Mapping the literature of home health nursing.

OBJECTIVES: The purpose of this study was to identify core journals in home health nursing and to determine how well these journals were covered by indexing and abstracting services. The study was part of the project for mapping the nursing literature of the Medical Library Association's Nursing and Allied Health Resource Section. METHODS: A citation analysis of two core journals was done to determine distribution of references by format types and age of citations and dispersion of the literature, according to Bradford's Law of Scattering. The analysis of indexing coverage for Zone 1 and 2 was also provided. RESULTS: The study showed that 64.2% of citations came from journals, versus 22.9% from books and 12.9% from other publications. PubMed/ MEDLINE rated highest in average indexing coverage of Zone 1 and 2 journals, followed by CINAHL. PsycINFO, SocioAbstracts, and EBSCO Health Business FullTEXT showed practically no coverage for the home health nursing literature. CONCLUSION: As expected, journal articles were found to be the primary source for referencing and books, the secondary source. In regard to bibliographic control, no databases provided full coverage of the journals in the field of home health nursing. PubMed/MEDLINE and CINAHL gave better results in combination, because CINAHL tended to cover more nursing journals, while PubMed/MEDLINE did better with medical titles.

A systematic review of the prognosis of acute whiplash and a new conceptual framework to synthesize the literature.

STUDY DESIGN: Systematic review of prognostic studies of acute whiplash. OBJECTIVES: To update the systematic review on the prognosis of acute whiplash published by the Quebec Task Force on Whiplash-Associated Disorders and to propose a new conceptual framework to conduct systematic reviews on prognosis. SUMMARY OF BACKGROUND DATA: In 1995, the Quebec Task Force published a systematic review of the literature on whiplash and concluded that its prognosis is favorable. However, few prognostic factors were identified. Recent studies have added to this knowledge, and there is a need to update the review conducted by the Quebec Task Force. METHODS: A bibliographic search of four electronic databases was performed to identify prognostic studies of acute whiplash published after 1995. The literature was appraised with standard review criteria. The consistency of evidence across studies was assessed. A conceptual framework was designed to classify the literature according to methodologic quality, target population, and phases of investigation. RESULTS: Thirteen cohort studies were included in the review. The framework used in this study demonstrates that most of the recent prognostic studies are descriptive in nature. The prognosis of acute whiplash varies according to the population sampled and the insurance/compensation system under which individuals are allowed to claim benefits. Besides age, gender, baseline neck pain intensity, baseline headache intensity, and baseline radicular signs and symptoms, there is little consistency in the literature about the prognostic factors for the recovery of whiplash. CONCLUSIONS: Scant knowledge about the prognosis of whiplash has been gained since the release of the Quebec Task Force report. However, it is becoming obvious that the insurance and compensation systems have a large impact on recovery from acute whiplash injuries. The conceptual framework used in this study demonstrates that large cohort studies investigating a wide range of prognostic factors are necessary to improve the understanding of this problem.

An implementation of the trigram phrase matching method for text similarity problems.

The representation of texts by term vectors with element values calculated by a TFIDF method yields to significant results in text similarity problems, such as finding related documents in bibliographic or full-text databases and identifying MeSH concepts from medical texts by lexical approach and also harmonizing journal citation in ISI/SciELO references and normalizing author's affiliation in MEDLINE. Our work considered "trigrams" as the terms (elements) of a term vector representing a text, according to the Trigram Phrase Matching published by the NLM's Indexing Initiative and its logarithmic Term Frequency-Inverse Document Frequency method for term weighting. Trigrams are overlapping 3-char strings from a text, extracted by a couple of rules, and a trigram matching method may improve the probability of identifying synonym phrases or similar texts. The matching process was implemented as a simple algorithm, and requires a certain amount of computer resources. An efficiency-focused C-programming was adopted. In addition, some heuristic rules improved the efficiency of the method and made it feasible a regular "find your scientific production in SciELO collection" information service. We describe an implementation of the Trigram Matching method, the software tool we developed and a set of experimental parameters for the above results.

[Research into learning disabilities: a documentary analysis].

INTRODUCTION: Our current understanding of learning disabilities (LD) is essentially limited by their actual definition, the heterogeneity of the samples and the unsuitability of the control groups. AIMS: This study offers an overview of the methodological aspects and the areas of research in LD. DEVELOPMENT: From a bibliographical search conducted in the Psychological Abstracts database, PsycINFO, we identified and selected the studies the review was to focus on, and this was completed with previous reviews. Quantitative research methods are preferred in 99.7% of cases, whereas the remaining 0.3% opted for qualitative methods. There was in increase in the number of research reviews, as well as longitudinal studies and those aimed at determining the effectiveness of the interventions, with the resulting interest in new techniques for data analysis such as meta-analysis, path analysis and latent growth curves. The research topics that aroused most interest were LD-related problems (16.7%), difficulties in learning to read (15.82%), studies focusing on intervention (10.15%) and diagnostics in LD. CONCLUSIONS: The primary objectives of the research appear to be the characterisation of LD and the problems they cause throughout the patient's life cycle, together with their identification and early treatment. Research is also extended towards other, more practical matters, with a special emphasis on the school setting.

[Applications of informatics in anesthesiology: anesthesia graphics].

Computerization has brought radical changes to anesthesiology. Quality of care, management, cost control, training, research, safety and privacy have all improved. The anesthesiologist has been freed from repetitive clerical tasks and is able to make better use of time. A graphic display of anesthesia is only one of the many computer applications available as a consequence of links created among monitoring, continuous infusion and intelligent alarm systems, automatic data collection, network monitoring and the availability of bibliographic information (through Internet connection). The computer graphic display of anesthesia is more precise, legible, complete and reliable (during critical events, in substitutions of anesthesiologists or for research) than the traditional graph. One of the greatest problems of computer graphing today--besides start-up costs--is that of inserting comments on monitoring artifacts, given that the graph is a legally valid medical document.

Deciphering Arabidopsis thaliana gene neighborhoods through bibliographic co-citations.

In the framework of genome annotation, scientific literature is obviously the major source of biological knowledge. The aim of the work described in this paper is to exploit this source of data for the model plant Arabidopsis thaliana. The first step has consisted in constituting a relevant bibliographic references dataset for plant genomic research. Genes co-citations have then been systematically annotated in this reference dataset, starting from the simple idea that if genes are cited in the same publication, they must probably share some related functional properties. In order to deal with the synonymous gene name problem, a gene name reference list has been constituted starting from A. thaliana SwissProt entries. This list was used to build clusters of co-cited genes by a single linkage procedure such that any gene in a given cluster possesses at least one co-cited partner in the same cluster. Analysis of the clusters demonstrate the biological consistency of this approach, with only very few fortuitous links. As an example, a cluster including genes related to flowering time is more deeply described in the paper. Finally, a graphical representation of each cluster was performed, which provides a convenient way to retrieve the genes (the nodes of the graphs) and the references in which they were co-cited (the edges of the graphs).

Twenty years of health care economic analysis in Spain: are we doing well?

The rising demand for health care, together with the scarce available resources, has increased the use of economic analysis as a support tool for policy making. The objective of this study was to make a description of economic evaluation studies carried out in Spain and published during the last 20 years, and to assess their quality. A systematic bibliographic search was made in the main biomedical databases. Full economic evaluation studies made in Spain comparing two or more health care alternatives were included. Statistical analyses included a descriptive analysis, the assessment of the association between pairs of variables, and a homogeneity analysis. A total of 87 studies were included in the review. According to the methodology, the technique most frequently used was cost-effectiveness analysis. In most cases, some weaknesses could be pointed out: absence of any objective directly linked to the decision-making process, a non-explicit perspective, no inclusion of indirect costs, or clinical and economical data not concurrently collected. A continuing challenge for health care economic analysis in Spain is to follow methodological guidelines and reporting conventions, to improve the dissemination of research, as well as to use more sophisticated economic analysis techniques, and to publish in international journals.

[Bibliografic resources on chemical risk administration and prevention].

BACKGROUND: The documentation produced by public and private institutions in relation to the chemical risk constitutes an essential tool for prevention. The objective of this research is to locate and to revise the documents related to the management of the prevention of chemical risk focus to PYMES in Spain from 1995 to 2004. METHODS: The methodology carried out for the selection of the bibliographical materials has been the consultation of automated databases and Web pages. RESULTS: 812 documents have been identified. Most corresponds to grey literature. The thematic more frequent has been the security and the most frequent objective of the papers has been the prevention. Most of the documents go to the technical sector. CONCLUSIONS: The results suggest that although that there is a great diversity of documents in Spain dedicated to the prevention of chemical risk it seems convenient: 1) to increase their diffusion, 2) to pay attention to the communication of the risks, 3) to investigate and to translate the research in good practice.

Past and current trends in soy supplementation: a bibliographic study.

The aim was to determine in what areas the therapeutic application of soy predominates in clinical trials and to assess the emerging fields of its use by means of an analysis of bibliographic resources. A search was performed in the MEDLINE database up to 31 december 2004, limited to the Title/Abstract field, and Clinical Trials as the type of publication. The abstracts from the publications selected (n=86) were reviewed and different variables were assessed. A total of 3280 subjects were included: 15% men and 59% women (71% postmenopausal). The studies were performed basically in healthy individuals (71%). Twenty five percent of the studies investigated plasma levels of different metabolites and 21% determined hormone or lipid profiles. After the year 2000 a new population focus was detected, with the publication of two studies in elite gymnasts and judoists, with positive results. The present observations indicate that soy supplementation in the competitive sports elite may be an emerging application.

[Reference manager: a personal database on literature for consultation and word processing].

The software programme Reference manager serves as a personal database for bibliographic references within a restricted field, especially journal articles (with abstracts). Yet it is more than a digital card index. References can be retrieved via author name, keyword, title word, year of publication, or name of periodical. During the preparation of a manuscript by means of a word processor, references can be simply indicated by one or more of these characteristics. Later Reference manager transforms these provisional references automatically into a bibliography and text references, according to the style of the journal in question. The personal database does not have to be built through laborious copying, but can be captured from Medline databases. Updating with recent references is possible by means of bibliographic services such as Current contents or Reference update.

PRO-CITE as a bibliographic management tool.

Despite experiencing some difficulties, (and who hasn't when dealing with unfamiliar software), I find Pro-Cite to be both useful and user-friendly. It is easy enough for the one-professional library to implement, and has enough flexibility to meet a wide variety of patrons' needs for bibliographic information.
