Congrats to Dr. Philipp Merck for an impressive MD thesis! And congrats to the team, so proud to have been part of this. https://www.nature.com/articles/s41598-025-34088-y07 Jan 2026 12:10 +0000at://did:plc:roynrueaom6wapovv66vlvdk/app.bsky.feed.post/3mbtgqnhi5k2zhttps://bsky.app/profile/lohrmanf.bsky.social/post/3lyijzlyyjk2uExcited to share our new paper on pediatric non-tuberculous mycobacterial (NTM) lymphadenitis. Using advanced histology we identify patterns associated with favorable outcomes. We hope this helps refine NTM care.
