The INTEGRATE study aimed to provide information on the use, effectiveness, and safety of esketamine nasal spray (ESK-NS) for the treatment of treatment-resistant depression (TRD) in real-world practice in Spain. This was an observational, cross-sectional, retrospective study conducted in adults aged 18-74 years who met the criteria for TRD. The weekly impact of ESK-NS on depressive symptoms...
Emerging viral pathogens, newly reported or rapidly evolving viruses, are a significant public health concern worldwide. Beyond their characteristic clinical presentations, emerging viruses, such as monkeypox virus (MPXV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have been increasingly implicated in the development of various neuropsychiatric complications including...
Ketamine, a dissociative anesthetic with well documented abuse liability, can also provide rapid-onset and persistent antidepressant effects and is currently used for the management of treatment-resistant depression. Although the precise neurobiological mechanisms underlying its antidepressant actions are not fully determined, a critical feature of ketamine's clinical efficacy may be its...
Rapid sequence induction (RSI) is a potentially-life saving intervention in critically ill patients. An important adverse effect of this procedure is post-induction hypotension (PIH), which is associated with worsened patient outcomes. Choice of induction agent can affect incidence of PIH, although the optimal drug has yet to be determined. Ketamine is postulated to reduce PIH incidence in...

Data show that recreational ketamine use appears to be increasing. This study aimed to understand how ketamine fits into broader polysubstance use in individuals with opioid use disorder (OUD). Survey data were collected from a sample of treatment-seeking individuals with OUD in March 2022. Of 301 respondents, 28.6% reported lifetime ketamine use. Ketamine use was more frequently reported among...
Ketamine, a dissociative anesthetic, has gained widespread use in various medical contexts, including anesthesia, pain management, and treatment-resistant depression. Despite its therapeutic potential, concerns regarding its safety profile have prompted ongoing research and regulatory guidance. This comprehensive literature review explores the current safety considerations of ketamine,...
Paradoxical vocal cord motion (PVCM) is a primarily neuropsychiatric condition that causes inappropriate adduction of the vocal cords during respiration. This condition is commonly misdiagnosed and treated as refractory asthma or upper airway obstruction requiring intensive care unit-level of care. Recent expert opinion suggests that ketamine administration may promote PVCM symptom resolution;...
To compare the effects of two different protocols, ketamine with dexmedetomidine (ketamine-dexmedetomidine [KD]) and ketamine with propofol (ketamine-propofol [KP]), on intubation time, selected cardiopulmonary parameters, and anaesthesia maintenance during canine orchiectomy in a clinical setting. Randomized clinical trial. Twenty-six healthy dogs were undergoing orchiectomy. Dogs were...
Depression is a severe and recurrent neuropsychiatric disease with high prevalence, disability, and mortality, which imposes a heavy burden on national public health and the economy. Traditional antidepressants demonstrate delayed effects, low cure rates, and inadequate therapeutic effectiveness for managing treatment-resistant depression. Numerous studies have proved that esketamine, a...
Posttraumatic stress disorder (PTSD)/blast traumatic brain injury (bTBI) in a Special Operations Forces (SOF) cohort has been shown to be successfully treated using a cervical sympathetic blockade (CSB)/ketamine infusion (KI) combination, termed the SOF method. In a prior case report, the patient was followed for 1 year. This report followed the same patient for a total of 720 days and found...
Nebulized ketamine, an innovative route of drug delivery, has gained interest for its potential effectiveness in challenging clinical scenarios. The objective of this systematic review is to provide insights into the safety and effectiveness of nebulized ketamine in pain management. A systematic search was performed on online databases including WOS, Cochrane, Scopus, and PubMed, using a...
Ketamine is currently gaining attention as a rapid-acting antidepressant for treatment-resistant depression (TRD). However, many patients fail to respond, and limited data exist on predictors of non-response. This study aims to characterize the sociodemographic and clinical features associated with non-response to ketamine among TRD patients. This is a post-hoc analysis of a naturalistic...
Chronic postsurgical pain (CPSP) is a debilitating condition that affects up to 50% of patients after procedures like inguinal herniorrhaphy, significantly impairing quality of life. This case report describes a 63-year-old male who experienced refractory CPSP for 5 years following inguinal hernia repair. The patient reported persistent pain despite multiple pharmacological treatments,...
Mitochondrial dysfunction and oxidative stress may contribute to schizophrenia. Negative symptoms and cognitive dysfunction in individuals with schizophrenia are resistant to anti-psychotic medications, but physical exercise is an effective treatment. Exercise’s beneficial effects involve releasing irisin from skeletal muscle by activating mitochondrial peroxisome proliferator-activated...
Esketamine has shown promise in mitigating tissue damage caused by ischemia- reperfusion injury, making it a potential therapeutic candidate for acute lung injury (ALI) induced by limb ischemia-reperfusion (LIR-ALI). This study sought to explore the role and mechanism of esketamine in the LIR-ALI rat model. The effects of esketamine on the LIR-ALI rats model were evaluated through...
Major depressive disorder (MDD) is a debilitating mental health condition characterized by significant morbidity and mortality. The emergence of ketamine infusion therapy has provided a promising, rapidly acting treatment option. We aimed to assess the effectiveness of ketamine infusion therapy as an adjunct treatment in patients with depression and to study the patient's profile undergoing...
Introduction: Treatment-resistant depression (TRD) affects over 30 % of patients with depression and is associated with high morbidity and mortality. Intravenous (IV) ketamine has shown rapid and robust antidepressant effects for TRD. However, limited data exist on long-term maintenance and patient experiences, especially in North America. This study aims to explore the lived experiences of...
Professional practice guidelines for the use of ketamine in psychiatric practice have been developed by the Royal Australian and New Zealand College of Psychiatrists to provide guidance on the use of ketamine in clinical practice in Australia and Aotearoa New Zealand, based on scientific evidence and supplemented by expert clinical consensus. Articles and information were sourced from existing...
