Randomized Controlled Trial Multicenter Study Clinical Trial
Effects of treating depression and low perceived social support on clinical events after myocardial infarction: the Enhancing Recovery in Coronary Heart Disease Patients (ENRICHD) Randomized Trial.
Depression and low perceived social support (LPSS) after myocardial infarction (MI) are associated with higher morbidity and mortality, but little is known about whether this excess risk can be reduced through treatment. ⋯ The intervention did not increase event-free survival. The intervention improved depression and social isolation, although the relative improvement in the psychosocial intervention group compared with the usual care group was less than expected due to substantial improvement in usual care patients.

Regional brain metabolic correlates of alpha-methylparatyrosine-induced depressive symptoms: implications for the neural circuitry of depression.
We previously used positron emission tomography (PET) measurement of brain metabolism with 18fluorodeoxyglucose to show that patients receiving selective serotonin reuptake inhibitors (SSRIs) who have a tryptophan depletion-induced return of depressive symptoms have an acute decrease in metabolism in orbitofrontal cortex, dorsolateral prefrontal cortex, and thalamus. Many patients with depression in remission while taking norepinephrine reuptake inhibitors (NRIs) (but not SSRIs) experience a return of depressive symptoms with depletion of norepinephrine and dopamine using alpha-methylparatyrosine (AMPT). ⋯ Different neurochemical systems that mediate depression may have effects on a common brain circuitry. Baseline metabolism in successfully treated depressed patients may predict vulnerability to future episodes of depression.

Group interpersonal psychotherapy for depression in rural Uganda: a randomized controlled trial.
Despite the importance of mental illness in Africa, few controlled intervention trials related to this problem have been published. ⋯ Group interpersonal psychotherapy was highly efficacious in reducing depression and dysfunction. A clinical trial proved feasible in the local setting. Both findings should encourage similar trials in similar settings in Africa and beyond.

Aspirin and ticlopidine for prevention of recurrent stroke in black patients: a randomized trial.
Blacks are disproportionately affected by stroke, and they are about 2 times more likely than most other individuals in the United States to die of or experience stroke. ⋯ During a 2-year follow-up, we found no statistically significant difference between ticlopidine and aspirin in the prevention of recurrent stroke, myocardial infarction, or vascular death. However, there was a nonsignificant trend for reduction of fatal or nonfatal stroke among those in the aspirin group. Based on these data and the risk of serious adverse events with ticlopidine, we regard aspirin as a better treatment for aspirin-tolerant black patients with noncardioembolic ischemic stroke.

Effects of rofecoxib or naproxen vs placebo on Alzheimer disease progression: a randomized controlled trial.
Laboratory evidence that inflammatory mechanisms contribute to neuronal injury in Alzheimer disease (AD), along with epidemiological evidence, suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) may favorably influence the course of the disease. ⋯ The results of this study indicate that rofecoxib or low-dose naproxen does not slow cognitive decline in patients with mild-to-moderate AD.
