Nebulized levofloxacin for chronic Burkholderia cenocepacia pulmonary infection in cystic fibrosis: A case report
Bibliographic record
Abstract
We present a patient with cystic fibrosis who used nebulized levofloxacin off-label to suppress chronic Burkholderia cenocepacia pulmonary infection. The patient was initially using tobramycin inhalation powder (TIP) off-label continuously for suppression of chronic B. cenocepacia; this was changed to alternating months of nebulized levofloxacin and TIP. Following initiation of nebulized levofloxacin, the patient had significant improvement in respiratory symptom burden and lung function (as measured by forced expiratory volume in 1 second [FEV1]), and a decrease in the frequency of pulmonary exacerbations. Further research is necessary to determine whether the benefits observed with nebulized levofloxacin in our patient translate to a larger population of patients with chronic Burkholderia spp. pulmonary infection.

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.
