Associations of Insomnia Symptoms With Cognition in Persons With Heart Failure

Gharzeddine, R., Yu, G., McCarthy, M. M., & Dickson, V. V. (2021). Western Journal of Nursing Research. 10.1177/0193945920988840
Abstract
Abstract
Although cognitive impairment is common among persons with heart failure and negatively impacts self-care, hospitalization, and mortality, the associations between cognitive impairment and insomnia symptoms are not clearly understood. The purpose of this study was to explore these associations and examine if they are maintained after adjusting for relevant sociodemographic, clinical, and lifestyle factors. Guided by the Neurocognitive model of insomnia and sleep and the self-care conceptual model, a cross-sectional data analysis using parametric testing was conducted on the Health and Retirement Study wave 2016. Difficulty initiating sleep and early morning awakening, but not difficulty maintaining sleep were significantly associated with poorer cognitive performance in the bivariate and multivariate analysis. Our results are suggestive of different phenotypes of insomnia symptoms that may have different associations with cognition in persons with heart failure. Further research using objective measurements of insomnia symptoms and detailed neuropsychiatric testing of cognition is needed to confirm this conclusion.

Implementing the physical activity vital sign in an academic preventive cardiology clinic

McCarthy, M. M., Fletcher, J., Heffron, S., Szerencsy, A., Mann, D., & Vorderstrasse, A. (2021). Preventive Medicine Reports, 23. 10.1016/j.pmedr.2021.101435
Abstract
Abstract
The aims were to implement physical activity (PA) screening as part of the electronic kiosk check-in process in an adult preventive cardiology clinic and assess factors related to patients’ self-reported PA. The 3-question physical activity vital sign (PAVS) was embedded in the Epic electronic medical record and included how many days, minutes and intensity (light, moderate, vigorous) of PA patients conducted on average. This is a data analysis of PAVS data over a 60-day period. We conducted multivariable logistic regression to identify factors associated with not meeting current PA recommendations. Over 60 days, a total of 1322 patients checked into the clinic using the kiosk and 72% (n = 951) completed the PAVS at the kiosk. The majority of those patients were male (58%) and White (71%) with a mean age of 64 ± 15 years. Of the 951 patients completing the PAVS, 10% reported no PA, 55% reported some PA, and 35% reported achieving at least 150 min moderate or 75 min vigorous PA/week. In the logistic model, females (AOR = 1.4, 95%CI: 1.002–1.8, p =.049) vs. males, being Black (AOR = 2.0, 95%CI: 1.04–3.7, p =.038) or ‘Other’ race (AOR = 1.5, 95%CI: 1.02–2.3, p =.035) vs. White, unknown or other types of relationships (AOR = 0.0.26, 95%CI: 0.10–0.68, p =.006) vs. being married/partnered, and those who were retired (AOR = 1.9, 95% CI: 1.4–2.8, p <.001) or unemployed (AOR = 2.2, 95%CI: 1.3–3.7, p =.002) vs. full-time workers were associated with not achieving recommended levels of PA. The PAVS is a feasible electronic tool for quickly assessing PA and may prompt providers to counsel on this CVD risk factor.

Insomnia and Insomnia Symptoms in Persons with Heart Failure: An Integrative Review

Gharzeddine, R., McCarthy, M. M., Yu, G., & Vaughan Dickson, V. (2021). Journal of Cardiovascular Nursing, 36(4), 374-384. 10.1097/JCN.0000000000000719
Abstract
Abstract
Background/Objective Insomnia and insomnia symptoms are highly prevalent in persons with heart failure (HF), and they are associated with several untoward outcomes. The purpose of this integrative review is to describe the correlates, predictors, and outcomes of insomnia and insomnia symptoms in persons with HF. Methods Using integrative review methods, an extensive electronic search of 5 databases was conducted for the period of 2000-2019. Sixteen studies were identified that met the inclusion criteria for review and investigated insomnia or insomnia symptoms in HF. Results Various sociodemographic factors, chronic comorbidities, clinical factors, and cognitive-behavioral factors are correlates and predictors of insomnia and insomnia symptoms in persons with HF. Depression, fatigue, daytime sleepiness, poor self-reported physical functioning, decreased exercise capacity, cardiac events, and poor health-related quality of life are significant outcomes of insomnia and insomnia symptoms in persons with HF. The associations of insomnia and insomnia symptoms with age, sex, sleep-disordered breathing, and cognition were not consistent across all studies. Conclusion Larger studies with diverse age and race groups as well as longitudinal studies and designs that test mediation effects are needed to disentangle complex relationships between insomnia and insomnia symptoms and several of their potential predictors and correlates in HF.

Managing Diabetes in the Workplace

McCarthy, M., Vorderstrasse, A., Yan, J., Portillo, A., & Dickson, V. V. (2021). Workplace Health and Safety, 69(5), 216-223. 10.1177/2165079920965538
Abstract
Abstract
Background: Although many adults with diabetes are productive members of the workforce, loss of work productivity has been associated with diabetes. The purpose of this study was to explore the interrelationship between work-related factors and current work ability in adults with type 1 diabetes (T1D) and type 2 diabetes (T2D). Methods: This study used a convergent mixed-method design. We assessed the relationship between work-related factors and work ability using bivariate statistics and logistic regression. Work ability was measured using the Work Ability Index and Karasek’s Job Content Questionnaire (JCQ) was employed to measure job demands. Qualitative interviews (n = 30) explored the relationship between diabetes and work. Findings: The sample (n =101) was mostly female (65%) and White (74%). Most worked full-time (65%), had T2D (87%), an elevated glycated hemoglobin A1c ≥ 7% (56%), and were overweight (22%) or obese (68%). Only 33% of subjects self-reported their work ability as excellent. Four of the JCQ subscales (skill discretion, psychological demands, supervisor support, and coworker support), and work–life balance were significantly associated with work ability (all p <.05). In adjusted models, better coworker support (OR = 1.4; 95% CI = [1.04, 1.9]) and better work–life balance (OR = 1.3; 95% CI = [1.1, 1.5]) were associated with excellent work ability. Many stated their diabetes impacted them at work and spoke of the effects of stress. Few engaged in workplace wellness programs. Conclusion/Application to Practice: Social support and work–life balance were associated with excellent work ability. Engaging workers with diabetes in workplace educational programs may take strategic efforts by occupational health staff.

The Experience of Partners of Adults with Type 1 Diabetes: an Integrative Review

Whittemore, R., Delvy, R., & McCarthy, M. M. (2018). Current Diabetes Reports, 18(4). 10.1007/s11892-018-0986-4
Abstract
Abstract
Purpose of Review: The purpose of this review was to synthesize the research on the experience of partners living with adults with type 1 diabetes (T1D). Recent Findings: Eleven studies were included in the review. Three themes on the experience of living with a person with T1D were identified: the undercurrent of hypoglycemia, partners’ involvement in diabetes care, and the impact on partners’ lives. Due to considerable fear of hypoglycemia, partners had pervasive and deliberate ways in which they made attempts to minimize hypoglycemia in the person with diabetes and its cascade to a health emergency. As a result, partners of adults with T1D experienced considerable distress and disrupted lives. Partners also expressed a need for more support from family, friends, and health professionals. Summary: Research is needed on the partner experience across the lifespan and the specific supportive services they need in order to optimize their health outcomes.

Type 1 Diabetes Self-Management From Emerging Adulthood Through Older Adulthood

McCarthy, M. M., & Grey, M. (2018). Diabetes Care. 10.2337/dc17-2597
Abstract
Abstract
OBJECTIVE: The purpose of this study of adults with type 1 diabetes was to analyze patterns of diabetes self-management behaviors and predictors of glycemic control across the adult life span.RESEARCH DESIGN AND METHODS: This study was a secondary cross-sectional analysis of data from of 7,153 adults enrolled in the Type 1 Diabetes Exchange clinic registry who were divided into four developmental stages (emerging, young, middle-aged, and older adults). Data were collected by questionnaire and medical record review at enrollment. Statistical analyses compared sociodemographic, clinical, and diabetes-related factors across groups. Logistic regressions were conducted for each group to identify factors associated with hemoglobin A1c ≥7%.RESULTS: The sample was divided according to adult developmental stage: emerging adults, age 18 to <25 years (n = 2,478 [35%]); young adults, age 25 to <45 years (n = 2,274 [32%]); middle-aged adults, age 45 to <65 years (n = 1,868 [26%]; and older adults, age ≥65 years (n = 533 [7%]). Emerging adults had the highest mean hemoglobin A1c level (8.4 ± 1.7% [68 mmol/mol]), whereas older adults had the lowest level (7.3 ± 0.97% [56 mmol/mol]; P < 0.0001). Emerging adults were less likely to use an insulin pump (56%) or a continuous glucose monitor (7%), but were more likely to miss at least one insulin dose per day (3%) and have had an episode of diabetic ketoacidosis in the past year (7%) (all P < 0.0001). Different factors were associated with hemoglobin A1c ≥7% in each age group, but two factors were noted across several groups: the frequency of blood glucose checks and missed insulin doses.CONCLUSIONS: When discussing diabetes self-management, providers may consider a patient's developmental stage, with its competing demands, such as work and family; psychosocial adjustments; and the potential burden of comorbidities.
