Non-identified and directed embryo donation: a questionnaire study on donor and recipient perspectives.

With the growing challenge of abandoned surplus embryos in the ART arena, and the limited traction of embryo donation as a viable embryo disposition choice, it is important to better understand barriers to wider adoption of this opportunity. We aim to learn about perspectives and experience of participants in directed and non-identified embryo donation programmes. This was a longitudinal cohort survey study, of all participants in an embryo donation programme in a single university affiliated clinic between 2016 and 2020. Clinical data were extracted from counselling reports. Based on these data, non-identified online questionnaires were constructed and refined via Delphi procedure for face and content validity. Sixty-five online questionnaires were emailed between March-April 2021. Descriptive statistics, cross-tabulation, Fisher's exact test and t-test were used for analyses. Source of patient awareness, factors influencing the decision-making process, patient perspective and satisfaction were explored. The response rate was 67.2%. Most participants in the non-identified programme learned of it through their treating physicians, whereas most participants in the directed programme learned of it online. The main driver to donate across both cohorts was wanting to give others the opportunity to experience the joy of parenthood. Overall, 45% described moderate to marked difficulty in decision making related to donating their embryos, and this did not differ between cohorts. Non-identified donors reported feeling highly attached to the donated embryos more often than directed donors. Level of satisfaction was higher in the directed donation programme. Participants were more satisfied following directed than non-identified donation, and some even consider their counterparts as extended family. Our findings should be validated in various settings, and on larger samples.

Directed Organ Donation After Euthanasia.

Organ donation after euthanasia is performed in Belgium, the Netherlands, Canada and Spain. Directed deceased organ donation is currently possible under strict conditions in a limited number of countries, while it is currently not possible to opt for directed donation following euthanasia. While organ donation after euthanasia is a deceased donation procedure, directed organ donation after euthanasia could be seen as a deceased donation procedure with a living donation consent process. Therefore, directed organ donation after euthanasia is feasible on medical and ethical grounds. Strict safeguards should be in place, including the requirement of a pre-existing familial or personal relationship with the proposed recipient, without any evidence of coercion or financial gain.

Requests for Directed Blood Donations.

This Ethics Rounds presents a request for directed blood donation. Two parents feel helpless in the setting of their daughter's new leukemia diagnosis and want to directly help their child by providing their own blood for a transfusion. They express hesitancy about trusting the safety of a stranger's blood. Commentators assess this case in the setting of blood as a scarce community resource during a national blood shortage. Commentators review the child's best interest, future risks, and harm-benefit considerations. Commentators recognize the professional integrity, humility, and courage of the physician to admit his own lack of knowledge on the subject and to seek help rather than claim directed donation is not possible without further investigation into options. Shared ideals such as altruism, trust, equity, volunteerism, and solidarity are recognized as values relevant to sustainment of a community blood supply. Pediatric hematologists, a blood bank director, transfusion medicine specialists, and an ethicist conclude that directed donation is only justified by lower risks to the recipient in particular circumstances.

Cadaver surgical training in Japan: its past, present, and ideal future perspectives.

The framework for cadaver surgical training (CST) in Japan was established in 2012, based on the "Guidelines for Cadaver Dissection in Education and Research of Clinical Medicine" of the Japan Surgical Society (JSS) and the Japanese Association of Anatomists. Subsequently, the Ministry of Health, Labor and Welfare allocated funding from its budget for CST. By 2019, CST was being practiced in 33 medical schools and universities. Currently, the CST Promotion Committee of the JSS reviews each CST report submitted by medical schools and universities and provides guidance based on professional autonomy. This paper outlines the history of CST in Japan and presents a plan for its future. To sustain and oversee CST implementation, an operating organization, funded by stakeholders, such as government agencies, academic societies, and private companies, is needed.

Voucher-Based Kidney Donation and Redemption for Future Transplant.

Importance: Policy makers, transplant professionals, and patient organizations agree that there is a need to increase the number of kidney transplants by facilitating living donation. Vouchers for future transplant provide a means of overcoming the chronological incompatibility that occurs when the ideal time for living donation differs from the time at which the intended recipient actually needs a transplant. However, uncertainty remains regarding the actual change in the number of living kidney donors associated with voucher programs and the capability of voucher redemptions to produce timely transplants. Objective: To examine the consequences of voucher-based kidney donation and the capability of voucher redemptions to provide timely kidney allografts. Design, Setting, and Participants: This multicenter cohort study of 79 transplant centers across the US used data from the National Kidney Registry from January 1, 2014, to January 31, 2021, to identify all family vouchers and patterns in downstream kidney-paired donations. The analysis included living kidney donors and recipients participating in the National Kidney Registry family voucher program. Exposures: A voucher was provided to the intended recipient at the time of donation. Vouchers had no cash value and could not be sold, bartered, or transferred to another person. When a voucher was redeemed, a living donation chain was used to return a kidney to the voucher holder. Main Outcomes and Measures: Deidentified demographic and clinical data from each kidney donation were evaluated, including the downstream patterns in kidney-paired donation. Voucher redemptions were separately evaluated and analyzed. Results: Between 2014 and 2021, 250 family voucher-based donations were facilitated. Each donation precipitated a transplant chain with a mean (SD) length of 2.3 (1.6) downstream kidney transplants, facilitating 573 total transplants. Of those, 111 transplants (19.4%) were performed in highly sensitized recipients. Among 250 voucher donors, the median age was 46 years (range, 19-78 years), and 157 donors (62.8%) were female, 241 (96.4%) were White, and 104 (41.6%) had blood type O. Over a 7-year period, the waiting time for those in the National Kidney Registry exchange pool decreased by more than 3 months. Six vouchers were redeemed, and 3 of those redemptions were among individuals with blood type O. The time from voucher redemption to kidney transplant ranged from 36 to 155 days. Conclusions and Relevance: In this study, the family voucher program appeared to mitigate a major disincentive to living kidney donation, namely the reluctance to donate a kidney in the present that could be redeemed in the future if needed. The program facilitated kidney donations that may not otherwise have occurred. All 6 of the redeemed vouchers produced timely kidney transplants, indicating the capability of the voucher program.

The right to be forgotten versus the right to disclosure of gamete donors' id: ethical and legal considerations / El derecho al olvido frente al derecho a revelar la identificación de los donantes de gametos: consideraciones éticas y jurídicas / O direito ao esquecimento versus o direito à divulgação da identificação de dadores de gâmetas: considerações éticas e legais

Abstract: 15. The anonymity of gamete donors in the context of medically-assisted reproduction techniques (ART) and the right of the offspring to know their genetic or biological parents' identity is a controversial and widely debated topic in the scientific literature. The positions on the issue in each country are different. Sometimes they are in opposition to each other even in countries with strong similarities, such as those in the European Union (EU), in the framework of shared ethical values. Although some countries still enshrine the rule of anonymity, there is an undeniable tendency to guarantee the right to know one's origins by creating relevant exceptions or abolishing donor anonymity status altogether. 16. This article offers ethical and legal considerations of whether the so-called 'right to be forgotten' (RTBF) could be extended to include gamete donors' right to remain anonymous. This perspective goes against the general trend, certainly in Europe, of recognizing that offspring born from donor gametes have a right to access information relating to their genetic progenitors. The novel addition is to question whether the General Data Protection Regulation (GDPR) might provide fertile ground for questioning this approach, and effectively support those jurisdictions where anonymity is still possible.

Resumen: 20. El anonimato de los donantes de gametos en el contexto de las técnicas de reproducción médicamente asistida (RM) y el derecho de la descendencia a conocer su identidad genética o biológica es un tema controvertido y ampliamente debatido en la literatura científica. Las posiciones sobre el tema en cada país son diferentes. A veces se oponen entre sí, incluso en países con fuertes similitudes, como los de la Unión Europea (UE), en el marco de valores éticos compartidos. Aunque algunos países siguen consagrando la norma del anonimato, es innegable la tendencia a garantizar el derecho a conocer el propio origen creando las excepciones pertinentes o suprimiendo por completo el estatus de anonimato del donante. 21. Este artículo ofrece consideraciones éticas y jurídicas sobre si el llamado "derecho al olvido" podría ampliarse para incluir el derecho de los donantes de gametos a permanecer en el anonimato. Esta opinión es contraria a la tendencia general, ciertamente en Europa, de reconocer que los hijos nacidos de gametos donados tienen derecho a acceder a la información relativa a sus padres genéticos. La nueva adición consiste en debatir si el Reglamento general de protección de datos (RGPD) podría proporcionar un terreno fértil para cuestionar este enfoque y apoyar efectivamente a las jurisdicciones en las que el anonimato sigue siendo posible.

Este artigo oferece considerações éticas e legais sobre se o chamado "direito ao esquecimento" poderia ser alargado para incluir o direito dos dadores de gâmetas a permanecerem anónimos. Esta perspetiva vai contra a tendência geral, certamente na Europa, de reconhecer que os descendentes nascidos de gâmetas doadas têm o direito de aceder à informação relacionada com os seus progenitores genéticos. O novo aditamento é debater se o Regulamento Geral de Proteção de Dados (RGPD) poderá fornecer um terreno fértil para questionar esta abordagem, e apoiar efetivamente as jurisdições onde o anonimato ainda é possível.

Current Approaches to Desensitization in Solid Organ Transplantation.

Major advancements in the development of HLA antibody detection techniques and our understanding of the outcomes of solid organ transplant in the context of HLA antibody have occurred since the relevance of sensitization was first recognized nearly 50 years ago. Additionally, kidney paired donation programs (KPD) have become widespread, deceased donor allocation policies have changed, and several new therapeutic options have become available with promise to reduce HLA antibody. In this overview we aim to provide thoughtful guidance about when desensitization in kidney transplantation should be considered taking into account the outcomes of HLA incompatible transplantation. Novel therapeutics, desensitization endpoints, and strategies for future study will also be discussed. While most of our understanding about desensitization comes from studying kidney transplant candidates and recipients, many of the concepts discussed can be easily applied to desensitization in all of solid organ transplantation.

Revisit of Optimal Donor Number Estimation in the Hong Kong Bone Marrow Donor Registry.

High resolution typing of the HLA-DPB1 locus for patient who requested for hematopoietic stem cell transplantation (HSCT) workup has recently become mandatory by the National Marrow Donor Program (NMDP) in order to facilitate matching between donors and recipients for better outcomes. The likelihood of identifying HLA matched donors in Hong Kong, on top of the existing HLA-A, -B, -C, and -DRB1 loci, is revisited in this study. HLA-A, -B, -C, -DRB1 and -DPB1 genotypes of 5,266 volunteer unrelated Chinese donors from the Hong Kong Bone Marrow Donor Registry (HKBMDR), were included in this study. Matching models were employed to determine the matching probabilities for 10/10(DPB1) and 9/10(DPB1) HLA match. The matching probabilities are 20% at 10/10(DPB1) HLA match and 55% at 9/10(DPB1) match, based on the existing 130,000 donors in the HKBMDR. The likelihoods of match become 27% and 65% respectively, by increasing the registry to 250,000. However, if DPB T-cell-epitope (TCE) model is considered in the matching, the probability will increase to 46% at 10/10 DPB1 permissive mismatching. Our findings provide vital information about the future planning on the targeted recruitment size, HLA typing and search strategies of the donor registry and arose the transplant physicians' acceptability to 9/10(DBP1) or 10/10(DBP1) HLA match. Nevertheless, the marrow donor registry has planned for increasing the registry size and bringing down the age of recruited donors which will ultimately enhance patient outcome.

Laparoscopic Live Donor Nephrectomy: Single-Center Experience of 200 Consecutive Cases.

Background: Renal transplantation is the ideal treatment method for end-stage renal disease. Since deceased organ donation rates cannot meet the demand, live donor kidney transplantation (LDKT) is commonly performed worldwide. Laparoscopic donor nephrectomy (LDN) is currently the most commonly preferred minimally invasive donor nephrectomy technique. However, experienced surgeons should perform this procedure since the safety of the live donor is the priority in transplant practice. In this study, we aimed to investigate this procedure's safety at the hands of a surgeon during the transition period from open donor nephrectomy (ODN) to LDN. Methods: Data of the donors and recipients who underwent LDN and LDKT in Ankara Medicana Hospital between 2016 and 2019 were included in this study. Demographic, surgical, and immunological data of the donors and recipients were collected retrospectively. Donor data, including duration of surgery, warm ischemia time (WIT), complication rates, duration of hospital stay, and recipient data such as patient and graft survival rates, were compared with the published literature. Results: Two hundred donors and 200 recipients were included. The complication rate, surgical time, WIT at the donor site, and 1- and 3-year patient and graft survival rates were all comparable with the literature. Survival rates were irrespective of the relationship status of the donors with recipients. Conclusions: The LDN procedure can be safely performed by a surgeon with extensive laparoscopic surgery experience in general surgery cases and ODN.

Heart transplantation candidacy.

PURPOSE OF REVIEW: Timely referral of eligible candidates for consideration of advanced therapies, such as a heart transplantation or mechanical circulatory support is essential. The characteristics of heart transplantation candidates have changed significantly over the years, leading to a more complex evaluation process. The present review summarizes recent advances in the evaluation process for heart transplantation eligibility. RECENT FINDINGS: The heart transplantation allocation policy was recently reviewed in the USA in an effort to reduce waitlist mortality and to ensure fair geographic allocation of organs to the sickest patients. Moreover, patients with chronic infectious diseases, as well as malignancies, are being currently considered acceptable candidates for transplantation. Listing practices for heart transplantation vary between programmes, with a greater willingness to consider high-risk candidates at higher-volume centres. SUMMARY: The ultimate decision to place high-risk candidates on the heart transplantation waitlist should be based on a combination of quantitative and qualitative data analysis informed by clinical judgement, and the chronic shortage of organ donors makes this process an important ethical concern for any society. Future guidelines should discuss approaches to achieve fair organ allocation while preserving improved outcomes after transplantation.

Supply and Demand of Domestic Corneal Tissue and Its Implications on Export Potential-Using Australia as an Example.

PURPOSE: Corneal tissue importation is only possible if another country is able to export corneas without impacting its own domestic demand. Currently, there is little evidence to indicate whether export nations have such surplus capacity and in a position to export. To explore this concept, we examined our nation, Australia, which is reported to routinely decline donations because of its ability to meet domestic corneal transplant demand. Our research offers insights and opportunities for Australia and other nations to evaluate their domestic and international supply and allocation of corneal tissue in this space. METHOD: We collated 12 months of data on collected and noncollected donations, through participating Australian Eye Banks. The explanation of why some known donors were declined or not pursued indicated if demand was met and potential surplus-for-export levels. RESULTS: There were 7.5% (n = 11,889) of deaths in Australia that were notified to Australian Eye Banks during our reporting period. Of those, 9.3% (n = 1106/11,889) were recovered and allocated, 15.7% (n = 1863/11,889) were known but declined, and 75% (n = 8920/11,889) were not pursued. Of those that were declined, 64.3% (n = 1197/1863) were declined because of limitations with service/manpower at the eye bank, whereas 35.7% (n = 666/1863) were declined because demand was met. CONCLUSIONS: Australia did not meet demand all the time, during our data period. There were adequate quantities of potential donors to support increasing recovery for domestic allocation and provide for exportation without hindrance to Australian demand. Further examination of domestic supply and demand cycles and the export process is required before routine exportation.

Should Donors Consent to Export Their Corneas? Examination of Eye Tissue and Eye Care Sector Opinion.

PURPOSE: Corneal tissue international activity is only possible because of the willingness of export populations to donate their corneas on their death. Current predonation public education campaigns and at-the-point-of-donation consent practice generally includes consent for transplantation, research, and/or training. It is unclear whether a consent-for-export step is universally included in the consent process or, indeed, whether it should. We interviewed eye tissue and eye care professionals from around the world, who exported, imported, or did neither to understand current consent-for-export awareness and determine opinion on future practice. METHOD: During wider qualitative grounded-theory semistructured interviews with sector experts, to determine whether Australia should export, we captured sector opinion on consent-for-export. We used saturation and sentiment methods to determine opinion and χ2 correlation coefficients to examine association, using an α of P = 0.05. RESULTS: We interviewed 92 individuals, 83 of whom discussed consent-for-export. Of those, 51% (42/83) demonstrated some awareness of the practice; however, there were contradictions between interviewees from the same location. Regardless of current awareness, 57% (41/72) believed donors should be informed or consented for export. Their approval did not extend to donor-directed decisions, which would allow donors to decide which nation their donation should be sent, with 62.5% (45/72) opposing that notion. CONCLUSIONS: Our research indicates that the consent-for-export practice is not universally applied by exporting nations and that eye tissue and eye care professionals have limited awareness of the practice. Universally implementing a consent-for-export step within general consent practice would improve awareness, reduce confusion, and support donor wishes.

Conocimientos, actitudes y prácticas sobre donación y trasplante de córneas en comunidades rurales y urbanas de Honduras / Knowledge, attitudes and practices about corneal donation and transplantation in rural and urban communities in Honduras

Introducción: aproximadamente 600 personas urgen de trasplante de córnea en Honduras. La mayor dificultad para este procedimiento es que no se cuenta con banco de ojo en el país. Además, los estudios de conocimiento sobre donación y trasplante, son escasos. Objetivo: conocer las actitudes y prácticas de la población rural versus la urbana sobre la donación y trasplante de córnea, según conocimientos y factores sociodemográficos, con el fin de diseñar un plan de acción para concientizar la importancia de una conducta donante positiva para el beneficio del paciente con ceguera corneal. Metodología: estudio descriptivo realizado entre mayo y septiembre del 2019 en Comayagua, Intibucá y Francisco Morazán. Con una muestra de 350 personas por departamento, para un total de 1050 participantes mayores de 18 años y de ambos sexos. Se realizó entrevista por investigadores, bajo la escala de Likert, previamente validado. Variables agrupadas en demográficas, socio personales, laborales, conocimiento, creencias y aptitudes. Se analizaron los datos mediante razón de probabilidades y productos cruzados. Los resultados se expresaron en porcentajes, frecuencias y odd ratio. Resultados: 74.86% manifestó una actitud donante positiva, el 67.55% donaría a cualquier persona que lo necesitase, 48% conocía acerca de las características requeridas para el donante y. menos del 10% sabía qué es la córnea. Los factores negativos para la donación son la procedencia rural, la parentela y el desempleo en Intibucá y motivos religiosos en el área rural de Comayagua y población urbana de Francisco Morazán. Conclusiones: Es importante superar las limitaciones impuestas por la desinformación, para ello es necesario impulsar una cultura de donación a través de la creación de estrategias comunicativas de educación, con el fin de mejorar la salud visual y la demanda poblacional...(AU)

Amsterdam Research Initiative for Sub-surface Taphonomy and Anthropology (ARISTA) - A taphonomic research facility in the Netherlands for the study of human remains.

A taphonomic research facility for the study of human remains was recently realized in Amsterdam, the Netherlands, to systematically investigate the decomposition of the human body under known conditions. Governmental authorization was obtained to make use of the body donation program of the Amsterdam University Medical Centers, location Academic Medical Center, for this specific purpose. In contrast to the small number of comparable initiatives elsewhere, this facility specifically allows for the study of buried bodies e.g. with the use of telemetry and remote sensing. Here, we discuss the concept of body donation in the Netherlands, its role in taphonomic research, and the sequence of events that preceded the realization of this facility, which is the first of its kind in Europe. In addition to offering novel research options to the scientific community, we hope that it will also pave the way for the successful realization of similar initiatives in other locations.

An Organ for My Child: Public Appeals for Limited Resources.

The case of Jamie Fiske and subsequent public appeals for particular children by President Ronald Reagan represent classic cases in pediatric bioethics in which parents or others publicly appealed for a donor organ for a particular child. These raise questions about the appropriate boundaries for public appeals for a limited resource for a particular child and how the press and medical community should respond to such appeals. Public appeals by parents to advocate for their child to receive a limited resource above others promote rationing by morally irrelevant factors and shift the public focus from the national shortage of organs for transplant to the needs of a particular child. Yet these appeals are understandable and will likely continue. Recognizing this, we consider appropriate responses by the media, transplant community, hospitals, and individual clinicians.

Public Appeals Challenging Criteria for Pediatric Organ Transplantation.

In this article, I review the ethical issues that arise in the allocation of deceased-donor organs to children and young adults. By analyzing the public media cases of Sarah Murnaghan, Amelia Rivera, and Riley Hancey, I assess whether public appeals to challenge inclusion and exclusion criteria for organ transplantation are ethical and under which circumstances. The issues of pediatric allocation with limited evidence and candidacy affected by factors such as intellectual disability and marijuana use are specifically discussed. Finally, I suggest that ethical public advocacy can coexist with well-evidenced transplant allocation if and when certain conditions (morally defensible criteria, expert evidence, nonprioritization of the poster child, and greater advocacy for organ transplantation in general) are met.

Directed sibling donor cord blood donation in the Chilean Public Health System. / Donación dirigida de sangre de Cordón Umbilical de Hermano Compatible en el Sistema de Salud Público de Chile.

INTRODUCTION: Cord blood (CB) as a source of Hematopoietic Stem Cells for Transplantation (HSCT) is well established. Worldwide, nonetheless, less than 10% of the CB HSCTs are performed with a match sibling donor. Since 2004, the Chilean National Childhood Cancer Program (PINDA) net work, has established a CB directed donation program for HSCT. PATIENTS AND METHOD: An obser vational, descriptive and retrospective study was designed to assess the number and characteristics of the CB units collected in the program as well as the number, clinical characteristics and follow-up of the patients who received an HSCT from those CB units between January 2004 and October 2018. RESULTS: Sixty CB units have been collected; 55 of them with full records and stored. The median volume collected was 74.8 ml (30.0-170.8), the median number of total nucleated cells was 7.6 x 10e8 (2.0-21.1), and the median of CD34+ cells was 1.6 x 10e6 (0.2-11.6). Four high-risk leukemia patients received HSCT, all of them developed severe complications after transplantation and one patient died due to relapse. Those patients currently alive have a 100% Karnofsky/Lansky score. The median follow-up time was 8 years. CONCLUSION: The PINDA program has allowed 4 patients to be transplan ted who otherwise would not have had access to a donor. This directed donation program could be seen as a model for the development of a public cord blood bank in Chile.
