Medical Research Feared To Be Negatively Affected By Economic Downturn

According to professor David Wield, director of the Economic and Social Research Council’s Innogen Centre, venture capital investment is likely to fall short of the £32-billion total it received in 2007.
“[Venture capital] is often the main source of funding in the early stages of development and, without this, biotech firms will struggle to get their projects off the ground,” he says.
“This year started well but in recent months it has started drying up. It is a real worry.”
He added: “Like many other sectors, the pharmaceutical industry has had tough times recently - there is seemingly no way to speed up and improve the drug discovery pipeline, and heavily increased R&D has not increased the number of new drugs.
“As a result, big companies have been laying off staff and closing down research units.”
FDA Said To Regularly Approve Experimental Procedures

The New York Times had an article today on how the FDA sometimes approves new treatment techniques without thoroughly vetting them. The article cites Karen Medlock as an example. A breast cancer patient, Medlock was given the option to prevent an excised cancerous lump from returning using radioactive “seeds” that are inserted into the tumor site. The treatment could be completed in five days as opposed to conventional irradiation that takes typically six weeks. The only problem, she learned, was that the procedure is still highly experimental.
Her case is indicative of a wider trend, the New York Times claims. In fact, Medicare often pays doctors more money for using new procedures, which thus become widely adopted.
From the article:
F.D.A. officials defend the quick-review process as a way to promote innovation. Because most new products are simply an improvement on an existing device, they say, there is rarely need for a full review.
Demanding lengthy study of such devices would be “very, very inappropriate and a waste of resources,” said Dr. Daniel G. Schultz, the director of the F.D.A.’s Center for Devices and Radiological Health.
The agency let MammoSite on the market on the basis of a study involving only 25 women that did not answer the fundamental question of how effective it is against breast cancer. Six years later, many cancer specialists say there is still no conclusive proof that it works as well as conventional radiation. The F.D.A. says it did require a label warning that the system had not been shown to be a substitute for conventional radiation.
Dr. Valery Uhl, the radiation oncologist who provided Ms. Medlock’s second opinion, outlined the evidence behind the available treatments. Ms. Medlock chose conventional external-beam radiation because of its well-documented record of success in preventing the return of cancer. To use an unproven therapy like MammoSite, Dr. Uhl said, “makes me really nervous.”
Critics say the F.D.A.’s process for reviewing medical technology, under which medical devices have become a $75 billion-a-year industry in this country, is often too lax. More devices, they say, should get the same scrutiny applied to new drugs. While that process is not perfect, a new drug is typically studied in hundreds or even thousands of patients before the F.D.A. will approve it as safe and effective.
But under the fast-track review for most devices, a product’s effectiveness is never directly established. Regulators simply determine if the device does what its maker says it does — in MammoSite’s case, that it delivers radiation — and whether it poses any undue safety risks.
In response to a Congressional request to study the effectiveness of the F.D.A.’s device-review process, the nonpartisan Government Accountability Office is expected to release a report next month.
Critics say that when the F.D.A. clears a device, the public may wrongly assume that the government has proof it is medically effective. F.D.A. approval has been “widely misinterpreted,” said Dr. Jay R. Harris, the chairman of radiation oncology at the Dana-Farber Cancer Institute and Brigham and Women’s Hospital in Boston.
Medical Tourism On The Rise

Westerners and Arabs are flocking to Asia for affordable medical care. While medical tourism in the past was mainly relegated to cosmetic and dental procedures, a gowing number of patients are travelling abroad for procedures including coronary bypass surgery, transplants, and other complex procedures.
From the site My Sinchew:
With the cost of medical treatment skyrocketing in their home countries, more and more patients are travelling overseas for health care each year, a phenomenon now known as ‘medical tourism’.
And the most favoured destination is Asia where hospitals offer world-class medical services at just a fraction of the cost in the US or Europe with a vacation at an exotic resort as an inviting option.
A recent report, Asian Medical Tourism Analysis (2008-2012), said the region generated revenues worth US$3.4 billion from medical tourism in 2007, accounting for nearly 12.7% of the global market.
The Asian medical tourism market is expected to grow at an annual average of 17.6% between 2007 and 2012, the report said.
The report identified the five biggest Asian medical tourism markets as Thailand, Singapore, India, Malaysia and the Philippines.
