ABSTRACT

(1) Background: Cardiac donation after circulatory death (DCD) is an emerging paradigm in organ transplantation. However, this technique is recent and has only been implemented by highly experienced centers. This study compares the characteristics and outcomes of thoraco-abdominal normothermic regional perfusion (TANRP) and static cold-storage DCD and traditional donation after brain death (DBD) cardiac transplants (CT) in a newly stablished transplant program with restricted donor availability. (2) Method: We performed a retrospective, single-center study of all adult patients who underwent a CT between November 2019 and December 2023, with a follow-up conducted until August 2024. Data were retrieved from medical records. A review of the current literature on DCD CT was conducted to provide a broader context for our findings. The primary outcome was survival at 6 months after transplantation. (3) Results: During the study period, 76 adults (median age 56 years [IQR: 50-63 years]) underwent CT, and 12 (16%) were DCD donors. DCD donors had a similar age (46 vs. 47 years, p = 0.727), were mostly male (92%), and one patient had left ventricular dysfunction during the intraoperative DCD process. There were no significant differences in recipients' characteristics. Survival was similar in the DCD group compared to DBD at 6 months (100 vs. 94%) and 12 months post-CT survival (92% vs. 94%), p = 0.82. There was no primary graft dysfunction in the DCD group (9% in DBD, p = 0.581). The median total hospital stay was longer in the DCD group (46 vs. 21 days, p = 0.021). An increase of 150% in transplantation activity due to DCD was estimated. (4) Conclusions: In a new CT program that utilized older donors and included recipients with similar illnesses and comorbidities, comparable outcomes between DCD and DBD hearts were observed. DCD was rapidly incorporated into the transplant activity, demonstrating an expedited learning curve and significantly increasing the availability of donor hearts.

ABSTRACT

Although pediatric organ donation represents a small proportion of overall organ donation, children and adolescents make a significant contribution to the pool of donated organs. In this study 252 solid organs were collected from children and adolescent. Two hundred and two recipients benefited from 62 pediatric organ donors, with a recipient/donor ratio of 3.3.


BACKGROUND: Pediatric organ donors represent a small but important portion of the deceased donor pool, helping both children and adults in the transplant waitlist. Despite this, pediatric donation remains an overlooked subject of research. METHODS: Retrospective, single­center, descriptive study. All brain death patients under 18 years old who were admitted to the Intensive Care Unit (ICU) between January 1st, 2006, and December 31st, 2021, and who were eligible for organ donation were included. RESULTS: Between January 2006 and December 2021, 200 children/adolescent died in the ICU. From those, 62 patients (31%) were considered eligible for organ donation. The mean age of the donors at the time of death was 8.8 years. Sixty­three per cent were male. The most frequent cause of death was traumatic brain injury (n = 36). Two hundred and fifty organs were collected benefitting 202 persons with a recipient/donor ratio of 3.3. Kidneys were the most frequent organ donated (n = 116), followed by liver (n = 56) and heart (n = 34). The median number of organs donated per child was four, with a minimum of 1 organ and maximum of 8. CONCLUSIONS: Pediatric organ donation represents a small proportion of overall organ donation, but children and adolescents have important impact on the lives they save. The field of pediatric organ donation needs more research to better understand the contribution of the pediatric population to both adults and children who wait for an organ.

ABSTRACT

BACKGROUND: The demand for organ transplants, both globally and in South Korea, substantially exceeds the supply, a situation that might have been aggravated by the enactment of the Life-Sustaining Treatment Decision Act (LSTDA) in February 2018. This legislation may influence emergency medical procedures and the availability of organs from brain-dead donors. This study aimed to assess LSTDA's impact, introduced in February 2018, on organ donation status in out-of-hospital cardiac arrest (OHCA) patients in a metropolitan city and identified related factors. METHODS: We conducted a retrospective analysis of a regional cardiac arrest registry. This study included patients aged 16 or older with cardiac arrest and a cerebral performance category (CPC) score of 5 from January 2015 to December 2022. The exclusion criteria were CPC scores of 1-4, patients under 16 years, and patients declared dead or transferred from emergency departments. Logistic regression analysis was used to analyse factors affecting organ donation. RESULTS: Of the 751 patients included in this study, 47 were organ donors, with a median age of 47 years. Before the LSTDA, there were 30 organ donations, which declined to 17 after its implementation. In the organ donation group, the causes of cardiac arrest included medical (34%), hanging (46.8%), and trauma (19.2%). The adjusted odds ratio for organ donation before the LSTDA implementation was 6.12 (95% CI 3.09-12.12), with non-medical aetiology as associated factors. CONCLUSION: The enactment of the LSTDA in 2018 in South Korea may be linked to reduced organ donations among patients with OHCA, underscoring the need to re-evaluate the medical and legal aspects of organ donation, especially considering end-of-life care decisions.

ABSTRACT

INTRODUCTION: The apnea test (AT) is a crucial procedure in determining brain death (BD), with detection of spontaneous breathing efforts serving as a key criterion. Numerous national statutes mandate complete disconnection of the patient from the ventilator during the procedure to open the airway directly to the atmosphere. These regulations mandate visual observation as an exclusive option for detecting breathing efforts. However, reliance on visual observation alone can pose challenges in identifying subtle respiratory movements. CASE PRESENTATION: This case report presents a 55-year-old morbidly obese male patient with suspected BD due to cerebral hemorrhage undergoing an AT. The AT was performed with continuous electrical impedance tomography (EIT) monitoring. Upon detection of spontaneous breathing movements by both visual observation and EIT, the AT was aborted, and the patient was reconnected to the ventilator. EIT indicated a shift in ventilation distribution from the ventral to the dorsal regions, indicating the presence of spontaneous breathing efforts. EIT results also suggested the patient experienced a slow but transient initial recovery phase, likely due to atelectasis induced by morbid obesity, before returning to a steady state of ventilatory support. CONCLUSION: The findings suggest EIT could enhance the sensitivity and accuracy of detecting spontaneous breathing efforts, providing additional insights into the respiratory status of patients during the AT.

ABSTRACT

BACKGROUND: The apnea test (AT) plays a vital role in diagnosing brain death by evaluating the absence of spontaneous respiratory activity. It entails disconnecting the patient from mechanical ventilation to raise the CO2 partial pressure and lower the pH. Occasionally, the AT is aborted because of safety concerns, such as hypoxemia and hemodynamic instability, to prevent worsening conditions. However, the exact oxygen partial pressure level needed before commencing AT, indicating an inability to tolerate the test, is still uncertain. This study seeks to determine pre-AT oxygen levels linked with a heightened risk of test failure. METHODS: We conducted a retrospective cohort study involving patients suspected of having brain death at the Tel Aviv Medical Center from 2010 to 2022. The primary outcome was defined as an arterial partial O2 pressure (PaO2) level of 60 mmHg or lower at the conclusion of the AT. This threshold is significant because it marks the point at which the saturation curve deflects, potentially leading to rapid deterioration in the patient's oxygen saturation. RESULTS: Among the 70 patients who underwent AT, 7 patients met the primary diagnostic criteria. Patients with a PaO2 ≤ 60 mmHg at the conclusion of the AT exhibited a significantly lower initial median PaO2 of 243.7 mmHg compared with those with higher pre-AT PaO2 levels of 374.8 mmHg (interquartile range 104.65-307.00 and interquartile range 267.8-444.9 respectively, P value = 0.0041). Pre-AT PaO2 levels demonstrated good discriminatory ability for low PaO2 levels according to the receiver operating characteristic (ROC) curve, with an area under the curve of 0.76 (95% confidence interval 0.52-0.99). CONCLUSIONS: PaO2 values at the conclusion of the AT are closely associated with PaO2 values at the beginning of the test. Establishing a cutoff value of approximately 300 mmHg PaO2 at the onset of AT may assist in avoiding saturation drops below 90%.

ABSTRACT

BACKGROUND: Brain death has been used to decide whether to keep sustained care and treatment. It can facilitate tissue, organ, and body donation for several purposes, such as transplantation and medical education and research. In Japan, brain death has strict diagnostic criteria and family consent is crucial, but it has been a challenging concept for the public since its introduction, including knowledge and communication issues. OBJECTIVE: We analyzed data across YouTube and Twitter in Japan to uncover actors and assess the quality of brain death communication, providing recommendations to communicate new medical technologies. METHODS: Using the keyword "" (brain death), we collected recent data from YouTube and Twitter, classifying the data into 5 dimensions: time, individuality (type of users), place, activity, and relations (hyperlinks). We employed a scale to evaluate brain death information quality. We divided YouTube videos into 3 groups and assessed their differences through statistical analysis. We also provided a text-based analysis of brain death-related narratives. RESULTS: Most videos (20/61, 33%) were uploaded in 2019, while 10,892 tweets peaked between July 3 and 9, 2023, and June 12 and 18, 2023. Videos about brain death were mostly uploaded by citizens (18/61, 27%), followed by media (13/61, 20%) and unknown actors (10/61, 15%). On the other hand, most identified users in a random sample of 100 tweets were citizens (73/100, 73%), and the top 10 retweeted and liked tweets were also mostly authored by citizens (75/100, 75%). No specific information on location was uncovered. Information videos contained guides for accreditation of the National Nursing Exam and religious points of view, while misinformation videos mostly contained promotions by spirituality actors and webtoon artists. Some tweets involved heart transplantation and patient narratives. Most hyperlinks pointed to YouTube and Twitter. CONCLUSIONS: Brain death has become a common topic in everyday life, with some actors disseminating high-quality information, others disseminating no medical information, and others disseminating misinformation. Recommendations include partnering with interested actors, discussing medical information in detail, and teaching people to recognize pseudoscience.

ABSTRACT

Introduction: Providers across multiple specialties may be called upon to perform brain death assessments at hospitals that lack specialty neurology or critical care services. To address this need, we developed a brain death curriculum involving simulation and group discussion to prepare medical trainees for brain death testing and communication with surrogate decision-makers. Methods: A 1-hour session was delivered to trainees rotating through the intensive care unit at William Beaumont University Hospital. One trainee per session participated in a simulation involving a brain-dead patient (SimMan 3G Mannequin) and spouse (confederate) while the remainder of the cohort observed from a separate room. The trainee briefed the spouse about the brain death examination, performed the examination, and communicated their findings. Afterward, the cohort discussed the history, law, and common ethical and communication issues that surround brain death. Results: A total of 35 trainees participated from August 2022 to March 2023. After the session, trainees were more comfortable performing brain death testing (p < .001), responding to ethical issues (p < .001), and communicating with families (p < .001). However, the session did not change their frustration with family members who have a circulatory (p = .72) or high brain (p = .52) view of death. Discussion: The simulation had a positive impact on medical trainees' ability to perform brain death testing and their comfort level in discussing complex ethical issues that surround brain death. Our results support continued simulation training for medical trainees to better prepare them for clinical practice.

ABSTRACT

Background Despite clear definitions of brain death, students and medical professionals may have varying understandings. This study investigated the knowledge and attitudes of medical students regarding brain death. Methods A cross-sectional survey was administered to 142 fourth-year medical students at Umm Al-Qura University. The survey used single-choice and Likert scale questions to assess knowledge of brain death definition, diagnosis procedures, and student attitudes. Prior to administration, the questionnaire underwent content validation by experts in medicine, ethics, and public health. Results A significant proportion of students lacked knowledge of the legal definition of brain death in Saudi Arabia (26.1%), brain death diagnostic procedures (43.7%), and prerequisites for declaring brain death (38%). While some students expressed confidence in diagnosing brain death, concerns about misdiagnosis were also present. Conclusion Fourth-year medical students in this study demonstrated significant knowledge gaps regarding brain death. Medical education programs may need to be revised to provide more comprehensive training on brain death and its implications. Additionally, public awareness campaigns could improve understanding and facilitate informed decision-making about organ donation. Further research, including multicenter studies, is warranted to confirm these findings and guide educational interventions.

ABSTRACT

BACKGROUND: This study aimed to analyze the current status of brain death/death by neurologic criteria (BD/DNC) determination in Korea over a decade, identifying key areas for improvement in the process. METHODS: We conducted a retrospective analysis of data from the Korea Organ Donation Agency spanning 2011 to 2021, focusing on donors whose donations were not completed. The study reviewed demographics, medical settings, diagnoses, and outcomes, with particular emphasis on cases classified as nonbrain death and those resulting in death by cardiac arrest during the BD/DNC assessment. RESULTS: Of the 5047 patients evaluated for potential brain death from 2011 to 2021, 361 were identified as noncompleted donors. The primary reasons for noncompletion included nonbrain death (n = 68, 18.8%), cardiac arrests during the BD/DNC assessment process (n = 80, 22.2%), organ ineligibility (n = 151, 41.8%), and logistical and legal challenges (n = 62, 17.2%). Notably, 25 (36.8%) of them failed to meet the minimum clinical criteria, and 7 of them were potential cases of disagreement between the two clinical examinations. Additionally, most cardiac arrests (n = 44, 55.0%) occurred between the first and second examinations, indicating management challenges in critically ill patients during the assessment period. CONCLUSIONS: Our study highlights significant challenges in the BD/DNC determination process, including the need for improved consistency in neurologic examinations and the management of critically ill patients. The study underscores the importance of refining protocols and training to enhance the accuracy and reliability of brain death assessments, while also ensuring streamlined and effective organ donation practices.

ABSTRACT

BACKGROUND: In Japan, there has never been a national analysis of pediatric deceased donor liver transplantation (pDDLT) based on donor and recipient factors. We constructed a Japanese nationwide database and assessed outcomes of pDDLT focusing on the pediatric prioritization system introduced in 2018. METHODS: We collected data on pDDLTs (<18 years) performed between 1999 and 2021 from the Japan Organ Transplant Network and Japanese Liver Transplantation Society, identified risk factors for graft survival and compared the characteristics and graft survival in pDDLTs conducted before and after the introduction of the pediatric prioritization system. RESULTS: Overall, 112 cases of pDDLT were included, with a 1-year graft survival rate of 86.6%. Four poor prognostic factors were identified: recipient intensive care unit stay, model for end-stage liver disease/pediatric end-stage liver disease score, donor cause of death, and donor total bilirubin. After the introduction of the system, allografts from pediatric donors were more reliably allocated to pediatric recipients and the annual number of pDDLTs increased. The 1-year graft survival rate improved significantly as did pDDLT conditions indicated by the risk factors. CONCLUSIONS: Under the revised allocation system, opportunities for pDDLT increased, resulting in favorable recipient and donor conditions and improved survival.

ABSTRACT

BACKGROUND: Neurologically critically ill patients present with unique disease trajectories, prognostic uncertainties, and challenges to end-of-life (EOL) care. Acute brain injuries place these patients at risk for underrecognized symptoms and unmet EOL management needs, which can negatively affect their quality of care and lead to complicated grief in surviving loved ones. To care for patients nearing the EOL in the neurointensive care unit, health care clinicians must consider neuroanatomic localization, barriers to symptom assessment and management, unique aspects of the dying process, and EOL management needs. AIM: We aim to define current best practices, barriers, and future directions for EOL care of the neurologically critically ill patient.

ABSTRACT

INTRODUCTION: The need for end-of-life care is common in intensive care units (ICUs). Although guidelines exist, little is known about actual end-of-life care practices in Hong Kong ICUs. The study aim was to provide a detailed description of these practices. METHODS: This prospective, multicentre observational sub-analysis of the Ethicus-2 study explored end-of-life practices in eight participating Hong Kong ICUs. Consecutive adult ICU patients admitted during a 6-month period with life-sustaining treatment (LST) limitation or death were included. Follow-up continued until death or 2 months from the initial decision to limit LST. RESULTS: Of 4922 screened patients, 548 (11.1%) had LST limitation (withholding or withdrawal) or died (failed cardiopulmonary resuscitation/brain death). Life-sustaining treatment limitation occurred in 455 (83.0%) patients: 353 (77.6%) had decisions to withhold LST and 102 (22.4%) had decisions to withdraw LST. Of those who died without LST limitation, 80 (86.0%) had failed cardiopulmonary resuscitation and 13 (14.0%) were declared brain dead. Discussions of LST limitation were initiated by ICU physicians in most (86.2%) cases. Shared decision-making between ICU physicians and families was the predominant model; only 6.0% of patients retained decision-making capacity. Primary medical reasons for LST limitation were unresponsiveness to maximal therapy (49.2%) and multiorgan failure (17.1%). The most important consideration for decision-making was the patient's best interest (81.5%). CONCLUSION: Life-sustaining treatment limitations are common in Hong Kong ICUs; shared decision-making between physicians and families in the patient's best interest is the predominant model. Loss of decision-making capacity is common at the end of life. Patients should be encouraged to communicate end-of-life treatment preferences to family members/surrogates, or through advance directives.

ABSTRACT

Brain death (BD) is a complex medical state that triggers systemic disturbances and a cascade of pathophysiological processes. This condition significantly impairs both kidney function and structural integrity, thereby presenting considerable challenges to graft viability and the long-term success of transplantation endeavors. Tacrolimus (FK506), an immunosuppressive drug, was used in this study to assess its impact as a pretreatment on brain death-induced renal injury. This study aimed to investigate changes associated with brain death-induced renal injury in a 4-month-old female porcine model. The experimental groups included brain death placebo-pretreated (BD; n = 9), brain death tacrolimus-pretreated using the clinical dose of 0.25 mg/kg the day before surgery, followed by 0.05 mg/kg/day 1 hour before the procedure (BD + FK506; n = 8), and control (ctrl, n = 7) piglets, which did not undergo brain death induction. Furthermore, we aimed to assess the effect of FK506 on these renal alterations through graft preconditioning. We hypothesized that immunosuppressive properties of FK506 reduce tissue inflammation and preserve the glycocalyx. Our findings revealed a series of interconnected events triggered by BD, leading to a deterioration of renal function and increased proteinuria, increased apoptosis in the vessels, glomeruli and tubules, significant leukocyte infiltration into renal tissue, and degradation of the glycocalyx in comparison with ctrl group. Importantly, treatment with FK506 demonstrated significant efficacy in attenuating these adverse effects. FK506 helped reduce apoptosis, maintain glycocalyx integrity, regulate neutrophil infiltration, and mitigate renal injury following BD. This study offers new insights into the pathophysiology of BD-induced renal injury, emphasizing the potential of FK506 pretreatment as a promising therapeutic intervention for organ preservation, through maintaining endothelial function with the additional benefit of limiting the risk of rejection.

ABSTRACT

Much of the debate over the definition and criteria for determining our death has focused on disagreement over the correct biological account of death, i.e., what it means for any organism to die. In this paper, we argue that this exclusive focus on the biology of death is misguided, because it ignores ethical and social factors that bear on the acceptability of criteria for determining our death. We propose that attention shift from strictly biological considerations to ethical and social considerations that bear on the determination of what we call "civil death." We argue for acceptance of a neurological criterion for determining death on grounds that it is the most reasonable way to synthesize biological, ethical, and social considerations about our death..

ABSTRACT

BACKGROUND: With an ongoing demand for transplantable organs, optimization of donor management protocols, specifically in trauma populations, is important for obtaining a high yield of viable organs per patient. Endocrine management of brain-dead potential organ donors (BPODs) is controversial, leading to heterogeneous clinical management approaches. Previous studies have shown that when levothyroxine was combined with other treatments, including steroids, vasopressin, and insulin, BPODs had better organ recovery and survival outcomes were increased for transplant recipients. AIM: To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients. METHODS: A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed. Exclusion criteria included patients who were not solid organ donors, patients who were not declared brain dead (donation after circulatory death), and patients who did not receive steroids in their hospital course. Levothyroxine and steroid administration, the number of organs donated, the types of organs donated, and demographic information were recorded. Univariate analyses were performed with P < 0.05 considered to be statistically significant. RESULTS: A total of 88 patients met inclusion criteria, 69 (78%) of whom received levothyroxine and steroids (ST/LT group) vs 19 (22%) receiving steroids without levothyroxine (ST group). No differences were observed between the groups for gender, race, pertinent injury factors, age, or other hormone therapies used (P > 0.05). In the ST/LT group, 68.1% (n = 47) donated a high yield (3-5) of organ types per donor compared to 42.1% (n = 8) in the ST group (P = 0.038). There was no difference in the total number of organ types donated between the groups (P = 0.068). CONCLUSION: This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population. Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria. This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.

ABSTRACT

The development of critical care stimulated brain death criteria formulation in response to concerns on treatment resources and unregulated organ procurement. The diagnosis centered on irreversible loss of brain function and subsequent systemic physiologic collapse and was subsequently codified into law. With improved critical care, physiologic collapse (while predominant) is not inevitable-provoking criticisms of the ethical and legal foundation for brain death. Other criteria have been unsuccessfully proposed, but irreversibility remains the conceptual foundation. Conflicts can arise when families reject the diagnosis-resulting in ethical, cultural, and communication challenges and implications for diversity, equity, and inclusion.

ABSTRACT

Efforts to revise the Uniform Determination of Death Act in order to align law with medical practice have failed. Medical practice must now align with the law. People who are not dead under the law that defines death should not be declared dead. There is no compelling reason to continue the practice of declaring legally living persons to be dead.

ABSTRACT

The determination of death by neurological criteria (DNC) stands as a pivotal aspect of medical practice, involving a nuanced clinical diagnosis. Typically, it comes into play following a devastating brain injury, signalling the irreversible cessation of brain function, marked by the absence of consciousness, brainstem reflexes, and the ability to breathe autonomously. Accurate DNC diagnosis is paramount for adhering to the 'Dead donor rule', which permits organ donation solely from deceased individuals. However, complexities inherent in conducting a comprehensive DNC examination may impede reaching a definitive diagnosis. To address this challenge, ancillary testing such as computed tomography angiography (CTA) has emerged as a valuable tool. The aim of our study is to review the technique and interpretation of CTA for DNC diagnoses. CTA, a readily available imaging technique, enables visualization of the cerebral vasculature, offering insights into blood flow to the brain. While various criteria and scoring systems have been proposed, a universally accepted standard for demonstrating full brain circulatory arrest remains elusive. Nonetheless, leveraging CTA as an ancillary test in DNC assessments holds promise, facilitating organ donation and curbing healthcare costs. It is crucial to emphasize that DNC diagnosis should be exclusively entrusted to trained physicians with specialized DNC evaluation training, underscoring the importance of expertise in this intricate medical domain.

ABSTRACT

Craniotomy or decompressive craniectomy are among the therapeutic options to prevent or treat secondary damage after severe brain injury. The choice of procedure depends, among other things, on the type and severity of the initial injury. It remains controversial whether both procedures influence the neurological outcome differently. Thus, estimating the risk of brain herniation and death and consequently potential organ donation remains difficult. All patients at the University Hospital Münster for whom an isolated craniotomy or decompressive craniectomy was performed as a treatment after severe brain injury between 2013 and 2022 were retrospectively included. Proportion of survivors and deceased were evaluated. Deceased were further analyzed regarding anticoagulants, comorbidities, type of brain injury, potential and utilized donation after brain death. 595 patients were identified, 296 patients survived, and 299 deceased. Proportion of decompressive craniectomy was higher than craniotomy in survivors (89% vs. 11%, p < 0.001). Brain death was diagnosed in 12 deceased and 10 donations were utilized. Utilized donations were comparable after both procedures (5% vs. 2%, p = 0.194). Preserved brain stem reflexes as a reason against donation did not differ between decompressive craniectomy or craniotomy (32% vs. 29%, p = 0.470). Patients with severe brain injury were more likely to survive after decompressive craniectomy than craniotomy. Among the deceased, potential and utilized donations did not differ between both procedures. This suggests that brain death can occur independent of the previous neurosurgical procedure and that organ donation should always be considered in end-of-life decisions for patients with a fatal prognosis.
