Bench to Implementation in the Real World
Dan Colley is interviewed in a blog post for the Institue of Public Health at Washington University in St. Louis.
Former CDC executive to speak about communication and public health
Athens, Ga. – The University of Georgia’s Voices from the Vanguard series continues Feb. 17 as Glen Nowak, director of the Center for Health and Risk Communication, gives his perspective on communication as a public health tool.
The presentation, “Communication as a Public Health Tool: Difficulties, Realities, Possibilities,” takes place at 5:30 p.m. in the UGA Chapel. The lecture is free and open to the public.
Nowak will draw on his experience on the frontlines of public health, where he confronted the capabilities-and the limitations-of communication as a public health tool. He spent 14 years with the U.S. Centers for Disease Control and Prevention, where he served as the first director of communications for the National Immunization Program and then director of media relations.
During his years as the executive in charge of the CDC’s relationship with the press, he dealt with various public communication crises. The 2009 H1N1 influenza pandemic, celebrity fear mongering about vaccine safety and major shortages of essential influenza vaccine were some of the challenges he faced.
Nowak left the CDC in January 2013 to lead the Center for Health and Risk Communication at the Grady College of Journalism and Mass Communication. This was a homecoming for him, as he had been a member of the advertising and public relations faculty from 1989 to 1998. During that time he worked on a number of projects with the CDC’s Division of HIV/AIDS Prevention.
Nowak has seen crisis communication from the trenches and the ivory tower.
“As Ebola has shown, getting good, accurate information to the news media and public is often hard to do,” said Nowak. “People want and need information quickly, and that’s a challenge for doctors, scientists and public health programs. There’s many ways to make mistakes. The good news is, there’s also things that can be done to make things go better.”
Public acceptance of life-saving vaccines is one of Nowak’s passions, and he works on this both domestically and internationally. Most recently, he joined a two-year project involving the CDC and the National Vaccine Program Office in Washington, D.C. to strengthen the nation’s immunization programs and efforts. Nowak is a senior communications consultant to polio eradication efforts led by the Task Force for Global Health and World Health Organization. He has authored dozens of journal articles and book chapters and serves on the editorial review boards of Social Marketing Quarterly and the Journal of Current Issues and Research in Advertising.
The is the 10th anniversary of the Voices from the Vanguard series, a joint venture of the Grady College’s health and medical journalism program and UGA’s Center for Tropical and Emerging Global Diseases. Daniel G. Colley, director of the center and Patricia Thomas, Knight Chair of Health and Medical Journalism at the Grady College, direct the series. This lecture is the second of four and all are included on UGA’s Freshman Odyssey Seminar calendar.
Upcoming speakers in the 2015 series are:
• March 17: Sarah Schlesinger, Rockefeller University
• April 7: Maryn McKenna, author of “Superbug: The Fatal Menace of MRSA.”
A complimentary reception follows each talk at Demosthenian Hall.

UGA researchers to develop new treatment for Chagas disease
Athens, Ga. – University of Georgia researchers in collaboration with Anacor Pharmaceuticals have received a $5.3 million grant from the Wellcome Trust to develop a new drug for the treatment of Chagas disease, which they hope will be ready to enter clinical trials by 2016.
Chagas disease is caused by the parasite Trypanosoma cruzi, which spreads via a subspecies of blood-feeding insects commonly known as “kissing bugs” because they tend to bite people on the face and lips. While the disease can progress slowly, chronic infection almost inevitably results in irreparable damage to heart and digestive system tissues.
Between 10 and 20 million people, mostly in Central and South America, are infected with Trypanosoma cruzi, and Chagas disease kills more people in Latin America than any other infectious disease—including malaria, tuberculosis and HIV. An increasing number of cases are also being documented outside the normal high transmission areas, including in the U.S. and Europe.
“The two drugs commonly used to treat Chagas disease, benznidazole and nifurtimox, require a long course of therapy and have a number of serious side effects,” said Rick Tarleton, UGA Athletic Association Distinguished Research Professor of Biological Sciences in the department of cellular biology in UGA’s Franklin College of Arts and Sciences. “This combined with the fact that many isolates of the parasite are resistant to these existing drugs emphasizes the tremendous need for new treatments.”
Tarleton’s laboratory will work in partnership with Anacor, a biopharmaceutical company focused on discovering, developing and commercializing novel small molecule therapeutics derived from its boron chemistry platform.
Anacor pioneered the development of a boron-based drug class called oxaboroles, which researchers hope will serve as the foundation for a new Chagas therapy.
Boron is a naturally occurring element that is found commonly in fruits, vegetables, milk and coffee, but it is only recently that scientists have begun exploring the potential of boron-containing small molecules in drug development for a variety of infectious agents.
“These new drug classes have a lot of potential for a variety of diseases, including many of the most neglected diseases of humans,” said Tarleton, who is a member of UGA’s Center for Tropical and Emerging Global Diseases. “We have worked with Anacor to identify some potent lead compounds for use in Chagas disease, and this funding will help turn those leads into effective drugs.”

Gates grant supports UGA’s continued fight against infectious disease
Athens, Ga. – The University of Georgia Research Foundation has received an additional $710,000 from the Bill and Melinda Gates Foundation to expand its research into the elimination of schistosomiasis, a neglected tropical disease affecting millions of people throughout most of Africa and some of Asia, the Middle East and the Americas to include studies on control and elimination of intestinal worms that infect almost 2 billion people globally.
This grant adds to the more than $22 million in support awarded to UGA by the Gates Foundation since 2008, when researchers in the Schistosomiasis Consortium for Operational Research and Evaluation, or SCORE, began looking for ways to gain control of and ultimately eliminate the disease that causes more than an estimated 200,000 deaths per year in sub-Saharan Africa alone, according to the World Health Organization.
“We’ve made great progress in our understanding of this disease and what must be done to stop it,” said Dan Colley, director of UGA’s Center for Tropical and Emerging Global Diseases and principal investigator for the project. “This latest supplement will expand our research to include parallel studies on the debilitating and even more widespread soil-transmitted helminthes, round worm, whipworm and hookworms, and it will carry the project forward to 2018.”
Schistosomiasis is a parasitic disease caused by several species of worms belonging to the genus Schistosoma. The parasite’s life cycle begins when human waste containing eggs—from the worms living in a patient’s blood vessels—enters the water, whereupon the eggs hatch.
Free-swimming hatchlings then seek out and infect freshwater snails. The hatchlings mature and replicate inside the snails, eventually releasing tens of thousands of larval parasites that burrow into the skin of humans who wade, swim, bathe or wash in the water.
The infection can be treated with the drug praziquantel, but patients are frequently re-infected when they return to the water where they work or play. The soil-transmitted worms also are treatable with drugs, but reinfection rates are high due to the contaminated environment in which many people live.
“Controlling schistosomiasis and soil-transmitted worms isn’t as simple as diagnosing the disease and prescribing a treatment,” said Colley, who is a microbiologist in UGA’s Franklin College of Arts and Sciences. “We have to consider people’s behavior, their environment, social and cultural practices as well as all the medical and field data required to develop strong treatment programs.”
SCORE researchers are working with local African communities and governments to evaluate mass drug administration, snail control, diagnostic tests and sanitation and hygiene changes designed to slow or stop disease spread.
One of their first major studies, representing more than five years of fieldwork and data collection, will be ready for analysis this year. They hope these and subsequent results will ultimately reveal the right combination of techniques necessary to gain control of the disease and sustain that control until it is eliminated.
“It’s difficult to explain what a monumental task this is,” Colley said. “The project requires the hard work of dozens of partners in academia, government and non-profit organizations and hundreds of field and laboratory workers, all of whom have been invaluable in fighting these diseases that globally affect so many of those in poverty.”

CDC scientist to speak about early AIDS investigations
Athens, Ga. – “CDC, Hollywood and the early days of AIDS in the U.S.,” will be the topic of the next Voices from the Vanguard lecture at the University of Georgia.
To be held Jan. 13 at 5:30 p.m. at the UGA Chapel, the lecture will feature Harold Jaffe, associate director of science at the Centers for Disease Control. He will give a personal account of the dawn of the AIDS epidemic and share his perspective as a CDC scientist investigating the early days of the AIDS epidemic.
He was a young doctor training to be a disease detective when the first cases of the mysterious new disease showed up in the U.S. He will compare what he saw with what Hollywood captured in the HBO film, “And the Band Played On.”
“Harold Jaffe was on the front lines in the early 1980s, when alert doctors and epidemiologists recognized very odd patterns of disease among young gay men in urban areas,” said Patricia Thomas, Knight Chair in Health and Medical Journalism at UGA. “He has great stories to tell. And we can learn how it felt to see himself on screen when Randy Shilts’ historic book, ‘And the Band Played On,’ was turned into a movie.”
Jaffe served as epidemic intelligence officer at the CDC and led the first national case control study to determine risk factors for the disease and the first natural history study of HIV. He served in leadership positions in the CDC’s expanding HIV/AIDS programs and in 2001 became director of the National Center for HIV, STD and TB Prevention.
Jaffe is a member of the Institute of Medicine of the National Academies and the Infectious Diseases Society of America. He was named a Fellow of the United Kingdom Faculty of Public Health following his establishment of a new master’s degree program in Global Health Science at the University of Oxford.
He earned his medical degree from the University of California, Los Angeles, and trained in internal medicine at the UCLA Medical Center and in infectious diseases at the University of Chicago hospitals.
This marks the 10th year for the global disease lecture series sponsored by the health and medical journalism program in the Grady College of Journalism and Mass Communication and UGA’s Center for Tropical and Emerging Global Diseases. Dan Colley, director of the center, and Thomas direct the series. This lecture is the first of four and all are included on UGA’s Freshman Odyssey Seminar calendar. The next speakers are:
• Feb. 17: Glen Nowak, Grady College of Journalism and Mass Communication, UGA
• March 17: Sarah Schlesinger, Rockefeller University
• April 7: Maryn McKenna, author of “Superbug: The Fatal Menace of MRSA.”
The events are free and open to the public. A reception follows each talk at Demosthenian Hall.
