Exploring the "Obesity Paradox" as a Correlate of Cognitive and Physical Function in Community-dwelling Black and White Older Adults.

Objective: The obesity paradox has been documented in aged populations, yet it remains unclear if this paradox persists for physical and cognitive outcomes in community-dwelling older adult populations. Our study examines associations between body mass index (BMI) classification, cognitive function, and physical function. We also investigate whether these associations are modified by race or age.

Fatigue in Older Adults Postmyocardial Infarction.

Objective: The purpose of this study was to comprehensively examine putative factors that may independently contribute to fatigue and subsequent persistence of fatigue in elderly adults 6-8 months post-myocardial infarction (MI). Studies suggest cardiac function, comorbidities, daytime sleepiness, depression, anemia, interleukins, and social support are correlates of fatigue; however, no studies have systematically examined these factors 6 months post-MI in an aging population.

Methods: Study participants included 49 women and men (N = 98) ages 65-91 who were 6-8 months post-MI.

Predicting Heart Failure Readmissions.

Objectives: In this study, the effects of sociodemographic and clinical factors on heart failure (HF) readmission risk were examined.

Background: Hospitals now incur financial penalties for excessive HF readmission rates; therefore, identifying factors associated with risk is essential for designing risk-reduction strategies.

Methods: A retrospective cohort study using chart reviews compared HF inpatients (N = 245) who were readmitted with those who were not readmitted.

Evaluation of concept mapping in an associate degree nursing program.

The purpose of this project was to evaluate concept mapping as a clinical teaching-learning activity that reflects critical thinking by promoting identification of nonlinear relationships among the components of the nursing process. The sample involved 28 associate degree nursing students from one graduating class. Students completed one map each in the second and fourth semesters and two maps in the fifth semester, for a total of four concept maps.
