How to keep CPG projects page on diagnijmegen.nl up to date

[keelinm]

The page at https://www.diagnijmegen.nl/research/pathology/ lists some projects from the CPG side. These can go out of date and for example we show projects that are finished some time ago. (The markdown of the pages themselves is the same markdown as used on the CPG site as I understood it, so the project text itself should be correct).
What is a good strategy to ensure that this page lists only more recent projects?
