Every year, National Colorectal (colon) Cancer Awareness Month is observed during the month of March in an effort to raise awareness of the importance for colon cancer screenings.


The recognition offers health care providers the opportunity to educate the general public about a disease that can be preventable, but can sometimes be seen as difficult for patients to discuss with their doctors.



In the spirit of education, one of Augusta University’s experts has provided some insight into the subject of colon cancer.


Dr. Asha Nayak-Kapoor is an associate professor of medicine in the Division of Hematology/Oncology in the Department of Medicine at the Medical College of Georgia at Augusta University. Nayak is certified by the American Board of Internal Medicine in Hematology and Oncology Specialties.



Q: What are the primary risk factors for colon cancer?


“Risk factors for colon cancer include: being overweight or obese, not being physically active, certain types of diets, smoking, alcohol use, being older, a personal history of colorectal polyps or colorectal cancer, a personal history of inflammatory bowel disease, a family history of colorectal cancer or adenomatous polyps, having an inherited syndrome.

Common symptoms of colorectal cancer include: bloody stool or rectal bleeding, an ongoing change in bowel habits (diarrhea, constipation, chance in stool consistency), abdominal pain or cramping, gas or persistent abdominal discomfort, you feel like your bowels are not voiding completely, weakness, fatigue, or unexplained weight loss.”



Q: How can a person protect themselves from the risks of colon cancer?


“Colon cancer is largely preventable if patients undergo screening tests, like a surveillance colonoscopy starting at 45 years or earlier depending on family history.

Many lifestyle-related factors have been linked to colorectal cancer. In fact, the links between diet, weight, and exercise and colorectal cancer risk are some of the strongest for any type of cancer.  Getting to and staying at a healthy weight may help lower your risk. A diet that's high in red meats (such as beef, pork, lamb, or liver) and processed meats (like hot dogs and some luncheon meats) raises your colorectal cancer risk.

Cooking meats at very high temperatures (frying, broiling, or grilling) creates chemicals that might raise your cancer risk. It’s not clear how much this might increase your colorectal cancer risk. Stop smoking. It is best not to drink alcohol.


People with a history of colorectal cancer in a first-degree relative (parent, sibling, or child) are at increased risk. The risk is even higher if that relative was diagnosed with cancer when they were younger than 50, or if more than one first-degree relative is affected.”


Q: It sometimes seems that colon cancer prevention is aimed more towards men compared to women, but cancer.org lists the risks at 1 in 23 (4.3%) for men and 1 in 25 (4.0%) for women. Is there a reason why perhaps a stigma about colon cancer affecting men more has been created?


“According to focus group studies, it can be seen as a taboo topic that is uncomfortable to discuss, and it is not discussed as openly in public as prostate and breast cancer screenings. It can seem embarrassing or humiliating, and can be seen as distasteful dealing with prolonged bowel preparation.”


Nayak is a member of several committees, including Onyx and Bayer Speaker Bureau for Nexavar, MCG Cancer Center Molecular Oncology Programme, and MCG Cancer Center Gastrointestinal Tumor Board Committee.

#Expert Research: “The polarization paradox: How state wealth and online media consumption affect polarization”

Augusta University's Lance Hunter, PhD, was recently published in the highly acclaimed World Affairs. His article “The polarization paradox: How state wealth and online media consumption affect polarization” highlights his expertise and insight on this very important topic, especially as America faces division and tension. Here's the abstract: Previous valuable scholarship has found that wealth inequality can affect political polarization within states. However, less is known regarding how overall levels of state wealth and online media consumption affect polarization. Thus, this study examines how state wealth and online media consumption affect polarization in 157 states from multiple regions and levels of development from 2000 to 2022. When including standard controls and controlling for potential endogeneity, the findings reveal that greater state wealth and online media consumption are associated with increased polarization. The rationale for the findings is that greater state wealth and online media consumption increase the prevalence of postmaterialist values within states that often clash with materialist values, leading to heightened polarization. These findings have important implications in considering how state wealth and online media consumption interact to influence polarization cross-nationally. Hunter is an assistant professor of political science with a background in international relations. His research focuses on how terrorist attacks influence politics in democratic countries and how political decisions within countries affect conflicts worldwide. His work has appeared in journals such as: Journal of Peace Research, Terrorism and Political Violence, Party Politics, Studies in Conflict and Terrorism, Armed Forces and Society, Conflict, Security and Development and the International Journal of Data Analysis Techniques and Strategies. Hunter teaches courses in international relations, security studies and research methods. Interested in learning more - let us help.

FAST nanotechnology unveiled at Rome Global Congress by AU scientist

Stephen Hsu, PhD, a professor at the Dental College of Georgia at Augusta University, unveiled his groundbreaking nanotechnology, known as FAST, during a keynote address at the 8th World Congress on Infectious Diseases in Rome, Italy. FAST, or Facilitated Self-Assembling Technology, offers a revolutionary way to convert compounds that are difficult to dissolve in water into stable nanoparticles. This innovation could transform drug development, viral infection prevention, hospital hygiene and more. “FAST takes a completely different approach from traditional nanotechnology,” Hsu explained. “Unlike methods that rely on polymers, metals, surfactants, fat-based carriers or complex engineering processes, FAST allows compounds to self-assemble into nanoparticles with minimal effort. This makes drugs that were once nearly impossible to formulate in water stable, effective and practical for medical and consumer use.” At the heart of this innovation is EC16, or EGCG-palmitate, a lipid-soluble compound derived from green tea. Known for its antioxidant, anticancer, anti-inflammatory and antimicrobial properties, green tea has long been studied but is challenging to use in clinical settings due to stability issues. FAST overcomes these limitations, transforming EC16 and other hydrophobic compounds into water-friendly nanoparticles. “You can’t even tell the particles are there,” said Hsu. “They look just like water. I made several different formulations in one afternoon in my lab. It’s that fast and simple.” A natural solution to global challenges Hsu’s work is the culmination of decades of research and a deeply personal journey. He credits green tea with helping him survive illness during his youth in a labor camp in China. Now, he’s turning its natural properties into cutting-edge therapies with the hope of helping more people. “I’ve been drinking green tea my entire life,” Hsu said. “Now, we’re turning its benefits into medical-grade treatments.” Supported by over $600,000 in NIH grants, Hsu’s team is developing applications like alcohol-free disinfectants and nasal sprays to prevent respiratory virus infections. One promising product is an EC16-based disinfectant that is natural, non-toxic and highly effective against tough pathogens, like norovirus and C. difficile, a bacterium that can cause severe diarrhea. “That’s a big deal for schools, hospitals and places like cruise ships, where these infections spread easily,” he said. Tackling long COVID and beyond Among FAST’s most promising applications is a nasal spray developed to prevent or treat long COVID and other respiratory illnesses. The spray, currently undergoing preclinical testing, targets viral entry points in the nasal mucosa, where infections often begin. “Our goal is to help immunocompromised patients and those with lingering symptoms like brain fog and loss of smell,” Hsu said. “We’ve already seen strong in vitro results against human coronavirus and norovirus.” In addition to nasal and topical treatments, Hsu’s team has developed oral formulations of EC16 that remain stable through the stomach’s acidic environment, critical for treating gastrointestinal viruses and potentially inflammatory bowel diseases like Crohn’s. “We found that even without direct contact with the virus, the EC16 nanoparticles taken by mouth can reduce infection,” Hsu explained. “That’s a major step forward in treatment of digestive tract viral infections.” A platform for the future of medicine FAST isn’t limited to green tea compounds. Hsu’s method can transform a wide range of hydrophobic compounds like cannabidiol, ivermectin, quercetin, procyanidin and retinoic acid, as well as hundreds of existing drugs, into nanoparticle suspensions that are stable and water-friendly. This has huge implications,” said Hsu. “Up to 90% of new drug candidates have poor water solubility and low bioavailability, which limits their effectiveness. With FAST, we can change that.” His lab is already exploring applications in Alzheimer’s research, cancer therapy, oral health and even anti-biofilm coatings to prevent hospital infections. These products, along with the nasal spray, are expected to hit the market this fall. Hsu is currently finalizing publications and preparing patent filings to protect and expand the reach of FAST. While optimistic, he remains cautious. “The results so far are phenomenal. FAST could be a new chapter in how we fight disease and deliver medicine,” Hsu said.

Augusta University named NIH Specialized Center of Research Excellence on Sex Differences

Jennifer C. Sullivan, PhD, dean of The Graduate School at Augusta University, has dedicated her research to better understand why blood pressure increases in hypertension and raising awareness to the dangers of not paying attention to heart health, particularly among women. Throughout her career, Sullivan has been continuously funded by the National Institutes of Health (NIH) and the American Heart Association since becoming a tenure-track faculty member in 2008, and now she has a chance to take her research further after securing a five-year, $7.5 million grant to have Augusta University designated as a Specialized Center of Research Excellence on Sex Differences (SCORE) by the NIH’s Office of Research on Women’s Health. It’s a distinction that places AU among 10 other leaders in research for the field, including Brigham and Women’s Hospital, Cedars-Sinai Medical Center, Emory University, Johns Hopkins University, Massachusetts General Hospital and Harvard Medical School, the Mayo Clinic, the Medical University of South Carolina, the University of Colorado and Yale University. The University of California, Los Angeles has two SCORE programs. “I’m so proud and excited for this opportunity because this has been what I have focused my research program on for my entire career, and to be able to advance it with a program like this, where we can actually build a unique program focused on an area that can make a difference, is just so much fun,” Sullivan said. “Just the fact that Augusta will be included on this list, attached to an organization of the caliber of NIH, will provide opportunities that we’ve never had before, especially for our students and younger researchers.” Sullivan’s SCORE project, “Improving awareness of women with hypertension: ROAR (Rural, Obese, At Risk),” focuses primarily on the fact that, while young women are considered “protected” from hypertension and the associated cardiovascular risk relative to age-matched men, the elimination of hypertension is projected to have a larger impact on cardiovascular disease (CVD) mortality in women. “The group of people with the highest risk of death from hypertension is in the rural South of the U.S., specifically Black women are particularly vulnerable to developing hypertension and CVD,” Sullivan said. According to Sullivan’s research and information available from the American Heart Association (AHA), approximately 19 million deaths were attributed to CVD globally in 2020, an increase of about 20% from 2010. Both Sullivan and the AHA state that cardiovascular disease remains the leading cause of death for both men and women in the United States, and that hypertension is a major modifiable risk factor for CVD. Sullivan said, “It has been suggested that eliminating hypertension would reduce CVD mortality by over 30% in men and 38% in women, but a critical barrier to limiting premature death from CVD is lack of awareness surrounding the risks of CVD. Our overall goal in this new funded project is to transform academic and community understanding of sex as a biological variable in the consideration of hypertension.” The three research projects include Sullivan’s lead project on high fat diets, a project on systemic lupus erythematosus (SLE) disproportionately affects young women led by Erin Taylor, PhD, at the University of Mississippi Medical Center, and another project looking at the role of inflammation and how immune cells are activated in SLE led by Michael Ryan, PhD, at the University of South Carlina’s School of Medicine. But there is more to SCORE than just conducting research. Each SCORE team is also responsible for a career enhancement core and a leadership administrative core. “What really sets these grants apart are the emphasis on the career enhancement and leadership administrative cores. The Career Enhancement Core is designed to be a bit open ended for each SCORE, but in talking to the NIH, what they were most excited about in our project is the community outreach piece we designed. “Our grant includes people across the entire campus, including Augusta University’s Medical College of Georgia, the College of Allied Health Sciences, the College of Education and Human Development and multiple campus partners including some of our sororities on campus and the Center for Writing Excellence,” Sullivan said. “More specifically, the COEHD is able to extend our outreach efforts to our local schools to begin educating children on the importance of screening, and our sororities are obviously connected with other chapters across the southeast which helps us spread our message, as well.” Sullivan notes that, through this portion of the project alone, there will be numerous opportunities to include students from Augusta University’s CAHS, College of Nursing, Department of Kinesiology, the Biomedical Sciences PhD program and the proposed School of Public Health. Marlo Vernon, PhD, associate professor at MCG and researcher for the Georgia Cancer Center, and Amanda Behr, chair of the Medical Illustration Program in CAHS, are also involved in various stages of the project. “The other thing the Career Enhancement Core will do is provide pilot grants to three research projects each year for early-stage investigators. We’ll also be able to fund sabbaticals for graduate students or postdocs to go someplace else and learn cutting edge techniques from other experts, so there is a lot built in that will help us support up-and-coming researchers,” Sullivan said. “We’re now part of this consortium, and they have a once-a-year, in-person meeting at the NIH offices, so we’ll go to that for the first time this year, and what’s neat about it is they’re really promoting young investigators. Each grant can bring up to eight people, the our hope is that we will have the investigators funded by the pilot projects attend next year, giving those folks the opportunity to present and talk to program officers with the NIH and develop a pipeline of investigators committed to studying women’s health and sex as a biological variable.” Sullivan is also looking to designate some of her summer graduate and undergraduate research positions to the project beginning next summer. “The Graduate School already has a summer program to support undergraduates that we will be able to piggyback off of. We have set aside five slots in that program for this that will go to students studying the sex as a biological variable, and the applications for that program, STAR, is already open,” Sullivan said. “We’re also planning a symposium in collaboration with the Physiology Department in April 2024. This is an annual event sponsored by the department, and this year they selected sex differences as the topic, so we are hoping to help increase exposure and attendance.” Looking to know more about the amazing research happening at  Augusta?
