3D breast imaging could revolutionize cancer screening

Detection rate for invasive cancers significantly higher than 2D digital mammography

2014-06-18

(Press-News.org) Leesburg, VA, June 17, 2014—In community-based radiology practice, mammography screening with 3D digital breast tomosynthesis (DBT) yielded lower recall rates, an increased overall cancer detection rate, and an increased detection rate for invasive cancer compared with 2D digital mammography (DM).

In the largest report to date, researchers at Washington Radiology Associates, PC, with offices in Washington, DC; Virginia; and Maryland, conducted a study of more than 59,000 patients. The results were striking: an increase in the detection rate for cancer overall of 28.6% and a 43.8% increase in detecting invasive cancers in patients screened with 3D DBT versus 2D DM.

"We observed a significant increase in the detection rate for cancer overall and an even greater increase in the detection rate for invasive cancer," said Julianne Greenberg, corresponding author of the study. "Our results may be a bellwether for the impact of tomosynthesis on population-based breast cancer screening."

The study appears ahead of print online in the American Journal of Roentgenology.

Exposure to TV violence related to irregular attention and brain structure

2014-06-18

INDIANAPOLIS -- Young adult men who watched more violence on television showed indications of less mature brain development and poorer executive functioning, according to the results of an Indiana University School of Medicine study published online in the journal Brain and Cognition. The researchers used psychological testing and MRI scans to measure mental abilities and volume of brain regions in 65 healthy males with normal IQ between the age of 18 and 29, specifically chosen because they were not frequent video game players. Lead author Tom A. Hummer, Ph.D., assistant ...

Wildlife scientists map fishing resources to assist land managers, anglers

2014-06-18

Anglers in North Carolina and Virginia who are looking for privacy at good fishing spots should head for the mountains, according to a Virginia Tech study of the capacity, quality, and demand of freshwater recreational fishing sites in the two states. "Our objective was to map a cultural ecosystem service by identifying the key features that influence anglers' enjoyment, such as environmental quality, accessibility, and fish abundance," said Amy Villamagna, a research scientist with the College of Natural Resources and Environment's fish and wildlife conservation department. ...

New method to identify inks could help preserve historical documents

2014-06-18

The inks on historical documents can hold many secrets. Its ingredients can help trace trade routes and help understand a work's historical significance. And knowing how the ink breaks down can help cultural heritage scientists preserve valuable treasures. In a study published in the Journal of the American Chemical Society, researchers report the development of a new, non-destructive method that can identify many types of inks on various papers and other surfaces. Richard Van Duyne, Nilam Shah and colleagues explain that the challenge for analyzing inks on historical ...

Ban on pavement sealant lowered levels of potentially harmful compounds in lake

2014-06-18

In 2006, Austin, Texas, became the first city in the country to ban a commonly used pavement sealant over concerns that it was a major source of cancer-causing compounds in the environment. Eight years later, the city's action seems to have made a big dent in the targeted compounds' levels — researchers now report that the concentrations have dropped significantly. They published their study in the ACS journal Environmental Science & Technology. Peter C. Van Metre and Barbara J. Mahler point out that in 2005, researchers figured out that pavement sealants made from coal ...

Majority of minors engage in sexting, unaware of harsh legal consequences

2014-06-18

Sexting among youth is more prevalent than previously thought, according to a new study from Drexel University that was based on a survey of undergraduate students at a large northeastern university. More than 50 percent of those surveyed reported that they had exchanged sexually explicit text messages, with or without photographic images, as minors. The study also found that the majority of young people are not aware of the legal ramifications of underage sexting. In fact, most respondents were unaware that many jurisdictions consider sexting among minors – particularly ...

Litter-dwelling thrips live mainly in tropical and subtropical regions

2014-06-18

The species diversity in soil fauna has been studied in temperate regions for more than 50 years, but with scarcely any mention of thrips. This lack of reference to thrips raises the question whether or not litter-dwelling thrips are distributed only in tropical and sub-tropical regions. To answer this question a total 150 leaf litter samples were collected from 6 natural reserves located in three climatic regions, temperate, subtropical and tropical, along a 4100 km latitudinal gradient in East China. The survey was done over a four-year period by Dr Jun Wang, who is ...

Kids whose time is less structured are better able to meet their own goals

2014-06-18

Children who spend more time in less structured activities—from playing outside to reading books to visiting the zoo—are better able to set their own goals and take actions to meet those goals without prodding from adults, according to a new study by the University of Colorado Boulder. The study, published online in the journal Frontiers in Psychology, also found that children who participate in more structured activities—including soccer practice, piano lessons and homework—had poorer "self-directed executive function," a measure of the ability to set and reach goals ...

Dismisses link between suicidal behaviour and ADHD drugs

2014-06-18

A new register-based study from Karolinska Institutet in Sweden shows that drug therapy for ADHD does not entail an increased risk of suicide attempts or suicide, as was previously feared. The results are published in the British Medical Journal (BMJ). "Our work in several ways shows that most likely there is no link between treatment with ADHD drugs and an increased risk of suicide attempts or suicide. The results rather indicate that ADHD drugs may have a protective effect," says Henrik Larsson, researcher at the Department of Medical Epidemiology and Biostatistics, ...

New horned dinosaur reveals unique wing-shaped headgear

2014-06-18

Cleveland, Ohio - Scientists have named a new species of horned dinosaur (ceratopsian) based on fossils collected from Montana in the United States and Alberta, Canada. Mercuriceratops (mer-cure-E-sare-ah-tops) gemini was approximately 6 meters (20 feet) long and weighed more than 2 tons. It lived about 77 million years ago during the Late Cretaceous Period. Research describing the new species is published online in the journal Naturwissenschaften. Mercuriceratops (Mercuri + ceratops) means "Mercury horned-face," referring to the wing-like ornamentation on its head ...

Spanish slug -- Busting an invasion myth

2014-06-18

Frankfurt am Main, Germany, June 18th 2014. Spanish slugs (Arion lusitanicus) are one of the most common slug species in Central Europe. The animals sometimes nicknamed "killer slugs" are known to do their fair share of damage in fields and gardens. The slug was thought to have originated in Southern Europe. However researchers of the German Biodiversity and Climate Centre and the Goethe University now found out, that the prime example of an invasive species is originally from Central Europe and thus no "immigrant" after all. Control measures, such as the EU regulation ...
