Student-Run Equal Access Birmingham Opens Its Own Clinic
By Matt Windsor and Meghan Davis
Since 2007, Wednesday nights for many UAB medical students have meant a short drive to the M-POWER Ministries health clinic in Birmingham’s Avondale neighborhood. Under the supervision of faculty physicians, the doctors-in-training provide acute care for the medically underserved patients at M-POWER’s free walk-in clinic. But they wanted to do more.
Demand for slots had grown so strong that many students could only take part a few times per year. So the students, who have run their own organization, known as Equal Access Birmingham (EAB), since 2005, decided to open their own clinic, closer to campus.
In November 2012, with money earned from a School of Medicine variety night known as the Best Medicine Show, plus matching funds from then-dean Ray L. Watts, M.D., EAB completed its mission. The new student-run clinic, just a few blocks from campus at the Church of the Reconciler, provides long-term care to underserved patients in the Jefferson County Housing Authority Shelter Care Plus program. EAB also will continue to staff the M-POWER clinic.
Local Heroes Help Turn Dental Problems into Solutions
By Dale Short
Some vexing health questions can be answered with a new machine or dazzling technical insight. Others require a simpler tool: time.
“How can you tell whether a tooth needs filling immediately or not?” says UAB alumna Kaye Shaw, D.M.D., who practices family dentistry in the town of Fairhope on Alabama’s Gulf Coast. “The research might involve observing a tooth closely for anywhere from six months to two years.”
Shaw is helping to answer dental conundrums just like that one. She is one of many UAB dental alumni who are collaborating on a massive research project made possible by the largest grant in the university’s history. The program, known as the National Dental Practice-Based Network, is a seven-year, $66.8-million program connecting the National Institute of Dental and Craniofacial Research—a part of the National Institutes of Health—with a network of local dentists in six regions from Portland, Oregon, to Gainesville, Florida.
“We hope to improve the nation’s oral health by improving the knowledge base for clinical decision-making and moving the latest evidence into routine care,” says principal investigator Gregg Gilbert, D.D.S., M.B.A., professor and chair of the UAB Department of General Dental Sciences. The network, Gilbert explains, is “a unique investigative union of real-world practicing dentists and academic scientists.” Practicing dentists suggest problems—and provide data and observations; UAB researchers investigate solutions and communicate these back to the practitioners. Research topics already in the works include everything from “Persistent Pain and Root Canal Therapy” to “Assessing Outcomes of Cracked Teeth.”
Love and Loss on the Ice
By Matt Windsor
In his new book, Lost Antarctica, polar biologist Jim McClintock, Ph.D., offers plenty of reasons to be concerned about the fate of the frozen continent: a few trillion, at least.
That’s the approximate number of sea butterflies currently floating in the chilly waters of the Southern Ocean. The tiny, shelled creatures serve as the base for an intricate food chain that extends upward to the mighty blue whale. Hundreds of species depend on the sea butterfly, but it is under assault on a massive scale. Rising levels of atmospheric carbon dioxide, transferred to the polar oceans by complex climate effects and simple chemistry, are making the sea butterfly’s home waters more acidic.
When the pH reaches a critical point, it will dissolve the animals’ protective shells—killing them and risking the collapse of an entire ecosystem. Acid seas are the “other CO2 problem,” McClintock says—one that, unlike the problem of CO2 emissions in the atmosphere, has received little media attention.
Lost Antarctica offers a host of other reasons why we need to sweat the seemingly small stuff now occurring in this icy world. Combining the latest scientific data with personal observations from two decades of Antarctic research, McClintock lays bare the intricate inner workings of his beloved continent. In Antarctica, he explains, everything from microscopic phytoplankton to state-sized ice shelves is interconnected—and under threat.

UAB Magazine: Your book describes many worrying changes in Antarctica. Which is the most apparent when you visit?
McClintock: The most obvious to me are the changes in the ice, especially in the Antarctic Peninsula [the section of the continent closest to South America]. The annual sea ice along the peninsula has receded about 40 percent in the last 30 years. And that has had a major effect on a community that surrounds Palmer Station. There has been a large colony of Adelie penguins on Torgersen Island for 700 years, but in the last 30, it has dwindled rapidly. In the book, I call it a “ghost rookery.” The Adelies use the sea ice to reach their feeding grounds. But as the ice has shrunk, they have had to swim farther and farther to reach those grounds. These animals are living right on the edge of their energy budgets anyway, and they can’t make it. Then there’s the warming of the air, which makes it more humid and increases snowfall. The Adelies are genetically programmed to show up on Torgersen at the same time every year, but now they are often caught up in unseasonably late snowstorms while nesting their eggs. And when the snow melts, the eggs drown.
UAB Magazine: After 20 trips to Antarctica, what keeps you coming back?
McClintock: Several things. Antarctica’s natural beauty is just breathtaking. You look off in the distance and think you can reach out and touch a mountain range, and it’s actually hundreds of miles away. Also, Antarctica is one of the most fabulous places on our planet to study marine biology. When you dive under the ice, the seafloor is covered with life—just as much as you would find in the Great Barrier Reef in Australia. There are so many intriguing scientific questions about the marine life and how it’s adapted to such a unique environment. I feel very lucky to get to work there.
UAB Magazine: Considering you named your book Lost Antarctica, do you have any hope that the continent can be saved?
McClintock: We haven’t yet lost the continent, but its marine life is genuinely being threatened. There is hope that remediations that will reduce the production of greenhouse gases will slow down what is happening. But the dramatic changes being witnessed are a wake-up call. I’m not saying we need to give up our cars tomorrow. But we do need to start thinking rationally about where we can make accommodations in energy conservation.

In December I got the chance to lead a group on a philanthropic “Climate Change Challenge” expedition cruise for Abercrombie and Kent to Antarctica. With All Seasons Travel here in Birmingham handling the cruise bookings and in my role as a professor of Polar and Marine Biology at UAB, I took a group of 16 from Birmingham, which makes 100 people from this city that I’ve been able to take down there over the past six years. Many of them are business leaders and other very influential people in our community. It’s life-impacting. They come back and are ambassadors for Antarctica.
UAB Magazine: Do you ever see yourself retiring from Antarctic expeditions?
McClintock: Once you’ve been, getting back to Antarctica becomes a vocation in and of itself. I don’t see this amazing continent leaving my horizon until I physically can’t go. It’s a love affair, really, and I’m not ready to give it up.
James McClintock is the UAB Endowed University Professor of Polar and Marine Biology. You can purchase a copy of Lost Antarctica at any bookstore or online. The book’s website is www.lostantarctica.com.
McClintock on what he couldn’t live without on a polar expedition.
I’ve got it down to five “C”s. First is communication. When I was a graduate student on my first trip in 1982, all we had were Western Union telegrams. And at $3 a word, I couldn’t say much. Now I have an Internet-connected phone in my office and another beside my bed. To be able to talk to my wife and family whenever I need to is a wonderful thing.
You can’t go without a camera. You’ll never be able to accurately capture that amazing landscape with a camera, but you have to have one. You can’t walk ashore among 100,000 penguins without a camera—you’d go catatonic.
Camaraderie is vital. You’ve left your family behind, so you need that sense of connection to others. And I’ve always experienced a wonderful camaraderie, not only within my research station “family” but in many other settings. A ship pulls in from Argentina or Chile, and you get to share a glass of wine with the crew and talk about your work. The same thing occurs when you visit another country’s station. It transcends gender and age, too.
Warm clothing, of course, is another must. Despite climate warming, you still need to wear a jacket when you go outside! Several layers, in fact.
Finally, you need a good chef. Working in an Antarctic station is a lot like going to sea. Food is vital to the psychology of the experience; you have serious consequences to morale if you don’t have good food. We aren’t eating steak and lobster every night by any means, but the food has always been good. We even get fresh fruit and vegetables—what we call “freshies”—regularly, but it wasn’t always like that. Now, at Palmer Station, the ships come about once a month, at least.
When a ship arrives, everyone drops what they’re doing and goes down to the “freshies line.” We lift boxes of avocados, grapefruit, etc., and pass them from person to person until they’re safely in the kitchen.
When I worked at McMurdo Station in the 1980s and ’90s, we’d have periods with no freshies. I remember a sign over the lettuce, which had been grown in a greenhouse at the station, saying that each person was entitled to one leaf. Thankfully, that’s no longer the case.
Educating Truckers on the Go
By Todd Dills
When UAB nurse practitioner Karen Heaton, Ph.D., met her husband, a long-haul owner-operator, she discovered that the nation’s truckers carry a host of unmet health needs along with their cargo. In particular, “I was struck when I read that individuals who are sleep-deprived and driving have the same levels of impairment as those who are intoxicated,” Heaton says.
Now Heaton, an assistant professor in the UAB School of Nursing, is testing an online intervention program focusing on sleep and fatigue management among the nation’s truck drivers. She has been visiting industry trade shows and reaching out to trucking companies and associations to recruit drivers to participate in the study, which is funded by the National Institute of Occupational Safety and Health.
Heaton’s goal is to arm truck drivers with the information they need to recognize the importance of sleep for safety, well-being, and, ultimately, baseline human health. If the online model proves to be effective in reinforcing the basics of sleep among participants and encouraging them to modify their behavior, Heaton hopes that trucking companies will add it to driver-safety training. The program could even become part of the first health-related requirements for Federal Motor Carrier Safety Administration (FMCSA)-regulated training, something every new long-haul driver would take in the interest of public safety.
