Aim The present study aimed to examine whether heart rate variability (HRV) indices in depressed patients measured at return to work after sick leave are related to the outcome of reinstatement. Methods This study included 30 workers who took a leave of absence due to major depressive disorder. HRV was measured twice, once when participants left work and another when they returned to work. One month after returning to work, 19 participants continued their original work (successful return group), while 11 failed to perform their original work (unsuccessful return group). HRV indices including high‐ and low‐frequency components (HF and LF) were calculated in three conditions within a session lasting for about 5 minutes, initial rest (Rest), mental task (Task), and rest after task (After), and were compared between the two participant groups. Psychological states were evaluated using Self‐rating Depression Scale and State‐Trait Anxiety Inventory. Results No significant differences were observed in the HRV indices on leaving work between groups. On returning to work, the “unsuccessful return group” exhibited lower HF Rest score, higher HF Task/Rest ratio, and higher LF/HF Rest score than the “successful return group.” Psychological scores improved in both groups. Conclusion These results indicate that autonomic dysregulations revealed by HRV measurement at return to work after a leave of absence in MDD patients were related to the outcome of reinstatement and can serve as useful information for the assessment of the risk of unsuccessful return.

P Pu ur rp po os se e: : To assess the effects of age on recovery of psychomotor function for propofol sedation during spinal anesthesia.M Me et th ho od ds s: : Propofol was continuously infused during surgery and spinal anesthesia in 15 elderly patients (65-85 yr-old) and 15 younger patients (20-50 yr-old). Infusion rates were adjusted to maintain an appropriate level of sedation using the bispectral index (range 60-70). The sedative infusion was discontinued at the end of surgery. The early recovery times from the end of propofol infusion to opening of eyes on command, sustaining a hand grip, and recall of name were noted. Psychomotor function, as measured by the Trieger's dot test, was evaluated before anesthesia and 30, 60, 90, 120 min after the end of propofol infusion.R Re es su ul lt ts s: : The duration of anesthesia was 142 ± 55 min and 134 ± 61 min in the elderly and younger patients, respectively. No differences were observed in early recovery times between elderly and younger patients (opened their eyes on command, 6.3 ± 4.0 min and 5.2 ± 2.6 min; sustained a hand grip, 7.2 ± 3.9 min and 6.1 ± 3.5 min and recalled their name, 8.0 ± 4.5 min and 6.5 ± 3.8 min, P > 0.05 ). The recovery of psychomotor function in the elderly took longer compared with the younger patients, and psychomotor function in the elderly recovered at 120 min after the end of propofol infusion.C Co on nc cl lu us si io on n: : Early recovery times following propofol sedation is similar between elderly and younger patients, but recovery of psychomotor function in the elderly is delayed compared with younger patients. Objectif Résultats : La durée de l'anesthésie a été de 142 ± 55 min et de 134 ± 61 min chez les patients âgés et les plus jeunes, respectivement. Aucune différence des temps de récupération précoce n'a été observée entre les patients âgés et les autres (l'ouverture des yeux surcommande : 6,3 ± 4,0 min et 5,2 ± 2,6 min ; la préhension de la main : 7,2 ± 3,9 min et 6,1 ± 3,5 min et la capacité de se nommer : 8.0 ± 4,5 min et 6,5 ± 3,8 min, P > 0,05 ). Le rétablisse-ment de la fonction psychomotrice a été plus long chez les gens âgés comparés aux plus jeunes et s'est produit à 120 min après la fin de la perfusion de propofol chez les patients âgés. Conclusion : Les temps de récupération précoce qui suit la sédation au propofol sont similaires chez les patients âgés ou plus jeunes, mais le rétablissement de la fonction psychomotrice est retardé chez les patients âgés comparés à des patients plus jeunes.GE is one of the many factors known to influence recovery following anesthesia. [1][2][3][4][5] Propofol is commonly used to provide sedation during spinal anesthesia because of its high clearance rate and short elimination halflife.6-9 However, there have, so far, been few reports on the recovery of psychomotor function after propofol sedation in the elderly. The purpose of this study is to clarify the influence of age on the recovery of psy-
