Legalizing physician-assisted suicide and/or euthanasia: Pragmatic implications

Objective: Despite the availability of palliative care in many countries, legalization of euthanasia and physician-assisted suicide (EAS) continues to be debated-particularly around ethical and legal issues-and the surrounding controversy shows no signs of abating. Responding to EAS requests is considered one of the most difficult healthcare responsibilities. In the present paper, we highlight some of the less frequently discussed practical implications for palliative care provision if EAS were to be legalized. Our aim was not to take an explicit anti-EAS stance or expand on findings from systematic reviews or philosophical and ethico-legal treatises, but rather to offer clinical perspectives and the potential pragmatic implications of legalized EAS for palliative care provision, patients and families, healthcare professionals, and the broader community.

Method: We provide insights from our multidisciplinary clinical experience, coupled with those from various jurisdictions where EAS is, or has been, legalized.

Results: We believe that these issues, many of which are encountered at the bedside, must be considered in detail so that the pragmatic implications of EAS can be comprehensively considered.

Significance of Results: Increased resources and effort must be directed toward training, research, community engagement, and ensuring adequate resourcing for palliative care before further consideration is given to allocating resources for legalizing euthanasia and physician-assisted suicide.

Philosophy and Political Engagement: Reflection in the Public Sphere

Do philosophers have a responsibility to their society that is distinct from their responsibility to it as citizens? This edited volume explores both what type of contribution philosophy can make and what type of reasoning is appropriate when addressing public matters now. These questions are posed by leading international scholars working in the fields of moral and political philosophy. Each contribution also investigates the central issue of how to combine critical, rational analysis with a commitment to politically relevant public engagement. The contributions to this volume analyse issues raised in practical ethics, including abortion, embryology, and assisted suicide. They consider the role of ethical commitment in the philosophical analysis of contemporary political issues, and engage with matters of public policy such as poverty, the arts, meaningful work, as well as the evidence base for policy. They also examine the normative legitimacy of power, including the use of violence.

Physician recommendation for invasive prenatal testing: the case of the 'precious baby'

Do clinicians manage pregnancies conceived by assisted reproductive technologies (ART) differently from spontaneous pregnancies?

Clinicians decisions about prenatal testing during pregnancy depend, at least partially, on the method of conception.

Research thus far has shown that patients decisions regarding prenatal screening are different in ART pregnancies compared with spontaneous ones, such that ART pregnancies may be considered more valuable or precious than pregnancies conceived without treatment.

In this cross-sectional study, preformed during the year 2011, 163 obstetricians and gynecologists in Israel completed an anonymous online questionnaire.

Clinicians were randomly assigned to read one of two versions of a vignette describing the case of a pregnant woman. The two versions differed only with regard to the method of conception (ART; n 78 versus spontaneous; n 85). Clinicians were asked to provide their recommendations regarding amniocentesis.

The response rate among all clinicians invited to complete the questionnaire was 16.7. Of the 85 clinicians presented with the spontaneous pregnancy scenario, 37 (43.5) recommended amniocentesis. In contrast, of the 78 clinicians presented with the ART pregnancy scenario, only 15 (19.2) recommended the test. Clinicians were 3.2 (95 confidence interval [CI]: 1.66.6) times more likely to recommend amniocentesis for a spontaneous pregnancy than for an ART pregnancy.

The study is limited by a low response rate, the relatively small sample and the hypothetical nature of the decision, as clinician recommendations may have differed in an actual clinical setting.

Our findings show that fertility history and use of ART may affect clinicians recommendations regarding amniocentesis following receipt of screening test results. This raises the question of how subjective factors influence clinicians decisions regarding other aspects of pregnancy management.

The Role of Tool/Sheet Contact in Plug-Assisted Thermoforming.

Plug-assisted thermoforming produces a wide range of polymer products through a combination of deformation by air pressure and contact with tool surfaces. In this paper the role of tool/sheet contact in determining the process output is investigated. A combination of thermoforming, friction and heat transfer tests were carried out on common tool and sheet materials. The results show that the typical friction coefficients for the material combinations are within the range 0.1 to 0.3, but the values rise sharply on approaching thermoforming temperatures. Thermal imaging tests demonstrate that all of the plug materials significantly cool the heated sheet on contact, even over very short periods of time. The temperature of the plug is very important. At low plug temperatures heat transfer effects predominate, whereas at high plug temperatures friction effects predominate. A plug temperature of approximately 100oC balances these effects and creates the most effective material distribution.

An algorithm to predict pregnancy in assisted conception

BACKGROUND: Male fertility potential cannot be measured by conventional parameters for assisted reproduction by intracytoplasmic sperm injection. This study determines the relationship between testicular and ejaculated sperm mitochondrial (mt) DNA deletions, nuclear (n) DNA fragmentation and fertilisation and pregnancy rates in ICSI. METHODS: Ejaculated sperm were obtained from 77 men and testicular sperm from 28 men with obstructive azoospermia undergoing ICSI. Testicular sperm were retrieved using a Trucut needle. MtDNA analysed using a long polymerase chain reaction. The alkaline Comet assay determined nDNA fragmentation. RESULTS: Of subjects who achieved a pregnancy (50%) using testicular sperm, only 26% had partners�??�?�¢?? sperm with wild type (WT) mtDNA. Of pregnant subjects (38%) using ejaculated sperm, only 8% had partner sperm with WT mtDNA.. In each, the successful group had less mtDNA deletions and less nDNA fragmentation. There were inverse relationships between pregnancy and mtDNA deletion numbers, size and nDNA fragmentation for both testicular and ejaculated sperm. No relationships were observed with fertilisation rates. An algorithm for the prediction of pregnancy is presented based on the quality of sperm nDNA and mtDNA. CONCLUSION: In both testicular and ejaculated sperm, mtDNA deletions and nDNA fragmentation are closely associated with pregnancy in ICSI.
