High Doses of NSAIDs Raise Risk of Heart Failure

iStockphoto/Thinkstock(NEW YORK) -- New research shows that high doses of common pain relievers may increase your risk for cardiovascular issues.

Non-steroidal anti-inflammatory drugs -- known as NSAIDs -- are among the most common pain-relief medicines in the world, including aspirin, ibuprofen and naproxen. Millions of Americans take those drugs or the number of prescription painkillers classified as NSAIDs every day, but new research shows that use of NSAIDs can increase your risk of heart failure, perhaps even double it.

The study, published in The Lancet, analyzed studies including over 353,000 people and found that all of the NSAIDs together roughly doubled the risk of heart failure. The risk was highest among people who already had underlying risk factors for heart disease.

The researchers did point out that the overall risk is relatively small and that the true danger of NSAIDs is only seen in high doses. Anyone who frequently uses high doses of these pain killers is urged to speak to a doctor.

Aspirin, interestingly, works to prevent the formation of blood clots, which can cause heart attacks. Other NSAIDs do not work to prevent blood clots.

Bee Venom May Provide Protection Against HIV

iStockphoto/Thinkstock(NEW YORK) -- A toxin contained in bee venom may have the ability to prevent HIV infection when packaged properly.

Researchers at Washington University in Saint Louis, tested a specific delivery system of the toxin, called melittin, in lab dishes and found that "super-tiny blobs" of the bee venom component can attach to and destroy the HIV virus, according to Science News.

The nanoparticles of melittin selectively attached to the HIV virus and poked holes in its protein coat. The result, according to the study, was sharply diminished amounts of the virus.

The researchers also tested the toxin on cells from vaginal walls, due to the frequency of HIV entering the body through the vagina. The treatment being studied did not have any negative impact on the human cells because of protective structures attached to their outsides. According to Science News, the structures prevent the nanoparticles from attaching to healthy human cells.

The study, published in Antiviral Therapy, has a long way to go before a functional drug can be developed, but is exciting nonetheless. According to Science News, the nanoparticles must still be proven able to be produced in a uniform manner and would require adhesive properties to prevent the toxin from entering the bloodstream.

Nonetheless, Antony Gomes from the University of Calcutta in India told Science News, "There are very few reports available on venom-based treatment against viruses. This type of research has the potential to proceed further for product development.”

Study Finds Young Children Watch a Shocking Amount of TV

Comstock/Thinkstock(NEW YORK) -- How many hours of television are your children watching?  Probably more than you think.  Pediatricians have long been concerned about television exposure in childhood, as it can affect cognitive development and social abilities in children.  

Researchers in a new study published by the Journal of Medicine say they were "just shocked" at how often children were exposed to television. They said that on average, children between the ages of 8 months to 8 years are exposed to nearly four hours of background television daily.  Children from African-American families and the poorest families in the study group were exposed to even more at an average of 5.5 and 6 hours daily, respectively.  

The TV is often on in the background while parents cook or clean, eat or sleep, and when it’s on, pediatricians say kids pay less attention to everything else. The authors recommend turning off the TV at meal and play times, as well as when no one is watching.

Fat Research May Lead to New Treatments for Obesity

(NEW YORK) -- A recent study revealing that scientists have found a way to turn white, bad fat into brown, good fat, may lead to new obesity treatments, Health Day reports.
White fat stores energy, causing weight gain, while brown fat burns energy, preventing obesity, says the health news service. The fat caused by white fat cells that accumulates around organs in the belly has been linked to an increased risk of heart disease and diabetes, the researchers said. During the study, they found a way to make white fat take on the characteristics of brown fat by blocking vitamin A metabolism in white fat, according to Health Day.

These findings could lead to new ways to treat obesity and its complications. The study was published on Sunday, May 6 in the online edition of the journal Nature Medicine.
