Grass-roots entrepreneurship complements traditional top-down innovation in lung and breast cancer.

The majority of biomedical research is funded by public, governmental, and philanthropic grants. These initiatives often shape the avenues and scope of research across disease areas. However, the prioritization of disease-specific funding is not always reflective of the health and social burden of each disease. We identify a prioritization disparity between lung and breast cancers, whereby lung cancer contributes to a substantially higher socioeconomic cost on society yet receives significantly less funding than breast cancer. Using search engine results and natural language processing (NLP) of Twitter tweets, we show that this disparity correlates with enhanced public awareness and positive sentiment for breast cancer. Interestingly, disease-specific venture activity does not correlate with funding or public opinion. We use outcomes from recent early-stage innovation events focused on lung cancer to highlight the complementary mechanism by which bottom-up "grass-roots" initiatives can identify and tackle under-prioritized conditions.

A Systems Approach to Healthcare Innovation Using the MIT Hacking Medicine Model.

MIT Hacking Medicine is a student, academic, and community-led organization that uses systems-oriented "healthcare hacking" to address challenges around innovation in healthcare. The group has organized more than 80 events around the world that attract participants with diverse backgrounds. These participants are trained to address clinical needs from the perspective of multiple stakeholders and emphasize utility and implementation viability of proposed solutions. We describe the MIT Hacking Medicine model as a potential method to integrate collaboration and training in rapid innovation techniques into academic medical centers. Built upon a systems approach to healthcare innovation, the time-compressed but expertly guided nature of the events could enable more widely accessible preliminary training in systems-level innovation methodology, as well as creating a structured opportunity for interdisciplinary congregation and collaboration.

Less noise, more hacking: how to deploy principles from MIT's hacking medicine to accelerate health care.

Medical technology offers enormous potential for scalable medicine--to improve the quality and access in health care while simultaneously reducing cost. However, current medical device innovation within companies often only offers incremental advances on existing products, or originates from engineers with limited knowledge of the clinical complexities. We describe how the Hacking Medicine Initiative, based at Massachusetts Institute of Technology has developed an innovative "healthcare hackathon" approach, bringing diverse teams together to rapidly validate clinical needs and develop solutions. Hackathons are based on three core principles; emphasis on a problem-based approach, cross-pollination of disciplines, and "pivoting" on or rapidly iterating on ideas. Hackathons also offer enormous potential for innovation in global health by focusing on local needs and resources as well as addressing feasibility and cultural contextualization. Although relatively new, the success of this approach is clear, as evidenced by the development of successful startup companies, pioneering product design, and the incorporation of creative people from outside traditional life science backgrounds who are working with clinicians and other scientists to create transformative innovation in health care.

Development of a biochip using antibody-coated gold nanoparticles to detect specific bioparticles.

This study developed a method of detecting bioparticles such as Salmonella that exist in the biological samples. The method employed a substrate with interlaced comb-like electrodes into which the mixtures of biological samples and antibody-coated gold nanoparticles were added. The alternative signals with appropriate frequency bands were then conducted into the comb-like electrodes to change the dielectrophoresis force. The gold-modified Salmonella can be adsorbed on the edges of the electrodes and isolated from various biological samples. The impedance of the adsorbed Salmonella on the edges of the electrodes was measured and comparison of the impedance between the electrodes with and without Salmonella can quantify the amount of the adsorbed Salmonella.

Detection of specific bioparticles using antibodies-coated gold nanoparticles and dielectrophoretic impedance measurement.

In this study, we developed an easy and quick test capable of identifying specific bacteria in one hour. The protocol was established based on the measurement of bacteria quantity on a biochip with comb-like electrodes. Gold nanoparticles coated with anti-Salmonella antibody were used to enhance the dielectrophretic property of Salmonella spp. on the biochip to facilitate the sensitivity.
