Postpartum depression (PPD) affects 10-20% of women after childbirth, with incidence reaching 30-50% in high-risk populations. Acute postoperative pain and sleep disturbance represent modifiable risk factors. This study evaluated whether a multimodal analgesic protocol combining dexmedetomidine and esketamine is associated with reduced PPD incidence in high-risk parturients undergoing cesarean...
Ketamine is a dissociative anesthetic with potential for treating mood, anxiety, and related disorders; however, concerns have emerged regarding hepatotoxicity in the context of chronic treatment. Systematic searches of PubMed, Scopus, and Ovid databases were conducted from inception to August 2025. Eligible studies included randomized controlled trials (RCTs), observational studies, and case...

Psychedelic-assisted therapy offers rapid and profound benefits for treatment-resistant psychiatric conditions but remains constrained by the need for intensive, clinic-based administration. Concurrently, advances in digital health technologies have introduced scalable tools. This systematic review evaluates the safety, efficacy, and implementation of digitally enabled psychedelic-assisted...

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...
Ketamine， a non-competitive N-methyl-D-aspartate （NMDA） receptor antagonist， has gained increasing attention for its rapid antidepressant effects in treatment-resistant depression （TRD） and suicidal ideation. Its mechanisms include NMDA receptor blockade， AMPA receptor activation， and upregulation of BDNF/mTOR signaling. Its enantiomers， esketamine and R-ketamine， as well as its metabolites，...
Ketamine has been widely used since its discovery, and in addition to its anesthetic effects, in recent years it has been found to exhibit rapid and sustained antidepressant effects in rodent models and in patients with treatment-resistant depression (TRD) at subanesthetic doses. The antidepressant mechanism of ketamine has also been intensively studied, involving glutamate receptors such as...

Interventional psychiatric procedures (IPPs) such as electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and ketamine intravenous treatments (KIT) are widely used for treatment resistant depression (TRD), but we lack studies of their real-world impact compared to standard outpatient medication management (MM). Longitudinal electronic health records of 22,481 patients in a...
Postoperative delirium and other forms of perioperative neurocognitive deficits occur commonly in older adult patients. Ketamine, administered either before or during general anaesthesia, may have cognitive-sparing properties owing to its ability to reduce neuroinflammation, increase neurotrophin levels, or allow reductions in the doses of other general anaesthetic drugs. However, the efficacy...
Treatment-resistant depression (TRD) presents substantial clinical challenges, particularly in patients with Alzheimer's disease (AD) and older adults experiencing late-life depression. Traditional monoaminergic therapies often fail in this population due to neurodegenerative changes that impact receptor dynamics and neurotransmitter systems. Emerging evidence suggests that N-methyl-D-aspartate...
Assessment measures for suicidal behavior range from depression scales to longer suicide-specific instruments. In this review, we systematically summarize and discuss the currently used instruments for assessing suicidal behavior in the context of ketamine and its enantiomers. We searched Medline/PubMed, Embase, and PsycINFO databases for ketamine (and its enantiomers) human studies exploring...
