Intention, foresight and ending life : a response to "The Double Effect effect" by Charles Foster, Jonathan Herring, Karen Melham and Tony Hope, (CQ 20(1))

In this paper I examine the recent arguments by Charles Foster, Jonathan Herring, Karen Melham and Tony Hope against the utility of the doctrine of double effect. One basis on which they reject the utility of the doctrine is their claim that it is notoriously difficult to apply what they identify as its 'core' component, namely, the distinction between intention and foresight. It is this contention that is the primarily focus of my article. I argue against this claim that the intention/foresight distinction remains a fundamental part of the law in those jurisdictions where intention remains an element of the offence of murder and that, accordingly, it is essential ro resolve the putative difficulties of applying the intention/foresight distinction so as to ensure the integrity of the law of murder. I argue that the main reasons advanced for the claim that the intention/foresight distinction is difficult to apply are ultimately unsustainable, and that the distinction is not as difficult to apply as the authors suggest.

Palliative care, double effect and the law in Australia

Care and decision-making at the end of life that promotes comfort and dignity is widely endorsed by public policy and the law. In ethical analysis of palliative care interventions that are argued potentially to hasten death, these may be deemed to be ethically permissible by the application of the doctrine of double effect, if the doctor’s intention is to relieve pain and not cause death. In part because of the significance of ethics in the development of law in the medical sphere, this doctrine is also likely to be recognized as part of Australia’s common law, although hitherto there have been no cases concerning palliative care brought before a court in Australia to test this. Three Australian States have, nonetheless, created legislative defences that are different from the common law with the intent of clarifying the law, promoting palliative care, and distinguishing it from euthanasia. However, these defences have the potential to provide less protection for doctors administering palliative care. In addition to requiring a doctor to have an appropriate intent, the defences insist on adherence to particular medical practice standards and perhaps require patient consent. Doctors providing end-of-life care in these States need to be aware of these legislative changes. Acting in accordance with the common law doctrine of double effect may not provide legal protection. Similar changes are likely to occur in other States and Territories as there is a trend towards enacting legislative defences that deal with the provision of palliative care.

(Dia)logics of difference disability, performance and spectatorship in Liz Crow's Resistance on the Plinth

In this article I examine how artists with disabilities use public-space performance to encourage passersby to reflect on the construction of public discourses about disability – and, therefore, the construction of publics that are potentially inclusive of people with disabilities. I concentrate on British storyteller, artist, filmmaker and activist Liz Crow's Resistance on the Plinth, one of four pieces Crow has produced over the past three years as part of the Resistance series, an examination of the Nazi regime's Aktion T4 programme, which resulted in the mass murder of a quarter of a million people with disabilities. Created in August 2009 as part of Antony Gormley's One & Other public art project, the piece featured Crow dressed in a Nazi uniform and seated in a wheelchair on the Fourth Plinth in London's Trafalgar Square. For Crow – who creates work in a British context where public debate about the eugenics of genetic testing, euthanasia and assisted suicide is prevalent in the media – the Nazi atrocity is still rich in confronting imagery, resonant and relevant in a contemporary context. In this article, I consider the challenges that Gormley's extremely public One & Other presented for professional artists like Crow, who are committed to intervening in public perceptions of identity, community and culture. I describe the structural choices Crow made to provoke debate about the cultural logics embodied in the image she presented, and analyse some of the spectatorial responses from online forums such as the One & Other website, Facebook and Twitter immediately following the event.

Prosecutorial discretion in assisted dying in Canada : a proposal for charging guidelines

An Expert Panel of the Royal Society of Canada and a Select Committee of the Québec National Assembly both recently recommended the issuance of permissive guidelines for the exercise of prosecutorial discretion on voluntary euthanasia and assisted suicide and “medical aid in dying” respectively. It seems timely, therefore, to propose a set of offence-specific guidelines for how prosecutorial discretion should be exercised in cases of voluntary euthanasia and assisted suicide in Canadian provinces and territories. We take as our starting point the only existing guidelines of this sort currently in force in the world (i.e. the British Columbia Guidelines, and the England and Wales Guidelines). In light of certain concerns we have with these guidelines, we outline an approach to constructing guidelines for Canadian jurisdictions that begins with identifying three guiding principles we argue are appropriate for this purpose (respect for autonomy, the need for high-quality prosecutorial decision making, and the importance of public confidence in that decision making), and ends with a concrete and detailed set of proposed guidelines. The paper is consistent with, but also extends, the work of the Royal Society of Canada Expert Panel on End of Life Decision Making. Un panel d’expert de la Société Royale du Canada et une Commission spéciale de l’Assemblée nationale du Québec ont tous les deux récemment recommandé que soit émises des directives permettant exercice d’un pouvoir de poursuite discrétionnaire concernant l’euthanasie et le suicide assisté et « l’assistance médicale pour mourir », respectivement. Il semble donc à propos de proposer une série de directives spécifiques aux offenses sur la façon dont le pouvoir de poursuite discrétionnaire dans les territoires et provinces canadiennes serait appliqué dans les cas d’euthanasie et de suicide assisté. Nous avons pris comme point de départ les seules directives de la sorte existant déjà (c’est-à-dire celle de la Colombie-Britannique et de l’Angleterre et du Pays de Galles). Par contre, compte tenu de certaines de nos réserves concernant ces directives, nous avons ensuite établi les grandes lignes d’une approche permettant de mettre sur pied des directives pour les juridictions canadiennes, qui débute par l’identification de trois principes de base qui sont selon nous appropriées à cette fin (respect de l’autonomie, besoin pour une grande qualité de prise de prise de décision du poursuivant et la confiance du public envers cette prise de décision) pour se terminer par une série de directives concrètes et détaillées. Le présent document est compatible avec le travail de la Société royale du Canada tout en en augmentant la portée.

Assisting a suicide : potential succession law consequences

The recent criminal law decisions where people have been convicted of aiding suicide raise important legal and ethical issues in relation to whether euthanasia should be legalised. These cases also raise issues of great significance for succession lawyers. Where, as in cases such as Nielsen and Justins, the person convicted of aiding a suicide is a principal beneficiary under the will of the deceased, various legal consequences, such as: forfeiture of the interest under the will; liability for breach of fiduciary obligation; and/or a finding of undue influence, may follow which may result in loss of such benefit.

The right to choose an assisted death : time for legislation?

The legal framework that operates at the end of life in Australia needs to be reformed. • Voluntary euthanasia and assisted suicide are currently unlawful. • Both activities nevertheless occur not infrequently in Australia, in part because palliative care cannot relieve physical and psychological pain and suffering in all cases. • In this respect, the law is deficient. The law is also unfair because it doesn’t treat people equally. Some people can be helped to die on their own terms as a result of their knowledge and/or connections while some are able to hasten their death by the refusal of life-sustaining treatment. But others do not have access to the means for their life to end. • A very substantial majority of Australians have repeatedly expressed in public opinion polls their desire for law reform on these matters. Many are concerned at what they see is happening to their loved ones as they reach the end of their lives, and want the confidence that when their time comes they will be able to exercise choice in relation to assisted dying. • The most consistent reason advanced not to change the law is the need to protect the vulnerable. There is a concern that if the law allows voluntary euthanasia and assisted suicide for some people, it will be expanded and abused, including pressures being placed on highly dependent people and those with disabilities to agree to euthanasia. • But there is now a large body of experience in a number of international jurisdictions following the legalisation of voluntary euthanasia and/or assisted suicide. This shows that appropriate safeguards can be implemented to protect vulnerable people and prevent the abuse that opponents of assisted dying have feared. It reveals that assisted dying meets a real need among a small minority of people at the end of their lives. It also provides reassurance to people with terminal and incurable disease that they will not be left to suffer the indignities and discomfort of a nasty death. • Australia is an increasingly secular society. Strong opposition to assisted death by religious groups that is based on their belief in divine sanctity of all human life is not a justification for denying choice for those who do not share that belief. • It is now time for Australian legislators to respond to this concern and this experience by legislating to enhance the quality of death for those Australians who seek assisted dying.

Histopathological examination of chronic laminitis in Kaimanawa feral horses of New Zealand

AIMS: To investigate the prevalence, histopathological and histomorphometric presentation of chronic laminitis in a population of Kaimanawa feral horses. METHODS: Following the capture and euthanasia of feral horses from the Kaimanawa Ranges of New Zealand, the left forefoot of 28 stallions and 28 mares aged between 6 and 12 years were removed and processed for histology. Sections of lamellar samples from each horse were examined using light microscopy. The presence of laminitis was assessed and the histopathological lesions were described. Horses were grouped by histological diagnosis into laminitic and non-laminitic groups and histomorphometric analysis was conducted and compared between groups. The parameters examined were total length of primary epidermal lamellae (PEL), keratinised length of PEL, and the length of secondary epidermal lamellae (SEL) at the abaxial end and axial end of each PEL. RESULTS: Of the horses examined, 25 (45%) were diagnosed with chronic laminitis. The most prevalent histopathological features were the presence of excessive cap horn, and multi-branched and attenuated SEL. Histomorphometric assessment of the lamellar architecture revealed no difference in morphometric measurements between the normal and laminitic groups for any parameter measured (p>0.05). CONCLUSIONS: The current study found a high prevalence of laminitis in feral Kaimanawa horses. The reason for this in the Kaimanawa population is not known. Histomorphometric analysis may not be a good indicator of chronic laminitis in feral horses. CLINICAL RELEVANCE: It is an important finding that the feral horse lifestyle in the environment of the Kaimanawa Ranges in New Zealand offers no protection against foot disease. The finding suggests that horses are vulnerable to laminitis whether in domestic care or in a feral habitat.

Does withdrawing life-sustaining treatment cause death or allow the patient to die?

The paper discusses the view of Franklin Miller and Robert Truog that withdrawing life-sustaining treatment causes death and so is a form of killing. I reject that view. I argue that even if we think there is no morally relevant difference between allowing a patient to die and killing her (itself a controversial view), it does not follow that allowing to die is a form of killing. I then argue that withdrawing life-sustaining treatment is properly classified as allowing the patient to die rather than as killing her. Once this is accepted, the law cannot be criticised for inconsistency by holding, as it does, that it is lawful to withdraw life-sustaining treatment but unlawful to give patients a lethal injection.

Voluntary palliated starvation : A lawful and ethical way to die?

Increasingly, individuals want control over their own destiny. This includes the way in which they die and the timing of their death. The desire for self-determination at the end of life is one of the drivers for the ever-increasing number of jurisdictions overseas that are legalising voluntary euthanasia and/or assisted suicide, and for the continuous attempts to reform state and territory law in Australia. Despite public support for law reform in this field, legislative change in Australia is unlikely in the near future given the current political landscape. We argue that there may be another solution which provides competent adults with control over their death and to have any pain and symptoms managed by doctors, but which is currently lawful and consistent with prevailing ethical principles. ‘Voluntary palliated starvation’ refers to the process which occurs when a competent individual chooses to stop eating and drinking, and receives palliative care to address pain, suffering and symptoms that may be experienced by the individual as he or she approaches death. In this article, we argue that, at least in some circumstances, such a death would be lawful for the individual and doctors involved, and consistent with principles of medical ethics.

Defensa de la vida física del paciente en estado terminal : entre la dignidad y la autonomía

Resumen: Proponemos un análisis crítico de los fundamentos que sustentan la llamada “Ley de Muerte Digna” incorporada en la Ley que consagra la regulación de los derechos del paciente, historia clínica, consentimiento informado, (Art. 2º, inc. “e” párr. 2º de la Ley 26.529 modificada por la Ley 26.742), que introduce en nuestro país la existencia real de un sistema eutanásico formal sin fundamentos de orden científico, éticos e incluso jurídicos. ¿Es moralmente lícito suprimir la vida del enfermo terminal?, ¿la legalización de esta práctica eutanásica es la primera piedra de una nueva “cultura” de la vida? Entendemos que la llamada “tesis de la autonomía”, fundante de la reforma legislativa en cuestión, desde una óptica Bioética personalista, merece serias objeciones bioéticas ya que puede distorsionar gravemente el ejercicio de la medicina y la relación médico paciente.

Los derechos y deberes de médicos y pacientes desde la vigencia de la Ley 26.529

Resumen: El artículo considera los derechos y deberes de médicos y pacientes, especialmente luego de la sanción de la ley 26.529, destacando sus temas relevantes, aquellos que habían dado lugar a distintas interpretaciones tanto en la jurisprudencia, como en la doctrina. Se tratan, así, la historia clínica y el consentimiento informado, precisándose sus conceptos, formas, funciones e interpretaciones. Similar atención merecen las directivas anticipadas de salud, el “testamento vital”, las posibilidades del médico y sus posibles objeciones de conciencia. De igual modo la autonomía de la voluntad del paciente, su libertad y responsabilidad. Se considera la eutanasia, precisándose que no es un derecho del paciente. Se estudia el secreto profesional del médico, a la luz de las contradictorias normas legales vigentes y jurisprudencia consecuente, para detenerse en la más reciente decisión de la Corte Suprema de Justicia de la Nación en su actual composición. Finalmente se precisan los conceptos de las responsabilidades de médicos y órganos sanitarios, con la posibilidad de su aseguramiento y el conflicto de algunas de las coberturas que se otorgan en plaza, como la conocida claims made.

Efeitos de dois regimes de aplicação de clodronato dissódico na reabsorção radicular e movimentação dentária em Rattus norvegicus

O objetivo dos autores foi avaliar microscopicamente, a influência de dois regimes de aplicação do clodronato dissódico na movimentação dentária e reabsorção radicular de Rattus novergicus. Foram utilizados 63 ratos, adultos, machos, com dentição permanente completa e peso aproximado de 300g. Os animais foram divididos em três grupos com 21 espécimes cada: Grupo Controle, animais submetidos à movimentação dentária induzida sem aplicação do medicamento; Grupo A, animais submetidos à movimentação com aplicação do Clodronato por via subcutânea em dias alternados; Grupo B, animais submetidos à movimentação e aplicação da droga por via subcutânea apenas no quinto e décimo segundo dias. Para avaliar os eventos celulares que ocorrem durante todo o ciclo de movimentação, os grupos foram subdivididos em três, com sete animais cada um e foi realizada a eutanásia no sétimo, décimo e décimo quarto dias. Este procedimento foi realizado com anestesia por inalação de dietil-éter e administração intra-abdominal de 40mg/Kg de pentobarbital sódico. As peças foram incluídas em parafina e os cortes teciduais (4-6m), corados por Hematoxilina-Eosina, foram usados para observações gerais e avaliação quantitativa em microscópio de luz. A análise dos resultados foi feita utilizando análise de variância (ANOVA) e o teste de Tukey foi utilizado para comparações múltiplas entre as médias. Foi considerado o nível de significância em 5%. A taxa de movimentação foi menor no Grupo A quando comparado ao grupo controle sendo estatisticamente significante (p< 0,01). No Grupo B, a taxa de movimentação foi menor que no grupo controle e maior que no Grupo A, porém sem significância estatística. Para as variáveis lacunas de reabsorção e número de osteoclastos houve diferença estatisticamente significativa quando o grupo controle foi comparado aos dois outros grupos. De acordo com os resultados, o Clodronato reduz a reabsorção radicular e a movimentação dentária, mas este último aspecto pode ser minimizado a depender do regime de aplicação do medicamento.

Efeitos da suplementação com diferentes óleos comestíveis durante o reparo tecidual cutâneo

Ácidos graxos são moléculas bioativas endógenas e exógenas, que podem ser potentes mediadores e/ou reguladores de muitos processos celulares, no entanto, os seus efeitos no reparo de lesões cutâneas não estão bem esclarecidos. O objetivo deste trabalho foi investigar os efeitos da suplementação com diferentes óleos comestíveis na cicatrização de lesões cutâneas. Para isso, ratos Wistar machos (6-8 semanas/ 150200g) foram separados em quatro grupos: Um grupo controle (n=7) e três grupos experimentais (n=21). Trinta dias antes de realizarmos a lesão no dorso de cada animal, demos início a suplementação diária pelo método de gavagem com 1,5ml/kg de óleo de girassol, linhaça ou peixe e esta se manteve até o dia da eutanásia (d14). Em d0 uma lesão excional (1cm) foi realizada na parte dorsal de cada animal. A contração da lesão e re-epitelização foram medidas em d0, d7 e d14. Ao sacrificarmos os animais a lesão foi coletada juntamente com pele normal adjacente. O fechamento da lesão foi significativamente maior no grupo de controle (área lesada 582%) em d7, quando comparado com os outros grupos (grupo girassol 682%, linhaça 772% e peixe 732%) com p<0,05, para todos. Em d14 observamos menor área lesada no grupo controle (área lesada 211%) em relação aos grupos suplementados com óleo de linhaça e peixe (área lesada dos grupos linhaça 271% e peixe 271%), com p<0,05 para ambos os grupos. Não observamos diferença no fechamento da lesão quando comparamos os grupos controle (área lesada 211%) e girassol (área lesada 251%). Em relação ao infiltrado inflamatório observamos uma quantidade moderada nos grupos controle, linhaça e peixe, enquanto que no grupo girassol foram encontradas poucas células inflamatórias. Grande número de miofibroblastos foi observado nos grupos controle e girassol na região superficial do tecido de granulação. Entretanto, nos grupos linhaça e peixe observamos poucos miofibroblastos e muitos vasos sanguíneos dilatados. Os grupos controle e girassol apresentaram vasos sanguíneos ocluídos e concentrados na região profunda do tecido de granulação. Os grupos controle e girassol apresentaram densidade moderada de fibras colágenas na região profunda do tecido de granulação. Esse resultado foi confirmado através da dosagem de hidroxiprolina. Os níveis de hidroxiprolina estavam menores nos grupos controle e girassol quando comparados com os grupos linhaça e peixe. A suplementação com diferentes tipos de óleos comestíveis retarda o processo de contração da lesão e afeta o infiltrado inflamatório e a deposição de fibras colágenas

Dieta hiperlipídica materna e pós-natal promove remodelamento adverso do fígado, pâncreas e tecido adiposo na prole

A dieta hiperlipídica (high-fat, HF) materna durante a gestação e/ou lactação aumenta a susceptibilidade da prole para o desenvolvimento de doenças crônicas na fase adulta. Verificar a hipótese que a ingestão materna de dieta HF nos períodos críticos de desenvolvimento (gestação e/ou lactação) predispõe à doença não alcoólica do fígado gorduroso e alterações pancreáticas e no tecido adiposo de camundongos machos adultos. Camundongos C57BL/6 fêmeas receberam durante a gestação e/ou lactação dieta padrão (standard chow, SC) ou HF. Filhotes machos foram divididos em cinco grupos: SC provenientes de mães SC; G provenientes de mães HF durante a gestação; L provenientes de mães HF durante a lactação; GL/HF provenientes de mães HF durante a gestação/lactação, mantendo a mesma dieta HF no período pós-natal (do desmame aos 3 meses deidade); GL provenientes de mães HF durante a gestação/lactação trocando a dieta para SC no período pós-natal (do desmame aos 3 meses deidade). Foi analisada ao longo do experimento a massa corporal da prole. No sacrifício (3 meses), o fígado, o pâncreas e a gordura epididimária foram removidos, pesados e processados e o sangue foi coletado para análise bioquímica. Ao nascimento e ao desmame, filhotes GL/HF foram mais pesados (+6% e +44%, p<0,05, respectivamente) que os filhotes SC. Os filhotes G apresentaram resistência à insulina e menor expressão do transportador de glicose no fígado (GLUT-2). A esteatose hepática foi observada nos grupos G, L, GL e principalmente nos filhotes do grupo GL/HF. A expressão hepática da proteína ligante de elementos regulatórios de esteróis (SREBP-1c) estava aumentada nos filhotes G, GL e GL/HF. Os filhotes G, GL e GL/HF apresentaram hipertrofia da ilhota pancreática e dos adipócitos quando comparados com o grupo SC. O consumo de dieta HF durante a gestação mostra-se ser o período mais prejudicial para os filhotes adultos de camundongos. A programação metabólica por dieta HF leva ao remodelamento adverso do fígado, do pâncreas e do tecido adiposo
