Abstract

fetched live from OpenAlex

El déficit de vitamina D durante el embarazo tiene un impacto negativo en la salud materno-infantil. Objetivo: Evaluar el efecto del estado de vitamina D durante el embarazo sobre el neurodesa- rrollo del niño. Selección de estudios: Se realizó una búsqueda de la litera- tura científica publicada en PubMed/MEDLINE, Scopus y Cochrane has- ta enero del 2018. Se seleccionaron los estudios que relacionaban el estado de la vitamina D durante el embarazo con algún dominio del neurodesa- rrollo del niño (mental, motor, lenguaje, cociente intelectual y comporta- miento). La calidad de los estudios incluidos se evaluó a través de la escala Newcastle-Ottawa. Resultados: De los 164 estudios encontrados en la bús- queda, once estudios cumplieron los criterios y fueron considerados diez de alta calidad metodológica y uno de moderada. La revisión sistemática mostró que niveles prenatales de vitamina D <50 nmol/L se asocian fre- cuentemente a un peor desarrollo mental, motor y del lenguaje de sus hijos en comparación con las madres con concentraciones ≥50 nmol/L. Conclu- sión: Aunque existe poca evidencia científica que corrobore la relación entre la deficiencia de vitamina D prenatal y su impacto en el neurodesarrollo de los hijos, los datos actuales sugieren un perjuicio sobre el desarrollo mental, motor y del lenguaje del niño.

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.
