Vitamin E Sends Mixed Messages

Vitamin E Sends Mixed Messages
One of the most powerful antioxidants is truly a double-edged sword, say scientists at Ohio State University who studied how two forms of vitamin E act once they are inside animal cells.

In the past couple of decades, a slough of studies has looked at the benefits of vitamin E and other antioxidants. While a considerable amount of this research touts the advantages of consuming antioxidants, some of the studies have observed that in certain cases, antioxidants, including vitamin E, may actually increase the potential for developing heart disease, cancer and a host of other health problems.

This study provides clues as to why this could happen, say Jiyan Ma, an assistant professor of molecular and cellular biochemistry, and his colleague David Cornwell, an emeritus professor of molecular and cellular biochemistry, both at Ohio State.

The two men led a study that compared how the two most common forms of vitamin E -- one is found primarily in plants like corn and soybeans, while the other is found in olive oil, almonds, sunflower seeds and mustard greens - affect the health of animal cells. The main difference between the two forms is a slight variation in their chemical structures.

In laboratory experiments, the kind of vitamin E found in corn and soybean oil, gamma-tocopherol, ultimately destroyed animal cells. But the other form of vitamin E, alpha-tocopherol, did not. (Tocopherol is the scientific name for vitamin E.).........

Marital Harmony And Heart Health

Marital Harmony And Heart Health
Hardening of the coronary arteries is more likely in wives when they and their husbands express hostility during marital disagreements, and more common in husbands when either they or their wives act in a controlling manner.

Those are key findings of a study of 150 healthy, older, married couples - mostly in their 60s - conducted by Professor Tim Smith and other psychology experts from the University of Utah. Smith was scheduled to present the findings Friday March 3 in Denver during the annual meeting of the American Psychosomatic Society, which deals with the influence of psychological factors on physical health.

"Women who are hostile are more likely to have atherosclerosis [hardening of the coronary arteries], particularly if their husbands are hostile too," Smith says. "The levels of dominance or control in women or their husbands are not correlation to women's heart health."

"In men, the hostility - their own or their wives hostility during the interaction - wasn't correlation to atherosclerosis," he adds. "But their dominance or controlling behavior - or their wives dominance - was correlation to atherosclerosis in husbands." Smith summarizes: "A low-quality relationship is a risk factor for cardiovascular disease."

Smith conducted the study with University of Utah psychology experts Cynthia Berg, a professor; Bert Uchino and Paul Florsheim, both associate professors; and Gale Pearce, a Utah postdoctoral fellow now on the faculty of Westminster College in Salt Lake City.........

Obese People Are More Sensitive To Pain

Obese People Are More Sensitive To Pain
Obese people may be more sensitive to pain than people who aren't obese, a new study suggests.

All of the older adults who completed the study had osteoarthritis of the knee, a disease that causes inflammation and extreme pain in the knees.

Participants were given a mild electrical stimulation on their left ankle to measure their pain reflex. The stimulus was given before and after the participants took part in a 45-minute coping skills training session that included a progressive muscle relaxation exercise.

The obese patients showed a greater physical response to the electrical stimulation than did the non-obese people, both before and after the training session. This indicates they had a lower tolerance for the painful stimulation despite reporting, in questionnaires, that they felt no more pain than non-obese people.

"The relaxation procedure helped both groups cope with pain," said Charles Emery, the study's lead author and a professor of psychology at Ohio State University. "Additionally, our tests showed both groups had higher physical pain thresholds after the relaxation session. But the obese participants still had a lower threshold for tolerating the pain".

Emery and colleagues presented their findings on March 4 in Denver at the annual meeting of the American Psychosomatic Society.........

Whites more likely than blacks to die soon after spouse's death

Whites more likely than blacks to die soon after spouse's death
White Americans are far more likely than their black counterparts to die soon after the death of a spouse, as per new research from Harvard University. The longitudinal study of 410,272 elderly American couples indicates that the "widowhood effect" -- the increased probability of death among new widows and widowers -- is large and enduring among white couples but undetectable among black couples, suggesting that blacks may somehow manage to extend marriage's well-documented health benefits into widowhood.

The results, by Harvard sociologists Felix Elwert and Nicholas A. Christakis, are reported in the recent issue of American Sociological Review, available March 1.

"The health effects of a spouse's death differ radically between blacks and whites," says Elwert, a doctoral student in sociology. "We found good evidence of the widowhood effect among white couples: Men were 18 percent more likely to die shortly after their wives' deaths, and women were 16 percent more likely to die shortly after their husbands' deaths. By contrast, the estimated effect of a black spouse's death on the mortality of his or her surviving spouse is essentially zero."

Upon marrying, blacks and whites appear to receive the same health benefits, which prior research has attributed to factors such as emotional support, economic well-being, caretaking when ill, enhanced social support and kinship, and the promoting of healthy behaviors and discouraging of risk-taking. Elwert and Christakis suggest such benefits may be longer-lasting for blacks, persisting even after a spouse's death.........

HPV Infection Is The Top Risk Factor For Cervical Cancer

HPV Infection Is The Top Risk Factor For Cervical Cancer
Human papillomavirus (HPV) was found to be the main risk factor associated with increased incidence of an unusual type of cervical cancer called cervical adenocarcinoma, as per a research studyin the March 1 issue of the Journal of the National Cancer Institute.

The incidence of cervical adenocarcinoma has increased in recent years, even in countries with widespread screening programs, with incidence doubling in relation to all other cervical cancers between 1973 and 1996. HPV is a well-established cause of cervical squamous cell cancer, the most common type of cervical cancer worldwide. Prior studies have suggested HPV may also cause cervical adenocarcinoma, but those studies were small and did not provide information on the role of other factors in the development of this cancer.

To investigate the links between HPV and cervical adenocarcinoma in a multicenter, international sample of women, Xavier Castellsague, M.D., at the Institut CatalĂ  d'Oncologia in Barcelona, Spain, and his colleagues conducted a pooled analysis of eight case-control studies of cervical cancer conducted in countries in Africa, South America, and Southeast Asia. Women had been interviewed to determine potential risk factors for cervical cancer, and all received a pelvic examination as well as testing for HPV and cervical cancer.........

Duty In Iraq Causes High Use Of Mental Health Services

Duty In Iraq Causes High Use Of Mental Health Services
About one-third of U.S. military personnel from the war in Iraq access mental health services after their return home, as per a research studyin the March 1 issue of JAMA.

The U.S. military has conducted population-level screening for mental health problems among all service members returning from deployment to Afghanistan, Iraq, and other locations. To date, no systematic analysis of this program has been conducted, and studies have not assessed the impact of these deployments on mental health care utilization after deployment, as per background information in the article. Such information is an important part of measuring the mental health burden of the current war and assuring that there are adequate resources to meet the mental health care needs of veterans returning from Iraq and Afghanistan.

Prior research conducted after other military conflicts has shown that deployment and exposure to combat result in increased risk of posttraumatic stress disorder (PTSD), major depression, substance abuse, functional impairment in social and employment settings, and the increased use of health care services.

Charles W. Hoge, M.D., of Walter Reed Army Institute of Research, Silver Spring, Md., and his colleagues conducted a study to determine the relationship between deployment to Iraq and Afghanistan and mental health care use during the first year after return home. The scientists analyzed the results of the Post-Deployment Health Assessment completed by Army soldiers and Marines between May 1, 2003, and April 30, 2004, on return from deployment to Afghanistan (n=16,318), Iraq (n=222,620), and other locations (n=64,967). Health care utilization and occupational outcomes were measured for 1 year after deployment or until leaving the service if this occurred sooner. The assessment screened for such conditions as posttraumatic stress disorder, major depression, and other mental health problems.........

Technology Helps Disabled Kids Find Their Voice

Technology Helps Disabled Kids Find Their Voice
Laptop computers that combine features from popular toys with innovative technology have rapidly accelerated the learning and communication ability of disabled children, Penn State scientists say. The technology could in the future be adapted to victims of major accidents and the elderly as well.

As per Janice Light, distinguished professor of communication sciences and disorders at Penn State, more than 2 million Americans are unable to use speech to communicate, and children are a major component of this population.

"Kids learn and communicate through speech by trying out new words and forming sentences," says Light. "f they can't do that due to problems such as autism, Down syndrome, and cerebral palsy, then it is going to be difficult to learn how to read and write, make friends, and communicate their needs".

Computer-based technology that provides speech output is increasingly being used to assist such children in communicating but Light feels it has still not fully served its purpose.

"The design of a number of of these systems is really based on how adults think, and the machines are complicated and children take years learning how to use them," adds Light, who presented her findings today (Feb. 20) at the 2006 annual meeting of the American Association for the Advancement of Science.........

Who Gets Better Service At Clothing Stores?

Well-dressed Women Get Better Service At Clothing Stores
If women want the best possible service at a clothing store, they had better be looking fashionable and well-groomed before they hit the mall.

A new study found that well-dressed and groomed women received the friendliest and, in some cases, fastest service from salesclerks.

Researchers secretly observed interactions between customers and salesclerks at three large-sized women's clothing stores, timing how long clerks took to greet customers, and rating the clerks' friendliness.

Customers whose clothes were rated as more fashionable and attractive, and who showed better grooming and make-up skills, received better service than those whose appearance was not rated as highly.

"How well-dressed you are is one indicator of your status, and how much money you have to spend," said Sharron Lennon, co-author of the study and professor of consumer sciences at Ohio State University.

"Salesclerks believe that a well-dressed person is more likely to buy, and that affects the treatment she receives".

Lennon conducted the study with Minjeong Kim, an assistant professor at Oregon State University, who did the work while a graduate student at Ohio State.

Their results were published in a recent issue of Clothing and Textiles Research Journal.........

Link Between Obesity And The Urban Environment

Link Between Obesity And The Urban Environment
Scientists at the Mailman School of Public Health are studying the link between the urban environment and how it might contribute to the cause or origins of obesity. In a study that will have wide-reaching applications, the Mailman School is one of 14 groups across the United States to receive funding from the National Institute of Environmental Health Sciences (NIEHS) to study the association between body size and the built environment.

Up until now, obesity research has focused on ways to change individual behavior but with obesity rates continuing to climb, scientists are now turning their efforts to the built environment and the interventions that might be effective in fighting the epidemic. Working with various city departments, Andrew Rundle, DrPH, assistant professor in the Department of Epidemiology at the Mailman School, and his research team, are gathering data on neighborhood features such as land use, density of bus and subway stops, availability of nutritious food, the location and quality of parks and recreation facilities -- even the number of trees on a street and the number of buildings with elevators -- that affect a person's diet and activity levels. Upon completion of the research, Dr. Rundle expects to have a large base of evidence linking the built environment to body size.........

AIDS Rates Alarming In Attijuana, Mexico

AIDS Rates Alarming Attijuana, Mexico
A study by scientists at the University of California, San Diego (UCSD) School of Medicine indicates that the rate of HIV/AIDS infection in Tijuana, Mexico is increasing, and much higher than had been previously estimated. The findings are based on data compiled by a team of scientists working in San Diego and Mexico to create a population-based model in order to estimate HIV infection rates.

The number of men and women aged 15 to 49 years who are infected with HIV may be as high as one in 125 persons, as per Kimberly C. Brouwer, Ph.D., Assistant Professor in UCSD's Division of International Health and Cross-Cultural Medicine and the Department of Family and Preventive Medicine. Brouwer's study would be reported in the March 1 issue of The Journal of Urban Health, a bulletin of the New York Academy of Medicine.

Located directly south of San Diego California, Tijuana is a city of 1.2 million people located amidst the busiest land border crossing in the world. Data in this study suggest that Tijuana's HIV infection rate may be close to three times higher than Mexico's national average. The United Nations AIDS Program considers an HIV epidemic to advance from a low level to a concentrated epidemic when more than 1% of the population is infected - a figure that Tijuana may soon approach if preventive steps aren't taken, as per researchers.........

Did you know?
Adolescents who suffer physical injuries are vulnerable to emotional distress in the months following their hospitalization, yet almost 40 percent of hospitalized adolescents interviewed for a new study had no source for the follow-up medical care that could diagnose and treat symptoms of post-traumatic stress. These young trauma survivors are at risk for high levels of post-traumatic stress and depressive symptoms, as well as high levels of alcohol use, according to research by researchers at the Harborview Injury Prevention and Research Center.
