Light therapy effectively treats early prostate cancer

A new non-surgical treatment for low-risk prostate cancer can effectively kill cancer cells while preserving healthy tissue, reports a new UCL-led phase III clinical trial in 413 patients. The trial was funded by STEBA Biotech which holds the commercial license for the treatment. (more…)

Men who forgo aggressive treatment for prostate cancer don’t receive appropriate monitoring

UCLA study finds most patients who choose “active surveillance” don’t follow up with tests and office visits

An increasing number of men diagnosed with low-risk prostate cancer are opting for active surveillance – closely monitoring their cancer – rather than aggressive treatment to avoid the debilitating potential side effects of surgery and radiation, such as erectile and urinary dysfunction. (more…)

STD may heighten risk of prostate cancer

Could a common sexually transmitted infection boost a man’s risk for prostate cancer?

In a new study, Patricia Johnson, a professor of microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA, explored the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.

A new device deciphers the language of cells

A biomedical engineer listens in on what proteins are saying.

As inventions go, Yale biomedical engineer Rong Fan’s entry into the innovation sweepstakes is not much to look at. Fan’s device, impressively named a single-cell, 45-plex protein secretion measurement platform, seems to be little more than a sandwich of two sheets of clear silicon rubber the thickness of window glass, each sheet a bit smaller than a credit card and bearing a smaller, darker rectangle divided into 14 vertical sections. It has no flashing lights, no intriguing noises, no moving parts, no signs of Applesque high design. Indeed, the object, displayed in Fan’s bustling laboratory on the first floor of the Daniel L. Malone Engineering Center, doesn’t appear to be doing anything at all. (more…)

UCLA researchers create Google Glass app for instant medical diagnostic test results

A team of researchers from UCLA’s Henry Samueli School of Engineering and Applied Science has developed a Google Glass application and a server platform that allow users of the wearable, glasses-like computer to perform instant, wireless diagnostic testing for a variety of diseases and health conditions.

With the new UCLA technology, Google Glass wearers can use the device’s hands-free camera to capture pictures of rapid diagnostic tests (RDTs), small strips on which blood or fluid samples are placed and which change color to indicate the presence of HIV, malaria, prostate cancer or  other conditions. Without relying on any additional devices, users can upload these images to a UCLA-designed server platform and receive accurate analyses — far more detailed than with the human eye — in as little as eight seconds.

Prostate cancer: moving beyond ‘watchful waiting’

Prostate cancer is the second-leading cause of cancer death in American men: the American Cancer Society expects the disease will claim nearly 30,000 lives in 2013. The disease mainly affects older men—the median age of diagnosis is 67—and it’s a slow-growing cancer, so most men diagnosed with the disease are likely to die of other causes.

Brad Davis, a veterinarian with a family history of prostate cancer, was diagnosed at age 54. A blood test he had taken showed elevated levels of prostate-specific antigen (PSA), a protein that may indicate the presence of the disease, and a biopsy confirmed the diagnosis. (more…)
