A database for Chinese outpatients with rheumatic diseases.

Although several databases have been developed in rheumatology aimed at profiling the morbidity pattern of rheumatic diseases, or to capture the detailed clinical and outcome information of patients with a specific rheumatic disease, there is no database in China, as yet, for capturing visit-related health information of all outpatients with rheumatic diseases. In this project, a relational database was developed for the rheumatic outpatient clinic of Peking Union Medical College Hospital (PUMCH). The primary goal of this database is to collect and organize visit-related information of outpatients with rheumatic diseases to meet information needs of clinical research, health care continuity and teaching of rheumatic diseases. The implementation of this database can improve health services, medical records management and clinical research of outpatients with rheumatic disease at PUMCH.

A comparison of the recording of 30 common childhood conditions in the Doctor's Independent Network and General Practice Research Databases.

In this article we compare the recording of 30 common childhood conditions in two general practice databases of anonymised computerised medical records based on fundamentally different systems--the Doctor's Independent Network (DIN) database (Torex system) and the General Practice Research Database (GPRD) (In Practice Systems). Analysing the records of all children born 1990-1993 and followed for 5 years we found comparable results for most conditions, but differences between the hierarchical structures of the diagnostic coding systems (Read in DIN, OXMIS in GPRD) led to some differences between the databases. Practice variation was marked, but comparable between databases. Variation was greatest in conditions that are poorly defined clinically.

[Database on natural and transgenic luminous microorganisms: "BiolumBase"].

The database "BiolumBase" is designed for the selection and systematization of available world information on microorganisms containing bioluminescent systems; it includes two sections: "natural" and "transgenic" luminous microorganisms. At present, logic schemes of divisions, classification of the objects, presentation of characteristics, and the inputs of relative information, as well as the necessary program modules including links to the database, are developed. The database is constructed on the basis of published data and our own experimental results; the subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only the catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with lux genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Electronic asthma action plan database: asthma action plan development using Microsoft Access.

We created a user-friendly database for use with asthma management consistent with the national guidelines for asthma. A database was designed by using Microsoft Access for the creation of asthma action plans that can be shared between providers caring for patients with asthma. This database and the use of "form entry" improved documentation of asthma action plans, which are increasingly being used to assess appropriateness of care. We currently have 400 asthma action plans in the database. These action plans can be queried to document compliance with accepted best practices. Asthma action plans can be created and stored in an Access database that is both user-friendly and that can be networked to provide more consistent asthma care.

Design of a Multi Dimensional Database for the Archimed DataWarehouse.

The Archimed data warehouse project started in 1993 at the Geneva University Hospital. It has progressively integrated seven data marts (or domains of activity) archiving medical data such as Admission/Discharge/Transfer (ADT) data, laboratory results, radiology exams, diagnoses, and procedure codes. The objective of the Archimed data warehouse is to facilitate the access to an integrated and coherent view of patient medical in order to support analytical activities such as medical statistics, clinical studies, retrieval of similar cases and data mining processes. This paper discusses three principal design aspects relative to the conception of the database of the data warehouse: 1) the granularity of the database, which refers to the level of detail or summarization of data, 2) the database model and architecture, describing how data will be presented to end users and how new data is integrated, 3) the life cycle of the database, in order to ensure long term scalability of the environment. Both, the organization of patient medical data using a standardized elementary fact representation and the use of the multi dimensional model have proved to be powerful design tools to integrate data coming from the multiple heterogeneous database systems part of the transactional Hospital Information System (HIS). Concurrently, the building of the data warehouse in an incremental way has helped to control the evolution of the data content. These three design aspects bring clarity and performance regarding data access. They also provide long term scalability to the system and resilience to further changes that may occur in source systems feeding the data warehouse.

Medical Facts File: a self service database of reference information.

The Dahlgren Memorial Library, Georgetown University Medical Center, will demonstrate Medical Facts File, a newly developed in-house database of general medical information. The file content emerged from the library's experience with commonly asked reference questions and the need to develop a database as an online source for users seeking quick answers to medical queries. Medical Facts File joins a growing family of over 18 databases which comprise Georgetown's IAIMS Knowledge Network. Use scenarios will demonstrate how an online search is initiated, either directly or as a prompt from one of the other online databases. The design of Medical Facts File at the Dahlgren Memorial Library began in late 1989 with a publishing section on instructions for authors planning to submit manuscripts to a variety of prominent medical journals. Since then, seven sections have been identified for the database. Three sections are highlighted for presentation, although work on the project is on-going. Medical Facts File is an easy-to-use, time saving system that facilitates tedious searching through a multitude of library sources. It provides users with a self-service, information look-up system.

GenoMycDB: a database for comparative analysis of mycobacterial genes and genomes.

Several databases and computational tools have been created with the aim of organizing, integrating and analyzing the wealth of information generated by large-scale sequencing projects of mycobacterial genomes and those of other organisms. However, with very few exceptions, these databases and tools do not allow for massive and/or dynamic comparison of these data. GenoMycDB (http://www.dbbm.fiocruz.br/GenoMycDB) is a relational database built for large-scale comparative analyses of completely sequenced mycobacterial genomes, based on their predicted protein content. Its central structure is composed of the results obtained after pair-wise sequence alignments among all the predicted proteins coded by the genomes of six mycobacteria: Mycobacterium tuberculosis (strains H37Rv and CDC1551), M. bovis AF2122/97, M. avium subsp. paratuberculosis K10, M. leprae TN, and M. smegmatis MC2 155. The database stores the computed similarity parameters of every aligned pair, providing for each protein sequence the predicted subcellular localization, the assigned cluster of orthologous groups, the features of the corresponding gene, and links to several important databases. Tables containing pairs or groups of potential homologs between selected species/strains can be produced dynamically by user-defined criteria, based on one or multiple sequence similarity parameters. In addition, searches can be restricted according to the predicted subcellular localization of the protein, the DNA strand of the corresponding gene and/or the description of the protein. Massive data search and/or retrieval are available, and different ways of exporting the result are offered. GenoMycDB provides an on-line resource for the functional classification of mycobacterial proteins as well as for the analysis of genome structure, organization, and evolution.

SMS: sequence, motif and structure--a database on the structural rigidity of peptide fragments in non-redundant proteins.

Structure prediction methods aim to identify the relationship between the amino acid sequence of an unknown protein and information comprised in databases of known protein structures. Towards this end, we created a database by combining the amino acid sequences and the corresponding three-dimensional atomic coordinates for all the 25% non-redundant protein chains available in the Protein Data Bank. It contains information about the peptide fragments that are 5 to 10 residues long. In addition, options are provided for the users to visualize the individual motifs and the superposed fragments in the client machine. Further, useful functionalities areprovided to look for similar sequence motifs in all the sequence databases like PDB, 90% non-redundant protein chains, Genome database, PIR and Swiss-Prot. The database is being updated at regular intervals and the same can be accessed over the World Wide Web interface at the following URL: http://pranag.physics.iisc.ernet.in/sms/.

Establishment of an isoflavone database for usual Korean foods and evaluation of isoflavone intake among Korean children.

Asian populations including Koreans are assumed to have a higher isoflavone intake due to the higher consumption of soybean. However, it is difficult to estimate isoflavone intake because there is no isoflavone database in Korea. In this study, an isoflavone database was established with systematic review. Literature with analytical values of Korean soybeans and its products were collected and evaluated to establish an isoflavone database. A total of 142 food items containing isoflavones were selected among 2,932 food items in the Korean Nutrient Database. Among these, only 25 food items were evaluated with analytical values and the remaining 98 items were replaced with adaptations or calculations from similar items. Dietary intake of isoflavones was assessed for 426 boys and 365 girls aged 8 to 11 years with 3-day food records. The daily mean isoflavone intake was 8.3 mg among boys and 7.2 mg among girls. More than 70% of subjects had a daily isoflavone intake below 10 mg. The most contributory food item to the isoflavone intake among adolescents was tofu in quantity and soybean sauce in frequency. This database could be used to estimate isoflavone intakes from dietary data among various populations and to evaluate the relationships between isoflavone intake and chronic disease.

Modeling uncertainty in a database for physical gene mapping data.

We are building a database for the storage, retrieval, and graphical display of physical gene mapping data. To allow this information to be analyzed robustly, such a database must confront the inherent uncertainty of the data as a central design issue. The paper describes the overall database design, the types of gene mapping data which the system will contain, the types of uncertainty in the data, and certain of the design issues involved in allowing the database to handle uncertainty in a comprehensive fashion. Only if a full appreciation of uncertainty is built into the system from its inception will a physical gene mapping database be truly robust and successful.

A dedicated database program for cataloging recombinant clones and other laboratory products of molecular biology technology.

A novel computer database program dedicated to storing, cataloging, and accessing information about recombinant clones and libraries has been developed for the IBM (or compatible) personal computer. This program, named CLONES, also stores information about bacterial strains and plasmid and bacteriophage vectors used in molecular biology. The advantages of this method are improved organization of data, fast and easy assimilation of new data, automatic association of new data with existing data, and rapid retrieval of desired records using search criteria specified by the user. Individual records are indexed in the database using B-trees, which automatically index new entries and expedite later access. The use of multiple windows, pull-down menus, scrolling pick-lists, and field-input techniques make the program intuitive to understand and easy to use. Daughter databases can be created to include all records of a particular type, or only those records matching user-specified search criteria. Separate databases can also be merged into a larger database. This computer program provides an easy-to-use and accurate means to organize, maintain, access, and share information about recombinant clones and other laboratory products of molecular biology technology.

In a changing world: database to keep the pace.

A database to manage health care information can be an especially useful tool for the CNS. Systematic management of information is important in the multifaceted role characteristic of the CNS's scope of practice. The CNS not only provides theoretically sound creative care to patients and serves as a role model to nursing staff, but also monitors and substantiates the quality and effectiveness of care delivered. To do this, the CNS participates in research activities and synthesizes and uses research findings. These aspects of professional practice require collection and analysis of information that could be facilitated by the use of a database. The purposes of this article are to introduce some basic concepts of database and its relevance and contribution to the CNS, discuss issues inherent in setting up a database, and provide guidelines for CNSs who are considering using a database in their clinical practice.

The assessment of frequency estimates of Hae III-generated VNTR profiles in various reference databases.

The likelihood of occurrence of 1964 Hae III-generated target DNA profiles was estimated using fixed bin frequencies from various regional and ethnic databases and the multiplication rule. The databases generally were from the following major categories: Black, Caucasian, Hispanic, Oriental, and American Indian. It was found that subdivision, either by ethnic group or by U.S. geographic region, within a major population group did not substantially affect forensic estimates of the likelihood of occurrence of a DNA profile. As expected, the greatest variation in estimates for within-group estimates was among American Indian databases. Because the greatest variation in statistical estimates occurs across-major population groups, in most cases, there will be no unfair bias applying general population database estimates. Therefore, based on empirical data, there is no demonstrable need for using alternate approaches, such as the ceiling approach, to derive statistical estimates. The current practice of using general population databases and the multiplication rule provides valid estimates of the likelihood of occurrence of a DNA profile.

A reassessment of frequency estimates of PvuII-generated VNTR profiles in a Finnish, an Italian, and a general U.S. Caucasian database: no evidence for ethnic subgroups affecting forensic estimates.

Recently, Krane et al. addressed the effect of estimating various target DNA profile frequencies in Finnish, Italian, and general U.S. Caucasian databases. They observed that, when using an "inappropriate ethnic," or noncognate, database (e.g., a Finnish target profile frequency estimated in an Italian database, and vice versa), estimates were less common than when the target profile frequencies were estimated using their own ethnic, or cognate, database, and these estimates differed by more than one order of magnitude. These differences were attributed to the effects of subgroups. We demonstrate that the differences can be ascribed to statistical artifacts that induce large biases and correlations. Additionally, we show that the differences of estimates of any specific DNA profile frequency based on allelic size frequencies from different databases become smaller when the fixed-bin rather than a +/- 2.5% floating-bin approach is used.

OWL--a non-redundant composite protein sequence database.

A comprehensive, non-redundant composite protein sequence database is described. The database, OWL, is an amalgam of data from six publicly-available primary sources, and is generated using strict redundancy criteria. The database is updated monthly and its size has increased almost eight-fold in the last six years: the current version contains > 76,000 entries. For added flexibility, OWL is distributed with a tailor-made query language, together with a number of programs for database exploration, information retrieval and sequence analysis, which together form an integrated database and software resource for protein sequences.

The HSSP database of protein structure-sequence alignments.

HSSP (homology-derived structures of proteins) is a derived database merging structural (2-D and 3-D) and sequence information (1-D). For each protein of known 3D structure from the Protein Data Bank, the database has a file with all sequence homologues, properly aligned to the PDB protein. Homologues are very likely to have the same 3D structure as the PDB protein to which they have been aligned. As a result, the database is not only a database of sequence aligned sequence families, but it is also a database of implied secondary and tertiary structures.

An object model for uniform access to heterogeneous databases.

The vast amount of patient information collected and maintained by hospitals is seldom stored in a single database. Much programming effort is wasted on formulating specific queries for each of several data sources, rather than focusing attention on developing the intended functionality of the application. This problem becomes more apparent as more data sources become available. The most obvious strategy for dealing with this multiplicity of data sources, namely storing all data in a single database, is impractical for reasons such as security and administrative control. This paper describes one possible solution to managing access to several database systems within applications. Using object-oriented techniques, the solution identifies the commonality among database management systems and provides a uniform method of communication between applications and databases. We describe a C(++)-based implementation which embodies these concepts.

Database access and problem solving in the basic sciences.

This study examined the potential contribution that access to a database of biomedical information may offer in support of problem-solving exercises when personal knowledge is inadequate. Thirty-six medical students were assessed over four occasions and three domains in the basic sciences: bacteriology, pharmacology, and toxicology. Each assessment consisted of a two-pass protocol in which students were first assessed for their personal knowledge of a domain with a short-answer problem set. Then, for a sample of problems they had missed, they were asked to use a database, INQUIRER, to respond to questions which they had been unable to address with their personal knowledge. Results indicate that for a domain in which the database is well-integrated in course activities, useful retrieval of information which augmented personal knowledge increased over three assessment occasions, even continuing to increase several months after course exposure and experience with the database. For all domains, even at assessments prior to course exposure, students were able to moderately extend their ability to solve problems through access to the INQUIRER database.
