Although it is known that caregiver dietary behaviors influence child eating patterns, a gap remains in addressing the diet of a caregiver as much as their child in pediatric practice. A dyadic (caregiver-child) dietary approach would enhance the promotion of healthy eating patterns in children (and their caregivers) and achieve the population health goal of healthy eating across demographic groups. This study aimed to understand factors influencing dyadic dietary patterns (concordance, discordance) and contexts. Twenty professionals who provide nutrition-related expertise for families were recruited via maximum variation sampling. Qualitative thematic analysis of semi-structured interviews revealed 3 themes: (1) variable professional perspectives on what constitutes "healthy eating," (2) eating patterns of a child in the setting of variable caregiver eating practices, and (3) challenges to the promotion of a healthy caregiver-child dyadic diet within a social context. The results offer insight for future interventions that promote positive intergenerational transmission of health.

BACKGROUND/OBJECTIVES/OBJECTIVE:Patients often face uncertainty about what they should know after prostate cancer diagnosis. Web-based information is common but is at risk of being of poor quality or readability. SUBJECTS/METHODS/METHODS:We used ChatGPT, a freely available Artificial intelligence (AI) platform, to generate enquiries about prostate cancer that a newly diagnosed patient might ask and compared to Google search trends. Then, we evaluated ChatGPT responses to these questions for clinical appropriateness and quality using standardised tools. RESULTS:ChatGPT generates broad and representative questions, and provides understandable, clinically sound advice. CONCLUSIONS:AI can guide and empower patients after prostate cancer diagnosis through education. However, the limitations of the ChatGPT language-model must not be ignored and require further evaluation and optimisation in the healthcare field.

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.

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 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.

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: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.
