Factors Associated With Cognitive Impairment in Heart Failure With Preserved Ejection Fraction

Fletcher, J., Faulkner, K. M., Dickson, V. V. V., Fletcher, J., Katz, S. D., Chang, P. P. P., Gottesman, R. F., Witt, L. S., Shah, A. M., & D’Eramo Melkus, G. (Vols. 37, Issue 1, pp. 17-30).
Abstract
Abstract
Cognitive impairment is prevalent in heart failure and is associated with higher mortality rates. The mechanism behind cognitive impairment in heart failure with preserved ejection fraction (HFpEF) has not been established.

HIV Syndemic Factor Associations Among Adolescent Gay and Bisexual Men in the Youth Risk Behavior Survey 2015-2019: A Secondary Data Analysis

Fletcher, J., Garcia, D. R., Fletcher, J., Goldsamt, L., Bell, D. L., Zheng, Y., & Dunn Navarra, A.-M. M. (Vols. 34, Issues 5, pp. 440-458).
Abstract
Abstract
This analysis of the Youth Risk Behavior Survey examined HIV syndemic factor associations (substance use, violence, mental health, and HIV risk behaviors) among adolescent gay, bisexual, and other men who have sex with men-a population with the highest prevalence of undiagnosed HIV infections. The representative sample ( n = 644) exhibited low condom use (52%) and HIV testing (21%). Adjusted multivariate logistic regression models showed that Blacks were less likely to report HIV testing (adjusted odds ratio [aOR] = 0.06, 95% confidence interval [CI] [0.01-0.44], p < .01), whereas Hispanics were more likely to report four or more lifetime sexual partners (aOR = 3.75, 95% CI [1.49-9.44], p < .01), compared with Whites. A syndemic of substance use and intimate partner violence (sexual, sexual dating, and/or physical dating violence) was associated with early intercourse, multiple sexual partners, and drugs/alcohol before intercourse. Multiple syndemic factor exposures were associated with additive risk, suggesting multilevel approaches for HIV prevention.

The Impact of an Electronic Best Practice Advisory on Patients' Physical Activity and Cardiovascular Risk Profile

Fletcher, J., McCarthy, M. M., Szerencsy, A., Fletcher, J., Taza-Rocano, L., Weintraub, H., Hopkins, S., Applebaum, R., Schwartzbard, A., Mann, D., D’Eramo Melkus, G., Vorderstrasse, A., & Katz, S. D. (Vols. 39, Issues 5, pp. E150-E157).
Abstract
Abstract
Regular physical activity (PA) is a component of cardiovascular health and is associated with a lower risk of cardiovascular disease (CVD). However, only about half of US adults achieved the current PA recommendations.

Nurse-Reported Staffing Guidelines and Exclusive Breast Milk Feeding

Fletcher, J., Lyndon, A., Simpson, K. R., Spetz, J., Zhong, J., Gay, C. L., Fletcher, J., & Landstrom, G. L. (Vols. 71, Issues 6, pp. 432-440).
Abstract
Abstract
Nursing care is essential to overall quality of healthcare experienced by patients and families-especially during childbearing. However, evidence regarding quality of nursing care during labor and birth is lacking, and established nurse-sensitive outcome indicators have limited applicability to maternity care. Nurse-sensitive outcomes need to be established for maternity care, and prior research suggests that the initiation of human milk feeding during childbirth hospitalization is a potentially nurse-sensitive outcome.

Psychometric Testing of the Self-care of Hypertension Inventory Version 3.0

Fletcher, J., Dickson, V. V. V., Fletcher, J., & Riegel, B. (Vols. 36, Issues 5, pp. 411-419).
Abstract
Abstract
In this updated Self-care of Hypertension Inventory Version 3.0 (SC-HI v3.0), items were added to better reflect the Theory of Self-care of Chronic Illness and revised based on recent research. The reorganized and expanded SC-HI now reflects the theoretical concepts of self-care maintenance, monitoring, and management.

School-Based Protective Factors for HIV Prevention in the United States: Secondary Analysis of the Youth Risk Behavior Survey 2015-2019

Fletcher, J., Garcia, D. R., Fletcher, J., Goldsamt, L., Bell, D. L., Zheng, Y., & Dunn Navarra, A.-M. M. (Vols. 36, Issue 1, pp. 54-68).
Abstract
Abstract
This secondary analysis of the National Youth Risk Behavior Survey (years 2015-2019) examines associations between school-based protective factors (i.e., safe school environments and academic achievement) and HIV risk behaviors among sexually experienced adolescent gay and bisexual men ( n = 644), a population with the highest prevalence of undiagnosed HIV infections. Demographics included Hispanics/Latinos (25%, n = 158), Other race/ethnicity (14%, n = 88), and non-Hispanic Blacks/African Americans (13%, n = 81). Adjusted models showed that protective factors reduced odds for early sexual debut, multiple sexual partners, sex under the influence of drugs/alcohol, and condomless sex, with an additive effect demonstrated when two protective factors were present. Hispanics/Latinos had greater odds of reporting multiple sexual partners and HIV testing, indicating opportunities for school-based HIV prevention and further research. Our findings provide support for school-based programs that aim to improve social and structural determinants of health and ultimately reduce adolescent HIV burdens.
