Five Questions with Dr. Nehal Mehta
Thursday, August 29, 2019
Most Americans know someone who has been affected by heart disease. Despite its status as the leading cause of death in the U.S. today, rates of heart disease have actually been steadily falling since they hit their peak in 1968. In fact, between 1970 and 2005, the life expectancy of the average American increased over 70 percent due in part to reductions in heart disease-related deaths.
Research conducted by IRP scientists has played a key role in curbing the heart disease epidemic by helping identify now well-known risk factors for heart disease, such as high blood pressure, obesity, and physical inactivity. However, not all risk factors are so commonly known. A 2017 study by IRP Lasker Clinical Research Scholar Nehal Mehta, M.D., M.S.C.E., revealed that untreated psoriasis — a chronic, relapsing, inflammatory skin disease — is linked to an elevated risk for premature coronary artery disease. Dr. Mehta’s research demonstrated a strong link between psoriasis-induced skin inflammation and and inflammation of the blood vessels, a precursor to heart disease. Through this study, the largest ongoing study of individuals with psoriasis to-date, Dr. Mehta’s team has concluded that controlling psoriasis-associated skin disease could be an important means of reducing cardiac risk in this population.

Expert estimates suggest that more than 5.5 million Americans may have dementia caused by Alzheimer’s, a disease currently ranked as the sixth-leading cause of death in the United States. Because of the condition’s growing prevalence and profound consequences for patients, understanding Alzheimer’s disease and other forms of cognitive decline is an important goal within the Intramural Research Program.
One example of the IRP’s many contributions to the field of Alzheimer’s research is a 2013 study that detected brain changes in older adults who would go on to develop cognitive impairment years before their memory began to fail. This research, led by IRP staff scientist Lori Beason-Held, Ph.D., aimed to understand who might be susceptible to developing Alzheimer’s disease and what factors contribute to the development of the disease before symptoms appear.

For Americans and others living outside the tropics, a mosquito bite is nothing more than an itchy inconvenience, but for billions of others, it can lead to a life-or-death battle with malaria. In some cases, the illness can wreak havoc on the brain. A new IRP study has used magnetic resonance imaging (MRI) technology to demonstrate that an investigational therapy can reverse that damage in mice.

With summer winding down, it's about time we took another dive into some NIH history! These new additions to the NIH Stetten Museum collection feature some of the most prominent investigators ever to walk the NIH campus, including a Nobel prize winner and a scientist who made important discoveries about how electricity travels between neurons.

To paraphrase President Obama from his guest editorial in the November issue of Wired magazine, there’s never been a better time to be alive. One NIH institute leading us into the future is the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which supports avant-garde investigators at the nexus of engineering and the physical and life sciences with innovations that improve global health.

If you were going to train an artificial intelligence (AI) system to understand and accurately diagnose medical images, what kind of information do you think would be most effective: lots of general image data, or small amounts of specific data?

Scientists in the NIH Intramural Research Program (IRP) go to work each day in the biomedical equivalent of a candy store. The advanced equipment and shared tools readily available to researchers doing basic, translational, and clinical science in the IRP are unmatched anywhere else, which enables high efficiency and productivity within the IRP’s unique discovery model.

Until recently, visualizing many of the processes underlying human diseases had been almost impossible. The NIH IRP’s role in developing technologies that can peer into human organs and cells is a key component of the Long-Term Intramural Research Program Planning Report and basis of sessions during this year’s #ResearchFest.

As a child I liked robots. Growing up in Korea, I liked cartoons and movies where people were on a mission to save the world with the robots they invented, and I wanted to develop a superhero robot someday, too. While my robot isn’t yet complete, the path I followed in pursuit of my goals eventually led me to explore data analysis.
And here I am, a postdoc at the NIH—probably the largest healthcare research institution in the world—in the Imaging Biomarkers and Computer-Aided Diagnosis Laboratory led by Dr. Ronald M. Summers. Our lab is part of the Department of Radiology and Imaging Sciences at the NIH Clinical Center.
