Word Sense Disambiguation of clinical abbreviations with hyperdimensional computing.
(59/68)
Automated Word Sense Disambiguation in clinical documents is a prerequisite to accurate extraction of medical information. Emerging methods utilizing hyperdimensional computing present new approaches to this problem. In this paper, we evaluate one such approach, the Binary Spatter Code Word Sense Disambiguation algorithm, on 50 ambiguous abbreviation sets derived from clinical notes. This algorithm uses reversible vector transformations to encode ambiguous terms and their context-specific senses into vectors representing surrounding terms. The sense for a new context is then inferred from vectors representing the terms it contains. One-to-one BSC-WSD achieves average accuracy of 94.55% when considering the orientation and distance of neighboring terms relative to the target abbreviation, outperforming Support Vector Machine and Naive Bayes classifiers. Furthermore, it is practical to deal with all 50 abbreviations in an identical manner using a single one-to-many BSC-WSD model with average accuracy of 93.91%, which is not possible with common machine learning algorithms.

Understanding Latin abbreviations: a survey.
(61/68)
A questionnaire was sent to general practitioner principals and trainees and to retail pharmacists in the west of Scotland to ascertain how well they translated 20 Latin abbreviations. The results showed that pharmacists had a high level of understanding, but that general practitioner principals and trainees misunderstood some of the less commonly used terms. Misunderstanding was more likely among trainee general practitioners than principals. (+info)
Physiologic significance of hemodynamic measurements and their derived indices.
(62/68)
The fundamental value of hemodynamic monitoring is that it provides direct physiological measurements. The appropriate use of these requires an understanding of normal cardiac physiology and its alterations in certain disease states. An appreciation of the determinants of cardiac output, coronary blood flow and myocardial oxygen consumption will improve the interpretation and subsequent manipulation of these values when one is confronted with them clinically.

MEDLARS abbreviations for medical journal titles.
(63/68)
The National Library of Medicine announces its adoption of the Anglo-American standard for the formulation of journal title abbreviations according to the American National Standard for the Abbreviation of Titles of Periodicals (1969), with individual words abbreviated, in turn, according to the International List of Periodical Title Word Abbreviations (1970). The history of the activity of the specific Z39 Committee of USASI (now ANSI) concerned with journal title abbreviations is reviewed, covering the period from 1962 to the present. A history of the National Clearinghouse for Periodical Title Word Abbreviations and of the International List is also given. Former NLM usage is compared with the forms of the present International List and examples show the major changes in NLM abbreviations. The NLM Rules for Abbreviation of Periodical Titles as derived from the new standard are appended. (+info)
Short counseling techniques for busy family doctors.
(64/68)
OBJECTIVE: To introduce two short counseling skills for busy family doctors: the BATHE technique and the DIG technique. QUALITY OF EVIDENCE: The BATHE technique indicates five areas for questioning patients who require counseling: background, affect, trouble, handling, and empathy. No research on use of the technique has been published. The DIG technique is the author's modification of the BATHE technique. MAIN FINDINGS: While the efficacy of counseling in general was validated, more research on the effectiveness on these two techniques needs to be done. CONCLUSIONS: Since counseling is an integral part of family practice, family doctors will find these techniques useful. Each is easy to learn and takes less than 15 minutes to complete. (+info)
