$33.9 Billion Spent Out-Of-Pocket On Complementary And Alternative Medicine By Americans
Americans spent $33.9 billion out-of-pocket on complementary and alternative medicine (CAM) over the previous 12 months, according to a 2007 government survey1. CAM is a group of diverse medical and health care systems, practices, and products such as herbal supplements, meditation, chiropractic, and acupuncture that are not generally considered to be part of conventional medicine. CAM accounts for approximately 1.5 percent of total health care expenditures ($2.2 trillion2) and 11.2 percent of total out-of-pocket expenditures (conventional out-of-pocket: $286.6 billion2 and CAM out-of-pocket: $33.9 billion1) on health care in the United States.

New Image Survey Reveals 'Perception Is Reality' When It Comes To Teenagers With Acne
In today"s image-obsessed society where millions of photos are uploaded daily through digital networks such as Facebook and Flickr, how much of an impact can a common skin condition like acne have on the life of teens? Based on first impressions, teens with acne are perceived to have different personality and social traits than if they had clear skin, according to results of a new online perception survey sponsored by the American Acne & Rosacea Society (AARS), and co-authored by Dr. Eva Ritvo, psychiatrist and co-author of The Beauty Prescription.(1) The survey asked thousands of teens and adults to offer their impressions of a group of teens based solely on photos of their faces - with clear skin or digitally enhanced to simulate acne. The results, which are being released to mark the first-ever National Acne Awareness Month, also expose the significant lengths that teens with acne would go to if it meant they could get rid of their acne forever.(1a)

Lobbying Draws On Ranks Of Former Government Officials, Health Industry Coffers
"The nation"s largest insurers, hospitals and medical groups have hired more than 350 former government staff members and retired members of Congress in hopes of influencing their old bosses and colleagues, according to an analysis of lobbying disclosures and other records," the Washington Post reports. The Post"s analysis of lobbying disclosure records shows that three-quarters of major health firms have hired an insider to lobby on their behalf; half of those insiders once worked for the key senators and congressional committees that are now shaping the reform proposals.

Artificial Liver For Drug Tests

If you have hay fever, headaches or a cold, it"s only a short way to the nearest chemist. The drugs, on the other hand, can take eight to ten years to develop. Until now animal experiments have been an essential step, yet they continue to raise ethical issues. "Our artificial organ systems are aimed at offering an alternative to animal experiments," says Professor Heike Mertsching of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart. "Particularly as humans and animals have different metabolisms. 30 per cent of all side effects come to light in clinical trials." The test system, which Professor Mertsching has developed jointly with Dr. Johanna Schanz, should in future give pharmaceutical companies greater security and shorten the path to new drugs. Both researchers received the "Human-centered Technology" prize for their work. "The special feature, in our liver model for example, is a functioning system of blood vessels," says Dr. Schanz. "This creates a natural environment for cells." Traditional models do not have this, and the cells become inactive. "We don"t build artificial blood vessels for this, but use existing ones - from a piece of pig"s intestine." All of the pig cells are removed, but the blood vessels are preserved. Human cells are then seeded onto this structure - hepatocytes, which, as in the body, are responsible for transforming and breaking down drugs, and endothelial cells, which act as a barrier between blood and tissue cells. In order to simulate blood and circulation, the researchers put the model into a computer-controlled bioreactor with flexible tube pump, developed by the IGB. This enables the nutrient solution to be fed in and carried away in the same way as in veins and arteries in humans. "The cells were active for up to three weeks," says Dr. Schanz. "This time was sufficient to analyze and evaluate the functions. A longer period of activity is possible, however." The researchers established that the cells work in a similar way to those in the body. They detoxify, break down drugs and build up proteins. These are important pre-conditions for drug tests or transplants, as the effect of a substance can change when transformed or broken down - many drugs are only metabolized into their therapeutic active form in the liver, while others can develop poisonous substances. The researchers have demonstrated the basic possibilities for use of the tissue models - liver, skin, intestine and windpipe. At the moment, the test system is being examined. Within two years it could provide a safer alternative to animal experiments. Heike Mertsching Fraunhofer-Gesellschaft
