Background Outcome selection in regional anesthesia and acute pain research is inconsistent, often lacking patient-centered priorities and validated instruments. We aimed to prioritize key outcomes and propose suitable measurement tools to improve the quality, consistency, and relevance of regional anesthesia research. Methods We conducted a multiround Delphi process, including two electronic voting rounds, a multiday in-person meeting, and a patient panel. Experts and patients evaluated existing and proposed outcomes for importance, validity, and relevance. Outcomes reaching ≥70% agreement were prioritized, and appropriate measurement instruments were identified. Results Thirty-two experts and three patients participated. Across three Delphi rounds, 10 outcomes were prioritized for future regional anesthesia research: seven efficacy outcomes (pain scores; opioid consumption; Brief Pain Inventory; functional outcomes; cognitive function; length of stay; block duration); two multidimensional outcomes (quality of recovery and development of a regional anesthesia-specific quality-of-recovery instrument); one safety outcome (chronic postsurgical pain). Patients prioritized cognitive recovery, function, chronic pain, and pain scores. Conclusions This consensus-based, patient-centered framework defines the core priorities for future regional anesthesia and acute pain research. Future work should focus on developing and validating a regional anesthesia-specific quality-of-recovery instrument, refining multidimensional measures such as functional recovery, cognitive outcomes, and the Brief Pain Inventory, and standardizing the reporting of chronic pain and opioid-related outcomes. Adoption of these priorities will enhance methodological consistency, comparability, and patient relevance in future clinical trials.

Abstract Introduction: While evaluation approaches for community-academic research groups are established, few tools exist for academic institutional advisory groups across multi-core centers and research, education, and clinical care missions. Institutional advisory group evaluation should consider group processes and their impact on community-centered outcomes. This study describes the community-engaged development of a mixed-method evaluation approach to address this gap and presents pilot outcomes across an NIH-funded center. Methods: We utilized a Community of Practice model to co-develop a survey with 14 community and academic representatives of four advisory groups. The final survey included five categories of group process and four categories of outcomes. Storytelling sessions with community partners explored areas where the survey identified discrepancies in perspectives between community and academic team members, as well as areas with lower scores. Results: Nine community and 14 academic (staff and faculty) partners completed the survey. Respondents positively assessed group process outcomes (shared values, leadership, community-centeredness, and decision-making), and slightly less positive assessments of institutional outcomes. Storytelling sessions confirmed the overall satisfaction of community partners but highlighted actionable concerns within power-sharing, decision-making, funding equity, and trust-building. Conclusions: The results of this equity-centered evaluation suggest the utility and importance of participatory, mixed-methods approaches to evaluating community-academic institutional advisory groups.

Abstract As Alzheimer's disease (AD) research advances, tau has emerged as both a critical biomarker and a promising therapeutic target, central to understanding disease mechanisms, tracking progression, and guiding treatment development. The Fall 2024 Alzheimer's Association Research Roundtable convened experts from academia, industry, National Institutes of Health (NIH), and the United States Food and Drug Administration (FDA) to explore current progress and future directions in tau‐centered diagnostics and therapeutics. Discussions addressed the integration of tau biomarkers into the 2024 Revised Diagnostic Criteria for AD, updates to amyloid and tau positron emission tomography (PET) imaging, and modeling of biomarker trajectories. Presenters highlighted tau‐targeting therapeutics including antisense oligonucleotides, monoclonal antibodies, and small molecules, alongside innovations in drug delivery. The interplay between anti‐amyloid and anti‐tau therapies and strategic design of combination trials were key themes. Regulatory insights facilitated discussions on drug approval pathways. The meeting highlighted the rapid evolution of tau research and emphasized opportunities to improve diagnostics, trial design, and treatment strategies in AD.

Metastatic meningioma exhibits diverse dissemination patterns across organ systems (lungs, bone, liver, soft tissue, etc), with molecular imaging—particularly gallium 68 DOTA Tyr3-octreotide PET/CT—playing a pivotal role in detection, characterization, and guiding management.

BACKGROUND: Significant disparities persist in timely, guideline-concordant breast cancer treatment across the US, impacting cancer outcomes. The influence of both patient-level and facility-level socioeconomic status (SES) on adherence to Commission on Cancer quality measures remains incompletely understood. STUDY DESIGN: We conducted a retrospective cohort study using the National Cancer Database to assess associations between patient and facility SES and concordance with timeliness of 3 Commission on Cancer breast cancer quality measures: surgery, multiagent chemotherapy, and radiotherapy, among patients diagnosed from 2018 to 2022. Multivariable logistic regression models were used to evaluate predictors of concordant care, including a composite measure of facility-level social risk. RESULTS: The analytic cohorts included 471,425 patients for surgery, 82,734 for chemotherapy, and 311,523 for radiotherapy. Black race, uninsured status, and lower educational attainment were each independently associated with lower odds of receiving guideline-concordant care across all measures. Patients treated at low-SES facilities had higher odds of receiving timely surgery (adjusted odds ratio [OR] 1.27, 95% CI 1.24 to 1.31) but lower odds of receiving timely chemotherapy (OR 0.85, 95% CI 0.79 to 0.91) and radiotherapy (OR 0.95, 95% CI 0.92 to 0.97) compared with those at other institutions. Facility type, fragmented care, and comorbidities also contributed to variation in concordance. CONCLUSIONS: Significant disparities in guideline-concordant breast cancer care persist by race, insurance, education, and facility-level social risk, highlighting intervention opportunities to improve outcomes for these already vulnerable populations. These findings highlight the importance of policy and institutional strategies that address both patient- and facility-level barriers to ensure equitable access to high-quality multidisciplinary treatment.

Abstract Toxicology testing for drugs associated with scenarios such as recreational use or substance use disorder can be performed in support of the emergency department (ED) for specific patient populations such as pediatrics and trauma. These compounds were historically referred to as drugs of abuse (DOA); although the word “abuse” is recognized as potentially stigmatizing, no replacement terminology for DOA has emerged in current guidelines. This document refers to these compounds as drugs or substances of misuse, and acknowledges the need for less-stigmatizing language that more fully encompasses the range of uses for these drugs. This literature-driven, consensus guidance document provides recommendations primarily targeted to US hospital-based laboratories performing urine drug testing (UDT) in support of the ED. Indications for ordering UDT and related testing in both pediatric and adult populations are summarized. Further, recommendations are made for testing that should be available at all facilities with rapid turnaround, and how to perform and report testing. The advantages and disadvantages of immunoassays and mass spectrometry, as well as common challenges, are reviewed. Indications for mass-spectrometry assays and more extensive testing (e.g., novel psychoactive substances) are also provided. Future directions for improvements in laboratory technology to improve the utility of this testing are outlined. All laboratories should collaborate with ED leadership, medical toxicologists and poison control centers to optimize and update test menus to reflect local drug use patterns, ensure test methodologies and results meet clinical needs, and educate clinical staff regarding assay limitations and accurate test interpretation.

PURPOSE Human epidermal growth factor receptor 2 (HER2), a transmembrane receptor with kinase activity involved in cell signaling through the RAS pathway, is expressed in osteosarcoma (OST). Trastuzumab deruxtecan (T-DXd) is an antibody-drug conjugate with a HER2-targeting monoclonal antibody, trastuzumab, linked to a topoisomerase I inhibitor. We report results of a phase II study of T-DXd in adolescents and young adults with HER2-positive relapsed, unresectable OST (ClinicalTrials.gov identifier: NCT04616560 ). METHODS Patients age 12-39 years with relapsed, unresectable OST were eligible for centrally evaluated HER2 expression screening by immunohistochemistry. Patients with >10% of OST cells with cytoplasmic or membranous HER2 expression of any intensity were eligible to receive T-DXd at 5.4 mg/kg intravenously once every 3 weeks for up to 2 years. The study used a 9 + 15 Simon's optimal two-stage design with a primary end point of event-free survival at 24 weeks. RESULTS Fifty patients were screened for HER2, and 41 met the inclusion criteria of 10% of OST cells having membranous or cytoplasmic HER2 expression. Nine eligible patients, two younger than 18 years, were enrolled and received T-DXd. With a single patient having more than 24 weeks of stable disease (SD) of the nine planned in the first stage, this study did not meet criteria to progress to stage II. The estimated SD rate at 24 weeks is 11.1%. The median (range) number of cycles of therapy was 2 (2-12). Grade 3 and 4 possibly related adverse events occurred in three of nine patients and included nausea, vomiting, tumor hemorrhage, cytopenias (n = 3), wound infection, and hypertension. CONCLUSION T-DXd did not demonstrate sufficient activity to expand enrollment to the planned second stage in patients with OST. No new safety signals were observed.

Abstract The da Vinci Single-Port (SP) system is a robotic surgery platform that allows access into the abdominal cavity through a single short surgical incision. The omentum is an attractive donor site for vascularized omental lymph node transfer (VOLT) in the treatment of lymphedema. We hypothesize that SP robotic VOLT will allow for improvement in perioperative outcomes as compared to open laparotomy for omental flap harvest. A retrospective cohort study was performed, comprised of a study sample of patients with a diagnosis of lymphedema who presented to our institution for VOLT using either an open or SP robotic technique between May 2020 and February 2023. The primary outcome was length of hospital stay. The secondary outcomes included intraoperative complication rate, postoperative complication rate, and length of surgery. Fifteen patients underwent da Vinci SP omental flap harvest, and 14 patients underwent open harvest. There was no significant difference in average age, BMI, sex, or lymphedema etiology between the two groups. Average length of stay was 2.2 ± 1.7 days in the SP group and 2.3 ± 2.1 days in the open group (p = 0.91). There were no significant differences in terms of intraoperative or postoperative complications between the two groups. Ninety-three percent of SP robotic and 86% of open patients reported at least partial subjective improvement following VOLT (p = 0.50). Our findings suggest that SP robotic omental harvest for VOLT is feasible. Perioperative outcomes show comparable results in terms of length of hospital stay, complications, and subjective postoperative improvement when comparing the open to the SP approach.

Background Secondary lymphedema frequently occurs following surgery, malignancy, trauma, or radiation and is characterized by limb swelling, discomfort, and recurrent infections. Two advanced supermicrosurgical techniques—lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT)—have recently gained popularity as treatment options. However, long-term outcome data for these procedures remain limited. This systematic review and meta-analysis aim to evaluate the long-term efficacy of LVA and VLNT in patients with secondary lymphedema followed for more than 2 years postoperatively, focusing on outcomes such as cellulitis rates and limb circumference. Methods This study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria encompassed studies involving adult patients with secondary lymphedema treated with LVA or VLNT and with at least 24 months of follow-up. The primary outcomes were annual cellulitis incidence and limb circumference change, analyzed separately for upper and lower extremities. Meta-analysis was conducted using R version 4.3.1. Pooled effect sizes were estimated using random-effects models. Subgroup and sensitivity analyses were also performed. Results A total of 23 studies met the inclusion criteria, covering 648 limbs treated with either LVA (n = 216) or VLNT (n = 432). The weighted average patient age was 56.3 years, and the cohort was predominantly female (99.9%). For LVA, the pooled mean reduction in annual cellulitis events was −1.13 (95% confidence interval [CI], −1.70 to −0.57) for upper extremities and −1.32 (95% CI, −2.08 to −0.55) for lower extremities. VLNT yielded greater reductions in cellulitis, with pooled mean differences of −2.43 (95% CI, −3.36 to −1.50) and −1.38 (95% CI, −2.11 to −0.65) for upper and lower limbs, respectively. Additionally, VLNT reduced limb circumference by 42.7% (95% CI, 36.7–49.7) in upper extremities and 21.98% (95% CI, 19.8–24.4) in lower extremities. Conclusion LVA and VLNT both result in durable, long-term improvements in cellulitis rates, and VLNT was shown to reduce limb circumference. Given the significant impact on patient quality of life, these interventions should remain integral to the treatment algorithm for secondary lymphedema.
