Want to improve your relationship? Do the dishes because you want to
If you do something positive for your mate, does it matter why? The answer is yes, according to new research from University of Rochester research assistant professor Heather Patrick. She will unveil a study at a Toronto conference later this month that shows both small sacrifices, like doing the dishes for your partner, and big ones, like moving across the country for a new job he or she really wants, mean more if you do them because you genuinely want to.

Obesity increases risk of injury on the job
Researchers at the Johns Hopkins Bloomberg School of Public Health Center for Injury Research and Policy report that having a body mass index in the overweight or obese range increases the risk of traumatic workplace injury. The results were published by the American Journal of Epidemiology.

Studies assess effectiveness of serotonin and nerve stimulants on irritable bowel syndromes
Studies have shown that gastrointestinal tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome or constipation. Two studies presented today at Digestive Disease Week 2007 take a closer look at GI stimulation, including one examining the role of serotonin and reactions to certain types of foods and another looking at the potential therapeutic value of nerve stimulation for constipation. DDW is the largest international gathering of physicians and researchers in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery.

Enhanced MR-guided focused ultrasound guidelines demonstrate improved efficacy and durability
Data released today show that MR-guided focused ultrasound is a more effective option for a broader population of uterine fibroid sufferers. In a poster presented today at the American College of Obstetrics and Gynecology annual meeting in San Diego, Phyllis Gee, M.D., of the North Texas Uterine Fibroid Institute in Plano, Texas, showed that women undergoing MRgFUS experience rapid and sustained relief from their condition and have a reduced need for alternative, invasive treatments in the future.

New Mayo Clinic MRI technology enables noninvasive liver diagnoses
Two recent Mayo Clinic studies have found that magnetic resonance elastography (MRE), a new imaging technique invented at Mayo Clinic, is an accurate tool for non-invasive diagnosis of liver diseases. The findings will be presented this week at the International Society for Magnetic Resonance in Medicine Annual Meeting in Berlin, Germany, and Digestive Disease Week 2007 in Washington, D.C.

Sleepless for science: Flies show link between sleep, immune system in Stanford study

Participation by physicians in the voting process is unimpressive
With healthcare issues returning to the forefront of public attention, physicians might be expected to participate in elections at a relatively high rate. In the first study of physician voter turnout, to be presented at the 2007 Society for Academic Emergency Medicine Annual Meeting, evidence suggests that physician participation in the political process has declined over the past few decades.

Leading prevention researchers meeting in Washington, D.C., May 30-June 1, 2007

Alarming acceleration in CO2 emissions worldwide
Between 2000 and 2004, worldwide CO2 emissions increased at a rate that is over three times the rate during all of the 1990s. The accelerating growth rate is largely due to the increasing energy intensity of economic activity and the carbon intensity of the energy system, with increases in population and in per-capita gross domestic product. The increases in energy and carbon intensity constitute a reversal of a long-term trend toward greater energy efficiency and reduced carbon intensities.

Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients
University of Pittsburgh researchers have identified a specific genetic profile in a group of idiopathic pulmonary fibrosis (IPF) patients that indicates a far more rapid progression to complete pulmonary failure and death without a lung transplant in comparison with other patients. In collaboration with pulmonary scientists in Mexico and California, Pittsburgh researchers found 437 differentially expressed genes. Most IPF patients live about five years following diagnosis with the chronic lung disease.

Increasing radiation dose shortens treatment time for women who choose breast sparing treatment
Radiation therapy after lumpectomy for early-stage breast cancer can be safely delivered in higher daily doses to greatly reduce treatment time. This conclusion of a new Fox Chase Cancer Center study is good news for women who might opt to have a mastectomy instead of a lumpectomy because of the time commitment needed for the usual six-week radiation course with the breast-sparing surgical option.

Data showed improved quality of life and patient satisfaction with SYMBICORT
New data demonstrated that the combination asthma therapy, SYMBICORT(budesonide/formoterol fumarate dihydrate), led to significant improvements in health-related quality of life and greater patient-reported satisfaction with asthma treatment, versus its monocomponents (budesonide or formoterol) or placebo. The results from these two 12-week randomized, double-blind trials were presented at the American Thoracic Society 2007 International Conference held in San Francisco, May 18-23.

When lava flows and glaciers recede, predicting how species take over
When fire, clearcutting, lava or receding glaciers create empty habitat, species arrive to form a new ecological community. Adverse conditions -- such as isolation of the new community or an unfavorable climate -- may hinder the arrival of new species and change the pattern of succession. This study provides a framework to understand why communities mature at different rates, which is fundamental to managing clear cuts or fire.
