Scientists find new genetic test predicts prostate cancer risk

A genetic test to predict the risk for prostate cancer could reduce the need for repeat biopsies in men who have previously had negative biopsies.

In a clinical trial, 1,654 men who had prostate biopsies also had genetic studies conducted that looked for the presence of genetic variations that may have an association with prostate cancer risk.

The genetic test outperformed the widely used PSA (Prostate-Specific Antigen) test in assessing cancer risk. Because this genetic score is available at any time in a mans lifetime it could be used as a pre-screening test thus leaving aggressive PSA screening only to men at higher genetic risk.

The goal is to avoid, particularly in older men, unnecessary repeat biopsy procedures which carry with them the risk of infection and potential hospitalizations.

Findings appear in the journal of European Urology.

Inhibiting malaria parasite development

Malaria is responsible worldwide for more than 1.2 million human deaths annually. Severe forms of the disease are caused by the parasite Plasmodium falciparum transmitted to humans by the bite of female Anopheles mosquitoes. Lack of vaccines, together with the parasites ability to develop drug resistance, has thwarted eradication efforts.

An international team of scientists, led by researchers from the Department of Pediatrics at the UC School of Medicine, has identified the first reported inhibitors of a key enzyme essential for the development and survival of P. falciparum even in parasites that developed resistance to currently available drugs.
