It received US Food and Drug Administration (FDA) approval in 2011 only to treat patients with recurring glioblastoma, not first-time cases.</span><br /><br /></p> <p><span style="font-size: 10pt;">The manufacturer, Novocure, is currently seeking FDA approval to use the device on all glioblastoma patients. Marketed under the brand name Optune, the equipment creates low-intensity alternating electric fields, referred to as tumour treating fields, and delivers them through wires attached to the patient&rsquo;s shaved scalp by four adhesive transducer pads that target the brain tumour. Individual placement of the transducers is determined by MRI scan. The clinical trials showed that the tumour treating fields reversed the tumour&rsquo;s growth and killed cancer cells by disrupting mitosis, the process by which cells divide and replicate.</span><br /><br /></p> <p><span style="font-size: 10pt;">Research results were presented by the study&rsquo;s leader Roger Stupp, chairman of the oncology department at Switzerland&rsquo;s University of Zurich, at the annual meeting of the Society for Neuro-Oncology in Miami, USA. Data collected from the first 315 of around 700 patients included in the international clinical trials showed:</span></p> <ul> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Patients treated with both tumour treating fields and temozolomide chemotherapy showed a &ldquo;significant increase&rdquo; in progression-free survival compared to those treated with chemotherapy alone - a median of 7.1 months compared to 4 months;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Those treated with both tumour treating fields and temozolomide also showed a &ldquo;significant increase&rdquo; in overall survival compared to temozolomide alone - a median 19.6 months compared the 16.6 months.</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 43% of patients treated with both tumour treating fields and temozolomide chemotherapy were still alive after 2 years compared to 29% treated with the chemotherapy alone.</span><br /><br /></li> </ul> <p><span style="font-size: 10pt;">The only side effect reported by the researchers was irritation of the scalp where the transducers were attached. &ldquo;These results are spectacular, a lot better and much more convincing than we ever would have dreamt of,&rdquo; says Stupp.</span></p></div> Barrow neurosurgeons implant the world’s first scaffold into a patient’s spinal cord 2014-11-21T10:19:00Z 2014-11-21T10:19:00Z <div id="Introduction2" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Neurosurgeons at Barrow Neurological Institute have implanted the world&rsquo;s first scaffolding device into the spinal cord of a patient.&nbsp;Performed last month, the surgery involves inserting a bioresorbable scaffolding implant to act as a bridge across the gap of the injured section of the cord in an attempt to help the spinal cord heal.</strong></span></p> </div><div id="Text12" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">This first case is part of a pilot study to measure the clinical safety of the implanted device developed by InVivo Therapeutics. &ldquo;This could be the first step in identifying a new treatment option to improve the overall recovery of individuals with acute spinal cord injury,&rdquo; says Nicholas Theodore, chief of spinal surgery at Barrow and principal investigator of the study.</span></p> <p><span style="font-size: 10pt;">Twenty-five-year-old Jordan Fallis, the first patient to have the scaffold implanted, will be closely monitored throughout his recovery to see if there are any changes or improvements to his spinal cord and mobility. A section of Fallis&rsquo; spinal cord was injured in a dirt biking accident and he was airlifted to Barrow which is located at Dignity Health St Joseph&rsquo;s Hospital and Medical Center, where he underwent emergency surgery that evening. Fallis spent a week in the ICU before being transferred to the hospital&rsquo;s Neuro Rehabilitation Center where he is currently undergoing intensive physical and occupational therapy.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;I&rsquo;m excited to be the first patient in this research study that may one day become the standard of spinal cord injury treatment,&rdquo; says Fallis.</span><br /><br /></p> <p><span style="font-size: 10pt;">To measure the safety of the device, the US Federal Drug Authority has approved five individuals in the USA&nbsp;to undergo the procedure. Fallis will be monitored for three months before InVivo reopens enrolment. In addition to Barrow, the University of North Carolina, the University of Arizona and the Washington University Medical Center are participants in the study.</span></p></div> FDA clears Ahead 100 device for adjunctive assessment of traumatic brain injury 2014-11-20T15:30:00Z 2014-11-20T15:30:00Z <div id="Introduction3" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>BrainScope&nbsp;has announced that the United States Food and Drug Administration (FDA) has cleared the company&rsquo;s Ahead&nbsp;100 device through the&nbsp;<em>de novo</em>&nbsp;classification process. The Ahead&nbsp;100 uses a patient&rsquo;s electroencephalograph (EEG) to provide an interpretation of the structural condition of the patient&rsquo;s brain after head injury.</strong></span></p> </div><div id="Text13" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">It is indicated for use as an adjunct to standard clinical practice to aid in the evaluation of patients who are being considered for a head computerised tomography (CT) scan, but should not be used as a substitute for a CT scan. It is to be used on patients who sustained a closed head injury within 24 hours, clinically present as a mild traumatic brain injury, and are between the ages of 18-80 years.</span></p> <p><br /><span style="font-size: 10pt;"> &ldquo;Each year there are approximately two million patients in the United States alone who sustain head injuries and go to Emergency Departments for evaluation,&rdquo; states J Stephen Huff, associate professor of Emergency Medicine and Neurology at the University of Virginia School of Medicine and the clinical principal investigator of the B-AHEAD II trial. &ldquo;Many of these patients present with very mild symptoms, yet may have life-threatening bleeds in the brain. An objective, accurate capability that can rapidly help identify and categorise patients with even the mildest forms of brain injury could help save lives, reduce radiation exposure, and decrease costs to the healthcare system. The performance and clinical utility of the Ahead&nbsp;100 is superior to that of standard of practice tools. Also, the possibility of reduction of use of neuroimaging in patients with head injury is consistent with the&nbsp;<em>Choosing Wisely</em>&nbsp;campaign sponsored by several professional organisations.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> &ldquo;This is a landmark event in the assessment of head injury,&rdquo; adds Daniel Hanley, the Jeffrey &amp; Harriet Legum professor of Acute Care Neurology at Johns Hopkins University, director of the Johns Hopkins Brain Injury Outcomes Services division, and Medical Advisory Board member to BrainScope. &ldquo;I am greatly impressed by the performance of the Ahead&nbsp;100 for discriminating clinically important mild traumatic brain injury and believe this device is a practical, safe and transformative adjunct to acute CT scan.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> The BrainScope Ahead&nbsp;100 has been developed over six years of technology development and clinical studies at hospital Emergency Rooms across the USA, creating an extensive database of head injured patients. &ldquo;Using sophisticated classification algorithm methods we sought neurophysiological profiles or signatures of changes in brain electrical activity associated with traumatic structural brain injury,&rdquo; explains Leslie Prichep, director of the Quantitative Neurophysiological Brain Research Laboratories at the NYU School of Medicine and consultant to BrainScope. &ldquo;One of the most important findings was the extremely high performance of the Ahead&nbsp;100 to identify the absence of structural brain injury after a patient has sustained a head injury. This provides important information to the clinician, contributing to a rule-out for one of the most prevalent concerns clinicians have with mildly presenting patients.&rdquo;</span></p></div> Specialised ambulance increases thrombolysis for stroke patients in ‘golden hour’ 2014-11-19T09:40:00Z 2014-11-19T09:40:00Z <div id="ImageMain4" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction4" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A specialised ambulance staffed with a neurologist and equipped with a computed tomographic scanner helped increase the percentage of patients with stroke who received thrombolysis to break down blood clots within the so-called &lsquo;golden hour,&rsquo; the 60 minutes from time of symptom onset to treatment when treatment may be most effective, according to a study published online by <a href="" target="_blank"><em>JAMA Neurology</em></a>.</strong></span></p> </div><div id="Text14" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The time to treatment with tissue plasminogen activator (tPA) to break down blood clots is crucial to how patients fare after acute ischaemic stroke. But when pre-hospital times are added to hospital delays the onset to treatment (OTT) within 60 minutes seems out of reach for most patients. An approach to shorten the OTT is pre-hospital thrombolysis in a specialised ambulance, according to background information in the study.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Martin Ebinger of the Charit&eacute;-Universit&auml;tsmedizin Berlin, Germany, and co-authors examined the achievable rate of golden hour thrombolysis in pre-hospital care and the effect it had on how patients fared. The authors used data from a study conducted in Berlin where weeks were randomised according to the availability of a stroke emergency mobile unit (STEMO) from May 2011 through January 2013.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Study results indicate there were 3,213 emergency calls for suspected stroke during weeks when STEMO was available and 2,969 calls during control weeks when STEMO was not available. Overall, 200 of 614 patients with stroke (32.6%) received thrombolysis when the STEMO was deployed and 330 of 1,497 patients (22%) received thrombolysis in conventional care. Median OTT was 24.5 minutes shorter after STEMO deployment compared with conventional care. In all ischaemic strokes, the rate of golden hour thrombolysis increased from 16 of 1,497 patients (1.1%) during conventional care to 62 of 614 (10.1%) after STEMO deployment. The median OTT was 50 minutes in golden hour thrombolysis vs. 105 minutes in all other thrombolysis. Patients with golden hour thrombolysis had no higher risks for seven- or 90-day mortality compared with patients with longer OTT and were more likely to be discharged home.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The use of STEMO increases the percentage of patients receiving thrombolysis within the golden hour. Golden hour thrombolysis entails no risk to the patients&rsquo; safety and is associated with better short-term outcomes,&rdquo; the study notes.</span></p> <p><span style="font-size: 10pt;"><strong>&nbsp;</strong></span></p> <p><span style="font-size: 10pt;"><br />In a related editorial, Steven Warach of the University of Texas Southwestern Medical Center, Austin, USA, writes: &ldquo;There is no doubt that, in Berlin, STEMO significantly shortened the time to thrombolytic treatment, which may translate to clinical benefits. Let there also be no doubt that the mobile stroke unit is here to stay and is starting to disseminate into pre-hospital stroke care. Many questions need to be answered in order to determine the appropriate niche where the benefit justifies the intensive use of resources that this approach requires. It is the duty of the early adopters to resist the temptation to uncritically embrace this approach as a certain good and to address these issues through rigorous clinical investigations.&rdquo;</span></p></div> MR CLEAN: expert opinion 2014-11-18T11:31:00Z 2014-11-18T11:31:00Z <div id="ImageMain5" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction5" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Since the first presentation of data at the World Stroke Congress, the MR CLEAN trial has sent a ripple across the entire neurointerventional arena, raising questions about the future of stroke treatment and the fate of similar trials, some of which have already been halted.</strong></span></p> </div><div id="Text15" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">At the Society of Vascular and Interventional Neurology meeting (SVIN) the as yet unpublished MR CLEAN (Multicentre randomised clinical trial of endovascular treatment for acute ischaemic stroke in the Netherlands) results were discussed by an expert panel. The panel, including Jeffrey Saver, Tudor Jovin, Osama Zaidat, Italo Linfante, Raul Nogueira, and Dileep Yavagal, focused on the effect of the trial results on other trials and where that leaves clinical practice going forward.&nbsp;</span></p> <p><br /><span style="font-size: 10pt;"> MR CLEAN is a pragmatic phase III multicentre randomised clinical trial with blinded outcome assessment. Endovascular treatment (intra-arterial thrombolysis, mechanical treatment or both) was compared with no treatment, against a background of optimal medical management, with or without intravenous alteplase. With the enrolment of 500 patients complete, the results presented at World Stroke Congress were in favour of interventional treatment.</span></p> <p><br /><span style="font-size: 10pt;"> Jeffrey Saver, who was present at the World Stroke Congress, gave a brief summary of MR CLEAN: &ldquo;MR CLEAN had a very broad design. They could enrol patients who were getting t-PA or not getting t-PA as the background therapy up to six hours after onset. They had broad clinical criteria&mdash;NIHSS score of two or higher. Patients had to have an occlusion in the terminal ICA, in the M1 M2 or in the A1 A2. Even though they were broadly inclusive and started in the pre-stent retriever era, most of the patients (97%) were treated with retrievable stents, so MR CLEAN is basically a stent retriever trial. The average time from onset to t-PA was under 90 minutes, but the average time from onset to randomisation was 200 minutes. Because there was 110 minutes between t-PA start and randomisation, they ended up with t-PA failure patients. Onset to groin puncture was 60 minutes faster than some of the prior studies. Serious adverse events were not greatly different between the two groups. In terms of results, in the onset to randomisation, whether patients were randomised early or late, within the first two hours or beyond the first two hours, they benefited, so two hours is not a key cut point.&rdquo;</span></p> <p><strong><br /> <br /> </strong></p></div><div id="Text25" style="clear:both; text-align:left"><p><span style="font-size: 10pt;"><strong>Way forward</strong></span></p> <p><br /><span style="font-size: 10pt;"> The question was then raised: with MR CLEAN and similar trials such as ESCAPE and EXTEND IA declared positive, what is the next step? &ldquo;Are we done with our trials; can we just go into clinical practice and not have to worry about anything yet?&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> Saver responded that just looking at the results of MR CLEAN, the answer is no. He pointed to the fully able to return to work/non-disabled outcome which reportedly showed that 88% of patients in the intervention arm are still unable to return to work and 97% of patients still have symptoms from their stroke. &ldquo;So there is still a huge need for additional therapies. We have had a major step forward but we need to keep doing better, and so we need to move on to the next generation of trials.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> As for the process of making decisions for other trials based on data that are yet to be published, the expert panel maintained that care must be taken.</span></p> <p><br /><span style="font-size: 10pt;"> Tudor Jovin cautioned, &ldquo;We must remember that these results are in non-published form; we do not know how these results are going to look in their definitive form. The same applies to ESCAPE. Before ESCAPE we could have said that this could be an outlier, but to me, the fact that ESCAPE was stopped due to crossing pre-defined efficacy boundaries tells me that this probably is the kind of treatment effect that we are looking at. So I suspect the data are real and because of that I have no reason to believe that other ongoing trials are not going to go the same direction. The question to me is less &lsquo;should the trials be stopped&rsquo;, and more, &lsquo;should consenting be changed&rsquo;, because for all of these reasons you can make a good argument that trials should not be stopped. The question is &lsquo;how do we incorporate this kind of information into the consenting process&rsquo;.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> Following on from Jovin, Raul Nogueira stated, &ldquo;Equipoise is not what we [personally] think, it is about what the whole medical community thinks, and we do not know if things are going to change, and stopping before things change would be a mistake. We have duties to the patient in front of us and to the whole community of patients we will see for the rest of our lives. It is a complicated ethical dilemma, I think we need to measure the degree of equipoise in the whole community, and I think the trials should probably be put on hold as opposed to stopped.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> Up to time of publication, the ESCAPE trial has been permanently halted, the SWIFT-PRIME trial has been temporarily halted, and the REVASCAT trial continues to enrol, with a scheduled pre-planned analysis due in the near future.</span></p></div> Majority of UK neurosurgical units following published recommendations, but room for improvement remains 2014-11-18T11:00:00Z 2014-11-18T11:00:00Z <div id="ImageMain6" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction6" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>It has been discovered via a national survey of current practice that six months post-publication of the National Confidential Enquiry into Patient Outcome and Death report, the majority of neurosurgical units across the United Kingdom and Ireland have been following most of the key recommendations for the management of aneurysmal subarachnoid haemorrhage.</strong></span></p> </div><div id="Text16" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Study authors Othman Al-Helli <em>et al</em> report in the <a href="" target="_blank"><em>Journal of Neurointerventional Surgery</em></a> however, that in the remainder of neurosurgical units they found variability in clinical practice.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />According to the authors, the management of aneurysmal subarachnoid haemorrhage has undergone extensive change in recent years with the publication of recommendations and guidelines by specialty bodies. The National Confidential Enquiry into Patient Outcome and Death report and recommendations were published in November 2013 as a follow-up to the 2012 recommendations for the management of aneurysmal subarachnoid haemorrhage published by the Royal College of Physicians and the American Heart Association/American Stroke Association. The aim of Al-Helli <em>et al&rsquo;s</em> study was to assess how many of these recommendations were being followed six months after the latest publication, and to compare current practice with the National Confidential Enquiry into Patient Outcome and Death data collected in 2011.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />To carry out their investigation, study authors formulated a survey composed of 19 questions regarding the management of aneurysmal subarachnoid haemorrhage, and conducted a telephone interview with the neurosurgical registrars on call. The 19 questions covered six areas: hospital policies and facilities for treatment of aneurysmal subarachnoid haemorrhage; medical measures to prevent rebleeding; surgical and endovascular methods of treatment; management of cerebral vasospasm and delayed cerebral ischaemia; management of hydrocephalus; and management of medical complications. Thirty neurosurgical units participated in the survey. The results were then compared against currently available published recommendations.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />According to the results, &ldquo;22 out of the 30 centres aimed to treat ruptured aneurysms by coiling or clipping within 48 hours of ictus, yet only 15 units offered regular weekend interventional neuroradiological treatment. In nine units, all aneurysmal subarachnoid haemorrhages were routinely discussed in a multidisciplinary meeting.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The authors note: &ldquo;In the vast majority of neurosurgical centres, the main recommendations from the Royal College of Physicians, the American Heart Association/American Stroke Association, and the National Confidential Enquiry into Patient Outcome and Death report were being followed. Given data from previous studies over the past 15 years suggesting a longer interval to securing a ruptured intracranial aneurysm compared with other developed countries such as the USA, this survey suggests that there has been improvement in the service in the UK.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />They conclude noting that while there appears to be recent considerable improvement in the management of aneurysmal subarachnoid haemorrhage in the UK, more work is required before care delivery is optimised. They further state their intention to repeat the survey in the future to assess the progress made.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Al-Helli told <em>NeuroNews</em>: &ldquo;The most concerning finding of the study is the fact that only half of the neuroscience centres provide weekend neurointerventional service despite the guidelines recommend very clearly that early treatment not later than 48 hours post-ictus is a key factor for better outcome. I believe that our findings imply that patients who their bleed on a Friday night will have worse outcome that those who have it on any other weekday.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Commenting on what might be done to improve outcomes, he added, &ldquo;Providing a six day service might help. I personally wish that neither myself or any friend or family or indeed anybody get their bleed on a Friday night. Otherwise they might have to wait more than 48 hours to secure aneurysm preventing the potentially disastrous complication of rebleeding!&rdquo;</span></p></div> CE mark for new Asahi Intecc neurovascular guide wires 2014-11-17T14:36:00Z 2014-11-17T14:36:00Z <div id="ImageMain7" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction7" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Asahi Intecc has received CE certification of neurovascular guide wires: Asahi Chikai 008, Asahi Chikai black, and Asahi Chikai black 18 and is initiating sales in Europe.</strong> </span></p> </div><div id="Text17" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">According to the company, the above wires join the currently marketed Asahi Chikai and Asahi Chikai 10 in incorporating Asahi Intecc&rsquo;s unique Actone technology, which provides improved torque performance, shape retention and support.

Recent results from a 500-patient, multicentre, randomised European ischaemic stroke trial (<a href="">MR CLEAN</a>), presented at the 9th World Stroke Congress in Istanbul, Turkey, revealed that direct vascular intervention (97% used retrievable stents) generated better outcomes than standard stroke therapy alone. The study also demonstrated that, despite generating better outcomes for patients, there is still room for improvement in vascular intervention. Clot particles were lost during interventional procedures, resulting in an ischaemic stroke to a new region of the brain 5.6% of the time, vs. 0.4% of the time in the control (ie., standard therapy) group.</span></p> <p><br /><span style="font-size: 10pt;">Lazarus Effect plans to launch the Lazarus Cover, which can be used with a variety of available retriever devices, in Europe during Q1 2015.</span></p> <p><br /><span style="font-size: 10pt;">The US Patent and Trademark Office recently issued a new patent covering core technology behind the Lazarus Cover, as well as the Lazarus ReCover device.

The Certified Treatment Centers of Excellence both extend and improve the quality of life for those living with ALS, and actively participate in ALS-related research.</p> <p>Earlier this month, the ALS Association announced it was supporting six different programmes and initiatives designed to expedite the search for treatments and a cure for ALS. Four of these projects involve global research cooperative alliances that would not have moved forward without the funding from the ALS Association and the matching donations it received.<br /><br /></p> <p>In addition, the Association launched a new collaborative initiative that will bring the ALS community together to establish an ALS drug development guidance document. No such document currently exists, which creates uncertainty and risk for what already is a difficult, lengthy and costly process. The Association hopes that this initiative will incentivise ALS drug development, reduce obstacles and provide new opportunities to accelerate research and bring new treatments forward.</p></div> NeuroSigma receives notice of allowance for subcutaneous trigeminal nerve stimulation patent 2014-11-04T15:51:00Z 2014-11-04T15:51:00Z <div id="ImageMain11" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction11" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>NeuroSigma has announced that the Mexican Institute of Industrial Property has issued a Notice of Allowance for Mexican Patent Application No. MX/a/2012/004051.

The flexibility of the CyberKnife system enabled by its unique architecture allows tumour control while preserving vision. The results Conti presented in a plenary session included a series of 64 patients with perioptic meningiomas treated in 2-5 fractions with CyberKnife schemes from July 2007&ndash;May 2010.</span><br /><br /></p> <p><span style="font-size: 10pt;">The study included two cohorts of patients with different tumour volumes. In one cohort, 25 patients with a small tumour volume (less than 5cc) were followed for an average of 60 months (+12 months). In the second cohort, 39 patients with a larger tumour volume (7.5cc) were followed for an average of 17 months (+10 months). No visual deterioration was observed and tumour control was achieved in all cases.</span><br /><br /></p> <p><span style="font-size: 10pt;">These results support the clinical benefits of CyberKnife treatment for perioptic meningiomas, and were achieved thanks to the ability to fractionate depending on the tumour volume and its proximity to the optic nerve.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;The CyberKnife robotic radiosurgery system is able to treat safely and efficiently tumours with large volumes, in particular meningiomas, as well as acoustic neuromas,&rdquo; says Alfredo Conti. &ldquo;This is a real breakthrough because treating large tumours with radiosurgery in a single fraction is very challenging, and often not possible. Furthermore, treating tumours close to the optic nerves or other critical brain structures is sometimes very challenging for neurosurgeons and the CyberKnife system represents a safer and effective treatment option.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">A second study done by Pantaleo Romanelli, CyberKnife Center, Centro Diagnostico Italiano, Milan, Italy, evaluated the clinical benefits of the CyberKnife system as a treatment for patients with trigeminal neuralgia. A cohort of 103 patients was treated with a 60 Gy dose delivered in a single fraction by the CyberKnife system.</span><br /><br /></p> <p><span style="font-size: 10pt;">Results indicate that use of the CyberKnife system provides a safe and effective treatment option for people with trigeminal neuralgia. After six months, more than 90% of patients showed significant improvement in their symptoms. The system also provided an opportunity to successfully retreat 24 patients who had relapsed within two years from their first treatment.</span><br /><br /></p> <p><span style="font-size: 10pt;">Finally, at the Accuray symposium held in Prague at the 15th EANS congress, Alexander Muacevic, director of the Europ&auml;isches CyberKnife Zentrum in Munich, Germany, presented the extension of indications, such as spinal tumours, treated with the CyberKnife system. &ldquo;The CyberKnife robotic radiosurgery system is safe and effective in the treatment of spinal lesions.

The Centers for Disease Control and Prevention says that Americans 55 years and older account for more than 60% of all hospitalisations for traumatic brain injury, with the highest rates of traumatic brain injury-related emergency department visits, inpatient stays and deaths happening among those patients 75 years and older. Therefore, understanding the effects of a recent traumatic brain injury and the subsequent development of dementia among middle or older adults has important public health implications.</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers Raquel C Gardner, of the University of California, San Francisco, and colleagues examined the risk of dementia among adults 55 years and older with recent traumatic brain injury compared with adults with non- traumatic brain injury body trauma, which was defined as fractures but not of the head or neck. The study included 164,661 patients identified in a state-wide California administrative health database of emergency department and inpatient visits.</span><br /><br /></p> <p><span style="font-size: 10pt;">In the study, a total of 51,799 patients with trauma (31%) had traumatic brain injury. Of those, 4,361 patients (8.4%) developed dementia compared with 6,610 patients (5.9%) with non-traumatic brain injury body trauma. The average time from trauma to dementia diagnosis was 3.2 years and it was shorter in the traumatic brain injury group compared with the non- traumatic brain injury group (3.1 vs 3.3 years). Moderate to severe traumatic brain injury was associated with increased risk of dementia at 55 years or older, while mild traumatic brain injury at 65 years or older increased the dementia risk.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Whether a person with traumatic brain injury recovers cognitively or develops dementia, however, is likely dependent on multiple additional risk and protective factors, ranging from genetics and medical comorbidities to environmental exposures and specific characteristics of the traumatic brain injury itself,&rdquo; the authors note.</span><br /><br /></p> <p><span style="font-size: 10pt;">Steven T DeKosky, of the University of Pittsburgh School of Medicine, writes: &ldquo;Unfortunately, there was not a non-trauma control group included, which may have answered the question of whether non-traumatic brain injury body trauma raised the risk of dementia significantly above age-equivalent controls without non-brain trauma (perhaps from inflammation or other complications).&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Judicious use of data by skilled researchers who are familiar with the entire range of dementia research from pathobiology to healthcare needs will enable us to ask important questions, evolve new or more informed queries, and both lead and complement the translational questions that are before us.

Thus, health care providers would potentially have a novel means to treat patients of neurological injury in which the blood brain barrier is compromised, such as stroke, by systemically administering TB4 to accelerate repair and regenerate damaged brain tissue.&nbsp;</span></p></div> The Roskamp Institute discovers new target for drugs to treat Alzheimer&apos;s disease 2014-10-27T17:12:00Z 2014-10-27T17:12:00Z <div id="ImageMain20" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction20" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Published in the online edition of the <em><a href="">Journal of Biological Chemistry</a></em>, the results of the extensive studies offer a new target for drug development in the quest for a cure for Alzheimer&rsquo;s, the most prevalent form of dementia in the elderly.&nbsp;</strong></span></p> </div><div id="Text120" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The Roskamp researchers have identified a single enzyme which propagates the three key hallmarks of Alzheimer&rsquo;s disease &ndash; inflammation, accumulation of amyloid protein, and modulation of the &rsquo;tau&rsquo; protein, all of which are responsible for damage to the nerve cells of the brain.<br /><br /></span></p> <p><span style="font-size: 10pt;">&ldquo;These studies suggest there is a single drug target to inhibit all the three key pathologies of Alzheimer&rsquo;s disease,&rdquo; says neurobiologist Daniel Paris, lead researcher for the study.<br /><br /></span></p> <p><span style="font-size: 10pt;">Michael Mullan, senior author of the published study, adds, &ldquo;Our studies have revealed that the spleen tyrosine kinase (SYK) enzyme is at a crossroad from which all three of the brain abnormalities known to be associated with Alzheimer&rsquo;s disease diverge. Hopefully, academic or industry researchers can now develop new drugs to inhibit SYK which are suitable for clinical trials in Alzheimer&rsquo;s disease.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">In working out how an anti-hypertensive drug called Nilvadipine works to reduce amyloid protein accumulations, Roskamp researchers realized the drug also had positive effects on neuroinflammation and thetau protein. The scientists retraced the molecular steps leading to these three factors and discovered they all led back to the SYK protein.<br /><br /></span></p> <p><span style="font-size: 10pt;">Paris then went on to show that drugs blocking SYK activity in the brain could represent a new strategy for treating Alzheimer&rsquo;s. "The potential for developing a single "multi-modal" drug treatment that will control all three of these Alzheimer&rsquo;s characteristics has us very excited,&rdquo; Paris says. &ldquo;All of these pathologies are interrelated. In theory, by interrupting these three molecular pathways, we can develop more effective drugs to stop the disease.

It also found that patients experienced a greater reduction in number of attacks the longer they stayed on treatment.<br /><br /></span></p> <p><span style="font-size: 10pt;">This open-label migraine study was carried out at the Headache Centre in the Neurological Institute in Milan. The study involved thirty patients, 18 &ndash; 65, who had migraine without aura and suffered from five to nine attacks per month. Patients treated between three and six migraine episodes with gammaCore. Ninety six migraine attacks were treated by a single dose. Forty three attacks were resolved completely within 30 minutes (44.8%); for 42 (43.7%) attacks the application did not show any benefit in the first two hours so patients recurred to rescue medication; in 11 (11.4%) attacks the result was uncertain: no resolution of attack, only a moderate relief of pain. No adverse events were recorded.<br /><br /></span></p> <p><span style="font-size: 10pt;">Licia Grazzi, lead author, comments: &ldquo;The results look very promising and patients found the therapy easy to apply and it was well tolerated.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore had previously reported, at the <em><a href="">American Headache Society</a></em> that a US prevention of chronic migraine study, with a sham control arm, met its primary endpoint of safety, and demonstrated a reduction in the number of headache days per month for patients using the active device. The study suggests that patients who remain on therapy for longer periods of time, enjoy progressively larger decreases in headache days.<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore, which is running the broadest headache trial programs in the world, will report shortly on two further sham-controlled clinical studies; a US trial on the acute treatment of episodic and chronic cluster, and a European trial on the acute treatment of episodic and chronic cluster headache.<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore chief executive officer and founder JP Errico says: &ldquo;As the results of our studies continue to demonstrate positive results, we are increasingly optimistic that the extensive investment we have made in both pre-clinical trials and clinical trials was a wise use of our capital and human resources. We believe that this therapy is unique in both its safety and efficacy profiles. With few adverse events reported, non-invasive vagus nerve stimulation appears to be the first therapeutic option that offers both acute and prophylactic benefits for patients who suffer frequent and severe headaches. As such, we believe that gammaCore will ultimately move to a first line treatment for these patients, and will continue to conduct the clinical research necessary to support that conclusion.&rdquo;</span></p></div> A new window of opportunity to prevent cardiovascular and cerebrovascular diseases 2014-10-24T16:46:00Z 2014-10-24T16:46:00Z <div id="Introduction22" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in <em><a href="">JACC Cardiovascular Imaging</a></em>.</strong></span></p> </div><div id="Text122" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Mount Sinai researchers examined all relevant brain imaging studies conducted over the last 33 years. They looked at studies that used every available brain imaging modality in patients with vascular disease risk factors but no symptoms that would lead to a diagnosis of diseased blood vessels in the heart or brain, or periphery.</span><br /><br /></p> <p><span style="font-size: 10pt;">The review demonstrates that patients with high blood pressure, diabetes, obesity, high cholesterol, smoking, or metabolic syndrome, but no symptoms, still had visible signs on their neuroimaging scans of structural and functional brain changes long before the development of any events related to vascular diseases of the heart or brain.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;This is the first time we have been able to disentangle the brain effects of vascular disease risk factors from the brain effects of cardiovascular and cerebrovascular disease and/or events after they develop,&rdquo; says the article&rsquo;s lead author, Joseph I Friedman, associate professor in the Departments of Psychiatry and Neuroscience at Icahn School of Medicine at Mount Sinai. &ldquo;Moreover, subtle cognitive impairment is an important clinical manifestation of these vascular disease risk factor-related brain imaging changes in these otherwise healthy persons.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Friedman adds that, because diminished cognitive capacity adversely impacts a person&rsquo;s ability to benefit from treatment for these medical conditions, early identification of these brain changes may &ldquo;present a new window of opportunity&rdquo; for doctors to intervene early and improve prevention of advancement from vascular disease risk factors to established cardiovascular and cerebrovascular diseases. His team is currently testing these hypotheses in ongoing studies at Mount Sinai.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Patients need to start today to control their vascular risk factors, otherwise their brains may forever harbour physical changes leading to devastating heart and vascular conditions impacting their future overall health and even cognitive decline causing diseases like dementia or when it exists it can accelerate Alzheimer&rsquo;s,&rdquo; says study author, Valentin Fuster, director of Mount Sinai Heart, physician-in-chief of The Mount Sinai Hospital, and chief of the Division of Cardiology at Icahn School of Medicine at Mount Sinai. &ldquo;Our publication raises the possibility that these early brain changes are major warning signs of what the future may hold for these asymptomatic patients.

Goodhart chair in cardiology at Icahn School of Medicine at Mount Sinai. &ldquo;These subtle brain changes are clues to us physicians that our patients need to start to lower their vascular risk factors always and way before symptoms or a cardiac or brain event happens. This simple step to lower vascular risk factors can have huge impacts on global prevention efforts of cardiovascular diseases.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers identified the following impact of key vascular risk factors on the structural and functional brain health of asymptomatic patients:</span></p> <ul> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Hypertension is associated with globally appreciable brain volume reductions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Connecting brain fibre abnormalities, reduced brain blood flow and alterations in the normal pattern of synchronised brain activity between different regions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Diabetes is associated with connecting brain fibre abnormalities, reduced brain blood flow, and alterations in the normal pattern of synchronised brain activity between different regions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Obesity is associated with brain volume reductions, reduced brain blood flow and metabolism;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; High total cholesterol and low-density lipoprotein cholesterol are associated with brain volume reductions, and connecting brain fibre abnormalities.

Currently, many people with multiple sclerosis are diagnosed in an ad-hoc way and are often misdiagnosed. People with multiple sclerosis can be left for more than a year without having their condition and medication monitored.<br /><br /></span></p> <p><span style="font-size: 10pt;">An audit carried out by the Royal College of Physicians and the Multiple Sclerosis Trust in 2011 found that although some multiple sclerosis patients received excellent care from the NHS, this was not universal and there were variations in both the quality and the quantity of care provided in England and Wales.<br /><br /></span></p> <p><span style="font-size: 10pt;">In an update to the original 2003 guideline, NICE has set out how people with multiple sclerosis can receive better care. Paul Cooper, consultant neurologist at the Greater Manchester Neuroscience Centre, who chaired the NICE guideline group, says: &ldquo;The care someone receives should not depend on where they live. One of the central areas that we have tried to address in the guidance is identifying and recognising inequalities in services and in care throughout the NHS.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">Cooper continues: "In the past some people got access to prompt and appropriate treatment but many did not. Many people with multiple sclerosis were diagnosed perhaps in a rather ad-hoc way without access to specialist advice, or information and support at the time of diagnosis. Many were potentially being misdiagnosed. The other area that we have tried to address is improving access to therapies of proven benefit for this disabling and distressing condition.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">Mark Baker, director of clinical practice at NICE, comments: &ldquo;It&rsquo;s a paradigm-shifting guideline which reshapes much of our advice on multiple sclerosis and its management. It&rsquo;s a full update and it lays out a new framework for the diagnosis and management of people suspected of having multiple sclerosis.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">In the update, NICE recommends that people with suspected multiple sclerosis should be referred to a consultant neurologist. Multiple sclerosis should not be diagnosed on the basis of MRI findings alone and only a consultant neurologist should make the diagnosis of multiple sclerosis.<br /><br /></span></p> <p><span style="font-size: 10pt;">Every person with multiple sclerosis should have a comprehensive review of all aspects of their care at least once a year and that multidisciplinary teams - made up of multiple sclerosis nurses, GPs, psychologists, and therapists - should oversee the care they receive.<br /><br /></span></p> <p><span style="font-size: 10pt;">The guidance does not recommend the use of the cannabinoid drug Sativex or fampridine as they provide only a modest benefit at a significant cost to the NHS. Sativex costs &pound;50,000 per quality-adjusted life year (QALY), while fampridine costs in the region of &pound;160,000 per QALY. Both are well above NICE&rsquo;s threshold of &pound;30,000 per QALY.<br /><br /></span></p> <p><span style="font-size: 10pt;">Other key recommendations include offering people with multiple sclerosis an appropriate single point of contact to speak about their care, concerns and different treatment options, and encouraging people with multiple sclerosis to exercise. Supervised exercise programmes should be available for those who struggle with mobility and fatigue.</span></p></div> Costs to treat bleeding strokes increases 10 years later 2014-10-24T14:59:00Z 2014-10-24T14:59:00Z <div id="ImageMain25" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction25" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Costs to treat strokes caused by bleeding in the brain may increase significantly 10 years later, according to a study in the <em><a href="">American Heart Association</a></em> journal <em><a href="">Stroke</a>. </em>The Australian study is the first to include 10 years of follow-up data on stroke cost estimates</strong>.</span></p> </div><div id="Text125" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Generally, expenses associated with a stroke peak within the first year and decline over time. Previous estimates of lifetime costs in Australia were based on a five-year average and may have underestimated costs, specifically for haemorrhagic strokes.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Prevention of stroke should be a focus, since the costs of providing care to people who suffer stroke are unlikely to diminish,&rdquo; says Dominique Cadilhac, study senior author and an associate professor and head of the Translational Public Health: Stroke and Ageing Research Centre at Monash University in Victoria, Australia. &ldquo;Much could be gained if we could work to prevent the majority of strokes that are due to modifiable risk factors, such as high blood pressure or diabetes.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers interviewed 243 ischemic stroke patients and 43 intracerebral haemorrhage patients who had survived for 10 years or more. The patients had participated in an earlier Australian regional study that estimated five-year costs.</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers found that:</span></p> <ul> <li><span style="font-size: 10pt;">Average annual direct costs for ischaemic stroke remained stable between five to 10 years at about US$5,207.</span></li> <li><span style="font-size: 10pt;">Average annual direct costs for intracerebral haemorrhage stroke increased 31%, from US$5,807 at five years to US$7,607 at 10 years and the overall average lifetime costs per case for intracerebral haemorrhage stroke increased 25%, from US$43,786 to US$54,956.</span></li> <li><span style="font-size: 10pt;">Medication, aged-care facilities and informal care expenses explained the majority of costs at 10 years. Rehabilitation expenses decreased for ischemic stroke.</span></li> </ul> <p><span style="font-size: 10pt;">&ldquo;We did not know that the cost differentials would be so great between ischaemic stroke and interecerebral haemorrhage and that short-term estimates (six-12 months after a first stroke) used to approximate lifetime annual resource use after the first year would not be a good predictor of future costs,&rdquo; says Cadilhac, who is also the head of public health and epidemiology within the Stroke Division of the Florey Institute of Neuroscience and Mental Health and Data Custodian for the Australian Stroke Clinical Registry.</span><br /><br /></p> <p><span style="font-size: 10pt;">The Australian healthcare system is funded through public and private health insurance. However, the way health care is delivered and priced may influence cost differences between the two health systems. For example, if patients in America stay in the hospital longer or are offered different rehabilitation choices to what is available in Australia, estimates may be too low or high.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;We hope that our findings can be used to influence the need for more primary prevention and to also support assessment of the cost effectiveness of interventions to reduce disability from stroke,&rdquo; Cadilhac comments. &ldquo;In addition, ensuring that the best evidenced-based guideline treatment is provided in hospitals will assist in reducing disability associated with stroke and may, in turn, avoid unnecessary aged-care placements or an undue burden to caregivers.&rdquo;</span></p></div> Codman Neuro launches first disposable forceps with dual irrigation 2014-10-22T11:07:00Z 2014-10-22T11:07:00Z <div id="ImageMain26" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction26" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Codman Neuro has&nbsp;announced the launch of Spetzler Malis dual irrigating disposable non-stick bipolar forceps, the first disposable dual irrigating forceps for neurosurgery.

The median follow-up was 4.2 years. Both techniques were found to be equally good at preventing fatal and disabling strokes, but stented patients were slightly more likely to have minor strokes without long-term effects. The risk of any stroke in five years was 15.2% in the stenting group compared to 9.4% in the endarterectomy group, but the additional strokes were minor and had no impact on long-term quality of life.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;At the moment, stenting is not widely used in the UK due to historical uncertainty over its long-term effectiveness,&rdquo; says study leader Professor Martin Brown from the UCL Institute of Neurology. &ldquo;However, we have now shown that stenting is just as good as endarterectomy for preventing fatal and disabling strokes. We have also shown that the risk of stroke during the procedure is no higher for stenting than for endarterectomy in younger patients. The risks of each procedure are different and will vary depending on the patient, but stenting should be offered as an option to many more patients under the age of 70.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;One of the issues is that there are not many centres in this country that currently offer stenting as an option so the patient choice is not there.

Otherwise there is a vicious cycle where nobody at a centre has stenting experience so patients are only offered endarterectomy and staff cannot learn or observe the procedure. In other countries, stenting is more widespread and the safety of the procedure improves as staff gain experience.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Shamim Quadir, research communications manager at the Stroke Association, says: &ldquo;A transient ischaemic attack, also known as a mini-stroke, can be a warning sign that someone has carotid artery stenosis, and is at risk of having a major stroke.

The results of this study are published in the current issue of the <em><a href="" target="_blank">Journal of Endovascular Therapy</a>.</em> The researchers followed nine patients with significant (more than 80%) recurrent restenosis who underwent drug-eluting balloon angioplasty. In this procedure, a drug-eluting balloon is inflated for 60 seconds and delivers the drug paclitaxel, an inhibitor of the exuberant healing process after angioplasty that leads to restenosis.</span></p> <p><span style="font-size: 10pt;"><br />The angioplasty was successful in all 9 patients, with stenosis decreasing from 87% to 6%. These patients had clinical and ultrasound follow-up every three months during the first 24 months after the procedure, then were followed every six months. By approximately 36 months after the drug-eluting balloon angioplasty, only three patients were found to have recurrent in-stent restenosis at 18, 25, and 32 months, respectively, after the initial angioplasty, a far longer interval without restenosis than earlier treatments provided.</span></p> <p><span style="font-size: 10pt;"><br />These three patients underwent another drug-eluting balloon angioplasty procedure and did not experience restenosis at up to14 months after the second procedure. These results show the potential for the drug-eluting balloon treatment to improve outcomes for patients with early recurrent carotid in-stent restenosis.&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />In a related commentary article, the authors discuss lessons learned through this research. Their primary advice is not to wait, but to choose drug-eluting balloon angioplasty for treatment after the first failure of conventional endovascular intervention.

These new patents disclose unique design elements intended to enable both clot disengagement and capture and so facilitate the protected removal of hazardous clot from the brain. The CE-marked Embotrap revascularisation system incorporates these advanced features into its design.</span></p> <p><span style="font-size: 10pt;"><br />According to David Vale, chief technology officer for Neuravi, the company has established its extensive portfolio by a combination of external licensing and internal R&amp;D. &ldquo;This approach has given us a great combination of very early priority filings on the base technology as well as strong protection on the more advanced third generation features.

In the last decade, the question of where the disease begins has led researchers to a different part of the human anatomy. In 2003, the German neuropathologist Heiko Braak presented a theory suggesting that the disease begins in the gut and spreads to the brain. The idea has since, despite vocal critics, gained a lot of ground. Researchers at Lund University in Sweden now present the first direct evidence that the disease can actually migrate from the gut to the brain.&nbsp;</strong></span></p> </div><div id="Text136" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The so-called Braak&rsquo;s hypothesis proposes that the disease process begins in the digestive tract and in the brain&rsquo;s centre of smell. The theory is supported by the fact that symptoms associated with digestion and smell occur very early on in the disease.</span></p> <p><span style="font-size: 10pt;"><br />Researchers at Lund University have previously mapped the spread of Parkinson&rsquo;s in the brain. The disease progression is believed to be driven by a misfolded protein that clumps together and &ldquo;infects&rdquo; neighbouring cells. Professor Jia-Yi Li&rsquo;s research team has now been able to track this process further, from the gut to the brain in rat models. The experiment shows how the toxic protein, alpha-synuclein, is transported from one cell to another before ultimately reaching the brain&rsquo;s movement centre, giving rise to the characteristic movement disorders in Parkinson&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We have now been able to prove that the disease process actually can travel from the peripheral nervous system to the central nervous system, in this case from the wall of the gut to the brain. In the longer term, this may give us new therapeutic targets to try to slow or stop the disease at an earlier stage,&rdquo; says Professor Jia-Yi Li, research group leader for&nbsp;Neural Plasticity and Repair&nbsp;at Lund University.</span></p> <p><span style="font-size: 10pt;"><br />The research team will now carry out further studies in which the mechanisms behind the transport of the harmful protein will be examined in detail. The current study suggests that the protein is transferred during nerve cell communication. It is at this point of interaction that the researchers want to intervene in order to put a stop to the further spread of the disease.</span></p></div> Mechanism that repairs brain after stroke discovered 2014-10-13T11:35:00Z 2014-10-13T11:35:00Z <div id="ImageMain37" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction37" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institutet in Sweden. The findings have been published in the journal <a href="" target="_blank"><em>Science</em></a>.</strong></span></p> </div><div id="Text137" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain. Using genetic methods to map the fate of the cells, the scientists could demonstrate that astrocytes in this area formed immature nerve cells, which then developed into mature nerve cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;This is the first time that astrocytes have been shown to have the capacity to start a process that leads to the generation of new nerve cells after a stroke,&rdquo; says Zaal Kokaia, professor of Experimental&nbsp;Medical Research at Lund University.</span></p> <p><span style="font-size: 10pt;"><br />The scientists could also identify the signalling mechanism that regulates the conversion of the astrocytes to nerve cells. In a healthy brain, this signalling mechanism is active and inhibits the conversion, and, consequently, the astrocytes do not generate nerve cells. Following a stroke, the signalling mechanism is suppressed and astrocytes can start the process of generating new cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Interestingly, even when we blocked the signalling mechanism in mice not subjected to a stroke, the astrocytes formed new nerve cells,&rdquo; says Zaal Kokaia. &ldquo;This indicates that it is not only a stroke that can activate the latent process in astrocytes. Therefore, the mechanism is a potentially useful target for the production of new nerve cells, when replacing dead cells following other brain diseases or damage.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />The new nerve cells were found to form specialised contacts with other cells. It remains to be shown whether the nerve cells are functional and to what extent they contribute to the spontaneous recovery that is observed in a majority of experimental animals and patients after a stroke.</span></p> <p><span style="font-size: 10pt;"><br />A decade ago, Kokaia&rsquo;s and Lindvall&rsquo;s research group was the first to show that stroke leads to the formation of new nerve cells from the adult brain&rsquo;s own neural stem cells. The new findings further underscore that when the adult brain suffers a major blow such as a stroke, it makes a strong effort to repair itself using a variety of mechanisms.</span></p> <p><span style="font-size: 10pt;"><br />The major advancement with the new study is that it demonstrates for the first time that self-repair in the adult brain involves astrocytes entering a process by which they change their identity to nerve cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;One of the major tasks now is to explore whether astrocytes are also converted to neurons in the human brain following damage or disease. Interestingly, it is known that in the healthy human brain, new nerve cells are formed in the striatum. The new data raise the possibility that some of these nerve cells derive from local astrocytes. If the new mechanism also operates in the human brain and can be potentiated, this could become of clinical importance not only for stroke patients, but also for replacing neurons which have died, thus restoring function in patients with other disorders such as Parkinson&rsquo;s disease and Huntington&rsquo;s disease,&rdquo; says Olle Lindvall, senior professor of&nbsp;Neurology.</span></p></div> New Envoy catheters launched 2014-10-11T15:01:00Z 2014-10-11T15:01:00Z <div id="ImageMain38" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction38" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Codman Neuro has announced the Europe, Middle East and Africa launch of the EnvoyDA XB Distal Access Guiding Catheter and the 7F Envoy Guiding Catheter for neurovascular procedures.</strong></span></p> </div><div id="Text138" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;To support evolving treatment techniques and the need for versatile access solutions we have expanded our Envoy guide catheter line to provide interventional neuro-radiologists with choice.

In the trial, the efficacy of injecting support cells (astrocytes), produced by the company in a unique technology, into the spinal fluid of ALS model mice, was tested. This model is highly significant in predicting the treatment&rsquo;s activity in humans.</span></p> <p><span style="font-size: 10pt;"><br />The results of the trial showed an increased life expectancy in the mice treated, as well as a significant improvement of their motor (muscle) function, compared to the untreated mice. The efficacy of the treatment was also demonstrated in other indices indicating a delay in disease onset. Injections into the spinal fluid are standard procedure performed routinely in hospitals around the world. The company found that injections into the spinal fluid enable the even dispersion of cells throughout the central nervous system, thereby establishing the method of cell penetration in future treatment of patients.</span></p> <p><span style="font-size: 10pt;"><br />Professor Michel Revel, the company&rsquo;s chief scientist, notes, &ldquo;This is an important step in the company&rsquo;s progress towards the development of cellular therapy for ALS patients.

The ALS Finding a Cure Foundation is led by Peter N Foss, Lee Rizzuto and Denis Rizzuto. The foundation was created in April of 2014 and is a tribute to Denis&rsquo; wife, Christie Rizzuto, who was diagnosed with ALS five years ago at age 41. ALS ACT will enact a multi-pronged approach to expediting clinical trials in ALS. Efforts will include (1) developing neuroimaging tools as potential biomarkers for ALS progression, a key unmet need in trials; (2) development of therapeutic approaches to decrease production of misfolded proteins within motor neurons and reverse neuroinflammation, two major contributors to the disease process; (3) a challenge grant programme to overcome key roadblocks in the search for therapies; (4) support for phase IIA pilot clinical trials using biomarkers. Merit Cudkowicz, co-chair of the Northeast ALS Consortium (NEALS) and chief of neurology and the ALS Program at Massachusetts General Hospital (MGH), notes that these efforts will accelerate diagnosis, speed development of new treatments for people with ALS, and remove road blocks to finding a cure for ALS.</span></p> <p><span style="font-size: 10pt;"><br />In addition, ALS ACT will strengthen ongoing collaborative efforts in support of clinical trials, including NeuroBANK, a central repository for clinical research data in ALS, and the NEALS (Northeast ALS Consortium) Biorepository.

Finding these genes and understanding how they work will allow development of new therapeutic approaches. Under the leadership of Drs Robert Darnell and Hemali Phatnani together with their advisors, including Tom Maniatis and Marc Tessier-Lavigne , the NYGC will spearhead a cooperative and multidisciplinary effort to provide open-source &ldquo;big data&rdquo; to benefit the entire ALS research community.</span></p> <p><span style="font-size: 10pt;"><br />Investigators:&nbsp;Robert B Darnell; Hemali Phatnani; Tom Maniatis; Marc Tessier-Lavigne; Merit Cudkowicz; Robert J Brown, Jr; Virginia Lee; John Q Trojanowski, Alex Sherman; James Berry; Neil Shneider; David Goldstein; and Tom Jessell.</span></p> <p><span style="font-size: 10pt;"><strong><br />Neuro Collaborative</strong></span></p> <p><span style="font-size: 10pt;"><br />The Neuro Collaborative will combine the efforts of three world renowned California labs focused on ALS: Cedars-Sinai in Los Angeles, the University of California San Diego and the Gladstone Institutes, an affiliate of the University of California San Francisco, to develop and expedite therapeutic approaches for ALS. The collaborative, which now has funding to proceed with US$5 million in Ice Bucket Challenge funding from The ALS Association, will focus on the following: (1) development of antisense therapy for the C9orf72 gene, the most common genetic cause of ALS, in partnership with Biogen-Idec and ISIS Pharmaceuticals; (2) gene therapy to down regulate SOD1, the second-most common ALS gene; (3) establishment of a Stem Cell and Motor Neuron Core Facility to create clinical-grade induced pluripotent stem (iPS) cell lines, which will be openly shared with the ALS research community. iPS cells have emerged as a key research tool and potential source of therapeutic cells in ALS.( 4) Using a novel screening tool, identify new targets for drug development and in partnership with the industry these leads will be developed further with the potential of new treatment options in the clinic. The Golden West Chapter of The ALS Association has played a key role in the planning and development of this project.</span></p> <p><span style="font-size: 10pt;"><br />Investigators:&nbsp;Don Cleveland, UCSD; Steven Finkbeiner, the Finkbeiner lab at the Gladstone Institutes; Clive Svendsen, Cedar Sinai Medical Center; and collaborators, Martin Marsala, UCSD; and Brian Kaspar, Children&rsquo;s Hospital and Ohio State University.</span></p> <p><span style="font-size: 10pt;"><strong><br />Project MinE</strong></span></p> <p><span style="font-size: 10pt;"><br />Project MinE&nbsp;is a global collaboration with the goal to sequence the genomes of at least 15,000 people with ALS in an effort to discover new genes that affect ALS, either increasing the risk for the disease or protecting against it. The ALS Association&rsquo;s funding commitment of US$1 million will enable Project MinE to expand to the United States.&nbsp;</span><br /> <br /><span style="font-size: 10pt;"> <br />It has become clear that risk for ALS is likely influenced by variants in multiple genes, each of which is relatively rare.

Multiple studies have shown the value to a patient of attending a multidisciplinary clinic, including longer survival, increased quality of life, and improved access to potential therapies. One of the requirements in achieving certification through The ALS Association is for the institution to be actively involved in ALS-related research and to provide information to people living with the disease on research outside of their institution. Participation in clinical trials is imperative to the research process to find treatments for the disease. The Ice Bucket Challenge donations have enabled The Association to increase its annual grants to the centres from the presently budgeted US$12,500 to US$25,000 per centre, which was the funding level pre-2008, for the next three years.</span></p> <p><span style="font-size: 10pt;"><strong><br />Regulatory Guidance to Expedite Drug Development</strong></span></p> <p><span style="font-size: 10pt;"><br />Organisations involved in two other neurological diseases (Alzheimer&rsquo;s and Duchenne Muscular Dystrophy) have seen great benefits in working to develop guidance for companies to help them navigate the regulatory pathway for approval of effective therapies. The enactment of the patient-focused drug development elements of the Food and Drug Administration Safety and Innovation Act (FDASIA) presents a unique opportunity for The ALS Association to help expedite drug development by developing similar guidance for ALS. No such guidance exists today for ALS, which creates uncertainty and risk for what is already a difficult and costly process. By developing this guidance, The ALS Association will be able to build on and strengthen its engagement with the FDA, industry and people with ALS about drug development as a regulatory process, which will reduce obstacles that can slow and limit innovation and access to effective treatments.</span></p></div> IMRIS horseshoe headrest named Life Sciences Alley New Technology Showcase winner 2014-09-30T18:14:00Z 2014-09-30T18:14:00Z <div id="ImageMain44" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction44" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>IMRIS announced that its horseshoe headrest has been selected one of 10 New Technology Showcase Winners by Twin Cities-based Life Sciences Alley (LSA), the USA&rsquo;s largest regional medical industry association.

These patients may be babies whose skulls are still soft or older patients with weakened skull bones.</span></p> <p><span style="font-size: 10pt;"><br />The headrest also was specially designed for use with the new IMRIS InSitu wireless coil, a sterile, wireless, ultra-lightweight, and disposable imaging coil that eliminates the need to manage cables and heavy imaging coils typically draped and removed between intraoperative scans.</span></p> <p><span style="font-size: 10pt;"><br />Inside a VISIUS Surgical Theatre equipped with either high-field intraoperative MRI (iMRI) or 64-slice intraoperative Computed Tomography (iCT), surgeons have on-demand access to real-time diagnostic quality imaging during the procedure and from the operating room table as the scanner uniquely moves to the patient on ceiling-mounted rails. VISIUS iMRI provides neurosurgeons the ability to assess and decide to perform further resection for removing as much tumour as possible by clearly visualising tumour and healthy brain tissue which otherwise are hard to differentiate.</span></p></div> Collaboration established to advance diagnostic candidate to detect CTE in former NFL players 2014-09-29T17:54:00Z 2014-09-29T17:54:00Z <div id="ImageMain45" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction45" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Aethlon Medical and its diagnostic subsidiary, Exosome Sciences, have announced that a clinical collaboration with the Boston University CTE Center has been established to advance a blood-based diagnostic candidate that could identify Chronic Traumatic Encephalopathy (CTE) in living individuals.</strong></span></p> </div><div id="Text145" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">CTE is a progressive neurodegenerative disorder that has been found at autopsy in former National Football League (NFL) players. At present, CTE can only be diagnosed through post-mortem autopsy. The Boston University CTE Center has been a leading CTE research centre since the disease was first defined.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Aethlon Medical develops targeted therapeutic devices to address infectious disease, cancer and neurodegenerative disorders. Exosome Sciences develops exosome-based solutions to diagnose and monitor cancer and neurodegenerative disorders. Earlier this year, Aethlon disclosed that Exosome Sciences researchers had successfully isolated exosome-based biomarkers transporting tau protein across the blood-brain barrier and into the circulatory system. The hallmark of CTE is an excess of accumulation of tau in the brain.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />In the study, Exosome Sciences researchers are evaluating and defining exosome and exosomal tau populations in blood samples collected from participants enrolled in the DETECT (Diagnosing and evaluating traumatic encephalopathy using clinical tests) study, under the direction of Robert Stern, director of Clinical Research at the Boston University CTE Center.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The DETECT study is the first research project on CTE ever funded by the National Institutes of Health (NIH), with support from the National Institute of Neurologic Diseases and Stroke (NINDS), the National Institute on Aging (NIA), and the National Institute of Child Health and Human Development (NICHD). The ultimate goal of the study is to develop methods, including blood-based tests, that could diagnose CTE during life. The study has enrolled former NFL players (ages 40-69) and same-age &ldquo;control&rdquo; athletes who played non-contact sports.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our colleagues at the CTE Center are premier thought leaders in the CTE field and have been instrumental in changing how the NFL and other high-risk sports respond to head trauma,&rdquo; states Aethlon Medical chief executive officer, Jim Joyce, who also serves as executive chairman of Exosome Sciences. &ldquo;We are truly grateful for the opportunity to establish a blood-based test that could identify CTE in living individuals.&rdquo;</span></p></div> Medina Medical announces CE mark for its embolisation coil 2014-09-25T16:04:00Z 2014-09-25T16:04:00Z <div id="Introduction46" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Medina Medical has announced that it has received CE mark authorisation for its Embolization Framing Coil for commercial distribution in the European Union.</strong></span></p> </div><div id="Text146" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The Medina Embolization Framing Coil is used to treat brain aneurysms using minimally-invasive techniques, and is delivered like other embolization coils through a micro-catheter that has been threaded through blood vessels into the aneurysm.

The study results also argue the process can differentiate it from other forms of dementia while the sufferer is still alive. Until now, CTE diagnosis has only been possible by evaluating post-mortem brain tissue.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our data suggest that PET imaging using the [18F]-T807 tau tracer is an effective method of diagnosing or ruling out chronic traumatic encephalopathy in a living brain,&rdquo; says Samuel Gandy, director of the Center for Cognitive Health and NFL Neurological Care at the Icahn School of Medicine at Mount Sinai, USA. &ldquo;Estimates of the prevalence of CTE have varied wildly, with the most recent figure coming from the National Football League who predicts that one in three NFL players will suffer significant brain damage. We can now begin to test this while the players are still alive. Moreover, we are now equipped to tell prospective athletes of all ages some real data on the risks that accompany sports involving repeated traumatic brain injuries.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Signs of CTE were originally spotted in boxers and retired National Football League (NFL) players. Before their deaths, many of these athletes struggled with symptoms like memory loss, depression, and violent outbursts, and in some cases they became suicidal. The NFL is currently helping to launch large-scale studies of the condition. More recently, the brains of ice hockey players and battlefield veterans exposed to repeated bomb blasts have revealed evidence of CTE.</span></p> <p><span style="font-size: 10pt;"><br />In recent years, scientists have developed radiotracers like [18F]-T807 that attach to protein aggregates and emit high-energy particles called positrons that are registered on a PET scanner. The [18F]-T807 tau tracer selectively binds only to tangles of tau in the brain and not to amyloid proteins associated with Alzheimer&rsquo;s disease, making it superior to other proposed tau tracers to date in terms of CTE detection, according to the study authors.</span></p> <p><span style="font-size: 10pt;"><br />The Mount Sinai case study included the evaluations of two living patients, a retired NFL football player with a history of multiple concussions and a patient with a single, severe traumatic brain injury (TBI). Both patients presented with cognitive decline and suspected Alzheimer&rsquo;s disease. Both were evaluated by a combination of molecular imaging techniques to pinpoint specific brain disease and damage.</span></p> <p><span style="font-size: 10pt;"><br />Brain injury, whether as a result of repeated head trauma or a single, traumatic brain event, may jumpstart a process whereby tau protein, which functions in a healthy brain to help stabilise a nerve cell&rsquo;s protein skeleton, breaks off the skeleton and begins to build up inside nerve cells. The theory is that tangles of tau protein accumulate and cause nerve cell damage in the CTE brain.</span></p> <p><span style="font-size: 10pt;"><br />While various dementias like CTE and Alzheimer&rsquo;s disease share many symptoms, the nature and distribution of brain degeneration in chronic traumatic encephalopathy is distinctive from Alzheimer&rsquo;s disease. CTE is characterised by prominent formation inside nerve cells of structures called tangles, a process called a tauopathy. The dementia of CTE occurs in midlife after a latency period of years or decades after exposure to repetitive head trauma.</span></p> <p><span style="font-size: 10pt;"><br />In this study, led by Gandy, both patients underwent neurologic and neuropsychological assessments by a team of traumatic brain injury and Alzheimer&rsquo;s disease experts. Following this comprehensive evaluation, the experts disagreed as to whether Alzheimer&rsquo;s disease was present in this retired NFL player.</span></p> <p><span style="font-size: 10pt;"><br />Both patients underwent PET imaging with florbetapir, another chemical that is FDA-approved to detect the brain amyloid plaques of Alzheimer&rsquo;s disease during life. In the case of the retired NFL player, who suspected he had Alzheimer&rsquo;s disease and presented to the team at Mount Sinai in hope to participate in a clinical study for Alzheimer&rsquo;s disease, the florbetapir PET scan was negative for cerebral amyloidosis, thereby excluding Alzheimer&rsquo;s disease and the possibility of his engaging in a treatment protocol for his suspected, incorrect Alzheimer&rsquo;s disease diagnosis. He also underwent [18F]-T807 PET imaging that revealed signs of aggregated tau in some temporal areas of his brain.</span></p> <p><span style="font-size: 10pt;"><br />The current study is the first where one technology was able to show both the abnormal accumulation of tau protein in a person that experienced several concussions in the distant past, while at the same time demonstrating that the patient did not have the protein signature seen with Alzheimer&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Although we are just now understanding the clinical impact of PET, our use of tauopathy PET imaging to evaluate the progressive alterations in brain proteins for CTE patients already offers us a powerful new tool for evaluation,&rdquo; says Ken Marek, president and senior scientist at Molecular Neuroimaging (MNI) in New Haven, USA, where the [18F]-T807 imaging was performed. &ldquo;In particular, we can directly measure the accumulation of&nbsp;tau protein&nbsp;we believe associated with the devastating symptoms experienced by patients and their families and evaluate the disease during life in ways that were previously only available to the pathologist&rsquo;s microscope.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />A tauopathy imaging programme at Mount Sinai Hospital is expected to commence in early October 2014.</span></p> <p><span style="font-size: 10pt;">Researchers from the University of Virginia also contributed to the study.</span></p></div> EBS expands commercialisation of Next Wave non-invasive electrical brain stimulation device 2014-09-24T11:17:00Z 2014-09-24T11:17:00Z <div id="Introduction48" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>EBS Technologies has&nbsp;announced that it has opened its first ophthalmologic clinical site in Germany that is offering the use of the EBS&nbsp;Next Wave<em>&nbsp;</em>brain stimulation device designed to expand the visual field of patients with impaired vision caused by glaucoma, stroke and other neurological diseases.</strong></span></p> </div><div id="Text148" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Last week, EBS announced that a clinical study (&ldquo;Brain functional connectivity network breakdown and restoration in blindness&rdquo;) published in the journal&nbsp;<em>Neurology</em>&nbsp;validates non-invasive brain stimulation for restoring partial vision to an impaired eye; the company&rsquo;s&nbsp;Next Wave&nbsp;system is a non-invasive brain stimulation device that is designed to expand the visual field of patients with impaired vision caused by glaucoma, stroke or other neurological disorders.

If replicated on a larger scale, this could represent meaningful improvement in quality of life, and lifespan, compared to untreated patients. In our phase II dose escalation trial, we successfully reached the maximal dose planned, which consisted of&nbsp; 20 lumbar and 20 cervical injections of 400,000 cells each, more than ten times the number of stem cells delivered in the highest dose cohort of the phase I trial.&rdquo;&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The progress in this trial is truly groundbreaking,&rdquo; says Glass, who is director of the Emory ALS Center at Emory University, the first site in the trial. &ldquo;It has provided data on the safety of multiple injections and multiple transplantation surgeries in ALS patients, as well as the long- term survival of the transplanted cells in the human spinal cord.

While calling for further research in key areas, Clement Hamani of Toronto Western Hospital and co-authors emphasise that patients with OCD symptoms that do not respond to other treatments should continue to have access to deep brain stimulation.</span></p> <p><span style="font-size: 10pt;"><br />Hamani led a multispecialty expert group in performing a systematic review of research on the effectiveness of deep brain stimulation for OCD. Deep brain stimulation&mdash;placement of electrodes in specific areas of the brain, followed by electrical stimulation of those areas&mdash;has become an important treatment for patients with Parkinson&rsquo;s disease and other movement disorders.</span></p> <p><span style="font-size: 10pt;"><br />Although many patients with OCD respond well to medications and/or psychotherapy, 40 to 60% continue to experience symptoms despite treatment. Over the past decade, a growing number of reports have suggested that deep brain stimulation may be an effective alternative in these &ldquo;medically refractory&rdquo; cases.</span></p> <p><span style="font-size: 10pt;"><br />Hamani and colleagues were tasked with analysing the supporting evidence and developing an initial clinical practice guideline for the use of deep brain stimulation for patients with OCD. The review and guideline development process was sponsored by the American Society of Stereotactic and Functional Neurosurgery and the CNS. Out of more than 350 papers, the reviewers identified seven high-quality studies evaluating deep brain stimulation for OCD.</span></p> <p><span style="font-size: 10pt;"><br />Based on that evidence, they conclude that bilateral stimulation (on both sides of the brain) of two brain &ldquo;targets&rdquo;&mdash;areas called the subthalamic nucleus and the nucleus accumbens&mdash;can be regarded as effective treatments for OCD. In controlled clinical trials, both techniques improved OCD symptoms by around 30% on a standard rating scale.</span></p> <p><span style="font-size: 10pt;"><br />That evidence forms the basis for a clinical guideline stating that bilateral deep brain stimulation is a &ldquo;reasonable therapeutic option&rdquo; for patients with severe OCD that does not respond to other treatments. The guideline also notes that there is &ldquo;insufficient evidence&rdquo; supporting the use of any type of unilateral deep brain stimulation target (one side of the brain) for OCD.</span></p> <p><span style="font-size: 10pt;"><br />The review highlights the difficulties of studying the effectiveness of deep brain stimulation for OCD&mdash;because most patients respond to medical treatment, studies of this highly specialised treatment typically include only small numbers of patients. Hamani and co-authors identify some priorities for future research: particularly to identify the most effective brain targets and the subgroups of patients most likely to benefit.</span></p> <p><span style="font-size: 10pt;"><br />Despite the limited evidence base, deep brain stimulation therapy for OCD has been approved by the Food and Drug Administration under a humanitarian device exemption. Hamani and co-authors note that various safeguards are in place to ensure appropriate use, and prevent overuse, of deep brain stimulation for OCD.</span></p> <p><span style="font-size: 10pt;"><br />While research continues, they believe that functional neurosurgeons should continue to work with other specialists to ensure that patients with severe, medically refractory OCD continue to have access to potentially beneficial deep brain stimulation therapy.</span></p></div> ATL1102 phase II trial results published in Neurology 2014-09-23T17:00:00Z 2014-09-23T17:00:00Z <div id="Introduction52" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Antisense Therapeutics has reported the publication of previously generated phase IIa clinical trial data on ATL1102 in the medical journal <a href="" target="_blank"><em>Neurology</em></a>.</strong></span></p> </div><div id="Text152" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The article titled &ldquo;CD49d antisense drug ATL1102 reduces disease activity in patients with relapsing-remitting MS&rdquo;, is currently available online and will be included in the print edition Volume 83, November 11, 2014.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The article highlights the successful outcomes of the Phase IIa clinical trial of ATL1102 in Multiple Sclerosis (MS) patients where in the randomised, double-blind, placebo-controlled study in 77 patients with relapsing-remitting multiple sclerosis (RRMS), ATL1102 met its primary end point after only two months of dosing, showing a significant reduction, by 54.4% (p=0.01) in the cumulative number of new active brain lesions in patients taking ATL1102 compared to placebo.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The efficacy outcomes from this study were viewed to be as good as, or superior to, those achieved with MS drug Tysabri at a similar stage in its clinical development. Tysabri (natalizumab) is a monoclonal antibody drug targeting the VLA-4 receptor (same target as ATL1102). In 2013, Tysabri generated sales in excess of US$1.6 billion.

The potential therapy also decreased the emergence of new brain damage seen by magnetic resonance imaging (MRI) by more than 90%.</span></p> <p><span style="font-size: 10pt;"><br />In addition, safety results suggest a favourable risk-benefit profile. More than 98% of patients remained on the drug regimen&mdash;an important metric as existing drugs for multiple sclerosis are often difficult for patients to tolerate.</span></p> <p><span style="font-size: 10pt;">RPC1063 was first discovered by a &ldquo;hit&rdquo; from a National Institutes of Health molecular library during research at Scripps Florida&rsquo;s Molecular Screening Center.

We expect many other programmes that Scripps Florida has been involved in will have similar potential to improve human health.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />The new RPC1063 findings were presented recently at the MS Boston 2014 meeting.</span></p> <p><span style="font-size: 10pt;"><br />Receptos, a San Diego biopharmaceutical company that licensed the technology from The Scripps Research Institute, is developing RPC1063 for approval by the US Food and Drug Administration.

Any imbalance in this pathway (too much or too little activity) leads to disease &mdash; the overgrowth of cells in cancer is one example of overactivation of this pathway.</span></p> <p><span style="font-size: 10pt;"><br />While much research on Wnt has focused on diseases involved in overactive Wnt signalling, Bu&rsquo;s team is one of the first to demonstrate the link between suppressed Wnt signalling and Alzheimer&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our finding makes sense, because researchers have long known that patients with cancer are at reduced risk of developing Alzheimer&rsquo;s disease, and vice versa,&rdquo; Bu says. &ldquo;What was not known is that Wnt signalling was involved in that dichotomy.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Using a new mouse model, the investigators discovered the key defect that leads to suppressed Wnt signalling in Alzheimer&rsquo;s. They found that the low-density lipoprotein receptor-related protein 6 (LRP6) is deficient, and that LRP6 regulates both production of amyloid beta, the protein that builds up in the brains of Alzheimer&rsquo;s disease patients, and communication between neurons. That means lower than normal levels of LRP6 leads to a toxic buildup of amyloid and impairs the ability of neurons to talk to each other.</span></p> <p><span style="font-size: 10pt;"><br />Mice without LRP6 had impaired Wnt signalling, cognitive impairment, neuroinflammation and excess amyloid.</span></p> <p><span style="font-size: 10pt;"><br />The researchers validated their findings by examining post-mortem brain tissue from Alzheimer&rsquo;s patients &mdash; they found that LRP6 levels were deficient and Wnt signalling was severely compromised in the human brain they examined.</span></p> <p><span style="font-size: 10pt;"><br />The good news is that specific inhibitors of this pathway are already being tested for cancer treatment. &ldquo;Of course, we do not want to inhibit Wnt in people with Alzheimer&rsquo;s or at risk for the disease, but it may be possible to use the science invested in inhibiting Wnt to figure out how to boost activity in the pathway,&rdquo; Bu says.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Identifying small molecule compounds to restore LRP6 and the Wnt pathway, without inducing side effects, may help prevent or treat Alzheimer&rsquo;s disease,&rdquo; he says. &ldquo;This is a really exciting new strategy &mdash; a new and fresh approach.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Researchers from the University of Kentucky, Xiamen University in China, the University of Oklahoma and the Korea Brain Research Institute participated in the study.</span></p></div> CE mark for Vercise deep brain stimulation system for patients with tremor 2014-09-18T16:09:00Z 2014-09-18T16:09:00Z <div id="ImageMain56" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction56" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Boston Scientific has received CE mark approval for the Vercise deep brain stimulation system for the treatment of tremor, including the most common form of this movement disorder known as essential tremor.

GeNeuro tested its monoclonal antibody GNbAC1 in 10 multiple sclerosis patients, nine of which had primary or secondary progressive disease. GNbAC1 targets the MSRV-Env protein expressed by genes of endogenous retroviral origin, which GeNeuro believe plays a critical role in the pathogenesis of multiple sclerosis.</strong></span></p> </div><div id="Text166" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The long-term safety profile of GNbAC1 was confirmed, with excellent tolerability among patients following repeat administration, verifying results of the earlier phase I study. With respect to clinical endpoints, the average Expanded Disability Status Score (EDSS), which measures disease progression, remained stable over one year. MRI analysis revealed that the brain images also remained stable and biomarkers associated with the target showed a consistent decline. These results confirm the safety and tolerability of GNbAC1 and support a positive pharmacodynamic response to the treatment. The positive results of this clinical study represent the successful first step in GeNeuro&rsquo;s phase II programme. A proof-of-concept clinical study to test the efficacy of GNbAC1 in multiple sclerosis will follow in 2015.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Francois Curtin, chief executive officer of GeNeuro states: &ldquo;We are very excited by the potential that GNbAC1 offers as a new avenue to treat multiple sclerosis patients. In addition to confirmation of long-term safety of the monoclonal antibody in patients, we have seen that the cohort of progressive multiple sclerosis patients was stable over one year from both clinical and MRI standpoints. Moreover, there is a clear decrease in the associated biomarkers supporting a positive pharmacodynamic response. This reinforces our conviction that GNbAC1 can completely transform the multiple sclerosis therapeutic landscape.&rdquo; Curtin adds: &ldquo;Preliminary results of this study presented at the American Academy of Neurology earlier this year generated a high level of enthusiasm among clinicians as they see that this treatment could bring new hope to patients as a safe therapy addressing a causal factor of the disease, breaking with the immunosuppressive logic of existing treatments.&rdquo;</span></p></div> National charity unveils big new ambitions for children with brain injury 2014-09-01T17:43:00Z 2014-09-01T17:43:00Z <div id="Introduction67" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The UK&rsquo;s leading charity for children with brain injury has launched a new three-year strategy, outlining ambitious plans to reach thousands more children and families across the UK.</strong></span></p> </div><div id="Text167" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">By 2017, The Children&rsquo;s Trust aims to be reaching 2,500 children living with brain injury every year through a major expansion of its community services.

The technology utilises advanced signal processing methods and classification algorithms that quantify and characterise features of brain electrical activity associated with traumatic brain injury.</span></p> <p><span style="font-size: 10pt;"><br />In this prospective validation study, ten minutes of brain electrical activity were recorded in 46 adult patients with traumatic haematomas with measureable blood (CT scan positive, &ge;1cc of blood) and 278 head-injured control patients (CT scan negative). The mild presentation of the entire study population is reflected by 97% (313/324) of the patients in the study having a normal Glasgow Coma Scale score of 15 (on a scale of 3&ndash;15), with a mean value of 14.7 for the population with haematomas, and 14.9 for the control group. The volume of blood and distance from recording electrodes were measured by blinded independent experts. A previously derived classification algorithm developed by BrainScope (the &ldquo;TBI-index&rdquo;) was used to identify the probability of a traumatic CT positive lesion in this clinically important independent population.</span></p> <p><span style="font-size: 10pt;"><br />The study reported a sensitivity of 96% to haematomas, which was independent of type of haematoma, blood volume, or distance of the bleed from the recording electrodes on the forehead. Because of the life-threatening risk associated with undetected haematomas, specificity was permitted to be lower (44%) in exchange for extremely high sensitivity. In this study population (n=324), all subjects had been referred for CT scanning by standard clinical practice, of whom 278 were found to be CT negative. These results replicate previously peer-reviewed published findings (Hanley and colleagues, <em>Journal of Neurotrauma</em>, 2013) using the technology in traumatic haematomas, and again importantly demonstrated that the distance and volume restrictions noted with other commercially available methods for detecting traumatic intracranial haematomas were not limitations of BrainScope&rsquo;s technology. These results lend further strong support to the potential enhanced clinical utility of the BrainScope TBI-Index as an important adjunct to acute assessment and triage of clinically important (potentially life-threatening) brain injuries.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Often patients such as those in this study present with very mild symptoms of traumatic brain injury and therefore pose difficult triage decisions upon clinical evaluation. It is not always clear whether the patient might have a clinically important traumatic brain injury (blood in the brain) requiring further clinical evaluation. The ability to determine the likelihood of presence of such injuries non-invasively and without radiation could result in a paradigm shift in the way emergency medicine for TBI is currently practiced,&rdquo; says Michael Singer, president and chief executive officer of BrainScope. &ldquo;This peer-reviewed publication, which independently validated the prior 2013 publication, provides further compelling evidence about the potential for our technology to help assess the existence of brain injuries shortly after injury. Whether in the military or civilian hospital emergency departments, there is a true need for an objective, adjunctive assessment tool for TBI beyond what currently exists. We are highly encouraged by the independent prospective replication of these results.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />BrainScope devices under development for assessment of traumatically-induced head injury and concussion are for investigational use only.</span></p></div> NICE approves Tecfidera (dimethyl fumarate) 2014-08-29T17:11:00Z 2014-08-29T17:11:00Z <div id="ImageMain69" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction69" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Thousands of adults in England and Wales living with the most common type of multiple sclerosis may benefit from a new oral treatment, Tecfidera (dimethyl fumarate), as the National Institute for Health and Care Excellence (NICE) issues the Technology Appraisal Guidance (TAG).</strong> </span>&nbsp;</p> </div><div id="Text169" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">NICE has approved Tecfidera as an option for treating adults with active relapsing remitting multiple sclerosis &ndash; normally defined as two clinically significant relapses in the previous two years &ndash; only if, they do not have highly active or rapidly evolving severe relapsing remitting multiple sclerosis and the manufacturer provides Tecfidera with the discount agreed in the patient access scheme.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The NHS will have a three month period to implement the guidance.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Tecfidera is a new oral treatment, licensed for adult patients with relapsing remitting multiple sclerosis.

They add that high-resolution neuroimaging and invasive electrographic studies could be beneficial.</span></strong></p> </div><div id="Text171" style="clear:both; text-align:left"><p>According to the study&rsquo;s lead author, Dario J Englot there is differences in epilepsy type and pathological substrates between children and adults. He explains that because young children have greater neural plasticity and potential for neurological recovery than adults, extremely aggressive resection such as hemispherectomy would be devastating in an adult, adding that critical functions such as language and motor abilities are more likely to improve post-operatively in a young child, due to reorganisation of eloquent cortex.<br /><br />However, they say that, although resection is a tried and tested treatment method, some patients continue to experience seizures post-surgery.<br /><br />Englot and colleagues performed a retrospective cohort study of children and adolescents who underwent focal respective surgery to determine the reasons for surgical failure. They also performed quantitative and qualitative analyses of factors associated with persistent post-operative seizures. The results were published in the <a href="" target="_blank"><em>Journal of Neurosurgery: Pediatrics</em></a>.<br /><br />They reviewed data from 110 patients (115 resections) and found that 76% of patients were free from disabling seizures (Engel Class I outcome) at a mean follow-up of 3.1 years.<br /><br />They say that freedom from seizures was predicted by temporal lobe surgery compared with extratemporal resection, tumour or mesial temporal sclerosis compared with cortical dysplasia or other pathologies and by a lower preoperative seizure frequency.<br /><br />From their findings, it was demonstrated that factors associated with persistent seizures (Engel Class II&ndash;IV outcome) were residual epileptogenic tissue adjacent to the resection cavity (40%), an additional epileptogenic zone distant from the resection cavity (32%), and the presence of a hemispheric epilepsy syndrome (28%).<br /><br />&ldquo;While seizure outcomes in paediatric epilepsy surgery may be improved by the use high-resolution neuroimaging and invasive electrographic studies, a more aggressive resection should be considered in certain patients&rdquo;, Englot <em>et al</em> state.<br /><br />They conclude that aggressive resection should extend to hemispherectomy, if a hemispheric epilepsy syndrome is suspected. Englot told <em>NeuroNews</em>: &ldquo;While it is critical to carefully tailor resections to avoid neurological deficits, it is also true that seizure-freedom is the strongest predictor of quality of life. In our view, an aggressive resection involves maximal removal of tissue that is involved in the epileptogenic zone, while preserving eloquent brain regions to the greatest extent possible. For example, in a child with epilepsy caused by a benign brain tumour (e.g. ganglioglioma), a limited resection might involve lesionectomy alone, while an aggressive resection may include intraoperative interictal electrocorticography to delineate epileptogenic peri-tumoral cortex which should also be removed.&rdquo;<br /><br />They add that the patient should receive counselling on treatment expectations as reoperation may be required in some cases.</p> </div> Highest level evidence indicates better outcomes when using iMRI for brain tumour surgery 2014-08-26T16:37:00Z 2014-08-26T16:37:00Z <div id="ImageMain72" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction72" style="clear:both;"> <p><strong><span style="font-size: 11pt;">In a recently published article in the journal <a href="" target="_blank"><em>Neurosurgery</em></a> the use of VISIUS intraoperative MRI (iMRI) in brain tumour surgery has been proven to result in complete tumour removal in more patients with glioma tumours.&nbsp;</span></strong></p> </div><div id="Text172" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Led by Jin-song Wu, the neurosurgical team at Huashan Hospital at Fudan University in Shanghai, China, conducted the study.</span><br /><br /><span style="font-size: 10pt;">The prospective, parallel, randomised, triple-blind controlled trial design provides the most objective data and therefore highest level evidence to date of the value of iMRI in treating both low and high-grade gliomas.

Other published studies on high-field iMRI have been mainly retrospective.</span><br /><br /><span style="font-size: 10pt;">&ldquo;iMRI is a practical and valuable asset to increasing the extent of resection for cerebral gliomas, with a specific significant influence for low grade gliomas,&rdquo; Wu says. &ldquo;With trends to statistical significance, these early results are the highest level of iMRI evidence for glioma surgery now available. This leads to more improved overall survivability and quality of life than using conventional neuronavigation.&rdquo;</span><br /><br /><span style="font-size: 10pt;">The low-grade glioma (LGG) subgroup patients who were treated in a VISIUS Surgical Theatre using iMRI had a statistically significant complete resection rate of 82% compared to 43% for the control group of conventional surgery patients.

An even higher percentage of respondents, 81%, would want to identify an incurable neurological disorder if it affected somebody close to them, with more women (84%) wanting to know than men (76%). The &ldquo;Value of Knowing&rdquo; global survey of 10,000 adults across 10 countries explored perspectives on incurable neurological disorders including Alzheimer&rsquo;s and Parkinson&rsquo;s.</strong></span></p> </div><div id="Text177" style="clear:both; text-align:left"><p><span style="font-size: 10pt;"><strong>Prepared to pay for diagnosis</strong></span></p> <p><span style="font-size: 10pt;"><br />While the overwhelming consensus (94%) is that the government or health insurance providers should cover diagnosis, approximately half (51%) of respondents indicated that they would even be prepared to pay for a diagnosis themselves. This sentiment was particularly prevalent in India and China, where 71% and 83% respectively, said they would be prepared to pay. This was echoed by almost one half of those questioned in Russia and around one-third of respondents in UK, USA and Japan.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;What these statistics tell us is just how strongly people feel about tackling neurological disorders like dementia,&rdquo; says Marc Wortmann, executive director of Alzheimer&rsquo;s disease International. &ldquo;Worldwide, nearly 44 million people have dementia and this number is expected to nearly double in 20 years as the world&rsquo;s population ages. Although there is no cure yet, a timely diagnosis is useful for people with dementia to get access to current treatment, services and support, both medical and non-medical. Governments and healthcare systems need to ensure ready access to the diagnostic tools already available to accurately diagnose disorders such as Alzheimer&rsquo;s and Parkinson&rsquo;s, so that people can manage the symptoms as early as possible.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />When people surveyed were asked why they would want to know, the most common answer (71%) was to start treatment that could help manage the symptoms of the disease. Other reasons included the opportunity to change lifestyle to potentially slow the impact of the illness (66%), and the ability to make informed decisions (62%). Those who would not want to know cited undue worry and the futility of knowing about their disorder without being able to control it.</span></p> <p><span style="font-size: 10pt;"><br />Ben Newton, director of PET Neurology for GE Healthcare, comments, &ldquo;It is understandable that dementia is a frightening topic for people. That said, although there are currently no cures for many neurological disorders, there are symptom-modifying therapies and approaches available if detected early enough. It is interesting to note that the majority of respondents with more experience of a neurological disorder via a loved one for example, said that they would want to know, in spite of there being no cure.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />Recognising the symptoms</strong></span></p> <p><span style="font-size: 10pt;"><br />The research also probed respondents&rsquo; recognition of the possible signs and symptoms of dementia. While a majority recognised memory loss (70%) and disorientation (61%) as signs of dementia, less than half of those surveyed were able to identify other very common symptoms, including language problems, personality, mood and behaviour changes, and loss of initiative.</span></p> <p><span style="font-size: 10pt;"><br />Newton adds, &ldquo;Understanding and knowing all the symptoms of a neurological disorder are critical to helping loved ones who may be showing early signs. Acting early on any concerns may mean patients have access to earlier diagnosis and intervention, which could help to manage and delay the impact of a disorder.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />For decades, GE Healthcare has produced diagnostics scanners, imaging agents and software to help physicians see more clearly inside the brain and aid better patient management. Between 2010 and 2020, GE Healthcare plans to invest over US$500 million in research into neurological disorders. The investment crosses all lines of GE Healthcare and focuses on developing new neurology diagnostic solutions, educating consumers, and expanding research already in progress. Target areas include diagnosing post-traumatic stress disorder, Alzheimer&rsquo;s disease, Parkinson&rsquo;s disease, multiple sclerosis, stroke, concussion and traumatic brain injury.</span></p></div> Utah team invents way to image brains of mice using small needle 2014-08-20T10:38:00Z 2014-08-20T10:38:00Z <div id="Introduction78" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A University of Utah team discovered a method for turning a small, US$40 needle into a 3D microscope capable of taking images up to 70 times smaller than the width of a human hair. This new method not only produces high-quality images comparable to expensive microscopes, but may be implanted into the brains of living mice for imaging at the cellular level.</strong></span></p> </div><div id="Text178" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The study appears in the 18 August issue of the journal&nbsp;<a href="" target="_blank"><em>Applied Physics Letters</em></a>.</span></p> <p><span style="font-size: 10pt;"><br />Designed by Rajesh Menon, an associate professor of electrical and computer engineering, and graduate student Ganghun Kim, the microscope technique works when an LED light is illuminated and guided through a fiberoptic needle or cannula. Returned pictures are reconstructed into 3D images using algorithms developed by Menon and Kim.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Unlike miniature microscopes, our approach does not use optics,&rdquo; Menon says. &ldquo;It&rsquo;s primarily computational.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />He says this approach will allow researchers not only to take images far smaller than those taken by current miniature microscopes, but do it for a fraction of the cost.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We can get approximately 1-micron-resolution images that only US$250,000 and higher microscopes are capable of generating,&rdquo; Menon says. &ldquo;Miniature microscopes are limited to the few tens of microns.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Menon hopes to extend the technology in the future so it can see details down to submicron resolutions, compared with the current 1.4 microns. (A micron is a millionth of a metre. A human hair is about 100 microns wide.)</span></p> <p><span style="font-size: 10pt;"><br />The microscope was originally designed for the lab of Nobel Prize-winning U human genetics professor, Mario R Capecchi, whose team will use it to observe the brains of living mice to gain insight into how certain proteins in the brain react to various stimuli.

The&nbsp;study&nbsp;was published in the July issue of the&nbsp;<em><a href="" target="_blank">Journal of Cerebral Blood Flow &amp; Metabolism</a>.</em></strong></span></p> </div><div id="Text179" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This is an important breakthrough in getting drugs delivered to specific parts of the brain precisely, non-invasively, and safely, and may help in the treatment of central nervous system diseases like Parkinson&rsquo;s and Alzheimer&rsquo;s,&rdquo; says Konofagou, whose National Institutes of Health Research Project Grant (R01) funding was just renewed for another four years for an additional US$2.22 million. The award is for research to determine the role of the microbubble in controlling both the efficacy and safety of drug safety through the BBB with a specific application for treating Parkinson&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />Most small&mdash;and all large&mdash;molecule drugs do not currently penetrate the blood-brain barrier that sits between the vascular bed and the brain tissue. &ldquo;As a result,&rdquo; Konofagou explains, &ldquo;all central nervous system diseases remain undertreated at best. For example, we know that Parkinson&rsquo;s disease would benefit by delivery of therapeutic molecules to the neurons so as to impede their slow death. But because of the virtually impermeable barrier, these drugs can only reach the brain through direct injection and that requires anaesthesia and drilling the skull while also increasing the risk of infection and limiting the number of sites of injection. And transcranial injections rarely work&mdash;only about one in ten is successful.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Focused ultrasound in conjunction with microbubbles&mdash;gas-filled bubbles coated by protein or lipid shells&mdash;continues to be the only technique that can permeate the BBB safely and non-invasively. When microbubbles are hit by an ultrasound beam, they start oscillating and, depending on the magnitude of the pressure, continue oscillating or collapse. While researchers have found that focused ultrasound in combination with microbubble cavitation can be successfully used in the delivery of therapeutic drugs across the BBB, almost all earlier studies have been limited to one specific-sized agent that is commercially available and widely used clinically as ultrasound contrast agents. Konofagou and her team were convinced there was a way to induce a size-controllable BBB opening, enabling a more effective method to improve localised brain drug delivery.</span></p> <p><span style="font-size: 10pt;"><br />Konofagou targeted the hippocampus, the memory centre of the brain, and administered different-sized sugar molecules (Dextran). She found that higher acoustic pressures led to larger molecules accumulating into the hippocampus as confirmed by fluorescence imaging. This demonstrated that the pressure of the ultrasound beam can be adjusted depending on the size of the drug that needs to be delivered to the brain: all molecules of variant sizes were able to penetrate the opened barrier but at distinct pressures, ie., small molecules at lower pressures and larger molecules at higher pressures.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Through this study, we have been able to show, for the first time, that we can control the BBB opening size through the use of acoustic pressure,&rdquo; says Konofagou. &ldquo;We have also learned much more about the physical mechanisms associated with the trans-BBB delivery of different-sized agents, and understanding the BBB mechanisms will help us to develop agent size-specific focused ultrasound treatment protocols.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Konofagou and her&nbsp;Ultrasound Elasticity Imaging Laboratory&nbsp;team plan to continue to work on the treatment of Alzheimer&rsquo;s and Parkinson&rsquo;s in a range of models, and hope to test their technique in clinical trials within the next five years.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;It is frightening to think that in the 21<sup>st</sup>&nbsp;century we still have no idea how to treat most brain diseases,&rdquo; Konofagou adds. &ldquo;But we are really excited because we now have a tool that could potentially change the current dire predictions that come with a neurological disorder diagnosis.&rdquo;</span></p></div> electroCore appoints Piper Jaffray to deal with growing interest from pharma 2014-08-19T10:29:00Z 2014-08-19T10:29:00Z <div id="ImageMain80" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction80" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>electroCore has appointed Piper Jaffray to assist in discussions with pharma companies who are interested in partnering with it on the commercialisation of its breakthrough non-invasive vagus nerve (nVNS) stimulation therapy.</strong></span></p> </div><div id="Text180" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;The interest from pharma, medical devices and even technology companies has grown considerably over the last six months,&rdquo; comments chief executive officer and founder JP Errico. &ldquo;We wanted to explore all the opportunities for our future, from partnership to remaining independent. We therefore had discussions with several banks to help us with this process and chose Piper Jaffray. We are under no pressure to do a deal as we are fully funded until 2016.

The study further suggests that patients who remained on therapy for longer periods of time, may enjoy progressively larger decreases in headache days over the period they are on therapy.</span></p> <p><span style="font-size: 10pt;"><br />Earlier in June electroCore reported preliminary results of a multicentre, randomised, trial across Europe. The trial was found to have met its primary endpoint of statistical significance in reducing the number of cluster headache attacks when compared with the standard of care.

Accordingly, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), the regulating agency that certifies Primary and Comprehensive Stroke Centres, requires that these institutions establish written care protocols to guide performance in the emergency care of acute ischaemic stroke, a press release from SNIS states.</span><br /><br /><span style="font-size: 10pt;">The study details a 2012 initiative by VUMC, an Advanced Certification Comprehensive Stroke Center, to significantly revise its stroke care protocol. &ldquo;Our ultimate goal was to develop an enhanced protocol that eliminates variability in our process, streamlines care to achieve necessary efficiencies, and improves time delays to improve the potential for better patient outcomes,&rdquo; said J Mocco, associate professor of Neurosurgery, Vanderbilt University Medical Center.</span><br /><br /><span style="font-size: 10pt;">The new protocol specifies three phases of activities involved in patient assessment and treatment decisions, as well as corresponding communication to relevant physicians at every phase. Specific measurements that map to the three phases include: time from patient arrival to CT scanning; time from patient arrival to neurology evaluation of diagnostics; and time from patient arrival to treatment with intravenous tissue plasminogin activator (IV tPA). Data was obtained over four separate three-month time periods pre- and post-protocol for comparison (pre-implementation of protocol: January&ndash;March 2012, and post-implementation of protocol: August&ndash;October, 2012; January&ndash;March, 2013; and September &ndash; November, 2013). &ldquo;These categories had been measured as part of our original protocol," continued Mocco, "however, we saw an opportunity to focus attention on some of the sub-processes within each that typically do not command attention, but, if addressed, could make a meaningful difference in quality improvement and the overall result.&rdquo;</span><br /><br /><span style="font-size: 10pt;">Post-implementation of the protocol, an analysis across all categories showed notable progress, with average time from patient arrival to CT scanning decreasing from 40.4 to 13 minutes; average time from patient arrival to neurology evaluation of diagnostics decreasing from 34.3 to 8.3 minutes; and average time from patient arrival to IV tPA treatment decreasing from 67.6 to 46.5 minutes.&nbsp; The latter means that VUMC has successfully met the JCAHO-stipulated metric of 60 minutes for "patient arrival to IV tPA."</span></p> <p><span style="font-size: 10pt;">"The success of this new protocol can truly be attributed to a multidisciplinary effort on the part of all of our physicians and other clinicians who work within the always complex and dynamic environment of emergency stroke care with ever-changing variables, all for the purpose of providing the best care for our stroke patients," said Scott Zuckerman, a senior neurosurgery resident who helped plan and lead the implementation of the protocol.</span><br /><br /><span style="font-size: 10pt;">Mocco added, &ldquo;First and foremost, it illustrates the value of customised written protocols that consider all of the nuances associated with any one hospital&rsquo;s emergency stroke care process. Ours is certainly not a one-size fits all solution. Every stroke centre has to tailor its protocols to its own culture and resources.&nbsp; But, ultimately, we hope our experience will be of benefit to other stroke centres that are considering or just beginning a written protocol initiative to fulfill their mission of offering the highest standard of stroke care to their patients.&rdquo;</span></p></div> NeuroPace RNS system receives approval from CMS for new Technology Add-On Payments 2014-08-06T11:18:00Z 2014-08-06T11:18:00Z <div id="ImageMain86" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction86" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>NeuroPace has announced that the Centers for Medicare &amp; Medicaid Services (CMS) has approved New Technology Add-on Payments (NTAP) for the RNS system, the world&rsquo;s only commercially available implantable closed-loop responsive neurostimulator system.

It is approved as a treatment for adults with partial onset seizures with one or two seizure onset zones whose seizures have not been controlled with two or more antiepileptic drugs.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We are grateful CMS recognises the substantial benefits the RNS system has provided to patients and the need for patients who suffer from uncontrolled seizures to have access to this therapy,&rdquo; says Frank Fischer, chief executive officer at NeuroPace. &ldquo;Epilepsy centres have moved quickly since PMA approval to make the RNS system available. To date, 35 Comprehensive Epilepsy Centers that meet all the qualifications for the highest level of epilepsy care have completed required training and are able to implant the RNS system.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Approximately 2.3 million adults in the United States have active epilepsy, and one-third live with seizures because existing therapies have not provided seizure control. Many people with uncontrolled seizures have or are eligible for Medicare disability benefits. Approval of the NTAP will significantly improve patient access to this new technology.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />As a closed-loop system, the RNS System monitors the brain&rsquo;s own signals, interprets those signals, provides stimulation when needed, and then assesses the brain&rsquo;s response. The breakthrough aspect of the RNS system is its advanced detection and stimulation capabilities. This is unlike all other existing neurostimulation therapies, which continuously or intermittently stimulate the brain without determining the need for treatment or monitoring the response.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The RNS system has been evaluated in three clinical trials, including a prospective, randomised, double-blinded, sham stimulation controlled pivotal study. Results of the clinical trials demonstrate that the substantial clinical improvements experienced by patients over the short- and long-term are durable over many years of therapy. At this time, some patients have been treated with the RNS system for over ten years, and more than 1,500 patient years of experience with responsive neurostimulation have been accumulated to date.</span></p></div> Accenture and Philips announce proof of concept app for ALS patients 2014-08-05T11:49:00Z 2014-08-05T11:49:00Z <div id="Introduction87" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Royal Philips and Accenture have announced that they have developed proof of concept software connecting a wearable display to Emotiv Insight Brainware that could ultimately give more independence to patients with amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases. Affecting more than 400,000 people per year, ALS, also known as Lou Gehrig&rsquo;s disease, impairs brain and spinal cord nerve cells, gradually diminishing voluntary muscle action. Late-stage patients often become totally paralysed while retaining brain functions.</strong></span></p> </div><div id="Text187" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This proof of concept exemplifies how people, devices, data and technology could be brought together quickly to connect beyond the hospital walls in a way that can potentially help improve the quality of life for patients, wherever they are in their journey,&rdquo; says Jeroen Tas, chief executive officer, Healthcare Informatics Solutions and Services for Philips. &ldquo;Philips will continue to collaborate with innovative technology companies such as Accenture to explore new wearable and sensor solutions that change peoples&rsquo; lives and create a healthier future.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><strong><br />How it works</strong></span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />When a wearable display and the Emotiv Insight Brainware, which scans EEG brainwaves, are connected to a tablet, users can issue brain commands to control Philips products including Philips Lifeline Medical Alert Service, Philips SmartTV (with TP Vision), and Philips Hue personal wireless lighting. The tablet also allows control of these products using eye and voice commands. In both cases, a person could communicate preconfigured messages, request medical assistance, and control TVs and lights. Accenture and Philips developed the software that enables the integration and interaction between these multiple technologies.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The proof of concept application demonstrates how existing technology could be used to transform the quality of life for ALS patients. When patients lose muscle control and eye tracking ability, they can still potentially operate the Philips suite of connected products in their home environment through brain commands. The Emotiv technology uses sensors to tune in to electric signals produced by the wearer&rsquo;s brain to detect, in real-time, their thoughts, feelings and expressions. The wearable display provides visual feedback that allows the wearer to navigate through the application menu.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The Accenture Technology Labs in San Jose, California, USA collaborated with the Philips Digital Accelerator Lab in the Netherlands to create the software to interact with the Emotiv Insight Brainware and the wearable display.

The first 12 patients received injections in the cervical region of the spinal cord only, where the stem cells could help preserve breathing function, in escalating doses ranging from five injections of 200,000 cells per injection, to 20 injections of 400,000 cells each. The final three patients in the trial received both cervical and lumbar injections, for a total of 40 injections of 400,000 cells each, or a total of 16 million cells transplanted. In contrast, the final three patients in the phase I trial received the maximum 15 injections of 100,000 cells each, for a total of 1.5 million cells. The trial will continue until six months past the final surgery, at which point the data will be evaluated.</strong></span></p> </div><div id="Text191" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;We are all extremely pleased to have completed the transplantations in this historic phase II trial," says principal investigator, Eva Feldman, director of the A Alfred Taubman Medical Research Institute and director of Research of the ALS Clinic at the University of Michigan Health System. &ldquo;By early next year, we will have six-month follow up data on the last patients who received what we believe will be the maximum safe tolerated-dose for this therapy.

Neurointerventionists typically accomplish this approach by manually directing the catheter and visualising its progress under standard X-ray guidance.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />With MARC, study authors sought to understand if a remote-controlled catheter under Magnetic Resonance Imaging (MRI) guidance could more effectively accomplish manoeuvring through complex vessel anatomy, which would ultimately allow improved visualisation of the brain tissue affected during a stroke. &ldquo;Given that MRI is the gold standard by which we determine brain tissue viability, it is exciting that we potentially now have new MRI-compatible technology that enables us, while treating a stroke, to make real-time assessments about whether brain tissue is dead or alive,&rdquo; says Steven Hetts, lead study author and associate professor of Radiology at the University of California, San Francisco, USA. &ldquo;The implications are numerous, including improved medical decision-making, which would naturally result in optimising patient safety and clinical outcomes.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />To assess the performance of MARC, Hetts and his colleagues aimed to determine mean procedure times and success data for a custom, clinical-grade MARC prototype under MRI guidance as compared to a manually-navigated catheter, under both MRI and conventional x-ray guidance - each procedure utilising a cryogel vascular model designed to simulate the main and branch blood vessels in a living human. The MRI-guided procedures were performed at 1.5T (magnetic field strength of a standard clinical MRI scanner) using a balanced steady-state free precession sequence in the type of clinical MRI scanner available in most hospitals.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Results showed that MARC was clearly visible under MRI guidance and was used to successfully complete 192 (80%) of 240 total turns around blood vessels as compared to the manually- directed catheter under both MRI and x-ray guidance, at 144 (60%) of 240 total turns and 119 (74%) of 160 total turns, respectively. MARC also was faster than the manually directed catheter under MRI, with a mean procedure time of 37 seconds per turn as compared to 55 seconds, but comparable to the manually directed catheter under X-ray guidance which required a mean of 44 seconds for each turn. When assessing the time required to navigate the various angles of branch vessels at turns of 45&deg;, 60&deg;, and 75&deg;, MARC proved to be faster than the manually-directed catheter under MRI guidance.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Given that the success of neurointerventional stroke treatment is directly tied to how fast and accurately physicians can eliminate the impact of a clot and restore blood flow to viable portions of the brain, technology that facilitates this objective stands to be transformative,&rdquo; says Hetts. &ldquo;By proving that MRI-guided neurointervention could be more effective than current standard approaches to stroke treatment, we are taking a significant step forward in the advancement of our field.&rdquo;</span></p></div> Los Angeles medical team performs California’s first auditory brainstem implant surgery on toddler 2014-08-01T12:39:00Z 2014-08-01T12:39:00Z <div id="ImageMain95" style="clear:both;" align="center"><a href=""><img src="" border="0" vspace="5" /></a></div><div id="Introduction95" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A Los Angeles team of scientists and surgeons from Keck Medicine of the University of Southern California (USC),Children&rsquo;s Hospital Los Angeles&nbsp;(CHLA) and Huntington Medical Research Institutes (HMRI) reported that sound registered in the brain of a deaf Canadian boy for the first time after doctors activated a hearing device that had been surgically implanted in his brainstem.</strong></span></p> </div><div id="Text195" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Auguste Majkowski, 3, is the first child in the United States to undergo an auditory brainstem implant (ABI) surgery in a US Food and Drug Administration (FDA)-approved trial supported by a National Institutes of Health (NIH) clinical trial grant. On 12 June, six weeks after surgery at CHLA, the device was activated with positive results at the Department of Otolaryngology &ndash; Head &amp; Neck Surgery clinic at Keck Medicine of USC.</span></p> <p><span style="font-size: 10pt;"><br />Auguste&rsquo;s surgery, device activation and future behavioural study are part of a five-year clinical trial in which 10 devices will be implanted in deaf children under the age of five and studied over the course of three years. The Los Angeles study, co-led by audiologist Laurie Eisenberg, and surgeon Eric Wilkinson, is the only in the United States to be supported by the NIH.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our Los Angeles-based team has been at the forefront of ABI technology development since it came into use in the late 1970s for adults, so it is especially gratifying to help break the &lsquo;sound barrier&rsquo; once again; this time, for children who previously could not hear,&rdquo; says Eisenberg, a Keck School of Medicine of USC otolaryngology professor. &ldquo;Surgeons outside the United States have been doing ABI surgeries in children for 10 years, but there has never been a formal safety or feasibility study under regulatory oversight. Our team is writing the manuals for all the procedures for this technology, and we have a top-notch multidisciplinary team in place to carry out the research.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />The surgical team that performed the operation at Children&rsquo;s Hospital included Wilkinson, HMRI research scientist and neurotologist at House Clinic; HMRI research scientist and House Clinic neurosurgeon Marc Schwartz, and paediatric neurosurgeon&nbsp;Mark D Krieger, Billy and Audrey Wilder chair, Division of Neurosurgery&nbsp;at CHLA. Attending the surgery was also Vittorio Colletti, of the University of Verona Hospital, Verona, Italy, who has performed the most ABI surgeries on children overseas and is a collaborator on the study.</span></p> <p><span style="font-size: 10pt;"><br />The study&rsquo;s goal is to establish safety and efficacy protocols for the surgery and subsequent behavioural mapping procedures that doctors in the United States can then later utilise once the surgery is approved for children in the USA.</span></p> <p><span style="font-size: 10pt;">&ldquo;Hundreds of children in the USA can benefit from ABI surgery,&rdquo; says Krieger, who also is associate professor of clinical neurosurgery at the Keck School of Medicine of USC. &ldquo;These children would otherwise never hear or develop verbal speech in their lives.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Auguste was the first child accepted into the Los Angeles study. Thirty-six days after the May 6 surgery at CHLA, his parents watched as audiologists Margaret Winter, and Jamie Glater, from the USC Center for Childhood Communication activated the device implanted in Auguste&rsquo;s brainstem. When Winter delivered tiny pulses of electric current to the electrodes in his brain, the toddler lifted his head indicating he heard a sound.</span></p> <p><span style="font-size: 10pt;"><br />Auguste has been deaf since birth. At 22 months, he underwent a bilateral cochlear implant, which uses electrodes to stimulate auditory nerves, but the device did not help him hear because he does not have a cochlear, or hearing, nerve. Auguste travelled with his parents, Sophie and Christophe, from Montreal to Los Angeles to participate in the clinical trial. The NIH grant covers the costs of the device, procedure and subsequent testing. To qualify for participation, patients must show that standard treatment such as hearing aids and cochlear implants have been ineffective.</span></p> <p><span style="font-size: 10pt;"><br />During the six-hour surgery in May, doctors made an incision by Auguste&rsquo;s right ear and removed his right cochlear implant before implanting the ABI device on his brainstem. The ABI device has external and internal parts. The external parts, which consist of a processor with a microphone and transmitter, transform sound into electrical signals and transmit the signals to an internal receiver that is part of the electrode array. The electrode array is placed on the cochlear nucleus of the brainstem. The procedure is considered revolutionary because it stimulates neurons directly at the human brainstem, bypassing the inner ear entirely.</span></p> <p><span style="font-size: 10pt;"><br />The young children who had ABIs implanted outside the United States now have the potential to understand speech, but, in the United States, the device is FDA-approved for use only in patients 12 years or older with neurofibromatosis type II, an inherited disease that causes a non-malignant brain tumour on the hearing nerve. It has shown limited effectiveness in adults, however, and scientists believe that the device would be more effective in young children, when their brains are more adaptable. The clinical trial will attempt to prove that this surgery is safe in young children and allow researchers to study how the brain develops over time and how it learns to hear sound and develop speech.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The children in this study are under five years of age,&rdquo; says Keck School of Medicine of USC Professor Robert V Shannon, an investigator for the trial and leading scientist in the development of ABI technology since 1989. &ldquo;When a child is born, their ear is hard-wired for sound but the brain has to learn how to perceive sound and speech from the information coming up the hearing pathway. If the ear is not providing sound information to the brain, the hearing part of the brain does not develop properly. The ABI provides sound to these pathways so they grow and develop with the child.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />After the devices are implanted, the Los Angeles-based researchers will study how the brain develops over time as it incorporates sound and speech. If the clinical trial is successful, children across the United States will be able to benefit from surgical and audiology techniques and safety and efficacy protocols developed in the study.</span></p></div> Medtronic completes acquisition of Visualase 2014-07-28T14:54:00Z 2014-07-28T14:54:00Z <div id="Introduction96" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Medtronic has announced that it has completed the acquisition of Visualase, a&nbsp;privately held company based in Houston, USA, that develops and markets an FDA-approved MRI-guided laser and image guided system for minimally invasive neurosurgeries, including surgical thermal ablation.</strong></span></p> </div><div id="Text196" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Medtronic will add Visualase&rsquo;s MRI-guided laser ablation system to its portfolio of therapies for treating neurological conditions within its Surgical Technologies business and will integrate the technology into its broader neuroscience offerings.

NeuroPace received premarket approval (PMA) from the US Food and Drug Administration (FDA) for the RNS System in November 2013. It is approved as a treatment for adults with partial onset seizures with one or two seizure onset zones whose seizures have not been controlled with two or more antiepileptic drugs.</span></p> <p><br /><span style="font-size: 10pt;">Through the DARPA RAM research, NeuroPace and other collaborators will gain fundamental knowledge regarding the restoration of memory. The company believes this research may expand the clinical applications of the RNS system beyond the treatment of epilepsy, as well as provide the understanding necessary to inform the development of future devices that expand the capabilities of responsive neurostimulation. This collaborative effort will advance the field of brain research and closed-loop neurostimulation applications. A portion of the DARPA project will involve epilepsy patients implanted with the RNS system at seven Comprehensive Epilepsy Centers and will be led by Barbara Jobst, professor of Neurology at Dartmouth, and Martha Morrell, chief medical officer at NeuroPace and clinical professor of Neurology at Stanford University. A separate part of the project will begin with epilepsy patients implanted with the RNS system at UCLA with Itzhak Fried serving as the principal investigator.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Using the RNS system, we will be able to immediately explore ways in which brain stimulation can restore memory function in patients with epilepsy. Insights derived from these early studies will help to guide future research in patients with other neurological disorders that result in memory loss,&rdquo; says Michael Kahana, principal investigator at the University of Pennsylvania.</span></p> <p><br /><span style="font-size: 10pt;">As a closed-loop system, the RNS system monitors the brain&rsquo;s own signals, interprets those signals, provides stimulation when needed, and then assesses the brain&rsquo;s response. The breakthrough aspect of the RNS system is its advanced detection and stimulation capabilities. This is unlike all other existing neurostimulation therapies, which continuously or intermittently stimulate the brain without determining the need for treatment or monitoring the response.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;The RNS system is the only commercially available product that continuously monitors the brain&rsquo;s electrical signals, delivers stimulation only when needed and then monitors the response,&rdquo; says Frank Fischer, chief executive officer at NeuroPace. &ldquo;This capability is critical to the research phase of projects like the DARPA RAM programme.

Plegridy is dosed once every two weeks and is administered subcutaneously with the Plegridy pen, a new ready-to-use autoinjector, or a prefilled syringe.</strong></span></p> </div><div id="Text199" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Plegridy, the only pegylated interferon approved for use in relapsing-remitting multiple sclerosis, has been proven to significantly reduce important measures of disease activity, including number of relapses, MRI brain lesions, and disability progression.</span></p> <p><br /><span style="font-size: 10pt;">The European Commission approval of Plegridy is based on results from one of the largest pivotal studies of a beta interferon conducted, <a href=";rank=13" target="_blank"><strong>ADVANCE</strong></a>, which involved more than 1,500 patients with relapsing forms of multiple sclerosis.</span></p> <p><br /><span style="font-size: 10pt;">In the ADVANCE clinical trial, Plegridy, dosed once every two weeks, significantly reduced annualised relapse rate (ARR) at one year by 36% compared to placebo (p=0.0007).</span></p> <p><br /><span style="font-size: 10pt;">Plegridy reduced the risk of sustained disability progression confirmed at 12 weeks by 38% (p=0.0383) and at 24 weeks by 54% (p=0.0069, post-hoc analysis). In addition, the number of gadolinium-enhancing [Gd+] lesions was significantly reduced by 86% (p&lt;0.0001) compared to placebo.</span></p> <p><span style="font-size: 10pt;"><br />Results over two years of ADVANCE confirm that its robust efficacy was maintained beyond the placebo-controlled first year of the study.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;The safety and efficacy that Plegridy has demonstrated, combined with its less frequent dosing schedule offers multiple sclerosis patients an option to put their treatment in the background for longer stretches of time,&rdquo; says Bernd C Kieseier, Heinrich-Heine&nbsp;Universit&auml;t, Dusseldorf.</span></p> <p><br /><span style="font-size: 10pt;">The safety and tolerability profile of peginterferon beta-1a observed in ADVANCE&nbsp;was consistent with that of established multiple sclerosis interferon therapies. The most commonly reported adverse drug reactions with peginterferon beta-1a treatment (incidence &ge;10% and at least 2% more frequent on peginterferon beta-1a than on placebo) were injection site reaction, flu-like illness, fever, headache, muscle pain, chills, injection site pain, weakness, injection site itching, and joint pain.</span></p> <p><br /><span style="font-size: 10pt;">Plegridy is the fifth therapy to be offered by Biogen Idec to people living with multiple sclerosis.</span></p></div> US$1 million Career Development Award grant for glioblastoma research with ThermoDox and HIFU 2014-07-22T10:14:00Z 2014-07-22T10:14:00Z <div id="Introduction100" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Celsion Corporation has announced that its ongoing collaboration with Costas Arvanitis of Brigham and Women&rsquo;s Hospital, a teaching affiliate of&nbsp;Harvard Medical School, has been expanded through the recent award of a&nbsp;US$1 million&nbsp;Career Development Award from the National Institutes of Health&rsquo;s Center for Biomedical Imaging and Bioengineering (NIBIB).</strong></span></p> </div><div id="Text1100" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The grant will support preclinical studies evaluating ThermoDox, the company&rsquo;s heat-activated liposomal encapsulation of doxorubicin, in combination with High Intensity Focused Ultrasound (HIFU), for the treatment of brain tumours. The grant, titled &ldquo;Controlled Delivery and Release of Chemotherapy in Brain Tumours with FUS&rdquo; provides on average of&nbsp;US$200,000&nbsp;in annual funding for five years, and will be used to advance preclinical development of ThermoDox for the treatment of brain cancers, including glioblastoma multiforme, under the company&rsquo;s&nbsp;January 2014&nbsp;collaboration with Brigham and Women&rsquo;s Hospital, Harvard Medical School.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;This peer-reviewed grant award builds upon our ongoing collaborative work to explore treatments for brain tumours,&rdquo; says Costas D Arvanitis, Brigham and Women&rsquo;s Hospital,&nbsp;Harvard Medical School. &ldquo;Delivering chemotherapeutic agents across the blood-brain barrier is particularly challenging, but in recent years we have discovered that this could be achieved using focused ultrasound, including enhanced delivery of liposomal doxorubicin.&nbsp;We are hopeful that this grant will allow us to determine the potential utility of a promising therapeutic application for one of the most insidious cancers - glioblastoma.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Glioblastoma is a highly aggressive and deadly form of brain cancer for which there are few treatment options,&rdquo; says&nbsp;Michael H Tardugno, Celsion&rsquo;s president and chief executive officer.&nbsp;&ldquo;Working with a prominent cancer research group like Dr Arvanitis and his team, combined with the financial support of the NIH, will help accelerate the research required to elucidate the potential of ThermoDox combined with HIFU in this difficult to treat cancer, and provide a path forward for larger, more comprehensive phase II studies.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">If promising results are obtained from these phase I studies, a phase II grant application will be submitted to include more comprehensive studies of ThermoDox and HIFU for the treatment of glioblastoma multiforme brain tumours.</span></p></div>
