Mindfulness-based stress reduction (MBSR) intervention has been widely used to reduce the burden of symptoms in cancer patients, and its effectiveness has been proven. However, the effectiveness of MBSR on depression, anxiety, fatigue, quality of life (QOL), posttraumatic growth (PTG), fear of cancer recurrence (FCR), pain, and sleep in breast cancer patients has not yet been determined. This...
Increased stress among medical students in military college has been a challenge in the field of education. One approach to addressing stress reduction is mindfulness training. MBSR has been verified to improve the health status of different individuals. The aim of this study was to examine whether MBSR improves the psychological resilience, posttraumatic stress and posttraumatic growth of...
Meditation retreats are structured programs that immerse participants in focused meditation, mindfulness, and self-reflection over extended periods. Unlike conventional vacations, which prioritize relaxation, meditation retreats combine intensive practice with intentional rest, cultivating emotional regulation, mindfulness, and personal growth. These retreats have grown in popularity for their...
In a previously published randomized controlled trial, automated self-association training (ASAT), a novel digital intervention, was found to extend the rapid antidepressant effect of a single infusion of ketamine for at least 30 days. In this secondary analysis, we aimed to understand the potential role of implicit self-esteem in the combined antidepressant effect of ketamine and ASAT...
Prevailing hypotheses on the mechanisms of antidepressant action posit that antidepressants directly counteract deficiencies in major neurotransmitter signaling systems that underlie depression. The rapidly acting antidepressant ketamine has been postulated to correct excess glutamatergic signaling via glutamatergic antagonism leading to the rescue of neuronal structural deficits and reversal...
(R,S)-ketamine (ketamine) has rapid and sustained antidepressant (AD) efficacy at sub-anesthetic doses in depressed patients. A metabolite of ketamine, including (2R,6R)-hydroxynorketamine ((6)-HNKs) has been reported to exert antidepressant actions in rodent model of anxiety/depression. To further understand the specific role of ketamine's metabolism in the AD actions of the drug, we evaluated...
(R,S)-Ketamine (ketamine) is a dissociative anesthetic that also possesses analgesic and antidepressant activity. Undesirable dissociative side effects and misuse potential limit expanded use of ketamine in several mental health disorders despite promising clinical activity and intensifying medical need. (2R,6R)-Hydroxynorketamine (RR-HNK) is a metabolite of ketamine that lacks anesthetic and...

Ketamine is a potent sedative and dissociative anesthetic agent that has been used clinically for over 50 years since it was first developed in the 1960 s as an alternative to phencyclidine (PCP). When compared to PCP, ketamine exhibited a much lower incidence of severe side effects, including hallucinations, leading to its increased popularity in clinical practice. Ketamine was initially used...

Ketamine is a widely used clinical drug that has several functional and clinical applications, including its use as an anaesthetic, analgesic, anti-depressive, anti-suicidal agent, among others. Among its diverse behavioral effects, it influences short-term memory and induces psychedelic effects. At the neural level across different brain areas, it modulates neural firing rates, neural tuning,...
Psychedelics have long been used by individuals seeking peace and a sense of wellness. This article examines widespread adoption of ketamine as a proxy for psychedelics. For ketamine, there is a need to protect vulnerable persons from exploitation that should be balanced against risks of hypermedicalization. This article suggests strategies for striking such a balance, including by carefully...
