BACKGROUND Elizabethkingia meningoseptica is a nosocomial-adapted Gram-negative bacillus intrinsically resistant to antibiotics commonly used in the intensive care setting. An outbreak investigation commenced when five patients developed E. meningoseptica infection in two intensive care units (ICUs). METHODS Analysis of laboratory data, case reviews, ICU(More)
An epidemiological survey to characterize Entamoeba histolytica/E dispar isolates from 123 human subjects was carried out in the Wonji area of Central Ethiopia, where an increased incidence of amoebic infection has been reported. In a randomized, coproparasitological study, 93 (75.6%) of the subjects were found positive for at least one species of(More)
MOTIVATION Computational inference methods that make use of graphical models to extract regulatory networks from gene expression data can have difficulty reconstructing dense regions of a network, a consequence of both computational complexity and unreliable parameter estimation when sample size is small. As a result, identification of hub genes is of(More)
Constraint-based learning of Bayesian networks (BN) from limited data can lead to multiple testing problems when recovering dense areas of the skeleton and to conflicting results in the orientation of edges. In this paper, we present a new constraint-based algorithm, light mutual min (LMM) for improved accuracy of BN learning from small sample data. LMM(More)
Results Upon review laboratory data revealed an unrecognized subtle increasing trend of E. meningoseptica clinical infections in all ICUs over the preceding 3 years. E. meningoseptica was cultured from aerators of 44% (35/79) taps. Taps in sinks frequently used for non-sanctioned practices were more likely to be contaminated (95% CI 1.2-2.3, p<0.003).(More)
In this section, we consider some of the characteristics of partial correlations between directly dependent variables when conditioning on a large set of true neighbors of either variable. This material is complementary to the discussion of Section 5 (main paper). The considered characteristics are summarized in Conjecture 1. Here, we only provide a proof(More)
