Two federal agencies say they will cooperate closely to speed up work on experimental drugs. The US Food and Drugs Administration and the National Institutes of Health are in on the venture, which will have the NIH redesigning some basic research. That can move drugs more quickly through the FDA approval process. Health and Human Services Secretary Kathleen Sebelius said collaboration will 'go a long way towards fostering access to the safest most effective therapies for the American people.'

Researchers have found a link between low serotonin levels and sudden infant deaths. Researchers from Harvard Medical School and Children's Hospital Boston examined brain tissue from babies who died of SIDS than those who died from other causes. The team found that serotonin levels were 26 percent lower in babies who died of SIDS than those who died from other causes.
The researchers hope the study will lead to a test to identify children at highest risk for SIDS. The findings are published in the "Journal of the American Medical Association."

Millions of asthma sufferers take the drugs because they contain chemicals called LABAs that relax the muscles around stressed airways. The FDA cites studies linking lABA medications to an increased risk of hospitalization and death, especially among children. The agency is urging doctors to switch patients off Advair, Symbicort, Foradil and Serevent and onto traditional corticosteroid inhalers whenever possible.

Aspirin may help prevent the recurrence of breast cancer. A study of more than 4,000 nurses has found those who took a low dose aspirin on a regular basis, had a 50% lower risk of the cancer returning. Researchers at the Harvard Medical School say if their findings are confirmed in other clinical trials, taking a simple aspirin could become a simple, low-cost and fairly safe tool to help women with breast cancer live longer, healthier lives.
