Mindfulness-based programmes (MBPs) and practices have demonstrated effects in mental health and well-being, yet questions regarding the target mechanisms that drive change across the population remain unresolved. Five databases were searched for randomised controlled trials that evaluate the indirect effects (IEs) of an MBP or mindfulness practice in relation to mental health and well-being...
Major depressive disorder (MDD) poses a significant global health burden with available treatments limited by inconsistent efficacy and notable side effects. Classic psychedelics, including lysergic acid diethylamide (LSD), have garnered attention for their potential in treating psychiatric disorders. Microdosing, the repeated consumption of sub-hallucinogenic doses of psychedelics, has emerged...
Depression is associated with dysregulated circadian rhythms, but the role of intrinsic clocks in mood-controlling brain regions remains poorly understood. We found increased circadian negative loop and decreased positive clock regulators expression in the medial prefrontal cortex (mPFC) of a mouse model of depression, and a subsequent clock countermodulation by the rapid antidepressant...
Depression is a serious psychiatric disorder with a high incidence of morbidity and mortality and psilocybin with psychotherapy has emerged as a promising potential in the treatment of depressive disorders. A review of psilocybin use in patients with depressive disorders is presented.A search was conducted investigating the use of psilocybin in patients with depressive disorders and treatment...
The development of postpartum depression has been linked to fluctuations in the levels of neurotransmitters in the human body, such as 5-hydroxytryptamine (5-HT), dopamine (DA), noradrenaline (Norepinephrine, NE), and brain derived neurotrophic factor (BDNF). Research has indicated that the antidepressant effect of esketamine are mediated by monoamine transmitters and neurotrophic factors....
Current pharmacological treatments for major depressive disorder (MDD) are often only partially effective, with many patients experiencing no significant benefit, leading to treatment-resistant depression (TRD). Psilocybin, a classical serotonergic psychedelic, has emerged as a notable emerging treatment for such disorders. The aim of this systematic review and meta-analysis is to summarize and...
While nitrous oxide (N2O) has demonstrated antidepressant properties in treatment-resistant major depression (TRD), little is known about neural mechanisms mediating these effects. Employing serial resting-state functional magnetic resonance imaging (rs-fMRI), we compared spatiotemporal effects of inhaled N2O on brain functional connectivity in TRD patients (n=14) and non-depressed healthy...
Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine secreted by the pineal gland during the dark phase of the photoperiod. Its main function is the synchronization of different body rhythms with the dark-light cycle. Research on melatonin has significantly advanced since its discovery and we now know that it has considerable significance in various physiological processes, including...
Introduction: Perinatal depression affects 5-15% of childbearing women. However, literature suggests that Latina women are twice as likely to experience depression during pregnancy. Group telehealth-based interventions are a promising approach to increasing access and reducing barriers to mental health. However, little is known about the experience that Latinas have with navigating this...
Background: Esketamine has received approval as a nasal spray (ESK-NS) for treatment-resistant depression (TRD) and evidence from real-world investigations has confirmed the effectiveness of ESK-NS, albeit with interindividual differences in response. Heart rate variability (HRV), defined as the fluctuation in time interval between consecutive heartbeats, can be used to measure autonomic...
Objective: To evaluate the nursing effect of self-help mindfulness therapy for patients with depression. Methods: 120 cases of depression patients admitted to the Department of Psychosomatic Disorders of our hospital between January 2020 and January 2023 were selected. After being grouped by the random draw method, 60 cases in the observation group adopted self-help mindfulness therapy and 60...

Depression is a global public health challenge that represents the world's largest cause of disability, especially in the context of traditional treatments. One potential solution being explored is psilocybin assisted psychotherapy (PAP) which shows promise for treating depression. A recent study by Rosenblat et al. explores the use of psilocybin in clinical mental care with promising results (1).
Background: The Nightmare Distress Questionnaire (NDQ), known and commonly used for its adequate psychometric properties, is the most widely used instrument for the measurement of nightmare distress. This study aimed to assess the psychometric properties of a newly translated Arabic version of the Nightmare Distress Questionnaire (NDQ-AV). Methods: A total of 546 Lebanese adolescents was...
Ketamine has gained attention for its effective treatment for patients with major depressive disorder (MDD) and suicidal ideation; Despite numerous studies presenting the rapid efficacy, long-term benefit in real-world populations remains poorly characterized. This is a retrospective cohort study using TriNetX US Collaborative Network, a platform aggregating electronic health records (EHRs)...
Objectives: Primary Objective: (1) The objectives of the study are as follows: assessment of the effectiveness of ketamine-based treatment in known patients of various subtypes of depression and (2) assessment of time of onset and duration along with routes of administration and safety of ketamine therapy. Secondary Objective: The objectives of the study are as follows: (1) evaluate changes in...

Breast cancer has become the most common cancer worldwide. Various types of mindfulness-based interventions (e.g., mindfulness-based cognitive therapy, mindfulness-based stress reduction) have been conducted in different delivery methods (including face to face and internet delivered) to help patients with breast cancer mitigate their depression. However, at present, there are no studies that...
There is insufficient evidence to guide dose and frequency optimization with repeated-dose ketamine for depression. This study assessed the value of symptomatic non-improvement after the first few ketamine infusions as a predictor of overall non-response in depression for early decision-making to discontinue treatment. A total of 135 individuals with major depressive disorder or bipolar...
Abstract Effective interventions for neuropsychiatric disorders may work by rebalancing the brain’s functional hierarchical organization. Here we directly investigated the effects of two different serotonergic pharmacological interventions on functional brain hierarchy in major depressive disorder in a two-arm double-blind phase II randomized controlled trial comparing psilocybin therapy (22...
Depression poses a significant global health burden, yet current therapeutic approaches focusing on monoaminergic neurotransmission often fall short of achieving full remission and managing acute episodes effectively. This article explores novel treatment avenues beyond conventional monoaminergic approaches, focusing on emerging strategies targeting glutamatergic modulation,...
