Correction to: Low Life Course Socioeconomic Status (SES) Is Associated with Negative NEO PI-R Personality Patterns.

After the publication of the original article, the Editor was notified by Duke University that they have determined the authorship to be incomplete. Consequently, Dr Edward Suarez has been added as a co-author to represent his contribution to the conception and design of the work and acquisition of the data.

Relationship Between Optimism and Outcomes in Patients With Chronic Angina Pectoris.

Greater optimism regarding recovery from chronic illness is associated with improved quality of life and clinical outcomes. We performed a post-hoc analysis on the association between optimism and outcomes in Ranolazine in Patients with Incomplete Revascularization after Percutaneous Coronary Intervention (RIVER-PCI), a randomized trial in patients with chronic angina pectoris who had incomplete revascularization following percutaneous coronary intervention. At baseline, patients answered how much they agreed with the phrase, "I am optimistic about my future and returning to a normal lifestyle.

The Effects of Tryptophan Enhancement and Depletion on Plasma Catecholamine Levels in Healthy Individuals.

Objective: Central nervous system (CNS) serotonin (5-HT) exerts both excitatory and inhibitory effects on the sympathetic nervous system (SNS) in animals. In this study, we examine the effects of tryptophan enhancement and depletion on plasma catecholamine levels in humans.

Methods: The total sample consisted of 164 healthy men and women who were tested for 2 days.

Computing a Synthetic Chronic Psychosocial Stress Measurement in Multiple Datasets and its Application in the Replication of G × E Interactions of the EBF1 Gene.

Chronic psychosocial stress adversely affects health and is associated with the development of disease [Williams, 2008]. Systematic epidemiological and genetic studies are needed to uncover genetic variants that interact with stress to modify metabolic responses across the life cycle that are the proximal contributors to the development of cardiovascular disease and precipitation of acute clinical events. Among the central challenges in the field are to perform and replicate gene-by-environment (G × E) studies.
