REVIEW
Sonya Levine, Laura Grabel
Chimeric animals are made up of cells from two separate zygotes. Human/non-human animal chimeras have been used for a number of research purposes, including human disease modeling. Pluripotent stem cell (PSC) research has relied upon the chimera approach to examine the developmental potential of stem cells, to determine the efficacy of cell replacement therapies, and to establish a means of producing human organs. Based on ethical issues, this work has faced pushback from various sources including funding agencies...

STUDY QUESTION: Do women who place high importance on career success have different perceptions of pregnancy planning, delayed reproduction, and the ethical acceptability of ART than women with less emphasis on their career? SUMMARY ANSWER: Career-focused women place more importance on pregnancy planning, have greater confidence in delayed childbearing, and are more ethically accepting of donor gamete ART than women who do not place as much importance on career success...

STUDY QUESTION: Does progesterone in human follicular fluid (hFF) activate CatSper and do other components of hFF modulate this effect and/or contribute separately to hFF-induced Ca2+ signaling? SUMMARY ANSWER: hFF potently stimulates CatSper and increases [Ca2+]i, primarily due to high concentrations of progesterone, however, other components of hFF also contribute to [Ca2+]i signaling, including modulation of CatSper channel activity and inhibition of [Ca2+]i oscillations...

OBJECTIVES: End-of-life decisions are not only common in the ICU but also frequently elicit strong feelings among health professionals. Even though we seek to develop more collegial interprofessional approaches to care and health decision-making, there are many barriers to successfully managing complex decisions. The aim of this study is to better understand how emotions influence the end-of-life decision-making process among professionals working in ICU. DESIGN: Qualitative study with clinical interviews...

Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth...

Point-of-care ultrasound imaging is increasingly used by anesthesiologists to facilitate rapid clinical diagnosis and treatment in the perioperative period. With its growing popularity, inevitably, unfamiliar structures will be observed. We present a case of cystic liver lesions in a healthy model during a point-of-care workshop. We address the clinical, ethical, and legal implications of incidental findings in anesthesiology. We offer recommendations and an algorithmic approach to these occurrences.

Karola V Kreitmair, Katherine E Kruse
This article addresses questions surrounding the minimally conscious state (MCS) from the perspective of adult clinical ethics. It describes the background of the MCS diagnosis, analyzes phenomenological ambiguities inherent in the nature of MCS, and raises epistemological concerns surrounding its diagnosis. It argues that in many cases, the burdens of prolonging treatment for people who have sustained certain severe brain injuries (SBI) outweigh the benefits, even if they are in or have the prospect of entering into MCS...

Severe head injury or brain injury presents clinical neuroscientists with a unique challenge. Based on an objective assessment of cognitive and neurological function, it is sometimes hard to recognize our patients as members of our moral community (actually or potentially) but we treat them as if that were is the case, and, therefore, as if they need rescuing. Thus their existences as enigmata-beings who may or may not reveal themselves to us through social and personal function realized in conversations and relationships-are in doubt...

Suppose that a colleague proposed a fantastic experiment: to introduce human stem cells into a neonatal mouse so that its entire brain developed into "human-like" neuronal structures. The colleague claimed it would still be a mouse, and that its chimeric brain would be nothing like a "human" one. It would not, as a result, have a moral status beyond its nonhuman animal origins. Thus, the "human neuron mouse" would allow scientists to tinker with human-like neurology in ways that would be precluded if it were a human being, and that would promise to lead to substantial understanding of the destructive and incurable brain diseases that befall humanity...

There is growing evidence about the influence of chemical exposures on specific molecular systems and mechanisms involved in cognitive and mental function. Evidence is also emerging about the negative impact of these chemical exposures on mental health, including depression, suicide, and other risks. Despite the growing appreciation of these factors, however, little attention has been paid to the ethical and social implications of their interactions. Drawing on recent work that argues for an environmental neuroethics approach that explicitly brings together ethics, environment, and conditions of the central nervous system, this article focuses on these critical issues for pesticides specifically...

Diagnostic classification systems in psychiatry have continued to rely on clinical phenomenology, despite limitations inherent in that approach. In view of these limitations and recent progress in neuroscience, the National Institute of Mental Health (NIMH) has initiated the Research Domain Criteria (RDoC) project to develop a more neuroscientifically based system of characterizing and classifying psychiatric disorders. The RDoC initiative aims to transform psychiatry into an integrative science of psychopathology in which mental illnesses will be defined as involving putative dysfunctions in neural nodes and networks...

Brain-computer interfaces (BCIs) can enable communication for persons in severe paralysis including locked-in syndrome (LIS); that is, being unable to move or speak while aware. In cases of complete loss of muscle control, termed "complete locked-in syndrome," a BCI may be the only viable solution to restore communication. However, a widespread ignorance regarding quality of life in LIS, current BCIs, and their potential as an assistive technology for persons in LIS, needlessly causes a harmful situation for this cohort...

Philipp Kellmeyer
Currently, many scientific fields such as psychology or biomedicine face a methodological crisis concerning the reproducibility, replicability, and validity of their research. In neuroimaging, similar methodological concerns have taken hold of the field, and researchers are working frantically toward finding solutions for the methodological problems specific to neuroimaging. This article examines some ethical and legal implications of this methodological crisis in neuroimaging. With respect to ethical challenges, the article discusses the impact of flawed methods in neuroimaging research in cognitive and clinical neuroscience, particularly with respect to faulty brain-based models of human cognition, behavior, and personality...

H S Wassif, L D'Cruz
This paper reflects on an educational development, a dental law and ethics course, as the course approaches its fifth anniversary. The authors outline their personal journey into developing and delivering this course, as well as sharing their best practice in relation to teaching dental postgraduate students who may approach the subject in different ways. It also highlights the vision behind this provision and how it is received by dental practitioners. The paper shares the learners' perception of topics such as ethics in comparison to law, and it highlights the perspective of both authors in teaching and following the students' journey in this course...

In the present study, we used the phenomenological approach to rediscover the ontological meaning of relationships with the deceased in Taiwanese widows/widowers. We first revised the original Western definitions of grief, bereavement, and mourning to fit Taiwanese culture. We used the word bei dao to indicate the mixed nature of grief and mourning in the Taiwanese bereavement process. Then we reanalyzed data from a previous study, which was conducted in 2006. In the previous qualitative research, each subject was interviewed 3 to 4 times in the mourning state over an 18-month interval that began at the point of the spouse's death...
