OBJECTIVE The Woven EndoBridge (WEB) device was approved to treat wide-necked bifurcation aneurysms. The device is designed as an intrasaccular flow disruptor covering aneurysm widths up to 10 mm. Although prior studies combined all aneurysm sizes, it is known that aneurysms behave differently in response to endovascular treatment based on their size. Therefore, the authors’ objective was to identify ideal middle cerebral artery (MCA) aneurysm width and neck sizes most suitable for WEB treatment. METHODS The WorldWideWEB consortium is a large multicenter retrospective database that analyzes intracranial aneurysms treated with the WEB device. In this study, all unruptured MCA bifurcation aneurysms with available measurements were included. Cutoff values based on aneurysm width and neck in relation to aneurysm occlusion status were measured using the receiver operating characteristic (ROC) curve. Propensity score matching (PSM) was then used to compare treatment outcomes between aneurysms smaller and larger than the cutoff value for both width and neck size. RESULTS The ideal cutoff values for MCA bifurcation aneurysm width and neck were 6.1 mm and 4.6 mm, respectively. On PSM, 87 matched pairs were compared based on width size (≤ 6.1 mm and > 6.1 mm), and 77 matched pairs were compared based on neck size (≤ 4.6 mm and > 4.6 mm). There was a significant difference in adequate aneurysm occlusion between aneurysms smaller and larger than those cutoff values for both widths (93% vs 76%, p = 0.0017) and neck sizes (90% vs 70%, p = 0.0026). The retreatment rate was also significantly higher for larger aneurysms in both parameters. CONCLUSIONS This study shows that MCA bifurcation aneurysms ≤ 6.1 mm in width and ≤ 4.6 mm in neck size are significantly better candidates for WEB treatment, leading to improved occlusion status and reduced retreatment rate, which are important considerations when using WEB devices.

160 Background: In the United States, racial/ethnic disparities in adoption of breast cancer evidence-based practices (EBPs) persist along the cancer care continuum. This scoping review applied an implementation science lens to describe the current evidence base for interventions to reduce disparities, synthesizing evidence on effective interventions while highlighting gaps in the literature. Methods: A formalized search strategy identified USA-based interventional studies aiming to improve adoption of an EBP along the breast cancer care continuum among racially/ethnically minoritized patients. Relevant articles from 1/2010 - 8/2022 (Medline, Embase, Cochrane, and Scopus) were included. For each article, two reviewers screened and extracted data, with a third resolving discrepancies. The PRISMA-ScR checklist and JBO Manual for Evidence Synthesis framework were followed. Results: Our search strategy yielded 45,215 articles. After applying inclusion/exclusion criteria, 59 articles were retained, targeting screening (85%, 50 of 59), treatment (12%, 7 of 59), and survivorship (5%, 3 of 59) (2 targeted multiple areas). No articles targeted end-of-life care. Of these, 49% (29 of 59) were randomized controlled trials (RCTs). Among 24 screening RCTs, the most common interventions—and fraction with statistically significant improved screening uptake—were patient navigation (100%, 11 of 11) and patient education (80%, 4 of 5). Among 4 treatment RCTs, 3 targeted adjuvant chemotherapy uptake. Of these, 1 had significant improvements and used patient navigation. The 2 studies without significant improvements used a patient tracking tool/alert system or patient education. Among 2 survivorship RCTs, one used email interventions, resulting in significantly improved physical activity and dietary health. A second used a nurse-facilitated internet support group, resulting in significantly improved physical/psychological symptoms. Early to mid-stage implementation outcomes (acceptability, adoption, appropriateness, feasibility, or fidelity) were commonly measured (81%, 48 of 59). No study measured later stage implementation outcomes (sustainability or costs). Conclusions: In multiple studies, patient navigation and education improved breast cancer screening among racially/ethnically minoritized populations. In one study, patient navigation improved completion of adjuvant treatment. Despite these studies, patient navigation is not reimbursed for cancer screening, and adoption has not been widespread. Future studies should focus on evaluating and improving later stage implementation outcomes (sustainability and costs). Based on these results, insurance reimbursement mechanisms for screening-related navigation may be warranted. Future breast cancer care delivery disparities research should also be expanded to include treatment, survivorship, and end-of-life care.

AbstractThe Psychiatric Pediatric Issues Task Force of the International League Against Epilepsy (ILAE) aimed to develop recommendations for the diagnosis and treatment of anxiety and depression in children and adolescents with epilepsy. The Task Force conducted a systematic review and identified two studies that assessed the accuracy of four screening measures for depression and anxiety symptoms compared with a psychiatric interview. Nine studies met the eligibility criteria for treatment of anxiety and depressive disorders or symptoms. The risk of bias and certainty of evidence were assessed. The evidence generated by this review followed by consensus where evidence was missing generated 47 recommendations. Those with a high level of agreement (≥80%) are summarized. Diagnosis: (1) Universal screening for anxiety and depression is recommended. Closer surveillance is recommended for children after 12 years, at higher risk (e.g., suicide‐related behavior), with subthreshold symptoms, and experiencing seizure worsening or therapeutic modifications. (2) Multiple sources of ascertainment and a formal screening are recommended. Clinical interviews are recommended whenever possible. The healthcare provider must always explain that symptom recognition is essential to optimize treatment outcomes and reduce morbidity. (3) Questioning about the relationship between symptoms of anxiety or depression with seizure worsening/control and behavioral adverse effects of antiseizure medications is recommended. Treatment: (1) An individualized treatment plan is recommended. (2) For mild depression, active monitoring must be considered. (3) Referral to a mental health care provider must be considered for moderate to severe depression and anxiety. (4) Clinical care pathways must be developed. (5) Psychosocial interventions must be tailored and age‐appropriate. (6) Healthcare providers must monitor children with epilepsy who are prescribed antidepressants, considering symptoms and functioning that may not improve simultaneously. (7) Caregiver education is essential to ensure treatment adherence. (8) A shared‐care model involving all healthcare providers is recommended for children and adolescents with epilepsy and mental health disorders. We identified clinical decisions in the management of depression and anxiety that lack solid evidence and provide consensus‐based guidance to address the care of children and adolescents with epilepsy.

BACKGROUND: The supraglottic airway device (SGD) was introduced as a breakthrough in airway management. The Fastrach emerged as the first commercially available intubating SGD, drawing extensive investigation. I-gel is a more recent device that has gained popularity, can be used as an intubating SGD, and replaced Fastrach in many institutions. However, there is uncertainty regarding the comparison between these devices in terms of efficacy for intubation and ventilation, and safety in an airway rescue situation. METHODS: PubMed, EMBASE, Scopus, and Cochrane databases were searched for randomized controlled trials (RCTs) comparing I-gel and Fastrach SGD in adult patients undergoing intubation. The primary outcome was the first-pass success rate for tracheal intubation. Secondary outcomes were tracheal intubation time, SGD insertion time and success, and complications. We computed risk ratios (RRs) to assess binary end points and weighted mean differences (WMDs) for continuous outcomes, with corresponding 95% confidence intervals (CIs) for the primary outcome and its subgroup analysis ( P < .05 was considered statistically significant) and 99% CI after Bonferroni correction for the secondary outcomes ( P < .01 was considered statistically significant). RESULTS: This study included a total of 14 RCTs encompassing 1340 patients. The results indicated a significant difference in the first-pass success rate favoring Fastrach (RR, 0.81; 95% CI, 0.67–0.98; P = .03; I² = 91%). In the subgroup analysis, when a flexible scope was utilized through I-gel, providers achieved a better tracheal intubation first-pass success rate (RR, 1.05; 95% CI, 1.01–1.11; P = .03; I² = 0%), compared with the Fastrach. Overall intubation success rates (RR, 0.92; 99% CI, 0.82–1.04; P = .08, I² = 92%) and time (WMD - 1.03 seconds; 99% CI, -4.75 to 2.69; P = .48; I² = 84%) showed no significant difference irrespective of the device used. There was no significant difference regarding device insertion time by the providers (WMD -6.48 seconds; 99% CI, -13.23 to 0.27; P = .01; I 2 = 98%). Success rates of the providers’ initial SGD insertion and complications such as sore throat (RR, 1.01; 99% CI, 0.65–1.57; P = .95, I² = 33%) and blood presence post-SGD removal (RR, 0.89; 99% CI, 0.42–1.86; P = .68, I² = 0%) showed no significant difference. CONCLUSIONS: Based on our findings, a higher first-pass success rate was observed with the use of Fastrach when compared to I-gel. However, the use of I-gel might result in a better intubation success rate with the flexible scope-guided intubation. There are no significant differences in performance in terms of the success rate for intubation overall, time for device insertion, or time to intubation or complications regardless of the device used.

Abstract Background Cyclin-dependent kinases (CDK) 4/6 inhibitors have significantly improved outcomes for patients with ER+/HER2− breast cancer. Nevertheless, they differ from each other in terms of chemical, biological, and pharmacological features, as well as toxicity profiles. We aim to determine whether QTc prolongation is caused by CDK4/6i in general or if it is associated with ribociclib only. Methods We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs) comparing the prevalence of QTc prolongation as an adverse event in HR+ breast cancer patients treated with CDK4/6i vs those without CDK4/6i. We pooled relative risk (RR) and mean difference (MD) with 95% confidence interval (CI) for the binary endpoint of QT prolongation. Results We included 14 RCTs comprising 16 196 patients, of whom 8576 underwent therapy with CDK4/6i. An increased risk of QTc prolongation was associated with the use of CDK4/6i (RR = 2.35, 95% CI = 1.67 to 3.29, P &lt; .001; I2 = 44%). Subgroup analyses revealed a significant increase in the QTc interval for the ribociclib and palbociclib cohorts. The ribociclib subgroup showed a relative risk of 3.12 (95% CI = 2.09 to 4.65, P &lt; .001; I2 = 12%), whereas the palbociclib subgroup had a relative risk of 1.51 (95% CI = 1.05 to 2.15, P = .025; I2 = 0%). Conclusion Palbociclib was associated with QTc prolongation; however, the relative risk for any grade QTc was quantitively twice with ribociclib. Furthermore, grade 3 QTc prolongations were observed exclusively with ribociclib. These results are important for guiding clinical decision-making and provide reassurance regarding the overall safety profile of this drug class.

Background Endovascular treatment with the woven endobridge (WEB) device has been widely utilized for managing intracranial aneurysms. However, predicting the probability of achieving adequate occlusion (Raymond–Roy classification 1 or 2) remains challenging. Objective Our study sought to develop and validate a predictive calculator for adequate occlusion using the WEB device via data from a large multi-institutional retrospective cohort. Methods We used data from the WorldWide WEB Consortium, encompassing 356 patients from 30 centers across North America, South America, and Europe. Bivariate and multivariate regression analyses were performed on a variety of demographic and clinical factors, from which predictive factors were selected. Calibration and validation were conducted, with variance inflation factor (VIF) parameters checked for collinearity. Results A total of 356 patients were included: 124 (34.8%) were male, 108 (30.3%) were elderly (≥65 years), and 118 (33.1%) were current smokers. Mean maximum aneurysm diameter was 7.09 mm (SD 2.71), with 112 (31.5%) having a daughter sac. In the multivariate regression, increasing aneurysm neck size (OR 0.706 [95% CI: 0.535–0.929], p = 0.13) and partial aneurysm thrombosis (OR 0.135 [95% CI: 0.024–0.681], p = 0.016) were found to be the only statistically significant variables associated with poorer likelihood of achieving occlusion. The predictive calculator shows a c-statistic of 0.744. Hosmer–Lemeshow goodness-of-fit test indicated a satisfactory model fit with a p-value of 0.431. The calculator is available at: https://neurodx.shinyapps.io/WEBDEVICE/ . Conclusion The predictive calculator offers a substantial contribution to the clinical toolkit for estimating the likelihood of adequate intracranial aneurysm occlusion by WEB device embolization.

Background Mechanical thrombectomy has become the standard of care for treatment of acute ischemic stroke secondary to large‐vessel occlusion up to 24 hours from last known normal time. Multiple different techniques for mechanical thrombectomy have been described, including a direct aspiration first‐pass technique and stent retriever thrombectomy. With a direct aspiration first‐pass technique, classically, a large‐bore aspiration catheter is delivered over a microcatheter and microwire to the clot. Recently, a novel macrowire has been introduced as a potential alternative to the use of microwire–microcatheter to allow the delivery of the aspiration catheter. The aim of this study is to develop a multicenter registry comparing delivery of an aspiration catheter for intracranial thrombectomy for acute ischemic stroke secondary to emergent large‐vessel occlusion over a macrowire in comparison with traditional use of microcatheter and microwire. Methods MINT (Macrowire for Intracranial Thrombectomy) is a multicenter, observational study currently enrolling patients with large‐vessel occlusion who underwent mechanical thrombectomy using a macrowire to deliver the aspiration catheter to the intracranial occlusion. All the participating sites will screen and report cases on a monthly basis. The decision to use the macrowire and various aspiration catheters is at the discretion of the interventionalist. Results We will collect patient's clinical, demographic, and radiographic data. In addition, we plan to collect procedure variables and postprocedure clinical and imaging data. Outcomes include successful delivery of the reperfusion catheter to the clot interface, time taken from groin access to first pass, and a bailout strategy for thrombectomy in cases where this is not feasible. Conclusion The MINT registry will add to our understanding of safety and efficacy of this novel macrowire in intracranial thrombectomy. This registry will also highlight and allow for understanding in workflow improvements from simplifying setup and possibly cost effectiveness of this technique.

e16301 Background: Outcomes for patients with Stage 3 pancreatic ductal adenocarcinoma (PDAC) remain poor with a mean overall survival (OS) of 11 months. Irreversible electroporation (IRE) is a method of local tumor ablation that causes cell death by disrupting homeostasis in the cell membrane. Previous research suggests IRE can be useful in the multi-disciplinary treatment of Stage 3 PDAC. The present study was designed to assess the effectiveness and safety of IRE for Stage 3 PDAC in a real-world setting after induction chemotherapy. Methods: Patients with Stage 3 PDAC treated with IRE were prospectively enrolled in a multicenter registry study. Enrollment required 3 months of active multi-agent chemotherapy, with no progression before IRE treatment. Endpoints were 30- and 90-day mortality from enrollment and the new onset of an adverse event (AE). Results: 87 patients were enrolled in the registry between May 2019 and May 2023. Mean age was 64.0 ± 8.4 years, 57.5% were female and mean tumor diameter was 2.2 ± 0.7 cm. Mean time from diagnosis to IRE treatment was 8.9 ± 4.9 months. All subjects underwent induction chemotherapy with the most common being FOLFIRINOX alone, gemcitabine with albumin-bound paclitaxel, or a combination of both in 47 (54.0%) patients. Thirty-seven (42.5%) patients had prior radiation therapy. All procedures were performed using an open approach with 50 (57.5%) for in-situ tumor ablation and 37 (42.5%) with the intent of margin accentuation in combination with resection. Major adjunctive procedures were performed for 70 (80.5%) patients. Common adjunctive surgeries were cholecystectomy (33.3%), Whipple procedure (28.7%) and either distal or subtotal pancreatectomy (11.4%). Mean IRE delivery time was 55.7 ± 54.5 minutes with an average of 3.1 probes (range 2 to 6) used per procedure. There was a mean of 1031.1 ± 882.1 pulses delivered per procedure. The 30- and 90-day mortality was 3/87 (3.4%) and 4/82 (4.9%) respectively. There were 21 (24.1%) patients who developed AEs related to IRE treatment during the 90-day post-procedure period (9 patients had AEs that were definitely related to IRE, 5 probably and 7 possibly). Of these related events, only three were Grade 4 or higher (arterial hemorrhage, cardiac arrest, and septic shock). Overall, gastrointestinal related AEs were the most common representing 16 of the 28 (57.1%) of all AEs associated with the IRE procedure. One patient died within 30 days of the procedure due to an intraperitoneal arterial hemorrhage that was deemed to be definitely related to the IRE treatment. Conclusions: The use of IRE for curative intent tumor ablation alone or in combination with resection following induction chemotherapy in patients with locally advanced Stage 3 PDAC has acceptable safety and is associated with acceptable morbidity and mortality rates in appropriately selected patients.

Abstract Background Delirium is a common complication of older people in hospitals, rehabilitation and long-term facilities. Objective To assess the worldwide use of validated delirium assessment tools and the presence of delirium management protocols. Design Secondary analysis of a worldwide one-day point prevalence study on World Delirium Awareness Day, 15 March 2023. Setting Cross-sectional online survey including hospitals, rehabilitation and long-term facilities. Methods Participating clinicians reported data on delirium, the presence of protocols, delirium assessments, delirium-awareness interventions, non-pharmacological and pharmacological interventions, and ward/unit-specific barriers. Results Data from 44 countries, 1664 wards/units and 36 048 patients were analysed. Validated delirium assessments were used in 66.7% (n = 1110) of wards/units, 18.6% (n = 310) used personal judgement or no assessment, and 10% (n = 166) used other assessment methods. A delirium management protocol was reported in 66.8% (n = 1094) of wards/units. The presence of protocols for delirium management varied across continents, ranging from 21.6% (on 21/97 wards/units) in Africa to 90.4% (235/260) in Australia, similar to the use of validated delirium assessments with 29.6% (29/98) in Africa to 93.5% (116/124) in North America. Wards/units with a delirium management protocol [n = 1094/1664, 66.8%] were more likely to use a validated delirium test than those without a protocol [odds ratio 6.97 (95% confidence interval 5.289–9.185)]. The presence of a delirium protocol increased the chances for valid delirium assessment and, likely, evidence-based interventions. Conclusion Wards/units that reported the presence of delirium management protocols had a higher probability of using validated delirium assessments tools to assess for delirium.
