Occupational therapy often uses craft activities as therapeutic tools, but their therapeutic effectiveness has not yet been adequately demonstrated. The aim of this study was to examine changes in frontal midline theta rhythm and autonomic nervous responses during craft activities, and to explore the physiological mechanisms underlying the therapeutic effectiveness of occupational therapy. To achieve this, we employed a simple craft activity as a task to induce Fmθ and performed simultaneous EEG and ECG recordings. For participants in which Fmθ (...) activities were provoked, parasympathetic and sympathetic activities were evaluated during the appearance of Fmθ and rest periods using the Lorenz plot analysis. Both parasympathetic and sympathetic indices increased with the appearance of Fmθ compared to during resting periods. This suggests that a relaxed-concentration state is achieved by concentrating on craft activities. Furthermore, the appearance of Fmθ positively correlated with parasympathetic activity, and theta band activity in the frontal area were associated with sympathetic activity. This suggests that there is a close relationship between cardiac autonomic function and Fmθ activity. (shrink)

Interoception in the broader sense refers to the perception of internal states, including the perception of the actual state of the internal organs and the motor system. Dimensions of interoception include interoceptive accuracy, i.e., the ability to sense internal changes assessed with behavioral tests, confidence rating with respect to perceived performance in an actual behavioral test, and interoceptive sensibility, i.e., the self-reported generalized ability to perceive body changes. The relationship between dimension of cardioceptive and proprioceptive modalities and their (...) association with affect are scarcely studied. In the present study, undergraduate students filled out questionnaires assessing positive and negative affect, interoceptive sensibility, and body competence. Following this, they completed a behavioral task assessing cardioceptive accuracy and two tasks assessing proprioceptive accuracy with respect to the tension of arm flexor muscles and the angular position of the elbow joint. Confidence ratings were measured with visual analog scales after the tasks. With the exception of a weak association between cardioceptive accuracy and the respective confidence rating, no associations between and within modalities were found with respect to various dimensions of interoception. Further, the interoceptive dimensions were not associated with state and trait positive and negative affect and perceived body competence. In summary, interoceptive accuracy scores do not substantially contribute to conscious representations of cardioceptive and proprioceptive ability. Within our data, non-pathological affective states are not associated with the major dimensions of interoception for the cardiac and proprioceptive modalities. (shrink)

This paper examines the ethical aspects of organ transplant surgery in which a donor heart is transplanted from a first recipient, following determination of death by neurologic criteria, to a second recipient. Retransplantation in this sense differs from that in which one recipient undergoes repeat heart transplantation of a newly donated organ, and is thus referred to here as “reuse cardiac organ transplantation.” Medical, legal, and ethical analysis, with a main focus on ethical analysis. From the medical perspective, it (...) is critical to ensure the quality and safety of reused organs, but we lack sufficient empirical data pertaining to medical risk. From the legal perspective, a comparative examination of laws in the United States and Japan affirms no illegality, but legal scholars disagree on the appropriate analysis of the issues, including whether or not property rights apply to transplanted organs. Ethical arguments supporting the reuse of organs include the analogous nature of donation to gifts, the value of donations as inheritance property, and the public property theory as it pertains to organs. Meanwhile, ethical arguments such as those that address organ recycling and identity issues challenge organ reuse. We conclude that organ reuse is not only ethically permissible, but even ethically desirable. Furthermore, we suggest changes to be implemented in the informed consent process prior to organ transplantation. The organ transplant community worldwide should engage in wider and deeper discussions, in hopes that such efforts will lead to the timely preparation of guidelines to implement reuse cardiac organ transplantation as well as reuse transplantation of other organs such as kidney and liver.

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.

In this article, I argue that there is a moral difference between deactivating an implantable cardioverter defibrillator and turning off a cardiac pacemaker. It is, at least in most cases, morally permissible to deactivate an ICD. It is not, at least in most cases, morally permissible to turn off a pacemaker in a fully or significantly pacemaker-dependent patient. After describing the relevant medical technologies—pacemakers and ICDs—I continue with contrasting perspectives on the issue of deactivation from practitioners involved with these (...) devices: physicians, nurses, and allied professionals. Next, I offer a few possible analyses of the situation, relying on recent work in medical ethics. Considerations of intention, responsibility, and replacement support my distinguishing between ICDs and CPs. I conclude by recommending a change in policy of one of the leading cardiac societies.

A number of studies show that when doctors become ill, there is often ambiguity in the division of roles and responsibilities in the medical encounter. Yet little is known about how the dilemma of the sick doctor has changed over time. This article explores the experience of illness among physicians by applying an historical, narratological approach to three doctor’s narratives about personal cases of cardiac disease: Max Pinner’s from the 1940s, Robert Seaver’s from the 1980s, and John Mulligan’s from (...) 2015. Drawing on Erving Goffman’s principles of social interaction, I argue that part of the challenge in the analysed narratives is because when doctors seek medical attention for themselves, the ensuing medical ‘drama’ suffers. I compare the three narratives to argue that the experience of becoming a patient while simultaneously remaining a doctor is a challenge that has changed over time. In Pinner’s narrative, the patient identity is both undesirable and inaccessible; in Seaver’s, role ambivalence between doctor and patient is the most salient feature; for Mulligan, his personal rather than professional experience of illness is the overarching theme of the narrative. Finally, I suggest that an awareness of how the medical drama often changes when doctors are patients might prove beneficial both for the doctor-patients and providers of medical care. (shrink)

In this article a concept of non-local consciousness will be described, based on recent scientific research on near-death experiences . Since the publication of several prospective studies on NDEs in survivors of cardiac arrest, with strikingly similar results and conclusions, the phenomenon of the NDE can no longer be scientifically ignored. In the last thirty years several theories have been proposed to explain an NDE. The challenge to find a common explanation for the cause and content of an NDE (...) is complicated by the fact that an NDE can be experienced during various circumstances, such as severe injury of the brain as in cardiac arrest to conditions when the brain seems to function normally. The NDE is an authentic experience which cannot be simply reduced to imagination, fear of death, hallucination, psychosis, the use of drugs, or oxygen deficiency. Patients appear to be permanently changed by an NDE during a cardiac arrest of only some minutes duration. According to these aforementioned studies, the current materialistic view of the relationship between consciousness and the brain as held by most physicians, philosophers, and psychologists is too restricted for a proper understanding of this phenomenon. There are good reasons to assume that our consciousness does not always coincide with the functioning of our brain: enhanced or non-local consciousness can sometimes be experienced separately from the body.

“I think there’s a big strong belief in [...] the community … and maybe it’s in the world at large that somehow the doctors are more concerned about harvesting the organs than what’s best for the patient.”1 In the past 45 years, organ and tissue recovery and transplantation have moved from the occasional and experimental to a standard of care for end-stage organ failure; receiving an organ transplant is for many the only opportunity for increased quantity and/or quality of life. (...) The increasing prevalence of diseases such as viral hepatitis, diabetes, and hypertension has significantly increased the incidence of end-organ failure. Additionally, surgical advances have permitted less stringent qualification criteria, so that people of advanced age or patients who may be in a physiologically fragile state are now eligible to be organ recipients. These changes have created a significant demand for organs. (shrink)

The ethics of hastened death are complex. Studies on physicians’ opinions about assisted dying exist, but changes in physicians’ attitudes towards hastened death in clinical decision-making and the background factors explaining this remain unclear. The aim of this study was to explore the changes in these attitudes among Finnish physicians. A questionnaire including hypothetical patient scenarios was sent to 1182 and 1258 Finnish physicians in 1999 and 2015, respectively. Two scenarios of patients with advanced cancer were presented: one (...) requesting an increase in his morphine dose to a potentially lethal level and another suffering a cardiac arrest. Physicians’ attitudes towards assisted death, life values and other background factors were queried as well. The response rate was 56%. The morphine dose was increased by 25% and 34% of the physicians in 1999 and 2015, respectively. Oncologists approved the increase most infrequently without a significant change between the study years. Oncological specialty, faith in God, female gender and younger age were independent factors associated with the reluctance to increase the morphine dose. Euthanasia, but not assisted suicide, was considered less reprehensible in 2015. In both years, most physicians withheld cardiopulmonary resuscitation. Finnish physicians accepted the risk of hastening death more often in 2015 than in 1999. The physicians’ specialty and many other background factors influenced this acceptance. They also regarded euthanasia as less reprehensible now than they did 16 years ago. (shrink)

BackgroundConsent for data research in acute and critical care is complex as patients become at least temporarily incapacitated or die. Existing guidelines and regulations in the European Union are of limited help and there is a lack of literature about the use of data from this vulnerable group. To aid the creation of a patient-centred framework for responsible data research in the acute setting, we explored views of patients and next-of-kin about the collection, storage, sharing and use of genetic and (...) health-related data for observational research.MethodsWe conducted qualitative interviews (n = 19) with Dutch sudden cardiac arrest survivors who donated clinical and socio-economic data and genetic samples to research. We also interviewed their next-of-kin. Topics were informed by ethics literature and we used scenario-sketches to aid discussion of complex issues.ResultsSudden cardiac arrest survivors displayed limited awareness of their involvement in health data research and of the content of their given consent. We found that preferences regarding disclosure of clinically actionable genetic findings could change over time. When data collection and use were limited to the medical realm, patients trusted researchers to handle data responsibly without concern for privacy or other risks. There was no consensus as to whether deferred consent should be explicitly asked from survivors. If consent is asked, this would ideally be done a few months after the event when cognitive capacities have been regained. Views were divided about the need to obtain proxy consent for research with deceased patients’ data. However, there was general support for the disclosure of potentially relevant post-mortem genetic findings to relatives.ConclusionsSudden cardiac arrest patients’ donation of data for research was grounded in trust in medicine overall, blurring the boundary between research and care. Our findings also highlight questions about the acceptability of a one-time consent and about responsibilities of patients, researchers and ethics committees. Finally, further normative investigation is needed regarding the (continued) use of participants’ data after death, which is of particular importance in this setting. Our findings are thought to be of relevance for other acute and life-threatening illnesses as well. (shrink)

The aim of this paper is to investigate whether or not ethical conflicts can be identified, analysed and solved using ethical principles. The relation between the physician and the patient with ischemic heart disease (IHD) as life style changes are recommended in a secondary prevention program is used as an example. The principal persons affected (the patient and his or her spouse) and the ethical principles (respect for autonomy, non-maleficence, beneficence and justice) are combined in a two dimensional model. (...) The most important person affected by the recommendations is the patient. His or her autonomy is challenged by the suggested life style changes, the purpose of which is to promote the future wellbeing and health of the patient. The spouse is indirectly involved in and affected by the process. He or she often feels neglected by caregivers. Ethical conflicts can both be identified and analysed using ethical principles, but often no solution is implied. Most (if not all) physicians would strongly encourage life style changes, but surprisingly there is no uncontroversial justification for this conclusion using principles. (shrink)

Background: Ethical frameworks for organ donation following circulatory death (DCD) were established >20 years ago. However, considerable variation exists among these, indicating consensus has not been reached on all issues. Additionally, advances such as cardiac DCD transplants and normothermic regional perfusion (NRP) may have reignited old debates.Methods: We reviewed the English-language literature addressing ethical issues in DCD from 1993 to 2022, examining changes in frequency with which ethical principles and their sub-themes identified within each, were addressed.Results: Non-maleficence was (...) the most frequently addressed principle (192 of 199 articles), as well as the most varied, with 9 subthemes (versus 2-4 within each of the other bioethical principles).Conclusions: There were several changes in the terminology used to refer to DCD over time, and substantial interest in cardiac DCD and NRP in recent publications, arising in 11 and 19 of the 30 publications from 2018 to 2022.

: Research by Siminoff and colleagues reveals that many lay people in Ohio classify legally living persons in irreversible coma or persistent vegetative state (PVS) as dead and that additional respondents, although classifying such patients as living, would be willing to procure organs from them. This paper analyzes possible implications of these findings for public policy. A majority would procure organs from those in irreversible coma or in PVS. Two strategies for legitimizing such procurement are suggested. One strategy would be (...) to make exceptions to the dead donor rule permitting procurement from those in PVS or at least those who are in irreversible coma while continuing to classify them as living. Another strategy would be to further amend the definition of death to classify one or both groups as deceased, thus permitting procurement without violation of the dead donor rule. Permitting exceptions to the dead donor rule would require substantial changes in law—such as authorizing procuring surgeons to end the lives of patients by means of organ procurement—and would weaken societal prohibitions on killing. The paper suggests that it would be easier and less controversial to further amend the definition of death to classify those in irreversible coma and PVS as dead. Incorporation of a conscience clause to permit those whose religious or philosophical convictions support whole-brain or cardiac-based death pronouncement would avoid violating their beliefs while causing no more than minimal social problems. The paper questions whether those who would support an exception to the dead donor rule in these cases and those would support a further amendment to the definition of death could reach agreement to adopt a public policy permitting organ procurement of those in irreversible coma or PVS when proper consent is obtained.

The developing mammalian heart responds to a variety of conditions, including changes in nutrient availability, blood oxygenation, hemodynamics, or tissue homeostasis, with impressive growth plasticity. This ensures the formation of a functional and normal sized organ by birth. During embryonic and fetal development the heart is exposed to various physiological and potentially pathological changes in the intrauterine environment which dramatically impact on normal cardiac function, tissue composition, and morphology. This paper summarizes the mechanisms employed by the embryonic (...) and fetal heart to adapt to various intrauterine challenges to prevent or minimize postnatal consequences of impaired cardiac development. Future investigations of this growth plasticity might lead to new therapeutic strategies for the prevention of cardiac disease in postnatal life. (shrink)

Extracorporeal membrane oxygenation (ECMO) is a form of life support for cardiac and/or pulmonary failure with unique ethical challenges compared to other forms of life support. Ethical challenges with ECMO exist when conventional standards of care apply, and are exacerbated during periods of absolute ECMO scarcity when “crisis standards of care” are instituted. When conventional standards of care apply, we propose that it is ethically permissible to withhold placing patients on ECMO for reasons of technical futility or when patients (...) have terminal, short-term prognoses that are untreatable by ECMO. Under crisis standards of care, it is ethically permissible to broaden exclusionary criteria to also withhold ECMO from patients who have a low likelihood of recovery, to maximize the overall number of lives saved. Unilateral withdrawal of ECMO against a patient’s preferences is unethical under conventional standards of care, but is ethical under crisis standards of care to increase access to ECMO to others in society. ECMO should only be rationed when true scarcity exists, and allocation protocols should be transparent to the public. When rationing must occur under crisis standards of care, it is imperative that oversight bodies assess for inequities in the allocation of ECMO and make frequent changes to improve any inequities.

Heart rate variability (HRV), the change in the time intervals between adjacent heartbeats, is an emergent property of interdependent regulatory systems that operate on different time scales to adapt to challenges and achieve optimal performance. This article briefly reviews neural regulation of the heart, and its basic anatomy, the cardiac cycle, and the sinoatrial and atrioventricular pacemakers. The cardiovascular regulation center in the medulla integrates sensory information and input from higher brain centers, and afferent cardiovascular system inputs to adjust (...) heart rate and blood pressure via sympathetic and parasympathetic efferent pathways. This article reviews sympathetic and parasympathetic influences on the heart, and examines the interpretation of HRV and the association between reduced HRV, risk of disease and mortality, and the loss of regulatory capacity. This article also discusses the intrinsic cardiac nervous system and the heart-brain connection, through which afferent information can influence activity in the subcortical and frontocortical areas, and motor cortex. It also considers new perspectives on the putative underlying physiological mechanisms and properties of the ultra-low-frequency (ULF), very-low-frequency (VLF), low-frequency (LF), and high-frequency (HF) bands. Additionally, it reviews the most common time and frequency domain measurements as well as standardized data collection protocols. In its final section, this article integrates Porges' polyvagal theory, Thayer and colleagues' neurovisceral integration model, Lehrer et al.'s resonance frequency model, and the Institute of HeartMath's coherence model. The authors conclude that a coherent heart is not a metronome because its rhythms are characterized by both complexity and stability over longer time scales. Future research should expand understanding of how the heart and its intrinsic nervous system influence the brain. (shrink)

Background: Monitoring the daily change in resting heart rate variability can provide information regarding training adaptation and recovery status of the autonomic nervous system during training camps. However, it remains unclear whether postural stabilization is essential for valid and reliable ultra-short-term recordings in short-term overseas training camps.Design: Observational and longitudinal study.Purpose: This study aimed to investigate ultra-short-term heart rate variability recordings under stabilization or post-stabilization periods in four overseas training camps.Participant: Twenty-seven U-20 male national team futsal players voluntarily participated in (...) this study.Method: Resting HRV was evaluated for 10 min during the early morning of each training camp. The natural logarithm of the root mean square of successive normal-to-normal interval differences was used for comparisons. Time segments of HRV were divided into two periods with three measures within each: the first 30-s, the first 60-s, and the 5-min standard during stabilization; the first 30-s, the first 60-s, and the 5-min standard after stabilization.Result: The results demonstrated trivial to small ES, very large to nearly perfect ICC, and narrow range of SEM when all time segments of HRVUST were compared to the 1st_5 min and 2nd_5 min HRV. Furthermore, the magnitude of the correlation coefficients ranged from very high to nearly perfect for all the time segments. The HRVUST posted excellent agreement in all time segments with/without postural stabilization. Trivial to small levels of effect size in all time segments of LnRMSSDmean and LnRMSSDcv across overseas training camps was identified.Conclusion: The first 30 or 60-s LnRMSSD recordings can be used to evaluate daily cardiac-autonomic function during overseas training camps in futsal players. The process for stabilization seems to be unnecessary for measuring the morning resting LnRMSSD in overseas training camps among young adult futsal players. (shrink)

This article discusses the response of our ethics consultation service to an exceptional request by a patient to have his implantable cardioverter defibrillator removed. Despite assurances that the device had saved his life on at least two occasions, and cautions that without it he would almost certainly suffer a potentially lethal cardiac event within 2 years, the patient would not be swayed. Although the patient was judged to be competent, our protracted consultation process lasted more than 8 months as (...) we consulted, argued with, and otherwise cajoled him to change his mind, all to no avail. Justifying our at times aggressive paternalistic intervention helped us to reflect on the nature of autonomy and the dynamics of the legal, moral, and personal relationships in the clinical decision-making process.

Dynamic intra-individual variability (IIV) in cardiac vagal control across multiple situations is believed to contribute to adaptive cognition under stress; however, a dearth of research has empirically tested this notion. To this end, we examined 25 U.S. Army Soldiers (all male, Mean Age= 30.73, SD = 7.71) whose high-frequency heart rate variability (HF-HRV) was measured during a resting baseline and during three conditions of a shooting task (training, low stress, high stress). Response inhibition was measured as the correct rejection (...) of friendly targets during the low and high stress conditions. We tested the association between the standard deviation of HF-HRV across all four task conditions (IIV in vagal control) and changes in response inhibition between low and high stress. Greater differences in vagal control between conditions (larger IIV) were associated with higher tonic vagal control during rest, and stronger stress-related decreases in response inhibition. These results suggest that flexibility in vagal control is supported by tonic vagal control, but this flexibility also uniquely relates to adaptive cognition under stress. Findings are consistent with neurobehavioral and dynamical systems theories of vagal function. (shrink)

PHOTO ID 121339257© Designer491| Dreamstime.com ABSTRACT When physicians use their clinical knowledge and skills to advance the well-being of their patients, there may be apparent conflict between patient autonomy and physician beneficence. We are skeptical that today’s medical ethics education adequately fosters future physicians’ commitment to beneficence, which is both rationally defensible and fundamentally consistent with patient autonomy. We use an ethical dilemma that was presented to a group of third-year medical students to examine how ethics education might be causing (...) them to give undue deference to autonomy, thereby undermining their commitment to beneficence. INTRODUCTION The right of patients to choose which treatments they prefer is rooted in today’s social mores and taught as a principle of medical ethics as respect for autonomy. Yet, when physicians use their clinical knowledge and skills to advance the well-being of their patients, there may be a conflict between patient autonomy and physician beneficence. We are skeptical that today’s medical ethics education adequately fosters a commitment to beneficence, which is both rationally defensible and fundamentally consistent with patient autonomy. I. An Ethical Dilemma The impetus for this paper arose when students who were completing their third clinical year discussed a real-life ethical dilemma. A middle-aged man developed a pulmonary hemorrhage while on blood thinners for a recently placed coronary stent. The bleeding was felt to be reversible, but the patient needed immediate intubation or he would die. The cardiologist was told that the patient previously expressed to other physicians that he never wanted to be intubated. However, the cardiologist made the decision to intubate the patient anyway, and the patient eventually recovered.[1] Students were asked if they believed that the cardiologist had acted ethically. Their overwhelming response was, “No, the patient should have been allowed to die.” We looked into how students applied ethical reasoning to conclude that this outcome was ethically preferred. To explore how the third-year clinical experience might have formed the students’ judgment, we presented the same case to students who were just beginning their third year. Their responses were essentially uniform in recommending intubation. While there is likely more than one reasonable view in this case, we agree with the physician and the younger medical students that intubation was the ethically appropriate decision and will present an argument for it. But first, we explain the reasoning behind the more advanced medical students’ decision to choose patient autonomy at the expense of beneficence. II. Medical Ethics Education and the Priority of Autonomy Beauchamp and Childress’s Principles of Biomedical Ethics, first published in 1979 and now in its 8th edition, is a significant part of the formal ethics education in medical school.[2] Students learn an ethical decision-making approach based on respect for four ethical principles: autonomy, beneficence, nonmaleficence, and justice. While Beauchamp and Childress officially afford no prima facie superiority to any principle, the importance of respect for patient autonomy has increased through the editions of their book. For example, early editions of their book opposed the legalization of physician-assisted death compared to recent editions that defended it.[3] As another example, Beauchamp and Childress make paternalism harder to justify by adding an autonomy-protecting condition to the list of conditions for acceptable paternalism.[4] Authority, they contend, need not conflict with autonomy—provided the authority is autonomously chosen.[5] “The main requirement,” they write, “is to respect a particular patient’s or subject’s autonomous choices, whatever they may be.[6] In the principlism of Beauchamp and Childress, autonomy now seems to have a kind of default priority.[7] However, the bioethics discourse has strong counternarratives, noting some movement to elevate the role of beneficence and to respect the input of stakeholders, including the family and the healthcare team. Ethics education achieves particular relevance in the third clinical year when students become embedded in the care of patients and learn from what has been called the informal curriculum. They observe how attending physicians approach day-to-day ethical problems at the patient’s bedside. In this context, students observe the importance of informed consent for serious treatments or invasive procedures, a practice that highlights the principle of patient autonomy. In both the formal and informal curriculum, medical students observe how, in the words of Paul Wolpe, “patient autonomy has become the central and most powerful principle in ethical decision-making in American medicine.”[8] In short, students appear to learn a deference for patient autonomy. This curricular shift in favor of autonomy coincides with legal developments that protect patients’ rights and decision-making with respect to their healthcare choices. The priority of autonomy in medicine benefits patients by reflecting their choices and, in some cases, their fundamental liberty. III. The Practice of Medicine and the Commitment to Beneficence There are many critiques of the dominant place that autonomy has in biomedical ethics,[9] especially considering that autonomy seems to be biased toward individualistic, Western, and somewhat American culture-driven values.[10] In addition, many bioethical dilemmas are cast as a conflict between autonomy and beneficence. Our point is that medical students bring to their study of medicine a commitment to beneficence that seems to be suppressed by practical ethics education. We think this commitment is rationally defensible and should be nurtured. It is striking that young medical students have a pre-reflective commitment to beneficence at all. For, as we mentioned, it is not just medicine but Western culture generally that prioritizes autonomy in settling ethical dilemmas. In wanting to act for the good of others (rather than simply agreeing to what others want), physicians are already swimming somewhat against the cultural tide.[11] However, doing so makes sense, given the nature of medicine and the profession of healing. When prospective medical students are asked why they wish to become physicians, the usual answer is some variation on caring for the sick and preventing disease. It is unlikely that a reason to become a physician is to respect a patient’s autonomy. It would be easy to dismiss medical students’ commitment to beneficence as a mere intuition and contrary to a more reasoned and deliberative approach. Beauchamp and Childress seem to minimize the value of physician intuition, stating that justifications for certain procedures are “…supported by good reasons. They need not rest merely in intuition or feeling.”[12] Henry Richardson writes that “situational or perceptive intuition…leaves the reasons for decision unarticulated.”[13] We think this is a crude and rather thin way of understanding intuition. Some bioethicists have defended intuition as essential to the practice of medicine and not something opposed to reason.[14] In the case we describe, we believe the ethical justifications s for the patient’s intubation are fundamentally sound: the patient did not have a “do not intubate” order written in the chart, the emergency intubation had not been foreseen, so the patient did not have the opportunity to consent to or reject intubation; the patient had consented to the treatment for his cardiac disease so his consent for intubation could have been assumed;[15] and the consequences of respecting his autonomy did not justify allowing him to die.[16] While it is possible to have more than one reasonable view on this case, we think the case for beneficence is strong and certainly should not be dismissed out of hand. We do not deny that if a patient makes a clearly documented, well-informed decision to forgo intubation that this decision ought to be respected by the physician (even if the physician disagrees with the patient’s decision). But, in this situation, as in many others in the practice of medicine, the patient’s real wishes and preferences are not well-articulated in advance. There are many cases where a physician acts based on what she believes the patient, or the surrogate, would want, sometimes in situations that do not allow much time for reflection. An example might be resuscitation of a newborn at the borderline of viability. In their ethics education, beneficence would mean acting first to save a life. If the patient or surrogate makes an informed decision to the contrary, a beneficent physician respects that autonomous decision. In the case presented, the patient expressed gratitude to the cardiologist when extubated. But what if he had expressed anger at the physician for violating his autonomy? There are those who could argue that not only was intubation ethically wrong but that the cardiologist put himself in legal jeopardy by his actions (especially if there had been a written refusal applicable to the specific situation). In the example we use, we point out that the cardiologist may not have escaped a lawsuit if the patient had died without intubation. His family, when hearing the circumstances, may have sued for failure to act and dereliction of the cardiologist’s duty to save him. Beyond a potential legal challenge for either action or inaction, there is an overriding ethical question the cardiologist had to address: what course would be most satisfying to his conscience? Would he rather allow a patient to die for fear of recrimination, or act to save his life, regardless of the personal consequences? In the absence of real knowledge about the patient’s considered wishes, it is most reasonable to err on the side of promoting patient well-being. A physician’s commitment to beneficence is not necessarily a way of undermining a patient’s autonomy. In acting for the patient's good, physicians are also acting on what it is reasonable to believe a patient (or most patients, perhaps) would want, which is obviously connected to what a patient does want. Pellegrino and Thomasma argue that beneficence includes respect for a patient’s autonomy since “the best interests of the patient are intimately linked with their preferences.”[17] Instead of conceptualizing ethical dilemmas in medicine as conflicts between autonomy and beneficence, it is possible that medical schools could teach students that truly practicing beneficence is a way of valuing patient autonomy, especially when the patient’s wishes are not specific to the situation and are not clearly expressed. CONCLUSION It is important for students and practicing physicians to understand the principle of respect for patient autonomy in a pluralistic society that demands personal self-determination. However, the role of the physician as a beneficent healer should not be diminished by this respect for autonomy. Respecting a patient’s autonomy is grounded in and manifested by physician beneficence.[18] That is, seeking what is good for the patient can only be good if it respects their personhood and dignity. We propose that a commitment to beneficence, incipient in young medical students, should be developed over time with their other clinical reasoning skills. Such a commitment need not be sacrificed on the altar of patient autonomy. Beneficence needs greater relative moral weight with students as they proceed in their ethics education. - [1] S.

Due to domestication, dogs differ from wolves in the way they respond to their environment, including to humans. Selection for tameness and the associated changes to the autonomic nervous system (ANS) regulation have been proposed as the primary mechanisms of domestication. To test this idea, we compared two low-arousal states in equally raised and kept wolves and dogs: resting, a state close to being asleep, and inactive wakefulness, which together take up an important part in the time budgets of (...) wolves and dogs. We measured arousal via cardiac output in three conditions: alone, with a familiar human partner, or with pack members (i.e., conspecifics). Specifically, we compared heart rate (HR) and heart rate variability (HRV) of six wolves and seven dogs. As patterns of resting can vary adaptively, even between closely related species, we predicted that dogs would be generally more aroused than wolves, because living with humans may come with less predictable contexts than living with conspecifics; hence, dogs would need to be responsive at all times. Furthermore, we predicted that due to the effects of domestication, emotional social support by familiar people would reduce arousal more in dogs than in equally human-socialized wolves, leading to more relaxed dogs than wolves when away from the pack. Overall, we found a clear effect of the interactions between species (i.e., wolf versus dog), arousal state (i.e., resting or awake inactive) and test conditions, on both HR and HRV. Wolves and dogs were more aroused when alone (i.e., higher HR and lower HRV) than when in the presence of conspecifics or a familiar human partner. Dogs were more relaxed than wolves when at rest and close to a familiar human but this difference disappeared when awake. In conclusion, instead of the expected distinct overall differences between wolves and dogs in ANS regulation, we rather found subtle context-specific responses, suggesting that such details are important in understanding the domestication process.

This discussion paper considers how seldom recognised theories influence clinical ethics committees. A companion paper examined four major theories in social science: positivism, interpretivism, critical theory and functionalism, which can encourage legalistic ethics theories or practical living bioethics, which aims for theory–practice congruence. This paper develops the legalistic or living bioethics themes by relating the four theories to clinical ethics committee members’ reported aims and practices and approaches towards efficiency, power, intimidation, justice, equality and children’s interests and rights. Different approaches (...) to framing ethical questions are also considered. Being aware of the four theories’ influence can help when seeking to understand and possibly change clinical ethics committee routines. The paper is not a research report but is informed by a recent study in two London paediatric cardiac units. Forty-five practitioners and related experts were interviewed, including eight members of ethics committees, about the work of informing, preparing and supporting families during the extended process of consent to children’s elective heart surgery. The mosaic of multidisciplinary teamwork is reported in a series of papers about each profession, including this one on bioethics and law and clinical ethics committees’ influence on clinical practice. The qualitative social research was funded by the British Heart Foundation, in order that more may be known about the perioperative views and needs of all concerned. Questions included how disputes can be avoided, how high ethical standards and respectful cooperation between staff and families can be encouraged, and how minors’ consent or refusal may be respected, with the support of clinical ethics committees.

This issue’s “Legal Briefing” column covers legal developments pertaining to organ donation and allocation. This topic has been the subject of recent articles in JCE. Organ donation and allocation have also recently been the subjects of significant public policy attention. In the past several months, legislatures and regulatory agencies across the United States and across the world have changed, or considered changing, the methods for procuring and distributing human organs for transplantation.Currently, in the U.S., more than 100,000 persons are waiting (...) for organ transplantation. In China, more than 1.5 million people are waiting. Given the chronic shortage of available organs (especially kidneys and livers) relative to demand, the primary focus of most legal developments has been on increasing the rate of donation. These and related developments are usefully divided into the following 12 topical categories: 1. Revised Uniform Anatomical Gift Act2. Presumed Consent and Opt-Out3. Mandated Choice4. Donation after Cardiac Death5. Payment and Compensation6. Donation by Prisoners7. Donor Registries8. Public Education9. Other Procurement Initiatives10. Lawsuits and Liability11.

Technology is pervasive and overwhelming in the intensive care setting. It has the power to inform and direct the nursing care of critically ill patients. Technology changes the moral and social dynamics within nurse—patient encounters. Nurses use technology as the main reference point to interpret and evaluate clinical patient outcomes. This shapes nurses’ understanding and the kind of care provided. Technology inserts itself between patients and nurses, thus distancing nurses from patients. This situates nurses into positions of power, granting (...) them epistemic authority, which constrains them as moral agents. Technology serves to categorize and marginalize patients’ illness experience. In this article, moral agency is examined within the technologically-mediated context of the intensive care unit. Uncritical use of technology has a negative impact on patient care and nurses’ view of patients, thus limiting moral agency. Through examination of technology as it frames cardiac patients, it is demonstrated how technology changes the way nurses understand and conceptualize moral agency. This article offers a new perspective on the ethical discussion of technology and its impact on nurses’ moral agency. Employing reflective analysis using the technique of embodied reflection may help to ensure that patients remain at the centre of nurses’ moral practice. Embodied reflection invites nurses critically to examine how technology has reshaped conceptualization, understanding, and the underlying motivation governing nurses’ moral agency. (shrink)

Background:Maintaining patient’s dignity in intensive care units is difficult because of the unique conditions of both critically-ill patients and intensive care units.Objectives:The aim of this study was to uncover the cultural factors that impeded maintaining patients’ dignity in the cardiac surgery intensive care unit.Research Design:The study was conducted using a critical ethnographic method proposed by Carspecken.Participants and research context:Participants included all physicians, nurses and staffs working in the study setting. Data collection methods included participant observations, formal and informal interviews, (...) and documents assessment. In total, 200 hours of observation and 30 interviews were performed. Data were analyzed to uncover tacit cultural knowledge and to help healthcare providers to reconstruct the culture of their workplace.Ethical Consideration:Ethical approval for the study from Ethics committee of Isfahan University of Medical Sciences was obtained.Findings:The findings of the study fell into the following main themes: “Presence: the guarantee for giving enough attention to patients’ self-esteem”, “Instrumental and objectified attitudes”, “Adherence to the human equality principle: value-action gap”, “Paternalistic conduct”, “Improper language”, and “Non-interactive communication”. The final assertion was “Reductionism as a major barrier to the maintaining of patient’s dignity”.Discussion:The prevailing atmosphere in subculture of the CSICU was reductionism and paternalism. This key finding is part of the biomedical discourse. As a matter of fact, it is in contrast with dignified care because the latter necessitate holistic attitudes and approaches.Conclusion:Changing an ICU culture is not easy; but through increasing awareness and critical self-reflections, the nurses, physicians and other healthcare providers, may be able to reaffirm dignified care and cure in their therapeutic relationships.

The transplant community has quietly initiated efforts to expand the current pool of cadaver organ donors to include those who are dead by cardiac criteria but cannot be pronounced dead using brain-based criteria. There are many reasons for concern about "policy creep" regarding who is defined as a potential organ donor. These reasons include loss of trust in the transplant community because of confusion over the protocols to be used, blurring the line between life and death, stress on family (...) members, and burdens imposed on health care providers when a long-standing policy regarding who can serve as a cadaver organ donor is unilaterally changed. While these concerns are not sufficient reason for abandoning efforts to broaden existing eligibility standards for cadaver donation, they are sufficient reasons for the transplant community to desist in changing existing standards without widespread professional and public discussion.

This study is a continuation of the work of Professor Kazimierz Wrześniewski. It concerns the role of curiositytrait in the dynamics of changes in coping and quality of life after a heart attack. The study was attended by 222 people after a heart attack, of whom 140 participated in the three stages of the study: at the beginning and at the end of cardiac rehabilitation and a year after leaving the resort. The participants aged 24-64 years. Curiosity-trait was (...) measured by Spielberger and Wrześniewski’s STPI questionnaire. To assess coping strategies a modified version of the COPE by Carver et al., was used. The specific and general quality of life were measured by the Polish adaptations of MacNew and NHP questionnaires. The level of curiosity-trait significantly differentiated changes in the dynamics of positive reinterpretation, problem solving and resignation, but did not affect the change in quality of life within the year after a heart attack.

In lieu of an abstract, here is a brief excerpt of the content:The Institute of Medicine’s Report on Non-Heart-Beating Organ TransplantationRoger Herdman (bio), Tom L. Beauchamp (bio), and John T. Potts Jr. (bio)In December 1997, the Institute of Medicine (IOM) released a report on medical and ethical issues in the procurement of non-heart-beating organ donors. This report had been requested in May 1997 by the Department of Health and Human Services (DHHS). We will here describe the genesis of the IOM (...) report, the medical and moral concerns that led the DHHS to sponsor it, the process of producing it, and its conclusions. The analyses, findings, and recommendations of the report are also reviewed, in particular the central issues that led to suggestions for policy changes.Transplantation BackgroundAs a first step, some background in the relevant aspects of organ transplantation will prove useful. For the purposes of this analysis, “transplantation” involves the transfer of cells, tissues, or solid organs from one human to another to replace the structure or function of comparable body components that, through injury or disease, are defective or of inadequate function. The IOM report deals with solid organs, primarily kidneys and livers, whose blood supply is reconnected in the organ recipient, in contrast to cells, like bone marrow, and tissues, like corneas. A variety of donor types exists for organ transplantation, each with particular medical and scientific conditions.Living donors are healthy (and usually genetically related) individuals who volunteer to provide either a whole, paired organ such as a kidney or a section of an organ such as a liver. Cadaver donors are individuals who have died and from whom a full array of organs can be taken. “Heart-beating” cadaver donors are individuals who have suffered “brain death,” that is, irreversible cessation of function of the whole brain including the brain stem; and “non-heart-beating” donors (NHBDs) are individuals who are ill or injured, but not “brain dead,” and who have suffered cardiopulmonary death, that is, irreversible cessation of cardiac and respiratory function. NHBDs can be “controlled,” which means that [End Page 83] they can be sustained by artificial life support systems until a medical and family decision is made to terminate futile life support. This can be done at a scheduled time and in a controlled manner, and organs can then be recovered for transplantation. NHBDs can also be “uncontrolled,” which means that their hearts and breathing have stopped through disease or injury at an unexpected time or in an uncontrolled manner, and they cannot be resuscitated; the organs of some individuals of this description can be recovered for transplantation. The IOM report focused on both controlled and uncontrolled NHBDs and on problems specific to them.The questions that were asked and addressed in the IOM report became current and salient beginning in 1992 with the establishment of the University of Pittsburgh “Policy for the Management of Terminally Ill Patients Who May Become Organ Donors After Death.” This policy addressed controlled NHBDs and the ethical questions raised by their use; much of the discussion was reported in the June 1993 special issue of the Kennedy Institute of Ethics Journal. Public notice and anxiety about some of these concerns were sharpened and refocused by national and local media allegations of improper treatment of donors at the Cleveland Clinic in 1997, specifically premature—i.e., antemortem—recovery of organs and administration of drugs that allegedly might hasten donor death.The DHHS Request for StudyIt is not surprising that several federal actions would be taken in response to these events. Some, such as the results of a transplantation task force, remain largely internal to DHHS at this writing. Others are public, such as the IOM study of the NHBD situation. In May 1997, the DHHS initiated contacts with the IOM with the goal of exploring federal concerns about the medical and ethical treatment of NHBDs, in particular the allegations directed at the Cleveland Clinic.The DHHS response should be understood in at least three contexts. First, living donors and uncontrolled NHBDs were essentially the only donor types in the early days of transplantation in the United States. The technologies, ethics, and social acceptance of controlling and terminating life support for... (shrink)

At various points in his work on physiology and medicine, Descartes refers to a “principle of life.” The exact term changes—sometimes, it is the “principle of movement and life”, sometimes the “principle underlying all [the] functions” of the body —but the message seems consistent: the phenomena of living bodies are the product of a single, underlying principle. That principle is generally taken to be cardiac heat.1 The literature has, quite reasonably, taken this message at face value. Thus, Shapiro: (...) “Descartes insists again and again that the human body is properly to be described as a machine whose workings are […] driven by the heat in the heart that... (shrink)

An individual’s right to refuse life-sustaining treatment is a fundamental expression of patient autonomy; however, supporting this right poses ethical dilemmas for healthcare providers when the patient has attempted suicide. Emergency physicians encounter patients who have attempted suicide and are likely among the first medical providers to face the dilemma of honoring the patient’s DNR or intervening to reverse the effects of potentially fatal actions. We illustrate this issue by introducing a case example in which the DNR of a terminally (...) ill woman was not honored because the cause of her cardiac arrest was suicide. We argue that although a terminal diagnosis should change the way health care providers respond to a suicide attempt, many of the theoretical underpinnings for how one should treat suicide attempts—especially the criterion of external reasonability, that is the action to withhold or withdraw life-sustaining measures is reasonable independent of the precipitating event—are common to all situations :3–12, 2013). The presumption that patients who attempt suicide lack capacity due to acute mental illness is flawed because it fails to account for a competent individual’s reasonable preference to not be forced to live in an unbearable, terminal condition. In states without legislation allowing physician aid in dying, patients and providers must grapple with these limitations on a case-by-case basis. In cases where the patient has a limited life expectancy and there is not concern for psychiatric illness as the primary cause of the suicidal action, we argue that the negative right to refuse life-sustaining treatment should prevail.

The Brain Death Reconsidered – Is It a Tenable Concept? Since 1968 it has been recognized in the medical practice that irreversible coma connected with apnea can serve as a criterion of human death. This approach was first introduced in the so called Harvard Protocol. As a result of the work of this commission, the brain-based criteria of human death were quickly legally introduced in America and in most countries in the world. The only symptom on which death can be (...) pronounced is, according to this new definition, the absence of spontaneous brain function. However, the acceptance of the new definition of death did not eliminate the old one completely. In many states both old and new definitions of death are legally valid. Practically, in these countries the alternative definition of death functions alongside the old one and diagnosis of death can be based both on the cardiac/respiratory and brain symptoms. One of the few exceptions proved to be Japan. The law in this country does not provide a uniform answer to the question of what human death is. Instead, it allows people to choose between traditional death and brain death. The law states that if a person wants to be an organ donor after brain death has occurred, he or she must record that intention on a donor card or label beforehand. Those who object to brain death and transplantation do not need donor cards. They are considered to be alive until the heart stops beating. In this way the Japanese law respects the opinion of 20-40% of the society who do not believe in the brain death. The opinion of the same percentage of people in Western societies who oppose BD is ignored by their legal systems. Initially the concept of BD did not cause a lot of controversy but this situation changed in the nineties of the last century. Since then many authors have criticized the validity of the brain-based criteria of death. They maintain that it is impossible to declare the absence of all the functions of the whole brain on the basis of the clinical tests supposed to detect it. There may be present some level of consciousness in brain death (BD) patients and therefore, they may feel pain. It is significant that 27% of the members of the teams which perform the excision of the heart for transplantation think that they are killing a living person and that in many countries during this operation a normal general anesthesia is required because of the vivid reaction of the body of the patient. The opponents of the brain death theory stress that the accurate examination of the so-called brain dead persons shows the persistence of the functions of significant parts of their brains. There are EEG waves recorded in 20-40% of BD patients. Event related potentials (ERP) show the reaction to verbal and non-verbal stimuli and the hormone production by the brain tissue can be detected in many BD people. The proper treatment could not only significantly prolong lives of the BD patients, but around 60% of possible donors with the lowest result of 3 in Glasgow Coma Scale could be restored to normal life if their brain edema is properly treated. This treatment should be based on the therapeutic hypothermia connected with the application of the thyroid hormones, whose level is usually too low in the patients with the brain injury. There is a growing lack of consensus regarding the issue of brain death, especially among physicians. Some regard brain death as a biological one, some as the death of the person but not of the human body, and the rest, as a definition accepted by the society, which doesn’t require other legitimacy than the freely chosen criteria. The brain death concept is also criticized from the philosophical point of view. The strength of the brain death theory was based on the premise that the brain is the integrating center of the body. According to this argument, the death of the brain means that the organism ceases to exist for it is no longer a functioning whole. To this argument the opponents of the brain death concept say that this question is not a question a priori but an empirical one and that the empirical data validate the opposite opinion, which says that the bodies of brain dead patients are alive. Some widely known cases show that even the real death of the entire brain means the death of the body and, therefore, may not signify the death of a human person. The integration of the body is the function of the organism as a whole and not of a single organ, even if this organ is the brain. This point of view can be confirmed by the opinion of St. Thomas Aquinas who says that the soul is primarily and per se connected with the body as a whole as the proportionate perfectible and only secondarily with the parts of the body, according to their ordination to the whole. So, the death of any single organ does not preclude the union of the soul with the rest of the body as a living whole. Moreover, the terms such as “consciousness” and “person” should not be identified. The term such as “human living nonpersons”, proposed by some bioethicists and referring to the people without consciousness has not been accepted in the official documents concerning BD. Bodies of the BD people are alive, therefore, it is not right to use the term “brain death” to describe the state of these patients, but rather the term “brain failure” should be used. As the result, according to some authors, the dead donor rule should be abolished. The Catholic Church stresses the sacredness of the human life from the beginning to the end. Therefore She requires that there be no doubts that the donor in BD is really dead. Because of the lack of consensus among physicians, philosophers and theologians, the popes John Paul II and Benedict XVI decided to continue the scientific research and discussion concerning BD between the representatives of various disciplines. Keywords: brain death, brain edema, global ischemic penumbra, therapeutic hypothermia, consciousness, person, substantial form. (shrink)

: The Siminoff, Burant, and Youngner study in Ohio is strikingly consistent with data from a national study. Both suggest that there might be significant public acceptance of future policies that violate the dead donor rule, or that further extend the boundary between life and death to include brain-damaged patients short of "brain death." Experience with donation suggests that many individuals would donate their loved ones' organs when they have concluded that the brain injury is not survivable, even if all (...) the criteria for "brain death" are not met. It would be very helpful to have research on those who have gone through a real-life clinical situation. Based on the findings of this study and the increasing demand for organs, it may be appropriate for public policy to allow for ways to increase organ procurement from individuals who are not fully "brain dead" beyond the current method of procurement after cardiac death, but any change in this area should go slowly and with significant public input.

A significant portion of newborns cared for in the neonatal intensive care unit or other ICUs, such as the cardiac ICU, have a medical condition with a genetic component, including congenital malformations, the leading cause of death in the NICU. In many cases, however, it is not clear which condition the child has or what can be done to help him or her. Genomic sequencing of sick newborns has the potential to bypass the prolonged journey to a diagnosis, improving (...) the medical care of individual infants. Sequencing also has the potential to benefit others beyond the child whose genome is sequenced and his or her immediate family. Sequence data from sick newborns will expand medicine's understanding of genetic diseases, leading to improvements in clinicians’ ability to counsel family and to provide even more targeted care. Not only will more frequent use of sequencing lead to discovery of new genes; it will also provide unique insights into the full spectrum of known Mendelian genetic diseases, so‐called phenotypic expansion, when a gene previously recognized as associated with a phenotype is found to be associated with an expanded set of clinical features. Genetic and environmental changes that modify the expression of a genetic disease may also be elucidated. (shrink)

Inherited disorders of ion‐channels are associated with paroxysmal dysfunction of excitable tissues and manifest as diseases of the brain, heart and skeletal muscle. These so‐called channelopathies have now been described for most of the major categories of voltage‐dependent ion‐channels including those selectively permeable to sodium. Sodium channelopathies affecting the heart and brain are reviewed in this essay. They show striking differences and similarities including, for example, their responsiveness to changes in body temperature and sleep state. They represent a paradigm (...) for efforts to trace disturbed behaviour of physiological systems back to its molecular origins and understanding their molecular basis may provide clues to important health issues such as cardiac side effects of drugs and response to medication used to treat epilepsy.

The development of modern programmable pacemaker-systems has led to a series of questions which until now have apparently not existed in the treatment of cardiac rhythm disturbances. These questions touch especially on the problem of whether the relation which usually exists between a diagnostic step and its therapeutic consequence, namely its therapeutic relevance, is abolished or at least changed.

Using dimensional analysis, we demonstrate that it is possible to quantify changes in the topological structure of cardiac dynamics over long periods of time. A method was developed to calculate a dimension-like measure (referred to here as apparent dimension) from a correlation algorithm within a data window of 500 heart beats which is moved in equidistant steps over the time series of the RR intervals over 24 hours. The correspondence between the apparent dimension and the correlation dimension was (...) tested using artificial data sequences. Furthermore 24 hour electrocardiographic recordings of two healthy subjects and of a patient with acute myocardial infarction were examined. The reliability of the analysis could be demonstrated and changes in dimension reflecting physiological as well as pathophysiological changes were observed. (shrink)

The quality of the animal-human relationship and, consequently, the welfare of animals can be improved by gentle interactions such as stroking and talking. The perception of different stimuli during these interactions likely plays a key role in their emotional experience, but studies are scarce. During experiments, the standardization of verbal stimuli could be increased by using a recording. However, the use of a playback might influence the perception differently than ‘live’ talking, which is closer to on-farm practice. Thus, we compared (...) heifers’ (n = 28) reactions to stroking while an experimenter was talking soothingly (‘live’) or while a recording of the experimenter talking soothingly was played (‘playback’). Each animal was tested three times per condition and each trial comprised three phases: pre-stimulus, stimulus (stroking and talking) and post-stimulus. In both conditions, similar phrases with positive content were spoken calmly, using long low-pitched vowels. All tests were video recorded and analyzed for behaviors associated with different affective states. Effects on the heifers’ cardiac parameters were assessed using analysis of heart rate variability. Independently of the auditory stimuli, longer durations of neck stretching occurred during stroking, supporting our hypothesis of a positive perception of stroking. Observation of ear positions revealed longer durations of the back up position and less ear flicking and changes of ear positions during stroking. The predicted decrease in HR during stroking was not confirmed; instead we found a slightly increased mean HR during stroking with a subsequent decrease in HR, which was stronger after stroking with live talking. In combination with differences in HRV parameters, our findings suggest that live talking might have been more pleasurable to the animals and had a stronger relaxing effect than ‘playback’. The results regarding the effects of the degree of standardization of the stimulus on the variability of the data were inconclusive. We thus conclude that the use of recorded auditory stimuli to promote positive affective states during human-animal interactions in experimental settings is possible, but not necessarily preferable.

The current study used cross-modal oddball tasks to examine cardiac and behavioral responses to changing auditory and visual information. When instructed to press the same button for auditory and visual oddballs, auditory dominance was found with cross-modal presentation slowing down visual response times more than auditory response times (Experiment 1). When instructed to make separate responses to auditory and visual oddballs, visual dominance was found with cross-modal presentation decreasing auditory discrimination and participants also made more visual-based than auditory-based errors (...) on cross-modal trials (Experiment 2). Experiment 3 increased task demands while requiring a single button press and found evidence of auditory dominance, suggesting that it is unlikely that increased task demands can account for the reversal in Experiment 2. Auditory processing speed was the best predictor of auditory dominance, with auditory dominance being stronger in participants who were slower at processing the sounds, whereas, auditory and visual processing speed and baseline heart rate variability did not predict visual dominance. Examination of cardiac responses that were time-locked with stimulus onset showed cross-modal facilitation effects, with auditory and visual discrimination occurring earlier in the course of processing in the cross-modal condition than in the unimodal conditions. The current findings showing that response demand manipulations reversed modality dominance and that time-locked cardiac responses show cross-modal facilitation, not interference, suggest that auditory and visual dominance effects may both be occurring later in the course of processing, not from disrupted encoding.

Because complex organs taken from unequivocally dead people are not suitable for transplantation, human death has been redefined so that it can be certified at some earlier stage in the dying process and thereby make viable organs available without legal problems. Redefinitions based on concepts of "brain death" have underpinned transplant practice for many years although those concepts have never found universal philosophical acceptance. Neither is there consensus about the clinical tests which have been held sufficient to diagnose the irreversible (...) cessation of all brain function – or as much of it as is deemed relevant – while the body remains alive. For these reasons, the certification of death for transplant purposes on "brain death" grounds is increasingly questioned and there has been pressure to return to its diagnosis on the basis of cardiac arrest and the consequent cessation of blood circulation throughout the body. While superficially a welcome return to the traditional and universally accepted understanding of human death, examination of the protocols using such criteria for the diagnosis of death prior to organ removal reveals a materially different scenario in which the circulatory arrest is not certainly final and purely nominal periods of arrest are required before surgery begins. Recognizing the probably unresolvable conflict between allowing enough time to pass after truly final circulatory arrest for a safe diagnosis of death and its minimization for the sake of the wanted organs, Verheijde and colleagues follow others in calling for the abandonment of the "dead donor rule" and the enactment of legislation to permit the removal of organs from the dying, without pretence that they are dead before that surgery. While it may be doubted whether such a "paradigm change" in the ethics of organ procurement would be accepted by society, their call for its consideration as a fully and fairly informed basis for organ donation is to be applauded.

BackgroundThere is much overlap among the symptomology of autistic spectrum disorders, obsessive compulsive disorders, and alexithymia, which all typically involve impaired social interactions, repetitive impulsive behaviors, problems with communication, and mental health.AimThis study aimed to identify direct and indirect associations among alexithymia, OCD, cardiac interoception, psychological inflexibility, and self-as-context, with the DV ASD and depression, while controlling for vagal related aging.MethodologyThe data involved electrocardiogram heart rate variability and questionnaire data. In total, 1,089 participant's data of ECG recordings of healthy (...) resting state HRV were recorded and grouped into age categories. In addition to this, another 224 participants completed an online survey that included the following questionnaires: Yale-Brown Obsessive Compulsive Scale ; Toronto Alexithymia Scale 20 ; Acceptance and Action Questionnaire ; Depression, Anxiety, and Stress Scale 21 ; Multi-dimensional Assessment of Interoceptive Awareness Scale ; and the Self-as-Context Scale.ResultsHeart rate variability was shown to decrease with age when controlling for BMI and gender. In the two SEMs produced, it was found that OCD and alexithymia were causally associated with autism and depression indirectly through psychological inflexibility, SAC, and ISen interoception.ConclusionThe results are discussed in relation to the limitations of the DSM with its categorical focus of protocols for syndromes and provide support for more flexible ideographic approaches in diagnosing and treating mental health and autism within the Extended Evolutionary Meta-Model. Graph theory approaches are discussed in their capacity to depict the processes of change potentially even at the level of the relational frame. (shrink)

The present study examined deep gray matter perfusion in neonates with congenital heart disease (CHD) with arterial spin labeling magnetic resonance imaging preoperatively. We found that neonates with cyanotic CHD showed lower right thalamus compared with controls and lower right basal ganglia perfusion compared with acyanotic CHD. When the CHD group was assessed as a whole, it showed slightly decreased left thalamus perfusion compared with controls. The results suggest that cardiac physiology plays a crucial part in changes in (...) regional cerebral perfusion. Perfusion with arterial spin labeling may be a useful marker of high risk for impaired cerebral blood flow auto-regulation and cerebral hypoperfusion in neonates with CHD. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethan’s GiftMichelle BurgessEthan was your average boy next door. He loved everything most 8–year–old boys do including playing baseball, swimming, and watching his favorite baseball team, the Philadelphia Phillies.On December 3rd 2008, life for our family changed forever when Ethan was diagnosed with Diffuse Intrinsic Pontine Glioma, a rare inoperable brainstem tumor. DIPG is in essence a death sentence. There are no survivors and life expectancy after diagnosis is (...) only 9–12 months. Our family was devastated.For the next 14 months, we lived life to the fullest, never taking a single moment or day for granted. As Ethan’s condition worsened, and it became clear that he was close to passing, I spoke with Ethan’s doctor about my desire to be able to donate Ethan’s corneas and his brain tumor for research. He informed me that because of Ethan’s type of tumor that he may be a candidate for donation of other organs as well if that is something we wanted to do.Knowing that there was nothing we could do to save Ethan, it was something that we felt we could do to help others so we decided to explore the option of donating Ethan’s other organs. We were put in contact with the Gift of Life.Two representatives from Gift of Life came to our home and discussed at length with us what would have to happen to make organ donation possible at the time of Ethan’s passing. Specifically that Ethan would have to pass away at the hospital and in the operating room. This was very different than the hospice environment that we had planned. They also had told us that Ethan was only the second young person that they had ever dealt with that the families had planned ahead of time to donate organs. The other person was a teenager who planned his own organ donation.On January 26th 2010, Ethan’s pain had become unmanageable at home and his breathing had become very labored. I spoke with his oncologist and he advised me to bring Ethan to the hospital to try and get his pain under control.We loaded Ethan up in the car for the one–hour car ride to the hospital. On the way to the hospital Ethan fell asleep while being cuddled by me in the backseat. When we arrived at the hospital we noticed that his fingers and toes had turned purple. The nurses immediately checked his oxygen and it had fallen to only 10 %.The doctors advised that he had slipped into a coma in the car, one that he would never awake from. He was immediately placed on life support. A scan was done and it was evident that the progressing tumor was placing pressure on the areas of the brain that controlled basic life functions such as breathing. Ethan could not recover.The decision was made to begin to look for recipients for Ethan’s organs. Because Ethan had not reached the point of brain death, his donation would have to be a post cardiac death transplant, meaning, life support would be removed, when his heart stopped beating and he passed away, the organ procurement would begin. However, he [End Page E1] would not be able to donate his heart. This was very sad for us, knowing how strong his little heart was, but we did understand the process.On January 28th 2010, our family spent the day saying goodbye to Ethan. Even though he could not respond, we know that he could hear us. The nurse was wonderful, doing everything possible to accommodate our large family and despite all the tubes and machines, make it so that I could cuddle with my little boy one last time.Ethan was moved to the operating room and with his stepfather and I on one side and his father and stepmother on the other, life support was removed. Watching my son take his last breath, while I held his hand, kissed his cheeks, told him I loved him and that it was okay to let go and go to Heaven was the hardest moment of... (shrink)

Most emotion theories recognise the importance of the body in expressing and constructing emotions. Focusing beyond the face, the present research adds needed empirical data on the effect of static full body postures on positive/negative affect. In Studies 1 (N = 110) and 2 (N = 79), using a bodily feedback paradigm, we manipulated postures to test causal effects on affective and physiological responses to emotionally ambiguous music. Across both studies among U.S. participants, we find the strongest support for an (...) effect of bodily postures that are expansive and oriented upward on positive affect. In addition, an expansive and upward pose also led to greater cardiac vagal reactivity but these changes in parasympathetic activity were not related to affective changes (Study 2). In line with embodied theories, these results provide additional support for the role of postural input in constructing affect. Discussion highlights the relevance of these findings for the study of religious practices during which the postures studied are often adopted. (shrink)

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (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.
