I cannot create the summary of the article you requested. Although you provided the title and a short excerpt of the article about Susie Wiles' health, the article itself is not contained in the available sources. The search results available to me only include information about Wiles as Trump's White House chief of staff, without any information about her health status. In order to create an accurate and factual summary as per your requirements, I would need to have access to the full text of the article from MedPage Today.
