According to researchers at Baylor College of Medicine, who are working in partnership with the Houston Health Department and Rice University, testing the city's wastewater for SARS-CoV2 can help predict where outbreaks are likely to happen.

In May, researchers analyzed wastewater samples that were collected every week from 39 sites in the city and found traces of the virus. The research project was directed by Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs.

"This is not Houston's first infectious disease crisis," Maresso says in a news release. "Wastewater sampling was pioneered by Joseph Melnick, the first chair of Baylor's Department of Molecular Virology and Microbiology, to get ahead of polio outbreaks in Houston in the 1960s. This work essentially ushered in the field of environmental virology, and it began here at Baylor. TAILOR Labs is just continuing that tradition by providing advanced science measures to support local public health intervention."

The researchers will continue into 2021 and are working with the city and local governments on their findings.

"It's a cost effective way to gauge Houston's total viral load. It tracks well ahead of positivity rate, 10 days in some cases," sways Dr. Austen Terwilliger, director of operations at TAILOR, in the release. "At the moment, we are at the lowest viral levels since we started sampling, which is excellent news."

University of Houston researchers looking into effect of pandemic on mental illness

While physical health and economic impacts of the coronavirus have been the focus of attention amid the pandemic, mental health effects are estimated to inflict more damage if not address, according to new research by Michael Zvolensky, University of Houston professor of psychology and director of the Anxiety and Health Research Laboratory/Substance Use Treatment Clinic.

Zvolensky has published two papers on his research discussing the psychological behavior issues related to the COVID-19 pandemic from a behavioral science perspective, according to a press release from UH.

"The impact of COVID-19 on psychological symptoms and disorders, addiction and health behavior is substantial and ongoing and will negatively impact people's mental health and put them at greater risk for chronic illness and drug addiction," reports Zvolensky in Behaviour Research and Therapy. "It will not equally impact all of society. Those at greater risk are those that have mental health vulnerabilities or disorders."

For those who 'catastrophize' the pandemic, Zvolensky explains in his paper, the impact from stress is increased — as is the possibility for substance abuse.

"That sets in motion a future wave of mental health, addiction and worsening health problems in our society. It's not going to go away, even with a vaccination, because the damage is already done. That's why we're going to see people with greater health problems struggling for generations," says Zvolensky in the release.

He evaluated a group of 160 participants on pandemic-related fear and worry and substance abuse as a coping method. The "results may provide critical clinical information for helping individuals cope with this pandemic," he says.

Can software help save lives in this pandemic? A Rice University computer scientist thinks it's worth a shot.

Bioinformatics researcher Todd Treangen is working with a molecular diagnostics company to optimize the design and computational evaluation of molecular detection assays for viral RNA of SARS-CoV-2, according to a press release from Rice. Great Basin Scientific and the Rice researchers hope their work will streamline the development and commercialization of COVID-19 testing.

"This exciting collaboration with Great Basin will allow for computational methods and software developed in my research group to directly contribute to fast, sensitive and affordable detection and monitoring of SARS-CoV-2 and emerging pathogens," Treangen said.

The company, which is based in Salt Lake City, will use Treangen lab's novel bioinformatics software called OliVar to work on the diagnostic test. Great Basin Scientific is expected to seek emergency use authorization for the test from the Food and Drug Administration later this year.

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.
