VCU School of Nursing receives to study effect of yoga on depression during pregnancy

The National Institutes of Health recently awarded a grant to the Virginia Commonwealth University School of Nursing for a pilot study that will examine how motivational interviewing and prenatal yoga might reduce or prevent depression during and after pregnancy.

Patricia Kinser, an assistant professor in the Department of Family and Community Health Nursing, received the two-year, $456,579 grant for her project “Self-Management of Chronic Depressive Symptoms in Pregnancy.”

“Nearly 20 percent of pregnant women experience depressive symptoms during pregnancy and 13 percent experience chronic, recurrent symptoms,” said Kinser, whose research focuses on stress and depression in women and their families.

Research delves into women’s, men’s differing reactions to mental stress

By Marilyn J. Shaw

More women than men die from heart disease each year. This suggests that the cardiovascular system of men and women functions differently.

“Our lab has been interested in examining whether or not the response to stress, in particular mental stress,  is different, which might be one explanation why women die at a higher rate,” said Edmund O. Acevedo, Ph.D., chair and professor of the Department of Health and Human Performance in the Virginia Commonwealth University School of Education.

In ongoing research, Acevedo and his team introduced human subjects to lab-induced stressors, including computer tasks, mental arithmetic and the Stroop color word task.

“They’re simple tasks anybody can do,” he explained. Yet men and women react differently to the mental stress. “In males, these tasks elicit a greater blood pressure response. We call that a vascular reaction. In females, a greater increase in heart rate, which is a cardiac response.”

To better understand the body’s reaction, the researchers draw blood periodically from their subjects and examine it in an attempt to distinguish unique inflammatory markers that help to explain the difference in cardiovascular response.

Acevedo also is interested in obesity and physical activity and the impact of pro-inflammatory response.

“Ours was the first lab to demonstrate pro-inflammatory response linked to BMI (body mass index),” Acevedo said. “Our intention is a greater understanding of how obesity and physical activity ameliorate or attenuate cardiac and vascular reactions. The lab has completed studies in lean and obese males, and we hope to extend our data collection on females,” he said. The VCU Presidential Research Initiatives Program and VCU School of Nursing are providing funding. Principal investigator for the male subjects is assistant professor R. Lee Franco, Ph.D., in the School of Education, and for the female subjects is associate professor Dr. Kyungeh An, Ph.D., in the School of Nursing.

In the past, Acevedo’s research broadly looked into human performance, including physiological reactions to the stress of exercise. More recently, his approach has evolved into studies that can have an impact on more people, leading him to address health issues. The gender differences in heart disease rates and current treatment approaches, led him into this realm.

“As a scientist, (the gender difference in heart disease rates) is an interesting, intriguing question. The clinical paradigms were developed for males. How come we do not do something different for women? We don’t understand the differences well enough,”  he said.

“We’re adding to the literature of what might be happening. And with that knowledge, someone might eventually develop novel approaches.”

Gates Foundation supports HIV researchers

VCU is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.

With the $100,000 grant, researchers from the VCU Institute for Women’s HealthVCU schools of MedicineNursing, and World Studies in the VCU College of Humanities and Sciences, will work with community partners in Ségou, Mali, to pursue an innovative global health and development research project, titled “Reducing Harmful Inflammation and Attenuating Immune System Deterioration in HIV-Infected Malian Women.”

“This award will help us determine how certain beneficial intestinal bacteria in HIV-infected women in Africa relate to immune system function,” said principal investigator Daniel Nixon, D.O., Ph.D., director of the VCU HIV Center and associate professor in the Department of Internal Medicine. Patricia Cummins, Ph.D., professor of French in the VCU School of World Studies, and Saba Masho, M.D., associate professor of epidemiology and community health in the VCU School of Medicine, serve as co-principal investigators of the study.
