This CoNS was sensible to linezolid, teicoplanine, vancomycin and rifampicin. This information was relevant for antibiotherapy planning. The patient was successfully treated with teicoplanin together with the catheter exchange. In conclusion, infections should be treated with adequate doses and duration of antibiotics together with catheter exchange. Pre-emptive measurements in the cancer patient and establishing the most adequate treatment are imperative for obtaining good results.展开更多

We include a repulsion rule to simulate segregation processes that does not require calculation of the interaction forces between particles, so binary fluids can be described on a mesoscopic scale. The model is conceptually simple and computationally efficient; it maintains Galilean invariance and conserves the mass and energy in the system at the micro- and macro-scale, whereas momentum is conserved globally. For a wide range of temperatures and densities, the model yields results in good agreement with the known properties of binary fluids, such as the density profile, interface width, phase separation, and phase growth. We also apply the model to the study of binary fluids in crowded environments with consistent results.展开更多
