Margulies Among Recipients of Award to Study Concussions

How can physicians and engineers help design athletic equipment and diagnostic tools to better protect teenaged athletes from concussions? A unique group of researchers with neuroscience, bioengineering and clinical expertise are teaming up to translate preclinical research and human studies into better diagnostic tools for the clinic and the sidelines as well as creating the foundation for better headgear and other protective equipment.

The study will be led by three coinvestigators: Susan Margulies, the Robert D. Bent Professor of Bioengineering at the University of Pennsylvania’s School of Engineering and Applied Science (right); Kristy Arbogast, co-scientific director of the Center for Injury Research and Prevention at the Children’s Hospital of Philadelphia; and Christina Master, a primary care sports medicine specialist and concussion researcher at CHOP. They will use a new $4.5 million award from the National Institute of Neurological Disorders and Stroke.

The five-year project focuses specifically on developing a suite of quantitative assessment tools to enhance accuracy of sports-related concussion diagnoses, with a focus on objective metrics of activity, balance, neurosensory processing, including eye tracking, and measures of cerebral blood flow. These could also provide prognoses of the time-to-recovery and safe return-to-play for youth athletes. Researchers will examine such factors such as repeated exposures and direction of head motion. In addition, they will also look at sex-specific data to see how prevention and diagnosis strategies need to be tailored for males and females.

The multidisciplinary research team believes this study will result in post-concussion metrics that can provide objective benchmarks for diagnosis, a preliminary understanding of the effect of sub-concussive hits, the magnitude and direction of head motion and sex on symptom time course, as well as markers in the bloodstream that relate to functional outcomes.

Knowing the biomechanical exposure and injury thresholds experienced by different player positions can help sports organizations tailor prevention strategies and companies to create protective equipment design for specific sports and even specific positions.

The study will enroll research participants from The Shipley School, a co-ed independent school in suburban Philadelphias, and from CHOP’s Concussion Care for Kids: Minds Matter program which annually sees more than 2,500 patients with concussion in the Greater Delaware Valley region.

The study is funded by the National Institutes of Health.

Selected from a large national pool of applicants, the Allen Foundation grant will bring together new technology platforms developed by Drs. Huh and Issadore to study how concussions occur at the microtissue scale and release markers of rewiring  during recovery. Network theory models from Dr. Bassett’s group will provide an entirely new view on how concussion recovery occurs at all scales in the brain. The overall impact of the project will be to move away from the widely held perspective that all concussions should be treated identically and towards a view that concussions can follow several recovery pathways, some of which must be monitored closely in the days to weeks following injury.

Pressure Sores Targeted by Flysole

Among the myriad medical complications caused by diabetes, pressure sores of the feet are among the most troubling. Because of the common  complication of peripheral neuropathy, people with diabetes are often unable to determine how much pressure is being exerted on their feet. As a result, they cause foot ulcers, which can become infected, leading in the worst cases to amputation.

The Flysole combines an insole with five sensors (top) and an ankle band (bottom) to house the electrical components, including the circuit for the pressure sensors as well as the microcontroller and SD card to log the pressure data.

One of the senior design teams from the Department of Bioengineering at the University of Pennsylvania developed a project to address this problem. Their solution was Flysole (right), a prognostic implant that diabetic patients can wear to collect data on foot pressure so that the doctor can prescribe an optimal orthotic to prevent sores from developing. The team was named one of the three winners of this year’s competition.

The team, which consisted of Parag Bapna, Karthik Ramesh, Jane Shmushkis, and Amey Vrudhula, designed the Flysole as a lightweight insole with ankle band paired with software that generates a profile of the pressure on the sole of the patient’s foot. The insole has five sensors to collect these data. The cost is approximately $75 per pair.

In addition, the team made the Flysole to be reusable by including a polyurethane laminate sleeve for the individual patient. Future improvements envisioned by the students include improving the software to include recommendations for orthotics and alternate arrangements for the sole sensors.

Students in the BE Department have received several awards

Every year the Penn Bioengineering Department presents several awards to students. In addition to the Senior Design Awards, which will be featured over the course of the month, students were awarded for their service, originality, leadership, and scholarship.

The Hugo Otto Wolf Memorial Prize, endowed more than a century ago by the Philadelphia architect Otto Wolf, in memory of his son, was given to Margaret Nolan and Ingrid Lan. The Herman P. Schwan Award, named for a former faculty member in Bioengineering, was given to Elizabeth Kobe and Lucy Chai.

The Albert Giandomenico Award, presented to four students who “reflect several traits that include teamwork, leadership, creativity, and knowledge applied to discovery-based learning in the laboratory,” was given to Justin Averback, Jake Budlow, Justin Morena, and Young Shin.

In addition, Sushmitha Yarrabothula received the Bioengineering Student Leadership Award and four students — Hayley Williamson, Amey Vrudhula, Jane Shmushkis, and Ikshita Singh, won the Penn Engineering Exceptional Service Award.

Finally, the Biomedical Applied Science Senior Project Award, presented annually to the students who have “best demonstrated originality and creativity in the integration of knowledge,” was awarded to Derek Yee and Andrea Simi.

“These awards recognize many aspects of our students: their high academic achievement,  exceptional collaborative spirit, and leadership abilities,” said BE department chair David Meaney. “However, these traits are not limited to the only these students. Every single one of our undergraduates at Penn pushes themselves well beyond the classroom and into the community to make a unique difference.”

Ivan Kuznetsov
, a dual-degree MD/PhD program in the Penn Department of Bioengineering, has received a prestigious Paul & Daisy Soros Fellowship for New Americans. A first-generation American born in Ohio, Ivan is the son of parents who immigrated from Russia. He earned a BS in Biomedical Engineering at Johns Hopkins University before enrolling at Penn last year.

Professor Brian Chow, PhD, who directs the lab in which Ivan works, speaks glowingly of him. “Ivan’s research in the design of de novo proteins for molecular imaging represents a fundamentally new approach to inventing tools for elucidating the physiology of targeted cells. It is completely unchartered territory for mammalian biology and bioengineering,”  Dr. Chow says. “What sets Ivan apart as a young scientist is his rare blend of exceptional skills in experimental biology and deep understanding of its mathematical and physical underpinnings. Few possess that blend at his age.”

Every year, the Soros Fellowships are awarded to 30 American students who are either immigrants or the children of immigrants. The field is highly competitive; this year there were almost 1,800 applicants. Ivan and his 29 colleagues will receive up to $90,000 for funding of their graduate educations.
