Background: Currently, biomarkers do not have a role in diagnosis or outcome prediction models for patients with recurrent anterior shoulder instability. Purpose/Hypothesis: The purpose of this study was to compare gene expression differences in the blood and tissue of patients with anterior shoulder instability with and without significant glenoid bone loss (GBL). The hypothesis was that the severity of GBL would be associated with the expression level of genes in the blood and capsular tissue of patients with anterior shoulder instability. Study Design: Descriptive laboratory study. Methods: Consecutive patients with anterior shoulder instability undergoing arthroscopic and open shoulder stabilization were prospectively enrolled. Blood and anterior capsular tissue specimens obtained during surgery were compared between patients with significant GBL (≥10%) and patients without significant GBL (<10%). RNA was extracted, and a panel of 277 inflammatory genes was utilized to quantify gene expression at the RNA level using a probe-based RNA quantification platform. Differential expression analysis was performed to identify genes expressed at different levels between patients with and without significant GBL. The expression levels of the subset of genes identified were used to generate a ridge regression model to predict the severity of GBL. Quantitative polymerase chain reaction was performed to confirm probe-based RNA findings. Results: A total of 17 patients were included, with a mean age of 26 years. Overall, 7 patients had <10% GBL (mean, 2.3%), and 10 patients had ≥10% GBL (mean, 16.4%). There were 9 genes that were identified as significantly differentially expressed in the blood, and 5 of these ( IFIT1 , IFIT3 , IFI44 , PRKCB , and OAS2 with P values of 1 × 10 −5 , 1 × 10 −4 , 1 × 10 −4 , 1 × 10 −4 , and 6 × 10 −4 , respectively) were confirmed using nonparametric tests. The authors developed a model using the 5 genes to predict the severity of GBL, and this had an accuracy of 88% (95% CI, 64%-99%). By quantitative polymerase chain reaction, IFIT3 was confirmed to be significantly differentially expressed ( P = .012). Conclusion: There were significant gene expression differences in the blood of patients with (≥10%) and without (<10%) significant GBL. The differential expression of 5 genes allowed for the development of an accurate predictive model and transcriptomic biomarker to predict the severity of GBL. Clinical Relevance: The addition of a blood biomarker to current outcome prediction models may provide increased accuracy in identifying those at risk of failure from arthroscopic Bankart repair.

Objectives: Many individuals with dementia with Lewy bodies (DLB) die of disease-related complications, but predicting the end of life can be challenging. We identified a phenotype associated with approaching end of life. Methods: We present 4 exemplar cases where individuals with DLB experienced refractory psychosis before death. We reviewed codebooks and quotes from 3 studies regarding end-of-life experiences in DLB to identify experiences that aligned with this phenotype. Results: In addition to the 4 cases, family caregivers in prior studies described prominent worsening of psychosis before death in some individuals with DLB. The worsening often occurred several months before death and was sometimes associated with rapid deterioration. Worsening psychosis was the prominent symptom and was not initially accompanied by cognitive or physical decline. In many cases, the refractory psychosis resulted in inpatient psychiatric hospitalization or residential care, but these scenarios were challenging because of the individual’s behavior. Conclusion: Refractory psychosis in DLB, particularly out of proportion to other symptoms, may be a signal of approaching the end of life. More research is needed to understand this phenomenon and to develop effective and safe treatments for psychosis in DLB.

AbstractINTRODUCTIONLittle is known regarding quality of life (QoL) in dementia with Lewy bodies (DLB), particularly in advanced stages.METHODSDyads of individuals with moderate–advanced DLB and their primary caregivers were recruited from specialty clinics, advocacy organizations, and research registries. The study collected demographics, disease‐related measures, and measures of patient/caregiver experiences.RESULTSThe Quality of Life in Alzheimer's Disease (QoL‐AD) was completed by the person with DLB and the caregiver (proxy) in 61 dyads; 85 dyads had only a proxy‐completed QoL‐AD. Patient‐ and proxy‐reported scores were moderately correlated (r = 0.57, P < 0.0001). Worse patient‐reported QoL correlated with daytime sleepiness, autonomic symptom burden, and behavioral symptoms. Proxy ratings correlated with dementia severity, daytime sleepiness, behavioral symptoms, dependence in activities of daily living, and caregiver experience measures.DISCUSSIONPatient‐ and proxy‐reported quality of life (QoL) should be assessed separately in advanced DLB. Some symptoms associated with QoL have available therapeutic options. Research is needed regarding strategies to optimally improve QoL in DLB.Highlights Patient and proxy quality of life (QoL) ratings had moderate correlation in advanced dementia with Lewy bodies. Daytime sleepiness affected patient‐ and proxy‐reported QoL. Behavioral symptoms affected patient‐ and proxy‐reported QoL. Autonomic symptom burden affected patient‐reported QoL. Dementia severity, dependence, and caregiver experiences affected proxy ratings.

AbstractDespite its high prevalence among dementias, Lewy body dementia (LBD) remains poorly understood with a limited, albeit growing, evidence base. The public‐health burden that LBD imposes is worsened by overlapping pathologies, which contribute to misdiagnosis, and lack of treatments. For this report, we gathered and analyzed public‐domain information on advocacy, funding, research outputs, and the therapeutic pipeline to identify gaps in each of these key elements. To further understand the current gaps, we also conducted interviews with leading experts in regulatory/governmental agencies, LBD advocacy, academic research, and biopharmaceutical research, as well as with funding sources. We identified wide gaps across the entire landscape, the most critical being in research. Many of the experts participated in a workshop to discuss the prioritization of research areas with a view to accelerating therapeutic development and improving patient care. This white paper outlines the opportunities for bridging the major LBD gaps and creates the framework for collaboration in that endeavor.Highlights A group representing academia, government, industry, and consulting expertise was convened to discuss current progress in Dementia with Lewy Body care and research. Consideration of expert opinion,natural language processing of the literature as well as publicly available data bases, and Delphi inspired discussion led to a proposed consensus document of priorities for the field.

Background and Significance: Allogeneic hematopoietic cell transplantation (alloHCT) is a curative immunotherapy for patients with hematologic disorders. However, graft-versus-host-disease (GVHD) is a major limitation to the success of alloHCT, with chronic GVHD (cGVHD) as the leading cause of morbidity and mortality. The pleomorphic nature of cGVHD makes the diagnosis and patient management challenging for clinicians; thus, patient-reported symptoms often guide in diagnosing and determining the severity of cGVHD. Our current understanding of cGVHD is largely based on data from registries, single-institution prospective studies, and the cGVHD Consortium with representation from tertiary care academic centers. Prospective studies including patient-reported outcomes and a focus on a more representative and generalizable sample of patients with cGVHD are needed to better understand cGVHD symptoms, disease burden, and practice patterns for management. This trial in progress focuses on broad patient-centered assessment of post-alloHCT medical and psychosocial complications and patient-reported caregiver involvement in a diverse and contemporary patient population. This study uses multiple organ- or system-directed patient-reported outcome measures (PROMs) to help identify cGVHD symptoms, severity, and impact on patient quality of life including financial impact. The primary objective of THRIVE is to assess the clinical course and burden of cGVHD, including diagnosis and severity recorded in electronic case report forms (eCRFs) and PROMs. Secondary objectives include measuring healthcare resource utilization and patient economic and employment impact associated with cGVHD management, as well as patient-reported organ-specific symptoms. Study Design and Methods: THRIVE is a prospective, longitudinal, observational study (NCT05919511) of alloHCT recipients in the United States that uses a hybrid model designed to work with HCT centers and a virtual platform. Eligible patients are ≥18 years old, received alloHCT 90-180 days before enrollment, and are able to complete patient-assessment questionnaires provided in their preferred language either alone or with minimal caregiver assistance. Up to 1500 alloHCT recipients will be recruited at HCT sites (with the expectation that ~500 will have cGVHD symptoms at enrollment; ~500 are estimated to develop cGVHD during the course of the study; ~500 are estimated not to develop cGVHD during the study; Figure). Patients have the option to participate on a virtual platform. Patients will be followed for 36 months from date of enrollment or until the earliest of study termination, withdrawal, or death. Data from 13 PROMs (Table) divided into 3 groups will be collected every 3 months using a decentralized virtual platform. To reduce survey burden, patients will be randomized into 1 of 6 sequence groups to capture 4-5 PROMs per month in year 1 and every 2 months in years 2 and 3. Clinical data, including medications and adverse events, will be collected and abstracted into eCRFs every 3 months. In general, reporting of results will be descriptive for variables of interest. Summary statistics for continuous variables and for categorical variables will be calculated for all patients as well as for subgroups of interest. Whenever applicable, 95% confidence intervals will be calculated for endpoint estimates. Univariate, multivariate, or repeated-measurement analyses will be performed to assess factors associated with evolution of clinical manifestations of and complications from cGVHD. Recruitment for this study is ongoing.

Abstract Background Technological improvements and, subsequently, the federal 21st Century Cures Act have resulted in increased access to and interoperability of electronic protected health information (ePHI). These not only have many benefits, but also have created unique challenges for privacy and confidentiality for adolescent patients. The inability to granularly protect sensitive data and a lack of standards have resulted in limited confidentiality protection and inequitable access to health information. Objectives This study aimed to understand the challenges to safe, equitable access, and interoperability of ePHI for adolescents and to identify strategies that have been developed, ongoing needs, and work in progress. Methods Shift, a national task force formalized in 2020, is a group of more than 200 expert stakeholder members working to improve functionality to standardize efforts to granularly identify and protect sensitive ePHI to promote equitable interoperability. Results Shift has created high-priority clinical use cases and organized challenges into the areas of Standards and Terminology; Usability and Implementation; and Ethics, Legal, and Policy. Conclusion Current technical standards and value sets of terminology for sensitive data have been immature and inconsistent. Shift, a national diverse working group of stakeholders, is addressing challenges inherent in the protection of privacy and confidentiality for adolescent patients. The diversity of expertise and perspectives has been essential to identify and address these challenges.

Importance Lensectomy with primary intraocular lens (IOL) implantation is often used in the management of nontraumatic pediatric cataract, but long-term data evaluating the association of age and IOL location with the incidence of complications are limited. Objective To describe the incidence of complications and additional eye surgeries through 5 years following pediatric lensectomy with primary IOL implantation and association with age at surgery and IOL location. Design, Setting, and Participants This prospective cohort study used Pediatric Eye Disease Investigator Group cataract registry data from 61 institution- and community-based practices over 3 years (June 2012 to July 2015). Participants were children younger than 13 years without baseline glaucoma who had primary IOL implantation (345 bilateral and 264 unilateral) for nontraumatic cataract. Data analysis was performed between September 2021 and January 2023. Exposures Lensectomy with primary IOL implantation. Main Outcome and Measures Five-year cumulative incidence of complications by age at surgery (&amp;lt;2 years, 2 to &amp;lt;4 years, 4 to &amp;lt;7 years, and 7 to &amp;lt;13 years) and by IOL location (sulcus vs capsular bag) were estimated using Cox proportional hazards models. Results The cohort included 609 eyes from 491 children (mean [SD] age, 5.6 [3.3] years; 261 [53%] male and 230 [47%] female). Following cataract extraction with primary IOL implantation, a frequent complication was surgery for visual axis opacification (VAO) (cumulative incidence, 32%; 95% CI, 27%-36%). Cumulative incidence was lower with anterior vitrectomy at the time of IOL placement (12%; 95% CI, 8%-16%) vs without (58%; 95% CI, 50%-65%), and the risk of undergoing surgery for VAO was associated with not performing anterior vitrectomy (hazard ratio [HR], 6.19; 95% CI, 3.70-10.34; P &amp;lt; .001). After adjusting for anterior vitrectomy at lens surgery, there were no differences in incidence of surgery for VAO by age at surgery (&amp;lt;2 years, HR, 1.35 [95% CI, 0.63-2.87], 2 to &amp;lt;4 years, HR, 0.86 [95% CI, 0.44-1.68], 4 to &amp;lt;7 years, HR, 1.06 [95% CI, 0.72-1.56]; P = .74) or by capsular bag vs sulcus IOL fixation (HR, 1.22; 95% CI, 0.36-4.17; P = .75). Cumulative incidence of glaucoma plus glaucoma suspect by 5 years was 7% (95% CI, 4%-9%), which did not differ by age after controlling for IOL location and laterality. Conclusions and Relevance In this cohort study, a frequent complication following pediatric lensectomy with primary IOL was surgery for VAO, which was associated with primary anterior vitrectomy not being performed but was not associated with age at surgery or IOL location. The risk of glaucoma development across all ages at surgery suggests a need for long-term monitoring.
