Microbial RNA Ocean Catch Surprises MIT
An ingenious new method of obtaining marine microbe samples while preserving the microbes" natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs - snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence in a natural setting may make it possible finally to learn on a broad scale how microbial communities living at different ocean depths and regions respond to environmental stimuli.

The Publics' Ignorance Of Anatomy Revealed By Study

ISMP Launches First Self Assessment Of Automated Dispensing Cabinet Safety
More than 80% of hospitals across the U.S. have implemented automated dispensing cabinets (ADCs) as an important part of their drug distribution system, making the evaluation of practices and policies surrounding this technology an essential step in ensuring patient safety. To help meet healthcare organizations" growing need for assistance in this area, the Institute for Safe Medication Practices (ISMP) has introduced the first Medication Safety Self Assessment® for Automated Dispensing Cabinets.

Study Finds Association Between Sudden Death And Stimulant Medications Among Children And Adolescents

Researchers found support for an association between the use of stimulants and sudden unexplained death among children and adolescents, according to a study released today by The American Journal of Psychiatry. The rate of stimulant use among 564 children and adolescents whose sudden deaths were attributed to cardiac dysrhythmia or unknown causes was 1.8 percent, compared to 0.4 percent for youth who died as passengers in motor vehicle accidents. Although stimulant use had a greater association with sudden unexplained death, the overall incidence of sudden explained death was still rare. For some time, concerns have arisen that stimulants may increase the risk for sudden unexplained death in children. "Sudden Death and Use of Stimulant Medications in Youth" by Madelyn S. Gould, Ph.D., M.P.H. and colleagues is the first study to rigorously address concerns that the therapeutic use of stimulants, like amphetamine and dextroamphetamine, may increase the risk for sudden unexplained death in children. Most, but not all, of the stimulant use was prescribed for attention deficit hyperactivity disorder (ADHD). In an accompanying editorial, Benedetto Vitiello, M.D., and Kenneth Towbin, M.D., of the National Institute of Mental Health state that the findings of the study "should underscore that stimulants are not innocuous and that their therapeutic use requires careful diagnostic assessment, diligent safety screening, and ongoing monitoring. However, it is equally clear that sudden unexplained death is a rare event, this is only the first such study, it relies on small numbers, and it is not possible to quantify the risk beyond estimating that it is very small." Both the study and editorial were published online at AJP in Advance, the online advance edition of The American Journal of Psychiatry, the official journal of the American Psychiatric Association. This study was supported in part by a contract from the Food and Drug Administration and a grant from the National Institute of Mental Health. Other funding received by the individual authors is disclosed in the article itself. The American Journal of Psychiatry is the oldest continuously published medical specialty journal in the United States and was recently named one of the "Most Influential Journals in Biology & Medicine of the Last 100 Years."
