Reducing Gasoline Emissions Will Benefit Human Health
President Barack Obama and Energy Secretary Steve Chu are consistent in their message that when it comes to transportation fuels, carbon-neutral biofuels as an alternative to gasoline are coming. While the focus of a shift from gasoline to biofuels has been on global warming, such a shift could also impact human health. A grant from the Energy Biosciences Institute (EBI) has produced a novel and comprehensive "Life Cycle Impact Assessment" to measure the benefits on human health that might result from a switch to biofuels. Although there are a number of uncertainties that must be addressed for a more accurate picture, these early results show that a biofuel eliminating even 10-percent of current gasoline pollutant emissions would have a substantial impact on human health in this country, especially in urban areas.

Reduced Risk Of Stroke, Further Heart Attack And Death For Patients After A Heart Attack Or Unstable Angina With Oral Rivaroxaban
The findings of the ATLAS ACS-TIMI 46 study are reported in an article Online First and in a future edition of The Lancet, and written by Dr Jessica L Mega, Brigham and Women"s Hospital, Boston, MA, USA, and collaborators. They suggest that the intake of the oral anti-clotting drug rivaroxaban in patients after an acute coronary syndrome (such as a heart attack or an unstable angina) reduces the risk of stroke, another heart attack, and death.

Missouri Judge Approves Summary, Cost Estimate For Abortion Ballot Proposal
Missouri Judge Patricia Joyce last week dismissed conspiracy allegations against three state officials and approved the summary and cost estimate for a proposed constitutional amendment that would ban public funding for abortions and certain types of embryonic stem cell research, the AP/St. Louis Post-Dispatch reports.The Missouri Roundtable for Life proposed the ballot measure earlier this year. Supporters of the measure subsequently argued that a summary written by Missouri"s secretary of state was biased. At the same time, opponents of the measure argued that the original petition was improperly drafted and should not have been allowed to proceed.Joyce dismissed the challenges to the summary and cost estimate, which was prepared by the state auditor. She also rejected the Roundtable"s claims that three state officials -- Secretary of State Robin Carnahan, Attorney General Chris Koster and State Auditor Susan Montee -- conspired to violate sponsors" constitutional rights. Joyce ruled that the allegations "are without merit and rise to the level of being frivolous."Steve Clark, an attorney representing the Roundtable, said his clients have not yet decided whether they will appeal. If they appeal and the summary is changed, new signatures will be required to support the new language. Supporters hope to place the measure on the 2010 ballot (Blank, AP/St. Louis Post-Dispatch, 6/20).

New Study Indicates Radiologists Need Standards To Ensure Optimal Visual Accuracy

Radiologists, like professional pilots for example, depend on good vision as part of their occupation. However, radiologists unlike pilots are not required to undergo regular vision testing. A new study found that approximately 50% of radiologists surveyed indicated they don"t recall ever having their vision tested or it had been 24 months or longer since their last vision exam. The study, performed at the University of Maryland School of Medicine in Baltimore, MD, included 48 radiologists who opted to undergo a brief survey before undergoing visual acuity testing. "Of the 48 participating radiologists, eight could not recall ever having their vision examined," said Nabile Safdar, MD, lead author of the study. "Fourteen of the participants reported that their last eye examinations were 24 months or more in the past. One radiologist even indicated that it had been 15 years since his last eye examination," said Dr. Safdar. The visual acuity of the participants at any given measurement ranged from 20/30 to 20/10. "Physicians and patients depend on the ability of radiologists to accurately discriminate findings and render appropriate diagnoses based on these findings," he said. "Although the variation we found in visual acuity among radiologists is unlikely to have an influence on clinical diagnostic performance, as radiologists, we may have a responsibility to our patients and ourselves-to make sure our vision is as good as possible. In the future, professional guidelines should be considered to ensure optimal visual accuracy," said Dr. Safdar. This study appears in the June issue of the American Journal of Roentgenology.
