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.

University of Houston archaeologists make history with Mayan tomb discovery

History in the Making

Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

"Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

“The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.

Houston palliative care company integrates with Epic platforms

epic scale

Patients and medical teams using MyChart and other Epic Systems' software will now be able to access Houston-based Koda Health's AI-enhanced end-of-life planning platform.

The Houston-based palliative care company, which was born out of the TMC's Biodesign Fellowship, has integrated its advance care planning platform with Epic, one of the most widely used electronic health record (EHR) systems in the U.S., according to a news release.

Epic estimates that more than 325 million patients have a current electronic record in its systems.

“This is a significant milestone for our mission to make advance care planning scalable, meaningful, and seamless,” Tatiana Fofanova, CEO and co-founder of Koda Health, said in the release. “By integrating into systems already used by care teams, we help eliminate friction and ensure that care delivery honors what patients truly want—especially during serious illness and at the end of life.”

The partnership will streamline processes for both patients and clinicians. Users will be able to drop advance care plans directly into the Epic charts, which will be accessible through MyChart for patients and proxies and through Epic Hyperspace/Hyperdrive for care teams. Doctors can also initiate and manage advance care plans through a simple Epic order for patients.

According to Koda Health, its platform saves an average of $10,000 to $15,000 per patient. Roughly 85 percent of users complete advance care plan documents when using the platform, which is four times the national average.

“We developed Koda to give providers the time, training, and tools to guide these critical conversations," Dr. Desh Mohan, co-founder and chief medical officer at Koda Health, added in the statement. "Our integration now makes it possible to operationalize ACP at scale—aligned with value-based care goals and clinical reality.”

The company announced a partnership with Dallas-based Guidehealth, which integrates into primary care workflows and allows providers to identify high-risk patients, coordinate care and reduce administrative burden. Guidehealth works with more than 500,000 patients

Koda Health was founded in 2020 and closed an oversubscribed seed round for an undisclosed amount last year, with investments from AARP, Memorial Hermann Health System and the Texas Medical Center Venture Fund. The company also added Kidney Action Planning to its suite of services in 2024.
