Volunteers needed for clinical research

Fall 2007

The School of Medicine has more than 350 clinical studies ongoing at any given time. Here are a few currently in need of volunteers.

Antioxidants, omega-3 effect on heart health

People at risk for heart disease are being sought to participate in two new studies that will examine whether antioxidants and omega-3 fats help prevent heart disease.

Both studies will be led by Christopher Gardner, PhD, an assistant professor of medicine in the Stanford Prevention Research Center.

“Although antioxidants and omega-3 fats are thought to be good for you, there is little agreement among scientists—and little understanding among the general population—about how much to take and where to get those nutrients from,” Gardner said. “We will be studying the questions of ‘how much’ and ‘where from.’

Interested volunteers must fill out an online questionnaire to determine whether they qualify. The questionnaire is available at For more information, contact Project Coordinator Antonella Dewell at 650-736-8577.

Diabetes: Increasing the risk of TB?

A new study will investigate how diabetes increases a person’s vulnerability to infection with tuberculosis, or TB.

“The risk of a person with diabetes becoming ill with TB appears to be three to 11 times as high as that of someone without diabetes, and they often have more severe forms of the infection,” said Alicia Chang, MD, an infectious disease scholar. “What we still don’t know is why or how this happens.”

Researchers will examine the immune responses to the TB vaccine in people with and without type-2 diabetes.

Volunteers must be nonsmokers 30 to 65 years old, in good general health, uninfected with TB and previously unvaccinated with the TB vaccine, and born in the United States. For more information, contact Chang at 650-724-4941.
