Researchers from McGill University and other cancer research centers in Canada and the US will begin testing a technology that uses a biochip microarray to tailor chemotherapy to the genetic makeup of a specific malignancy, they reported at the American College of Surgeons Annual Clinical Congress held Oct. 10-15 in San Francisco.
Scientists at the Medical College of Virginia have genetically manipulated liver cells to function as pancreatic islets and produce insulin. The researchers are now working to alter the liver cells further so that they will release insulin in response to changes in blood sugar levels, they said at the American College of Surgeons Annual Clinical Congress held Oct. 10-15 in San Francisco.
Surgeons at the University of Colorado, Denver, have shown for the first time that raloxifene (a new class of drugs known as selective estrogen receptor modulators) exerts a protective effect on blood vessels. An animal study that mimics the development of atherosclerosis in women who have undergone menopause showed that raloxifene prevented an increase in intimal hyperplasia in the aorta, they reported at the American College of Surgeons Annual Clinical Congress held Oct. 10-15 in San Francisco.
Experimental studies have found that hepatocyte growth factor reduced inflammatory bowel disease in animals to the point where most visible lesions in the bowel were eliminated, they reported at the American College of Surgeons Annual Clinical Congress held Oct. 10-15 in San Francisco.
Studies conducted at the Comprehensive Breast Cancer Center at the University of South Florida indicate that low-dose radioactive seeds may prove to be an accurate and safe new way of taking biopsies from lesions in the breast. Surgeons inserted low-dose radioactive seeds adjacent to suspicious nonpalpable lesions, they reported at the American College of Surgeons Annual Clinical Congress held Oct. 10-15 in San Francisco.
Research conducted at the Greenville (SC) Hospital System is showing the connection between rapid and excessive weight loss following minimally invasive surgical treatment of morbid obesity and the risk of internal hernia. The researchers believe that surgeons who operate on morbidly obese patients and physicians who treat these patients following the operation should be aware that rapid weight loss could be a sign that monitoring for internal hernia is advisable.
Researchers from Columbia and Cornell Universities (NY) have been studying whether patients in poor countries suffering from certain medical conditions could benefit from surgical treatment. The results of the study could potentially lead to the implementation of surgical infrastructure in countries where none currently exists.
Surgeons from Oregon Health and Science University are finding that both patients and the environment can be protected by the recycling of solid waste and conservation of energy use in the operating room. The researchers have found that sustainability efforts on a grand scale can have a major impact and do not have to interfere with patient care.
Findings from a pair of studies conducted by researchers at Emory University School of Medicine show that physicians often overestimate the literacy levels of their patients relative to the use of screening tools created to optimize office visits. The studies have led the researchers to believe that issues related to health literacy and illiteracy need to be addressed.
Researchers from the University of Washington have concluded that a large number of trauma patients suffer from sexual dysfunction long after their initial injury. According to the researchers, the condition, which does not appear to be related to certain risk factors, is one that more practitioners and patients should be aware of.
