Treatment-resistant depression (TRD) is associated with immune dysregulation. Ketamine, a rapid-acting antidepressant, may exert effects via immunomodulation. The aim was to examine ketamine’s impact on immune markers in TRD, including T-cell subsets, cytokines, and in vitro T-cell responses. Eighteen TRD inpatients received 0.5 mg/kg iv ketamine. Blood was sampled at baseline, 4 h, and 24 h to...
Despite growing evidence supporting the efficacy of LSD-assisted psychotherapy in treating major depressive disorder (MDD), identifying reliable psychopharmacological biomarkers remains necessary. Oxytocin, a neuropeptide implicated in social bonding and flexibility, is a promising candidate due to its release following serotonergic psychedelic administration in healthy individuals; however,...
Mystical experiences are powerful experiences that may have therapeutic value. Ketamine, a dissociative anesthetic, has shown potential to induce mystical experiences. However, little research has explored this phenomenon, particularly in treatment-resistant depression. We analyzed clinical data from 60 veterans with treatment-resistant depression receiving a total of 189 ketamine treatments....

The stresses of the Coronavirus Disease of 2019 (COVID-19) pandemic highlighted the burden of psychiatric disorders within the pediatric population, revealing a pre-existing need for rapid-onset therapies that have since driven efforts to expand effective therapeutic interventions. In this narrative review, we utilized the Preferred Reporting Items for Systematic reviews and Meta-Analysis...
Abstract Background Only 18-45% of individuals with treatment-resistant depression (TRD) respond to intravenous ketamine therapy. Although some neurobiological predictors of response to ketamine have been reported, none have been consistently replicated across multiple studies. The imbalance between glutamatergic excitatory and GABAergic inhibitory neurotransmissions is implicated in the...
Abstract Background Depressive disorders affect about 280 million people worldwide, with many struggling to find effective relief. Conventional antidepressants are widely prescribed but often lack efficacy and have side effects, leaving many patients dissatisfied or untreated. Concurrently, psychedelic therapies have gained momentum in both research and ‘in the wild’, with emerging evidence...
Abstract Background Among the innovative treatments investigated for depression, psilocybin appears to play an extremely promising role, with several studies showing remission rates up to 70% in patients with treatment-resistant depression (TRD) treated with protocols involving a single or double dose administration [1,2]. Psilocybin is a psychedelic compound belonging to the tryptamine class,...
Abstract Background Depressive disorders are a major global health challenge, with many individuals unresponsive to existing treatments or left with residual symptoms such as impairments in cognition and social functioning. Emerging psychedelic therapies show promise for treating depression but require further research. Aims & Objectives This pilot study aimed to evaluate the feasibility,...
The gestational period is a sensitive time marked by significant changes that can affect women's sleep and dreaming processes, with an augmented frequency and recall of dreams suggesting that dreaming represents an adaptive mechanism of emotional regulation. This study investigates the relationship between pregnancy-related variables, alexithymia, and depressive symptoms in influencing dream...
Postpartum depression is a significant global public health issue, with serious maternal and neonatal consequences. Online mindfulness interventions provide a promising alternative, offering flexible and low-risk support that overcomes barriers like stigma and accessibility. This review aimed to assess the effects of online mindfulness interventions on postpartum depression, anxiety, and stress...
The rapid and clinically meaningful antidepressant effects of ketamine and esketamine are well-established in major depressive disorder (MDD) and treatment-resistant depression (TRD) as evidenced by improvement in clinician- and patient-reported depression measures. However, there remains a need to determine how these agents affect patient-reported quality of life (QoL). Herein, we aimed to...
Eating disorders are among the most challenging and fatal mental illnesses and, due to the complication of medical instability caused by malnutrition or other disordered eating behaviors, pose unique treatment challenges for patients with co-occurring depression and mood disorders. Randomized control trials have demonstrated "rapid and robust antidepressant effects" of generic ketamine in...

Treatment-resistant depression (TRD) remains a challenge in psychiatry, necessitating novel therapeutic strategies beyond traditional monoaminergic antidepressants. Ketamine and its S-enantiomer esketamine have demonstrated rapid and robust antidepressant effects in TRD, probably through mechanisms involving glutamatergic modulation, neuroplasticity, and anti-inflammatory properties. However,...
This single-case study aims to examine the effectiveness of an integrated mindfulness-based intervention in reducing symptoms of emotional numbness in major depressive disorder. A 30 year old female participant with severe depression (BDI-II = 29) received 12 individual sessions combining mindfulness-based cognitive therapy, body-centered mindfulness, and compassion-focused therapy at a private...
Provided herein are novel non-hallucinogenic neurite growth compounds as 5-HT2A agonists, pharmaceutical compositions, use of such compounds in treating stress-related disorders, namely depression, anxiety, and post-traumatic stress disorder (PTSD), and processes for preparing such compounds.
Objective: This study examines the durability (defined as time between treatments) of intravenous ketamine (IV-KET) and intranasal esketamine (IN-ESKET) for treatment-resistant depression (TRD), in a real-world clinical setting with repeated ketamine/esketamine maintenance therapy. Methods: This was a single-center, observational study of adults with TRD who completed acute-phase treatment...

Depression, a common mental disorder, affects people at different stages of life.Classic antidepressant treatment is generally effective, however, it is prolonged.Nonetheless, numerous patients who undergo various classic antidepressant therapies still suffer from depression.Therefore, the search for novel medications is essential.In this review, we explore the therapeutic potential of...
Importance Psilocybin has demonstrated rapid and sustained antidepressant efficacy, with acute-phase effect sizes often more than double those for conventional antidepressants. However, concerns have been raised that high rates of functional unblinding in combination with trial participants with positive expectations of psychedelic use might bias treatment outcomes. Objective To compare...

Intensive care units (ICUs) are high-risk, high-stress environments that substantially increase the likelihood of nursing staff becoming second victims (SVs). However, current research on mindfulness interventions for ICU nurses facing SV effects is limited, particularly due to the lack of systematic intervention protocols tailored to the specific work scenarios of ICU staff. This study aims to...
