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.

New research gives more ammunition to those hoping to change federal marijuana policy.
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.

Petersburg, VA - What you can't see, can hurt you. Just ask James P. Hilton a 45 year old paramedic educator turned freelance journalist. In his newly launched book, Playing With Fire: What Everyone Needs To Know to Protect Their Health From X-rays Hilton claims airport Backscatter x-ray machines, sometimes called "virtual strip searches" for their ability to allow security men to see beneath people's clothing, are setting the stage for a future epidemic of cancer.
In 2005, when government scientists tested 60 soft, vinyl lunch boxes, they found that one in five contained amounts of lead that medical experts consider unsafe _ and several had more than 10 times hazardous levels.

The American Psychological Association (APA) suggests that the proliferation of sexual images of girls and young women in the media is harming their self-image and development.
An APA Task Force on the Sexualization of Girls examined research papers covering the effect of all kinds of media content including television, music videos, magazines, video games, the Internet, movies, and music lyrics. They also looked at the way products are sold and advertised to young girls.
The Task Force described sexualization as: "when a person's value comes only from her/his sexual appeal or behavior, to the exclusion of other characteristics, and when a person is sexually objectified, e.g., made into a thing for another's sexual use."

Reacting to a furor in public health circles, Merck said Tuesday that it would stop trying to get state legislatures to mandate the use of its new cervical cancer vaccine.
At least 20 states are considering making use of the vaccine mandatory for schoolgirls, and the governor of Texas, Rick Perry, has already done so through an executive order. Part of the state rush to embrace the new vaccine has been fueled by Merck lobbying that began even before federal regulators approved the product last year.
The vaccine is aimed at a sexually transmitted virus that causes cervical cancer. Critics of the vaccine's use on moral and other grounds have used Merck's perceived influence as a weapon to fight its use. And even public health officials who favor the vaccine say the movement to make it mandatory has come too fast, provoking a backlash that could undermine its eventual widespread use.

Thousands may have been exposed recently to hepatitis A at a Pappasito's Cantina on Houston's north side, and shots are being offered to those who may have been infected.
Because hepatitis is contagious, the Harris County Department of Public Health is offering free shots of "immune globulin." However health officials say the shot only works for those who've come in contact with hepatitis within the previous two weeks. After that, anyone possibly exposed should watch for symptoms of fever, nausea, vomiting, exhaustion. Anyone who experiences such symptoms should see a doctor.

Comment: "Our goal is to prevent cervical cancer," - No, their goal is to make money - pure and simple - and in a United States owned and run by corporations, they are taking the logical next step of legislating a future market for their drugs.
Also, Bloomberg reported that, "A group called the National Vaccine Information Center said yesterday that its analysis of reports to U.S. regulators found cases of serious side effects to Gardasil. One was Guillain-Barre Syndrome, a disorder in which the body's immune system attacks part of the nervous system."
