AMA Mum on Menthol Cigarette Exemption
The American Medical Associated voted Tuesday to defer comment on a proviso in federal tobacco legislation that would grant an exemption to menthol while banning other cigarette flavor additives such as mint, clove, and vanilla.
The AMA voted "to refer the decision on menthol to its board, effectively silencing the doctors who wanted the organization to speak out against the exemption," the Associated Press reported. The exemption is key to a compromise that would give regulatory control of cigarettes to the U.S. Food and Drug Administration.
While the other additives tend to be favored by younger people, menthol is preferred by more than 75 percent of blacks who smoke. That compares to fewer than 25 percent of whites who smoke, the AP said, citing government estimates.
Former Secretary of Health and Human Services Louis Sullivan, who held the post from 1989 to 1993, is among seven former health secretaries who have written to Congress opposing the menthol exemption.
"If we're banning things such as clove and peppermint, then we should ban menthol," he said. "This bill [if it includes the exemption] will be discriminatory against African-Americans."
But AMA President Dr. Ron Davis is among those who favors keeping the exemption, having said that removing it could threaten passage of the entire bill, the AP reported. "It would change the entire political dynamic," he said.
New Alzheimer's Drug Shows Promise
The experimental Alzheimer's disease drug bapineuzumab appears to be effective in some patients, according to mid-stage study results released Tuesday by drug makers Wyeth and Elan Corp, the Wall Street Journal reported.
In patients with a gene known to increase the risks of Alzheimer's -- and of developing the disease at an earlier stage -- the drug showed statistically significant clinical improvements. This did not occur in patients without the gene, who were at greater risk for fluid buildup in the brain, especially when taking the drug at higher doses.
Detailed results of the study are expected to be presented July 29 at the International Conference on Alzheimer's Disease in Chicago. The drug has received a fast-track designation from the U.S. Food and Drug Administration. It's expected that it will be at least two years before Wyeth and Elan apply for FDA approval of bapineuzumab, the Wall Street Journal reported.
The drug is designed to attack beta-amyloid. Many experts believe that a build-up of this substance in the brain causes Alzheimer's disease.
U.S. Employers Facing Big Increases in Health Care Costs
Health care costs for American employers are expected to increase 9.9 percent this year and another 9.6 percent in 2009, says a PriceWaterhouseCoopers study released Tuesday.
There are two main reasons for the rising costs, the study said. One is an increase in the expenses people with insurance are paying for people without coverage. Second, many hospitals are replacing facilities and adding private rooms and outpatient treatment centers, the Associated Press reported.
"Health care providers, insurers and employers will have to monitor medical costs carefully if we are to avoid a resurgence of the double-digit annual increases seen in the past," said Dr. David Chin, leader of the Health Research Institute at PriceWaterhouseCoopers.
