The purpose of this experiment was to determine whether Bluestar Forensic was capable of detecting latent bloodstains under multiple coats of paint. In order to test this, three different bloodstain patterns (handprint transfer, drip and hair swipe) were applied to three types of substrates (brick, f lakeboard, and dry wall). After each of the bloodstains had been applied to the substrates, the stains were systematically painted over multiple times with three separate colors and types of paint. After each coat of paint was applied and allowed to dry, Bluestar Forensic was then sprayed over the test areas to see whether a reaction occurred with the concealed bloodstain. Reactions were visualized, recorded and photographed. The findings of this study show that Bluestar Forensic was able to detect bloodstains through at least three to four layers of paint in most circumstances. However, results did vary and were dependent upon the type and color of paint used as well as the bloodstain pattern applied. [ABSTRACT FROM AUTHOR]

The article offers information on the updated position paper on the policies relating to HIV infection in the U.S. The position paper on HIV policy has been established in collaboration with the HIV Medicine Association of the Infectious Diseases Society of America and the American College of Physicians. The updated HIV policy highlights major advances on the treatment of HIV infection, the expansion of HIV as a pandemic and the prevalence of HIV transmission in health care settings.
