RESUMEN

Certain organoid subtypes are particularly sensitive. We explore whether moral intuitions about the heartbeat warrant unique moral consideration for newly advanced contracting cardiac organoids. Despite the heartbeat's moral significance in organ procurement and abortion discussions, we argue that this significance should not translate into moral implications for cardiac organoids.

RESUMEN

BACKGROUND: The use of human bodies for anatomy education and research forms an integral part of the training of health professionals around the world. However, the ethical acquisition of human remains for this purpose has been a challenge in many countries, particularly for those on the African continent. South African institutions have however, been able to progressively transition to a more ethical approach to human body acquisition. The aim of the current study was to investigate the provenance of human bodies and the number used in South African health sciences institutions during the period 2017-2021. METHODS: an online self-administered anonymised questionnaire was circulated to all health sciences institutions in South Africa. Questions were focused on establishing the provenance and the associated number of bodies and body donor programmes. RESULTS: responses were received from thirteen of the fourteen South African institutions. All thirteen institutions use human bodies for teaching and research, with the majority of the institutions being reliant on bequests (77%) and family donations (62%), and less on unclaimed remains (46%). Most institutions have established body donor programmes. Four institutions were negatively affected by the effects of the pandemic. Memorial services, which continued during the pandemic, were conducted by eight of the thirteen institutions. CONCLUSION: South Africa is leading the transition to the ethical acquisition of human remains on the African continent. It is hoped that South African institutions will soon transform to the exclusive sourcing of bodies through willed donation and provide guidance and support for the other countries on the continent.

RESUMEN

According to the mainstream bioethical stance, death constitutes the termination of an organism. This essay argues that such an understanding of death is inappropriate in the usual context of determining death, since it also has a social bearing. There are two reasons to justify this argument. First, the mainstream bioethical definition generates an organismal superposition challenge, according to which a given patient in a single physiological state might be both alive and dead, like Schrödinger's cat. Therefore, there is no clear answer as to whether organ retrieval from a brain-dead patient is an act of killing or not. Second, when combined with the dead donor rule, the mainstream position in the definition of death might lead to ethically unacceptable verdicts, since there is a discrepancy between terminating an organism and depriving someone of moral status.

RESUMEN

In a workshop sponsored by the U.S. National Heart, Lung, and Blood Institute, experts identified current knowledge gaps and research opportunities in the scientific, conceptual, and ethical understanding of organ donation after the circulatory determination of death and its technologies. To minimize organ injury from warm ischemia and produce better recipient outcomes, innovative techniques to perfuse and oxygenate organs postmortem in situ, such as thoracoabdominal normothermic regional perfusion, are being implemented in several medical centers in the US and elsewhere. These technologies have improved organ outcomes but have raised ethical and legal questions. Re-establishing donor circulation postmortem can be viewed as invalidating the condition of permanent cessation of circulation on which the earlier death determination was made and clamping arch vessels to exclude brain circulation can be viewed as inducing brain death. Alternatively, TA-NRP can be viewed as localized in-situ organ perfusion, not whole-body resuscitation, that does not invalidate death determination. Further scientific, conceptual, and ethical studies, such as those identified in this workshop, can inform and help resolve controversies raised by this practice.

RESUMEN

PURPOSE OF REVIEW: The adoption of brain death played a crucial role in the development of organ transplantation, but the concept has become increasingly controversial. This essay will explore the current state of the controversy and its implications for the field. RECENT DEVELOPMENTS: The brain death debate, long limited to the bioethics community, has in recent years burst into the public consciousness following several high-profile cases. This has culminated in the reevaluation of the Uniform Determination of Death Act (UDDA), which is in the process of being updated. Any change to the UDDA has the potential to significantly impact the availability of organs. SUMMARY: The current update to the UDDA introduces an element of uncertainty, one the brain death debate had not previously had.

RESUMEN

BACKGROUND: Body donation is integral to anatomy education, but procurement can be ethically fraught. While voluntary donation is preferred, the use of unclaimed bodies, although considered unethical, is a primary means for body procurement in some countries. This mixed methods study examined historical trends and anatomy technical staff perspectives on body donation in two Zimbabwean medical schools. METHODOLOGY AND MAIN FINDINGS: In Phase 1, 194 cadaver paper records from January 1984 to January 2021 were reviewed. Unclaimed bodies accounted for 67% while 33% (all white Zimbabweans) were voluntarily donated. Most cadavers were black Africans (62.4%) followed by white Zimbabweans (34.0%). Race was not indicated in seven (3.6%) records. In Phase 2, semi-structured interviews were conducted with seven technicians responsible for sourcing cadavers at the two institutions. Data were thematically analysed resulting in the development of eight themes, arranged into three domains. Cadaver procurement themes related to (1) cadaver source, (2) adherence to procurement guidelines, (3) screening for suitability, and (4) cultural and religious beliefs. Cadaver embalmment focused on (5) embalming practices, and (6) hospital mortuary-based embalming. Finally, (7) disposal processes and (8) resource constraints were found to influence cadaver disposal practices. CONCLUSIONS: Contrary to best practice, there is continued reliance on the use of unclaimed bodies to support anatomy education in the two Zimbabwean medical schools. Improving the ethical sourcing of bodies requires increased efforts to educate all Zimbabweans, especially the black majority, about the role and importance of voluntary body donation in medical education. Additionally, well-structured, and well-resourced body donation programs could enhance ethical procurement.

RESUMEN

Kidney markets are prohibited in principle because they are assumed to undermine the seller's dignity. Considering the trade-off between saving more lives by introducing regulated kidney markets and preserving the seller's dignity, we argue that it is advisable to demand that citizens restrain their own moral judgements and not interfere with the judgements of those who are willing to sell a kidney. We also argue that it is advisable not only to limit the political implications of the moral argument of dignity concerns toward a market-based solution but also to re-evaluate the dignity argument itself. First, if the dignity argument is to be given normative force, it must also consider the dignity violation of the potential transplant recipient. Second, there seems to be no compelling notion of dignity that demonstrates why it is morally permissible to donate but not to sell a kidney.

RESUMEN

This article provides an in-depth ethical analysis of living donor uterus transplantation, incorporating clinical, psychological, and qualitative study data into the discussion. Although the concept of living organ donors as patients in their own right has not always been present in the field of transplantation, this conceptualization informs the framework for living donor ethics that we apply to living uterus donation. This framework takes root in the principles of research ethics, which include respect for persons, beneficence, and justice. It incorporates an analysis based on eight potential vulnerabilities of living donors: capacitational, juridic, deferential, social, medical, situational, allocational, and infrastructural. Finally, it recognizes that special relationships-such as that of the living donor advocate with the potential donor-require special responsibilities, including identifying vulnerabilities and engaging donors in a shared decision-making process. Directed and non-directed uterus donors require separate ethical analyses because their different relationships with recipients will influence the types of vulnerabilities, they are subject to as well as the potential benefits they may gain from donation.

RESUMEN

Organ shortage is a major survival issue for millions of people worldwide. Globally 1.2 million people die each year from kidney failure. In this paper, we critically examine and find lacking extant proposals for increasing organ supply, such as opting in and opt out for deceased donor organs, and parochial altruism and paired kidney exchange for live organs. We defend two ethical solutions to the problem of organ shortage. One is to make deceased donor organs automatically available for transplant without requiring consent from the donor or their relatives. The other is for society to buy nonvital organs in a strictly regulated market and provide them to people in need for free.

RESUMEN

Living kidney donation is the most common type of living-donor transplant. Italian guidelines allow the living donations from emotionally related donors only after clear and voluntary consent expressed by both the donor and the recipient involved. Living donation raises ethical and legal issues because donors voluntarily undergo a surgical procedure to remove a healthy kidney in order to help another person. According to the Italian standards, the assessment of living donor-recipient pair has to be conducted by a medical "third party", completely independent from both the patients involved and the medical team treating the recipient. Starting from the Hospital "Città della Salute e della Scienza" of Turin (Italy) experience, including 116 living kidney donations, the Authors divided the evaluation process performed by the "Third-Party" Commission into four stages, with a particular attention to the potential donor. Living donation procedures should reflect fiduciary duties that healthcare providers have toward their patients, originating from the relationship of trust between physician and patient. In addition to that, the social implications are enormous if one considers the worldwide campaigns to promote public awareness about organ donation and transplantation, and to encourage people to register their organ donation decisions. The systematic process proposed here can be a tool that proactively reduces and controls the risks of coercion, organ trafficking, vitiated consent, insufficient weighting of donative choice, that could arise especially in donors involved in living kidney donation.

RESUMEN

Abstract In medical clinical practice, organ transplantation is mainly applied to patients with end-stage organ lesions and organ failure. However, with the development of organ transplantation, many ethical issues and controversies have arisen. From the perspective of bioethics, the article compares the relevant ethical and legal regulations of organ transplantation in various countries. Due to the complexity of the real situation, many ethical dilemmas arise in organ transplantation in China. The article analyzes and researches three aspects of organ donation, distribution, and trading, and finds that there are various ethical problems in these three aspects of organ transplantation in China, such as whether the principle of presumed consent is ethical, whether brain death is legalized, the selection and determination of transplant patients, and whether human organ trading is legalized, etc. With the help of the four principles of bioethics and the current development of organ transplantation in China, the article proposes that organ transplantation in China should follow four ethical principles: the principle of respect for life, the principle of do no harm/benefit, the principle of respect for autonomy, and the principle of justice, in order to provide a defense for the legitimacy of organ transplantation.


Resumen En la práctica clínica médica, el trasplante de órganos se aplica principalmente a los pacientes con lesiones orgánicas en fase terminal y con insuficiencia orgánica. Sin embargo, con el desarrollo del trasplante de órganos, han surgido muchas cuestiones éticas y controversias. Desde la perspectiva de la bioética, el artículo compara las normas éticas y jurídicas pertinentes del trasplante de órganos en varios países. Debido a la complejidad de la situación real, surgen muchos dilemas éticos en el trasplante de órganos en China. El artículo analiza e investiga tres aspectos de la donación, la distribución y el comercio de órganos, y constata que hay varios problemas éticos en estos tres aspectos del trasplante de órganos en China, como si el principio del consentimiento presunto es ético, si la muerte cerebral está legalizada, la selección y determinación de los pacientes de trasplante y si el comercio de órganos humanos está legalizado, etc. Con la ayuda de los cuatro principios de la bioética y el desarrollo actual del trasplante de órganos en China, el artículo propone que el trasplante de órganos en China debe seguir cuatro principios éticos: el principio de respeto a la vida, el principio de no hacer daño/beneficio, el principio de respeto a la autonomía y el principio de justicia, con el fin de proporcionar una defensa de la legitimidad del trasplante de órganos.

RESUMEN

INTRODUCTION: Corneal transplantation is the only treatment option for corneal blindness to restore sight. However, there is a disproportionate imbalance between the demand and supply of corneal tissue in Ethiopia. This is because accessing corneal tissue is reliant on people who are willing to donate corneas after death. OBJECTIVE: This study aimed to assess the proportion of willingness to donate cornea and associated factors among adult patients attending at University of Gondar comprehensive and specialized hospital. METHOD: Institutional based cross-sectional study was conducted from July 13 to July 28, 2020, through a face-to-face interview. A total of 451 samples were selected using systematic random sampling. The data were entered into Epidemiological information version 7 and exported to statistical package for social science version 20 for formal analysis. Variables with a P-value of < 0.20 in a bi-variable logistic regression were entered into the multivariable logistic regression and those variables with a p-value of < 0.05 were taken as statistically significant. The strength of association was shown using the odds ratio with a 95% confidence interval. RESULT: A total of 408 adults participated in this study with a response rate of 90% and the proportion of willingness to donate cornea was 179(43.90%). Participants who had a religious belief in Christianity (AOR = 3.23 (95% CI: 1.09-9.57)) and good knowledge about corneal donation (AOR = 5.45(95%CI: 2.69-11.18)) were positively associated with the willingness of corneal donation. On the other side, the age group above 43 years (AOR = 0.31(95% CI: 0.11-0.89) was negatively associated with the willingness of corneal donation. CONCLUSION: The proportion of willingness to donate cornea 43.9% among participants attending Gondar University Comprehensive and Specialized Hospital. Age group greater than 43 years, religion of Christianity and good knowledge were associated with the willingness of corneal donation.
