Highlight HEALTH 2.0

At the 2009 JavaOne Conference in June, Visuvi Inc., a Redwood City, California-based company developing visual search solutions, announced a Java-based visual search technology that integrates a JavaFX front-end with PathXchange, a Web 2.0 pathology portal. The Visuvi Java application enables medical professionals to take a digital biopsy image of 50,000 x 60,000 pixels (that’s 3000 mega pixels) and search medical images in leading databases for similarities.

The power of this technology is that the medical images in the databases have corresponding case information. Thus, images that are found to be similar also provide information on patient diagnosis, treatments, outcomes, etc. This is particulary useful in oncology since, in more cases than you’d expect, pathologists disagree on whether a particular image shows cancer or not [1-3]. By comparing pathology images, the technology greatly accelerates the review process and allows a diagnosis to be more objective than what is currently done.

Check out their demo at the conference in the video below. James Gosling (the inventor of Java) was clearly impressed with the significance of the technology. Chris Boone, CEO and president of Visuvi, and Florian Brody, VP Marketing, highlighted and captured a section of an actual prostate cancer biopsy image and searched 90,000 images in 0.3 seconds to find related patient cases.

PathXchange is a not-for-profit professional networking portal for the global pathology community. PathXchange brings the field of pathology into the digital age with Web 2.0 features designed to promote exchange of pathological cases, knowledge and information, combining the elements of a case gallery, community content contribution and professional networking.

Cancer patients are using online support communities more than ever before. These sites offer both emotional and informational support, and empower patients by enabling them to talk with other patients who are facing similar issues. According to a new study, online support communities for cancers with a high survival rate contain a greater amount of emotional support than do online communities for cancers with a low survival rate [1]. Researchers at the University of Michigan Health System and VA Ann Arbor Healthcare System also found that online support communities for cancers with a low survival rate contained more informational support than did communities for cancers with a high survival rate.

The new study, presented last month at the 2008 annual meeting of the North American Primary Care Research Group [2], evaluated the differences in emotional and informational social support content in online communities for cancers with low and high survival rates.

The researchers analyzed over 3,500 messages from 587 individuals in eight online support communities located within Yahoo!Groups and the Association of Cancer Online Resources (ACOR) websites for four different types of cancer with low or high five-year survival rates. Across all communities, there was a greater amount of emotional support than informational support.

High survival rate communities contained a greater proportion of emotional support than low survival rate communities (65% vs. 55%). In contrast, low survival rate communities contained a greater proportion of informational support than high survival rate communities (33% vs. 25%).

Participants in the study were members of support communities for four different types of cancer: lung cancer, melanoma, pancreatic cancer and thyroid cancer. They participated in eight different online communities and were all reviewed under the same time period.

According to the primary author of the study, Lorraine Buis, Ph.D. [3]:

When primary care providers refer individuals to online communities for support, they should be aware that there might be differing amounts of support based on the survival rate of a particular cancer.

According to the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) Cancer Statistics Review, which reports the most recent cancer incidence, mortality, survival, prevalence and lifetime risk statistics, from 1975 to 2005 cancer patients with thyroid cancer and melanoma of the skin had high survival rates (96.6% and 91.2% respectively) while lung cancer and pancreatic cancer had low survival rates (12.1% and 5.1% respectively) [4].

In addition to helping patients, online support communities help family and friends cope with the struggles that cancer presents. This is the first study to assess the influence of cancer patient survival rates on social support content in online communities for cancer.

A number of patient social networks are listed in the Highlight HEALTH Web Directory.
