How deep-brain stimulation reshapes neural circuits in Parkinson's disease

Posted: Published on April 13th, 2015

UC San Francisco scientists have discovered a possible mechanism for how deep-brain stimulation (DBS), a widely used treatment for movement disorders, exerts its therapeutic effects. Few medical treatments show results as rapid and dramatic as those seen with DBS, in which surgically implanted devices deliver electrical pulses to inner brain structures involved in movement. In most Parkinson's disease (PD) patients who receive the treatment, symptoms of slow movement, tremor, and rigidity sharply diminish soon after the stimulation device is activated, and quickly return if the device is turned off. But surprisingly, there has been very little understanding of precisely why and how DBS works so well--a lack of knowledge that has held back efforts to further improve the therapy. Despite the great success of DBS, some significant problems remain. Customizing the stimulation delivered by DBS devices for each patient to maximally reduce symptoms is challenging and time-consuming. And a minority of patients never obtains the full benefit their physicians expect. With a better understanding of how DBS acts on brain circuits, researchers hope to address these shortcomings and make DBS an even more effective treatment. The new research, published online April 13, 2015 in Nature Neuroscience, reveals that DBS keeps … Continue reading

I Learned The Hard Way That Concussion Isn't Just For The Young

Posted: Published on April 13th, 2015

I think I knew what was happening even before my head bounced off the hard kitchen counter on its way to the even harder stone floor. I was rapidly losing my connection with reality. My wife, Tabitha, later estimated that I was out for 10 minutes. When I emerged from unconsciousness I heard the sirens on the street in front of the house. It seemed as if half of Tucson's fire department was streaming through the front door. I was scared. At my age, which is old, you laugh at any childlike faith in your immortality. In this case, what brought on the unconsciousness was apparently a quick turn of my head while reaching for an onion to peel for the night's dinner, followed by the knockout blow from hitting the floor. I was scared. At my age, which is old, you laugh at any childlike faith in your immortality. An enormous hook and ladder and an ambulance were drawn up in front of the house, sirens winding down. The commotion was embarrassing, but it was comforting to know that my wife was in the next room, had called for help, and that 911 had responded to her call as … Continue reading

Gilenya data at AAN to highlight Novartis leadership in innovation with new MS assessment methods to benefit patients …

Posted: Published on April 13th, 2015

New analysis will confirm high efficacy of Gilenya in achieving 'no evidence of disease activity' (NEDA4) in previously-treated highly-active RMS patients Separate analyses will show adding brain shrinkage to an existing assessment tool enhances ability to predict disability progression in relapsing MS (RMS) Early data on a novel method to assess motor function in patients with MS and its potential clinical application will also be presented at AAN Basel, 13 April 2015 - Novartis announced today new Gilenya analyses to be presented at the 67th American Academy of Neurology (AAN) Annual Meeting in Washington, DC, USA from April 18-25, 2015, showing how Novartis is advancing methods assessing the impact of relapsing multiple sclerosis (RMS) for patients and physicians. Data will show how adding brain shrinkage (brain volume loss) to an existing tool to assess MS disease activity (m-Rio) will give a more precise prediction of the likelihood of future disability progression. Accurate assessment of disease activity is key to guide treatment decisions in RMS. A pooled analysis from the two-year phase III FREEDOMS and FREEDOMS II trials will further confirm Gilenya's high efficacy in previously-treated patients with highly-active RMS in achieving 'no evidence of disease activity' (NEDA4) across four key … Continue reading

Horizon gets FDA fast track status for actimmune to treat Friedreich's ataxia

Posted: Published on April 13th, 2015

PBR Staff Writer Published 13 April 2015 Irish biopharmaceutical firm Horizon Pharma has granted fast track designation from the US Food and Drug Administration (FDA) for actimmune (interferon gamma-1b) to treat Friedreich's ataxia (FA), a degenerative neuro-muscular disorder. In February 2015, the company submitted the investigational new drug (IND) application for Actimmune in the treatment of FA. The company has also announced plans to initiate a Phase III trial in the second quarter in collaboration with the Friedreich's Ataxia Research Alliance (FARA) and a sub-set of FARA's Collaborative Clinical Research Network (CCRN) study centers in FA. Horizon Pharma chairman, president and chief executive officer Timothy Walbert said: "We commend the FDA for granting fast track designation for actimmune in Friedreich's ataxia to potentially help treat patients suffering from this debilitating disorder, for which there are no FDA approved treatments available. "We look forward to continuing our ongoing clinical development program as we evaluate actimmune in this patient population." Actimmune is a biologically manufactured protein similar to one the body makes naturally to help prevent infection. Currently, actimmune is approved by the FDA for use in two rare diseases and it is indicated to reduce the frequency and severity of serious … Continue reading

Scientists develop cardiac cells using stem cells

Posted: Published on April 13th, 2015

For millions of people around the world, who suffer from various diseases, research in stem cells offers a ray of hope. Scientists of the city-based Indian Institute of Science have used stem cells of a mouse to culture cardiac cells. Explaining the research, Polani B. Seshagiri said their research over the past seven years has helped develop cardiac cells that function and beat in rhythms identical to the original cell. Speaking on Stem Cell Awareness Day recently, Prof. Seshagiri said stem cells had several advantages and could cure human disorders and diseases, which could not be cured by conventional approaches. However, he warned that there was a need to be aware of the limitations of stem cells. Sudarshan Ballal, Medical Director, Manipal Health Enterprise, said stem cells had enormous potential as they never die and could be converted into any cell. Stem cells can be converted into organs and maybe years later, organs can be cultivated in labs through stem cell, he said. Elaborating further, he said a stem cell could be compared to a bicycle, which could turn into car, motorbike and spaceship based on the environment and conditions. Nazeer Ahmed, Deputy Drug Controller of Karnataka, said they were … Continue reading

Aetna, Cigna balk as Angelina effect spurs genetic cancer testing

Posted: Published on April 13th, 2015

Medical researchers call it the "Angelina Effect," the surge in demand for genetic testing attributable to movie star Angelina Jolie's public crusade for more aggressive detection of hereditary breast and ovarian cancer. But there's a catch: Major insurance companies including Aetna, Anthem and Cigna are declining to pay for the latest generation of tests, known as multi-gene panel tests, Reuters has learned. The insurers say that the tests are unproven and may lead patients to seek out medical care they don't need. That's a dangerous miscalculation, a range of doctors, genetic counselors, academics and diagnostics companies said. While they acknowledge that multi-gene tests produce data that may not be useful from a diagnostic standpoint, they say that by refusing or delaying coverage, insurance companies are endangering patients who could be undergoing screenings or changing their diets if they knew about the possible risks. The tests have come a long way since Jolie, 39, went public in 2013, revealing that she underwent a double mastectomy after a genetic test found she carried mutations in the BRCA1 and BRCA2 genes, indicating a high risk of breast and ovarian cancer. She disclosed last month that she had her ovaries and fallopian tubes removed. … Continue reading
