Medicamentos na gravidez e na lactação: novas normas da FDA
Bibliographic record
Abstract
New rules set forth by the Food and Drug Administration (FDA) for the use of drugs during pregnancy and lactation take effect this year (2015). They reshape the content and format of labeling and concomitantly remove any reference to the A, B, C, D,and X categories. The latter are replaced by a summary of the perinatal risks associated with the drug, discussion of related evidence, and a summary of the most relevant data for prescription decision-making. Also, the new rules include essential information on the identificati on of pregnancy, contraception, and infertility. The ultimate goal of the new rules is to facilitate the process of prescribing drugs by offering consistent, well-structuredinformation about the use of drugs during pregnancy and lactation.

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.
