model that indicates that child care seems to affect pneumococcal carriage in individuals as well as in communities. Individually, the model predicts the risk of pneumococcal carriage is two to three times higher for a child who attends child care th...
Computational tool predicts how drugs work in cells, advancing efforts to design better medicines

formula of the MELD score. While serum sodium can be decreased with the use of diuretics and can therefore be manipulated, this disadvantage also applies to serum creatinine. The authors conclude that the study "shows that hyponatremia is an excellen...
Small increases or 'blips' in HIV levels do not signal mutations leading to drug-resistant HIV
...kins team has shown that these so-called blips are mathematical
artifacts, or variations, that stem from the test used to gauge the amount of virus in the body, a measurement known as viral load. According to the Hopkins findings, to be published in the Journal of the American Medical Association online Feb. 16...
Boosting HIV screening can increase survival and is cost effective
...nded screening." Paltiel and his team developed a mathematical
model of HIV screening and treatment to predict the costs and benefits of HIV counseling, testing and referral. They found that routine, voluntary HIV screening every three to five years is cost-effective by U.S. standards, in all but the lowest-risk...
