CRESPAR: Report #3

The Center for Research on the Education of Students Placed at Risk (CRESPAR) was established in 1994 and continued until 2004. It was a collaboration between Johns Hopkins University and Howard University. CRESPAR’s mission was to conduct research, development, evaluation, and dissemination of replicable strategies designed to transform schooling for students who were placed at risk due to inadequate institutional responses to such factors as poverty, ethnic minority status, and non-English-speaking home background.The Talent Development approach to helping greater numbers of students succeed in middle school is based on a belief that all students can learn challenging material if the right types of support are given. The approach draws upon insights from recent research on alternatives to tracking, on the components of effective middle schools, and on clear theories of how to foster the positive relationships and supportive conditions that are so important to middle school adolescents, especially those adolescents placed at risk. This report presents the essential components of the Talent Development framework and describes their initial implementation in Evans Junior High School in Washington, DC and in Central East Middle School in Philadelphia.Office of Educational Research and Improvement, U.

Anti-inflammatory effects of propofol during cardiopulmonary bypass: a pilot study

INTRODUCTION: Propofol has been suggested as a useful adjunct to cardiopulmonary bypass (CPB) because of its potential protective effect on the heart mediated by a decrease in ischemia-reperfusion injury and inflammation at clinically relevant concentrations. In view of these potentially protective properties, which modulate many of the deleterious mechanism of inflammation attributable to reperfusion injury and CPB, we sought to determine whether starting a low dose of propofol infusion at the beginning of CPB would decrease inflammation as measured by pro-inflammatory markers. MATERIALS AND METHODS: We enrolled 24 patients undergoing elective coronary artery bypass graft (CABG). The study group received propofol at rate of 120 mcg/kg/min immediately after starting CPB and was maintained throughout the surgery and for the following 6 hours in the intensive care unit (ICU). The control group received propofol dose of 30-50 mcg/kg/min which was started at the time of chest closure with wires and continued for the next 6 hours in the ICU. Interleukins (IL) -6, -8 and -10 and tumor necrosis factor alpha (TNFalpha) were assayed. RESULT: The most significant difference was in the level of IL-6 which had a P value of less than 0.06. Starting a low dose propofol early during the CPB was not associated with significant hemodynamic instability in comparison with the control group. CONCLUSION: Our study shows that propofol may be suitable as an anti-inflammatory adjunct for patients undergoing CABG

Genetic and Environmental Contributions to Racial Disparities in Preterm Birth

The preterm birth rate exceeds 12% in the United States, and preterm birth continues to be a clinical and public health challenge globally. Even though preterm birth is a major contributor to infant mortality and lifelong morbidity, there are few effective strategies to predict preterm birth and few clinical interventions to prevent it. Genomic research approaches that identify risk factors at the intersection of genetics and the environment will likely provide insights. Both genetic and environmental factors are known to contribute to the racial disparity seen in preterm birth. Through the identification of relevant gene-environment interactions that contribute to preterm birth and may underlie the racial disparity in preterm birth, research that will translate to clinical practice and ultimately prevent a number of preterm births is possible.
