Louisiana health officials are warning residents not to use nonsterilized tap water in neti pots after the deaths of two people who exposed their brains to a deadly amoeba while flushing out their nasal passages.
The amoeba, Naegleria fowleri, can be found in lakes and ponds as well as in contaminated lukewarm tap water. The organism doesn't pose a threat when ingested, but if it becomes lodged in a person's nose it can end up in the brain and cause an infection.
The infection, lethal in 95% of cases, triggers an array of symptoms that resemble those of bacterial meningitis, including vomiting, headaches and sleepiness. As it progresses, it can cause changes in a person’s behavior and lead to confusion and hallucinations. It usually causes death within one to 12 days, according to the Centers for Disease Control and Prevention. FULL POST

Eighty-eight percent of U.S. children and adults consume more sodium per day than the amount recommended by federal dietary guidelines, according to a new report released today by the Centers for Disease Control and Prevention.
And most Americans aren't just exceeding these guidelines; they're shattering them. The U.S. Department of Health and Human Services and the U.S. Department of Agriculture recommend that adults and teens limit their daily sodium intake to 2,300 milligrams, but according to the report the average intake is 3,513 milligrams - 53% above the suggested limit.
The picture is even worse among the subpopulations for whom the daily recommended limit is 1,500 milligrams: people over 50; blacks; and those with high blood pressure, diabetes, or kidney disease. Members of these groups, which account for nearly half of the U.S. population, tend to be especially sensitive to sodium, yet 99% of them exceed the recommended intake and the average person more than doubles the 1,500-milligram limit.

Nearly one in 10 children in the U.S. has been diagnosed with attention deficit hyperactivity disorder (ADHD), and the rate appears to be growing, according to a report released Wednesday by the Centers for Disease Control and Prevention (CDC).
The percentage of children ages 4 to 17 who have ever been diagnosed with ADHD rose from 7.8 percent to 9.5 percent between 2003 and 2007—a 22 percent increase, the CDC found. The report was based on the results of the National Survey of Children's Health, a nationwide telephone survey of parents.

Women who stick to the Jenny Craig weight-loss program lose between three and four times as much weight as women who diet on their own, according to a new study published Saturday in the Journal of the American Medical Association.
The study was funded by the Jenny Craig company, which provides counseling services and prepackaged low-fat foods to dieters through a nationwide chain of retail centers, or via phone and mail.
Women who ate the prepared foods and checked in weekly with a trained Jenny Craig weight-loss counselor in person or by phone lost about 20 pounds after one year, on average.

More than one in five adults in the U.S. have arthritis or other joint-damaging conditions, and the ongoing obesity epidemic may be partly to blame, according to a report issued Thursday by the Centers for Disease Control and Prevention (CDC).
Roughly 50 million U.S. adults have some form of arthritis, the report estimates. That number includes people with osteoarthritis, which is typically caused by aging, as well as those with other, less common conditions such as rheumatoid arthritis, gout, lupus, and fibromyalgia.
