Abstract
Aim: To analyze the association between pleural effusion detected by chest point of care ultrasound (POCUS) and clinical outcomes in patients with septic shock admitted to an intensive care unit (ICU). Material and methods: A prospective evaluation of ICU patients with septic shock in whom chest POCUS was performed during the first 24 hours of diagnosis to identify the presence and characteristics of pleural effusion. Results: Of 45 patients with septic shock, 17 (38%) had pleural effusion. Mortality (13 vs 17 patients, p=0.44), as well as length of stay in ICU (11.0 vs 6.5 days, p=0.161) were similar among groups. However, there was a significant difference in the modified Nutrition Risk in Critically Ill (mNUTRIC) score between the pleural effusion (5.82±1.13) and non-pleural effusion groups (4.00±2.39, p=0.001). In addition, patients with pleural effusion required more days on mechanical ventilation than those without pleural effusion (10 vs 7, p=0.04). A subgroup analysis of chest POCUS characteristics between surviving and non-surviving patients with pleural effusion identified a higher median size of pleural effusion in the non-surviving group (3±2.16 cm vs 1.9±0.6, p=0.01). Conclusion: Pleural effusion in patients with septic shock is associated with high mNUTRIC scores and more days on mechanical ventilation. The larger the pleural effusion, the lower the survival rate.

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
