Examining cognitive accessibility of the VIA Inventory of Strengths for adults with intellectual disability.

BACKGROUND: We evaluated cognitive accessibility of the VIA Inventory of Strengths Youth short form with adults with intellectual disability for use in strengths-based practice. METHODS: We conducted cognitive testing with adults with intellectual disability (n = 33; M age = 36.2; range: 20.4-64.2). Data were coded for the extent to which (1) items were interpreted correctly; (2) participants endorsed items as describing themselves. We calculated descriptive statistics to evaluate item interpretation and response scale use. RESULTS: On average, 59% of participants interpreted items correctly, 20% misinterpreted items, 14% had mixed interpretations. Positive item endorsement was most associated with the response 'Very much like me' (77%); mixed endorsement was most associated with 'Somewhat like me' (39%); and negative endorsement of items was most associated with 'Not at all like me' (54%). CONCLUSIONS: Revisions are necessary for several items to improve accessibility for adults with intellectual disability and should be made in collaboration with this population.

A Call-In for Allyship and Anti-Ableism in Intellectual Disability Research.

Provoked by decades of grassroots activism, anti-ableist work is underway to advance disability rights. Intellectual disability (ID) researchers can integrate these social changes into their work by interrogating and transforming the beliefs and practices that underpin ID research. We share actionable ideas to foster anti-ableism and allyship in ID research. These include: (1) Learn from and nurture long-term, mutual relationships with people with ID; (2) Amplify the voices of people with ID in institutional structures that influence research; (3) Infuse anti-ableist frameworks into our own research; and (4) Embody a career-long commitment to disability rights, reflexive practice, and growth.

Deciphering the "Art" in Modeling and Simulation of the Knee Joint: Assessing Model Calibration Workflows and Outcomes.

Model reproducibility is a point of emphasis for the National Institutes of Health (NIH) and in science, broadly. As the use of computational modeling in biomechanics and orthopedics grows, so does the need to assess the reproducibility of modeling workflows and simulation predictions. The long-term goal of the KneeHub project is to understand the influence of potentially subjective decisions, thus the modeler's "art", on the reproducibility and predictive uncertainty of computational knee joint models. In this paper, we report on the model calibration phase of this project, during which five teams calibrated computational knee joint models of the same specimens from the same specimen-specific joint mechanics dataset. We investigated model calibration approaches and decisions, and compared calibration workflows and model outcomes among the teams. The selection of the calibration targets used in the calibration workflow differed greatly between the teams and was influenced by modeling decisions related to the representation of structures, and considerations for computational cost and implementation of optimization. While calibration improved model performance, differences in the postcalibration ligament properties and predicted kinematics were quantified and discussed in the context of modeling decisions. Even for teams with demonstrated expertise, model calibration is difficult to foresee and plan in detail, and the results of this study underscore the importance of identification and standardization of best practices for data sharing and calibration.

'Being a part of something': Experiences and perceived benefits of young adult peer mentors with intellectual/developmental disabilities and co-occurring mental health conditions.

BACKGROUND: Peer-provided services are a common model for addressing mental health concerns. Peer providers report a range of benefits and challenges associated with their role. However, there is little information about the experiences of peer providers with intellectual/developmental disabilities. AIM: To explore the experiences of young adult peer-providers with intellectual/developmental disabilities in the context of a mental health intervention. METHODS: We conducted interviews with four young adults with intellectual/developmental disabilities and their parents and teachers to understand their experiences providing a peer mentoring mental health intervention. RESULTS: Young adult peer mentors perceived themselves as responsible for maintaining the mentoring relationship, delivering the intervention and acting as helpers and independent professionals. The experiences of young adult peer mentors were driven by the temporal, institutional and social contexts of their work. Peer mentoring was an enjoyable, social activity. Mentors, parents and teachers emphasised how taking on the peer mentoring role during the transition to adulthood and within the capital-rich university context led to a sense of pride and professional development. Further, these contexts may have led mentors to emphasise their intervention-delivery, helper and professional roles over relationship maintenance. DISCUSSION & CONCLUSION: Context may shape the perceived roles and benefits for young adult peer mentors with intellectual/developmental disabilities.

Developing and evaluating a toolkit of strategies to support remote inclusive research teams.

Research teams must collaborate with people with intellectual and developmental disabilities to identify effective and inclusive responses to the COVID-19 pandemic and other public health emergencies. Collaborating remotely requires telecommunication and other technologies. We designed and evaluated a digital "Toolkit for Remote Inclusive Research" to provide research teams with evidence-informed strategies to make remote research accessible to and inclusive of people with intellectual and developmental disabilities. First, we completed a rapid scoping review to identify technology used by people with intellectual and developmental disabilities on collaborative research teams. Second, we designed a digital toolkit featuring 23 strategies identified in the review. Third, six inclusive researchers evaluated the toolkit. We illustrate how our team used these evidence-informed strategies during the past year to develop this and other tools to support inclusive research.

Anticipating the outcomes: how young adults with developmental disabilities and co-occurring mental health conditions make decisions about disclosure of their mental health conditions at work.

PURPOSE: Little is known about how young adults (YA) with developmental disabilities (DD) and co-occurring mental health conditions navigate workplace disclosure of their mental health condition(s). We sought to understand the guidance professionals provide regarding disclosure and the decisions YA makes about disclosure of mental health conditions. METHODS: We conducted focus groups with professionals who support YA with DD to attain and maintain employment (n = 17) and individual interviews with YA with DD and co-occurring mental health conditions (n = 12; DD diagnoses: autism, n = 9, other DD, n = 3). We conducted content analysis to identify why, when, what, and to whom YA disclose their mental health condition and guidance provided regarding disclosure. RESULTS: YA and professionals described disclosure decisions as largely influenced by perceived needs (i.e., need for accommodations) and anticipated positive (e.g., support) and negative (e.g., stigma, not being hired) outcomes. They largely constrained disclosure to work-relevant content. Many YA disclosed to coworkers with whom they were comfortable, though both YA and professionals agreed that initial disclosure should be limited to supervisors and/or human resources. CONCLUSIONS: Workplaces may support disclosure-a necessity for the provision of accommodations-by cultivating an inclusive environment and openly demonstrating familiarity and comfort with employees with disabilities.IMPLICATIONS FOR REHABILITATIONProfessionals who support young adults with developmental disabilities and co-occurring mental health conditions should be well-versed in current laws and regulations on disclosure and reasonable workplace accommodations.Workplace culture is one major factor impacting how disclosure is handled, including whether the disclosure is required at all.Individuals with disabilities and professionals should recognize that timing, content, and decisions to disclose may vary by individuals' needs and workplace supports, and that change may occur over time.

Assessment of reporting practices and reproducibility potential of a cohort of published studies in computational knee biomechanics.

Reproducible research serves as a pillar of the scientific method and is a foundation for scientific advancement. However, estimates for irreproducibility of preclinical science range from 75% to 90%. The importance of reproducible science has not been assessed in the context of mechanics-based modeling of human joints such as the knee, despite this being an area that has seen dramatic growth. Framed in the context of five experienced teams currently documenting knee modeling procedures, the aim of this study was to evaluate reporting and the perceived potential for reproducibility across studies the teams viewed as important contributions to the literature. A cohort of studies was selected by polling, which resulted in an assessment of nine studies as opposed to a broader analysis across the literature. Using a published checklist for reporting of modeling features, the cohort was evaluated for both "reporting" and their potential to be "reproduced," which was delineated into six major modeling categories and three subcategories. Logistic regression analysis revealed that for individual modeling categories, the proportion of "reported" occurrences ranged from 0.31, 95% confidence interval (CI) [0.23, 0.41] to 0.77, 95% CI: [0.68, 0.86]. The proportion of whether a category was perceived as "reproducible" ranged from 0.22, 95% CI: [0.15, 0.31] to 0.44, 95% CI: [0.35, 0.55]. The relatively low ratios highlight an opportunity to improve reporting and reproducibility of knee modeling studies. Ongoing efforts, including our findings, contribute to a dialogue that facilitates adoption of practices that provide both credibility and translation possibilities.

Psychometric testing of the Icelandic Occupational Self-Assessment (OSA-IS).

BACKGROUND: The Occupational Self-Assessment (OSA) is a self-report measure of occupational competence and values used to identify goals and assess outcomes. The Icelandic version of the OSA (OSA-IS) has been through several developmental stages to evaluate its psychometric properties. Through each stage, revisions have been made. AIM: To investigate the psychometric properties of the fourth revised version of OSA-IS. MATERIALS AND METHODS: Retrospective data from 291 rehabilitation clients with a range of conditions were analysed using Rasch analysis of unidimensionality and descriptive statistics. All statistics were compared to established criteria. RESULTS: Analyses suggest the OSA-IS items define unidimensional constructs of occupational competence and values. Most (89%) participants completed the assessment in a reliable manner and no association was observed between demographic variables and fit status. Differences in the item hierarchies were observed between the original OSA and the OSA-IS, suggesting that Icelandic clients responded differently due to cultural, linguistic and/or sample differences. CONCLUSION AND SIGNIFICANCE: OSA-IS is a psychometrically sound instrument that may be used to support identification of client-centred goals and for intervention development. Clinicians should use score tables specifically developed for the OSA-IS to measure outcomes.

Open Knee(s): A Free and Open Source Library of Specimen-Specific Models and Related Digital Assets for Finite Element Analysis of the Knee Joint.

There is a growing interest in the use of virtual representations of the knee for musculoskeletal research and clinical decision making, and to generate digital evidence for design and regulation of implants. Accessibility to previously developed models and related digital assets can dramatically reduce barriers to entry to conduct simulation-based studies of the knee joint and therefore help accelerate scientific discovery and clinical innovations. Development of models for finite element analysis is a demanding process that is both time consuming and resource intensive. It necessitates expertise to transform raw data to reliable virtual representations. Modeling and simulation workflow has many processes such as image segmentation, surface geometry generation, mesh generation and finally, creation of a finite element representation with relevant loading and boundary conditions. The outcome of the workflow is not only the end-point knee model but also many other digital by-products. When all of these data, derivate assets, and tools are freely and openly accessible, researchers can bypass some or all the steps required to build models and focus on using them to address their research goals. With provenance to specimen-specific anatomical and mechanical data and traceability of digital assets throughout the whole lifecycle of the model, reproducibility and credibility of the modeling practice can be established. The objective of this study is to disseminate Open Knee(s), a cohort of eight knee models (and relevant digital assets) for finite element analysis, that are based on comprehensive specimen-specific imaging data. In addition, the models and by-products of modeling workflows are described along with model development strategies and tools. Passive flexion served as a test simulation case, demonstrating an end-user application. Potential roadmaps for reuse of Open Knee(s) are also discussed.

Eligibility criteria in NIH-funded clinical trials: Can adults with intellectual disability get in?

BACKGROUND: Although scientific breakthroughs can promote health equity, there is concern that adults with intellectual disability, a health disparities population, may be excluded from clinical trials. OBJECTIVE: To determine the extent to which adults with intellectual disability are subject to exclusion from National Institutes of Health (NIH)-funded clinical trials. METHODS: We studied recent NIH-funded Phase 2/3, 3, and 4 clinical trials of United States-based working-age adults (>18 < 55 years of age) listed in ClinicalTrials.gov. We coded eligibility criteria for inclusion, direct exclusion, and indirect exclusion of adults with intellectual disability. RESULTS: We rarely identified studies that directly include adults with intellectual disability. Most studies (74.6%) had eligibility criteria that directly and/or indirectly exclude adults with intellectual disability. Approximately one-third of studies had direct exclusion criteria based on cognitive impairment or diagnosis of intellectual disability. Nearly 65% of studies indirectly excluded adults with intellectual disability based on factors likely associated with intellectual disability (e.g., functional capacity, inability to read/write, and/or research staff discretion). CONCLUSIONS: We found less exclusion based on diagnosis of intellectual disability than anticipated. Nonetheless, about three-fourths of studies had eligibility criteria which would likely lead to the direct and/or indirect exclusion of adults with intellectual disability. Our findings suggest substantial cause for concern that adults with intellectual disability experience widespread exclusion from NIH-funded clinical trials-exclusion that may lack appropriate justification and assessment. Consequently, this group is denied equal access to the potential benefits of scientific discovery. We provide recommendations for approaches to include adults with intellectual disability.

Supporting young adults with intellectual/developmental disabilities to deliver a peer mentoring intervention: Evaluating fidelity and resources required.

BACKGROUND: Peer-delivered interventions are a best practice in mental health, yet no such intervention exists for young adults (YA) with intellectual/developmental disabilities with co-occurring mental health conditions. We evaluated YA with intellectual/developmental disabilities' ability to deliver a novel peer mentoring intervention with fidelity and the supports received. METHODS: We coded audio-recorded mentoring sessions to evaluate if 4 mentors adhered to 'content' (e.g., psychoeducation) and 'quality' (e.g., validation) fidelity criteria (codes: yes/no). We conducted content analysis of mentor support logs and interviews with mentors', mentors' parents and teachers to describe the supports mentors received. RESULTS: Average fidelity for content criteria (M = 73.3%) was higher than quality criteria (M = 60.0%). Weekly support addressed logistics, delivering content, interpersonal interactions, emotional support, professionalism, and organisation. Family members and teachers rarely provided additional support. CONCLUSIONS: With support, YA can deliver a peer mentoring intervention addressing mental health. Additional training activities will be developed to improve fidelity.

How people with intellectual and developmental disabilities on collaborative research teams use technology: A rapid scoping review.

BACKGROUND: We conducted a rapid scoping review to identify how inclusive research teams use technology during the research process that could support remote collaboration during public health emergencies like the COVID-19 pandemic. METHOD: We searched three databases and conducted a hand search. Two independent reviewers screened 1498 abstracts and titles for inclusion criteria; 81 full text articles were further reviewed; 47 were included. We extracted information about each type of technology, categorised technology used during the research process, and documented described accommodations. RESULTS: We identified 47 articles and 94 examples of technologies used by people with intellectual and developmental disabilities throughout the research process: team formation and team function (38), data collection (19), data analysis (17) and dissemination (20). CONCLUSIONS: Technology use by team members with intellectual and developmental disabilities demonstrates promise for remote research collaborations during public health and climate emergencies and teams with members living in diverse locations.

Predictors of community-based employment for young adults with intellectual disability and co-occurring mental health conditions.

PURPOSE: To identify predictors of community-based employment and employment quality for young adults ages 23-30 with intellectual disability and co-occurring mental health conditions (YA-ID-MH). METHODS: We conducted secondary analysis of the 2017-2018 National Core Indicators® (NCI®) In-Person Survey. The NCI® survey was conducted in 35 states and Washington DC. Participants: YA with ID, ages 23-30 who had complete data. We conducted multiple regression analyses to examine demographic and environmental predictors of community-based employment, in addition to employment quality indicators: hourly wages, hours worked, and job duration. We also descriptively examined job satisfaction. RESULTS: YA-ID-MH were somewhat less likely to be employed per record review and self-report than YA with ID only, but these findings did not reach statistical significance. On average, YA with ID only had higher hourly wages and worked more hours than those with ID-MH, but there were no significant differences in job duration. For YA-ID-MH, predictors of employment included gender, race, level of ID, and residential setting. Multiple demographic and environmental factors predicted employment quality. CONCLUSIONS: YA-ID-MH experience employment disparities compared to YA with ID only. Service providers should specifically attend to those at the highest risk of unemployment/low quality employment.IMPLICATIONS FOR REHABILITATIONYoung adults with intellectual/developmental disabilities and co-occurring mental health conditions (ID-MH) experience employment disparities.Young adults with ID-MH who are non-white and female may have particularly low employment rates and employment quality.Societal-level interventions to address racial and gender-based bias may support individuals with ID-MH to acquire and maintain jobs by addressing disparities in social networks/social capital and ensuring equitable service provision and supports for those at the highest risk for unemployment.Policy makers should consider additional funding for employment services for transition-age youth with ID-MH, particularly those from marginalized populations.

A Method to Compare Heterogeneous Types of Bone and Cartilage Meshes.

Accurately capturing the bone and cartilage morphology and generating a mesh remains a critical step in the workflow of computational knee joint modeling. Currently, there is no standardized method to compare meshes of different element types and nodal densities, making comparisons across research teams a significant challenge. The aim of this paper is to describe a method to quantify differences in knee joint bone and cartilages meshes, independent of bone and cartilage mesh topology. Bone mesh-to-mesh distances, subchondral bone boundaries, and cartilage thicknesses from meshes of any type of mesh are obtained using a series of steps involving registration, resampling, and radial basis function fitting after which the comparisons are performed. Subchondral bone boundaries and cartilage thicknesses are calculated and visualized in a common frame of reference for comparison. The established method is applied to models developed by five modeling teams. Our approach to obtain bone mesh-to-mesh distances decreased the divergence seen in selecting a reference mesh (i.e., comparing mesh A-to-B versus mesh B-to-A). In general, the bone morphology was similar across teams. The cartilage thicknesses for all models were calculated and the mean absolute cartilage thickness difference was presented, the articulating areas had the best agreement across teams. The teams showed disagreement on the subchondral bone boundaries. The method presented in this paper allows for objective comparisons of bone and cartilage geometry that is agnostic to mesh type and nodal density.

Inclusive approaches to developing content valid patient-reported outcome measure response scales for youth with intellectual/developmental disabilities.

BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly used in health care to evaluate service quality and client progress. Response scales are a critical component of PROM content validity and must be designed to be relevant and comprehensible by users. METHODS: In collaboration with eight youth co-researchers with intellectual/developmental disabilities ages 14-21, we used an iterative, three-stage approach to develop and select a response scale for the PEDI-PRO. Stages: 1) inclusive development of response scale options; 2) Collecting data about response scale options during focus groups with youth with intellectual/ developmental disabilities (n = 62); and 3) Analysing data to refine response options. RESULTS: Through two cycles of the three-stage process, the inclusive research approach led to the development of a content valid response scale that describes functional performance of everyday activities ("very easy," "a little easy," "a little hard"). CONCLUSION: An inclusive research approach can support the development of content valid PROM scales. We identified four broad strategies that supported youth co-researchers to engage in this response scale development process: universal design for learning, use of lived experiences, breaking down tasks, and peer support. Researchers may adopt and/or adapt the accessible inclusive research approaches described in this manuscript for measurement development and other research projects.

Impact of COVID-19 on services for people with disabilities and chronic health conditions.

BACKGROUND: People with disabilities and chronic health conditions rely on a range of services and supports to complete daily tasks, maintain health, and participate in the community. Preliminary research suggests the COVID-19 pandemic greatly disrupted these services and this population may be particularly susceptible to unemployment. OBJECTIVE: Describe employment and service disruptions for individuals with disabilities and chronic health conditions during the onset of community-based spread of COVID-19 in the United States. METHODS: Adults with disabilities and chronic health conditions completed online surveys to report employment and service changes via multiple choice and open-ended questions. Multiple choice questions were analyzed using descriptive statistics; open-ended responses were coded using content analysis. RESULTS: Participants (n = 109): 79.8% female, 88.1% white, 77.121% completed a 4-year college degree or greater, 61.4% had annual income ≥$45,000. Only 14.9% of survey respondents reported disruptions in employment. On average, 54.0% of service changes were due to discontinuation, including loss of physical therapy, job coaching, community organizations, transportation, and peer supports. Other changes included a shift to virtual service delivery and family members taking the role of service providers. CONCLUSIONS: Individuals with chronic health conditions and disabilities experienced service disruptions, even in a sample with considerably more economic, social, and educational privilege than the general population of people with chronic health conditions and disabilities in the United States.

Adoption of patient-reported outcome measures with youth with intellectual/developmental disabilities: Contextual influences and practice patterns.

BACKGROUND: The purpose of this study was to identify potential barriers to patient reported outcome measure (PROM) adoption with youth and young adults with intellectual and/or developmental disabilities (IDD) and to understand current PROM adoption patterns of paediatric practitioners working with this population. METHODS: We used a web-based survey to collect data from paediatric practitioners who work with youth with IDD about factors influencing the adoption of PROMs and the frequency of PROM use across age groups (elementary, middle school and high school/transition age) and practice settings (school and rehabilitation). RESULTS: A total of 113 paediatric practitioners (occupational therapist = 48, physical therapist = 32, physician = 16, other = 17) responded to the survey with an average of 15 years of experience working with youth ages 8-21 with IDD. Accessibility and appropriateness, psychometric evidence, and time were most frequently ranked among the top three factors that influence practitioners' adoption of PROMs. Practitioners reported 'never or rarely' using PROMs 39%-65% of the time across age groups. CONCLUSIONS: Our results suggest that paediatric practitioners may be infrequently using PROMs with youth with IDD because of perceived inaccessibility and time requirements of PROMs and practice-environment barriers, including access to evidence and caseload demands. Because PROMs can facilitate client-centred care, addressing these potential barriers to adoption may improve paediatric rehabilitation.

Deciphering the "Art" in Modeling and Simulation of the Knee Joint: Variations in Model Development.

The use of computational modeling to investigate knee joint biomechanics has increased exponentially over the last few decades. Developing computational models is a creative process where decisions have to be made, subject to the modelers' knowledge and previous experiences, resulting in the "art" of modeling. The long-term goal of the KneeHub project is to understand the influence of subjective decisions on the final outcomes and the reproducibility of computational knee joint models. In this paper, we report on the model development phase of this project, investigating model development decisions and deviations from initial modeling plans. Five teams developed computational knee joint models from the same dataset, and we compared each teams' initial uncalibrated models and their model development workflows. Variations in the software tools and modeling approaches were found, resulting in differences such as the representation of the anatomical knee joint structures in the model. The teams consistently defined the boundary conditions and used the same anatomical coordinate system convention. However, deviations in the anatomical landmarks used to define the coordinate systems were present, resulting in a large spread in the kinematic outputs of the uncalibrated models. The reported differences and similarities in model development and simulation presented here illustrate the importance of the "art" of modeling and how subjective decision-making can lead to variation in model outputs. All teams deviated from their initial modeling plans, indicating that model development is a flexible process and difficult to plan in advance, even for experienced teams.

Usability and Reliability of an Accessible Patient-Reported Outcome Measure (PROM) Software: The Pediatric Evaluation of Disability Inventory-Patient-Reported Outcome (PEDI-PRO).

IMPORTANCE: Patient-reported outcome measures (PROMs) are used in rehabilitation to evaluate outcomes. We integrated a new PROM for transition-age youth with intellectual and/or developmental disabilities (IDD), the Pediatric Evaluation of Disability Inventory-Patient-Reported Outcome (PEDI-PRO), with a computer-delivered survey platform (Accessible Testing Learning and Assessment System) to enhance cognitive accessibility. OBJECTIVE: To evaluate the usability of the PEDI-PRO software and to investigate its reliability and acceptability to transition-age youth with IDD. DESIGN: Clinical field testing and a survey; repeated-observation test-retest design. SETTING: Clinicians evaluated the PEDI-PRO's usability in school and health care contexts; research staff conducted reliability and acceptability testing in natural settings. PARTICIPANTS: Occupational therapists (n = 12) and physical therapists (n = 2) administered the PEDI-PRO to 39 youths with IDD. Fifty-five transition-age youth with IDD (M age = 19.7) completed the PEDI-PRO twice. OUTCOMES AND MEASURES: Clinicians completed the System Usability Survey (SUS) and open-ended feedback. Youth provided feedback via a brief survey. RESULTS: The mean SUS rating was 84.00 (SD = 11.68), exceeding the industry standard. Intraclass correlations ranged from .80 to .83 across the three PEDI-PRO domains. Internal reliability (α) was .86-.90 across domains. Youth reported that they liked the accessibility features: interface images, button sounds, read-aloud audio, and rating category choices (M = 88.8%, SD = 5.1%). CONCLUSIONS AND RELEVANCE: The PEDI-PRO supported transition-age youth with IDD to reliably report perceived functional performance. The accessible software was favorably perceived by both clinicians and youth. WHAT THIS ARTICLE ADDS: Design features of the PEDI-PRO make it easy to use in practice with transition-age youth with IDD. The PEDI-PRO's cognitively accessible administrative design, including step-by-step instructions for teaching PROM use and a self-reflective questioning technique, could serve as a training model for this and other PROMs.

Neutrophil to lymphocyte ratio and risk of neoplastic progression in patients with Barrett's esophagus.

BACKGROUND: Patient's with Barrett's esophagus (BE) are at risk of progression to esophageal adenocarcinoma (EAC). Neutrophil to lymphocyte ratio (NLR) was found to be a predictor of poor prognosis in patients with EAC; however, its performance in premalignant esophageal lesions is vague. We aimed to evaluate the utility of NLR as a predictor of histologic progression in patients with BE. METHODS : A prospective cohort of patients with proven BE in a tertiary referral center was retrospectively analyzed. All biopsies were reviewed by an expert gastrointestinal pathologist. The discriminatory capacity of NLR was evaluated by area under the receiver operating characteristic (AUC) curve analysis and Cox regression analysis. RESULTS: 324 patients (mean age 62.3 years, 241 [74.4 %] males) were included in the final analysis. Overall, 13 patients demonstrated histologic progression to neoplasia over a mean follow-up of 3.7 years (progression risk 1.0 % per year). The AUC of NLR for progression to high grade dysplasia (HGD) or EAC was 0.88 (95 % confidence interval [CI] 0.83 - 0.96), and baseline NLR was associated with a 3-fold increase of progression to HGD and EAC during follow-up (hazard ratio [HR] 3.2, 95 %CI 1.5 - 5.8; P < 0.001). Notably, in a subgroup analysis of patients with nondysplastic BE (NDBE) at presentation, NLR was also a risk factor for histologic progression (HR 2.4, 95 %CI 1.7 - 3.4; P < 0.001). CONCLUSION: NLR predicted histologic progression in patients with BE. Patients with NDBE and NLR above 2.4 can be considered for specific surveillance programs with shorter intervals between sessions.
