Gut bacteria boost immune response to tumors

One potent, immune-based treatment for cancer is total body irradiation (TBI). This approach first depletes the body of the population of immune cells known as lymphocytes and then involves the adoptive transfer of tumor-specific T cells to the patient.

Biologic agents valuable treatment option for patients with inflammatory bowel disease

The use of biologic agents for the treatment of inflammatory bowel disease (IBD) may benefit patients, but doctors need to consider the potential associated side effects in determining treatment course, according to a consensus paper published in this month's issue of Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.

PA catheterization uses decreases substantially in U.S.

Use of the pulmonary artery catheter decreased by 65 percent in the U.S. between 1993 and 2004, possibly due to growing evidence that this invasive procedure does not reduce the risk of death for hospitalized patients, according to a study in the July 25 issue of JAMA .

Prophylactic antibiotics for children with UTI not associated with reduced risk of recurrence

The use of prophylactic antibiotics, which involves daily administration of antibiotics to children after an initial urinary tract infection, is not associated with reduced risk of recurrent urinary tract infections, but is associated with an increased risk of resistant infections, according to a study in the July 11 issue of JAMA.

Diets high in salt may increase stomach ulcers

Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.

High salt intake increases gene activity in the ulcer-causing bacterium Helicobacter pylori

Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.

Complement receptor 3 sends a signal to dampen the immune system

Researchers from The Children's Hospital of Philadelphia and The University of Pennsylvania reported that complement receptor 3 (CR3), a protein found on cell surfaces, inhibits dendritic cells, the sentinels of the immune system, from setting off an alarm signal that brings on a full immune response.
