Research Recruitment of Adult Survivors of Neonatal Infections: Is There a Role for Parental Consent?

Research on competent adult subjects does not require the consent of anyone beyond that of the adult subject. This case is complicated, however, because the targeted subjects were initially enrolled by their parents in a neonatal study and because the focus of the study, genital herpes simplex virus (HSV), carries significant stigma in the community. In considering the ethical issue of directly approaching the young adults for participation in this research, there are three key themes that need to be evaluated and considered: 1) the importance of the research for anticipatory guidance about the long-term impact of neonatal HSV; 2) the concerns of parents in disclosing the diagnosis; and 3) the interests of affected teens/young adults and their future partners.

Role of vitamin D in cytotoxic T lymphocyte immunity to pathogens and cancer.

The discovery of vitamin D receptor (VDR) expression in immune cells has opened up a new area of research into immunoregulation by vitamin D, a niche that is distinct from its classical role in skeletal health. Today, about three decades since this discovery, numerous cellular and molecular targets of vitamin D in the immune system have been delineated. Moreover, strong clinical associations between vitamin D status and the incidence/severity of many immune-regulated disorders (e.
