3-D breast imaging could revolutionize cancer screening

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

2014-06-17

(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.

Hyperthyroidism patients more likely to take extended sick leave than healthy peers

2014-06-17

Washington, DC—People who have hyperthyroidism are more likely to take sick leave for extended periods than their healthy colleagues, particularly in the first year after diagnosis, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Hyperthyroidism occurs when the thyroid gland is overactive. The thyroid, which is located in the front of the neck, secretes hormones that regulate how the body uses energy, consumes oxygen and produces heat. The most common cause of hyperthyroidism is Graves' disease, ...

Pitt psychology researchers explore how engineers create

2014-06-17

PITTSBURGH—Simply put, engineers make things. But is finding that "new" invention a massive mental leap from point A to point B, or are there scores of unnoticed intermediate steps in between? The University of Pittsburgh's Joel Chan and Christian Schunn say that not enough has been done to understand how engineers create. Understanding the process, they say, may provide a road map for speeding up innovation. Chan, a graduate student in psychology in Pitt's Kenneth P. Dietrich School of Arts and Sciences, and his mentor Schunn, a professor of psychology as well as a ...

Barriers to obtaining gene expression profiling test heightened perceived value

2014-06-17

Barriers to obtaining gene expression profiling test heightened perceived value among patients, new study says TORONTO, June 17, 2014—Barriers to obtaining gene expression profiling tests heightened their perceived importance among patients with early breast cancer who were deciding whether to have chemotherapy, a new study says. Gene expression profiling tests, such as Oncotype Dx, analyze the patterns of 21 different genes within cancer cells to help predict how likely it is that a women's cancer will recur within 10 years after initial treatment and how beneficial ...

TRMM eyes rainfall in dissipating former Hurricane Cristina

2014-06-17

VIDEO: On June 14, NASA's TRMM satellite found rain falling at a rate of almost 97 mm (about 3.8 inches) per hour in the northwestern side of Cristina's eye wall where... Click here for more information. NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission or TRMM satellite passed over a dissipating former Hurricane Cristina and found it still contained heavy rain as it rapidly weakened. Hurricane Cristina had sustained winds of over 130 ...

Tropical depression Hagibis gets a second chance

2014-06-17

Tropical Depression Hagibis appeared out for the count when it made landfall along southeastern China on June 16, but moved back into the South China Sea where it regenerated and sped northeast through the East China Sea. The next day, the TRMM satellite noticed power had come back to Hagibis in the form of some moderate rainfall in the depression's northeastern quadrant. On June 17 at 10:30 UTC (6:30 a.m. EDT) the Tropical Rainfall Measuring Mission or TRMM satellite passed over the regenerated Hagibis and the Precipitation Radar instrument gathered data on the storm's ...

Sleep education program spurs preschoolers to snooze 30 minutes longer at night

2014-06-17

Ann Arbor, Mich. — Taking part in an educational sleep program resulted in a 30-minute average increase in sleep duration at a one-month follow-up for preschoolers, according to a new study from the University of Michigan. In the study, published in the journal SLEEP, families in two Head Start programs participated in the Sweet Dreamzzz Early Childhood Sleep Education Program™. The Detroit-area nonprofit organization, Sweet Dreamzzz, Inc. developed the program and offers it for free when funding allows. Head Start programs aim to give preschool opportunities to low-income ...

Dynamic spectroscopy duo

2014-06-17

From allowing our eyes to see, to enabling green plants to harvest energy from the sun, photochemical reactions – reactions triggered by light – are both ubiquitous and critical to nature. Photochemical reactions also play essential roles in high technology, from the creation of new nanomaterials to the development of more efficient solar energy systems. Using photochemical reactions to our best advantage requires a deep understanding of the interplay between the electrons and atomic nuclei within a molecular system after that system has been excited by light. A major ...

Why species matter

2014-06-17

UC Santa Barbara doctoral candidate Caitlin Fong travels to French Polynesia often but not for vacation. She goes there to study a coral reef ecosystem influenced by human impacts such as overfishing and nutrient pollution. Her work focuses not only on biological changes but also methods scientists use to determine within-group group responses to ecological processes. The findings are published in ESA Ecology, a journal of the Ecological Society of America. Fong and Peggy Fong, a professor in UCLA's Department of Ecology and Evolutionary Biology, conducted a study assessing ...

Not so fast -- our fishy friends can also feel pain

2014-06-17

Do you still believe that fish are dumb and cannot feel pain? That we do not have to worry much about how they are cared for or caught? Think again, says Culum Brown of Macquarie University in Australia, in a review article in Springer's journal Animal Cognition. The research notes that fish cognition and their sensory perception are generally on par with that of other animals. Brown therefore argues that more consideration should be given to fish welfare and anti-cruelty issues. The Australian researcher says that most people rarely think about fish other than as food, ...
