cure.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;This study supports the role of mitochondrial dysfunction in the development and progression of ALS, which may allow for the development of more mitochondria-targeted therapies to fight this disease,&rdquo; says Rafael Radi, director of the Center and a key member of the study&rsquo;s research team. &ldquo;We also found that MitoQ has beneficial effects in the murine model of ALS, which will likely lead to clinical trials using MitoQ with ALS patients and hopefully lead to extend the survival and improve the quality of life of ALS patients.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Researchers sought to decrease oxidative stress in mitochondria as a way to slow the death of motor neurons and disease progression within the ALS-induced mice. MitoQ works by accumulating inside the mitochondria and performing antioxidant activity, while allowing the molecule to act specifically at the site of free radical formation in the cells and efficiently reduce oxidative stress.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />To conduct their study, scientists administered MitoQ to the mice&rsquo;s drinking water from a time when early symptoms of neurodegeneration had become evident. After 20 days of administration, MitoQ was detected in all tested tissues and the treatment had slowed the decline of mitochondrial function in both the spinal cord and the quadriceps muscles.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;MitoQ increased approximately 6% the survival of the treated mice,&rdquo; notes Patricia Cassina, another key senior member of the research team. &ldquo;This might seem small, but it&rsquo;s in the range of the best that other drugs have been able to achieve with this model in which the disease progression is extremely fast and there is a small window of opportunity to improve symptoms and survival.&rdquo; Radi notes that MitoQ administration also resulted in improved muscular strength as evaluated by functional tests performed in the animals.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />An advantage of MitoQ is that it has been tested for safety in a variety of clinical human trials since its inception in the late 1990s. The Center of Free Radical and Biomedical Research is now evaluating the possibility of conducting clinical human trials specifically related to MitoQ and its effects on ALS patients.</span></p></div> Metactive debuts embolization technology with presentation at SIR http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/metactive-debuts-embolization-technology-with-presentation-at-sir 2014-03-24T11:14:00Z 2014-03-24T11:14:00Z <div id="ImageMain12" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/metactive-debuts-embolization-technology-with-presentation-at-sir"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/037/Nick_Franano_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction12" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Metactive Medical presented new nonclinical data on one of its investigational devices at the&nbsp;Society of Interventional Radiology&rsquo;s (SIR) Annual Scientific Meeting. The presentation focused on the company&rsquo;s device that addresses the cerebral aneurysm market.</strong></span></p> </div><div id="Text112" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The company&rsquo;s chief executive officer, F Nicholas Franano, made an oral presentation titled &ldquo;Over-the-wire Device for Immediate, Complete and Durable Occlusion of Saccular Cerebral Aneurysms&rdquo; during the &ldquo;Arterial Aneurysms and Dissection&rdquo; session at the meeting.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Endovascular embolization of cerebral aneurysms with coils was a major advance when it was introduced more than 20 years ago,&rdquo; says Franano. &ldquo;The technology that we are developing at Metactive builds upon that innovation by providing a next-generation device that has the potential to provide better patient outcomes, to be faster and easier for physicians to use, and to improve hospital profitability.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">At SIR, Metactive presented findings from a recent pilot nonclinical study in which the company&rsquo;s cerebral aneurysm embolic device demonstrated immediate and complete mechanical occlusion of a large, terminal saccular aneurysm, as well as full endothelialisation and sealing of the aneurysm neck at one month. By comparison, in the same aneurysm model, treatment using widely used conventional coils did not provide immediate and complete occlusion. Compared to coiling, the procedure to place Metactive&rsquo;s device took half as long, and the devices cost one-third as much. While Metactive has only completed a handful of nonclinical procedures to date, these excellent early results support further investigation.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;If Metactive can demonstrate that this new device can provide better clinical outcomes with much lower procedure time and complexity, and large reductions in cost, then I believe it has the potential to provide real value for patients, physicians, hospitals and payers -- especially for large aneurysms,&rdquo; says Kieran Murphy, interventional neuroradiologist and professor of radiology at the University Health Network Toronto in Ontario, Canada, and director of clinical faculty at the Techna Research Institute.</span></p></div> ADAPT a safe and simple technique for ischaemic stroke thrombectomy http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/adapt-a-safe-and-simple-technique-for-ischaemic-stroke-thrombectomy 2014-03-21T11:12:00Z 2014-03-21T11:12:00Z <div id="ImageMain13" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/adapt-a-safe-and-simple-technique-for-ischaemic-stroke-thrombectomy"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Silver5MAX_ACE_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction13" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A direct aspiration first pass technique (ADAPT) with a large bore aspiration catheter has been shown to be &ldquo;fast, safe, simple and effective method&rdquo; for acute ischaemic stroke thrombectomy.

Patients who were included in the study (98 with 100 occlusions) had large vessel, cerebral vessel occlusion with a viable penumbra and a less than one-third ischaemic vascular territory.</span></p> <p><br /><span style="font-size: 10pt;">Turk <em>et al</em> state that during the study period, the 5MAX ACE became available therefore they also compared the performance of the 5MAX ACE and the 5MAX (Penumbra).</span></p> <p><br /><span style="font-size: 10pt;">The degree of vessel occlusion was measured before and after the procedure and defined in the modified Thrombolysis and Cerebral Infarction (TICI) classification. Successful recanalisation was defined as TICI score &ge;2b post-treatment. Procedure time was classed as from the time of groin access to at least TICI 2b revascularisation.</span></p> <p><br /><span style="font-size: 10pt;">The overall successful recanalisation rate (TICI 2b&ndash;3) was 95%. The average time to recanalisation was 36.6 minutes (SD=26.4 minutes). The aspiration component of the ADAPT technique successfully recanalised occluded vessels 78% of the time and when it was used as a standalone technique the average time to recanalisation was 31.6 minutes (SD=23.3 minutes). The authors add that, in cases where an adjunctive device, such as a stent retriever was used, the time to revascularisation was longer (p&lt;0.0001; average time 56.8 minutes; SD=29.1 minutes).</span></p> <p><br /><span style="font-size: 10pt;">Overall the 5MAX catheter was used in 44 cases, the 5MAX ACE was used in 44 cases, the 3MAX (Penumbra) in six cases, in four cases the Navien 058 (EV3, Covidien) and in one case the Neuron 088 MAX (Penumbra). TICI 2b or 3 revascularisation with aspiration alone was achieved in 75% of cases where the 5MAX was used vs. 82% (p=0.44) when a 5MAX ACE was used.</span></p> <p><br /><span style="font-size: 10pt;">The National Institutes of Health Stroke Scale (NIHSS) at presentation was 17.3 (median 17; SD=6.4) and was improved to 7.3 (median 4; SD=7.5).</span></p> <p><br /><span style="font-size: 10pt;">The authors report that there were no incidences of postprocedure spontaneous intracranial haemorrhage. They add that, compared with the outcomes of the stent retriever data reported, ADAPT has similar rates of good functional outcome (mRS 0&ndash;2), mortality and device-related complications.</span></p> <p><br /><span style="font-size: 10pt;">Modified Rankin Scale score (mRS) was reported in 81 patients with 40% achieving a mRS score of 0&ndash;2, and in 20% of cases an score of 6 at three-month follow-up was achieved.</span></p> <p><br /><span style="font-size: 10pt;">In 78% of cases, according to Turk <em>et al</em>, where ADAPT alone was successful, 47% of patients achieved a mRS score on 0&ndash;2 and 14% has a score of 6. Where a stent retriever was used with ADAPT (or was unsuccessful), 18% achieved mRS 0&ndash;2 and 35% achieved a score of 6.</span></p> <p><br /><span style="font-size: 10pt;">Concluding, the authors say that catheter aspiration thrombectomy is an effective, novel technique to achieve revascularisation as a first-line therapy. It has previously only been reported as a bailout after failure of traditional revascularisation techniques.</span></p> <p><br /><span style="font-size: 10pt;">They say that ADAPT is made possible because of the availability of newer, flexible, atraumatic, large bore aspiration catheters and add that their &ldquo;multicentre series supports the hypothesis that, in comparison with modern thrombectomy devices, ADAPT is a fast, simple, efficient and safe strategy to achieve revascularisation in patients with acute ischaemic stroke secondary to large vessel occlusion.&rdquo;</span></p></div> Morphology and interval growth are predictive factors of intracranial aneurysm rupture http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/morphology-and-interval-growth-are-predictive-factors-of-intracranial-aneurysm-rupture 2014-03-21T11:01:00Z 2014-03-21T11:01:00Z <div id="ImageMain14" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/morphology-and-interval-growth-are-predictive-factors-of-intracranial-aneurysm-rupture"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Will_Mehan_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction14" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>In a study conducted by William Mehan <em>et al,</em> it was found that for patients with unruptured intracranial aneurysms, multilobulated morphology and interval growth of the unruptured aneurysms are &ldquo;characteristics predictive of a higher risk of subsequent rupture during conservative CT angiography (CTA) follow-up.&rdquo;</strong></span></p> </div><div id="Text114" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Mehan and colleagues (Massachusetts General Hospital, Harvard Medical School, Boston, USA) say that, although there have been other multicentre prospective studies (ISUIA, UCAS and SUAVE) demonstrating characteristics associated with rupture, the &ldquo;natural history of unruptured intracranial aneurysms remain uncertain.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Therefore, the Massachusetts group aimed to identify factors predictive of rupture, or confirm the characteristics found in the aforementioned studies. They say that this is important as aneurysm rupture is associated with &ldquo;significant morbidity and mortality&rdquo;.</span></p> <p><br /><span style="font-size: 10pt;">The single centre study, published in the <a href="http://jnis.bmj.com/" target="_blank"><em>Journal of NeuroInterventional Surgery </em></a>was a retrospective review of patients with unruptured intracranial aneurysms followed with serial CT angiography studies between January 1999 and December 2010. The following features for each aneurysm were catalogued from the official radiologic reports and CTA images: maximum diameter, growth between follow-up studies, location, multiplicity, wall calcification, intraluminal thrombus and morphology. Univariate logistic regression analysis of the potential independent risk factors for aneurysm rupture was performed. Statistically significant risk factors from the univariate analysis were then entered into a multivariate logistic regression analysis. &nbsp;</span></p> <p><br /><span style="font-size: 10pt;">During the study period, a total of 3,033 cerebral aneurysms were referred to the institution, of which 614 ruptured. A total of six aneurysms in six different patients ruptured during the CT angiography follow-up period, yielding an overall rupture rate of 3.3% and an annual rupture rate of 0.97%. The investigators initially performed a univariate logistic regression analysis of potential risk factors for aneurysm rupture. All six ruptured aneurysms were at least 9mm in maximum diameter compared with a mean of 5.4mm for the unruptured aneurysms (p=0.003).</span></p> <p><span style="font-size: 10pt;">&nbsp;</span><br /><span style="font-size: 10pt;">Four of six ruptured aneurysms demonstrated interval growth by the time of rupture compared with four of 174 unruptured aneurysms (p&lt;0.0001). In one of the four ruptured aneurysms that enlarged between serial CT angiography follow-up studies, interval growth was demonstrated on CT angiography studies obtained prior to the study performed at the time of rupture. The mean growth for the aneurysms that ruptured was 4.25mm. Four of six ruptured aneurysms demonstrated multilobulated morphology compared with 16 of 174 of unruptured aneurysms. In three of the four multilobulated aneurysms that ruptured, multilobulated morphology was demonstrated on CT angiography studies obtained prior to the study performed at the time of rupture. A single ruptured aneurysm demonstrated neither interval growth nor multilobulated morphology on CT angiography. &nbsp;</span></p> <p><br /><span style="font-size: 10pt;">According to Mehan <em>et al</em>, the non-invasive nature of CT angiography coupled with its relatively high spatial resolution, speed and availability make CT angiography an excellent modality for the serial follow-up of known unruptured intracranial aneurysms. Based on the study findings, unruptured intracranial aneurysms with a multilobulated morphology and/or interval growth between follow-up CT angiography studies are at increased risk of rupture. Further studies of conservative CT angiography follow-up of unruptured intracranial aneurysms with longer follow-up periods and larger numbers of ruptured aneurysms are necessary.</span></p> <p><br /><span style="font-size: 10pt;">The authors conclude that this study demonstrates that multilobulated morphology and interval growth of unruptured intracranial aneurysms are characteristics predictive of a higher risk of subsequent rupture during conservative CT angiography follow-up. The presence of these features could help guide clinical decisions as to whether these aneurysms are followed conservatively or treated.</span></p></div> FDA approval for Neuraceq (florbetaben F18 injection) http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/fda-approval-for-neuraceq-florbetaben-f18-injection 2014-03-21T10:08:00Z 2014-03-21T10:08:00Z <div id="ImageMain15" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/fda-approval-for-neuraceq-florbetaben-f18-injection"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Neura_Ceq_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction15" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The US Food and Drug Administration (FDA) has approved Piramal Imaging&rsquo;s Neuraceq (florbetaben F18 injection).

Of these, 71 studies, involving 2634 patients, were considered of the highest quality and were included in the review. Nineteen studies followed traumatic brain injury patients over time and five looked at the effects of treatment interventions.&nbsp;</span><br /> <br /><span style="font-size: 10pt;">The findings of the systematic review include: 1) SPECT is more sensitive compared to standard anatomical CT and MRI in detecting brain abnormalities in traumatic brain injury; 2) SPECT correlates with psychological and neurological outcomes; 3) SPECT can be used to evaluate treatment interventions. SPECT scans showed abnormalities not seen on MRI and CT in all 10 of the studies that investigated this question (100%).&nbsp;</span><br /> <br /><span style="font-size: 10pt;">It was found that a normal SPECT study right after an injury is highly predictive of a good clinical outcome for patients, but an abnormal scan right after an injury was not highly predictive of the ultimate outcome (59%), as the brain has many healing mechanisms. But if the second scan three months later was also abnormal, the scan was highly predictive of poor outcome.&nbsp;</span><br /> <br /><span style="font-size: 10pt;">&ldquo;The bottom line is if a brain SPECT is normal after traumatic brain injury, patients do well but we need to see at least two abnormal scans over time to see if they do poorly,&rdquo; says psychiatrist and SPECT expert Daniel Amen, one of the co-authors of the paper. &ldquo;These important findings can have important implications for diagnosis and brain rehabilitation in persons with traumatic brain injury.&rdquo;&nbsp;</span><br /> <br /><span style="font-size: 10pt;">According to Theodore Henderson, a senior author on the study, &ldquo;Persons with mild traumatic brain injury, which is often referred to as concussion or post-concussion syndrome, may not be properly identified as having credible neurological problems because commonly used anatomical CT or MRI scans in mild brain trauma are abnormal less than 10% of the time. These same patients may have recurring psychiatric symptoms such as depression, attention problems, and impulse control issues. Commonly, they are referred to psychiatrists who generally do not use neuroimaging to diagnose and treat brain disorders.

This analysis reveals that the maximal periods of benefit correlate with the two surgical interventions. Importantly, as the &lsquo;bell-shaped curve&rsquo; associated with each intervention is likely due to disease progression, increasing the total cell dose, and applying multiple applications of these stem cells, may increase both the length and magnitude of the potential benefit.

Of 18 patients who treated at least three attacks, six were pain free on two out of three occasions (33%).</span><br /> <br /><span style="font-size: 10pt;"> ElectroCore&rsquo;s proprietary, non-invasive electrical stimulation therapy works by activating specific fibres in the vagus nerve bundle. This activation causes the release of inhibitory neurotransmitters within the central nervous system, and reduces the over expression of the excitatory neurotransmitter glutamate, which has been implicated in a number of different disorders.</span></p> <p><br /><span style="font-size: 10pt;">Patients self-treat by holding the device on their neck over the vagus nerve for two minutes.

While mild concussions generally cause no loss of consciousness, they can induce other symptoms such as dizziness, nausea, trouble concentrating, memory problems and headaches. Severe concussions can cause a loss of consciousness. Most concussions resolve in days or weeks, but some patients can suffer symptoms more than a year after injury.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The authors examined whether sports-related concussions were associated with elevated levels of blood biochemical markers of injury to the central nervous system. Swedish Hockey League players (n=288) underwent preseason baseline examination for concussion and some underwent preseason blood testing. Of the 288 players, 35 had a sports-related concussion from September 2012 through January 2013, and 28 of those players were included in the study. Players underwent repeated blood testing in the hours and days after their injuries and when they returned to play.</span></p> <p><br /><span style="font-size: 10pt;"> The authors report that players who had concussions had increased levels of the injury biomarker T-tau compared with preseason levels. The highest levels of T-tau were measured in players during the first hour after a concussion and declined during the first 12-hour period but remained elevated six days later compared with preseason blood results. T-tau levels after concussion also were associated with the number of days it took for concussion symptoms to resolve and for players to safely return to competition.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The authors conclude: &ldquo;Plasma T-tau, which is a highly central nervous system-specific protein, is a promising biomarker to be used both in the diagnosis of concussion and in decision making as to when an athlete can be declared fit for return to play.&rdquo;</span></p></div> Stroke survivors may lose month of healthy life for 15-minute delay in treatment http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/stroke-survivors-may-lose-month-of-healthy-life-for-15-minute-delay-in-treatment 2014-03-17T09:40:00Z 2014-03-17T09:40:00Z <div id="ImageMain30" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/stroke-survivors-may-lose-month-of-healthy-life-for-15-minute-delay-in-treatment"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Atte_Meretoja_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction30" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Every 15-minute delay in delivering a clot-busting drug after stroke robs survivors of about a month of disability-free life, according to a new study in the American Heart Association journal&nbsp;<span style="color: #800000;"><a href="https://stroke.ahajournals.org/content/early/2014/03/13/STROKEAHA.113.002910.abstract" target="_blank"><span style="color: #800000;"><em>Stroke</em></span></a></span>.</strong></span></p> </div><div id="Text130" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">On the other hand, speeding treatment by just one minute means another 1.8 days of healthy life, researchers said.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;&lsquo;Save a minute; save a day&rsquo; is the message from our study, which examined how even small reductions in treatment delays might benefit patients measurably in the long run,&rdquo; says Atte Meretoja, lead author of the study and associate professor of neurology at the University of Melbourne in Australia.</span></p> <p><br /><span style="font-size: 10pt;">The clot-busting drug&nbsp;tissue plasminogen activator&nbsp;(tPA) to treat ischemic&nbsp;stroke, should be given within 4.5 hours of symptom onset.

According to a release, the discoveries could have implications in the diagnosis, monitoring and treatment of Alzheimer&rsquo;s disease, chronic traumatic encephalopathy and traumatic brain injury.&nbsp;</strong></span></p> </div><div id="Text138" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">According to a company release, the research studies provide evidence that exosomes can serve as a &ldquo;liquid biopsy&rdquo; to diagnose neurologic conditions. While exosomes from the central nervous system have previously been identified in the cerebrospinal fluid, the Aethlon-Exosome Sciences study identified exosomes carrying brain-specific markers tau, beta-amyloid, glycoprotein A2B5 and S100B protein in the peripheral circulation of affected individuals. The discoveries provide a basis for an exosome-based platform that could enable the simultaneous identification of multiple brain specific markers that are transported across the blood-brain barrier and into the circulatory system.</span><br /><br /><span style="font-size: 10pt;">&ldquo;This advancement represents a new paradigm for brain injuries. In addition to providing definitive diagnosis, the proteomic and transcriptomic characterisation of exosomes isolated specifically from the brain will provide a window into the molecular mechanisms underlying acute and chronic brain injuries,&rdquo; says Exosome Sciences chief scientific officer, Douglas Taylor.</span><br /><br /><span style="font-size: 10pt;">As a result of the discoveries, brain-derived exosomes can be specifically isolated and the protein and RNA cargoes identified. In studies of brain tissue, specific RNAs have been associated with development of neurological disorders, contributing to the onset and progression of brain injuries. Exosomal RNA and protein cargoes represent surrogates to brain biopsies and have utility as stable, clinically accessible biomarkers for brain injury detection, stratification of patients and therapeutic outcomes.</span><br /><br /><span style="font-size: 10pt;">&ldquo;With the exosome-based technologies developed by our group, we are at the verge of breakthroughs for the management and treatment of brain injuries and diseases that have been associated with disability and death,&rdquo; says Cicek Gercel-Taylor, clinical research director at Exosome Sciences.</span><br /><br /><span style="font-size: 10pt;">Circulating biomarkers have been proposed for the definitive diagnosis and monitoring treatment of brain injuries. The approach would enable diagnosing the condition, identifying processes that are difficult to image, monitoring responses to interventions, and predicting those who are at risk for long-term neurologic consequences. However, circulating biomarkers, such as free protein and nucleic acids, are extremely unstable in circulation. Therefore, a high steady-state must be reached for detection, which is generally not observed except in severe cases. To circumvent these issues, exosome-associated biomarkers can be utilised as they are stable and detectable in the circulation.</span></p></div> New published paper shows efficacy of Lpathomab in traumatic brain injury models http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-published-paper-shows-efficacy-of-lpathomab-in-traumatic-brain-injury-models 2014-03-05T16:01:00Z 2014-03-05T16:01:00Z <div id="ImageMain39" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-published-paper-shows-efficacy-of-lpathomab-in-traumatic-brain-injury-models"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/005/New-brain_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction39" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Lpath, according to a company release, has brought scientists one step closer to finding a potential treatment for traumatic brain injury with a recent publication showing that Lpathomab, an anti-lysophosphatidic acid antibody, reverses much of the damage caused by trauma to the nervous system.</strong></span></p> </div><div id="Text139" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">As published by the <a href="http://www.jneuroinflammation.com/" target="_blank"><strong>Journal of Neuroinflammation</strong></a> (vol 11, article 37), Lpathomab can be used to reduce the size of a traumatic brain injury and to improve functional behavioural outcomes in experimental animal models. The antibody works as a molecular sponge by soaking up lysophosphatidic acid, a molecule that can damage neurons and promote dangerous inflammatory responses in the central nervous system.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><br /><span style="font-size: 10pt;">In collaboration with scientists at the University of Melbourne, the antibody was tested in mice that had traumatic brain injuries. A key finding of the study was the significant efficacy of administering Lpathomab after an injury, thus demonstrating a potential therapeutic benefit. Also shown for the first time in this paper was that human patients with traumatic brain injury exhibited substantial increases in the levels of lysophosphatidic acid in the cerebrospinal fluid after injury, a finding also seen in the injured mouse model of traumatic brain injury; such data suggest that lysophosphatidic acid is a valid target for therapeutic intervention.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><br /><span style="font-size: 10pt;">Lpath and its Melbourne collaborators have recently shown that Lpathomab provides protection against neuronal cell death and scarring in experimental models of spinal cord injury, published recently in the <a href="http://ajp.amjpathol.org/" target="_blank"><strong>American Journal of Pathology</strong></a> (Goldschmit <em>et al</em>, vol 181,&nbsp;978-992).

The study included 8,373 adolescents from 13 to 17 years of age with recurring headaches.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Paediatric and adolescent use of opioids is a concern,&rdquo; says Eric Wall, past chair of the American Academy of Family Physicians&rsquo; Commission on Science. &ldquo;The risk of abuse, as well as the potential for redirection, such as sharing with others, is high among adolescents.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Forty-six percent of those complaining of headache received an opioid prescription. Of those who received a prescription, nearly half &ndash; or 48% &ndash; received only one prescription, while 23% received two prescriptions and 29% received three or more prescriptions.</span></p> <p><br /><span style="font-size: 10pt;">Opioids, while effective in relieving pain, are not effective for treating migraine and the American Academy of Neurology states opioids should be used only as rescue therapy for acute migraine in specific situations. Medical guidelines recommend nonsteroidal anti-inflammatory drugs or triptans as first-line therapy. Also, other studies have suggested that opioid use may contribute to the development of chronic daily headache in patients with episodic migraine and may actually prevent reversal of the migraine process.</span></p> <p><br /><span style="font-size: 10pt;">Teenagers with visits for headache to the emergency department had twice the rate of opioid prescriptions as those who had not visited the emergency department. And, those who had three or more emergency department visits were four times more likely to have opioid prescriptions.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;However, the study contrasted with previous studies primarily focused on adult populations, which have suggested that patients seeking emergency treatment for headache may be seeking narcotics,&rdquo; says lead author Andrea DeVries, HealthCore director of payer and provider research. &ldquo;On teenagers&rsquo; first visits to the emergency department, most of them had no recent history of opioid prescription.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Opioids &ndash; such as morphine, codeine, and oxycodone &ndash; are commonly prescribed to alleviate pain, however there have been increasing concerns regarding physical dependence and addiction. Other studies have found that prescription opioid abuse is the fastest growing form of drug abuse, however there is controversy regarding the level of risk for dependence in the general population.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;One goal in doing this research, and based on the American Academy of Paediatrics&rsquo; input was to examine how the actual practice patterns for treating paediatric headache were following American Academy of Neurology guidelines,&rdquo; says Alan Rosenberg, WellPoint vice president for medical policy. &ldquo;The general impression was that opioid prescriptions for this population would be low. When the results were obtained, we all felt it important to share this information with physicians and build awareness of the issue.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">The study showed much higher rates of opioid prescription than rates of around 12% that had been reported previously.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;We used both medical and pharmacy claims in our data gathering, which allowed for a more comprehensive capture of prescription drug use than medical record or facility-based studies,&rdquo; said DeVries. &ldquo;Based on this work, we believe previous studies may have underreported prescription rates.&rdquo;</span></p></div> Public to get a glimpse into cutting edge brain research http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/public-to-get-a-glimpse-into-cutting-edge-brain-research 2014-03-04T15:01:00Z 2014-03-04T15:01:00Z <div id="ImageMain45" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/public-to-get-a-glimpse-into-cutting-edge-brain-research"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Brain_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction45" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>University of Leicester scientists are making huge strides in increasing our knowledge of the brain as well as neurological disorders which affect millions of people worldwide.

Patients received treatment during three visits per week, for six weeks, as the standard of care in the US. They then returned for follow-up visits at one week, one month, and six months. The study found that Nexstim&rsquo;s non-invasive Navigated Brain Stimulation system used as an adjunct to therapy promoted lasting improvements in patients&rsquo; motor function compared to the sham group. </span><br /> <br /><span style="font-size: 10pt;"> Nexstim&rsquo;s Navigated Brain Stimulation system uses stereotactic, MRI-guided transcranial magnetic stimulation to non-invasively modulate precise areas of the motor cortex. The system&rsquo;s e-field-based targeting tool allows the therapist to accurately locate the patient&rsquo;s exact stimulation location using technology similar to navigating the globe with a global positioning system (GPS). The navigated transcranial magnetic stimulation was used to stimulate the patient&rsquo;s non-injured hemisphere at low frequency.

The MicroNet technology is a single fibre knitted mesh wrapped on an open cell stent design in order to trap the debris that can travel downstream after a patient is treated with traditional stenting methods. This protects patients from plaque debris and blood clots breaking off and traveling distally in the arteries which can lead to life threatening strokes. The size, or aperture, of the MicroNet &lsquo;pore&rsquo; is only 150-180 microns in order to maximize protection against plaque and thrombus.</span></p> <p><br /><span style="font-size: 10pt;">The CGuard is CE marked and is currently being evaluated clinically in Europe.

This funding mechanism is designed to support creative, cutting edge research in well-established research laboratories, under the direction of established investigators.</span></p> <p><br /><span style="font-size: 10pt;">Descriptions of the work funded by the 2014 Scientific Innovations Awards follow:</span></p> <p><br /><span style="font-size: 10pt;">A &ldquo;burst&rdquo; is a brief period of high-frequency activity within neurons that can have a powerful impact on brain circuits. Symptoms in human diseases like Parkinson&rsquo;s and&nbsp;epilepsy&nbsp;are thought to be influenced by &ldquo;overly-exuberant&rdquo; bursting. With his 2014 Scientific Innovations Award,&nbsp;Christopher I Moore, Department of Neuroscience at&nbsp;Brown University, will conduct research to determine if biological strategies can be effective at modulating thalamic bursts. Data gathered may indicate potential for entire new treatment strategies, reducing or eliminating the need </span><span style="font-size: 10pt;">for intrusive and painful electrode implants.</span></p> <p><br /><span style="font-size: 10pt;">Hurler syndrome&nbsp;is a genetic disease that manifests itself after birth through developmental delay, dwarfism, mental retardation and frequently, death prior to ten years of age. With a 2014 Scientific Innovations Award,&nbsp;W Mark Saltzman, Department of Biomedical Engineering at&nbsp;Yale University, will attempt to correct the gene disorder in Hurler syndrome in mice by &ldquo;editing&rdquo; genes in utero using nanotechnology. The potentially transformative approach, if successful, can be applied to any single gene defect &ndash; such as Huntington&rsquo;s disease and Fragile-X syndrome.</span></p> <p><br /><span style="font-size: 10pt;">Disruptions in neural circuitry cause many diseases such&nbsp;autism&nbsp;and schizophrenia. However, scientists&rsquo; ability to study brain wiring has been greatly limited. Using a 2014 Scientific Innovations Award,&nbsp;Anthony Zador, Department of Neuroscience, Cold Spring Harbor Laboratory, will test an innovative alternative to mapping neural connectivity. Rather than &ldquo;take&rdquo; a picture of brain wiring and connectivity through microscopy, Zador will &ldquo;build&rdquo; a picture or model through a unique DNA sequencing technique. The approach will be used to assess the brain wiring in a mouse model of autism. If successful, this technique can potentially be used to analyse neural circuitry disruptions in a great number of neuropsychiatric disorders.</span></p> <p><br /><span style="font-size: 10pt;">The Scientific Innovations Award grants are specifically for projects that may be too innovative and speculative for traditional funding sources but still have a high likelihood of producing important findings in a very short timeframe. It is expected that investigations supported by these grants will yield high impact data and result in additional major grant funding and significant publications in key journals, the press release reports.</span></p></div> MRI increases the incidence of extra-axial intracranial tumour diagnosis http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/mri-increases-the-incidence-of-extra-axial-intracranial-tumour-diagnosis 2014-02-10T12:15:00Z 2014-02-10T12:15:00Z <div id="ImageMain68" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/mri-increases-the-incidence-of-extra-axial-intracranial-tumour-diagnosis"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/035/Ole-Solheim-web_updated.jpg" border="0" vspace="5" /></a></div><div id="Introduction68" style="clear:both;"> <p><strong><span style="font-size: 11pt;">A Norwegian study has found that cerebral, regional magnetic resonance imaging (MRI) can lead to an increase in incidence rates of intracranial tumour diagnosis.</span></strong></p> </div><div id="Text168" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The authors Ole Solheim, department of Neurosurgery, St Olav&rsquo;s University Hospital, Trondheim, Norway and others say that a subgroup analysis revealed that there was correlation between increased diagnosis of benign extra-axial tumours but not intra-axial tumours. The results were published in <strong><a href="http://thejns.org/" target="_blank"><em>Journal of Neurosurgery</em></a></strong>.</span><br /><br /><span style="font-size: 10pt;">&ldquo;It is assumed that the observed increase in brain tumour incidence may at least partially be explained by increased use of MRI,&rdquo; Solheim <em>et al</em> say. They therefore aimed to examine the regional frequencies of cerebral MRI use correlate to regional incidence rates of intracranial tumours and survival of the patients with these tumours.</span><br /><br /><span style="font-size: 10pt;">From data correlated from Norwegian population registries (January 2002 to December 2007), the authors investigated annual regional rates of cerebral MRI scans regional age- and sex-adjusted brain tumours.</span><br /><br /><span style="font-size: 10pt;">The annual number of cerebral MRI scans increased substantially, according to the results, during the study period, with large regional differences.

The association between MRI scans per capita and overall survival was associated with the number of cerebral MRI scans per capita in the county of residence at the time of diagnosis (log-rank test p=0.029). However, after adjusting for year of diagnosis and geographical health region of the Norwegian neurological centres, this was found not to be statistically significant (p=0.076).</span><br /><br /><span style="font-size: 10pt;">Concluding, Solheim and colleagues say: &ldquo;Largely due to the incidental discovery of benign extra-axial tumours, regional differences in the use of cerebral MRI in outpatients affect observed incidence rates of intracranial tumours.&rdquo;</span></p></div> BrainStorm signs definitive agreement with Mayo Clinic for ALS clinical trial http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/brainstorm-signs-definitive-agreement-with-mayo-clinic-for-als-clinical-trial 2014-02-05T15:01:00Z 2014-02-05T15:01:00Z <div id="ImageMain69" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/brainstorm-signs-definitive-agreement-with-mayo-clinic-for-als-clinical-trial"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Windebank_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction69" style="clear:both;"> <p><strong><span style="font-size: 11pt;">BrainStorm Cell Therapeutics has announced that it has signed a definitive agreement with the Mayo Clinic in Minnesota, USA to conduct its phase II clinical trial of NurOwn in amyotrophic lateral sclerosis (ALS), pending FDA approval.

In this study, researchers will develop a better understanding of those cognitive changes and their relationship to physical functioning during the disease course. The aim is to both better understand this interaction and to develop a new disease staging system incorporating both cognitive and physical changes that can be used in clinical trials to track response to therapy.</span></p> <p><br /><span style="font-size: 10pt;">AAV therapeutic agents for ALS</span><br /><span style="font-size: 10pt;"> Principal Investigator: Zuoshang Xu, M.D. Ph.D.,&nbsp;University of Massachusetts, USA.</span></p> <p><br /><span style="font-size: 10pt;">In this study, researchers will further develop a gene therapy delivery vehicle, or vector, using a new type of adeno-associated virus (AAV). AAV has been shown to be a versatile vector for reaching neurons in the central nervous system with a good safety record. Here, the scientists will develop the ability to pack a so-called &ldquo;interfering RNA&rdquo; into the vector and test its therapeutic ability in rats carrying a disease-causing SOD1 mutation. Success in this study will increase the rationale for development of gene therapy in people with ALS.</span></p> <p><br /><span style="font-size: 10pt;">Familial ALS exome capture and genomic sequencing collaboration</span><br /><span style="font-size: 10pt;"> Principal Investigators:&nbsp;Benjamin Neale, Ph.D. (Massachusetts&nbsp;General Hospital,&nbsp;Boston, USA) and&nbsp;Christopher Shaw, M.D. (Kings College&nbsp;London, UK)</span></p> <p><br /><span style="font-size: 10pt;">Several large-scale studies have produced volumes of data on gene variants associated with an increased risk for ALS. In this project, researchers will combine the data from those studies to better determine which of these gene variants is most strongly associated with disease. A key aspect of the research will be to stringently remove from consideration those variants that, despite some hint of association, are unlikely to be actually involved in ALS, thus streamlining the search for true risk genes. This project represents a major collaboration among multiple research groups, and its results will likely set the stage for developing much deeper insights into the genetics of ALS.</span></p></div> Stenting without post-dilation is a safe and feasible strategy in the carotid artery http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/stenting-without-post-dilation-is-a-safe-and-feasible-strategy-in-the-carotid-artery 2014-01-30T10:20:00Z 2014-01-30T10:20:00Z <div id="Introduction73" style="clear:both;"> <p><strong><span style="font-size: 11pt;">The results of a study published in the <a href="http://jnis.bmj.com/" target="_blank"><em>Journal of NeuroInterventional Surgery</em></a> have shown that carotid stenting without post-dilation is safe and effective.</span></strong></p> </div><div id="Text173" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Atshushi Ogata (department of Neurosurgery, Saga University, Japan) and others say that traditional carotid artery stenting involves post-dilation at the end phase of the intervention as there is a risk of embolic stroke caused by atheromatous plaque dislodgement. The authors explain that &ldquo;most emboli are produced during the post-dilation phase, which can occur if the balloon pushes the stent struts against the atheromatous plaque. Post-dilation is therefore considered to be the riskiest part of the procedure.&rdquo;<br /><br /></span><span style="font-size: 10pt;">Ogata and colleagues aimed, in their study, to demonstrate the safety and efficacy of carotid artery stenting without post-dilation.<br /><br /></span><span style="font-size: 10pt;">One hundred and sixty nine patients with 179 carotid artery stenoses between them, which were stented without post-dilation, were included in the study. A total of 108 lesions (61.4%) were symptomatic and 68 (38.6%) were asymptomatic. Two patients were excluded because the stenting had to be performed with post-dilation. The patient data was taken from a retrospective registry that ran between May 2005 and April 2012.<br /><br /></span><span style="font-size: 10pt;">&ldquo;Carotid artery stenting was performed successfully for all lesions, although major adverse events [stroke, myocardial infarction or death within 30 days] occurred in four patients (2.3%),&rdquo; note Ogata </span><em style="font-size: 10pt;">et al</em><span style="font-size: 10pt;">.<br /><br /></span><span style="font-size: 10pt;">The authors went on to say that the results show that the overall stroke rate was 2.3% within 30 days after carotid artery stenting, there were no myocardial infarctions and no patients died. Cerebral infarction occurred in two patients (1.1%) and transient ischaemic attack in three (1.7%).<br /><br /></span><span style="font-size: 10pt;">&ldquo;Our carotid artery procedure is effective, particularly in symptomatic patients. Although it might be possible to employ new types of stents and embolic protection devices in the future, concepts to minimise plaque disruption are important because plaque deposits remain contained in the vessel wall in carotid stenting procedures.&rdquo;<br /><br /></span><span style="font-size: 10pt;">They add that in 174 lesions (98.9%) closed-cell stents were used and in two lesions open-cell stents were used, therefore no advantage of open- over closed-cell stents could be observed.</span></p></div> Brain surgeon teams with NASA scientists to develop 3D high-definition surgical instruments http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/brain-surgeon-teams-with-nasa-scientists-to-develop-3d-high-definition-surgical-instruments 2014-01-29T11:06:00Z 2014-01-29T11:06:00Z <div id="ImageMain74" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/brain-surgeon-teams-with-nasa-scientists-to-develop-3d-high-definition-surgical-instruments"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/035/shahinian-web_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction74" style="clear:both;"> <p><strong><span style="font-size: 11pt;">Brain surgeon Hrayr Shahinian (the Skull Base Institute, Los Angeles, USA), a pioneer in minimally invasive surgery, and NASA&rsquo;s Jet Propulsion Laboratory in Pasadena, USA, have introduced the next generation of high-tech surgical instruments to remove tumours and treat other brain abnormalities.</span></strong></p> </div><div id="Text174" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">MARVEL (Multi angle rear viewing endoscopic tool) captures and displays 3D high-definition images of the brain and enables surgeons to perceive depth and &ldquo;peek around corners&rdquo; that, until now, have been off limits, it says in a company release.

According to the press release, this is the first study to use neuroimaging to investigate these two, separable aspects of fatigue.<br /><br /></span><span style="font-size: 10pt;">&ldquo;We looked specifically at the relationship between individuals&rsquo; self-reported fatigue and objective measures of cognitive fatigue using state-of-the-art neuroimaging,&rdquo; explains Genova. &ldquo;The importance of this work lies in the fact that it demonstrates that the subjective feeling of fatigue can be related to brain activation in specific brain regions. This provides us with an objective measure of fatigue, which will have incalculable value as we begin to test interventions designed to alleviate fatigue.&rdquo;<br /><br /></span><span style="font-size: 10pt;">In experiment one, patients were scanned during performance of a task designed to induce cognitive fatigue.&nbsp;Investigators looked at the brain activation associated with state fatigue.&nbsp;In experiment two, DTI was used to examine where in the brain white matter damage correlated with increased trait fatigue in individuals with multiple sclerosis, as assessed by the fatigue severity scale. The findings of both the experiments support the role of a striato-thalamic-frontal cortical system in fatigue, suggesting a &ldquo;fatigue-network&rdquo; in multiple sclerosis.<br /><br /></span><span style="font-size: 10pt;">&ldquo;Identifying a network of fatigue-related brain regions could reframe the current construct of cognitive fatigue and help define the pathophysiology of this multifaceted yet elusive symptom of multiple sclerosis,&rdquo; says&nbsp;John DeLuca, vice president of research and training at Kessler Foundation. &ldquo;Replication of these findings with larger sample sizes will be an important next step.&rdquo;</span></p></div> Take head injuries seriously, says NICE http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/take-head-injuries-seriously-says-nice 2014-01-24T11:43:00Z 2014-01-24T11:43:00Z <div id="ImageMain82" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/take-head-injuries-seriously-says-nice"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/035/Mark-Baker-web_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction82" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Time is of the essence when treating head injuries to avoid potentially serious complications, including disability or death, says the&nbsp;<a href="http://www.nice.org.uk/" target="_blank">National Institute for Health and Care Excellence</a>&nbsp;(NICE).

APOE has different alleles, says the study&rsquo;s senior author, Jeffrey R Petrella, associate professor of radiology at Duke University School of Medicine in Durham, USA. &ldquo;We all carry two APOE alleles, and most people have at least one copy of the APOE epsilon 3 (ɛ3) variant, which is considered neutral with respect to Alzheimer&rsquo;s risk&rdquo;.<br /><br /></span><span style="font-size: 10pt;">The less common epsilon 4 (ɛ4) allele, in contrast, is associated with a higher risk for development of Alzheimer&rsquo;s disease, earlier age of onset, and faster progression in those effected, as compared with the other APOE alleles.<br /><br /></span><span style="font-size: 10pt;">Petrella and colleagues recently analysed data from the Alzheimer&rsquo;s Disease Neuroimaging Initiative (ADNI) involving 237 patients, mean age 79.9, with mild cognitive impairment. The researchers used magnetic resonance imaging (MRI) to measure brain atrophy rates in these patients over a 12- to 48-month period.</span></p> <p><span style="font-size: 10pt;"><br /></span><span style="font-size: 10pt;">The ɛ4 carriers in the study group exhibited markedly greater atrophy rates than ɛ3 carriers in 13 of 15 brain regions hypothesised to be key components of the cognitive networks disrupted in Alzheimer&rsquo;s.<br /><br /></span><span style="font-size: 10pt;">&ldquo;The results showed atrophy in brain regions we know are affected by Alzheimer&rsquo;s disease, in a population of patients who do not have Alzheimer&rsquo;s disease, but are at risk for it,&rdquo; Petrella notes. &ldquo;This suggests the possibility of a genotype-specific network of related brain regions that undergo faster atrophy in mild cognitive impairment and potentially underlies the observed cognitive decline.&rdquo;<br /><br /></span><span style="font-size: 10pt;">The researchers did not explore why APOE ɛ4 might accelerate atrophy, but the effect is likely due to a combination of factors, adds Petrella.<br /><br /></span><span style="font-size: 10pt;">&ldquo;The protein has a broad role in the transport and normal metabolism of lipids and a protective function on behalf of brain cells, including its role in the breakdown of beta-amyloid, one of the proteins implicated in the pathophysiology of Alzheimer&rsquo;s disease,&rdquo; he says.<br /><br /></span><span style="font-size: 10pt;">With MRI playing an increasingly prominent role in mild cognitive impairment research, Petrella predicts that increased knowledge about the effects of APOE will improve the design and execution of future clinical trials. For instance, researchers could enrich their samples with &epsilon;4 patients in mild cognitive impairment prevention trials to better determine potential treatment effects on brain regions vulnerable to degeneration.<br /><br /></span><span style="font-size: 10pt;">The advances in knowledge are expected to help expand the role of MRI measures in clinical trials investigating novel drugs with potentially disease-modifying capabilities.<br /><br /></span><span style="font-size: 10pt;">&ldquo;Current US Food and Drug Administration-approved drugs treat symptoms, but do not modify the underlying cause of the disease,&rdquo; Petrella states. &ldquo;We want to make continued inroads toward the goal of developing and testing drugs that modify the disease process itself.&rdquo;</span></p></div> 13,000 patients treated with Visius surgical theatre since 2005, study indicates http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/13000-patients-treated-with-visius-surgical-theatre-since-2005-study-indicates 2014-01-16T11:18:00Z 2014-01-16T11:18:00Z <div id="ImageMain87" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/13000-patients-treated-with-visius-surgical-theatre-since-2005-study-indicates"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/028/VISIUS-surgical-suite_web_Main.jpg" border="0" vspace="5" /></a></div><div id="Text187" style="clear:both; text-align:left"><p><span style="font-size: 10pt;"><strong><span style="font-size: 11pt;">Results of an internal study of 40 worldwide Visius surgical theatre hospital customers indicates that nearly 13,000 patients have been treated using intraoperative MRI (iMRI) since the first installation in 2005</span></strong><br /><br /></span><span style="font-size: 10pt;">Four of 27 US hospitals, located in Boston, St. Louis and Minneapolis and St Paul, currently using Visius iMRI are approaching 1,000 cases performed.<br /><br /></span><span style="font-size: 10pt;">Frederick Boop, co-director of the Le Bonheur Neuroscience Institute in Memphis, USA, credits VISIUS iMRI with reducing reoperation rates. &ldquo;Intraoperative MRI is an important tool in our paediatric programme by&nbsp; allowing us to get a more complete removal of these tumours and better&nbsp; overall visualisation without moving the patient and knowing we will not&nbsp; have to bring the patient back for another operation,&rdquo; he says.<br /><br /></span><span style="font-size: 10pt;">Imris president and CEO Jay D Miller states that the company estimates the volume will be almost 17,000 by the end of 2014, an increase of around 31% in one year over the previous eight years.<br /><br /></span><span style="font-size: 10pt;">&ldquo;With increasing adoption and utilisation, more neurosurgeons and hospitals are recognising the decision support advantage of enhanced visualisation in the intraoperative setting and reduced risks associated with not moving patients for imaging,&rdquo; he says.</span></p> <p><span style="font-size: 10pt;"><br /></span><span style="font-size: 10pt;">&ldquo;The top neurosurgical hospitals are making the Imris solution their standard of care and not only increasing the number of procedures completed in the suite,&rdquo; Miller adds, &ldquo;but also expanding the types of applications and conditions other than various brain tumours, such as epilepsy, Parkinson&rsquo;s disease, stroke intervention, aneurysm, and&nbsp; Chiari malformation, and other neurological procedures using deep brain&nbsp; stimulation, ablation and other technologies with iMRI. Also, the recent addition of Visius iCT expands our solution into spinal conditions, trauma and intricate reconstructions.&rdquo;<br /><br /></span><span style="font-size: 10pt;">According to the company, inside a Visius surgical theatre equipped with either high-field iMRI or&nbsp; 64-slice intraoperative computed tomography (iCT), surgeons have&nbsp; on-demand access to real-time data and imaging, during&nbsp; the procedure from the operating room table. The MRI and CT imaging solution are said by the company to move on ceiling-mounted rails to enter or exit the operating room which mitigates known risks of moving critically-ill patients.<br /><br /></span><span style="font-size: 10pt;">Surgeons using iMRI for brain tumour removal have reported outcomes of more complete resection and reduced paediatric re-operation rates. Data published in 2011 shows 93% of iMRI glioma cases achieved gross or near total resection compared to 65% for non-iMRI cases in the same timeframe.

The test is said to detect cognitive decline in patients by scoring attention/reaction and learning/memory and comparing the scores to traditional cognitive impairment indicators</span></strong><br /><br /></span><span style="font-size: 10pt;">To detect the early signs of mild cognitive impairment which may lead to forms of dementia, including Alzheimer&rsquo;s disease, there is a need for a standardised test that can alert physicians to a possible cognitive decline, it says in a press release. Recent research from the Florey Institute of Neuroscience and Mental Health in Australia reported that a brief, online set of cognitive tests (</span><span style="font-size: 10pt;">Cognigram</span><span style="font-size: 10pt;">; Cogstate) can detect early signs of mild cognitive impairment and Alzheimer&rsquo;s.<br /><br /></span><span style="font-size: 10pt;">According to the release, Cognigram is available to primary-care physicians to provide a dementia test at the point of care in Canada through an exclusive agreement with Merck Canada. More than 580 primary care physicians have registered to use Cognigram and 20 testing centres are now live.<br /><br /></span><span style="font-size: 10pt;">To evaluate the functional health of a human brain, there needs to be observation of performance on several key domains, it states in the release. To assess the state of sub cortical brain regions including the basal ganglia as well as cortical regions such as the prefrontal and parietal cortices, tests of attention and reaction time are used. Learning and working memory depend on normal functioning of the hippocampus and temporal lobe (for pattern separation) and prefrontal cortex and anterior cingulate (for working memory).<br /><br /></span><span style="font-size: 10pt;">By grouping these two domains, attention/reaction and learning/memory, into composite scores, the research team, led </span><span style="font-size: 10pt;">Paul Maruff</span><span style="font-size: 10pt;">, chief science officer of Cogstate, were able to compare test results with traditional indicators of mild cognitive impairment and Alzheimer&rsquo;s.<br /><br /></span><span style="font-size: 10pt;">&ldquo;The presence of a relatively greater impairment in cognitive functions dependent on cortical and limbic brain regions (i.e. learning and working memory) with relatively subtle impairment in motor and attention functions is consistent with neuropsychological models of Alzheimer&rsquo;s disease which emphasise that cognitive impairment characteristic of both prodromal and clinically classified Alzheimer&rsquo;s disease is disruption to memory and executive function,&rdquo; says Maruff.<br /><br /></span><span style="font-size: 10pt;">To test this, they recruited volunteers from the <a href="http://www.aibl.csiro.au/" target="_blank">AIBL</a> (Australian imaging, biomarkers and lifestyle) study, dividing them into three groups; 653 healthy adults, 107 with amnesic mild cognitive impairment (where the primary symptom is memory loss), and 44 with Alzheimer&rsquo;s disease. They were all asked to complete the four tests of the Cogstate brief battery (also known as&nbsp;</span><span style="font-size: 10pt;">Cognigram</span><span style="font-size: 10pt;">), and the speed and accuracy of the results were recorded.<br /><br /></span><span style="font-size: 10pt;">All of the Cogstate tests use a deck of playing cards as their focus point. No knowledge of any card games is required, patients answer a yes/no question about what and when cards are shown to them. For the attention/reaction composite, volunteers completed a&nbsp;</span><span style="font-size: 10pt;">detection</span><span style="font-size: 10pt;">&nbsp;task, pressing a certain key on a computer keyboard as soon as a card is turned over, as well as an&nbsp;</span><span style="font-size: 10pt;">identification</span><span style="font-size: 10pt;">&nbsp;task, answering yes or no if a card turned over is the colour red.<br /><br /></span><span style="font-size: 10pt;">For the learning/working memory composite, two additional tests were used. The&nbsp;</span><span style="font-size: 10pt;">one-card learning</span><span style="font-size: 10pt;">&nbsp;task asks, &ldquo;Have you seen this card before in this task?&rdquo; To test immediate recall, the&nbsp;</span><span style="font-size: 10pt;">one back</span><span style="font-size: 10pt;">&nbsp;test asks if the card displayed is the same as the immediately prior card.<br /><br /></span><span style="font-size: 10pt;">The results showed that both the mild cognitive impairment and the Alzheimer&rsquo;s disease groups performed significantly worse on both composites than the healthy adults. Also, the Alzheimer&rsquo;s group&rsquo;s learning/memory score was significantly lower than the cognitive impairment group, demonstrating the presence and progression of the memory decline caused by the disease.<br /><br /></span><span style="font-size: 10pt;">To be a reliable diagnostic tool for physicians, it says in the release, the test battery needs to be able to show consistent results over time. The Cognigram testing was repeated four times in three months and showed statistically similar results across all groups.</span></p> <p><span style="font-size: 10pt;"><br /></span><span style="font-size: 10pt;">&ldquo;We are excited about the results of this study,&rdquo; comments Maruff. &ldquo;The Cogstate brief battery has been found to be sensitive to amyloid-related cognitive change in many trials. This study shows for the first time, that a version of the test designed specifically for clinical practice; the Cognigram battery, has excellent sensitivity and specificity to mild cognitive impairment.&rdquo;</span></p></div> Richard Hammond backs children’s brain injury book launch http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/richard-hammond-backs-childrens-brain-injury-book-launch 2014-01-16T10:11:00Z 2014-01-16T10:11:00Z <div id="ImageMain90" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/richard-hammond-backs-childrens-brain-injury-book-launch"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/034/Richard-Hammond-web_Main.jpg" border="0" vspace="5" /></a></div><div id="Text190" style="clear:both; text-align:left"><p><span style="font-size: 10pt;"><strong><span style="font-size: 11pt;">Top Gear presenter Richard Hammond is backing the launch of a book launch aimed at helping youngsters and their parents to better understand brain injuries and their hidden effects, it was reported in a press release from the Children&rsquo;s Trust</span></strong><br /><br /></span><span style="font-size: 10pt;">According to the release, Hammond suffered a serious brain injury when he was involved in a high speed car crash.

Raising urate levels also was found to be neuroprotective in pre-clinical models of the disease.<br /><br /></span><span style="font-size: 10pt;">Parkinson&rsquo;s patients should not self medicate with inosine (which is commercially available), researchers warn, as it has not been proven as a therapy for Parkinson&rsquo;s and high doses can cause side-effects such as gout and kidney stones and possibly high blood pressure. According to a press release, more research into inosine is needed to characterise the effect on Parkinson&rsquo;s and, if positive, define dosage and treatment regimens.<br /><br /></span><span style="font-size: 10pt;">&ldquo;We intend to find out whether inosine can be used as a protective therapy to delay Parkinson&rsquo;s in people at risk and slow disease progression in those already diagnosed,&rdquo; says lead investigator Michael Schwarzschild, Massachusetts General Hospital, Boston, USA. &ldquo;Such a disease-modifying therapy is a critical goal of Parkinson&rsquo;s disease research, and would greatly improve quality of life and prognosis for the millions living with this disease&rdquo;.<br /><br /></span><span style="font-size: 10pt;">Schwarzschild also cites the potential of urate as a biomarker. Learning more about how urate levels present in different stages of Parkinson&rsquo;s could help researchers to identify people at higher risk of the disease, who may benefit from earlier intervention and therefore stratify clinical trials toward individuals with higher likelihood to respond to the treatment.<br /><br /></span><span style="font-size: 10pt;">The Michael J Fox Foundation invested more than US$5 million in SURE-PD in 2008.</span></p> <p><span style="font-size: 10pt;"><br /></span><span style="font-size: 10pt;">The SURE-PD investigators call for &ldquo;the development of a more definitive trial to investigate the ability of inosine treatment to slow clinical progression among persons with early Parkinson&rsquo;s disease who have lower urate&rdquo;.</span></p></div> Apeiron signs regional license agreements for the commercialisation of a neuroblastoma therapy http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/apeiron-signs-regional-license-agreements-for-the-commercialisation-of-a-neuroblastoma-therapy- 2014-01-14T11:18:00Z 2014-01-14T11:18:00Z <div id="Text199" style="clear:both; text-align:left"><p><span style="font-size: 10pt;"><span style="font-size: 11pt;"><strong>Apeiron has announced the signing of two transactions as part of the worldwide commercialisation of APN311, an antibody-based immunotherapy in development for the treatment of children suffering from high-risk neuroblastoma</strong></span><br /><br /></span><span style="font-size: 10pt;">Apeiron announced the signing of license agreements with Medison and Gen Ilac.

The study will include the monitoring of neurological patients, as a prelude to possible future use with astronauts</strong></span><br /><br /></span><span style="font-size: 10pt;">Some astronauts are developing serious visual impairment conditions with associated symptoms suggestive of elevated pressure on the brain, or increased intracranial pressure the study says. NSBRI, a non-profit entity funded by NASA, has partnered with Vittamed to independently evaluate their proprietary Vittamed 205 device that can non-invasively measure absolute intracranial pressure without the need of patient-specific calibration. &ldquo;We believe that the Vittamed device holds great promise as a reliable method to non-invasively assess intracranial pressure in astronauts as well as in patients that require monitoring on Earth,&rdquo; says Dorit Donoviel, NSBRI&rsquo;s deputy chief scientist and industry forum lead.<br /><br /></span><span style="font-size: 10pt;">NSBRI is sponsoring the clinical validation and operational evaluation study, led by Eric Bershad, a neuro-intensivist and vascular neurologist at&nbsp;Baylor College of Medicine&nbsp;and St Luke&rsquo;s Medical Center, Houston, USA. &ldquo;Currently, the only reliable way to monitor intracranial pressure is to place a catheter into the brain or cerebrospinal fluid space.&nbsp;Therefore, there is an urgent need to develop non-invasive devices for measuring this important indicator of brain health,&rdquo; comments Bershad.<br /><br /></span><span style="font-size: 10pt;">The Vittamed device was selected by NSBRI after a worldwide search for non-invasive intracranial pressure technologies. &ldquo;This is a very important step for Vittamed and we are pleased that NSBRI decided to move forward with a clinical research study of our innovative device,&rdquo; says Vittamed&rsquo;s CEO&nbsp;Remis Bistras.<br /><br /></span><span style="font-size: 10pt;">The study was initiated in September 2013 and is due to conclude in mid-2014. Vittamed Corporation is providing equipment, training, and expert technical advice. Intracranial pressure measurements obtained using the Vittamed 205 device are being compared with simultaneous lumbar puncture readings, which are considered the gold standard in patients undergoing evaluation for medical reasons. A total of 40 patients will participate in the study. The&nbsp;Houston&nbsp;team is also evaluating the device for its suitability in assessing the astronauts&rsquo; intracranial pressure in the space environment.<br /><br /></span><span style="font-size: 10pt;">The technology, according to a press release, was initially developed to target patients suffering from traumatic brain injuries, concussions, neurological diseases, hydrocephalus and other complications. &ldquo;We are thrilled that our technology will help not only clinical patients, but also astronauts, and therefore aid the advancement of space research,&rdquo; said&nbsp;Arminas Ragauskas, Vittamed&rsquo;s chief technology officer, professor at Kaunas University of Technology, Kaunas, Lithuania, and inventor of the technology.</span></p></div>
