Abstract

fetched live from OpenAlex

A 47-year-old female with dyspnoea, poor blood pressure control and a family history of aortic disease presented with chronic type IA aortic dissection (with a maximal aortic diameter of 50 mm at the ascending aorta level). Anatomically, the patient presented with involvement of the brachiocephalic trunk and the left renal artery originated from the false lumen. The aortic valve was trileaflet but demonstrated severe eccentric insufficiency. Due to this constellation of findings, urgent surgical repair was indicated. Cardiopulmonary bypass was established centrally by direct true lumen cannulation with Seldinger echo-guided technique and cross-clamping between the distal ascending aorta and the proximal aortic arch (zone 0) performed while cooling. A period of high-moderate hypothermic circulatory arrest (26°C core temperature) with bilateral selective antegrade cerebral perfusion was utilized to complete the distal reconstruction. To repair the morphologically normal trileaflet but severely regurgitant aortic valve prolapsing in the dissected aortic root a valve-sparing aortic root replacement (David procedure) was performed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
