Recent stories on Highlight HEALTH

Have you ever heard a person in poor health being told “Well, you’ve got to stay positive, that will help”? This seemingly common idea is currently under significant scientific investigation. Indeed, the debate about the degree to which psychological processes can directly influence physical health has received special attention recently. A special supplement of the Annals of Behavioural Medicine directly addressed this topic in February this year and a recent article in the Lancet explored this issue, cautioning us that the relationship between a positive psychological orientation and cancer survival remains unclear [1].

Programs to create a new center for the study of stem cells and to increase capacity to deal with global health issues were among seven scientific initiatives announced today by NIH Director Francis S. Collins, M.D., Ph.D. The seven research programs are supported through the NIH Common Fund, which encourages collaborative research programs across the NIH institutes and centers, or ICs, to accomplish work that no single IC could do alone. The programs are all scheduled to begin during fiscal year 2010.
“These strategic investments will yield critical new resources, scientific knowledge, and strategic partnerships across a broad landscape of basic biology, behavioral science, global health, and clinical medicine,” said Dr. Collins.
The research programs will distribute $17.8 million in NIH Common Fund (http://commonfund.nih.gov) support in fiscal year 2010, and additional funds in future years. These projects capitalize on emerging scientific opportunities and technology advances to fuel biomedical discovery, strengthen the biomedical community nationally and globally, and hasten the translation of science discoveries into new and better treatments.

Statins are a class of drugs that lower cholesterol and thereby reduce the risk of heart disease and stroke. They work by preventing the synthesis of low-density lipoprotein (LDL or “bad cholesterol”) in the liver and promoting its clearance from the blood. They are the most effective cholesterol-lowering drugs currently available and are the cornerstone of the National Heart, Lung, and Blood Institute’s National Cholesterol Education Program (NCEP) treatment guidelines.
The NCEP recommends a “treat-to-target” strategy, in which patients are given specific statin doses to achieve a desired level of LDL cholesterol in the blood. In this case, low LDL cholesterol is the “target.” Yet some physicians are questioning whether treating to any target is the best approach to fighting disease. A recent study in the Annals of Internal Medicine suggests that “tailored treatment”, an approach attempts to practice personalized medicine by estimating three factors, is more effective than a treat-to-target strategy [1].

Scientists have devised a new computational model that can be used to reveal genetic regulatory elements responsible for development of the human heart and maintenance of its function.
Although the teams focused on the heart, the computational method they developed is broadly applicable to other tissues, and was successfully used to identify regulatory elements for cells of the limbs and brain. Cataloging these regulatory sequences may improve understanding of diseases and lays the groundwork for improved medical treatments.
The research, conducted by scientists at the National Institutes of Health’s National Center for Biotechnology Information (NCBI) and the University of Chicago, is published in the March 2010 issue of Genome Research and is available online.
