Microbiologia do meato médio na rinossinusite crônica
Bibliographic record
Abstract
Este foi um estudo prospectivo que visou identificar a microbiologia do meato médio em pacientes com rinossinusite crônica (RSC) e compará-la com a de indivíduos sadios. MATERIAL E MÉTODOS: Foram incluídos 134 pacientes RSC e 50 voluntários sadios, que constituíram o grupo controle. As amostras foram coletadas endoscopicamente e submetidas a exames pelo método de Gram com contagem leucocitária e culturas para aeróbios, anaeróbios e fungos. RESULTADOS: Nos pacientes com RSC foram cultivados 220 microorganismos, dentre os quais os mais freqüentes foram o Staphylococcus aureus, presente em 31% das amostras, e o Staphylococcus coagulase-negativo (SCN) em 23%. Gram-negativos ou facultativos foram isolados em 37% das amostras, anaeróbios em 12%, e fungos em 14%. Ao exame bacterioscópico evidenciou-se alguns ou numerosos leucócitos em 74% das amostras com culturas positivas. Nos indivíduos sadios o SCN foi isolado em 40% das amostras e o Staphylococcus aureus em 18%. Em 12% dos indivíduos a cultura para fungos foi positiva, e o exame direto negativo. Todas as culturas anaeróbias foram estéreis. Quanto à contagem leucocitária todos apresentaram nenhum ou raros leucócitos. CONCLUSÃO: Os grupos apresentaram resultados semelhantes quanto à microbiologia, entretanto, diferiram em relação à contagem leucocitária, o que auxilia na diferenciação um microorganismo infectante de um colonizante.

How this classification was reachedexpand
Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
