In the Spotlight: Jacquie Kurland, Communication Disorders

Jacquie Kurland, Assistant Professor of Communication Disorders, recently received a five-year, $1.75 million grant to study neuroplasticity and mechanisms supporting language improvement in chronic aphasia, a speech-language disorder that frequently occurs following left-hemisphere stroke.

As Kurland explains, "Aphasia can affect any or all aspects of language including speaking and understanding spoken language, reading and/or writing. With brain injury from stroke, for example, people with aphasia know exactly what they want to say but they can’t access the words. In the end what we really want to do is increase the person’s functional independence, improve their language proficiency and maximize their quality of life."

In fact this work, which will focus on more severely aphasic individuals than typical studies, is innovative for its three-pronged approach using behavioral, neuro-imaging and quality-of-life measures to assess meaningful long-term improvements from intensive treatment plus a maintenance home therapy program.

Kurland and a full-time speech-language pathologist will conduct three one-year treatment experiments, enrolling eight different people per year who have chronic, moderate-to-severe aphasia. An important aspect of the study, supported by a National Institutes of Health grant, will be functional magnetic resonance imaging (fMRI) to characterize brain activity patterns that correlate with improved picture naming and to compare such patterns among treatment groups.

One of the key questions Kurland hopes to answer is which of two approaches, constraint-induced language therapy (CILT) or unconstrained language therapy (ULT), is most effective in helping people with aphasia to recover language skills and maintain them over time. In CILT, people are constrained to use only spoken words to communicate about pictured objects and actions during their therapy sessions. With ULT, they can use gestures, drawing, writing, pointing and facial expressions as well as speech.

Both therapies are expected to improve quality of life along with language skills, Kurland notes. But she expects the intense focus on speech in the CILT approach plus at-home practice to prove most effective and long-lasting. "We have anecdotal evidence that this type of training can improve such factors as confidence that can affect a person’s quality of life, but tools for measuring these changes are still being developed," she says.

"When a person has a stroke and aphasia, their social universe suddenly shrinks, they lose their job and the fulfillment of work and they have trouble communicating. Confidence can go way, way down. If we can offer improvement and boost their confidence to pick up the telephone or get out of the house and operate more independently, we’ll have succeeded."

Therapy for study participants, at no cost to them, will be intense, with daily three-hour sessions of speech and language treatment in the laboratory five days a week for two weeks using either CILT or ULT, followed by daily home practice sessions ("overlearning") and regular check-in sessions via video link.

Participants will undergo pre- and post-treatment diagnostic testing, including structural and functional MRI, and two post-treatment testing sessions at six months and one year after their therapy sessions. Kurland says she expects words that are trained and practiced, that is "overlearned" after CILT and ULT will show better maintenance in 12-month follow-up testing.

"The idea is to gradually improve one’s ability to verbally name an object or action that is pictured on a card. On the first day, it may be that a participant is unable to say ‘dog’ when shown a picture of a dog, but following the intensive practice retrieving first the word and then short phrases including the word, the connection between the concept and the word becomes more automatic."

In her experiments, the language researcher also looks for treatment-induced neuroplasticity, which is whether the brain’s structure and activities are changed by treatment as measured by analysis of the four fMRI tests per subject. A group of healthy, non-brain-damaged, age-matched subjects will serve as controls.

For information on eligibility to participate in this study, Kurland encourages persons with aphasia or their significant other to contact the Brain Research on Chronic Aphasia (BRoCA) lab at (413) 545-4008. The lab offers workshops for stroke survivors and family and a monthly support group. It also sponsors an annual Walk for Aphasia Awareness in downtown Amherst, held this year on April 14, 2012.

The aphasia research of Jacquie Kurland is featured in two new articles appearing in Health Care News and in the Springfield Republican. Kurland also recently appeared on WFCR. Follow the links to read more.

Reich teaches workshop at Thailand’s Ministry of Public Health

On March 1-2, Nicholas G. Reich, Research Assistant Professor of Biostatistics, co-instructed a workshop titled “Forecasting Dengue Incidence and Outbreaks in Thailand” in Bangkok, Thailand with colleagues from Johns Hopkins University, where Reich received his PhD. The Field Epidemiology Training Program at the Ministry of Public Health in Thailand hosted the workshop.

The Models of Infectious Disease Agent Study, or MIDAS, sponsored Reich’s involvement in the workshop. MIDAS, an international research consortium, was established by the National Institute of General Medical Sciences in 2004 as a “collaborative network of research scientists who use computational, statistical and mathematical models to understand infectious disease dynamics and thereby assist the nation to prepare for, detect and respond to infectious disease threats.” (For more information, visit their website at https://www.epimodels.org/.)

Reich and his colleagues designed the workshop to introduce new methodologies that help predict dengue incidence and provide early warning of outbreaks in Thailand. The researchers discussed two approaches to prediction and outbreak detection. The first focuses on using the frequency of Internet searches related to dengue to identify outbreaks before they are evident in case data reported to the Thai Ministry of Public Health. The second method uses spatial and temporal correlation of dengue incidence in different provinces throughout Thailand to estimate the probability of future outbreaks in each Thai province months into the future. Both methods are implemented in the open-source R software package, a free statistical analysis tool used by researchers worldwide. Reich and colleagues provided the participants with code for running the predictions and creating “weather-map” style risk maps of outbreaks in Thailand.

Reich and his collaborators have been working for several years with the Ministry to develop these methods and incorporate them into an easy-to-use software package. “We hatched this idea with our Thai collaborators a few years ago and have been putting the pieces together since then,” said Reich. “This was the first time that we showed them a version of the software. Many of the participants told us that they were excited about using it in their work to help them understand the current outbreak threats in Thailand. We think there is great potential for these methods to be used to inform public health response to infectious disease epidemics in Thailand.”

Graduates of the Thai Field Epidemiology Training Program, many of whom currently serve as epidemiologists for the Ministry throughout Thailand, were the primary participants in the workshop.

DiFulvio presents at the 2012 NASPA Conference

Gloria DiFulvio, undergraduate program director for the Public Health Sciences major, joined Diane Fedorchak and Sally Linowski of University Health Services (UHS) as featured presenters at the 2012 NASPA Alcohol and Other Drug Abuse Prevention and Intervention Conference, held January 19-21 in Atlanta.

Linda Downs-Bembury, Grants Manager for the School of Public Health and Health Sciences, recently received one of ten Chancellor’s Citation Awards for 2012. Chancellor Holub honored Downs-Bembury, along with the other Citation recipients and the Gerald F. Scanlon Student Employee of the Year award winners, at a reception held on May 2, 2012, in the Marriott Center.

“I was very surprised when I received the call that I’d won the award,” said Downs-Bembury. “I knew I’d been nominated, but I didn’t think there was any chance I’d receive it. I think I beamed for the next week.”

The Chancellor’s Citation Award program was implemented in 1985 as part of the university’s continuing effort to reward exemplary performance. The award recognizes and honors university staff members who have demonstrated outstanding performance in contributing their time and/or skills in helping the university achieve its goals and objectives. Specifically sought are examples of original contributions to the university, attainment of high-priority university objectives, performance “beyond the call of duty,” and achievement of significant improvements in productivity or savings in university operations.

“It’s particularly meaningful to receive this award,” Downs-Bembury added. “In terms of personal performance, I think this is the highest award you could receive. It meant a lot to me to be able to receive it under Chancellor Holub’s leadership.”

Recipients may be nominated by any member of the campus community. Richard Peltier, Assistant Professor of Environmental Health Sciences, championed Downs-Bembury for the award.

“I nominated Linda because she’s a wonderful co-worker who helped me immensely as a junior faculty member here,” Peltier commented in a video testimonial played at the award reception. “Linda’s primary responsibility to us as faculty is to accept our scientific research proposals that come in the form of scientific jargon and convert it into the language that’s necessary for the funders. Linda puts the burden of writing the science on me, and she takes all of the administrative hassle and takes it upon herself to help with that process. I wanted to thank Linda for all her hard effort and the wonderful work she does every day.”

“I was very, very touched by Rick’s video,” said Downs-Bembury. “It’s infrequent that people have the time to say thank you, and to have someone say thank you in such a public forum was really touching.”

“I’m still amazed,” she added. “I want it to happen again.”

Downs-Bembury has served as the SPHHS Grants Manager for the past 9 years. She has been a university employee for nearly 31 years.

Grant News

Choe awarded grant to study robot-mediated stroke rehabilitation

Yu-kyong Choe, Assistant Professor of Communication Disorders, has been awarded a two-year, $109,251 grant from the American Heart Association (AHA) to examine “Interdisciplinary Stroke Rehabilitation Delivered by a Humanoid Robot.”

Nearly three million Americans chronically experience the debilitating effects of stroke on their daily communication, dexterity, and mobility. Even at the chronic stage, stroke patients can make significant recoveries from these disabilities; however, intensive rehabilitation programs are rarely available or accessible for most stroke patients.

Choe’s research project will explore alternative methods of delivering needed therapy services. In collaboration with Roderic Grupen, Professor of Computer Science, Choe will utilize a humanoid robot to deliver both speech and physical therapy services to stroke patients.

The proposed study will compare two treatment conditions: robot-mediated and computer-mediated. In the robot-mediated condition, patients will complete word-retrieval tasks and upper-limb exercises delivered by a humanoid robot. In the computer-mediated condition, the same tasks and exercises will be presented on a laptop computer. Choe predicts that the robot-mediated condition will yield better outcomes in both speech and physical functions because of the interactive engagement and the resultant patient-robot interactions.

Choe’s research holds the potential for clinical research as well as clinical practice. The robot-mediated treatment program can deliver highly structured therapy activities, and it can ensure the consistency of tasks across therapy sessions and across treatment conditions. Choe envisions future projects utilizing the humanoid robot as a reliable research tool to further test various aspects of interdisciplinary stroke rehabilitation.

To learn more about Choe’s project or to participate in the study, please call her (413-545-4297) or e-mail her (ychoe@comdis.umass.edu).

Van Emmerik leads research team examining impact of soldier's equipment load

A team of researchers led by Richard Van Emmerik recently received a 2.5-year, $975,000 grant through the Navy Health Research Center in the Department of Defense to study how the average 100-lb. equipment load carried by soldiers, which can be even heavier in some missions, affects their survivability, likelihood of injury and ability to carry out missions.

"Load is not a new issue for field commanders to consider," says Van Emmerik, who is director of the Sensory-Motor Control Laboratory. "But while past studies typically focused on how load affects gait and the lower body, we will for the first time look at how the upper body, trunk and head coordinate in a soldier who is burdened by a heavy load, which is a fundamentally different and a more complex situation."

Doctoral candidate Christopher Palmer, an Army employee who is an expert in motor control and military performance and a key member of Van Emmerik's team, adds, "To us, gait is just the beginning. We'll introduce a visual search task and track the coordination of upper body, postural control and visual acuity. No study has yet added all these, plus other factors, together in a realistic way to look at how load affects the soldier's ability to perceive threats, his or her operational effectiveness and survivability in combat."

Findings will also have practical significance for firefighters, police, rescue workers and others who must wear helmets, body armor, backpacks or other equipment while carrying out their duties.

The Kinesiology research team, which includes doctoral students Mike Busa and Luis Rosado, with postdoctoral fellows Darnell Simon and Jongil Lim, will recruit highly trained infantrymen as laboratory subjects who will be tested with no load as well as while carrying a variety of loads between 70 and 120 lbs. for the studies.

Van Emmerik notes, "Biomechanics has taught us a lot over the past 30 years about load and locomotion, stamina, oxygen use, energy use and so on. We'll expand to look at whether load affects reaction time, visual attention to critical details and the ability to discriminate friend or foe. We'll set up some fairly realistic tasks such as having a soldier jump off the back of a truck, scan an area, and then immediately hit targets in a marksmanship test."

In preliminary tests, Palmer says, they have used participants who are "fresh" and not fatigued. But as work progresses, they plan to also conduct tests with women and with subjects who are tired to see if they have trouble recognizing friend or foe on a radio call or taking a marksmanship test wearing night vision goggles, for example. "We'll add different layers of stress in a smart progression so that we can understand what each layer is adding to the challenge."

Overall, the Kinesiology research team would like to be able to report to the military a great deal of new knowledge about the physical and mental trade-offs and limitations that come with soldiers carrying heavy loads, and of which a field commander can be aware.

"We'd like to contribute to commanders being able to make better decisions about what can be accomplished under certain conditions," Van Emmerik says. "For example, if the protective equipment has to be x, y and z, where can you expect the sharp drop in performance and how can you balance that with mission success?"

Reich receives UMass Amherst Open Education Initiative Grant

Nicholas Reich, Research Assistant Professor of Biostatistics, was recently selected as a recipient of an Open Education Initiative Grant by the University of Massachusetts Amherst. The grant comes as part of a joint incentive program by the Provost’s Office and the University Libraries to encourage faculty to use existing technology and information resources to support student learning.

The high cost of commercial print textbooks is a growing concern for students and their families. The Open Education Initiative provides grants based on competitive proposals designed to support faculty to use non-traditional educational resources as an alternative to the traditional textbook.

Reich received a $1000 grant for his proposal to develop a statistical computing course that will utilize freely available resources for statistical learning, such as the popular software program R. He will deploy this alternative curricular resource strategy for his Introduction to Statistical Computing and Data Visualization course to be taught during the Fall 2012 semester.

Kinesiology doctoral students LaBarbera, Xin receive ACSM Foundation Research Grants

From left: Ling Xin and Kate LaBarbera

Kate LaBarbera and Ling Xin, Kinesiology doctoral students, have been awarded research grants from the American College of Sports Medicine (ACSM) Foundation. The ACSM Foundation awards research grants for doctoral students up to $5,000 for a one-year period. The awards are to be used for experimental subjects, supplies, and small equipment needs.

The ACSM Foundation Doctoral Student Research Grant program awarded LaBarbera for a proposal titled “NF-κB and muscle damage effects on endothelial cells.” LaBarbera hopes to gain a better understanding of the cellular and molecular mechanisms of muscle repair and regeneration. In order to do this, her study will focus not only on muscle cells, but also on the cells that contribute to the skeletal muscle environment, including pericytes and endothelial cells. Pericytes are a type of cell that associates with endothelial cells, which form capillary vessels. The aim of her project is to determine how pericyte NF-κB, a transcription factor that regulates many cellular processes including proliferation and muscle damage stimulus, affects endothelial cell proliferation in vitro. She also hopes to identify the cytokines involved in the signaling process between pericytes and endothelial cells. This would identify for the first time that endothelial cells are important for muscle regeneration.

Xin received her award for a proposal titled “Attenuated inflammation: contralateral repeated bout effect.” Her research examines the phenomenon of “repeated bout effect” (RBE), in which a second strenuous exercise session causes less damage to the same muscle used in the initial session. Her previous research has shown that RBE also occurs in the opposite (contralateral) leg. The mechanisms to explain this finding are not known. Her project will examine if the contralateral RBE is due to a blunted inflammatory response involving nuclear factor-kappa B (NF-κB), which is believed to be an important stimulator of inflammation after damaging exercise. The identified molecular and cellular mechanisms involving NF-κB from this project may be important in the development of interventions to enhance contralateral RBE while setting up rehabilitation exercise for a unilaterally immobilized limb and in identifying targets of future therapies to facilitate recovery from injury.

The ACSM began its Foundation Research Grant Program in 1989. In 2011, the program awarded approximately $111,000 among 19 research students.

Foulkes' research could improve testing, resource use for treating AIDS in poorer countries.

One of the major problems that has slowed progress toward universal access to life-saving antiretroviral therapy (ART) to treat AIDS in developing nations has been limited availability of laboratories and trained medical staff to conduct blood tests of immune system CD-4 T-cell levels that indicate when to start ART.

Now, Andrea Foulkes, Associate Professor of Biostatistics at the University of Massachusetts Amherst School of Public Health and Health Sciences, with colleagues at Philadelphia’s Wistar Institute and elsewhere, propose a tool for prioritizing laboratory-based CD-4 cell count testing by linking cell counts to other patient data. They report details of their new “prediction-based classification” (PBC) system in the current issue of PLoS Medicine. Researchers in the United States, Argentina, South Africa, Canada, the U.K. and Malaysia took part in the study at seven sites around the world.

Foulkes, who with others at UMass Amherst has been actively driving this research, says, “By using these new statistical tools, we can decide how to allocate resources to the patients who need them the most. In other words, we identify which patients are most likely to benefit from secondary testing.” PBC could reduce by nearly 57 percent the number of CD-4 tests needed during the first year of ART.

The study is a retrospective analysis that modeled CD-4 counts from 1,000 HIV-infected individuals. The researchers used estimates derived from the model to predict, from CD-4 counts taken at the start of treatment plus white blood cell counts and lymphocyte percentage measurements taken later, whether CD-4 counts would be above the threshold recommended for starting ART and how a patient would do over time.

Dr. Luis Montaner at the Wistar Institute says, “Our algorithm could be used as a triage tool to direct available laboratory CD-4 testing capacity to high-priority individuals, that is, those likely to experience a dangerously low CD-4 count.” He and colleagues believe that with additional testing and refinement, their PBC system could increase the ability of medical and laboratory facilities in poorer countries to maintain AIDS treatment.

“Our data raises the possibility that we could save money in order to save more lives,” Montaner points out. Foulkes, Montaner and colleagues say that more studies are needed to demonstrate the long-term feasibility, clinical effectiveness and cost-effectiveness of the PBC approach and whether the accuracy of its predictions can be improved.

The work was supported by the National Institutes of Health, The Philadelphia Foundation and The Wistar Institute.

Bertone-Johnson writes invited commentary for the Archives of Internal Medicine

Elizabeth Bertone-Johnson, Associate Professor of Epidemiology, has co-written an invited commentary for the journal Archives of Internal Medicine.

In the commentary, Bertone-Johnson and co-author JoAnn Manson discuss a new study by Italian researchers suggesting that a single ultra-high dose of vitamin D may help women with painful menstrual periods and allow them to forgo the use of painkillers. Bertone-Johnson and Manson recommend larger trials with a longer follow-up to confirm the benefits and weigh them against the potential long-term risks associated with such high doses.

The new study, along with Bertone-Johnson and Manson's commentary, are receiving additional press coverage at CBS News and MedPage Today. To read their commentary, click here.
