Controlling hospital library theft.

At Capital Health System/Fuld Campus (formerly Helene Fuld Medical Center), the Health Sciences Library lost many books and videocassettes. These materials were listed in the catalog but were missing when staff went to the shelves. The hospital had experienced a downsizing of staff, a reorganization, and a merger. When the library staff did an inventory, $10,000 worth of materials were found to be missing. We corrected the situation through a series of steps that we believe will help other libraries control their theft. Through regularly scheduling inventories, monitoring items, advertising, and using specific security measures, we have successfully controlled the library theft. The January 2002 inventory resulted in meeting our goal of zero missing books and videocassettes. We work to maintain that goal.

[Biochemical and histologic changes in patients with chronic hepatitis C under treatment with interferon. a 5-year cohort study].

Since 1989, some schemes of treatment for Chronic hepatitis C (CHC) have been investigated, including alpha and beta interferon (IFN), ribavirin, and amantadine either alone or in combination. These studies have been performed in other countries. In our study, we investigated the outcome of Mexican patients with CHC treated with IFN. Twenty-six patients with five years follow-up treated with IFN in monotherapy were studied. We evaluated three kinds of response: sustained response (SR); non response (NR), and partial response (PR). Patients were evaluated biochemically and histologically by means of aminotransferase levels (pretreatment and serial) and hepatic biopsy (pretreatment and control). The data were obtained from clinical records. Aminotransferase levels at the end of treatment and six months later as well as histologic damage score showed the following results: 16 patients were cataloged as NR (61.5%), four as PR (15.3%), and six as SR (23.1%). Ten patients developed cirrhosis during follow-up, eight from NR group, one from PR group, and one from SR group. CHC patients treated with IFN alone obtained SR in 19% of cases; the patient who developed cirrhosis was not included. A study for longer time, prospective and protocolized to evaluate standardized IFN dose as well as evaluate combined treatment, is necessary.

[Dynamics of morphological and cytochemical changes in the placenta following cadmium chloride intoxication].

The experiments carried out for the study aimed at determining the prenatal sensitivity to cadmium in the aspect of beth morphological and functional condition of placenta. The experiments were carried out on 80 pregnant female rats divided into three experimental groups and a control one. The experimental animals were daily administered, intragastrically, aqueous solution of cadmium chloride, from the 7th to the 19th day of pregnancy, in doses differing between the experimental groups: 2, 10 and 22 mg of CdCl2 per kilogram of body weight, respectively. The animals were decapitated on the 21st day of pregnancy. Placenta sections, besides hematoxylin and eosin staining, were examined for the activity of the following enzymes: succinic dehydrogenase (SDH) E.C.1.3.99.1., lactate dehydrogenase (LDH) E.C.1.1.1.27., NADH-tetrazole reductase (NADH-t.r.), without a catalog number, and their glycogen reaction was checked. The results of the experiments proved cadmium chloride to cause considerable damage to the enzymatic apparatus of placenta, leading to energy deficit in the cells of both the fetal and the maternal part of this organ. The multienzymatic changes observed preceded the morphologic ones by far.

Development shows some backbone. HFSP Workshop on Genetic Control of Vertebrate Development cosponsored by the Human Frontier Science Program, European Science Foundation, and European Molecular Biology Organization, Les Diablerets, Switzerland, May 26-30, 1991.

This meeting aptly illustrated the power of a combined analysis of development in a range of vertebrate systems. Each system has its own inherent strengths: the mouse has gene transfer technology and targeted mutagenesis, the frog and chick have experimental embryology, and the zebrafish has genetics. It is the synergistic effect of considering all of these systems in combination that is without measure. In the past, the study of vertebrate development has been relegated to a largely descriptive phase. Initially, this was through analysis of morphological changes taking place during development. More recently, this has taken the form of cataloging the expression patterns of genes transcribed in development. It is clear that we are now entering an era when a functional analysis of development can get underway.

Regulatory mechanisms in cell-mediated immune responses. II. Comparison of culture-induced and alloantigen-induced suppressor cells in MLR and CML.

Two antigen-nonspecific T cell-dependent suppressor systems were compared for their effects upon CML and MLR. Suppressor cells generated by an in vitro culture of spleen cells were compared with suppressor cells generated by in vivo priming with alloantigen. Culture-induced suppressor cells were themselves unable to respond in CML or MLR; were able to suppress actively the CML and MLR responses of untreated responding cells; were mitomycin-sensitive; and, produced no easily demonstrable suppressive supernatant. Alloantigen-primed cells were able to respond in CML and LR; could suppress proliferation in MLR, but were able to suppress CML only after mitomycin treatment; and, produced suppressive supernatants active in suppressing both CML and MLR. In addition to cataloging the differences and similarities between these suppressor populations, the data have been employed to analyze the mechanisms by which suppression occurs in CML and MLR.

INTERLIBRARY COOPERATION IN SWEDEN AND THE MEDICAL PART OF THE SCANDIA PLAN.

In Sweden, as in Scandinavia generally, the interlibrary loan service is widely extended. The large research libraries traditionally follow a very liberal lending policy. Of fundamental importance to the Swedish interloan system is the maintenance of a union catalog. The free flow of materials from one library to another is facilitated by the franking privilege accorded public institutions. During the fifties, the idea arose of establishing acquisitional cooperation among the research libraries in Sweden. The highly developed interlibrary loan service was of basic significance for the realization of this project. In 1956 the possibilities were investigated of further expanding the acquisitional cooperation to include the greater libraries of Scandinavia. Thus, the so-called Scandia Plan was born. In 1960 the time was ripe to discuss the possibilities of applying the Scandia Plan to medical literature. At a meeting that year it was agreed that such cooperation could apply only to the literature which from a Scandinavian point of view would be considered peripheral. The plan was to include periodicals only, and be restricted to materials which, mainly for language reasons, are infrequently used in Scandinavian research. The task of acquiring such periodicals could be divided between the different libraries of the four countries. Such an arrangement would make it economically possible to increase the common stock of medical periodicals and avoid unnecessary duplication of material least in demand.

PROBLEMS OF MEDICAL LIBRARIES IN JAPAN.

Reference service in medical libraries should be considered more seriously by the members of the Japan Medical Library Association, as their interest so far has been focused mainly on interlibrary loan service, compilation of union lists and union catalogs, and the business side of library administration. The Association does not have enough funds to be very active, and its membership is limited to the libraries of medical and of some large dental schools. It should open its membership to other medical libraries, such as those of hospitals and medical laboratories, and eventually to individuals. Many of the member libraries do not have complete control of their own budget, as each department of the school earmarks part of its budget for the library while it still holds the right of deciding which books and journals are to be bought and keeps a large part of them in its departmental library. Lack of proper library school education among the library staff is one of the major problems. There are some training courses for medical librarians in the library schools and also some workshops held by the Association, but they are limited in their usefulness by the fact that there are not enough library school graduates who can take advantage of them.

[Nursing outcomes and the reform of care processes (III)].

Some of the deficiencies which have been detected and need be resolved in order to have a correct determination of the "nursing product" include the lack of a catalog or portfolio of services, the lack of a set standard dealing with the realm of nurses' responsibilities in assistance care, and an insufficiency in the record keeping systems which register the multiple services which nurses carry out. Nurses' diagnoses, clinical trajectories, result-based management form part of the need to make sanitary budgets economically viable. From these perspectives has come the current trend to install standardized operating procedures and to computerize them.

Programmed database system at the Chang Gung Craniofacial Center: part I.

BACKGROUND: A database is a system for the management of information. Databases of different forms are widely used in everyday life from telephone books to online library catalogs. The Craniofacial Center at Chang Gung Memorial Hospital has seen over 20,000 patients during the past 20 years. All of the patient records need to digitally input into a computer database. METHODS: A database was custom designed using Paradox 8. The ACDSee Photo browser and DOS linked them to the original program. The Paradox 8 was programmed to a standard mode for the diagnosis and treatment data input to prevent typographical errors. RESULTS: We collected the records of 25,200 patients from 1987 to 2002, of which 24,331 underwent operations. The data for 14,828 patients were registered as complete and/or incomplete cleft and the proportions of unilateral to bilateral and female to male are presented in Table 1. CONCLUSION: This new database system was designed to ensure the accuracy of data input using a standard model that is capable of correct data programming using the custom designed coding system for the Craniofacial Center. The system also provides easy and reliable data retrieval when using the powerful search tools.

Detecting and measuring rater effects using many-facet Rasch measurement: part I.

The purpose of this two-part paper is to introduce researchers to the many-facet Rasch measurement (MFRM) approach for detecting and measuring rater effects. The researcher will learn how to use the Facets (Linacre, 2001) computer program to study five effects: leniency/severity, central tendency, randomness, halo, and differential leniency/severity. Part 1 of the paper provides critical background and context for studying MFRM. We present a catalog of rater effects, introducing effects that researchers have studied over the last three-quarters of a century in order to help readers gain a historical perspective on how those effects have been conceptualized. We define each effect and describe various ways the effect has been portrayed in the research literature. We then explain how researchers theorize that the effect impacts the quality of ratings, pinpoint various indices they have used to measure it, and describe various strategies that have been proposed to try to minimize its impact on the measurement of ratees. The second half of Part 1 provides conceptual and mathematical explanations of many-facet Rasch measurement, focusing on how researchers can use MFRM to study rater effects. First, we present the many-facet version of Andrich's (1978) rating scale model and identify questions about a rating operation that researchers can address using this model. We then introduce three hybrid MFRM models, explain the conceptual distinctions among them, describe how they differ from the rating scale model, and identify questions about a rating operation that researchers can address using these hybrid models.

In search of a course design and teaching methods to improve critical thinking skills.

This article describes a unique course design to teach critical thinking skills to students in formal academic degree programs preparing to become healthcare administrators. The course and its experimental design were motivated by several factors. First, intelligent and competent problem solving and decision making, most would agree, are directly dependent on critical thinking proficiency. Therefore, elevating students' critical-thinking competence will inherently improve their problem-solving and decision-making ability. Second, problem solving and decision making consumes the majority of an administrator's time. And finally, a review of AUPHA's catalog descriptions of healthcare graduate curriculums listrelatively few critical-thinking courses compared to the time administrators devote to it.

Risk adjustment for pediatric quality indicators.

The movement to measure medical care quality has been accelerating, spurred on by evidence of poor quality of care and trials of interventions to improve care. Appropriate measurement of quality of care is an essential aspect of improving the quality of care, yet some quality measures may be influenced by patients' attributes unrelated to quality of care. Risk adjustment is the term commonly applied to those methods that account for patient-related attributes, making measurement of health care quality as comparable as possible across providers or organizations seeing different mixes of patients. The measurement of quality of care for children poses specific challenges. In addition to these measurement challenges, analysts must ensure that quality comparisons among doctors, groups of doctors, hospitals, or health plans are not adversely affected by the likelihood that different types of patients seek care in different places. Although some techniques designed to adjust performance measures for case mix were developed for both adults and children, other systems are specific to childhood circumstances. The theoretical issues involved in risk-adjusting childhood outcomes measures for newborns in the neonatal intensive care unit were reviewed recently. Here, we go beyond the neonatal intensive care unit setting to consider risk adjustment for pediatric quality measures more broadly. In particular, we 1) review the conceptual background for risk-adjusting quality measures, 2) present policy issues related to adjusting pediatric quality measures, and 3) catalog existing risk-adjustment methodologies for pediatric quality measures. We conclude with an overall assessment of the status of risk adjustment for pediatric quality measures and recommendations for additional research and application.

Two-dimensional electrophoresis of urine specimens from patients with renal disease.

In an effort to develop non-invasive markers capable of characterizing renal disease with greater sensitivity and specificity than those currently available, urinary proteins were studied by high-resolution two-dimensional electrophoresis in order to catalog those proteins which appeared to be most affected by a variety of renal diseases. Urine specimens were prepared by high-pressure liquid chromatography and subjected to two-dimensional gel electrophoresis. Proteins were visualized with silver stain. Gels from 17 patients were analyzed in detail and compared to standard maps of human urinary proteins and plasma. The two-dimensional gels displayed approximately 100 times the number of proteins demonstrated by high resolution agarose electrophoresis. We have identified 34 proteins whose urinary concentrations were most affected by renal disease. Twenty seven were of plasma origin, based upon comigration with plasma samples (17 of unknown identity and function). Seven proteins were observed in normal urine but not present in plasma. These proteins, which may represent kidney tissue proteins, were not apparent in the urine of patients with proteinuria, most likely due to dilutional effects.

Collaborative study for establishment of a global standard for the potency assay of human anti-D immunoglobulin.

An international collaborative study aimed at establishing a global standard for the potency assay of anti-D immunoglobulin was started in 2002. 25 laboratories participated in this study run under the common aegis of the World Health Organization, the United States Food and Drug Administration (US-FDA) and the European Directorate for the Quality of Medicines (EDQM). The potencies of three candidate materials and the US-FDA standard (lot 3) included for comparison were evaluated using AutoAnalyzer, competitive enzyme-linked immunoassay (competitive EIA), flow cytometric methods or own "in-house" methods. Critical reagent, standardised procedures and standardised assay design were provided for either method, where appropriate. Central statistical evaluation of the potency data submitted by the participants was performed using a parallel line model. Agreement between laboratories and assay methods for all samples was observed. Intra-laboratory variability was lowest for laboratories performing flow cytometry and highest for laboratories that performed their in-house methods. Inter-laboratory variability was acceptable for all samples when assayed by AutoAnalyzer, competitive (EIA) and flow cytometric methods. It was concluded that sample A is most suitable to serve as a global standard and that sample C could serve as a reserve European Pharmacopoeia (Ph. Eur.) Biological Reference Preparation (BRP) batch provided that suitable stability is demonstrated. Sample A was adopted by the Ph. Eur. Commission at its 115th session (March 2003) as the first Ph. Eur. BRP (available from the EDQM: catalog number Y0000219) with the assigned potency of 285 IU/ampoule.

[Identification and registration of corn genotypes using molecular markers].

In plant genetics and breeding, second-generation molecular markers allow detailed characterization of plant genotypes. Unique genotypes at ten simple sequence repeat (SSR) loci were established for 40 maize accessions by means of PCR. For every locus, SSR analysis revealed heterozygotes among simple hybrids, which made it possible to identify the parental forms with a high probability of exclusion of nonparental forms. A system was proposed for registration of maize genotypes in the form of genetic formulas reflecting the allelic state of microsatellite loci, in order to catalog, preserve, and effectively employ the existing maize gene pool in breeding.
