Objective Open science is a movement and set of practices to conduct research more transparently. Implementing open science will significantly improve public access and supports equity. It also has the potential to foster innovation and reduce duplication through data and materials sharing. Here, we survey an international group of researchers publishing in cardiovascular journals regarding their perceptions and practices related to open science. Methods We identified the top 100 ‘Cardiology and Cardiovascular Medicine’ subject category journals from the SCImago journal ranking platform. This is a publicly available portal that draws from Scopus. We then extracted the corresponding author’s name and email from all articles published in these journals between 1 March 2021 and 1 March 2022. Participants were sent a purpose-built survey about open science. The survey contained primarily multiple choice and scale-based questions for which we report count data and percentages. For the few text-based responses we conducted thematic content analysis. Results 198 participants responded to our survey. Participants had a mean response of 6.8 (N=197, SD=1.8) on a 9-point scale with endpoints, not at all familiar (1) and extremely familiar (9), when indicating how familiar they were with open science. When asked about where they obtained open science training, most participants indicated this was done on the job self-initiated while conducting research (n=103, 52%), or that they had no formal training with respect to open science (n=72, 36%). More than half of the participants indicated they would benefit from practical support from their institution on how to perform open science practices (N=106, 54%). A diversity of barriers to each of the open science practices presented to participants were acknowledged. Participants indicated that funding was the most essential incentive to adopt open science. Conclusions It is clear that policy alone will not lead to the effective implementation of open science. This survey serves as a baseline for the cardiovascular research community’s open science performance and perception and can be used to inform future interventions and monitoring.

Goals: Develop quality indicators for ineffective esophageal motility (IEM). Background: IEM is identified in up to 20% of patients undergoing esophageal high-resolution manometry (HRM) based on the Chicago Classification. The clinical significance of this pattern is not established and management remains challenging. Study: Using RAND/University of California, Los Angeles Appropriateness Methods, we employed a modified-Delphi approach for quality indicator statement development. Quality indicators were proposed based on prior literature. Experts independently and blindly scored proposed quality statements on importance, scientific acceptability, usability, and feasibility in a 3-round iterative process. Results: All 10 of the invited esophageal experts in the management of esophageal diseases invited to participate rated 12 proposed quality indicator statements. In round 1, 7 quality indicators were rated with mixed agreement, on the majority of categories. Statements were modified based on panel suggestion, modified further following round 2’s virtual discussion, and in round 3 voting identified 2 quality indicators with comprehensive agreement, 4 with partial agreement, and 1 without any agreement. The panel agreed on the concept of determining if IEM is clinically relevant to the patient’s presentation and managing gastroesophageal reflux disease rather than the IEM pattern; they disagreed in all 4 domains on the use of promotility agents in IEM; and had mixed agreement on the value of a finding of IEM during anti-reflux surgical planning. Conclusion: Using a robust methodology, 2 IEM quality indicators were identified. These quality indicators can track performance when physicians identify this manometric pattern on HRM. This study further highlights the challenges met with IEM and the need for additional research to better understand the clinical importance of this manometric pattern.

Introduction: Patients with coronary artery disease (CAD) are at increased risk of cognitive decline. A proposed mechanism is cerebral hypoperfusion related to vascular dysfunction and impaired cerebral blood flow regulation Hypothesis: Patients with CAD will have lower cerebrovascular function than age- and sex-matched controls, assessed as reactivity to a vasodilatory carbon dioxide (CO 2 ) stimulus. Methods: Adults 40-70years old with CAD were recruited on enrollment to a cardiac rehabilitation program following a cardiac event or hospitalization. Age and sex-matched adults without known disease or cardiovascular risk factors were recruited as healthy controls. Cognitive function was assessed by the Fluid Composite of the NIH Cognition Toolbox. Following a familiarization visit, participants underwent a stepped CO 2 protocol (room air, 2% CO 2 , 4% CO 2 , 6% CO 2 ) while continuously measuring middle cerebral artery velocity (MCAv) using transcranial doppler ultrasound, mean arterial pressure (MAP), ventilation (VE), and end-tidal CO 2 . Cerebrovascular conductance (CVCi) was calculated as MCAv/MAP. Cerebrovascular reactivity was calculated as the linear regression slope of CVCi against the change in end-tidal CO 2 . The reactivity of MAP and VE (or chemosensitivity) were also calculated. Results: 19 patients with CAD and 10 healthy controls were recruited ( Table 1 ). Compared with controls, patients with CAD had a 2-fold lower cerebrovascular reactivity (p=0.003), higher MAP reactivity (p<0.05), and a trend towards higher chemosensitivity (p<0.1) ( Table 2 ). There were no group differences in resting CVCi or cognition ( Table 2 ). After adjustment for age and sex, lower cerebrovascular reactivity was associated with lower peak oxygen uptake, diabetes, and smoking history ( Table 3 ). Conclusions: Compared with healthy controls, we report that patients with CAD have significantly lower cerebrovascular function, with no differences in cognitive function.

The NCCN Guidelines for Cervical Cancer provide recommendations for all aspects of management for cervical cancer, including the diagnostic workup, staging, pathology, and treatment. The guidelines also include details on histopathologic classification of cervical cancer regarding diagnostic features, molecular profiles, and clinical outcomes. The treatment landscape of advanced cervical cancer is evolving constantly. These NCCN Guidelines Insights provide a summary of recent updates regarding the systemic therapy recommendations for recurrent or metastatic disease.

Background Chimeric antigen receptor (CAR) T-cell therapies have recently been established as an important option for the management of relapsed/refractory (R/R) DLBCL. However, real-world studies suggest that approximately half of all patients (pts) receiving commercial CAR-T therapies will relapse within 6 months. These pts have a poor prognosis, with estimated overall survival (OS) of only 5 months, indicating a significant unmet need. Odronextamab is a novel, off-the-shelf, CD20×CD3 bispecific antibody that has demonstrated activity in both R/R follicular lymphoma and R/R DLBCL. We have previously reported encouraging results with odronextamab from the Phase 1 ELM-1 study (NCT02290951) in pts with R/R DLBCL post CAR-T therapy (Bannerji R, et al. Lancet Haematol. 2022). These results were consistent with the antitumor activity seen in pts with R/R DLBCL from the Phase 2 ELM-2 study (Kim WS, et al. ASH 2022). Here, we present an updated analysis of outcomes in a prespecified cohort of post CAR-T patients from ELM-1. Methods Intravenous odronextamab was administered weekly in 21-day cycles during Cycles (C) 1-4. Revisions to the step-up regimen were reported previously (Bannerji R, et al. Lancet Haematol. 2022). Odronextamab was administered with steroid prophylaxis and step-up doses of 0.7/4/20 mg during C1 to mitigate the risk of cytokine release syndrome (CRS), followed by 160 mg on Days (D) 1, 8, and 15 of C2-4. After C4, odronextamab maintenance treatment continued at 320 mg every 2 weeks until disease progression or unacceptable toxicity. Those pts who achieved a complete response (CR) that was durable for ≥9 months transitioned to dosing with 320 mg every 4 weeks. The primary endpoint was objective response rate (ORR), assessed by independent central review (ICR) according to the Lugano classification. Key secondary endpoints included duration of response (DoR), progression-free survival (PFS), and OS. Immune biomarker assessment was an exploratory endpoint. Results As of Dec 20, 2022, 46 pts were treated (safety-evaluable), with 44 pts evaluable for efficacy. For safety-evaluable pts, median age was 63 years (range 27-82), 67% male, 74% Ann Arbor stage III-IV, and 72% were refractory to CAR-T therapy administered in any prior line. 44 pts were evaluable for efficacy after 4.9 months median duration of follow-up. The ORR and CR rate by ICR were 48% (21/44) and 30% (13/44), respectively. Responses were durable, and both median DoR and median duration of CR were not reached. The probability of maintaining a response for 12 months was 62% and the probability of maintaining a CR for 9 months was 86%.A responder analysis of the subgroup of pts who achieved a CR will be presented. The CAR-T treated pts with DLBCL who were evaluable for biomarker analysis (n=10) had lower T-cell counts at baseline compared with CAR-T naive DLBCL pts (n=41 comparable pts who received odronextamab in ELM-2), yet the fold-change of T-cell expansion at C4D15 was greater in CAR-T treated pts versus CAR-T naive pts. T-cell dynamics, such as changes in activation, exhaustion, and memory subsets, will be presented. Safety was generally consistent with that previously reported. Six (13%) pts permanently discontinued odronextamab due to a treatment-emergent AE (device-related infection, pneumonia, dysphagia, gait disturbance, leukemia, and encephalopathy [n=1 each]). The most common treatment-emergent AE was CRS (any grade, 52%). The highest grade of CRS reported was Grade 2, and low-grade CRS events occurred in 46% of pts with the 0.7/4/20 mg step-up regimen. No cases of ICANS were reported in pts with the 0.7/4/20 mg regimen. Grade ≥3 infections occurred in 10 (22%) pts, with no Grade 5 events. No cases of tumor flare were reported. Conclusions Odronextamab monotherapy demonstrates encouraging antitumor activity in heavily pretreated pts who have progressed after CAR-T therapy, with a generally manageable safety profile. Durable CRs were achieved in this difficult-to-treat setting. These data support the potential role of odronextamab in the treatment paradigm for R/R DLBCL. Further studies to evaluate the optimal sequencing and combinations of odronextamab with CAR-T therapy are warranted.

Background: Rearranged during transfection ( RET ) alterations are targetable oncogenic drivers in thyroid cancer. Primary data from the open-label, phase 1/2 ARROW study demonstrated clinical activity and manageable safety with pralsetinib, a selective RET inhibitor, in patients with advanced/metastatic RET -altered thyroid cancer. We present an updated analysis with more patients and longer follow-up. Methods: Adult patients with advanced/metastatic RET -mutant medullary thyroid cancer (MTC) or RET fusion-positive thyroid cancer who initiated oral pralsetinib at 400 mg once daily were included. Primary endpoints were overall response rate (ORR) by blinded independent central review (per RECIST v1.1) and safety. Secondary endpoints included duration of response (DoR), progression-free survival (PFS), and overall survival. Responses were assessed in three cohorts of patients with baseline measurable disease: patients with RET -mutant MTC who had received prior cabozantinib and/or vandetanib (C/V), treatment-naïve patients with RET -mutant MTC, and patients with previously treated RET fusion-positive thyroid cancer. Patient-reported outcomes (PROs) were an exploratory endpoint. Results: As of October 18, 2021, the measurable disease population comprised of 61 patients with RET -mutant MTC and prior C/V, 62 treatment-naïve patients with RET -mutant MTC, and 22 patients with RET fusion-positive thyroid cancer who had received prior systemic therapy, including radioactive iodine. The ORR was 55.7% [confidence interval; 95% CI: 42.4–68.5] in patients with RET -mutant MTC and prior C/V, 77.4% [95% CI: 65.0–87.1] in treatment-naïve patients with RET -mutant MTC, and 90.9% [95% CI: 70.8–98.9] in patients with previously treated RET fusion-positive thyroid cancer. Median DoR and median PFS were both 25.8 months in patients with RET -mutant MTC and prior C/V, not reached in treatment-naïve patients with RET -mutant MTC, and 23.6 and 25.4 months, respectively, in patients with previously treated RET fusion-positive thyroid cancer. In the RET -altered thyroid cancer safety population ( N = 175), 97.1% of patients reported a treatment-related adverse event (TRAE); these led to discontinuation in 5.7% and dose reduction in 52.6% of patients. There was one death (0.6%) due to a TRAE. PROs improved or remained stable after pralsetinib treatment. Conclusions: In this updated analysis of the ARROW study, pralsetinib continued to show deep and durable clinical activity and a manageable safety profile in patients with advanced/metastatic RET- altered thyroid cancer.

Abstract Background Hospital-acquired and ventilator-associated pneumonia (HAP/VAP) remain significant causes of morbidity and mortality among patients admitted to a medical facility. Consensus guidelines for the treatment of HAP/VAP recommend patients with certain risk factors be empirically treated with an anti-methicillin resistant Staphylococcus aureus (MRSA) and anti-pseudomonal antibiotic. The most commonly utilized anti-pseudomonal agents at BJC hospitals include cefepime, followed by piperacillin/tazobactam and meropenem. The purpose of this study is to determine if there is a difference in clinical outcomes between cefepime and the other most commonly used anti-pseudomonal antibiotics, piperacillin/tazobactam or meropenem, at these institutions for the treatment of HAP/VAP. Methods This retrospective, multicenter cohort study included adult patients with HAP/VAP who received cefepime, meropenem, or piperacillin/tazobactam. Major exclusion criteria included patients that received antibiotics within 48 hours of hospital admission or less than 48 hours of empiric antibiotics. The primary outcome was in-hospital mortality. Secondary outcomes included change in initial antibiotic, mechanical ventilation-free days, ICU length of stay, hospital length of stay, hospital readmission, and new C. difficile infection. Results Of 1,117 included patients, 1,008 patients received cefepime and 109 received meropenem or piperacillin/tazobactam. Incidence of in-hospital mortality was not observed to be significantly different among empiric Gram-negative regimens (cefepime group 19.4% vs. meropenem or piperacillin/tazobactam 22%, p=0.521. Change in initial antibiotic, ICU length of stay, and hospital length of stay were observed to be significantly higher in the cefepime group. Conclusion We observed no difference in in-hospital mortality between cefepime and piperacillin/tazobactam or meropenem. However, there was a significantly higher incidence of change in initial antibiotic, ICU length of stay, and hospital length of stay observed in the cefepime group, though additional research is needed to corroborate these observations.

A history of hypertensive disorders of pregnancy, including preeclampsia, place women at an elevated risk of developing hypertension and cognitive impairments as they age. The purpose of this study was to determine if aortic hemodynamics were related to cognition in postmenopausal women with a history of hypertensive disorders of pregnancy. We evaluated 33 postmenopausal women with a history of preeclampsia (PE: age = 59 ± 5 y; BMI = 29 ± 5 kg/m 2 ; years since last pregnancy = 35 ± 3 y) and 29 postmenopausal women with a history of normotensive pregnancy (NTP: age = 59 ± 5 y; BMI = 26 ± 5 kg/m 2 ; years since last pregnancy = 35 ± 3 y). Participants underwent a cognitive testing battery including letter‐number sequencing, trail making test B, letter fluency, and category fluency tests to evaluate executive functioning and working memory. Mean arterial pressure (MAP) was measured with a brachial blood pressure cuff. Applanation tonometry (SphygmoCor) was used to derive the aortic pressure waveform and calculate aortic systolic blood pressure (ASBP), aortic diastolic blood pressure (ADBP), augmentation index (AI), and augmented pressure (AP). There were no differences in cognitive scores between groups (p > 0.05). Brachial blood pressure (MAP: 103 ± 2 vs. 103 ± 3 mmHg) and aortic hemodynamic measures (ASBP: 123 ± 3 vs. 121 ± 3 mmHg; ADBP: 78 ± 2 vs. 77 ± 2 mmHg; AI: 31 ± 2 vs. 28 ± 1 %; AP: 17 ± 1 vs. 15 ± 1 mmHg) were also similar between PE women and NTP women, respectively (p > 0.05 for all). There were no associations between measures of aortic hemodynamics and cognitive scores in women independent of their pregnancy history (p > 0.05). When evaluating these relationships within each group, ADBP was significantly associated with worse scores for letter‐number sequencing and letter fluency in PE women (r = −0.433 and r = −0.441, respectively, p < 0.05). Taken together, our results indicate aortic hemodynamic measures are not associated with cognition in middle‐aged postmenopausal women with different pregnancy histories; however, future studies should address the influence of elevated aortic hemodynamic variables and the longitudinal change in cognitive function in postmenopausal women with different pregnancy histories.

Background The risk of hypertension increases as women reach menopause. Our group has recently reported that autonomic support of blood pressure (BP) is increased in post‐menopausal women. Given regular exercise is known to decrease the risk of developing hypertension, we investigated the role of aerobic fitness on autonomic support of BP in women. We hypothesized that trained premenopausal, but not postmenopausal, women would have less autonomic support of BP than age‐matched untrained women. Methods Twelve healthy, young premenopausal (27±1yrs) and 10 older postmenopausal (56±1yrs) women completed VO 2max tests on cycle ergometers. The participants were then stratified by fitness level based on VO 2max percentiles from the American College of Sports Medicine's Guidelines (≤50 th percentile = untrained; >50 th percentile = trained; premenopausal: 7 untrained, 5 trained; postmenopausal: 5 untrained, 5 trained). On a separate day muscle sympathetic nerve activity (MSNA, microneurography, peroneal nerve), heart rate (electrocardiography), and blood pressure (brachial arterial catheter) were recorded before and during ganglionic blockade using trimethaphan camsylate (dose:1.5–7mg/min). Stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) were calculated from the blood pressure waveform (WinCPRS). Results Muscle sympathetic nerve activity was higher in trained young women than in untrained young women (burst incidence: 35±11 vs. 12±2 bursts/100 heart beats, p=0.03). Young trained women had a smaller reduction in mean arterial pressure (MAP) with trimethaphan than young untrained women (ΔMAP:−5±3 vs. −15±4mmHg, p=0.01), despite a larger reduction in total peripheral resistance (ΔTPR: −6±1 vs. −2±1mmHg*min/L, p=0.02). The trained young women were able to maintain their MAP due to a greater increase in cardiac output (ΔCO: 1.4±0.4 vs. −0.3±0.3L/min, p= 0.01). In older postmenopausal women, MSNA and the fall in BP, CO, and TPR with trimethaphan were not different between trained and untrained individuals (p= 0.81, 0.16, 0.52 and 0.09, respectively). Conclusion Baseline MSNA was higher in trained premenopausal women when compared to untrained premenopausal women; however, aerobic fitness did not influence baseline MSNA in postmenopausal women. In young trained women, the fall in MAP following ganglionic blockade was only one‐third of the response seen in young untrained women. Baseline MSNA and the change in MAP, CO, and TPR with ganglionic blockade were not different between trained and untrained postmenopausal women. These data suggest aerobic fitness reduces autonomic support of blood pressure in young trained women, but not in trained postmenopausal women.

Purpose Obese adults exhibit increased levels of inflammation which may negatively affect blood pressure regulation. Based on existing literature, we hypothesized: 1) baroreflex sensitivity would be lower in obese adults when compared to lean adults and 2) acute ibuprofen (IBU, a cyclooxygenase inhibitor and nonsteroidal anti‐inflammatory agent) administration would increase baroreflex sensitivity in obese adults, with no effect in lean adults. Methods Seven lean (4M, 3F; 25±2 yrs; 23±1 kg/m 2 ) and six obese (5M, 1F; 30±3 yrs; 36±1 kg/m 2 ) adults completed two visits randomized to control (CON) or IBU (800 mg oral). On each visit, blood pressure (intra‐arterial catheter), heart rate (electrocardiogram), and muscle sympathetic nerve activity (MSNA, microneurography) were measured continuously and venous blood was sampled for measures of systemic inflammation [C‐Reactive protein (CRP) and Interleukin‐6 (IL‐6)]. Sympathetic and cardiac baroreflex sensitivity were assessed using the modified Oxford technique, which consisted of a 5‐min resting period, followed by a 100 μg intravenous bolus of sodium nitroprusside. One minute later, subjects were administered a 150 μg intravenous bolus of phenylephrine HCl and data were collected for an additional 2‐min. Results CRP and IL‐6 were higher in obese adults when compared to lean adults, and tended to decrease with IBU (IL‐6: p<0.05; CRP: p=0.14). Cardiac baroreflex sensitivity was lower in obese adults (14±2 vs 24±2 ms/mmHg, p=0.02), whereas sympathetic baroreflex sensitivity was higher in obese adults (−3.6±0.5 vs −2.1±0.5 bursts/100 beats/mmHg, p=0.03) when compared to lean. There was no effect of IBU on cardiac or sympathetic baroreflex sensitivity in either group (p‐value range 0.20 – 0.71). Conclusion In our present group of relatively healthy individuals with obesity, we observed lower cardiovagal baroreflex sensitivity but higher sympathetic baroreflex sensitivity in the obese group compared to lean controls. We found no effect of an acute dose of 800 mg ibuprofen on cardiac or sympathetic baroreflex sensitivity, suggesting that chronic effects of obesity‐related inflammation on baroreflex sensitivity may not be reversed by a single acute pharmacological anti‐inflammatory intervention.
