Researchers reviewed records of all total hip replacement (THR, or total hip arthroplasty) patients between 2007 and 2009 to identify patients who used tobacco products at the time of surgery, or who smoked regularly prior to surgery.
There were 110 patients who regularly smoked, with a mean age of 55 and a mean follow up of 46 months following THR. A control group was matched 2:1 with the smoking group based on gender, date of surgery within six months, age within five years, related medical conditions (co-morbidities) and immunosuppressive conditions. The smoking group was categorized as current or former smokers, and according to the number of packs of cigarettes smoked per year.
At the most recent follow up, the patients who smoked had a 92 percent survival rate compared to 99 percent for non smokers. Of the nine THR revisions in smokers, four were done to alleviate pain and/or to repair a loose acetabular component (the hip socket), and five resulted from infection. Of the current smokers, six of 65 had revisions (9.2 percent); of the former smokers, 2 out of 45 patients (4.4 percent).
Overall, the patients who smoked had a higher overall revision rate and a higher incidence of other complications. The study authors recommend smoking cessation programs for all patients considering THR.

A Nation in Motion
More than one in four Americans have bone or joint health problems, making them the greatest cause of lost work days in the U.S. When orthopaedic surgeons restore mobility and reduce pain, they help people get back to work and to independent, productive lives. Orthopaedic surgeons provide a great value, in both human and economic terms; and access to high-quality orthopaedic care keeps this "Nation in Motion."

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
