Poorly-performing hand implants unacceptable says leading medical journal

2012-08-09
(Press-News.org) Los Angeles, CA (August 09, 2012) Poorly-performing medical implants have hit the headlines recently, and the trend looks set to continue: the September issue of the Journal of Hand Surgery (JHS) homes in on the unacceptable performance of hand implants for osteoarthritis patients. Citing several recent studies, the editorial asks why these implants – which perform worse that certain hip replacement implants now deemed unacceptable – are still widely used. JHS is an online and print, orthopedic surgery journal published by SAGE.

The issue reports on a number of thumb arthroplasties – joint replacement operations at the base of the thumb – which are often used to treat arthritis. Orthopedic surgeons and the medical profession in general will be interested in research following up on outcomes for a range of implant brands used in this type of surgery. JHS names those that failed to make the grade, and recommends that they should be withdrawn.

Patients who have received a de la Caffiniere implant can expect good long term outcomes following their surgeries. However, those whose joints were replaced with the Moje, Elektra and Pi2 thumb CMC joint implants have less to celebrate, according to the latest follow-up research.

Editor-in-Chief, Grey Giddins, calls for people to readdress their opinions on using what is known and what is not necessarily the best, over what may be less known, but is ultimately performing better:

"We should make a stand as a profession and stop using implants with known poor outcomes unless other data is published to change our minds. Moreover, we should continue to be careful about being encouraged into using other new implants until adequate long term follow-up is available."

Supported by notable research studies, the editorial suggests that failing Moje and Electra implants should be withdrawn, and while just one study on the Pi2 implant is insufficient to recommend withdrawal, the journal asks surgeons to use it with caution in future.

Eating grapes may help protect heart health in men with metabolic syndrome, new study suggests

2012-08-09
Fresno, Calif. – Consuming grapes may help protect heart health in people with metabolic syndrome, according to new research published in the Journal of Nutrition. Researchers observed a reduction in key risk factors for heart disease in men with metabolic syndrome: reduced blood pressure, improved blood flow and reduced inflammation. Natural components found in grapes, known as polyphenols, are thought to be responsible for these beneficial effects. The randomized, placebo-controlled, crossover study, led by principal investigator Dr. Maria Luz Fernandez and Jacqueline ...

Potential drug molecule shows enhanced anti-HIV activity

Potential drug molecule shows enhanced anti-HIV activity
2012-08-09
Researchers from Munich and Naples have shown that minimal modification of a synthetic peptide with anti-HIV activity results in a new compound with more than two orders of magnitude higher binding affinity to the chemokine receptor CXCR4 and greatly improved anti-HIV activity. This could be a step toward the design of new, more effective drugs against AIDS, inflammatory diseases, and some forms of cancer. Different strains of HIV-1 use either the chemokine receptor CCR5 or CXCR4 for entry into immune cells. While drugs that block usage of CCR5 by the virus are already ...

Carnegie Mellon study shows skin-aging radicals age naturally formed particles in the air

2012-08-09
PITTSBURGH—Pine trees are one of the biggest contributors to air pollution. They give off gases that react with airborne chemicals – many of which are produced by human activity – creating tiny, invisible particles that muddy the air. New research from a team led by Carnegie Mellon University's Neil Donahue shows that the biogenic particles formed from pine tree emissions are much more chemically interesting and dynamic than previously thought. The study provides the first experimental evidence that such compounds are chemically transformed by free radicals, the same compounds ...

Neolithic man: The first lumberjack?

Neolithic man: The first lumberjack?
2012-08-09
During the Neolithic Age (approximately 10000 BCE), early man evolved from hunter-gatherer to farmer and agriculturalist, living in larger, permanent settlements with a variety of domesticated animals and plant life. This transition brought about significant changes in terms of the economy, architecture, man's relationship to the environment, and more. Now Dr. Ran Barkai of Tel Aviv University's Department of Archaeology and Ancient Near Eastern Civilizations has shed new light on this milestone in human evolution, demonstrating a direct connection between the development ...

Rhode Island Hospital study: Bariatric patients with obstructive sleep apnea fail to show symptoms

2012-08-09
PROVIDENCE, R.I. – A Rhode Island Hospital researcher has found that the majority of bariatric surgery patients being treated for obesity have clinically significant obstructive sleep apnea (OSA), but report fewer symptoms than other sleep disorders patients. The study by Katherine M. Sharkey, M.D., Ph.D., of the department of medicine, division of pulmonary, critical care and sleep medicine at Rhode Island Hospital, and University Medicine, is published online in advance of print in the journal Sleep and Breathing. "Patients with obstructive sleep apnea frequently complain ...

First antibiotic stewardship probed in the Journal of the Pediatric Infectious Diseases Society

2012-08-09
ARLINGTON, VA, August 9, 2012—The Journal of the Pediatric Infectious Diseases Society (JPIDS) today released the largest and most rigorous evaluation to date of the impact on reducing the days of antibiotic therapy in a children's hospital using a prospective-audit-with-feedback antibiotic stewardship program (ASP). The study utilized a control group of the 25-member children's hospitals of the Child Health Corporation of America. A companion article describes how the ASP was created within this 317-bed tertiary care children's hospital and clinicians' attitudes toward ...

Solar power day and night
2012-08-09
This press release is available in German.Energy storage systems are one of the key technologies for the energy turnaround. With their help, the fluctuating supply of electricity based on photovoltaics and wind power can be stored until the time of consumption. At Karlsruhe Institute of Technology (KIT), several pilot plants of solar cells, small wind power plants, lithium-ion batteries, and power electronics are under construction to demonstrate how load peaks in the grid can be balanced and what regenerative power supply by an isolated network may look like in the future. "High-performance ...

Treating drug resistant cancer through targeted inhibition of sphingosine kinase

2012-08-09
Scientists at Tulane University School of Medicine, led by Dr. James Antoon and Dr. Barbara Beckman, have characterized two drugs targeting sphingosine kinase (SK), an enzyme involved in cancer growth and metastasis. New treatments specifically attacking cancer cells, but not normal ones, are critical in the fight against cancer. The results, which appear in the July 2012 issue of Experimental Biology and Medicine, demonstrate the role of SK in drug resistance and therapeutic potential of SK inhibitors. "Sphingosine kinase is a relatively new molecular target," says ...

Are there gender differences in anti-HIV drug efficacy?

Are there gender differences in anti-HIV drug efficacy?
2012-08-09
New Rochelle, NY, August 9, 2012—Women comprise nearly half of the HIV-infected population worldwide, but these 15.5 million women tend to be under-represented in clinical trials of anti-HIV drug therapies. The U.S. Food and Drug Administration (FDA) has created a database from 40 clinical studies to assess gender differences in the efficacy of antiretroviral treatments. The results of this study are presented in an article in AIDS Patient Care and STDs, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the AIDS Patient Care ...

Potential Nipah vaccine passes primate test

2012-08-09
Researchers have successfully tested a vaccine for the deadly Nipah virus in monkeys, raising hopes that it could provide similar protection for humans. With greater than a 75 percent fatality rate and the ability to be transmitted directly from person to person, Nipah has long been a significant concern for infectious-disease experts. The virus, which is carried naturally by fruit bats, was first discovered in Malaysia in 1998. Outbreaks have occurred in nearly every year since, in Singapore, Bangladesh and India. "This vaccine is based on a protein from Hendra virus, ...
