This network meta-analysis evaluated the efficacy and safety of the dextromethorphan-bupropion combination (AXS-05) in treating major depressive disorder (MDD). Data were retrieved from multiple databases, including PubMed, Embase, Scopus, Google Scholar, and ClinicalKey, yielding 60 records. After removing duplicates and excluding irrelevant studies, such as reviews, case reports, posters, and...
Nitrous oxide ("laughing gas") is an NMDA receptor antagonist. In the current study, our aim was to investigate the efficacy, safety, and likely optimal dose of nitrous oxide in adults with major depressive disorder (MDD). In this phase 2b randomized, double-blind trial, 81 patients with MDD were allocated on a 1:1 basis to receive nitrous oxide or oxygen/air (control); the nitrous group was...
The novel antidepressant ketamine has been shown to achieve what most classic antidepressants, such as Selective Serotonin Reuptake Inhibitors, have not been able to. A rapid onset of symptomatic improvement across multiple domains; mood, anhedonia, and suicidal ideation. The exact neuropsychopharmacological mechanisms of this unique phenomenon are still unknown, although many theories are...
The following part of the abstract had a minor error: ‘Following PT, there was greater activation in the ventromedial prefrontal cortex and sensory regions, and reduced activation in the angular gyrus.’ This is now corrected to ‘Following PT, there was decreased activation in the ventromedial prefrontal cortex and angular gyrus, and greater activation in sensory regions.’ The original article...
Menopause is associated with significant physical, psychosocial, and emotional changes that can negatively affect women's quality of life (QoL). In response to this, psychological interventions like mindfulness-based interventions have shown promise in alleviating menopausal symptoms and improving psychological well-being. A comprehensive randomized controlled trial was conducted from May to...
Mindfulness-based interventions may contribute to the mental health status and well-being of nurses. Current results are inconsistent, and there are no systematic review and meta-analyses for intensive care unit (ICU) nurses. The aim of this study was to assess the effectiveness of mindfulness-based interventions on psychosocial well-being and occupational-related outcomes among nurses in the...
Background: Psilocybin-assisted psychotherapy (PAP) is a promising treatment for various psychiatric disorders. However, the exact biological and psychological mechanisms of action of PAP remain to be determined. Examining predictors of PAP outcomes may help identify necessary processes for positive treatment outcomes. Mystical experiences are considered a key aspect of the subjective effects...
Intranasal esketamine (ESK) is a novel therapy option in patients with treatment-resistant depression (TRD). Patients with a history of electroconvulsive therapy (ECT) non-response (ECT+) in the current episode have usually been excluded from previous studies. Data on the effectiveness of ESK in ECT non-responders are sparse. In this retrospective study, we investigated the effectiveness of...
Treatment-resistant depression is one of the most significant clinical challenges in psychiatric practice. The primary aim of the present study was to assess the efficacy and tolerability of intranasal esketamine on depressive symptoms in a real-world outpatient setting. A secondary objective was to explore the potential benefits of intranasal esketamine on hopelessness and suicide risk...
Recent evidence suggests that the rapid-acting antidepressant ketamine has immune regulatory functions. The complement system is an important component of the innate immune response and plays a key role in synaptic plasticity. An increase in complement component 3 (C3) expression was previously found in the prefrontal cortex of individuals with depression. Given the complement system's role in...
Ketamine is a rapid-acting antidepressant with sexually dimorphic effects. Female animals exhibit a higher sensitivity to its antidepressant properties, which has been associated with their ovarian hormone levels. One factor contributing to this sex difference is the faster rate of ketamine metabolism observed in females, potentially regulated by estrogen receptor alpha (ERα) through modulation...
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...
Treatment-resistant depression (TRD) is associated with reduced quality of life and elevated mortality, posing a major challenge to psychiatric care. After non-response to conventional treatments, next-level interventions such as (es)ketamine are recommended, though remission rates remain variable. Identifying reliable markers of treatment response is therefore critical. Recent evidence...
Treatment-resistant depression (TRD) remains a challenge, but intravenous racemic ketamine offers rapid antidepressant effects. Reliable biomarkers are needed. In this study, we examined kynurenine pathway metabolites and inflammatory cytokines as predictors of ketamine response. The Bio-K study was a multicenter, open-label trial of 74 patients with TRD who received 3 ketamine infusions over...
Consistent dream sequences that appear genuine and become more upsetting as they progress are known as nightmares. A prevalent condition that significantly impairs psychosocial performance and lowers quality of life is major depression. Insomnia and nightmares independently but additionally have an impact on the exacerbation of depression. Objectives: To find the correlation between depression...
Depressive disorder is one of the most prevalent mental health problems with a significant impact on quality of life. In Indonesia, the 2018 National Health Survey (Riskesdas) reported a prevalence of depression among adolescents at 6.2%, with risk increasing along with age. The high relapse rate makes depression a chronic condition that requires long-term intervention strategies....
This systematic review and meta-analysis evaluates (1) the effectiveness of psychedelic-assisted therapy (PAT) using psilocybin and ketamine for psychosocial symptoms in adults with cancer, (2) contextualizes findings with non-randomized and exploratory studies of other psychedelics, and (3) examines the role of therapeutic frameworks in shaping outcomes. We searched PubMed, Cochrane Library,...
Ketamine has emerged as a putative rapid-acting treatment option for psychiatric disorders, particularly treatment-resistant depression. Chronic recreational ketamine use is associated with ketamine-induced urological toxicity, raising concerns over the safety of repeated ketamine treatments. This systematic review aimed to synthesise urological findings from clinical trials and observational...
Ketamine's potential as a rapid-acting antidepressant was first identified in 2000, despite its long-standing use as an anesthetic agent. Clinically, ketamine alleviates depressive symptoms, including the difficult to treat symptom of anhedonia, within hours, with the effects of a single dose lasting for days. Since then, research has focused on uncovering the mechanisms underlying its rapid...
While traditional mindfulness-based interventions demonstrate effectiveness in improving mental health outcomes, their delivery methods face significant challenges related to accessibility and engagement. Geographic barriers to trained facilitators, time constraints for in-person sessions, and participant dropout rates of 15% to 30% due to perceived monotony limit intervention reach and...
