Global Access to OpenWHO's Online Learning Resources for COVID-19.
This poster presents the COVID-19 online learning response by the World Health Organization's (WHO) OpenWHO learning platform for health emergencies. Platform use shifted during the pandemic from being the highest in the WHO African and Eastern Mediterranean regions to the American and European regions. The largest traffic channels were search engines, social media and WHO websites.

An Analysis of the Growth in Uptake of OpenWHO's Online Learning Resources for COVID-19.
From 26 January - 21 April 2020, 9 online courses for COVID-19 were published on OpenWHO.org. The courses are available in 18 different languages, totalling 53 learning resources and more than 1.5 million course enrolments. ⋯ The number of enrolments increased significantly between 26 January and 21 April, with distinct spikes in growth preceded by important global milestones in the timeline of the outbreak. The surge in users demonstrates that the platform is serving as a source of digitized learning for COVID-19, helping meet the broad demand for outbreak-related information.

Application of Topic Modeling to Tweets as the Foundation for Health Disparity Research for COVID-19.
We randomly extracted publicly available Tweets mentioning COVID-19 related terms (n=2,558,474 Tweets) from Tweet corpora collected daily using an API from Jan 21st to May 3rd, 2020. We applied a clustering algorithm to publicly available Tweets authored by African Americans (n=1,763) to detect topics and sentiment applying natural language processing (NLP). ⋯ Compared to the COVID-19 related Tweets authored by others, positive sentiments, cohesively encouraging online discussions (e.g., Black strong 27.1%, growing up Blacks 22.8%, support Black business 17.0%, how to build resilience 7.8%), and COVID-19 prevention behaviors (e.g., masks 4.7%, encouraging social distancing 9.4%) were uniquely observed in African American Twitter communities. Application of topic modeling techniques to streaming social media Twitter provides the foundation for research team insights regarding information and future virtual based intervention and social media based health disparity research for COVID-19.

Development of a Mobile Digital Manikin to Measure Pain Location and Intensity.
Painful conditions are prevalent and substantially contribute to disability worldwide. Digital manikins are body-shaped drawings to facilitate self-reporting of pain. Some of them have been validated, but without allowing for recording of location-specific pain intensity and for use on a smartphone. ⋯ Test-retest reliability depended on the manikin's level of detail, but was generally high with most intraclass correlation coefficients âĽě0.70 and all similarity coefficients âĽě0.50. Participants found the manikin easy to use, but suggested clearer orientation (front/back, certain body locations) and would value additional feedback and diary functions. We will address these issues in the next version of the manikin before conducting a validation study.

Feasibility of Using EN 13606 Clinical Archetypes for Defining Computable Phenotypes.
Computable phenotypes are gaining importance as structured and reproducible method of using electronic health data to identify people with certain clinical conditions. A formal standard is not available for defining and formally representing phenotyping algorithms. In this paper, we have tried to build a formal representation of such phenotyping algorithm. ⋯ The EN13606 archetypes can be used to define the phenotype algorithm that basically identifies patients by a set of clinical characteristics in their records. Phenotype representations defined in EN 13606 do not satisfy all the desiderata proposed by Mo et al. and thus currently has a limited ability to define the computable phenotyping algorithms. Further work is required to make the EN13606 standard to fully support the objective.
