Over the past several decades, medical ethics has gained a solid foothold in medical education and is now a required course in most medical schools. Although the field of medical ethics is by nature eclectic, moral philosophy has played a dominant role in defining both the content of what is taught and the methodology for reasoning about ethical dilemmas. Most educators largely rely on the case‐based method for teaching ethics, grounding the ethical reasoning in an amalgam of theories drawn from (...) moral philosophy, including consequentialism, deontology, and principlism.In this article we hope to make a case for augmenting the focus of education in medical ethics. We propose complementing the traditional approach to medical ethics with a more embedded approach, one that has been described by others as “microethics,” the ethics of everyday clinical practice.

This article addresses whether cardiopulmonary resuscitation and sustained physiological support should ever be permitted in individuals who are diagnosed as brain dead and who had held previously expressed moral or religious objections to the currently accepted criteria for such a determination. It contrasts how requests for care would normally be treated in cases involving a brain-dead individual with previously expressed wishes to donate and a similarly diagnosed individual with previously expressed beliefs that did not conform to a brain-based conception of (...) death. The paper first focuses narrowly on requests for CPR and then expands its scope to address extended physiological support. It describes how refusing the brain-dead non-donor's requests for either CPR or extended support would represent enduring harm to the antemortem or previously autonomous individual by negating their beliefs and self-identity. The paper subsequently discusses potential implications of policy that would allow greater accommodations to those with conscientious objections to currently accepted brain-based death criteria, such as for cost, insurance, higher brain formulations and bedside communication. The conclusion is that granting wider latitude to personal conceptions around the definition of death, rather than forcing a contested definition on those with valid moral and religious objections, would benefit both individuals and society.

Background To determine whether fetal care paediatric and maternal–fetal medicine specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care.Methods Mail survey of 434 MFM and FCP specialists .Results MFMs were more likely than FCPs to disagree with these statements : ‘the (...) presence of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination’ ; ‘the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination’ ; and ‘the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination’ . 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being . Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes.Conclusions Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

Background While prenatal surgery historically was performed exclusively for lethal conditions, today intrauterine surgery is also performed to decrease postnatal disabilities for non-lethal conditions. We sought to describe physicians' attitudes about prenatal surgery for lethal and non-lethal conditions and to elucidate characteristics associated with these attitudes. Methods Survey of 1200 paediatric surgeons, neonatologists and maternal–fetal medicine specialists. Results Of 1176 eligible physicians, 670 responded. In the setting of a lethal condition for which prenatal surgery would likely result in the child (...) surviving with a severe disability, most respondents either disagreed or strongly disagreed that they would recommend the surgery. Male physicians were twice as likely to recommend surgery for the lethal condition, as were physicians who believe that abortion is morally wrong. Older physicians were less likely to recommend surgery. For non-lethal conditions, most respondents agreed that they would recommend prenatal surgery, even if the surgery increases the risk of prematurity or fetal death. Compared with MFMs, surgeons were less likely to recommend such surgery, as were physicians not affiliated with a fetal centre, and physicians who were religious. Conclusion Physician’s attitudes about prenatal surgery relate to physicians’ beliefs about disability as well as demographic, cultural and religious characteristics. Given the variety of views, parents are likely to receive different recommendations from their doctors about the preferable treatment choice. (shrink)

Field-Programmable Gate Arrays (FPGAs) have emerged as an attractive means of implementing logic circuits, providing instant manufacturing turnaround and negligible prototype costs. They hold the promise of replacing much of the VLSI market now held by mask-programmed gate arrays. FPGAs offer an affordable solution for customized VLSI, over a wide variety of applications, and have also opened up new possibilities in designing reconfigurable digital systems. Field-Programmable Gate Arrays discusses the most important aspects of FPGAs in a textbook manner. It provides (...) the reader with a focused view of the key issues, using a consistent notation and style of presentation. It provides detailed descriptions of commercially available FPGAs and an in-depth treatment of the FPGA architecture and CAD issues that are the subjects of current research. The material presented is of interest to a variety of readers, including those who are not familiar with FPGA technology, but wish to be introduced to it, as well as those who already have an understanding of FPGAs, but who are interested in learning about the research directions that are of current interest.

In the outpatient ultrasound suite of a major urban medical center, the mood is somber. A young woman lies tense and anxious. Pregnant for the first time, she has experienced early first-trimester bleeding. The radiologist relates the ultrasound findings: there has been a small hemorrhage, but there is a six-week-size fetus with normal cardiac activity. Translation: the baby is alive! The woman quietly sobs, happy but apprehensive.Across the drive, in the main hospital building, a young boy lies unresponsively comatose in (...) the Pediatric Intensive Care Unit. He was hit by a car while riding his bicycle. He is relying on a ventilator to breath, but his cardiovascular system is supporting itself. After a series... (shrink)
