Scientists' Three Simple Rules

1 How to Avoid Scalding-Hot Coffee Burns

Noting the number of people burned or scalded by hot coffee which spills as they walk with it, fluid scientists at the University of California at Santa Barbara, led by mechanical engineer Rouslan Krechetnikov, studied the dynamics involved and found that people naturally accelerate while carrying coffee and usually spill it between their seventh and tenth steps. Spills are particularly likely when the carrier is looking ahead and not at the coffee. The researchers' recommendations: Maintain a slower and steadier pace; keep your eyes on your cup while walking; and the distance between the surface of the coffee and the cup's rim should equal at least one-eighth of the cup's diameter. Their report doesn’t mention it, but sticking to decaf might also help avoid sloshing.

Unrecognized Health Crisis

2 CDC Says Boomers Should Be Tested for Hep C

The Centers for Disease Control recommends that baby boomers, those born 1945-1965, be tested for hepatitis C, saying that this could save 120,000+ lives. "The CDC views hepatitis C as an unrecognized health crisis for the country and we believe the time is now for a bold response," says Dr. John W. Ward, CDC. The CDC’s push for wider testing is due in part to a 50% increase in the number of Americans dying from hepatitis C-related diseases. In addition, two new drugs were introduced in the past year that show promise in curing many cases that were previously thought incurable. Each year there are about 17000 new infections of the disease which is commonly spread through sharing needles used to inject drugs. The new recommendation is due to become final later in the year.

60 Percent Obese Teens at Risk

3 Half of Overweight Teens Face Heart Risk

Half of the overweight teenagers and 60 percent of obese teenagers in the U.S. have at least one risk factor for future heart disease, including high cholesterol, blood sugar or blood pressure levels, says the CDC. The findings, published today in Pediatrics, reveal that the percentage of adolescents diagnosed with pre-diabetes or diabetes rose from 9 to 21 percent, but other risk factors for heart disease were steady. The ongoing study involves 3,382 adolescents ages 12 to 19. Researchers say that people can keep their heart risk low if they reach age 45 to 50 with normal blood pressure, weight and cholesterol, and no diabetes.

Reduce Risk Breast Cancer

4 Moderate Weight Loss Lowers Sex Hormones

Overweight or obese postmenopausal women who aren't taking hormone-replacement therapy may be able to reduce their risk for common, estrogen-sensitive breast cancers by 25 to 50 percent if they lose 5 percent or more of their body weight, suggest researchers. Experts think that a relationship between body fat and estrogen production contributes to the risk of postmenopausal breast cancer. Women who received dietary weight loss intervention had significant reductions in hormone levels, but women who dieted and exercised had the best reduction in hormone levels. This is the first randomized, controlled clinical trial to examine the effects of weight loss on sex hormones in overweight or obese postmenopausal women. The findings are published in Journal of Clinical Oncology.

Hormones Hell on the Gut

5 The Pill and HRT Tied to GI Diseases

Results from two studies found that younger women on the pill tripled their risk of Crohn’s disease and post-menopausal women taking hormone replacement therapy were 1.7 times more likely to develop ulcerative colitis. Crohn’s disease results when the lining of the small and/or large intestines becomes inflamed to the point of bleeding. Ulcerative colitis is inflammation of the colon or rectum can lead to diarrhea, abdominal cramps and bleeding of the rectum. Researchers stressed that these studies did not show a cause-and-effect relationship, but the strong association of Crohn’s and the pill do concern them, especially in young women with a family history of the disease. Previous animal studies have demonstrated that estrogen makes the colon more susceptible to inflammation.
