Children of Smokers Suffer Negative Health Effects Later in Life
The negative effects of environmental tobacco smoke on a
child who lives with parents who smoke continue to linger long
after that child has left home, a new study suggests. In tests,
college students who were exposed to high levels of environmental
tobacco smoke (ETS) as children maintained higher blood pressure,
mean arterial pressure, and heart rate at rest and during
psychological stress compared to students who grew up with low
levels of ETS. (From a recent issue of the International Journal
of Behavioral Medicine.)

Most Home-Based Workers Are Male, Have Traditional Jobs
Most home-based workers don’t fit the popular image of a
woman who provides child care or who sells crafts out of her
house, new research suggests. In fact, a study of 899 home-based
workers in nine states found that nearly 59 percent were male.
The average home-based worker was 44 years old, married, had some
education beyond high school and had been involved in work at
home for nearly a decade. “We found that most home-based workers
are men performing traditional work in fields like sales and
construction,” said a researcher here. (From a recent issue of
the journal Economic Development Quarterly.)

People Stay in City for Diversity, Move to Suburbs for Schools
Urban residents who move from a central city to the suburbs
are different in several noticeable ways from those who choose to
move within the city limits, a new study shows. Researchers at
Ohio State found that people who moved to the suburbs were more
likely to be concerned about school-related issues such as safety
and academic programs. In contrast, those who found new homes
within the city were more concerned about the cost of a new home,
staying near family and friends and neighborhood racial
diversity. (From a presentation March 26 in Honolulu, HI at the
annual meeting of the Association of American Geographers.)

Can Support for Democracy Be Taught? Study Shows Mixed Results
A new study suggests it may be difficult to teach teenagers
in post-communist societies to develop strong support for
democratic and free market principles. Researchers at Ohio State
found that 14- and 15-year-old Polish students who took a new
type of civics education class were less likely to take extreme
positions against democracy and the free market than were other
youth. But, unexpectedly, the study found that students taking
the new class were also less likely than were others to show a
strong commitment to democratic or market values. (From a recent
issue of the journal Political Psychology.)

Lo-Cal Diet Slows Prostate Cancer in Animals, New Research Finds
A low-calorie diet slows the progress of prostate cancer in
animals, new research shows. The slowing of tumor progression
occurred whether the calories were reduced by cutting fat,
carbohydrates, or the overall diet. The results further
suggested the way that the lower-calorie diet slowed tumor growth
in rats and mice -- it retarded the development of new blood
vessels in the tumor. “Our findings provide further evidence
that prostate-cancer development might be influenced by
lifestyle,” said a researcher here. (From the March 15 issue of
the Journal of the National Cancer Institute.)

Mechanism for Fungal Adherence Found, Possible Key to Disease
Researchers have discovered that a protein manufactured by
the fungus Candida albicans mimics the actions of a specific
mammalian protein, perhaps improving the organism’s chances to
flourish in immune-compromised patients. Researchers reported
that the fungi’s ability to adhere to cells lining the mucosal
surfaces of the mouth depends on the presence of this protein.
If the protein is missing, Candida simply cannot hang on. Among
the serious infections patients acquire while in the hospital --
so-called nosocomial infections -- Candida ranks among the top
five pathogens and is potentially fatal. (From the March 5 issue
of the journal Science.)

Women Smoking Menthol Cigarettes Have Greater Nicotine Exposure
Women who smoke menthol cigarettes may be more likely to
inhale deeper with each drag on their cigarette and potentially
take in more nicotine than do smokers of non-menthol cigarettes,
new research shows. The study also showed that users of menthol
cigarettes tend to smoke their first cigarette of the day sooner
than do users of non-menthol cigarettes. The sooner a person
smokes his or her first cigarette of the day, the more nicotine
dependent the person is thought to be. “These results should
caution smokers who believe that menthol cigarettes are in some
way healthier or less irritating than non-menthol brands,” said a
researcher here. (From a recent issue of the journal Addictive
Behaviors.)

Autoimmune Diseases Study Shows Differences Between Men And Women
A national task force of basic researchers and clinicians
spent 18 months assessing what is known about autoimmune diseases
and has now proposed an aggressive research agenda aimed at
understanding why men and women respond differently to these
illnesses. Their report recommends five distinct research areas
which may explain these differences and perhaps even offer new
treatments against the diseases. Nearly 79 percent of the 8.5
million autoimmune disease patients in the country are women.

Genetic Mutations Linked to Rare Metabolic Disease
Researchers have identified two mutations in a single gene
as the cause of a very rare metabolic disease that affects people
in Finland, Norway and Saudi Arabia. It has taken nearly 40
years since the identification of the disease for researchers to
trace its cause back to a faulty gene. Called megaloblastic
anemia 1, or Imerslund-Grasbeck syndrome, the defects prevent the
normal absorption of vitamin B-12. If left untreated, the
disease can be fatal. For this study, scientists mapped the DNA
of 17 Finnish patients who had the disease, comparing it to
disease-free control subjects. They also looked at DNA samples
from patients in Norway, as well as members of a Bedouin family
in Saudi Arabia, all of whom had the disease. (From the current
issue of the journal Nature Genetics.)
