Do the Benefits of Premium Knee Implants Outweigh Extra Costs?

Premium knee implants, such as high-flexion knees were medical devices created to address specific patient needs and to promote additional function.

2011-09-19

WEST PALM BEACH, FL, September 19, 2011 (Press-News.org) Premium knee implants, such as high-flexion knees were created to address specific patient needs and to promote additional function. But whether these higher cost devices provide greater longevity than their standard lower-cost counterparts remains to be seen in the medical literature.

Studies that have evaluated the functional results of premium vs. standard implants have demonstrated similar results between the prostheses.

Since the Zimmer NexGen knee replacement system has been on the market, almost half a million people in the US alone have had Zimmer knee implants. However, the NexGen CR-Flex Porous Femoral component has recently been linked to a variety of problems, from loosening of the implant to failure of the replacement knee, requiring revision surgery.

New imaging technique visualizes cancer during surgery

2011-09-19

Ovarian cancer is one of the most frequent forms of cancer that affect women. As tumors can initially grow unchecked in the abdomen without causing any major symptoms, patients are usually diagnosed at an advanced stage and have to undergo surgery plus chemotherapy. During the operation, surgeons attempt to remove all tumor deposits as this leads to improved patient prognosis. To do this, however, they primarily have to rely on visual inspection and palpation - an enormous challenge especially in the case of small tumor nests or remaining tumor borders after the primary ...

Policies that promote healthy eating could cut heart disease deaths by half

2011-09-19

Research by the University of Liverpool has found that intervention policies that promote healthy eating could cut the death rate for cardiovascular disease (CVD) by up to 50%. Professor Simon Capewell from the Institute of Psychology, Health and Well-being found that intervention policies which reduce unhealthy eating habits can have a significant effect on levels of CVD at both an individual and population level. Poor diet is one of the major causes of CVD and small improvements can make a positive and rapid impact on both the individual and the wider population. ...

Lawrence Livermore Lab Case Set For Trial February 6, 2012 -- 130 Plaintiffs Allege Age Discrimination, Illegal Layoffs

2011-09-19

The lawsuit against Lawrence Livermore National Lab, as referenced in a 9/11/11 New York Times article, is a reflection of very serious issues confronting the laboratory. 130 former plaintiffs allege they were illegally laid off by LLNS in a flagrant demonstration of age discrimination. Tuesday, September 13, 2011 the lawsuit, which was filed May 2009, was set for trial on February 6, 2012 in the Alameda County Superior Court. The law firm of Gwilliam, Ivary, Chiosso, Cavalli & Brewer, Oakland, California represents the 130 plaintiffs in this consolidated action. The ...

Health-based approach may help ID groups at risk of genocide

2011-09-19

Researchers from North Carolina State University are proposing a health-based approach to identifying groups at high risk of genocide, in a first-of-its-kind attempt to target international efforts to stop these mass killings before they start. Genocide, or the willful attempt to exterminate a specific population, is a violation of international law. In recent years, international discussion of genocide has focused in part on finding ways to identify populations at risk in order to prevent a problem before it starts. Some risk factors have already been identified, such ...

How Do Injured Workers Come to Terms with Fears of Losing Their Job if They File a Workers' Compensation Claim

2011-09-19

Today's economic climate is having a dramatic effect on the health and well-being of injured workers. Skyrocketing unemployment rates and a 15% poverty level is a very scary realization. The impact it is having on injured workers is twofold. First, an employee that gets injured is typically living on a budget. If he/she gets injured, that employee will have to readjust that budget to compensate for the reduction in income. Workers' Compensation benefits in Pennsylvania pay between Ninety Percent (90%) and Sixty-Six and Two-Thirds (66 2/3%) of the gross wage. This benefit ...

Common genetic variations linked to both schizophrenia and bipolar risk

2011-09-19

Common genetic variants contribute to the risk of schizophrenia and bipolar disorder, an international research consortium has discovered. Schizophrenia and bipolar disorder are common and often devastating brain disorders, affecting around one per cent of the world's population. A team including Cardiff University scientists has found new molecular evidence that 11 genetic regions have strong links with these diseases, including six regions not previously observed. The researchers also found that many of these DNA variations contribute to both diseases. The findings, ...

Large international study discovers common genetic contributions to mental illness

2011-09-19

CHAPEL HILL, N.C. – A team of over 250 researchers from more than 20 countries have discovered that common genetic variations contribute to a person's risk of schizophrenia and bipolar disorder. The study of more than 50,000 adults ages 18 and older provides new molecular evidence that 11 DNA regions in the human genome have strong association with these diseases, including six regions not previously observed. The researchers also found that many of these DNA variants contribute to both diseases. The findings, reported by the Psychiatric Genome-Wide Association Study ...

Scientists develop new potato lines to wage war on wireworms

2011-09-19

When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, U.S. Department of Agriculture (USDA) scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum. Previous studies showed that the wild potatoes resisted Colorado potato beetles and green peach aphids, two very different pests. Given this broadspread resistance, ...
