UR Achieves Lewy Body Disorder Association Center of Excellence Status

Monday, September 17, 2018

The University of Rochester movements disorders division has been designated as a lead body disorder Association research center of excellence.  This designation is obtained at the understanding of the disorder, educating patients and caregivers, and investigating possible research activities specifically aimed at this difficult disease.  While many people are always involved in obtaining such a designation, special kudos go to Dr. Katie Amodeo who has been instrumental in our success with this endeavor and will continue to play a key role in developing a successful UR program focused on the rapidly growing field of neurodegenerative diseases characterized by Parkinsonism and Dementia.

Drug Shows Promise in Slowing Multiple Sclerosis

Wednesday, September 5, 2018

Research appearing in the New England Journal of Medicine could herald a new treatment approach for individuals with multiple sclerosis (MS) if confirmed in future studies. The results of a clinical trial, which involved researchers from the University of Rochester Medical Center (URMC), showed that the drug ibudilast slowed the brain shrinkage associated with progressive forms of the disease.

“These results indicate that ibudilast may be effective in protecting the central nervous system and slowing the damage to the brain that is caused by MS,” said URMC neurologist Andrew Goodman, M.D., a co-author of the study who served on the national steering committee for the Phase II clinical trial, dubbed SPRINT-MS. “While more clinical research is necessary, the trial’s results are encouraging and point towards a potential new type of therapy to help people with progressive MS.”

MS is a neurological disorder in which the body’s own immune system attacks myelin, the fatty tissue that insulates the nerve fibers in the brain and spinal cord.  These attacks are caused by inflammation which damages myelin, disrupting communication between nerve cells and leading to cognitive impairment, muscle weakness, and problems with movement, balance, sensation, and vision. MS usually presents with a relapsing-remitting course, in which symptoms occur then disappear for weeks or months and then may reappear, or primary and secondary progressive courses, which are marked by a gradual decline in function.

Richard Barbano Co-Authors New Guideline for Managing Consciousness Disorders

Thursday, August 16, 2018

A new practice guideline update for the diagnosis and ongoing medical and rehabilitative care of individuals in a vegetative or minimally conscious state has a result of a brain injury have been published by the American Academy of Neurology, the American Congress of Rehabilitation Medicine, and the National Institute on Disability, Independent Living, and Rehabilitation Research.

URMC neurologist Richard Barbano, M.D., Ph.D., was part of a team of physicians and researchers who prepared the new guideline, which appears in the journal Neurology

The experts carefully reviewed all of the available scientific studies on diagnosing, predicting health outcomes, and caring for people with disorder of consciousness, focusing on evidence for people with prolonged disorders of consciousness – those cases lasting 28 days or longer.

The guideline recommends that a clinician trained in the management of disorder of consciousness, such as a neurologist or brain injury rehabilitation specialists, should do a careful evaluation and the evaluation should be repeated several times early in recovery. 

Additional findings include:

  • The outcomes for patients with prolonged disorder of consciousness differ greatly.  It is estimated that one in five people with severe brain injury from trauma will recover to the point where they can live at home and care for themselves without assistance.
  • There is moderate evidence that patients with a brain injury from trauma will fare better in terms of recovery than a person with a brain injury from another cause.
  • Very few treatments for disorder of consciousness have been carefully studied.  However, moderate evidence shows that the drug amantadine can hasten recovery in patients with disorder of consciousness after a traumatic brain injury when used within one to four months after the injury.

NIH Extends URMC’s Role in Network to Advance Neurological Care

Thursday, July 26, 2018

National Institute of Neurological Disorders and Stroke (NINDS) has extended the University of Rochester Medical Center’s (URMC) membership in the Network for Excellence in Neuroscience Clinical Trials, or NeuroNEXT, which was created to accelerate clinical research involving new treatments for neurological disorders.  The $1.5 million grant will provide patients in the region access to cutting-edge experimental therapies and continue the Medical Center’s key role in helping bring new drugs to market. 

“Neurological diseases are some of the most challenging in all of medicine and the process of translating promising discoveries into new treatments requires building partnerships across many institutions in order to create the infrastructure necessary to recruit patients and run multi-site clinical trials,” said Robert Holloway, M.D., M.P.H., chair of the URMC Department of Neurology and principal investigator of the URMC NeuroNEXT site. “The Medical Center has a long history in the field of experimental therapeutics and we are proud to be a part of NeuroNEXT and to support efforts that will make clinical research better, faster, and more efficient in the quest to aid patients and families affected by neurological disease.”

In 2011, URMC was one of the original 25 institutions selected to participate in NeuroNEXT.  The network was created to streamline the operations of neuroscience clinical trials and help increase the number of new treatments that get into clinical practice. The program is designed to encourage collaborations between academic centers, disease foundations, and industry.

Over the last five years, URMC has been involved in NeuroNEXT studies involving the testing of new drugs for myasthenia gravis, multiple sclerosis, Huntington’s disease, stroke, brain cancer, and neuropathy.  “We could not have accomplished this without the phenomenal talent and dedication of our faculty, study coordinators, and research teams.” said Erika Augustine, M.D., M.S., co-Investigator on the grant. 

“One of the advantages of NeuroNEXT, and something that makes it unique, is the network’s ability to quickly mobilize a group of specialists from a certain disease area to initiate a clinical study when opportunities emerge for trials,” said Robin Conwit, M.D., program director at NINDS. “The structure of NeuroNEXT, with its broad focus across neuroscience clinical studies, has the potential to reach many individuals who are affected by brain disorders.”  

The Medical Center’s site – dubbed UR NEXT – has made significant contributions to the success and vitality of the network.  URMC is the dominant provider of comprehensive neurological care in upstate New York with growing referral networks that have a regional, national, and international reach.  This breadth of geographic reach and specialization of services has resulted in the Medical Center being one of the network’s leading performers in terms of clinical trial recruitment and performance.

The Medical Center is also home to the Experimental Therapeutics in Neurological Disease post-doctoral training program now entering its 28th year of continuous funding from the National Institutes of Health, and the Center for Health + Technology (CHeT), a unique academic-research organization with decades of experience in development, management, and operation of multi-site clinical trials. 

“The complexity of neurological diseases and the ever evolving nature of scientific innovation in this field mean that we must look always to the future and build the teams that turn new discoveries into new ways to diagnose, treat, and prevent these diseases,” said Jonathan Mink, M.D., Ph.D., co-investigator on the grant who is leading Rochester’s training of its investigators. “The UR NEXT grant will help us train the next generation of experts in leading and conducting multi-center clinical trials,”

In addition to URMC’s role as a NeuroNEXT site, the Medical Center has two additional key roles supporting the national network. The URMC Clinical Materials Services Unit – part of CHeT – provides logistical support and drug supply distribution services for NeuroNEXT clinical trials and UR Labs provides central laboratory services for the network.

AHA Grants Will Accelerate Search for New Stroke Therapies

Wednesday, June 27, 2018

A series of awards from the American Heart Association (AHA) to a team of researchers at the University of Rochester Medical Center (URMC) will focus on the development of new treatments to thwart the damage in the brain caused by stroke.

One of the research projects brings together experts in stroke, cardiovascular biology, platelet biology, and peptide chemistry. Marc Halterman, M.D., Ph.D., with the URMC Center for Neurotherapeutics Discovery, Scott Cameron, M.D., Ph.D., and Craig Morrell, D.V.M., Ph.D., with the URMC Aab Cardiovascular Research Institute, and Bradley Nilsson, Ph.D., with the University of Rochester Department of Chemistry will focus on the role that platelets play in acute brain injury and inflammation during stroke.

Platelets serve an important role in protecting against blood loss and repairing injured blood vessels. However, during a stroke the inflammatory properties of platelets can interfere with the restoration of blood flow once the clot in the brain is removed, particularly in micro-vessels, which can lead to permanent damage of brain tissue.

The research team will build synthetic peptides that activate platelets to study the phenomenon – which is called no-reflow – in an effort to identify specific switches within platelets that can be turned off and limit the cells’ inflammatory functions without blocking their ability to prevent bleeding.

Two AHA pre-doctoral fellowship awards Kathleen Gates and Jonathan Bartko in Halterman’s lab will support research that examines the link between an immune system response triggered by stroke in the lungs that can exacerbate damage in the brain and investigate the cellular mechanisms that determine whether or not brain cells die following stroke.

A final AHA award to the Halterman lab will seek to identify new drug targets by focusing on specific proteins activated during stroke that are suspected to play an important role in determining the survival of neurons.

Collectively, the AHA Collaborative Sciences Award, Pre-Doctoral, and Innovation awards represent $1.09 million in funding.

National Initiative Focuses on New Treatments for Lewy Body Dementia

Wednesday, April 18, 2018

The University of Rochester Medical Center (URMC) has been selected to participate in a national network created to develop new ways to diagnose and treat Lewy Body Dementia (LBD). The new initiative, which is being organized by the Lewy Body Dementia Association, will seek to raise awareness and advance research for this complex disorder.

“Lewy Body Dementia is a challenging, multifaceted disease and research to find new diagnostic tools and treatments is still in its infancy,” said URMC neurologist Irene Richard, M.D., who will serve as director of the URMC Lewy Body Dementia Association Research Center of Excellence. “This new network of will create an infrastructure of clinician researchers who understand the disease, are able to identify patients to participate in research, and have experience participating in multi-site clinical trials.”

LBD is a progressive brain disorder marked by abnormal protein deposits – called Lewy Bodies – in areas of the brain important for behavior, cognition, and motor control. This complex disease gives rise to a range of symptoms, including cognitive impairment, sleep disturbances, hallucinations, difficulty with blood pressure regulation, and problems with movement and balance. Individuals with the disease will often experience marked fluctuations in their levels of alertness and clarity of thought.

Robert Holloway & Benjamin George Study Regional Stroke Care

Monday, April 16, 2018

New research shows that stroke patients are increasingly being transferred out of smaller community and rural hospitals and sent to larger medical centers for their care and rehabilitation. While this is a positive sign for patients who need more advanced treatments, the trend has drawbacks in terms of cost and points to the need to improve the coordination of care between hospitals.

“The underlying goal of stroke care is to get the right person to the right hospital at the right time,” said University of Rochester Medical Center (URMC) neurologist Benjamin George, M.D., M.P.H., a co-author of the study which appears this month in the journal Neurology. “The findings of this study show that in recent years community-based hospitals are erring on the side of caution and transferring more patients from their emergency departments to larger hospitals. Given the high cost and burden associated with these transfers, striking a balance between cost and need is essential.”

Telehealth, Exercise the Focus of World Parkinson’s Disease Day

Tuesday, April 10, 2018

The University of Rochester Medical Center (URMC) is helping lead two advocacy efforts to increase awareness of the value of telehealth for individuals with Parkinson’s. These activities coincide with World Parkinson’s Disease Day on April 11.

“The prevalence of Parkinson’s disease is increasing and the number of people with the disease is expected to more than double in the next 20 years,” said neurologist Ray Dorsey, M.D., director of the URMC Center for Health + Technology (CHeT). “Telemedicine, along with other technologies, will be key to meeting this growing demand and will serve to expand access to quality care, help reduce the burden of caregivers, and potentially lower costs.”

CHeT is working with the Parkinson’s Foundation to advocate for telehealth by encouraging all of the Foundation’s 18 Centers of Excellence to provide at least one telemedicine visit on April 11. Dorsey has undertaken several studies over the last decade to demonstrate the feasibility and effectiveness of connecting Parkinson’s patients with specialists using telemedicine. Results of a recent study funded by the Patient-Centered Outcomes Research Institute demonstrated that telemedicine can successfully deliver quality care.

In addition, CHeT has partnered with Burn Along – an online video fitness and wellness platform that offers hundreds of classes at all fitness levels – in inviting individuals with Parkinson’s disease, caregivers, family members, and advocates to participate in free classes to raise awareness of the importance of exercising for Parkinson disease. Studies have shown that exercise can help keep the symptoms of Parkinson’s at bay and may even slow the progression of the disease.

Burn Along has joined with Dance for PD – a Brooklyn-based company that has created dance classes for people with Parkinson’s – to produce videos for distribution on their website. Individuals who sign up for the free classes with Burn Along on April 11 will have access to all of the site’s video content for the entire month of April.

Mobile Apps Could Hold Key to Parkinson’s Research, Care

Monday, March 26, 2018

By Mark Michaud

A new study out today in the journal JAMA Neurology shows that smartphone software and technology can accurately track the severity of the symptoms of Parkinson’s disease. The findings could provide researchers and clinicians with a new tool to both develop new drugs and better treat this challenging disease.

“This study demonstrates that we can create both an objective measure of the progression of Parkinson’s and one that provides a richer picture of the daily lived experience of the disease,” said University of Rochester Medical Center (URMC) neurologist Ray Dorsey, M.D., a co-author of the study.

One of the difficulties in managing Parkinson’s is that symptoms of the disease can fluctuate widely on a daily basis. This makes the process of tracking the progression of the disease and adjusting treatment a challenge for physicians who may only get a snapshot of a patient’s condition once every several months when they visit the clinic. This variation also limits the insight that researchers can gather on the effectiveness of experimental treatments.

The new study, which was led by Suchi Saria, Ph.D., an assistant professor of Computer Science at Johns Hopkins University, harnesses the capabilities of technology that already resides in most of our pockets all day, every day.

Researchers recruited 129 individuals who remotely completed a series of tasks on a smartphone application. The Android app called HopkinsPD, which was originally developed by Max Little, Ph.D., an associate professor of Mathematics at Aston University in the U.K., consists of a series of tasks which measure voice fluctuations, the speed of finger tapping, walking speed, and balance.

The Android app is a predecessor to the mPower iPhone app which was developed by Little, Dorsey, and Sage Bionetworks and has been download more than 15,000 times from Apple’s App Store since its introduction in 2015.

As a part of the study, the researchers also conducted in-person visits with 50 individuals with Parkinson’s disease and controls in the clinic at URMC. Participants were asked to complete the tasks on the app and were also seen by a neurologist and scored using a standard clinical evaluation tool for the disease. This aspect of the study was overseen by URMC’s Center for Health + Technology.

In Wine, There’s Health: Low Levels of Alcohol Good for the Brain

Friday, February 2, 2018

By Mark Michaud

While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease.

“Prolonged intake of excessive amounts of ethanol is known to have adverse effects on the central nervous system,” said Maiken Nedergaard, M.D., D.M.Sc., co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center (URMC) and lead author of the study. “However, in this study we have shown for the first time that low doses of alcohol are potentially beneficial to brain health, namely it improves the brain’s ability to remove waste.”

The finding adds to a growing body of research that point to the health benefits of low doses of alcohol. While excessive consumption of alcohol is a well-documented health hazard, many studies have linked lower levels of drinking with a reduced risk of cardiovascular diseases as well as a number of cancers.

Lungs Mays Hold Key to Thwarting Brain Damage after a Stroke

Wednesday, January 31, 2018

By Mark Michaud

The harm caused by a stroke can be exacerbated when immune cells rush to the brain an inadvertently make the situation worse. Researchers at the University of Rochester Medical Center (URMC) are studying new ways to head off this second wave of brain damage by using the lungs to moderate the immune system’s response.

“It has become increasingly clear that lungs serve as an important regulator of the body’s immune system and could serve as a target for therapies that can mitigate the secondary damage that occurs in stroke,” said URMC neurologist Marc Halterman, M.D., Ph.D. “We are exploring a number of drugs that could help suppress the immune response during these non-infection events and provide protection to the brain and other organs.”

Halterman’s lab, which is part of the Center for NeuroTherapeutics Discovery, has been investigating domino effect that occurs after cardiac arrest. When blood circulation is interrupted, the integrity of our intestines becomes compromised, releasing bacteria that reside in the gut into the blood stream. This prompts a massive immune response which can cause systemic inflammation, making a bad situation worse.

While looking at mouse models of stroke, his lab observed that a similar phenomenon occurs. During a stroke blood vessels in the brain leak and the proteins that comprise the wreckage of damaged neurons and glia cells in the brain make their way into blood stream. The immune system, which is not used to seeing these proteins in circulation, responds to these damage-associated molecular patterns and ramps up to respond. Mobilized immune cells make their way into the brain and, finding no infection, nevertheless trigger inflammation and attack healthy tissue, compounding the damage.

The culprit in this system-wide immune response is neutrophils, a white cell in the blood system that serves as the shock troops of the body’s immune system. Because our entire blood supply constantly circulates through the lungs, the organ serves as an important way station for neutrophils. It is here that the cells are often primed and instructed to go search for new infections. The activated neutrophils can also cause inflammation in the lungs, which Halterman suspects may be mistakenly identified as post-stroke pneumonia. The damage caused by activated neutrophils can also spread to other organs including the kidneys, and liver.
