OBJECTIVE We evaluate the feasibility and accuracy of existing point-of-care HIV tests performed by an untrained patient compared with the routinely used HIV point-of-care test offered to patients in 2 urban emergency departments (EDs). METHODS From April 2008 through December 2009, patients who had completed a standard HIV oral fluid test performed by a(More)
BACKGROUND We developed a practical influenza forecast model based on real-time, geographically focused, and easy to access data, designed to provide individual medical centers with advanced warning of the expected number of influenza cases, thus allowing for sufficient time to implement interventions. Secondly, we evaluated the effects of incorporating a(More)
Molecular diagnostics are revolutionising the clinical practice of infectious disease. Their effects will be significant in acute-care settings where timely and accurate diagnostic tools are critical for patient treatment decisions and outcomes. PCR is the most well-developed molecular technique up to now, and has a wide range of already fulfilled, and(More)
A rapid assay for eubacterial species identification is described using high-resolution melt analysis to characterize PCR products. Unique melt profiles generated from multiple hypervariable regions of the 16S rRNA gene for 100 clinically relevant bacterial pathogens, including category A and B biothreat agents and their surrogates, allowed highly specific(More)
The segregation of secretory proteins into the cisternae of the endoplasmic reticulum (ER) is normally tightly coupled to their synthesis. This feature distinguishes their biogenesis from that of proteins targeted to many other organelles. In the examples presented, translocation across the ER membrane is dissociated from translation. Transport, which is(More)
BACKGROUND  Google Flu Trends (GFT) is a novel Internet-based influenza surveillance system that uses search engine query data to estimate influenza activity and is available in near real time. This study assesses the temporal correlation of city GFT data to cases of influenza and standard crowding indices from an inner-city emergency department (ED). (More)
OBJECTIVE(S) : To determine the effect of viral suppression on cross-sectional incidence testing. METHODS : In 2001 and 2003, patients entering the Johns Hopkins Hospital (JHH) Emergency Department (ED) were enrolled into an interview-based identity-unlinked serosurvey. All HIV-positive samples were tested by the Vironostika-less sensitive (LS) enzyme(More)
The rapid identification of bacteria and fungi directly from the blood of patients with suspected bloodstream infections aids in diagnosis and guides treatment decisions. The development of an automated, rapid, and sensitive molecular technology capable of detecting the diverse agents of such infections at low titers has been challenging, due in part to the(More)
OBJECTIVES A significant proportion of geriatric patients experience suboptimal outcomes following episodes of emergency department (ED) care. Risk stratification screening instruments exist to distinguish vulnerable subsets, but their prognostic accuracy varies. This systematic review quantifies the prognostic accuracy of individual risk factors and(More)
We describe a novel adaptation of the TaqMan PCR assay which potentially allows for highly sensitive detection of any eubacterial species with simultaneous species identification. Our system relies on a unique multiprobe design in which a single set of highly conserved sequences encoded by the 16S rRNA gene serves as the primer pair and is used in(More)
