Acute (R,S)-ketamine (ketamine) administration produces rapid antidepressant effects that in some patients can be sustained for several days to more than week. Ketamine blocks NMDA receptors to elicit specific downstream signaling that induces a novel form of synaptic plasticity in the hippocampus that has been linked to the rapid antidepressant action. These signaling events lead to subsequent...

BACKGROUND Whether cortical excitation and inhibition functions differ between patients with treatment-resistant depression (TRD) and strong suicidal ideation (SI) and healthy subjects and whether 0.5 mg/kg ketamine infusion can modulate cortical excitation and inhibition functions among patients with TRD-SI remain unclear. METHODS A total of 29 patients with TRD-SI and 35 age- and sex-matched...

Ketamine has been described as a fast‐acting antidepressant, exerting effects in depressed patients and in preclinical models with a rapid onset of action. The typical antidepressant fluoxetine is known to induce plasticity in the adult rodent visual cortex, as assessed by a shift in ocular dominance, a classical model of brain plasticity, and a similar effect has been described for ketamine...

Background: To evaluate the effect of pre-administration of esketamine intraoperatively on the occurrence of postpartum depression after cesarean section under combined spinal-epidural anesthesia. Methods: A total of 120 women aged 24 to 36 years undergoing cesarean section by spinal-epidural anesthesia with American Society of Anesthesiologists physical status II were enrolled. According to...

Treatment-resistant depression (TRD) is a challenge for psychiatrists, even after more than seven decades since the first antidepressants were used in clinical practice. Non-monoaminergic-based drugs with antidepressant properties have been developed, but to date, only esketamine and brexanolone have been approved for TRD and postpartum depression, respectively. A narrative review on the...

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...
