The evolving role of information technology in the drug discovery process.

Information technologies for chemical structure prediction, heterogeneous database access, pattern discovery, and systems and molecular modeling have evolved to become core components of the modern drug discovery process. As this evolution continues, the balance between in silico modeling and 'wet' chemistry will continue to shift and it might eventually be possible to step through the discovery pipeline without the aid of traditional laboratory techniques. Rapid advances in the industrialization of gene sequencing combined with databases of protein sequence and structure have created a target-rich but lead-poor environment. During the next decade, newer information technologies that facilitate the molecular modeling of drug-target interactions are likely to shift this balance towards molecular-based personalized medicine -- the ultimate goal of the drug discovery process.

Design and implementation of a web-based HL7 message generation and validation system.

Health level 7 (HL7) is the standard of electronic data interchange in the health domain. We have developed a web-based message generation and validation system for testing the message format of the data exchange among hospitals and health organizations. Compared with other existing ones, this system has incorporated several novel functions that optimize medical data exchange and helps medical students in learning HL7 messages. When receiving HL7 message from another system with the hypertext transmission protocol or accepting an uploaded HL7 message file, the system shows the validation result through a web browser. In this platform, users may input and edit medical data on-line to test and generate standard HL7 messages. The system supports various data formats and is capable of transforming HL7 messages between the standard delimiter format and the extensible markup language format. This system has been successfully passed our system evaluation among 139 student users for HL7 training. Most of the users agreed that the system is helpful for medical data exchange.

Application of fuzzy functions for visual presentation of medical data.

While interpretation of medical data is very often an ambiguous process, computers usually display results of recommendations, provided by both human experts and computer algorithms, as concrete data. This study proposes a visual presentation of relative degrees of uncertainty along with "standard" concrete medical data. A medical parameter (mean arterial pressure) is dynamically evaluated during surgery for being too low or too high. Fuzzy membership functions are utilized to display degrees of deviation in the form of a clear and concise pie chart. Thus, in the Operating Room the anesthesiologist can be provided with an easy statistical assessment of uncertainty of existing recommendations.

A framework to identify learning needs for continuing nurse education using information technology.

This paper concerns one of the main problems facing continuing nurse education, that of matching the learning needs of the individual nurse with the needs of the care setting. This endeavour is inescapable because of the necessity for giving high quality care within financial restraint. Modern information technology, it is suggested, can be helpful in fulfilling the task more easily. A theoretical framework is introduced as a possible solution for developing a computer program which, it is the hope of the author, will be available in the not so far future.

Building a virtual cancer research organization.

BACKGROUND: The Cancer Research Network (CRN) comprises the National Cancer Institute and 11 nonprofit research centers affiliated with integrated health care delivery systems. The CRN, a public/private partnership, fosters multisite collaborative research on cancer prevention, screening, treatment, survival, and palliation in diverse populations. METHODS: The CRN's success hinges on producing innovative cancer research that likely would not have been developed by scientists working individually, and then translating those findings into clinical practice within multiple population laboratories. The CRN is a collaborative virtual research organization characterized by user-defined sharing among scientists and health care providers of data files as well as direct access to researchers, computers, software, data, research participants, and other resources. The CRN's research management Web site fosters a high-functioning virtual scientific community by publishing standardized data definitions, file specifications, and computer programs to support merging and analyzing data from multiple health care systems. RESULTS: Seven major types of standardized data files developed to date include demographics, health plan eligibility, tumor registry, inpatient and ambulatory utilization, medication dispensing, laboratory tests, and imaging procedures; more will follow. Data standardization avoids rework, increases multisite data integrity, increases data security, generates shorter times from initial proposal concept to submission, and stimulates more frequent collaborations among scientists across multiple institutions. CONCLUSIONS: The CRN research management Web site and associated standardized data files and procedures represent a quasi-public resource, and the CRN stands ready to collaborate with researchers from outside institutions in developing and conducting innovative public domain research.

Evaluation of a computer interview system for use with neuro-otology patients.

The effectiveness, feasibility and credibility of a computer assessment package was evaluated in a group of 60 neuro-otological outpatients. The computer system was compared with a standard questionnaire and used to elicit basic neuro-otological information prior to clinical interview. The majority of patients (81%) preferred computer assessment. There were no differences in attitude or difficulties between diagnostic groups. Older patients had more difficulties and took longer than younger patients. The computer system was also more efficient than the form from an information handling and administrative point of view.

Cyberinfrastructure: empowering a "third way" in biomedical research.

Biomedicine has experienced explosive growth, fueled in parts by the substantial increase of government support, continued development of the biotechnology industry, and the increasing adoption of molecular-based medicine. At its core, it is composed of fiercely independent, innovative, entrepreneurial individuals, organizations, and institutions. The field has developed unprecedented capacity to characterize biologic systems at their most fundamental levels with the use of tools and technologies almost unimaginable a generation ago. Biomedicine is at the precipice of unlocking the very essence of biologic life and enabling a new generation of medicine. Development and deployment of cyberinfrastructure may prove to be on the critical path to obtaining these goals.

Guide to the Internet. The world wide web.

The world wide web provides a uniform, user friendly interface to the Internet. Web pages can contain text and pictures and are interconnected by hypertext links. The addresses of web pages are recorded as uniform resource locators (URLs), transmitted by hypertext transfer protocol (HTTP), and written in hypertext markup language (HTML). Programs that allow you to use the web are available for most operating systems. Powerful on line search engines make it relatively easy to find information on the web. Browsing through the web--"net surfing"--is both easy and enjoyable. Contributing to the web is not difficult, and the web opens up new possibilities for electronic publishing and electronic journals.

Reliability of health information for the public on the World Wide Web: systematic survey of advice on managing fever in children at home.

OBJECTIVE: To assess the reliability of healthcare information on the world wide web and therefore how it may help lay people cope with common health problems. METHODS: Systematic search by means of two search engines, Yahoo and Excite, of parent oriented web pages relating to home management of feverish children. Reliability of information on the web sites was checked by comparison with published guidelines. MAIN OUTCOME MEASURES: Minimum temperature of child that should be considered as fever, optimal sites for measuring temperature, pharmacological and physical treatment of fever, conditions that may warrant a doctor's visit. RESULTS: 41 web pages were retrieved and considered. 28 web pages gave a temperature above which a child is feverish; 26 pages indicated the optimal site for taking temperature, most recommending rectal measurement; 31 of the 34 pages that mentioned drug treatment recommended paracetamol as an antipyretic; 38 pages recommended non-drug measures, most commonly tepid sponging, dressing lightly, and increasing fluid intake; and 36 pages gave some indication of when a doctor should be called. Only four web pages adhered closely to the main recommendations in the guidelines. The largest deviations were in sponging procedures and how to take a child's temperature, whereas there was a general agreement in the use of paracetamol. CONCLUSIONS: Only a few web sites provided complete and accurate information for this common and widely discussed condition. This suggests an urgent need to check public oriented healthcare information on the internet for accuracy, completeness, and consistency.
