Researchers at Columbia University's Mailman School of Public Health have released findings identifying factors that affected evacuation from the World Trade Center (WTC) Towers on September 11. A research methodology known as participatory action research (PAR) was used to identify individual, organizational, and structural (environmental) barriers to safe and rapid evacuation. http://www.physorg.com/news152190377.html Medicine & Health Mon, 26 Jan 2009 11:06:43 EST news152190377 New research conducted at Columbia University Mailman School of Public Health indicates that the advertising of alcohol in predominantly African-American neighborhoods of New York City may add to problem drinking behavior among residents. Prior studies have shown that alcohol advertisements are disproportionately located in African- American neighborhoods, but the impact of such advertising on alcohol consumption has been unclear. The study is currently published online by the American Journal of Public Health. http://www.physorg.com/news150990650.html Medicine & Health Mon, 12 Jan 2009 13:50:50 EST news150990650 A study released by researchers at the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health shows that developing antibodies to cockroach and mouse proteins is associated with a greater risk for wheeze, hay fever, and eczema in preschool urban children as young as three years of age. The study, published in the November 2008 issue of the Journal of Allergy and Clinical Immunology, is the first to focus on the links between antibody responses to cockroach and mouse proteins and respiratory and allergic symptoms in such a young age group. http://www.physorg.com/news145814327.html Medicine & Health Thu, 13 Nov 2008 15:58:47 EST news145814327 A study initiated by researchers at Columbia University Mailman School of Public Health and the Leiden University Medical Center in the Netherlands suggests that prenatal exposure to famine can lead to epigenetic changes that may affect a person's health into midlife. The findings show a trickle-down effect from pregnant women to the DNA of their unborn children and the timeframe over which such early damage can operate. While previous studies have suggested that adult disease risk may be associated with adverse environmental conditions early in development, these data are the first to show that early-life environmental conditions can cause epigenetic changes in humans that persist throughout life. The full study findings are published online in the Proceedings of the National Academy of Science. http://www.physorg.com/news144598464.html Medicine & Health Thu, 30 Oct 2008 15:14:24 EST news144598464 Researchers from Columbia University Mailman School of Public Health and the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center, have found a strong association between women of African descent from the U.S. and Caribbean, who are otherwise healthy, and the prevalence of neutropenia, or low white blood count. Neutropenia, which is associated with race and ethnicity, has essentially been unexplained and, although thought to be benign, may affect therapy for cancer or other illnesses. Among women of African descent who develop a malignancy, this association may contribute to racial disparities in treatment and outcomes. The study findings are reported online in Blackwell Publishing Ltd. British Journal of Hematology (August 2008). http://www.physorg.com/news141052940.html Medicine & Health Fri, 19 Sep 2008 14:22:20 EST news141052940 In a case-control study, the presence of measles virus RNA was no more likely in children with autism and GI disturbances than in children with only GI disturbances. Furthermore, GI symptom and autism onset were unrelated to MMR vaccine timing. http://www.physorg.com/news139750699.html Medicine & Health Thu, 04 Sep 2008 12:38:19 EST news139750699 According to a study conducted at Columbia University Mailman School of Public Health, health risk behaviors such as smoking and obesity are associated with lower awareness of the Prostate Specific Antigen (PSA), which could lead to a lower likelihood of undergoing actual prostate cancer screening. Although previous studies have explored predictors of PSA test awareness, this is the first research to focus on health risk behaviors, such as smoking, physical inactivity, obesity, and excessive alcohol consumption. The study findings were reported in the August issue of The Journal of Urology. http://www.physorg.com/news139053457.html Medicine & Health Wed, 27 Aug 2008 10:57:37 EST news139053457 (PhysOrg.com) -- Periodontal disease may be an independent predictor of incident Type 2 diabetes, according to a study by researchers at Columbia University Mailman School of Public Health. While diabetes has long been believed to be a risk factor for periodontal infections, this is the first study exploring whether the reverse might also be true, that is, if periodontal infections can contribute to the development of diabetes. The full study findings are published in the July 2008 issue of Diabetes Care. http://www.physorg.com/news137682253.html Medicine & Health Mon, 11 Aug 2008 14:04:13 EST news137682253 Periodontal disease may be an independent predictor of incident Type 2 diabetes, according to a study by researchers at Columbia University Mailman School of Public Health.

In these settings, HIV-infected mothers had been advised that for the best outcome for their infants, they should exclusively breast-feed, followed by a rapid weaning four to six months after birth. http://www.physorg.com/news136123250.html Medicine & Health Thu, 24 Jul 2008 13:00:50 EST news136123250 Closing coal-fired power plants can have a direct, positive impact on children's cognitive development and health according to a study released by the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health. The study allowed researchers to track and compare the development of two groups of children born in Tongliang, a city in China's Chongqing Municipality - one in utero while a coal-fired power plant was operating in the city and one in utero after the Chinese government had closed the plant. Among the first group of children, prenatal exposure to coal-burning emissions was associated with significantly lower average developmental scores and reduced motor development at age two. In the second unexposed group, these adverse effects were no longer observed; and the frequency of delayed motor developmental was significantly reduced. The study findings are published in the July 14th Environmental Health Perspectives. http://www.physorg.com/news135268332.html Medicine & Health Mon, 14 Jul 2008 15:32:12 EST news135268332
