ABSTRACT
BACKGROUND: The Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) is a tool that systematically guides decision-making and reporting of adaptations made to evidence-based interventions. Using FRAME, we documented the process and outcomes of adapting the Savvy Caregiver Program (SCP) for Korean American dementia caregivers. METHODS: Sequential adaptation was initiated with linguistic attunement, followed by pilot implementation and full adaptation. Our data-driven adaptation with multiple data sources and a feedback loop among multiple stakeholders yielded a total of 32 modifications, and each was coded according to the eight domains of FRAME: (1) what was modified, (2) who participated in recommending and deciding the modification to be made, (3) when the modification occurred, (4) whether the modification was planned, (5) whether the modification was fidelity-consistent, (6) whether the modification was temporary, (7) at what level of delivery, the modification was made, and (8) why the modification was made. RESULTS: The areas of adaptation were evenly distributed across context (37.5%), content (31.2%), and training (31.2%). The primary reasons for modification were for engagement (62.5%), followed by fit with recipients (43.8%) and outcome improvement (31.1%). About 66% of the modifications were applied to the entire target group, and all modifications were fidelity-consistent. CONCLUSIONS: The FRAME categorization provided a detailed understanding of the process and nature of adapting the SCP and served as a foundation for further implementation and scale-up. FRAME not only serves as a guide for adapting evidence-based interventions but also promotes their replicability and scalability.

OBJECTIVES: Project VITAL At Home aimed to combat social isolation and loneliness in family caregivers of people with dementia through purposeful engagement and connection. This project examined the effects of technology on caregiver loneliness and well-being, as well as their technology experiences, during the COVID-19 pandemic. METHODS: Family caregivers were provided iN2L tablets and access to Alzheimer's Association supportive programs. Caregivers (n = 124) completed online surveys at pre and post evaluation points (average 7 months apart) to assess loneliness, subjective well-being (affect), supportive program usage, and tablet experiences. RESULTS: Family caregivers had positive perceptions of the tablets for both themselves and their family members. Tablets had positive effects on caregiver well-being, including giving them an additional caregiver tool, alleviating stress, increasing satisfaction with quiet time, and improving access to supportive programs. Caregiver positive affect decreased, but no changes were observed for negative affect or loneliness. CONCLUSIONS: Family caregivers found value in the tablets and showed improvements in some aspects of well-being. Randomized trials are needed to more fully assess the benefits of the intervention. CLINICAL IMPLICATIONS: Pairing tablets with caregiving supports is a promising intervention to improve caregivers' access to vital resources and services and to improve their well-being.

BACKGROUND: Stroke commonly leads to disability and depression. Social connection and engagement can be protective against functional decline and depression in the general population. We investigated the effects of social connection and engagement on trajectories of function and depressive symptoms in stroke. METHODS: This is a longitudinal study, which included 898 participants with incident stroke from the HRS study (Health and Retirement Study) between 1998 and 2012. Multilevel modeling was used to examine associations of social connection and engagement with changes in functional limitations in instrumental activities of daily living (IADLs) and depressive symptoms over time. Models controlled for age, gender, education, and race/ethnicity. Moderation analyses examined whether high social connection and engagement reduced depressive symptoms for survivors with high IADL impairment. RESULTS: Social connection and engagement were generally associated with fewer IADL limitations and depressive symptoms at the time of stroke and after stroke. For example, participants who felt lonely and did not provide help to others before stroke had more IADL limitations. Prestroke volunteering was associated with less increase in IADL limitations with stroke and increase in having friends and providing help to others compared with one's prestroke status were associated with fewer IADL limitations after stroke. For depressive symptoms, participants who felt lonely and did not have a friend or partner before stroke had more depressive symptoms, and participants who had children residing nearby before stroke showed less increase in depressive symptoms. Moderation effects were not found for social connection and engagement on high IADL impairment and depressive symptoms. CONCLUSIONS: Findings suggest that social connection and engagement may reduce the negative physical and psychological outcomes of stroke, both at baseline and after stroke. Efforts to enhance social engagement and diminish loneliness may both enhance population well-being and enhance resilience and recovery from stroke and other illnesses.

OBJECTIVES: Higher inflammation has been linked to poor physical and mental health outcomes, and mortality, but few studies have rigorously examined whether changes in perceived stress and depressive symptoms are associated with increased inflammation within family caregivers and non-caregivers in a longitudinal design. DESIGN: Longitudinal Study. SETTING: REasons for Geographic And Racial Differences in Stroke cohort study. PARTICIPANTS: Participants included 239 individuals who were not caregivers at baseline but transitioned to providing substantial and sustained caregiving over time. They were initially matched to 241 non-caregiver comparisons on age, sex, race, education, marital status, self-rated health, and history of cardiovascular disease. Blood was drawn at baseline and approximately 9.3 years at follow-up for both groups. MEASUREMENTS: Perceived Stress Scale, Center for Epidemiological Studies-Depression, inflammatory biomarkers, including high-sensitivity C-reactive protein, D dimer, tumor necrosis factor alpha receptor 1, interleukin (IL)-2, IL-6, and IL-10 taken at baseline and follow-up. RESULTS: Although at follow-up, caregivers showed significantly greater worsening in perceived stress and depressive symptoms compared to non-caregivers, there were few significant associations between depressive symptoms or perceived stress on inflammation for either group. Inflammation, however, was associated with multiple demographic and health variables, including age, race, obesity, and use of medications for hypertension and diabetes for caregivers and non-caregivers. CONCLUSIONS: These findings illustrate the complexity of studying the associations between stress, depressive symptoms, and inflammation in older adults, where these associations may depend on demographic, disease, and medication effects. Future studies should examine whether resilience factors may prevent increased inflammation in older caregivers.

Chronic stress has been widely proposed to increase systemic inflammation, a pathway that may link stress with a heightened risk for many diseases. The chronic stress-inflammation relationship has been challenging to study in humans, however, and family caregiving has been identified as one type of stressful situation that might lead to increased inflammation. Previous studies of caregiving and inflammation have generally used small convenience samples, compared caregivers with poorly characterized control participants, and assessed inflammation only after caregivers provided care for extended periods of time. In the current project, changes over a 9-y period were examined on six circulating biomarkers of inflammation for 480 participants from a large population-based study. All participants reported no involvement in caregiving prior to the first biomarker assessment, and 239 participants then took on extensive and prolonged family caregiving responsibilities at some point prior to the second biomarker assessment. Incident caregivers were individually matched on multiple demographic and health history variables with participants who reported no caregiving responsibilities. Of the six biomarkers examined, only tumor necrosis factor alpha receptor 1 showed a significantly greater increase in caregivers compared with controls. This effect was small (d = 0.14), and no effects were found for a subset of 45 caregivers who were living with a spouse with dementia. These results are consistent with recent meta-analytic findings and challenge the widespread belief that caregiving is a substantial risk factor for increased inflammation. Future research is warranted on factors that may account for stress resilience in family caregivers.

OBJECTIVES: Positive caregiver adaptation over time may be associated with reports of positive aspects of caregiving (PAC). We examined differences in PAC by caregiving duration and social engagement, controlling for measures of distress. METHODS: Participants included 283 African American or White caregivers from the Caregiving Transitions Study with a wide range of caregiving durations. PAC are defined as positive appraisals that caregivers report about their role, such as feeling appreciated or confident. We fit multivariable linear models with the total PAC score as the outcome to assess its association with years of caregiving and social engagement (social network, monthly social contact). Models were adjusted for age, sex, race, marital status, relationship to care recipient, care recipient's dementia status, perceived stress and caregiving strain. RESULTS: Caregivers with higher social engagement reported significantly higher PAC. A non-significant trend was found in most analytic models for caregivers with longer duration of care to report higher PAC. African American caregivers reported higher PAC compared to White caregivers. Dementia caregivers reported lower PAC than non-dementia caregivers in models adjusting for demographics and social network size, but the association was attenuated with the addition of caregiving strain. DISCUSSION: Higher social engagement and longer duration of care tend to be associated with higher PAC after adjusting for demographics and measures of distress. Future studies should aim to leverage longitudinal data to understand whether caregivers shift appraisal to positive aspects of their role and explore implementation of caregiving interventions targeting PAC in order to improve the caregiving experience.

This study investigated stressors and strains, resources, and well-being among Black working caregivers (BWC) and White working caregivers (WWC) who participated in the Midlife in the United States study (Black: n = 49, White: n = 250). Comparisons were made between BWC and WWC for primary caregiving stressors, secondary strains, resources, and well-being, and hierarchical regression models tested associations among these factors. BWC reported less negative work-to-family spillover, more perceived control and religious/spiritual coping, and higher positive affect than WWC, complementing existing evidence of greater resilience among BWC. Secondary strains stemming from the workplace had stronger associations with well-being than primary caregiving stressors, confirming that the workplace deserves greater attention in stress research and interventions for working caregivers. Finally, perceived control, optimism, and family support were important resources for well-being for both BWC and WWC, substantiating their valuable role in interventions for working caregivers.
ABSTRACT
OBJECTIVES: Language accommodation is indispensable in making evidence-based interventions available and accessible to ethnic minorities with limited English proficiency. As part of the larger effort to culturally adapt the Savvy Caregiver Program for Korean American dementia caregivers, we first conducted linguistic adaptation, and the present study reports the preliminary findings on participants' changes in depressive Symptoms. METHODS: The linguistically adapted program was delivered to two small groups of Korean American dementia caregivers (total n = 13) by two Savvy-certified Korean-speaking trainers. Participants' depressive symptoms were assessed at three time points (pre-intervention, immediate post-intervention, and 6-month follow-up). RESULTS: Following the intervention, participants exhibited lowered depressive symptoms (t = 8.64, p < .001, Cohen's d = .89). This benefit was sustained at 6-month follow-up. CONCLUSIONS: Findings suggest that the therapeutic benefit of the Savvy Caregiver Program could potentially be shared with linguistic minorities when delivered in their native language. CLINICAL IMPLICATIONS: Although limited in its scope and nature, the pilot study with linguistic adaptation sheds light on efforts to close the gap in the evidence-based intervention delivery.
ABSTRACT
RATIONALE & OBJECTIVE: The safety of intensive blood pressure (BP) targets is controversial for persons with chronic kidney disease (CKD). We studied the effects of hypertension treatment on cerebral perfusion and structure in individuals with and without CKD. STUDY DESIGN: Neuroimaging substudy of a randomized trial. SETTING & PARTICIPANTS: A subset of participants in the Systolic Blood Pressure Intervention Trial (SPRINT) who underwent brain magnetic resonance imaging studies. Presence of baseline CKD was assessed by estimated glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio (UACR). INTERVENTION: Participants were randomly assigned to intensive (systolic BP <120 mm Hg) versus standard (systolic BP <140 mm Hg) BP lowering. OUTCOMES: The magnetic resonance imaging outcome measures were the 4-year change in global cerebral blood flow (CBF), white matter lesion (WML) volume, and total brain volume (TBV). RESULTS: A total of 716 randomized participants with a mean age of 68 years were enrolled; follow-up imaging occurred after a median 3.9 years. Among participants with eGFR <60 mL/min/1.73 m2 (n = 234), the effects of intensive versus standard BP treatment on change in global CBF, WMLs, and TBV were 3.38 (95% CI, 0.32 to 6.44) mL/100 g/min, -0.06 (95% CI, -0.16 to 0.04) cm3 (inverse hyperbolic sine-transformed), and -3.8 (95% CI, -8.3 to 0.7) cm3, respectively. Among participants with UACR >30 mg/g (n = 151), the effects of intensive versus standard BP treatment on change in global CBF, WMLs, and TBV were 1.91 (95% CI, -3.01 to 6.82) mL/100 g/min, 0.003 (95% CI, -0.13 to 0.13) cm3 (inverse hyperbolic sine-transformed), and -7.0 (95% CI, -13.3 to -0.3) cm3, respectively. The overall treatment effects on CBF and TBV were not modified by baseline eGFR or UACR; however, the effect on WMLs was attenuated in participants with albuminuria (P = 0.04 for interaction). LIMITATIONS: Measurement variability due to multisite design. CONCLUSIONS: Among adults with hypertension who have primarily early kidney disease, intensive versus standard BP treatment did not appear to have a detrimental effect on brain perfusion or structure. The findings support the safety of intensive BP treatment targets on brain health in persons with early kidney disease. FUNDING: SPRINT was funded by the National Institutes of Health (including the National Heart, Lung, and Blood Institute; the National Institute of Diabetes and Digestive and Kidney Diseases; the National Institute on Aging; and the National Institute of Neurological Disorders and Stroke), and this substudy was funded by the National Institutes of Diabetes and Digestive and Kidney Diseases. TRIAL REGISTRATION: SPRINT was registered at ClinicalTrials.gov with study number NCT01206062.

OBJECTIVES: Responding to racial/ethnic disparities in dementia diagnosis and care, we examined the role of race/ethnicity in the correspondence between subjective and objective ratings of cognitive impairment. Our examination focused on the two types of discordance: (1) positive ratings in the presence of cognitive impairment and (2) negative ratings in the absence of cognitive impairment. DESIGN AND PARTICIPANTS: A cross-sectional assessment was conducted using the data from the Harmonized Cognitive Assessment Protocol project, a sub-study of the Health and Retirement Study. Our analytic sample included 3,096 participants: 2,257 non-Hispanic Whites, 498 Blacks, and 341 Hispanics. MEASUREMENTS: Discordant groups were identified based on self-ratings of cognition (positive versus negative) and the Langa-Weir classification of cognitive impairment (normal versus impaired). RESULTS: Blacks and Hispanics were more prone to falsely positive perceptions of their cognitive function in the presence of cognitive impairment than non-Hispanic Whites. On the other hand, non-Hispanic Whites were more likely to manifest negative ratings even in the absence of cognitive impairment. CONCLUSION: Our findings demonstrate the critical role of race/ethnicity in determining discordance between subjective and objective measures of cognition and highlight the importance of a tailored effort to promote dementia diagnosis and care.

BACKGROUND: Limited English proficiency (LEP) of dementia caregivers poses a critical barrier to these caregivers' access to evidence-based interventions. In an effort to make such interventions available and accessible to dementia caregivers with LEP, in the present study we use Barrera and colleagues' (2011) three-step model of cultural adaptation: (1) information gathering, (2) preliminary adaptation, and (3) full adaptation. Selecting Korean Americans as a target group and the Savvy Caregiver Program (SCP) as a target intervention, we demonstrate the sequential process of cultural adaption and report the outcomes on feasibility and acceptability. METHODS: Preliminary adaptation with linguistic attunement was conducted by translating the SCP manual into Korean and certifying two lay individuals who were bilingual in English and Korean as Savvy trainers. The 6-week online SCP program was delivered by the two trainers in Korean with six to seven caregiver participants per trainer (N = 13). Feasibility and acceptability of the SCP for both caregiver participants and trainers were assessed using mixed methods, and their data then informed full adaptation. RESULTS: Findings not only showed the initial efficacy of the linguistically attuned SCP but also suggested areas for further modification. Data-driven assessment yielded a list of recommended changes for full adaptation, which was reviewed by the SCP developer to ensure fidelity and by community and research partners to confirm contextual and cultural relevance. CONCLUSIONS: The adopted changes are broadly summarized as representing logistical, technical, and cultural issues. Given our refined set of educational materials and implementation guidelines, we discuss future directions for research and development.

OBJECTIVES: The influence of childhood sexual abuse (CSA) may be seen immediately or across the life course. CSA is also associated with increased HIV-risk behavior, and greater likelihood of an HIV/STI diagnosis. The aim of this study was to explore the perspectives of CSA among older adults living with HIV. METHODS: Twenty-four adults living with HIV aged 50 to 67 years (mean age = 58.5 years), with a history of CSA, receiving care from an HIV clinic in South Carolina, participated in the study. In-depth semi-structured interviews were conducted, audio recorded and analyzed using a thematic analytic approach. The iterative analytic process included a three-step approach: discussion of initial thoughts and key concepts, identification and reconciliation of codes, and naming of emergent themes. RESULTS: Four themes emerged: Psychological issues due to CSA, relationship challenges due to CSA, self-blame, and reliving childhood trauma (subtheme: lack of influence of CSA today). Some participants reported feeling the influence of CSA several years after the event while others noted that that there was a lack of influence of CSA at present. CONCLUSIONS: Trauma-informed intervention programs are needed for older adults living with HIV who still experience the influence of their CSA experience. Future research should delve into the design and feasibility of implementing these programs.

OBJECTIVE: Studies investigating hearing interventions under-utilise and under-report treatment fidelity planning, implementation, and assessment. This represents a critical gap in the field that has the potential to impede advancements in the successful dissemination and implementation of interventions. Thus, our objective was to describe treatment fidelity planning and implementation for hearing intervention in the multi-site Ageing and Cognitive Health Evaluation in Elders (ACHIEVE) randomised controlled trial. DESIGN: Our treatment fidelity plan was based on a framework defined by the National Institutes of Health Behaviour Change Consortium (NIH BCC), and included strategies to enhance study design, provider training, and treatment delivery, receipt, and enactment. STUDY SAMPLE: To assess the fidelity of the ACHIEVE hearing intervention, we distributed a checklist containing criteria from each NIH BCC core treatment fidelity category to nine raters. RESULTS: The ACHIEVE hearing intervention fidelity plan satisfied 96% of NIH BCC criteria. Our assessment suggested a need for including clear, objective definitions of provider characteristics and non-treatment aspects of intervention delivery in future fidelity plans. CONCLUSIONS: The ACHIEVE hearing intervention fidelity plan can serve as a framework for the application of NIH BCC fidelity strategies for future studies and enhance the ability of researchers to reliably implement evidence-based interventions.

Guided by stress and coping theory, qualitative content analysis was used to examine student written assignment responses (N = 100) about the importance of and student preparedness for completing their own advance directive (AD). Codes represented primary and secondary appraisals, coping, and outcomes. Primary appraisals were 47% benign, 47% stressful, and 6% irrelevant. Benign primary appraisals were associated with reporting greater internal and external resources and intent to complete an AD. Exposing students to information about AD can be useful, but student completion of an AD should be reserved for classes that help students process emotions and information about their preferences for end-of-life care.

PURPOSE: Hypertension is a risk factor for cognitive impairment; however, the mechanisms leading to cognitive changes remain unclear. In this cross-sectional study, we evaluate the impact of white matter lesion (WML) burden on brain functional connectivity (FC) and cognition in a large cohort of hypertensive patients from the Systolic Blood Pressure Intervention Trial (SPRINT) at baseline. METHODS: Functional networks were identified from baseline resting state functional MRI scans of 660 SPRINT participants using independent component analysis. WML volumes were calculated from structural MRI. Correlation analyses were carried out between mean FC of each functional network and global WML as well as WML within atlas-defined white matter regions. For networks of interest, voxel-wise-adjusted correlation analyses between FC and regional WML volume were performed. Multiple variable linear regression models were built for cognitive test performance as a function of network FC, followed by mediation analysis. RESULTS: Mean FC of the default mode network (DMN) was negatively correlated with global WML volume, and regional WML volume within the precuneus. Voxel-wise correlation analyses revealed that regional WML was negatively correlated with FC of the DMN's left lateral temporal region. FC in this region of the DMN was positively correlated to performance on the Montreal Cognitive Assessment and demonstrated significant mediation effects. Additional networks also demonstrated global and regional WML correlations; however, they did not demonstrate an association with cognition. CONCLUSION: In hypertensive patients, greater WML volume is associated with lower FC of the DMN, which in turn is related to poorer cognitive test performance. TRIAL REGISTRATION: NCT01206062.

BACKGROUND: It is unclear whether faster progression of atherosclerosis explains the higher risk of cardiovascular events in CKD. The objectives of this study were to 1. Characterize the associations of CKD with presence and morphology of atherosclerotic plaques on carotid magnetic resonance imaging (MRI) and 2. Examine the associations of baseline CKD and carotid atherosclerotic plaques with subsequent cardiovascular events. METHODS: In a subgroup (N = 465) of Systolic Blood Pressure Intervention Trial. (SPRINT) participants, we measured carotid plaque presence and morphology at baseline and after 30-months with MRI. We examined the associations of CKD (baseline eGFR < 60 ml/min/1.73m2) with progression of carotid plaques and the SPRINT cardiovascular endpoint. RESULTS: One hundred and ninety six (42%) participants had CKD. Baseline eGFR in the non-CKD and CKD subgroups were 77 ± 14 and 49 ± 8 ml/min/1.73 m2, respectively. Lipid rich necrotic-core plaque was present in 137 (29.5%) participants. In 323 participants with both baseline and follow-up MRI measurements of maximum wall thickness, CKD was not associated with progression of maximum wall thickness (OR 0.62, 95% CI 0.36 to 1.07, p = 0.082). In 96 participants with necrotic core plaque at baseline and with a valid follow-up MRI, CKD was associated with lower odds of progression of necrotic core plaque (OR 0.41, 95% CI 0.17 to 0.95, p = 0.039). There were 28 cardiovascular events over 1764 person-years of follow-up. In separate Cox models, necrotic core plaque (HR 2.59, 95% CI 1.15 to 5.85) but not plaque defined by maximum wall thickness or presence of a plaque component (HR 1.79, 95% CI 0.73 to 4.43) was associated with cardiovascular events. Independent of necrotic core plaque, CKD (HR 3.35, 95% CI 1.40 to 7.99) was associated with cardiovascular events. CONCLUSIONS: Presence of necrotic core in carotid plaque rather than the presence of plaque per se was associated with increased risk of cardiovascular events. We did not find CKD to be associated with faster progression of necrotic core plaques, although both were independently associated with cardiovascular events. Thus, CKD may contribute to cardiovascular disease principally via mechanisms other than atherosclerosis such as arterial media calcification or stiffening.

BACKGROUND: Intensively treating hypertension may benefit cardiovascular disease and cognitive function, but at the short-term expense of reduced kidney function. METHODS: We investigated markers of kidney function and the effect of intensive hypertension treatment on incidence of dementia and mild cognitive impairment (MCI) in 9361 participants in the randomized Systolic Blood Pressure Intervention Trial, which compared intensive versus standard systolic BP lowering (targeting <120 mm Hg versus <140 mm Hg, respectively). We categorized participants according to baseline and longitudinal changes in eGFR and urinary albumin-to-creatinine ratio. Primary outcomes were occurrence of adjudicated probable dementia and MCI. RESULTS: Among 8563 participants who completed at least one cognitive assessment during follow-up (median 5.1 years), probable dementia occurred in 325 (3.8%) and MCI in 640 (7.6%) participants. In multivariable adjusted analyses, there was no significant association between baseline eGFR <60 ml/min per 1.73 m2 and risk for dementia or MCI. In time-varying analyses, eGFR decline ≥30% was associated with a higher risk for probable dementia. Incident eGFR <60 ml/min per 1.73 m2 was associated with a higher risk for MCI and a composite of dementia or MCI. Although these kidney events occurred more frequently in the intensive treatment group, there was no evidence that they modified or attenuated the effect of intensive treatment on dementia and MCI incidence. Baseline and incident urinary ACR ≥30 mg/g were not associated with probable dementia or MCI, nor did the urinary ACR modify the effect of intensive treatment on cognitive outcomes. CONCLUSIONS: Among hypertensive adults, declining kidney function measured by eGFR is associated with increased risk for probable dementia and MCI, independent of the intensity of hypertension treatment.

Witnessing end-of-life suffering of loved ones is an underappreciated stressor that may affect caregiver bereavement. We interviewed 61 spousal caregivers of hospice patients who died within the past 6-18 months. Higher rumination about suffering and lower feelings of relief was related to poorer well-being. Rumination by caregivers about end-of-life suffering was an important predictor of depression and complicated grief. Most caregivers viewed the death as at least in part a relief. One important focus of grief support may be to help caregivers find productive ways to avoid rumination and use other forms of coping and to acknowledge feelings of relief.

IMPORTANCE: Hypertension and carotid stenosis are both risk factors for stroke, but the presence of carotid stenosis might dampen enthusiasm for tight control of hypertension because of concerns for hypoperfusion. OBJECTIVE: To determine the extent to which there are opportunities to potentially improve pharmacotherapy for hypertension in patients known to have asymptomatic high-grade carotid stenosis. DESIGN: We examined anti-hypertensive medication prescription and adherence to evidence-based hypertension treatment guidelines in a cross-sectional analysis of baseline data of patients enrolled in a clinical trial. SETTING: The Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2) is a multicenter prospective randomized open blinded end-point clinical trial of intensive medical management with or without revascularization by endarterectomy or stenting for asymptomatic high-grade carotid stenosis. PARTICIPANTS: 1479 participants (38.6% female; mean age 69.8 years) from 132 clinical centers enrolled in the CREST-2 trial as of April 6, 2020 who were taking ≥1 antihypertensive drug at baseline. EXPOSURES: Pharmacotherapy for hypertension. MAIN OUTCOME: Adherence to evidence-based guidelines for treating hypertension. RESULTS: Of 1458 participants with complete data, 26% were on one, 31% on 2, and 43% on ≥3 antihypertensive medications at trial entry. Thirty-two percent of participants were prescribed thiazide; 74%, angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB); 38%, calcium channel blocker (CCB); 56%, a beta blocker; 11%, loop diuretic; and 27%, other. Of those prescribed a single antihypertensive medication, the proportion prescribed thiazide was 5%; ACEI or ARB, 55%, and CCB, 11%. The prevalence of guideline-adherent regimens was 34% (95% CI, 31-36%). CONCLUSIONS AND RELEVANCE: In a diverse cohort with severe carotid disease and hypertension, non-adherence to hypertension guidelines was common. All preferred classes of antihypertensive drug were under-prescribed. Using staged iterative guideline-based care for hypertension, CREST-2 will characterize drug tolerance and stroke rates under these conditions.

Background and Purpose- Persistent depression after ischemic stroke is common in stroke survivors and may be even higher in family caregivers, but few studies have examined depressive symptom levels and their predictors in patient and caregiver groups simultaneously. Methods- Stroke survivors and their family caregivers (205 dyads) were enrolled from the national REGARDS study (Reasons for Geographic and Racial Differences in Stroke) into the CARES study (Caring for Adults Recovering from the Effects of Stroke) ≈9 months after a first-time ischemic stroke. Demographically matched stroke-free dyads (N=205) were also enrolled. Participants were interviewed by telephone, and depressive symptoms were assessed with the 20-item Center for Epidemiological Studies-Depression scale. Results- Significant elevations in depressive symptoms (Ps<0.03) were observed for stroke survivors (M=8.38) and for their family caregivers (M=6.42) relative to their matched controls (Ms=5.18 and 4.62, respectively). Stroke survivors reported more symptoms of depression than their caregivers (P=0.008). No race or sex differences were found, but differential prediction of depressive symptom levels was found across patients and caregivers. Younger age and having an older caregiver were associated with more depressive symptoms in stroke survivors while being a spouse caregiver and reporting fewer positive aspects of caregiving were associated with more depressive symptoms in caregivers. The percentage of caregivers at risk for clinically significant depression was lower in this population-based sample (12%) than in previous studies of caregivers from convenience or clinical samples. Conclusions- High depressive symptom levels are common 9 months after first-time ischemic strokes for stroke survivors and family caregivers, but rates of depressive symptoms at risk for clinical depression were lower for caregivers than previously reported. Predictors of depression differ for patients and caregivers, and standards of care should incorporate family caregiving factors.
