Background Paclitaxel (PTX), a broad-spectrum anti-tumor drug, is extensively employed as a first-line chemotherapy for solid tumors, including lung and breast cancers. However, it induces chemotherapy-related pain and anxiety in over 53% of patients. S-ketamine, the S-enantiomer of ketamine, exerts rapid antidepressant effects. In this study, we established a PTX model to examine the effects...
Chronic ketamine exposure results in psychotic and cognitive symptoms that resemble those found in patients with schizophrenia. Emerging evidence suggests that patients with schizophrenia exhibit gut microbiota dysbiosis and decreased levels of short-chain fatty acids (SCFAs) and BDNF, which are related to the severity of psychotic and cognitive symptoms. Dietary inulin can regulate gut...

This study demonstrates the efficacy of single-dose esketamine regimens, administered orally (ED95: 8.2125 mg/kg; 95% CI: 7.4250-8.4597 mg/kg) and intranasally (ED95: 2.1770 mg/kg; 95% CI: 2.0952-2.1958 mg/kg), in mitigating preoperative anxiety within a pediatric population. These findings highlight the safety and efficacy of esketamine for this patient group.
Psychospiritual distress (PSD) causes profound suffering in people with serious illness, yet treatment options are few and evidence of their efficacy is modest. Although high-level evidence is limited, decades of preliminary research suggest that psychedelic-assisted psychotherapy (PAP), including ketamine-assisted psychotherapy (KAP), may alleviate the anxiety, depression, and existential...
Abstract Background: Post-traumatic stress disorder (PTSD) is a common mental health condition affecting approximately 3-6% of the U.S. adult population annually, and is characterized by intrusive symptoms, avoidance, negative cognitive and mood alterations, and hyperarousal following trauma exposure. Ketamine shows promise as a treatment for PTSD in preliminary trials, though real-world...

BACKGROUND: In recent years, evidence has suggested that subanesthetic doses of esketamine may have beneficial effects on perioperative anxiety and depression. Concurrently, various factors contribute to a high incidence of perioperative depression and anxiety in the breast cancer patient population. This study aimed to explore the impact of preoperative induction and intraoperative maintenance...
Background/Objectives: Esketamine-related dissociation is a transient, pharmacologically induced altered state that differs from the trait-like pathological dissociation typically observed in trauma-related conditions. While most studies have quantified these effects using the Clinician-Administered Dissociative States Scale (CADSS), patients' subjective phenomenology and meaning-making remain...
Ketamine, a nonselective NMDA-receptor antagonist, is an emerging therapeutic for treatment-resistant depression and could also be a promising treatment for anxiety and post-traumatic stress disorders. However, preclinical studies in these areas lack methodological standardization, limiting clinical translatability. This review evaluates ketamine's anxiolytic potential in rodents by examining...
The neurotic disorders (e.g., depression, dysthymia, generalized anxiety disorder, panic disorder, agoraphobia, social anxiety, post-traumatic stress disorder, and obsessive-compulsive disorder) are costly and difficult to treat. Diagnosis is based on symptoms not biological causes. Here, we summarize New Zealand-based work developing EEG biomarkers and novel treatments. Working at the...
Introduction: Comorbid conditions such as major depressive disorder, anxiety disorders, and posttraumatic stress disorder are common among Veterans, and the presence of multiple conditions requires innovative treatment approaches. The Newly Institute in Calgary, Alberta, Canada, has introduced a novel intervention combining sublingual ketamine therapy with a medically managed transdiagnostic...
