Radiation safety officer to retire from USA

A lot has changed in the field of radiation since David Wiik joined the University of South Alabama in 2000 as radiation safety officer. 

“Over the past 25 years, there’s been a shift in ionizing radiation usage from research labs to medical diagnosis and treatment,” Wiik said. “Some research labs still use radioactive materials, but not as many. Since medicine uses so much more ionizing radiation now than 25 years ago, there are a lot more employees that require radiation monitoring, and more emphasis is put on patient dose.”

Laser safety was not such a concern back then, either, he said. About 10 years ago, Wiik was tasked with building and managing a laser safety program as the laser safety officer. “Non-ionizing laser radiation offered a new set of challenges and learning opportunities and broadened my contact with new people I’d not met,” he said.

As Wiik prepares to retire from the Whiddon College of Medicine on Oct. 1, he says meeting and working with so many people at the university and health system have been the most rewarding part of his tenure.

A retirement celebration for Wiik is planned for Wednesday, Sept. 28, from 3 to 5 p.m. in the Medical Sciences Building third-floor multipurpose room. 

Medical students volunteer at GO Run skin screening

USA Health plastic surgeon Kimberly Donnellan, M.D., dermatologist Roberta Swain, M.D., and a group of medical students from the Whiddon College of Medicine volunteer at the GO Run.

Several medical students at the Whiddon College of Medicine gained hands-on experience in dermatology while providing free skin cancer screenings at the 15th Annual GO Run for Gynecologic Oncology on Saturday, Sept. 17.

“Offering this type of service at community events is important as we can be proactive in identifying skin cancers and treating them as early as possible,” said Chandler Hinson, a second-year medical student who helps train volunteers on the signs of common skin cancers.

Hinson and the other medical students worked alongside USA Health plastic surgeon Kimberly Donnellan, M.D., and dermatologist Roberta Swain, M.D., to screen about 40 participants at no charge. The volunteers asked standard screening questions and conducted physical exams to identify any concerning markings that needed follow-up care.

The student volunteers included Hinson, second-year medical student Hanna Bobinger, and first-year medical students Grace Sullivan, Caroline Howell, Cya Johnson and Anjali Vira.

Hinson said the event provides an opportunity to educate the community about skin cancer, the most common type of cancer in the United States. “Living in south Alabama, it is essential to do as much as we can to prevent harm from sun exposure, such as the use of sunscreen and long-sleeve, breathable clothing,” he said.

The GO Run 5K and 1-mile fun run, held on the USA campus, raises awareness and funds for GYN cancer research at the USA Health Mitchell Cancer Institute.

USA awarded $1.15 million to study impact of nicotine exposure on prostate cancer

Ajay Singh, Ph.D., professor of pathology, is studying nicotine's impact on prostate cancer.

A grant from the U.S. Department of Defense will allow researchers at the University of South Alabama and USA Health to study how exposure to nicotine, the addictive chemical in tobacco products and cigarette substitutes, impacts prostate cancer progression and therapeutic outcome.

Ajay Singh, Ph.D., professor of pathology at the Frederick P. Whiddon College of Medicine at USA, is the recipient of the $1,155,000 award and principal investigator of the project.

Tobacco use is the single most modifiable risk factor for many human diseases. According to the Centers for Disease Control and Prevention, cigarette smoking causes more than 480,000 deaths each year in the United States, including an estimated 41,000 deaths from exposure to second-hand smoke. This recognition has promoted the use of cigarette substitutes that contain nicotine to satiate addiction, while having reduced levels of other cancer-causing chemicals, Singh said. 

“Doubts about this notion, however, have been raised; and it has been shown that nicotine can, in fact, affect several steps in the development of cancer,” said Singh, who also leads the cancer biology program at the USA Health Mitchell Cancer Institute. “Our preliminary studies make strong suggestions for a pathobiological involvement of nicotine exposure in prostate cancer aggressiveness and therapy resistance.”

Researchers will use the grant funds to tease out the underlying molecular mechanisms and gather pre-clinical and clinical support for their experimental findings. Additionally, the lab will collect prostate tumor tissues from patients who smoke and those who don’t smoke, and study nicotine-induced changes in proteins of pathological relevance.  

The use of nicotine-based cigarette substitutes has increased at an alarming rate among teenagers and young adults, putting them at serious risk of developing diseases such as prostate cancer. “Our findings may generate more awareness about these health harms and collectively, with other similar findings, may push for stronger regulations about the use of nicotine-containing products,” Singh said.

Sirin Saranyutanon, Ph.D., a recent graduate of the Basic Medical Sciences Graduate Program; Srijan Aacharya, Ph.D., a postdoctoral fellow; and Mohammad Aslam Khan, Ph.D., senior research associate, played significant roles in the development of initial supporting data for the grant. Aacharya and Khan will remain an important part of the research team, Singh said. 

Additional collaborators on the project are Seema Singh, Ph.D., professor of pathology; Santanu Dasgupta, Ph.D., assistant professor of pathology; Elliot Carter, M.D., professor of pathology; Christopher Keel, D.O., associate professor and interim chair of urology; and Madhuri Mulekar, Ph.D., professor and chair of mathematics and statistics.

USA Health appoints new chief of anesthesia services

Gregory W. Bouska, M.D., M.P.A., has been named the new chief of anesthesia services for USA Health. Bouska, the current chair of the department of anesthesiology at Huntsville Hospital, will start at USA Health on Nov. 1.

“As a leader of the program in Huntsville, Dr. Bouska has been able to develop programs that further enhance the excellent quality of care provided to patients,” said John V. Marymont, M.D., M.B.A., vice president for medical affairs and dean of the Frederick P. Whiddon College of Medicine.

“As USA Health continues to expand throughout the region, Dr. Bouska’s vast experience in a large health system will be invaluable for the provision of high-quality anesthesia services throughout the organization,” said Owen Bailey, M.S.H.A., FACHE, chief executive officer of USA Health.

“Dr. Bouska will bring expertise in quality and patient experience that are key to the ongoing tremendous growth of our health system,” added Michael Chang, M.D., chief medical officer and associate vice president for medical affairs at USA Health.

Bouska earned his Bachelor of Arts in pre-med studies and a Master of Public Administration from Evergreen State College in Olympia, Washington, before earning his medical degree from the University of Washington. He completed his anesthesiology residency at Brooke Army Medical Center in Fort Sam Houston, Texas.

In addition to his positions in the private workforce, Bouska served in the Air Force National Guard for 15 years before retiring in 2003.
