[Authors' affiliations and addresses in published articles. Lack of care penalizes French universities in international rankings].

OBJECTIVE: To assess, through the example of the université Claude Bernard Lyon 1, whether the poor international visibility of French universities may be due in part to a lack of care by researchers in listing their affiliations and address on their scientific publications. METHOD: Querying the heading "address" of Medline, Embase.com and Pascal Biomed for 2003 in searches for publications from Université Claude Bernard Lyon 1. RESULTS: In 300 bibliographic entries studied, we found 44 different forms of the university's name. Only 15% of the addresses were correct, and 44% did not mention the author's affiliation with the university. DISCUSSION: Authors' lack of care in listing their affiliations and address and the absence of a standardized official name for the university may explain the poor visibility of French universities. Recommendations about this topic might help to promote the reputation and work of French researchers internationally.

[Usefulness of online bibliographic research in biomedical research, with an application to the epidemiologic study of genetic osteopathy].

The bibliographic research online is an useful means of recovering information in all the subjects, particularly in the field of biomedicine. In fact, this instrument allows researchers to get information in a rapid, complete and up-to-date way. The aim of the present review is to describe the usefulness of the bibliographical research online in the field of the genetic osteopathies. These are rare disorders: so, their own rarity makes the bibliographical research online necessary to carry out a large and effective comparison of experiences. The obtained results are amply reported in the manuscript. For instance, we verified that chondrodysplasias are the diseases most represented in the literature, while melorheostosis the disorder less mentioned. Moreover, we evidenced that some hereditary disorders of connective tissue, such as Marfan's syndrome, osteogenesis imperfecta and Ehlers-Danlos syndrome, are strongly influenced by race, sex and age.

[Scientific production in public health and the international bibliographic data bases].

This study begins by briefly situating the development of indexing procedures in the scientific literature, dating to the latter half of the 19th century. Next, taking public health in Latin America as its reference, it analyzes the current use of indexing for the evaluation of scientific production, and thus that of scientific periodicals. The argument is that for various reasons, international indexing should not be used as the only parameter for evaluating the impact of Latin American scientific production in public health. Criteria other than impact indices should be developed to promote a broader understanding of the dynamics of scientific production in the Latin America public health field.

Management of bibliographic information by Dutch researchers in general practice.

BACKGROUND: As a result of changes in information technology and the rapid growth of publications methods of searching the literature have changed. Systematic searching of the growing literature has become very important. It is not known whether researchers in general practice search systematically, and whether they have incorporated computerized sources in their research practice. OBJECTIVES AND METHODS: We aimed to assess the methods of literature research used by GPs. We interviewed eight GP researchers, two information specialists and a psychologist working in primary health care organizations. RESULTS: The GP researchers began their search in their private book collections, or asked colleagues for information. Later in the search process, they used computerized information sources. Medline on CD-ROM and the computer-based indexes of two Dutch journals were most widely used. The GPs found it difficult to locate the appropriate terms to describe their research questions. Knowledge of the methodology of literature research, and skills required to use the information sources efficiently were lacking. There was a need for instruction and training in the use of information sources. GPs need a telephone help desk where their questions can be answered adequately. CONCLUSIONS: GP researchers search the literature unsystematically. Although computerized databases were being used, knowledge and skills related to the use of these information sources must be improved.

On-line access to a cost-benefit/cost-effectiveness analysis bibliography via CDC WONDER.

The Centers for Disease Control and Prevention (CDC) is undertaking an assessment of prevention effectiveness; using information from cost-benefit and cost-effectiveness analysis (CBA/CEA) studies will be integral to this effort. To facilitate this work, a bibliography of articles that discusses both the costs and consequences of personal health services has been created. For 1979 to 1990, 3,206 articles were identified and classified into more than 250 topics. To provide simplified, readily available access to this resource in a system in which searches would not be key-word dependent, the authors created an on-line version of the bibliography and incorporated it into CDC WONDER, the CDC's on-line public health information system. Users can limit their queries by traditional bibliographic criteria (author, journal, publication type, year of publication, and country of origin); the full text of the abstract; or criteria particular to the CBA/CEA bibliography (topic, study type, and medical function). Having the CBA/CEA bibliography in CDC WONDER allows it to be searched and updated easily and also permits researchers to create personalized subsets of references. This on-line bibliography should help researchers in their efforts to identify gaps in knowledge of the relationship between costs and outcomes and the role of prevention in controlling health care expenditures.

[Primary care research in the Valencia community. Original articles published over a 4-year period (1990-1993)].

OBJECTIVE: To evaluate the quality of Primary Care (PC) research in the Community of Valencia through research articles. DESIGN: Descriptive study. SETTING: Primary Care in the community of Valencia. PATIENTS AND OTHER PARTICIPANTS: Research articles on PC published 1990-1993 by professionals from the Community of Valencia in: Atención Primaria, Medicina Clínica, Revista Clínica Española and Gaceta Sanitaria. MEASUREMENTS AND MAIN RESULTS: 43 articles published between 1990 and 1993 (6, 6, 9 and 22, respectively) were obtained from the Medline and Indice Médico Español (Spanish Medical Index) bases. Characteristics of the study, authors and bibliographic references were analysed. The greatest number of studies were published in Atención Primaria (81%), making up consistently about 10% of the annual total of articles in this journal. A descriptive design and inferential statistical analysis (comparison of proportions) were mainly used. Average number of authors was 5.14 (C.I. 95%, 4.7 - 5.6). The participation of residents (39%) was greater than that of family doctors and below that of other specialists, suggesting a certain disenchantment with research. The collaboration of different centres (49%) was high, fundamentally Health Centres among themselves and with universities. CONCLUSIONS: PC research in the Community of Valencia appears to be experiencing similar growth to that in the rest of Spain.

Selection of information resources for education in medical pharmacology.

Pharmacology is the foundation science of medical pharmacotherapy. Education in medical pharmacology (EP) requires the use of information resources (IR) to meet the challenge of the continuous introduction of new drugs and new educational, didactic and pedagogical theories to enhance knowledge. Hence criteria for selecting bibliographic material for EP should be clearly outlined and implemented. In this work we present a method to select IR for EP based on systems theory and focusing on the factors determining: (a) the integration of a list of recommended IR for EP; (b) the design of the acquisition list for faculty and students work; (c) the overall organization of the resources available for its optimal use and benefit in the educational process; and (d) a general strategy for assessing the impact of the bibliographic infrastructure. The proposal is based on information from: (i) lists of recommended readings in the academic program of the Pharmacology course given at the School of Medicine of UNAM in the last 30 years; (ii) the extent of discipline development measured by two indexes derived from the contents of Goodman and Gilman's "Pharmacological Basis of Therapeutics" (G & G); (iii) the number of texts currently found in the collection of FM-UNAM which are classified in the section of Pharmacology using the Library of Congress Classification System (LCCS); and (iv) the comparison of academic versus standardized classification of pharmacology topics, such as Medical Subject Heading (MESH) and LCCS The importance of this proposal relates to its usefulness for EP and for other medical disciplines.

Mapping the literature of allied health: project overview.

The Nursing and Allied Health Resources Section of the Medical Library Association (MLA) created the Task Force on Bibliographic Access for the Allied Health Literature to identify the core journals of various allied health fields and assess the coverage given these titles by the major indexing and abstracting services. The larger objective is to influence increased bibliographic access to the core literature. This paper introduces the Project for Mapping the Literature of Allied Health and the common bibliometric methodology used for the five specific studies reported in the accompanying papers. Findings relating to format used, age of citations, dispersion of literature, and indexing coverage for the different fields are compared. Journals are the most heavily cited format. Fields differ by the currency of cited material, with physical therapy and speech language pathology displaying use of the oldest citations. The set of core journals is small for each field, particularly in speech-language pathology. MEDLINE provided the strongest indexing coverage overall, followed by EMBASE. Information such as that reported by the project can help librarians in improving information transfer for the allied health professionals they serve.

[Automation of medical literature--and information services].

It is important for clinical practice to be able to find (or retrieve) relevant literature and to keep informed of the state of medical science. The fact that the contents of articles in journals are now accessible via computers is the result of integration of bibliographic techniques, medical knowledge and computer technology. Articles published in some 5000 medical journals can nowadays be retrieved electronically via Medline and Embase together (but medical literature in Dutch is underrepresented). Computerised insertion of publications into Internet dose not make information traceable or accessible, let alone reliable and readable. It cannot be predicted if electronic versions of scientific periodicals will replace the printed editions completely. However, valuable, reliable information will always have its price, even on Internet. It is unlikely that electronic information published privately (internet) will replace scientific publishers soon, for readers will still want selection and monitoring of contents and language. Good layout, professional typography and suitable illustrations to enhance reading comfort and cognitive processes, will even become more important. The problems arising from the immensity of scientific knowledge are not (any longer) of a technological nature-what is needed is a cultural about-turn of the information infrastructure in medical-scientific associations, organizations and institutions.

An overview of the electronic health and safety services of the Canadian Centre for Occupational Health and Safety.

This article describes the electronic information services of the Canadian Centre for Occupational Health and Safety (CCOHS). The aim of CCOHS is to promote a healthier and safer workplace. CCOHS' key ways of achieving this are its CD-ROM (compact disc read-only memory) service, CCINFOdisc, and its on-line computer network called, CCINFOline. CCOHS' electronic services contain some 50 databases with bibliographic and factual information from CCOHS and major organizations in other countries, such as NIOSH (National Institute for Occupational Safety and Health) in the U.S., the International Occupational Safety and Health Information Centre (CIS) in Switzerland, and the Institut National de Recherche et de Sécurité (INRS) in France. In addition, the CD-ROM service includes The Chemical Advisor disc of regulatory and advisory lists for chemicals from the U.S. and other countries; full-text discs, such as CANADIAN HEALTH AND SAFETY LEGISLATION and two interactive, multimedia education and training products on the safe use of chemicals, and on preventing repetitive motion injuries. These services, available at an affordable price, are delivered worldwide and currently have thousands of organizations as subscribers in about 50 countries. Founded by the Government of Canada in 1978, CCOHS is the national resource in occupational health and safety information. In addition to the electronic service, other services offered are an inquiry service, which is free in Canada, and a publications service.

Autologous transfusion techniques: a systematic review of their efficacy.

Shortages of donor blood and fears of transmitted infections have prompted the use of a range of blood-sparing techniques in the peri-operative period. We conducted a systematic review of three techniques that involve the re-infusion of a patient's blood--pre-operative autologous blood deposit (PAD), acute normovolaemic haemodilution (ANH), and cell salvage (CS). We examined the effects of these interventions on the need for peri-operative allogeneic red blood cell transfusion and on clinical outcomes. Controlled clinical studies were identified by computer searches of comprehensive electronic databases and bibliographic searches of published articles. The literature search retrieved a total of 68 randomized trials (RCTs) and 81 controlled observational studies that included data from over 34 000 individuals. In summary, the RCTs found that autologous transfusion techniques consistently reduced the frequency of allogeneic transfusions, with intervention effect sizes ranging from a relative 63% reduction (95% CI 46-74%) with PAD, to 42% (27-53%) with CS and to 31% (16-44%) with ANH. Non-randomized studies reported larger effect sizes than RCTs. PAD increased overall transfusion rates by 30% (95% CI 12-48%) and reduced pre-operative haemoglobin levels by an average of 1.23 g dL(-1). Intervention effects were substantially reduced when these techniques were performed under transfusion protocols. Interpretation of the studies was hampered by serious methodological weaknesses, particularly inadequate randomization techniques, unblinded measurements and the subjective nature of the outcome variables. The studies reported few clinical outcome and adverse event data. Previous claims regarding reduced rates of mortality and infection with autologous transfusions were not confirmed.

[Brazilian scientific journals in speech-language and hearing science: impact indicator].

BACKGROUND: Global value of scientific papers published in national journals of the Brazilian Speech-language and Hearing Science analyzed through the Impact Factor (IF). PURPOSE: To analyze part of the Brazilian Speech-Language and Hearing Science through its scientific journals: characterization of the impact indicator--in this case the Impact Factor (IF). Seven national Speech-language and Hearing Science journals (1986/ 2001) registered in the Brazilian Institute of Information in Science and Technology (Ibict) and with a given International Standard Serial Number (ISSN) were analyzed. In order to calculate the IF of the scientific journals, the lists of bibliographic references of the published papers were consulted and the original formula of Garfield was used, adapting it to the seven journals. Bibliographic references cited in the research papers, in the case studies, in the review and update articles were considered for analyses. Researches which were cited in the summaries like letters to the editors; editorial, abstracts, commentaries and others were excluded. A total of 9,334 bibliographic references of 549 papers were analyzed, excluding self-citations of authors. It was observed that the resulting IFs revealed practically null values. The obtained results demonstrate that the Brazilian Speech-language and Hearing Science needs to develop a few aspects of its editorial and scientific processes--the researches of the Brazilian Speech-language and Hearing Science are being lost, making it necessary for the editors to raise the access and visibility of their journals and for the speech-language and hearing scientists to cite the work of their antecessors and national partners. According to the obtained data, for the Brazilian Speech-language and Hearing Science, the publication of 11.9 papers is necessary for only one of these papers to be cited in another research. It is observed that the IFs of the Brazilian Speech-language and Hearing Science, among these seven journals, have risen since 1999, suggesting a development of this Science. The follow up of this research, analyzing the years subsequent to 2001, is necessary in order to verify the real raise of the impact of these articles.

Online medical books: their availability and an assessment of how health sciences libraries provide access on their public Websites.

OBJECTIVE: The objective of this study was to determine the number and topical range of available online medical books and to assess how health sciences libraries were providing access to these resources on their public Websites. METHOD: The collection-based evaluative technique of list checking was used to assess the number and topical range of online medical books of the six largest publishers. Publisher inventory lists were downloaded over a two-day period (May 16-17, 2004). Titles were counted and compared with the 2003 Brandon/Hill list. A sample of health sciences libraries was subsequently derived by consulting the 2004 "Top Medical Schools-Research" in U.S. News & World Report. Bibliographic and bibliothecal access methods were evaluated based on an inspection of the publicly available Websites of the sample libraries. RESULTS: Of 318 currently published online medical books, 151 (47%) were Brandon/Hill titles covering 42 of 59 Brandon/Hill topics (71%). These 151 titles represented 22% (N = 672) of the Brandon/Hill list, which further broke down as 52 minimal core, 41 initial purchase, and 58 other recommended Brandon/Hill titles. These numbers represented 50%, 28%, and 12%, respectively, of all Brandon/Hill titles corresponding to those categories. In terms of bibliographic access, 20 of 21 of sampled libraries created catalog records for their online medical books, 1 of which also provided analytical access at the chapter level, and none provided access at the chapter section level. Of the 21 libraries, 19 had library Website search engines that provided title-level access and 4 provided access at the chapter level and none that at the chapter section level. For bibliothecal access, 19 of 21 libraries provided title-level access to medical books, 8 of which provided classified and alphabetic arrangements, 1 provided a classified arrangement only, and 10 provided an alphabetic arrangement only. No library provided a bibliothecal arrangement for medical book chapters or chapter sections. CONCLUSIONS: This study shows that the number and topical range of online medical books is reaching a point where collection-level consideration is warranted to facilitate efficient use and to prevent the problem of split files. However, the results also show that few efforts are underway on the publicly available Websites of the surveyed health sciences libraries to provide the analytical access necessary to meet the structural needs of clinical information seekers.

Evidence-based medicine in nephrology: identifying and critically appraising the literature.

BACKGROUND: Uncertainties about best management of end-stage renal disease (ESRD) are reflected in wide variations in practice. Systematic reviews aim to reduce uncertainty by strengthening the evidence base for clinical practice, allowing estimation of the benefits and risks of particular interventions, whilst minimizing the potential for bias. This paper describes the methods and conduct of six systematic reviews of aspects of the management of ESRD, and the yield in terms of trials found. METHODS: Our methodology was based on that recommended by the Cochrane Collaboration (an international initiative set up to perform and disseminate systematic reviews of health care). It involved a systematic search of electronic databases and bibliographic reference lists, together with handsearching of Kidney International for studies relevant to the management of ESRD, followed by a systematic assessment of study quality. RESULTS: Around 12,000 abstracts were assessed which had been identified from electronic sources. Of these, 2085 (18%) were deemed to be reports of possible randomized or quasi-randomized controlled trials relevant to the management of ESRD. Three hundred and forty were relevant to the six specific reviews, and after assessment of the full manuscripts, 39 studies were finally included in our reviews. Reports of a further nine trials, which were identified from other sources, were also included. The broad search adopted allowed the parallel development of a register of trials of all aspects of the management of ESRD. CONCLUSIONS: This study has demonstrated that the methodology of systematic reviews, as promoted by the Cochrane Renal Group, is feasible but has significant resource implications. The development of a register of randomized controlled trials (RCTs) related to the management of ESRD will facilitate this form of research in the future.

Bibliometric study of grey literature in core veterinary medical journals.

OBJECTIVES: Grey literature has been perceived by many as belonging to the primary sources of information and has become an accepted method of nonconventional communication in the sciences and medicine. Since little is known about the use and nature of grey literature in veterinary medicine, a systematic study was done to analyze and characterize the bibliographic citations appearing in twelve core veterinary journals. METHODS: Citations from 2,159 articles published in twelve core veterinary journals in 2000 were analyzed to determine the portion of citations from grey literature. Those citations were further analyzed and categorized according to the type of publication. RESULTS: Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were considered to be grey literature. Four veterinary specialties, internal medicine, pathology, theriogenology, and microbiology, accounted for 70% of the total number of articles. Three small-animal clinical practice journals cited about 2.5-3% grey literature, less than half that of journals with basic research orientations, where results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of the grey literature appeared as conferences, government publications, and corporate organization literature. CONCLUSIONS: The results corroborate other reported research that the incidence of grey literature is lower in medicine and biology than in some other fields, such as aeronautics and agriculture. As in other fields, use of the Internet and the Web has greatly expanded the communication process among veterinary professionals. The appearance of closed community email forums and specialized discussion groups within the veterinary profession is an example of what could become a new kind of grey literature.

[Publication languages of Impact Factor journals and of medical bibliographic databanks].

BACKGROUND AND OBJECTIVE: A preference for English-language sources during determination of Journal Impact Factors (IF) was discussed, IF being published in the annual Journal Citation Reports (JCR). The JCR are derived from data in Science Citation Index (SCI). The aim of this study was, therefore, (i) to review publication countries and languages in JCR, (ii) publication languages in SCI in comparison to further recognised medical bibliographic databanks. METHODS: Searching (i) countries and languages in JCR Science-Editions 1997 and 1998, (ii) language distributions in publication years 1995 - 2000 in bibliographic databanks SCI, MEDLINE (ME) and EMBASE (EM). RESULTS: (i) Almost 70 % journals in JCR 1997 and 1998 were published in USA, United Kingdom, or The Netherlands. Of two language options present, a number of English-classified journals contained >90 % articles in other languages, whereas >90 % publications in English could occur in Multi-Language (ML) journals, thereby complicating statistical comparisons. 83,9 % JCR-periodicals in 1997 and 85,6 % in 1998 were classified English. English/ML ratios increased exponentially with increasing IF. (ii) 95,5 % of the articles documented 1995 - 2000 in whole SCI and in our constructed SCI segment >>Medicine and related areas<< were written in English, compared to 88,5 % in ME and 89,8 % in EM. The SCI Medicine segment was 15 % more comprehensive than either MEDLINE or EMBASE. Highly significant differences of language distributions in SCI vs. MEDLINE and especially SCI vs. EMBASE were observed. Retrieval rates in SCI of German-, French-, Japanese- and Chinese-language medical papers published in 2000 were impressively augmented by EMBASE and MEDLINE. CONCLUSIONS: (i) Anglo-American publishers' countries and English-language journals prevail in JCR with respect to numbers and IF levels. Publication language English favours citation frequency. (ii) Of databanks studied, SCI shows a maximum preference for English-language sources, thereby causing an English Language Bias during IF derivation.

Accessing the scientific literature. The reality of virtual scholarship.

The age-honored practice of plowing through the Index Medicus in a good medical library to meander through citations for treasured finds is an anachronism. Today, clinicians have the astonishing capacity to bring to bear existing knowledge almost effortlessly. Virtual scholarship makes available up-to-date medical citations and their abstracts. There can be access around the clock on any topic in the office, at the bedside, or from home. Computerized searches of the medical literature promote directed continuing education and may enhance clinical care of patients.
