Project description:A recent commentary defends 1) the concept of 'brain arrest' to explain what brain death is, and 2) the concept that death occurs at 2-5 minutes after absent circulation. I suggest that both these claims are flawed. Brain arrest is said to threaten life, and lead to death by causing a secondary respiratory then cardiac arrest. It is further claimed that ventilation only interrupts this way that brain arrest leads to death. These statements imply that brain arrest is not death itself. Brain death is a devastating state that leads to death when intensive care, which replaces some of the brain's vital functions such as breathing, is withdrawn and circulation stops resulting in irreversible loss of integration of the organism. Circulatory death is said to occur at 2-5 minutes after absent circulation because, in the context of DCD, the intent is to not attempt reversal of the absent circulation. No defense of this weak construal of irreversible loss of circulation is given. This means that patients in identical physiologic states are dead (in the DCD context) or alive (in the resuscitation context); the current state of death (at 2-5 minutes) is contingent on a future event (whether there will be resuscitation) suggesting backward causation; and the commonly used meaning of irreversible as 'not capable of being reversed' is abandoned. The literature supporting the claim that autoresuscitation does not occur in the context of no cardiopulmonary resuscitation is shown to be very limited. Several cases of autoresuscitation are summarized, suggesting that the claim that these cases are not applicable to the current debate may be premature. I suggest that brain dead and DCD donors are not dead; whether organs can be harvested before death from these patients whose prognosis is death should be debated urgently.

Project description:BackgroundWe aimed to investigate the extent of the agreement on practices around brain death and postmortem organ donation.MethodsInvestigators from 67 Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study centers completed several questionnaires (response rate: 99%).ResultsRegarding practices around brain death, we found agreement on the clinical evaluation (prerequisites and neurological assessment) for brain death determination (BDD) in 100% of the centers. However, ancillary tests were required for BDD in 64% of the centers. BDD for nondonor patients was deemed mandatory in 18% of the centers before withdrawing life-sustaining measures (LSM). Also, practices around postmortem organ donation varied. Organ donation after circulatory arrest was forbidden in 45% of the centers. When withdrawal of LSM was contemplated, in 67% of centers the patients with a ventricular drain in situ had this removed, either sometimes or all of the time.ConclusionsThis study showed both agreement and some regional differences regarding practices around brain death and postmortem organ donation. We hope our results help quantify and understand potential differences, and provide impetus for current dialogs toward further harmonization of practices around brain death and postmortem organ donation.

Project description:ObjectivesTo determine whether end-of-life (EOL) experiences in the first spouse in a marriage are associated with EOL experiences in the other spouse.DesignNationally representative, longitudinal survey.SettingHealth and Retirement Study, Waves 1992-2012 linked to Medicare claims PARTICIPANTS: Community-dwelling older adults who died (N=4,558), representing 2,279 married heterosexual couples.MeasurementsWe examined 3 EOL experiences: enrollment in hospice for >3 days before death, lack of advance care planning (ACP) before death, and intensive care unit (ICU) use during the last 30 days of life. We used multiple logistic regression to determine whether the EOL experience of the first spouse was a significant predictor of the EOL experience of the second spouse after adjusting for demographic characteristics, socioeconomic status, health status, and time between the first and second spouses' deaths.ResultsFirst spouses who died were on average 80 years old, and 62% were male; second spouses were on average 85 years old, and 62% were female. After adjustment, second spouses were more likely to use hospice if the first spouse used hospice (odds ratio (OR)=1.68, 95% confidence interval (CI)=1.29-2.20). Second spouses were less likely to have ACP when the first spouse did not have ACP (OR=2.91, 95% CI=2.02-4.21). Hospice and ACP associations were stronger when deaths were closer in time to one another (p-value for interaction < .05). Second spouses were more likely to use ICU services if the first spouse did (OR=1.80, 95% CI=1.27-2.55).ConclusionsThe EOL experiences of older spouses are strongly associated, which may be relevant when framing ACP discussions.

Project description:PurposeTo evaluate the effectiveness, efficiency, and safety of a transnational gamete donation (TGD) programme based on the shipping of vitrified donor oocytes.MethodsA retro-prospective observational study was conducted in the Assisted Reproductive Technology Center of the University Hospital of Florence, Italy. The study population included 622 consecutive donor oocyte cycles. A mean number of 6 vitrified oocytes per couple were shipped from two Spanish biobanks. In the receiving centre, gametes were warmed and inseminated and the subsequent embryo transfer (ET) was performed. The main outcome measurement was LBR. Secondary outcomes included oocyte survival rate, ICSI damage rate, normal fertilization, cleavage, and implantation rate (IR) in both 'fresh' and cryotransfer cycles.ResultsA total number of 3536 mature oocytes were warmed with 81.4% surviving oocytes. 2PN oocytes were 1941 with an ICSI normal fertilization rate of 70.4% and a cleavage rate of 93.4%; 857 day-3 embryos were transferred in 498 women, 63 blastocysts in 44. Couples with at least one vitrified embryo were 181 (32.3%). IR was 25.1% and 33.1% for day-3 ET and blastocyst stage respectively. Crude pregnancy rate and LBR after the first ET were 35.5% and 27% correspondingly with a conservative cumulative LBR of 34% and an optimal LBR of 51.4%.ConclusionImported vitrified donor oocytes retain their competence and are capable of resulting in ongoing pregnancies and healthy babies in a proportion comparable to other existing systems as egg donation with vitrification/warming in the same laboratory and transnational fresh oocyte donation.

Project description:PurposeResearch using gametes and embryos donated by reproductive and third-party donors contributed to substantial, albeit contentious achievements. The views of gamete donors and recipients on donation for research and the underpinning role of attitudes towards research have been seldom explored and are yet to be incorporated into ethical, legal, and regulatory landscapes. From a cultural standpoint, this study adapts and explores psychometric properties of the Portuguese version of the Research Attitudes Questionnaire (RAQ), and analyzes the willingness of gamete donors and recipients to donate gametes and embryos for research and its association with sociodemographic, reproductive characteristics, and attitudes towards research.MethodsBetween July 2017 and June 2018, 71 donors and 165 recipients completed a self-administered questionnaire at the Portuguese Public Bank of Gametes. Willingness to donate and attitudes towards research were measured with a 5-point Likert scale. RAQ psychometric characteristics were explored.ResultsTwo RAQ components were identified: "trustworthiness of research" and "critical perspective". Most participants were willing to donate gametes and embryos: donors more willing to donate gametes and male recipients more willing to donate gametes and embryos. Higher RAQ scores, indicating a more positive attitude towards research, were observed on the component "trustworthiness of research" among those willing to donate gametes and embryos and on the component "critical perspective" among those willing to donate embryos.ConclusionThese findings help foster inclusivity, diversity, and responsiveness of research and call for upstream engagement of male and female gamete donors and recipients, promoting a trustworthy, anticipatory, democratic, and people-centered approach to policies, regulations, and practices in human gamete and embryo research.

Project description:Access to postmortem brain tissue can be valuable in refining knowledge on the pathophysiology and genetics of neuropsychiatric disorders. Obtaining postmortem consent for the donation after death by suicide can be difficult, as families may be overwhelmed by a violent and unexpected death. Examining the process of brain donation can inform on how the request can best be conducted. This is a qualitative study with in-depth interviews with forty-one people that were asked to consider brain donation-32 who had consented to donation and 9 who refused it. Data collection and analyses were carried out according to grounded theory. Five key themes emerged from data analysis: the context of the families, the invitation to talk to the research team, the experience with the request protocol, the participants' assessment of the experience, and their participation in the study as an opportunity to heal. The participants indicated that a brain donation request that is respectful and tactful can be made without adding to the family distress brought on by suicide and pondering brain donation was seen as an opportunity to transform the meaning of the death and invest it with a modicum of solace for being able to contribute to research.

Project description:Increased African-American research participation is critical to the applicability and generalizability of biomedical research, as population diversity continues to increase both domestically and abroad. Yet numerous studies document historical origins of mistrust, as well as other barriers that may contribute to resistance in the African-American community towards participation in biomedical research. However, a growing body of more recent scientific evidence suggests that African-Americans value research and are willing to participate when asked. In the present study, we set out to determine factors associated with research participation of African-American families in postmortem human brain tissue donation for neuropsychiatric disorders as compared with Caucasian families, from same-day medical examiner autopsy referrals. We retrospectively reviewed brain donation rates, as well as demographic and clinical factors associated with donation in 1,421 consecutive referrals to three medical examiner's offices from 2010-2015. Overall, 69.7% of all next-of-kin contacted agreed to brain donation. While Caucasian families consented to donate brain tissue at a significantly higher rate (74.1%) than African-American families (57.0%) (p<0.001), African-American brain donation rates were as high as 60.5% in referrals from Maryland. Neither African-American nor Caucasian donors differed significantly from non-donors on any demographic or clinical factors ascertained, including age, sex, diagnosis of the donor, or in the relationship of the next-of-kin being contacted (p>0.05). However, Caucasian donors were significantly older, had more years of education, were more likely to be referred for study due to a psychiatric diagnosis, more likely to have comorbid substance abuse, and more likely to have died via suicide, as compared with African-American donors (p<0.05). When African-American participants are identified and approached, African-American families as well as Caucasian families are indeed willing to donate brain tissue on the spot for neuropsychiatric research, which supports the belief that African-American attitudes towards biomedical research may be more favorable than previously thought.

Project description:ImportanceParents who experience neonatal loss have the option to participate in autopsy, organ donation, and research donation. However, clinicians are uncomfortable discussing autopsy and may not be aware of research and organ donation opportunities.ObjectiveTo capture the perspectives of parents who had experienced neonatal loss about autopsy, organ donation, and research donation.Design, setting, and participantsThis qualitative study used virtual focus groups with parents who attended a local bereavement support group in the US. Participants were recruited from Helping After Neonatal Death, a support group with a local chapter. Participants self-selected from an email request if they met the following criteria: aged 18 years or older, English speaking, at least 6 months elapsed since neonatal death, and access to a video conference device with internet. Focus groups took place between April and September 2021. The recorded sessions were analyzed using a grounded theory-informed approach by the research team that included parents with experience of neonatal loss. Data were analyzed from December 2021 through December 2022.ResultsA total of 14 mothers engaged in the focus group; 9 (75%) were aged 30 to 39 years, and 8 (66%) were White. The mothers were overall well educated. The first main theme grew from the lived experience of neonatal loss, specifically the importance of offering all parents the option to donate, rather than prejudging who would or would not be interested. Parents of neonates who die have few opportunities to parent that child and make loving decisions for them. Participants emphasized that the conversation about autopsy, organ donation, and research donation, albeit difficult, can offer a meaningful parenting experience. A second main theme that emerged related to how organ or tissue donation could provide additional meaning to a child's life. These choices contributed to building a legacy to honor their child's memory, which also helped with grief and coping with their loss. A third theme included recommendations to clinicians and health systems for improving communication, including written information for parents and communication training for health care professionals.Conclusions and relevanceIn this qualitative study, parents who experienced neonatal loss endorsed the importance of offering parents the choice of autopsy, organ donation, or research donation with skillful and empathetic communication. They provided practical recommendations to improve communication and empower families.

Project description:The decision to use an anonymous gamete donation in fertility treatment could have significant long-term psychological and social effects for all stakeholders involved. In light of the growing recognition of donor-conceived children's right to know their genetic parentage, this entails profound ethical implications. This review aims to carve out the full spectrum of recipients' motives and experiences related to donor anonymity which could serve as an analytical framework for future ethical and sociological research on issues of donor anonymity. This review was conducted following a seven-step approach for systematic reviews of empirical bioethics literature. The characteristics and quality of the studies included in this review were reported. Data analysis was conducted using qualitative content analysis and was informed by sociological functionalist theorizations of ignorance. The 53 studies selected showed a diverse spectrum of characteristics concerning date and country of study, methodology, family type of participants, sample size, and the timing of data collection in relation to the stage of treatment. A total of 22 categories of motives and experiences of recipients concerning donor anonymity were identified inductively and grouped into five main categories. Donor anonymity was identified as a eufunctional form of ignorance, by which the recipients experienced or intended to control, regulate, or protect inter-stakeholder relations. Interpreting recipients' motives and experiences concerning donor anonymity as a form of ignorance directed toward particular stakeholders helps reframe the discourse on donor anonymity. It is a fruitful approach that can be refined further and applied in future research. This review identified possible directions for future investigations on motives for donor anonymity: the need for more thorough inquiries into the change in recipients' preferences over time, such as in the form of longitudinal studies and research on the perspective of non-biological parents.
