Combined en bloc heart and liver organ procurement.

A combined heart+liver transplant is the only option for survival in some patients with end-stage combined cardiac and hepatic disease. These patients may suffer from congenital or acquired cardiac disease. The potential aetiologies of the associated hepatic disease are heterogeneous and include systemic disease that impacts the liver as well as venous congestion in patients with functionally univentricular circulation. In the latter scenario, patients with functionally univentricular circulation often require complex cardiac reconstruction in the setting of a cardiac transplant after staged palliation. During cardiac procurement, our approach is to dissect the entire ascending aorta and aortic arch in continuity; the entire superior caval vein and innominate vein in continuity; and the pulmonary arteries from hilum to hilum if the donor is not a candidate for recovery of the lungs. The cardiac and abdominal organ procurement teams work in parallel during dissection and combined en bloc cardio-hepatectomy. This technique minimizes exposure of both organs to cold ischaemia. This video tutorial demonstrates the key steps for combined en bloc heart+liver organ procurement.

Challenges and Possible Solutions to Donation After Circulatory Death in Turkey and the Middle East: Panel Discussion Summary Report.

The 20th century has witnessed the development of tissue and organ transplantation as the best therapeutic option for end-stage organ failure; however, organ shortages remain a prominent worldwide issue. Donation after circulatory death is an accepted practice in several countries around the world but also poses many challenges. Presently, controlled donations after circulatory death are not really in practice in Turkey and the Middle East, and the implementation of this practice seems complicated. To gather information about the possible reasons underlying the lack of organs from donors after circulatory death, as well as solutions, a discussion session took place during the International Symposium on "Brain Death and Circulatory Death" on November 29-30, 2023, in Ankara, Turkey. A description on different topics that were discussed is presented.

The Effects of 15 Golden Key Points to Increase the Family Consent Rate in Iran.

OBJECTIVES: In nations where organ donation is governed by the opt-in policy, the most crucial stage in the organ procurement process is the family approach and gaining the approval of families of decedents with brain death. In times of grief and sorrow, the ability of health care workers to communicate and have donation conversations is vital to the decision-making process of families and the subsequent consent rate. In this study, we investigated the effects of teaching important points to coordinators in the family approach and gaining consent of families for organ donation. MATERIALS AND METHODS: A new training program for Iranian coordinators was designed to increase the skills and knowledge of interviewers and increase the self-confidence of the coordinators. In the training program, 15 golden key points to have when meeting with families of brain dead decedents regarding organ donation consent were presented and discussed with participants. Three coordinating groups participated in this training program. The satisfaction rate of the families was assessed at comparable intervals (12 months for group 1, 6 months for group 2, and 3 months for group 3) before and after the training session to assess the continuity of the training impact. We used the Wilcoxon signed rank test for comparisons. RESULTS: The family consent rate was significantly different for all participants, before and after the 15 golden key points were presented, increasing from 50% to 62.5% (P = .037). In addition, participant sex (P = .051), previous training (P = .090), education (P = .068), and cooperation time (P = .008) had significant effects on family consent rate. CONCLUSIONS: Our training approach can increase the performance of coordinators in achieving family satisfaction.

Cardiac organoids do not warrant additional moral scrutiny.

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.

Moving Boundaries for Improving Organ Transplant Availability.

This brief overview is designed to address the options for increasing organ transplant rates to between 100 and 120 transplanted organs per million population globally. The focus of this review is the data produced through the World Health Organization's Global Observatory on Donation and Transplantation, with consideration for the issues that different countries need to address to achieve higher transplant rates. Without both optimized living donation and optimized deceased donation, rates of transplant are not sufficient to provide for a level of self-dependency for transplant therapy. Deceased donation comprises both donation from donors declared dead after cessation of all functions of the brain and donors declared dead from irreversible cessation of circulation of the blood. The preservation strategies that hold the greatest chance of increasing the utility of marginal and older donors involve normothermic circulation to prevent ischemic damage and potentially restore function of damaged organs. Normothermic in situ perfusion of abdominal organs has demonstrated utility, and consideration must be given to normothermic perfusion of the thoracic organs to improve heart and lung transplants, but this may challenge the legal definitions of death. Each nation must endeavor to increase organ donation capacity across the spectrum of donor types and must address the opportunities that normothermic perfusion of organs at retrieval may offer to alleviate shortages of organs for transplant and provide selfdependency for the communities.

Why Altruistic Organ Donations Are Not Meeting Demands.

Solid-organ transplantation remains the optimal therapeutic option for end-stage organ disease. Altruistic donation represents the ultimate sign of generosity and the most important gift of life. Currently, <10% of the global needs for transplant are fulfilled. Organ shortages result from an inability to provide an adequate organ supply to match demands. The recently observed stagnation in living kidney donations in the United States is related to a drop in all types of organ donations from living related donors, which has been paralleled with a steady and continuous increase in all living unrelated donations. Some forms of living unrelated donation represent a financially driven survival system within which wealthy recipients exploit poor donors. Low rates of altruistic donation are related to cultural barriers, religious obstacles, fear, and consequent distrust in the system. The low rate indicates a state of lack of societal solidarity, a consequence of the state of subconsciousness at the individual and collective levels that humanity is living in. Human domestication, the conditioning process that humans go through since birth and the primary facilitator of this subconscious state, is guarded through familial, social, cultural, religious, political, and mass media organizations, which are all under the influence of the monetary establishment. Acquired beliefs, mainly during the domestication process, influence our perception of the environment, our values, and ultimately our way of life. Unfortunately, this conditioning process is negatively enforced, leading to a stressful state. The powerful subconscious mind places humans in a permanent survival mode, resulting in loss of intelligence, indispensable for well-being and happiness. Altruistic donation requires a close cooperation between all parties involved in the donation process and necessitates a positive reprograming of our subconscious based on sharing, generosity, satisfaction, gratitude, trust, inner peace, and ultimately happiness, well-known constituents of unconditional love, which represents the peak of consciousness.

Donation after Brain Death and Circulatory Death in Turkey: Current Status.

Tissue and organ transplantation is the best treatment option for end-stage organ failure. However, organ shortage still remains to be the greatest challenge facing the field of organ transplantation. Millions of people die and are buried with healthy organs, which could save the lives of many patients who continue to wait on transplant lists. Countries must aim to work towards a system of matching organs as much as possible with the deceased donation to meet the growing demand for organs. This action will not only result in the reduction of organ trafficking activities but shall also make an enormous difference to those patients awaiting transplants where living organ donors are not an option. Donation after circulator death (DCD) has gained much attention over the last decade as one of the accepted practices in order to expand the donor pool. DCD donation takes place after declaration of death using cardio-respiratory criteria in contrast to donation after brain death (DBD) where neurological criteria are used. Although DCD remains a focus of interest and contributes to donor numbers in many countries, it also poses many challenges medically, ethically and legally.

Road To Deceased Donor Transplantation in Egypt.

In Egypt, there is presently a growing need to have a deceased donor transplant program. Egypt conducted its first kidney transplant from a living donor in 1976 and a first partial liver transplant in 2001. Since 2009, the Egyptian Health Authorities Combat Transplant Tourism in concordance with ethics codes and the Declaration of Istanbul Custodian Group has been in place. The Egyptian Transplantation Law of 2011 mentions that organs could be procured from deceased donors based on a will and on family consent. This law has had many critics, including religious authorities who have stressed that organs cannot be taken from a person with brain death because, in their view, life ends with death of all organs. Many intensivists disagree over the definition of death. In addition, the media has communicated contradicting and sometimes misleading health care information. Mummification is rooted in pharos practice and linked to religious beliefs. The ancient Egyptians believed that, by burying the deceased with their organs, they may rejoin with them in the afterlife. Since 2019, the transplant community in Egypt has started collaborations with international transplant organizations and campaigns with doctors and celebrities to donate their organs after death, which have stressed that a deceased donor program could help against end-stage organ mortality. In November 2022, after communications with politicians, President Abdelfattah El Sisi directed the government to establish a regional center for organ transplantation, which aimed to be the biggest in the Middle East and North Africa region. The new center will be part of a new medical city that would replace Nasser Medical Institution in Cairo, Egypt. The Ministry of Health issued an official form to be signed by a person before his death, accepting use of organs, to give hope and support to other patients in need.

Evolution of the Concept of Death.

The definition of death remains unresolved. To define death, one has to define the characteristics of a living person and to confirm whether an individual with brain death fulfils any of these characteristics. Although the concept of irreversible cessation of brain function is clear, controversy remains on the treatment of individuals with brain death and beating hearts. An individual with brain death but a beating heart is not breathing on his own and is dependent on medications and machines to maintain respiration, heartbeat, and blood pressure. Muslim scholars remain divided over the issue of whether death also means irreversible cessation of brain function. Questions remain on when it is permissible to remove vital organs for organ transplant. Groups have advocated for uniformity in law and medical practice on the definition of brain death.

Organ Donation in Syria.

The first living donor kidney transplant in Syria was performed 44 years ago; by the end of 2022, 6265 renal transplants had been performed in Syria. Kidney, bone marrow, cornea, and stem cells are the only organs or tissues that can be transplanted in Syria. Although 3 heart transplants from deceased donors were performed in the late 1980s, cardiac transplant activities have since discontinued. In 2003, national Syrian legislation was enacted authorizing the use of organs from living unrelated and deceased donors. This important law was preceded by another big stride: the acceptance by the higher Islamic religious authorities in Syria in 2001 of the principle of procurement of organs from deceased donors, provided that consent is given by a first- or second-degree relative. After the law was enacted, kidney transplant rates increased from 7 per million population in 2002 to 17 per million population in 2007. Kidney transplants performed abroad for Syrian patients declined from 25% in 2002 to <2% in 2007. Rates plateaued through 2010, before the political crisis started in 2011. Forty-four years after the first successful kidney transplant in Syria, patients needing an organ transplant rely on living donors only. Moreover, 20 years after the law authorizing use of organs from deceased donors, a program is still not in place in Syria. The war, limited resources, and lack of public awareness about the importance of organ donation and transplant appear to be factors inhibiting initiation of a deceased donor program in Syria. A concerted and ongoing education campaign is needed to increase awareness of organ donation, change negative public attitudes, and gain societal acceptance. Every effort must be made to initiate a deceased donor program to lessen the burden on living donors and to enable national self-sufficiency in organs for transplant.

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.

Lung Transplantation in Controlled Donation after Circulatory-Determination-of-Death Using Normothermic Abdominal Perfusion.

The main limitation to increased rates of lung transplantation (LT) continues to be the availability of suitable donors. At present, the largest source of lung allografts is still donation after the neurologic determination of death (brain-death donors, DBD). However, only 20% of these donors provide acceptable lung allografts for transplantation. One of the proposed strategies to increase the lung donor pool is the use of donors after circulatory-determination-of-death (DCD), which has the potential to significantly alleviate the shortage of transplantable lungs. According to the Maastricht classification, there are five types of DCD donors. The first two categories are uncontrolled DCD donors (uDCD); the other three are controlled DCD donors (cDCD). Clinical experience with uncontrolled DCD donors is scarce and remains limited to small case series. Controlled DCD donation, meanwhile, is the most accepted type of DCD donation for lungs. Although the DCD donor pool has significantly increased, it is still underutilized worldwide. To achieve a high retrieval rate, experience with DCD donation, adequate management of the potential DCD donor at the intensive care unit (ICU), and expertise in combined organ procurement are critical. This review presents a concise update of lung donation after circulatory-determination-of-death and includes a step-by-step protocol of lung procurement using abdominal normothermic regional perfusion.

Meeting the Shortage of Human Cells and Tissues: The Andalusian Quality Assurance Programme for Tissue Donation.

Background A quality assurance programme for the tissue donation process was launched in Andalusia in 2020 to facilitate the integration of tissue donation into end-of-life care, and to respond to the growing need for human tissue for therapeutic purposes. The results of this programme are presented here. Methods After identifying the hospital departments in which to intensify the detection of tissue donors, expanding training activities and designing a specific data collection system for possible tissue donors who do not donate their tissues, the results of the donation activity were quantified and the causes of non-donation were analysed by applying the critical pathway for deceased tissue donation methodology. Results After an initial drop in activity, which coincided with the coronavirus pandemic, the number of tissue donors increased by 48.4% in 2022 compared to 2019. From the eligible donors, 83% were actual tissue donors and 71% were utilised donors. The modifiable causes of tissue donation loss, in order of frequency, were family refusal, followed by organisational or logistical issues, failure to notify or failure to identify possible donors, and failure to complete donor evaluation. Conclusion As a result of the collaboration of the various professionals involved in the programme, tissue donation activity has increased remarkably, the potential and effectiveness of the donation process have been evaluated, and areas for improvement have been identified, which we hope will lead to continuous improvement of the process.

Asystolic donor warm ischemia time is associated with development of postreperfusion syndrome in donation after circulatory death liver transplant.

BACKGROUND: Individual events during donation after circulatory death (DCD) procurement, such as hypotensive or hypoxic warm ischemia, or circulatory arrest are all a part of donor warm ischemia time (dWIT), and may have differing effects on the outcome of the liver graft. This study aimed to identify risk factors for postreperfusion syndrome (PRS), a state of severe hemodynamic derangement following graft reperfusion, and its impact on DCD liver transplantation (LT) outcomes. METHODS: This was a retrospective analysis using 106 DCD LT. Detailed information for events during procurement (withdrawal of life support; systolic blood pressure < 80 mmHg; oxygen saturation < 80%; circulatory arrest; aortic cold perfusion) and their association with the development of PRS were examined using logistic regression. RESULTS: The overall incidence of PRS was 26.4%, occurring in 28 patients. Independent risk factors for PRS were asystolic dWIT (odds ratio (OR) 3.65, 95% confidence interval (CI) 1.38-9.66) and MELD score (OR 1.06, 95% CI 1.01-1.10). Total bilirubin was significantly higher in the PRS group at postoperative day (POD) 1 (p = .02; 5.2 mg/dL vs. 3.4 mg/dL), POD 3 (p = .049; 4.5 mg/dL vs. 2.8 mg/dL), and POD 7 (p = .04; 3.1 mg/dL vs. 1.9 mg/dL). Renal replacement therapy after LT was more likely to be required in the PRS group (p = .01; 48.2% vs. 23.1%). CONCLUSION: Asystolic dWIT is a risk factor for the development of PRS in DCD LT. Our results suggest that asystolic dWIT should be considered when selecting DCD liver donors.
