This edition includes chapters on managed care and medical genetics, as well as an expanded chapter on virtue and decision making. It updates accounts of controversies, including late-term abortion, cloning, germ-line genetic research, the human genome project, brain death, non-heart beating organ donors, and physician-assisted suicide. Case studies, drawn from landmark public cases, illustrate such issues as medical futility, genetic screening, AIDS research, managed-care mix-ups, and the ignoring of patients' wishes by doctors.
