ABSTRACT

BACKGROUND: How individuals are informed of the traumatic loss of a loved one can influence their grieving process and quality of life. OBJECTIVE: This qualitative study aimed to explore, through thematic analysis, how life stages might influence the experience and feelings of those who have received communication of a traumatic death from police officers or healthcare professionals. METHOD: Recruited through social networks and word of mouth, 30 people participated in the study. Subjects were divided into three groups according to age (Group 1: ten participants aged between 20 and 35 years; Group 2: ten participants aged between 45 and 55 years; and Group 3: ten participants aged 60 and over). Participants completed an ad hoc questionnaire online. Atlas.ti software 8 was used to perform thematic analysis. RESULTS: The three age groups had the following four key themes in common: (a) emotional reactions; (b) subjective valuation of the notification; (c) support; and (d) needs. Subtle differences emerged between age groups; yet the quality of the reactions and main themes did not vary greatly between the groups considered. CONCLUSIONS: The communication of an unexpected and violent death seems to provoke rather similar effects in survivors of different life stages. A few differences were noted in sub-themes (increased need for professional training in younger recipients; absence of suicidal ideation in older adults); perhaps quantitative designs could provide further details in future investigations.

ABSTRACT

The small apes, gibbons and siamangs, are monogamous species with their social groups comprising of both parents and their offspring. Therefore, the loss of a member may elicit a stress response in the remaining members due to their strong bonds. Glucocorticoids (GCs) have been useful indicators of stress, but distinguishing between acute versus chronic stress may be limited when measuring these hormones alone. The adrenal hormone dehydroepiandrosterone-sulfate (DHEAS), a GC antagonist, has been implicated in the regulation of the stress response. Thus, the concomitant measurement of these hormones can help examine whether an event, such as the loss of a group member, elicited a stress response. In this brief report, we discuss the hormonal response of two zoo-housed northern white-cheeked gibbons (Nomascus leucogenys) (1 adolescent male and his mother) after the death of the adult male of the group. Baseline fecal samples were collected opportunistically from these two individuals 5 months prior, and 3 months following the death of their group member. A total of 25 samples were quantified for fecal GC metabolites (FGCMs) and DHEAS by enzyme immunoassay (EIA) to calculate the FGCMs:DHEAS ratio. Our results indicate an increase in FGCMs and FGCMs:DHEAS for the adolescent male, but not the adult female, following the death. Our findings suggest that the integration of FGCMs and DHEAS measurements can provide valuable information to interpret individual stress levels to the sudden change in the group's social structure.

ABSTRACT

Heart transplantation is the definitive treatment for refractory, end-stage heart failure. The number of patients awaiting transplantation far exceeds available organs. In an effort to expand the donor pool, donation after circulatory death (DCD) heart transplantation has garnered renewed interest. Unlike donation after brain death, DCD donors do not meet the criteria for brain death and are dependent on life-sustaining therapies. Procurement can include a direct strategy or a normothermic regional perfusion, whereby there is restoration of perfusion to the organ before explantation. There are new developments in cold storage and ex vivo perfusion strategies. Since its inception, there has been a steady improvement in post-transplant outcomes, largely attributed to advancements in operative and procurement strategies. In this narrative review, the authors address the unique considerations of DCD heart transplantation, including withdrawal of care, the logistics of procuring and resuscitating organs, outcomes compared with standard donation after brain death, and ethical considerations.

ABSTRACT

The introduction of normothermic regional perfusion (NRP) in controlled donation after circulatory determination of death (cDCDD) protocols is by some regarded as controversial and ethically troublesome. One of the main concerns that opponents have about introducing NRP in cDCDD protocols is that reestablishing circulation will negate the determination of death by circulatory criteria, potentially resuscitating the donor. In this article, I argue that this is not the case. If we take a closer look at the concept of death underlying the circulatory criterion for determination of death, we find that the purpose of the criterion is to show whether the organism as a whole has died. I argue that this purpose is fulfilled by the circulatory criterion in cDCDD protocols, and that applying NRP does not negate the determination of death or resuscitate the donor.

ABSTRACT

Donation after circulatory determination of death (DCDD) is an accepted practice in the United States, but heart procurement under these circumstances has been debated. Although the practice is experiencing a resurgence due to the recently completed trials using ex vivo perfusion systems, interest in thoracoabdominal normothermic regional perfusion (TA-NRP), wherein the organs are reanimated in situ prior to procurement, has raised many ethical questions. We outline practical, ethical, and equity considerations to ensure transplant programs make well-informed decisions about TA-NRP. We present a multidisciplinary analysis of the relevant ethical issues arising from DCDD-NRP heart procurement, including application of the Dead Donor Rule and the Uniform Definition of Death Act, and provide recommendations to facilitate ethical analysis and input from all interested parties. We also recommend informed consent, as distinct from typical "authorization," for cadaveric organ donation using TA-NRP.

ABSTRACT

An adult university hospital ethics committee evaluated a proposed TA-NRP protocol in the fall of 2018. The protocol raised ethical concerns about violation of the Uniform Determination of Death Act and the prohibition known as the Dead Donor Rule, with potential resultant legal consequences. An additional concern was the potential for increased mistrust by the community of organ donation and transplantation. The ethics committee evaluated the responses to these concerns as unable to surmount the ethical and legal boundaries and the ethics committee declined to endorse the procedure. These concerns endure.

ABSTRACT

Organ donation after the circulatory determination of death requires the permanent cessation of circulation while organ donation after the brain determination of death requires the irreversible cessation of brain functions. The unified brain-based determination of death connects the brain and circulatory death criteria for circulatory death determination in organ donation as follows: permanent cessation of systemic circulation causes permanent cessation of brain circulation which causes permanent cessation of brain perfusion which causes permanent cessation of brain function. The relevant circulation that must cease in circulatory death determination is that to the brain. Eliminating brain circulation from the donor ECMO organ perfusion circuit in thoracoabdominal NRP protocols satisfies the unified brain-based determination of death but only if the complete cessation of brain circulation can be proved. Despite its medical and physiologic rationale, the unified brain-based determination of death remains inconsistent with the Uniform Determination of Death Act.

ABSTRACT

BACKGROUND: Italy presently does not have a pediatric organ donation program after cardiocirculatory determination of death (pDCDD). Before implementing a pDCDD program, many centers globally have conducted studies on the attitudes of pediatric intensive care unit (PICU) staff. This research aims to minimize potential adverse reactions and evaluate the acceptance of the novel donation practice. METHODS: We conducted an electronic and anonymous survey on attitudes toward pDCDD among healthcare professionals (HCPs) working at eight Italian PICUs. The survey had three parts: (I) questions about general demographic data; (II) 18 statements about personal wishes to donate, experience of discussing donation, and knowledge about donation; (III) attitudinal statements regarding two pediatric Maastricht III scenarios of organ donation. RESULTS: The response rate was 54.4%, and the majority of respondents were nurses. Of those who responded, 45.3% worked in the Center, 40.8% in the North, and 12.8% in the South of Italy. In total, 93.9% supported pediatric organ and tissue donation, 90.3% supported donation after neurological determination of death (DNDD), 78.2% supported pDCDD, and 69.7% felt comfortable about the idea of participating in pDCDD on Type III patients, with a higher percentage of supportive responses in the Center (77.2%) than in the North (65.1%) and South (54.5%) of Italy (p-value < 0.004). Concerning scenarios, 79.3% of participants believed that organ retrieval took place in a patient who was already deceased. Overall, 27.3% considered their knowledge about DCDD to be adequate. CONCLUSIONS: Our study provides insight into the attitudes and knowledge of PICU staff members regarding pDCDD in Italy. Despite a general lack of knowledge on the subject, respondents showed positive attitudes toward pDCDD and a strong consensus that the Italian legislation protocol for determining death based on cardiocirculatory criteria respects the "dead donor rule." There were several distinctions among the northern, central, and southern regions of Italy, and in our view, these disparities can be attributed to the varying practices of commemorating the deceased. In order to assess how practice and training influence the attitude of PICU staff members, it would be interesting to repeat the survey after the implementation of a program.

ABSTRACT

BACKGROUND: Disability prior to death complicates end-of-life care. The present study aimed to explore the prior-to-death disability profiles of Chinese older adults, the profiles' links to end-of-life care arrangements and place of death, and predictors of the profiles. METHODS: In total, data were extracted from the records of 10,529 deceased individuals from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Latent profile analyses, bivariate analysis, and multivariate logistic regression were applied to identify prior-to-death disability profiles, explore the profiles' links to end-of-life care arrangements and place of death, and examine predictors in the profiles, respectively. RESULTS: Three prior-to-death disability profiles, namely, Disabled-Incontinent (37.6%), Disabled-Continent (34.6%), and Independent (27.8%), were identified. Those with the Independent profile were more likely to live alone or with a spouse and receive no care or care only from the spouse before death. Disabled-Continent older adults had a higher chance of dying at home. Being female, not "married and living with a spouse", suffering from hypertension, diabetes, stroke or cerebrovascular disease (CVD), bronchitis/emphysema/pneumonia, cancer, or dementia, and dying in a later year were associated with more severe prior-to-death disability patterns. Not having public old-age insurance predicted lower chances of having a Disabled-Incontinent profile, and advanced age increased the chance of having a Disabled-Continent profile. CONCLUSIONS: Three prior-to-death disability patterns were identified for Chinese adults aged 65 years and older. These profiles were significantly linked with the end-of-life caregiving arrangements and place of death among older adults. Both demographic information and health status predicted prior-to-death disability profiles.
