The review adhered to the PRISMA guidelines and was registered in PROSPERO (CRD42024512366). A comprehensive literature search was conducted in Google...
Ketamine has anesthetic, analgesic, and antidepressant properties which may involve multiple neuromodulatory systems. In humans, the opioid receptor (OR) antagonist naltrexone blocks the antidepressant effect of ketamine. This mechanism may differentiate ketamine from other NMDA receptor antagonists. Animal models that reflect OR-dependent behavioral effects of ketamine may shed light on the...
Recent studies in mouse models have demonstrated that ketamine and rapastinel induce rapid-acting and sustained antidepressant effects in major depressive disorder (MDD). However, it remains unclear how ketamine's and rapastinel's opposing mechanisms of action-NMDAR antagonist and NMDAR positive allosteric modulator, respectively-result in similar antidepressant-like effects. Furthermore,...
Ketamine has garnered attention for its rapid efficacy in alleviating depressive symptoms in treatment-resistant depression, offering a novel mechanism as a non-monoaminergic agent. Despite its potential, limited research has explored mental health professionals' perspectives on its use. This study assesses the attitudes, knowledge, and concerns of Portuguese psychiatrists and psychologists...
We previously reported that a single injection of (R,S)-ketamine or its metabolite (2S,6S)-hydroxynorketamine (HNK) prior to stress attenuated learned fear. However, whether these drugs attenuate learned fear through divergent or convergent effects on neural activity remains to be determined. 129S6/SvEv male mice were injected with saline, (R,S)-ketamine, or (2S,6S)-HNK 1 week before a 3-shock...
Ketamine, a dissociative anesthetic, has gained widespread use in various medical contexts, including anesthesia, pain management, and treatment-resistant depression. Despite its therapeutic potential, concerns regarding its safety profile have prompted ongoing research and regulatory guidance. This comprehensive literature review explores the current safety considerations of ketamine,...
Professional practice guidelines for the use of ketamine in psychiatric practice have been developed by the Royal Australian and New Zealand College of Psychiatrists to provide guidance on the use of ketamine in clinical practice in Australia and Aotearoa New Zealand, based on scientific evidence and supplemented by expert clinical consensus. Articles and information were sourced from existing...
The study aims to explore the relationship between mindfulness, rumination thinking, anxiety state, and depressed mood, and the chain mediating roles of rumination thinking and anxiety state in explaining how mindfulness influences depressed mood in infertile women. This cross-sectional study included 946 women with infertility from a maternal and child hospital in western China through...
Psychological and existential distress is prevalent among patients with life-threatening cancer, significantly impacting their quality of life. Psilocybin-assisted therapy has shown promise in alleviating these symptoms. This systematic review aims to synthesize the evidence on the efficacy and safety of psilocybin in reducing cancer-related distress. We searched MEDLINE, APA PsycINFO, Cochrane...
Mindfulness-based interventions have been shown to improve the quality of life of cancer patients and are widely recommended. This was a non-randomized, single-center study designed to assess the feasibility and benefits of a mindfulness and compassion program for individuals living with cancer (MCP-C). The primary objective was to evaluate the feasibility of the program, while the secondary...
