Death's legal definition must be responsive to advances in technology, and it must delineate between life and death. But where to draw the line is difficult to determine. Death's current legal definition requires irreversible cessation of cardiorespiratory function or irreversible cessation of all brain function. But technology can often restore some brain functions without restoring consciousness, so brain death is often diagnosed without the irreversibility requirement being met. This article argues that the law should be updated to require permanent cessation, not irreversible cessation and that medicine should be transparent about what permanent means.Brain death differs from traditional circulatory death, and understanding how it differs is important. Public awareness of brain death is based largely on inaccurate media representations, common examples of which are described here. The purpose of this article is to motivate lay understanding of brain death by tracing key moments in the history of how we've come to define and recognize brain death as death. This article also considers criticisms of brain death and rebuttals to those criticisms.Mismatch between whole-brain death criteria embedded in statutes and accepted tests physicians use to diagnose brain death have clinical and ethical implications that could undermine public trust in death pronouncements. We consider merits and drawbacks of 4 ways to address this problem.Physicians have a long-standing obligation to consider social implications of their practice and its potential influences on health policy. One example of a practice's influence on policy is determining death by neurologic criteria. By lobbying policymakers, maintaining their diagnostic skills, participating in national medical societies, and contributing to robust discourse, physicians can positively influence practice and policy about death determination by neurologic criteria.Since it was proposed in 1980, the Uniform Determination of Death Act has provided the legal basis for determination of death by neurological criteria. The act contains language that allows for acceptable medical standards to be used to determine death. Since 1995, the American Academy of Neurology has provided guidelines for brain death determination (revised in 2010), but nationwide adherence to these guidelines has been incomplete. This variability could lead to misdiagnosis and erosion of public trust in this important medical practice. Physicians must work together as a profession to push for uniformity and accuracy in death diagnosis.Death determination is fraught with clinical, cultural, and ethics questions. This article considers relevant history that informs the AMA Code of Medical Ethics opinions about neurological criteria for death.The legal basis of what's known as the "dead donor rule" (DDR), which requires that donors must be dead according to legal criteria, is rooted in physicians' fears of civil and criminal liability for participating in organ retrieval and donation. This article suggests that one reason to revisit the DDR is to help illuminate possible legal ways to retrieve and donate organs. Specifically, this article considers one of these medically justifiable homicide, which is legally and ethically distinct from murder and wrongful death.It is critical for brain death diagnosis to be accurate. Although standardized guidelines and institutional protocols for brain death determination exist, for many physicians, lack of understanding about brain death leads to confusion and muddles interactions with patients' loved ones at the end of life. Using a case-based approach, this article demonstrates what tends to go wrong in erroneous brain death diagnoses and clarifies what physicians and educators should do to help avoid these errors.This article considers whether and when a physician is obligated to offer life support to the point of fetal viability to a patient who is brain dead and pregnant. see more Lack of ethical, legal, and clinical consensus about best practice in managing this kind of case; a poor clinical evidence base; and the fact that offering life support violates the patient's autonomy and human dignity, as expressed in her advance directive, are sources of ethical, legal, and clinical complexity analyzed here.Two commentaries respond to a case. Each considers religious or cultural values that sometimes conflict with medical standards of practice or law. These conflicts frequently occur at the end of life when stress and tensions are high and, if not handled carefully, can escalate and cause tremendous pain.Two commentaries respond to a case about apnea testing to confirm death by neurologic criteria.Spironucleus muris is an intestinal protozoal pathogen that can infect various species of rodents. The infection can have a wide range of clinical presentations, from no signs of disease to death. In addition, this pathogen can adversely affect research results, especially immunologic and gastrointestinal studies. For these reasons, institutions may exclude Spironucleus muris. However, despite rigorous efforts to keep this pathogen out, it can be common in rodent colonies. The current recommended approach to eradicating this pathogen is by testing and culling positive animals. A similar organism, Giardia muris, has been effectively eliminated by using chemotherapeutics. Therefore, the objective of this study was to determine whether S. muris is also susceptible to chemotherapeutics. Naturally infected mice were randomized to treatment groups after confirmation of positive infection via PCR. Mice received either metronidazole, fenbendazole, a combination of metronidazole-fenbendazole, or acidified water (control) treatments for a period of 4 wk. Each week fecal testing of S. muris was performed via PCR to evaluate the effectiveness of the treatments. At the end of the 4 wk period, mice were euthanized via CO₂ inhalation and segments of the proximal gastrointestinal tract were submitted for histopathologic analysis. Treatment with metronidazole or fenbendazole alone or in combination, failed to clear S. muris infected mice. After 4 wk of treatment, none of the mice given fenbendazole via sucralose medicated gel were positive by either PCR or histopathology; however, this finding is most likely due to intermittent shedding rather than chemotherapeutic success. Therefore, the recommendation remains to test-and-cull or rederive mice as necessary to eliminate S. muris from laboratory animal facilities.
