COPD Tied to Tiny Brain Bleeds, Study Finds
by Robert Preidt, HealthDay Reporter
Likelihood increases with illness severity, researchers say
July 19 (HealthDay News) -- People with the lung condition called chronic obstructive pulmonary disease (COPD) are at increased risk for bleeding in the brain, a new study finds.
Researchers looked at 165 people with COPD and 645 people with normal lung function and found that those with COPD were more likely to have what are called cerebral microbleeds.
The more severe a patient's breathing problems, the more likely they were to have microbleeds, according to the study, published online July 19 in the American Journal of Respiratory and Critical Care Medicine.

U.S. Blacks Still Lag Whites in Life Expectancy
by Steven Reinberg, HealthDay Reporter
Heart disease, cancer and murder main contributors to four-year disparity, experts say
July 18 (HealthDay News) -- Despite a significant increase in life expectancy in recent decades, black Americans still die almost four years earlier than white Americans do, federal health officials reported Thursday.
The disparity is largely due to higher death rates from cancer, diabetes, heart disease, murder and stroke, according to statistics released by the U.S. Centers for Disease Control and Prevention.
'iKnife' Tells Surgeon Whether Tissue Is Cancerous
by Dennis Thompson, HealthDay Reporter
But more research needed to see if device works in everyday practice, expert says
uly 17 (HealthDay News) -- An experimental surgical "knife" can accurately identify cancerous tissue as a surgeon cuts through it, creating the potential for shorter cancer surgeries that remove all traces of tumor, according to a study co-written by the device's developers.
The "iKnife" uses electricity to cauterize surgical incisions as they are made, and then samples the resulting smoke to determine whether the tissue being cut is healthy or cancerous.

Did Avoidance of Hormone Therapy Harm Certain Women?
by Kathleen Doheny, HealthDay Reporter
For older women without a uterus, estrogen may save lives, researchers say
uly 18 (HealthDay News) -- Widespread discontinuance of hormone replacement therapy in the past decade possibly contributed to the deaths of nearly 50,000 U.S. women who had had a hysterectomy, a new analysis contends.
The findings refer only to women who've had a hysterectomy and then experience menopausal symptoms, the researchers emphasized.
"In women who have had a hysterectomy who have symptoms of hormone deficiency [such as hot flashes], it can be lifesaving for them to take estrogen," said review author Dr. Philip Sarrel, of Yale University School of Medicine.

Alzheimer's Progression, Step by Step
by Barbara Bronson Gray, HealthDay Reporter
As researchers learn more, therapy might someday address brain changes much sooner
July 16 (HealthDay News) -- New research seeks to delineate just how Alzheimer's disease unfolds in the human brain.
Biological changes may happen earlier than scientists had previously thought, according to a new disease model. This suggests that early signs of risk could potentially become treatment targets long before symptoms of Alzheimer's begin to appear, the researchers said.
Divorce in Early Childhood May Harm Adult Ties
by Kathleen Doheny, HealthDay Reporter
If split happened when kids were young, they were less likely to feel secure later, particularly with fathers
July 16 (HealthDay News) -- If parents divorce when their children are young, the split can affect how secure these children will feel about their relationship with their parents as adults, new research shows.
"The disruptive consequences of parental divorce on the security of parent-child relationships are more acute when parental divorce takes place early versus later in a child's life," said study author R. Chris Fraley, a professor of psychology at the university of Illinois at Urbana-Champaign.

Living Long and Healthy After 65 Depends on State: CDC
by Steven Reinberg, HealthDay Reporter
Race also influences your healthy life expectancy, researchers say
July 18 (HealthDay News) -- Place and race influence healthy life expectancy at age 65, U.S. health officials said Thursday.
Blacks across the country and whites in the South have the lowest healthy life expectancy after age 65, according to 2007-2009 data analyzed by the U.S. Centers for Disease Control and Prevention (CDC). Healthy life expectancy refers to healthy aging, or the number of years lived without disability.
"Our data show there is a disparity by race and region in healthy aging," said Paula Yoon, acting director of CDC's Epidemiology and Analysis Program Office and report co-author.

Stair-climbing, other everyday tasks were harder for those with deficiency, researchers found
July 17 (HealthDay News) -- Older people with vitamin D deficiency may struggle with daily physical activities such as dressing or climbing stairs, a new study shows.
It's estimated that as many as 90 percent of older people are vitamin D-deficient. The vitamin, usually absorbed through sunlight or diet, plays a key role in bone and muscle health, and a deficiency can lead to reduced bone density, muscle weakness, osteoporosis and broken bones.
Delaying Retirement May Help Stave Off Alzheimer's
by ?Maureen Salamon, HealthDay Reporter
Study looked at self-employed workers in France
July 15 (HealthDay News) -- As Americans increasingly delay retirement, a new French study indicates this scenario may have a silver lining: a lower risk of developing Alzheimer's disease.
Researchers analyzing health and insurance records of more than 429,000 self-employed workers found a 3 percent reduction in dementia risk for each extra year at the age of retirement. Workers evaluated had been retired for an average of more than 12 years, and 2.65 percent of the group had dementia.

by Alan Mozes, HealthDay Reporter
Results, if confirmed, might point to new treatments
uly 15 (HealthDay News) -- If battling a deadly disease can be said to have a silver lining, this might be it: Many forms of cancer appear to lower the risk for developing Alzheimer's disease, new research suggests.
After sifting through the health records of nearly 3.5 million patients, investigators concluded that most kinds of cancer seem to confer some degree of protection against Alzheimer's, reducing risk of the age-related brain disorder by anywhere from 9 percent to 51 percent.
Diabetes Drug May Protect the Brain
by Serena Gordon, HealthDay Reporter
Study found patients taking metformin were 20 percent less likely to develop dementiaJuly 15 (HealthDay News) -- The diabetes drug metformin may do more than help control blood sugar levels: New research suggests it may also reduce the risk of dementia.
Compared to people taking another class of diabetes medications called sulfonylureas, those taking metformin had a 20 percent reduced risk of developing dementia over the five-year study period.
"Metformin could have a possible neuroprotective effect in the brain," said study author Dr. Rachel Whitmer, an epidemiologist in the division of research at Kaiser Permanente in Oakland, Calif.

Is a Gluten-Free Diet Right for You?
by Serena Gordon, HealthDay Reporter
Candidates include people with celiac disease, gluten sensitivity or those with a wheat allergy
July 19 (HealthDay News) -- Chances are you know at least one person who's given up eating gluten. Maybe you've even given it up yourself. But who can really benefit from a gluten-free diet?
"Gluten is one of the main proteins found in wheat, barley and rye," said Dr. Joseph Levy, division director of pediatric gastroenterology at NYU Langone Medical Center in New York City. "It's actually a group of proteins and not a single component, but gluten is the general term."
Calorie Advice on Menus Might Not Help People Eat Better
by Alan Mozes, HealthDay Reporter
Customers may resist doing the math with every meal, study author says
July 18 (HealthDay News) -- Making general calorie consumption guidelines available to patrons of restaurants where calorie count labels are already on the menu does not lead to better food choices, new research cautions.
"The general inability of calorie labeling to result in an overall reduction in the number of calories consumed has already been pretty widely shown," said study lead author Julie Downs. "So that's nothing new. But in the face of that, there has been the growing thought that perhaps the problem is that people don't know how to use the information without some framework, some guidance," she explained.
Your Smartphone May Be Making You Fat
by Barbara Bronson Gray, HealthDay Reporter
Heavy use tied to sedentary lifestyle, less fitness in study of college students
July 18 (HealthDay News) -- Smartphone users just might be the new couch potatoes.
Researchers studying college students found that cellphone use -- much like watching television -- may significantly decrease physical activity and fitness levels.
"Using a cellphone doesn't have the same kind of negative stigma that sitting on the couch and watching TV has, but it can be just as bad for you," said study co-author Jacob Barkley, an associate professor of exercise science at Kent State University in Ohio.
Regular, Vigorous Exercise May Lower Stroke Risk
by Randy Dotinga, HealthDay Reporter
Direct effect not shown in study, but experts say physical activity's impact is clear
July 18 (HealthDay News) -- Exercising enough to break a sweat most days might slightly reduce the risk of stroke in middle-aged and older people compared to those who are inactive, a new study suggests -- although the findings aren't definitive and the difference may be insignificant.
Still, the study results indicate that "you can control your destiny with regards to stroke," said study lead author Michelle McDonnell. "A healthy diet, healthy body weight, regular exercise along with a moderate alcohol consumption and not smoking combined can reduce your risk of stroke by 80 percent. Here we show that regular physical activity is an important aspect of that and should be encouraged."
As Years Spent Obese Rise, So Do Heart Risks
by Steven Reinberg, HealthDay Reporter
Study strengthens link between excess pounds and cardiovascular troubles
July 16 (HealthDay News) -- There's more bad news for overweight Americans: A 30-year study finds the risk for heart disease rises the longer someone is obese.
"Each year of obesity was associated with about a 2 to 4 percent higher risk of subclinical coronary heart disease," said study lead author Jared Reis, an epidemiologist with the U.S. National Heart, Lung, and Blood Institute.
"Subclinical" heart disease means damage to arteries that shows up in markers such as calcium buildup on arterial walls, but has not yet developed into symptomatic illness.
Could a Gene Help Make You Obese?
by Dennis Thompson, HealthDay Reporter
Certain DNA might keep people hungry, study suggests
July 15 (HealthDay News) -- Researchers have discovered a potential genetic explanation for why some people overeat and run a greater risk for obesity.
People who carry two copies of a variant form of the "FTO" gene are more likely to feel hungry soon after eating a meal, because they carry higher levels of the hunger-producing hormone ghrelin in their bloodstream, an international team of scientists found.
