Ethnic minority members may be at risk for state hopelessness following hospitalization for ischemic heart disease.

OBJECTIVE: To examine differences in state and trait hopelessness between ethnic minority and White patients hospitalized with ischemic heart disease (IHD). METHODS: A descriptive cross-sectional design was used to enroll 517 patients at one Midwestern U.S. hospital. The State-Trait Hopelessness Scale measured hopelessness. RESULTS: State hopelessness was higher in ethnic minority patients compared to Whites. Ethnic minority patients who had never been married had higher state hopelessness than those who were married or separated/divorced. There were no differences in trait hopelessness. CONCLUSIONS: Ethnic minority patients with IHD, who have never been married, may be at higher risk for state hopelessness.

Evaluating the performance of gene-based tests of genetic association when testing for association between methylation and change in triglyceride levels at GAW20.

Although methylation data continues to rise in popularity, much is still unknown about how to best analyze methylation data in genome-wide analysis contexts. Given continuing interest in gene-based tests for next-generation sequencing data, we evaluated the performance of novel gene-based test statistics on simulated data from GAW20. Our analysis suggests that most of the gene-based tests are detecting real signals and maintaining the Type I error rate. The minimum p value and threshold-based tests performed well compared to single-marker tests in many cases, especially when the number of variants was relatively large with few true causal variants in the set.

Home- and Hospital-Based Cardiac Rehabilitation Exercise: The Important Role of Physician Recommendation.

Exercise reduces morbidity and mortality for patients with heart disease. Despite clear guidelines and known benefits, most cardiac patients do not meet current exercise recommendations. Physician endorsement positively affects patient participation in hospital-based Phase II cardiac rehabilitation programs, yet the importance of physician recommendation for home-based cardiac rehabilitation exercise is unknown. A prospective observational design was used to examine predictors of both home-based and Phase II rehabilitation exercise in a sample of 251 patients with coronary heart disease. Regression analyses were done to examine demographic and clinical characteristics, physical functioning, and patient's report of physician recommendation for exercise. Patients with a strong physician referral, who were married and older, were more likely to participate in Phase II exercise. Increased strength of physician recommendation was the unique predictor of home-based exercise. Further research is needed to examine how health professionals can motivate cardiac patients to exercise in home and outpatient settings.
