Abstract
<h3>Hypothesis</h3> Perioperative administration of a supplemented enteral formula may decrease postoperative morbidity. <h3>Design</h3> Randomized clinical trial. <h3>Setting</h3> Department of surgery at a university hospital. <h3>Patients</h3> One hundred ninety-six registered malnourished patients (weight loss ≥10%) who were candidates for major elective surgery for malignancy of the gastrointestinal tract. <h3>Intervention</h3> After randomization (n = 150), one group received postoperative enteral feeding with a standard diet within 12 hours of surgery (control group; n = 50). Another group orally received 1 L/d for 7 consecutive days of a liquid diet enriched with arginine, ω-3 fatty acids, and RNA (preoperative group; n = 50). After surgery, patients were given the same standard enteral formula as the control group. A third group orally received 1 L/d for 7 consecutive days of the enriched liquid diet. After surgery, patients were given enteral feeding with the same enriched formula (perioperative group; n = 50). <h3>Main Outcome Measures</h3> Postoperative complications and length of hospital stay. <h3>Results</h3> The 3 groups were comparable for baseline demographics, biochemical markers, comorbidity factors, and surgical variables. The intent-to-treat analysis showed that the total number of patients with complications was 24 in the control group, 14 in the preoperative group, and 9 in the perioperative group (<i>P</i>= .02, control group vs perioperative group). Postoperative length of stay was significantly shorter in the preoperative (13.2 days) and perioperative (12.0 days) groups than in the control group (15.3 days) (<i>P</i>= .01 and<i>P</i>= .001, respectively, vs the control group). <h3>Conclusion</h3> Perioperative immunonutrition seems to be the best approach to support malnourished patients with cancer.

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 it
