* Problems within the Julia ecosystem

+ Julia needs more database connectivity to more easily do operations research

+ Databases are a pain point and composing with other aspects of the ecosystem

+ Interoperability within Julia and other sorts of resources

+ I end up doing the bare minimum in SQL

+ Do we have RAM?

+ Can we pull this into the Julia ecosystem?

+ Crank up the RAM! But only so much scaling

+ Minimal SQL writing

+ Searchlight.jl: Julia ORM layer within

+ Is Genie like a shiny?

+ No, more of a full-stack

+ Goes beyond just visualization dashboards

+ Sequencing data

+ Equally data

+ Everyone uploads data in slightly different ways

+ Make simple ways to pull that data

+ R Conductor --> JuliaConductor?

+ Would make genomic pipelines within Julia pipelines a lot easier

+ We need to understand the underlying structures

+ One of the big pain points

+ Often to have roll your own

+ EpiR --> EpiJ?

+ Power calculators

+ Co-founder of start-up

+ Found unmet need for remote monitoring for neuotropenia

+ Non-invasive screen for neutropenia

+ Device runs Julia

+ Pain points:

+ Testability of hardware

+ LOTS of CI -- bit of a pain

+ How much repetition happens in CI

+ Part of the problem for these problems:

+ There are still going to be folks who use the same organizations

+ Overcoming inertia to do the same or similar things in Julia

+ Wrapping around Julia?

+ Bringing it into the R ecosystem

+ Leading to big impacts for callable things from R by having smaller static binaries

+ Wrapping Julia packages in R

+ N3C -- National COVID Cohort Collaborative

+ Went to many healthcare systems across the US to get COVID data

+ Shelled out to Palantir

+ Open source tools within the ecosystem

+ JuliaHub has Boeing board member

+ Trusted within security community

+ Could help in this situation

- Thoughts on how to address some of these problems

* Using other packages outside of Julia

+ If you have some way to wrap around it

+ Getting support

+ PythonCall.jl or RCall.jl

+ Not clear how to make this compositional

* The paradox of compositionality

+ Blog posts go a huge ways to solving problems

+ Tutorials showing how things can be combined together

+ Promotional type material

+ Nice docs are *nice*

* The Julia Blog itself

+ Mentions JuliaBloggers but doesn't help with guiding users to read

+ Blogs need to go on as official blogs

+ Julia Forem -- is it maintained?

+ Hook into the tags from blogs

+ Cross-posting where appropriate

* How to learn Julia within the context of health

+ Carpentries for learning resources

## Meeting Summary

**In Attendance:** Jacob Zelko, Dilum Aluthge, Asher Wasserman, Fareeda Abdelazeez, Kyle Beggs

**Location:** Virtual

**Summary:** First JuliaHealth community call to meet other Julians, learn how we can galvanize the Juliahealth Community, and open discussion on paths forward

**Keywords:** #data #analysis #hemodynamics #omop #machine #learning

## Agenda

1. Introductions

2. What people are using Julia for in health research

3. Selected topics and state within the Julia ecosystem:

1. Observational Health
2. Medical Imaging
3. Machine Learning and Health
4. Interoperability Standards
5. Drug Discovery

4. Standard Interfaces

## Meeting Outcomes

### Short-Term Outcomes

- @Dilum finds out how to live stream JuliaHealth BoF

### Long-Term Outcomes

## Meeting Notes

1. Introductions

1. Dilum Aluthge – MD/PhD Student Brown University (BCBI), PumasAI

1. Julia Community Involvement

1. Pkg
2. General Registry
3. Continuous Integration

2. JuliaHealth and beyond

1. Originally created JuliaHealth to bring people together in health
2. BioJulia folks are a great source of inspiration for packages!

3. Birds of a Feather!!! COME VISIT! – Friday July 28th, 4PM EST in Boston, MA!

2. Asher Wasserman – Astronomy PhD, Data Scientist in BioTech

1. Julia Community Involvement

1. Differential Equations
2. One off deployments

3. Fareeda Abdelazeez – GSoC JuliaHealth (First GSoC Student!!!!!)

1. Julia Community Involvement

1. Observational Health tooling JuliaHealth!

4. Kyle Beggs – Software Engineer in small Optics company, Finishing PhD in MechE

1. Julia Community Involvement

1. PDEs
2. Hemodynamics research focus
3. Take advantage of these tools for imaging, segmentation

2. What people are using Julia for in health research

1. Asher: Cancer patient data

1. PDFs and other data formats 

1. CDA documents

2. How to structure this ad hoc type of data into common data model

3. Developing processes to automatically make these documents useful

4. How do we clean the data to match actual reality

5. How do we make this data actionable/useful

6. Could match towards goals of OHDSI/observational health

1. Analyses at population level?
2. Outcome propensity scores?
3. Patient phenotype development?

7. Role of Julia:

1. Mainly as a scripting language

2. Supplement to a lot of SQL scripting (FunSQL discovered)

3. Python is generally being deployed because of software devs

1. How to not crash AWS, etc.

4. Julia deployment for risk (?)

5. Survival Analysis in Julia; lifelines in Python otherwise

2. Kyle: Vascular Surgical Planning

1. Unobvious on where to place graft, etc – educated guesses

2. Creating a tool to simulate operations

3. Why Julia?

1. Existing tools are open source but really GUI-driven

2. Integration across ecosystem would be even better for hemodynamics in Julia

3. Give a base to simulate the mechanics involved with this

1. JuliaFEM, etc. 

4. Mesh list methods

1. Point clouds
2. Main application is within hemodynamics

3. Fareeda: JuliaHealth GSoC Student

1. Working on OMOP Common Data Model

2. Standard model for observational health patient data

3. Develop infrastructure of JuliaHealth to work with OMOP CDM data

1. Improve DBConnector
2. OMOPCDMCohortCreator.jl – add tooling
3. OHDSIAPI.jl – creating interfaces for ATHENA/ATLAS

4. Patient Level Prediction tooling

1. Using MLJ algorithms

2. Attempting to solve a research question

1. Evaluate success of package

5. Stretch goals:

1. Cohort Quality and underlying data is “good”
2. Build support for OBDC connections

4. Overlap with other organizations

1. Doesn’t happen in a vacuum

2. Serving as a bridge between a bridge and a community between other groups

3. What should be JuliaHealth?

1. Bringing together people 

3. Selected topics and state within the Julia ecosystem:

1. Observational Health
2. Medical Imaging
3. Machine Learning and Health
4. Interoperability Standards
5. Drug Discovery

4. Standard Interfaces
