BACKGROUND/UNASSIGNED:The impact of preventing hypertension and maintaining normal blood pressure (BP) on life expectancy and healthy life expectancy (HLE) among Black adults, who are disproportionately affected by hypertension, has not been quantified. METHODS/UNASSIGNED:We used a discrete event simulation to estimate life expectancy and HLE among a cohort of Black adults from the Jackson Heart Study (n=4933) from age 20 to 100 years or until death. We modeled preventing hypertension as having BP <130/80 mm Hg and maintaining normal BP as having BP <120/80 mm Hg across the lifespan. In the primary analysis, we assumed that lowering BP decreased the risk of cardiovascular disease events, resulting in life expectancy and HLE gains. In a secondary analysis, we assumed that preventing hypertension and maintaining normal BP directly reduced both cardiovascular disease and mortality risk. RESULTS/UNASSIGNED:At age 20 years, the projected average life expectancy was age 80.8 (95% uncertainty interval [UI], 80.6-81.1) years, and HLE was 70.5 (95% UI, 70.3-70.7) healthy life years. In the primary analysis, preventing hypertension and maintaining normal BP added 0.9 (95% UI, 0.8-1.1) and 1.1 (95% UI, 0.9-1.3) years to life expectancy, respectively, and 2.7 (95% UI, 2.6-2.9) and 2.9 (95% UI, 2.7-3.1) healthy life years to HLE, respectively. In the secondary analysis, preventing hypertension and maintaining normal BP added 4.5 (95% UI, 4.3-4.6) and 4.6 (95% UI, 4.4-4.8) years to life expectancy, respectively, and 5.7 (95% UI, 5.6-5.8) and 5.9 (95% UI, 5.7-6.0) healthy life years to HLE, respectively. CONCLUSIONS/UNASSIGNED:Preventing hypertension and maintaining normal BP were projected to increase life expectancy and HLE among Black adults.

BACKGROUND:Hearing loss is highly prevalent among older adults and has been associated with an increased likelihood of falling. We aimed to examine the effect of a hearing intervention on falls over 3 years among older adults in a secondary analysis of the ACHIEVE study. METHODS:The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study was a 3-year, unmasked, randomised controlled trial of adults aged 70-84 years at enrolment with untreated hearing loss and without substantial cognitive impairment. Participants were recruited at four US community-based field sites from two study populations: (1) an ongoing observational study of cardiovascular health (Atherosclerosis Risk in Communities [ARIC] study), and (2) de novo from the community. Participants were randomly assigned (1:1) to a hearing intervention (audiological counselling and provision of hearing aids) or a health education control (didactic education and enrichment activities covering chronic disease prevention topics). A prespecified exploratory outcome was falls. Self-reported falls in the past 12 months were assessed at baseline and annually for 3 years, and analysed by intention to treat with covariate adjustment. The study was registered with ClinicalTrials.gov, NCT03243422, and is completed. FINDINGS/RESULTS:Between Nov 9, 2017, and Oct 25, 2019, 3004 individuals were screened for eligibility and 977 (238 [24%] from the ARIC study and 739 [76%] de novo) were randomly assigned, with 490 (50%) in the hearing intervention group and 487 (50%) in the health education control group. Overall mean age was 76·8 years (SD 4·0), 523 (54%) participants were female and 454 (46%) were male, and 112 (11%) were Black, 858 (88%) were White, and seven (1%) were other race. In adjusted analyses, the intervention group had a 27% reduction in the mean number of falls over 3 years compared with the control group (intervention group: 1·45 [95% CI 1·28 to 1·61]; control group: 1·98 [1·82 to 2·15]; mean difference: -0·54 [95% CI -0·77 to -0·31]). This 3-year effect of hearing intervention was consistent across both the ARIC and de novo study populations. INTERPRETATION/CONCLUSIONS:Hearing intervention versus a health education control was associated with a reduction in the mean number of falls over 3 years in older adults. Ongoing follow-up of ACHIEVE participants in a separate follow-up study (NCT05532657) will enable examination of the longer term effects of hearing intervention on falls.

RATIONALE & OBJECTIVE/OBJECTIVE:Despite national efforts, the uptake of home dialysis (peritoneal dialysis or home hemodialysis) remains low. Characteristics of the built environment may differentially impact home dialysis use. STUDY DESIGN/METHODS:Retrospective cohort study (2010-2019). SETTING & PARTICIPANTS/METHODS:1,103,695 adults (aged≥18 years) initiating dialysis in the US Renal Data System. EXPOSURE/METHODS:We examined 3 built environment domains based on residential ZIP code: (1) medically underserved areas (MUAs), defined as neighborhoods with limited primary care access; (2) distance to the nearest dialysis facility; and (3) distribution of housing characteristics (structure and overcrowding). OUTCOME/RESULTS:Uptake of home dialysis modalities at dialysis initiation. ANALYTICAL APPROACH/METHODS:We quantified associations between built environment characteristics and home dialysis initiation using multilevel logistic regression stratified by urbanicity type (urban, suburban, small-town, and rural). RESULTS:Among adults initiating dialysis, 40.8% lived in MUAs. Across ZIP codes, the mean percentage of overcrowded housing was 4.2% (SD, 4.7%), and the percentage of detached housing was 61.1% (SD, 21.1%); mean distance to the nearest dialysis facility was 5.5km (SD, 9.1km). Living in MUAs was associated with reduced home dialysis use only in urban (OR, 0.94; 95% CI, 0.91-0.96) and suburban (OR, 0.92; 95% CI, 0.89-0.94) areas. Similarly, housing overcrowding was associated with decreased home dialysis use only in urban (OR, 0.88; 95% CI, 0.86-0.89) and suburban (OR, 0.91; 95% CI, 0.90-0.93) areas. Longer distance to a dialysis facility was the most salient neighborhood factor associated with increased home dialysis use in small towns (OR, 1.14; 95% CI, 1.12-1.16) and rural areas (OR, 1.17; 95% CI, 1.15-1.19). LIMITATIONS/CONCLUSIONS:Housing characteristics were measured at the ZIP code level. CONCLUSIONS:Built environment characteristics associated with home dialysis uptake vary by urbanicity. Policies should address built environment barriers that are specific to urbanicity level. For example, increasing the frequency of dialysate delivery schedules could address housing space constraints in urban and suburban areas, and promoting home dialysis might be more effective for patients living far from dialysis centers in small-town and rural areas.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Healthcare is increasingly being delivered in the outpatient setting, but robust quality improvement programs and performance metrics are lacking in ambulatory care, particularly specialty-based ambulatory care. METHODS:To promote quality improvement in ambulatory care, we developed an infrastructure to create specialty-specific quality measures and dashboards that could be used to display providers' performance across relevant measures to individual providers and institutional leaders. RESULTS:The products of this program include a governance and infrastructure for specialty-specific ambulatory quality metrics as well as two distinct dashboards for data display. One dashboard is provider-facing, displaying provider's performance on specialty-specific measures as compared to institutional standards. The second dashboard is a leadership dashboard that provides overall and provider-level information on performance across measures. CONCLUSIONS:The Specialty-based Ambulatory Quality program reflects a systematic, institutionally-supported quality improvement framework that can be applied across diverse ambulatory specialties. As next steps, we plan to evaluate the program's impact on provider performance across measures and expand this program to other specialties practicing in the outpatient setting.

BACKGROUND/UNASSIGNED:Systematic screening individuals with non-invasive devices may improve diagnosis of atrial fibrillation (AF) and reduce adverse clinical events. We systematically reviewed the existing literature to determine the yield of new AF diagnosis associated with systematic AF screening, the relative increase in yield of new AF diagnosis with systematic screening compared to usual care, and the effect of systematic AF screening on clinical outcomes compared with usual care. METHODS/UNASSIGNED:The Medline, Embase, Web of Science and Cochrane Library databases were searched from inception through 1st February 2025 for prospective cohort studies or randomised clinical trials (RCTs) of systematic AF screening with the outcome of incidence of previously undiagnosed AF from screening. Incidence rates (IR) and relative risks were calculated and random effects meta-analysis performed to synthesise rates of AF in prospective cohort studies and RCTs, as well as outcomes in RCTs. FINDINGS/UNASSIGNED:From 3806 unique records we included 32 studies representing 735,542 participants from 8 RCTs and 24 prospective cohorts. The diagnosis rate for incident AF in prospective cohorts was 2.75% (95% CI 1.87-3.62), and the pooled relative risk in RCTs was 2.22 (95% CI 1.41-3.50). The use of age and NT-proBNP (IR 4.36%, 95% CI 3.77-5.08) or AF risk score classification (4.79%, 95% CI 3.62-6.29) led to higher new AF diagnosis yields than age alone (0.93%, 95% CI 0.28-2.99). Pooled data from RCTs did not demonstrate an effect of screening on death (RR 1.01, 95% CI 0.97-1.05), cardiovascular hospitalisation (1.00, 95% CI 0.97-1.03), stroke (0.95, 95% CI 0.87-1.04) or bleeding (1.08, 95% CI 0.91-1.29). INTERPRETATION/UNASSIGNED:Systematic screening for AF using non-invasive devices is associated with increased diagnosis of AF, but not reduced adverse clinical events. Screening studies of AF utilising alternative risk stratifications and outcome measures are required.

BACKGROUND:This study aimed to explore whether patients' perception of procedural fairness in physicians' communication was associated with willingness to follow doctor's recommendations, self-efficacy beliefs, dietary behaviors, and body mass index. METHODS:(43.6% Black, 40.7% Hispanic/Latino, 55.8% female, mean age = 50 years), who enrolled in a weight management study in two New York City healthcare institutions. We conducted ordinary least squares path analyses with bootstrapping to explore direct and indirect associations among procedural fairness, willingness to follow recommendations, self-efficacy, dietary behaviors, and body mass index, while controlling for age and gender. RESULTS:Serial, multiple mediator models indicated that higher procedural fairness was associated with an increased willingness to follow recommendations which, in turn, was associated with healthier dietary behaviors and a lower BMI (indirect effect =  - .02, SE = .01; 95% CI [- .04 to - .01]). Additionally, higher procedural fairness was associated with elevated dietary self-efficacy, which was, in turn, was associated with healthier dietary behaviors and lower BMI (indirect effect =  - .01, SE = .003; 95% CI [- .02 to - .002]). CONCLUSIONS:These findings highlight the importance of incorporating procedural fairness in physician-patient communication concerning weight management in diverse primary care patients.

Text communication between newborns' caregivers and healthcare workers allows for real-time decisional guidance; however, its impact on neonatal health outcomes is unknown. Mobile WACh NEO (MWACh NEO) was a parallel, unblinded and individually randomized controlled trial at six health facilities across Kenya. Pregnant women at 28-36 weeks gestation were randomized (1:1) to the MWACh NEO intervention or standard of care. MWACh NEO delivered automated maternal and neonatal health text messages to participants up to 6 weeks postpartum and allowed free text communication with a nurse. This trial sought to determine if text communication decreased neonatal mortality. The analysis was intention to treat. From September 2020 until June 2022, 5,020 participants were enrolled and randomized. One hundred and thirty-six participants were excluded because of incomplete mortality data, leaving 2,442 participants in each group for the analysis. Eighty-three neonatal deaths occurred for a neonatal mortality rate of 18.8 per 1,000 live births in the intervention group and 15.2 per 1,000 live births in the control group, with a risk ratio of 1.25 (0.81, 1.91), P = 0.31. No adverse events related to the intervention were reported. Text communication did not decrease neonatal mortality compared to standard of care. Most neonates died before discharge from the facility. ClinicalTrials.gov registration: NCT04598165 .

BACKGROUND:Plant-based diets are associated with a lower risk of cardiovascular disease (CVD). Proteomics may improve our understanding of the biological pathways underlying these associations. OBJECTIVES/OBJECTIVE:Using large-scale proteomics, we aimed to examine if plant-based diet-related proteins, which have been previously identified, are associated with incident CVD and subtypes of CVD in the Atherosclerosis Risk in Communities (ARIC) Study and Framingham Heart Study (FHS) Offspring cohort. METHODS:Discovery analyses were based on 9,078 participants free of CVD at ARIC visit 3 (1993-1995). Cox proportional hazards regression was used to evaluate the associations between plant-based diet-related proteins and incident CVD, coronary heart disease, heart failure, and stroke. Replication analyses were based on 1,279 participants without CVD in FHS Offspring cohort. RESULTS:In the ARIC Study, over a median follow-up of 21 years, there were 3,167 CVD events. At a false discovery rate (FDR) <0.05, 26 out of 73 plant-based diet-related proteins were significantly associated with incident CVD, after adjusting for important confounders. 18, 1, and 0 proteins were associated with heart failure, stroke, and coronary heart disease, respectively. Three, and 2 additional proteins were associated with CVD, and heart failure risk in FHS Offspring cohort at the nominal threshold (p value <0.05). Soluble advanced glycosylation end product-specific receptor (AGER) was inversely associated with incident CVD whereas thrombospondin-2 (THBS2) and N-terminal pro-BNP (NT-proBNP) was positively associated with incident CVD. THBS2 was positively associated with incident heart failure, whereas neuronal growth factor regulator 1 (NEGR1) and insulin-like growth factor-binding protein 1 (IGFBP1) was inversely associated. CONCLUSION/CONCLUSIONS:These proteins highlight several pathways that could explain plant-based diets-CVD associations.

BACKGROUND:Hearing loss is prevalent in older adults and is associated with reduced daily physical activity, but whether hearing intervention attenuates declines in physical activity is unknown. We investigated the 3-year effect of a hearing intervention versus a health education control on accelerometer-measured physical activity in older adults with hearing loss. METHODS:This secondary analysis of the ACHIEVE randomized controlled trial included 977 adults aged 70-84 years with hearing loss. Participants were randomized to either a hearing intervention group or a health education control group. Physical activity was measured using wrist-worn accelerometers at baseline, 1, 2, and 3 years. Linear mixed models assessed the impact of the intervention on changes in total activity counts, active minutes per day, and activity fragmentation. RESULTS:Among 847 participants in the final analysis (mean age 76.2 years; 440 [52%] women; 87 [10%] Black; 5 [0.8%] Hispanic), total activity counts declined by 2.7% annually, and active minutes/day declined by 2.1% annually over 3 years in both intervention and control groups. Activity patterns also became more fragmented over time. No appreciable differences were observed between hearing intervention and health education control in the 3-year change in accelerometry-measured physical activity measures. CONCLUSIONS:Hearing intervention did not appreciably attenuate 3-year declines in physical activity compared to health education control in older adults with hearing loss. Alternative strategies beyond hearing treatment may be needed to enhance physical activity among older adults with hearing loss.
