Formulating MEDLINE queries for article retrieval based on PubMed exemplars

Bibliographic search engines allow endless possibilities for building queries based on specific words or phrases in article titles and abstracts, indexing terms, and other attributes. Unfortunately, deciding which attributes to use in a methodologically sound query is a non-trivial process. In this paper, we describe a system to help with this task, given an example set of PubMed articles to retrieve and a corresponding set of articles to exclude. The system provides the users with unigram and bigram features from the title, abstract, MeSH terms, and MeSH qualifier terms in decreasing order of precision, given a recall threshold. From this information and their knowledge of the domain, users can formulate a query and evaluate its performance. We apply the system to the task of distinguishing original research articles of functional magnetic resonance imaging (fMRI) of sensorimotor function from fMRI studies of higher cognitive functions

Reducing Barriers to Ethics in Neuroscience

Ethics is a growing interest for neuroscientists, but rather than signifying a commitment to the protection of human subjects, care of animals, and public understanding to which the professional community is engaged in a fundamental way, interest has been consumed by administrative overhead and the mission creep of institutional ethics reviews. Faculty, trainees, and staff (n = 605) in North America whose work involves brain imaging and brain stimulation completed an online survey about ethics in their research. Using factor analysis and linear regression, we found significant effects for invasiveness of imaging technique, professional position, gender, and local presence of bioethics centers. We propose strategies for improving communication between the neuroscience community and ethics review boards, collaborations between neuroscientists and biomedical ethicists, and ethics training in graduate neuroscience programs to revitalize mutual goals and interests

Navigating Physicians’ Ethical and Legal Duties to Patients Seeking Unproven Interventions Abroad

Medical tourism (MT), the practice of traveling to another country to access medical care that is paid for out of pocket, has received considerable attention in the Canadian news media.Media and industry information sources, which are commonly accessed by medical tourists, might inadequately inform Canadians about MT safety concerns. As a result, there is concern among Canadian physicians and health and safety professionals that prospective medical tourists might not be well placed to make informed decisions about their care. As gatekeepers in the health care system and the first source of interaction between the health care system and patients, family physicians are well positioned to inform Canadians about these safety risks

Neurocognitive Enhancement: what can we do and what should we do?

Our growing ability to alter brain function can be used to enhance the mental processes of normal individuals as well as to treat mental dysfunction in people who are ill. The prospect of neurocognitive enhancement raises many issues about what is safe, fair and otherwise morally acceptable. This article resulted from a meeting on neurocognitive enhancement that was held by the authors. Our goal is to review the state of the art in neurocognitive enhancement, its attendant social and ethical problems, and the ways in which society can address these problems

Neuroethics and fMRI: Mapping a Fledgling Relationship

Human functional magnetic resonance imaging (fMRI) informs the understanding of the neural basis of mental function and is a key domain of ethical enquiry. It raises questions about the practice and implications of research, and reflexively informs ethics through the empirical investigation of moral judgments. It is at the centre of debate surrounding the importance of neuroscience findings for concepts such as personhood and free will, and the extent of their practical consequences. Here, we map the landscape of fMRI and neuroethics, using citation analysis to uncover salient topics. We find that this landscape is sparsely populated: despite previous calls for debate, there are few articles that discuss both fMRI and ethical, legal, or social implications (ELSI), and even fewer direct citations between the two literatures. Recognizing that practical barriers exist to integrating ELSI discussion into the research literature, we argue nonetheless that the ethical challenges of fMRI, and controversy over its conceptual and practical implications, make this essential

The Stem Cell Research Environment:A Patchwork of Patchworks

Few areas of recent research have received as much focus or generated as much excitement and debate as stem cell research. Hope for the therapeutic promise of this field has been matched by social concern associated largely with the sources of stem cells and their uses. This interplay between promise and controversy has contributed to the enormous variation that exists among the environments in which stem cell research is conducted throughout the world. This variation is layered upon intra-jurisdictional policies that are also often complex and in flux, resulting in what we term a 'patchwork of patchworks'. This patchwork of patchworks and its implications will become increasingly important as we enter this new era of stem cell research. The current progression towards translational and clinical research among international collaborators serves as a catalyst for identifying potential policy conflict and makes it imperative to address jurisdictional variability in stem cell research environments. The existing patchworks seen in contemporary stem cell research environments provide a valuable opportunity to consider how variations in regulations and policies across and within jurisdictions influence research efficiencies and directions. In one sense, the stem cell research context can be viewed as a living experiment occurring across the globe. The lessons to be gleaned from examining this field have great potential for broad-ranging general science policy application

Trapped inside your head : An ethics journey in modern biomedicine for the brain

Dr. Illes’ research, teaching and outreach initiatives are devoted to ethical, legal, social and policy challenges at the intersection of the brain sciences and biomedical ethics. She writes frequently for the Vancouver Sun and The Conversation Canada, and hosts community outreach activities covering challenging ethical problems related to biomedicine and the brain. Dr. Illes is also co-lead of the Canadian Brain Research Strategy of the International Brain Initiative, and sits on numerous advisory boards, including as Vice Chair of the Institute for Neuroscience Mental Health and Addiction of the Canadian Institutes of Health Research. She is a Director-at-Large of the Canadian Academy of Health Sciences, a fellow of the Royal Society of Canada and the American Association for the Advancement of Science, and a member of the International Women’s Forum. Her latest books, a series on Developments in Neuroethics and Bioethics, feature pain, global mental health, do-it-yourself brain devices, neurolaw, and neuroarchitecture.Medicine, Faculty ofMedicine, Department ofNeurology, Division ofUnreviewedFacult
