Broccoli to fight skin cancer?

A diet heavy in cruciferous vegetables, such as broccoli sprouts, has shown potential risk-reduction properties for colorectal, prostate and various other forms of cancer. Dr. Dickinson’s research currently focuses on how sulforaphane — a naturally occurring compound in broccoli with established chemopreventive properties — could possibly be used to help patients reduce their risk for skin cancer. What sets Dr. …

Learning from a virus: Keeping genes under wraps

The discoveries improve the chances of developing more targeted therapies in place of existing drugs, which do not always work or come with side effects. Experts estimate that 60 to 90 percent of the world’s population carry the human cytomegalovirus, or CMV, which is one of the eight herpes viruses that infect humans…

New theory uncovers cancer’s deep evolutionary roots

Davies and Lineweaver are both theoretical physicists and cosmologists with experience in the field of astrobiology — the search for life beyond Earth. They turned to cancer research only recently, in part because of the creation at Arizona State University of the Center for the Convergence of Physical Science and Cancer Biology. The Center is one of twelve established by the National Cancer Institute to encourage physical scientists to lend their insights into tackling cancer. The new theory challenges the orthodox view that cancer develops anew in each host by a series of chance mutational accidents…

Nearly all US states see hefty drop in teen births

NEW YORK – & The nation's record-low teen birth rate stems from robust declines in nearly every state, but most dramatically in several Mountain States and among Hispanics, according to a new government report. All states but West Virginia and North Dakota showed significant drops over five years. But the Mountain States of Arizona, Colorado, Idaho, Nevada and Utah saw rates fall by 30 percent or more. In 22 states, teen Hispanic birth rates plunged at least 40 percent, which was described as “just amazing,” by the report's lead author, Brady Hamilton of the Centers for Disease Control and Prevention. What's driving the declines? No one can say for sure. Experts believe the explanation is complicated and probably varies a bit from state to state. The national figure has been falling since 1991, aside from a brief interruption in 2006 and 2007. The CDC report released Thursday is based on birth certificates for 2007 through 2011. Last year, the CDC announced the overall improvement in teen births: a record low of 31 births per 1,000 teens ages 15 to 19. That compares to 42 births per 1,000 five years earlier. The new report focuses on state figures in 2011: -- Lowest rates are in New Hampshire, Massachusetts, Connecticut and Vermont, each with rates under 17 per 1,000. -- Highest rates overall continue to be in the South, led by Arkansas and Mississippi, each with rates of about 50 per 1,000. In Arkansas, the majority of teen births are to white moms. In Mississippi, the majority are black. -- White teens continue to have the lowest birth rate nationally -- about 22 births per 1,000. Black teens saw a larger improvement, but their rate was still more than twice the white rate, at 47 per 1,000. -- Overall, the Hispanic rate plummeted from 75 to 49 per 1,000, now virtually a tie with the black rate. The teen drop in the last five years coincided with an overall decline in births, which experts attribute to a weak economy that dampened enthusiasm for having children. Hispanic women have been part of that trend, possibly due to the economy and to illegal immigration crackdowns in some states that reduce the number of young Hispanic females entering the country from Mexico and other nations, said John Santelli, a Columbia University professor of population and family health. That means new immigrants are having less impact on birth statistics, and second- and third-generation families are having more influence. As time goes on, Hispanics -- like other immigrant groups before them -- tend to adopt American customs and practices. “There is more attention on education, career, and the future,” said Dr. Janet Realini, head of Healthy Futures of Texas, a San Antonio-based organization focused on preventing teen and unplanned pregnancies. Hispanic rates, though, continue to be much higher than those for blacks and whites in most of the states with the largest Hispanic populations, including California, Texas, New York, New Jersey, Arizona, Colorado, New Mexico and Georgia. Texas has the highest number of teen births in the nation, with nearly 43,000 in 2011. Nearly two-thirds were to Hispanic moms. The overall improvement, though, is something to celebrate, said Bill Albert, chief program officer of the National Campaign to Prevent Teen and Unplanned Pregnancy. “Geography, politics, or policy alone simply cannot explain the widespread declines,” Albert said in an email. “Credit goes to teens themselves who are clearly making better decisions about sex, contraception, and their future.”source : http://www.foxnews.com/health/2013/05/23/nearly-all-us-states-see-hefty-drop-in-teen-births/

Foster Farms recalls grilled chicken breast strips for containing allergens

SAN FRANCISCO – & California-based chicken producer Foster Farms is recalling about 6,165 pounds of its ready-to-eat grilled chicken breast strips because the strips contain wheat and soy -- known allergens -- which are not listed on the labels of its packages, federal agriculture officials said. The mislabeled packages were discovered when a customer complained, the U.S. Department of Agriculture's Food Safety and Inspection Service said in announcing the recall Tuesday. The problem occurred when labels for another chicken product that does not contain wheat or soy were inadvertently used, food safety inspectors and officials at Foster Farms said. There have been no reports of adverse reactions from the sale of the mislabeled products, officials said. The chicken breast strips being recalled were sold in 4.5-pound cases containing 12, 6-ounce trays of “Foster Farms Grilled Chicken Breast Strips Boneless & Skinless With Rib Meat 97% Fat Free,” with an identifying case code of “000606.” The recalled product bears the establishment number “P-20923” inside the USDA mark of inspection and a use-by date of “JUN 22 2013” printed on each tray. They were produced April 23 and were distributed to retailers in Arizona, California, Hawaii, Nevada, Oregon, Utah and Washington. Based in Porterville, Foster Farms is a family-owned company that has been operating since 1939, according to the company's website. In a statement, Fosters Farms spokeswoman Lorna Bush said “food safety is, and always has been, our top priority.”source : http://www.foxnews.com/health/2013/05/22/foster-farms-recalls-grilled-chicken-breast-strips-for-containing-allergens/

Could marijuana reduce diabetes risk?

There's an unexpected link between marijuana use and factors related to Type 2 diabetes that has medical researchers intrigued. Several studies have found that marijuana users take in more food calories than nonusers, but they still have lower rates of obesity and diabetes, and lower average body mass index (BMI) levels. In a new study, researchers investigated what effects marijuana and its active ingredient tetrahydrocannabinol (THC) might have on people's metabolism, especially insulin levels. [5 Diets That Fight Diseases] Insulin resistance an important risk factor for diabetes is a metabolic disorder that occurs when the body's cells cannot properly intake insulin. The American Heart Association estimates 35 percent of U.S. adults have metabolic disorders that include insulin resistance. To examine the link between THC and metabolism, researchers gathered the results of 4,657 adults from the National Health and Nutrition Examination Survey, a cross-sectional study administered annually by the Centers for Disease Control and Prevention. Of the study's participants, 579 were current marijuana users, 1,975 had used the drug in the past but not recently, and 2,103 had never tried marijuana. Researchers analyzed the participants' fasting insulin levels, cholesterol levels, insulin resistance and waist sizes. Multiple benefits seen The results showed that the current marijuana users had 16 percent lower fasting insulin levels than nonusers, and 17 percent lower insulin-resistance levels. Additionally, the regular users of marijuana had smaller average waist sizes, and higher levels of high-density lipoprotein (HDL) cholesterol, aka “good cholesterol.” “These are indeed remarkable observations that are supported by basic science experiments that came to similar conclusions,” Dr. Joseph Alpert, professor of medicine at the University of Arizona College of Medicine, Tucson, said in a statement. Interestingly, only the current users of marijuana (not the former users) experienced the positive results, suggesting that the effects of marijuana use on insulin and insulin resistance only occur after recent use. To test their results, which were published in the latest issue of The American Journal of Medicine, the researchers also adjusted for participants who had been diagnosed with Type 2 diabetes. Much more research needed “After we excluded those subjects with a diagnosis of diabetes the associations between marijuana use and insulin levels, [insulin resistance], waist circumference and HDL-C were similar and remained statistically significant,” Dr. Elizabeth Penner, a co-author of the study, said in a statement. “Is it possible that THC will be commonly prescribed in the future for patients with diabetes or metabolic syndrome alongside antidiabetic oral agents or insulin for improved management of this chronic illness? Only time will answer this question for us,” Alpert said in an editorial accompanying the article in the journal. “We desperately need a great deal more basic and clinical research into the short- and long-term effects of marijuana in a variety of clinical settings such as cancer, diabetes and frailty of the elderly,” Alpert wrote.
