Abstract

fetched live from OpenAlex

La historia del tratamiento de la encefalopatía hipóxica isquémica (EHI) con hipotermia en animales de experimentación se remonta a la decada de los 90.Con buenos fundamentos fisiopatológicos, estos estudios mostraron los beneficios del tratamiento [1][2][3][4][5][6][7][8] .A partir de estos resultados, se realizaron numerosos estudios aleatorizados en recién nacidos a término y pretérmino tardío.Once de estos estudios se revisaron en la Biblioteca Cochrane y se encontraron más de 1500 casos en los que, tanto estadística como clínicamente, la mortalidad fue menor y el desarrollo psicomotor fue superior a los 18 meses de edad posconcepcional en los pacientes que fueron tratados con hipotermia terapéutica 9 .Un metaanálisis más reciente (2020) evaluó la mortalidad de recién nacidos con EHI en 28 estudios aleatorizados: 1832 pacientes recibieron tratamiento con hipotermia y 1760 no lo recibieron.El riesgo relativo (RR) de mortalidad en este metaanálisis fue de 0.74 (intervalo de confianza del 95% [IC95%]: 0.67,0.80).Los autores realizaron un análisis por subgrupos con respecto al tipo de ingreso de los países, y el riesgo relativo de mortalidad en países de bajos, bajos-medios, altos-medios y altos ingresos fue de 0.32 (IC95%: -0.95,1.60),0.5 (IC95%: 0.14,0.86),0.62 (IC95%: 0.41,0.83)y 0.76 (IC95%: 0.69,0.83),respectivamente 10 .

Not 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.
