Abstract

fetched live from OpenAlex

The insertion of central venous catheters is a common bedside procedure performed in intensive care units. Here, we present a case of an 82-year-old man who underwent insertion of a central venous catheter in the internal jugular vein without perceived complications. Postprocedural radiographs showed rostral migration of the catheter, and computed tomography performed coincidentally showed cannulation of the jugular bulb at the level of the jugular foramen. To our knowledge, this is the first report to document migration of a central venous catheter from the internal jugular vein into the dural sinuses, as confirmed by computed tomography. The case highlights the importance of acquiring postprocedural radiographs for all insertions of central venous catheters to confirm catheter placement.

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.
