Researchers Discover Key To Malaria Susceptibility In Children
A team of researchers from Case Western Reserve University School of Medicine have solved the mystery of why some children are more susceptible to malaria infection and anemia. These novel findings suggest that some children who are exposed to Plasmodium falciparum (P. falciparum) malaria before birth become tolerant to the malaria parasites, or their soluble products. This tolerance, which persists into childhood, reduces the ability of the immune system to attack and destroy parasites and increases the susceptibility of these children to develop a malaria infection. It also increases their risk for anemia. The study, published in this week"s issue of the open access journal, PLoS Medicine, is led by Indu Malhotra, Ph.D., and Christopher King, M.D., Ph.D., professor of international health, medicine, and pathology, with their colleagues at the Center for Global Health and Diseases at the Case Western Reserve University School of Medicine and their Kenyan colleagues at the Kenya Medical Research Institute and Division of Vector Borne Diseases.

Cholesterol Lowering Drugs May Help Prevent Stroke Recurrence
People who take cholesterol-lowering drugs called statins after a stroke may be less likely to have another stroke later, according to research published in the May 26, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Preventing Road Rage, UK
Figures from the British Institute for Anger Management reveal that the UK already has the worst road rage figures of any European nation, with 80% of drivers saying they"ve been involved in an incident and 1 in 4 admitting to committing an act of road rage themselves. Men are three times more likely to commit an act of aggression than women and over 60% of drivers say they have been intimidated by aggressive tailgating.

A Mother's Exposure To Urban Air Pollutants Can Affect Her Baby's IQ

Prenatal exposure to environmental pollutants known as polycyclic aromatic hydrocarbons (PAHs) can adversely affect a child"s intelligence quotient or IQ, according to new research by the the Columbia Center for Children"s Environmental Health (CCCEH) at the Mailman School of Public Health. PAHs are chemicals released into the air from the burning of coal, diesel, oil and gas, or other organic substances such as tobacco. In urban areas motor vehicles are a major of PAHs. The study findings are published in the August 2009 issue of Pediatrics. The study, funded by the National Institute of Environmental Health Sciences (NIEHS), a component of the National Institutes of Health, the U.S. Environmental Protection Agency and several private foundations, found that children exposed to high levels of PAHs in New York City had full scale and verbal IQ scores that were 4.31 and 4.67 points lower, respectively than those of less exposed children. High PAH levels were defined as above the median of 2.26 nanograms per cubic meter (ng/m3). "These findings are of concern because these decreases in IQ could be educationally meaningful in terms of school performance," says Frederica Perera, DrPH, professor of Environmental Health Sciences and director of the CCCEH at Columbia University Mailman School of Public Health and study lead author. "The good news is that we have seen a decline in air pollution exposure in our cohort since 1998, testifying to the importance of policies to reduce traffic congestion and other s of fossil fuel combustion byproducts." The study included children who were born to non-smoking Black and Dominican American women age 18 to 35 who resided in Washington Heights, Harlem or the South Bronx in New York. The children were followed from in utero to 5 years of age. The mothers wore personal air monitors during pregnancy to measure exposure to PAHs and they responded to questionnaires. At 5 years of age, 249 children were given an intelligence test known as the Wechsler Preschool and Primary Scale of the Intelligence, which provides verbal, performance and full-scale IQ scores. The researchers developed models to calculate the associations between prenatal PAH exposure and IQ. They accounted for other factors such as second-hand smoke exposure, lead, mother"s education and the quality of the home caretaking environment. Study participants exposed to air pollution levels below the average were designated as having "low exposure," while those exposed to pollution levels above the average were identified as "high exposure." A total of 140 children were classified as having high PAH exposure. "The decrease in full-scale IQ score among the more exposed children is similar to that seen with low-level lead exposure," noted Dr. Perera. "This finding is of concern because IQ is an important predictor of future academic performance, and PAHs are widespread in urban environments and throughout the world. Fortunately, airborne PAH concentrations can be reduced through currently available controls, alternative energy s and policy interventions." Mailman School of Public Health"s Li Zhigang, Robin Whyatt, Lori Hoepner, Shuang Wang, David Camann, and Virginia Rauh were co-authors of the study.
