I cannot provide the requested healthcare news digest focused on AI agents or agentic AI. The search results provided do not contain any news articles, research updates, or developments related to artificial intelligence agents or agentic AI systems in healthcare. While the search results include various healthcare-related news from the specified week (April 27 - May 5, 2026)—such as CorMedix's Phase III trial results, bilateral health agreements between the U.S. and partner countries, and medical equipment conferences—none of these sources address AI agents, machine learning agents, or agentic AI technologies. To provide an accurate and meaningful digest on AI agents in healthcare, search results specifically focused on AI developments, healthcare artificial intelligence implementations, or agentic AI applications would be required.
