Background: Left ventricular (LV) injury is a cardioembolic etiology of ischemic stroke. We aimed to 1) evaluate recurrent stroke risk among patients with cryptogenic stroke and LV injury, and 2) determine if there is a treatment effect with anticoagulation in this population. Methods: We analyzed the multicenter, retrospective Cardiac Abnormalities in Stroke Prevention and Recurrence cohort of patients with cryptogenic ischemic stroke. The exposure was LV injury defined by 1) LV ejection fraction (EF) 20-40% and/or 2) LV wall motion abnormality (hypokinesis or akinesis). The primary composite outcome included recurrent stroke, major bleeding, or death. Cox proportional hazard models were built and sequentially adjusted for 1) age and sex (Model 1), and 2) age, sex, race, ethnicity, anti-thrombotic use, and vascular risk factors (Model 2). We then assessed if there was heterogeneity in treatment effect by LV injury status with an interaction term of LV injury and oral anticoagulation use in Model 2. Results: Of 2,641 patients in CASPR, the analytic cohort included 2,191 patients with complete exposure and outcome data (median age 65 years, 49.8% female, median follow-up 1.55 years). There were 113 (5.2%) patients with LV injury (median LVEF 30%, interquartile range 25-34%). There were 559 incident events (321 recurrent strokes [288 ischemic], 71 major hemorrhages, 250 deaths). Among patients with LV injury, 15.9% were prescribed an anticoagulant within 7 days of index stroke (vs 9.6% without LV injury, p=0.03). The unadjusted risk of the primary outcome was non-significantly higher among patients with LV injury vs without (HR 1.40; 95% confidence interval [CI], 0.98-2.00), but became significant in Model 1 (HR 1.50; 95% CI, 1.21-1.85) and in Model 2 (HR 1.35, 95% CI, 1.11-1.64). In the LV injury subgroup, anticoagulation vs antiplatelet therapy was associated with a significant reduction in the primary outcome (HR 0.63, 95% CI, 0.43-0.94). In patients without LV injury, anticoagulation was associated with a higher risk of the composite outcome (HR 4.35, 95% CI, 1.69-11.16, p[interaction]=0.002). Conclusion: In this observational study, there was an increased risk of the primary outcome which included recurrent stroke among patients with cryptogenic stroke and LV injury. Anticoagulation use in LV injury is associated with a significant reduction in the risk of the primary outcome. These findings warrant confirmation in a dedicated randomized controlled trial.

Introduction: Malignancy represents an important subgroup of embolic stroke of undetermined source (ESUS). We aim to compare infarct features, potential embolic sources, and long-term outcomes in ESUS patients with and without malignancy. Methods: In this pre-specified secondary analysis of the Cardiac Abnormalities in Stroke Prevention and Recurrence (CASPR) retrospective cohort study, active cancers were identified by site investigators and adjudicated as malignant if they were non-squamous or non-basal cell skin cancers. We compared the prevalence of various potential embolic sources (e.g., patent foramen ovale, left ventricular dysfunction, post-stroke atrial fibrillation) among patients with and without malignancy. The risk of recurrent stroke, major bleeding, or death was evaluated using adjusted Cox proportional hazards models, accounting for age, sex, vascular risk factors, competing potential embolic sources, and initial treatment with anticoagulation versus non-anticoagulant (e.g., antiplatelet) regimen. Results: Of the 2201 patients followed over a median of 564 days, 236 (10.7%) were diagnosed with cancer at the time of stroke. Patients with malignancy were older, more frequently hypertensive and did not differ with regards to prevalence of specific infarct patterns or potential cardiac embolic sources. No difference was observed in the composite outcome of recurrent stroke, major bleeding, or death (adjusted HR 1.02, 95% CI, 0.71-1.46). Age (adjusted HR per year 1.02, 95% CI, 1.01-1.03), baseline stroke severity (adjusted HR 1.03 per NIHSS point, 95% CI, 1.01-1.05), prior stroke (adjusted HR 1.68, 95% CI, 1.38-2.05), and multi-territorial infarct pattern (adjusted HR 1.67, 95% CI, 1.33-2.08) were significantly associated with this composite outcome, but anticoagulation was not. There was a nominally lower rate of major bleeding with malignancy (adjusted HR 0.45, 95% CI, 0.19-1.04), a significantly higher rate of death (adjusted HR 1.58, 95% CI, 1.09-2.30), but no significant difference in recurrent ischemic stroke (p=0.31). Conclusions: Patients with malignancy and ESUS had higher mortality but did not differ in recurrent stroke risk or major bleeding when compared to patients without malignancy. Anticoagulation was not independently associated with better outcomes. Further analysis of infarct topology and risk factors may better identify patients for whom anticoagulation may benefit.

Introduction Although the prevalence of chemotherapy-induced peripheral neuropathy (CIPN) has been reported, the proportion of patients with CIPN who report chronic moderate-to-severe neuropathy or chronic painful neuropathy remains poorly understood, despite its significant impact on patients’ quality of life and treatment outcomes. Methods A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome was the pooled prevalence of chronic (≥3 months) moderate-to-severe CIPN or painful CIPN among patients diagnosed with CIPN. Estimates from each study were transformed using a double-arcsine transformation and pooled in a meta-analysis using an inverse variance heterogeneity model. Subgroup analysis was conducted based on geographical region, sex, chemotherapy regimen, primary cancer type, and funding source; metaregression analysis was conducted based on study design, human development index (HDI), and publication year. Results 76 studies from 29 countries, encompassing 13 635 patients with CIPN, were included. Among patients diagnosed with CIPN, the pooled prevalence of those reporting chronic moderate-to-severe CIPN or painful CIPN was estimated at 47.76% (95% CI 37.50 to 58.08; 95% prediction interval 24.68–71.84). Substantial heterogeneity was observed across studies ( I² =97.45%; 95% CI for I 2 97.15 to 97.72). Subgroup analysis revealed that patients treated with platinum-based agents and taxanes had the highest prevalence of chronic moderate-to-severe CIPN or painful CIPN (44.47% and 55.68%, respectively), and among primary cancers, those with breast cancer, multiple myeloma, and lung cancer reported the highest prevalence of chronic moderate-to-severe CIPN or painful CIPN (61.31%, 53.55%, and 50.85%, respectively). Study design, HDI, and publication year were non-significant moderators of prevalence estimates. Based on our Grading of Recommendations, Assessment, Development, and Evaluation assessment, the certainty of evidence was considered “very low.” Sensitivity analysis restricted to studies explicitly measuring painful CIPN (40.78%; 95% CI 29.08 to 52.74) or moderate-to-severe CIPN (49.04%; 95% CI 37.16 to 60.95) yielded similar prevalence estimates. Conclusion This study provides the first comprehensive global estimate of the prevalence of chronic moderate-to-severe CIPN or painful CIPN, highlighting its significant burden on patients worldwide. The variation in prevalence across geographical regions, chemotherapy regimens, and primary cancers underscores the need for tailored management strategies and further research to address potential disparities.

AbstractBackgroundInflammatory bowel disease (IBD) affects more than 10 million people worldwide. Men and women are equally affected by Crohn's disease (CD). It has been shown that patients with CD are at an increased risk of a colorectal cancer (CRC) diagnosis and CRC‐related mortality. During the last two decades, biological therapies have revolutionized the treatment of CD. There are no current studies investigating the prevalence of CRC in patients with CD in the era of biological therapy and the possible features of patients with CD who are at high risk of developing CRC.AimWe aim to assess the prevalence of CRC, risk factors and profile of CRC in patients with CD receiving biological treatment compared with those who are not under biological therapy and the impact of CD‐associated colorectal strictures on CRC development. The study hypothesis is that the use of biological therapy in the control of CD activity may decrease the risk of developing CRC.Study design and settingAn international, retrospective, snapshot of the prevalence of CRC in patients with CD, reported according to the SPIRIT guidelines. The study will involve centres that hold regular IBD multidisciplinary team meetings and have both IBD colorectal surgeons and gastroenterologists. Each participating centre will provide a local consultant lead and a local trainee lead. Data will be collected within a 2‐year recruitment period (January 2017–January 2019).Study populationAdult patients who presented with CD during the study period. Patients with an incidental diagnosis of CD during evaluation for CRC will be excluded.Statistical planBaseline patient characteristics will be summarized using the appropriate descriptive statistics. Univariable, multivariable and Cox regression models will be used to identify factors significantly associated with CRC. For noncontinuous variables a comparison between the subgroups will be carried out using the chi‐square test corrected by Fisher's exact test if appropriate. A p‐value of <0.05 will be considered statistically significant.Data storageData will be stored on a secured server, pin‐code protected according to the local data management agreement.

ObjectiveThe ADVOCATE trial demonstrated that treatment of active granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) with avacopan was noninferior in achieving remission at week 26 and superior for sustained remission at week 52 compared with a prednisone taper. This analysis of ADVOCATE evaluated the efficacy and safety of avacopan in patients with ear, nose, throat (ENT), or lung manifestations.MethodsThis post hoc analysis included patients enrolled in ADVOCATE with ENT or lung manifestations at baseline. Outcomes included remission at weeks 26 and 52, respiratory tract manifestations over time, relapse rate, glucocorticoid‐related toxicity, health‐related quality of life (HRQoL), and safety.ResultsADVOCATE included 144 patients with ENT manifestations (avacopan: n = 75, prednisone taper: n = 69) and 142 with lung manifestations (avacopan: n = 71, prednisone taper: n = 71). Among patients with ENT manifestations, remission was achieved at week 26 by 72.0% (avacopan group) and 71.0% (prednisone taper group) and was sustained at week 52 by 62.7% (avacopan) and 53.6% (prednisone taper). Among patients with lung manifestations, remission was achieved at week 26 by 73.2% (avacopan) and 66.2% (prednisone taper) and sustained at week 52 by 67.6% (avacopan) and 53.5% (prednisone taper). The relapse rate, glucocorticoid toxicity, and measures of HRQoL favored avacopan for both respiratory tract manifestation groups. Safety was comparable across treatment groups.ConclusionPatients with GPA or MPA with ENT or lung manifestations demonstrated similar responses to avacopan, reflecting results reported in the overall ADVOCATE trial population and supporting the administration of avacopan in these subgroups.

Importance The emergency department (ED) offers an opportunity to initiate palliative care for older adults with serious, life-limiting illness. Objective To assess the effect of a multicomponent intervention to initiate palliative care in the ED on hospital admission, subsequent health care use, and survival in older adults with serious, life-limiting illness. Design, Setting, and Participants Cluster randomized, stepped-wedge, clinical trial including patients aged 66 years or older who visited 1 of 29 EDs across the US between May 1, 2018, and December 31, 2022, had 12 months of prior Medicare enrollment, and a Gagne comorbidity score greater than 6, representing a risk of short-term mortality greater than 30%. Nursing home patients were excluded. Intervention A multicomponent intervention (the Primary Palliative Care for Emergency Medicine intervention) included (1) evidence-based multidisciplinary education; (2) simulation-based workshops on serious illness communication; (3) clinical decision support; and (4) audit and feedback for ED clinical staff. Main Outcome and Measures The primary outcome was hospital admission. The secondary outcomes included subsequent health care use and survival at 6 months. Results There were 98 922 initial ED visits during the study period (median age, 77 years [IQR, 71-84 years]; 50% were female; 13% were Black and 78% were White; and the median Gagne comorbidity score was 8 [IQR, 7-10]). The rate of hospital admission was 64.4% during the preintervention period vs 61.3% during the postintervention period (absolute difference, −3.1% [95% CI, −3.7% to −2.5%]; adjusted odds ratio [OR], 1.03 [95% CI, 0.93 to 1.14]). There was no difference in the secondary outcomes before vs after the intervention. The rate of admission to an intensive care unit was 7.8% during the preintervention period vs 6.7% during the postintervention period (adjusted OR, 0.98 [95% CI, 0.83 to 1.15]). The rate of at least 1 revisit to the ED was 34.2% during the preintervention period vs 32.2% during the postintervention period (adjusted OR, 1.00 [95% CI, 0.91 to 1.09]). The rate of hospice use was 17.7% during the preintervention period vs 17.2% during the postintervention period (adjusted OR, 1.04 [95% CI, 0.93 to 1.16]). The rate of home health use was 42.0% during the preintervention period vs 38.1% during the postintervention period (adjusted OR, 1.01 [95% CI, 0.92 to 1.10]). The rate of at least 1 hospital readmission was 41.0% during the preintervention period vs 36.6% during the postintervention period (adjusted OR, 1.01 [95% CI, 0.92 to 1.10]). The rate of death was 28.1% during the preintervention period vs 28.7% during the postintervention period (adjusted OR, 1.07 [95% CI, 0.98 to 1.18]). Conclusions and Relevance This multicomponent intervention to initiate palliative care in the ED did not have an effect on hospital admission, subsequent health care use, or short-term mortality in older adults with serious, life-limiting illness.

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous soft tissue sarcoma and affects an estimated 1,500 people annually in the United States. DFSP frequently exhibits extensive local infiltration. Initial treatment is through surgical excision, and care should be taken to ensure that negative margins are achieved to minimize recurrence. Although DFSP has a reported high rate of recurrence, metastasis is more uncommon. Fibrosarcomatous DFSP is an aggressive variant with an increased risk for local recurrence and metastasis. If achieving negative margins or resection is not feasible, radiation therapy or systemic treatment are options that may be considered by a multidisciplinary team. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) outline recommended treatment options available for DFSP.

Background: Chordoma is a rare bone cancer with limited treatment options. Clinical trials are crucial for developing effective therapies, but their success depends on including diverse patient populations. The objective of this study was to systematically evaluate the reporting of racial, ethnic, and socioeconomic diversity in United States clinical trials exploring treatment for chordoma. Methods: A literature search was conducted through PubMed/Medline, Cochrane, Epistemonikos, and ClinicalTrials.gov databases for published US chordoma trials up until 19 August 2024. The data collected included trial characteristics and racial and ethnic data, as well as socioeconomic indicators when available. Methodological Index for Non-Randomized Studies (MINORS) and Revised Cochrane Risk-of-Bias Tool for Randomized Trials (RoB2) analyses were adopted to assess the methodological quality. The N-1 Chi-squared (χ2) test was implemented to compare the reported racial and ethnic data with the most recent US Census Bureau data. Results: Five trials involving 111 patients (median age: 63 years; 34% female) were included. Four studies (80%) were single-arm non-randomized studies with one study (25%) having a high methodological quality and three (75%) having a moderate quality based on the MINORS analysis. Most patients (91%, n = 82) were White/Caucasian, representing a proportion which was significantly higher than the reported 75% in the US population (p = 0.0005). Black/African American patients (2%, n = 2) were significantly underrepresented compared to the 14% in the US population (p = 0.0015). Regarding ethnicity, Hispanic/Latino patients (7%, n = 6) were significantly underrepresented compared to the 20% in the US population (p = 0.0021). No measures of socioeconomic status were reported. Conclusions: This systematic review highlighted the need for improved racial and ethnic diversity in chordoma trials and the better reporting of socioeconomic data. The underrepresentation of minority groups may obscure potential disparities in disease incidence, treatment access, and clinical outcomes.

INTRODUCTION: Patients with ulcerative colitis (UC) and prior biologic failure may have reduced or delayed efficacy with subsequent advanced therapies. This analysis evaluated the efficacy and safety of ozanimod during the True North (TN) study and its open-label extension (OLE) in biologic-exposed patients with UC. METHODS: TN was a randomized, placebo-controlled 52-week trial (10-week induction, 42-week maintenance period). Eligible patients could enter the OLE. Clinical outcomes were assessed at TN week (W) 10 and W52 and OLE W46 and W94. Symptomatic efficacy was evaluated through induction and in the OLE until W94. Safety was assessed. RESULTS: This analysis included 376 biologic-exposed patients. In the placebo-controlled cohort, more ozanimod-treated patients achieved clinical response than placebo at W10 regardless of the number or type of prior biologics; patients who used 1 vs ≥2 prior biologics achieved higher efficacy rates. Efficacy rates were higher at W52 than W10 and were similar across subgroups regardless of the number or type of prior biologics. Significantly greater proportions of ozanimod vs placebo patients achieved symptomatic response by W5 ( P = 0.0173) and symptomatic remission by W10 ( P = 0.0207). Among biologic-exposed TN W10 ozanimod nonresponders who entered the OLE, 61% achieved symptomatic response with an extra 10 weeks of ozanimod treatment. Ozanimod efficacy was durable for ∼3 years of continuous treatment in biologic-exposed W52 clinical responders who entered the OLE. No new safety signals were observed. DISCUSSION: Ozanimod was effective and safe in biologic-exposed patients with UC, but these patients may require more time to respond to treatment.

Background: Previous research has reported higher rates of both injury and illness among Paralympic athletes compared with Olympic athletes during the Winter Olympic and Paralympic Games, but no studies have directly compared injury and illness incidence between Olympic and Paralympic athletes competing in a Summer Games. Purpose: To compare injury and illness rates between Olympic and Paralympic Team USA athletes competing in the Tokyo 2020 Olympic and Paralympic Games. Study Design: Descriptive epidemiology study. Methods: All injuries and illnesses that occurred among the Team USA athletes competing in the Tokyo 2020 Summer Olympic or Paralympic Games were documented. A total of 701 Team USA athletes (53.6% female) competed in the Tokyo 2020 Summer Olympic Games, across 34 different sports. For the Tokyo 2020 Summer Paralympic Games, a total of 245 athletes (51.6% female) competed across 20 sports. Incidence rates (IRs) per 1000 athlete-days were calculated according to sex, sport, anatomic location, and illness type. IR ratios (IRRs) were calculated to compare IRs between male and female athletes and between Olympic and Paralympic athletes. Results: Overall, there were no differences in injury incidence (IRR, 1.18; 95% CI, 0.84-1.68) or illness incidence (IRR, 0.68; 95% CI, 0.41-1.15) between Olympic and Paralympic athletes. Male Paralympic athletes were less likely to sustain an illness compared with female Paralympic athletes (IRR, 0.35; 95% CI, 0.11-0.90). Conclusion: There were no differences in injury or illness rates between Olympic and Paralympic Team USA athletes competing at the Tokyo 2020 Summer Games, contrary to previous comparisons among winter sport athletes. These results challenge the prevailing notion that Summer Paralympic athletes are at greater injury and illness risk, suggesting that factors beyond Olympic or Paralympic Games participation influence health concerns.
