Light Up Your Health

 

Being outside in the sun makes you feel good - and is really good for your health! Let’s face it – we all love it when the winter is over and the warm sunshine comes around again and turning your face to the sun makes you feel a whole lot better.

This is because sunlight triggers an increase in the feel-good brain chemical serotonin. Serotonin controls sleep patterns, body temperature and your sex drive, and also lifts your mood and wards off depression.

Some people are extra sensitive to the lack of sunshine in the winter – so much so that they can suffer real depression called Seasonal Affective Disorder (SAD). Prescription drugs like Prozac stimulate the brain to produce more serotonin but many SAD sufferers usually resort to an artificial light box instead as Prozac can have unpleasant side effects.

Bacteria May Reduce Risk For Kidney Stones

 

Researchers from Boston University's Slone Epidemiology Center have found that the bacteria Oxalobacter formigenes (O. formigenes), a naturally occurring bacterium that has no known side effects, is associated with a 70 percent reduction in the risk of recurrent kidney stones. These findings appear online in the March issue Journal of the American Society of Nephrology.

Kidney stones are an important health problem in many countries. In the United States, the lifetime risk for developing a stone is five to 15 percent, and a five-year risk for recurrence is 30 to 50 percent. The economic impact of hospital admissions for this condition is $2 billion per year.

According to the researchers, up to 80 percent of kidney stones are predominately composed on calcium oxalate (CaOx) and urinary oxalate is a major risk factor for CaOx stone formation. O. formigenes metabolizes oxalate in the intestinal tract and is present in a large proportion of the normal adult population.

Listening To Cell Phones Impairs Driving, Study

 

Scientists in the US have shown that listening to a cell phone while driving was enough distraction to cause drivers to make the same type of driving errors as they would under the influence of alcohol.

The study is the work of neuroscientist Dr Marcel Just and colleagues at the Center for Cognitive Brain Imaging at Carnegie Mellon University in Pittsburgh, Pennsylvania, and is to be published shortly in the journal Brain Research.

Even if you are not talking, just listening to a cell phone conversation can significantly reduce the amount of brain activity associated with driving, said the researchers, who asked volunteers to drive on a simulator while they observed their brains using an MRI (magnetic resonance image) scanner.

Using cell phones while driving has been a matter of controversy for some time, but this is the first study to look at listening alone as a distraction.

Americans Sleepier Than Ever

 

MONDAY, March 3 (HealthDay News) -- Americans are working later and sleeping less, a dangerous combination which can cause drowsiness at the wheel, loss of productivity and a lack of interest in sex.

And while most people know this is a problem, about two-thirds of them aren't doing anything about it, a new poll shows.

"People are actually acknowledging it's an issue and not doing any thing about it," said Mark R. Rosekind, a former board member of the National Sleep Foundation (NSF). "This can be lethal in your car."

The troubling numbers come from a new Sleep in America poll released Monday by the NSF as part of its 11th annual National Sleep Awareness Week.

This year's survey focuses much more on the workplace and issues of safety and productivity than previous surveys, said Rosekind, who was on the poll task force.

Colonoscopies Could Miss Dangerous Lesions: Report

More Than 9 Percent of Dangerous Lesions May Be Missed

Mar 5, 2008

WASHINGTON (Reuters) - The most dangerous types of pre-cancerous lesions in the colon could be missed by colonoscopies, researchers cautioned on Wednesday.

More than 9 percent of the growths that could become tumors are flat and difficult to see, the team at the Veterans Affairs Palo Alto Health Care System in California found.

Colonoscopies are examinations of the colon that use an endoscope -- a little camera on a flexible tube. The doctor doing the examination can see and remove polyps, the small growths that can become tumors.

But not every pre-cancerous lesion stands up. There is a type called a flat, non-polypoid colorectal neoplasm and the California team found they are both more common and more dangerous than previously thought.

Dr. Roy Soetikno and colleagues examined the results of 1,819 colonoscopies among patients at their hospital.

They found 170 of these flat lesions, or 9.35 percent of all growths detected.

Once removed, they were 10 times as likely as the more obvious growths to contain cancerous tissue, Soetikno's team reported in the Journal of the American Medical Association.

Rare Gene Mutation Plays Role in Longevity

 

TUESDAY, March 4 (HealthDay News) -- A rare gene mutation that restricts a particular growth factor may be one of the keys to living to 100 and beyond, a new study suggests.

This mutation, which seems to decrease the activity of insulin-like growth factor (IGF-1), results in short stature but longer life. Exactly why this might lengthen someone's life isn't known, but the researchers say the finding might prove useful in developing anti-aging drugs.

"We found that people of a hundred years old have mutations in a gene that is related to the growth hormone pathway," said lead researcher Dr. Nir Barzilai, director of the Institute for Aging Research at the Albert Einstein College of Medicine in New York City. "We think this is important, because that's what now happens in nature. The pony lives longer than the horse, the small dog lives longer than a large dog. Apparently, it's true for humans also."

Interestingly, this particular mutation has been found mostly among women, he added.

It might be possible, given these findings, to develop drugs that can prevent aging and age-related disease, Barzilai noted. "There are drugs being developed to decrease growth hormone in patients with tumors, because sometimes cancer is dependent on growth hormones," he said. "Maybe we can adopt the strategy to slow aging."

Perceptions: Watch Your Weight, Sure, but Don’t Worry About It

Worrying about weighing too much may be bad for you, no matter how much you actually weigh.

 

Using results from a telephone health survey run by the Centers for Disease Control and Prevention, researchers analyzed data on more than 170,000 men and women nationwide. Among other information about health and lifestyle, all reported height and weight, how much they would like to weigh and how many days in the past month they had felt physically or mentally unhealthy.

The study, to be published in the March issue of The American Journal of Public Health, found that men who wanted to lose 1 percent, 10 percent and 20 percent of their body weight reported 0.05, 0.9 and 2.7 unhealthy days a month, respectively. Women with the same weight-loss desires reported 0.1, 1.6 and 4.3 total unhealthy days a month. The results held even after controlling for age and body mass index.

The authors acknowledge that their findings depend on self-reports, and that women tend to say they weigh less than they do, while men claim to be taller than they are. But controlling for many variables — like diabetes, hypertension and smoking — did not significantly alter the conclusions.

Hormone users face new cancer risks years later

 

CHICAGO - The first follow-up of a landmark study of hormone use after menopause shows heart problems linked with the pills seem to fade after women stop taking them, while surprising new cancer risks appear.

That heart trouble associated with hormones may not be permanent is good news for millions of women who quit taking them after the government study was halted six years ago because of heart risks and breast cancer.

But the new risks for other cancers, particularly lung tumors, in women who’d taken estrogen-progestin pills for about five years puzzled the researchers and outside experts. Those risks “were completely unanticipated,” said Dr. Gerardo Heiss of the University of North Carolina in Chapel Hill, lead author of the follow-up analysis.

The analysis focused on participants’ health in the first two to three years after the study’s end. During that time, those who’d taken hormones but stopped were 24 percent more likely to develop any kind of cancer than women who’d taken dummy pills during the study.

“There’s still a lot of uncertainty about the cause of the increased cancer risk,” said analysis co-author Dr. JoAnn Manson, chief of preventive medicine at Harvard’s Brigham and Women’s Hospital.

The cancers included breast tumors, which also occurred more frequently in hormone users during the study.

The researchers noted that the increased risks for all cancers amounted to only three extra cases per year for every 1,000 women on hormone pills, compared with nonusers.

Blood Thinner Might Be Tied to More Deaths

 

By WALT BOGDANICH

Published: February 29, 2008

Amid indications that more people may have died or been harmed after being given a brand of the blood thinner heparin, federal drug regulators said Thursday that they had found “potential deficiencies” at a Chinese plant that supplied much of the active ingredient for the drug.

Baxter International, which makes the brand of heparin associated with the problems, and buys supplies from the Chinese plant, announced that it was expanding a recall to include virtually all its heparin products. Though Baxter produces much of the heparin used in the United States, regulators said the other major supplier would be able to meet the demand.

The Food and Drug Administration said the number of deaths possibly associated with the drug, made from pig intestines, had risen to 21 from 4. But it cautioned that many of those patients were already seriously ill and that the drug might not have caused their deaths.
