VIDAR-19 - Visualization of Covid-19 Risk Factors and Vaccine Side Effects

VIDAR-19

1. Introduction

With the COVID-19 disease, risk factors and co-morbidities are at stakes. Patients presenting such risks should indeed receive specific attentions and cares. The fact is that risk factors and co-morbidities reports are spread in many publications which does not provide a global view with actionable information.

In 2020, to cope with this problem, we developed a project, named VIDAR-19 (VIsualization of Diseases At Risk in CORD-19), able to extract automatically diseases from the ICD-11 in the coronavirus literature, and also diseases which might be considered as risk factors or co-morbidities.

In 2021, with the extraordinary worldwide efforts to provide a medical care for this new disease, the emphasis was on side effects of such rapidly designed vaccines. To cope with this new challenge, we extended VIDAR-19 so as to also extract vaccine side effects by using the techniques already used and developed for risk factors

This dashboard shows the outcome of the project. We present briefly below the different tabs. The online dashboard is available at: https://vidar-19.yotta-conseil.fr/

2. Disease Maps

This tab shows the share of branches in 3 sets of diseases: diseases with a code in ICD-11, diseases found in the corpus and diseases which might be considered as risk factors.

It shows also 2 treemap graphics which compare by branch (or sub-branch) the occurrences of diseases in the corpus vs. the occurrences of risk factors.

3. Document Frequency

This tab highlights the diseases, or the branches, for which the document frequency for risk factors, or side effects, is higher than the one for diseases in the corpus.

4. Search Documents

This tab enables to search for documents which contain a disease or a branch. Then it is possible to view the document source.

5. Search Variants

This tab enables to search for documents which contain a variant. A short list is available: D614G, E484K, E484Q, K417N, L452R, N439K, N501Y, P681H, P681R, R346K, S477N, V367F, Y453F. Then it is possible to view the document source.

6. CORD-19

This tab presents the CORD-19 documents dataset. It provides some insights into the processed documents from the selected datasets: How many documents? How many documents mentioning at least one disease? How many documents mentioning at least one disease which might be considered as a risk factor, or as a side effect? This tab enables also to select documents dealing with COVID-19 (virus or disease) or Vaccines.

7. ICD-11

This tab presents the ICD-11 documents dataset, i.e. the International Classification of Diseases from the World Health Organization. It gives some insights into the diseases which have been extracted: How many diseases in the database? How many diseases mentioned in the corpus? How many diseases which might be considered as risk factors?

8. Updates

As the final release of the CORD-19 dataset is scheduled for June 2, 2022. They won't be any update of the dashboard after this last release.

9. About this dashboard

The VIDAR-19 project has been implemented in Python. The graphical part of the project has been encapsulated into the Dash framework from plotly to get this web application. It is hosted on PythonAnywhere.

10. About the name VIDAR

VIDAR sounds like radar or sonar. Viðarr is also the name of a god in Norse mythology.
