Anesthetic Management of a Child With Propionic Acidemia Complicated by Bacteremia and Severe Acute Respiratory Syndrome Coronavirus 2
Bibliographic record
Abstract
Propionic acidemia (PA) is a rare, multi-systemic inborn error of metabolism. PA results from an impaired activity of the mitochondrial enzyme, propionyl-CoA carboxylase (PCC). PCC holds an essential role in the catabolic pathways for odd-chain fatty acids, cholesterol side-chains and branched-chain amino acids. Errors in these pathways result in the accumulation of toxic metabolites that may advance into end-organ damage and dysfunction. Clinical manifestations of PA include relapsing courses of severe metabolic acidosis, concurrent viral or bacterial infection, episodic vomiting, gastroesophageal reflux disease (GERD), seizures, developmental delay, hypotonia, hyperammonemia, osteopenia, pancreatitis and cardiomyopathy. This case describes a 3-year-old boy with PA who presented with an acute metabolic crisis, precipitated by Staphylococcus epidermidis ( S. epidermidis ) bacteremia and severe acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) co-infection. He required anesthetic management for surgical removal of an infected central venous port. Anesthetic care for this patient presented the unique challenges of metabolic decompensation amidst infection with SARS-CoV-2. Options for anesthetic care for patients with PA have been elucidated in the literature. However, to our knowledge, this is the first case to describe anesthetic management in a PA patient with SARS-CoV-2. J Med Cases. 2021;12(4):152-156 doi: https://doi.org/10.14740/jmc3628

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
