Real-time radiation monitor can reduce radiation exposure for medical workers

DALLAS - Dec. 16, 2014 - It's a sound that saves. A "real-time" radiation monitor that alerts by beeping in response to radiation exposure during cardiac-catheterization procedures significantly reduces the amount of exposure that medical workers receive, UT Southwestern Medical Center researchers found.

Back to the future? Past global warming period echoes today's

Back to the future? Past global warming period echoes today's

The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, researchers have found.

The findings mean that the so-called Paleocene-Eocene thermal maximum, or PETM, can provide clues to the future of modern climate change.

The good news: Earth and most species survived.

Traffic stops and DUI arrests linked most closely to lower drinking and driving

  • American states got tough on impaired driving in the 1980s and 1990s, but restrictions have flat lined.

  • A new study looks at associations between levels and types of law-enforcement efforts and prevalence of drinking and driving.
  • The number of traffic stops and DUI arrests per capita had the most consistent and significant associations.

Density of alcohol outlets in rural areas depends on the town's average income

Alcohol outlets tend to be concentrated in lower-income areas. Given that alcohol-related problems such as trauma, chronic disease, and suicide occur more frequently in areas with a greater density of alcohol outlets, lower-income populations are exposed to increased risk. This study examines the distribution of rural outlets in the state of Victoria, Australia, finding towns had more outlets of all types where the average income was lower and where the average income in adjacent towns was higher, and that this was consistent with retail market dynamics.

Low-glycemic index carbohydrate diet does not improve CV risk factors, insulin resistance

Effectiveness of drugs to prevent hepatitis among patients receiving chemotherapy

Among patients with lymphoma undergoing a certain type of chemotherapy, receiving the antiviral drug entecavir resulted in a lower incidence of hepatitis B virus (HBV)-related hepatitis and HBV reactivation, compared with the antiviral drug lamivudine, according to a study in the December 17 issue of JAMA.

How music class can spark language development

EVANSTON, Ill. - Music training has well-known benefits for the developing brain, especially for at-risk children. But youngsters who sit passively in a music class may be missing out, according to new Northwestern University research.

In a study designed to test whether the level of engagement matters, researchers found that children who regularly attended music classes and actively participated showed larger improvements in how the brain processes speech and reading scores than their less-involved peers after two years.

Mild memory & thinking issues: What works, what doesn't? U-M experts weigh the evidence

ANN ARBOR, Mich. -- For up to one in five Americans over age 65, getting older brings memory and thinking problems- along with the embarrassment of not being as "sharp" as they once were, and the worry that it will get much worse.

They might just call it "getting older". But officially, when memory or cognitive problems don't interfere significantly with daily living, doctors call them mild cognitive impairment, or MCI.
