Texas Gov. Rick Perry (R) says that it's just a coincidence that he and eight other lawmakers received donations of $5,000 each from Merck lobbyists just a few days before mandating the drug giant's HPV cervical cancer vaccine for all females in Texas ages 12 and up.
A Pennsylvania family is suing ConAgra, claiming salmonella-tainted peanut butter led to the death of a family member.

Poisoning from prescription drugs has risen to become the second-largest cause of unintentional deaths in the United States, according to the federal Centers for Disease Control and Prevention.
In its Morbidity and Mortality Weekly Report, researchers found that deaths from prescription drugs rose from 4.4 per 100,000 people in 1999 to 7.1 per 100,000 in 2004.
This increase represents a jump from 11,000 people to almost 20,000 in the span of five years.

A hormone produced during pregnancy could reverse some of the neurological damage associated with multiple sclerosis, a mouse study suggests.
The finding could help explain why women with MS suffer fewer symptoms during pregnancy. And the results suggest that the hormone - prolactin - might one day be used to treat people with the disorder.
Multiple sclerosis involves the destruction of the sheath of fatty tissue called myelin that normally protects nerve cells. The loss of this protective layer disrupts nerve signalling and leads to symptoms including loss of coordination.

Drinking caffeinated beverages on a regular basis may provide significant protection against death from heart disease in the elderly who have normal levels of blood pressure, according to data from a large U.S. health and nutrition study.
Drinking caffeinated beverages may induce a "healthy" rise in blood pressure that counteracts the drop in blood pressure that occurs after a meal, a phenomenon that becomes more pronounced as people age, researchers note.
Among 6,594 adults participating in the study, 426 died of heart disease during a 9-year period. For subjects 65 years of age or older, the researchers found that greater daily consumption of caffeinated beverages was associated with a lower risk of death from heart disease. This acted in a dose-response fashion - the higher the caffeine level, the lower the risk, and visa versa.

A mathematical model of disease cycles developed at the University of Michigan shows promise for predicting cholera outbreaks.
Speaking in a symposium titled "New Vistas in the Mathematics of Ecology and Evolution" at the annual meeting of the American Association for the Advancement of Science in San Francisco, theoretical ecologist Mercedes Pascual discussed how models that she and coworkers have developed can aid short-term forecasting of infectious diseases, such as cholera, and inform decisions about vaccination and other disease-prevention strategies.
In research done over the past seven years, Pascual and colleagues have found evidence that a phenomenon known as the El Nino-Southern Oscillation (ENSO), a major source of climate variability from year to year, influences cycles of cholera in Bangladesh. They also showed that the coupling between climate variability and cholera cycles has become stronger in recent decades.

Washington- Drugs prescribed to treat attention deficit hyperactivity disorder will include guides to alert patients and parents of the risks of mental and heart problems, including sudden death.
The Food and Drug Administration said Wednesday that it directed the manufacturers of Ritalin, Adderall, Strattera and all other ADHD drugs to develop the guides. In May 2006, the agency told manufacturers to revise the labels of the drugs to reflect concerns about the cardiovascular and psychiatric problems.
Draft versions of the guides posted on the FDA Web site include discussion of reports of increased blood pressure and heart rate in ADHD patients, as well as cases of sudden death in some who have heart problems and heart defects. In adult patients, the reported problems also include stroke and heart attack.
The alerts also cover psychiatric problems, such as hearing voices, unfounded suspicions and manic behavior, of which there is a slightly increased risk in patients who take the drugs, the FDA said. The guides also tell patients and their parents of precautions they can take to guard against the risks.

San Francisco -- A nice cup of the right kind of cocoa could hold the promise of promoting brain function as people age.
In an increasingly aging world, medical researchers are seeing more cases of dementia and are looking for ways to make brains work better.
One potential source of help may be flavanols, an antioxidant found in cocoa beans that can increase blood flow to the brain, researchers said Sunday at the annual meeting of the American Association for the Advancement of Science.
Ian MacDonald of England's University of Nottingham reported on tests given to young women who were asked to do a complex task while their brains were being studied with magnetic resonance imaging.
Among the women given drinks of cocoa high in flavanols, there was a significant increase in blood flow to the brain compared with subjects who did not drink the cocoa, he said.

U.S. Billionaire Bill Gates and Canadian Prime Minister Stephen Harper announced Tuesday a joint plan to finance the testing of possible AIDS vaccines.
The plan, named Canadian HIV Vaccine Initiative, is to receive 111 million Canadian dollars (94.3 million U.S. dollars) from Ottawa and 28 million Canadian dollars (23.8 million U.S. dollars) from the Bill and Melinda Gates Foundation.
