El estudio es retrospectivo y observacional, así que muestra asociación y no prueba que corregir el azúcar evite el delirio.","quienFirma":"Hospitales de China (estudio multicéntrico, 20 centros; institución coordinadora no identificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"f1405e2a8c4c8b261039428fe0aa9f2e68a3bccfa41e3f65ce3db4dffae6be13","sello":"5058e8edabb74206957614be3e255e550edaae1ff1930b33b6eacfc6e8893cc7","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575851,"aleatorio":"29e6764b49393fcb685b41ab04eb6667b179de6b518c8212d4aa11d1de9d1b19","tiempo":"2026-10-22T22:02:30.000Z"},"nist":{"cadena":2,"pulso":1995125,"salida":"70391569C3CDB488E71ABC660C5481B4A24B300E2E08E833696854B6488DAB0370809D6AA479035A0F6218DCEDD92C536F46C33AF62EF2BFF2B7635A2FD7E526","tiempo":"2026-10-22T22:02:00.000Z"},"noAntes":"2026-10-22T22:02:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 22:02:55 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"U-Shaped Association Between Preoperative Fasting Blood Glucose and Postoperative Delirium in Elderly Diabetic Patients: A Multicentre Retrospective Cohort Study","descripcion":"Abstract Objective: The heightened susceptibility of the aging brain to dysglycemia establishes blood glucose as a pivotal risk factor for postoperative delirium (POD) in elderly diabetic patients. This study investigated the association between preoperative fasting blood glucose (FBG) and POD risk in this population to define the optimal FBG range for POD. Methods: This study included 2,157 elderly diabetic patients undergoing non-cardiac surgery between April 2020 and April 2022 in 20 hospitals across China. The POD incidence was prospectively assessed using the 3-minute Diagnostic Interview for Confusion Assessment Method (3D-CAM) within 7 postoperative days.
