- Folic acid lowers blood arsenic levels, according to Mailman School of Public Health study
10-08-2007 · EurekAlert!
A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water. This toxic element is currently a significant public health problem in at least 70 countries. Chronic arsenic exposure is associated with increased risk for skin, liver and bladder cancers, skin lesions, cardiovascular disease, and other adverse health outcomes.

- Personal chaos in HIV patients' lives may be a barrier to regular medical care, UCLA Study Shows
09-11-2007 · EurekAlert!
Unstable and unpredictable lifestyles are significant factors in determining access to health care among low-income, HIV-positive people, a new UCLA study has found. The study found that when HIV patients lead chaotic lives -- meaning they are disorganized or experience too many unexpected events -- that chaos can act as a barrier to regular medical care. The researchers also developed a new scale to gauge the level of chaos in an adult's life.

In a new survey of noise levels of the New York City transit system, researchers at Columbia University's Mailman School of Public Health found that exposure to noise levels in subways have the potential to exceed recommended guidelines of the World Health Organization (WHO) and the US Environmental Protection Agency (EPA). According to the research, as little as 30 minutes of exposure to decibel levels measured in the New York City transit system per day has the potential to result in hearing loss.
