Contrary to what you might think, advanced age does not increase the risk of surgical-site infections, according to a large long-term study reported in the April 1 issue of The Journal of Infectious Diseases, now available online. The study, which involved prospectively collected data on thousands of patients in multiple hospitals undergoing various surgical procedures, found that the infection risk increased by about 1 percent per year between the ages of 17 to 65 years but then decreased by about 1 percent per year after age 65; indeed, there were no surgical site infections in patients who were older than age 95.
The explanation for these surprising findings is unknown, but the possibilities may include a tendency by physicians to avoid surgery in frail elderly patients and, conversely, a "hardy survivor" effect, in which a protective genetic makeup may enable elderly patients to withstand the rigors of surgery and its complications.
Keith S. Kaye, MD, MPH, and colleagues at Duke University Medical Center and Durham Veterans Affairs Medical Center studied 144,485 patients over age 16 years with no pre-existing surgical-site infections who were admitted for surgery to 11 hospitals in the southeastern United States between Feb. 1, 1991 and July 31, 2002; the most common surgical procedures were orthopedic (42 percent), gastrointestinal (13 percent), obstetric/gynecologic (11 percent), or cardiothoracic (10 percent). Of the 144,485 patients studied, surgical-site infections developed in 1,684 (1.2 percent), with gastrointestinal procedures (3.1 percent), cardiothoracic procedures (2.3 percent), and vascular procedures (1.7 percent) having the highest rates

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
