ABSTRACT Background Chronic obstructive pulmonary disease (COPD) is associated with musculoskeletal comorbidities, including cachexia. Weight loss (WL) is the major criterion for cachexia and increases risk for mortality in COPD. Risk factors for WL in COPD are incompletely understood. We performed this whole genome sequencing (WGS) analysis to identify genetic risk variants for WL in COPD. Methods We studied 16 972 participants from the Trans‐Omics for Precision Medicine (TOPMed) Initiative and All of Us Research Program. COPD was diagnosed using spirometry in TOPMed, while diagnosis codes were used in All of Us. WL was defined as WL ≥ 5% or a final body mass index (BMI) < 20 kg/m 2 . WGS data came from white blood cells in all cohorts. Single‐variant testing was conducted on both race‐ and study‐stratified cohorts and in a cosmopolitan, ancestry‐independent manner using GENESIS in TOPMed and SAIGE in All of Us. SAIGE‐GENE+ gene‐based analyses were performed on race‐stratified and cosmopolitan cohorts. Single variant meta‐analyses were conducted using METAL within (B/AA and NHW analyses of Black/African–American and non‐Hispanic white participants, respectively) and across racial groups (COSMO). Rare variant gene‐based results were combined using Fisher's method. Transcriptomic effects were predicted using MetaXcan. We used the GWAS Catalogue to analyse for colocalization with other related traits. Results Two single variants were associated with WL in COPD among All of Us participants: one intronic variant in HCN1 in Black/African–American participants (chr5:45271359:TACACAC:T, odds ratio with 95% confidence interval (OR (CI 95 )) = 2.43(1.78–3.31), p = 1.95 × 10 −8 ) and one intergenic variant between PPP4R2 and PDZRN3 in the cosmopolitan and NHW cohorts (chr3:73345901:A:G, OR (CI 95 ) = 0.21(0.12–0.35), p = 8.84 × 10 −9 in cosmopolitan and OR (CI 95 ) = 0.18(0.10–0.33), p = 9.44 × 10 −9 in NHW). Single‐variant meta‐analysis identified two loci associated with WL in COPD: five variants within DRAIC in the B/AA meta‐analysis (lead variant chr15:69571341:A:G, OR (CI 95 ) = 1.37(1.23–1.51), p = 1.29 × 10 −9 ) and two intronic variants within RFX3 in the cosmopolitan meta‐analysis (lead variant chr9:3390983:T:C, OR (CI 95 ) = 1.50(1.31–1.73), p = 1.06 × 10 −8 ). Rare variants within RNU6‐565P (NHW analysis in All of Us; p = 2.83 × 10 −7 ) and LOC339298 (B/AA analysis in All of Us, p = 1.85 × 10 −6 ) were associated with WL in COPD. The RNU‐565P signal remained significant after combination with TOPMed results (p combined = 1.23 × 10 −6 ). MetaXcan predicted differential expression of LNC00959 in visceral adipose tissue ( p = 1.16 × 10 −6 in COSMO analysis). Colocalization analyses identified genomic associations between BMI and variants in or near DRAIC , RFX3 , PDZRN3 , and LINC00959 . Conclusions In the first WGS analysis of WL in COPD, we have identified seven novel loci. Further characterization of these loci will validate our findings and improve our understanding of the molecular pathophysiology of this condition.

Background: Understanding drivers of supply and labor cost variation in orthopaedic surgery is crucial to provide value-based care. Time-driven activity-based costing (TDABC) is a more accurate methodology for capturing costs of care than traditional methods. Anterior cruciate ligament reconstruction (ACLR) is one of the most performed outpatient procedures within orthopaedic surgery. The purpose of this study was to characterize the cost composition of ACLR and identify factors that drive cost variation. Methods: Cost data for supplies and time-based personnel usage were extracted from electronic health records and were used to calculate costs using TDABC. TDABC methodology was applied to calculate the cost of personnel usage by multiplying the duration and associated cost per minute. Descriptive statistics and mixed-effects modeling were used to determine cost drivers. Results: This study included 861 patients who underwent ACLR at 8 hospitals. The mean patient age (and standard deviation) was 31.1 ± 11.6 years. Of the 861 patients, 350 were male and 511 were female; 85.6% of patients were White, 8.1% were Asian, and 3.4% were Black. There was 3.2-fold variation in supply costs ($2,950) and 1.6-fold variation in labor costs ($940) between the 10th and 90th percentiles. Overall, supply costs accounted for 58.2% of total costs, whereas labor costs comprised the remaining 41.8%. The intraoperative phase was the greatest generator of total cost (89.7%). After adjusting for surgeon and hospital variability, variation in total cost was most effectively explained by graft type, primary surgery status, and meniscal repair (conditional R 2 = 0.84; marginal R 2 = 0.27). On subanalysis, patients undergoing allograft ACLR had significantly higher total costs, implant costs, and age compared with those undergoing ACLR with any autograft type (all p < 0.01). Conclusions: The most notable drivers of labor and supply cost variation were graft type, surgeon, surgery center, primary surgery status, and concomitant meniscal repair. Understanding modifiable cost drivers may aid health systems in designing value-based pathways, implant formularies, and surgeon education programs. Future studies may integrate cost with outcome measures for a more holistic view of value. Level of Evidence: Economic and Decision Analysis Level III .

Abstract Purpose: Neurocognitive and endocrine dysfunction are potential complications of cranial irradiation. However, risk factors are poorly understood, impeding accurate prognostication and exploration of potential preventive interventions. The objective of this study was to evaluate the prognostic value of various vascular and genotypic risk factors for the development of radiation-related toxicities. Methods: This single-institution retrospective cohort study included patients with metastatic and malignant primary brain tumors who received cranial irradiation as part of their initial tumor-directed therapy. Demographic and treatment characteristics were collected, as well as putative vascular and genotypic risk factors. Univariate, multivariate, and machine-learning analyses were performed using five pre-specified measures of radiation-related toxicity. The primary outcome was change in mini-mental status exam (MMSE). Results: Eighty patients (53% male, mean age 55.7, 53% primary and 44% metastatic brain tumors) were included. Elevated homocysteine and ApOE4genotype were the strongest predictors of MMSE decline in the multivariate model (OR 3.96 [6.5-200, p<0.001 and 2.85 [1.92-27.6], p=0.004). Elevated homocysteine was associated white matter change on MRI and both physician and patient assessment. ApoE4allele was associated with new endocrine deficiency, and physician assessment. An online nomogram provides risk predictions for each of the five late toxicity outcomes: (https://afranklin22.shinyapps.io/PRMMSERadiationRiskFactors/) Conclusion: Two pre-treatment laboratory values (elevated homocysteine and ApOE genotype) were strongly associated with post-radiation neurocognitive and endocrine dysfunction using a variety of simple but clinically meaningful definitions of dysfunction. Our predictive algorithm can aid clinicians in stratifying baseline risk and should be validated in prospective trials.

ABSTRACT Background Metabolic dysfunction‐associated steatotic liver disease (MASLD) exhibits marked heterogeneity in fibrosis progression and liver‐related outcomes. Liver biopsy is not feasible for longitudinal risk stratification at scale, creating a need for validated non‐invasive biomarkers, particularly imaging biomarkers, that can predict clinically meaningful disease progression and liver‐related outcomes. Aims To describe the design and rationale of the GOLDMINE study, established to determine whether non‐invasive imaging biomarkers predict MASLD progression and liver‐related clinical outcomes. Methods GOLDMINE is an investigator‐initiated, multi‐centre, international longitudinal cohort enrolling up to 1000 adults with either biopsy‐proven MASLD or MASLD cirrhosis across the full fibrosis spectrum. Participants are recruited from 15 sites in the US and 4 international sites (Japan, Singapore and France). At baseline, participants undergo clinical phenotyping, vibration‐controlled transient elastography, and advanced magnetic resonance imaging (MRI), including proton‐density‐fat‐fraction and magnetic resonance elastography (MRE). MRI (and biospecimen banking) is repeated at 2‐year intervals (years 2 and 4), with annual follow‐up visits for up to 10 years. Baseline liver histology is centrally processed, digitized and reviewed by a single expert hepatopathologist; all MRI/MREs are centrally interpreted. Results The prespecified clinical outcomes include progression to cirrhosis, clinically significant portal hypertension, major adverse liver‐related outcomes (ascites, hepatic encephalopathy, portal hypertensive bleeding, liver transplantation/qualification), hepatocellular carcinoma, major adverse cardiovascular events, and all‐cause mortality, with independent central adjudication of all events. Conclusions GOLDMINE establishes a rigorously phenotyped MASLD cohort integrating centralized histology, advanced MRI‐based biomarkers, longitudinal biobanking, and adjudicated outcomes, providing a platform to validate imaging and blood‐based prognostic biomarkers in MASLD.

BACKGROUND AND OBJECTIVES: Perioperative protocols facilitate earlier discharge without compromising safety in nonfunctioning pituitary adenomas, but no large multicenter studies in the United States have investigated protocols regarding Cushing disease (CD). We sought to characterize perioperative protocols and how their implementation influences clinical outcomes in patients with CD. METHODS: A retrospective analysis was conducted using data from the Registry of Adenomas of the Pituitary and Related Disorders consortium comprising 13 US academic pituitary centers. Institutions were surveyed regarding perioperative procedures for patients undergoing transsphenoidal tumor resection for CD. The impacts of institutional procedures and approaches to implementation on length of stay (LOS) and unplanned 90-day readmission were evaluated. RESULTS: Thirteen institutions contributed survey responses and clinical data for a total of 832 patients meeting inclusion criteria. Ten (76.9%) institutions reported having a postoperative protocol, 9 (69.2%) used a formal document to outline their protocol, and 3 (23.1%) had protocols implemented into hospital policy. Mean LOS was significantly reduced in centers with an established protocol (3.14 vs 3.42 days, P = .032), and more so with a formal document (3.10 vs 3.48 days, P = .001) or hospital policy (2.72 vs 3.36 days, P < .001). Patients treated after protocol implementation experienced shorter LOS ( P < .001). Other factors associated with reduced LOS were presence of a separate CD pathway, intraoperative checklist specific to pituitary surgery, non-narcotic pain regimen, Foley removal order, dedicated outpatient advanced practice provider follow-up, and target discharge date ≤2 days. Intraoperative checklist ( P = .045), non-narcotic pain regimen ( P = .048), nasal packing ( P = .005), and 1-day target discharge date ( P = .032) were important factors against readmission. Compared with microscopic surgery, endoscopic surgery was associated with shorter LOS but increased readmission odds. CONCLUSION: This is the first multicenter study to illustrate that implementation of perioperative protocols is associated with a reduction in LOS and readmission risk in patients with CD.

Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included. PtGA and PhGA (0–10 scale), clinical evaluations, and patient‐reported outcomes (PROs) were collected every six months. Multivariable mixed‐effects linear regression identified factors associated with PtGA and PhGA using (1) clinical variables and (2) clinical variables plus PROs. Relative weight analysis (RWA) determined the relative importance of each variable. Discordance (≥2 points between PtGA and PhGA) was assessed using multinomial mixed‐effects logistic regression. Results Among 956 patients (83% women, 33% limited disease), mean PtGA and PhGA at enrollment were 4.2 (SD 2.6) and 3.4 (SD 2.0), respectively ( P < 0.001). RWA of clinical variables identified modified Rodnan skin score (mRSS) and New York Heart Association (NYHA) functional class as most influential for both global assessments. After including PROs, PtGA was most influenced by measures of pain, skin symptoms, and physical function. Discordance occurred in 53% of patients (35% PtGA worse, 18% PhGA worse). Worse PtGA was associated with higher overall pain and discomfort. Worse PhGA was associated with higher mRSS, worse NYHA class, higher pain interference, and lower diffusing capacity of the lung. Conclusion Discordance between PtGA and PhGA occurs commonly, highlighting the need for comprehensive symptom management and measurement of disease burden in this complex disease. In SSc, differences in PtGA and PhGA reflect dissimilar weighting of data elements.

Abstract Oncology Advanced Practice Providers (APPs), including Advanced Practice Registered Nurses, Physician Assistants, and Clinical Pharmacists (CPs), play a vital role in delivering high-quality, patient-centered cancer care across the United States. Despite their widespread presence in oncology practices, APPs remain underutilized in cancer clinical research, representing a missed opportunity to expand trial access and improve patient outcomes. Clinical trials are essential to advancing oncology care, yet participation remains critically low among adult patients. Given Oncology APPs’ and CPs’ central role in cancer care delivery, their meaningful engagement in oncology clinical trial research is imperative as the standard of oncology care. This position article, with contributions from 5 professional societies, presents solutions and resources to barriers limiting APPs’ and CPs’ involvement in cancer clinical research, including gaps in education, role expectations, limited protected time, restrictive policies, insufficient financial support, and underrecognition of contributions. Integrating APPs and CPs more fully into the clinical research enterprise is essential to improving trial access, patient outcomes, closing equity gaps, and accelerating innovation in oncology care.

Background: The most critical exam components in patients seeking rhinoplasty have not been established. Objective: To identify concordance among experienced rhinoplasty surgeons regarding the most important exam features for various deformities. Methods: An online questionnaire was distributed to board-certified facial plastic and plastic surgeons experienced in rhinoplasty, with seven nasal deformity categories: dorsal hump, crooked nose, boxy tip, pinched tip, droopy tip, saddle nose, and nonallergic nasal obstruction. For each, respondents were asked to rank the three most important anatomic regions to examine from the following: nasal bones, midvault cartilage, skin, radix, facial profile, lip, tip, septum, internal nasal valve, nostrils, inferior and middle turbinates. For each ranked region, up to three important features were chosen. Normalized Attention Scores (NAS) were calculated to determine agreement amongst surgeons. Results: A total of 13 facial plastic and 8 plastic surgeons were invited to participate and completed the questionnaire. All cases had high agreement demonstrated by NAS, with the dorsal hump case exhibiting the greatest variability in responses. Conclusions: In this survey of 21 rhinoplasty surgeons, there was general agreement regarding the most relevant anatomical structures and features, which may provide a conceptual foundation for identifying key exam features for seven common complaints in patients seeking rhinoplasty.

Abstract Background: [212Pb]VMT-a-NET is a novel, next generation alpha therapy agent for advanced somatostatin receptor 2 positive (SSTR2+) neuroendocrine tumors (NETs). Here, we present safety and efficacy update from the dose-finding phase 1/2a clinical trial (NCT05636618). Methods: Adults with well-differentiated unresectable or metastatic NETs, who were peptide receptor radionuclide therapy-naïve, showed progressive disease after at least one prior line of systemic therapy and demonstrated SSTR2-expression on PET images were treated with up to four cycles of study therapy at the assigned dose level. Participants were followed for dose-limiting toxicity (DLT) observation up to 42 days after the first dose. Efficacy was evaluated by investigators according to RECIST criteria v1.1. Results: As of 10-Dec-2025 (data cut-off [DCO]) a total of 56 participants were enrolled into Cohorts 1, 2 and 3, and received at least 1 dose of [212Pb]VMT-a-NET (n=2 in Cohort 1, n=46 in Cohort 2, and n=8 in Cohort 3 at a dose level of 2.5 mCi, 5 mCi, and 6 mCi, respectively). For data analysis purposes, participants were categorized into two different groups: a safety group and an efficacy group. The safety group included all participants treated by the DCO (n=56), while the efficacy group included only the Cohort 1 participants (n=2) and the first half of participants treated in Cohort 2 (n=23). Among all participants treated with at least 1 dose of [212Pb]VMT-a-NET (n=56), no DLTs, no grade 5 adverse events (AEs), no treatment-related discontinuations, no serious renal complications, no dysphagia and no clinically significant treatment-related myelosuppression were observed. Median follow-up time for all patients treated was 40 weeks (range: 6-97). Among the 25 participants followed for efficacy (n=2 in Cohort 1 and n=23 in Cohort 2), 19 out of 25 were with no progression as of the DCO. Median follow-up time for participants included in the efficacy group was 49 weeks (range: 6-97). Investigator-assessed RECIST v1.1 objective responses were observed in 9 out of 23 participants (39%) enrolled in the first half of Cohort 2 (8 confirmed). The 2 patients enrolled in Cohort 1 at 2.5 mCi still have stable disease after 2 years of follow up. Updated safety outcomes for all participants along with updated efficacy findings for participants in Cohorts 1 and 2 with sufficient maturity will be presented during the congress. Conclusions: Treatment with [212Pb]VMT-α-NET continues to be well-tolerated among all patients treated (n=56), and to show promising efficacy at the dose levels of 2.5 mCi and 5 mCi. The study is ongoing with Cohort 3 (6 mCi) currently open for enrollment. Citation Format: Thorvardur R. Halfdanarson, Richard L. Wahl, Vineeth Sukrithan, Brandon R. Mancini, Seyed A.
