Health information for patients: The hospital library's role.

Libraries today, including most hospital-based patients' libraries, are involved only peripherally in providing patient health science information. Hospital libraries should collaborate with health professionals in getting health information to patients--along with the library's more traditional roles of providing recreational reading for patients and serving the informational needs of the physician and medical staff. The library should act as the center for educational materials and programs within the hospital. Many health agencies, health educators, physicians, and librarians have been discussing the need for patient health education, but there are few effectively organized or established education centers. This paper discusses an overview of patient health education and intellectural freedom, proposes a new role for the existing hospital library in patient health education, and suggests guidelines for establishing a patient education center.

The Veterans Administration Library Network: VALNET.

Given substantial federal budget cuts and ever-increasing quantities of print and nonprint material, Veterans Administration (VA) Library Services have pooled their resources in a network to improve the scope and efficiency of the services they provide. The VA Library Network, VALNET, composed of 176 libraries, serves health care facilities throughout the continental United States and Puerto Rico. This paper outlines VALNET's organization and the range of individual VA Library Services. It also describes centrally provided services and resource-sharing tools being developed by the VA, as well as significant sharing arrangement among VA Library Services and between the VA and non-VA libraries.

The idea of the library in the twenty-first century.

The fundamental idea of the library must change. The nineteenth-century idea of the library as the embalming of dead genius and the twentieth-century idea of the library as the repository for second-hand knowledge must give way to the idea of the library as the owner and the librarian as the manager of first-hand knowledge. In the coming era of knowledge capitalism, those individuals and organizations will flourish who are able to apply knowledge to create knowledge and to organize it to produce knowledge. The roles of present-day librarians and libraries will begin to differentiate sharply over the next decade. Some must seize the opportunity to participate in the transformation of libraries into online knowledge servers.

The impact of medical libraries and literature on patient care in New Zealand.

This paper reports the results of a survey of 372 physicians working in regional hospitals in New Zealand. The survey was undertaken to determine if these physicians used their local medical library and what impact the literature obtained had on patient care. The 295 respondents (80.6% of the sample) expressed genuine interest in their library, with most visiting the library once a week or more. Patient care was ranked as the main reason for their visit; the second most important reason was keeping up-to-date on the latest research. Physicians indicated that information obtained at the library was used to confirm or change diagnoses, medications, or diagnostic tests, or to change advice given to patients. Information also was used to make decisions concerning early discharge, avoidance of hospital admission, or transfer of patients to another hospital. The survey also addressed the use of librarian services, sources of information used, and physicians' purchase of textbooks and journals. All comments by respondents were supportive of the library. The significance of libraries to clinical decision making, especially in small hospitals, is discussed.

Assessing and addressing the library needs of health care personnel in a large regional hospital.

A needs assessment survey was conducted by the Medical Library staff of St. John's Health System, Inc., in Springfield, Missouri, to document the library needs of non-physician health care personnel. The intended use of the survey was threefold: first, to collect baseline data from non-physician health care employees; second, to gather recommendations from both library users and non-users to be included in library planning and improvements; and third, to promote the library during the survey process. Study results, along with an implementation report detailing actions taken to enhance strengths and address weaknesses identified in the needs assessment survey, are presented. Opportunities for further investigation of library needs are also reported.

NOAH--New York Online Access to Health: library collaboration for bilingual consumer health information on the Internet.

New York Online Access to Health (NOAH) is a Web site that provides accurate, timely, relevant, and unbiased full-text health information in both English and Spanish. A joint project of The City University of New York Office of Library Services, The New York Academy of Medicine Library, the Metropolitan New York Library Council, and The New York Public Library, NOAH brings consumer health information to the public in New York City and around the world via the Internet. NOAH is an example of a successful collaboration among different types of libraries (academic, public, medical society) and voluntary health agencies to use new technologies to reach a very broad public. This paper discusses the involvement of the library partners in terms of the management and funding of the site. Web site construction is described including how the information is gathered and organized. Future plans and funding issues for NOAH are considered in terms of the expected increase in the need for consumer health information. NOAH can be reached at: www.noah.cuny.edu.

Academic medical center libraries on the Web.

Academic medical center libraries are moving towards publishing electronically, utilizing networked technologies, and creating digital libraries. The catalyst for this movement has been the Web. An analysis of academic medical center library Web pages was undertaken to assess the information created and communicated in early 1997. A summary of present uses and suggestions for future applications is provided. A method for evaluating and describing the content of library Web sites was designed. The evaluation included categorizing basic information such as description and access to library services, access to commercial databases, and use of interactive forms. The main goal of the evaluation was to assess original resources produced by these libraries.

The evolution of rural outreach from Package Library to Grateful Med: introduction to the symposium.

Outreach is now a prevailing activity in health sciences libraries. As an introduction to a series of papers on current library outreach to rural communities, this paper traces the evolution of such activities by proponents in health sciences libraries from 1924 to 1992. Definitions of rural and outreach are followed by a consideration of the expanding audience groups. The evolution in approaches covers the package library and enhancements in extension service, library development, circuit librarianship, and self-service arrangements made possible by such programs as the Georgia Interactive Network (GaIN) and Grateful Med.

SOURCE MATERIALS AND THE LIBRARY: THE DISPERSION OF THE BEAUMONT PAPERS.

The author discusses the confusion, attributable to misleading references, which long obscured the location of the main portion of the William Beaumont papers. The collection was previously thought to be in the National Library of Medicine, but it is actually housed in the Washington University School of Medicine Library. This has been clarified by the discovery of a series of previously unpublished letters of Sir William Osler, as well as by other newly found materials. The history of the Washington University School of Medicine Library is reviewed, and the facts relating to the disposition of the Beaumont collection in that library rather than the National Library of Medicine are told. Also considered are some of the problems which the dispersion of documentary source materials creates for the scholar. With the Beaumont papers as a case in point, various locations of such materials are cited, and their contents briefly noted.

Standards for the academic veterinary medical library.

The Standards Committee of the Veterinary Medical Libraries Section was appointed in May 2000 and charged to create standards for the ideal academic veterinary medical library, written from the perspective of veterinary medical librarians. The resulting Standards for the Academic Veterinary Medical Library were approved by members of the Veterinary Medical Libraries Section during MLA '03 in San Diego, California. The standards were approved by Section Council in April 2005 and received final approval from the Board of Directors of the Medical Library Association during MLA '04 in Washington, DC.

Perspectives on academic health sciences libraries in the 1980s: indicators from a Delphi study.

A Delphi study was undertaken to identify the changes in library roles and functions that the directors of academic health sciences libraries believe will occur over the next decade. The methodology is described and the results are summarized. Two scenarios resulted: one, highly desirable; the other, highly probable. They overlap by 64%. Library directors expect moderate evolutionary changes in the next ten years. Users are perceived to be the force maintaining the status quo, while technology is the force advancing change. The adoption of technology is seen as desirable and within the libraries' span of control. Education and service roles of librarians will expand. Library and institutional priorities are seen as obstacles to change.

Preparation of fluorescence quenched libraries containing interchain disulphide bonds for studies of protein disulphide isomerases.

Protein disulphide isomerase is an enzyme that catalyses disulphide redox reactions in proteins. In this paper, fluorogenic and interchain disulphide bond containing peptide libraries and suitable substrates, useful in the study of protein disulphide isomerase, are described. In order to establish the chemistry required for the generation of a split-synthesis library, two substrates containing an interchain disulphide bond, a fluorescent probe and a quencher were synthesized. The library consists of a Cys residue flanked by randomized amino acid residues at both sides and the fluorescent Abz group at the amino terminal. All the 20 natural amino acids except Cys were employed. The library was linked to PEGA-beads via methionine so that the peptides could be selectively removed from the resin by cleavage with CNBr. A disulphide bridge was formed between the bead-linked library and a peptide containing the quenching chromophore (Tyr(NO2)) and Cys(pNpys) activated for reaction with a second thiol. The formation and cleavage of the interchain disulphide bonds in the library were monitored under a fluorescence microscope. Substrates to investigate the properties of protein disulphide isomerase in solution were also synthesized.

Design, docking, and evaluation of multiple libraries against multiple targets.

We present a general approach to the design, docking, and virtual screening of multiple combinatorial libraries against a family of proteins. The method consists of three main stages: docking the scaffold, selecting the best substituents at each site of diversity, and comparing the resultant molecules within and between the libraries. The core "divide-and-conquer" algorithm for side-chain selection, developed from an earlier version (Sun et al., J Comp Aided Mol Design 1998;12:597-604), provides a way to explore large lists of substituents with linear rather than combinatorial time dependence. We have applied our method to three combinatorial libraries and three serine proteases: trypsin, chymotrypsin, and elastase. We show that the scaffold docking procedure, in conjunction with a novel vector-based orientation filter, reproduces crystallographic binding modes. In addition, the free-energy-based scoring procedure (Zou et al., J Am Chem Soc 1999;121:8033-8043) is able to reproduce experimental binding data for P1 mutants of macromolecular protease inhibitors. Finally, we show that our method discriminates between a peptide library and virtual libraries built on benzodiazepine and tetrahydroisoquinolinone scaffolds. Implications of the docking results for library design are explored.

Identification of chymotrypsin inhibitors from a second-generation template assisted combinatorial peptide library.

In an earlier study (McBride JD, Freeman N, Domingo GJ, Leatherbarrow RJ. Selection of chymotrypsin inhibitors from a conformationally-constrained combinatorial peptide library. J. Mol. Biol. 1996; 259: 819-827) we described a resin-bound cyclic peptide library, constructed based on the sequence of the anti-tryptic reactive site loop of Bowman Birk Inhibitor (BBI), a proteinase inhibitor protein. This library was used to identify re-directed chymotrypsin inhibitors with Ki values as low as 17 nM. We have now extended this work by constructing an enhanced library in which a further position, at the P4 site of the inhibitor, has been randomized. This new library has variation at three target locations (P4, P1 and P2) within the inhibitory loop region, producing 8,000 variants. Screening this library allowed selection of new inhibitor sequences with Ki values as low as 3.4 nM. The success of this approach is reflected by the fact that the inhibition constant given by the selected peptide sequence is slightly lower than that reported against chymotrypsin for the most studied full length BBI protein, Soybean BBI 2-IV.

Identification of novel polyphenol oxidase inhibitors by enzymatic one-pot synthesis and deconvolution of combinatorial libraries.

The feasibility of enzymatic synthesis of combinatorial libraries using multifunctional starting materials [i.e., 2,4-dihydroxy-N-(2-hydroxyethyl)benzamide, 1; 4-hydroxyphenethyl alcohol, 2; 3,5-dihydroxybenzyl alcohol, 3; and 4-hydroxybenzyl alcohol, 4] with six vinyl esters, in a one-pot reaction, was investigated. Candida antarctica lipase was employed as a biocatalyst. The resulting 24-compound library contained all the expected species with no significant bias toward particular combinations of substrates. As expected, the library contained a substance(s) that showed significant inhibition of polyphenol oxidase, which was used as a model target. The deconvolution was accomplished via resynthesis of ten partial libraries, which were prepared with either an equimolar mixture of the four alcohols and a single vinyl ester, or a single alcohol and equimolar mixture of the activated esters. Analysis of the inhibition pattern observed with these partial libraries suggested that 4-hydroxybenzyl benzoate (4e) should be the most potent inhibitor. This conclusion was confirmed by the preparation and comparison of all 24 components of the initial library. Finally, it was shown that 4e was a competitive inhibitor of polyphenol oxidase, with a K(i) of 40 microM. This value compared favorably with a K(i) of 400 microM, which was determined for parent phenol 4.

Major histocompatibility complex class I allele-specific peptide libraries: identification of peptides that mimic an H-Y T cell epitope.

We describe a novel method for screening large libraries of random peptides for T cell antigens. Two libraries were constructed, containing fixed amino acids representing the major histocompatibility complex (MHC) class I anchor residues for H-2Kb-restricted octamers and H-2Db-restricted nonamers. Peptides from the Kb-restricted library (KbL: SXIXFXXL) and the Db-restricted library (DbL: XXXXNXXXIM) specifically stabilize empty Kb and Db molecules, respectively. The libraries contain peptides that mimic several H-2b-restricted cytotoxic T lymphocyte epitopes, and 21 mimotopes for a Db-restricted H-Y epitope were isolated. A degenerate synthetic peptide of limited complexity containing the identified H-Y sequence motif was found to be similar to the natural H-Y epitope by reverse-phase high performance liquid chromatography analysis. This peptide is also capable of immunizing female mice against male splenocytes. Several applications for MHC-restricted peptide libraries are discussed.

A BAC library for the goldfish Carassius auratus auratus (Cyprinidae, Cypriniformes).

A goldfish (Carassius auratus auratus) bacterial artificial chromosome genomic library (BAC library) was constructed from one aquarium-bred male specimen (tetraploid, 4n=100, genome size=3.52 pg/cell). The library consists of 128,352 positive clones with an average insert size of 150.4 kb, covering the genome 11-fold. All clones were spotted onto nylon filters and thus are available for screening of genomic regions of interest, such as candidate genes, gene families, or large-sized syntenic DNA regions of cyprinid species. Preliminary screens with two genes were conducted with hybridizing probes to the genes RAG1 and lgi1. RAG1 is a single-copy gene in zebrafish and is duplicated in C. a. auratus. We found a very close correlation between the number of positive BAC clones and the expected library coverage. Two copies of lgi1 were found in zebrafish. We have detected four different copies in C. a. auratus, not in the expected abundance, which indicates some variation in the coverage of the BAC library. The preliminary screens indicate that many duplicated genes that resulted from the ancient fish-specific genome duplication persist in the tetraploid goldfish genome. Hence, the BAC library will provide a useful resource for the future work on comparative genomics, polyploidy, diploidization, and evolutionary genomics in fishes.

Identification and cloning of a new category of DNA fragments which are poorly represented in human genomic libraries.

We have developed an alternative strategy for the preparation of genomic libraries that ensures better representation of genomic sequences commonly underrepresented in genomic libraries constructed using standard protocols. To overcome the apparent bias against genomic sequences containing clusters of restriction sites we have used nonoptimized restriction digestions to generate a mixture of DNA fragments which have been cloned into the EMBL3 vector. To validate this protocol we have screened the EMBL3 library to identify a full length genomic clone of the prolactin-inducible gene (PIP). Screening 4 other, commercially available, genomic libraries prepared using standard protocols for restriction digestion of the genomic DNA failed to identify any full length clones. We show that this increase in the representation of the full length PIP gene in the EMBL3 genomic library is attributable to the method of insert preparation used and suggests that an additional subset of sequences that may be poorly represented in, or absent from, established libraries may be cloned using this modified protocol.
