Acceptability of escitalopram versus duloxetine in outpatients with depression who did not respond to initial second-generation antidepressants: A randomized, parallel-group, non-inferiority trial.

Backgrounds: Antidepressants are widely used to treat major depressive disorder. First-line treatments with antidepressants are only successful in one-third of patients; however, evidence from randomized controlled trials on second-line treatments is limited. Moreover, recently acceptability is suggested to be a good indicator of overall treatment success.

Prediction and structural equation model of sertraline treatment response in Japanese patients with major depressive disorder.

Objective: The aim of this study was to extract the factors possibly associated with sertraline treatment response and elucidate their interactions and extent of influence.

Methods: Demographic state, stress state, personality, and eight genetic polymorphisms at baseline and clinical symptoms at baseline and 8 weeks were analyzed and examined by logistic regression and a structural equation model in sertraline treatment study of 96 Japanese patients with major depressive disorder.

Results: Non-responders were associated with higher scores of harm avoidance in Temperament and Character Inventory, higher scores (≥24) of 17-item Hamilton Rating Scale for Depression at baseline, recurrence, and 12/12 genotype of the serotonin transporter variable number of tandem repeat polymorphism in intron 2 (5HTTSTin2).

Repetitive transcranial magnetic stimulation induces kf-1 expression in the rat brain.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive approach used for stimulating the brain, and has proven effective in the treatment of depression, however the mechanism of its antidepressant action is unknown. Recently, we have reported the induction of kf-1 in rat frontal cortex and hippocampus after chronic antidepressant treatment and repeated electroconvulsive treatment (ECT). In this study, we demonstrated the induction of kf-1 after rTMS in the rat frontal cortex and hippocampus, but not in hypothalamus.
