Ciprofol is a novel GABAergic intravenous anesthetic with a rapid onset and favorable safety profile; however, the neural mechanisms underlying the induction and reversal of unconsciousness remain unclear. Electroencephalogram (EEG) microstates provide millisecond-scale markers of large-scale brain network dynamics and may reveal frequency-specific signatures of ciprofol' s effects on...
Abstract Objective In this study, we comprehensively studied alternations of EEG microstates in resting state, light, and deep level of propofol-induced unconsciousness. We further investigated the feasibility of using microstate features for differentiating different consciousness levels. Methods 60-channel EEG was recorded from 31 male subjects in resting, light, and deep anesthesia states....
Importance: Controlled studies have shown short-term efficacy of esketamine for treatment-resistant depression (TRD), but long-term effects remain to be established. Objective: To assess the efficacy of esketamine nasal spray plus an oral antidepressant compared with an oral antidepressant plus placebo nasal spray in delaying relapse of depressive symptoms in patients with TRD in stable...
