When people ask ��AV Associate Professor David Lattanzi why a civil engineer is working in forensic nursing science, he can only say, ‘Why not?’ Lattanzi is a co-principal investigator on research to develop a tool that will help clinicians and others assess bruises on victims of violence, particularly those with darker skin tones.

This work, led by principal investigator Katherine Scafide, associate professor in the College of Public Health, recently received a $4.86 million gift from an anonymous donor which extends the findings of an earlier Department of Justice grant that began more than three years ago.

The team’s multidisciplinary research combines Scafide’s work with alternate light source technology, co-PI Janusz Wojtusiak’s expertise in informatics, and Lattanzi’s knowledge of computer vision and deep learning to address challenges of identifying bruises and other injuries in victims of domestic violence.

“When I started at Mason 10 years ago, I never imagined that my work could have a societal impact like this,” said Lattanzi. But Lattanzi has always been interested in finding innovative solutions to real-world problems. A structural engineer by training, he spent his early years as a bridge and tunnel inspector. After seeing too many close calls while working on inspection sites, he thought there must be a better way. So he began using drones and imaging to address the next generation of infrastructure-inspection technologies—and make bridge inspection less dangerous.

Though drones aren’t part of this research, he and the team are using the image-based diagnostic techniques that began a decade ago. Now Lattanzi is enhancing these tools with artificial intelligence (AI) and machine learning to examine human skin structures damaged by incidents of domestic violence.

According to a statement from the university, one in three women worldwide experience some form of violence. In the United States, more than 10 million women and men deal with interpersonal violence each year. These numbers tell only part of the story, because bruises are difficult to detect on darker skin tones, many victims miss out on getting the help they need.

The tool these researchers will build needs a large enough database to identify skin tones “accurately and equitably,” said Lattanzi. One of the important goals of the project, therefore, is to build a unique data repository that combines images of bruises and other injuries, with measurements, clinical and demographic information about the victim, and information inferred by artificial intelligence. Currently, the platform includes about 30,000 images of bruises collected using visible and alternative light sources.

“Having a massive database leads to better outcomes and measurably better outcomes for those victims downstream in terms of their care and in terms of their outcomes in the criminal justice system,” Lattanzi said.

The tool the Mason researchers are building could be an app on a smartphone that clinicians can use to assess the age of bruises. Lattanzi said they hope to have a prototype in a year, and possibly have the technology available for use in a couple of years.

Clinical Training Meets Virtual Reality John Brandon C… Wed, 04/20/2022 - 10:29

Graduate student Sindhu Mallala studies health informatics at Mason to gain a deeper understanding of how technology can transform all aspects of health care.

For Sindhu Mallala, serving as a physician in her home country of India is an honor. She learned about the essential role physicians have in health care while studying at the Dr. NTR University of Health Sciences in Andhra Pradesh, India. When she began practicing medicine, she realized the impact she could make by incorporating her dedication to helping others with her love of science and technology to resolve issues that health systems in India were experiencing.

"While working, I saw the amount of data we collected in a hospital [that] just sat in piles, as the concept of digital records is still not as established back home," said Mallala. "I looked up ways to make sense of it, like pieces of a puzzle to solve both medical and hospital issues; Health informatics was the answer to my question."

Mallala's mission to study health informatics fueled her move to America to gain a deeper understanding of how technology can transform the way health systems operate, especially in storing, managing, and accessing critical patient data more quickly and securely.

"The health informatics program at Mason is well-tailored,” Mallala said when asked why she chose Mason for graduate school. “I wanted to learn from the best, so I could go back home and use this in a way that helps everyone in my community."

While at Mason, Mallala pursued opportunities that gave her insight into just how impactful technology can be—not just for hospital operations but also for training the next generation of health care providers.

"Now that I have been on both sides of the spectrum, IT and as a health care provider, I have a better understanding of how to bridge the gaps in between,” Mallala said.

Discovering New Opportunities at the Virtual Reality Simulation Lab

Mallala teaching Mason President Dr. Gregory Washington how to use the virtual reality technology.

Mallala soon became a graduate teaching assistant at the College’s Virtual Reality Simulation Lab, an opportunity that allowed her to have a direct role in discovering how technology can reshape the future of health care. The Lab provides students in various health majors with interdisciplinary opportunities to practice the skills they learn in class through virtual real-world scenarios. For Mallala, this was a chance to incorporate her clinical background with her newfound knowledge of health informatics.

"The Virtual Reality Lab encourages critical thinking and provides a safe space to practice and make mistakes," said Mallala. "Improving technical and patient communication skills are two primary goals of our Lab. We practice evidence-based medicine, and most of the cases that we practice are with diagnoses that students might come across during their [training]."

Having the opportunity to help prepare future health care professionals through virtual reality technology has developed Mallala's perspective on the possible ways technology can enhance health care delivery and training. With her education in health informatics and experience as a physician, she selects appropriate cases for students to explore in virtual reality that align with their course requirements. She also assists Bethany Cieslowski, VR and simulation coordinator in the School of Nursing, in setting up the lab and debriefing with students about the cases they completed.

Until Mason, Mallala said that she did not consider virtual reality simulation as a way to train medical professionals.

"I find the concept of learning skills and practicing patient case management in a lab to be quite intriguing,” she said. “The Lab serves as an opportunity [to prepare students] to handle cases in an informed and methodical way. I've gained a great deal of knowledge from this interprofessional association of informatics and nursing. My perspective on education has shifted significantly as a result of the Virtual Reality Lab. I personally learned a great deal from Dr. Bethany Cieslowski, my mentor, about how to engage students and encourage participation."

In her pursuit to strengthen herself as a physician by obtaining a master's degree in health informatics, Mallala values the many opportunities she receives at Mason that have aided her along her journey in health care. Now, she looks to the future for ways she can further health and technology research by applying her clinical knowledge with her newfound technological skills.

"Now that I have been on both sides of the spectrum, IT and as a health care provider, I have a better understanding of how to bridge the gaps in between,” Mallala said.

Introducing the Innovate for Good Series

Introducing the Innovate for Good Series John Brandon C… Fri, 02/04/2022 - 08:52

Innovate for Good is a new ongoing series that examines how faculty in the College of Health and Human Services are improving health outcomes using technology such as artificial intelligence, virtual reality, and personal apps.

Part I: Reducing Caregiver Stress & Improving Recovery Cues

By its very nature, the practice of social work involves people. After all, the definition of social work is, essentially, people helping people. But in an era of artificial intelligence, virtual reality, and machine learning, technology is playing an increasingly central role in how people help people.

In ��AV’s College of Health and Human Services, faculty members from the Department of Social Work are embracing technological innovation in its many forms to advance the practice of social work.

“In the field of social work, our goal has always been to figure out how to help those in our communities, whether through practice, organizational leadership, or policymaking,” said Emily S. Ihara, chair of the Department of Social Work. “What’s new is that we’re looking at fresh ways to gather more data to assess how we can best and most efficiently create social change.”

Innovate for Good begins with two ways researchers are using apps and virtual reality to improve the lives and health of those they work with.

Managing and Minimizing Caregiver Stress with a Phone

Caregiver burnout? There’s an app for that.

Funded by a Virginia Center on Aging, Alzheimer’s & Related Diseases Research Award Fund (ARDRAF) grant of $45,000, Ihara and Cathy Tompkins, professor of Social Work, are working with developers Ram Balasubramanian and Atreya Chaganty to help those who provide care for people living with dementia.

They are evaluating use of an app called Zelar developed by health care company Mantrah. This app will be geared toward caregivers with the intent of helping them manage the care of both the dementia patients they help and themselves.

“Care partners are often overwhelmed,” said Ihara. “The idea is that caregivers will enter information about different aspects of the care plan and they will be given reminders and helpful tips to provide organization.”

The app will have several features, including care plan creation, the ability for collaboration with other caregivers, plus self-care plans, a journaling option, and insights that provide feedback to caregivers on their reported performance.

“We’re trying to see if we can use technology to reduce caregiver stress,” said Ihara.

The project, Managing Mental Health Through Technology: Examining the Effects of Collaborative Care Management Technology Application, is being developed with Mantrah.

“In the field of social work, our goal has always been to figure out how to help those in our communities, whether through practice, organizational leadership, or policymaking. What’s new is that we’re looking at fresh ways to gather more data to assess how we can best and most efficiently create social change.”

Harnessing the Power of Recovery Cues with Virtual Reality

A multidisciplinary team of researchers, working across four colleges and centers at Mason, is using technology to develop customized, real-time recovery supports to prevent drug relapse.

The research team is made up of Holly Matto in the Department of Social Work, along with Padmanabhan Seshaiyer in Mason’s College of Science, Stephanie Carmack in Mason’s Center for Adaptive Systems of Brain-Body Interactions, Nathalia Peixoto in Mason’s Volgenau School of Engineering, Siddharth Bhattacharya in Mason’s School of Business, plus graduate students in engineering Vinicius Zanini and Bryce Dunn and in social work Cate Feldkamp, as well as Rudra Nagalia, a Mason intern and student at the Birla Institute of Technology and Science, in Pilani, India.

The team hypothesizes that they can disrupt the drug trigger-craving-relapse cycle by reorienting people to what is personally rewarding in their lives and regulating the brain and body’s response to drug triggers. These are known as recovery cues.

This idea was inspired by Matto’s work in the field of addiction and from the lived experiences of people in recovery. After treatment, individuals often go back to the same environments that trigger a desire to use drugs, resulting in a need for ongoing, consistent support.

“Because craving can still be quite intense even after months of abstinence, real-time interventions to support recovery are essential to preventing relapse long-term,” said Matto. Examples of recovery cues include music, soundscapes, inspirational quotes, and more.

The Mason team and its industry partner, Brightline Interactive, are examining the effects of recovery cues using virtual reality simulations. The work is being supported by a grant from the National Institutes of Health’s National Institute on Drug Abuse through a Small Business Technology Transfer (STTR) Grant.

“Rather than focusing on drug triggers, our team believes that by focusing on the rewarding parts of their lives, their recovery cues and supports, individuals in recovery can strengthen and grow,” said Matto.

Virtual reality is unique among other technological enhancements in that it can recreate some elements of the social situations and physical environments that typically trigger relapse, allowing patients to practice skills they will need when they encounter such situations in real life.

Along with investigating recovery cues using virtual reality, the team is developing their Recovery Engaged Mind (REMind-h) app. In this app, individuals in recovery will be able to upload their customized recovery cues according to their preferred sensory modality (visual, auditory, tactile) and content category (people, places, objects), and be able to access these cues when experiencing intense craving.

Innovate for Good is an ongoing series that examines how Mason faculty in the College of Health and Human Services are harnessing technology to improve health outcomes.

Jeffrey Moran

A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.

Jeff Moran, an assistant professor of mechanical engineering in the Volgenau School of Engineering, and colleagues from the University of Washington in Seattle studied self-propelled half-platinum/half-gold rods that “swim” in water using hydrogen peroxide as a fuel. The more peroxide there is, the faster the swimming; without peroxide in pure water, the rods don’t swim.

In this work, they set out to understand what happens when these artificial microswimmers are placed in a fluid reservoir containing a gradient of hydrogen peroxide––lots of peroxide on one side, not much on the other side.

They found that, predictably, the microswimmers swam faster in regions with high peroxide concentration, says Moran, whose research was published in the new issue of Scientific Reports.

As others had observed, the direction of swimming varied randomly in time as the swimmers explored their surroundings. In contrast, in the low-concentration regions, the rods slowed down and accumulated in these regions over the course of a few minutes.

The results suggest a simple strategy to make microswimmers passively accumulate in specific regions, an idea that might have useful, practical applications, he says.

Swimming at the microscopic scale is a ubiquitous phenomenon in biology, Moran says. “Lots of cells and microorganisms, such as bacteria, can autonomously swim toward higher or lower concentrations of chemicals that benefit or harm the cell, respectively.”

This behavior is called chemotaxis, and it’s both common and important, he says. “For example, your immune cells use chemotaxis to detect and swim toward sites of injury, so they can initiate tissue repair.”

Moran and colleagues, like others in the field, have long been curious whether artificial microswimmers can mimic cells by performing chemotaxis, continuously swimming toward higher chemical concentrations. Some had claimed that the platinum/gold rods, in particular, could swim autonomously toward peroxide-rich regions.

“We were skeptical of these claims since the rods aren’t alive, and therefore they don’t have the sensing and response capabilities that are necessary for cells to execute this behavior,” he says.

“Instead, we found the opposite: the rods built up in the lower concentration regions. This is the opposite of what one would expect from chemotaxis,” Moran says.

The researchers conducted computer simulations that predicted this and validated them with experiments, he says.

“We propose a simple explanation for this behavior: Wherever they are, the rods move in randomly varying directions, exploring their surroundings. When they get to a low-fuel region, they can’t explore as vigorously. In a sense, they get trapped in their comfort zones,” Moran says.

“Conversely, in the high-peroxide regions, they move at higher speeds and, because their direction is constantly changing, escape from these regions more often. Over time, the net result is that rods accumulate in low-concentration regions,” he says. “They don’t have any intelligence. They end up where their mobility is the lowest.”

Moran says this research is promising from a technical standpoint because it suggests a new strategy to make chemicals accumulate in a highly acidic area.

“Due to their abnormal metabolic processes, cancer cells cause their immediate surroundings to become acidic. These are the cells that need the most drugs because the acidic environment is known to promote metastasis and confer resistance to drugs. Thus, the cells in these regions are a major target of many cancer therapies.”

Moran and colleagues are now designing microswimmers that move slowly in acidic regions and fast in neutral or basic regions. Through the mechanism they discovered here, they hypothesize that acid-dependent swimmers will accumulate and release their cargo preferentially where their speeds are minimized, namely the most acidic and hypoxic regions of the tumor, where the most problematic cells reside.

There is much more research to be conducted, but “these rods may have the ability to deliver chemotherapy drugs to the cancer cells that need them the most,” Moran says.

“To be clear, our study doesn’t prove that chemotaxis is impossible in artificial microswimmers, period; just that these particular microswimmers don’t undergo chemotaxis.

“Instead, we’ve identified an elegantly simple method of causing unguided microswimmers to accumulate and deliver drugs to the most problematic cancer cells, which could have implications for the treatment of many cancers, as well as other diseases like fibrosis. We’re excited to see where this goes.”

Bioengineering professor Siddhartha Sikdar is using technology to help individuals with limb loss better control their prostheses.

His team is investigating a new way to operate prostheses using ultrasound waves to sense muscle activity.

“Our goal is to help amputees go about their daily lives with improved function,” says Siddhartha Sikdar, who is director of the Center for Adaptive Systems of Brain-Body Interactions (CASBBI).

Approximately 50,000 individuals are living with upper limb loss in the United States. A large proportion (35 to 45 percent) of people with upper extremity amputations discontinue the use of their prosthesis, mainly due to limited functionality and usability, Sikdar said, and there is a significant unmet need to develop better technological solutions to improve function.

His research group was recently awarded a Bioengineering Research Partnership grant from the National Institutes of Health to develop this technology for commercial use and perform clinical trials.

They are collaborating with the Walter Reed National Military Medical Center to test this technology in a military population using another new grant from the Department of Defense. They also have a grant from the Commonwealth Research Commercialization Fund to explore prosthetic training applications using a wearable ultrasound system.

The team is completing additional preliminary studies in amputee subjects using a benchtop system. In the meantime, they are in the process of miniaturizing the ultrasound instrumentation to incorporate it inside a prosthetic socket and developing and testing embedded algorithms for interpreting the ultrasound signals for controlling the prosthetic hands.

The next steps are to perform laboratory tests of an integrated system with people with amputations and perform safety evaluations in preparation for seeking FDA approval.

The successful completion of this research will lead to the first human evaluation of an integrated prototype that uses low-power portable imaging sensors and real-time image analysis to sense residual muscle activity for prosthetic control, he says.

“In the long term, we anticipate that the improvements in functionality and intuitiveness of control will increase acceptance by amputees,” Sikdar says.

Biography

Jeffrey Moran's research interests lie in understanding and using micro-scale thermal-fluid transport phenomena to enable new solutions to fundamental challenges facing humanity, including sustainable energy, environmental remediation, and cancer treatment. His doctoral work helped explain the physical mechanism for the self-propulsion of "catalytic micromotors," which are micrometer-size metallic rods (50 times smaller than the width of a human hair) that can "swim" and carry cargo through liquids. These rods are one subclass of "active colloids," microscopic self-propelled particles, that show promise for such applications as enhanced oil recovery, manufacturing of micro- and nanometer-scale structures, and even targeted drug delivery in the human body.

Moran received several awards, including the Young Researcher Award from the International Workshop on Micro/Nanomachines, the Shapiro Postdoctoral Fellowship Award from MIT, and a Graduate Research Fellowship from the National Science Foundation.

Outside of research, he is committed to science and engineering education in and out of the classroom. He has given workshops at local science museums and lectured (at both the general and technical levels) to university and high school students throughout the US and internationally.
