May Yield New Treatment

1 New Culprit Implicated in Chronic Back Pain

An immune cell may play a major role in back pain resulting from disc disease, says William J. Richardson, MD, Duke University Medical Center. This discovery may spur treatments in the management and possible prevention of degenerative disc disease, reducing the need for back surgery. "Mechanical forces may initiate the degenerative process, but biochemical inflammatory changes certainly play a role in disc pathology," says author Dr. Mohammed Shamji. It was thought that disc pain pain results when the outer layer of cartilage ruptures and some of the inner material protrudes into the spinal canal and touches a nerve. Now it’s believed that pain is due to an immune response from inflammatory cells. Doctors are several steps away from human studies but the research is promising.

But They Don’t Like It

2 Older Adults Watch More TV Than Kids

Researchers at the Stein Institute for Research on Aging and Rady School of Management at the University of California, San Diego School of Medicine found that older people watch considerably more television than young people - and they enjoy it less. In a survey of 3092 Americans, ages 15 to 98, adults over 65 reported watching three times more television than younger adults. In addition, older adults correlated tv watching with lower satisfaction than they’d get from socializing or other leisure activities. Research has already shown that the average American household spends 4.5 hours per day watching television. But, in adults 65 and older, that time increases to 25 percent of their day. Excessive tv watching is associated with a greater risk for diabetes and dementia.

Gold or Also-Ran?

3 Caffeine Boosts Athletic Performance

While caffeine isn't a substance prohibited for use by competing athletes by the World Anti-Doping Agency (WADA), perhaps it should be. According to new research by scientists from the UK's Coventry University, high doses of caffeine may directly increase endurance and muscle power. The research reveals that caffeine improves muscle performance during sub-maximal activities, such as running a marathon. "A small increase in performance via caffeine could mean the difference between a gold medal in the Olympics and an also-ran," says lead researcher, Dr. Rob James. High doses of caffeine are obtained via powder, tablets or concentrated liquid.

Third Lower Sperm Counts

4 Mother's Drinking May Affect Son's Sperm

A new observational study shows that mothers who consume 4.5 or more drinks during pregnancy have sons with lower sperm concentrations, reports MSNBC. According to the new research by the University of Aarhus in Denmark, men around 20 years old who had mothers who moderately consumed alcohol during pregnancy had sperm concentrations that were a third lower than men who weren't exposed to alcohol before birth. Researchers measured a drink as 12 grams of alcohol, which is equal to a 120 ml glass of wine, 330 ml can of beer, or a 40 ml shot of spirits. While the study showed an association between drinking moderately during pregnancy and low sperm count in sons, researchers are unable to say for certain if alcohol caused the lower sperm concentrations observed in the study.

Roaches Invade Air Caterer

5 Airline Food May Be Unsanitary

Food and Drug Administration inspectors have found numerous safety violations at a large airline food caterer, including live roaches and rodent feces, reports USA Today. Inside LSG Sky Chefs, the largest airline caterer in the world, the FDA found live roaches and dead roach carcasses that were "too numerous to count." They also found employees handling food with their bare hands, as well as the dangerous bacteria Listeria on the kitchen floor. An inspection of LSG Sky Chefs' Minneapolis facility last year revealed a mouse, nesting materials and rodent feces under a food pallet. Each year, LSG Sky Chefs provides 405 million meals for more than 300 airlines. Other airline caterers also violated safety regulations, including Gate Gourmet and Flying Food Group.

Antibodies Against All Strains

6 Universal Influenza Antibodies Discovered

Researchers in Madison, WI and Seattle, WA have found that people develop rare antibodies against all strains of influenza. The antibodies were identified and made in large quantities and mice infected with lethal doses of H1N1 and H5N1 after being treated with antibodies. Sixty to 80 percent of the mice treated with antibodies recovered versus only 10 percent of the untreated control group. They attack parts of the virus present in most or all strains that do not change much as other parts, which could eliminate resistance to any new treatment that may be developed. Researchers are excited about the results and Yoshihiro Kawaoka, who was involved in this study, said "Such antibodies may be especially useful during outbreaks of newly emerging, highly pathogenic influenza viruses."
