Sharing research code in an open access version-controlled repository offers significant benefits for both science as a whole and for individual researchers. In this article, we focus on this practice, which is fully aligned with the NIH’s Gold Standard Science (GSS) program as well as FAIR (findable, accessible, interoperable, reusable) and TRUST (transparency, responsibility, user focus, sustainability, technology) principles. Gold Standard Science supports open science by emphasizing transparency, reproducibility, and the use of best practices that enable others to verify and extend research. Pairing a research article’s cited data snapshot with a versioned, environment-specific code release, deposited in a companion code repository, ensures that, upon submission to a medical journal, readers and reviewers can directly verify results. An executable and updatable companion code repository complements, rather than replaces, established research data repositories. When code underlying medical research results is made openly available, then other scientists can inspect, run, and validate analyses. These activities enhance reproducibility, which is a core aim of GSS. Shared code also facilitates collaborative innovation by allowing researchers to extend the utility of the code to new datasets and applications. For researchers, code sharing can increase visibility, credibility, and citation impact. Demonstrating transparency through shared executable and updatable code builds trust with journal readers, peer reviewers, funders, and peers. Shared code in an open access repository signals adherence to high standards of scientific integrity and attracts opportunities for collaboration. A researcher who shares code receives recognition as a leader in reproducible, trustworthy research consistent with NIH’s GSS principles.

Abstract: AIM: The purpose of this study is to investigate the safety and effectiveness of remote ischemic conditioning (RIC) as a therapeutic intervention for cerebral ischemia in patients with Takayasu arteritis (TA). METHODS: TARIC-1 is a randomized, double-blind, parallel-group pilot trial conducted at Xuanwu Hospital, Capital Medical University. Participants with TA and reduced cerebral blood perfusion are randomly allocated to either the RIC or sham-RIC groups. Both the groups receive conventional medical care, with the RIC group receiving twice-daily sessions of 200 mmHg inflation pressure and the sham-RIC group receiving 60 mmHg inflation pressure, for 24 consecutive weeks. OUTCOMES: The primary outcome is the change in mean cerebral blood flow across the entire brain and regions of interest following the 24-week RIC treatment. Secondary outcomes include clinical assessments using the Indian Takayasu Clinical Activity Score 2010, Vasculitis Damage Index, and Birmingham Vasculitis Activity Score at 24 weeks postintervention. Changes in arterial transit time and the incidence of major adverse cerebrovascular events are additional secondary outcomes. Safety outcomes include mortality and any adverse events, including skin changes and pain ratings, within the 24-week period. SAMPLE SIZE ESTIMATES: This pilot study plans to enroll 22 patients per group, totaling 44 participants. CONCLUSIONS: In individuals with TA, RIC may be a well-tolerated treatment that enhances cerebral perfusion and lowers the risk of ischemic cerebrovascular episodes.

TPS256 Background: Currently, there are no biomarkers validated prospectively in randomized studies for resected colon cancer (CC) to determine need for adjuvant chemotherapy (AC). However, circulating tumor DNA (ctDNA) represents a highly specific and sensitive approach (especially with serial monitoring) for identifying minimal/molecular residual disease (MRD) post-surgery in CC patients (pts), and may outperform traditional clinical and pathological features in prognosticating risk for recurrence. CC pts who do not have detectable ctDNA (ctDNA-) are at a much lower risk of recurrence and may be spared the toxicities associated with AC. Furthermore, for CC pts with detectable ctDNA (ctDNA+) who are at a very high risk of recurrence, the optimal AC regimen has not been established. We hypothesize that for pts whose CC has been resected, ctDNA status may be used to risk-stratify for making decisions about AC. Methods: In this prospective phase II/III trial, up to 1,912 pts with resected stage IIB, IIC, and III CC will be enrolled. Based on the post-operative ctDNA status using personalized and tumor-informed assay (Signatera, bespoke assay), those who are ctDNA- (Cohort A) will be randomized to immediate AC with fluoropyrimidine (FP)+oxaliplatin (Ox) for 3-6 mos per established guidelines v serial ctDNA monitoring. Patients who are ctDNA+ post-operatively, or with serial monitoring (Cohort B), will be randomized to FP+Ox v more intensive AC with addition of irinotecan (I) for 6 mos. One cycle of chemotherapy is allowed while awaiting ctDNA testing results for cohort assignment. The primary endpoints for Cohort A are time to ctDNA+ status (phase II) and disease-free survival (DFS) (phase III) in the immediate v delayed AC arms. The primary endpoint for Cohort B is DFS in the FP+Ox v FP+Ox+I arms for both phase II and phase III portions of the trial. Secondary endpoints include prevalence of detectable ctDNA post-operatively, time-to-event outcomes (overall survival and time to recurrence) by ctDNA status, and the assessment of compliance to adjuvant therapy. Biospecimens including archival tumor tissue, as well as post-operative plus serial matched/normal blood samples, will be collected for exploratory correlative research. Active enrollment across the NCTN started in June 2022 with CCTG sites joining in August 2023. Current accrual (as of 9-4-2025): 967/1,912. Drs. Lieu and Dasari contributed equally to the development of this trial. Clinical trial information: NCT05174169 .

707 Background: Due to insufficient data, therapy for unresectable, locally advanced pancreatic adenocarcinoma (LAPAC) is based on trials in metastatic disease, and outcomes remain poor. TTFields disrupt cancer cell division using alternating low-frequency electric fields delivered externally by a portable device. In the phase 3 PANOVA-3 trial (NCT03377491), TTFields with gemcitabine/nab-paclitaxel (GnP) significantly improved overall survival (OS; HR 0.82) and pain-free survival (HR 0.74) vs GnP in patients with unresectable LAPAC. Methods: In PANOVA-3, patients with newly diagnosed LAPAC were randomized 1:1 to receive GnP with or without concomitant TTFields. Kaplan-Meier methodology was used for time-to-event analyses. Response evaluations were based on RECIST V1.1. OS, pain-free survival, and safety were analyzed post-hoc in subgroups based on sex (male, female), age ( < 65, ≥65 years), and BMI (<25, ≥25 kg/m 2 for efficacy; ≤20, 20–25, 25–30, ≥30 kg/m 2 for safety). Differences between treatment arms were compared using the log-rank test. Results: Efficacy outcomes are shown in the table. TTFields significantly extended pain-free survival in females and patients ≥65 years. Device-related adverse events (AEs) were comparable between sexes, older and younger patients, and across BMI ranges. Some device-related skin adverse events occurred more frequently in females (e.g. dermatitis, 33.1% vs 22.7%; rash 21.8% vs 13.5%, females vs males, respectively); others occurred more often in males (e.g. maculo-papular rash, 9.8% vs 14.2%; erythema, 9% vs 12.1%, females vs males, respectively). Dermatitis and pruritus had a higher incidence in the BMI ≥30 kg/m 2 subgroup (38.5%), whereas patients with BMI <30 kg/m 2 did not show noticeable differences in device-related AEs. Skin irritation (11.5% vs 5.5%) and skin reactions (8.5% vs 2.8%) were more common in patients ≥65 years than patients <65 years. Conclusions: Median OS and pain-free survival in these post-hoc subgroup analyses are generally consistent with the overall analysis, supporting use of TTFields with GnP in unresectable LAPAC. No new safety concerns were noted; observations were consistent with the general PANOVA-3 population. Clinical trial information: NCT03377491 . Survival outcomes for the subgroup analyses.

163 Background: Being physically inactive is an independent predictor of poor outcomes in patients with stage III colon cancer. Whether physical activity can mitigate the oncologic risk of postoperative MRD is unknown. Methods: We concluded a post hoc analysis of a phase III trial evaluating celecoxib vs. placebo and 3 vs. 6 months of adjuvant chemotherapy in patients with resected stage III colon cancer. Self-reported physical activity was assessed in standardized measures of metabolic equivalent hours per week (MET-h/wk) at 2 timepoints: 1) midway through and 2) 6 months after completing adjuvant chemotherapy, modeled as a time-weighted average. MRD was determined via a clinically validated, tumor-informed circulating tumor DNA (ctDNA) assay (Signatera, Natera, Inc.). Disease-free survival (DFS) and overall survival (OS) were estimated using flexible parametric survival models. Results: Among 763 patients (median follow-up 6.0 years), 24% were highly active (≥18 MET-h/wk) and 32% were inactive (<3 MET-h/wk); 18% were ctDNA positive. Adjusting for covariates, DFS improved in patients who were ctDNA negative and moderately active (Ref: inactive; 3-17.9 MET-h/wk; HR=0.62, 95% CI [0.40-0.97]) or highly active (HR = 0.53 [0.30-0.94]). No benefit was seen among patients who were ctDNA positive (Ref: inactive; moderately active: HR = 1.20 [0.75-1.92]; highly active: HR=0.83 [0.45-1.54]). The interaction was not significant (Pint=0.269). Physical activity did not impact OS regardless of ctDNA status. The interaction of physical activity and adjuvant celecoxib use is shown in Table. Conclusions: Among patients who were ctDNA negative, physical activity was associated with improved DFS, and may demonstrate increased survival benefit alongside adjuvant celecoxib. The additive effects of both interventions were inconclusive among those who were ctDNA positive.

Abstract Background Fecal microbiota, live-jslm (RBL) is FDA-approved for prevention of recurrent Clostridioides difficile infection (rCDI) in adults following completion of antibiotic treatment. The safety and efficacy of RBL have been demonstrated in trials, but few studies have evaluated outcomes in real-world populations. The primary objective of ROAR (NCT05835219) is to assess RBL effectiveness in reducing rCDI through 8 weeks in clinical practice. Table 1. Treatment success rates by subgroup Methods ROAR is an ongoing, prospective, multicenter, open-label, non-interventional registry of patients receiving RBL for rCDI prevention in the United States. Adults who completed antibiotics for rCDI and are not in an interventional trial are eligible. The primary endpoint assesses the proportion of patients who experience treatment success (no CDI recurrence through 8 weeks). Other objectives describe rCDI management in real-world clinical practice and adverse events (AEs) after RBL administration. This analysis includes patients who received RBL within 30 days of completing antibiotics for rCDI. Results As of September 18, 2024, 76 patients received RBL within 30 days of completing antibiotics and completed 8 weeks of follow-up. Patients were mostly White (93.4%) and female (76.3%), with a median age of 69 years (range, 19-96 years) and a median body mass index of 24.4 (range, 16.5-49.4). Through 8 weeks, 82.9% of patients (63/76; 95% CI, 72.5%-90.6%) experienced treatment success. Similarly, the rate of treatment success was 87.8% (36/41) in the subgroup of patients who received RBL after an antibiotic washout period &gt; 72 hours. Treatment success rates ranged from 77-100% across patient subgroups, including those stratified by age and number of previous CDI episodes within the past 3 years (Table). Overall, 18 (23.7%) patients experienced an AE, 6 (7.9%) experienced a serious AE, and 1 (1.3%) experienced an AE of special interest (large bowel obstruction). AEs assessed as related to RBL occurred in 3 patients (3.9%). There was 1 fatal AE during the study, considered unrelated to RBL. Conclusion Initial results from ROAR are consistent with previous RBL trial results, indicating that RBL is effective and safe for preventing rCDI through 8 weeks after administration in real-world practice.

Background: While much of cancer research has historically centered on innovations within clinical or laboratory settings, most of the factors shaping equity in cancer outcomes reside outside hospital walls—in neighborhoods, workplaces, and community networks. This reality underscores the need for community-involved and community-living interventions: programs co-designed and delivered within communities to meet people where they live, work, and socialize . Such interventions hold the greatest promise for sustainability because they are embedded in the daily lives, cultures, and resources of the populations they serve. Methods: This special collection brings together research that illuminates the power of community-centered and community co-led strategies for prevention, early detection, treatment, and survivorship across diverse settings. Results: The articles in this series illustrate how innovation, cultural humility, and local engagement can bridge persistent gaps in cancer care. Conclusion: Together, they highlight how communities themselves are essential partners in dismantling disparities and achieving lasting cancer control.

Abstract Background Despite advancements in care, pregnant individuals with congenital heart disease (CHD) face disproportionately high risks. Objectives To address these challenges, a national consortium was established to improve maternal outcomes in CHD through multidisciplinary collaboration and patient engagement. Study design As part of a 2.5‐year multi‐phase consortium initiative, an in‐person research summit followed by three virtual focus groups (Project PHASE 3) was conducted with patients, clinicians, researchers, advocates, and policy representatives. Qualitative data were collected, and reflexive thematic analysis was performed to identify shared priorities. Results A total of 48 individuals participated in the in‐person meeting, including 18 patients (83% female; 11% Black/African American, 17% Asian, 11% Hispanic, 61% White) and 30 clinicians/researchers. An additional 19 patients (100% female; 32% rural/non‐urban; 16% Black/African American, 10% Hispanic, 74% White) participated in virtual focus groups. Key priorities identified included improved patient–healthcare provider communication, expanded access to multidisciplinary and adult CHD‐specialized care, and greater inclusion of patient voices in reproductive planning and research. Focus groups underscored racial disparities in care, limited CHD education for patients of color, and the need for culturally tailored resources. Participants emphasized the importance of representative research cohorts, integration of genetic counseling, and dissemination of research in accessible, plain‐language formats. Conclusions Findings demonstrate the value of integrating patient expertise and partnership in shaping cardio‐obstetric research, care models, and education. Addressing maternal health concerns in CHD research requires both structural changes and community‐driven, inclusive research strategies.

Abstract Background The incidence of type 2 diabetes mellitus among young adults has been increasing over the past few decades. There are limited data on contemporary national cardiovascular mortality rates in young adults with diabetes mellitus (DM). Methods We queried the Centers for Disease Control and Prevention's Wide‐Ranging Online Data for Epidemiologic Research database for patients aged 15 to 44 years from 1999 to 2019 in the primary analysis. A secondary analysis included data from 2020 to 2022 to examine the effect of the COVID‐19 pandemic. We analysed patients in whom cardiovascular diseases (CVD) were listed as the main cause of death and DM as a contributing cause of death. In calculating age‐adjusted mortality rates (AAMR) per 100 000 individuals, we used CVD mortality in young adults with comorbid diabetes as the numerator and the overall population as the denominator. We determined temporal trends by estimating the average annual percent change (AAPC) using the Joinpoint regression program. Results Among 3 309 079 individuals aged 15–44 years who died, 30 978 deaths were due to CVD with comorbid DM listed as a contributing cause. The overall AAMR increased from 1.08 per 100 000 individuals in 1999 to 1.23 per 100 000 individuals in 2019, with an average APC of 0.75 (95% CI, 0.31–1.20). Compared with 1999, the percentage increase in CVD deaths in 2019 among young adults with comorbid DM was +6.2%, whereas a decrease of 19.9% was observed among those without comorbid DM. Males had a higher AAMR than females (1.60 vs. 0.97). Non‐Hispanic Black individuals and non‐Hispanic American Indian/Alaska Native individuals had the highest AAMRs of 2.99 and 2.89, respectively. The AAMR was higher in rural regions compared to urban areas (1.63 vs. 1.23). The overall AAMR increased markedly from 1.23 in 2019 to 1.60 in 2022, with a similar pattern observed across demographic subgroups. Conclusion Our study reveals a rising trend in CVD mortality in young adults with DM as a contributing cause. Males, non‐Hispanic Black individuals, and individuals from rural regions had higher AAMR than their counterparts. This warrants the development of specific healthcare policies aimed at these at‐risk populations. Lay summary Our study shows that cardiovascular disease (CVD) deaths are increasing in young adults with diabetes mellitus listed as a contributing cause.
