Although esketamine shows efficacy for treatment-resistant depression, its potential effectiveness in cancer-related depression (CRD) has not been well-established. We therefore evaluated the real-world effectiveness and safety of esketamine in CRD using a target trial emulation framework based on anonymized electronic health records from the TriNetX network. Adults aged 18-74 years with CRD...

Major depressive disorder (MDD) is a leading cause of disability worldwide, and currently available antidepressants remain limited by delayed onset of action, incomplete response, and adverse effects. Ketamine is a rapid-acting antidepressant, whereas xanomeline, an M1/M4 muscarinic receptor agonist, may represent a mechanistically distinct non-monoaminergic strategy. However, the molecular...

Background: Depression, anxiety,, and PTSD are leading global causes of disability. Standard interventions utilize slow mechanisms of action, high attrition, and significant accessibility barriers. While intravenous (IV) and intranasal ketamine are rapid-acting alternatives, high cost and intensive logistical requirements limit adoption. Sublingual (SL) at-home ketamine addresses some gaps but...

Slow-wave activity (SWA), a key indicator of sleep homeostasis, is often diminished in individuals with treatment-resistant depression (TRD). Ketamine, a rapid-acting antidepressant, increases SWA during the first period of non-rapid eye movement (NREM1) sleep. However, research into how ketamine affects sleep and its connection to treatment outcomes in TRD has been limited by small sample...

Borderline personality disorder (BPD) often occurs alongside treatment-resistant depression (TRD), but the impact of BPD on real-world outcomes with intranasal esketamine is unclear. Consecutive TRD outpatients initiating intranasal esketamine treatment at four Italian centres between 1 September 2024 and 30 September 2025 were enrolled in the study (n = 90): 45 with comorbid BPD and 45 without...

Background: Depression is a multifactorial disorder involving neurotransmitter dysregulation, HPA axis hyperactivity, neuroinflammation, and impaired neuroplasticity. While combination psychotherapy and pharmacotherapy remains first-line, ~30% of patients develop TRD. In the last few years ketamine has emerged as a rapid-acting therapeutic option for treatment-resistant cases. Aim: To review...

Pancreaticoduodenectomy (PD) can lead to major trauma in terms of patients' mental health, including severe postoperative depression. This study aimed to investigate the effects of supplementing patient-controlled analgesia with low-dose esketamine on postoperative depression among patients undergoing PD. Eighty patients who were scheduled for PD were randomly assigned to either the control or...

For many patients with major depressive disorder, reaching remission — not just partial response — can significantly alter the course of illness, lowering the risk of relapse and improving day‐to‐day functioning. Yet that goal remains elusive for those with treatment‐resistant depression (TRD), where repeated medication failures, comorbid conditions, and lingering symptoms complicate care. Data...

Background: Treatment-resistant depression (TRD) poses a major clinical challenge, particularly when accompanied by suicidal behavior. Intranasal esketamine has demonstrated rapid antidepressant effects in TRD, but real-world comparative evidence remains limited. Methods: We conducted a six-month naturalistic prospective cohort study in two Spanish mental health centers, including 62 TRD...
