And It’s Less Invasive

1 At-Home Glaucoma Test Developed

A new easy-to-use, hand-held probe has been developed by engineer Eniko Enikov, U of AZ, to detect glaucoma. The instrument, which can be used at home, may soon replace cumbersome tests given at the ophthalmologist’s office. "You simply close your eye and rub the eyelid like you might casually rub your eye," says Enikov who adds, "The instrument detects the stiffness and, therefore, infers the intraocular pressure." Enikov, who worked with ophthalmologist Dr. Gholan Peyman, is seeking investors to help fund final development and commercialization of the prototype probe. Glaucoma is the leading cause of blindness and affects more than 4 million Americans, it’s estimated by the Glaucoma Research Foundation, of this often symptomless and incurable, but manageable, disease.

Obesity at 9 Months

2 Third of U.S. Babies Are Too Fat

Obesity may begin much earlier than previously thought as a new study reveals that 32 percent of babies were overweight or obese by the time they reached 9 months old. The study by Wayne State University researchers involved more than 7,500 infants from across the U.S., and was published in the American Journal of Health Promotion. According to the findings, by the time the infants reached 2 years old, 34 percent were overweight. Some of the overweight babies at 9 months were normal weight by 2 years, and some of the normal weight babies gained too much by age 2. Parents with overweight infants should consider food "quality and quantity," especially portion size, says MSNBC. Experts say minor tweaks to a baby's diet can make a big difference, including eliminating just 150 calories a day.

3 Researchers Develop Vaccine Against Cocaine

While a newly developed cocaine vaccine needs further study before it can be used in humans, it has created a long-lasting anti-cocaine immunity in mice, say researchers from The Scripps Research Institute, Weill Cornell Medical College and Cornell University. The vaccine combines pieces of common cold virus and a particle that can mimic cocaine. "The vaccine suppresses the stimulant effects of the drug," said Scripps Research Professor Kim Janda. Researchers believe that the novel vaccine strategy could provide a simple way for addicts to break their habit. The same approach may also be useful for other addictions, such as nicotine, heroin and methamphetamine.

Not the Size of Texas

4 Plastics in Ocean Not As Bad As Media Says

The "Great Garbage Patch" between California and Japan isn't as large as the media has portrayed, claims Angelicque "Angel" White, an assistant professor of oceanography at Oregon State. According to White, claims that the floating patch of garbage is double the size of Texas are grossly exaggerated. White says that "... using the highest concentrations [of plastic] ever reported by scientists produces a patch that is a small fraction of the state of Texas, not twice the size." According to White, it would be "prohibitively costly" to remove the plastic in the ocean. She suggests that we concentrate on preventing more plastic from entering the ocean.

Health Reflected in Walking Pace

5 Walking Speed May Predict Years Left

Survival for seniors may be predicted by walking pace, say researchers who studied nearly 35,000 adults aged 65 and older. The large study in Journal of the American Medical Association reveals that the higher a senior's walking speed, the longer that person is expected to live. A 70-year-old man with a 2.5 mph walking speed is expected to live an average eight years longer than if he had a 1 mph walking pace; however, a woman would live 10 years longer, reports CNN. For a 70-year-old woman, the difference between walking 3 mph or 3.5 mph is six to seven years on average, but only four years for a man. Researchers say seniors shouldn't try to increase their natural walking pace, which is a reflection of how the body's systems are working.

Curing Baldness Not Hopeless

6 Male-Pattern Baldness Traced to Stem Cells

An underlying cause of male-pattern baldness may be the inability of stem cells located in the scalp to turn into cells that create hair follicles, suggest researchers from the University of Pennsylvania. Reporting in Journal of Clinical Investigation, scientists are hopeful that the new findings could lead to a treatment for male-pattern baldness. Scientists had previously believed that bald people experience a depletion of hair follicle stem cells. According to MSNBC, the new study reveals that bald people have the same number of hair follicle stem cells as others. Yet, the stem cells may need some coaxing to produce more hair follicle progenitor cells.

Find a Registered Dietitian

7 Doctors Are Weak in Nutrition and Diet Advice

Did you make a resolution to lose weight and need advice on what your next steps should be? Probably not a good idea to ask your doctor, says Orly Avitzur MD, medical advisor to Consumers Union. During medical school, doctors receive very little training in the area of nutrition. Most only meet the minimum of 25 hours set by the National Academy of Sciences, according to the Association of American Medical Colleges. And don’t rely on the internet for help either. A separate survey finds that most people search for health topics online to self-diagnose, but only a fourth actually check for reliable sources. While your doctor should be the first to know of your weight loss efforts, especially if you have a chronic medical condition, get your practical advice from a registered dietitian.

No Illnesses Reported

8 Hepatitis Exposure from Communion Feared

Hundreds of people may have been exposed to Hepatitis A while receiving communion on Christmas Day at Our Lady of Lourdes Church on Long Island, New York. At least one of the clergy members involved with the communion process was infected with the disease. Though about 1300 people were in attendance at church services that day, there have been no reports of illness. Symptoms of Hep A include fever, fatigue, nausea, poor appetite, stomach pain, dark-colored urine and jaundice. The Nassau County Department of Health is offering vaccines to those received communion during the 10:30 am and noon Masses. Those exposed should receive vaccination within two weeks of exposure, according to a statement released.

9 Energy Drinks Could Increase Anxiety, Depression

New research from Oklahoma State University suggests that consuming energy drinks early in life may make some more prone to anxiety, depression and addictive behaviors later on. Dr. Conrad Woolsey calls the drinks a “pharmacological Molotov cocktail.” Because the human brain does not fully develop until age 25, it is more susceptible to being affected by the ingredients in the pumped-up soft drinks. Energy drinks often contain additives such as taurine and inositol which are used in some anti-anxiety and antidepressant medication. When taken alongside a stimulator, like caffeine or guarana, they can affect the action of neurotransmitters in the brain. Overstimulation of stress neurotransmitters early in life can cause them to be overactive later, leading to anxiety and depression.

Some Decent Low Price Options

10 Consumer Reports Rates Home Exercise Equipment

This is the time of year when many consumers purchase home exercise equipment, either due to New Year’s resolutions or taking their exercise indoors due to cold weather. Consumer Reports has tested 67 treadmills and elliptical trainers in a wider range of prices and rated them for their upcoming February issue. While paying more will likely get you more features or sturdier construction, there are good options even at the lower price levels. The top-rated non-folding treadmill is the Precor 9.31 priced at $3,300, the top rated folding treadmill is the Horizon T202 at $800, and the top-rated elliptical trainer is the Diamondback 1260Ef priced at $2,200. Those in the “Best Buy” category include the PaceMaster Platinum treadmill and the Nautilus E514 elliptical.
