Depression is associated with poor outcomes in breast cancer patients, with higher prevalence among younger women. Although mindfulness-based interventions (MBIs) have demonstrated therapeutic effects, the mechanisms of intervention effects are poorly understood. We investigated whether rumination, self-kindness, intrusive thoughts about cancer, cancer-related worry, or a sense of meaning and...

With the spread of COVID-19, certain population groups, including pregnant women, were more susceptible than others. This disease can lead to postpartum complications, including mental disorders, in mothers. Few studies have investigated the impact of mindfulness-based interventions on mental health, and the most effective counseling approach to promote mental health has not been identified....

In recent years, Internet Addiction Disorder (IAD) has become a major mental health concern among adolescents, with detrimental effects on social relationships, academic performance, and emotional well-being. The focus of mindfulness-based interventions (MBIs) on improving self-awareness, emotional regulation, and cognitive flexibility has drawn interest in MBIs as possible therapeutic...
Ketamine has been widely used in refractory pain as an opioid adjuvant. Evidence suggests that ketamine can also have an essential role in easing depressive symptoms. Its rapid onset of action makes it a valuable choice in palliative care. We present a case of a 70-year-old man with stage IV renal carcinoma and bone metastasis. The main symptoms included neuropathic pain, depression, and a...

Sub-anesthetic ketamine treatment has been shown to be an effective therapy for treatment-resistant depression and chronic pain. Our group has previously shown that sub-anesthetic ketamine produces acute anti-parkinsonian, and acute anti-dyskinetic effects in preclinical models of Parkinson's disease (PD). Ketamine is a multifunctional drug and exerts effects through blockade of...
Synaptic plasticity occurs via multiple mechanisms to regulate synaptic efficacy. Homeostatic and Hebbian plasticity are two such mechanisms by which neuronal synapses can be altered. Although these two processes are mechanistically distinct, they converge on downstream regulation of AMPA receptor activity to modify glutamatergic neurotransmission. However, much remains to be explored regarding...
The aging process causes anatomical and physiological changes that predispose to the development of late-life depression while reduces the efficacy of classical antidepressants. Novel fast-acting antidepressants such as ketamine might be good candidates to be explored in the context of aging, especially given the lack of previous research on its efficacy for this age period. Thus, the aim of...
Each year, 3-4% of the global population experiences post-traumatic stress disorder (PTSD), a chronic mental disorder with significant social and economic repercussions. Although it has been shown that ketamine can effectively alleviate PTSD symptoms in individuals, the specific mechanism of action underlying its anti-PTSD effects remains unclear. In this study, we investigated how a single,...
Standard antidepressant treatments often take weeks to reach efficacy and are ineffective for many patients. (R,S)-ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has been shown to be a rapid-acting antidepressant and to decrease depressive symptoms within hours of administration. While previous studies have shown the importance of the GluN2B subunit of the NMDA receptor on...
Understanding the precise mechanisms of ketamine is crucial for replicating its rapid antidepressant effects without inducing psychomimetic changes. Here, we explore whether the antidepressant-like effects of ketamine enantiomers are underscored by protection against cytokine-induced reductions in hippocampal neurogenesis and activation of the neurotoxic kynurenine pathway in our...
