While so many of Houston's venture capital groups and entrepreneurs have been figuring out the best ways to navigate fundraising amid a pandemic, Diane Yoo managed to close an oversubscribed initial fund and deployed investments into health tech startups during COVID-19 — while also recovering from the disease itself.

Entrepreneur turned investor Diane Yoo launched her health tech-focused venture capital fund, Medingenii Capital, last year, but didn't start fundraising for its initial fund until this year.

Yoo says she and her partners, entrepreneur and investor Greg Campbell, neurologist Dr. Eddie Patton, Dr. Sreedhar Mandayam, and investor Gen Fukunaga, were virtually meeting with over a dozen potential investors weekly and closed the round in under two months.

It was right around closing when Yoo says she caught COVID-19.

"It ravaged every part of my body, and I ended up having to be hospitalized because I couldn't breathe," she says.

Yoo recovered after a month and a half of enduring the disease, only to come out of that experience to fund innovative Houston companies working on COVID-19 solutions. Medingenii focuses on early stage health tech, including genomics, health IT, medical devices, and patient engagement.

"The pandemic has really validated some of the business models we're invested in," she tells InnovationMap.

One example from Medingenii's portfolio is Houston-based medical device company, Vitls. The company's technology includes a wearable device that can monitor vital signs and sync with a smartphone app and sends key information to doctors remotely.

As Yoo thinks back to her COVID-19 treatment, Vitls could have helped her and her fellow patients get out of the crowded hospital wing and home to recover sooner — with the peace of mind of remote care thanks to the device.

"When I was in the ER room, it was overcrowded," Yoo says. "If you were not seriously ill, they would dismiss you because there was just no room. But if you went home with Vitls, you could have sent all your vitals to your doctor from home."

Fueled by a mission to find more health tech solutions like Vitls and with the quick pace of her first fund — Yoo says she's already deployed the capital into Houston-based startups and is looking toward the second fund, which will again focus on Houston startups.

"We really love Houston," Yoo says. "We want to invest a lot of our fund here, and we continue to do that and plan to do that. We see a lot of opportunity in Houston and look forward to working with the innovation ecosystem here."

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.
