Chronic stress precipitates depression, yet how gut-immune-brain interactions translate stress into mood pathology remains unclear. We tested the hypothesis that stress-primed small intestinal γδ T cells drive hippocampal mitochondrial dysfunction and depression-like behavior via interleukin-17A (IL-1A). In mice exposed to chronic restraint stress (CRS), we combined behavioral assays...

Objective: To compare acceptability and effectiveness of psilocybin, ketamine and commonly prescribed antidepressants in the management of Major Depressive Disorder (MDD). Methods: This is a systematic review with network meta-analysis. The survey was conducted between January and June 2023, employing MEDLINE, PsyINFO, Embase, Web of Science and ClinicalTrials.gov databases. Randomized...

There is a complex, bidirectional interaction between the gut microbiota and the central nervous system, known as the gut-brain axis. Esketamine, as the right-handed isomer of ketamine, has been approved by the US FDA for the treatment of treatment-resistant depression (TRD), and its rapid antidepressant effect may involve modulation of gut microbiota. In addition, other ketamine isomers (such...

Individuals with eating disorders (EDs) have an increased risk of treatment resistant depression (TRD) and treatment resistant bipolar disorder (TRBD) and a higher rate of suicidal ideation and death by suicide than individuals without EDs. Individuals with EDs are less responsive to conventional treatments for mood disorders than individuals without EDs. Ketamine has evidence for treatment of...

Treatment-resistant depression (TRD) poses significant clinical challenges, often necessitating alternative treatments such as intravenous (IV) ketamine or intranasal esketamine. This study compared the effectiveness of these modalities and examined predictors of treatment response, including comorbidity profile, prior antidepressant failures, age, and gender. A retrospective chart review was...

ABSTRACT: Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist that has been approved for use as a clinical and veterinary anesthetic since 1970. Although esketamine, a specific molecular form of ketamine, is FDA-approved for the management of treatment-resistant depression, regular ketamine is often used off-label at subanesthetic doses to treat depression as well as other...

Major depressive disorder (MDD) affects approximately 332 million people worldwide. Among those diagnosed with MDD, approximately 53% receive pharmacologic treatment, such as ketamine. Nurses must be knowledgeable about ketamine and other emerging, effective behavioral health therapies used to treat chronically depressed mood and acute suicidal ideation. This article outlines the best nursing...

Repetitive transcranial magnetic stimulation (rTMS) and intranasal esketamine are effective treatment options for treatment-resistant depression (TRD) that have not been directly compared. We aimed to compare the effectiveness of rTMS, intranasal esketamine, and pharmacotherapy for TRD using data from two randomised clinical trials (RCTs). This secondary analysis of individual patient data...

To assess the impact of low-dose intravenous esketamine on postpartum depression scores in women undergoing cesarean section. In a randomized, double-blind, placebo-controlled trial, 186 women aged 20-50 years receiving epidural anesthesia for cesarean section were divided into three groups: Group A (0.25 mg/kg esketamine intraoperatively + esketamine in PCIA), Group B (0.25 mg/kg esketamine...
