Background: Evidence for Mobile Stroke Units (MSUs) demonstrates that onset to treatment times for intravenous thrombolysis can be reduced and access to mechanical thrombectomy might be improved. Despite growing use of MSUs internationally, to date there have been no studies in NHS England and NHS Wales exploring the acceptability of MSUs to clinicians, patient and public representatives and other key stakeholders, which are important when considering potential feasibility and implementation.

Methods: This study used a mixed methods design with a cross-sectional survey and qualitative workshops and interviews between October 2023 to May 2024.

Background: Two surgical approaches have emerged for axillary staging in cN1 breast cancer patients after neoadjuvant chemotherapy (NAC): sentinel lymph node biopsy (SLNB) and targeted axillary dissection (TAD). Direct comparisons of technical and oncological outcomes with SLNB versus TAD are lacking.

Methods: We routinely performed SLNB from 2017 to 2018 for cN1 breast cancer patients who converted to cN0 after NAC, then adopted TAD from 2019 to 2022.

Article Synopsis
  • This study compared stroke volume estimates from various anatomical sites in healthy dogs and aimed to create reference intervals for specific volume indices like shunt volume and regurgitant volume.
  • Ninety healthy dogs underwent echocardiography to assess stroke volume at different valve levels, with repeat tests for consistency, using methods like Bland-Altman plots for analysis.
  • Results indicated that different echocardiographic methods for measuring stroke volume produced significant variations, highlighting the need for unique reference intervals to evaluate heart conditions in dogs effectively.

Purpose: The nodal burden of patients with residual isolated tumor cells (ITCs) in the sentinel lymph nodes (SLNs) after neoadjuvant chemotherapy (NAC) (ypN0i+) is unknown, and axillary management is not standardized. We investigated rates of additional positive lymph nodes (LNs) at axillary lymph node dissection (ALND) and oncologic outcomes in patients with ypN0i+ treated with and without ALND.

Methods: The Oncoplastic Breast Consortium-05/ICARO cohort study (ClinicalTrials.

The modern generation of trials evaluating the role of adjuvant radiation have turned to genomic profiling as a further risk stratification tool. The LUMINA trial by Whelan et al, published in the New England Journal of Medicine, applied Ki67 testing to identify those with luminal A disease and evaluated locoregional outcomes with Breast Conserving Surgery (BCS) and endocrine therapy (ET) alone. This paper was reviewed at the Canadian Association of General Surgeons' "Evidence-Based Reviews in Surgery" (EBRS) webinar series.
