Randomized Controlled Trial Multicenter StudyComparison of Levofloxacin versus Moxifloxacin for Multidrug-Resistant Tuberculosis.
Levofloxacin (LFX) and moxifloxacin (MXF) are the two most frequently recommended fluoroquinolones for treatment of patients with multidrug-resistant tuberculosis (MDR-TB). However, studies comparing the effectiveness of LFX and MXF among patients with MDR-TB are lacking. ⋯ The choice of LFX or MXF for treatment of patients with MDR-TB may not affect sputum culture conversion at 3 months of treatment. Clinical trial registered with www.clinicaltrials.gov (NCT 01055145).

Mortality among Patients Admitted to Strained Intensive Care Units.
The aging population may strain intensive care unit (ICU) capacity and adversely affect patient outcomes. Existing fluctuations in demand for ICU care offer an opportunity to explore such relationships. ⋯ Several sources of ICU strain are associated with small but potentially important increases in patient mortality, particularly in ICUs employing closed staffing models. Although closed ICUs may promote favorable outcomes under static conditions, they are susceptible to being overwhelmed by patient influxes.
