DSM׳s replacement of 'mixed episodes' with 'mixed features' has ironically created a specifier, which potentially lacks specificity because it overlooks two key symptoms: psychomotor agitation and distractibility. Therefore, the present study examined the presence of psychomotor agitation and distractibility across the mood disorder spectrum. ⋯ The present findings suggest that distractibility and psychomotor agitation may represent the core of mixed states, as they are more common in patients with mixed depression and bipolar spectrum disorder than patients diagnosed with unipolar depression and bipolar I disorder. Future research and clinical implications are discussed.

Effect of music therapy during vaginal delivery on postpartum pain relief and mental health.
Childbirth is an important experience in a woman's life, and unfavorable birth experiences have been shown to negatively impact postpartum maternal health. Aim of this study was to evaluate the effects of music therapy on postpartum pain, anxiety level, satisfaction and early pospartum depression rate. ⋯ Using music therapy during labor decreased postpartum anxiety and pain, increased the satisfaction with childbirth and reduced early postpartum depression rate. Music therapy can be clinically recommended as an alternative, safe, easy and enjoyable nonpharmacological method for postpartum well-being.

Recent research has seen low-dose ketamine emerge as a novel, rapid-acting antidepressant. Ketamine, an N-methy-d-aspartate (NMDA) receptor antagonist, leads to effects on the glutamatergic system and abnormalities in this neurotransmittor system are present in depression. This article aims to (1) review the clinical literature on low-dose ketamine as a rapid-acting antidepressant in affective disorders, (2) provide a critical overview of the limitations of ketamine and research attempts to overcome these (3) discuss the proposed mechanisms of action of ketamine and (4) point towards future research directions. ⋯ Current and future research studies are using ketamine as a promising tool to evaluate the glutamatergic neurotransmittor system to learn more about the pathophysiology of depression and develop more specific rapid-acting antidepressant treatments.

Prior to recent FDA approval of lurasidone for treatment of bipolar depression there were only two approved treatments for this condition (quetiapine and olanzapine-fluoxetine combination), and these were as likely to provide therapeutic benefit as adverse effects. We assessed the efficacy, safety, and tolerability of lurasidone for major depressive episodes associated with bipolar I disorder, using number needed to treat (NNT, for benefits), number needed to harm (NNH, for harms), and likelihood of being helped or harmed (LHH, ratio of NNH to NNT, for trade-offs between benefits vs. harms). ⋯ NNT, NNH, and LHH help quantify relative benefits (efficacy) and harms (side effects), thus placing lurasidone findings in research studies into clinical perspective. Lurasidone, compared to other treatments approved for bipolar depression, yielded comparable benefits (all had single-digit NNT vs. placebo for response or remission), and less risk of harm (double-digit or greater NNHs with lurasidone compared to single-digit NNHs for sedation with quetiapine and for ≥7% weight gain with olanzapine-fluoxetine combination), and thus a substantially more favorable LHH (> or >1) with lurasidone monotherapy and adjunctive therapy, compared to quetiapine and olanzapine-fluoxetine combination (LHH

Depression and anxiety have been associated with a range of symptoms that often overlap. Depression, Anxiety and Stress Scale-21 (DASS-21) is a single instrument to assess symptoms of depression, anxiety and stress. This study aimed to adapt and validate the DASS-21 for use in the Brazilian Portuguese language. ⋯ The findings support the validity of the Brazilian Portuguese version of the DASS-21 and add to the evidence of the DASS-21 quality and ability to assess emotional states separately, eliminating the use of different instruments to assess these states.
