AGS and NIA bench-to bedside conference summary: Cancer and cardiovascular disease

Mohile, Supriya; Blaum, Caroline S; Abadir, Peter M; Dale, William; Forman, Daniel E; Fung, Chunkit; Holmes, Holly M; Moslehi, Javid; Mustian, Karen M; Rich, Michael W; Whitson, Heather E
This report summarizes the presentations, discussions, and recommendations of the most recent American Geriatrics Society and National Institute on Aging research conference, "Cancer and Cardiovascular Disease," on October 18-19, 2021. The purpose of this virtual meeting was to address the interface between cancer and heart disease, which are the two leading causes of death among older Americans. Age-related physiologic changes are implicated in the pathogenesis of both conditions. Emerging data suggest that cancer-related cardiovascular disease (CVD) involves disrupted cell signaling and cellular senescence. The risk factors for CVD are also risk factors for cancer and an increased likelihood of cancer death, and people who have both cancer and CVD do more poorly than those who have only cancer or only CVD. Issues addressed in this bench-to-bedside conference include mechanisms of cancer and CVD co-development in older adults, cardiotoxic effects of cancer therapy, and management of comorbid cancer and CVD. Presenters discussed approaches to ensure equitable access to clinical trials and health care for diverse populations of adults with CVD and cancer, mechanisms of cancer therapy cardiotoxicity, and management of comorbid CVD and cancer, including the role of patient values and preferences in treatment decisions. Workshop participants identified many research gaps and questions that could lead to an enhanced understanding of comorbid CVD and cancer and to better and more equitable management strategies.

Associations of Age at Diagnosis and Duration of Diabetes With Morbidity and Mortality Among Older Adults

Cigolle, Christine T; Blaum, Caroline S; Lyu, Chen; Ha, Jinkyung; Kabeto, Mohammed; Zhong, Judy
Importance/UNASSIGNED:Older adults vary widely in age at diagnosis and duration of type 2 diabetes, but treatment often ignores this heterogeneity. Objectives/UNASSIGNED:To investigate the associations of diabetes vs no diabetes, age at diagnosis, and diabetes duration with negative health outcomes in people 50 years and older. Design, Setting, and Participants/UNASSIGNED:This cohort study included participants in the 1995 through 2018 waves of the Health and Retirement Study (HRS), a population-based, biennial longitudinal health interview survey of older adults in the US. The study sample included adults 50 years or older (n = 36 060) without diabetes at entry. Data were analyzed from June 1, 2021, to July 31, 2022. Exposures/UNASSIGNED:The presence of diabetes, specifically the age at diabetes diagnosis, was the main exposure of the study. Age at diagnosis was defined as the age when the respondent first reported diabetes. Adults who developed diabetes were classified into 3 age-at-diagnosis groups: 50 to 59 years, 60 to 69 years, and 70 years and older. Main Outcomes and Measures/UNASSIGNED:For each diabetes age-at-diagnosis group, a propensity score-matched control group of respondents who never developed diabetes was constructed. The association of diabetes with the incidence of key outcomes-including heart disease, stroke, disability, cognitive impairment, and all-cause mortality-was estimated and the association of diabetes vs no diabetes among the age-at-diagnosis case and matched control groups was compared. Results/UNASSIGNED:A total of 7739 HRS respondents developed diabetes and were included in the analysis (4267 women [55.1%]; mean [SD] age at diagnosis, 67.4 [9.9] years). The age-at-diagnosis groups included 1866 respondents at 50 to 59 years, 2834 at 60 to 69 years, and 3039 at 70 years or older; 28 321 HRS respondents never developed diabetes. Age at diagnosis of 50 to 59 years was significantly associated with incident heart disease (hazard ratio [HR], 1.66 [95% CI, 1.40-1.96]), stroke (HR, 1.64 [95% CI, 1.30-2.07]), disability (HR, 2.08 [95% CI, 1.59-2.72]), cognitive impairment (HR, 1.30 [95% CI, 1.05-1.61]), and mortality (HR, 1.49 [95% CI, 1.29-1.71]) compared with matched controls, even when accounting for diabetes duration. These associations significantly decreased with advancing age at diagnosis. Respondents with diabetes diagnosed at 70 years or older only showed a significant association with the outcome of elevated mortality (HR, 1.08 [95% CI, 1.01-1.17]). Conclusions and Relevance/UNASSIGNED:The findings of this cohort study suggest that age at diabetes diagnosis was differentially associated with outcomes and that younger age groups were at elevated risk of heart disease, stroke, disability, cognitive impairment, and all-cause mortality. These findings reinforce the clinical heterogeneity of diabetes and highlight the importance of improving diabetes management in adults with earlier diagnosis.

Factors associated with hospital admission and severe outcomes for older patients with COVID-19

Kim, Jiyu; Blaum, Caroline; Ferris, Rosie; Arcila-Mesa, Mauricio; Do, Hyungrok; Pulgarin, Claudia; Dolle, Johanna; Scherer, Jennifer; Kalyanaraman Marcello, Roopa; Zhong, Judy
BACKGROUND:Morbidity and death due to coronavirus disease 2019 (COVID-19) experienced by older adults in nursing homes have been well described, but COVID-19's impact on community-living older adults is less studied. Similarly, the previous ambulatory care experience of such patients has rarely been considered in studies of COVID-19 risks and outcomes. METHODS:To investigate the relationship of advanced age (65+), on risk factors associated with COVID-19 outcomes in community-living elders, we identified an electronic health records cohort of older patients aged 65+ with laboratory-confirmed COVID-19 with and without an ambulatory care visit in the past 24 months (n = 47,219) in the New York City (NYC) academic medical institutions and the NYC public hospital system from January 2020 to February 2021. The main outcomes are COVID-19 hospitalization; severe outcomes/Intensive care unit (ICU), intubation, dialysis, stroke, in-hospital death), and in-hospital death. The exposures include demographic characteristics, and those with ambulatory records, comorbidities, frailty, and laboratory results. RESULTS:The 31,770 patients with an ambulatory history had a median age of 74 years; were 47.4% male, 24.3% non-Hispanic white, 23.3% non-Hispanic black, and 18.4% Hispanic. With increasing age, the odds ratios and attributable fractions of sex, race-ethnicity, comorbidities, and biomarkers decreased except for dementia and frailty (Hospital Frailty Risk Score). Patients without ambulatory care histories, compared to those with, had significantly higher adjusted rates of COVID-19 hospitalization and severe outcomes, with strongest effect in the oldest group. CONCLUSIONS:In this cohort of community-dwelling older adults, we provided evidence of age-specific risk factors for COVID-19 hospitalization and severe outcomes. Future research should explore the impact of frailty and dementia in severe COVID-19 outcomes in community-living older adults, and the role of engagement in ambulatory care in mitigating severe disease.

Perceptions of Treatment Burden Among Caregivers of Elders With Diabetes and Co-morbid Alzheimer's Disease and Related Dementias: A Qualitative Study

Vaughan Dickson, Victoria; Melnyk, Halia; Ferris, Rosie; Leon, Alejandra; Arcila-Mesa, Mauricio; Rapozo, Crystalinda; Chodosh, Joshua; Blaum, Caroline S
Many older adults with diabetes (DM) have co-occurring Alzheimer's Disease (AD) and AD-Related Dementias (ADRD). Complex treatment plans may impose treatment burden for caregivers responsible for day-to-day self-management. The purpose of this qualitative study was to describe caregiver perceptions of treatment burden for people with DM-AD/ADRD. Caregivers (n = 33) of patients with DM-AD/ADRD participated in semi-structured interviews about their caregiver role and perceptions of treatment burden of DM-AD/ADRD management. Qualitative data were analyzed using content analysis (ATLAS.ti). Caregivers reported high levels of burden related to complex treatment/self-management for patients with DM-AD/ADRD that varied day-to-day with the patient's cognitive status. Four themes were: (1) trajectory of treatment burden; (2) navigating multiple healthcare providers/systems of care; (3) caregiver role conflict; and (4) emotional burden. Interventions to reduce caregiver treatment burden should include activating supportive services, education, and care coordination especially, if patient treatment increases in complexity over time.

Cardiovascular disease and cumulative incidence of cognitive impairment in the Health and Retirement Study

Covello, Allyson L; Horwitz, Leora I; Singhal, Shreya; Blaum, Caroline S; Li, Yi; Dodson, John A
BACKGROUND:We sought to examine whether people with a diagnosis of cardiovascular disease (CVD) experienced a greater incidence of subsequent cognitive impairment (CI) compared to people without CVD, as suggested by prior studies, using a large longitudinal cohort. METHODS:We employed Health and Retirement Study (HRS) data collected biennially from 1998 to 2014 in 1305 U.S. adults age ≥ 65 newly diagnosed with CVD vs. 2610 age- and gender-matched controls. Diagnosis of CVD was adjudicated with an established HRS methodology and included self-reported coronary heart disease, angina, heart failure, myocardial infarction, or other heart conditions. CI was defined as a score < 11 on the 27-point modified Telephone Interview for Cognitive Status. We examined incidence of CI over an 8-year period using a cumulative incidence function accounting for the competing risk of death. RESULTS:Mean age at study entry was 73 years, 55% were female, and 13% were non-white. Cognitive impairment developed in 1029 participants over 8 years. The probability of death over the study period was greater in the CVD group (19.8% vs. 13.8%, absolute difference 6.0, 95% confidence interval 2.2 to 9.7%). The cumulative incidence analysis, which adjusted for the competing risk of death, showed no significant difference in likelihood of cognitive impairment between the CVD and control groups (29.7% vs. 30.6%, absolute difference - 0.9, 95% confidence interval - 5.6 to 3.7%). This finding did not change after adjusting for relevant demographic and clinical characteristics using a proportional subdistribution hazard regression model. CONCLUSIONS:Overall, we found no increased risk of subsequent CI among participants with CVD (compared with no CVD), despite previous studies indicating that incident CVD accelerates cognitive decline.

Post-Discharge Health Status and Symptoms in Patients with Severe COVID-19

Weerahandi, Himali; Hochman, Katherine A; Simon, Emma; Blaum, Caroline; Chodosh, Joshua; Duan, Emily; Garry, Kira; Kahan, Tamara; Karmen-Tuohy, Savannah L; Karpel, Hannah C; Mendoza, Felicia; Prete, Alexander M; Quintana, Lindsey; Rutishauser, Jennifer; Santos Martinez, Leticia; Shah, Kanan; Sharma, Sneha; Simon, Elias; Stirniman, Ana Z; Horwitz, Leora I
BACKGROUND:Little is known about long-term recovery from severe COVID-19 disease. Here, we characterize overall health, physical health, and mental health of patients 1 month after discharge for severe COVID-19. METHODS:This was a prospective single health system observational cohort study of patients ≥ 18 years hospitalized with laboratory-confirmed COVID-19 disease who required at least 6 l of oxygen during admission, had intact baseline cognitive and functional status, and were discharged alive. Participants were enrolled between 30 and 40 days after discharge. Outcomes were elicited through validated survey instruments: the PROMIS® Dyspnea Characteristics and PROMIS® Global Health-10. RESULTS:A total of 161 patients (40.6% of eligible) were enrolled; 152 (38.3%) completed the survey. Median age was 62 years (interquartile range [IQR], 50-67); 57 (37%) were female. Overall, 113/152 (74%) participants reported shortness of breath within the prior week (median score 3 out of 10 [IQR 0-5]), vs 47/152 (31%) pre-COVID-19 infection (0, IQR 0-1), p < 0.001. Participants also rated their physical health and mental health as worse in their post-COVID state (43.8, standard deviation 9.3; mental health 47.3, SD 9.3) compared to their pre-COVID state, (54.3, SD 9.3; 54.3, SD 7.8, respectively), both p < 0.001. Physical and mental health means in the general US population are 50 (SD 10). A total of 52/148 (35.1%) patients without pre-COVID oxygen requirements needed home oxygen after hospital discharge; 20/148 (13.5%) reported still using oxygen at time of survey. CONCLUSIONS:Patients with severe COVID-19 disease typically experience sequelae affecting their respiratory status, physical health, and mental health for at least several weeks after hospital discharge.

Cardiovascular disease risk prediction for people with type 2 diabetes in a population-based cohort and in electronic health record data

Szymonifka, Jackie; Conderino, Sarah; Cigolle, Christine; Ha, Jinkyung; Kabeto, Mohammed; Yu, Jaehong; Dodson, John A; Thorpe, Lorna; Blaum, Caroline; Zhong, Judy
OBJECTIVE:Electronic health records (EHRs) have become a common data source for clinical risk prediction, offering large sample sizes and frequently sampled metrics. There may be notable differences between hospital-based EHR and traditional cohort samples: EHR data often are not population-representative random samples, even for particular diseases, as they tend to be sicker with higher healthcare utilization, while cohort studies often sample healthier subjects who typically are more likely to participate. We investigate heterogeneities between EHR- and cohort-based inferences including incidence rates, risk factor identifications/quantifications, and absolute risks. MATERIALS AND METHODS/METHODS:This is a retrospective cohort study of older patients with type 2 diabetes using EHR from New York University Langone Health ambulatory care (NYULH-EHR, years 2009-2017) and from the Health and Retirement Survey (HRS, 1995-2014) to study subsequent cardiovascular disease (CVD) risks. We used the same eligibility criteria, outcome definitions, and demographic covariates/biomarkers in both datasets. We compared subsequent CVD incidence rates, hazard ratios (HRs) of risk factors, and discrimination/calibration performances of CVD risk scores. RESULTS:The estimated subsequent total CVD incidence rate was 37.5 and 90.6 per 1000 person-years since T2DM onset in HRS and NYULH-EHR respectively. HR estimates were comparable between the datasets for most demographic covariates/biomarkers. Common CVD risk scores underestimated observed total CVD risks in NYULH-EHR. DISCUSSION AND CONCLUSION/CONCLUSIONS:EHR-estimated HRs of demographic and major clinical risk factors for CVD were mostly consistent with the estimates from a national cohort, despite high incidences and absolute risks of total CVD outcome in the EHR samples.

Diabetic management in older adults with dementia-are we overtreating? [Meeting Abstract]

Kennedy, H; Ferris, R; Arcila-Mesa, M; Rapozo, C; Chodosh, J; Blaum, C S
Background: Up to one third of older adults with diabetes (DM) have co-occurring cognitive impairment and/or Alzheimer's disease and Related Dementias (ADRD). These patients are more likely to experience episodes of hypo and hyperglycemia. The American Geriatric Society (AGS) and American Diabetic Association (ADA) recommend liberalizing hemoglobin (Hb) A1c targets for patients with multiple comorbidities, but the impact of ADRD on glycemic management of patients with DM-ADRD is unknown.
Method(s): Within the primary care and endocrine clinics in the NYU Langone Health System, we collected characteristics of DM-ADRD patients participating in a DM-ADRD clinical quality improvement program. We administratively collected patients' most recent (within18 months) HbA1c from the Electronic Medical Record. We also surveyed the English and Spanish-speaking caregivers (CG) of these DM-ADRD patients. The CG survey included a measure of CG-reported patient dementia severity using the Dementia Severity Rating Scale (DSRS). We examined the relationship between the DSRS score and HbA1c.
Result(s): Patients (n=173) had a mean age of 79.7 (+/-7.18) and a mean HbA1c of 7.08%. 63% (n=106) were female, 63% (n=106) white; 37% (n=64) identified as being Latino/Hispanic. The mean DSRS score was 25 (+/-12.7) (range: 0-54), within the range of moderate cognitive impairment (18-36). Those older than 75 and those who were Spanish speaking had higher DSRS scores (26.1, p=.02; and 26.7, p=.04, respectively). Mean HbA1c of patients in the severe DSRS range (scores 37-54) was 6.81 (N=35) and was lower than in patients with moderate and mild dementia severity (mean 7.15 and 7.24, respectively); however, this difference was not statistically significant.
Conclusion(s): While the data does not confirm a statistically significant relationship between dementia severity and lower A1c, this finding is worrisome for DM-ADRD patients. Our data suggests possible overtreatment and if confirmed, there is a clear need for increased family and provider education and quality improvement programs for this vulnerable population

Factors associated with burden for caregivers of patients with diabetes and dementia [Meeting Abstract]

Battista, C; Chodosh, J; Ferris, R; Arcila-Mesa, M; Rapozo, C; Blaum, C S
Background: Caregivers (CGs) of older-adults with Alzheimer's disease and related dementias (ADRD) and CGs of older-adults with diabetes (DM) report substantial CG burden. CG burden is known to be linked to patients' behavioral problems, poor cognition, and increased dependency. There is no literature addressing CG burden in CGs of individuals with co-occurring diabetes and dementia (DM-ADRD). The aim of this study was to identify CG and care-recipient (CR) factors associated with high levels of CG burden in CGs of DM-ADRD patients.
Method(s): This study used bivariate and descriptive statistics to analyze surveys collected as part of a quality improvement intervention being conducted at NYU Langone Health primary care and endocrine Faculty Group Practices and Family Health Centers. Inclusion criteria for patients were age >= 65, cognitive impairment, and DM with recent HbA1c > 6.4 or ever prescribed hyperglyemic medication. Telephonic surveys were conducted with CGs of eligible patients. The Treatment Burden Questionnaire (TBQ) was used to measure CG burden. TBQ results were analyzed for association with CG factors including age, sex, race, relationship to patient, education level, residence status, and level of social support, as well as CR factors including age, sex, race, dementia severity, Charlson comorbidity score, and recent HbA1c values.
Result(s): CGs that completed surveys (n=58) had a mean age of 54.3 years, 74% (n=43) female, 46% (n=27) white, 84% (n=49) were children of CRs, 70% (n=41) had education beyond 12th grade, and 55% (n=32) lived separately from CR. CRs of CGs that completed surveys (n=58) had a mean age of 80.5 years, 67% (n=39) female, 67% (n=37) white. We found CGs who were male, Asian, co-resident, with low level of social support, of CRs with more-advanced dementia, and of CRs with recent out-of-range HbA1c had significantly higher levels of CG burden (p<0.1).
Conclusion(s): Our study demonstrates there are several CG and CR factors that are associated with increased levels of CG burden in this population. Findings may assist in identification of CGs at risk for increased burden. If these results are found to be replicable, future studies should focus on the development of prevention and treatment plans consistent with these findings
