The recent approval of encorafenib, cetuximab, and FOLFOX based on the phase III BREAKWATER trial has introduced a new standard of care for the first-line treatment of BRAF V600E–mutated metastatic colorectal cancer (mCRC). However, its safety and efficacy in patients with significant liver dysfunction remains unclear and, as such, patients are often excluded from pivotal clinical trials. This report presents a case of BRAF V600E–mutated mCRC presenting with extensive hepatic involvement and liver dysfunction. Despite the absence of guidelines, the patient was initiated on full-dose encorafenib, cetuximab, and FOLFOX. He experienced a rapid clinical and biochemical response, with near-normalization of liver enzymes after cycle 1, and complete functional recovery by cycle 3. Treatment was well tolerated, with no significant adverse events throughout 9 cycles. He subsequently transitioned to maintenance 5-FU, cetuximab, and encorafenib. Posttreatment blood-based next-generation sequencing revealed no residual actionable mutations. The patient then successfully underwent complete surgical resection of his primary tumor and metastatic disease with negative margins. This case highlights the importance of considering encorafenib-based therapy in select patients with BRAF V600E–mutated mCRC in the setting of compromised liver function.

A 46-year-old female was admitted to the hospital for confusion, cognitive decline, and hallucinations with alcohol withdrawal. Her history was notable for Alcohol use disorder (AUD) and family history of Alzheimer's disease (AD). Comprehensive workup was unrevealing for metabolic encephalopathy, infection, or nutritional deficiencies. Phosphatidyl ethanol level was 1181, indicating severe alcohol misuse. Phospho-Tau 217 testing raised suspicion of AD and FDG-PET scan confirmed patterns consistent with early onset AD. AUD can precipitate earlier or more severe onset of AD. Phospho-Tau 217 can be a useful screening marker to identify people at risk of AD to prompt intensive treatment.

Objectives: The electroconvulsive therapy for the acute management of severe agitation in dementia (ECT-AD) trial is a multisite study evaluating the effectiveness of ECT for severe agitation in individuals with advanced dementia. Given that participants lack decisional capacity because of advanced cognitive impairment, the trial required a structured and ethically sound approach to obtaining informed consent and assent across jurisdictions with differing legal requirements, including Massachusetts, New York, Georgia, Minnesota, and Michigan. This paper describes the approach used in the study. Methods: We describe the consent framework developed for the ECT-AD trial, including procedures for identifying legally authorized representatives, complying with state-specific laws for ECT consent, obtaining surrogate consent for research participation, and assessing patient assent and dissent using a standardized tool. Conclusions: The approach used in this study may serve as a practical model for future research involving individuals without decision-making capacity and legally complex interventions such as ECT.

Background: While surgeon burnout is extensively documented, the medical community has limited corresponding data regarding what it might mean to thrive in the profession as captured by robust measures of “flourishing.” Study Design: We conducted a cross-sectional survey measuring flourishing in a sample of 1,000 practicing US surgeons from the American Medical Association Masterfile between September and December 2025, including the Harvard Flourish Index (FI) and Secure Flourish Index (SFI). We used multivariable regression to assess personal and professional correlates of flourishing. Results Of 959 eligible surgeons in our sample, 283 (30%) responded. Mean flourishing (SFI) score was 7.98 (± 1.21) on a 0-10 scale (higher score=higher flourishing). Surgeons reported the highest flourishing in "Financial and Material Stability" (8.57 ± 2.11) and "Meaning and Purpose" (8.50 ± 1.39), while "Close Social Relationships" (7.41 ± 2.08) was the lowest-ranked domain. In multivariate linear regression, working fewer hours (adjusted β (each additional hour), -0.02; p<0.001), having children (adjusted β, 0.43; p=0.05) and viewing surgery as a calling (adjusted β, 0.28; p=0.006) were associated with higher flourishing. A majority (88%) of surgeons view the profession as a calling. Conclusion: Practicing surgeons report high levels of flourishing, with scores surpassing several historical medical and non-medical cohorts. Most surgeons reported comparatively high scores in meaning and purpose concurrent with deficits in social connectivity. Burnout and well-being conversations in the surgical professions may benefit from a flourishing framework. Naming meaning and purpose exemplars while being able to identify key deficits like social connectivity may be crucial for helping surgeons thrive.

Interlobular septal thickening (ILST) is a feature on chest computed tomography (CT) that is characterized by abnormal widening of the interlobular septa, which are thin connective tissues that separate secondary pulmonary lobules within the lung parenchyma. They contain pulmonary venules and lymphatic vessels. On CT, these septa are normally not visible in healthy patients. However, various pulmonary pathologic conditions can lead to ILST. If present, ILST can be categorized into 3 different patterns based on its morphologic appearance: smooth, nodular, and irregular/fibrotic. Each pattern occurs from different disease processes with little overlap. In this pictorial essay, we review common and rare etiologies for each type of ILST. For each disease, we discuss relevant pathophysiology, epidemiology, risk factors, symptoms, physical exam findings, labs, and management. Subsequently, we present the ILST features along with the distribution (eg, unilateral, bilateral, central, peripheral) and ancillary imaging findings that can support the diagnosis. Finally, characteristic and high-resolution figures are presented.

Purpose: Neuroendocrine neoplasms (NENs) are increasingly recognized to have a hereditary predilection, yet the prevalence and clinical relevance of pathogenic germline variants (PGVs) in unselected patients with NEN remain poorly defined. This prospective, multicenter study aimed to evaluate the prevalence and clinical utility of PGVs through universal multigene panel testing in a diverse cohort of patients with NENs. Patients and Methods: Between 2018 and 2024, we enrolled unselected patients with NENs from 3 Mayo Clinic Cancer Centers. Germline genetic testing was performed using a next-generation sequencing panel of up to 84 cancer predisposition genes. Patients were not selected based on age, disease stage, ethnicity, or family history. Variants were classified as PGVs, variants of uncertain significance (VUS), or negative. Clinical and demographic data were analyzed descriptively. Results: Among 88 patients, PGVs were identified in 15.9% (n=14), most frequently in high- or moderate-penetrance genes including MEN1 , CHEK2 , MITF , and MUTYH . PGVs were most commonly found in pancreatic NENs [n=12/55 (21.8%)], followed by small bowel NENs [n=2/20 (10%)], with no PGVs detected in lung NENs. Mismatch repair (MMR) gene alterations were identified in 5.7% of patients, including 1 MLH1 PGV and 4 MSH2/MSH6 VUS, 2 of which demonstrated MMR deficiency by protein testing. VUS were reported in 34.1% of patients. Notably, 35.7% of PGV-positive patients did not meet current NCCN or ACMG testing criteria, and 53.9% had PGVs in genes outside of cancer-specific guideline recommendations. Conclusions: Universal germline testing in unselected patients with NEN identified clinically relevant PGVs in over 15% of cases. These findings support broader genetic testing approaches to guide treatment, enhance familial risk assessment, and inform cascade testing—regardless of traditional clinical selection criteria.

Importance Stool metabolites influencing gut motility and sensation may contribute to fecal incontinence (FI). Objective The objective of this study was to test whether FI is associated with higher levels of butyrate and Clostridiales taxa in stool. Study Design Stool metabolites and microbiota were compared between 96 women with FI and 42 controls. FI frequency and subtype (urgency vs insensible) were measured using a 14-day bowel diary, St. Mark’s score, and the Accidental Bowel Leakage questionnaire. Metabolite analysis included targeted analysis (8 short-chain fatty acids including butyrate, 17 bile acids, and 8 tryptophan derivatives) and untargeted analysis. Stool microbiota were characterized using 16S rRNA gene sequencing. Multivariable and exploratory multiomics factor analysis were performed with statistical significance defined as false discovery rate (FDR) ≤0.10. Results The FI group had a higher proportion of Bristol stool types 2 and 6 than controls ( P = 0.005). The mean number of leaks for the FI group was 1.7 ± 1.7 per day, 38% had urgency FI, and 39% had insensible FI. There was no significant difference between groups in butyrate levels and Clostridiales taxa. Multiomics analysis identified glycerolipids (monoacylglycerols and diacylglycerols) associated with FI (FDR = 0.08). In addition, insensible FI was associated with glycerolipids, long-chain saturated and monounsaturated fatty acids, phospholipids, and dipeptides (FDR = 0.08–0.09). The top weighted microbiota associated with these metabolites were Lachnospiraceae and Ruminococcaceae; however, these taxa were not directly associated with FI. Conclusion Butyrate and Clostridiales were not associated with FI. Novel stool metabolite signatures were identified, suggesting new biological pathways and potential therapeutic targets for FI.

ABSTRACT One quarter of patients with diffuse large B‐cell lymphoma (DLBCL) who achieve a complete response following front‐line therapy will eventually experience disease relapse. Existing prognostic models use baseline factors to predict outcomes from the start of initial therapy and are not intended for use following completion of treatment. We developed a conditional event‐free survival (cEFS) tool that predicts a patient's risk of lymphoma recurrence after completing front‐line therapy taking into consideration baseline risk characteristics plus the time the patient has been in remission. Model development used pooled and harmonized data from two observational cohorts and four randomized trials of patients with newly diagnosed DLBCL treated with immunochemotherapy and either achieving a complete response or not experiencing an event within 12 weeks of end of therapy. Cox proportional‐hazards regression modeling with backwards stepwise selection was utilized for model development. External validation was performed using a large independent data registry. In total, data from 2757 patients were used for model development. The risk of experiencing an event at a time point after having survived a period of time could be computed parsimoniously using four basic predictors: age, ECOG performance status grade, Ann Arbor stage, and lactate dehydrogenase level. C‐index in the model development cohort was 0.65 (95% CI, 0.63–0.68), compared to 0.64 (95% CI, 0.62–0.66) in the external validation cohort. We believe that this dynamic risk prediction tool will not only aid clinicians in providing data‐driven recommendations for surveillance, but also assist patients themselves with key decisions, such as family planning.

Abstract Clinical medical physics is a profession that intersects with various groups as part of a broader healthcare team, including dosimetrists, radiation therapists, radiologic and MRI technologists, IT specialists, and physicians. Success in this field requires academic and technical excellence as well as comprehensive skills for working effectively within an interdisciplinary healthcare team. When hiring medical physics residents, the selection of well‐rounded and highly qualified candidates can be facilitated through a holistic review process that ensures consideration of traditional metrics such as academic performance while also accounting for the importance of various experiences, personal attributes, and intrinsic motivations that impact clinical performance and patient care. The Association of American Medical Colleges (AAMC) emphasizes an overall consideration of Experiences, Attributes, Competencies, and Metrics (EACM) as important for the search process. As part of the healthcare community, medical physics shares the same commitment to high‐quality patient care. By adopting the AAMC's EACM framework, medical physics residency programs can strengthen the fairness, rigor, and overall effectiveness of their application review processes—ultimately benefiting applicants, the medical physics community, and the patients we serve. This Society of Directors of Academic Medical Physics Programs (SDAMPP) task report aims to provide information and resources for applying holistic review to the applicant selection process for medical physics residency programs. Our objective is to enable program directors to reevaluate their selection methods in the context of institutional and program missions and goals and to improve the quality and specificity of recruitment by integrating holistic review concepts into their residency recruitment processes. This initiative can inspire change in recruitment practices, aid programs in hiring well‐rounded and well‐qualified residents, and support the professional growth of our trainees in healthcare. This report provides an overview of holistic reviews and its core principles. We review the current literature and provide evidence from successful implementations of holistic review in other medical fields to illustrate how it can benefit our field. Furthermore, we outline actionable recommendations to facilitate transitioning to a holistic review framework and address potential barriers with practical solutions. A supplemental workbook is provided to guide residency programs in developing their own holistic application review and interview processes. With this report, we aim to provide practical implementation guidelines that will allow residency program directors to implement a selection methodology that comprehensively assesses the full qualifications of individual candidates and ultimately fosters the development of versatile and competent clinical medical physicists who are best equipped to advance the field, meet patient needs, and improve patient care.

Purpose of review A substantial proportion of esophageal adenocarcinoma (EAC) and high-grade dysplasia (HGD) cases in Barrett's esophagus (BE) are diagnosed after a dysplasia-negative endoscopy before the next recommended surveillance interval. These are classified as postendoscopy esophageal carcinoma (PEEC) or postendoscopy esophageal neoplasia (PEEN) and represent critical failures of BE surveillance. This review summarizes current definitions, epidemiology, potential etiologies, and evolving strategies to reduce PEEC/PEEN and improve the quality of BE surveillance. Recent findings High-quality endoscopic examination using high-definition white-light endoscopy (HD-WLE) and virtual chromoendoscopy (CE), adherence to the Seattle biopsy protocol, adequate inspection time, and training in the recognition of visible lesions harboring prevalent dysplasia/EAC, are critical in reducing PEEC/PEEN. Initial data on the use of adjunctive tools (wide-area transepithelial sampling) and molecular biomarkers (p53, DNA methylation panels, and Tissue Systems Pathology tests) demonstrate promising results for detecting prevalent dysplasia and for reducing PEEC and PEEN. BE surveillance quality metrics, such as cancer and neoplasia detection rates, have been shown to be inversely associated with PEEN. Summary PEEC and PEEN reflect critical gaps in the effectiveness of BE surveillance. Improving the quality of endoscopic surveillance is essential, including meticulous mucosal inspection, appropriate use of advanced imaging techniques, and adherence to systematic biopsy protocols, to minimize missed neoplasia.
