Este trabajo muestra que la forma en que el corazón y la respiración se coordinan durante la noche, medida en casa, se diferencia en quienes después desarrollaron problemas. Eso abre la puerta a un control barato, aunque todavía falta confirmar que sirva para decidir tratamientos y que el hallazgo se repita en otras poblaciones.","quienFirma":"nuMoM2b Cohort (estudio multicéntrico en Estados Unidos; institución principal no determinada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"3cf7da2435a322972a29ce8bb835130238cd97be02196e4719be1b00096e955e","sello":"434a46cb445cdbeb00e7283da05b0e111f5a7876a67cfb898bca56a6099a8c7b","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6615358,"aleatorio":"dea34d9415fda039253ca8d94627f148121c8ca73b08d94a2520e75ae1d9a091","tiempo":"2026-11-05T15:16:00.000Z"},"nist":{"cadena":2,"pulso":2014613,"salida":"B69E990F5D06D664336B4EE605C03E319C46E61D7D270A83824B68FDADEA1B03BD725F7CA850D4350ADCEF7F9E3CF31651C3A1B4047F8901EA00045DF8B71FA7","tiempo":"2026-11-05T15:15:00.000Z"},"noAntes":"2026-11-05T15:16:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  5 15:16:20 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"First-trimester nocturnal cardiorespiratory coupling during home sleep testing and later pregnancy complications: a secondary analysis of the nuMoM2b cohort","descripcion":"We tested whether direction-specific nocturnal cardiorespiratory coupling (CRC) in the first trimester differed in pregnancies that later developed obstetric complications. The analysis included 2504 nulliparous women from the nuMoM2b cohort with valid level 3 home sleep recordings at 6-13 weeks' gestation. Bidirectional CRC between RR intervals and abdominal respiratory effort was quantified using bivariate phase-rectified signal averaging in consecutive 5-min segments. Coupling strength, local transition dynamics, and waveform irregularity were summarized by nightly mean and standard deviation.
