A meta-analysis of previously published studies finds no evidence that statins are associated with a reduced risk of death among individuals at risk for but with no history of cardiovascular disease, according to a report in the June 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

A mathematical model suggests that aggressively pursuing low blood pressure and cholesterol levels may not benefit, and could even harm, some patients with diabetes, according to a report in the June 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Bicycling and brisk walking are associated with less weight gain among pre-menopausal women, especially those who are overweight and obese, according to a report in the June 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

A new study of nearly 8,800 women with early-stage breast cancer found that fewer than half – approximately 49 percent – completed their full regimen of hormone therapy according to the prescribed schedule. Investigators found that younger women were particularly likely to discontinue treatment. The findings underscore the need to both better understand the reasons behind such treatment non-compliance and also develop interventions to reduce it.

CHICAGO --- Women who measure their peak heart rates for exercise will need to do some new math as will physicians giving stress tests to patients.

A new formula based on a large study from Northwestern Medicine provides a more accurate estimate of the peak heart rate a healthy woman should attain during exercise. It also will more accurately predict the risk of heart-related death during a stress test.

DURHAM, N.C. -- The average man experiences hormone changes similar to the passive bonobo prior to competition, but a "status-striving" man undergoes changes that mirror those found in a chimpanzee, say researchers from Duke and Harvard universities.

A new study published Monday (today) in Proceedings of the National Academy of Sciences reveals differing hormone levels in our two closest relatives, bonobos and chimpanzees, in anticipation of competition.

Does competition decrease in ecologies where all struggle to survive?

Hurricanes, wildfires and influxes of pollutants create disturbances that can put ecological systems under extreme stress. Ecologists had believed that at times like these, competition between species becomes less important as all struggle to survive.

Gene leads to longer shelf life for tomatoes, possibly other fruits

Children with developmental coordination disorder are at greater risk of being overweight or obese according to a study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj091454.pdf.

TORONTO, June 28, 2010 − Protecting ourselves from backyard mosquito bites may come down to leaving the vacuuming for later, a study from York University shows.

Rather than vacuuming the grass clippings out of catch basins before adding treatments to control mosquitoes, municipalities should leave the organic waste in place, the research found.

Underwater sponges and worms may hold key to cure for malaria

Healing powers for one of the world's deadliest diseases may lie within sponges, sea worms and other underwater creatures.

WINSTON-SALEM, N.C. – Monday, June 28, 2010 – In the first ever published estimate of the percentage and number of cancer survivors who live with their minor children, a team led by a Wake Forest University Baptist Medical Center researcher found that millions of cancer survivors are parenting young children, highlighting a group of survivors with very special needs.

Published early online today in Cancer, a peer-reviewed journal of the American Cancer Society, the study's results may help address the unmet needs of this unique group of patients and their families.
