Abstract
OBJECTIVE: To describe a probable interaction between enteral feeds and levodopa leading to neuroleptic malignant-like syndrome (NMLS) in a polytrauma patient with Parkinson's disease (PD). CASE SUMMARY: A 63-year-old morbidly obese male polytrauma patient with PD and type 2 diabetes mellitus was admitted to our intensive care unit postoperatively. Enteral feeds were administered per nasogastric tube and provided 0.88 g /kg/day of protein based on ideal body weight (IBW). His PD medications (pramipexole, entacapone, and immediate-release levodopa/carbidopa 100 mg/25 mg, 1.5 tablets 4 times daily) were administered via nasogastric tube. To achieve better glycemic control, his enteral feeds were changed to a formula that provided 1.8 g/kg/day of protein based on IBW. In the following 24 hours, the patient's mental status deteriorated and he was reintubated. He developed a high fever (40.5 degrees C), leukocytosis, elevated serum creatine kinase (CK) (480-1801 units/L), and acute renal impairment. His enteral nutrition was changed to decrease protein intake to 1.0 g/kg/day based on IBW and he was given bromocriptine 5 mg 3 times daily via nasogastric tube. Within 24 hours, the patient's mental status improved, his temperature and CK decreased, and his renal function began to improve; the values returned to baseline levels on the 18th day of admission. DISCUSSION: Withdrawal or dose reduction of levodopa in patients with PD has been reported to precipitate NMLS, which is potentially fatal. Because dietary protein can decrease the absorp0tion of levodopa, a potential for an interaction between levodopa and enteral feedings exists, although published reports of such an interaction are limited. In this patient, the likelihood that a drug-nutrient interaction occurred between levodopa and enteral feedings is considered to be probable based on the Naranjo probability scale and the Horn Drug Interaction Probability Scale. CONCLUSIONS: Health-care professionals should be aware of the interaction between levodopa and protein content of enteral nutrition to avoid the occurrence of NMLS in patients with PD.

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
