Abstract Background: The critical issue of treating Treatment-Resistant Depression (TRD) is to improve antidepressant effect rapid onset and the recovery rates. Significant antidepressant effects of ketamine onset rapidly, but decay rapidly and repeated dosing increases the risks. This study aimed to explore the efficacy and safety of single intravenous ketamine, combined with venlafaxines...

Abstract BackgroundKetamine has emerged as a rapid-acting antidepressant in treatment-resistant depression (TRD) increasingly used in non-research, clinical settings. Few studies, however, have examined neurocognitive effects of repeated racemic ketamine infusion treatments in patients with TRD. In an effort to identify potential effects after serial infusions, we conducted a retrospective...

Intravenous (IV) ketamine has been shown to have rapid antidepressant effects in individuals with treatment-resistant depression (TRD). This treatment protocol describes a clinical method for use of subcutaneous (SC) and intramuscular (IM) racemic ketamine in individuals with TRD, developed by a team at the University of British Columbia (UBC), UBC Hospital, and Vancouver General Hospital. The...

Abstract Background: Studies have confirmed the rapid antidepressant action of ketamine in depressive episodes. Nevertheless, a standardized procedure for the delivery of ketamine infusion in individuals suffering from treatment-resistant depression, particularly in terms of infusion frequency and total dosage, remains undetermined. In addition, an efficacious ketamine regimen for persistent...

Abstract Ketamine has rapid-onset antidepressant activity in patients with treatment-resistant major depression (TRD). The safety and tolerability of racemic ketamine may be improved if given orally, as an extended release tablet (R-107), compared with other routes of administration. In this phase 2 multicentre clinical trial, adult patients with TRD and Montgomery-Asberg Depression Rating...

Abstract Objective To observe the effects of esketamine on postoperative depression and pain indicators in individuals undergoing total laparoscopic hysterectomy. Methods 135 patients undegoing total laparoscopic hysterectomy were recruited and randomly allocated to three groups. Finally, a total of 127 patients were selected into the statistical analysis, with the final grouping information as...

Purpose: Depression combined with insomnia is a complex bidirectional relationship that is more difficult to treat versus a single disorder, and there is a lack of effective treatments available. In this study, we carried out a novel way to simultaneously intervene in depression combined with insomnia and examined functional magnetic resonance imaging (fMRI) to help further elucidate the...

Abstract Background Postpartum depression (PPD) after cesarean delivery is a common complication. Esketamine's effects on PPD in women undergoing cesarean section remain contradictory, despite ketamine's prophylactic effects. This study evaluated the effect of esketamine as an adjunct to patient-controlled intravenous analgesia (PCIA) to prevent PPD in women undergoing caesarean section....

Background: Borderline Personality Disorder (BPD) affects 1.35% of the population and is frequently comorbid with Major Depressive Disorder (MDD), which is frequently treatment-resistant (TRD). Patients with comorbid illness have worse treatment outcomes and functional impairment. Esketamine could ameliorate symptoms of both illnesses. Methods: We conducted a retrospective chart review of...

Background: Facial emotion recognition deficits are well defined in depression but understudied in treatment-resistant depression (TRD). Over the past decades, subanesthetic doses of ketamine have emerged as an effective treatment for TRD, but its effect on affective processing is still little known. Approaches from computational psychiatry, such as sequential evidence sampling models of...
