We believe that a successful learning health care system will require both approaches, and we suggest a model that resolves this escalating tension: a "green button" function within EHRs to help clinicians leverage aggregate patient data for decision making at the point of care. A formal concept analysis and semantic query expansion cooperation to refine health outcomes of interest. Our Web log mining approach has the potential to monitor responses to FDA alerts at a national level. Callahan, Alison, Igor Pernek, Gregor Stiglic, Jure Leskovec, Howard R. Strasberg and Nigam H. Shah. Patient-level analyses suggest a clear separation between autism and the other disorders, while revealing significant overlap between schizophrenia and bipolar disorder. Our results suggest that metrics based on the ontology only may be preferable to information-content-based metrics, and point to the need for more research on validating the different approaches. We find that SDAs can attain reasonable predictive accuracy in signaling adverse events. We develop an explicit formal language from the language implicit in the Reactome data format and specify a logic to evaluate models expressed using this language. The BioPAX community standard for pathway data sharing. The duration of ADT use was also tested for association with Alzheimer's disease risk.There were 16,888 individuals with prostate cancer meeting all inclusion and exclusion criteria, with 2,397 (14.2%) receiving ADT during a median follow-up period of 2.7 years (interquartile range, 1.0-5.4 years). Here we describe a preliminary analysis of search logs from healthcare professionals as a source for detecting adverse drug events. We propose a complementary format to represent GO annotation files as knowledge bases using the W3C recommended Web Ontology Language (OWL). This simple format lacks the knowledge representation (KR) capabilities to represent unambiguously semantic relationships between each field. View details for Web of Science ID 000182694200009. B., Hinchcliff, M., Denny, J., Kaminski, N., Herazo-Maya, J. D., Shah, N. H., Khatri, P. Finding missed cases of familial hypercholesterolemia in health systems using machine learning. We have shown that the syntactic and frequency information is useful to identify errors in the Metathesaurus. Low, Y. S., Daugherty, A. C., Schroeder, E. A., Chen, W., Seto, T., Weber, S., Lim, M., Hastie, T., Mathur, M., Desai, M., Farrington, C., Radin, A. However, the cost of conducting these trials can be prohibitive. We compare and contrast the manual procedure with a fully automated approach using WordNet to quantify the degree of integration enabled by iterative curation and refinement of the PHARE ontology. document corpora annotated with corresponding semantic metadata (gold standards and training data), biomedical terminologies and ontologies providing domain-specific background knowledge at different levels of formality and specificity, software architectures for building complex and scalable text analytics pipelines and Web services grounded to them, as well as comprehensive ways to disseminate and interact with the typically huge amounts of semiformal knowledge structures extracted by text mining tools. Toward Automated Detection of Peripheral Artery Disease Using Electronic Health Records. Standard data mining algorithms can accurately and efficiently identify these outcomes in existing EHRs; the complete assessment of these outcomes is essential to move practice into the patient-centered realm of healthcare. The seven papers and the commentary selected for this supplement span a wide range of topics including: web-based querying over multiple ontologies, integration of data, annotating patent records, NCBO Web services, ontology developments for probabilistic reasoning and for physiological processes, and analysis of the progress of annotation and structural GO changes. The system processes the text metadata of diverse resource elements such as gene expression data sets, descriptions of radiology images, clinical-trial reports, and PubMed article abstracts to annotate and index them with concepts from appropriate ontologies. This experimentation emphasizes positive results for sensitivity and specificity measures. The trade-off between the speed and simplicity of dictionary-based term recognition and the richer linguistic information provided by more advanced natural language processing (NLP) is an area of active discussion in clinical informatics. The main outcome measure was presence of terms indicating allergy or allergy medications use overrepresented in juvenile idiopathic arthritis patients with chronic uveitis. StressDB uses Windows 2000 as the centralized database server with Oracle 8i as the relational database management system. This study compares the performance of 18 automatic confounder control methods.Methods include propensity scores, direct adjustment by machine learning, similarity matching and resampling in two simulated and one real-world EHR datasets.Direct adjustment by lasso regression and ensemble models involving multiple resamples have performance comparable to expert-based propensity scores and thus, may help provide real-time EHR-based evidence for timely clinical decisions.

The metric based only on the ontology structure correlated most with expert opinion. Randomized controlled trials have traditionally been the gold standard against which all other sources of clinical evidence are measured. Sitagliptin was the most effective second-line therapy, and as effective as metformin as a first line therapy. To validate our results, we evaluate our performance on a gold standard of 1698 DDIs curated from existing knowledge bases, as well as with signaling DDI associations directly from FAERS using established methods.Our method achieves good performance, as measured by our gold standard (area under the receiver operator characteristic (ROC) curve >80%), on two independent EHR datasets and the performance is comparable to that of signaling DDIs from FAERS. Musen, M. A., Noy, N. F., Shah, N. H., Whetzel, P. L., Chute, C. G., Story, M., Smith, B. Translational bioinformatics embraces big data. Therefore, analyzing patterns of off-label drug usage in the clinical setting is an important step toward reducing the incidence of adverse events and for improving patient safety. Recently, advances in clinical text processing and the increasing availability of clinical data have enabled analogous analyses on data from electronic medical records. Miner, A.

Syntactically, over 90% of matched terms were in noun phrases. The Annotator service has access to a large dictionary of biomedical terms derived from the United Medical Language System (UMLS) and NCBO ontologies. The papers span a wide range of topics including practical solutions for data and knowledge integration for translational medicine, hypothesis based querying , understanding kidney and urinary pathways, mining the pharmacogenomics literature; theoretical research into the orthogonality of biomedical ontologies, the representation of diseases, the representation of research hypotheses, the combination of ontologies and natural language processing for an annotation framework, the generation of textual definitions, and the discovery of gene interaction networks. While not as precise as manually curated terms, we find that the additional enriched concepts have value when coupled with traditional enrichment analyses using curated terms.Multiple ontologies have been developed for gene and protein annotation, by using a dataset of both manually curated GO terms and automatically recognized concepts from curated text we can expand the realm of hypotheses that can be discovered. Callahan, A., Winnenburg, R., Shah, N. H. Implementing Machine Learning in Health Care - Addressing Ethical Challenges, Performing an Informatics Consult: Methods and Challenges. Miner, A. S., Haque, A., Fries, J. This article surveys efforts on text mining of the pharmacogenomics literature, mainly from the period 2008 to 2011. An unsupervised learning method to identify reference intervals from a clinical database. For example, protein-protein interaction networks have been successfully used to identify candidate disease genes. These inputs are further processed into statistics used by a discriminative classifier which outputs the probability that a given drug-disorder pair represents a valid ADE association. This large amount of pathway data in a computable form will support visualization, analysis and biological discovery. Contributing to the national computing infrastructure, NCBO has developed BioPortal, a web portal that provides access to a library of biomedical ontologies and terminologies (http://bioportal.bioontology.org) via the NCBO Web services. Stanford, CA 94305-5479 BioPortal also enables integrated search of biomedical data resources such as the Gene Expression Omnibus (GEO), ClinicalTrials.gov, and ArrayExpress, through the annotation and indexing of these resources with ontologies in BioPortal.

Measure what matters: Counts of hospitalized patients are a better metric for health system capacity planning for a reopening. Semantic-similarity measures quantify concept similarities in a given ontology. We develop a method, LIMIT, to use laboratory test results from a clinical database to identify ICD9 codes that are associated with extreme laboratory results, thus automating the a posteriori method. Inference over OWL ontologies (for type specifications, subclass assertions and parthood relations) and retrieval of facts stored as Bio2RDF linked data provide support for a given hypothesis. It stars Aarti Patel, Raj Vazir, Satyam Sharma, Aashna Mehta & Saumya Shah in lead roles. This expansion means that researchers now face a hurdle to extracting the data they need from the large numbers of data that are available. The web application STOP is available at http://mooneygroup.org/stop/. Nigam has 3 jobs listed on their profile. Vashisht, R., Jung, ., Schuler, A., Banda, . These methods have broad application for quality improvement efforts in which events of interest occur outside of a network that allows for patient data sharing. This study introduces ontology-based annotation as a method to overcome this difficulty. These data provide an example of how a combination of experimental studies and data-mining approaches can be applied to prioritize drug safety signals for further investigation. We outline the methodology of enrichment analysis, the associated challenges, and discuss novel analyses enabled by RANSUM.
