Chronic stress is a risk factor for depression and may contribute to treatment resistance. This historical cohort study examined the association between baseline perceived stress, measured with the Perceived Stress Scale (PSS), and response to (es) ketamine in treatment-resistant depression (TRD). Adult TRD patients who received intravenous racemic ketamine or intranasal esketamine were...
Approximately 30 % of patients with treatment-resistant depression (TRD) respond to ketamine; however, no replicable predictors of response have been reported. The imbalance between excitatory and inhibitory neurotransmissions may be implicated in the mechanism of action of ketamine. This study aimed to evaluate whether the ratio of glutamate and glutamine (Glx) to GABA levels at baseline in...
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...
Holistic management of persons living with Major Depressive Disorder (MDD) and Bipolar Disorder (BD) invites the need for evaluation of positive mental health (PMH; pleasure attainment and meaning-in-life), alongside conventional measures of psychopathology. The aforementioned dimensions of PMH involve aspects of mindfulness and grit. Herein, we evaluate these aspects using ecological momentary...
Accumulating evidence suggests that psilocybin can produce rapid and sustained clinical benefits when administered in conjunction with psychological support. Though non-pharmacological procedures are considered integral, the field lacks therapeutic guidelines and little is known about current practices. This systematic review sought to provide a comprehensive and cross-diagnostic synthesis of...
Despite recent clinical and research interest, medical use of psychedelics has not been legalised in most jurisdictions. The Australian Therapeutic Goods Administration rescheduled methylenedioxymethamphetamine (MDMA) in July 2023 to permit authorised prescribing of MDMA for Post-traumatic Stress Disorder (PTSD) outside of the clinical trial setting. This manuscript describes the development of...
Depression and PTSD are prevalent psychiatric conditions that often co-occur and significantly impact quality of life. Ketamine has emerged as a promising rapid-acting treatment for both conditions, while traditional treatments like psychotherapy typically require weeks to show effects. This study investigated whether combining ketamine with psychotherapy produces greater symptom improvement...
Menopause, a crucial transitioning stage for women, can significantly impact mood and wellbeing. We aimed to systematically examine the effectiveness of Mindfulness-based interventions (MBIs) on health outcomes, including menopausal symptoms, quality of life (QOL), sleep quality, anxiety, depressive symptoms, stress, mindfulness levels, and female sexual function index. Eight databases were...
Intranasal (IN) esketamine was approved as a therapy for treatment-resistant depression in March 2019. There continues to be interest in the field to better understand factors associated with response to treatment. The aim of the current study is to assess the association between BMI and response to esketamine. A retrospective analysis was conducted on all patients treated with intranasal...
Ketamine and electroconvulsive therapy (ECT) are among the recommended treatments for treatment resistant depression (TRD). However, there is a subset of patients who do not respond to either treatment, making it insufficient to address their condition. To determine the efficacy of concurrent therapy with ECT and intravenous racemic ketamine in TRD. This retrospective study included a total of...
The endogenous opioid system is thought to play a role in the placebo antidepressant response. A recent trial comparing the rapid antidepressant effects of ketamine versus placebo in surgical patients, some of whom were on chronic opioid therapy, revealed a substantial placebo effect. This finding provided an opportunity to test the hypothesis that opioid agonist exposure interacts with placebo...
While growing evidence suggests that psychedelic-assisted therapy may have antidepressant effects in certain populations, little is known about the effects of psychedelic use on depressive symptoms in non-clinical, naturalistic settings. This observational cohort study included a large sample of US residents (18-50 years old) and longitudinally evaluated the relationships between naturalistic...
Electroconvulsive therapy (ECT) and intravenous (IV) ketamine are treatments used for severe depression and/or treatment-resistant depression (TRD). ECT is considered one of the most effective treatments for severe depression, although there is debate within the field regarding the effectiveness between ECT and IV ketamine in comparable TRD patient groups. This retrospective chart review of...
Mindfulness-based therapies (MBT) are proposed as a "third wave" of cognitive-behavioral therapy (CBT). This network meta-analysis investigated this hypothesis by comparing the effectiveness of MBT and CBT for treating depression, measured by the Beck Depression Inventory-II (BDI-II). An indirect comparison was made. Relevant databases were searched for studies comparing either CBT or MBT with...
Mindfulness-based cognitive therapy (MBCT) has emerged as a promising intervention for generalized anxiety disorder (GAD). This study evaluated MBCT's effectiveness for GAD and examined whether childhood maltreatment moderates its impact. Individuals with GAD were randomized to receive one of two 8-week interventions, either MBCT in-person or psychoeducation on-line (n = 27 per group). At...
Dissociative symptoms are commonly observed in a substantial minority of patients with Post-Traumatic Stress Disorder (PTSD) and during the first administration of esketamine for the treatment of Treatment-Resistant Depression (TRD). We examine differences in the number and pattern of dissociative symptoms (depersonalization, derealization, dissociative amnesia, identity fragmentation) reported...
According to recent research, esketamine may reduce the incidence of postpartum depression (PPD) risk following cesarean delivery. To further assess this potential benefit, a meta-analysis was conducted. Embase, Web of Science, the Cochrane Library, and PubMed were searched from inception through March 2025. Meta-analysis was performed using random-effects models to calculate risk ratios (RRs)...
One-third of Veterans with major depressive disorder suffer from treatment-resistant depression (TRD). This is the first study to evaluate the long-term outcomes of psilocybin in Veterans with severe TRD. This paper presents 12-month results from an open-label pilot study assessing the effects of 25 mg psilocybin in Veterans with severe TRD, defined as a major depressive episode failing to...
Esketamine is increasingly used to induce general anesthesia in pediatric populations. However, its neurological effects on healthy individuals-especially during early developmental stages-remain a topic of ongoing debate. In particular, concerns persist regarding its impact on the developing brain at extreme ages. Furthermore, the molecular mechanisms underlying these effects have not yet been...
Interventions to cope with emotional states (depression, stress, and anxiety) and strengthen attachment are important. This research aims to determine the effect of the Mindfulness-Based Childbirth and Parenting Program (MBCP) on pregnant women's prenatal attachment and their levels of depression, stress, and anxiety. This randomized controlled trial included 36 participants who were randomly...
Ketamine's use in treating bipolar depression must account for risks, such as switching to manic episodes or worsening symptoms. This study examines ketamine's impact on depressive symptoms, focusing on 'inner tension,' 'sleep reduction,' and 'suicidal ideation' over four weeks in treatment-resistant bipolar disorder (TR-BD) patients. Fifty-nine patients with TR-BD were treated consecutively...
Depression is a common and serious psychiatric disorder with significant impacts on individuals. Modified electroconvulsive therapy (MECT) is an established treatment for severe and treatment-resistant depression, but its cognitive side effects, particularly memory impairments, limit its use. Esketamine (ESK), an FDA-approved antidepressant, has shown neuroprotective effects. However, its role...
To determine whether there is disproportionate reporting of hepatobiliary disorders in the United States (US) FDA Adverse Event Reporting System (FAERS) for individuals prescribed ketamine or esketamine. We identified Medical Dictionary for Regulatory Activities (MedDRA) terms in the FAERS related to hepatobiliary disorders. Formulations of ketamine and esketamine were evaluated for the...
Subanesthetic doses of (R,S)-ketamine (ketamine) have demonstrated rapid and robust antidepressant effects in individuals with depression. However, individual variability in response to ketamine exists, and current biomarkers of ketamine treatment response are not entirely understood. Preclinical evidence suggests a link between hypothalamic-pituitary-adrenal (HPA) axis activation, a...
Ketamine's potential for treating depression has drawn increased clinical interest in recent years. However, despite growing therapeutic use, recreational use among individuals with depression remain underexplored. We analyzed data from the 2015-2022 National Survey on Drug Use and Health focusing on adults in the US. Trends in past-year ketamine use, overall and by depression status, were...
