Elevated responsivity of reward regions in the brain increases risk for future substance use

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model.

CT imaging and serum LDH can predict survival in patients with metastatic melanoma

Combining CT imaging findings with baseline serum lactate dehydrogenase levels is showing promise as a way to predict survival in patients with metastatic melanoma being treated with anti-angiogenic therapy.

Study shows long-term exposure to fine particle matter air pollution is associated with atherosclerosis

The association between road traffic and heart disease has been suggested in several studies. In 2012 a large prospective cohort study from Denmark showed that traffic noise was significantly associated with risk of heart attack - for every 10 decibel increase in noise exposure (either at the time of the attack or over the five years preceding it) there was a 12% increased risk.

Study examines capabilities, limits of fMRI brain scans for detecting memories

Brain scans are increasingly able to reveal whether or not you believe you remember some person or event in your life. In a new study presented at a cognitive neuroscience meeting today, researchers used fMRI brain scans to detect whether a person recognized scenes from their own lives, as captured in some 45,000 images by digital cameras.

Study: Scanning patients as per standard trauma protocol generated hundreds of CT examinations

It is unnecessary to scan trauma patients based on a non-focused standard trauma CT protocol, if the patient is transferred for care after already undergoing a focused CT examination based on the patient's history and physical examination, a new study shows.

Practice of offering price information decreased overall use of lab tests by 9%, researchers find

Research at Johns Hopkins suggests that if hospitals would show physicians the price of some diagnostic laboratory tests at the time the tests are ordered, doctors would order substantially fewer of them or search for lower-priced alternatives.

New study finds that adding photo of patients to x-ray images can reduce wrong-patient errors

"X-rays can look alike, and if one patient's images are confused with another before the radiologist sees them, it can be difficult for the radiologist to determine there is a mismatch," said Dr. Srini Tridandapani, of Emory University and an author of the study.
