On October 16, 2007, the US Food and Drug Administration (FDA) approved raltegravir for treatment of human immunodeficiency virus (HIV)-1 infection in combination with other antiretroviral agents in treatment-experienced adult patients who have evidence of viral replication and HIV-1 strains resistant to multiple antiretroviral agents. Raltegravir is first(More)
H uman immunodeficiency virus (HIV)–infected individuals are living longer in the era of antiretroviral therapy. As a result, they are increasingly prone to the development of concomitant chronic disease. Coronary heart disease (CHD) is the leading cause of death in the United States and Europe. Recent studies suggest that CHD rates may be increasing among(More)
BACKGROUND The U.S. government has licensed SNOMED CT to permit broad-based evaluation and use of the terminology. We evaluated the ability of SNOMED CT to represent terms used for interface objects (e.g., labels and captions) and concepts used for data and branching logic in a general medical evaluation template in use within the Department of Veterans(More)
The current United States Health Information Technology Standards Panel's interoperability specification for biosurveillance relies heavily on chief complaint data for tracking rates of cases compatible with a case definition for diseases of interest (e.g. Avian Flu). We looked at SNOMED CT to determine how well this large general medical ontology could(More)
Viral encephalitis is worldwide spread pathology with high morbidity and mortality. Its incidence is higher in children. Enteroviruses, varicella zoster virus and herpes simplex viruses are the most frequent agents. However, in spite of the use of modern microbiological and radiological methods, an etiological diagnosis is reached in less than 50% of cases,(More)
In 2014, the World Health Organization (WHO) developed the End TB Strategy in response to a World Health Assembly Resolution requesting Member States to end the worldwide epidemic of tuberculosis (TB) by 2035. For the strategy's objectives to be realised, the next 20 years will need novel solutions to address the challenges posed by TB to health(More)
BACKGROUND Antiretroviral therapy for HIV-1 infection has become increasingly complex. The availability of new and potent drugs and progress in understanding the pathogenesis of HIV-1 infection have led to the establishment of new treatment paradigms. The varying dosing regimens, associated toxicities, and the potential for drug-drug and food-drug(More)
A 39-year-old male, who recently underwent a composite valve graft of the aortic root and ascending aorta for bicuspid aortic valve and aortic root aneurysm, was hospitalized for severe sepsis, rhabdomyolysis (creatine kinase 29000 U/L), and severe liver dysfunction (AST > 7000 U/L, ALT 4228 U/L, and INR > 10). Cardiac magnetic resonance imaging (MRI)(More)
Background: Clinical terminologies, like the domains they model, may change over time. Existing methods for identifying and characterizing terminology change, address individual concepts and their interrelationships rather than the overall structure of the terminology. Exposing high level terminology structure may improve developers' and users' ability to(More)
