Seems every article imported with Fatameh (14 Million currently) has this issue:
Any plans to fix this?
Yes, there are some plans but I don't think consensus on what should be done. There is a ticker for it here: https://github.com/SuLab/WikidataIntegrator/issues/20
Basically the problem is we're using PubMed as the data source and according to them the title does end in a period. Its difficult to know when we should remove it; and in any case we probably want to find a reference to support the version without a period.
