( JAMA Network Open . 2025;8(2):e2459331. doi: 10.1001/jamanetworkopen.2024.59331) Postpartum depression (PPD) is a widespread condition affecting about 17.7% of new mothers globally, with an even higher incidence of 21.4% reported in China. Cesarean birth (CB) appears to increase the risk of developing PPD compared to vaginal births. Given the growing recognition of esketamine, a derivative of...
Perioperative (es)ketamine significantly reduces POD risk but not POND. Subgroup analyses reveal esketamine excels in delirium prevention, while racemic ketamine shows better cognitive protection.
Ketamine was shown to promote synaptogenesis, which is thought to account for its antidepressant effects through the restoration of lost synaptic connections observed in depression. PET imaging using 11C-UCB-J, a radiotracer targeting the synaptic vesicle protein 2 A (SV2A), was investigated as a translational method to monitor ketamine-induced changes in synaptic density in the corticosterone...
Treatment-resistant depression (TRD) is associated with worse clinical outcomes and longer course of illness. However, TRD is more difficult to model in animal phenotypes, suggesting that other experimental and translational models must be considered to properly address and research novel therapeutics. Reelin, an endogenous glycoprotein downregulated in depression, has shown rapid...

Chronic pain is highly prevalent among Veterans and contributes to poor surgical recovery. This pilot quality improvement project evaluated a structured postoperative ketamine infusion program at a Veterans Affairs medical center. Veterans with chronic pain undergoing complex surgery received low-dose ketamine infusions (0.2 mg/kg/hr) for 24-72 hours postoperatively. The Quality of Recovery-15...
Alcohol use disorder (AUD) represents a significant medical challenge, with available therapeutic approaches having limited efficacy. Emerging data suggest that psychedelic compounds could represent an alternative treatment for AUD. Among this class of molecules, ketamine, a dissociative psychedelic, shows promising properties. It reduces alcohol drinking in rodents and in humans it is used to...
Objective: To investigate the clinical application effect of ciprofol combined with low-dose esketamine in painless gastrointestinal endoscopy. Methods: A retrospective analysis was conducted on the clinical data of 160 patients who underwent painless gastrointestinal endoscopy at the Digestive Endoscopy Center of Chengdu Integrated Traditional Chinese and Western Medicine Hospital from June...
This study evaluated intramuscular (IM) ketamine's efficacy and safety for rapid suicidal ideation reduction, addressing the critical need for fast-acting interventions in resource-limited settings where intravenous (IV) options are impractical. We conducted a pre-post-interventional study of IM ketamine (0.5 mg/kg) over one year after approval of the institutional ethics committee. Adult...
Current evidence suggests that ketamine/esketamine may be effective in alleviating POF, particularly in major abdominal surgeries. These findings should be interpreted cautiously due to the heterogeneity in study designs, variations in fatigue assessment tools and time, and the limited sample sizes of the included studies. Future high-quality RCTs are needed to confirm these observations and...
Ketamine exhibits superior efficacy compared to conventional antidepressants, yet its clinical application remains limited by dose-dependent side effects. Ascorbic acid (AA) augments ketamine's antidepressant-like effects, suggesting that AA co-administration with subtherapeutic ketamine doses may achieve optimal efficacy while improving safety. Since AA itself lacks independently clinical...
