Use of TYRX, Inc.'s AIGISRx® Antibacterial Envelope reduced major infection rates by more than 90% in patients undergoing Cardiovascular Implantable Electronic Device (CIED) replacement procedures compared to similar high-risk cohorts, according to the CITADEL & CENTURION clinical study results presented on Saturday at the Late Breaking Clinical Trials session at Heart Rhythm 2013, the Heart Rhythm Society's 34th Annual Scientific Sessions.
AIGISRx® Antibacterial Envelope is indicated for holding a pacemaker or implantable cardioverter-defibrillator, thereby creating a stable environment surrounding the device and leads after surgical placement. The biocompatible mesh is coated with antibiotics that elute (dissolve) within a 7 to 10 day period.

CITADEL / CENTURION is a prospective, multicenter clinical study to evaluate the major device infection and mechanical complication rates in the 12 months after implantation, in patients at high risk for CIED infection who have their CIED implanted with an AIGISRx Antibacterial Envelope. Study patients were enrolled at 55 US centers, and were at high-risk for infection because they were undergoing a CIED replacement procedure with an implantable cardioverter-defibrillator (ICD), (CITADEL), or a cardiac resynchronization therapy (CRT) device (CENTURION). The results from a planned interim analysis of the primary endpoints for the first 1000 eligible patients after 90 days of follow up were presented by Dr. Charles A. Henrikson, the Chief of Electrophysiology at the Oregon Health Sciences University.
Key study findings include:
There was 1 major infection (0.1%), the primary efficacy endpoint of the study, after 90 days of follow-up. There were 11 minor infections (limited to the incision and skin) (1.1%).
The incidence of the most common mechanical complication, major hematomas (1.5%), was not significantly different than the pre-defined control cohort (2.3%; P = NS).
This study was funded by TYRX, Inc.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
