ITM-UChicago researcher Dimitra Skondra, MD, PhD, Professor of Ophthalmology and Visual Science, kicked things off with a talk on battling blindness with a diabetes pill.
“Vision is something we take for granted, all of us,” said Skondra, who is exploring a potential way to help people avoid blindness.
Age-related macular degeneration (AMD) is the leading cause of blindness in anyone over the age of 50 in the United States. There is no prevention and no treatment for 90% of patients, Skondra said, except for a monthly shot directly into the eye. This cringey option costs the U.S. economy billions of dollars.
Age-related macular degeneration (AMD) is the leading cause of blindness in anyone over the age of 50 in the United States.

But a different option may be just a clinical trial away.
While treating patients in clinic, Skondra noticed a trend with elderly patients who happen to have diabetes and take a diabetes medication called metformin. These 90-year-olds “have retinas of 20-year-olds,” Skondra said.
She received pilot funding to learn more about the relationship and her findings support her idea that the medication can help. Metformin promoted healthy aging through a healthy and happy microbiome, or the collection of bacteria and microorganisms inside us. Her study in mice found that just two weeks of metformin stopped AMD. The next step is a clinical trial in humans.
“What if I told you that there are simple things that we can do in our everyday life to hopefully prevent the onset of or delay the onset of brain changes and dementia and Alzheimer’s disease as we age,” Halloway asked the audience.
Halloway’s research found that just 30 minutes of daily activity that gets the heart rate up is enough to improve blood flow to the brain and help form that protective bubble that helps preserve memory and thinking – and hopefully prevent or delay the onset of dementia. However, she warned that too much sitting can offset the positive health benefits we get from exercise.
Next steps for Halloway include a nation-wide project that studies the extent to which small changes in behavior can improve brain health.
ITM-UChicago researcher Mohan S. Gundeti, MD, Professor of Surgery, Pediatrics, and Obstetrics and Gynecology, followed by presenting his work on using artificial intelligence to help diagnose a kidney condition called hydronephrosis that affects about 1 in 100 newborns.
“Children are the future, and I spend all (my) life taking care of children,” Gundeti said. “That’s my life’s purpose.”
There are different grades, or stages, of hydronephrosis – the mildest will resolve on its own and the most severe will require the infant to have surgery. The problem lies with human differences when diagnosing the stage of the condition. One ultrasound is commonly given two separate grades by two different specialists, leaving parents with tremendous uncertainty. But AI might be able to help.
Last to present was ITM-UChicago researcher Jessica Ridgway, MD, Associate Professor of Medicine, on her work in preventing HIV in women of color with the medication PrEP. Ridgway shared the story of a pregnant patient who was newly diagnosed with HIV. The patient didn’t even know there was a medication she could take to prevent HIV.
“She had no symptoms of HIV,” Ridgway said. “She’d been tested for HIV before and it had been negative. She’d been to see doctors no one had ever before told her that there was something she could do, or a medication she could take to prevent HIV. She was upset and angry and worried. That really stuck with me.”
While there is no cure for HIV, PrEP is a medication that people can take to prevent it. There are a lot of people who could benefit from using it, she said, but mostly men get offered the medication. Ridgway said that women account for 19% of new HIV cases, but they only make up 8% of PrEP users.
In her ITM-funded pilot project, Ridgway’s goal was to create an AI algorithm to identify women who would benefit from PrEP and to understand women’s perspectives about this process. The overall opinions of the over 100 women her team spoke with were positive, though some had reservations around privacy and potential discrimination. Ridgway is now doing ongoing work to make the algorithm better.
