A randomized placebo-controlled trial tested whether a fixed low dose of oral esketamine (30 mg three times daily) could reduce depression severity in patients with treatment-resistant depression. Over six weeks, the drug showed no benefit compared to placebo on the Hamilton Depression Rating Scale. Dizziness and sleep hallucinations were more common with esketamine. In an open-label extension phase where doses were individually titrated up to 3.0 mg/kg twice weekly, depressive symptoms decreased substantially. The findings suggest that fixed low-dose oral esketamine is ineffective, but individually adjusted higher doses may hold promise for treatment-resistant depression.

About half of people with treatment-resistant depression do not respond to (es)ketamine, despite its known efficacy. This systematic review of 44 studies examined whether demographic or clinical traits predict who will respond or remit after (es)ketamine treatment. Overall, most demographic and clinical variables showed no consistent predictive value. Preliminary evidence linked better response to anhedonia, sleep disturbances, childhood physical abuse, obesity, openness, better episodic memory and visual learning, poorer neurocognitive performance, slower processing speed, and lower attention, while melancholic depression, benzodiazepine use, and metabolic syndrome were linked to worse response. These associations need replication, but suggest (es)ketamine may benefit patients with characteristics often considered hard to treat.

Mindfulness-based cognitive therapy (MBCT) added to treatment as usual reduced depressive symptoms and overall functional impairment more than treatment as usual alone in patients with persistent or recurrent major depressive disorder, with medium and small effect sizes respectively. The therapy worked better for those who started with higher levels of rumination and perseverative thinking and lower levels of self-compassion; these traits moderated the treatment's effects. No mediators of MBCT's effects were identified, as the therapy did not change the assessed potential mediators by mid-treatment. Allocating MBCT based on patients' rumination and self-compassion levels could make symptom reduction more efficient.

Oral esketamine, taken twice weekly for six weeks at doses from 0.5 to 3 mg/kg, reduced depressive symptom severity in adults with severe treatment-resistant depression who had not benefited from an average of 8.1 prior antidepressant trials and, in 63% of cases, electroconvulsive therapy. Hamilton Depression Rating Scale scores dropped from 21.2 to 15.8. Nearly half of participants achieved a clinically meaningful improvement, 26.8% responded, and 15.6% remitted. Side effects were common but well tolerated, with a 7.6% dropout rate and no significant urinary or cognitive adverse effects. Treatment continued beyond six weeks in 45.9% of participants to maintain gains.

Elevated stress, anxiety, and depression are common among Indonesian undergraduates, but access to mental healthcare is difficult and costly, and many avoid professional help. This randomized controlled trial tests whether a 14-day online mindfulness intervention reduces stress, anxiety, depressive symptoms, and repetitive negative thinking (RNT) compared to psychoeducation and waitlist controls. The study also examines whether changes in RNT explain mindfulness's effects on these outcomes. Measures are taken at baseline, post-intervention, and at a 3-month follow-up. The trial aims to provide evidence that a brief, accessible online mindfulness program could be a low-threshold strategy for improving mental health in Indonesia.
