Houston — home to one of the largest medical centers in the world — isn't a stranger when it comes to medical innovations and breakthrough research discoveries.

In the latest roundup of research innovations, four Houston institutions are working on innovative and — in some cases — life-saving research projects.

Houston Methodist study observes that strep throat germ is becoming resistant to antibiotics

Researchers at Houston Methodist have discovered some troubling information about the strains of group A streptococcus that cause strep throat and a flesh-eating disease are becoming more resistant to beta-lactams antibiotics like penicillin.

James M. Musser is the lead author of the study and chair of Methodist's Department of Pathology and Genomic Medicine. The study — which received funding from grants from the Fondren Foundation, Houston Methodist Hospital and Houston Methodist Research Institute, and the National Institutes of Health — appeared in the Jan. 29 issue of the Journal of Clinical Microbiology, according to a news release.

"If this germ becomes truly resistant to these antibiotics, it would have a very serious impact on millions of children around the world," Musser says in the release. "That is a very concerning but plausible notion based on our findings. Development of resistance to beta-lactam antibiotics would have a major public health impact globally."

Musser and his team found 7,025 group A streptococcus strains that have been recorded around the world over the past several decades. Of those strains, 2 percent had gene mutations that raised the alarm for the researchers and, upon investigation, Musser's team came to the conclusion that antibiotic treatments can eventually be less effective — or even completely ineffective. This, Musser says, calls for an urgent need to develop a vaccine.

"We could be looking at a worldwide public health infectious disease problem," says Musser in the release. "When strep throat doesn't respond to frontline antibiotics such as penicillin, physicians must start prescribing second-line therapies, which may not be as effective against this organism."

Mehmet Orman, assistant professor of chemical and biomolecular engineering at the University of Houston, is looking into a specific type of persister cells that have been found to be stubborn and drug-resistant.

The research, which is backed by a $1.9 million grant from the National Institute of Allergy and Infectious Diseases, could answer questions about chronic health issues like airway infections in cystic fibrosis patients, urinary tract infections, and tuberculosis, according to a news release.

"If we know how persister cells are formed, we can target their formation mechanisms to eliminate these dangerous cell types," says Orman in a news release.

Orman is looking into cells' self-digestion, or autophagy, process that is found to stimulate persister formation. Per the release, cells can survive periods of starvation by eating their own elements. Specifically, Orman will analyze self-digestion in E. coli.

"By integrating our expertise in bacterial cell biology with advanced current technologies, we aim to decipher the key components of this pathway to provide a clear and much-needed picture of bacterial self-digestion mechanisms," says Orman in the release.

Baylor College of Medicine is working to understand and prevent post-op kidney failure

Scientists at Baylor College of Medicine are looking into the lead cause of kidney failure in patients who undergo surgery. Individuals who have heightened levels of suPAR protein — soluble urokinase-type plasminogen activator receptor — have a greater risk of this post-op complication, according to a news release.

"suPAR is a circulating protein that is released by inflammatory cells in the bone marrow and produced by a number of cell/organs in the body," says Dr. David Sheikh-Hamad, professor of medicine – nephrology at Baylor College of Medicine and collaborating author of the study, in the release.

The study, which was published in The New England Journal of Medicine, conducted research on mice that were engineered to hive high suPAR levels in their blood. Compared to the control mice, the suPAR mice had more risk of kidney industry. These mice were given suPAR-blocking antibodies, which then helped reduce kidney injury.

"This protective strategy may be used in humans expressing high suPAR levels prior to contrast exposure, or surgery to decrease the likelihood of developing kidney failure," Sheikh-Hamad says in the release.

Rice University research finds expressing emotions during mourning is healthier

A new study done by researchers at Rice University finds that spouses that lose their husband or wife and try to suppress their grief are not doing themselves any favors. The study monitored 99 people who had recently lost a spouse, according to a news release.

"There has been work focused on the link between emotion regulation and health after romantic breakups, which shows that distracting oneself from thoughts of the loss may be helpful," says Christopher Fagundes, an associate professor of psychology and the principal investigator, in a news release. "However, the death of a spouse is a very different experience because neither person initiated the separation or can attempt to repair the relationship."

The study included asking participants to respond to how they felt about certain coping strategies, as well as blood tests to measure cytokines levels‚ an inflammatory marker.

"Bodily inflammation is linked to a host of negative health conditions, including serious cardiovascular issues like stroke and heart attack," Fagundes says in the release.

The research, which was funded by a grant from the National Heart, Lung, and Blood Institute, found that the participants who avoided their emotions suffered more of this bodily inflammation.

"The research also suggests that not all coping strategies are created equal, and that some strategies can backfire and have harmful effects, especially in populations experiencing particularly intense emotions in the face of significant life stressors, such as losing a loved one," adss Richard Lopez, an assistant professor of psychology at Bard College and lead author of the study, in the release.

Building Houston

With a new CEO and chief operating officer aboard, Houston-based DataJoint is thinking small in order to go big.

Looking ahead to 2022, DataJoint aims to enable hundreds of smaller projects rather than a handful of mega-projects, CEO Dimitri Yatsenko says. DataJoint develops data management software that empowers collaboration in the neuroscience and artificial intelligence sectors.

"Our strategy is to take the lessons that we have learned over the past four years working with major projects with multi-institutional consortia," Yatsenko says, "and translate them into a platform that thousands of labs can use efficiently to accelerate their research and make it more open and rigorous."

Ahead of that shift, the startup has undergone some significant changes, including two moves in the C-suite.

Yatsenko became CEO in February after stints as vice president of R&D and as president. He co-founded the company as Vathes LLC in 2016. Yatsenko succeeded co-founder Edgar Walker, who had been CEO since May 2020 and was vice president of engineering before that.

In tandem with Yatsenko's ascent to CEO, the company brought aboard Jason Kirkpatrick as COO. Kirkpatrick previously was chief financial officer of Houston-based Darcy Partners, an energy industry advisory firm; chief operating officer and chief financial officer of Houston-based Solid Systems CAD Services (SSCS), an IT services company; and senior vice president of finance and general manager of operations at Houston-based SmartVault Corp., a cloud-based document management company.

"Most of our team are scientists and engineers. Recruiting an experienced business leader was a timely step for us, and Jason's vast leadership experience in the software industry and recurring revenue models added a new dimension to our team," Yatsenko says.

Other recent changes include:

  • Converting from an LLC structure to a C corporation structure to enable founders, employees, and future investors to be granted shares of the company's stock.
  • Shortening the business' name to DataJoint from DataJoint Neuro and recently launching its rebranded website.
  • Moving the company's office from the Texas Medical Center Innovation Institute (TMCx) to the Galleria area. The new space will make room for more employees. Yatsenko says the 12-employee startup plans to increase its headcount to 15 to 20 by the end of this year.

Over the past five years, the company's customer base has expanded to include neuroscience institutions such as Princeton University's Princeton Neuroscience Institute and Columbia University's Zuckerman Institute for Brain Science, as well as University College London and the Norwegian University of Science and Technology. DataJoint's growth has been fueled in large part by grants from the U.S. Defense Advanced Research Projects Agency (DARPA) and the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative at the National Institutes of Health (NIH).

"The work we are tackling has our team truly excited about the future, particularly the capabilities being offered to the neuroscience community to understand how the brain forms perceptions and generates behavior," Yatsenko says.
