Future of Public Health: Q&A with Margo Klar, PhD Candidate at the University of Florida

file

Future of Public Health is an ongoing series focused on the emerging faces in the world of public health. We spoke with Margo Klar, MPH, a PhD candidate in the Department of Epidemiology at the University of Florida’s College of Public Health & Health Professions, about what helped lead her to the field, her Bill and Melinda Gates Foundation-funded work in maternal health, and where she hopes to go from here.

NewPublicHealth: What encouraged you to pursue a degree and career in public health?

Margo Klar: As an undergraduate at the University of California, Irvine (UCI) I majored in Chemical Engineering and worked in an environmental engineering lab. My undergraduate research focused on the effects of urban runoff on water quality, which we tracked from inland California to the ocean. During my last quarter at UCI, I took a biomedical engineering course. As a part of the class, we were asked to invent a new sleep apnea device. I really enjoyed that creative process and it opened my eyes to the fields of biomedical engineering and medicine.

After graduating, I began looking at applying to medical schools. I went back to school and took anatomy and biology prerequisites. My anatomy teacher once said, “In the United States we worry about problems with our feet, in other countries people don't have feet.” This really resonated with me. While researching medical school programs, I learned about Master of Public Health programs. I decided the MPH would be a great stepping-stone and improve my application to medical school. I was accepted into the Yale School of Public Health in the department of Environmental Health Science. Not only did I receive the training necessary to evaluate health and look for ways to improve global health, I was also able to direct my own thesis research project. I wrote my master’s thesis on an indoor cookstove improvement project for Proyecto Mirador, LLC in rural Honduras. I collected health data and examined indoor air quality improvement and reduction of firewood use as a result of cookstove replacement. This was a terrific learning experience.

NPH: You’ve received a Grand Challenges Explorations grant from the Bill and Melinda Gates Foundation to develop ceramic umbilical cord scissors. What drove you to pursue maternal and child health coming from an environmental background?

Klar: My mentor at Yale, Catherine Weikart Yeckel, PhD thought I should take a look at the Grand Challenges Explorations grant through the Gates Foundation. Essentially this funding mechanism releases a set of topics every six months to which they fund somewhere between 80 to 100 grants to the amount of $100,000 for two years of work. After the first proof of concept phase is complete, a second phase application can be submitted for up to $1 million.

Dr. Yeckel encouraged me to take a look at the maternal and child health topic. Essentially, I Googled top reasons for neonatal mortality in developing countries- neonatal tetanus and infection as a result of poor birthing hygiene and the way the umbilical cord is cut, was among the top causes. I really did not, at the time, have a strong interest in maternal and child health. I had an interest in problem solving, mainly because it’s been something, which has been a personal strength throughout my education. Thanks to my engineering background, I can look at a problem and come up with a solution to try to mitigate it. So, essentially I just applied my problem solving skills to the maternal and child health topic.

FDA Weighs in On Mobile Medical Apps

After years of deliberation, the U.S. Food and Drug Administration (FDA) has issued final guidance on the regulation of smartphone medical devices. In a nutshell, generally speaking any device used in diagnosis or treatment can’t be marketed until it’s approved by the FDA; other apps—such as calorie counters, or pedometers built into a phone—don’t need the FDA’s nod. The FDA’s criteria is how much risk an app poses for a consumer. The agency says it “intends to focus its regulatory oversight on a subset of mobile medical apps that present a greater risk to patients if they do not work as intended.”

Specifically, the FDA will focus its oversight on mobile medical apps that: 

  • Are intended to be used as an accessory to a regulated medical device—for example, an application that allows a health care professional to make a specific diagnosis by viewing a medical image from a picture archiving and communication system (PACS) on a smartphone or a mobile tablet.
  • Transform a mobile platform into a regulated medical device—for example, an application that turns a smartphone into an electrocardiography (ECG) machine to detect abnormal heart rhythms or determine whether a patient is experiencing a heart attack.

“We have worked hard to strike the right balance, reviewing only the mobile apps that has the potential to harm consumers if they do not function properly,” said Jeffrey Shuren, M.D., J.D., director of the FDA’s Center for Devices and Radiological Health. “Our mobile medical app policy provides app developers with the clarity needed to support the continued development of these important products.”

While the final guidelines were only just released, FDA has cleared 100 mobile medical apps for marketing in the last few years, and 40 of those were just in the last two years.

Synim Rivers, an FDA spokesman, answered questions for NewPublicHealth about the final guidance on mobile medical apps.

Stroke Awareness Month: There's an App for That, Too

file F.A.S.T. app alerts users to stroke symptoms and a call to action

May is Stroke Awareness Month, a good time to bump up the percentage of Americans who recognize the most common symptoms of a stroke from only 38 percent, according to a Centers for Disease Control and Prevention (CDC) survey. Speedily identifying stroke symptoms and calling for an ambulance is essential because people who get to an emergency room for treatment within three hours are healthier three months later than people for whom stroke care was delayed, according to the CDC.

New this year to help increase symptom awareness is a free smartphone app from the American Heart Association/American Stroke Association called F.A.S.T. The acronym stands for common stroke symptoms and a critical call to action: Face drooping; Arm weakness; Speech difficulty; and Time to call 9-1-1. The app also includes a link to additional symptoms that bystanders and caregivers can access and a 9-1-1 button to call an ambulance. Using the 9-1-1 button saves time by not having to back out of the app to dial the number manually. And using the button also generates an automatic time stamp, which gives emergency room staff a good indication of when symptoms began. Some treatments can only be given within a specific time window.

Surgeon General's Healthy Apps Challenge: Winners Announced

sq_healthyapp_badge

Winners of the Surgeon General’s Healthy App Challenge were announced late last week, after the challenge launched earlier this winter at the mHealth Summit. The goal of the challenge was to highlight the ability of innovative new technologies to provide health information tailored to the needs of the user, and empower the public to regularly engage in and enjoy health-promoting behaviors.

>>Read more about the value of challenges to promote innovation from HHS Chief Technology Officer, Todd Park.

"I've been delighted with the response to the challenge," said Surgeon General Regina Benjamin, MD, MPH. "The winning apps will help many Americans to have fun while getting fit and healthy."

The applications were assessed by a team of judges that included figure skater Michelle Kwan and Shellie Pfohl, Executive Director of the President’s Council on Fitness, Sports & Nutrition. Criteria used to assess the apps included:

  • usefulness
  • innovativeness
  • quality of evidence supporting the app’s approach to healthy behaviors
  • usability
  • ability to tailor and download personal data
  • the “fun” factor

In addition, all the apps submitted for review had to be available on readily accessible platforms, free for consumer use and fully operational without the purchase of additional products.

And the winners are…
