RESUMO
BACKGROUND: Predictors have not been determined of serum brain-derived neurotrophic factor (BDNF) levels among patients with heart failure (HF). OBJECTIVE: The primary purpose was to evaluate history of atrial fibrillation, age, gender, and left ventricular ejection fraction as predictors of serum BDNF levels at baseline, 10 weeks, and 4 and 8 months after baseline among patients with HF. METHODS: This study was a retrospective cohort analyses of 241 patients with HF. Data were retrieved from the patients' health records (coded history of atrial fibrillation, left ventricular ejection fraction), self-report (age, gender), and serum BDNF. Linear multiple regression analyses were conducted. RESULTS: One hundred three patients (42.7%) had a history of atrial fibrillation. History of atrial fibrillation was a significant predictor of serum BDNF levels at baseline (ß = -0.16, P = .016), 4 months (ß = -0.21, P = .005), and 8 months (ß = -0.19, P = .015). Older age was a significant predictor at 10 weeks (ß = -0.17, P = .017) and 4 months (ß = -0.15, P = .046). CONCLUSIONS: Prospective studies are needed to validate these results. Clinicians need to assess patients with HF for atrial fibrillation and include treatment of it in management plans.
RESUMO
BACKGROUND: Cognitive dysfunction predicts mortality in heart failure (HF). Computerized cognitive training (CCT) has shown preliminary efficacy in improving cognitive function. However, the relationship between CCT and mortality is unclear. Aims were to evaluate (1) long-term efficacy of CCT in reducing 24-month mortality and (2) age, HF severity, global cognition, memory, working memory, depressive symptoms, and health-related quality of life as predictors of 24-month mortality among patients with HF. METHODS: In this prospective longitudinal study, 142 patients enrolled in a 3-arm randomized controlled trial were followed for 24 months. Logistic regression was used to achieve the aims. RESULTS: Across 24 months, 16 patients died (CCT, 8.3%; control groups, 12.8%). Computerized cognitive training did not predict 24-month mortality (odds ratio [OR], 0.65). Older age (OR, 1.08), worse global cognition (OR, 0.73), memory (OR, 0.81), and depressive symptoms (OR, 1.10) at baseline predicted 24-month mortality. CONCLUSIONS: Efficacious interventions are needed to improve global cognition, memory, and depressive symptoms and reduce mortality in HF.

Although research has largely focused on the effects of physical activity (PA) on the brain, less is known about the influence of the brain on engagement in healthy-living behaviors, such as regular PA. In this secondary analysis of a study of brain activity and participation in healthy-living behaviors, we examined relationships between the activation of selected brain networks and PA in persons self-managing chronic conditions. Fifty-eight individuals with chronic conditions underwent functional magnetic resonance imaging while exposed to a protocol consisting of listening to emotion-focused and analytic-focused information and measures of activation of three neuromarkers were obtained: default mode network (DMN), task-positive network (TPN), and ventromedial prefrontal cortex (vmPFC). In an exploratory analysis, we assessed differences in neuromarker activation between two PA levels (representing higher and lower accelerometry-measured PA levels) of 1) moderate-to-vigorous physical activity (MVPA) minutes, 2) metabolic equivalents expended (METs), and 3) daily steps. Results showed positive associations between MVPA and DMN (r = 0.31, P = 0.018), steps and DMN (r = 0.28, P = 0.035), and MVPA and vmPFC (r = 0.29, P = 0.026). No associations were found between the TPN and any of the PA measures. Individuals with high MVPA and METs had higher DMN values compared with those with low MVPA (t = -2.17, P = 0.035) and METs (t = -2.02, P = 0.048). No differences in TPN and vmPFC were found among PA levels. These results suggest that providing health information that activates the emotion-focused brain network may be more useful than analytic-focused information (centered on logic and reasoning) to assist people with chronic conditions to engage in more PA.NEW & NOTEWORTHY The influence of the brain on engagement in regular physical activity (PA) has not been well studied. We examined relationships between the activation of three neuromarkers and two PA levels in 58 persons self-managing chronic conditions. Findings suggest that individuals who optimally process health-information when the emotional tone is high (Empathic Network; DMN) may engage in more PA compared with individuals who respond to health information when the emotional tone is low (Analytic Network; TPN).

BACKGROUND: Precautions to mitigate spread of COVID-19 such as the closing of exercise facilities impacted physical activity behaviors. Varied risks for severe COVID-19 may have influenced participation in regular physical activity to maintain precautions. OBJECTIVE: Describe differences in the amount and intensity of physical activity between adults at high versus low risk for severe COVID-19 illness during the pandemic. We hypothesized that over 13 months, 1) high-risk adults would have greater odds of inactivity than low-risk adults, and 2) when active, high-risk adults would have lower metabolic equivalent of task minutes (MET-min) than low-risk adults. METHODS: This longitudinal observational cohort study surveyed U.S. adults' demographics, health history, and physical activity beginning March 2020 using REDCap. Using self-report, health history was assessed with a modified Charlson Comorbidity Index and physical activity with the International Physical Activity Questionnaire. Repeated physical activity measurements were conducted in June, July, October, and December of 2020, and in April of 2021. Two models, a logistic model evaluating physical inactivity (hypothesis 1) and a gamma model evaluating total MET-min for physically active individuals (hypothesis 2), were used. Models were controlled for age, gender, and race. RESULTS: The final sample consisted of 640 participants (mean age 42.7 ± 15.7, 78% women, 90% white), with n = 175 categorized as high-risk and n = 465 as low-risk. The odds of inactivity for the high-risk adults were 2.8 to 4.1 times as high than for low-risk adults at baseline and 13 months. Active high-risk adults had lower MET-min levels than low-risk adults in March (28%, p = 0.001), June (29%, p = 0.002), and July of 2020 (30%, p = 0.005) only. CONCLUSIONS: Adults at high risk of severe COVID-19 illness were disproportionately more likely to be physically inactive and exhibit lower MET-min levels than adults at low risk during the early months of the COVID-19 pandemic.

BACKGROUND: Depressive symptoms, brain-derived neurotrophic factor (BDNF) Val66Met, and apolipoprotein (APOE)-ε4 may moderate response to computerized cognitive training (CCT) interventions among patients with heart failure (HF). OBJECTIVES: The purpose of this study was to examine moderators of intervention response to CCT over 8 months among patients with HF enrolled in a 3-arm randomized controlled trial. Outcomes were memory, serum BDNF, working memory, instrumental activities of daily living (IADLs), and health-related quality of life (HRQL). METHODS: 256 patients with HF were randomized to CCT, computerized crossword puzzles active control, and usual care control groups for 8 weeks. Data were collected at enrollment, baseline, 10 weeks, and 4 and 8 months. Mixed effects models were computed to evaluate moderators. RESULTS: As previously reported, there were no statistically significant group by time effects in outcomes among the 3 groups over 8 months. Tests of moderation indicated that depressive symptoms and presence of BDNF Val66Met and APOE-ε4 were not statistically significant moderators of intervention response in outcomes of delayed recall memory, serum BDNF, working memory, IADLs, and HRQL. In post hoc analysis evaluating baseline global cognitive function, gender, age, and HF severity as moderators, no significant effects were found. HF severity was imbalanced among groups (P = .049) which may have influenced results. CONCLUSIONS: Studies are needed to elucidate biological mechanisms of cognitive dysfunction in HF and test novel interventions to improve memory, serum BDNF, working memory, IADLs and HRQL. Patients may need to be stratified or randomized by HF severity within intervention trials.

BACKGROUND: More than 1 million individuals undergo cardiothoracic surgery for coronary artery bypass graft or valve repair/replacement annually in the United States. There is an increased risk of developing serious cognitive impairment post cardiothoracic surgery. Pharmacological interventions and surgical techniques were associated with improvements in cognitive function in previous systematic reviews. However, a gap in the literature exists regarding how nonpharmacological interventions can mitigate cognitive impairment in adults undergoing cardiac surgery. OBJECTIVE: The aim of this study was to explore the effectiveness of nonpharmacological interventions to reduce the detrimental effects of cardiac surgery on cognitive function in patients after cardiothoracic surgery. METHODS: CINAHL, MEDLINE, PubMed, EMBASE, PsycINFO, and Web of Science databases were searched following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines from January 2011 to February 2022. RESULTS: Nineteen studies were included in this review. Researchers defined cognitive impairment differently across studies. Various interventions were used to reduce cognitive impairment post cardiothoracic surgery, with the most common being remote ischemic limb conditioning. The interventions used to reduce cognitive impairment were heterogeneous in outcomes, measurements, and time of assessment, but only 2 interventions were associated with a reduction in cognitive impairment. CONCLUSIONS: This review is a unique synthesis of the quality of interventions that address broader components of cognition. Researchers used various interventions to reduce cognitive impairment; the outcomes, instruments, and time interval for measurements were heterogeneous. Researchers should conduct future studies at multiple time intervals, using a comprehensive measure of cognitive impairment to better understand the impact of cognitive impairment interventions postoperatively.
RESUMO
OBJECTIVES: In three chronic illness populations and in a combined sample, we assessed differences in two algorithms to determine wear time (WT%) and four algorithms to determine: Kilocalories, light physical activity (PA), moderate-to-vigorous PA (MVPA), and metabolic equivalents (METs). METHODS: Data were collected from 29 people living with HIV (PLHIV), 27 participants recovering from a cardiac event, and 15 participants with hypertension (HTN). Participants wore the ActiGraphTM wGT3X-BT for > 3 days on their hip. Analysis of variance (ANOVA) was used to assess differences among the algorithms. RESULTS: No differences were found between the two algorithms to assess WT% or among the four algorithms to assess kilocalories in each of the chronic illness populations or in the combined sample. Significant differences were found among the four algorithms for light PA (p < .001) and METs (p < .001) in each chronic illness population and in the combined sample. MVPA was significantly different among the four algorithms in the PLHIV (p = .007) and in the combined sample (p < .001), but not in the cardiac (p = .064) or HTN samples (p = .200). DISCUSSION: Our findings indicate that the choice of algorithm does make a difference in PA determination. Differences in algorithms should be considered when comparing PA across different chronic illness populations.

BACKGROUND: The objective of this 3-arm randomized controlled trial was to evaluate the efficacy of computerized cognitive training (CCT) in improving primary outcomes of delayed-recall memory and serum brain-derived neurotrophic factor (BDNF) levels; and the secondary outcomes were working memory, instrumental activities of daily living (IADLs) and health-related quality of life (HRQL) in patients with heart failure (HF). METHODS AND RESULTS: Patients (nâ¯=â¯256) were randomly assigned to 8 weeks of CCT using BrainHQ, computerized crossword puzzles active control intervention, and usual care. All patients received weekly nurse-enhancement interventions. Data were collected at enrollment and baseline visits and at 10 weeks and 4 and 8 months. In mixed effects models, there were no statistically significant group or group-by-time differences in outcomes. There were statistically significant differences over time in all outcomes in all groups. Patients improved over time on measures of delayed-recall memory, working memory, IADLs, and HRQL and had decreased serum BDNF. CONCLUSIONS: CCT did not improve outcomes compared with the active control intervention and usual care. Nurse-enhancement interventions may have led to improved outcomes over time. Future studies are needed to test nurse-enhancement interventions in combination with other cognitive interventions to improve memory in persons with HF.

BACKGROUND: For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts. OBJECTIVE: The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery. METHODS: Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy. RESULTS: There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08). CONCLUSIONS: Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

BACKGROUND: Associations among illness perceptions of viruses, anxiety and depression symptoms, and self-management decisions, such as mask-wearing, are critical to informing public health practices to mitigate the short- and long-term consequences of the SARS-CoV-2 viral pandemic. PURPOSE: Guided by the common-sense model of self-regulation, this observational study examined associations among illness perceptions of COVID-19, anxiety, and depression symptoms among community-dwelling adults. METHOD: Data were collected from 1380 adults living in the United States early in the pandemic (03-23-2020 to 06-02-2020). Participants completed online surveys. Analyses were conducted using descriptive statistics and correlations. FINDINGS: While increased anxiety symptoms were associated with less perceived personal control, greater concern, and higher emotional responsiveness, increased depression symptoms were related to lower concern as well as greater emotional responsiveness and perceived consequences of the pandemic. DISCUSSION: Associations among illness perceptions, anxiety, and depression symptoms may impact viral spread mitigation behavior adoption.

Deaths from COVID-19 continue to rise, and this virus has asymmetric impacts on marginalized communities though specific impacts on sexual and gender minority communities are not well understood. From March 23 to June 20, 2020, in an online cross-sectional survey among 1380 US adults, we assessed physical symptoms, psychological symptoms, rumination, and perceived social support in order to describe differences between sexual and gender minority (n = 290) and cisgender heterosexual (n = 1090) respondents. Sexual and gender minority respondents had more frequent COVID-19-associated physical symptoms and depression and anxiety symptoms. Sexual and gender minorities had a significantly higher proportion of depression and anxiety scores exceeding the clinical concern threshold. Longitudinal studies on the physical and psychological impacts of COVID-19 among sexual and gender minority communities are needed to inform interventions to eliminate these disparities.

Cardiac rehabilitation is important to improve physical activity and reduce cardiovascular disease risk factors among people who have experienced a major cardiac event. However, poor emotion regulation can make it difficult to change cardiovascular risk factors. The purpose of this article was to assess the feasibility of the Regulating Emotions to improve Nutrition Exercise and reduce Stress (RENEwS) intervention, an education program aimed at improving emotion regulation strategies among patients in cardiac rehabilitation. A total of 14 cardiac rehabilitation patients (mean age 61 years) enrolled in five weekly RENEwS sessions. Qualitative analysis of participants' comments was used to assess eight elements of feasibility. In total 57% of participants completed the intervention. Participants thought the intervention was feasible, with strengths in the areas of acceptability, demand, adaptation, integration, and implementation. Other comments regarding practicality, expansion, and perceived efficacy provide guidance for intervention refinement.

PURPOSE: This study aims to determine (1) if depressive symptoms in the year following completion of cardiac rehabilitation impact physical functional capacity and (2) if exercise, perceived benefits and barriers, self-efficacy, and social support moderate this relationship. DESIGN: This longitudinal correlational secondary data analysis included 379 cardiovascular rehabilitation patients. METHODS: Participants completed measures of depression and potential moderating variables at baseline, 2 months, 6 months, and 12 months and 6-minute work test at baseline and 12 months and wore heart rate monitors to measure exercise for 12 months. FINDINGS: Poorer physical functional capacity was predicted by depressed mood score. This relationship was moderated by the percentage of time exercising in target heart rate zone and family support of exercise, but not by perceived benefits and barriers or self-efficacy for exercise. CONCLUSIONS: Depressive symptoms negatively impact physical functional capacity, and this relationship is moderated by family support and the percentage of time exercising in target heart rate zone. CLINICAL RELEVANCE: Improving percentage of time exercising in target heart rate zone may be a mechanism by which patients with depressed mood can optimize physical functional capacity.

As the nursing faculty shortage persists, there is an urgent need to develop emerging nurse scholars into research leaders capable of advocating for the profession and expanding on the mission to improve health. To address this need, the Midwest Nursing Research Society (MNRS) commissioned a student task force that led to the development of the Emerging Scholars Network (ESN). The purpose of this article is to describe how the ESN was developed, integrated, and promoted within the MNRS to advance the overall mission and sustainability of the society. The establishment and success of the ESN is described using the Five Developmental Stages of Organization Evolution. These stages include the following: (a) Developing a Concept; (b) Launching a Start-Up; (c) Establishing Credibility; (d) Creating Sustainability; and (e) Road to Maturing and Legacy. Recommendations for continued development of the ESN are provided.

BACKGROUND: The rising number of patients with a left ventricular assist device (LVAD) require care management to successfully transition home after implantation. These patients and their families need to manage their heart failure, and the complexities of an LVAD and the associated lifestyle modifications. Translating knowledge of transitional care interventions in patients with chronic diseases to those with an LVAD may provide valuable insight. To help inform the furthering of care transitions in the LVAD patient population, an integrative review was conducted. AIM: The aim of this review was to explore the transitions of care interventions of care in patients and its potential for application in the destination therapy LVAD. METHODS: This integrative review was guided by the Whittemore and Knafl's methodology. RESULTS: A total of 12 articles from 264 retrieved articles met inclusion criteria and were included in the literature review. DISCUSSION: This review identified that evidence-based transitional care interventions have been shown to decrease avoidable rehospitalization, the associated costs, and improve quality of life when compared to usual care. IMPLICATIONS FOR PRACTICE: A common feature of transitional care interventions is the inclusion of nurse leadership. Nurses should be prepared to participate in transitional care interventions to optimally improve outcomes for patients with heart failure and potentially those with an LVAD. Additionally, to make transitional care interventions more effective they should be implemented with moderate intensity or greater. CONCLUSION: This review provided information supporting the trialing of transitional care interventions in patients with an LVAD and suggests pilot research to optimize interventions for this population.

BACKGROUND AND PURPOSE: Emotion regulation, the experiencing, processing, and modulating of emotional response, is necessary to manage the emotional stressors common in patients with chronic illness. Overwhelming emotional demands deplete the resources needed for everyday self-care management of chronic disease, contributing to poor health outcomes. Emotion regulation is shown to impact behaviors in healthy individuals; yet, a review of literature examining evidence of associations in chronically ill populations is lacking. The purpose of this article is to examine the state of the science relative to the impact of emotion regulation on health outcomes in chronic illness populations. METHODS: Articles were reviewed (N = 14) that focused on emotion regulation and outcomes of patients with chronic illness. RESULTS: Indicate that most of the studies focused on these concepts are cross-sectional and measure emotion regulation using various surveys. Potential relationships exist with increased age, male gender, higher education, decreased stress, depressive, and anxiety symptoms being associated with more adaptive emotion regulation. Of primary importance to patients with chronic illnesses is the potential link between greater difficulties with emotion regulation and the presence of chronic disease as well as poorer physical function. IMPLICATIONS FOR PRACTICE: Care should include attention to affective regulation as well as physiologic responses of chronic illness.

BACKGROUND: African American women with heart failure (HF) have stressors that negatively impact HF self-management adherence and heighten the occurrence of negative cardiac health events. Perceptions of illness coherence and controllability and emotion regulation are known to facilitate self-management in the face of stressors. OBJECTIVE: The aim of this study was to determine whether difficulties with emotion regulation and negative perceptions of illness coherence and controllability are detrimental to adherence and increase negative cardiac health events in this patient population. METHODS: African American women (n = 54) with HF, aged 49 to 84 years, participated in this longitudinal descriptive correlational study. Using convenience sampling, we recruited patients from hospitals and HF clinics. They completed interviews at intake and 30 days, and their medical records were reviewed at 90 days. Linear and logistic regression models were used to assess predictors of general adherence and negative cardiac health events. RESULTS: Of 54 patients who participated in the study, 28 experienced a negative health event during 90 days, and 57% of these events were cardiac related. The only clear predictor of these events was greater New York Heart Association functional classification (ß = 1.47, P = .027). No associations were found between predictors (emotion regulation, controllability, coherence, age, education) and general adherence. CONCLUSIONS: Emotion regulation showed a possible greater impact on negative cardiac health events than on general adherence. Perceived illness coherence showed less impact on negative cardiac health events than on general adherence.

Health care disparities associated with African American race may influence event-free survival in patients with heart failure (HF). A secondary data analysis included 863 outpatients enrolled in a multicenter HF registry. Cox regression was used to determine whether African American race was associated with shorter HF event-free survival after controlling for covariates. The multivariable-adjusted hazard ratios (95% confidence intervals [CI]) of older age (1.03, 95% CI = [1.01, 1.04]), New York Heart Association (NYHA) functional class (1.73, 95% CI = [1.29, 2.31]), depressive symptoms (1.05, 95% CI = [1.02, 1.07]), and African American race (1.64, 95% CI = [1.01, 2.68]) were predictors of shorter event-free survival (all ps < .05). Comparisons showed that NYHA functional class was predictive of shorter event-free survival in Caucasians (1.81, 95% CI = [1.33, 2.46]) but not in African Americans (1.24, 95% CI = [.40, 3.81]). African Americans with HF experienced a disparate risk of shorter event-free survival not explained by a variety of risk factors.
