Effects of vacuum-assisted closure and Drotrecogin alpha on inflammatory markers in severe acute pancreatitis
Bibliographic record
Abstract
In severe acute pancreatitis (SAP) inflammatory processes foster necrosis, cellular lysis and liberation of vasoactive substances associated with multiple organ failure. The effects of vacuum-assisted closure and Drotrecogin alpha on inflammatory cytokines were evaluated in SAP patients with infected necrosis. Methods: Forty-six patients were included in three groups: Group 1, necrosectomy and abdominal cavity washing; Group 2, necrosectomy plus vacuum-assisted closure (VAC), and Group 3, necrossectomy plus VAC plus Drotrecogin alpha. Immunoreactive IL-32, TNF-α, IL-6, TGF-β and IL-2 cytokines were quantified with ELISA method. Results: IL-32 was significantly increased in all patients, predominantly the non-survivor of Group 3 (p 0.0001). Group 2 maintained increased IL-32 levels throughout. Peak TNF-α was observed in non-survivors of Groups 1 and 2, with a frank tendency to decrease in Group 3. The IL-6 was increased, sustained throughout the study, peaking at the onset in non-survivors. At the end IL-6 tended to diminish, predominantly in survivors. TNF-α and IL-6 were significantly increased on hospitalization, with a maximum peak in non-survivors of all groups. Initial values of TGF-β were significantly increased in survivors of the three groups, and were significantly diminished in non-survivors; affecting pancreas regeneration and favoring systemic inflammation, with possible multiple-organ repercussions. IL-2 levels were elevated, predominantly in non-survivors of Group 1. There was positive correlation between the increase IL-32 and TNF-α, and negative correlation between the increase in TNF-α and decrease in TGF-β; and, a tendency for negative correlation between the IL-2 increased and TGF-β levels. Conclusion: We found a generalized, sustained inflammatory state that fosters a torpid outcome in SAP patients.

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.
