Review of "Biomedical Informatics; Computer Applications in Health Care and Biomedicine" by Edward H. Shortliffe and James J. Cimino

This article is an invited review of the third edition of "Biomedical Informatics; Computer Applications in Health Care and Biomedicine", one of thirty-six volumes in Springer's 'Health Informatics Series', edited by E. Shortliffe and J. Cimino. This book spans most of the current methods and issues in health informatics, ranging through subjects as varied as data acquisition and storage, standards, natural language processing, imaging, electronic health records, decision support, teaching methods and ethics. The book is aimed at 'healthcare professionals', and is certainly appropriate for the non-technical informatics user. However, this book is also excellent background reading for the technical engineer who may be interested in the possible problems that confront the users in this field.     

Comparison of effects of a self management booklet and audiocassette for patients with asthma.

The effects on self management of asthma of a specially prepared book and audiocassette tape with similar contents were observed in a controlled study of 177 patients with asthma in general practice. After a run in period of six months patients were randomly given the book, the tape, both the book and tape, or neither. Patients'' knowledge of the use of drugs, perceptions of their disability, skill in using an inhaler, consumption of drugs, consultations with their general practitioners, morbidity (from patients'' entries on diary cards), and use of the educational material were measured. Knowledge about the use of drugs was significantly increased in the groups who received the material after three months and persisted after 12 months. Patients who had been given the tape or the book and tape increased their scores of knowledge of drugs more than patients given the book alone. Patients in all groups given the material considered that their disability was reduced. There were no other significant changes. Patients given both the book and the tape preferred the book. Patients with asthma can obtain useful information from such material. The paradoxical result whereby patients learnt more from the tape but preferred the book suggests that a distinction can be made between information that patients need, which may be acquired better from an audiocassette, and information that they want, which may be acquired better from a book.     

Engaging with the past: how #BlackLivesMatter points us to our predecessors and calls us to hope

This paper focuses on the contributions of Chris Lebron's book The Making of Black Lives Matter: The History of an Idea. Specifically, I examine his discussion of James Baldwin, Martin Luther King, Jr., and Audre Lorde and their opinions about love for their community, black self-actualization, and black liberation. I consider whether or not rage should play a role in our opinions about the #BlackLivesMatter movement and discuss whether or not it hurts the pursuit of freedom. I agree with the importance to look to the past in order to inform our political behaviour moving forward. Nonetheless, if we are to align with the #BlackLivesMatter movement, we must be willing to challenge what is often considered to be “proper” dissent. The review concludes with hypotheses about what black Americans should do as we work to reimagine a society where oppression is not integral to the maintenance of the American project.     

‘Inscribing’ Freud: A Critical Review of Celia Brickman's Aboriginal Populations in the Mind

Working through the particular book under review, this essay seeks to demonstrate how certain entrenched positions in postcolonial feminist writings on psychoanalysis are unproductive. Instead of advancing knowledge and understanding of the human psyche, of society or of therapeutic technique, ideas in the human sciences and psychoanalysis are shown to be appropriated and distorted in order to sustain an academic self‐referential circuitry. The central argument of Brickman's book is that current psychoanalytic practice is inherently racist because Freud's metapsychology was informed by evolutionist ideas. The present discussion attempts to uncover the techniques of bias with which the author tries to substantiate her claim.     

The United States of the United Races: a rejoinder

I respond to a review by C. Matthew Snipp, revisiting how my book connects abolitionist leanings to acceptance of racial mixing in the Early Republic. I reiterate that, contrary to the reviewer's claims, the book does not suggest that the defence of interracial marriage has been a thriving social movement. I correct his reading of my chapter on the Civil War era, referring to both the variety of voices present, and the claims of reformers' opponents, who were the only ones who claimed racial mixing was an aim of the abolitionist movement. Lastly, I defend The United States of the United Races against Professor Snipp's characterization of it as a work anticipating a ‘post-racial’ ideal, embodied by racially mixed people, who would be the end point of the obsolescence of race as a relevant analytic tool.     

From Hippocrates to facsimile: Protecting patient confidentiality is more difficult and more important than ever before

Although patient confidentiality has been a fundamental ethical principle since the Hippocratic Oath, it is under increasing threat. The main area of confidentiality is patient records. Physicians must be able to store and dispose of medical records securely. Patients should be asked whether some information should be kept out of the record or withheld if information is released. Patient identity should be kept secret during peer review of medical records. Provincial legislation outlines circumstances in which confidential information must be divulged. Because of the "team approach" to care, hospital records may be seen by many health care and administrative personnel. All hospital workers must respect confidentiality, especially when giving out information about patients by telephone or to the media. Research based on medical-record review also creates challenges for confidentiality. Electronic technology and communications are potential major sources of breaches of confidentiality. Computer records must be carefully protected from casual browsing or from unauthorized access. Fax machines and cordless and cellular telephones can allow unauthorized people to see or overhear confidential information. Confidentiality is also a concern in clinical settings, including physicians'' offices and hospitals. Conversations among hospital personnel in elevators or public cafeterias can result in breaches of confidentiality. Patient confidentiality is a right that must be safeguarded by all health care personnel.     

Fifty years of invasion ecology – the legacy of Charles Elton

The publication, in 1958, of Charles Elton's book The ecology of invasions by animals and plants launched the systematic study of biological invasions. Invasion ecology has grown to become an important multi‐disciplinary subfield of ecology with growing links to many other disciplines. This paper examines the citation history of Elton's book using the Web of Science. We also examine Elton's influence in shaping the current research agenda in invasion ecology, for which we use the 28 papers in a special issue of Diversity and Distributions (Volume 14: 2) as a representative sample. After 50 years, Elton's book remains the most cited single source in the field (> 1500 citations), and is cited more often every year (> 100 times) than any other invasion‐related publication, including influential papers in journals. Most citations to Elton's book refer to particular topics/concepts covered in the book, rather than citing it as a general reference about invasions. The shift in the distribution of topics/concepts cited with reference to Elton over time follows the same trend as for biogeography and ecology in general (increasing emphasis on analytical studies, multi‐scale analyses, multi‐disciplinary studies, etc.). Some topics emphasized by Elton are still the focus of current research (dispersal and spread of invasive organisms, impact on biodiversity, role of disturbance and enemy release) but several prominent themes in modern studies were not addressed by Elton. The emergence of new themes can be attributed to a general change in approach and emphasis underpinning research questions in conservation biogeography and applied ecology over the last half century (risk analysis, multi‐scale comparisons, propagule pressure, experimental approaches) and to the recent emergence and increasing availability of large data sets on the distribution of introduced species and to the emergence of key technologies (e.g. geographic information systems, modelling techniques, including niche‐based modelling, and molecular methods). Half a century after its publication, Charles Elton's book on invasions remains influential, but massive changes in the status of invasions and other environmental issues worldwide, together with advances in technology, are reshaping the game rules and priorities of invasion ecology.     

Neurodegeneration in Parkinson's Disease: Interactions of Oxidative Stress,Tryptophan Catabolites and Depression with Mitochondria and Sirtuins

The biological underpinnings to the etiology and course of neurodegeneration in Parkinson's disease are an area of extensive research that has yet to produce an early biological marker or disease-slowing or preventative treatment. Recent conceptualizations of Parkinson's disease have integrated immuno-inflammation and oxidative and nitrosative stress occurring in depression, somatization and peripheral inflammation into the course of Parkinson's disease. We review the data showing the importance of immuno-inflammatory processes and oxidative and nitrosative stress in such classically conceived ‘comorbidities’, suggesting that lifetime, prodromal and concurrent depression and somatization may be intricately involved in the etiology and course of Parkinson's disease, rather than psychiatric comorbidities. This produces a longer term developmental perspective of Parkinson's disease, which incorporates tryptophan catabolites (TRYCATs), lipid peroxidation, sirtuins, cyclic adenosine monophosphate, aryl hydrocarbon receptor, and circadian genes. This integrates wider bodies of data pertaining to neuronal loss in Parkinson's disease, emphasizing how these interact with susceptibility genes to drive changes in mitochondria, blood–brain barrier permeability and intercellular signalling. We review this data here in the context of neurodegeneration in Parkinson's disease and to the future directions indicated for slowing disease progression.     

Reification of social systems

In his 1991 book, Intraspecific Variation in the Social Systems of Wild Vertebrates, Dale Lott¹ reviews the evidence that a single social system does not characterize a species. Rather, he says, the longer a species is studied and the wider the range of habitats in which it is studied, the more variation is discovered. I strongly recommend this book as a concise review of recent studies on nonprimate vertebrates for anyone needing a comparative perspective on a question that deeply concerns students of primates. The clarity of Lott's exposition led me to ask several questions. If differences in the behavior of populations can be described in terms of differences in the behavior of individuals, what is gained by speaking in terms of a social system? What is a social system anyway? Is it possible that the social system is a concept that might actually get in the way of understanding social behavior?

In this book review, the title of one of Song and Ding's books was incorrectly given as Urbanization Challenges in China: Critical Issues in an Era of Rapid Growth, with an incorrect publication date of 2009. The actual title is Urbanization in China: Critical Issues in an Era of Rapid Growth, and the book was published in 2007.     

An analysis of book review criteria and motivation

Abstract. The book review process for multi-authored volumes such as symposia proceedings and compendia is analysed and discussed. The criteria used in book reviewing as listed by Keddy (1991) as well as a set of new ones have been screened in a selection of 142 multi-authored volumes reviewed in Ecology, Journal of Ecology, Vegetatio, and Journal of Vegetation Science. Too often many important book review criteria have not been taken into account at all. Use of a standard set of book review criteria is suggested to avoid personal bias as much as possible.     

Causality,menopause, and depression: a critical review of the literature.

OBJECTIVE: To assess whether causal criteria can be used to find out whether there is support in published research for maintaining that menopause causes depression. DESIGN: Ninety four articles from 30 years of research examining the relation of natural menopause to depression were traced by using Medline and systematic follow up of reference lists. Specified exclusion and inclusion criteria were applied, and the resulting 43 epidemiological primary research articles were classified and tabulated according to sample and measures used and the researchers'' own conclusion as to whether or not an association had been established. This material was qualitatively evaluated with Hill''s nine criteria for causality. RESULT: There is insufficient evidence at present to maintain that menopause causes depression. In addition to methodological and statistical problems, a temporal problem in the menopause concept hinders research in this area. CONCLUSION: Causal criteria can usefully be used to structure a literature review. Further theoretical work is required to integrate standard clinical epidemiological concepts.     

Dr. Max King: the sad life and early death of Mackenzie King's physician brother

While researching her best-selling biography, Mrs. King: The Life and Times of Isabel Mackenzie King, CMAJ contributing editor Charlotte Gray discovered a wealth of information about Dr. Dougal Macdougall (Max) King. Although he never became as famous as his older brother Mackenzie, Gray presents a convincing argument that Dr. Max King''s life and early death speak volumes about medicine and the medical profession at the turn of the century. She also argues that Mackenzie King''s own life would have been much different had his brother not died at the too young age of 42. Gray''s book was nominated for the Viacom Award, which honours the best nonfiction book published annually in Canada.     

Recognizing and reporting adverse drug reactions.

Although physicians in practice are most likely to see patients with adverse drug reactions, they may fail to recognize an adverse effect or to attribute it to a drug effect and, when recognized, they may fail to report serious reactions to the US Food and Drug Administration (FDA). To recognize and attribute an adverse event to a drug effect, physicians should review the patient''s clinical course, looking at patient risk factors, the known adverse reactions to the suspected drug, and the likelihood of a causal relationship between the drug and the adverse event-based on the temporal relationship, response to stopping or restarting the drug, and whether other factors could explain the reaction. Once an adverse drug reaction has been identified, the patient should be informed and appropriate documentation made in the patient''s medical record. Serious known reactions and all reactions to newly released drugs or those not previously known to occur (even if the certainty is low) should be reported to the FDA.     

Form–meaning links in the development of visual word recognition

Learning to read takes time and it requires explicit instruction. Three decades of research has taught us a good deal about how children learn about the links between orthography and phonology during word reading development. However, we have learned less about the links that children build between orthographic form and meaning. This is surprising given that the goal of reading development must be for children to develop an orthographic system that allows meanings to be accessed quickly, reliably and efficiently from orthography. This review considers whether meaning-related information is used when children read words aloud, and asks what we know about how and when children make connections between form and meaning during the course of reading development.
