Hopkins researchers use diffusion MRI technique to monitor ultrasound uterine fibroid treatment

Johns Hopkins researchers have, for what is believed to be the first time, used a magnetic resonance imaging (MRI) technique called diffusion-weighted MRI (DWI), a technique that images the movement, or diffusion, of water molecules in tissues, to successfully determine the effectiveness of high-intensity focused ultrasound for treating uterine fibroids. Uterine fibroids are noncancerous tumors that line the uterine wall and can cause intense pain and bleeding. The study appears in the July edition of Radiology. more  

Survey uncovers surprising attitudes towards HIV vaccine research

A survey of U.S. adults has found that a majority believe that HIV vaccines are the best hope for controlling the global AIDS epidemic and are confident such vaccines can be made. But while most of those surveyed felt it personally important to help support HIV vaccine research, a majority expressed reluctance to support a friend or family member's participation in an HIV vaccine clinical trial. more

Patient's genes can predict response to chemotherapy for breast cancer

Breast cancer patients could find out whether they will respond positively to chemotherapy treatment by testing for the activity of certain genes. In a study published today in the Open Access journal, Journal of Translational Medicine, researchers analysed the genes expressed in the tumours of eighty-three patients with primary breast cancer. more  

Hospital characteristics play a role in use of do-not-resuscitate orders

Hospital characteristics, including size, non-profit status and affiliation with a university, appear to be associated with use of do-not-resuscitate orders (DNR) in California, independent of the patient's characteristics, according to a study in the August 8/22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. more

First guidelines to focus on postoperative atrial fibrillation 

The American College of Chest Physicians (ACCP) released today the first evidence-based clinical practice guidelines for the prevention and management of postoperative atrial fibrillation (AF) after cardiac surgery. Published in the August issue of CHEST, the peer-reviewed journal of the ACCP, the guidelines offer specific recommendations on cardiac pacing, anticoagulation therapy, pharmaceutical prophylaxis, intraoperative interventions, and pharmacologic control of ventricular rate and rhythm. Atrial fibrillation, or irregular heartbeat, is a common condition that occurs increasingly with age and is one of the most frequent complications of cardiac surgery. more

Study finds depression and fatigue not associated with cancer risk  

Feeling depressed and fatigued does not increase a person's risk for cancer, according to a new study. Severely exhausted people, however, do engage in behavior that is associated with a higher cancer risk. The study, published in the September 15, 2005 issue of Cancer, is the first prospective study using the "vital exhaustion" questionnaire to investigate this link. more
