TL;DR: In this paper, a single sample was obtained per patient and was evaluated using an assay to detect serum β-D-glucan derived from fungal cell walls (range, 0 to > 7000 pg/mL).
Abstract: BACKGROUND Measurement of (1-->3)-beta-D-Glucan (BG) has emerged as an adjunct diagnostic strategy for invasive fungal infections (IFI). METHODS Subjects at 6 clinical sites in the United States were enrolled as either fungal infection-negative subjects (n = 170) or subjects with proven or probable IFI according to European Organization for the Research and Treatment of Cancer/Mycoses Study Group criteria (n = 163). A central laboratory and 4 sites performed assays. A single sample was obtained per patient and was evaluated using an assay to detect serum BG derived from fungal cell walls (range, 0 to > 7000 pg/mL). RESULTS At a cutoff of 60 pg/mL, the sensitivity and specificity of the assay were 69.9% and 87.1%, respectively, with a positive predictive value (PPV) of 83.8% and a negative predictive value (NPV) of 75.1%. At a cutoff value of 80 pg/mL, the sensitivity and specificity were 64.4% and 92.4%, respectively, with a PPV of 89% and an NPV of 73%. Of the 107 patients with proven candidiasis, 81.3% had positive results at a cutoff value of 60 pg/mL, and 77.6% had positive results at a cutoff value of 80 pg/mL. Of the 10 patients with aspergillosis, 80% had positive results at cutoff values of 60 and 80 pg/mL. The 3 subjects diagnosed with Fusarium species had positive results at a cutoff value of 60 pg/mL. Patients infected with Mucor or Rhizopus species (both of which lack BG) had negative results at both cutoff values, and of the 12 patients with Cryptococcus infection, 3 had positive results at a cutoff value of 60 pg/mL, and 2 had positive results at a cutoff value of 80 pg/mL. Of the subjects with proven positive results who were receiving antifungal therapy (n = 118), 72.9% had results positive for BG at a cutoff value of 60 pg/mL, and 69.5% had results positive for BG at a cutoff value of 80 pg/mL. The interlaboratory sample test r2 was 0.93. CONCLUSION Reproducible assay results with high specificity and high PPV in a multicenter setting demonstrate that use of an assay to detect serum BG derived from fungal cell walls is a useful diagnostic adjunct for IFI.

TL;DR: In this article, the authors analyzed left ventriculograms for diastolic and systolic volumes, global left ventricular sphericity, extent of wall motion abnormality, and endocardial curvature and found that the presence of MR was related to the risk of developing a cardiovascular event during 3.5 years of follow-up.
Abstract: Background Mitral regurgitation (MR) may complicate acute myocardial infarction (MI). However, it is not known whether mild MR is an independent predictor of post-MI outcome. Methods and Results The study cohort consisted of 727 Survival and Ventricular Enlargement Study patients who underwent cardiac catheterization, including left ventriculography, up to 16 days after MI. Left ventriculograms were analyzed for diastolic and systolic volumes, global left ventricular sphericity, extent of wall motion abnormality, and endocardial curvature. The presence of MR was related to the risk of developing a cardiovascular event during 3.5 years of follow-up. MR was present in 141 patients (19.4%). Severe (3+) MR was present in only 2 patients. Patients with MR were more likely to have a persistently occluded infarct artery (MR versus no MR, 27.3% versus 15.2%; P=.001). Although the ejection fractions were similar, MR patients had larger end-systolic and end-diastolic volumes and more spherical ventricles than patie...

TL;DR: The cerebral organization of word identification processes in reading was examined using functional magnetic resonance imaging (fMRI) and a strategy of multiple subtractions was employed in order to validate relationships between structure and function.
Abstract: The cerebral organization of word identification processes in reading was examined using functional magnetic resonance imaging (fMRI). Changes in fMRI signal intensities were measured in 38 subjects (19 males and 19 females) during visual (line judgement), orthographic (letter case judgement), phonological (nonword rhyme judgement) and semantic (semantic category judgement) tasks. A strategy of multiple subtractions was employed in order to validate relationships between structure and function. Orthographic processing made maximum demands on extrastriate sites, phonological processing on a number of frontal and temporal sites, and lexical-semantic processing was most strongly associated with middle and superior temporal sites. Significant sex differences in the cerebral organization of reading-related processes were also observed.

TL;DR: Induction of labor at 39 weeks in low‐risk nulliparous women did not result in a significantly lower frequency of a composite adverse perinatal outcome, but it did result in less frequency of cesarean delivery.
Abstract: Background The perinatal and maternal consequences of induction of labor at 39 weeks among low-risk nulliparous women are uncertain. Methods In this multicenter trial, we randomly assigned...
