Researchers gain new insight into cancer metastasis

Few things are as tiresome as house hunting and moving. Unfortunately, metastatic cancer cells have the relocation process down pat. Tripping nimbly from one abode to another, these migrating cancer cells often prove far more deadly than the original tumor.

Appropriate use criteria for coronary revascularization

If you're committed to fitness, the decision to climb a couple of flights of stairs rather than take the elevator is clear. But if you develop chest pain on the way up, deciding how to treat the symptoms of clogged arteries in your heart is much more complicated.

Many teens discuss health risk behaviors on social networking websites

In a pair of related studies released by Seattle Children's Research Institute and published in the January 2009 issue of Archives of Pediatric & Adolescent Medicine , researchers found that 54 percent of adolescents frequently discuss high-risk activities including sexual behavior, substance abuse or violence using MySpace, the popular social networking Web site (SNS).

Carotid endarterectomy provides better short-term results than carotid artery stenting in patients with carotid artery disease

Carotid endarterectomy (CEA) yields better short-term results than carotid artery stenting (CAS) in patients with carotid artery disease, according to a 30-day outcomes report from the Society for Vascular Surgery (SVS) Vascular Registry for Carotid Procedures, published in the January 2009 issue of the Journal of Vascular Surgery, by the Society for Vascular Surgery.

Discovery of new syndrome associated with severe congenital neutropenia

A team of scientists has discovered a new syndrome associated with severe congenital neutropenia (SCN), a rare disorder in which children lack sufficient infection-fighting white cells, and identified the genetic cause of the syndrome: mutations in the gene Glucose-6-phosphatase, catalytic subunit 3 (G6PC3).

First-degree family history of prostate cancer does not affect some treatment outcomes

In a first of its kind study, a first-degree family history of prostate cancer has no impact on the treatment outcomes of prostate cancer patients treated with brachytherapy (also called seed implants), and patients with this type of family history have clinical and pathologic characteristics similar to men with no family history at all, according to a January 1 study in the International Journal of Radiation Oncology*Biology*Physics , the official journal of the American Society for Radiation Oncology.

Why prostate cancer patients fail hormone deprivation therapy

The hormone deprivation therapy that prostate cancer patients often take gives them only a temporary fix, with tumors usually regaining their hold within a couple of years.

Discovery of potential important pathway for controlling cell loss and survival in Parkinson's disease

Neurologists have observed for decades that Lewy bodies, clumps of aggregated proteins inside cells, appear in the brains of patients with Parkinson's disease and other neurodegenerative diseases.

Specialized kidney transporter improves transplant results

A landmark study published in the New England Journal of Medicine (NEJM) demonstrates that use of a specially-designed machine to store kidneys for transplantation offers significant benefits in kidney survival and function when compared to those stored in a traditional "ice box", or cold storage.
