The informationist in Australia: a feasibility study.

OBJECTIVES: A clinical informationist could provide the best available published evidence in response to clinicians' questions identified during the process of care. This study sought to assess the feasibility of an informationist service and to propose a model for its delivery in an Australian teaching hospital. Whilst similar services are increasing in the UK, with a long history in the USA, this is the first Australian study in an acute public hospital. METHODS: The views of 40/49 (82%) medical staff at the Daw Park Repatriation General Hospital, South Australia were canvassed using a questionnaire designed to address key issues relating to a proposed service. RESULTS: Doctors were receptive to its potential benefits, perceived it as relevant and likely to be used, and were interested in a pilot. They typically indicated a required response time of 24 h. They expressed limited concerns other than a likely high workload for such a service, and reported currently searching infrequently for evidence in response to clinical questions, citing time issues and unavailability of computers as current key barriers to pursuing clinical questions. CONCLUSIONS: An informationist service is feasible. Results suggest that a pilot could be run in an area of acute medicine where questions about therapy and diagnosis are likely to proliferate, and the informationist should attend consultant ward rounds and clinical meetings, aiming to provide a response within 24 h.

What do clinicians want from us? An evaluation of Brighton and Sussex University Hospitals NHS Trust clinical librarian service and its implications for developing future working patterns.

BACKGROUND: The Clinical Librarian (CL) Service at Brighton was established in 2003 with the aim of providing high-quality evidence to designated teams and fostering an evidence-based culture. OBJECTIVE: To evaluate the CL service at Brighton and discuss the implication of the findings. METHODS: A combination of internally collected data (n = 167), and an external evaluation of the service by questionnaires (n = 86) of users and non-users and interviews (n = 9) of users. RESULTS: Internal data suggest that the service is valued by its users and that patient care and continuing professional development are the most common uses for searches (confirmed by the external study); that searches generally result in some change in knowledge; and that this knowledge is disseminated. The external study found that visibility of the CL was crucial to the effectiveness of the role and that clinicians used the service mostly to get access to a wider range of resources and/or to save time. Users wanted the CL to include evaluative annotation with the results, and for the CL role to become more embedded in the team. Interview results expanded on the issues of integration of the CL and the need for annotation of results. CONCLUSIONS: To be most effective, CLs would be dedicated to one team, but financial constraints make this unlikely. Alternative working patterns are suggested as a possible compromise.

Clinical medical librarian impact on patient care: a one-year analysis.

The primary role of the clinical medical librarian (CML)--locating and providing quality-filtered, patient-specific information to physicians--has been questioned recently because of the dramatic rise in end-user searching. This study administered a questionnaire to evaluate the current impact of this service in a major hospital setting with a long established CML program. The study showed that the CML provided house officers with information that affected patient care (defined as diagnosis, diagnostic tests, or treatment) between 40% and 59% of the time. This was true even though most physicians reported they generally researched the question prior to consulting the CML. In addition, the house officers in this study indicated that they distributed the CML-provided information to other health care providers 56%-96% of the time. Based on these limited results, it appears that CMLs can continue to provide information that has a strong impact on patient care, despite the availability of an end-user local MEDLINE system.

Kallikrein multigene families and the regulation of their expression.

Tissue kallikreins are a group of closely related serine proteinases that are represented by multigene families in mice and rats. The existence of similar, large, kallikrein-like gene families in other mammalian species is currently a matter of dispute. We have surveyed a number of vertebrate species using genomic DNA Southern blotting and screened a human genomic library with a monkey kallikrein cDNA probe. The hybridization patterns of the genomic Southern blots and the characterization of 19 independent human clones using restriction analysis and Southern blotting indicate that other mammalian species may have multiple kallikrein-like genes as well. The regulatory mechanisms that govern the expression, activity, and bioavailability of tissue kallikreins are likewise complex. At the level of transcription, hormones, dietary factors, and tissue-specific factors are known to affect the expression of tissue kallikrein genes. At the posttranslational level, kallikrein activity and bioavailability are regulated by enzymatic activation, circulating autoantibodies, and binding proteins. We have demonstrated the presence of kallikrein-binding proteins in humans and rats, and, furthermore, we have shown reduced levels of this binding protein in a hypertensive rat model.

Determination of continuing medical education needs of clinicians from a literature search study, Part I. The study.

Continuing medical education is an area of current concern to health sciences librarians. A comprehensive study of literature searches requested by physicians and by fourth-year medical students serving their five-week preceptorship with a rural physician was conducted: (1) to determine if there is any pattern to the requests received so that areas of study for continuing medical education can be ascertained; and (2) to determine whether there is any appreciable difference in nature and complexity between those searches requested by clinicians and those requested by medical student preceptees. Literature search requests were examined in terms of individual MeSH subjects, subcategories, and categories for each subject covered in every search. This analysis has demonstrated that assessing the clinical problems of practicing physicians may be one method of determining needed continuing medical education topics.

A descriptive study of ninety-two hospital libraries in Mexico.

This work reports on the existing situation of ninety-two hospital libraries, located at Mexico's Social Security Institute (IMSS). A descriptive, systems approach was used to explore the physical structure and space of the libraries, staff, furniture, equipment, collections, services, organization and management, and users. Structured interviews were applied to each hospital library, and a questionnaire was used as a tool to collect data. A "control" system, designed to measure the status of each library, was applied through the assignment of values to several indicators, derived from IMSS policy manuals. This procedure helped to identify which library was "more" or "less" adequate to IMSS standards. Within the rank of 10 to 1 (10 = optimum; 1 = minimum), the mean rank of IMSS hospital libraries was 6. The major deficiencies found were those related to furniture (ranked 4) and services (ranked 5) and the lack of library professionals found in 92% of the libraries.

[The utilization of Medline for the solution of real clinical problems. A prospective study in Italy].

AIM: Measure of usefulness of Medline searches requested for clinical problems. METHODS: open prospective uncontrolled study lasted for 3 months. Collection of online or CD-ROM Medline searches operated by clinicians or librarians at 5 biomedical libraries. User interviews about use and usefulness of Medline, recorded with a closed-answer self-administered questionnaire, adapted from a U.S. National Library of Medicine product. RESULTS: Of the 6 participating libraries, one was excluded from analysis from data collection inadequacies. Among 668 searches, 55 (8.2%) were produced for real patients. Physicians judgement about clinical usefulness of their searches (available for 46 cases) indicate a significant importance for diagnostic evaluation (23%) and therapy administration (46%). After applying search results into clinical practice, clinicians think that positive outcomes are achieved in the doctor-patient-family relationship area (19%), a better use of health care system facilities is obtained (26%) and, less consistently, positive effects are perceived on longevity (5%), abnormality correction (10%), symptomatic relief (7%) and functional recovery (6%). CONCLUSION: Physicians judge that Medline searches actually can contribute to diagnosis and treatment of real patients, with significant benefits on the process of care, on doctor-patient relationship and on patient's health.

A survey of expressed genes in Caenorhabditis elegans.

As an adjunct to the genomic sequencing of Caenorhabditis elegans, we have investigated a representative cDNA library of 1,517 clones. A single sequence read has been obtained from the 5' end of each clone, allowing its characterization with respect to the public databases, and the clones are being localized on the genome map. The result is the identification of about 1,200 of the estimated 15,000 genes of C. elegans. More than 30% of the inferred protein sequences have significant similarity to existing sequences in the databases, providing a route towards in vivo analysis of known genes in the nematode. These clones also provide material for assessing the accuracy of predicted exons and splicing patterns and will lead to a more accurate estimate of the total number of genes in the organism than has hitherto been available.

Use study of Excerpta Medica abstract journals: to drop or not to drop?

The directors of the Claude Moore Health Sciences Library, a medium-sized library serving the University of Virginia medical and nursing schools, were concerned over the increasing cost of periodical subscriptions and so studied the use of the printed copy of Excerpta Medica. This study had six parts: (1) availability in other campus libraries; (2) staff perceptions of in-library use; (3) results of studies performed by other libraries in the United States; (4) recorded in-library use; (5) users' opinions; and (6) personal interviews with library users and with selected departments tht corresponded with the forty-four subject areas of Excerpta Medica. The user-survey parts (4 and 5) elicited few responses, but personal interviews allowed a good look at levels of use and interest. The overall results convinced staff to drop some sections and publicize those that remained.

Novel transcripts of the estrogen receptor alpha gene in channel catfish.

Complementary DNA libraries from liver and ovary of an immature female channel catfish were screened with a homologous ERalpha cDNA probe. The hepatic library yielded two new channel catfish ER cDNAs that encode N-terminal ERalpha variants of different sizes. Relative to the catfish ERalpha (medium size; 581 residues) previously reported, these new cDNAs encode Long-ERalpha (36 residues longer) and Short-ERalpha (389 residues shorter). The 5'-end of Long-ERalpha cDNA is identical to that of Medium-ERalpha but has an additional 503-bp segment with an upstream, in-frame translation-start codon. Recombinant Long-ERalpha binds estrogen with high affinity (K(d) = 3. 4 nM), similar to that previously reported for Medium-ERalpha but lower than reported for catfish ERbeta. Short-ERalpha cDNA encodes a protein that lacks most of the receptor protein and does not bind estrogen. Northern hybridization confirmed the existence of multiple hepatic ERalpha RNAs that include the size range of the ERalpha cDNAs obtained from the libraries as well as additional sizes. Using primers for RT-PCR that target locations internal to the protein-coding sequence, we also established the presence of several ERalpha cDNA variants with in-frame insertions in the ligand-binding and DNA-binding domains and in-frame or out-of-frame deletions in the ligand-binding domain. These internal variants showed patterns of expression that differed between the ovary and liver. Further, the ovarian library yielded a full-length, ERalpha antisense cDNA containing a poly(A) signal and tail. A limited survey of histological preparations from juvenile catfish by in situ hybridization using directionally synthesized cRNA probes also suggested the expression of ERalpha antisense RNA in a tissue-specific manner. In conclusion, channel catfish seemingly have three broad classes of ERalpha mRNA variants: those encoding N-terminal truncated variants, those encoding internal variants (including C-terminal truncated variants), and antisense mRNA. The sense variants may encode functional ERalpha or related proteins that modulate ERalpha or ERbeta activity. The existence of ER antisense mRNA is reported in this study for the first time. Its role may be to participate in the regulation of ER gene expression.

A survey of genes in Eimeria tenella merozoites by EST sequencing.

A study of about 500 expressed sequence tags (ESTs), derived from a merozoite cDNA library, was initiated as an approach to generate a larger pool of gene information on Eimeria tenella. Of the ESTs, 47.7% had matches with entries in the databases, including ribosomal proteins, metabolic enzymes and proteins with other functions, of which 14.3% represented previously known E. tenella genes. Thus over 50% of the ESTs had no significant database matches. The E. tenella EST dataset contained a range of highly abundant genes comparable with that found in the EST dataset of T. gondii and may thus reflect the importance of such molecules in the biology of the apicomplexan organisms. However, comparison of the two datasets revealed very few homologies between sequences of apical organelle molecules, and provides evidence for sequence divergence between these closely-related parasites. The data presented underpin the potential value of the EST strategy for the discovery of novel genes and may allow for a more rapid increase in the knowledge and understanding of gene expression in the merozoite life cycle stage of Eimeria spp.
