In this article, we elicit both individuals’ and couples’ preferences assuming prospect theory (PT) as a general theoretical framework for decision under risk. Our experimental method, based on certainty equivalents, allows to infer measurements of utility and probability weighting at the individual level and at the couple level. Our main results are twofold. First, risk attitude for couples is compatible with PT and incorporates deviations from expected utility similar to those found in individual decision making. Second, couples’ attitudes towards risk (...) are found to be consistent with a mix of individual attitudes, women being more influent on couples’ preferences at low probability levels. (shrink)

End-of-life organ donation is controversial in Islam. The controversy stems from: scientifically flawed medical criteria of death determination; invasive perimortem procedures for preserving transplantable organs; and incomplete disclosure of information to consenting donors and families. Data from a survey of Muslims residing in Western countries have shown that the interpretation of religious scriptures and advice of faith leaders were major barriers to willingness for organ donation. Transplant advocates have proposed corrective interventions: reinterpreting religious scriptures, reeducating faith leaders, and utilizing media (...) campaigns to overcome religious barriers in Muslim communities. This proposal disregards the intensifying scientific, legal, and ethical controversies in Western societies about the medical criteria of death determination in donors. It would also violate the dignity and inviolability of human life which are pertinent values incorporated in the Islamic moral code. Reinterpreting religious scriptures to serve the utilitarian objectives of a controversial end-of-life practice, perceived to be socially desirable, transgresses the Islamic moral code. It may also have deleterious practical consequences, as donors can suffer harm before death. The negative normative consequences of utilitarian secular moral reasoning reset the Islamic moral code upholding the sanctity and dignity of human life. (shrink)

The Royal College of Physicians of London published the 2013 national clinical guidelines on prolonged disorders of consciousness in vegetative and minimally conscious states. The guidelines acknowledge the rapidly advancing neuroscientific research and evolving therapeutic modalities in PDOC. However, the guidelines state that end-of-life decisions should be made for patients who do not improve with neurorehabilitation within a finite period, and they recommend withdrawal of clinically assisted nutrition and hydration . This withdrawal is deemed necessary because patients in PDOC can (...) survive for years with continuation of CANH, even when a ceiling on medical care has been imposed, i.e., withholding new treatment such as cardiopulmonary resuscitation for acute life-threatening illness. The end-of-life care pathway is centered on a staged escalation of medications, including sedatives, opioids, barbiturates, and general anesthesia, concurrent with withdrawal of CANH. Agitation and distress may last from several days to weeks because of the slow dying process from starvation and dehydration. The potential problems of this end-of-life care pathway are similar to those of the Liverpool Care Pathway. After an independent review in 2013, the Department of Health discontinued the Liverpool Care pathway in England. The guidelines assert that clinicians, supported by court decisions, have become the final authority in nonconsensual withdrawal of CANH on the basis of “best interests” rationale. We posit that these guidelines lack high-quality evidence supporting: 1) treatment futility of CANH, 2) reliability of distress assessment from starvation and dehydration, 3) efficacy of pharmacologic control of this distress, and 4) proximate causation of death. Finally, we express concerns about the utilitarian-based assessment of what constitutes a person’s best interests. We are disturbed by the level and the role of medical authoritarianism institutionalized by these national guidelines when deciding on the worthiness of life in PDOC. We conclude that these guidelines are not only harmful to patients and families, but they represent the means of nonconsensual euthanasia. The latter would constitute a gross violation of the public’s trust in the integrity of the medical profession. (shrink)

We respond to Morgan and Feeley’s critique on our article “Mass Media in Organ Donation: Managing Conflicting Messages and Interests.” We noted that Morgan and Feeley agree with the position that the primary aims of media campaigns are: “to educate the general public about organ donation process” and “help individuals make informed decisions” about organ donation. For those reasons, the educational messages in media campaigns should not be restricted to “information from pilot work or focus groups” but should include evidence-based (...) facts resulting from a comprehensive literature research. We consider the controversial aspects about organ donation to be relevant, if not necessary, educational materials that must be disclosed in media campaigns to comply with the legal and moral requirements of informed consent. With that perspective in mind, we address the validity of Morgan and Feeley’s claim that media campaigns have no need for informing the public about the controversial nature of death determination in organ donation. Scientific evidence has proven that the criteria for death determination are inconsistent with the Uniform Determination of Death Act and therefore potentially harmful to donors. The decision by campaign designers to use the statutory definition of death without disclosing the current controversies surrounding that definition does not contribute to improved informed decision making. We argue that if Morgan and Feeley accept the important role of media campaigns to enhance informed decision making, then critical controversies should be disclosed. In support of that premise, we will outline: (1) the wide-spread scientific challenges to brain death as a concept of death; (2) the influence of the donor registry and team-huddling on the medical care of potential donors; (3) the use of authorization rather than informed consent for donor registration; (4) the contemporary religious controversy; and (5) the effects of training desk clerks as organ requestors at the Department of Motor Vehicles offices. We conclude that organ donation is a medical procedure subject to all the ethical obligations that the medical profession must uphold including that of transparency and truthfulness. (shrink)

In assisted dying, the end-of-life trajectory is shortened to relieve unbearable suffering. Unbearable suffering is defined broadly enough to include cognitive (early dementia), psychosocial or existential distress. It can include old-age afflictions that are neither life-threatening nor fatal in the “vulnerable elderly”. The voluntary refusal of food and fluids (VRFF) combined with continuous deep sedation (CDS) for assisted dying is legal. Scientific understanding of awareness of internal and external nociceptive stimuli under CDS is rudimentary. CDS may blunt the wakefulness component (...) of human consciousness without eradicating internal affective awareness of thirst and hunger. Patients may suffer because of the slow dying process following dehydration and starvation. The difficulty to adequately control distress, without bringing the dying process to a rapid conclusion by lethal pharmacological interventions, can cause feelings of guilt among hospice and medical staff. Furthermore, the double-effect principle is not applicable in these situations because the primary objective of VRFF is to hasten death. Legal and societal debate should focus on sharpening the boundaries between assisted dying and palliative care. This separation is necessary to: 1) uphold trust in the patient-phyician relationship, and 2) preserve integrity and ethics of the medical profession. (shrink)

Background Bioethics and law distinguish between the practices of "physician-assisted death" and "allowing the patient to die." Discussion Advances in biotechnology have allowed medical devices to be used as destination therapy that are designed for the permanent support of cardiac function and/or respiration after irreversible loss of these spontaneous vital functions. For permanent support of cardiac function, single ventricle or biventricular mechanical assist devices and total artificial hearts are implanted in the body. Mechanical ventilators extrinsic to the body are used (...) for permanent support of respiration. Clinical studies have shown that destination therapy with ventricular assist devices improves patient survival compared to medical management, but at the cost of a substantial alteration in end-of-life trajectories. The moral and legal assessment of the appropriateness and permissibility of complying with a patient's request to electively discontinue destination therapy in a life-terminating act in non-futile situations has generated controversy. Some argue that complying with this request is ethically justified because patients have the right to request withdrawal of unwanted treatment and be allowed to die of preexisting disease. Other commentators reject the argument that acceding to an elective request for death by discontinuing destination therapy is 'allowing a patient to die' because of serious flaws in interpreting the intention, causation, and moral responsibility of the ensuing death. Summary Destination therapy with cardiac and/or ventilatory medical devices replaces native physiological functions and successfully treats a preexisting disease. We posit that discontinuing cardiac and/or ventilatory support at the request of a patient or surrogate can be viewed as allowing the patient to die if--and only if--concurrent lethal pathophysiological conditions are present that are unrelated to those functions already supported by medical devices in destination therapy. In all other cases, compliance with a patient's request constitutes physician-assisted death because of the pathophysiology induced by the turning off of these medical devices, as well as the intention, causation, and moral responsibility of the ensuing death. The distinction between allowing the patient to die and physician-assisted death is pivotal to the moral and legal status of elective requests for death by discontinuing destination cardiac and/or ventilatory medical devices in patients who are not imminently dying. This distinction also represents essential information that must be disclosed to patients and surrogates in advance of consent to this type of therapy. (shrink)

Mass media campaigns are widely and successfully used to change health decisions and behaviors for better or for worse in society. In the United States, media campaigns have been launched at local offices of the states’ department of motor vehicles to promote citizens’ willingness to organ donation and donor registration. We analyze interventional studies of multimedia communication campaigns to encourage organ-donor registration at local offices of states’ department of motor vehicles. The media campaigns include the use of multifaceted communication tools (...) and provide training to desk clerks in the use of scripted messages for the purpose of optimizing enrollment in organ-donor registries. Scripted messages are communicated to customers through mass audiovisual entertainment media, print materials and interpersonal interaction at the offices of departments of motor vehicles. These campaigns give rise to three serious concerns: (1) bias in communicating information with scripted messages without verification of the scientific accuracy of information, (2) the provision of misinformation to future donors that may result in them suffering unintended consequences from consenting to medical procedures before death (e.g, organ preservation and suitability for transplantation), and (3) the unmanaged conflict of interests for organizations charged with implementing these campaigns, (i.e, dual advocacy for transplant recipients and donors). We conclude the following: (1) media campaigns about healthcare should communicate accurate information to the general public and disclose factual materials with the least amount of bias; (2) conflicting interests in media campaigns should be managed with full public transparency; (3) media campaigns should disclose the practical implications of procurement as well as acknowledge the medical, legal, and religious controversies of determining death in organ donation; (4) organ-donor registration must satisfy the criteria of informed consent; (5) media campaigns should serve as a means of public education about organ donation and should not be a form of propaganda.

Past research has examined the ethical judgments of consumers in the U.S., but few studies have investigated such attitudes in foreign-market settings. The current study compares ethical attitudes of consumers in two countries (Ireland and Lebanon) which share a cultural similarity of ongoing war and terrorism. The findings reveal that both cultures exhibit low sensitivity to ethical issues. Furthermore, the findings show that the Irish consumers are less sensitive to consumer ethical practices, less idealistic, more relativistic, and more Machiavellian than (...) Lebanese consumers. The authors recommend that other researchers need to further investigate this perplexing issue because ethics is a research topic which often discourages survey respondents to be candid. (shrink)

The utilitarian construct of two alternative criteria of human death increases the supply of transplantable organs at the end of life. Neither the neurological criterion (heart-beating donation) nor the circulatory criterion (non-heart-beating donation) is grounded in scientific evidence but based on philosophical reasoning. A utilitarian death definition can have unintended consequences for dying Muslim patients: (1) the expedited process of determining death for retrieval of transplantable organs can lead to diagnostic errors, (2) the equivalence of brain death with human death (...) may be incorrect, and (3) end-of-life religious values and traditional rituals may be sacrificed. Therefore, it is imperative to reevaluate the two different types and criteria of death introduced by the Resolution (Fatwa) of the Council of Islamic Jurisprudence on Resuscitation Apparatus in 1986. Although we recognize that this Fatwa was based on best scientific evidence available at that time, more recent evidence shows that it rests on outdated knowledge and understanding of the phenomenon of human death. We recommend redefining death in Islam to reaffirm the singularity of this biological phenomenon as revealed in the Quran 14 centuries ago. (shrink)

Organ donation after cardiac or circulatory death (DCD) has been introduced to increase the supply of transplantable organs. In this paper, we argue that the recovery of viable organs useful for transplantation in DCD is not compatible with the dead donor rule and we explain the consequential ethical and legal ramifications. We also outline serious deficiencies in the current consent process for DCD with respect to disclosure of necessary elements for voluntary informed decision making and respect for the donor's autonomy. (...) We compare two alternative proposals for increasing organ donation consent in society: presumed consent and mandated choice. We conclude that proceeding with the recovery of transplantable organs from decedents requires a paradigm change in the ethics of organ donation. The paradigm change to ensure the legitimacy of DCD practice must include: (1) societal agreement on abandonment of the dead donor rule, (2) legislative revisions reflecting abandonment of the dead donor rule, and (3) requirement of mandated choice to facilitate individual participation in organ donation and to ensure that decisions to participate are made in compliance with the societal values of respect for autonomy and self-determination.

The mitochondrion is known as the “powerhouse” of eukaryotic cells since it is the main site of adenosine 5′‐triphosphate (ATP) production. Using a temperature‐sensitive fluorescent probe, it has recently been suggested that the stray free energy, not captured into ATP, is potentially sufficient to sustain mitochondrial temperatures higher than the cellular environment, possibly reaching up to 50 °C. By 50 °C, some DNA and mitochondrial proteins may reach their melting temperatures; how then do these biomolecules maintain their structure and function? (...) Further, the production of reactive oxygen species (ROS) accelerates with temperature, implying higher oxidative stresses in the mitochondrion than generally appreciated. Herein, it is proposed that mitochondrial heat shock proteins (particularly Hsp70), in addition to their roles in protein transport and folding, protect mitochondrial proteins and DNA from thermal and ROS damage. Other thermoprotectant mechanisms are also discussed. (shrink)

In early 2017, Nevada amended its Uniform Determination of Death Act, in order to clarify the neurologic criteria for the determination of death. The amendments stipulate that a determination of death is a clinical decision that does not require familial consent and that the appropriate standard for determining neurologic death is the American Academy of Neurology’s guidelines. Once a physician makes such a determination of death, the Nevada amendments require the withdrawal of life-sustaining treatment within twenty-four hours with limited exceptions. (...) Neurologists have generally supported Nevada’s amendments for clarifying the diagnostic standard and limiting the ability of family members to challenge it. However, it is more appropriate to view the Nevada amendments with concern. Even though the primary purpose of the UDDA is to ensure that all functions of a person’s entire brain have ceased, the AAN guidelines do not accurately assess this. In addition, by characterizing the determination of death as solely a clinical decision, the Nevada legislature has improperly ignored the doctrine of informed consent, as well as the beliefs of particular faiths and cultures that reject brain death. Rather than resolving controversies regarding brain death determinations, the Nevada amendments may instead instigate numerous constitutional challenges. (shrink)

In 1968, the Harvard criteria equated irreversible coma and apnea with human death and later, the Uniform Determination of Death Act was enacted permitting organ procurement from heart-beating donors. Since then, clinical studies have defined a spectrum of states of impaired consciousness in human beings: coma, akinetic mutism, minimally conscious state, vegetative state and brain death. In this article, we argue against the validity of the Harvard criteria for equating brain death with human death. Brain death does not disrupt somatic (...) integrative unity and coordinated biological functioning of a living organism. Neurological criteria of human death fail to determine the precise moment of an organism’s death when death is established by circulatory criterion in other states of impaired consciousness for organ procurement with non-heart-beating donation protocols. The criterion of circulatory arrest 75 s to 5 min is too short for irreversible cessation of whole brain functions and respiration controlled by the brain stem. Brain -based criteria for determining death with a beating heart exclude relevant anthropologic, psychosocial, cultural, and religious aspects of death and dying in society. Clinical guidelines for determining brain death are not consistently validated by the presence of irreversible brain stem ischemic injury or necrosis on autopsy; therefore, they do not completely exclude reversible loss of integrated neurological functions in donors. The questionable reliability and varying compliance with these guidelines among institutions amplify the risk of determining reversible states of impaired consciousness as irreversible brain death. The scientific uncertainty of defining and determining states of impaired consciousness including brain death have been neither disclosed to the general public nor broadly debated by the medical community or by legal and religious scholars. Heart-beating or non-heart-beating organ procurement from patients with impaired consciousness is de facto a concealed practice of physician-assisted death, and therefore, violates both criminal law and the central tenet of medicine not to do harm to patients. Society must decide if physician-assisted death is permissible and desirable to resolve the conflict about procuring organs from patients with impaired consciousness within the context of the perceived need to enhance the supply of transplantable organs.

Nursing Inquiry 2012; 19: 116–127 [Epub ahead of print]Finding middle ground: negotiating university and tribal community interests in community‐based participatory researchCommunity‐based participatory research (CBPR) has been hailed as an alternative approach to one‐sided research endeavors that have traditionally been conducted on communities as opposed to with them. Although CBPR engenders numerous relationship strengths, through its emphasis on co‐sharing, mutual benefit, and community capacity building, it is often challenging as well. (...) In this article, we describe some of the challenges of implementing CBPR in a research project designed to prevent cardiovascular disease among an indigenous community in the Pacific Northwest of the United States and how we addressed them. Specifically, we highlight the process of collaboratively constructing a Research Protocol/Data Sharing Agreement and qualitative interview guide that addressed the concerns of both university and tribal community constituents. Establishing these two items was a process of negotiation that required: (i) balancing of individual, occupational, research, and community interests; (ii) definition of terminology (e.g., ownership of data); and (iii) extensive consideration of how to best protect research participants. Finding middle ground in CBPR requires research partners to examine and articulate their own assumptions and expectations, and nurture a relationship based on compromise to effectively meet the needs of each group.

Advance health care directives and informed consent remain the cornerstones of patients' right to self-determination regarding medical care and preferences at the end-of-life. However, the effectiveness and clinical applicability of advance health care directives to decision-making on the use of life support systems at the end-of-life is questionable. The Uniform Anatomical Gift Act (UAGA) has been revised in 2006 to permit the use of life support systems at or near death for the purpose of maximizing procurement opportunities of organs medically (...) suitable for transplantation. Some states have enacted the Revised UAGA (2006) and a few of those have included amendments while attempting to preserve the uniformity of the revised Act. Other states have introduced the Revised UAGA (2006) for legislation and remaining states are likely to follow soon. (shrink)

There is a trend of recruiting faith leaders at mosques to overcome religious barriers to organ donation, and to increase donor registration among Muslims. Commentators have suggested that Muslims are not given enough information about organ donation in religious sermons or lectures delivered at mosques. Corrective actions have been recommended, such as funding campaigns to promote organ donation, and increasing the availability of organ donation information at mosques. These actions are recommended despite published literature expressing safety concerns (i.e., do no (...) harm) in living and end-of-life organ donation. Living donors require life-long medical follow-up and treatment for complications that can appear years later. Scientific and medical controversies persist regarding the international guidelines for death determination in end-of-life donation. The medical criteria of death lack validation and can harm donors if surgical procurement is performed without general anesthesia and before biological death. In the moral code of Islam, the prevention of harm holds precedence over beneficence. Moral precepts described in the Quran encourage Muslims to be beneficent, but also to seek knowledge prior to making practical decisions. However, the Quran also contains passages that demand honesty and truthfulness when providing information to those who are seeking knowledge. Currently, information is limited to that which encourages donor registration. Campaigning for organ donation to congregations in mosques should adhere to the moral code of complete, rather than selective, disclosure of information. We recommend as a minimal standard the disclosure of risks, uncertainties, and controversies associated with the organ donation process. (shrink)

Recently, several articles in the scholarly literature on medical ethics proclaim the need for “responsible scholarship” in the debate over the proper criteria for death, in which “responsible scholarship” is defined in terms of support for current neurological criteria for death. In a recent article, James M. DuBois is concerned that academic critiques of current death criteria create unnecessary doubt about the moral acceptability of organ donation, which may affect the public’s willingness to donate. Thus he calls for a closing (...) of the debate on current death criteria and for journal editors to publish only critiques that “substantially engage and advance the debate.” We argue that such positions as DuBois’ are a threat to responsible scholarship in medical ethics, especially scholarship that opposes popular stances, because it erodes academic freedom and the necessity of debate on an issue that is literally a matter of life and death, no matter what side a person defends.

Risk attitude is known to be a key determinant of various economic and financial choices. Behavioral studies that aim to evaluate the role of risk attitudes in contexts of this type, therefore, require tools for measuring individual risk tolerance. Recent developments in decision theory provide such tools. However, the methods available can be time consuming. As a result, some practitioners might have an incentive to prefer “fast and frugal” methods to clean but more costly methods. In this article, we focus (...) on a tractable procedure initially proposed by Holt and Laury (2002) to elicit risk attitude. We generalize this method to measure utility and risk aversion as follows. First, we allow measurement of probabilistic risk attitude through violations of expected utility due to probability weighting. Second, we use the outcome scale rather than the probability scale in the menu of choices. Third, we compare sure payoffs with lotteries instead of comparing non-degenerate lotteries. A within-subject experimental study illustrates the gains in tractability and bias minimization that can result from such an extension. (shrink)

This book brings together the ideas of a number of contemporary modernist and liberal Muslim thinkers, exposing an important intellectual current in Islamic thought which will be new to many Western readers. Responding to the challenges brought by colonialism and modernization, the contributors propose new conceptions and interpretations of Islam consonant with the age. Although their specific concerns and emphases vary, they all reconsider the relation between religion and politics and the incorporation of modern Western ideas.

Organ donation after cessation of circulation and respiration, both controlled and uncontrolled, has been proposed by the Institute of Medicine as a way to increase opportunities for organ procurement. Despite claims to the contrary, both forms of controlled and uncontrolled donation after cardiac death raise significant ethical and legal issues. Identified causes for concern include absence of agreement on criteria for the declaration of death, nonexistence of universal guidelines for duration before stopping resuscitation efforts and techniques, and assumption of presumed (...) intent to donate for the purpose of initiating temporary organ-preservation interventions when no expressed consent to donate is present. From a legal point of view, not having scientifically valid criteria of cessation of circulation and respiration for declaring death could lead to a conclusion that organ procurement itself is the proximate cause of death. Although the revised Uniform Anatomical Gift Act of 2006 provides broad immunity to those involved in organ-procurement activities, courts have yet to provide an opinion on whether persons can be held liable for injuries arising from the determination of death itself. Preserving organs in uncontrolled donation after cardiac death requires the administration of life-support systems such as extracorporeal membrane oxygenation. These life-support systems can lead to return of signs of life that, in turn, have to be deliberately suppressed by the administration of pharmacological agents. Finally, allowing temporary organ-preservation interventions without expressed consent is inherently a violation of the principle of respect for a person's autonomy. Proponents of organ donation from uncontrolled donation after cardiac death, on the other hand, claim that these nonconsensual interventions enhance respect for autonomy by allowing people, through surrogate decision making, to execute their right to donate organs. However, the lack of transparency and the absence of protection of individual autonomy, for the sake of maximizing procurement opportunities, have placed the current organ-donation system of opting-in in great jeopardy. Equally as important, current policies enabling and enhancing organ procurement practices, pose challenges to the constitutional rights of individuals in a pluralistic society as these policies are founded on flawed medical standards for declaring death.
