Assessing prognosis and optimizing treatment in patients with postchemotherapy viable NSGCT (2/28/2008)

In nonseminomatous germ-celltumors (NSGCT), surgical resection of postchemotherapy residualmasses is universally recommended. These masses may harbor completenecrosis, teratoma, or viable malignant germ-cell tumors (GCT). Besides viable GCT, postchemotherapy residual masses can also harbor non-GCT cancer, especially in primary mediastinal NSGCT, and this so-called 'teratoma with malignant transformation' is associated with a dismal prognosis. In patients with postchemotherapy retroperitoneal and pulmonary lesions, discordant histologies between the two sites have been reported in approximately 30% of cases, thus justifying the removal of lesions from both sides of the diaphragm. However, the high pathological concordance rate (95%) between residual lesions from both lungs argues in favor of avoiding a contralateral thoracotomy when complete necrosis is identified in operative specimens from the one lung. ...> Full Article

Many Stroke, Heart Attack Patients May Not Benefit from Aspirin (2/27/2008)

Up to 20 percent of patients taking aspirin to lower the risk of suffering a second cerebrovascular event do not have an antiplatelet response from aspirin, the effect thought to produce the protective effect, researchers at the University at Buffalo have shown. ...> Full Article

Chicken Antibodies To Help Detect HER2 Breast Cancer (2/27/2008)

Generations of mothers have served up chicken soup to remedy the common cold, but now the therapeutic fowl may find use in diagnosis as well. Researchers at the National Institute of Standards and Technology (NIST), the National Cancer Institute (NCI) and the scientific research firm SAIC recently showed how chicken antibodies may one day improve the detection of an aggressive form of breast cancer. ...> Full Article

Ten Year Trends in Heart Failure (2/27/2008)

Conventional wisdom holds that as the U.S. population ages, the incidence of heart failure will continue to rise. A new study from Duke University Medical Center challenges part of that assumption, however, finding that heart failure is actually declining among the very elderly. Yet the number of heart failure cases overall continues to rise. ...> Full Article

First Chikungunya Animal Model Created (2/26/2008)

Researchers have developed the first animal model of the infection caused by chikungunya virus (CHIKV), an emerging arbovirus associated with large-scale epidemics that hit the Indian Ocean (especially the French Island of La Réunion) in 2005, later spreading to India, and Italy in 2007. Using this mouse model, scientists of the Institut Pasteur and INSERM determined which tissues and cells are infected by the virus in both the mild and severe forms of the disease it causes. ...> Full Article

Silica smart bombs deliver knock-out to bacteria (2/26/2008)

Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature. ...> Full Article

GP's Databases could identify tens of thousands with undiagnosed diabetes in UK (2/26/2008)

Researchers who examined blood test records in a survey of over 3.6 million patient records held by UK GP surgeries have found thousands of cases of probable undiagnosed diabetes. This could help identify tens of thousands of people with undiagnosed diabetes in UK. ...> Full Article

In Treating Stroke, Time Is of the Essence (2/24/2008)

Stroke is the third leading cause of death and the leading cause of major disability in the United States. Successfully treating ischemic stroke is dependent on how quickly treatment is given to break up the blood clots that clog key vessels and cause this type of disease. ...> Full Article

Scientists Reactivate Immune Cell Production in HIV-Infected Adults (2/24/2008)

Protein In Deer Tick Saliva Prevents HIV-1 From Attaching To T Cells (2/24/2008)

The HIV-1 virus cripples the human immune system by targeting white blood cells called T cells that form the body's first line of defense in fighting infections. A recent study by researchers from the University of Massachusetts Amherst shows that a protein found in the saliva of deer ticks prevents the HIV-1 virus from attaching to the surface of T cells, which is the critical first step in the virus' attack strategy. ...> Full Article
