Purpose To use publicly available injured list (IL) data to 1) describe Major League Baseball injury trends from 2010 to 2024; 2) analyze injury types and body regions affected to report the highest impact injuries; and 3) report the financial implications of time lost due to injury over this 15‐year period. Methods IL data for every Major League Baseball player (pitchers and position players) from the 2010 to 2024 regular seasons were collected using publicly available sources, including player demographics, IL placements, body part injured, and length of each IL stay. Player salaries were compiled to determine the “financial loss” per injury. Results Across 15 seasons, 8078 players were placed on the IL, totaling 478,085 days. The mean IL placements/year was 634, and the annual number increased by an additional 27 injuries/year ( P < .001). Mean total IL days/season was 31,872, and this increased year‐over‐year ( P = .008). Shoulder injuries represented the most IL placements (n = 1555), followed by elbow (n = 1344) and upper leg (n = 769). Elbow injuries averaged the most days missed/IL placement (mean: 93, median: 74) and the greatest total days missed (129,610), followed by shoulder (95,189). Pitchers comprised 55% of IL placements and most commonly injured their shoulder or elbow. Infielders and outfielders accounted for 21% and 16% of IL placements, respectively. A total financial loss of $9,636,753,291 was accumulated over 15 seasons. Financial loss increased season‐to‐season (+$32,309,178/year, P = .002). Elbow injuries accounted for the highest financial loss at $1,932,048,168 ($1,379,049 lost/injury). In 2024, $2,220,432 was lost/elbow injury, $1,110,573/shoulder injury, $1,397,322/any injury, and $952,973,760 total for the season. Conclusions This study observed that the number of players, IL placements, days spent on the IL, and financial loss due to injury increased steadily each year. Pitchers were the most frequently injured players with shoulder and elbow injuries being most common. Over the 15‐season study period, there was a total financial loss of nearly $9.7 billion due to salary paid to injured players, with elbow injuries contributing the highest loss at just under $2 billion. Clinical Relevance Injury trends and financial data from Major League Baseball highlight the growing burden of shoulder and elbow injuries, particularly in pitchers. These findings underscore the need for orthopaedic surgeons to focus on prevention, early intervention, and optimized surgical management of high‐impact injuries to reduce long‐term morbidity and associated financial costs at the elite level.

ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents. Procedure We surveyed AYAs with cancer ( n = 75) and their parents ( n = 52) participating in the Texas KidsCanSeq study. Among AYA‐parent pairs, we compared preferred and actual treatment DM roles. We explored associations among DM roles, having pediatric‐to‐adult care transition discussions, and clinical and sociodemographic characteristics. We report AYAs’ and parents’ preferences for involvement in shared decision‐making (SDM) with oncologists about cancer treatment. Results AYAs’ DM role preferences varied: 44% preferred to equally share DM with parents, 31% preferred AYA‐led DM, and 25% preferred parent‐led DM. Parents who preferred parent‐led DM had younger AYAs than parents who preferred equally shared DM ( p = 0.011). For actual DM, 48% of AYAs reported DM was equally shared, 24% reported DM was AYA‐led, and 28% reported DM was parent‐led. Most AYAs had their preferred role (73%). AYAs’ actual role did not significantly differ from their own or their parents’ preferences (both p > 0.05). Approximately half of AYAs reported recent pediatric‐to‐adult care transition discussions. AYAs’ DM preferences and participation in transition discussions did not significantly differ along clinical or sociodemographic characteristics (all p > 0.05). AYAs and parents perceived high importance across all aspects of SDM with oncologists. Conclusion In this diverse study population, AYAs desired engagement in treatment DM and SDM. Although specific role preferences varied, opportunities existed to increase discussion around pediatric‐to‐adult care transition.

Objective: This post hoc analysis of the CHAMPION-NMOSD trial evaluated the safety and efficacy of ravulizumab in patients with aquaporin-4 antibody-positive (AQP4-Ab+) neuromyelitis optica spectrum disorder (NMOSD) previously exposed or naïve to rituximab (RTX). Methods: Patients received weight-based intravenous ravulizumab with a loading dose followed by maintenance dosing every 8 weeks. Patients were stratified by prior RTX exposure: no RTX exposure (RTX-naïve) vs RTX exposure > 3 months before initiating ravulizumab (RTX-exposed). Key outcomes included treatment-emergent adverse events (TEAEs), serious TEAEs (TESAEs), relapse rates, and vaccination timing from the last RTX dose. Results: Of the 58 patients enrolled, 89.7% were female, with a mean age of 47.4 years, and 21/58 (36.2%) were RTX-exposed. Relapses occurred in 12/21 (57.1%) RTX-exposed patients between their first RTX dose and study entry. The safety profile of ravulizumab was generally similar between RTX-exposed and RTX-naïve groups. Common TEAEs included COVID-19, headache, urinary tract infection, and upper respiratory tract infection. UTIs were more frequent in RTX-exposed individuals. One patient in each group experienced a meningococcal infection. No adjudicated on-trial relapses were reported while on ravulizumab. Conclusions: Following initiation of ravulizumab, RTX-exposed and RTX-naïve patients with AQP4-Ab+ NMOSD achieved sustained disease control and demonstrated a manageable safety profile. Clinical Trial Information: The CHAMPION-NMOSD Trial; ClinicalTrials.gov identifier: NCT04201262 (registered October 06, 2020).

Objective: To evaluate the associations between surgeon-patient sex concordance, long-term clinical outcomes and healthcare costs. Background Data: Emerging data suggest surgeon-patient sex concordance may improve short-term outcomes, especially for female patients, yet its long-term effects remain unknown. Methods: We conducted a population-based retrospective cohort study of adults undergoing common surgeries in Ontario, Canada (2007-2019). Patients were followed for 90 and 365 days. Surgeon-patient sex concordance was categorized into four dyads. Multivariate generalized estimating equations clustered by procedure type evaluated composite and individual (complications, readmission, mortality) clinical outcomes and healthcare costs. Results: A total of 1,165,711 patients were included. Female patients treated by male surgeons, compared with female surgeons, were more likely to experience an adverse composite event (90 d: aOR 1.12, 95% CI 1.08–1.17, P <0.001; 365 d: aOR 1.09, 95% CI 1.05–1.14, P <0.001), with no association among male patients (90 d: aOR 1.00, 95% CI 0.94–1.05, P =0.89; 365 d: 0.99, 95% CI 0.92–1.07, P =0.87). Long-term total healthcare costs were greater for patients treated by male surgeons - an effect seen in both male patients (90 d: aRR 1.08, 95% CI 1.03-1.14, P =0.002 and 365 d: aRR 1.08, 95% CI 1.02-1.14, P =0.007) and female patients (90 d: aRR 1.10, 95% CI 1.05-1.14, P <0.001, 365 d: aRR 1.09, 95% CI 1.05-1.14, P <0.001). Conclusions: Surgeon-patient sex concordance was associated with improved long-term outcomes for female, but not male, patients, and female surgeons’ patients had lower healthcare costs. Given these benefits, further investigation into the mechanisms driving these outcomes is warranted.

ABSTRACT Imaging mass spectrometry has made significant advancements in recent years owing to its ability to study the spatial localization and abundance of proteins, peptides, lipids, glycans, metabolites, and drugs. In this study, we employed an imaging mass spectrometry‐based workflow called MALDI‐IHC, which uses antibodies conjugated with photocleavable mass‐tags, to investigate the detection of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) along with pan‐cytokeratin in formalin‐fixed paraffin‐embedded (FFPE) sections from cases with breast cancer. The expression of ER, PR, and HER2 was consistent with the clinical diagnosis based on conventional immunohistochemistry, lacking signal in triple‐negative cases and concordant signals in the cases that were classified as ER+/PR+/HER2+, ER+/PR+/HER2−, and ER−/PR−/HER2+ groups, respectively. In addition, the potential utility of a seconday antibody‐based MALDI‐IHC approach for HER2 expression was evaluated. In agreement with immunohistochemistry results, HER2 expression co‐localized within tumor regions in a HER2+ breast cancer case, while no expression was observed in a HER2− case. Collectively, these results highlight the potential of imaging mass spectrometry‐based MALDI‐IHC workflow for multiplexed detection of proteins in clinically relevant tissue sections.

Abstract Current assessments of brain permeability rely predominantly on drug delivery to contrast-enhancing tumor regions. However, substantial portions of central nervous system (CNS) tumors reside within non-enhancing brain (NEB), where drug concentrations frequently remain subtherapeutic. This collaborative Adult Brain Tumor Consortium and Food and Drug Administration workshop aimed to identify criteria for defining NEB permeability to accomplish 2 critical objectives: (1) allocate clinical trial resources toward agents achieving therapeutic NEB concentrations and (2) minimize systemic toxicity when CNS benefit is improbable. The workshop systematically evaluated permeability assessment modalities, including drug physicochemical properties, in vitro blood-brain barrier models, and penetration into cerebrospinal fluid and normal rodent brain. Methodological approaches to determine requisite NEB drug concentrations and approaches to measuring NEB pharmacokinetics and pharmacodynamics were examined. This culminated in developing the Non-Enhancing Brain Permeability Index (NEBPI), which assigns therapeutic agents to 3 categories: sufficiently permeable, insufficiently permeable, or impermeable. The NEBPI provides a standardized framework to assist investigators and regulatory agencies to evaluate NEB penetration before human efficacy studies are initiated for agents that require direct tumor contact. Assessing NEB drug penetration is critical to improving outcomes in CNS tumors and reducing the incidence of brain metastases in systemic malignancies.

Abstract Rare Mendelian disorders affect 300-400 million people globally. Although genetic testing has become widely adopted, gene-specific evidence for tailored variant interpretation remains scattered across resources. We present Gene Portals, a framework for gene-centered multimodal knowledge bases that co-localize expert-harmonized clinical data, functional assays, population variation, structural annotations and gene-specific ACMG/AMP specifications within a single resource. A modular interface integrates this unified evidence with VCEP-refined ACMG specifications to enable automated gene-specific variant classification, infer molecular mechanisms, and support cross-gene analyses. We demonstrate the framework’s utility across five Gene portals spanning eleven neurodevelopmental disorder-associated genes, integrating data from 4,423 individuals with 2,838 unique variants, 36,149 ClinVar submissions, and 1,044 expert-curated molecular readouts. By organizing evidence that is otherwise dispersed across multiple sources into a unified, queryable framework, the SCN, GRIN, CACNA1A, SATB2 and SLC6A1 Gene Portals became widely used community resources and provide an extensible template for standardized rare-disease variant interpretation and mechanism-aware discovery.

755 Background: Patients with High-Risk BCG-Unresponsive Non-Muscle Invasive Bladder Cancer have limited treatment options. The US FDA approved treatments for BCG-UR patients with CIS, but additional bladder-sparing therapies are needed, especially for the BCG-UR papillary-only population. Cretostimogene is an oncolytic immunotherapy with dual mechanisms of action. It replicates in and lyses cancer cells with Rb-E2F pathway alterations. This releases tumor-specific antigens, initiating an anti-tumor immune response, further amplified by the GM-CSF transgene. The BOND-003 Cohort P study (NCT04452591) is a single-arm clinical trial assessing the efficacy and safety of intravesical cretostimogene in HR, papillary-only, BCG-UR NMIBC patients. Methods: Eligibility criteria include age ≥18 years, ECOG PS of 0-2, and histologically confirmed BCG-UR HG Ta/T1 papillary disease without CIS within 90 days of study enrollment as verified per central pathology review. Patients had no visible evidence of residual bladder cancer before treatment. Intravesical cretostimogene is instilled for six weekly doses during the induction phase, followed by three weekly maintenance cycles quarterly through Month 12, then every six months through Month 36. Re-induction is permitted at 3 months for patients with HG Ta or CIS. Primary disease assessments include serial cystoscopy, urine cytology, axial imaging, and mandatory biopsy directed at prior tumor locations at Month 12, with centralized review of pathologic samples. Endpoints include HG-RFS, HG-EFS, PFS, and safety. The study has completed enrollment. Results: A total of 56 patients who received treatment with cretostimogene are evaluated based on data from September 1, 2025 cut off. At baseline, 76.7% of patients are 65 years or older, 21.4% are female, 64.3% have HG Ta, and 35.7% have HG T1 papillary NMIBC. Kaplan-Meier estimates of HG-RFS at 6- and 9-months are 84.6% (95% CI 73.1 - 96.1%) and 80.4% (95% CI 66.8-94.0%), respectively. No patients have undergone a radical cystectomy. One patient progressed to metastatic disease despite a clinical complete response in the bladder. Cretostimogene demonstrates a favorable safety profile, with most adverse events localized to low grade bladder symptoms. There are no serious treatment-related adverse events and no discontinuations related to cretostimogene. To date, no patients have required a dose delay or missed a dose due to a related adverse event. There have been no deaths related to study treatment. Further, updated data will be presented. Conclusions: These results demonstrate consistent efficacy and a well-tolerated safety profile. Mature data with longer term follow-up will build upon these promising findings and will inform future treatment approaches with cretostimogene. Clinical trial information: NCT04452591 .

Abstract Introduction Combat casualty care requires standardized proficiency criteria to ensure readiness in austere environments, yet gaps persist in defining performance thresholds for critical trauma skills. The Combat Medical Skills Sustainment Consortium (CMSSC), a novel military-civilian collaboration, aimed to validate competency thresholds for 21 Department of Defense-identified trauma skills. Materials and Methods A prospective cohort study (2022-2025) enrolled 1,495 military and civilian personnel across five academic centers, stratified by experience (novice, intermediate, expert). Skills, including cricothyroidotomy, whole blood transfusion, and ultrasound-guided vascular access, were assessed using validated checklists in Role 2-congruent simulations. Statistical analysis compared checklist performance against participant experience with a priori checklist scores estimated at 40% (novices) and 90% (experts). Results Competency thresholds were established, ranging from 77% (mechanical ventilation) to 100% (handoff). Experts achieved 85%-98% proficiency across most skills, with novices at 34%-97%. A ceiling effect was observed for less complex skills consistent with the power law of practice. Conclusion The Combat Medical Skills Sustainment Consortium validated standardized assessment tools, with potential to address readiness gaps through military-civilian synergy. Findings support consortium-guided curriculum development and highlight the need for longitudinal skill decay studies. Impact This study sets a benchmark for trauma care skills assessment, facilitating rapid adoption across military and civilian settings.

ABSTRACT Meningiomas are the most common primary brain tumors and, despite their benign reputation, often behave aggressively. Meningiomas are morphologically heterogeneous, yet the full significance of their histologic diversity is unclear. This is in large part because many features are not readily quantifiable by traditional observer-based light microscopy. Molecular testing improves prognostic stratification, but is not universally accessible. We therefore sought to determine whether an artificial intelligence (AI)-trained program could predict specific genomic and epigenomic patterns in meningiomas, and whether it could extract more prognostic information out of standard hematoxylin and eosin (H&E) histopathology than the current WHO classification. To do this, we developed Morphologic Set Enrichment (MSE), an interpretable computational pathology framework that quantifies statistical enrichment of morphologic patterns, cells, and tissue architecture from H&E whole-slide images. The MSE meningioma histology program was able to accurately predict DNA methylation subtypes and concurrent chromosome 1p/22q losses, in the process identifying specific morphologic patterns associated with key genomic and epigenomic alterations. It also added prognostic value independent of standard clinical and pathological variables. These results demonstrate that AI-based quantitative morphologic profiling can capture clinically and biologically relevant information that redefines risk stratification for meningiomas, incorporating histological information not included in existing grading schemes.
