Domestic violence associated with chronic malnutrition in women and children in India
Boston, MA-- In a new, large-scale study exploring the link between domestic violence and chronic malnutrition, researchers from the Harvard School of Public Health (HSPH) have found that Indian mothers and children experiencing multiple incidents of domestic violence in the previous year are more likely to be anemic and underweight. The findings were published online March 26, 2008 in The American Journal of Epidemiology and will appear in an upcoming print issue of the journal.

How exercise changes structure and function of heart
For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed. Their study appears in the April Journal of Applied Physiology.

An apple a day does keep the doctor away
Washington, April 9 - There is, it appears, more than an element of truth in the old adage about an apple a day keeping the doctor away. A new study has found that eating an apple a day - or drinking its juice - is a sound way of maintaining a slimmer waistline and insuring oneself against high BP and cardiac disease.

Vaccine/antibody therapy effective, milder side effects in melanoma and ovarian cancer
BOSTON--One of the shortcomings of a therapy that uses millions of identical antibodies to boost the immune system's attack on cancer cells is that many patients whose tumors recede in response to the treatment also experience serious inflammatory problems, such as severe diarrhea and rashes. In a new study, a team led by Dana-Farber Cancer Institute researchers shows that giving periodic infusions of such monoclonal antibodies to patients who have received a widely used cancer vaccine unleashes a strong immune response to tumors, with less-harsh side effects.

XDR TB in South Africa traced to lack of drug susceptibility testing
In South Africa, the 2001 implementation of the World Health Organization�s anti-tuberculosis program may have inadvertently helped to create a new strain of extensively drug-resistant tuberculosis (XDR TB). In a new study published in the December 1 issue of Clinical Infectious Diseases, currently available online, researchers tracked the developing drug resistance of one particular strain of Mycobacterium tuberculosis over 12 years. They found that at the time of the 2001 adoption of the DOT+ strategy for multi-drug resistant strains, the strain was already resistant to one or more of the drugs mandated by that strategy, thus allowing the strain to survive and develop resistance to additional drugs.

Folic acid lowers blood arsenic levels, according to Mailman School of Public Health study
October 8, 2007 -- 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, naturally present in some aquifers used for drinking, is currently a significant public health problem in at least 70 countries, including several developing countries and also parts of the U.S. Chronic arsenic exposure is associated with increased risk for skin, liver and bladder cancers, skin lesions, cardiovascular disease, and other adverse health outcomes.

Now the researchers describe how a regulatory protein called CTLA-4 inhibits the action of HIV-specific CD4 T cells that control the overall response against the virus. The report will appear in the journal Nature Immunology and is receiving early online release.

Further studies will focus on better defining the magnitude and the sources of the variability. The intent is to better understand how glycemic index relates to chronic disease risk in a wide range of individuals.
