The failure of at least seven medical researchers to disclose their financial ties to the makers of antidepressants prompted The Journal of the American Medical Association to toughen its conflict-of-interest policy. It also issued a correction of an article those researchers wrote warning of the potential dangers to pregnant women who stop using the drugs. The article, published in February, reported that pregnant women who discontinued their use of antidepressants greatly increased their risk of relapsing into depression. The authors, including several prominent psychiatrists from Massachusetts General Hospital, Emory University, and the University of California at Los Angeles, failed to mention that they had served as paid consultants and lecturers for the manufacturers of antidepressant drugs. That omission prompted Adam C. Urato, now an assistant professor of maternal-fetal medicine at the University of South Florida, to write a letter to the editor asking the journal to inform readers about the potential conflicts of interest.
