Objective: Medical students experience high psychological demands that predispose them to stress, anxiety, and depression. This study aimed to determine the prevalence of stress, anxiety, and depression in 4th-year MBBS students and measure the efficacy of a short-term mindfulness-based life coaching (MBLC) intervention. Methods: This study consisted of a cross-sectional screening followed by a...
Background. Ketamine provides rapid but short-lived antidepressant effects for treatment-resistant depression (TRD). To prolong this response, ketamine-assisted therapy (KAT) combines the drug's pharmacological effects with psychotherapy. Aim. This study aims to analyze scientific evidence regarding the synergistic interaction between ketamine's pharmacological effects and modern...
Ketamine, a dissociative anesthetic introduced in the 1960s, has re-emerged as a versatile therapeutic agent extending beyond its traditional perioperative role. Its rapid antidepressant action in treatment-resistant depression and efficacy in acute and chronic pain syndromes have driven what is termed the “ketamine renaissance.” Unlike conventional monoaminergic antidepressants, ketamine...
Treatment resistance (TR) in major depressive disorder (MDD) affects a substantial minority of patients and is hard to recognize early, delaying intensified care. The Esketamine multi-omic biomarker evaluation in MDD (EMBER-MDD) is a non-interventional, investigator-initiated, in-vitro study within the EU Psych-STRATA programme, analyzing biospecimens collected in the randomized INTENSIFY study...
Major depressive disorder, or MDD, is a common cause of disability around the world. Treatment-resistant depression, or TRD, is a tough challenge. Many people do not respond well to treatment, which increases the risk of relapse and suicide. Esketamine is a new treatment that comes as a nasal spray. It works quickly and targets a specific brain receptor. This review looks at research from...

Major depressive disorder (MDD) is a heterogeneous, debilitating disorder. A distinct subgroup within the MDD spectrum is identified to have treatment-resistant depression (TRD). There is an impetus to find alternative treatments for TRD to reduce disease burden and improve quality of life. Psychedelics have been used in the treatment of various psychiatric disorders since the 1950s, with...
Psilocin (4-hydroxy-N, N-dimethyltryptamine) is a substituted tryptamine alkaloid and a nonselective serotonergic agonist acting predominantly at 5-HT2A/C receptors, with substantial binding to 5-HT1A and 5-HT2B receptors. Microdosing is the practice of taking a very small, sub-perceptual dose, typically 5% to 10% of a full recreational dose, to improve mood, creativity, and focus without...

Objective: To evaluate the effects of mindfulness-based stress reduction (MBSR) combined with standard perioperative care on perioperative outcomes in patients with advanced hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE). Methods: This retrospective study enrolled patients with advanced HCC who underwent TACE and received either standard perioperative care...
The mass evacuation of Israeli residents from conflict zones after the events of October 7, 2023, coupled with ongoing security threats, has taken a substantial psychological toll, with many individuals exhibiting symptoms of post-traumatic stress disorder (PTSD), anxiety, and sleep problems. This pilot study examined the feasibility and preliminary within-group changes associated with...
Major depressive disorder (MDD) ranks among the foremost contributors to disability worldwide, yet its neurophysiological mechanisms remain poorly understood. Excitation-inhibition (E/I) imbalance has been implicated in MDD pathophysiology, but cortex-wide E/I ratio and its molecular substrates in MDD remain unknown. Resting-state functional magnetic resonance imaging data from 254 MDD patients...
An individualized one‐day dosing regimen of a vaporized formulation of the psychedelic mebufotenin (5‐methoxy‐ N,N ‐dimethyltryptamine; 5‐MeO‐DMT) was more effective than placebo in improving depressive symptoms in adults with treatment‐resistant depression, a Phase 2b trial has found. No serious treatment‐emergent adverse events were reported during the 7‐day study. Results were published...
To explore the associations between mindfulness, psychological distress, and health-related quality of life (HRQOL), and examine whether psychological distress mediates the association between mindfulness and HRQOL in individuals with Parkinson's disease (PD). This is a secondary analysis of baseline data from a clinical trial investigating mindfulness-based interventions in patients with...
The U.S. Food and Drug Administration (FDA) has increasingly focused on breakthrough molecular mechanisms, rapidly acting medications, and expanded therapeutic indications in the treatment of depression. During this period, psychiatric interventions targeting N-methyl-D-aspartate (NMDA) receptors and intracellular signaling pathways have gained prominence, moving beyond the traditional...
Background/Objectives: University students commonly experience psychological distress driven by academic demands, social transitions, and financial pressures. Mindfulness-based interventions have emerged as scalable approaches to improve mental health. However, evidence comparing their effectiveness across delivery formats remains limited. This systematic review aimed to evaluate the...

Dextromethorphan-bupropion, a novel oral N-methyl-D-aspartate receptor antagonist approved by the Food and Drug Administration in August 2022, launched in the United States in October 2022 for major depressive disorder. We aimed to detect and characterize the adverse events (AEs) of dextromethorphan-bupropion using the FDA adverse event reporting system from the 4th quarter of 2022 to the 4th...
Abstract A central challenge in neuroscience is understanding how the human brain is organised to support optimal functioning and adaptability. One approach to characterise complex brain dynamics is by artificially perturbing whole-brain models. Here, we asked whether whole-brain organisation under perturbation in major depressive disorder (MDD) changes after intervention with psilocybin and...
Introduction: Treatment-resistant depression (TRD) is a major public health and societal challenge, associated with persistent symptoms, functional impairment, and increased healthcare and economic burden. Intranasal esketamine has emerged as a rapid-acting adjunctive therapy with a distinct glutamatergic mechanism of action. This systematic review summarizes current evidence on its...
Background: Intranasal esketamine (ESK-NS) is an effective treatment for treatment-resistant depression (TRD), but whether antidepressant outcomes differ by sex and age remains insufficiently explored. Methods: This secondary analysis of the REAL-ESK study included 210 patients with TRD treated with ESK-NS in routine clinical practice and assessed at baseline (T0), one month (T1), and three...
Oral S-ketamine (S-KETPO) is being explored as an alternative to intravenous maintenance treatment (S-KETIV) in treatment-resistant depression (TRD). However, the first-pass effect with S-KETPO significantly alters S-ketamine's bioavailability and the systemic exposure of its active metabolites, raising potential safety and efficacy concerns. This study characterized the pharmacodynamic and...
Depression and its severe outcomes, suicidal ideation and behavior, are exacerbated by stress. A broad literature links dysregulation of the hypothalamic-pituitary-adrenocortical (HPA) stress response system to depression, suicidal ideation and behavior. Our midazolam-controlled clinical trial of subanesthetic, intravenous ketamine infusion for suicidal depressed patients found rapid reduction...
