Pass the tissue: restoring researcher access to legal human donations.

The sensitivity of human tissue and previous instances of misuse have, rightfully, led to the introduction of far-reaching oversight and regulatory mechanisms for accessing, storing and sharing samples. However, these restrictions, in tandem with more broad-based privacy regulations, have had the unintended consequence of obstructing legitimate requests for medical materials. This is of real detriment to ambitions for biomedical research, most notably the precision medicine agenda. As such, this paper makes the case for facilitating authorised researcher access to human tissue and associated data along practical medical ethics lines, detailing how liberating samples from unfit regulations, re-evaluating biobanks, diversifying considerations for donor benefit-risk, future proofing donor consent and flattening hierarchies of donation acceptability equate to a more cohesive and respectful means of managing biological samples and information than is achieved at present.

Organ donation after extracorporeal cardiopulmonary resuscitation: a nationwide retrospective cohort study.

BACKGROUND: Limited data are available on organ donation practices and recipient outcomes, particularly when comparing donors who experienced cardiac arrest and received extracorporeal cardiopulmonary resuscitation (ECPR) followed by veno-arterial extracorporeal membrane oxygenation (ECMO) decannulation, versus those who experienced cardiac arrest without receiving ECPR. This study aims to explore organ donation practices and outcomes post-ECPR to enhance our understanding of the donation potential after cardiac arrest. METHODS: We conducted a nationwide retrospective cohort study using data from the Japan Organ Transplant Network database, covering all deceased organ donors between July 17, 2010, and August 31, 2022. We included donors who experienced at least one episode of cardiac arrest. During the study period, patients undergoing ECMO treatment were not eligible for a legal diagnosis of brain death. We compared the timeframes associated with each donor's management and the long-term graft outcomes of recipients between ECPR and non-ECPR groups. RESULTS: Among 370 brain death donors with an episode of cardiac arrest, 26 (7.0%) received ECPR and 344 (93.0%) did not; the majority were due to out-of-hospital cardiac arrests. The median duration of veno-arterial ECMO support after ECPR was 3 days. Patients in the ECPR group had significantly longer intervals from admission to organ procurement compared to those not receiving ECPR (13 vs. 9 days, P = 0.005). Lung graft survival rates were significantly lower in the ECPR group (log-rank test P = 0.009), with no significant differences in other organ graft survival rates. Of 160 circulatory death donors with an episode of cardiac arrest, 27 (16.9%) received ECPR and 133 (83.1%) did not. Time intervals from admission to organ procurement following circulatory death and graft survival showed no significant differences between ECPR and non-ECPR groups. The number of organs donated was similar between the ECPR and non-ECPR groups, regardless of brain or circulatory death. CONCLUSIONS: This nationwide study reveals that lung graft survival was lower in recipients from ECPR-treated donors, highlighting the need for targeted research and protocol adjustments in post-ECPR organ donation.

Unjust organ markets and why it is irrelevant that selling a kidney is the best option.

An important argument against prohibiting organ sales is that it removes the best option available to individuals in dire circumstances. However, this line of reasoning fails to recognise that selling a kidney on a regulated market is only the best option in a very narrow comparison, where a regulated organ market is compared with banning organ sales. Once we acknowledge this narrowness, selling a kidney is not the best option. This paves the way for a distributive justice-based critique of the 'best option' argument for organ markets, which illuminates that organ markets should be compared with a broader set of alternatives. If providing the option of selling a kidney is not the best option, but rather the best option we are willing to provide, and one which means that many people will remain in poverty and unjust circumstances, then this reflects poorly on those societies willing to offer only this option and not a better one.

Critical pathway for deceased donors: An analysis in three regions of Colombia / Ruta crítica de donantes fallecidos: un análisis de tres regiones en Colombia

Introduction. The critical pathway for deceased donation offers a methodical framework for guiding the donation process. It not only serves to assess performance but also to identify areas of potential improvement. Therefore, the identification and selection of potential organ donors (POD) is a key process. This study aims to describe the critical pathway for deceased donation in a cohort of POD in three regions (CRT1, CRT2, and CRT5) of Colombia. Methods. We retrospectively reviewed data of POD assessed from January 2022 to December 2022. General characteristics of POD, diagnosis, contraindication causes, and organ procurement were described. Analysis was conducted using the Chi-squared test for categorical variables and the Mann-Whitney test for quantitative variables. Results. Within the cohort of 1451 assessed POD, 441 (30.3%) were diagnosed with brain death. Among potential donors after brain death, 198 (44.9%) were eligible donors (medically suitable). Of these, 157 donors (79.3%) became actual donors (undergoing operative incision for organ recovery), with 147 (93,6 %) having at least one organ recovered (actual donors with organ recovery). Ultimately, 411 utilized organs were utilized. Additionally, there were observed differences in the characteristics of donors from different regions. Conclusion. This study reports the critical pathway for deceased donation in a cohort of POD in three regions of Colombia. This provides useful information and helps to gain insight and understanding into the process of organ donation and organ procurement in order to take actions that could improve the donation rates.

La selección de posibles donantes de órganos (PDO) es un proceso clave. El objetivo de este estudio fue describir la ruta crítica para la donación de fallecidos en una cohorte de PDO en tres regiones de Colombia. Métodos. Estudio retrospectivo de PDO evaluados durante 2022. Se describieron las características generales de los PDO, el diagnóstico y las causas de contraindicación. El análisis se llevó a cabo utilizando la prueba de Chi-cuadrado para las variables categóricas y la prueba de Mann-Whitney para las variables cuantitativas. Resultados. Entre los 1451 POD evaluados, 441 (30,3 %) fueron diagnosticados con muerte cerebral. De los posibles donantes después de la muerte cerebral, 198 (44,9 %) fueron donantes elegibles (adecuados desde el punto de vista médico). Entre ellos, 157 donantes (79,3 %) fueron donantes reales (en quienes se realizó una incisión operatoria con la intención de recuperar órganos) y 147 (93,6 %) tuvieron al menos un órgano recuperado (donantes reales con recuperación de órganos). Finalmente, se identificaron 411 órganos utilizados. Conclusión. Este estudio reporta la ruta crítica para la donación de fallecidos en una cohorte de POD en tres regiones de Colombia. Esto proporciona información útil, ayuda a obtener conocimientos y comprender el proceso de donación y obtención de órganos, para tomar medidas que puedan mejorar las tasas de donación.

The right to know from the opt-out effectiveness system perspective in organ transplantation cases.

OBJECTIVE: Aim: This article examines the legal challenges associated with opt-out and opt-in systems in transplantation cases. It focuses on the low public knowledge and awareness of the national transplantation system, assessing its compliance with international prerequisites for an opt-out system. The analysis centres on the "right to know" perspective and the effectiveness of opt-out in organ transplantation. . PATIENTS AND METHODS: Materials and Methods: The research methodology includes scientific principles, public surveys, relevant regulations from the Republic of Latvia and EU, and grey literature on the health system and organ donation in the EU. Scientific articles from databases such as Scopus and WOS were selected based on criteria such as language (English and Latvian) and focus on living wills and comparisons of organ donation systems. Previous EU and national studies, reports, and court judgments were used to analyse data on opt-in and opt-out transplantation systems and policy efficiency in organ transplantation. CONCLUSION: Conclusions: Individuals' right to autonomy over their bodies extends even after death, encompassing the right to integrity. Organ donation, being a deeply personal choice reflecting one's values and beliefs, plays a crucial role in saving lives through transplantation. To enhance cooperation and donation rates, international regulations stress the significance of public awareness regarding organ and tissue transplantation. Unfortunately, inadequate compliance by authorities and low awareness pose ethical and legal dilemmas, potentially violating constitutional rights. Reports highlight limited public understanding of transplantation systems, raising concerns, particularly in opt-out systems. National governments bear the responsibility of safeguarding these rights and addressing challenges beyond legal means, thus establishing a more ethical organ donation system that upholds voluntariness, generosity, and individual autonomy.

High-Functioning Deceased Donor Kidney Transplant System Characteristics: The British Columbia Experience With an Opt-In System.

Rationale & Objective: A high level of cooperation between organ procurement organizations and transplant programs may help maximize use of deceased donor kidneys. The practices that are essential for a high functioning organ donation and transplant system remain uncertain. We sought to report metrics of organ donation and transplant performance in British Columbia, Canada, and to assess the association of specific policies and practices that contribute to the system's performance. Study Design: A retrospective observational study. Setting & Participants: Referred deceased organ donors in British Columbia were used in the study from January 1, 2016, to December 31 2019. Exposures: Provincial, organ procurement organization, and center level policies were implemented to improve donor referral and organ utilization. Outcomes: Assessment of donor and kidney utilization along steps of the critical pathway for organ donation. Analytical Approach: Deceased donors were classified according to the critical pathway for organ donation and key donation and transplant metrics were identified. Results: There were 1,948 possible donors referred. Of 1,948, 754 (39%) were potential donors. Of 754 potential donors, 587 (78%) were consented donors. Of 587 consented donors, 480 (82%) were eligible kidney donors. Of 480 eligible kidney donors, 438 (91%) were actual kidney donors. And of 438 actual kidney donors, 432 (99%) were utilized kidney donors. One-year all-cause allograft survival was 95%. Practices implemented to improve the system's performance included hospital donor coordinators, early communication between the organ procurement organization and transplant nephrologists, dedicated organ recovery and implant surgeons, aged-based kidney allocation, and hospital admission of recipients before kidney recovery. Limitations: Assignment of causality between individual policies and practices and organ donation and utilization is limited in this observational study. Conclusions: In British Columbia, consent for donation, utilization of donated kidneys, and transplant survival are exceptionally high, suggesting the importance of an integrated deceased donor and kidney transplant service.

Optimization of all possible opportunities for deceased donor kidney donation and transplantation is essential to meet the need for transplantation. We examined the performance of organ procurement and transplant in a deceased organ donor system in British Columbia, Canada, and reviewed policies and practices that may contribute to the system's performance. We found a high level of donation, transplantation, and survival of donated kidneys and identified policies and practices that likely contribute to the system's performance.

Left lobe living donor liver transplantation using the resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID) procedure in cirrhotic patients: First case report in Korea.

In liver transplantation, the primary concern is to ensure an adequate future liver remnant (FLR) volume for the donor, while selecting a graft of sufficient size for the recipient. The living donor-resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (LD-RAPID) procedure offers a potential solution to expand the donor pool for living donor liver transplantation (LDLT). We report the first case involving a cirrhotic patient with autoimmune hepatitis and hepatocellular carcinoma, who underwent left lobe LDLT using the LD-RAPID procedure. The living liver donor (LLD) underwent a laparoscopic left hepatectomy, including middle hepatic vein. The resection on the recipient side was an extended left hepatectomy, including the middle hepatic vein orifice and caudate lobe. At postoperative day 7, a computed tomography scan showed hypertrophy of the left graft from 320 g to 465 mL (i.e., a 45.3% increase in graft volume body weight ratio from 0.60% to 0.77%). After a 7-day interval, the diseased right lobe was removed in the second stage surgery. The LD-RAPID procedure using left lobe graft allows for the use of a small liver graft or small FLR volume in LLD in LDLT, which expands the donor pool to minimize the risk to LLD by enabling the donation of a smaller liver portion.

Understanding the dynamics of deceased organ donation and utilization in Colombia.

Objective: To obtain a comprehensive overview of organ donation, organ utilization, and discard in the entire donation process in Colombia. Methods: A retrospective study of 1 451 possible donors, distributed in three regions of Colombia, evaluated in 2022. The general characteristics, diagnosis, and causes of contraindication for potential donors were described. Results: Among the 1 451 possible donors, 441 (30.4%) fulfilled brain death criteria, constituting the potential donor pool. Families consented to organ donation in 141 medically suitable cases, while 60 instances utilized legal presumption, leading to 201 eligible donors (13.9%). Of those, 160 (11.0%) were actual donors (in whom operative incision was made with the intent of organ recovery or who had at least one organ recovered). Finally, we identified 147 utilized donors (10.1%) (from whom at least one organ was transplanted). Statistically significant differences were found between age, sex, diagnosis of brain death, and donor critical pathway between regions. A total of 411 organs were transplanted from 147 utilized donors, with kidneys being the most frequently procured and transplanted organs, accounting for 280 (68.1%) of the total. This was followed by 85 livers (20.7%), 31 hearts (7.5%), 14 lungs (3.4%), and 1 pancreas (0.2%). The discard rate of procured deceased donors was 8.1%. Conclusions: About one-tenth of donors are effectively used for transplantation purposes. Our findings highlight areas of success and challenges, providing a basis for future improvements in Colombia.

Single center utilization and post-transplant outcomes of thoracoabdominal normothermic regional perfusion deceased cardiac donor organs.

INTRODUCTION: Thoracoabdominal normothermic regional perfusion (TA-NRP) following cardiac death is an emerging multivisceral organ procurement technique. Recent national studies on outcomes of presumptive TA-NRP-procured organs are limited by potential misclassification since TA-NRP is not differentiated from donation after cardiac death (DCD) in registry data. METHODS: We studied 22 donors whose designees consented to TA-NRP and organ procurement performed at our institution between January 20, 2020 and July 3, 2022. We identified these donors in SRTR to describe organ utilization and recipient outcomes and compared them to recipients of traditional DCD (tDCD) and donation after brain death (DBD) organs during the same timeframe. RESULTS: All 22 donors progressed to cardiac arrest and underwent TA-NRP followed by heart, lung, kidney, and/or liver procurement. Median donor age was 41 years, 55% had anoxic brain injury, 45% were hypertensive, 0% were diabetic, and median kidney donor profile index was 40%. TA-NRP utilization was high across all organ types (88%-100%), with a higher percentage of kidneys procured via TA-NRP compared to tDCD (88% vs. 72%, p = .02). Recipient and graft survival ranged from 89% to 100% and were comparable to tDCD and DBD recipients (p ≥ .2). Delayed graft function was lower for kidneys procured from TA-NRP compared to tDCD donors (27% vs. 44%, p = .045). CONCLUSION: Procurement from TA-NRP donors yielded high organ utilization, with outcomes comparable to tDCD and DBD recipients across organ types. Further large-scale study of TA-NRP donors, facilitated by its capture in the national registry, will be critical to fully understand its impact as an organ procurement technique.

Is it ethically permissible for GPs to promote non-directed altruistic kidney donation to healthy adults?

Doctors hold coexisting ethical duties to avoid causing deliberate harm to their patients (non-maleficence), to act in patients' best interests (beneficence), to respect patients' right to self-determination (autonomy) and to ensure that costs and benefits are fairly distributed among patients (justice). In the context of non-directed altruistic kidney donations (NDAKD), doctors' duties of autonomy and justice are in tension with those of non-maleficence and beneficence. This article examines these competing duties across three scenarios in which general practitioners (GPs) could promote NDAKD to healthy adults. In the first-when a healthy adult patient prompts the GP to discuss NDAKD-the GP is ethically obligated to counsel the patient about NDAKD to respect their autonomy, yet this does not constitute any form of promotion of NDAKD. In the remaining scenarios, healthy adult patients are unaware of the possibility of NDAKD. In the second, it is ethically permissible for GPs to indirectly raise awareness of NDAKD among healthy adults by displaying recruitment campaign material to non-specified groups of patients in their waiting rooms. In the third, it is ethically impermissible for GPs to directly promote NDAKD to individual healthy adults by raising the possibility of NDAKD with such individuals. The major counterarguments raised against this position are problems with kinds of counselling that fail to reach expected professional standards, rather than problems with the ethical claims made in this article.

Global legislation regulating the donation, procurement and distribution processes of organs and tissues from deceased donors for transplants: A scoping review.

Introduction: Organ transplantation is one of the most successful advances in modern medicine. However, a legal system is necessary for its practice to be free from ethical flaws and to respect donors, recipients, and family members. Objective: To map the global legislation regulating the donation, capture and distribution processes of organs and tissues from deceased donors for transplants. Method: A scoping review according to the Joanna Briggs Institute was conducted in the following databases: Medline, CINAHL, Virtual Health Library, SCOPUS, Web of Science, Science Direct, and EMBASE, as well as gray literature, and reported according to the PRISMA extension for scoping reviews. Results: We identified 3302 records, of which 77 were analyzed which enabled mapping the type of consent adopted and the existence of current legislation for harvesting organs and tissues after circulatory and brain death. Conclusion: Opt-out consent predominates in Europe, and there is harvesting after brain and circulatory death. Opt-out predominates in the Americas, while Opt-in and harvesting of organs and tissues after brain death predominate in Asia and Oceania. The procurement of organs and tissues from deceased donors is practically non-existent in Africa.

What do we know about eligible organ donors? Analysis of data from a local Registry.

BACKGROUND: The imbalance between supply and demand for organ donations remains a hot topic for international debate. Brain-dead organ donors (DBDs) constitute the majority of organ donations in Poland. OBJECTIVES: To identify the factors that guided intensivists in qualifying a brain-dead patient as a potential organ donor, and whether the factors that significantly influenced the decision to qualify constituted an actual contraindication. MATERIAL AND METHODS: We performed a retrospective study based on data from the Silesian ICU Registry from 2010-2020 and publicly available information from Poltransplant. We compared the demographic and clinical characteristics of patients diagnosed with brain death who were identified as eligible and ineligible organ donors. RESULTS: Out of 25,465 patients enrolled in the Silesian ICU Registry, brain death was diagnosed in 385 (1.51%) study participants, and 61 of the records were excluded due to data incompleteness. In the remaining group (n = 324), there were 201 men and 123 women. Of them, only 180 study participants were reported as eligible donors (55.5%). Six patients had absolute contraindications to organ donation. CONCLUSIONS: A relatively small number of patients diagnosed with brain death were qualified by intensivists as eligible organ donors, with a limited number of medical factors influencing this decision. This means that other non-medical factors may affect the qualification of DBDs for organ procurement.

Exploring current physiotherapy practices in the care of people who are potential lung donors: A qualitative study.

OBJECTIVE: The aim of this study was to determine physiotherapists' current practices and perspectives regarding their role in caring for people who are potential lung donors in the intensive care unit (ICU). METHODS: A qualitative descriptive design was used. Qualitative data were collected through audio-recorded, semistructured focus groups with a purposive sample of physiotherapists with experience working with people who are potential lung donors in ICUs. Two investigators completed independent thematic analysis to identify themes. RESULTS: Seven focus groups were completed with 27 physiotherapists at six metropolitan health services in Victoria, Australia. Six key themes were identified: (i) physiotherapists' involvement in care was highly variable; (ii) physiotherapists were not aware of existing evidence or guidelines for the care of people who are potential donors and followed usual practices; (iii) a consistent vision of the physiotherapy role was lacking; (iv) physiotherapists' engagement with the team routinely involved in care of people who are potential donors varied considerably; (v) physiotherapists faced practice challenges associated with delivering care to potential donors; and (vi) several enablers could support a role for physiotherapy in this patient population. CONCLUSIONS: Variability in physiotherapy practice is associated with local ICU culture, physiotherapy leadership capabilities, knowledge, and experience. The spectrum of practice ranged from physiotherapists being highly engaged to being completely uninvolved. Physiotherapists held mixed perspectives regarding whether physiotherapists should have a role in managing people who are potential lung donors. It would benefit the profession to develop consensus and standardisation of the role of physiotherapists in caring for these patients. TWEETABLE ABSTRACT: Variability in views and practices amongst physiotherapists who provide care to patients who are potential lung donors in the ICU.

Estudio retrospectivo de 1 451 donantes posibles, distribuidos en tres regiones de Colombia, que fueron evaluados en el 2022. Se describen las características generales, el diagnóstico y las causas de contraindicación de los donantes potenciales. Resultados. De los 1 451 donantes posibles, 441 (30,4%) cumplían con los criterios de muerte encefálica y constituyeron el conjunto de donantes potenciales. Las familias consintieron la donación de órganos en 141 casos aptos desde el punto de vista médico, mientras que en 60 casos se recurrió a la presunción legal, con lo que se llegó a 201 donantes aptos (13,9%). De estos, 160 (11,0%) fueron donantes reales (en los que se les practicó una incisión quirúrgica para la extracción de órganos o se obtuvo al menos un órgano). En última instancia, hubo 147 donantes utilizados (10,1%) (de los que se trasplantó al menos un órgano). Se observaron diferencias estadísticamente significativas entre las regiones en cuanto a edad, sexo, diagnóstico de muerte encefálica y vía crítica del donante. Se trasplantaron un total de 411 órganos procedentes de 147 donantes utilizados; los riñones fueron los órganos obtenidos y trasplantados con mayor frecuencia, ya que supusieron 280 (68,1%) del total de órganos, seguidos del hígado (85, 20,7%), el corazón (31 , 7,5%), los pulmones (14, 3,4%) y el páncreas (1, 0,2%). La tasa de descarte de los donantes fallecidos disponibles fue del 8,1%. Conclusiones. Aproximadamente una décima parte de los donantes son utilizados, de hecho, para realizar trasplantes. Estos datos destacan las áreas en las que se han obtenido buenos resultados y aquellas en las que se presentan desafíos, lo cual proporciona una base para futuras mejoras en Colombia.

RESUMO Objetivo. Obter uma visão geral e abrangente da doação, do aproveitamento e do descarte de órgãos em todo o processo de doação na Colômbia. Métodos. Estudo retrospectivo de 1 451 possíveis doadores em três regiões da Colômbia que foram avaliados em 2022. Foram descritas as características gerais, o diagnóstico e os motivos para a contraindicação de potenciais doadores. Resultados. Dentre os 1 451 possíveis doadores, 441 (30,4%) preencheram os critérios de morte encefálica, formando o grupo de potenciais doadores. Em 141 casos considerados clinicamente aptos, as famílias consentiram com a doação de órgãos, e em 60 casos utilizou-se o princípio da presunção legal, resultando em 201 doadores elegíveis (13,9%). Desses, 160 (11,0%) foram doadores efetivos (ou seja, doadores nos quais foi feita uma incisão cirúrgica com a intenção de remover um órgão ou pessoas com pelo menos um órgão removido). Por fim, foram identificados 147 doadores utilizados (10,1%) (ou seja, que doaram pelo menos um órgão que foi transplantado). Foram encontradas diferenças estatisticamente significantes entre idade, sexo, diagnóstico de morte encefálica e itinerário crítico de doação entre as regiões. Um total de 411 órgãos foram transplantados de 147 doadores utilizados. Os rins foram os órgãos mais frequentemente removidos e transplantados, representando 280 (68,1%) do total, seguido de 85 fígados (20,7%), 31 corações (7,5%), 14 pulmões (3,4%) e 1 pâncreas (0,2%). A taxa de descarte de doadores falecidos com órgãos removidos foi de 8,1%. Conclusões. Cerca de um décimo dos doadores são efetivamente usados para fins de transplante. Nossos achados destacam áreas de sucesso e desafios, oferecendo uma base para futuras melhorias na Colômbia.

Abstract Objective To analyze family refusals to donate a cornea for transplantation in an Organ Procurement Organization. Methods This was a quantitative cross-sectional study on corneal donation refusals from potential brain-dead donors. The data source was based on the Terms of Authorization for Donation of Organs and Tissues signed from January 2001 to December 2020 in an Organ Procurement Organization. Data were collected, tabulated, and analyzed in a descriptive and inferential manner. The present study was approved by the Research Ethics Committee. Results Of the 2,447 Terms of Authorization for Donation of Organs and Tissues signed in the above period, 620 (25.34%) of them refused to donate a cornea. Regarding the time trend of corneal donation refusals, the period 2001-2009 was the only one that showed significance, when the 0-11 and 12-19 age groups showed a decreasing trend and that of 60 years or older showed an increasing trend. In the period 2001-2020, the age groups of 20-40, 41-59, and 60 years or older had lower rates of refusal to donate a cornea (48%, 59%, and 73%, respectively). Conclusion The age group is associated with refusal because older individuals had the highest refusal rates.

Research involving the recently deceased: ethics questions that must be answered.

Research involving recently deceased humans that are physiologically maintained following declaration of death by neurologic criteria-or 'research involving the recently deceased'-can fill a translational research gap while reducing harm to animals and living human subjects. It also creates new challenges for honouring the donor's legacy, respecting the rights of donor loved ones, resource allocation and public health. As this research model gains traction, new empirical ethics questions must be answered to preserve public trust in all forms of tissue donation and in the practice of medicine while respecting the legacy of the deceased and the rights of donor loved ones. This article suggests several topics for immediate investigation to understand the attitudes and experiences of researchers, clinical collaborators, donor loved ones and the public to ensure research involving the recently deceased advances ethically.

Caracterização epidemiológica e causas da não doação por potenciais doadores de órgãos em morte encefálica / Epidemiological characterization and causes of non-donation by potential brain-dead organ donors / Caracterización epidemiológica y causas de la no donación de potenciales donantes de órganos en muerte cerebral

Objetivo: analisar as características epidemiológicas e causas da não efetivação do processo de doação de órgãos e tecidos de potenciais doadores em morte encefálica. Método: estudo transversal, com dados secundários do ano de 2019, obtidos de formulários de notificação de morte encefálica de pacientes com idade igual e superior a 18 anos, analisados descritiva e inferencialmente, após aprovação pelo comitê de ética. Resultados: notificadas 231 mortes encefálicas, com maior incidência de pessoas do sexo masculino, idade média de 48 anos e notificações dos hospitais públicos. Em Campo Grande, Mato grosso do Sul, observou-se maior número de notificações e o menor tempo entre a notificação e o primeiro exame clínico (RR: 4,01; IC 2,17-7,41; p<0,001). Entre os casos de não doação, 75,8% ocorreram por contraindicação médica e recusa familiar. Conclusão: houve predomínio de adultos jovens, não doadores de órgãos, cuja negativa da família deu-se pela vontade de manter o corpo íntegro.(AU)

Objective: to analyze the epidemiological characteristics and causes of non-completion of the organ and tissue donation process from potential brain-dead donors. Method: cross-sectional study, with secondary data from 2019, obtained from brain death notification forms of patients aged 18 years and over, analyzed descriptively and inferentially, after approval by the ethics committee. Results: 231 brain deaths were reported, with a higher incidence of males, average age of 48 years and notifications from public hospitals. In Campo Grande, Mato grosso do Sul, Brazil, there was a greater number of notifications and a shorter time between notification and the first clinical examination (RR: 4.01; CI 2.17-7.41; p<0.001). Among cases of non-donation, 75.8% occurred due to medical contraindication and family refusal. Conclusion: there was a predominance of young adults, non-organ donors, whose family's refusal was due to the desire to keep the body intact(AU)

Update on the ethical, legal and technical challenges of translating xenotransplantation.

This manuscript reports on a landmark symposium on the ethical, legal and technical challenges of xenotransplantation in the UK. King's College London, with endorsement from the British Transplantation Society (BTS), and the European Society of Organ Transplantation (ESOT), brought together a group of experts in xenotransplantation science, ethics and law to discuss the ethical, regulatory and technical challenges surrounding translating xenotransplantation into the clinical setting. The symposium was the first of its kind in the UK for 20 years. This paper summarises the content of the expert lectures showcasing the progress which has been made in xenotransplantation including-the history of xenotransplantation, advances in gene edited animals and progress towards clinical xenotransplantation. We then set out the ethical and legal issues still to be resolved. Finally, we report the themes of the roundtable discussion highlighting areas of consensus and controversy. While the detail of the legal discussion was directed towards the UK, the principles and summary reported here are intended to be applicable to any jurisdiction seeking to implement clinical xenotransplantation.

[Transculturation and validation of a Questionnaire Factors Influencing Organ Donation]. / Transculturación y validación del cuestionario Factores que influyen en la Donación de Órganos.

Background: There are validated questionnaires in Spanish that evaluate the factors that influence organ donation, but they are not designed for the open population or do not delve into various aspects such as the one proposed. Objective: Validate an instrument to evaluate the factors that influence organ donation in Mexico. Material and methods: Phase 1: Development of the instrument. Translation into Spanish of the questionnaire "Factors Inffluencing Organ Donation in Qatar", adapted by experts in donation and clinimetry. Simultaneously, the definitive version of the questionnaire "Factors that Influence Organ Donation" (FIDO) and the questionnaire "International Donor Collaborative Project" were applied to patients, relatives and staff of a tertiary hospital in Puebla, Mexico. Mind a week after 200 respondents. Cronbach's Alpha (AC) (internal consistency), Intraclass Correlation Coefficient (ICC) (external consistency), and Phi (Phi) and Chi square Coefficient (concurrent validity in intention to donate) were obtained. Results: AC and ICC by domain: Knowledge 0.625 and 0.372; Attitudes 0.776 and 0.761; Beliefs 0.649 and 0.633; Intentions 0.126 and 0.123; Phi: 0.976, Chi square: 2.358 (p = 0.125). Conclusions: The FIDO questionnaire is valid and consistent to assess knowledge, attitudes, beliefs and intentions in organ donation in the general Mexican population.

Introducción: existen cuestionarios validados en español que evalúan los factores que influyen en la donación de órganos, pero no están diseñados para población abierta o no exploran aspectos diversos como el propuesto. Objetivo: validar un instrumento para evaluar los factores que influyen en la donación de órganos en México. Material y métodos: fase 1: Elaboración del instrumento. Traducción al español del cuestionario Factors Influencing Organ Donation in Qatar, adaptado por expertos en donación y clinimetría. Se realizaron pruebas piloto hasta lograr acuerdo en dos rondas consecutivas. Fase 2: Validez y consistencia. Simultáneamente se aplicó la versión definitiva del cuestionario Factores que Influyen en la Donación de Órganos (FIDO) y el cuestionario Proyecto Colaborativo Internacional Donante a pacientes, familiares y personal de un hospital de tercer nivel de Puebla, México. Se reaplicó telefónicamente una semana después a 200 respondientes. Se utilizó alfa de Cronbach (AC) (consistencia interna), coeficiente de correlación intraclase (CCI) (consistencia externa), y coeficiente de Phi (Phi) y Chi cuadrada (validez concurrente en intención de donar). Resultados: AC y CCI por dominio: Conocimiento 0.625 y 0.372; Actitudes 0.776 y 0.761; Creencias 0.649 y 0.633; Intenciones 0.126 y 0.123; Global 0.774 y 0.675, respectivamente (p = 0.000); Phi: 0.976, Chi cuadrada: 2.358 (p = 0.125). Conclusiones: el cuestionario FIDO es válido y consistente para explorar: conocimiento, actitudes, creencias e intenciones en donación de órganos en población general mexicana.
