AIMS Echocardiographic contrast (EC) improves the diagnostic accuracy of suboptimal echocardiograms. In October 2007, the Food and Drug Administration (FDA) placed a black box warning on the label of the perflutren-based agents Definity and Optison, contraindicating their use in patients with pulmonary hypertension (PHT) and unstable cardiopulmonary status, after serious cardiopulmonary reactio...
BACKGROUND This study examined colonisation with and characteristics of antimicrobial-resistant organisms among residents of a long-term care facility (LTCF) over one year, including strain persistence and molecular diversity among isolates of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. METHODS Sixty-four residents of a LTCF were recruited (51 at baseline, 13 during ...
OBJECTIVE To determine factors influencing overall survival following recurrence (OSFR) in women with low-risk endometrial cancer (EC) treated with surgery alone. METHODS A multicenter, retrospective department database review was performed to identify patients with recurrent "low-risk EC" (patients having less than 50% myometrial invasion [MMI] with grade 1 or 2 endometrioid EC) at 10 gyneco...
We proposed in a previous paper [Opt. Commun. 228, 33 (2003)] a modified radiative transfer equation to describe radiative transfer in a medium with a spatially varying refractive index. The present paper is devoted to the demonstration that this equation perfectly works in the non-absorbing / non-scattering limit, what was contested by L. Martí-López and coworkers [Opt. Commun. 266, 44 (2006)]...
We investigate the impossibility of solving certain problems in an unreliable distributed system where multiple processes may fail. A necessary condition is provided for the solvability of problems in the presence of multiple faulty processes, and variants of problems which are unsolvable in the presence of a single faulty pro~~s (such as consensu.s, ehoo~ing a leader, r~g, matching) are shown ...
Electronic structure theory under the influence of apolar solvents suffers from substantial methodical difficulties since in this case the solvent-induced solute polarization originates mainly from specific directional interactions and higher electric multipoles. Continuum solvation models based on the dielectric solvent response such as the PCM approach ignore such interactions and can therefo...
