Abstract
Central venous catheterization for hemodialysis using double cannula has become the preferred central vascular form in acute cases. Moreover, in chronic cases, this form of vascular access has replaced the internal arterio-venous fistula whenever the latter is difficult to realize, or when patient's cardio-circulatory condition would discourage its creation. The central vascular access presents frequent complications, compromising their efficiency and duration. Tesio's central venous catheters were thoroughly studied and manufactured to overcome these complications, allowing a long life span of the vascular access. In this study 108 patients with Tesio's internal jugular central venous catheters were followed-up in the period 1990 to 1994. All patients underwent hemodialysis in Pordenone Center. Central venous access survival fluctuated between 93% and 82% in the first year and the fifth year respectively. However, access survival dropped to 32% after seven years. The accurate choice of the catheters' manufacturing material as well as the correct technical positioning has determined a significant increase in the vascular access survival, thanks to the important decrease in prevalence and seriousness of complications. We believe that the decreased accuracy in catheter management over time is the major cause of delayed loss of the central vascular access.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
