Seven local high schoolers took lessons from their own schooling challenges in 2020 to launch a free, virtual tutoring program last month with the goal of helping younger students close learning gaps of their own during this unprecedented academic year ahead.

Dubbed Teaching To Give, the project matches kindergarten through eighth grade students with honor roll high schoolers from Kinder High School for the Performing and Visual Arts, Strake Jesuit, and Bellaire High School for 30- to 45-minute teaching sessions in core subjects, languages, debate, and arts via Zoom.

Kinder HSPVA sophomore Weillison Hsu, who now serves as president of Teaching to Give, first proposed the idea to fellow piano major and Vice President Hayden Miller at the end of the 2019-20 school year. The 15-year-olds are bright, talented, and artistic, but their freshman years had not come without challenges: First, several of their teachers were required to take a leave of absence, leaving them with long-term substitutes. Then COVID-19 hit, making traditional learning impossible.

It took time to adjust, Miller says, but eventually he and his peers found their stride in the tech-based schooling style that Houston Independent School District has been following for months. Still, they feared the transition for younger students had not been as smooth.

"We have been used to that independence, where in elementary school, and middle school even, you do a lot hands on and in person," Miller says. So, they decided to help in a way that was safe, affordable, and approachable.

"During these times, it's just not possible to make sure that everyone is fully striving," Miller says. "We wanted to make it as easy as possible for parents to use us and to have a stress-free environment, to provide a successful education and set up."

Today, Teaching to Give has held more than 100 free web-based tutoring sessions for kids around the city in subjects from science to piano. They ask on-boarding students to complete a personality and learning style questionnaire and place them with one of their 29 tutors who they predict will work best with for their subject matter and interests. Miller says the minor age difference has allowed their sessions to have real impact.

"It provides a more relatable experience," he says. "A lot of the time we'll have the same interests as our students. We can use that to foster mutual excitement for the subject material."

Still, the group is learning how to teach in a virtual setting as they go.

"It really forces you to think of how you say things to get the result that you want," Miller says. "I think we will all come out of this as better communicators."

Miller, Hsu, and the five other board members — Lina Wu, Amy Park, Fiona Condron, Rushil Chetty, and Ashley Chu — plan to continue to focus on virtual tutoring sessions even after the pandemic ends and limitations on in-person learning lift. Again pulling from their own experience, they know that virtual options can provide big benefits for busy parents and students like themselves.

And in the meantime, they're hoping to start partnerships with a few local lower schools, are accepting applications for additional tutors, and are raising awareness for their new initiative, Project Pencil, which will donate art supplies to the Gregory-Lincoln Education Center in the Fourth Ward.

"Art is something that is universal. It takes away the stress of learning. Also, art lessons and music lessons are very expensive," Miller adds. "We wanted to incorporate that into our classes because that's what our biggest strengths lie in. We wanted to share that passion and provide a way to spread more unity between people. Art has a way of doing that."

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.
