A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, an associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration, according to a news release from UH.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient. The results of their study, led by Mubasher Iqbal, a Ph.D. candidate in biomedical engineering at UH, were published recently in the journal Nature Communications.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said in a news release. “Our study is the first to solve this problem.”

Hyperleukocytosis is a condition that develops when the body has an extremely high number of white blood cells, which in many cases is due to leukemia. According to the release, up to 20 percent to 30 percent of patients with acute leukemia develop hyperleukocytosis, and this places them at risk for potentially fatal complications.

The new device utilizes tiny channels—each about the width of a human hair—to efficiently separate blood cells through controlled incremental filtration. According to Lam, the team was excited that the new device could operate at clinically relevant flow rates.

The device successfully removed approximately 85 percent of large leukocytes and 90 percent of leukemic blasts from undiluted human whole blood without causing platelet loss or other adverse effects. It also operates with an ECV that’s about 1/70th of conventional leukapheresis machines, which makes it particularly suitable for infants and small children.

“Overall, our study suggests that microfluidics leukapheresis is safe and effective at selectively removing leukocytes from circulation, with separation performance sufficiently high to ultimately enable safe leukapheresis in children,” Shevkoplyas said in the release.

Houston health tech company tapped for prestigious pediatric medical device competition

ready to pitch

Houston-based medtech company CorInnova is gearing up for what could be a big payday.

CorInnova is among five medtech companies that have been invited to present pitches in October for the National Capital Consortium for Pediatric Device Innovation’s “Make Your Medical Device Pitch for Kids!” competition.

CorInnova and the four other finalists now have access to a four-month pediatric accelerator program led by MedTech Innovator and will vie for a share of $150,000 in grant funding from the U.S. Food and Drug Administration (FDA). The pitch event is part of the 10th annual Symposium on Pediatric Device Innovation.

“Addressing unmet needs across pediatric populations is critical to advancing children’s health, and we are delighted to once again work with pioneering companies that seek to bridge this care gap,” says Kolaeh Eskandanian, president and chief innovation officer at Children’s National Hospital and principal investigator for the pediatric device consortium.

CorInnova has developed a minimally invasive device for the treatment of congestive heart failure. Specifically, CorInnova’s soft, flexible device can be inserted through a 1-inch incision to increase the amount of blood pumping in the heart by 50 percent.

The device’s primary benefit is that there’s no contact with blood, thus minimizing complications when the device is being used. Blood contact during a heart procedure can increase the risk of health problems such as stroke and kidney disfunction.

“The device is collapsible, allowing it to be delivered and secured to the heart in a minimally invasive manner. The device conforms to the heart’s surface, and gently compresses the heart to increase cardiac output using an external pneumatic driver that operates in synchrony with the heartbeat,” CorInnova explains on its website.

In the U.S., around 40,000 babies are born each year with congenital heart defects. About one-fourth of these newborns have critical defects, often prompting the need for surgery or other procedures.

Since being founded in 2004, CorInnova has raised at least $6.3 million, according to Crunchbase. This includes a $6.1 million investment from Wellcome Trust, a London-based charitable foundation that focuses on biomedical research.

Aside from the MedTech Innovator accelerator, CorInnova has participated in the TMC Accelerator’s fall 2019 accelerator program for medical device makers and the fall 2018 gBETA Medtech accelerator program.

The four other finalists in the medtech pitch competition are:

  • La Palma, California-based Innovation Lab, whose mechanical elbow brace stabilizes tremors in some pediatric patients with cerebral palsy.
  • Biddeford, Maine-based Prapela, whose vibrating pad helps treat apnea in newborns.
  • Richmond, Virginia-based Tympanogen, whose nonsurgical procedure takes the place of surgery for eardrum repair.
  • Xpan of Concord, Ontario, Canada, whose universal trocar (a surgical instrument) improves safety, access, and flexibility during various procedures.

Houston company awarded $2.5B NASA contract to support astronaut health and space missions

space health

Houston-based technology and energy solution company KBR has been awarded a $2.5 billion NASA contract to support astronaut health and reduce risks during spaceflight missions.

Under the terms of the Human Health and Performance Contract 2, KBR will provide support services for several programs, including the Human Research Program, International Space Station Program, Commercial Crew Program, Artemis campaign and others. This will include ensuring crew health, safety, and performance; occupational health services and risk mitigation research for future flights.

“This contract reinforces KBR’s leadership in human spaceflight operations and highlights our expertise in supporting NASA’s vision for space exploration,” Mark Kavanaugh, KBR president of defense, intel and space, said in a news release.

The five-year contract will begin Nov. 1 with possible extension option periods that could last through 2035. The total estimated value of the base period plus the optional periods is $3.6 billion, and the majority of the work will be done at NASA’s Johnson Space Center.

“We’re proud to support NASA’s critical work on long-duration space travel, including the Artemis missions, while contributing to solutions that will help humans live and thrive beyond Earth,” Kavanaugh adde in the news release.

Recently, KBR and Axiom Space completed three successful crewed underwater tests of the Axiom Extravehicular Mobility Unit (AxEMU) at NASA's Neutral Buoyancy Laboratory (NBL) at Johnson Space Center. The tests were part of an effort to help both companies work to support NASA's return to the Moon, according to a release.

KBR also landed at No. 3 in a list of Texas businesses on Time and Statista’s new ranking of the country’s best midsize companies.

UH receives $1M grant to advance research on rare pediatric disorder

peds research

The University of Houston has received a two-year, $1.1 million gift from the Cynthia and George Mitchell Foundation to advance research on a rare genetic disorder that can lead to both deafness and blindness in children, known as Usher Syndrome.

The current grant will support the research of UH biomedical engineering professors Muna Naash and Muayyad Al-Ubaidi, who work in the Laboratory for Retinal Molecular and Cellular Biology and Gene Therapy in the Cullen College of Engineering. The professors have published their findings in the journal Nature Communications.

Naash and Al-Ubaidi’s research focuses on mutations in the USH2A gene, which is crucial to the development and maintenance of the inner ear and retina. The work was inspired by a chance meeting that changed Naash’s life.

“Our work began more than two decades ago when I met a young boy who had lost his both his vision and hearing, and it made me realize just how precious those two senses are, and it truly touched my heart,” Naash said in a news release from UH. “Thanks to the generosity of the Cynthia and George Mitchell Foundation, we can now take the next critical steps in our research and bring hope to families affected by this challenging condition.”

The grant from the foundation comes in addition to a previous $1.6 million award from the National Eye Institute in 2023, which helped create a research platform for innovative gene therapy approaches for the condition.

Usher Syndrome affects 25,000 people in the U.S. and is the most common genetic condition worldwide that impacts both hearing and vision in children. Currently, there is no cure for any of the main three types of the condition. UH believes support from the Cynthia and George Mitchell Foundation will help elevate research, advance real-world solutions in health and improve lives.

“What makes UH such a powerful hub for research is not just its own resources, but also its location and strategic partnerships, including those with the Texas Medical Center,” Al-Ubaidi said in a news release. “We have access to an extraordinary network, and that kind of collaborative environment is essential when tackling complex diseases like Usher syndrome, where no single lab can do it alone.”

Members-only coworking club Switchyards to open first Houston location

Where to Work

An innovative take on the coworking space is coming to Houston. Switchyards will open its first location in the Bayou City on Monday, September 29.

Located in the former Buffalo Exchange at 2901 S Shepherd Drive, Switchyards is well located on the border of Montrose, River Oaks, and Upper Kirby. Founded in Atlanta, the Houston location will join 30 outposts in cities such as Austin, Dallas, Denver, Kansas City, and Nashville.

Unlike WeWork, which caters to companies looking for office space for groups of employees, Switchyards pitches itself as a club for individuals who want to get a little work done away from their home offices.

“Working from home all the time is pretty lonesome,” Switchyards creative director Brandon Hinman says. “It feels good to have places to get out and mix it up. To change paces and change scenery.”

Switchyards facilitates that change of scenery with an environment that blends touches of hotel lobbies, college libraries, and coffee shops. As seen in the photos of the company’s other location, the furniture is a mix of desks, comfy chairs, and couches for individuals or small groups. It’s a far cry from the cube farms of the Office Space era.

“They tend to be historic, textured, layered,” Hinman says about the company’s locations. “A lot of really good furniture. Really thoughtful for getting a couple hours of work done.”

Each location features fast wi-fi, plenty of electrical outlets, and good quality coffee and tea. All 250 members have 24/7 access to the space. And by choosing the real estate they lease carefully, Switchyards keeps its membership price to $100 per month.

“Packaging it together like that and opening in these neighborhoods where people actually live has been pretty magical,” Hinman says. "The big opportunity, I think, is that 90 percent of our members have never had a shared space before. It is unlocking a new thing for people.”

Those who are interested in learning more can sign up at switchyards.com/houston-tx to get early access to memberships and an invite to a sneak peek party.

Memberships go on sale Thursday, September 25 at 10 am. Switchyards notes that the last 14 clubs have sold out on day one.
