PURPOSE Patients with breast cancer requiring postmastectomy radiation therapy (PMRT) often desire breast reconstruction. Reconstructions can be adversely affected by PMRT, and fear of reconstruction complications has discouraged adoption of short-course radiation therapy used after lumpectomy. To fill the evidence gap, we conducted a noninferiority trial of hypofractionated versus conventional PMRT in patients undergoing breast reconstruction. The primary outcome was reconstruction complication rate, a composite of wound healing, readmission, capsular contracture, unplanned reoperation, and reconstruction failure. METHODS Women with unilateral invasive breast cancer with planned immediate or delayed reconstruction and PMRT were randomly assigned (1:1) to 50 Gy (25 fractions/5 weeks) or 42.56 Gy (16 fractions/3 weeks). This study was designed with a noninferiority margin of 10%, assuming a 2-year reconstruction complication rate of 25% with conventional PMRT. Randomization was stratified by immediate versus delayed and autologous versus implant-only reconstruction. RESULTS Between 2018 and 2021, 898 patients enrolled with a median follow-up of 3.9 years; 825 patients were evaluable for the primary end point. The 24-month reconstruction complication rates were 12.3% (52/422) with hypofractionated PMRT and 10.2% (41/403) with conventional PMRT, corresponding to an estimated difference of -2.1% (95% CI, -6.5 to 2.2). The complication rate was higher (regardless of arm) with implant-only versus autologous reconstruction (odds ratio = 1.65). There was no statistically significant difference in 36-month locoregional recurrence rates: 1.5% (95% CI, 0.7 to 3.2) with hypofractionated and 2.2% (95% CI, 1.1 to 4.3) with conventional PMRT. Acute and late toxicity rates were not statistically different. CONCLUSION A 16-fraction course of hypofractionated PMRT is safe and noninferior to conventional PMRT in women undergoing breast reconstruction after mastectomy.

ABSTRACT Aims This study aimed to describe how emergency nurses (ENs) experience secondary traumatic stress (STS) within their practice environments, focusing on the strategies they use to cope and the supportive resources they draw upon to manage its impact on their lives. Design This paper presents the qualitative findings from a larger mixed‐methods survey study on STS among ENs. Methods A geographically diverse U.S. sample of ENs was recruited through social media to participate in an online survey. All participants ( n = 275) were asked to respond to open‐ended survey questions, and 118 of these participants provided answers to at least one open‐ended question. A self‐selected sample of 20 ENs completed semi‐structured interviews. Inductive content analysis was used to analyse open‐ended survey responses and interview transcripts. Results Three themes reflected ENs' experiences with STS: STS Is Real—It's Going to Affect Your Life; Something Must Be Wrong With Me: A Culture of Disconnection; and It's a Systems Issue, but We're in It Together. Participants described individual, unit, and organizational factors that influenced their experiences of STS and their access to and use of coping strategies and supportive resources. Conclusion ENs and nurse leaders acknowledged the impact of STS on their personal and professional lives and emphasized how the practice environment shaped their experiences. They perceived the accessibility of organizational resources, leadership behaviours, and team culture as influencing the individual strategies ENs use to manage the effects of repeated exposure to others' traumatic experiences. STS is a predictable occupational hazard for ENs; thus, healthcare organizations must invest in nurse‐identified supports to preserve workforce well‐being and clinical expertise. Implications for the Profession Assessing organizational readiness to address STS is recommended to ensure ENs receive effective, timely support. In response to these assessments, healthcare organizations should develop and implement policies that prioritize the mental health and well‐being of ENs, including proactive support systems and accessible mental health resources. Impact This study identifies participant‐perceived individual, team, leadership, and organizational conditions that may hinder or support ENs' management of STS. These findings identify potential targets for organizational assessment and support strategies intended to foster healthier practice environments and promote safe, high‐quality care. Reporting Method Consolidated Criteria for Reporting Qualitative Research (COREQ).

Abstract Enfortumab vedotin (EV), pembrolizumab, and EV plus pembrolizumab (EV/P) have rapidly reshaped the treatment landscape of advanced urothelial carcinoma, but toxicity increasingly determines treatment delivery, treatment continuity, and real-world benefit. As EV/P moves into broader clinical use, clinicians must distinguish adverse events related to antibody-drug conjugate exposure from immune-mediated toxicities and recognize syndromes in which both mechanisms may contribute. In this practical, mechanism-informed review, we synthesize pivotal trials, mature follow-up reports, and representative real-world cohorts describing the safety of EV monotherapy, pembrolizumab monotherapy, and EV/P in urothelial carcinoma. Because adverse-event reporting and ascertainment are heterogeneous across studies, including differences in preferred terms, composite categories, grading frameworks, and treatment-related versus all-cause reporting, we emphasize clinically interpretable patterns rather than pooled estimates. EV monotherapy is characterized by cutaneous toxicity, peripheral neuropathy, hyperglycemia, dysgeusia, and ocular events, including early epithelial/metabolic events and cumulative neuropathy. Pembrolizumab monotherapy has a lower overall high-grade toxicity burden but is defined by immune-mediated endocrinopathies, pneumonitis, hepatitis, colitis, and nephritis. Combination therapy produces a predictable overlap of these toxicity domains, creating diagnostic and management challenges for syndromes such as skin toxicity, diarrhea, fatigue, and pulmonary symptoms. We provide comparative visual toxicity signatures, regimen-specific summary tables, temporal toxicity mapping, and a pragmatic attribution framework that classifies events as EV-predominant, immune-predominant, overlap/indeterminate, or high-risk requiring initial interruption of both agents. This review aims to support bedside recognition, provisional attribution, early management, and safer implementation of EV/P in contemporary urothelial carcinoma practice.

Objectives: Pulmonary function tests (PFTs) are essential for diagnosis, management, and follow-up of a wide range of respiratory conditions as they provide quantitative insights into various aspects of lung function. Precision in ordering and scheduling PFTs, like any test, is crucial as errors can lead to misdiagnoses, delayed treatments, unnecessary retesting, inflated healthcare costs, and potentially compromised patient care. Hence, the aim of this quality improvement initiative was to reduce the PFT ordering error rate to below 5% by redesigning the ordering workflow and implementing a standardized order set tailored to specific clinical scenarios. Methods: The quality improvement initiative was implemented from August 2023 to March 2024. Data was collected from the electronic medical record (EMR) using predefined operational definitions to identify incorrect PFT orders and scheduling errors. A redesigned orderset was created to align with specific clinical presentations, including symptoms, suspected diagnosis, confirmed diagnosis, and presurgical evaluation. Scheduling was also restructured to match the expected testing time for each category. Education sessions were conducted with ordering providers, and ongoing feedback loops were established. Results: Among 575 preintervention PFT orders, 130 (22.6%) contained errors. Following implementation, review of 607 postintervention orders showed a reduction in error rates to 4.1%, representing an ∼80% improvement ( P <0.01). There was no increase in unnecessary testing, supporting the effectiveness of the intervention without unintended negative consequences. Conclusions: Implementation of a knowledge-based CDSS with standardized order sets significantly reduced PFT ordering errors and variability, improving guideline adherence and care quality. Continued refinement and integration with evolving technologies are essential for broader applicability.

Eye-tracking provides an objective measure of how observers direct visual attention to presented stimuli and has become an increasingly valuable tool in facial plastic surgery. It offers unique insight into how facial conditions and surgical interventions impact facial attention. A well-designed eye-tracking study can address patient questions about how others look at their face, identify targets for visual improvement, and objectively assess facial plastic surgery outcomes. Significant variability exists in eye-tracking study design and execution within facial plastic surgery, often producing data that are erroneous, difficult to interpret, or not generalizable to clinical practice. There are currently no guidelines for the design of eye-tracking studies in facial plastic surgery. Furthermore, the technical requirements for facial eye-tracking studies differ from those for non-facial studies. This article aims to synthesize the existing literature and authors’ experience to establish basic guidelines for designing eye-tracking studies in facial plastic surgery. We hope this guide will help investigators design high-quality eye-tracking studies to drive meaningful advances in the field of facial plastic surgery.

Abstract Objective The goal of this study was to synthesize the evidence on how “status migrainosus” is defined in research studies in comparison to established International Classification of Headache Disorders (ICHD) criteria. Background Current ICHD‐3 criteria define status migrainosus as a headache attack occurring in a patient with a history of migraine with or without aura that is typical of previous attacks except for its duration (>72 h) and severity (debilitating). Despite the ICHD criteria, there are varying inclusion criteria noted in studies enrolling patients with status migrainosus. With this diagnostic uncertainty, there remains difficulty in studying this patient population. Methods This systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines. Ovid MEDLINE, Ovid EMBASE, All Evidence‐Based Medicine Reviews, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov , and the World Health Organization International Clinical Trials Registry Platform were searched with the end search date of August 29, 2025. We included studies that were original research focused on status migrainosus, published in English after January 1, 1988, and also included diagnostic criteria to define this condition. The abstracts and full texts were screened by independent reviewers, with a third independent reviewer remaining available to settle disputes. There were 45 studies that underwent full text review, with 19 of these studies included. Data extraction was conducted recording the criteria used to define status migrainosus, headache characteristics, and goals of each study. Results We identified four common domains among studies of status migrainosus, including use of ICHD criteria, headache duration, symptom severity, and treatment response. Reference to ICHD criteria was variable, with only 68% (13/19) of studies specifying an edition of ICHD criteria applied in recruiting or studying patients with status migrainosus. The majority of studies (16/19; 84%) used a headache duration greater than 72 h to define status migrainosus. The use of symptom severity with “debilitating” or “severe” was present in 63% (12/19) of studies and depended on the edition of ICHD criteria that was referenced. Treatment response was rarely used as a condition in defining status migrainosus, with only 15% (3/19) of studies utilizing this stipulation in diagnostic criteria. Conclusion The results of this systematic review show inconsistent application of ICHD criteria in research studies focusing on status migrainosus. These inconsistencies lead to ambiguity in how status migrainosus is defined in the research setting and limit the ability to replicate or compare studies. Guidelines outlining best practices for research of status migrainosus are necessary. For prospective studies, consistent utilization of ICHD criteria is necessary, with potential need to revise these criteria to better reflect the clinical realities of this entity. For retrospective studies, implementation of a standardized International Classification of Diseases code for status migrainosus would be of benefit to improve diagnostic clarity because the current codes are lengthy, cumbersome, and unclear.
