Researchers across the world are coming up with innovative breakthroughs regarding the coronavirus, but Houston research institutions are also making health and wellness discoveries outside of COVID-19.

Here are three from Houston researchers from a muscular atrophy study from outer space to a research project that might allow blind patients to "see."

Houston Methodist researcher Alessandro Grattoni and his team published research on muscular atrophy in astronauts. The research was published in Advanced Therapeutics and focused on his 2017 RR-6 muscle atrophy study that was conducted on the International Space Station.

While the current standard practice for astronauts maintaining their muscles is working out over two hours a day, the research found that use of drugs could also help preserve muscles. On a SpaceX refuel mission, mice that were implanted with a "Nanofluidic Delivery System" were sent up to space and monitored, according to a report. The device gradually released small doses of formoterol, an FDA approved drug for use in bronchodilation that has also been shown to stimulate increased muscle mass.

University of Houston researchers are looking into the way the body responds to fear in order to enhance mental health treatment. Rose Faghih, assistant professor of electrical and computer engineering, and doctoral student Dilranjan Wickramasuriya in the Computational Medicine Lab (CML) are leading the project.

"We developed a mixed filter algorithm to continuously track a person's level of sympathetic nervous system activation using skin conductance and heart rate measurements," writes Faghih in the journal PLOS One. "This level of sympathetic activation is closely tied to what is known as emotional arousal or sympathetic arousal."

When this sympathetic nervous system is activated — sometimes known as the "fight or flight" response — the heart beats faster and more oxygen is delivered to the muscles, according to a press release. Then, the body begins to sweat in order to cool down.

"Using measurements of the variations in the conductivity of the skin and the rate at which the heart beats, and by developing mathematical models that govern these relationships, CML researchers have illustrated that the sympathetic nervous system's activation level can be tracked continuously," reports Faghih.

This algorithm could be used in a wearable electronic device that could be worn by a patient diagnosed with a fear or anxiety disorder.

When someone loses their vision, it's likely due to damage to the eyes or optic nerve. However, the brain that interprets what they eyes sees, works perfectly fine. But researchers from Baylor College of Medicine have worked on a thesis that a device with a camera could be designed and implemented to do the seeing for the blind patient.

"When we used electrical stimulation to dynamically trace letters directly on patients' brains, they were able to 'see' the intended letter shapes and could correctly identify different letters," says Dr. Daniel Yoshor, professor and chair of neurosurgery in a press release. "They described seeing glowing spots or lines forming the letters, like skywriting."

Through a study supported by the National Eye Institute with both sighted and blind people using implanted devices, the investigators determined that the process was promising. According to the release, the researchers identified several obstacles must be overcome before this technology could be implemented in clinical practice.

"The primary visual cortex, where the electrodes were implanted, contains half a billion neurons. In this study we stimulated only a small fraction of these neurons with a handful of electrodes," says said Dr. Michael Beauchamp, professor and in neurosurgery, in the release.

"An important next step will be to work with neuroengineers to develop electrode arrays with thousands of electrodes, allowing us to stimulate more precisely. Together with new hardware, improved stimulation algorithms will help realize the dream of delivering useful visual information to blind people."

Building Houston

Local workers who're especially dreading that commute or cracking open the laptop in the morning aren't alone. A new study reveals that nearly half of Houston laborers are more burned out on the job.

Some 49 percent of Bayou City residents report to be burned out at work, according to employment industry website Robert Half. That's significantly higher than last year, when only 37 percent reported burnout in a similar poll.

Meanwhile, more than one in four Houston workers (28 percent) say that they will not unplug from work when taking time off this summer.

Not surprisingly, American workers are ready for a vacation. Per a press release, the research also reveals:

  • One in four workers lost or gave up paid time off in 2020
  • One in three plans to take more than three weeks of vacation time this year

Elsewhere in Texas, the burnout is real. In Dallas, 50 percent of workers report serious burnout. More than a quarter — 26 percent — of Dallasites fear they won't disconnect from the office during summer vacation.

In fun-filled Austin, 45 percent of the workforce complain of burnout. Some 32 percent of Austinites feel they can unplug from work during the summer.

Fortunately for us, the most burned-out city in the U.S. isn't in the Lone Star State. That dubious title goes to the poor city of Charlotte, North Carolina, where 55 percent of laborers are truly worn out.
