Contribution to the study of Plasmodium falciparum resistance to atovaquone-proguanil
Bibliographic record
Abstract
Depuis 2000, l'atovaquone-proguanil (AP) est utilisée dans le traitement des accès simples à Plasmodium falciparum. Au cours de ce doctorat, la sensibilité in vitro à l'atovaquone de 477 isolats africains a été évalué à 1,79 +- 1,3nM. L'association s'est avérée efficace pour le traitement de 459 patients. Les échecs observés montrent que les échecs précoces (0,9%) sont liés à une malabsorption des principes actifs alors que les échecs tardifs (<0,1%) sont liés, au moment de la rechute, à des parasites hautement résistants in vitro (CI50>8000nM) présentant une mutation au niveau du gène du cytochrome b (Y268S ou Y268C), sans amplification associée de ce gène. L'analyse du génome mitochondrial des parasites isolés avant et après l'échec confirme le faible taux de polymorphisme de ce génome et révèle des origines multiples et indépendantes des parasites mutants. L'émergence de parasites résistants à l'AP est fréquente mais le risque actuel de sa dispersion est négligeable.

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.
