OBJECTIVE Sepsis is associated with significant morbidity and mortality in pediatric hematology, oncology, and transplant (PHOT) patients. This study characterized PHOT patients who developed hospital-onset sepsis more than 12 hours after admission and identified risk factors for 30-day sepsis-attributable (SA) mortality. PATIENTS AND METHODS We analyzed an existing multicenter database of sepsis collected prospectively over 5 years (2017–2021) as part of the Improving Pediatric Sepsis Outcomes Collaborative. Sepsis was defined using operational elements documented in the health records based on International Classification of Diseases, Tenth Revision codes, treatment, diagnostic tests, and sepsis screen, huddle, or order set use. RESULTS A total of 9604 sepsis episodes in PHOT patients from 49 hospitals were analyzed: 70.5% were identified in the emergency department (ED), 10.9% in inpatient settings less than or equal to 12 hours from admission, and 18.6% were hospital onset. Only 52.5% of patients with hospital-onset sepsis were identified using a sepsis recognition method compared with 87.2% in the ED (P < .001). The overall 30-day SA mortality was 2.2%, with a higher rate (6.9%) among those with hospital-onset sepsis compared with those who developed sepsis at presentation or less than or equal to 12 hours (1.1%, P < .001). CONCLUSIONS Although the difference in SA mortality between hospitalized and nonhospitalized patients may be impacted by nonmeasurable confounders inherent to the type of patients presenting in the different care settings, we reported system-based improvements that may reduce mortality. The 30-day SA mortality was lower in hospitalized PHOT patients when sepsis was detected by early recognition methods, supporting the need for efforts to implement sepsis recognition tools in the inpatient setting.

Background. The current model for end-stage liver disease (MELD) exception policies for portopulmonary hypertension (POPH) require serial right heart catheterizations (RHCs) every 3 mo to maintain exception points. RHC is necessary for the initial diagnosis of POPH, but the utility of serial catheterizations has not been studied. In patients with POPH MELD exceptions, we sought to compare noninvasive and invasive hemodynamics and determine the sensitivity of echocardiography for the detection of hemodynamically severe POPH that would preclude liver transplant. Methods. We performed a single-center retrospective cohort study of patients with POPH MELD exceptions who underwent liver transplant from December 2008 to January 2024. Results were validated at an external center. Echocardiograms and RHCs performed within 1 mo were compared. Pearson correlation coefficient and Bland-Altman plots assessed the association between echocardiogram and RHC variables. We examined varied echocardiographic parameters to optimize sensitivity for the detection of hemodynamically severe POPH. Results. Twenty-two individuals underwent 60 follow-up RHCs with paired echocardiograms. Right ventricular systolic pressure (RVSP) and cardiac index estimated with echocardiogram were not strongly correlated with RHC measurements at follow-up (RVSP and RHC pulmonary artery systolic pressure: R = 0.30, P = 0.02; cardiac index: R = 0.17, P = 0.21). However, echocardiograms with RVSP ≥48 mm Hg had 100% sensitivity for detecting hemodynamically severe POPH, with 100% negative predictive value. In external validation of 13 paired echocardiograms and RHCs, our algorithm had 64% specificity and 100% negative predictive value. Conclusions. Although echocardiogram and RHC hemodynamic estimates were not strongly correlated, these results could potentially negate the current requirement for repeat RHC every 3 mo to maintain POPH MELD exception.

Migraine with aura(MwA) is associated with an increased risk of stroke and adverse vascular outcomes compared to those with migraine without aura (MwoA). AI-ECG prediction models developed at our institution can evaluate the probability of atrial fibrillation (AF) and estimate a patient’s age based on a normal sinus rhythm (NSR) ECG. Delta age, AI-ECG estimated age minus chronological age, indicates endothelial dysfunction and is associated with cardiovascular mortality. We aim to assess how AI-ECG prediction model outputs, specifically the AF probability and delta age, are associated with adverse vascular outcomes in patients with migraine. Adult patients diagnosed with MwA and MwoA from 2000-2020 with at least one digital, standard 12-lead ECG were identified. The first ECG that showed NSR is used as the index ECG. Patients with any adverse vascular outcomes before the index ECG were excluded. Adverse vascular outcomes used as endpoints include acute ischemic stroke, acute myocardial infarction, deep vein thrombosis/pulmonary embolism, AF, and carotid artery dissection. A total of 31301 patients (13783 MwA, 17518 MwoA) were included in our analysis. The mean age at the time of the index ECG was 44.3 (14.5), and the average follow-up time was 71.6 (69.8) months. Based on the index ECG, the mean AF probability was significantly higher in MwA compared to MwoA (2.39 vs 2.06, p< 0.001), while the delta age was lower in MwA compared to MwoA (3.7 vs 4.2, p <.001). The prevalences of all vascular outcomes are summarized in Table 1. Multivariate Cox regression models showed that a higher AF prediction model output (every 10% increase), as well as a higher delta age (every 10-year increase), are associated with an increased risk of composite vascular outcomes (HR1.20, 95%CI 1.17-1.23, p<.001, and HR1.19, 95%CI 1.14-1.23, p < .001) [Table 2]. The Kaplan-Meier curve of adverse vascular outcome-free survival by AF prediction model output, using 1% as the cutoff (HR 1.49, 95% CI 1.41, 1.57, p<.001), and by delta age, using 2-year as the cutoff (HR 1.14, 95% CI 1.08, 1.21, p <. 001) are presented in Figure 1. Having aura, older age, male, coronary artery disease, congestive heart failure, diabetes, hypertension, and tobacco use were also associated with a higher risk of adverse vascular outcomes. Our results demonstrated the potential of using AI-ECG AF prediction model output and delta age to identify migraine patients at risk for adverse vascular outcomes.

Key Points Studies on GFR assessment in people with cancer are needed. In this study, the creatinine–cystatin C equations performed better than other equations, and this was observed in solid and hematological cancers. Our findings give support to the preferential use of creatinine and cystatin C–based equations in people with cancer. Background GFR assessment is important in clinical practice with implications for diagnosis, prognostication, and drug dosing. People with cancer are at risk of imprecision in GFR estimation. This cross-sectional study evaluated the performance of various creatinine and cystatin C–based equations in comparison with measured GFR (mGFR) in people with cancer. Methods We retrieved data for all adult patients who had mGFR by urinary iothalamate clearance between 2011 and 2023 at Mayo Clinic and use of an electronic health record diagnosis code for cancer within 2 years before mGFR. The CKD Epidemiology Collaboration (CKD-EPI), European Kidney Function Consortium, and Cockcroft–Gault equations were computed, along with performance metrics (bias, precision, and root mean square error [RMSE]. Confidence intervals were generated by bootstrapping, and analysis were stratified by solid and hematological cancers. Results From all adults with cancer and mGFR, 1145 had both creatinine and cystatin C available within 7 days of mGFR. Among all equations, the creatinine–cystatin C CKD-EPI equation provided the best performance, with small bias (median, 3.0; 95% confidence interval, 2.3 to 3.8) and higher precision (RMSE, 14.5) compared with creatinine-only or cystatin C–only equations (RMSE varying from 16.6 to 20), and this was also true in solid and hematological cancers. The creatinine–cystatin European Kidney Function Consortium equation had a similar performance to CKD-EPI, Cockcroft–Gault showed worst precision (30% of people with errors above 30%), and cystatin C CKD-EPI equation was the most biased, prone to underestimation of mGFR. Conclusions In our cohort of patients with mGFR and cancer, the CKD-EPI creatinine–cystatin C equation performed best for GFR assessment, and this was true for both solid and hematological cancers. Our findings give support for the preferential use of creatinine and cystatin C–based equations instead of creatinine-only or cystatin C–only equations in people with cancer.

TPS309 Background: Patients with oligometastatic colorectal cancer (CRC) often experience long-term progression-free survival and overall survival (OS) following aggressive local treatment of isolated metastases, especially in the liver. However, the effectiveness of local ablative therapies, such as microwave ablation (MWA) and stereotactic body radiation therapy (SBRT), in patients with inoperable limited metastatic CRC or those with additional metastases outside the liver or lungs, remains uncertain. Despite the historical use of local therapy for oligometastatic CRC, often influenced by provider bias rather than strong evidence, questions persist about the potential benefits of applying this approach to patients with more extensive disease. This trial aims to address this clinical challenge by evaluating the safety and efficacy of adding total ablative therapy (TAT) of all disease sites to standard systemic treatment in patients with limited metastatic CRC. Methods: A022101/NRG-GI009 is a randomized phase III study within the National Clinical Trials Network, set to enroll 364 patients with newly diagnosed metastatic CRC (BRAF wild-type, microsatellite stable). Patients with liver-only metastatic disease are excluded. Pre-registration during first-line systemic therapy induction is encouraged. Eligible lesions must be treatable with surgical resection, MWA, and/or SBRT. Patients without significant radiographic progression after 12-39 weeks of first-line systemic therapy, with 4 or fewer disease sites post-induction chemotherapy, will be randomized 1:1. Randomization will be stratified by the number of metastatic organ sites (1-2 vs. 3-4), timing of metastatic disease diagnosis (de novo vs. secondary), and the presence of metastatic disease outside the liver/lungs in at least one site. Patients in Arm 1 will receive TAT, targeting all metastatic sites with a combination of surgical resection, MWA, and/or SBRT, followed by standard systemic therapy. Patients in Arm 2 will continue with standard systemic therapy alone. The choice of systemic therapy is at the discretion of the medical oncologist and may include continued therapy, maintenance chemotherapy, or observation. The primary endpoint is OS, with secondary endpoints including event-free survival, treatment-related toxicities, and local recurrence. Exploratory biomarker analyses will also be conducted. The study requires 346 evaluable patients across the two arms to demonstrate an OS improvement with a hazard ratio of 0.7, providing 80% power with a one-sided alpha of 5%. The trial employs a group sequential design with two interim analyses (at 25% and 50% of events) to assess futility. The trial began in January 2023, and patient recruitment is ongoing.

PURPOSE Over 50% of households in the United States have at least one musician—many musicians are also breast cancer survivors. This group has not been well studied, and given the level of fine sensory-motor skill required for musicianship, we hypothesized that musicians experience unique manifestations of breast cancer treatment toxicities. METHODS A nine-item Musical Toxicity Questionnaire (MTQ) was distributed to patients who had consented to participate in the Mayo Clinic Breast Cancer Registry. The MTQ screened participants by asking if they played a musical instrument or sang in the last 10 years: questions populated for those who answered yes. Respondents were asked if they noticed difficulty with their musical endeavor during or after breast cancer treatment, defined as acute musical toxicity (AMT). The questionnaire asked which side effect and cancer-directed therapy most influenced musical ability, what musical attributes were affected, and the timeline of resolution. Multivariable and classification tree analyses assessed relationships between AMT and treatment characteristics. RESULTS Of 1,871 survey respondents, 29% (535/1,871) self-identified as musicians. Over a quarter (27%, 144/535) reported AMT, and for 57% (82/144), AMT had not resolved at the time of survey. Of the treatments each participant received, chemotherapy was most often reported as most negatively impactful (63/89 who received chemotherapy, 71%). Decreased endurance was the most common musical difficulty (64% of those with AMT, 92/144), followed by decreased accuracy, trouble playing/singing quickly, and difficulty using proper technique. Multivariable and classification tree analyses revealed that receipt of chemotherapy was most strongly correlated with AMT. CONCLUSION These results will help oncology care teams counsel musicians, answer questions about impacts on musicality, and provide a timeline for resolution of musical symptoms.

AbstractBackgroundIndividuals with spinal cord injury (SCI) commonly have autonomic dysreflexia (AD) with increased sympathetic activity. After SCI, individuals have decreased baroreflex sensitivity and increased vascular responsiveness.ObjectiveTo evaluate the relationship between baroreflex and blood vessel sensitivity with AD symptoms.DesignCase control.SettingTertiary academic center.Patients14 individuals with SCI, 17 matched uninjured controls.InterventionsAll participants quantified AD symptoms using the Autonomic Dysfunction Following SCI (ADFSCI)‐AD survey. Participants received three intravenous phenylephrine boluses, reproducibly increasing systolic blood pressure (SBP) 15–40 mmHg. Continuous heart rate (R‐R interval, ECG), beat‐to‐beat blood pressures (Finapres), and popliteal artery flow velocity were recorded. Vascular responsiveness (α1 adrenoreceptor sensitivity) and heart rate responsiveness to increased SBP (baroreflex sensitivity) were calculated.Main Outcome MeasuresBaroreflex sensitivity after increased SBP; Vascular responsiveness through quantified mean arterial pressure (MAP) 2‐minute area under the curve and change in vascular resistance.ResultsSCI and control cohorts were well matched with mean age 31.9 and 29.6 years (p = .41); 21.4% and 17.6% female, respectively. Baseline MAP (p = .83) and R‐R interval (p = .39) were similar. ADFSCI‐AD scores were higher following SCI (27.9 ± 22.9 vs. 4.2 ± 2.9 in controls, p = .002). To quantify SBP response, MAP area under the curve was normalized to dose/body weight. Individuals with SCI had significantly larger responses (0.26 ± 0.19 mmHg*s/kg*μg) than controls (0.06 ± 0.06 mmHg*s/kg*μg, p = .002). Similarly, leg vascular resistance increased after SCI (24% vs. 6% to a normalized dose, p = .007). Baroreflex sensitivity was significantly lower after SCI (15.0 ± 8.3 vs. 23.7 ± 9.3 ms/mmHg, p = .01). ADFSCI‐AD subscore had no meaningful correlation with vascular responsiveness (R2 = 0.008) or baroreflex sensitivity (R2 = 0.092) after SCI.ConclusionsAlthough this confirms smaller previous studies suggesting increased α1 adrenoreceptor sensitivity and lower baroreflex sensitivity in individuals with SCI, contrary to our hypothesis these differences lacked correlation to increased symptoms of AD. Further research into physiologic mechanisms is needed to explain why some individuals with SCI develop symptoms.

Abstract BACKGROUND We sought to characterize the cognitive profile among individuals with mild cognitive impairment with Lewy bodies (MCI‐LB) to help guide future clinical criteria. METHODS Systematic review and meta‐analysis included MCI‐LB studies with cognitive data from PubMed, Embase, Web of Science, and PsycINFO (January 1990 to March 2023). MCI‐LB scores were compared to controls, MCI due to Alzheimer's disease (MCI‐AD), and dementia with Lewy bodies (DLB) groups with random‐effects models. RESULTS We included 26 studies and 2823 participants. Across all domains, the MCI‐LB group performed worse than controls and better than DLB. Compared to MCI‐AD, the MCI‐LB group performed worse in attention/processing speed ( g = –0.24, 95% confidence interval [CI]: –0.35, –0.12), attention/executive ( g = –0.42, 95% CI: –0.56, –0.28); better in verbal immediate recall ( g = 0.37; 95% CI: 0.15, 0.59) and delayed memory ( g = 0.40; 95% CI: 0.22, 0.58). DISCUSSION The cognitive profiles in MCI‐LB and MCI‐AD are consistent with established profiles in DLB and AD. Neuropsychological assessment may be helpful in differential diagnosis, even in early disease states. Highlights We performed a systematic review and meta‐analysis for cognition in mild cognitive impairment with Lewy bodies (MCI‐LB). Compared to MCI due to Alzheimer's disease (MCI‐AD), MCI‐LB had worse attention, executive function, and processing speed. Compared to MCI‐AD, MCI‐LB had better verbal immediate and delayed recall. The MCI‐LB group was worse on all cognitive domains than controls, and better than dementia with Lewy bodies. Studies used different tests and there is a need for global efforts for harmonization.
