Internal Medicine for Primary Care – Porto

New MER international destination for 2026 (first Portugal offering, per MER's 'brand new destinations' page). Confirmed on official mercme.org page. Fresh full-catalog check for round 3 found this plus several other new MER city/resort locations (Santa Fe NM, San Antonio TX, Newport RI, Breckenridge CO, Park City UT, Mackinac Island MI) whose exact dates could NOT be reliably confirmed within this pass — some search-derived snippets for those cities conflicted with directly-fetched official page dates (e.g. an apparent Newport 2025 vs 2026 mismatch, Breckenridge Jan-2026 vs Jan-2027 mismatch), so those were deliberately excluded rather than guessed. Recommend a follow-up pass with direct, JS-rendered access to mer.org/conference-schedule to pin down exact dates for those additional cities.
