5 Questions With Dr. Jessica Gill

Each year, millions of Americans suffer sports-related concussions, and the number of youth suffering from these traumatic brain injuries has been rising. Blows to the head are common in sports such as football and hockey, and when these forces are strong enough to cause a concussion, they can harm the brain and impair cognitive functioning. Although concussions occur in staggering numbers, scientists do not fully understand what happens to the brain at the time of concussion or during the recovery period. However, that doesn’t mean they’re not trying.
Potential biomarker may contribute to personalized treatments

Until recently, medical treatment has largely been one-size-fits-all, with doctors unable to separate patients into distinct groups that might benefit more or less from a particular approach. However, researchers are increasingly finding that individuals with the same disease can differ markedly in ways that might one day influence their care. A recent IRP study has identified a particular molecule that may have just such an impact for patients with damaged lungs.

In 2016, more than one in twenty American adults and one in ten adolescents experienced at least one major depressive episode. For nearly 45,000 of these individuals, their condition was severe enough that it led them to take their own lives. Unfortunately, the medications currently available to treat depression are not always effective and can take up to six weeks to substantially reduce symptoms.
To improve treatment and accelerate symptom relief, IRP senior investigator Carlos Zarate Jr., M.D., is working towards the development of new medications for depression, along with the identification of new drug targets and objective measures called biomarkers that yield information about how a patient is responding to treatment. In recent years, his lab has extensively investigated and assessed the effects of the anesthetic drug ketamine on depression and suicidal thoughts. Many of the patients in his trials have had marked and rapid responses to ketamine, sometimes within a single day or just a couple of hours.
On Tuesday, November 13, Dr. Zarate participated in a Reddit “Ask Me Anything” (AMA) to answer questions from the public about the way depression is currently treated and the latest efforts to develop cutting-edge therapies for the condition. Read on for some of the most interesting exchanges that took place or check out the full AMA on Reddit.

Like a bear leaves its ominous footprints in the snow, diseases and other biological processes often leave traces throughout our bodies. Recent technological and scientific advances have enabled clinicians to use measurements of these ‘biomarkers’ in their attempts to improve our health. A new study by IRP researchers revealed that patients with a sleep disorder called obstructive sleep apnea (OSA) have higher blood concentrations of certain biomarkers that may foreshadow poor brain health later in life.1
When people with OSA sleep, their throat muscles relax and block their windpipes, preventing proper breathing and often waking them up. As a result, these individuals get lower-quality sleep and their brains receive less oxygen at night.
“The overall idea is that those two conditions are not good for brain health, but nobody had really looked to see if some of the biomarkers we see in brain injury are also common in younger individuals with this type of disordered breathing,” says IRP Lasker Clinical Research Scholar Jessica Gill, Ph.D., R.N., the study’s senior author.
