USDA launches online tool to link farmers with nearby consumers

The U.S. Department of Agriculture has unveiled its newest tool to promote local food systems, an online instrument that lets viewers see what local and regional food projects are under way in their area and read case studies, watch videos and see pictures from the field.

The "Food Compass" is the latest effort in the "Know Your Farmer, Know Your Food" project, meant to expand the number of small, local farmers and ranchers who serve their communities. An interactive map lets viewers see USDA-supported projects related to local food systems in place across the country. That includes information about access to local meals, careers in agriculture and access to healthy food.

The written section includes stories about local food system projects, whether that pertains to farm-to-school, farm-to-hospital and farm-to-institution programs; local meat processing; hoophouses; urban farms; organic farms; and school gardens. Readers can see how people are putting their USDA funds to work to connect to their communities.

The compass notes that buying and selling food at the local, rather than mass consumer, level is a growing trend. In 2011, more than 85 percent of customers asked by the National Grocers Association said they chose to shop at a grocery store based in part on whether it carries food grown from local producers. More than 2,000 schools across the country have farm-to-school programs, and more than 7,000 American cities and towns have farmers' markets. The growing trend is a positive thing since it is "spurring job growth, keeping more farmers on the land and more wealth in rural communities," said Agriculture Secretary Tom Vilsack.

Effects of concussions outlast symptoms, UK prof finds; another study says they affect thinking of teenagers more than others

A University of Kentucky assistant professor has found that the effects of a concussion may last longer than the symptoms, a finding that could influence how and when athletes are allowed to get back into a game.

Scott Livingston (UK photo), director of the UK Concussion Assessment Research Lab, used an electrophysiological measurement to arrive at his conclusion. With 18 college athletes, he placed electrodes on a limb while a magnetic-stimulating device was put over their head. They then received a brief pulse of magnetic stimulation to their brain. The amount of time it took for the athlete's limb to receive the response from the brain after the stimulation was then recorded. Nine of tyhe athletes had gotten concussions in the past 24 hours and nine had not.

The athletes were evaluated for 10 days, based on self-reported symptoms such as memory loss, headache and confusion; a computerized neurocognitive test; and the electrophysiological measurement. While symptoms from the concussion were greater within 24 to 72 hours after the injury and lessened over time as measured by self-reporting and neurocognitive testing, electrophysiological measurements show physiological changes increased as symptoms decreased.

Further investigation is needed, "especially to assess how long the disturbances in physiological functioning continue after those initial 10 days post-injury," Livingston said. "But in the meantime, sports medicine personnel caring for concussed athletes should be cautious about relying solely on self-reported symptoms and neurocognitive test performances when making return-to-play decisions."

Meanwhile, a study at the University of Montreal has found that "Concussions affect the thinking of teenagers more than they do that of adults or children," reports Nancy Shute of National Public Radio. "But all three age groups show lasting problems with working memory after sports concussions." (Read more)

Compromise meds-for-meth bill clears committee; third drug-related bill to pass this week

Update, March 2: Just hours after the committee approved the bill, Senate Majority Leader Robert Stivers, R-Manchester, "declared its future uncertain," reports Jack Brammer for the Lexington Herald-Leader. Stivers said there is "a very successful lobbying campaign" against Senate Bill 3 and said he did not "want to subject lawmakers to continued pressure by the makers of pseudoephedrine," Brammer reports. Though he wouldn't call the bill dead for this year, Stivers said he would decide soon on whether he would continue to pursue the bill's future. (Read more)

The compromise bill that will require a prescription to buy pseudoephedrine after a monthly or annual limit is reached passed 7-4 in the Senate Judiciary Committee this afternoon.

Senate Bill 3 will allow people to buy up to 3.6 grams of the drug a month and a maximum of 15 grams per year. After those limits have been reached, patients will have to see a doctor to obtain a prescription for more. The intent of the bill is to curb methamphetamine production — pseudoephedrine is the key ingredient to make the drug.

Now, people are limited to buying 9 grams per month and 120 grams per year.

Today, the committee approved an amendment to the bill, which will allow patients to buy 7.5 grams per month if a doctor says that amount if required, which amounts to 90 grams a year under these special circumstances.

The bill also prevents anyone who has been convicted of any drug-related crime — whether the crime was related to meth or not — from buying pseudoephedrine without a prescription for five years.

Sen. Robert Stivers, R-Manchester, made an impassioned argument for the bill, which he introduced earlier this week. He said the compromise works because "any box you look on will tell you that you should take this for no more than 14 consecutive days without seeing a doctor." The 3.6-gram monthly allotment will allow for 14 days' use.

As for the criticism that the reduction won't be enough to cover whole families who may be suffering from allergies or cold, Stivers argued "anyone who is subjecting a child to this continuous use on a repetitive basis is not really taking care of the child or the symptoms that cause their problems."

Carlos Gutiérrez of the Consumer Healthcare Products Association, which represents makers of over-the-counter medicine, said it is "adamantly against" the compromise bill, saying "we feel very strongly about the rights of consumers to buy a legal product." He pointed out if a chronic allergy sufferer takes 1 pill a day, that adds up to 7.2 grams per month.

Sen. Tom Jensen, R-London, questioned Guetiérrez and had him confirm that 84 percent of people who buy pseudoephedrine use less than 15 grams of the medicine per month, according to 2010 figures. He further established that the remaining 16 percent of people are buying 60 percent of all the pseudoephedrine sold in Kentucky.

More Americans dying from hepatitis C than from AIDS

More people are dying in the U.S. from hepatitis C than from AIDS, a new report from the Centers for Disease Control and Prevention says. More than 3.2 million Americans have the hepatitis virus, which can cause chronic infection of the liver and eventually lead to liver failure.

Hepatitis C death rates climbed to almost 5 per 100,000 in 2007, from fewer than 3 per 100,000 in 1999. In the same time period, the HIV-AIDS death rate dropped to slightly more than 4 per 100,000 from more than 6 per 100,000.

"The declines in HIV reflect the accomplishments in building a public health response to the epidemic that improved screening and provided means of access to effective treatment," said Dr. John W. Ward, director of the Division of Viral Hepatitis at the CDC and author of the study. A similar program for hepatitis C would be similarly helpful, he said.

The disease is most commonly spread by exposure to infected blood. Intravenous drug abuse is the most common method of transmission, reports MedicineNet.com.

Ward said there is now a treatment "that was about 70 effective at clearing the virus from the body, but, he said, most infected people are unaware of their condition and do not receive treatment," reports Nicholas Bakalar for The New York Times. (Read more)
