humanity in ways that may have been unthinkable The current era of internet-facilitated bigger data, better previously. Millions of people creating and using content tools, and collective intelligence community computing is on the internet has generated large data sets and tools for accelerating advances in many areas ranging from artificial interpreting and manipulating these data that are intelligence to knowledge generation to public health. In the themselves recursive enablers of subsequent advance. health sector, data volumes are growing with genomic, phenotypic, microbiomic, metabolomic, self-tracking, and Artificial intelligence is one area that has realized other data streams. Simultaneously, tools are proliferating to substantial benefits from the new era of bigger data and allow individuals and groups to make sense of these data in better tools, particularly regarding machine learning, a participatory manner through personal health tracking anomaly detection (e.g.; fraud and spam), and natural devices, mobile health applications, and personal electronic language processing (e.g.; question answering systems like medical records. Health community computing models are emerging to support individual activity and mass IBM’s Watson). A quintessential example is Google’s success in spelling correction and language translation: crowdsourced health research studies. Participatory health progress in natural language machine learning allowed efforts portend important benefits based on both size and statistical methods to be applied to the large datasets that speed. Studies can be carried out in cohorts of thousands have arisen on the web (Halevy 2009). Simple data instead of hundreds, and it could be possible to apply findings from newly-published studies with near-immediate analysis techniques were successful after decades of speed. One operator of interventional crowdsourced health specially-designed algorithms showed little progress; a key research studies, DIYgenomics, has several crowdsourced point was finally having a very large corpus of data. health research studies in open enrollment as of January One effect of bigger data and better tools is that humans 2012 in the areas of vitamin deficiency, aging, mental themselves start to serve as a computing community, both performance, and epistemology. The farther future of intelligent health community computing could include as individual nodes and through mass collaboration. personal health dashboards, continuous personal health Individuals take in data, process it, and turn it back into the information climates, personal virtual coaches (e.g.; Siri network in new forms with added value. One public good 2.0), and an efficient health frontier of dynamic that has arisen through community computing and personalized health recommendations and action-taking. collective intelligence is the wikipedia (Fallis 2008). The annotation of street map data, creating crowdsourced Introduction

Another benefit of internet-based models is that a wide range of diverse participants can be engaged. Crowdsourcing can be used to obtain needed Copyright 2011, Association for the Advancement of Artificial Intelligence ( All rights reserved. participants, services, ideas, or content at low cost by soliciting contributions from a large group of people via organized studies have been interventional studies the internet. Better quality outcomes may be obtained designed and operated by citizen scientists, for example through wisdom-of-the-crowds benefits that accrue as those conducted by PatientsLikeMe patients, DIYgenomics people with diverse backgrounds analyze data and propose scientists, and Quantified Self individual novel interpretations. On average, the wisdom of crowds experimenters (Swan forthcoming 2012). The studies arrives at a better answer than any individual can provide, organized by DIYgenomics serve as a particular example including outperforming small groups of experts in making of the emerging collective intelligence health model that is decisions and predictions (Surowiecki 2004). becoming a complement to traditional clinical trials and defining a new ecosystem of preventive medicine (Swan Participatory Health: Bigger Data, Better Tools,

sector: the number of people participating is growing, the amount of data per person is growing, and the demand for DIYgenomics is a non-profit research organization easy accessibility and robust searchability of these data is established in 2010 for the purpose of organizing group growing. In 2009, it was estimated that all human-created collaboration health research studies with the goal of content to date comprised one zettabyte of information, but that within five years, it would be routine to be generating democratization of health experimentation, studies seek to one zettabyte of information in much shorter time frames, apply the wisdom of crowds to personal health particularly in the field of medicine, due to imaging and management. The generalized hypothesis for studies is that personalized profiling (Enriquez 2010) where billions of one or more genetic polymorphisms (e.g.; mutations) may data points per individual could become the norm (Hood lead to out-of-bounds phenotypic measures (for example, 2011). Better tools are also proliferating in participatory deficient vitamin B levels) that may be ameliorated with medicine and health 2.0, for example with self-tracking personalized intervention. Part of realizing preventive devices, mobile health applications, personal electronic medicine is establishing individualized baseline markers of medical records, health social networks, and crowdsourced wellness, for example a normal level of total cholesterol research studies. A next generation of tools will be for one person might be 130 mg/dL whereas for another required to integrate burgeoning health data streams 180 mg/dL would be normal. It is important for individuals (genomic, phenotypic, microbiomic, metabolomic, self- to have a sense of their own normal levels, and effective measurement tools for learning if there is deviation from these norms. At present, the focus of DIYgenomics studies Health community computing models may offer some is linking genetic mutation with phenotypic evidence and help, for example health social networks and crowdsourced personalized intervention. Additional health data streams health research studies are emerging to support both such as microbiome profiling and whole human genome individual activity and mass collaboration. Health social sequencing will be integrated as they become feasibly networks are online communities for individuals to discuss available to consumers. Seven studies have been launched and inform themselves about conditions, symptoms and in the areas of vitamin deficiency, aging, mental treatments, provide and receive support, track disease performance, and epistemology, and are available for progression, and potentially engage in health studies. At ongoing open enrollment. These studies are operated on present, there are dozens of health social networks, for the Genomera personal health collaboration and genome example, general communities like PatientsLikeMe which sharing platform, and links to the studies are available from has over 125,000 patients in 1,000+ conditions as of January 2012, and condition-specific communities like SugarStats for diabetes. Vitamin Deficiency Studies
Crowdsourced health research studies are investigative DIYgenomics has two vitamin deficiency studies projects conducted by individuals or groups for the purpose underway, investigating the possibility that one or more of understanding and/or improving a health-related issue. genetic polymorphisms (e.g.; mutations) may lead to Studies may be researcher-organized or participant- current blood marker levels that are already out-of-bounds organized. So far, researcher-organized studies have been per recommended levels, and that simple vitamin non-interventional studies organized by professional supplementation may be able to restore blood markers to researchers using crowdsourced cohorts or crowdsourced recommended ranges. The flagship study “Vitamin B-9 data as the input or research focus, for example studies and MTHFR variants” examines the potential role of organized by PatientsLikeMe and 23andMe. Participant- MTHFR genetic polymorphisms in vitamin B deficiency and homocysteine levels, and attempts to determine which results, and review their genetic data for the main vitamin supplement solutions are best from an individual D receptor gene polymorphism, rs10735810. Participants self-experiment regarding optimal supplement dosage, In the MTHFR gene (methylenetetrahydrofolate using Vitamin D Council guidelines recommending 1,000 reductase), two small variations in DNA (SNPs IU per 25 pounds of body weight as a starting dosage rs1801133/C677T and rs1801131/A1298C) may prevent (Cannell 2011). A person who weighs 150 pounds, for vitamin B9 (or folic acid) from being metabolized into its instance, would start taking 6,000 IU per day. A blood test active form (folate). Without this form of vitamin B, would test results after at least eight weeks, and then homocysteine can accumulate which may lead to supplement dosage can be modified. Each 1,000 IU nutritional deficiencies and symptoms associated with increase in vitamin D is estimated to produce an cardiovascular disease, diabetes, vascular damage, nerve approximate 10 ng/ml increase in vitamin D blood level. damage, and blood clots and pregnancy loss.

The study provides an opportunity to apply the dozens of genome-wide association studies (GWAS) The brain is able to adapt to the unexpected using an which relate to general and specific conditions of aging in inbuilt network that makes predictions about the world and a comprehensive preventive medicine approach. Genomic monitors the results of those predictions. An area at the data is linked with corresponding measures of phenotypic front of the brain, called the orbitofrontal cortex, plays a biomarkers and interventions.
