Design and evaluation of an ontology based information extraction system for radiological reports

Cataloged from PDF version of article.This paper describes an information extraction system that extracts and converts the available information in free text Turkish radiology reports into a structured information model using manually created extraction rules and domain ontology. The ontology provides flexibility in the design of extraction rules, and determines the information model for the extracted semantic information. Although our information extraction system mainly concentrates on abdominal radiology reports, the system can be used in another field of medicine by adapting its ontology and extraction rule set. We achieved very high precision and recall results during the evaluation of the developed system with unseen radiology reports. (C) 2010 Elsevier Ltd. All rights reserved

A behaviour changing syringe : making invisible risk, visible to deter the reuse of syringes in a curative context

Medical devices are a core component of health systems, and thus required for achieving universal health coverage, and have been recognized as indispensable for health care provision in the World Health As-sembly resolution, on health technologies (WHA60.29) in 2007. These health technologies are required in screening, prevention, diagnosis, treatment, rehabilitation and palliative care, but their safe use, rational selection, assessment, effective regulation and innovation remain a very complicated challenge in all set-tings, due to the enormous diversity, lack of availability, quality, safety, appropriateness and affordability, particularly in low-resource settings. Therefore, even if important awareness has been raised in the last few years, patients still lack access to priority medical devices and thus much work has to be done by health professionals, governments, academia and industry, among many others. Following the resolution of 2007, the priority medical devices report and the success of the First WHO Global Forum on Medical Devices in Thailand in 2010, WHO became highly committed to the important work related to medical devices. New WHO tools and publications were developed and disseminated to increase awareness in the field in ministries of health, industry and academia. Several workshops and continuous capacity building in various countries and regions led to a high demand from medical device stakeholders, for a second global forum that would follow-up and expand on the topics and recommenda-tions presented previously. Accordingly, in August 2013, WHO determined to convene a Second Global Forum on Medical Devices to take place in Geneva, Switzerland, on 22-24 November 2013. The objectives of the Forum were to: (i) define methods of increasing access to priority medical devices under the Universal Health Coverage initiative; (ii) share evidence on best practices in health technology assessment, management and regulation of medical devices; (iii) demonstrate the development and use of appropriate and innovative technologies that respond to global health priorities; and (iv) present the outcomes of the implementation of the World Health Assembly resolution on health technologies (WHA60.29) and the status of actions resulting from the First Global Forum on Medical Devices..

Design and implementation of a radiological image viewing tool

Ankara : Department of Computer Engineering and Information Science and Institute of Engineering and Science, Bilkent Univ., 1993.Thesis (Master's) -- Bilkent University, 1993.Includes bibliographical references leaves 57-58Recent developments in Picture Archiving and Communication Systems (PACS) in clinical environment allow physicians and radiologists to access and assess radiographic images directly through imaging workstations. In this thesis, an imaging workstation called RADVIEW^ has been designed and implemented for using in a PACS environment in radiology departments of large hospitals. The main function of RADVIEVV is the archiving of and access to radiological images by maintaining user friendly interactive environment to radiologists. The system can provide rapid access to any or all radiological information associated with a patient.Keskin, GürhanM.S

Challenges resulting from simultaneous online education during the "Covid-19" pandemic: the case of King Khalid University, Saudi Arabia

The spread of the new Corona virus has led to the closure of direct educational activities and the transition to distance learning. Therefore, this study aimed to identify the effectiveness of distance learning in the shadow of the Coronavirus pandemic in Saudi Arabia. A qualitative study was conducted by distributing an electronic questionnaire to the college students to find out their opinions about distance learning. The statistical analysis program SPSS was used to obtain the results. The content analysis revealed the challenges that faced students at Karak University College, and the method of online learning was well received by them. All participants agreed that distance learning saves time and that its performance has improved due to increased time use. However, they indicated that they faced some challenges including methodology, content perception, technology, and behavioral challenges during the online courses and exams

Retrospective Analysis of a Breast Health Program on Routine Annual Mammography in Low-Income, Uninsured Women

Problem: Detection of breast cancer in women of low socioeconomic status, lacking health insurance, can be improved by increasing annual mammography rates, yet little is known about their screening behavior. Purpose: A retrospective subject-controlled study of an ongoing Breast Health Program, at a not-for-profit, non-government assisted, volunteer clinic, was undertaken to examine mammography usage and discovery variables. Design and Methods: English and Spanish speaking women 40 years old and over who viewed in a 7-minute breast health DVD and were offered free mammography were eligible for the study (N= 223). The Health Belief Model (HBM) (Becker, 1974) provided the study framework that utilized radiology billing records for mammography completion and a dual-language self-administered survey. Data retrieval was from March 2004 to July 2009, with DVD viewing beginning in December 2006. Recruitment occurred between July 2009 and September 2009. Results: Results revealed that 214 (96%) women had a mammography after viewing the DVD. Of the 120 subjects that had time to complete an annual mammography, 28 (23%) completed it in the 12th month, 48 (40%) completed it within 15 months, and 91 (75%) completed even if late. Only 37 subjects had time to complete a third mammography and of those only 8 completed a fourth. Significant findings found: (1) a greater proportion of women who received a reminder postcard participated in their annual mammography in the 12th month, Χ2(1) = 3.98, p = .046; (2) perceptions of breast cancer susceptibility scores were significantly lower (M = 6.89, SD = 3.18), in those who completed their annual mammography in the 12th month, t(118) = 2.03, p = .045; (3) a greater proportion of women who were knowledgeable about screening recommendations completed annual mammography, even if late, Χ2(1) = 4.736, p = .030 and; (4) Hispanic women completed at a significantly higher rate (n= 69; 81.2%) even if late, Χ2(2) = 6.450, p = .04. Implications: Longitudinal studies utilizing radiology billing records for mammography completion present real findings of mammography usage. This study\u27s findings enhance the understanding of low-income, working uninsured women and identify new variables not found in comparative research findings

Learning About the Information Seeking behavior of Allied Medical Sciences Students: Advices For Libraries of multidisciplinary Colleges

Libraries will have satisfactory performance in terms of providing services to users if they firstly identify the information needs of their clients and then, they seek to meet these needs. To accomplish this aim, identifying the information seeking behavior of users seems necessary. The aim of the present study was to evaluate the methods and motives of information seeking by students of allied medical sciences. The population of the study included the postgraduate students of Faculty of Allied Medical Sciences of Shahid Beheshti University of Medical Sciences accepted to the university in 2015 to 2016. The results indicated that the main motivations of students for the information seeking is first to update their professional knowledge and then to do research activities. Among the information channels used, formal channels have been given more attention. In rating the difficulties ahead in the searching for information, the lack of or unavailability of resources was identified as the most important factor. Providing more and better information on the electronic resources of the university for the graduate students could lead to the more efficient use of the existing resources and would have much success in achieving the educational and research goals. In addition, librarians need to have detailed and scientific knowledge about the information seeking behaviors of their users so that they can meet the information needs of them through providing the necessary facilities and resources using minimum time and the lowest cost

Foundation, Implementation and Evaluation of the MorphoSaurus System: Subword Indexing, Lexical Learning and Word Sense Disambiguation for Medical Cross-Language Information Retrieval

Im medizinischen Alltag, zu welchem viel Dokumentations- und Recherchearbeit gehört, ist mittlerweile der überwiegende Teil textuell kodierter Information elektronisch verfügbar. Hiermit kommt der Entwicklung leistungsfähiger Methoden zur effizienten Recherche eine vorrangige Bedeutung zu. Bewertet man die Nützlichkeit gängiger Textretrievalsysteme aus dem Blickwinkel der medizinischen Fachsprache, dann mangelt es ihnen an morphologischer Funktionalität (Flexion, Derivation und Komposition), lexikalisch-semantischer Funktionalität und der Fähigkeit zu einer sprachübergreifenden Analyse großer Dokumentenbestände. In der vorliegenden Promotionsschrift werden die theoretischen Grundlagen des MorphoSaurus-Systems (ein Akronym für Morphem-Thesaurus) behandelt. Dessen methodischer Kern stellt ein um Morpheme der medizinischen Fach- und Laiensprache gruppierter Thesaurus dar, dessen Einträge mittels semantischer Relationen sprachübergreifend verknüpft sind. Darauf aufbauend wird ein Verfahren vorgestellt, welches (komplexe) Wörter in Morpheme segmentiert, die durch sprachunabhängige, konzeptklassenartige Symbole ersetzt werden. Die resultierende Repräsentation ist die Basis für das sprachübergreifende, morphemorientierte Textretrieval. Neben der Kerntechnologie wird eine Methode zur automatischen Akquise von Lexikoneinträgen vorgestellt, wodurch bestehende Morphemlexika um weitere Sprachen ergänzt werden. Die Berücksichtigung sprachübergreifender Phänomene führt im Anschluss zu einem neuartigen Verfahren zur Auflösung von semantischen Ambiguitäten. Die Leistungsfähigkeit des morphemorientierten Textretrievals wird im Rahmen umfangreicher, standardisierter Evaluationen empirisch getestet und gängigen Herangehensweisen gegenübergestellt
