Ketamine is used frequently as an adjunct for general anaesthesia, exerting analgesic and opioid-sparing properties at lower doses and psychotomimetic effects at higher doses. All dose ranges may have effects on the incidence of postoperative delirium, but clinical trials have been equivocal. We hypothesised that intra-operative low-dose ketamine is associated with a lower risk of postoperative...
Psychedelic-assisted therapies and ketamine are two modalities gaining attention in psychiatry for treating conditions such as depression, PTSD, and substance use disorders. However, perceptions of these treatments vary globally. This study explores the familiarity, attitudes, and perceptions of Jordanian physicians and medical students toward psychedelic substances, addressing a gap in Middle...

This study compared the effects of ketamine and dexmedetomidine (Dex) on inflammation and pain in liver resection surgery. Forty-five American Society of Anesthesiologists class III patients aged 18 to 65 scheduled for liver resection surgery were randomized into 3 equal groups. The ketamine group received an intravenous ketamine bolus (0.5 mg/kg) during anesthesia induction and continuous...
Imbalances in redox and neuroinflammation are believed to play a role in the complex causes of schizophrenia, a widespread mental disorder characterized by abnormal behaviour. In this regard, we investigated the effects of geraniol, a natural compound with various medicinal uses, on ketamine-induced schizophrenia-like behaviour, oxidative stress and neuroinflammation in mice. We conducted three...
Psychedelic compounds such as ketamine and MDMA have shown therapeutic promise for mood and trauma-related disorders, yet their molecular mechanisms remain unclear. This study applied a Brain-Epigenome-Wide Association Study (BEWAS) to assess DNA methylation changes in brain-enriched genes following treatment. Pre- and post-treatment blood (ketamine, N = 20) and saliva (MDMA, N = 16) samples...
Ketamine-assisted therapy (KAT) is a novel modality that shows promise as a treatment for depression. The current study sought to add to the scarce research in the area and inform future applications of KAT for patients with treatment-resistant depression. The study used in-depth qualitative interviews (N = 12) to explore participants' perceptions of KAT, including working with therapists, the...
Treatment-resistant depression (TRD) remains a significant clinical challenge, often accompanied by polypharmacy and comorbid anxiety or trauma-related disorders. This report describes a 37-year-old male with longstanding major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and social anxiety disorder who demonstrated limited response to traditional pharmacologic strategies,...
The novel antidepressant ketamine has been shown to achieve what most classic antidepressants, such as Selective Serotonin Reuptake Inhibitors, have not been able to. A rapid onset of symptomatic improvement across multiple domains; mood, anhedonia, and suicidal ideation. The exact neuropsychopharmacological mechanisms of this unique phenomenon are still unknown, although many theories are...
Schizophrenia is a highly disabling psychopathology that is a significant burden on public health systems and is characterized by both positive and negative symptoms. One of these negative symptoms is social isolation, which responds poorly to available treatments. Ketamine (KET) has been shown to enhance social behavior in various preclinical models, accompanied by neurobiological changes. In...
Ketamine is a rapid-acting antidepressant with sexually dimorphic effects. Female animals exhibit a higher sensitivity to its antidepressant properties, which has been associated with their ovarian hormone levels. One factor contributing to this sex difference is the faster rate of ketamine metabolism observed in females, potentially regulated by estrogen receptor alpha (ERα) through modulation...
