Abstract
The polymyxins were discovered in the 1940s and represent a group of closely related polypeptide antibiotics obtained from Bacillus polymyxa, which was originally isolated from soil (1,2). Although they have been used extensively worldwide in topical otic and ophthalmic solutions for decades, the intravenous formulations were gradually abandoned in most parts of the world in the early 1980s because of the reported high incidence of nephrotoxicity (3‐5). As a result, the use of polymyxin preparations has been mainly restricted to the treatment of lung infections due to multidrug‐resistant (MDR) gram‐negative bacteria in patients with cystic fibrosis (6,7). The emergence of bacteria resistant to most classes of commercially available antibiotics and the shortage of novel antimicrobial agents with activity against gram‐negative microorganisms have led to the reemergence of polymyxins as a valuable addition to the therapeutic armamentarium. It was thus considered timely to review colistin and its emerging role in managing infections due to MDR gram‐negative bacteria.

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.
