More than 6 million persons living with dementia (PLWD) in the United States rely on the emergency department (ED) for unscheduled care, with up to half discharged home after treatment. The ED-to-home transition poses significant challenges for PLWD and their care partners (referred to as "dyads"), contributing to high rates of ED revisits and adverse outcomes. The Community Paramedic-led Transitions Intervention (CPTI) was developed to address these challenges by adapting the validated Care Transitions Intervention for the ED setting. Delivered by trained community paramedics, CPTI is a short-term 30-day program that includes one home visit and up to three follow-up phone calls. Using a coaching model, paramedic coaches work with members of the dyad to strengthen their knowledge, skills, and confidence to manage their health and successfully navigate the health care system. CPTI is being implemented as part of Emergency Departments LEading the Transformation of Alzheimer's and Dementia Care (ED-LEAD), a cluster-randomized pragmatic trial testing 3 interventions designed to improve outcomes for PLWD discharged home from the ED across 14 health systems and 79 EDs nationwide. This paper describes the CPTI model as implemented within ED-LEAD, detailing its theoretical foundation, structure, training curriculum, workflow integration, and implementation monitoring. This framework can provide a model for health systems, provider groups, and emergency medical service agencies interested in adopting this innovative approach and implementing the CPTI. Insights from its implementation within ED-LEAD will guide future efforts to improve post-ED outcomes and continuity of care for PLWD and their care partners.

One in four US adults age ≥ 65 have two or more chronic conditions, many of which can be prevented or managed through nutritional interventions. Despite known benefits, nutrition is not prioritized in undergraduate or graduate medical education. We reviewed agendas of three major geriatrics-related continuing medical education (CME) conferences from 2018 to 2025 to understand the extent to which deficits in nutrition training could be addressed via CME. We searched 19 conference agendas for the terms: "nutrition," "diet," "lifestyle," "food," "fat," "carbohydrates," "protein," "vitamin," "mineral," "weight," and "nutrients." Our results showed that nutrition topics were inconsistently offered at geriatrics-related CME conferences, with some conferences offering no nutrition-related talks, and some offering as little as 8 minutes of nutrition-related talks. Few sessions addressed malnutrition or food security. This is the first known review of nutrition education at geriatrics-focused CME conferences. We found insufficient practical nutrition education for providers at CME events to overcome training gaps in medical education. Improved interdisciplinary participation at CME events could increase availability of nutrition education for physicians.

Reliable structural brain measurements are essential for studying neurodegeneration and for designing adequately powered aging and Alzheimer's disease (AD) research. We evaluated the test-retest reliability of FreeSurfer 7.1 morphometric measures in 100 older adults (mean age 73.5 years) ranging from cognitively unimpaired to dementia. Each participant underwent two T1-weighted 3T MRI scans on the same scanner within a short interval (mean 5.5 weeks), minimizing biological change. Segmentation was performed in both standard cross-sectional and longitudinal FreeSurfer modes, focusing on AD-relevant volumes of entorhinal cortex, hippocampus, lateral ventricles, choroid plexus, and the AD cortical thickness signature. Reliability was quantified using absolute and root-mean-square test-retest differences, standard deviation of differences, and intraclass correlation coefficients. Longitudinal processing improved precision by 15-50% across most measures compared with cross-sectional processing, with the largest gain observed for entorhinal thickness. Larger, anatomically well-defined regions (e.g., hippocampus, AD signature) demonstrated higher reliability than small structures or those with complex geometry (e.g., entorhinal cortex, choroid plexus). Image quality, indexed by the Euler characteristic, was the only factor significantly associated with measurement variability; reliability was unrelated to age, sex, cognitive status, inter-scan interval, or amyloid/tau PET burden. Power analyses indicated that detecting a 1% within-individual change requires sample sizes ranging from 36 (AD signature) to >300 (entorhinal cortex). We observed low reliability of choroid plexus volumetry by FreeSurfer 7. These results provide practical benchmarks for expected FreeSurfer measurement variability in older adults. They highlight the advantages of longitudinal processing and rigorous quality control for research on brain aging and AD.

INTRODUCTION/BACKGROUND:Neutrophil-to-lymphocyte ratio (NLR), a marker of systemic inflammation, has been linked to dementia risk, but prior studies were limited by small sample sizes. METHODS:We assessed the association between baseline NLR and incident Alzheimer's disease (AD) and Alzeimer's disease and related dementias (AD/ADRD) using electronic health records from New York University (NYU) (n = 284,530) and the Veterans Health Administration [VA] (n = 85,836) Hospitals from 2011 to 2023. AD/ADRD diagnoses were identified via International Classification of Diseases (ICD) codes ≥6 months post-baseline. Cox models and cumulative incidence functions (CIFs) adjusted for demographic and clinical variables, with death as a competing risk. RESULTS:Higher NLR was associated significantly with increased AD/ADRD risk in both cohorts (NYU hazard ratio [HR] = 1.07, 95% confidence interval [CI] 1.02-1.15; VA HR = 1.21, 95% CI 1.10-1.34). Spline analysis further confirmed a continuous dose-response relationship, and subgroup analyses showed higher risk among female and Hispanic patients. DISCUSSION/CONCLUSIONS:Elevated NLR is independently associated with higher AD/ADRD risk across diverse populations, highlighting the role of systemic inflammation and neutrophil-mediated pathways in neurodegeneration.

BACKGROUND:Age-related hearing loss is common and a particularly prevalent disability among Veterans. In response, comprehensive hearing services are available within the Veterans Affairs (VA) integrated healthcare system. Severe hearing loss may pose distinct communication challenges inadequately addressed by hearing aids, but data suggest severe hearing loss is often not treated differently. We sought to identify barriers and facilitators to evidence-based and individualized management of severe hearing loss from the perspectives of VA clinicians and Veterans. METHODS:We used purposeful sampling to conduct remote semi-structured video interviews with 33 current VA clinicians encompassing multiple disciplines and 39 Veterans with severe hearing loss over approximately an 18 month period (May 2022 to December 2023). We analyzed qualitative data using content thematic analysis. Coding categories were summarized within each participant; then across all participants to yield clinician-specific and Veteran themes. RESULTS:In the sample of 33 VA clinicians (20 audiologists, 9 otolaryngologists and 4 primary care clinicians), the overarching theme of qualitative data is that hearing loss is undertreated in the Veteran population. Across clinician groups, the qualitative data revealed multi-level factors (system-, clinician-, and patient-level) that influence the delivery of hearing care and management for Veterans with severe hearing loss. Interviews revealed that efficient access and collaborative care facilitate evidence-based practice. Among Veterans, inadequately managed hearing loss impacts quality of life; lack of knowledge and misconceptions about hearing care options and system-level barriers influence Veterans' perceptions of their hearing care and management. CONCLUSION/CONCLUSIONS:Although hearing care is available to Veterans, multi-level factors influence the delivery of hearing care and management for Veterans with severe hearing loss. Greater attention both in primary and specialty care is needed to ensure tailored treatments are available to Veterans with severe hearing loss across the integrated VA health care system.

RATIONALE & OBJECTIVE/UNASSIGNED:Randomized controlled trials (RCTs) show that integrated palliative care can improve symptoms compared with usual care in many serious illnesses, yet there are no comparable RCTs in chronic kidney disease (CKD). STUDY DESIGN/UNASSIGNED:We conducted a pilot feasibility RCT comparing kidney palliative care (KPC) integrated with CKD care with usual CKD care. SETTING & PARTICIPANTS/UNASSIGNED:English and Spanish speakers aged ≥18 years with CKD stage IV and V, or receiving dialysis, seen at an urban safety-net hospital. EXPOSURES/UNASSIGNED:Participants were randomized to usual CKD care or to usual CKD care plus 6-monthly ambulatory KPC visits. OUTCOMES/UNASSIGNED:Primary outcomes were feasibility of recruitment, retention, intervention delivery, and data collection. Secondary outcomes included change in symptom burden at 6 months, measured by the Integrated Palliative Outcome Scale (IPOS)-Renal (lower scores represent lower burden), quality of life measured by the Kidney Disease Quality of Life 36-item survey, and engagement in advance care planning. ANALYTICAL APPROACH/UNASSIGNED:Feasibility outcomes are reported as proportions and clinical outcomes as descriptive summaries of change in scores. RESULTS/UNASSIGNED:Of the 146 people approached, 84 (56%) consented, 75 (89%) were randomized, and 57 (76%) completed the trial. 56% of participants were Hispanic and 32% were Black, with 49% on Medicaid and 13% uninsured. The mean age of participants was 61 years, and 31% were receiving dialysis. A mean of 4-6 intervention visits was attended. At 6 months, the intervention group had a 4.1-point decrease in IPOS score (standard deviation 13.4), whereas the mean IPOS score of the control group increased by 0.6 points (standard deviation 7.8) from baseline. LIMITATIONS/UNASSIGNED:Small sample size and limited number of providers to assess generalizability. CONCLUSIONS/UNASSIGNED:We demonstrate the feasibility of an RCT comparing integrated KPC with usual CKD care in a safety-net hospital. Although this study was not powered to detect significance in change of clinical outcomes, our findings suggest that there is value in testing KPC in efficacy trials and that these are feasible.

Over 50% of persons living with dementia (PLWD) and their care partners (dyads) visit the emergency department (ED) every year. In the ED, healthcare professionals face complex challenges managing acute issues and symptoms of Alzheimer's disease and Alzheimer's disease-related dementias without provider training or in-ED structures to ensure a successful discharge. While many of these visits are for conditions more suitable for ambulatory care, as many as 50% of PLWD discharged from the ED return within 30 days, suggesting opportunities to improve ED care, and discharge processes. Emergency Care Redesign (ECR) includes intentional workflows where physicians, nurses, and social workers engage in a team-based approach with structured assessments to manage a myriad of potential psychosocial and behavioral issues contributing to the need for ED care. Three core components comprise this evidence-based, efficient pragmatic intervention for PLWD and their care partners: (1) problem identification, (2) problem prioritization, and (3) provision of non-pharmacologic solutions supported by community resources. Although these components are essential to provide optimal ED care and reduce revisits and other adverse outcomes, they require an embedded clinical decision support structure, focused training, and clear workflows. In this paper, we describe the ECR intervention as one of three being implemented in the cluster-randomized multifactorial pragmatic trial, Emergency Departments LEading Transformation of Alzheimer's and Dementia Care (ED-LEAD), designed to improve care for PLWD and their outcomes after discharge home within 15 health systems and 79 EDs across the United States.

BackgroundPersons living with dementia (PLWD) and their care partners face unique challenges in participating in research studies. Community Engagement Studios (CES) provide a framework for researchers to work directly with community members, considered as Community Experts, who experience conditions under study to enhance research design, implementation, and dissemination.ObjectiveWe describe our experience conducting CES with PLWD and their care partners and lessons learned.MethodsPLWD and their care partners participated in three CES between July and December 2022; one in New Hampshire in English and two in New York, one of which was in Spanish. We followed the CES Toolkit guidance, which involves 1) inviting experts/stakeholders (PLWD and their care partners) to a consultative meeting, 2) preparing a presentation (interview guide) and facilitating the meeting, and 3) receiving and analyzing feedback from participants.Results12 community members (6 PLWD and 6 care partners) participated in our three studios. Three study design factors were identified during the CES: recruitment process (trust and communication with the research team), participants' autonomy, and trust and communication with clinicians. Spanish language community members raised similar issues to those in the English-speaking CES. However, Spanish language participants also noted the potential impact of interpreters during clinic visits.ConclusionsCES were feasible, informative, and well-received by PLWD and led to changes in our study design. We describe strategies for engaging care partners and PLWD, Community Experts, to elicit valid and valuable recommendations for making research studies more relevant and impactful.

INTRODUCTION/BACKGROUND:Though brain fog is common in Long-coronavirus disease 2019 (Long-COVID), the incidence of mild cognitive impairment (MCI) is unknown. METHODS:In an observational cohort study, recovered COVID-positive, Long-COVID, and COVID-negative subjects underwent blinded evaluation using National Alzheimer's Coordinating Center (NACC) and National Institute on Aging (NIA) -Alzheimer's Association diagnostic criteria for dementia and MCI. The cumulative incidence of MCI was calculated for each group, and the hazard of MCI was compared between groups. RESULTS:Among 260 subjects, the cumulative incidence of MCI over 4.4 years was higher with Long-COVID (27%) versus recovered-COVID (5%) or COVID-negative status (1%). There was a higher hazard of MCI for patients with Long-COVID compared to those without (hazard ratio [HR] 3.93, 95% confidence interval [CI] 1.86-8.31, p < 0.001), and specifically for the Alzheimer's disease (AD) -related MCI subtype (HR 3.20, 95% confidence interval [CI] 1.14-9.00, p = 0.027). DISCUSSION/CONCLUSIONS:The cumulative incidence and adjusted hazard of MCI (and specifically AD-related MCI) at 4.4 years was significantly higher among Long-COVID patients compared to recovered-COVID and COVID-negative controls.

BACKGROUND:Age-related hearing loss is highly prevalent, underrecognized, and consequently, undertreated. Hearing loss can have a substantial negative impact on communication and biopsychosocial health. We hypothesize that offering validated hearing assessments and a point-of-care counseling program in an older, underserved population will be more accessible and acceptable than the traditional pathway for audiology care, particularly in marginalized communities. METHODS:This convergent mixed methods feasibility study will assess the implementation of a hearing program embedded in a quality improvement initiative within the Geriatric Clinic of New York City Health and Hospital's Bellevue Hospital Center and the feasibility of recruiting for a future efficacy trial to test the intervention. Adult patients ≥ 60 years who are proficient in English or Spanish and not currently using hearing rehabilitation are eligible for initial screening. Hearing level, including individual ear severity, is identified using a validated tablet-based measure of pure tone audiometry and a self-report measure of hearing disability. We define hearing loss subjectively based on a score of 8 or greater on the Hearing Handicap Inventory-Screen (HHI-S) or using a four-frequency pure tone average > 25 dB hearing level in the better ear, representing at least a mild hearing loss. Patients who are determined to have measurable hearing loss and provide informed consent will be invited to participate in a pilot study and randomized to one of two approaches: (1) a counseling on alternative rehabilitation strategies intervention arm or (2) usual care with referral to the audiology pathway. Primary feasibility outcomes include recruitment and retention rates, intervention adherence, acceptability, and the ability to collect outcome measurements. We will also explore changes in HHI-S scores over 3 months and assess subsequent audiology service utilization in both groups. In addition to the quantitative data, we will include key participant interviews with staff and patients to assess feasibility from participant attitudes. DISCUSSION/CONCLUSIONS:This study will provide insights into the feasibility of offering hearing screening/assessments and counseling in primary care and its potential to improve access to hearing care for underserved older adults. Findings will inform the design of future trials evaluating the impact of primary care-based tailored hearing interventions on patient health and quality of life.
