Virtual reality goes far beyond playing games with titles like Arizona Sunshine, Moss, Robo Recall, and Tetris Effect. VR also is playing an ever-growing role in health care settings. The global market for VR in health care could reach $3.8 billion in 2020, according to one estimate.

VR is touching all corners of heath, including robotic surgeries, training, pain management, and behavior modification, according to InterbrandHealth, a health care branding agency. And these technologies are happening right here in Houston.

Researchers at Houston Methodist Cancer Center are exploring whether exposure to nature, through either a real garden or VR, can ease pain and distress in cancer patients who are undergoing chemotherapy. This approach might decrease the need for prescription painkillers.

Houston Methodist and Texas A&M University are leading this test. Renee Stubbins, a clinical dietitian at Houston Methodist Cancer Center, and Ashley Verzwyvelt, an infusion oncology nurse at the cancer center, proposed the research after several years of studying ways that nature can boost the healing process.

"Anything that affects our patients' comfort — including easing pain and anxiety, and possibly reducing the need for pain medications — is important to their recovery," Stubbins says in a release. "People have an innate connection to nature, and we hope the patients will respond positively."

Three dozen cancer patients receiving chemotherapy infusions every two weeks during at least six cycles will be randomly assigned to one of three rooms: a live-garden-view room; a window-less room, and a room where nature can be experienced through a VR headset.

Teaming up with Houston-based Skyline Art Services, local artist Gonzo247 produced a nature-inspired mural on a wall behind the live garden to create an immersive environment. The mural depicts a flowering garden, blue sky and sunset that enhance the live garden of Texas wildflowers in the foreground.

Researchers will measure pain, distress, blood pressure, heart rate, and saliva cortisol at the beginning and end of each infusion visit. Saliva cortisol, a hormone produced when the body is stressed, helps gauge a patient's condition.

"If this study proves that real or virtual elements of nature help the healing process, then it has potential to positively impact our patients," Verzwyvelt says. "Some of them are hesitant to take pain medication due to concerns of addiction and adverse side effects, so I'm excited to see the possibilities this kind of research could bring."

Houston Methodist Cancer Center says the VR experiment could have implications for treatment of an array of patients who are immobile or whose immune systems are compromised.

"We looked at multiple studies that showed exposure to nature can reduce stress levels and actually increase productivity and creativity," says Ann McNamara, associate professor in the Department of Visualization at Texas A&M. "We want to see if we can reproduce those effects in a natural environment in virtual reality."

The study is being financed by the Center for Health & Nature, a joint initiative of Houston Methodist, Texas A&M and Texan by Nature, a nonprofit conservation group founded by former first lady Laura Bush. The Center for Health & Nature, housed at Houston Methodist Hospital, debuted in 2018.

"There's a gap in research regarding what nature factors lead to increased health, what exposure to nature means, and how much exposure is needed," Bush said when the center was announced.

Houston team develops low-cost device to treat infants with life-threatening birth defect

infant innovation

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Generally, a single-use bag can cost between $200 and $300. The alternatives that exist lack structure and require surgical sewing. This is where the SimpleSilo comes in.

“We focused on keeping the design as simple and functional as possible, while still being affordable,” Vanshika Jhonsa said in a news release. “Our hope is that health care providers around the world can adapt the SimpleSilo to their local supplies and specific needs.”

The study was published in the Journal of Pediatric Surgery, and Jhonsa, its first author, also won the 2023 American Pediatric Surgical Association Innovation Award for the project. She is a recent Rice alumna and is currently a medical student at UTHealth Houston.

Bindi Naik-Mathuria, a pediatric surgeon at UTMB Health, served as the corresponding author of the study. Rice undergraduates Shreya Jindal and Shriya Shah, along with Mary Seifu Tirfie, a current Rice360 Global Health Fellow, also worked on the project.

In laboratory tests, the device demonstrated a fluid leakage rate of just 0.02 milliliters per hour, which is comparable to commercial silo bags, and it withstood repeated disinfection while maintaining its structure. In a simulated in vitro test using cow intestines and a mock abdominal wall, SimpleSilo achieved a 50 percent reduction of the intestines into the simulated cavity over three days, also matching the performance of commercial silo bags. The team plans to conduct a formal clinical trial in East Africa.

“Gastroschisis has one of the biggest survival gaps from high-resource settings to low-resource settings, but it doesn’t have to be this way,” Meaghan Bond, lecturer and senior design engineer at Rice360, added in the news release. “We believe the SimpleSilo can help close the survival gap by making treatment accessible and affordable, even in resource-limited settings.”

Oxy's $1.3B Texas carbon capture facility on track to​ launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
