Randomized Controlled Trial Comparative Study
A randomized trial of an N-methyl-D-aspartate antagonist in treatment-resistant major depression.
Existing therapies for major depression have a lag of onset of action of several weeks, resulting in considerable morbidity. Exploring pharmacological strategies that have rapid onset of antidepressant effects within a few days and that are sustained would have an enormous impact on patient care. Converging lines of evidence suggest the role of the glutamatergic system in the pathophysiology and treatment of mood disorders. ⋯ Robust and rapid antidepressant effects resulted from a single intravenous dose of an N-methyl-D-aspartate antagonist; onset occurred within 2 hours postinfusion and continued to remain significant for 1 week.

Depression is associated with clinical events and premature mortality among patients with established coronary artery disease (CAD). Typically, however, studies in this area focus only on baseline symptom severity and lack any data concerning symptom duration or symptom history. ⋯ Among women with suspected myocardial ischemia, a combination of depressive symptom severity and treatment history was a strong predictor of an elevated CAD risk profile and increased risk of cardiac events compared with those without depression or with only 1 of the 2 measured depression markers. These findings reinforce the importance of assessing mental health factors in women at elevated CAD risk. Focusing only on baseline depression symptom severity may provide an incomplete picture of CAD risk.

Randomized Controlled Trial Comparative Study
Prevention of eating disorders in at-risk college-age women.
Eating disorders, an important health problem among college-age women, may be preventable, given that modifiable risk factors for eating disorders have been identified and interventions have been evaluated to reduce these risk factors. ⋯ Among college-age women with high weight and shape concerns, an 8-week, Internet-based cognitive-behavioral intervention can significantly reduce weight and shape concerns for up to 2 years and decrease risk for the onset of EDs, at least in some high-risk groups. To our knowledge, this is the first study to show that EDs can be prevented in high-risk groups.

The Food and Drug Administration has issued a boxed warning concerning increased suicidal ideation and behavior associated with antidepressant drug treatment in children and adolescents. It is unknown whether antidepressant agents increase the risk of suicide death in children or adults. ⋯ In these high-risk patients, antidepressant drug treatment does not seem to be related to suicide attempts and death in adults but might be related in children and adolescents. These findings support careful clinical monitoring during antidepressant drug treatment of severely depressed young people.
