Publication Metadata only Publication Metadata only Cultivating Leaders in the Addiction Behavioral Health Workforce: New England Addiction Technology Transfer Center's Leadership Development Program(2026-03-05)BACKGROUND: The leadership development program (LDP) of the New England Addiction Technology Transfer Center is a novel free professional development training program for addiction behavioral health service providers. The LDP aims to create, develop, and enhance the leadership skills of the addiction behavioral health workforce through multi-component training. The content of the training is scaffolded and covers an array of topics (eg, organizational culture, group development). Instructional content is delivered both virtually and face-to-face and employs various instructional modalities including didactics, behavioral rehearsals, and case studies. METHODS: The current article discusses the development of the LDP, the iterative adaptation of the LDP, and feedback from 69 participants across 5 cohorts. Participants from the 5 cohorts were mostly Non-Hispanic White (73%), identified as female (68%), and had fewer than 5 years supervisory experience (71%). Participants were sent a 2-part post-survey querying for their satisfaction and perceived effectiveness of the program assessed through quantitative and qualitative items. RESULTS: Quantitative items were uniformly answered in the above average to excellent range to questions about the programming, instructors, and usefulness. Similarly, qualitative findings suggested that participants had an overwhelmingly positive experience with the LDP and that they were able to enhance their leadership capabilities. CONCLUSION: Our results provide support for the feasibility and utility of the LDP for addiction behavioral health providers. Additionally, the article provides guidance for the development of leadership training programs to support the leadership development of addiction workforce and the field broadly.Publication Metadata only Neuroform Atlas stent-assisted coiling: jailing versus re-crossing techniques(2026-03-04)BACKGROUND: Stent-assisted coiling (SAC) is an effective, safe, and durable treatment option when considering embolizing wide neck aneurysms. While there are many techniques, the two most common involve jailing a microcatheter behind the stent versus re-crossing the interstices. Despite both techniques being performed in practice, there is a lack of comparison data. This study uses the ATLAS Investigational Device Exemption trial to compare the safety and efficacy of various SAC techniques. METHODS: A total of 298 aneurysms in as many patients were treated in 25 centers with Neuroform Atlas SAC. Technique choice was determined by the operator and involved jailing, re-crossing, or others (jailing followed by re-crossing, stenting followed by re-crossing at a different time). Patient demographics, aneurysm shape, dimension, and location, as well as the number of coils and procedure duration, were analyzed. Procedure and device complications of the different techniques were recorded. Efficacy was evaluated with a core-lab adjudicated 12-month digital subtraction angiography (DSA). RESULTS: Similar aneurysm size and location were observed between the two groups (jailing and re-crossing). There was no significant difference in the number of coils used or the duration of the procedure. There was no significant difference in Raymond-Roy I occlusion rate (89.4% vs 83.9%) at the 12-month DSA or safety events at 12 months. CONCLUSION: There were no significant differences in safety or efficacy for SAC between the jailing or re-crossing technique.Publication Open Access Single-layer spherical (SLS) vs single-layer (SL) Woven EndoBridge (WEB) device in the treatment of narrow-neck intracranial aneurysms: a propensity score-matched analysis(2026-03-03)Data on the use of Woven EndoBridge (WEB) devices in the treatment of narrow-neck intracranial aneurysms (NNA) are limited. We compared the efficacy and safety of single-layer (SL) and single-layer spherical (SLS) WEB devices in treating NNA. We conducted a multicenter retrospective analysis of adult patients with NNA (neck ≤ 4 mm and width-to-neck ratio ≥ 2) treated with SL or SLS WEB devices between January 2011 and December 2022. Patients with fusiform or blister aneurysms, adjunctive treatments, or devices other than SL or SLS were excluded. Propensity score matching was used to adjust for confounding variables. Outcomes included procedural complications, angiographic occlusion rates using the Raymond Roy classification, major device compaction, need for retreatment, and functional outcomes assessed by the modified Rankin Scale (mRS). After matching, resulting in 101 patients in each group, baseline characteristics were well-balanced. Thromboembolic complications occurred in 2.0% of the SLS group and 5.9% of the SL group ( = 0.28). Hemorrhagic complications occurred in 1.0% of the SLS group and 6.4% of the SL group ( = 0.062). Adequate occlusion rates (Raymond Roy grades I and II) were similar between groups (96% in SLS vs. 91% in SL; = 0.20). Major device compaction was significantly less frequent in the SLS group compared to the SL group (0% vs. 7.6%; = 0.024). The need for retreatment trended to be lower in the SLS group (1.1% vs. 6.6% in SL; = 0.12). Functional outcomes (mRS 0–1) at last follow-up were comparable (82% in SLS vs. 86% in SL; = 0.41). In the treatment of narrow-neck intracranial aneurysms, the SLS WEB device was associated with significantly lower rates of major device compaction compared to the SL device. Reduced compaction may lead to a lower need for retreatment. Overall imaging outcomes and safety profiles were similar between the two devices.
