Mental Attitude: A Sense of Purpose Is Important for Heart Health.
A review
of past research involving more than 137,000 individuals found that living a
life with a strong sense of purpose may lower a person's risk of early death,
heart attack, and stroke. Compared with those lacking a sense of meaning and
direction in life, researchers found that study participants possessing a
strong sense of purpose had a 23% reduced risk of premature death from any
cause and a 19% lower risk for cardiovascular-related events such as heart
attack or stroke. Study author Dr. Randy Cohen writes, "Purpose in life is
considered a basic psychological need, and has been defined as a sense of
meaning and direction in one's life, which gives the feeling that life is worth
living."

Health Alert: Air Pollution May Increase Stroke Risk.
A new
study has discovered that high levels of small-particle air pollution can
increase an individual's risk for narrowing of the carotid arteries in the
neck, a risk factor for stroke. The findings come from screening tests of more
than 300,000 people living in New York. Investigators found that those who live
in areas with high levels of air pollution were 24% more likely to have
narrowing of the arteries that deliver blood to the brain. Lead author Dr.
Jonathan Newman adds, "If you're in good health, the level of air
pollution we see in most parts of the United States probably doesn't pose a
significant health risk to you. But for people who are very young, very old, or
have other medical problems, air pollution could be a significant source of
cardiovascular disease risk."

Diet: Lycopene May Reduce Risk of Kidney Cancer in Older Women.
Lycopene
is an antioxidant compound commonly advertised as a component of tomatoes and
tomato products. An analysis of data from over 96,000 postmenopausal women
revealed that a higher intake of lycopene is associated with up to a 39%
reduced risk for developing renal cell carcinoma.

Exercise: Can Interactive Cycling Games Provide an Alternative to
Conventional Exercise?
Scientists
recently compared the physiological and enjoyment responses between
conventional cycling and interactive video game cycling. They found that
interactive video game cycling was more enjoyable for study participants and
led to a higher overall energy expenditure. Based on these findings, the
researchers concluded that interactive cycling games could be a suitable
alternative to conventional exercise.

Chiropractic: Back Pain Prevalence and Obesity Around the World.
Using
data collected from 42,116 individuals from nine countries across five
continents, researchers have found that obesity can increase an individual's
risk for back pain 1.4 to 3.3 times when compared with their countrymen whose
body mass index scores fall in the normal range. While further studies are
needed to identify what factors lead to greater back pain risk for obese adults
in some countries, it's clear that maintaining a healthy weight should be an
important part of everyone's back pain prevention strategy.

Wellness/Prevention: This May Slow Cardiovascular Disease in Patients with Kidney
Disease.
For
kidney disease patients, cardiovascular disease is the main cause of morbidity
and mortality. An animal-based study looked at the effect of daily exercise on
mice with compromised kidney function. Compared with sedentary mice,
researchers observed considerably less aortic plaque build-up in the mice that
exercised. Further research is necessary to verify these findings and
eventually determine if such benefits translate to human kidney disease
patients.
