METHODS: From June 2006 to September 2009, 1,646 patients were entered into the INTERMACS database in which adverse S63845 mouse events and outcomes were recorded for primary implants with LVAD or BiVAD. Competing outcomes methodology was used to estimate the time-related probability of death, transplant, or recovery. Overall survival for all groups was analyzed with Kaplan-Meier methods and Cox proportional regression analysis.

RESULTS: The distribution of primary device implants included 1,440 LVADs and 206 BiVADs. BiVAD patients presented

with a lower INTERMACS profile 93% in INTERMACS 1 or 2, compared with 73% for LVAD patients (p < 0.001). Survival at 6 months was 86% for LVADs and 56% for BiVADs (p < .0001). Adverse event rates, expressed as episodes/100 patient-months for the BiVAD group compared with LVAD, were significantly higher for infection (33.2 vs

14.3), bleeding (71.6 vs 15.5), neurologic events (7.9 vs 2.6), and for device failure (4.9 vs 2.0).

CONCLUSIONS: Patients requiring BiVAD support at the time of durable MCS implant are more critically ill at the time of MCS implant. BiVAD patients experience worse survival than patients supported with LVAD alone and higher rates of serious adverse events. Characteristics of the population present at the time of BiVAD implant likely influence PCI 32765 post-implant MCS outcomes.

“We study the resonant tunneling magneto-resistance (TMR) of a multiferroic resonant tunneling diode, which is hybridized of ferroelectric double barriers and a ferromagnetic quantum well. Using the nonequilibrium Green’s function method we show that magneto-currents through the resonant tunneling diode and its current spin

polarization can be manipulated by changing the relative direction of an applied magnetic field to the spontaneous magnetic field in the diluted magnetic semiconductor quantum well as well as by reversing dipole polarization directions in ferroelectric barriers. With these results, we propose a multiferroic spin device to control the amount of current and spin polarization of current through it. (c) 2011 American Institute of Physics.

“PURPOSE: To determine the incidence of intraoperative floppy-iris syndrome (IFIS) in patients taking tamsulosin who had surgery by resident physicians, the effect of prophylactic intracameral lidocaine epinephrine on the incidence, and the relationship between preoperative dilated pupil diameter and the incidence.

SETTING: Tertiary care hospital, Seattle, Washington, USA.
