Study findings published online in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also indicate that RA patients have a higher infection risk following total knee replacement than patients with OA.
The ACR reports that OA—the most common form of arthritis—affects 27 million Americans 25 years of age and older, and another 1.3 million adults are living with RA. Previous studies show that one of the most effective treatment options for end-stage arthritis of the hip or knee is total joint replacement. Experts suggest that success with this intervention is evident given the increasing rates of joint replacements. According to the Centers for Disease Control and Prevention (CDC) 676,000 total knee replacements and 327,000 total hip replacements were performed in the U.S. in 2009.
"Joint arthroplasty is successful in relieving the pain and disability caused by hip or knee arthritis," said lead author Dr. Bheeshma Ravi from the University of Toronto and Women's College Research Institute (WCRI) in Canada. "While complication rates are low there are some cases with serious consequences that include infection, joint dislocation, blood clots and even death."
To explore this important issue, Dr. Ravi and colleagues conducted a systemic review of the literature to assess complication risk in OA and RA patients following joint replacement surgery. Evidence from January 1990 to December 2011 was evaluated and 40 studies were included in the analysis. The study population included patients aged 18 years or older who had hip or knee replacements and excluded patients who had replacement surgery due to a fracture or cancer. Studies that involved 200 joints or more were incorporated in the current analysis.
Analysis shows RA patients had a higher risk of dislocation following hip replacement surgery than patients with OA. RA patients who had total knee replacements were also at higher risk of infection compared to those with OA. The team found no difference in revision rate, 90-day mortality or blood clot risk between the two patient groups. Dr. Ravi concludes, "Additional studies to confirm our findings are necessary and further investigation of possible reasons for differences in joint replacement complication rates between RA and OA patients is needed."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
