We would like to highlight four points regarding recent EBMT recommendations for the use of chimeric antigen receptor (CAR) T cells in autoimmune diseases.1 First, the recommendations are based on conventional, integrating vector-based CAR-Ts, which require lymphodepletion chemotherapy, inpatient administration and prolonged post-infusion monitoring. In phase 1/2 trials in generalized myasthenia gravis, mRNA CAR-Ts were administered outpatient, without lymphodepletion, and resulted in no cytokine release syndrome or neurotoxicity.

Background and objectives
Violence against women (VAW) is widespread and can have serious physical and mental health consequences, including post-traumatic stress disorder (PTSD) and sleep disorders. Victim-survivors often face barriers in accessing specialised care, highlighting the need for a multidisciplinary response, especially in healthcare settings. The Maison des Femmes (MdF) model provides holistic support to women experiencing VAW, including medical, psychological, social and legal support. The aim of this study is to examine whether the MdF’s comprehensive intervention programme offers advantages over standard care in improving mental health indicators, such as PTSD.

Method and analysis
Our pragmatic quasi-experimental study uses a non-randomised controlled cluster design. The intervention group comprises women enrolled in MdFs in five French cities, while the comparison group includes women receiving usual care in sociomedical structures located geographically close to MdF centres. Our study aims to recruit 360 women (180 per group), aged 18 years or older, who have experienced intimate partner violence or sexual violence and who seek care at the study centres. The primary analysis will compare the change in PTSD Checklist for DSM-5 (PCL-5) scores over 6 months in the two groups using multivariable linear regression with propensity score adjustment. Secondary outcomes include sleep disorders, quality of life, symptoms of anxiety and depression, self-esteem, sense of safety and well-being, initiation of legal and socioprofessional proceedings, and healthcare utilisation.

Circulation, Volume 150, Issue Suppl_1, Page A4134309-A4134309, November 12, 2024. Introduction:We report the case of a heart transplant patient on chronic immunosuppression diagnosed with cryptococcal meningitis. Up to 5% of solid organ transplant patients develop cryptococcosis, carrying a 50% mortality rate in central nervous system involvement.Case Presentation:This is a 57-year-old male with a past medical history of heart failure with reduced ejection fraction (HFrEF) status post orthotopic heart transplantation (on prednisone 7.5 mg daily, mycophenolate, tacrolimus and sirolimus), pulmonary sarcoid, and chronic hepatitis B (on tenofovir and entecavir) who presented with headache, nausea, vomiting and seizure-like activity. The patient’s heart rate was 129 beats per minute, blood pressure 188/92 mmHg, but was afebrile. He eventually underwent a lumbar puncture with the cerebrospinal fluid (CSF) positive for cryptococcal antigen (1:2560). The patient was started on liposomal amphotericin B and flucytosine. Mycophenolate and sirolimus were held in the setting of his infection. The patient’s hospital course was complicated by acute kidney injury likely secondary to elevated tacrolimus levels while on fluconazole. He was ultimately discharged with plans to repeat CSF studies as an outpatient.Discussion:Here we report a case of cryptococcal meningitis in a heart transplant patient in the context of pulmonary sarcoidosis, chronic hepatitis B and quadruple immunosuppression. Of note, as part of rejection surveillance, the patient undertook serial AlloSure and AlloMap testing. Sirolimus was added to his regimen due to persistently elevated AlloSure scores. Indeed, immunosuppressive agents are the leading risk factor for cryptococcosis in organ transplant patients. Our patient also has two important risk factors for cryptococcal infection. Firstly, sarcoidosis is associated with T-cell dysregulation, compromising cell-mediated immunity. Additionally, hepatitis B carriers have an increased predisposition for cryptococcal infections, notwithstanding that our patient had been on dual antiviral therapy.Conclusion:Quadruple immunosuppression in heart transplant patients, especially in the context of risk factors such as sarcoidosis and hepatitis B infection, can result in cryptococcal meningitis and should be considered in patients with suggestive symptoms. Effective prophylactic regimens for such higher risk patients may be a potential area for further investigation.

Circulation, Volume 150, Issue Suppl_1, Page ASa308-ASa308, November 12, 2024. Background:Active compression-decompression (ACD) cardiopulmonary resuscitation (CPR), an impedance threshold device (ITD) and controlled, gradual, automated head and thorax elevation, collectively termed automated Head Up Position (AHUP) CPR, increases cerebral perfusion pressure (CerPP), brain blood flow, coronary perfusion pressure (CorPP), end tidal CO2 (ETCO2) and cerebral oximetry (rSO2) in animal models when compared with conventional (C) CPR. AHUP-CPR in patients is associated with increased neurologically favorable survival versus C-CPR. This study tested the hypothesis that AHUP CPR will increase cardiac stroke volume (SV) and other hemodynamics compared with C-CPR in a porcine model of cardiac arrest.Methods:Farm pigs (n=15) were sedated, anesthetized, and ventilated. Hemodynamics, including intracardiac conductance catheter based biventricular (BiV) pressure-volume (PV) loops, were continuously measured and recorded. After 10 minutes of untreated ventricular fibrillation, C-CPR was performed for 2 minutes in the supine position using an automated CPR device designed for pigs at a rate of 100 compressions/minute, depth of 21% of the chest antero-postero diameter, a 50% duty cycle, and no active decompression. ACD+ITD was then performed with 3 cm of active decompression for 2 minutes, followed by AHUP-CPR, where the head and thorax were initially raised to 10 cm and 8 cm for a 2-minute priming phase, followed by elevation over the next 2 minutes to 24 cm and 9 cm. A linear mixed-effects model with a random intercept for individual pigs was used for statistical analysis.Results:CerPP, CorPP, ETCO2, and rSO2, as well as BiV SV and cardiac output, increased progressively and significantly with implementation of AHUP-CPR (p

Circulation, Volume 150, Issue Suppl_1, Page A4122486-A4122486, November 12, 2024. Background:Fetal cardiomyopathy (FCM) affects 8 per 100,000 live births, often with unknown etiology. Progress in fetal cardiac screening, genetic testing and management may have impacted historically poor outcomes.Aims:We sought to investigate genetic associations and clinical outcomes of FCM in the current era.Methods:This was a retrospective Fetal Heart Society Research Collaborative cohort study of FCM cases diagnosed from January 2017-December 2021 in 39 centers. Cases of fetal myocardial disease attributable to maternal diabetes, structural heart disease, arrhythmia or extra-cardiac conditions were excluded. Data including outcomes to 1 year after birth were collected. Significance of genetic testing results and FCM subtype were classified by each center.Results:There were 138 FCM cases diagnosed at a median gestational age of 27+4weeks (range 13-39 weeks). Suspected fetal heart disease (41%, 56/138) was the most common referral indication. There was a known family history of CM in 19% (26/138). FCM phenotypes included 38% (52/138) dilated, 24% (33/138) hypertrophic, 17% (24/138) non-compacted, 10% (14/138) mixed, 5% (7/138) restrictive, 3% (4/138) ventricular aneurysm, 3% (4/138) unspecified. Hydrops was present at diagnosis in 15% (20/138) and by delivery or at fetal demise in 26% (36/138). Of 128 continued pregnancies, 7% (9/128) had a fetal demise, 92% (118/128) a live birth and one was lost to follow-up. Among live births, 10% (12/118) received only palliative care. Of 106 actively treated, 75% (80/106) survived to 1 year; 7% (7/106) required ECMO, and 22% (23/106) were listed for transplant with 18 of these successfully transplanted. Of the cohort, a total of 80% (110/138) had genetic testing (including 30 with invasive prenatal testing), with 38% (52/138) having a confirmed genetic etiology and 28% (38/138) with a variant of uncertain significance (VUS) (Figure 1). Transplant-free survival to 1 year was similar for those with and without a genetic diagnosis (40%,21/52 vs 47%,40/86, p=0.48).Conclusion:Outcomes remain poor in FCM, with

Circulation, Volume 150, Issue Suppl_1, Page A4142044-A4142044, November 12, 2024. Background:Myocarditis is a dreaded complication of immune-checkpoint inhibitor (ICI) therapy but challenging to diagnose. There are no published data comparing the two leading diagnostic criteria for ICI myocarditis and their association with cardiovascular events.Methods:Patients treated with ICI and cardiac Troponin (cTnT) measurements thereafter at a tertiary institution from 2011 to 2022 were identified. Charts were reviewed for ICI-related myocarditis according to the Bonaca et. al criteria and the ESC-ICOS guideline criteria. A propensity matched control group was identified of patients treated with ICI but without developing myocarditis. Medical records were reviewed for baseline characteristics and long-term outcomes, including cardiac death, MACE (myocardial infarction, TIA/stroke, new heart failure diagnosis), and arrhythmias (V-tach, A-fib, complete heart block).Results:A total of 59 patients were identified as having a diagnosis of ICI-related myocarditis per Bonaca criteria (16 having definite, 13 probable and 30 possible myocarditis), and 47 met the ESC-ICOS guideline criteria. Mean age was 73.1±10.2 years, 60.1% were male, median follow-up was 2.5 years. ICI-related myocarditis as diagnosed by both diagnostic criteria had prognostic value for cardiac death (HR 13.94, 95%CI 1.84-105.64, p=0.011 per Bonaca, HR 6.22, 95%CI 1.77-21.88, p=0.004 per ESC-ICOS), MACE, (HR 3.17, 95%CI 1.34-7.47, p=0.008 per Bonaca, HR 2.97, 95%CI 1.37-6.45, p=0.006 per ESC-ICOS), and arrhythmias (HR 1.93, 95%CI 1.10-3.38, p=0.022 per Bonaca, HR 2.09, 95%CI 1.21-3.60, p

Circulation, Volume 150, Issue Suppl_1, Page A4141628-A4141628, November 12, 2024. Introduction:Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of mortality worldwide. Lipid-lowering therapies (LLTs) are a key element to reduce the risk of recurrence of ASCVD events. However, despite concordant guidelines, LLTs are often underused in real-life setting.Research questions:The aim of this study is to describe the use of LLTs and its impact on morbi-mortality in the year following a first ASCVD event.Methods:This retrospective study used the national health data system (SNDS), collecting health insurance claims and hospital discharge data from 99% of the French population. Incident cases in 2021 were identified, corresponding to all adults with a first ASCVD event, based on ICD-10 hospital coding. ASCVD includes coronary artery disease [myocardial infarction, unstable angina or coronary revascularization], cerebrovascular events [ischemic stroke, carotid revascularization] and peripheral artery disease (PAD) requiring artery revascularization. In patients discharged alive from the index event, longitudinal analyses were performed at 1-year from discharge to describe LLT use, occurrence of major ASCVD events and all-cause mortality.Results:In 2021, 195,211 newly diagnosed ASCVD cases were identified among 43,1M adults (mean age: 70.3 (±13.7) yo; 62% of male). The first ASCVD event was myocardial infarction (N=51,614) or ischemic stroke (N=52,865) in 53.5% of incident cases. The remaining 46.5% corresponded mostly to coronary revascularization procedures (N=83,910), followed by PAD (N=26,925). In-hospital mortality was 5.5% (N=10,673). In patients analyzed at 1 year (N=180,875), 16.9% did not receive any LLT. This value rose to 26.7% among patients who had no received LLT prior to the ASCVD event. After a myocardial infarction, patients were more likely to receive LLT (91.9%) compared to after an ischemic stroke (72.9%) or revascularization for PAD (68.0%). Finally, 1-year all-cause mortality was higher in non-LLT compared to LLT patients (20.9% vs 4.0%). Additional data on the recurrence of ASCVD events as a function of LLT use are currently being analyzed and will be presented at the congress.Conclusion:Contrary to recommendations, the underuse of LLTs after a first ASCVD event remains very high, particularly after a stroke. This is associated with a significantly higher mortality at 1 year, justifying the need to reinforce implementation of the guidelines in real life for a better management of residual lipid risk.

Circulation, Volume 150, Issue Suppl_1, Page A4138483-A4138483, November 12, 2024. Background:Hypoplastic left heart syndrome (HLHS) is classified by subtype: mitral atresia and aortic atresia (MA-AA), mitral stenosis and aortic atresia (MS-AA), and mitral stenosis and aortic stenosis (MS-AS). It is controversial whether specific HLHS subtypes and presence of ventriculocoronary connections (VCC) are associated with transplant-free survival. We aimed to determine whether there is an increased risk of mortality associated with specific HLHS subtypes, whether this risk is stratified by the presence of VCC, and if a specific type of stage I palliation in patients with VCC improves survival. We also aimed to determine practice variation in the evaluation of HLHS patients with VCC.Methods:We performed a multicenter retrospective cohort study of fetuses and infants < 2 months of age with HLHS admitted between 1/2012-12/2016 to participating Fetal Heart Society institutions. Patients with HLHS variants were excluded. We collected patient specific data and surveyed participating centers for practice variation. Kaplan-Meier curves with log-rank test were used to assess transplant-free survival and cox proportional hazard analysis was performed with adjustment for center as a random intercept.Results:341 patients from nine centers were included. MA-AA was the most common subtype (177, 52%), followed by MS-AA (102, 30%), and MS-AS (62, 18%). VCC were diagnosed or suspected in 65 patients (19%). A total of 287 patients were live born with intention to treat. HLHS subtype was not associated with transplant-free survival (Figure 1A). Presence of VCC was associated with a lower transplant-free survival (p=0.026, Figure 1B). In the subset of patients diagnosed with VCC, there was not a significant difference in survival based on type of stage I palliation (Figure 1C). Cox proportional hazard modeling adjusted for center demonstrates that presence of VCC has a hazard ratio of 1.74 (CI 1.02-2.98), p =0.04. Survey data regarding practice variation for patients with VCC (Figure 2) demonstrates 33% of centers modify the type of stage I palliation based on presence of VCC.Conclusions:In a multicenter cohort of HLHS patients, patients with VCC had lower transplant-free survival compared to those without VCC, while subtype and type of stage I palliation did not have a statistical difference. There is considerable practice variation in the management of HLHS patients with VCC that may warrant further investigation.

Circulation, Volume 150, Issue Suppl_1, Page AOr108-AOr108, November 12, 2024. Background:Addition of resuscitative endovascular balloon occlusion of the aorta (REBOA) to automated head-up position (AHUP) cardiopulmonary resuscitation (CPR), the combination of active compression decompression CPR, an impedance threshold device, and controlled gradual elevation of the head and thorax, increases cerebral perfusion pressure. Optimal management of REBOA deflation after prolonged AHUP-CPR and ROSC is unknown.Hypothesis:We hypothesized that partial deflation of REBOA, rather than full deflation after ROSC, would result in better hemodynamic parameters.Aims:To compare hemodynamic parameters 1 minute before and 1 minute after complete (100%) versus partial (50%) REBOA deflation after prolonged AHUP-CPR and ROSC.Methods:Yorkshire pigs weighing ∼40 kg were anesthetized and ventilated. After 10 minutes of untreated ventricular fibrillation, AHUP-CPR was started and continued for a median time of 44 minutes. After ROSC, REBOA deflation was initiated in two ways: complete (100%) or partial (50%) deflation over 5 seconds. The following hemodynamic parameters were measured 1 minute before and 1 minute after deflation: mean aortic pressure (MAP), cerebral perfusion pressure (CerPP), and coronary perfusion pressure (CorPP). Data, in mmHg, are presented as mean ± SD, and compared using a paired t-test.Results:13 pigs were included, with 8 pigs in the 100% deflation group and 5 in the 50% deflation group. After ROSC in the 100% deflation group, MAP was 81.5±36.0 before deflation vs. 43.0±14.4 after (p=0.01), whereas in the 50% deflation group, MAP was 90.5±33.0 vs. 83.4±33.3 (p=0.02). CerPP was 72.3±34.4 before deflation vs. 35.9±14.6 (p=0.01) in the 100% deflation group, and 84.6±31.2 vs. 77.6±31.8 (p=0.02) with 50% deflation. Similarly, CorPP was 74.1±37.3 before deflation vs. 36.1±15.8 (p=0.01) after in the 100% deflation group, and 83.0±32.7 vs. 76.1±33.0 (p=0.02) in the 50% deflation group. The differences from before to after deflation were markedly less in the 50% deflation group versus the 100% deflation group: MAP (7.0±4.3 vs. 38.5±25.7, p=0.02), CerPP (7.1±4.4 vs. 36.3±24.4, p=0.02), and CorPP (6.0±4.2 vs. 39.8±25.2, p=0.02), respectively.Conclusion:In this porcine model of prolonged cardiac arrest, partial deflation of the REBOA balloon post ROSC resulted in strikingly higher hemodynamics compared with complete deflation. These findings highlight the need to develop a post-ROSC REBOA deflation strategy when used during AHUP-CPR.

Introduction
Buprenorphine is a highly effective treatment for opioid use disorder (OUD). However, provider observations and preliminary research suggest that the current standard maintenance dose may be insufficient for suppressing withdrawal and preventing cravings among people who use or have used fentanyl. Buprenorphine dosing guidelines were based on studies among people who use heroin and have not been formally re-evaluated since fentanyl became predominant in the unregulated drug supply. We aim to compare the effectiveness of a high (24 mg) vs standard (16 mg) maintenance daily dose of buprenorphine for improving retention in treatment, decreasing the use of non-prescribed opioids, preventing cravings and reducing opioid overdose risk in patients.

Methods and analysis
Adults who are initiating or continuing buprenorphine for moderate to severe OUD and have a recent history of fentanyl use (n=250) will be recruited at four outpatient substance use treatment clinics in Rhode Island. Patients continuing buprenorphine must be on doses of 16 mg or less and have ongoing fentanyl use to be eligible. Participants will be randomly assigned 1:1 to receive either a high (24 mg) or standard (16 mg) maintenance daily dose, each with usual care, and followed for 12 months to evaluate outcomes. Providers will determine the buprenorphine initiation strategy, with the requirement that participants reach the study maintenance dose within 7 days of randomisation. Providers may adjust the maintenance dose, if clinically needed, for participant safety. The primary study outcome is retention in buprenorphine treatment at 6 months postrandomisation, measured using clinical and statewide administrative data. Other outcomes include non-prescribed opioid use and opioid cravings (secondary), as well as non-fatal or fatal opioid overdose (exploratory).

Introduction
As the usage of online platforms becomes increasingly prevalent to share information, it is essential to garner a better understanding of the content disseminated across the internet. Studies have found that patients are relying on online resources to gather medical information, potentially encountering misinformation. The sharing of information concerning primary headaches, despite affecting a large portion of the world’s population, has not been comprehensively analysed through the lens of online content. This scoping review seeks to explore the extent of available information, uncover existing gaps in knowledge, and to serve as a resource for healthcare providers to educate themselves to provide informed care to patients.

Methods and analysis
Studies considered for inclusion are those focused on primary headache (including migraines, tension headaches and cluster headaches) content posted on a community platform. Any online community forum will be eligible, including but not limited to TikTok, Twitter, Facebook, YouTube, Instagram, online forums and blogs. Studies will be limited to those published in English, with no geographic restriction. Five electronic databases, namely PubMed, Cochrane Library, Scopus, EMBASE, PsycInfo, will be searched for published reports. Two reviewers will independently screen titles and abstracts. The reviewers will then assess the full texts selected. In both cases, disagreements will be discussed with a third reviewer and consensus will be achieved. Data analysis will be descriptive with a narrative summary.

Ethics and dissemination
Since this is a scoping review of previously published summary data, ethical approval for this study is not needed. Findings will be published in a peer-reviewed journal.
