Abstract Introduction AD109, an investigational oral anti-apneic neuromuscular modulator, combines in one tablet the novel antimuscarinic, aroxybutynin (2.5 mg), with the selective norepinephrine reuptake inhibitor, atomoxetine (75 mg). AD109 significantly improved the apnea-hypopnea index and oxygenation vs placebo (PBO) in two phase 3 clinical trials in OSA. This exploratory analysis evaluated concomitant administration of AD109 with glucagon-like peptide-1 receptor agonists (GLP-1 RA) on weight change in OSA. Methods SynAIRgy (NCT05813275; N=646) and LunAIRo (NCT05811247; N=660) were randomized, double-blinded, PBO-controlled, parallel-arm phase 3 trials of AD109 vs PBO in adults with mild-to-severe OSA (AHI >5) who failed or refused positive airway pressure therapy. Participants must have had a body mass index (BMI) 18.5–40 kg/m2 for males / 18.5–42 kg/m2 for females. Participants receiving GLP-1 RA for diabetes were permitted. Body weight was assessed throughout the trials. Results One-hundred and six participants were enrolled in the phase 3 trials taking a GLP-1 RA for diabetes (PBO+GLP-1 RA: n=48; AD109+GLP-1 RA: n=58). In participants receiving a GLP-1 RA with baseline BMI < 30, AD109 reduced weight by 2.7% (vs PBO: -1.4%, P=0.08) and 0.5% (vs PBO: 2.3%, P=0.60) at Week 26 and Week 51, respectively. In participants receiving a GLP-1 RA with baseline BMI 30 to 34.9, AD109 reduced weight by 0.9% (vs PBO: 1.2%, P=0.84) and 2.5% (vs PBO: 3.3%, P=0.85) at Week 26 and Week 51, respectively. In participants receiving a GLP-1 RA with baseline BMI ≥35, AD109 reduced weight by 5.5% (vs PBO: 0.9%, P=0.02) and 11.5% (vs PBO: 3.8%, P=0.04) at Week 26 and Week 51, respectively. Participants not receiving GLP-1 RA (n=979) showed smaller weight reductions across BMI classes; in participants with BMI ≥35, AD109 reduced weight by 1.4% (vs PBO: 0.2%, P=0.002) and 2.8% (vs PBO: 1.4%, P=0.19) at Week 26 and Week 51, respectively. Conclusion In this exploratory analysis using pooled data from SynAIRgy and LunAIRo, results indicate that participants with a baseline BMI ≥35 receiving AD109+GLP-1 RA experienced progressively greater weight loss over time relative to GLP-1 RA alone. Future studies are needed to further evaluate concomitant administration of AD109+GLP-1 RA in OSA. Support (if any) These studies were supported by Apnimed, Inc.
Disparities During Family-Centered Rounds for Families Using Languages Other Than English
BACKGROUND/OBJECTIVE Patient- and family-centered rounds (PFCR) have become a pediatric standard of care. However, rounds experiences of families using languages other than English (LOE)—particularly languages other than English or Spanish (LOES; eg, Arabic)—receive less focus. We aimed to identify differences in PFCR communication and engagement by language. METHODS We analyzed postintervention data from a 21-center structured PFCR study, assessing communication practices, quality, and family and nurse engagement during PFCR. Logistic regression adjusted by site compared PFCR between families using (1) LOE vs English, (2) Spanish vs English, and (3) LOES vs English. RESULTS Among 3051 PFCR encounters, 348 (11.4%) involved LOE (Spanish = 260; LOES = 85). Interpretation was not used in 7.2%, 5.8%, and 9.4% of encounters using LOE, Spanish, and LOES, respectively. PFCR in the following groups had lower adjusted odds (adjusted odds ratio [95% CI]) for the following domains: (1) LOE vs English: including providing verbal patient summaries (0.66 [0.46–0.95]), explaining diagnoses and differentials (0.62 [0.44–0.88]), family engagement (0.34 [0.20–0.57]), nursing inclusion (0.75 [0.60–0.93]), and nursing engagement (0.69 [0.52–0.90]). (2) Spanish vs English: diagnoses/differentials being explained (0.56 [0.37–0.85]), family engagement (0.35 [0.18–0.67]), nursing inclusion (0.77 [0.59–1.00]), and nursing engagement (0.68 [0.52–0.89]). (3) LOES vs English: families sharing concerns (0.66 [0.47–0.93]), family engagement (0.30 [0.16–0.54]), and nursing inclusion (0.74 [0.55–0.99]). CONCLUSION Even after implementing a PFCR intervention, families using LOE—especially LOES—experienced significant disparities in communication and engagement. Future approaches to improving PFCR should emphasize language access and promote nurse and family engagement for families using LOE, particularly LOES.
The Angiography Pattern of Buerger’s Disease: Challenges and Recommendations
In 2023, the VAS international working group on Buerger’s Disease (BD) recommended two diagnostic criteria based on a prior Delphi study: “definitive” and “suspected”. The “definitive” criteria are history of smoking, typical angiography, and typical histopathological features. All three features are mandatory to confirm a “definitive” diagnosis of BD. The conundrum is—what features should be considered typical of BD angiography? According to this review, segmental occlusion of infrapopliteal arteries, corkscrew collaterals that appear to continue the occluded arterial segment (Martorell’s sign) or bypass the segmental occlusion, absence of atherosclerotic plaque or aneurysm could differentiate BD from ASO. Hence, for “typical” BD angiography, these manifestations should certainly be considered. However, data for differentiating angiography patterns of BD from the small- and medium-sized vasculitis including Behcet’s disease, scleroderma, hepatitis associated vasculitis, and anti-phospholipid syndrome are limited. Further studies for investigating the angiography pattern in BD patients in early and late presentation of BD, particularly in the patients with long-term follow up, are highly recommended.
Making a difference: 5 years of Cardiac Surgery Intersociety Alliance (CSIA)
Informed by the almost unimaginable unmet need for cardiac surgery in the developing regions of the world, leading surgeons, cardiologists, editors in chief of the major cardiothoracic journals as well as representatives of medical industry and government convened in December 2017 to address this unacceptable disparity in access to care. The ensuing “Cape Town Declaration” constituted a clarion call to cardiac surgical societies to jointly advocate the strengthening of sustainable, local cardiac surgical capacity in the developing world. The Cardiac Surgery Intersociety Alliance (CSIA) was thus created, comprising The Society of Thoracic Surgeons (STS), the American Association for Thoracic Surgery (AATS), the Asian Society for Cardiovascular and Thoracic Surgery (ASCVTS), the European Association for Cardio-Thoracic Surgery (EACTS) and the World Heart Federation (WHF). The guiding principle was advocacy for sustainable cardiac surgical capacity in low-income countries.

The guiding principle was advocacy for sustainable cardiac surgical capacity in low-income countries. As a first step, a global needs assessment confirmed rheumatic heart disease as the overwhelming pathology requiring cardiac surgery in these regions. Subsequently, CSIA published a request for proposals to support fledgling programmes that could demonstrate the backing by their governments and health care institution. Out of 11 applicants, and following an evaluation of the sites, including site visits to the 3 finalists, Mozambique and Rwanda were selected as the first Pilot Sites. Subsequently, a mentorship and training agreement was completed between Mozambique and the University of Cape Town, a middle-income country with a comparable burden of rheumatic heart disease. The agreement entails regular video calls between the heart teams, targeted training across all aspects of cardiac surgery, as well as on-site presence of mentoring teams for complex cases with the strict observance of ‘assisting only’. In Rwanda, Team Heart, a US and Rwanda-based non-governmental organization (NGO) that has been performing cardiac surgery in Rwanda and helping to train the cardiac surgery workforce since 2008, has agreed to continue providing mentorship for the local team and to assist in the establishment of independent cardiac surgery with all that entails. This involves intermittent virtual conferences between Rwandan and US cardiologists for surgical case selection. Five years after CSIA was founded, it’s ‘Seal of Approval’ for the sustainability of endorsed programmes in Mozambique and Rwanda has resulted in higher case numbers, a stronger government commitment, significant upgrades of infrastructure, the nurturing of generous consumable donations by industry and the commencement of negotiations with global donors for major grants. Extending the CSIA Seal to additional deserving programmes could further align the international cardiac surgical community with the principle of local cardiac surgery capacity-building in developing countries.

Vascular Diseases in Women: Do Women Suffer from Them Differently?
According to the World Health Organization, cardiovascular disease (CVD) is the leading cause of death among women worldwide, yet its magnitude is often underestimated. Biological and gender differences affect health, diagnosis, and healthcare in numerous ways. The lack of sex and gender awareness in health research and healthcare is an ongoing issue that affects not only research but also treatment and outcomes. The importance of recognizing the impacts of both sex and gender on health and of knowing the differences between the two in healthcare is beginning to gain ground. There is more appreciation of the roles that biological differences (sex) and sociocultural power structures (gender) have, and both sex and gender affect health behavior, the development of diseases, their diagnosis, management, and the long-term effects of an illness. An important issue is the knowledge and awareness of women about vascular diseases. The risk of cardiovascular events is drastically underestimated by women themselves, as well as by those around them. The purpose of this review is to draw attention to improving the medical care and treatment of women with vascular diseases.
Potential interaction between exogenous anabolic steroids and sugammadex: failed reversal of rocuronium in a patient taking testosterone and trestolone acetate
AbstractPulmonary arterial hypertension (PAH) is a progressive, devastating disease, and its main histological manifestation is an occlusive pulmonary arteriopathy. One important functional component of PAH is aberrant endothelial cell (EC) function including apoptosis‐resistance, unchecked proliferation, and impaired migration. The mechanisms leading to and maintaining physiologic and aberrant EC function are not fully understood. Here, we tested the hypothesis that in PAH, ECs have increased expression of the transmembrane protein integrin‐β5, which contributes to migration and survival under physiologic and pathological conditions, but also to endothelial‐to‐mesenchymal transition (EnMT). We found that elevated integrin‐β5 expression in pulmonary artery lesions and lung tissue from PAH patients and rats with PH induced by chronic hypoxia and injection of CD117+ rat lung EC clones. These EC clones exhibited elevated expression of integrin‐β5 and its heterodimerization partner integrin‐αν and showed accelerated barrier formation. Inhibition of integrin‐ανβ5 in vitro partially blocked transforming growth factor (TGF)‐β1‐induced EnMT gene expression in rat lung control ECs and less in rat lung EC clones and human lung microvascular ECs. Inhibition of integrin‐ανβ5 promoted endothelial dysfunction as shown by reduced migration in a scratch assay and increased apoptosis in synergism with TGF‐β1. In vivo, blocking of integrin‐ανβ5 exaggerated PH induced by chronic hypoxia and CD117+ EC clones in rats. In summary, we found a role for integrin‐ανβ5 in lung endothelial survival and migration, but also a partial contribution to TGF‐β1‐induced EnMT gene expression. Our results suggest that integrin‐ανβ5 is required for physiologic function of ECs and lung vascular homeostasis.
Abstract 3820: Penumbra Imaging Collaborative Study (PICS): Utilization of Imaging for Patient Selection and Its Impact on Outcomes Following Penumbra System
®
Treatment
Purpose: Various imaging approaches are utilized for evaluating acute stroke patients. Despite numerous studies, there is no clear evidence that one approach is superior to another for identifying which patients will benefit from mechanical thrombectomy (MT). The PICS registry was established to determine the imaging modalities being employed to triage acute stroke patients for MT and to assess their impact on patient functional outcome. Methods: Patients were enrolled across 35 centers. For each patient, the baseline imaging modality was recorded to determine the utilization rates of noncontrast CT (NCCT), CT perfusion (CT-P), and MRI diffusion weighted imaging (DWI). All patients subsequently treated by the Penumbra System per standard of care were followed for 3 months after the procedure to assess functional outcome using the modified Rankin Scale (mRS). Results: A total of 305 patients were enrolled in this registry, of which 267 had the requisite imaging modalities used for this analysis. Of these, 49.4% were females. Mean age was 66.6 ± 15.9 years; median NIHSS score was 17.0 (IQR 12-21). The median time from stroke onset to presentation was 2.3 hours, from stroke symptom onset to arterial puncture was 4.8 hours, and from arterial puncture to end of thromboaspiration was 73.0 minutes. Post-treatment evaluation revealed that 83.5% of patients were successfully recanalized to TIMI 2/3 (from TIMI 0/1) with 43.5% achieving a 90-day mRS of 0-2. All cause mortality was 19.9% with symptomatic intracranial hemorrhage reported in 4.5% of the patients. The principal imaging modalities used for patient triage were NCCT in 61.8%, CT-P in 27.3% and DWI in 10.9% of the study population. Of the patients selected for NCCT, 42.5% were functionally independent at 90 days, whereas for CT-P and DWI, the rates were 45.9% and 42.9%, respectively. There was no significant difference between groups for patient age, baseline NIHSS, time from onset to presentation, time from arterial puncture to end of thromboaspiration. The time from stroke symptom onset to groin puncture was significantly different in the DWI cohort (p<0.0001) with a median of 4.4 hrs for NCCT, 4.8 hrs for CTP, and 6.5 hrs for DWI. There was a significant difference in % of female patients with CTP 37.0%, DWI 48.3%, and NCCT 55.2% (p=0.034). Conclusion: The type of imaging modality utilized to triage acute ischemic stroke patients for MT varies widely across the US. Based on the present findings, the imaging approach appears to have little impact on patient functional outcome after MT.
