Background: Sexual dimorphism in the facial skeleton is fundamental to aesthetics and gender perception. This study employs AI-assisted three-dimensional (3D) imaging to analyze morphological differences between males and females in the upper, mid, and lower facial regions. Methods: A retrospective analysis was conducted on 280 high-resolution craniofacial CT scans (147 females, 133 males) of adults aged 20 years and older. AI-assisted segmentation and modeling were performed using Materialise Mimics and 3-Matic software. The facial skeleton was divided into upper, mid, and lower regions for detailed morphometric evaluation. Statistical shape modeling (SSM) and heatmaps were used to visualize surface projection differences across age groups. Statistical comparisons were conducted to assess gender-based variation. Results: Significant sexual dimorphism was observed across all facial regions. In the upper face, males had greater interorbital width, frontotemporal brow width, inter-medial canthi distance, and more prominent frontal bossing. In the midface, males exhibited increased width, depth, and vertical height, with the most pronounced differences occurring in middle age. The lower face showed larger mandibular dimensions in males, including bigonial width, ramus height, and a sharper mental angle, while females had a more rounded chin and smoother mandibular contour. Heatmaps confirmed greater surface projection in male skeletons, particularly in the gonial and midfacial regions, with dimorphism decreasing with age. Conclusion: This represents the first large-sample CT study utilizing AI to comprehensively quantify facial skeletal dimorphism. Findings support the importance of gender-specific planning in facial reconstructive and aesthetic procedures.

ABSTRACT Background Sentinel lymph node (SLN) biopsy is a critical staging tool in skin and soft tissue cancers. Although technetium lymphoscintigraphy is the most common adjunct, indocyanine green (ICG) demonstrates a promising alternative in pediatric, adolescent, and young adult (AYA) skin and soft tissue cancers. Methods and Objectives Evaluate the safety and efficacy of ICG in SLN biopsy (SLNB) in diverse pediatric and AYA solid cancers in a multi‐institutional environment. This is a prospective, observational study conducted at 13 member institutions in the Pediatric Surgical Oncology Research Collaborative between 2019 and 2023. Eligible patients underwent SLNB for primary or recurrent solid skin and soft tissue tumors. Peritumoral ICG was administered intraoperatively. Outcomes included SLN detection rates, histopathology of excised specimens, and surgeon‐reported assessment of utility. Safety was assessed through adverse event reporting. Results Forty SLNB procedures yielded 84 specimens: 13 melanoma (32.5%), 12 squamous cell carcinoma (30%), 11 non‐rhabdomyosarcoma soft tissue sarcoma (27.5%), two rhabdomyosarcoma (5%), one Ewing sarcoma (2.5%), and one malignant peripheral nerve sheath tumor (2.5%). Histologic evaluation identified 81 lymph nodes, 75 benign (89.3%) and six malignant (7.1%); three specimens were adipose tissue (3.6%). Of 81 lymph nodes, 76% were ICG‐positive. ICG had a sensitivity of 79.5%, a specificity of 33%, and a positive predictive value of 96%. All malignant nodes were ICG‐avid. There were no adverse reactions to ICG at 30 days. Conclusions ICG is a safe and effective adjunct for SLNB in pediatric and AYA soft tissue and skin malignancies.

Abstract Background Recurrent pericarditis (RP) is an IL-1-mediated chronic autoinflammatory disease (1,2). The phase 3 trial RHAPSODY demonstrated that rilonacept (IL-1α and IL-1β cytokine trap), the first and only FDA-approved treatment for RP, was effective in treating RP not only as a third-line agent (3L; after corticosteroids) but also as a second-line agent (2L; instead of corticosteroids) and reduced recurrence risk as monotherapy (3). The REgiStry Of the NAtural history of recurreNt periCarditis in pEdiatric and adult patients (RESONANCE) has been collecting long-term combined prospective and retrospective data from US-based pericardial-disease-dedicated programs since 2020 (4). Purpose To assess the efficacy of rilonacept in RP in a real-world setting, extending the clinical trial findings of RHAPSODY. Methods Database cut-off (DCO) was 05 February 2025. Data on RP management were collected and analyzed from pts with ≥2 years of observation in RESONANCE. Disease duration at DCO was defined as time from RP diagnosis to either disease resolution (no disease flares while off all RP treatments for ≥6 months before DCO) or last follow-up (for pts with ongoing treatment at DCO). Pericarditis recurrences (investigator-assessed) were confirmed based on RP symptom data and/or objective findings. Annualized recurrence rates were calculated per RP treatment regimen as total pericarditis recurrences divided by total patient-years (PY) while receiving that treatment. Wilcoxon signed-rank test was utilized to analyze the significance in change of annualized recurrence rates before and after rilonacept initiation. Results At DCO, 81 pts had ≥2 years of follow-up data in RESONANCE; mean (SD) age was 51.0 (16.8) years; most (66.7%) were female; 84% had idiopathic etiology; median (Q1-Q3) disease duration was 3.1 (2.6-3.7) years; and median observation was 2.93 (2.54-3.38) years. Patient-year treatment exposures per treatment were: NSAIDS ± colchicine (n=79; 187.8 PY), corticosteroids (n=30; 61.1 PY), anakinra (n=1; 1.2 PY) and rilonacept (n=35; 72.8 PY). Of the 35 pts treated with rilonacept for any duration (median observation: 3.2 years; median time on rilonacept: 2.08 years), the most common reason for rilonacept initiation was chest pain/recurrence on prior treatment (n=28). The annualized recurrence rate while receiving rilonacept was significantly lower versus all combined prior lines of treatment (4.00 vs. 0.02 events per PY; p=0.002); this outcome was consistent across line of treatment for rilonacept use (2L: 3.73 vs. 0.06 events per PY, p=0.02; 3L: 4.14 vs. 0 events per PY, p<0.001; Table 1). Conclusions This first report of real-world outcomes from RESONANCE shows that rilonacept-containing regimens for RP as 1st, 2nd, or 3rd line therapy reduced recurrence risk over long- term (>2 year) treatment, supporting prolonged management during RP natural history.

Abstract Background Vascular Ehlers-Danlos syndrome (VEDS) and Marfan’s syndrome are associated with cardiovascular complications, including arrhythmias. However, atrial fibrillation (AF) risk in these populations has not been frequently reported. This study assessed the AF risk in VEDS and Marfan's syndrome patients using propensity score-matched analysis from an international database. Methods The TriNetX Research Network, an international database with de-identified patient data from over 100 centers, was used to pull patients with a diagnosis of VEDS and Marfan's Syndrome. Baseline characteristics (e.g., demographics, cardiovascular comorbidities, etc.) were collected, and propensity score matching was performed to balance the cohorts. Rates of AF were collected across both cohorts, and risk analysis and Kaplan-Meier survival were used to assess outcomes. Results A total of 1,114 and 23,172 patients had VEDS and Marfan’s syndrome, respectively. After propensity score matching, each cohort included 1,091 balanced patients regarding demographics and clinical characteristics. When compared in the matched cohorts, AF incidence was lower in VEDS (4.6%) compared to Marfan’s syndrome (8.6%), with a risk difference of -0.040 (95% CI: -0.061, -0.020; z = -3.794; p < 0.001). The risk ratio was 0.532 (95% CI: 0.381, 0.742), and the odds ratio was 0.509 (95% CI: 0.358, 0.726), indicating a significantly lower risk of AF in VEDS. Kaplan-Meier analysis showed an AF survival probability of 84.23% in VEDS and 78.20% in Marfan’s syndrome (log-rank p = 0.071). The hazard ratio was 0.723 (95% CI: 0.508, 1.029), which didn’t reach statistical significance (p = 0.579). Conclusion Patients with VEDS have a significantly lower risk of developing AF compared to those with Marfan’s syndrome. However, no significant difference in AF survival probability was observed. These findings suggest significant differences in the arrhythmic burden between these connective tissue disorders, which can direct future risk stratification and management strategies.Figure 1

Abstract Background Marfan syndrome (MFS) predisposes individuals to aortic dissections. Recent data suggest that atrial fibrillation and atrial flutter (AF/AFL) may increase complications and mortality in MFS patients; however, their independent role in aortic dissection remains unclear. Purpose This study aims to assess the risk of aortic dissection in MFS patients with and without AF/AFL. Methods Using the TriNetX database and ICD-10 codes, 2,447 MFS patients with AF/AFL and 20,520 without were identified. Demographics (age, sex, race, ethnicity) were evaluated, and aortic dissection outcomes were compared using risk ratios and Kaplan-Meier survival analysis. Results Patients in the AF/AFL cohort were older (mean age 60.9 ± 16.7 years vs. 38 ± 16.6 years) and had higher proportions of males (62.51% vs. 56.76%) and white patients (74.67% vs. 66.3%). Aortic dissections occurred in 13.9% of MFS patients with AF/AFL compared to 3.4% of those without, resulting in a risk difference of 10.5% (95% CI: 9.0%–11.9%) and a risk ratio of 4.04 (95% CI: 3.547–4.603). Kaplan-Meier analysis revealed significantly lower survival rates in the AF/AFL cohort (74.07% vs. 90.63%; log-rank test, p < 0.0001), with a hazard ratio of 4.232 (95% CI: 3.686–4.858). Conclusion In MFS patients, those with AF/AFL were over four times more likely to experience aortic dissection and had over four times the hazard of mortality. Screening and managing AF/AFL may be essential to preventing aortic dissections and improving outcomes in this population.Figure 1

Abstract Background Vascular Ehlers-Danlos syndrome (VEDS) and Marfan’s syndrome are associated with cardiovascular complications, including arrhythmias. However, ventricular tachycardia (VT) risk in these populations has not been frequently reported. Purpose This study aims to assess the VT risk in VEDS and Marfan's syndrome patients through an international database. Methods The TriNetX database was used to pull patients with a diagnosis of VEDS and Marfan's Syndrome. Baseline characteristics (e.g., demographics, cardiovascular comorbidities, etc.) were collected, and propensity score matching was performed to balance the cohorts. Risk analysis and Kaplan-Meier survival were used to assess outcomes. Results A total of 1,114 and 23,172 patients had VEDS and Marfan’s syndrome, respectively. After propensity score matching, each cohort included 1,091 balanced patients regarding demographics and clinical characteristics. The cohorts were balanced with a mean age of 37.7 ± 16.0 years in both groups. 68.7% and 68.8% were females in the VEDS and Marfan cohorts, the majority being White (82.2% in VEDS, 82.9% in Marfan’s). VT Incidence was lower in VEDS (0.9%) compared to Marfan’s syndrome (2.6%), with a risk difference of -0.016 (p = 0.003). Kaplan-Meier survival showed higher survival in VEDS (99.44%) vs. Marfan’s (94.04%, log-rank p = 0.002). The risk ratio for VT in VEDS was 0.357 (95% CI: 0.174, 0.732). Conclusion VEDS patients have a significantly lower VT risk compared to those with Marfan’s syndrome. These findings suggest significant differences in the arrhythmic burden between these connective tissue disorders, which can direct future risk stratification and management strategies.

Abstract Introduction Cardiac arrest (CA) is the sudden cessation of cardiac activity, leading to haemodynamic collapse and high mortality. Advanced life support (ALS) standardises resuscitation, but the post-return of spontaneous circulation (ROSC) period remains turbulent and poorly understood. Up to 50% of patients who achieve ROSC struggle to maintain spontaneous circulation, leading to re-arrest, typically within minutes. Post-cardiac arrest syndrome (PCAS), involving brain injury and ischaemia-reperfusion injury, plays a key role in re-arrest. Pressure-volume loop (PVL) analysis offers insight into load-independent cardiac biomechanics in the post-ROSC period. The aim of this study is to explore the feasibility of PVL analysis in a swine model of CA. Methods This swine study utilised a ventricular fibrillation (VF) cardiac arrest model in combination with PVL analysis. The experiment included four phases: animal preparation, VF induction, resuscitation, and post-ROSC care. Yorkshire swine (45-70 kg) were sedated, anaesthetised, and VF was induced via an endocavitary electrode attached to a battery. After that, the animals were divided into 3-minute and 6-minute arrest groups before commencing ALS. Standard ALS protocols were followed, including CPR, defibrillation, and drug administration. If ROSC was obtained, animals underwent a 3-hour critical care period. Cardiac indices were compared between baseline and end-of-study values. Results Eight adult Yorkshire swine were enrolled in the study, with a mean weight of 50.2 ± 2.9 kg. VF induction was successfully achieved, and PVL data were collected in all animals except one, establishing a successful porcine VF CA model. In the resuscitation phase, all animals in the 3-minute group achieved ROSC, as opposed to one in the 6-minute group. Post-ROSC metabolic changes included acidaemia, elevated lactate and potassium, partially resolving by study end. Right ventricle PVL data were unreliable, while left ventricle PVL was reliable in 3 of 5 ROSC animals. Preload-recruitable stroke work (PRSW) data were found to be more reliable than the End-Diastolic Pressure-Volume Relationship (ESPVR), with a significant increase in LV PRSW of 34 ± 12% observed post-ROSC in all surviving animals (p<0.001). Discussion This study demonstrates the feasibility of applying PVL analysis to a post-ROSC swine model of cardiac arrest (CA). As expected, warm ischaemic time predicted ROSC, but PVL analysis offered valuable insights into load-independent parameters. While data quality issues hindered ESPVR analysis, PRSW was successfully evaluated, revealing a significant increase post-ROSC, highlighting its potential to guide the development of future therapeutic targets for post-ROSC interventions. The small sample size and technical challenges limited the scope of conclusions, emphasising the need for larger studies.Kaplan-Meier Curve and cycles to ROSC (A) LV PVL, (B) PRSW Pre and Post-ROSC

Abstract Background Nearly 40,000 people in the U.S. experience recurrent pericarditis with up to 90% of cases having no identifiable cause, often making the journey to diagnosis arduous. Understanding the challenges that patients and health care professionals (HCP) face will help address gaps and barriers in patient diagnosis and care. In addition, the lack of U.S. based guidelines for recurrent pericarditis clinical care, coupled with the time lapse from the last published European guideline, has created an opportunity to discover workflow solutions for U.S. based healthcare professionals. Purpose The American Heart Association’s (AHA) Addressing Recurrent Pericarditis Initiative is a three-year effort utilizing a quality improvement approach to address gaps/barriers in patient care, educate HCPs, and develop patient education resources to improve diagnosis, treatment, and quality of life. To accomplish this, the lived experiences and challenges patients face on their journey to diagnosis was integrated into the qualitative research process. Methods To assess quality improvement opportunities, the AHA engaged HCPs with recurrent pericarditis experience from 15 diverse health systems to participate in a learning collaborative strategy for quality improvement and implementation to share successful strategies, provide input on professional education topics, and participate in process mapping. Data collection strategies include 1:1 consultations, quarterly learning collaborative calls, surveys and questionnaire completion. To assess patient education needs, the AHA Market Research Team held 1-hour video interviews with ten diverse patients. Results AHA-led HCP interviews produced process maps of clinical workflows and identified opportunities for standardization to improve clinical workflow and patient outcomes (Figure 1). From these data collection methods, preliminary results include care coordination across clinical settings, exploring treatment options, standardization of follow-up cadence, and provider awareness of misdiagnoses/underdiagnosis rates. The patient interviews revealed that there is a lack of symptom recognition, persistent rate of misdiagnosis, delay in accurate diagnosis and treatment, and discrepancies in diagnosis and treatment for various demographics including female and younger adult patients (Figure 2). Conclusion(s) In Year 2 of this three-year initiative, we will continue to refine identified areas of opportunities to improve patient outcomes by creating and disseminating educational materials and launch awareness campaigns, while also producing a national education series for HCPs that provide guidance for system-level quality improvement to emphasize consistency in care and reductions in health inequities. Key findings from this study highlight the care coordination involved in the treatment of patients with recurrent pericarditis and the need to provide multidiscipline educational approaches to achieve this goal.Figure. 1 Summary of care pathway Figure. 2 Summary of patient interviews
