Background: ECT is considered the fastest and most effective treatment for TRD. Ketamine seems to be an attractive alternative due to its rapid-onset antidepressant effects and impact on suicidal thoughts. This study aimed to compare efficacy and tolerability of ECT and ketamine for different depression outcomes (PROSPERO/CRD42022349220). Methods: We searched MEDLINE, Web of Science, Embase,...

IntroductionHealthcare practitioners (HCPs) are facing a mental health crisis. Group therapies have long been used to treat symptoms associated with PTSD, anxiety and/or depression, however no studies have investigated the role of implementing group therapy with and without ketamine-assisted therapies (KaT).ObjectivesThe current study investigated the effects of the Roots to Thrive (RTT) group...

IntroductionKetamine has been increasingly used to treat mental health conditions yet there is a lack of safety data on intramuscular (IM) and sublingual (SL) dosing in a community setting. The Roots to Thrive Ketamine assisted Therapy (RTT-KaT) program is a 12-week program with 12 Community of Practice (CoP) group therapy sessions and three ketamine sessions.ObjectivesTo provide preliminary...

Background: Patients with missed miscarriages are usually accompanied by varying degrees of depression, which is closely related to the patient's prognosis. We investigated whether Esketamine could alleviate postoperative depression symptoms in patients with missed miscarriages who underwent painless curettage. Methods: This study was a randomized, parallel-controlled, double-blind,...

Ketamine therapies can offer rapid relief of depression and an antisuicidal effect, making them of particular interest for adolescents with treatment-resistant depression. In 1 randomized, double-blind study of adolescents with severe major depression, ketamine had a strong effect size for reducing depressive symptoms 24 hours after infusion. Currently, there is minimal investigation and few...

Abstract Background Preclinical evidence indicates that the κ-opioid receptor (KOR)/dynorphin pathway is implicated in depressive-like behaviors. Ketamine is believed to partly exert its antidepressant effects by modulating the opioid system. This post hoc study examined the following research questions: (1) at baseline, were there differences in KOR or dynorphin plasma levels between...

Working memory (WM) is a crucial resource for temporary memory storage and the guiding of ongoing behavior. N-methyl-D-aspartate glutamate receptors (NMDARs) are thought to support the neural underpinnings of WM. Ketamine is an NMDAR antagonist that has cognitive and behavioral effects at subanesthetic doses. To shed light on subanesthetic ketamine effects on brain function, we employed a...

Acute injections of ketamine lead to rapid but transient antidepressant effects. Chronic oral treatment at low doses, a promising non-invasive alternative, may prolong this therapeutic effect. Here, we examine the antidepressant effects of chronic oral ketamine in rats under chronic unpredictable mild stress (CUMS), and reveal their neuronal correlates. Male Wistar rats were divided into...

BACKGROUND: Alcohol use disorder is prevalent globally and in Kenya, and is associated with significant health and socio-economic consequences. Despite this, available pharmacological treatment options are limited. Recent evidence indicates that intravenous (IV) ketamine can be beneficial for the treatment of alcohol use disorder, but is yet to be approved for this indication. Further, little...

Abstract Ketamine shows rapid antidepressant effects peaking 24 h after administration. The antidepressant effects may occur through changes in glutamatergic metabolite levels and resting-state functional connectivity (rsFC) within the default mode network (DMN). A multistage drug effect of ketamine has been suggested, inducing acute effects on dysfunctional network configuration and delayed...
