Multiple somatic complaints, tremor, and abnormalities in motor skills and executive functions are common long-term problems among patients who have had West Nile virus infection. Patients with milder illness are just as likely as patients with more-severe illness to experience adverse outcomes.

Cancer survivors' beliefs about what causes cancer are substantially different than those of experts. Because those affected by cancer should be well informed about the causes of cancer, educational efforts are needed, especially regarding the importance of factors that can be modified to reduce cancer risk.

A mail campaign to promote mammography screening was tested with 3,887 Medicare recipients in North Dakota who had not had a mammogram in 2 1/2 years. Three types of mailings were compared: (1) a simple reminder message, (2) a reminder accompanied by a persuasive communication emphasizing personal risk, and (3) a reminder accompanied by a message tailored to the participants' chief barrier to having a mammogram. Overall, subsequent mammography rates for women in these conditions did not differ from the rate observed among women who did not receive any mailing. However, post-hoc analyses suggested that women who reported a barrier to having a mammogram were more likely to have a mammogram. Population-wide mail campaigns of the kinds tested here may be generally ineffective for Medicare recipients who are obtaining screenings infrequently. Tailoring messages may be one potentially effective intervention, if investigators can develop ways to increase responses to inquiries about barriers.
