In 2020, a group of researchers began testing Houston's wastewater to collect data to help identify trends at the community level. Now, the team's work has been rounded up to use as an online resource.

The Houston Health Department and Rice University launched the dashboard on September 22. The information comes from samples collected from the city's 39 wastewater treatment plants and many HISD schools.

"This new dashboard is another tool Houstonians can use to gauge the situation and make informed decisions to protect their families," says Dr. Loren Hopkins, chief environmental science officer for the health department and professor in the practice of statistics at Rice University, in a news release. "A high level of virus in your neighborhood's wastewater means virus is spreading locally and you should be even more stringent about masking up when visiting public places."

The health department, Houston Water, Rice University, and Baylor College of Medicine originally collaborated on the wastewater testing. Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs, led a part of the research.

"This is not Houston's first infectious disease crisis," Maresso says in an earlier 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."

It's an affordable way to track the virus, says experts. People with COVID-19 shed viral particles in their feces, according to the release, and by testing the wastewater, the health department can measure important infection rate changes.

The dashboard, which is accessible online now, is color-coded by the level of viral load in wastewater samples, as well as labeled with any recent trend changes. Houstonians can find the interactive COVID-19 wastewater monitoring dashboard, vaccination sites, testing sites, and more information at houstonemergency.org/covid19.

Here's when Houston can expect the Johnson & Johnson COVID-19 vaccine

coming soon

Texas can expect to receive the first 200,000 doses of the coveted Johnson & Johnson COVID-19 vaccine this week. The company announced that it has started the rollout process on March 1 — after the FDA approved its Emergency Use Authorization.

The Center for Disease Control gave the developer, Janssen Pharmaceutical, the final greenlight Sunday, February 28.

What does that mean for Houston? Mayor Sylvester Turner said the Houston Health Department is also anticipated to be on the list to receive Johnson & Johnson doses within the next seven days.

"That will be a game changer," Turner said at an event on February 28 afternoon. "There will be more vaccines available in a shorter period of time. We anticipate that we will probably get a shipment in sometime this week that will add to the Pfizer [doses] that we are using at NRG."

Turner said other clinics with the Houston Health Department have been administering the Moderna vaccine.

The Johnson & Johnson vaccine does have noticeable differences from the Pfizer and Moderna vaccines, experts said.

The MRNA vaccines each require two shots which are usually delivered weeks apart and stored in freezers. The Johnson & Johnson vaccine is a single shot that can be stored in a refrigerator for up to three months at 35 to 46 degrees.

However, Johnson & Johnson does not have as much of the COVID-19 vaccine produced as originally anticipated. ABC13 confirmed 3.9 million doses will be shipped out across the country this week. Johnson & Johnson announced roughly an additional 16 million doses by the end of the month.

"In the next few weeks, it won't have much of any impact because they only have at least three or four million doses available, and that's disappointing news," says Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine. "In the longer term, over the next few months, it's really important because we need a greater vaccine supply. We are not going to get there with the two MRNA vaccines. We need probably up to five different vaccines in order to vaccinate the American people."

Recently, there has been a decline in COVID-19 hospitalizations and COVID-19 cases reported statewide. As of Sunday, about 5,700 Texans are in the hospital due to COVID-19, which is half the number of hospitalization in the beginning of the month.

Infectious disease epidemiologist Dr. Catherine Troisi says it's important for people to not let their guard down and that people should get tested if they have been in a high-exposure situation, or if they have been in direct contact with someone who has tested positive.

"Get vaccinated, don't worry about what vaccine it is," Dr. Troisi notes. "It's true that unfortunately there are not as many doses right now of the Johnson & Johnson vaccine as we have hoped, but the company is saying that by the end of June, they will have a 100 million doses, and that's into 100 million people because you don't need two doses.

"So, we expect to have 600 million doses of the other two vaccines, that's 300 million people," she continues. "That should be enough for everyone who wants the vaccine to be able to get it. With one caveat and that is as of right now we do not have a vaccine for children under age 16. Those trials are going on, hopefully as we go throughout the year there will be a vaccine licensed to 12 year-olds and then maybe going down to 8 years or older."

City of Houston launches online registration for free COVID vaccinations

calling the shots

Since COVID-19 vaccinations arrived in Houston, locals have been clamoring for the inoculations. Now, the City of Houston has made it easier for those at highest risk to receive the injections.

The Houston Health Department launched online registration on January 4 for residents at highest risk of coronavirus disease to schedule appointments to receive free vaccinations. (A Spanish version is anticipated to launch as well, according to the city.)

Those in Phase 1B of the State of Texas' vaccine distribution are advised to use the new service. This includes those 65 and older or 18 and older with at least one chronic medical condition putting them at increased risk of severe illness or death.

Frontline healthcare workers — classified as Phase 1A in the distribution plan — who have yet to receive the vaccine also are eligible to sign up to get the shot through the health department, per a press release. The department currently offers the Moderna COVID-19 vaccine. More information can also be found here.

Meanwhile, appointments are also available through the health department's COVID-19 call center by calling 832-393-4220. The call center is open Monday through Saturday from 7:30 am to 4 pm and until 5 pm on Tuesdays and Thursdays.

Users will receive an appointment time and the location of the vaccination clinic site during the registration process. Staffers will screen visitors and direct them to a secure area to receive the vaccination and monitor them for any adverse reaction for 15 minutes, according to the city.

"The Houston Health Department is doing a phenomenal job getting the vaccine directly to people," said Mayor Sylvester Turner. "The new online registration, in addition to the call center, will make the process more efficient. While there is great public demand for the COVID-19 vaccine, there is also a lot of hesitancy. I understand the concerns, but I encourage all eligible Houstonians to get vaccinated to help stop the spread of the deadly virus."

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.
