Dr. Isis notes, with some nervousness, that she has had an unanticipated, enormous response to participate in her clinical trial and wonders if the current economic climate is contributing to the interest in her project. Zuska adds that she wouldn't be surprised if that were the reason. "It seems possible to me, though, that is just an exacerbation of the situation that obtained previously - which is that poorer people have always been attracted to participation in clinical research trials either as a means of making money, or as a means of obtaining at least some sort of health care, even though clinical studies are most definitely not about providing health care to the participants," Zuska writes.
