Harvard researcher Andrea Baccarelli, MD, PhD, and colleagues in Italy studied 870 people diagnosed with DVT from 1995 to 2005. They compared their particulate air pollution exposure in the year before their diagnosis to that of 1,210 matched people without DVT.
They found that DVT risk goes up 70% for every 10 microgram-per-cubic-meterrise in particulate air pollution above 12 micrograms per cubic meter of air (the lowest pollution level measured in the study).
The U.S. EPA standard for particulate air pollution is 150 micrograms per cubic meter of air. However, it's likely that fine and very fine particles cause most of the health risks linked to particulate air pollution.
The simple truth, experts say, is that pounds must also be shed to keep cardiovascular trouble away.
"There is a debate out there about whether this generation is going to live as long as their parents, and the truth is they probably won't," said study author Dr. Gregory L. Burke, director of the division of public health sciences at Wake Forest University School of medicine in Winston-Salem, NC.
"My ultimate worry is that we've seen a 50-year decline in cardiovascular disease mortality, but if you begin to look at recent trends, it's beginning to plateau," he added. "And my fear is that because of the increase in obesity we're going to begin to see a reversal of that trend where heart disease rates begin to go up."
On Saturday, a tornado with the second-strongest rating killed six people, destroyed a 20-block area, and blew dust off mountains of mining waste, or chat piles.
"You can look at the chat piles and see that a lot of the material has blown off," said John Sparkman, head of the Picher housing authority. "We went up on a chat pile an hour and a half after the tornado hit, and you could see dust blowing fine material all over the place from that vantage point."
Long-term exposure to lead dust poses a health risk, particularly to young children.
The two conditions appear to increase one's risk for retinal vein occlusion, a condition that leads to vision loss. It results from one or more veins carrying blood from the eye to the heart becoming blocked and causing bleeding or fluid build-up, according to background information in the report published in the May issue of the Archives of Ophthalmology.
The Irish study found that people with high blood pressure had more than 3.5 times the risk of developing retinal vein occlusion than those without it. People with high cholesterol levels had an approximately 2.5-fold higher risk of retinal vein occlusion.
The findings come from an analysis of 21 previously published studies involving 2,916 people with retinal vein occlusion and 28,646 people without the condition. It found that 63.6 percent of patients with retinal vein occlusion also had hypertension, compared with 36.2 percent of people without the eye condition. High cholesterol levels were more than twice as likely to be found in those with retinal vein occlusion as those without (35.1 percent vs. 16.7 percent).
Fairbank Farms is issuing a voluntary recall of selected ground beef products produced at its Ashville, N.Y., facility and sold through Price Chopper, Shaw's, BJ's, and Wilson Farms retail outlets and C&S Wholesale distributor.
The affected product may contain small pieces of hard plastic. All recalled products have either a "sell-by" date of 05/13/08, 05/15/08, or a "Julian date 124" on the package's label.
New research shows "alarming levels" of obesity in most ethnic groups in the United States, principal investigator Dr. Gregory L. Burke, of Wake Forest University, Winston-Salem, North Carolina told Reuters Health. The study also confirms the potentially deadly toll obesity exacts on the heart and blood vessels.
"The obesity epidemic has the potential to reduce further gains in U.S. life expectancy, largely through an effect on cardiovascular disease mortality (death)," Burke and colleagues warn in the latest issue of Archives of Internal Medicine.
Among 6,814 middle-age or older adults participating in the Multi-Ethnic Study of Atherosclerosis, or "MESA" study, researchers found that more than two thirds of white, African American and Hispanic participants were overweight and one third to one half were obese.
The question is loaded and points to a really interesting diagnosis: What IS the biggest environmental problem on the planet? The answer is subjective, of course. If you are talking about global warming then coal plants are the biggest problem on the planet. If you are talking about natural resource preservation then deforestation is the biggest problem. Insert water for life sustainability and disease, or plastics for waste. To be sure, cigarettes are no one’s friend: Neither health nor the environment. In fact, in terms of litter, they are the biggest source of it: More than two billion pounds of cigarette butts are discarded worldwide – more than two pounds for every person in China. I use that country as an example because as I traveled from Beijing southward along the Silk Route, people still smoked a lot – everywhere. In Southeast Asia too people light up.
Smokers’ waste is rather easy to calculate. Figure out how many cigarettes are smoked and you’ll find out how many butts are tossed. You can’t recycle ‘em. One thing I’d like to know is the emission factor, or pollution due to smoking.
The experiments were conducted with the brain cells of rats and they show that contact with this ingredient called methylisothiazoline, or MIT, causes neurological damage.
Which products contain this chemical compound MIT? Head and Shoulders, Suave, Clairol and Pantene Hair Conditioner all contain this ingredient. Researchers are concerned that exposure to this chemical by pregnant women could put their fetus at risk for abnormal brain development. In other people, exposure could also be a factor in the development of Alzheimer's disease and other nervous system disorders.
The chemical causes these effects by preventing communication between neurons. Essentially, it slows the networking of neurons, and since the nervous system and brain function on a system of neural networks, the slowing of this network will suppress and impair the normal function of the brain and nervous system.
