Acutely infected individuals are thought to contribute substantially to forward transmissions of HIV; however, diagnosing AHI in resource-limited settings has proven to be a challenge. While fourth generation antigen-antibody combination assays h...

MATERIALS AND METHODS Four hundred and sixty eight sets of film mammograms were evaluated with respect to the Korean and...
PURPOSE To establish the utility of apparent diffusion coefficient (ADC) entropy in discrimination of benign and malignant adnexal lesions, using histopathology as the reference standard, via comparison of the diagnostic performance of ADC entropy with mean ADC and with visual assessments of adnexal lesions on conventional and diffusion-weighted sequences. MATERIALS AND METHODS In all, 37 adu...

BACKGROUND Studies with methodologic shortcomings can overestimate the accuracy of a medical test. We sought to determine and compare the direction and magnitude of the effects of a number of potential sources of bias and variation in studies on estimates of diagnostic accuracy. METHODS We identified meta-analyses of the diagnostic accuracy of tests through an electronic search of the databas...
BACKGROUND Health technology assessments of surgical interventions frequently require the inclusion of non-randomised evidence. Literature search strategies employed to identify this evidence often exclude a methodological component because of uncertainty surrounding the use of appropriate search terms. This can result in the retrieval of a large number of irrelevant records. Methodological fil...
The feasibility and acceptability of a two-step screening protocol for delirium identification was pilot tested. Step 1, a screening tool, comprises two items: "Please tell me the day of the week," and "Please tell me the months of the year backwards starting with December." If either/both items are incorrect, Step 2, a 3-minute diagnostic assessment, follows. Trained researchers enrolled 24 ho...
