Catheter-Related Leuconostoc Bacteraemia in a Pregnant HIV-Infected Woman
Bibliographic record
Abstract
Leuconostoc species are Gram-positive coccobacilli that are members of the family of streptococcaceae . They are rarely encountered in clinical medicine and in the past were considered culture contaminants. More recently they have been recognized as a potential pathogen causing opportunistic infections. Unlike other Gram-positive cocci Leuconostoc spp. are intrinsically resistant to vancomycin. Here we present a case of fever and Leuconostoc spp. bacteraemia in a pregnant HIV-infected woman requiring parenteral nutrition via central venous access for severe hyperemesis gravidarum. The infection was successfully treated with catheter removal. To our knowledge this is the first report of bacteremia with this organism in pregnancy as well as in an adult HIV infected patient. Issues of possible misidentification of this organism as alpha-hemolytic streptococcus are discussed. J Med Cases. 2012;3(6):331-333 doi: https://doi.org/10.4021/jmc822w

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.
