Background Heart failure (HF) is a prevalent chronic disease in older adults that requires extensive self-care to prevent decompensation and hospitalization. Cognitive impairment may impact the ability to perform HF self-care activities. We examined the association between cognitive impairment and adherence to self-care in patients hospitalized for acute HF. Design Prospective cohort study. Setting and participants A total of 577 patients (mean age = 71 years, 44% female) hospitalized for HF at five medical centers in the United States and Canada. Measurements and methods Participants were interviewed for information on self-reported adherence to self-care using the European Heart Failure Self-care Behaviour Scale. We assessed cognitive impairment in three domains (memory, processing speed, and executive function) using standardized measures. Patients’ demographic and clinical characteristics were obtained through medical record review. Multivariable linear regression was used to examine the association between cognitive impairment and self-care practices adjusting for demographic and clinical factors. Results A total of 453 patients (79%) were impaired in at least one cognitive domain. Average adherence to self-care activities among patients with global cognitive impairment did not differ significantly from those without cognitive impairment (30.5 versus 29.6; 45-point scale). However, impaired memory was associated with lower self-care scores (P = 0.006) in multivariable models. Conclusion Cognitive impairment is highly prevalent among older patients hospitalized for HF. Memory impairment is associated with poorer adherence to self-care practices. Screening for memory impairment in patients with HF may help to identify patients at risk for poor self-care who may benefit from tailored disease management programs.

Several prospective studies suggest that C‐reactive protein (CRP), a nonspecific serologic marker of inflammation, might be linked to risk of colorectal cancer (CRC), whereas others have reported null or protective effects. We analyzed data from 7,072 participants (50–85 years) in the U.S. National Health and Nutrition Examination Survey III (1988–1994), a nationally representative cohort (n = 33,994; 2 months–85 years) with vital status follow‐up to 2000. Hazard ratios (HRs) for mortality associated with baseline clinically raised (≥1.00 mg/dL) and intermediate (≥0.22–0.99 mg/dL) CRP levels were estimated using Cox proportional hazards regression controlling for CRC risk factors. There were 59 deaths from CRC, 106 from other obesity‐related cancers (other‐ORCs) and 1,130 from cardiovascular disease (CVD). Participants with clinically raised CRP at baseline were found to have a statistically significant greater risk of CRC death (HRs = 2.36–2.47) in comparison to persons with undetected levels. HRs were lower for death from other‐ORC and CVD (1.82, 95% CI 1.05–3.15; 1.53, 95% CI 1.29–1.81, respectively). Intermediate CRP level was associated with a nonsignificant 10–21% increased risk for CRC death. HR for CRC death was higher among persons with a normal BMI (2.16, 95% 0.96–4.87, p = 0.06) compared to those who were overweight (1.22, 95% CI 0.53–2.78) or obese (1.23, 95% CI, 0.37–4.08). A similar pattern was observed for waist circumference. This effect modification suggests that the impact of chronic inflammation may be independent of excess body fat. Future research is recommended to confirm emerging data that elevated serologic CRP might reflect underlying colonic inflammation.

Psychological Co-morbidities of Obesity

Sherry L. Pagoto; Kristin L. Schneider; Bradley M. Appelhans; Carol Curtin; Alexandra M. Hajduk

The association between obesity and psychological disorders has gained attention as the prevalence of obesity has rapidly increased in recent decades. Prevalence of obesity in people with psychological disorders has grown as fast or faster than in the general population (Am J Prev Med 36:341–350, 2009), which points to a growing health disparity in psychological-disordered populations. Not only are people with various psychological disorders disproportionately affected by obesity, but obesity appears to increase risk for various psychological disorders. The aim of this chapter is to provide a comprehensive overview of the associations between obesity and psychological disorders, potential mechanisms underlying these associations, and assessment and treatment of individuals with these comorbidities, including clinical challenges. Gaps in the research literature will be identified and recommendations for future made.

BACKGROUND Cognitive impairment is highly prevalent in patients with heart failure and is associated with adverse outcomes. However, whether specific cognitive abilities (eg, memory vs executive function) are impaired in heart failure has not been fully examined. We investigated the prevalence of impairment in 3 cognitive domains in patients hospitalized with acute decompensated heart failure (ADHF) and the associations of impairment with demographic and clinical characteristics. METHODS The sample included 744 patients hospitalized with ADHF (mean age 72 years, 46% female) at 5 medical centers. Impairment was assessed in 3 cognitive domains (memory, processing speed, executive function) using standardized measures. Demographic and clinical characteristics were obtained from a structured interview and medical record review. RESULTS A total of 593 (80%) of 744 patients were impaired in at least 1 cognitive domain; 32%, 31%, and 17% of patients were impaired in 1, 2, or all 3 cognitive domains, respectively. Patients impaired in more than 1 cognitive domain were significantly older, had less formal education, and had more noncardiac comorbidities (all P values < .05). In multivariable adjusted analyses, patients with older age and lower education had higher odds of impairment in 2 or more cognitive domains. Depressed patients had twice the odds of being impaired in all 3 cognitive domains (odds ratio 1.98, 95% CI 1.08-3.64). CONCLUSION Impairments in executive function, processing speed, and memory are common among patients hospitalized for ADHF. Recognition of these prevalent cognitive deficits is critical for the clinical management of these high-risk patients.

Background: Impairments in psychosocial status and cognition relate to poor clinical outcomes in patients with atrial fibrillation (AF). However, how often these conditions co-occur and associations between burden of psychosocial and cognitive impairment and quality of life (QoL) have not been systematically examined in patients with AF. Methods: A total of 218 patients with symptomatic AF were enrolled in a prospective study of AF and psychosocial factors between May 2013 and October 2014 at the University of Massachusetts Medical Center. Cognitive function, depression, and anxiety were assessed at baseline and AF-specific QoL was assessed 6 months after enrollment using validated instruments. Demographic and clinical information were obtained from a structured interview and medical record review. Results: The mean age of the study participants was 63.5 ± 10.2 years, 35% were male, and 81% had paroxysmal AF. Prevalences of impairment in 1, 2, and 3 psychosocial/cognitive domains (eg, depression, anxiety, or cognition) were 75 (34.4%), 51 (23.4%), and 16 (7.3%), respectively. Patients with co-occurring psychosocial/cognitive impairments (eg, >1 domain) were older, more likely to smoke, had less education, and were more likely to have heart failure (all P < 0.05). Compared with participants with no psychosocial/cognitive impairments, AF-specific QoL at 6 months was significantly poorer among participants with baseline impairment in 2 (B = −13.6, 95% CI: −21.7 to −5.4) or 3 (B = −15.1, 95% CI: −28.0 to −2.2) psychosocial/cognitive domains. Conclusion: Depression, anxiety, and impaired cognition were common in our cohort of patients with symptomatic AF and often co-occurred. Higher burden of psychosocial/cognitive impairment was associated with poorer AF-specific QoL.

Objective: To describe the prevalence and predictors of receipt of practical support among acute coronary syndrome (ACS) survivors during the early post-discharge period. Method: 406 ACS patients were interviewed about receipt of practical (instrumental and informational) support during the week after discharge. Demographic, clinical, functional, and psychosocial predictors of instrumental and informational practical support were examined. Results: 81% of participants reported receiving practical support during the early post-discharge period: 75% reported receipt of instrumental support and 51% reported receipt of informational support. Men were less likely to report receiving certain types of practical support, whereas married participants and those with higher education, impaired health literacy, impaired activities of daily living, and in-hospital complications were more likely to report receiving certain types of practical support. Conclusion: Receipt of practical support is very common among ACS survivors during the early post-discharge period, and type of support received differs according to patient characteristics.

Team science, defined as collaborative research efforts that leverage the expertise of diverse disciplines, is recognised as a critical means to address complex healthcare challenges, but the practical implementation of team science can be difficult. Our objective is to describe the barriers, solutions and lessons learned from our team science experience as applied to the complex and growing challenge of multiple chronic conditions (MCC). MCC is the presence of two or more chronic conditions that have a collective adverse effect on health status, function or quality of life, and that require complex healthcare management, decision-making or coordination. Due to the increasing impact on the United States society, MCC research has been identified as a high priority research area by multiple federal agencies. In response to this need, two national research entities, the Healthcare Systems Research Network (HCSRN) and the Claude D. Pepper Older Americans Independence Centers (OAIC), formed the Advancing Geriatrics Infrastructure and Network Growth (AGING) Initiative to build nationwide capacity for MCC team science. This article describes the structure, lessons learned and initial outcomes of the AGING Initiative. We call for funding mechanisms to sustain infrastructures that have demonstrated success in fostering team science and innovation in translating findings to policy change necessary to solve complex problems in healthcare.
