Houston hospital system scores $4.8M gift, opens new Austin clinic, and more

news roundup

Texas Children’s Hospital has lots of exciting news this month. Chief among its big announcements is a $4.8 million gift that will help to fund the hospital’s new behavioral health Intensive Outpatient Program (IOP) in The Woodlands.

The donation comes from Ovintiv, a natural gas exploration and production company headquartered in Denver, Colorado.

The pledge makes Ovintiv the first company sponsor to join the Council of Hope, Texas Children’s new corporate giving society. The council’s fundraising priorities include supporting Texas Children’s behavioral health initiatives. Texas Children’s formed a Behavioral Health Task Force last year in order to expand and upgrade services for patients who need specialized help, hopefully preventing the necessity of in-patient care.

The IOP is expected to open early next year. It will treat patients for four or five hours a day, using individual, group and family therapy, art and music therapy programs, and yoga and recreational therapy to improve outcomes in behavioral health.

“This IOP is desperately needed in the Woodlands, and we are committed to creating it because we believe that the behavioral and developmental health of children, adolescents and teens is just as important as their physical well-being. Ovintiv’s transformational gift will make a life-changing difference for so many patients and their families,” says Dr. Kirti Saxena, chief of psychiatry at Texas Children’s Hospital and associate professor of psychiatry and behavioral sciences at Baylor College of Medicine, in a press release.

The Woodlands, however, isn’t the only city seeing the debut of a new facility from Texas Children’s. Last week, Texas Children’s Pavilion for Women announced the grand opening of its obstetrics and gynecology clinic in North Austin. The location welcomes women for fertility management, prenatal and preventative care, and a full spectrum of gynecological services.

That’s just the beginning for Texas Children’s and its reach in central Texas. In addition to the new OB/GYN clinic, Texas Children’s Hospital North Austin will open its doors in early February. It will provide care for women and children, especially in the areas of maternal-fetal medicine, and fetal intervention and neonatology.

Additionally, the Houston hospital has been named a Center of Excellence in antimicrobial stewardship (AMS) by bioMerieux, a world leader in in vitro diagnostics. Texas Children’s is one of three in the United States to net the honor, and the only one that specializes in pediatrics.

It’s no secret that antimicrobial resistance (AMR) is a bête noire of hospitals around the world. Common infectious diseases are becoming increasingly difficult to treat. By ensuring that patients get the right drug, at the right dose, at the right time, antimicrobial stewardship is extremely important to fighting resistance and to continuing antibiotic efficacy for future generations.

Texas Children’s and bioMérieux will collaborate to further activate antimicrobial resistance measures that will improve patient care. They’ll share expertise to develop and scale innovative best practices based on the application of diagnostic technology. And through all of its innovations, Texas Children’s will continue to be a global leader in pediatric care.

Houston hospitals soar on annual list ranking best in Texas

top health care

Houston Methodist Hospital now shares its status as the state’s best hospital with Dallas’ UT Southwestern Medical Center.

In U.S. News & World Report’s latest ranking of Texas hospitals, Houston Methodist and UT Southwestern share the No. 1 spot. Last year, Houston Methodist was the lone holder of first-place honors in Texas.

The Houston Methodist system comprises a primary care facility within the Texas Medical Center and six community hospitals across the region. In all, Houston Methodist operates more than 2,600 patient beds and employs more than 29,700 people.

Overall, Houston hospitals fared well in this year’s Texas rankings:

  • Houston Methodist, No. 1
  • Baylor St. Luke’s Medical Center, No. 3
  • Memorial Hermann Hospital-Texas Medical Center, No. 4
  • Memorial Hermann Greater Heights Hospital, No. 6
  • Houston Medical Sugar Land Hospital, No. 9
  • Memorial Hermann Memorial Medical Center, No. 10

Specialty institutions in Houston also garnered accolades.

For instance, the University of Texas MD Anderson Cancer Center ranked first in the country for cancer care. Since the inception of the U.S. News & World Report survey in 1990, MD Anderson has been among the country’s top two institutions for cancer care.

“At MD Anderson, we remain singularly focused on eliminating cancer,” Dr. Peter WT Pisters, president of MD Anderson, says in a news release. “We are pleased to see this commitment recognized, but there is work still to be done.”

For its part, Houston Methodist nabbed national rankings in 10 specialties, including No. 4 for diabetes and endocrinology and No. 5 for gastroenterology and GI surgery.

Elsewhere in the Houston area:

  • Texas Children’s Hospital nailed down the No. 1 ranking among children’s hospitals in the state.
  • TIRR Memorial Hermann was again ranked as the Best Rehabilitation Hospital in Texas.
  • The Texas Heart Institute at Baylor St. Luke’s Medical Center claimed the No. 2 ranking among cardiovascular, heart, and vascular surgery facilities in the state.
  • The Menninger Clinic again makes the top 10 psychiatric hospitals. It ranked No. 7 in that specialty.

“A recent survey of U.S. News users revealed more than four in five (84 percent) consider a hospital’s quality metrics to be important factors when deciding where to seek treatment for a serious medical issue,” Ben Harder, chief of health analysis and managing editor at U.S. News, says in a news release. “Consumers want useful resources to help them assess which hospital can best meet their specific care needs.”

Harder adds that his publication’s hospital rankings “offer patients and the physicians with whom they consult a data-driven source for comparing performance in outcomes, patient satisfaction, and other metrics that matter to them.”

Houston hospital opens next phase in $245M expansion

now open

Texas Children's Hospital has announced the opening of its newest medical tower in the Texas Medical Center.

Pavilion for Women Tower II is now open to patients, the Texas Children's Hospital revealed this week. It's the second phase of a $245 million expansion within the TMC. The new tower houses women’s services outpatient clinics and connects to the Pavilion for Women via a new sky bridge,

“I’ve always said that outgrowing a space is a good problem to have because it means that we’re doing something right and our patients and their families trust us to provide the safe and high-quality care they deserve,” says Mark A. Wallace, president and CEO of Texas Children’s, in a news release. “I am so proud of everything we’ve done together and I’m beyond grateful and excited for the continuous growth of Texas Children’s Pavilion for Women.”

The Pavilion for Women continues to grow its medical services, according to the release, including "pelvic medicine and reconstructive surgery, menopause treatment, maternal fetal medicine care, the Texas Children’s Fetal Center, reproductive psychiatry, reproductive endocrinology and infertility, and minimally invasive gynecology surgery."

“This latest milestone is one more indication of the dedication of Texas Children's Hospital to women's health,” Dr. Michael Belfort, OB/GYN-in-chief at Texas Children’s Pavilion for Women and professor and chair of the Department of Obstetrics and Gynecology at Baylor College of Medicine, says in the release. “That's very, very important to me. For the first time in this country, a children's hospital has embraced women throughout the spectrum of their health care from birth to menopause.”

The Baylor Obstetrics and Gynecology will relocate to the new tower by the end of the year. In 2024, TCH will add more adult inpatient and neonatal intensive care beds.

“This investment in our Pavilion for Women will allow us to increase delivery volumes significantly, but additionally the added space will also allow us to continue to grow those specialized clinics that cater to women at every stage of their life,” says Michele Birsinger, assistant vice president of Women's Services at Texas Children’s Pavilion for Women.

The Texas Medical Center is also undergoing a major renovation to create Helix Park, a complex with a few new multidisciplinary buildings for research, innovation, and health care. The first of the buildings, the TMC3 Collaborative Building, is expected to deliver this year.

As director of social innovation at Teach For America Houston, it's Sarah Essama's job to come up with new ways for the organization to support both students and teachers. But, as she explains on the Houston Innovators Podcast this week, Essama realized a huge lesson modern students needed was to learn this innovation process themselves.

This line of thinking turned into Essama founding The Dream Lab, powered by Teach for America Houston.

"The Dream Lab is a set of immersive design spaces where young people leverage their imagination and creativity to innovate and solve problems within their community," she explains.

Last month, the new concept rolled out to high school students in partnership with DivInc Houston, a nonprofit focused on social and economic equity in entrepreneurship, and 21 ninth graders spent the day at the Ion for a mini-innovation accelerator and design showcase. Click here to read more.

A Houston-based virtual reality training provider has closed its first round of funding. HTX Labs announced last month that it has received a $3.2 million investment from Cypress Growth Capital.

“We have been looking to secure outside capital to accelerate the growth of our EMPACT platform and customer base but we hadn’t found the right partner who provided an investment vehicle that matched our needs,“ says HTX Labs CEO Scott Schneider in the release. “We found everything we were looking for in Cypress Growth Capital. They have a non-dilutive funding model that aligns with our capital expectations and have the level of experience that really makes this smart money.

The fresh funding will go toward growing and scaling the company's operations — both within the current Department of Defense and expansion opportunities into key commercial markets, like heavy industry, manufacturing, and higher education. Additionally, the funding will support increased customer adoption. Click here to read more.

Houston team’s discovery brings solid-state batteries closer to EV use

A Better Battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.
