Following a total joint replacement, anticoagulation (blood thinning) drugs can prevent Deep Vein Thrombosis (DVT), a blood clot deep within the extremities, or a pulmonary embolism (PE), a complication that causes a blood clot to move to the lungs. However, prolonged use of these therapies may increase the risk of hemorrhage and infection.
In the study, "Aspirin was Effective to Prevent Proximal DVT and PE in TKA and THA - Analysis of 1,500 Cases," presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), investigators performed a venography, a test for DVT, before and after knee or hip surgery on 1,500 patients. All patients used a foot pump and wore an elastic stocking immediately after surgery. In addition, each patient took a regular dose of aspirin beginning two days post-surgery.
The incidence of DVT was 19.2 percent (32.7 percent in total knee replacement and 5.6 percent in total hip replacement patients) which is below normal. None of the PE cases were fatal or severe, and there were no complications caused by the aspirin. Age and a high patient body mass index (BMI) were among the factors associated with a higher risk for DVT. Aspirin, along with the use of stockings and a foot pump, are safe and effective therapies in preventing DVT and PE in most joint replacement patients. Patients at high risk for DVT made require the use of anticoagulation therapies.
About the AAOS
With more than 37,000 members, the American Academy of Orthopaedic Surgeons, (http://www.aaos.org) or (http://www.orthoinfo.org) is the premier not-for-profit organization that provides education programs for orthopaedic surgeons and allied health professionals, champions the interests of patients and advances the highest quality of musculoskeletal health. Orthopaedic surgeons and the Academy are the authoritative sources of information for patients and the general public on musculoskeletal conditions, treatments and related issues. An advocate for improved care, the Academy is participating in the Bone and Joint Initiative (http://www.usbjd.org), the global initiative to raise awareness of musculoskeletal health, stimulate research and improve people's quality of life. The Academy's 2012 Annual Meeting is being held February 7 - 11, 2012 at the San Francisco Moscone Center in San Francisco.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
