Cohort studies in health sciences librarianship.

QUESTION: What are the key characteristics of the cohort study design and its varied applications, and how can this research design be utilized in health sciences librarianship? DATA SOURCES: The health, social, behavioral, biological, library, earth, and management sciences literatures were used as sources. STUDY SELECTION: All fields except for health sciences librarianship were scanned topically for either well-known or diverse applications of the cohort design. The health sciences library literature available to the author principally for the years 1990 to 2000, supplemented by papers or posters presented at annual meetings of the Medical Library Association. DATA EXTRACTION: A narrative review for the health, social, behavioral, biological, earth, and management sciences literatures and a systematic review for health sciences librarianship literature for the years 1990 to 2000, with three exceptions, were conducted. The author conducted principally a manual search of the health sciences librarianship literature for the years 1990 to 2000 as part of this systematic review. MAIN RESULTS: The cohort design has been applied to answer a wide array of theoretical or practical research questions in the health, social, behavioral, biological, and management sciences. Health sciences librarianship also offers several major applications of the cohort design. CONCLUSION: The cohort design has great potential for answering research questions in the field of health sciences librarianship, particularly evidence-based librarianship (EBL), although that potential has not been fully explored.

Complementary competencies: public health and health sciences librarianship.

OBJECTIVES: The authors sought to identify opportunities for partnership between the communities of public health workers and health sciences librarians. METHODS: The authors review competencies in public health and health sciences librarianship. They highlight previously identified public health informatics competencies and the Medical Library Association's essential areas of knowledge. Based on points of correspondence between the two domains, the authors identify specific opportunities for partnership. RESULTS: The points of correspondence between public health and health sciences librarianship are reflected in several past projects involving both communities. These previous collaborations and the services provided by health sciences librarians at many public health organizations suggest that some health sciences librarians may be considered full members of the public health workforce. Opportunities remain for productive collaboration between public health workers and health sciences librarians. CONCLUSIONS: Drawing on historical and contemporary experience, this paper presents an initial framework for forming collaborations between health sciences librarians and members of the public health workforce. This framework may stimulate thinking about how to form additional partnerships between members of these two communities.

Clinical librarianship: a systematic review of the literature.

Clinical librarianship (CL), currently receiving renewed interest world-wide, seeks to provide quality-filtered information to health professionals at the point of need to support clinical decision-making. This review builds upon the work of Cimpl (Bulletin of the Medical Library Association 1985, 73, 21-8) and attempts to establish the evidence base for CL. The objectives were to determine, from the literature, whether CL services are used by clinicians, have an effect on patient care, and/or clinicians' use of literature in practice and/or are cost-effective. The methodology used was a systematic review of the literature, following, where possible, the NHS Centre for Reviews and Dissemination (CRD) framework. Modifications to this methodology included the resources searched, and the critical appraisal checklist (CriSTAL) used. Two hundred and eighty-four unique references were retrieved. Seventeen (16 unique) evaluative and a further 33 descriptive studies met the inclusion criteria. The quality of reporting of the literature was generally poor. CL programmes appear to be well-used and received by clinicians. However, there is insufficient evidence available on their effect on patient care, clinicians' use of literature in practice, and their cost-effectiveness, thus highlighting the need for further high-quality research.

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.

The CCPN data model for NMR spectroscopy: development of a software pipeline.

To address data management and data exchange problems in the nuclear magnetic resonance (NMR) community, the Collaborative Computing Project for the NMR community (CCPN) created a "Data Model" that describes all the different types of information needed in an NMR structural study, from molecular structure and NMR parameters to coordinates. This paper describes the development of a set of software applications that use the Data Model and its associated libraries, thus validating the approach. These applications are freely available and provide a pipeline for high-throughput analysis of NMR data. Three programs work directly with the Data Model: CcpNmr Analysis, an entirely new analysis and interactive display program, the CcpNmr FormatConverter, which allows transfer of data from programs commonly used in NMR to and from the Data Model, and the CLOUDS software for automated structure calculation and assignment (Carnegie Mellon University), which was rewritten to interact directly with the Data Model. The ARIA 2.0 software for structure calculation (Institut Pasteur) and the QUEEN program for validation of restraints (University of Nijmegen) were extended to provide conversion of their data to the Data Model. During these developments the Data Model has been thoroughly tested and used, demonstrating that applications can successfully exchange data via the Data Model. The software architecture developed by CCPN is now ready for new developments, such as integration with additional software applications and extensions of the Data Model into other areas of research.

Glass/ceramic/refractory techniques, their development and introduction into dentistry: A historical literature review.

This review considered the development of glass, ceramic, refractory materials, and techniques over a period of 25,000 years, from the time of stone-age man to their introduction into dentistry. Currently a wide variety of all-ceramic dental restorations are provided using alumina-reinforced, leucite-forming, and novel glass and ceramic materials along with a range of refractory materials and associated techniques. However, some of the problems of dimensional and thermal change experienced by early craftsmen still persist during current laboratory fabrication techniques. Early English archaeological and dental publications were obtained through the Archaeology Education Department of the British Museum in London and the Archives of the British Dental Association Library. More recent peer-reviewed articles published from 1966 to the present were obtained through MEDLINE.

International cooperation and the European Association for Health Information and Libraries.

This paper describes cooperation between European libraries: what EAHIL hopes to achieve, and how it may be done. Since its founding in 1987, EAHIL has been working for professional development and to improve cooperation and exchange of experience amongst its members. In 1995 a working programme entitled 'EAHIL--Aims towards year 2000' was approved, and it consolidates some of the most important aims of EAHIL. In this paper, only three of the six aims are referred to: conferences and workshops arranged by EAHIL, the development of an efficient network system in order to increase communication and information among members, and the establishment of agreements for cooperation with medical and health science libraries in Eastern and Central Europe in particular.

Interaction of protein inhibitor of activated STAT (PIAS) proteins with the TATA-binding protein, TBP.

Transcription activators often recruit promoter-targeted assembly of a pre-initiation complex; many repressors antagonize recruitment. These activities can involve direct interactions with proteins in the pre-initiation complex. We used an optimized yeast two-hybrid system to screen mouse pregnancy-associated libraries for proteins that interact with TATA-binding protein (TBP). Screens revealed an interaction between TBP and a single member of the zinc finger family of transcription factors, ZFP523. Two members of the protein inhibitor of activated STAT (PIAS) family, PIAS1 and PIAS3, also interacted with TBP in screens. Endogenous PIAS1 and TBP co-immunoprecipitated from nuclear extracts, suggesting the interaction occurred in vivo. In vitro-translated PIAS1 and TBP co-immunoprecipitated, which indicated that other nuclear proteins were not required for the interaction. Deletion analysis mapped the PIAS-interacting domain of TBP to the conserved TBP(CORE) and the TBP-interacting domain on PIAS1 to a 39-amino acid C-terminal region. Mammals issue seven known PIAS proteins from four pias genes, pias1, pias3, piasx, and piasy, each with different cell type-specific expression patterns; the TBP-interacting domain reported here is the only part of the PIAS C-terminal region shared by all seven PIAS proteins. Direct analyses indicated that PIASx and PIASy also interacted with TBP. Our results suggest that all PIAS proteins might mediate situation-specific regulatory signaling at the TBP interface and that previously unknown levels of complexity could exist in the gene regulatory interplay between TBP, PIAS proteins, ZFP523, and other transcription factors.

Veterinary education in the era of information technology.

A major innovation in the delivery of the veterinary curriculum is being implemented at The University of Melbourne using the subject of systematic bacteriology and mycology as a pilot project. Students receive course information as interactive, multimedia databases. These consist of text and an associated library of catalogued digital images, movies and sounds. The databases employ a hypermedia information system to achieve efficient integration within and between subjects. The new delivery method encourages greater autonomy and more active learning roles for students than occurs in traditionally taught courses. Students will use their databases as the principal resource of information for undergraduate studies. A unique feature of this system for delivering the curriculum is that students will modify and expand their databases during the course. The ultimate aim is for students at graduation to receive, on disc, a copy of their own databases, adapted by themselves to their particular future professional needs. As graduate veterinarians they will continue to use their databases as a major resource for information and learning, thus providing continuity from undergraduate to continuing postgraduate education.

Language matters: the vocabulary of racism in health care.

Race equality as a matter of governance has gained momentum in most Western countries and is reflected in race/ethnicity data collection in administrative systems and the attention accorded to terminology by census agencies. However, the vocabulary of health care--both in its literature and the language of officialdom--has proved resistant to the use of this lexicon of acceptable terms, as exemplified by the portrayal of peoples as 'Oriental' and 'Negro'. What makes such language racist is the historical legacy it carries--that is, its symbolic importance. Survey evidence shows that the majority of those so described find the terms offensive. Countries have dealt with these linguistic issues in a variety of ways, including the use of the legislature and action by library associations and professional bodies in the USA. In Britain it has fallen upon the judiciary and universities to prohibit such terms. Given the momentum currently being achieved by public authorities in their response to race equality legislation, it is now time for health care to purge its language of these epithets.

Canada urgently needs a national network of libraries to access evidence.

Canadian health professionals and their patients are deprived of important evidence to guide health and healthcare decisions, ensure quality and avoid unnecessary deaths because, unlike other developed countries, Canada does not have a national medical library as can be found in the United States' National Library of Medicine and the United Kingdom's National Health Service.

Collection development and outsourcing in academic health sciences libraries: a survey of current practices.

Academic health sciences libraries in the United States and Canada were surveyed regarding collection development trends, including their effect on approval plan and blanket order use, and use of outsourcing over the past four years. Results of the survey indicate that serials market forces, budgetary constraints, and growth in electronic resources purchasing have resulted in a decline in the acquisition of print items. As a result, approval plan use is being curtailed in many academic health sciences libraries. Although use of blanket orders is more stable, fewer than one-third of academic health sciences libraries report using them currently. The decline of print collections suggests that libraries should explore cooperative collection development of print materials to ensure access and preservation. The decline of approval plan use and the need for cooperative collection development may require additional effort for sound collection development. Libraries were also surveyed about their use of outsourcing. Some libraries reported outsourcing cataloging and shelf preparation of books, but none reported using outsourcing for resource selection. The reason given most often for outsourcing was that it resulted in cost savings. As expected, economic factors are driving both collection development and outsourcing practices.

Mapping the literature of cytotechnology.

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature.
