This metric helps to standardize, objectify, quantify, and even automate light microscopy observations. Our new algorithm uses this metric to automatically identify and annotate a donut shaped actomyosin stress fiber bundle evident in vascular smooth muscle cells on certain types of surfaces. Both the metric and the algorithm have been implemented as an open source plugin for the popular ImageJ toolkit. They are available for download at http://code.google.com/p/actin-myosin-plugin/. Using cells stained for the cytoskeletal proteins actin and myosin, we show how characteristics of the identified stress fiber bundle are indicative of the kind of surface the cell is placed upon, and prove that weak spots in this structure are correlated with local membrane extensions. Given the relationship between membrane extension, cell migration, vascular disease, embryonic development, and cancer metastasis we provide that these tools to enable biological research that could improve our quality of life.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

These terms are instinctively supplied by the users, and hence, different users often use different terms to describe the same clinical concept. This term diversity makes future database integration and analysis a huge challenge. In this paper, we study the problem of standardization of the terms used in a specific kind of user-designed artifact, the encounter forms or templates, using a popular clinical terminology, the SNOMED CT.\u0000 In particular, we focus on the problem of mapping the terms on an encounter form to SNOMED CT concepts. Existing term mapping techniques are solely based on syntactic string similarity. Such techniques are unable to disambiguate among the terms that resemble one another linguistically, and yet differ semantically. To improve existing techniques, we consider the context of a term in the mapping process and propose a hybrid approach relying on linguistics as well as structural information. For a given form term, this approach (i) exploits the semantic structure of the form to derive the term's context, and (ii) maps the term to a linguistically- matching SNOMED CT concept that is compatible with the derived context. We test the approach on over 900 clinician-specified terms used in 26 forms. This method achieves 23% improvement in precision and 38% improvement in recall, over a pure linguistic-based approach. Our first contribution is that we introduce and address a new problem of mapping form terms to standard concepts. The second contribution is that the experimental evaluation confirms that structural information has a major role in improving mapping performance, and in addressing the key challenges associated with semantic mapping.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

This data deluge has motivated the development of machine learning and data mining technologies to facilitate efficient biomedical research. Despite the obvious labor-saving potential of these technologies and the concomitant academic interest therein, however, adoption of machine learning techniques by medical researchers has been relatively sluggish. One explanation for this is that while many machine learning methods have been proposed and retrospectively evaluated, they are rarely (if ever) actually made accessible to the practitioners whom they would benefit. In this work, we describe the ongoing development of an end-to-end interactive machine learning system at the Tufts Evidence-based Practice Center. More specifically, we have developed abstrackr, an online tool for the task of citation screening for systematic reviews. This tool provides an interface to our machine learning methods. The main aim of this work is to provide a case study in deploying cutting-edge machine learning methods that will actually be used by experts in a clinical research setting.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

They centralize the management, maintenance and purchasing of medical equipment. They are being embraced and developed by some hospitals, and considered by others. Hence, there is a growing need to understand MEL practice and design. This paper compares three MELs through interviews and observations of everyday practice using DiCoT (Distributed Cognition for Teamwork) as a method for multisite comparison. This is a novel use of the method that reveals general issues and best practices across contexts. Our results complement the little formal information that is available on MELs, and explores the workings of the library as a socio-technical system. As far as we are aware no empirical studies have been published in this area. We conclude with design opportunities and requirements for MELs, and propose DiCoT as an effective way to compare socio-technical systems, including revealing issues and best practices in other clinical contexts more broadly.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

In contrast, serendipity is a natural part of human information seeking process that can lead to unexpected and useful discoveries. It appears both serendipity and personalization are important. However, it remains unclear how these modes of interaction impact content retrieval and consumption. To empirically analyze the influence of personalization and serendipity on information retrieval, a medical news information system named MedSIFTER was developed. The system can personalize the presentation of news articles based on users' interest profiles. Using a control variable, built into the system, MeSIFTER's personalization level can be modulated, ranging from high to low (or zero). In this study, based on MedlinePlus as main information source, three different system modalities were compared (zero, low, and high levels of personalization). The experimental analysis engaged three different user groups, over a four week period. Strong evidence of serendipity was found across all three user groups, independent of the level of personalization. Users also appeared to be uniformly satisfied regardless of the level of personalization.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...
