Near-death experiences after cardiac arrest: a scoping review.

BACKGROUND: This scoping review aimed to characterise near-death experiences in the setting of cardiac arrest, a phenomenon that is poorly understood and may have clinical consequences. METHOD: PubMed/MEDLINE was searched to 23 July 2023 for prospective studies describing near-death experiences in cardiac arrest. PRISMA-ScR guidelines were adhered to. Qualitative and quantitative data were synthesised. Meta-analysis was precluded due to data heterogeneity. RESULTS: 60 records were identified, of which 11 studies involving interviews were included from various countries. Sample size ranged from 28-344, and proportion of female patients (when reported) was 0-50%, with mean age (when reported) ranging 54-64 years. Comorbidities and reasons for cardiac arrest were heterogeneously reported. Incidence of near-death experiences in the included studies varied from 6.3% to 39.3%; with variation between in-hospital (6.3-39.3%) versus out-of-hospital (18.9-21.2%) cardiac arrest. Individual variables regarding patient characteristics demonstrated statistically significant association with propensity for near-death experiences. Reported content of near-death experiences tended to reflect the language of the questionnaires used, rather than the true language used by individual study participants. Three studies conducted follow-up, and all suggested a positive life attitude change, however one found significantly higher 30-day all-cause mortality in patients with near-death experiences versus those without, in non-controlled analysis. CONCLUSIONS: From prospective studies that have investigated the phenomenon, near-death experiences may occur in as frequent as over one-third of patients with cardiac arrest. Lasting effects may follow these events, however these could also be confounded by clinical characteristics.

Subcutaneous sodium valproate in palliative care: A systematic review.

BACKGROUND: Seizures are an important palliative symptom, the management of which can be complicated by patients' capacity to swallow oral medications. In this setting, and the wish to avoid intravenous access, subcutaneous infusions may be employed. Options for antiseizure medications that can be provided subcutaneously may be limited. Subcutaneous sodium valproate may be an additional management strategy. AIM: To evaluate the published experience of subcutaneous valproate use in palliative care, namely with respect to effectiveness and tolerability. DESIGN: A systematic review was registered (PROSPERO CRD42023453427), conducted and reported according to PRISMA reporting guidelines. DATA SOURCES: The databases PubMed, EMBASE and Scopus were searched for publications until August 11, 2023. RESULTS: The searches returned 429 results, of which six fulfilled inclusion criteria. Case series were the most common study design, and most studies included <10 individuals who received subcutaneous sodium valproate. There were three studies that presented results on the utility of subcutaneous sodium valproate for seizure control, which described it to be an effective strategy. One study also described it as an effective treatment for neuropathic pain. The doses were often based on presumed 1:1 oral to subcutaneous conversion ratios. Only one study described a local site adverse reaction, which resolved with a change of administration site. CONCLUSIONS: There are limited data on the use of subcutaneous sodium valproate in palliative care. However, palliative symptoms for which subcutaneous sodium valproate have been used successfully are seizures and neuropathic pain. The available data have described few adverse effects, supporting its use with an appropriate degree of caution.

Evolution of the sheep coat: the impact of domestication on its structure and development.

Wild sheep and many primitive domesticated breeds have two coats: coarse hairs covering shorter, finer fibres. Both are shed annually. Exploitation of wool for apparel in the Bronze Age encouraged breeding for denser fleeces and continuously growing white fibres. The Merino is regarded as the culmination of this process. Archaeological discoveries, ancient images and parchment records portray this as an evolutionary progression, spanning millennia. However, examination of the fleeces from feral, two-coated and woolled sheep has revealed a ready facility of the follicle population to change from shedding to continuous growth and to revert from domesticated to primitive states. Modifications to coat structure, colour and composition have occurred in timeframes and to sheep population sizes that exclude the likelihood of variations arising from mutations and natural selection. The features are characteristic of the domestication phenotype: an assemblage of developmental, physiological, skeletal and hormonal modifications common to a wide variety of species under human control. The phenotypic similarities appeared to result from an accumulation of cryptic genetic changes early during vertebrate evolution. Because they did not affect fitness in the wild, the mutations were protected from adverse selection, becoming apparent only after exposure to a domestic environment. The neural crest, a transient embryonic cell population unique to vertebrates, has been implicated in the manifestations of the domesticated phenotype. This hypothesis is discussed with reference to the development of the wool follicle population and the particular roles of Notch pathway genes, culminating in the specific cell interactions that typify follicle initiation.

Documenting the process of developing the Victorian voluntary assisted dying legislation.

Many countries across the world have legislated for their constituents to have control over their death. Commonalities and differences can be found in the regulations surrounding the shape and practices of voluntary assisted dying (VAD) and euthanasia, including an individual's eligibility and access, role of health professions and the reporting. In Australia there have been perennial debates across the country to attempt legislative change in assisting a terminally ill person to control the ending of their life. In 2017, Victoria became the first state to successfully legislate for VAD. In describing the Victorian process that led to the passage of legislation for VAD, this paper examines the social change process. The particular focus of the paper is on the vital role played by a multidisciplinary ministerial advisory panel to develop recommendations for the successful legislation, and is written from their perspective.

A palliative approach or specialist palliative care? What happens in aged care facilities for residents with a noncancer diagnosis?

This article presents results of the second stage of a research project which explored the palliative care needs of 69 residents with a noncancer diagnosis in South Australia. Extensive data were collected prospectively from case notes, and resident and staff interviews over a 10-week period. Residents were suffering multiple conditions and were highly dependent for activities of daily living. Most residents' care was consistent with a palliative approach, with only three residents in the study referred to a specialist palliative care service. However, for some residents, pain and symptom management were not always adequate, and referral to a specialist palliative care service would have been appropriate. This research indicates that, with additional education, it could be possible to extend the principles and philosophy of palliative care by adopting a palliative care approach within aged care facilities.

Documenting end of life decisions in residential aged care facilities in South Australia.

OBJECTIVE: This research examined the provision of palliative care for residents with a non-cancer diagnosis including the use of advance directives and advance care planning as part of palliative care policies in residential aged care facilities in South Australia. There are no guidelines for recording residents' wishes if they are no longer competent. METHODS: Stage 1 involved a survey of 90 randomly selected aged care facilities. Stage 2 involved case studies of 69 residents, appropriate for palliative care, from 17 facilities and interviews with 15 directors of care. RESULTS: Most residential aged care facilities used forms to record residents' wishes about end of life care, but there was little consistency. Some had no palliative care policy and few facilities required a formal advance directive. Not all residents had formally appointed a proxy. CONCLUSIONS: Residential aged care facilities should be required to develop and implement a palliative care policy acknowledging the Accreditation Standards and State legislation and including a simple tool for advance care planning. Case conferencing could assist in discussing and documenting the resident's wishes. Public education is essential to increase community and professional awareness in order to promote empowerment for the increasing number of older people who will die in residential aged care facilities.

Identification of patients with noncancer diseases for palliative care services.

OBJECTIVE: To identify criteria for measuring the eligibility of patients with end-stage noncancer diseases for palliative care services in Australian residential aged care facilities. METHODS: No validated set if guidelines were available so five instruments were used: an adaptation of the American National Hospice Association Guidelines; a recent adaptation of the Karnofsky Performance Scale; the Modified Barthel Index; the Abbey Pain Score for assessment of people who are nonverbal and a Verbal Descriptor Scale, also for pain measurement. In addition, nutritional status and the presence of other problematic symptoms and their severity were also sought. RESULTS: The adapted American National Hospice Association Guidelines provided an initial indicative framework and the other instruments were useful in providing confirmatory data for service eligibility and delivery.

Grief and bereavement.

Bereavement support is an integral part of palliative care. Grieving after loss is a normal process; however, some grief reactions become complicated and may seriously compromise the health of an individual. Routine bereavement care helps identify people at risk of complicated grieving. The burden of grief can last for years, sometimes indefinitely. People caring for the bereaved need to pay special attention to cultural differences, the burden of caring for dying children, and the special support needs of bereaved children and adolescents. Excellent resources to assist in grief management, including the expertise of palliative care teams, are readily available.

Issues in palliative care for Indigenous communities.

All Indigenous communities in Australia have a common heritage of loss. Indigenous death rates are much higher than those for white Australians. Indigenous people use healthcare services reluctantly, and palliative care services rarely. Cultural considerations that need to be respected include Indigenous understandings of disease causation, attributions of blame for sickness, the performance of ceremonies after death and the importance of dying on traditional lands. The involvement of Indigenous health workers in clinical care increases confidence in the healthcare system as a whole.

Palliative care education in the developing countries.

Individuals who have experience in palliative care in wealthier countries with well-structured health systems see the palliative care needs of developing countries as forbiddingly huge. They are aware of an increasing incidence of cancer, but health delivery systems are often patchy and deficient, medications for pain management are not widely available, and cultural considerations limit opportunities to face advanced illness and focus on symptom control in terminal illness. An increasing prevalence of HIV infection compounds palliative care needs. Medical practice focuses on interventions that promise cure and earn a good reward, while nursing standards are variable and often unsatisfactory. There is a need for demonstrations of good care and effective symptom control, even if these reach only a small fraction of the needy population. On such demonstrations can be built education programs that take account of local realities, and promote attitudes, knowledge and skills capable of gradually introducing a greater professional concern and a better prospect of effective care for the dying.

Issues in the conduct of therapeutic trials in palliative care: an Australian perspective.

Palliative care has been slow to demonstrate that its common interventions are supported by high levels of evidence. There are multiple reasons for this--historical and cultural, as well as the recognised difficulties of conducting studies in dying persons. There are problems in isolating the effect of a single intervention from the many other changing dimensions which attend the progress of terminal illness, and problems also in defining particular outcomes free from the contaminating effect of other simultaneous changes in a patient's situation. Sickness is an interaction between disease and patient, and science sits more comfortably with the study of disease than with the understanding of the patient. Nevertheless, the therapies commonly employed for symptom management in individuals with advanced and terminal illness deserve more rigorous investigation to establish their efficacy. In Australia, new levels of government support for research have stimulated a closer examination of principles and practical guidelines for the conduct of research in this area of healthcare.
