FDA Expands Peanut Butter Recall
The recall of salmonella-causing peanut butter processed at a plant in Georgia hasn't yet ended.
The U.S. Food and Drug Administration has expanded the recall to include all Peter Pan and Great Value brand peanut butter manufactured at the ConAgra plant in Sylvester back to October 2004. Both carry the product code 2111, the FDA says.
The FDA gave no reason for the expanded recall in its March 9 consumer alert other than to say it was made after information was obtained from its ongoing investigation into the salmonella infections, which have been confirmed in more than 400 persons in 42 states since it was first detected in mid-February.
The FDA alert says, "Consumers who have purchased any of the products since October 2004 should discard them. FDA's advice to consumers continues to be not to eat any Peter Pan peanut butter or any Great Value peanut butter beginning with the 2111 product code."
"The most likely scenario is that the peanut butter became contaminated sometime during the production, between the roasting process and putting the product in a jar," said Dr. David Acheson, the FDA's Director of the Food Safety and Security Staff in the Center for Food Safety and Applied Nutrition, said March 1.
Symptoms of food-borne illness caused by salmonella include fever, diarrhea and abdominal cramps. It is rarely fatal, but can cause more serious health problems among the very old and very young.

1-in-10 Brits is a 'Secret Smoker', Survey Finds
Knowing that quitting smoking is the right thing to do is one thing. Actually quitting is another matter entirely.
A recent survey of 4,000 adults in England reveals that one-in-10 is a "secret smoker," so secret, in fact, that many don't even reveal it to their own doctor.
According to BBC News, the survey was commissioned by Boots, a large British pharmacy chain, and it found that 52 percent of the secret smokers hid their habit from their parents, even into adulthood. What's even more surprising is that fully a third kept their smoking habits from their doctor.
And another third said they lied to their family members, some of whom believed they had never smoked or had given it up.
For some reason, the BBC reports, Londoners are more likely to keep their habit secret, followed by those who live in Yorkshire. No reason was given for this.

U.S Prescription Drug Sales Increased 8.3 Percent in 2006
The new Medicare drug benefit was one of the factors that helped push U.S. prescription drug sales up by 8.3 percent in 2006 to $249.9 billion, according to a report by IMS Health, which provides data to the drug and health-care industries.
Prescriptions dispensed through the Medicare drug benefit accounted for 17 percent of retail prescriptions last year, the report noted.
Increased use of generic drugs and new treatments for diseases such as diabetes and cancer were among the other factors behind the increase, the Associated Press reported.
In 2006, sales of generic drugs increased 22 percent to $27.4 billion.
The report said it's expected that the rate of growth of prescription drug sales will slow in 2007, but will likely maintain a compounded annual rate of between 6 percent and 9 percent through 2010, the AP reported.

Kroger Ensures Access to Morning-After Pill
In response to a Georgia woman's complaint that she was denied access to the morning-after contraceptive pill by a pharmacist at a Kroger store, the grocery chain said Friday that it's reiterating its drug policy to all of its pharmacists.
The company policy states that if a pharmacist objects to handling a customer's prescription, the store must take steps to ensure the prescription is filled, the Associated Press reported.
"We believe that medication is a private patient matter," said Kroger Co. spokeswoman Meghan Glynn. "Our role as a pharmacy operator is to furnish medication in accordance with the doctor's prescription or as requested by a patient."
The company restated its policy after a Rome, Ga., woman said a Kroger pharmacist refused to give her the Plan B emergency contraceptive, also known as the morning-after pill, the AP reported.
If taken within 72 hours of unprotected sex, the drug can reduce the risk of pregnancy by up to 89 percent.
Other major pharmacy chains, including Walgreen Co., Rite-Aid Corp., and CVS Corp., have also promised to make certain that customers can get Plan B, even if a pharmacist doesn't want to provide the drug.

Scents in Bedroom May Help Improve Memory
A familiar scent in the bedroom while you get a good night's sleep may help boost memory, says a German study published Friday in the journal Science.
But the study found that the scent-aid only worked for certain kinds of memory and only during one stage of sleep, which means it's not likely to help people seeking a quick memory lift, the Associated Press reported.
The study found that medical students who slept in rooms with a rose scent scored higher on a card memory test than those who weren't exposed to the rose scent -- 97 percent vs. 86 percent.
However, the memory improvement only occurred when the students were exposed to the rose scent during a deep stage of sleep called slow-wave sleep. There was no memory boost when the students were exposed to the scent during a lighter sleep phase called REM sleep, the AP reported.
However, the scent was not effective when the students tried a finger-tapping sequence memory test. This is likely because different parts of the brain are involved with different types of memory, the researchers said.

Oversight Needed for Bodies Donated for Research: Experts
The United States needs a universal oversight system to prevent illegal marketing of body parts from cadavers donated to science, say experts.
The issue made headlines this week with the arrest of a former University of California, Los Angeles, official and a middleman as part of a police investigation into illicit trafficking of parts harvested from bodies willed for research, the Associated Press reported.
The UCLA scandal first erupted three years ago.
"There was some hand-wringing after the UCLA case. But, at the end of the day, I don't think we've seen any serious attempts by Congress or state legislatures to wrestle with this issue," Arthur Caplan, a University of Pennsylvania bioethics professor, told the AP.
Tissues from cadavers are used in many kinds of medical procedures, and the demand for human body parts has soared in recent years. If all its parts are used, a human body can be worth six figures, according to experts.
It is illegal in the United States to sell body parts for profit, but suppliers can charge fees for the acquisition and handling of body parts, the AP reported.
A national clearinghouse operated by an independent group should be established to track and distribute bodies donated for research, said Todd R. Olson, an anatomy professor at the Albert Einstein College of Medicine in New York.
While it wouldn't eliminate illegal sales of body parts and tissues, it would still be an improvement over the existing patchwork of rules, Olson told the AP.

Snorers Can Rob Partners of 2 Years' Worth of Sleep
Snorers may be depriving their partners of two years worth of sleep over their lifetime, suggests a survey by the British Snoring and Sleep Apnea Association.
The survey of 2,000 adults found that about a third of them sleep with a snorer and lose about two hours of sleep per night. Based on an average relationship of 24 years, that works out to about two years of lost sleep, BBC News reported
About half of the respondents said that snoring affected their sex lives, and 85 percent said their relationship would be better if their partner's snoring problem was resolved.
"Snoring can have a very negative impact on people who have to live with it," said association co-founder Marianne Davey.
"Lack of sleep can have a negative consequence on your physical, mental and emotional health. Poor sleep is linked with poor academic performance, increased risk of obesity and type 2 diabetes, divorce, suicide -- the list goes on and on," a spokesman with the British Sleep Society told BBC News.
