Randomized Controlled Trial
Laser acupuncture for depression: a randomised double blind controlled trial using low intensity laser intervention.
Trials of acupuncture for the treatment of depression have produced mixed results. We examined the effectiveness of laser acupuncture compared with placebo acupuncture for the treatment of major depression. ⋯ Laser acupuncture showed a clinically and statistically significant benefit with reducing symptoms of depression on objective measures.

Alcohol use disorders (AUD) and cannabis use disorders (CUD) are common in the United States (US), and are associated with major depressive disorder (MDD). Co-occurring alcohol and cannabis use/use disorders (AUD+CUD), though understudied, have been found to be associated with greater adverse outcomes than alcohol or cannabis use/use disorders alone. There is a paucity of research on the co-occurring relationships of the two disorders with depression. ⋯ Positive associations between AUD, CUD and MDD were observed bidirectionally. Findings have implications for preventive and treatment programs and initiatives.

Several polymorphic variants within the catechol-O-methyltransferase (COMT) gene locus have been associated with a number of diverse psychiatric phenotypes including affective disorders. COMT enzyme participates in metabolic pathways involving brain catecholamines, as well as steroid hormones such as estrogens. Given the suggested mood enhancing role of estrogens and the higher prevalence of depression in women, we set out to investigate the potential impact of functional COMT genetic variants on depression and anxiety symptoms in a homogeneous female community sample. ⋯ Our results provide promising evidence that MB-COMT specific genetic variation may represent an as yet unrecognized genetic factor that influences predisposition to depression amongst females.

Randomized Controlled Trial
Internet-based behavioral activation and acceptance-based treatment for depression: a randomized controlled trial.
Internet-based cognitive behavior therapy for depression has been tested in several trials but there are no internet studies on behavioral activation (BA), and no studies on BA over the internet including components of acceptance and commitment therapy (ACT). The aim of this study was to develop and test the effects of internet-delivered BA combined with ACT against a waiting list control condition as a first test of the effects of treatment. ⋯ We conclude that there is initial evidence that BA with components of ACT can be effective in reducing symptoms of depression.

Multicenter Study
Melancholic features and hostility are associated with suicidality risk in Asian patients with major depressive disorder.
Suicide rates are higher in East-Asians than other populations, and especially high in Koreans. However, little is known about suicidality risk and melancholic features in Asian patients with major depressive disorder (MDD). ⋯ Suicidality risk is associated with both melancholic features and hostility and it shows cross-ethnic differences in Asian MDD patients, independent of depression severity.
