Patients who have gastric cancer surgery followed by chemotherapy have an associated decreased risk of death and improved disease-free survival compared to patients who have surgery alone, according to an analysis of previous studies, reported in the May 5 issue of JAMA.

HOUSTON – Early life exposure to ultraviolet A light does not cause melanoma in a fish model that previously made that connection, scientists from The University of Texas MD Anderson Cancer Center reported today in the online Early Edition of the Proceedings of the National Academy of Sciences.

Caution required for Gulf oil spill clean-up

With millions of gallons crude oil being spewed into the Gulf of Mexico from the Deepwater Horizon oil spill, the focus now is on shutting down the leak. However, in the cleanup efforts to come, "extreme caution" must be exercised so as not to make a bad situation even worse, says a leading bioremediation expert with the Lawrence Berkeley National Laboratory (Berkeley Lab).

NEW ORLEANS, LA (May 4, 2010) – Endoscopic radiofrequency ablation is an effective treatment in eliminating Barrett's esophagus, an electronic "nose" offers a fast and effective way to detect inflammatory bowel disease, artificial replacements are now being developed to replace gastrointestinal tissue that is removed, and researchers find that endoscopic ampullectomy for treating ampullary adenoma (tumors of the bile duct) is more precise than surgery with fewer side effects. These are among the studies being presented at Digestive Disease Week® (DDW®) 2010.

Fragmented forests result in more snakes, fewer birds

About half of all bird nests don't survive due to predators, particularly in fragmented forest areas, but why? University of Illinois researchers monitored both the prey and predator to find an answer.

The hairs on the surface of water ferns could allow ships to have a 10 per cent decrease in fuel consumption. The plant has the rare ability to put on a gauzy skirt of air under water. Researchers at the University of Bonn, Rostock and Karlsruhe now show in the journal Advanced Materials (doi: 10.1002/adma.200904411) how the fern does this. Their results can possibly be used for the construction of new kinds of hulls with reduced friction.

SEATTLE—In a two-year evaluation at Group Health Cooperative, transforming primary care into a "patient-centered medical home" model paid off. Published in the May 2010 Health Affairs, the evaluation compared the medical home prototype to Group Health's other medical centers, showing:

Low levels of prenatal tobacco smoke exposure are associated with a higher risk of developmental problems for African American children than white children, according to new research from Cincinnati Children's Hospital Medical Center.

The findings were presented at noon ET Saturday, May 1, at the annual meeting of the Pediatric Academic Societies in Vancouver, Canada.

ANN ARBOR, Mich. — Severely obese adolescents may desire or potentially benefit from bariatric surgery. However, half of primary care physicians say they would not recommend the procedure to a patient under the age of 18, according to research published in Obesity Surgery.

Childhood obesity has increased dramatically since the 1970s. Obese adolescents are more likely to suffer from type 2 diabetes, hypertension, non-alcoholic steotohepatitis, sleep apnea, choleolithiasis and premature death as adults.

CHICAGO (May 3, 2010) – The results of new research results published in the April issue of the Journal of the American College of Surgeons show that a pilot pneumonia-prevention program significantly reduced postoperative pneumonia in a hospital surgical ward.

Breast magnetic resonance imaging (MRI) can detect breast lesions missed on mammography and ultrasound and help surgeons plan the most appropriate surgical treatment, improving patient outcomes, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.

Breast MRI offers valuable information about many breast conditions that cannot be obtained by other imaging modalities, such as mammography or ultrasound. As a result, it is increasingly being used for the preoperative evaluation of patients with newly diagnosed breast cancer.

The use of preoperative breast magnetic resonance imaging (MRI) prior to surgical intervention (for the treatment of breast cancer) can reduce the number of local (confined to the breast) cancer recurrences at follow-up, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA. MRI of the breast is a noninvasive medical test that helps physicians diagnose and treat breast cancer.

In younger patients, the estimated radiation risks associated with abdominal and pelvic computed tomography (CT) scans are twice those of older patients, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.

Short-term follow-up is often used to evaluate indeterminate breast lesions found on breast magnetic resonance imaging (MRI). However, researchers have found that indeterminate lesions (found in women with a high risk of breast cancer) should be evaluated sooner to exclude a possible malignancy, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.
