In many ways, it was a perfect storm. Pariveda Solutions, a Dallas-based management consulting firm that specialized in helping its client maximize performance, reached out to the Houston Food Bank about offering some of its interns for a project. The Food Bank, long a pioneer and foot soldier in the fight to end food insecurity and hunger for the region's residents, had been considering ways to harness technology to better serve the needs of its clients.

"It was a fantastic opportunity for us," says Casey Ferrell, the Houston Food Bank's director of information technology, about the opportunity. "And we thought an app would be the best thing for the intern team to work on."

Five Pariveda interns worked over the summer on the app, which taps into Amazon Web Services, which the Food Bank was already using.

"Since the Houston Food Bank was already using AWS, this fit into where they wanted to go," explains Kevin Moorman, principal consultant for Pariveda. "The app uses GPS location services to help connect people who need the Food Bank's services with the closest location that can help them."

Across the Houston region, more than one million people are food insecure, lacking reliable access to nutritious food. Through its network of more than 1,500 community partners, the Houston Food Bank leads the fight against hunger by providing food assistance across its 18-county coverage area in southeast Texas. The Food Bank partners with thousands of entities, from soup kitchen to meal sites to shelters. Every year, the Houston Food Bank helps feed 800,000 individuals. There is a lot of need, and there are a lot of sites around the region that can aid people lacking food.

The app, in addition to pinpointing locations that can provide food for those in need, also allows people to make appointment with Food Bank staff. Currently, those appointments are on a walk-in basis, and clients are seen on a first-come, first served basis. With the launch of the app earlier this month, Ferrell says the organization has launched a pilot program with its Portwall location to allow clients to make appointments via the app. In the future, they should be able to make appointments all more Houston Food Bank locations.

"We actually did a soft launch back in October, says Ferrell. "And now, we have more than 3,000 downloads and 2,500 monthly users. The app lets them see open times for appointments, as well as contact information for locations."

Ferrell says the feedback from users has been positive. In particular, they enjoy the ability to receive updates about their appointments. But the app also provides for a greater user experience, allowing clients the chance to set things up as it makes sense for them and their daily schedules.

"We've also heard from other food banks who are looking to do something similar," says Ferrell. "So, we're looking forward to sharing our experiences with them."

Pariveda Solutions' 11-week internship program, offered each summer, is focused on making an impact to the community. The app last summer's intern cohort created is a first because it integrates with the database housed on AWS and reaches new communities.

"Working with Houston Food Bank gave us the opportunity to impact the Houston community at a large scale," says Allison Esenkova, Houston vice president for Pariveda Solutions in a press release announcing the app. "It provided a platform for our interns to learn the world of consulting while giving back in a way that impacts the Houston community to reduce hunger."

The internship was also an important opportunity for students to get hands-on experience not only in building an app, but also to get experience working with a client, listening to feedback and coming up with solutions to challenges.

"We want our interns to have as much real-world experience as possible," says Moormann. "This not only provided that, but has wonderful value for the end user. The app makes the process of finding services much smoother for those who need them."

Ferrell says that as the app is updated, the Houston Food Bank hopes to be able to use it to engage volunteers, as well as provide places where clients can rate their experiences at various food pantries.

"This has been a great value to us," says Ferrell. "And it allows us to provide better services to our clients."


The app connects the user to the Houston Food Bank and also provides more information about resources.

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.

Houston doctor wins NIH grant to test virtual reality for ICU delirium

Virtual healing

Think of it like a reverse version of The Matrix. A person wakes up in a hospital bed and gets plugged into a virtual reality game world in order to heal.

While it may sound far-fetched, Dr. Hina Faisal, a Houston Methodist critical care specialist in the Department of Surgery, was recently awarded a $242,000 grant from the National Institute of Health to test the effects of VR games on patients coming out of major surgery in the intensive care unit (ICU).

The five-year study will focus on older patients using mental stimulation techniques to reduce incidences of delirium. The award comes courtesy of the National Institute on Aging K76 Paul B. Beeson Emerging Leaders Career Development Award in Aging.

“As the population of older adults continues to grow, the need for effective, scalable interventions to prevent postoperative complications like delirium is more important than ever,” Faisal said in a news release.

ICU delirium is a serious condition that can lead to major complications and even death. Roughly 87 percent of patients who undergo major surgery involving intubation will experience some form of delirium coming out of anesthesia. Causes can range from infection to drug reactions. While many cases are mild, prolonged ICU delirium may prevent a patient from following medical advice or even cause them to hurt themselves.

Using VR games to treat delirium is a rapidly emerging and exciting branch of medicine. Studies show that VR games can help promote mental activity, memory and cognitive function. However, the full benefits are currently unknown as studies have been hampered by small patient populations.

Faisal believes that half of all ICU delirium cases are preventable through VR treatment. Currently, a general lack of knowledge and resources has been holding back the advancement of the treatment.

Hopefully, the work of Faisal in one of the busiest medical cities in the world can alleviate that problem as she spends the next half-decade plugging patients into games to aid in their healing.
