The Anesthesiology neuroscience research program studies how consciousness works, particularly when patients are under anesthesia or sleeping naturally. Subimal Datta, PhD, Professor of Anesthesiology, has been researching the link between sleep and neurological disorders.
He is recognized as one of the world's leading sleep experts, with studies on insomnia, addiction, depression and anxiety disorders, including PTSD — all done through the lens of sleep.
Sleep is one of the best windows for studying the brain, and studies have shown that sleep carries with it a number of positive functions. Dr. Datta is focusing on how the brain regulates a certain sleep stage, called REM, or dreaming sleep. Particularly of interest is how the brain processes different types of memory during this stage.
"We encode information as we go through the day, and that information goes into short-term memory," Dr. Datta said. "If we don't sleep, the information is lost. It will simply disappear."
But if we sleep long enough to achieve the dream state, our brain is able to place that information in long-term storage.
"Sleep has four distinct stages of memory processing," said Dr. Datta. "Each stage does something different." In the first stage (N 2 sleep stage), the brain sorts the information into two piles, one to discard and one to keep. In the second stage (delta sleep), about 90 percent of the information is thrown away — typically information you already know. In the third stage (transition between non-REM and REM sleep), the brain strengthens the memories, and in the fourth (REM sleep), it puts memories into long-term storage.
Dr. Datta compares it to putting away your groceries. "After you shop, you have two choices. You can put the bags in the kitchen, and if you need something later, go through all the bags to find it.
"But if you have a system, where frozen foods go in the freezer, cold ones in the fridge and canned goods in the cabinets, you can easily find whatever you need. This is like the brain sorting memories for long-term storage."
In addition to the correlation between sleep and long-term memory, the research program is also looking deeper at the link between sleep and psychiatric disorders. Because the brain uses the same neurochemicals and processes in both experiences, if they can understand sleep, they may also isolate the source of stress, anxiety and other psychological issues.
"A lack of sleep can trigger early onset of all sorts of psychological disorders," said Dr. Datta. For example, if someone is genetically predisposed to Alzheimer's, Huntington's or Parkinson's, a consistent lack of sleep (fewer than six hours a night for 20 years), can trigger the disease 10 years earlier. Diabetes, hypertension and heart disease can also be triggered by deficient sleep.
Dr. Datta notes that, if you can't sleep a full six hours at a time, taking a nap during the day helps. "If you sleep four hours at night and two during the day," he said, "it's not equal but it's much better than just getting four."
Dr. Datta will continue his innovative research with the Neuroscience Research Program through a generous grant from the National Institutes of Health.
"A lot of progress has been made in understanding sleep and the brain over the last 50 years," he said. "While we may never know all there is to know about it, we continue to do what we can to understand it better."
A summer research opportunity turned into a year-long research position and helped change the course of an aspiring doctor's career goals.
Adrianna Eder participated in the 2015 I. Reid Collmann, MD, Research Endowment program, learning about basic science research through Surgery's Division of Trauma and Critical Care under the direction of Michael Karlstad, PhD, whose research is supported by National Institutes of Health funding. The goal of the Collmann program is to equip medical students with a solid foundation in research so that they can see firsthand how basic science research affects patient care.
Eder said that as a Collmann fellow, she was able to see physiology in action, investigating the factors that affect pancreatic beta cell function (the pancreatic cells that control blood glucose), ultimately helping patients with diabetes.
"Clinical relevance gives this research special significance, and each experiment was designed with the diabetic patient in mind," Eder said. "My experience as a Collmann fellow solidified my interest in both clinical medicine and basic research."
After the summer program concluded, Eder continued working in Dr. Karlstad's lab as a research assistant and was awarded a competitive travel grant by the Shock Society to attend the 39th Annual Conference on Shock in June for her first-authored abstract, "Atmospheric Plasma: A Novel Approach to Wound Disinfection in a Murine Model," co-authored by Molly Wintenberg, Alan Wintenberg, Kim Wintenberg, Jason Collier, Eric Karlstad, Preston Mitchell, Patricia Coan and Michael Karlstad.
This fall, Eder will begin medical school at the UT Health Science Center in Memphis, with the hopes of pursuing a career in academic medicine.
She said, "Physician-scientists impact more than the quality of their own patients' lives; they change the way medicine is practiced by all physicians, and that is why I want to incorporate research into my clinical career."
Eder's career path wasn't always obvious to her. Before she discovered her passion for research, she planned to pursue a dual MD/MBA degree because she was interested in healthcare management. However, before she ever envisioned herself as a doctor, she wanted to heal people through nursing. She said, "I realized I wanted an education that would allow me to contribute to integrated medicine and improved patient care. My interests were fashioned into an Integrated Studies degree, with concentrations in biology, pre-medicine and accounting. For better or worse, medicine and business are becoming increasingly integrated, so my coursework was carefully designed to prepare me for a career in healthcare as the kind of physician-leader I wanted to be."
Then, Eder worked in a research lab at UT Chattanooga as part of her senior thesis project and received an Honorable Mention for the Barry Goldwater Scholarship, the premier undergraduate scholarship for students doing research in the sciences.
"I learned the importance of understanding why, in addition to knowing what," Eder said. "I found myself excited about the clinical relevance of the skills I acquired in the lab, and it was then that my interest shifted from the integration of medicine and business to the integration of medicine and basic research."
Eder said the Collmann experience solidified her new career path as a physician in academic medicine, and she learned that working in a lab allows her to apply business management skills, too. "Dr. Karlstad is an amazing mentor. I learned not only about research but also about the resources needed to keep a lab running. He's extremely business savvy."

The University of Tennessee Mechanical, Aerospace, and Biomedical Engineering (MABE) Department held its first Senior Design Expo to showcase senior design projects from more than 30 teams. First place was awarded to a team of students known as the UT Clippers who were collaboratively mentored by Michael Walsh, MD, Director of Neuro-Oncology, and Dustin Osborne, PhD, Director of the Molecular Imaging and Translational Research Program at the UT Graduate School of Medicine and Jeff Reinbolt, PhD, MABE Associate Professor. Their project involved the creation of a prototype modular aneurysm simulation model that could allow physicians to practice aneurysm clipping, a surgery performed to treat an aneurysm when the artery wall leaks or ruptures, prior to the actual procedure. This team was one of two teams mentored by Dr. Walsh and Dr. Osborne this year.
Other projects presented at the Senior Design Expo included a virtual reality forklift training system; a foot-pedaled, portable vaccine refrigerator that can be carried on a person's back; a detachable percutaneous endoscopic gastrostomy tube; and an aircraft fuselage cleaning system that can reduce time and injury.
All teams displayed posters, prototypes and gave presentations during the expo. Cash prizes were given to the top three posters, and the crowd, which included fellow classmates and company sponsors, had the opportunity to vote on their favorite project in the people's choice award competition.
Fifteen industrial sponsors, including Boeing, DENSO, Eastman, Lexmark, and the National Institute of Health, funded the senior design projects. Learn more about the innaugural Senior Design Expo.
Mitchell Goldman, MD, Assistant Dean for Research and retired vascular surgeon, was presented with a special puppet known as Alex who was used to educate children and families about organ and tissue donation and transplantation through Kids on the Block, a troupe of education puppets. Trudy Dreyer, Alex’s volunteer puppeteer, presented Alex to Dr. Goldman upon her and Alex’s retirement from the organization.
Kids on the Block uses puppets to help children understand differences in one another and teach children how to protect themselves in difficult situations. According to its website, the organization was formed in response to a 1977 law that required children with disabilities to be educated in the least restrictive environment, which typically meant children were included in classrooms with non-disabled peers. The first puppet created was known as Mark Riley who represented a child with cerebral palsy.
To educate children on organ donation and transplantation, The University of Tennessee Medical Center's Center for Transplant Services secured a grant more than 20 years ago that Kids on the Block used to create Alex and two other puppets who told a story about a heart transplant. Alex's character was Alex Landry, an 11 year old who received a “new” heart because he had a condition known as cardiomyopathy. Another puppet, Melody James, was the sister of Darryll, whose heart Alex received, so Melody told about the donor perspective. Michael Riley was an 11 year old who was curious about both organ donation and transplants, so he helped to narrate Alex and Melody’s story.
Dreyer said she chose to be Alex’s puppeteer because her husband had had a heart transplant at Hunter Holmes McGuire VA Medical Center, where Dr. Goldman's work helped found the nation's first heart transplant program. When she and Alex retired from the Kids on the Block program, she wanted to give Alex to Dr. Goldman because he was instrumental in guiding her husband toward transplantation, and she thought Alex should go to someone who did transplants.

Integrity plays an important role in healing, but sometimes what is "right" is unclear. Annette Mendola, PhD, Chief of the Division of Clinical Ethics and Assistant Professor of Medicine, initiated a program at The University of Tennessee Medical Center known as Ethics Case Rounds to help guide clinical staff through ethically difficult situations.
Dr. Mendola said, "The Ethics Consult service we offer to patients, their families and our healthcare teams typically comes into play when everyone is trying to do the right thing, but it's hard to say what the right thing is. For example, when patients do not have decision-making capacity for treatment, and family members disagree about what the patient would want done, the goals of care are not clear for the physician." Other common situations include when patients or family members are requesting treatment the physician believes would be harmful, or when patients may not fully understand their options.
Each month, Dr. Mendola presents a situation based on a real case, with identifying information removed, and invites a panel of team members who were key to the case to help lead discussions. The panel may include the attending physician, key nurses and residents, occupational or physical or respiratory therapists, dietitians, case management representatives, or other pertinent non-clinical staff. Then, the discussion is open among all who attend, which is a diverse mix of clinical and non-clinical staff from all specialties, with the goal of understanding one another's perspectives and developing a shared understanding of how to handle similar situations.
Doctors remember one case in particular that discussed whether removing life support should also include inactivating the patient's pace maker. The patient's family requested deactivation as part of end-of-life care, but none of the cardiologists would agree, saying that deactivation would be unethical.
Mark Rasnake, MD, Assistant Professor and Internal Medicine Residency Program Director, explained, "For a cardiologist to inactivate the pacemaker, there would be a significant change. The patient would pass immediately. This case highlighted the somewhat gray zone between standard end-of-life/comfort care versus euthanasia. Many in the room felt that deactivating artificial devices (pacemakers included) did not constitute euthanasia. The contrary opinion, that fully implanted devices were now a ‘part of the patient' is one that has significant weight. Intentionally deactivating such devices would be essentially harming a patient under such a viewpoint. It is a very thorny issue."
While Ethics Case Rounds was initiated as a learning tool for physicians and nurses, Rasnake recognized the program as a valuable teaching tool for residents, and participation in Ethics Case Rounds has become a core part of the Internal Medicine Residency curriculum.
Dr. Rasnake said, "The program has provided me a significant amount of benefit personally, and it has provided a wonderful educational venue for my residents. They seem to feel it is a safe space for them to discuss the emotional impact some cases have on them, and they get to see how others react under similar circumstances. Dr. Mendola is to be commended for bringing this program to the medical center."
Resident Sachin Amin, MD, already sees the benefit Ethics Case Rounds will have on his career. "It is a course that not many other residency programs provide," he said. "Once we finish residency, we will be seeing many more patients on a daily basis, and we will be surrounded by ethical conflicts. Having a good base of ethical principles will help us make decisions in the patient's best interest."
Ethics Case Rounds meets on the fourth Thursday of each month in Wood Auditorium and is open to team members at the medical center.
Patrick McFarland, MD, Anesthesiology Resident, has been selected as the Tennessee Medical Association Resident and Fellow Section Governing Council Chair for 2016-2017.

Other award recipients from UT College of Medicine were Chris R. Collins, MD; Patrick R. Higgins, DO; Michele McAmis, MD; and Catherine Watson, MD, from the Memphis campus; and Amit S. Shah, MD, from the Chattanooga campus. Award recipients were honored at the Student Clinician's Ceremony in Memphis and will be inducted as members to the Arnold P. Gold Humanism Honor Society.
Janet Purkey, MD, FACP, Associate Professor and Medical Student Clerkship Director in Medicine, was awarded the 2016 Outstanding Physician and Teacher award by the Class of 2017 College of Medicine, University of Tennessee Health Science Center, Memphis, Tennessee. She was selected by the class based on her enthusiasm and passion for teaching medical students and excellence in patient care.
She was invited to speak to the Class of 2018 as the rising third-year students began their clinical rotations on May 2. Acting as an ambassador for physicians, she encouraged the incoming students giving examples of the challenges and unique learning experiences found only by direct patient care.
Dr. Purkey said, "Respect for each specialty is critical as we rely on pathologist and radiologist being the best physician as well as each surgeon, internist, gynecologist and subspecialist. Our patients rely on us to provide the best care possible. Focus on the things that are worthwhile. Live below your means to help you get out of debt from school."
She also encouraged them to be a team player and respect their colleagues. "Get to know all the team including not just the nurses, but the therapists, housekeepers, case managers and transport personnel."
The University of Tennessee Medical Center announced that University Bariatric Center has been re-accredited for the third time as a comprehensive center under the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®), a joint program of the American College of Surgeons (ACS) and the American Society for Metabolic and Bariatric Surgery (ASMBS).
"Our center has a strong team, and together we are able to address the complex needs of people with the disease of obesity," said Gregory Mancini, MD, medical director for the University Bariatric Center. "Our multidisciplinary team consists of surgeons, dietitians, exercise specialists and health educators that that provide compassionate care with pre-surgery counseling, nutritional education, after-surgery information, and counseling. As a team, we seek continuous improvement to enhance the structure, process and outcomes of our center."
The MBSAQIP Standards, outlined in the Resources for Optimal Care of the Metabolic and Bariatric Surgery Patient 2014 ensure that bariatric surgical patients receive a multidisciplinary program, not just a surgical procedure, which improves patient outcomes and long-term success. The accredited center offers preoperative and postoperative care designed specifically for their severely obese patients.
To earn the MBSAQIP designation, the University Bariatric Center met essential criteria for staffing, training and facility infrastructure and protocols for care, ensuring its ability to support patients with severe obesity. The center also participates in a national data registry that yields semiannual reports on the quality of its processes and outcomes, identifying opportunities for continuous quality improvement. The standards are specified in the MBSAQIP Resources for Optimal Care of the Metabolic and Bariatric Surgery Patient 2014, published by the ACS and ASMBS.
