IMPORTANCE Neoadjuvant chemoimmunotherapy has high rates of pathologic response and improved prognosis among solid tumors. Its role in head and neck squamous cell carcinoma (HNSCC) remains understudied. OBJECTIVE To summarize the efficacy associated with neoadjuvant chemoimmunotherapy regimens in HNSCC and to compare the efficacy associated with neoadjuvant chemoimmunotherapy vs immunotherapy alone in locoregionally advanced resectable HNSCC prior to definitive surgery. DATA SOURCES A librarian-led systematic review was conducted using multiple electronic databases, including Medline, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus, following Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) guidelines. Databases were queried from inception to October 2024. STUDY SELECTION Inclusion criteria included prospective interventional trials that have completed accrual, with results published in English. Only trials of resectable, treatment-naive HNSCC were included. Exclusion criteria included lack of reporting on pathologic response or Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 response. DATA EXTRACTION AND SYNTHESIS Two investigators independently conducted title, abstract, and full-text reviews per PRISMA guidelines. Primary outcomes extracted were major pathologic response (MPR) and complete pathologic response (CPR) at surgery and complete response (CR) on imaging by RECIST 1.1. Secondary outcomes included 1-year overall survival (OS) and toxic effects. MAIN OUTCOMES AND MEASURES A meta-analysis was performed using a binary random-effects model to determine the pooled proportion of primary outcomes in the immunotherapy and chemoimmunotherapy groups. Heterogeneity was reported as I 2 . RESULTS A total of 751 patients (502 [77%] male; age range, 27-87 years) across 23 studies were included in the meta-analysis, including 357 patients (47%) who underwent chemoimmunotherapy, 102 patients (14%) who underwent dual-agent immunotherapy, and 292 patients (39%) who underwent single-agent immunotherapy. Pooled rates of MPR plus CPR were 66% (95% CI, 58%-73%; I 2 = 0.59) for chemoimmunotherapy, 18% (95% CI, 6%-29%; I 2 = 0.65) for dual-agent immunotherapy, and 6% (95% CI, 3%-9%; I 2 < 0.01) for single-agent immunotherapy. Across all groups, 1-year OS rates ranged from 88% to 96% for single-agent immunotherapy, 88% to 96% for dual-agent immunotherapy, and 88% to 100% for chemoimmunotherapy. Grade 3 to 5 adverse events were reported in 61 of 210 patients (29%), 2 of 67 patients (3.0%), and 36 of 210 patients (17%) among the reporting studies in the single-agent immunotherapy, dual-agent immunotherapy, and chemoimmunotherapy groups, respectively. CONCLUSIONS AND RELEVANCE These findings suggest that neoadjuvant chemoimmunotherapy regimens were associated with higher pathologic and radiographic response rates compared with immunotherapy alone in locoregionally advanced HNSCC. These results call for phase 3 trials comparing these neoadjuvant regimens head to head.

ABSTRACT Recent advances in the diagnosis and management of reflux disease were the central focus of the inaugural Gatherings in Esophagology (GiE), which convened experts across gastroenterology, surgery, otolaryngology, pulmonology, and basic research. The sessions highlighted innovations in reflux monitoring—including high‐resolution manometry, wireless pH monitoring, and novel salivary biomarkers—while critically evaluating their diagnostic accuracy and clinical utility. Presentations explored the limitations of traditional proton‐pump inhibitor therapy, the emergence of potassium‐competitive acid blockers as a new class of acid suppressants, and the evolving role of adjunctive treatments such as mucosal protectants, reflux reducers, and neuromodulators for refractory symptoms. The discourse extended to advanced interventional procedures, including transoral incisionless fundoplication, magnetic sphincter augmentation, and the RefluxStop device, with discussion of patient selection, efficacy, and complication management. Discussants emphasized the pathophysiology and management of extraesophageal manifestations of reflux, the interplay between reflux and pulmonary disease, and the diagnostic challenges in pediatric populations. The meeting also addressed the integration of behavioral therapies, the role of the microbiome, and the application of artificial intelligence in reflux diagnostics. Collectively, these insights underscore a shift toward precision medicine in reflux disease, emphasizing individualized diagnostic strategies and tailored therapeutic approaches to improve patient outcomes.

Aging is a major risk factor for increased morbidity and mortality following acute respiratory virus infections. To elucidate the immune determinants underlying viral pathogenesis and delayed lung repair in the aged lung, a comprehensive time-course study was conducted. Single-cell RNA sequencing (scRNAseq) and high-dimensional flow cytometry were utilized to compare lungs from young and aged mice infected with influenza A virus (IAV). Aged hosts displayed diminished alveolar macrophage (AM) and dendritic cell (DC) but elevated monocyte-derived macrophage (MoM) and interstitial macrophage (IM) presence following infection. Additionally, enhanced accumulation of adaptive immune cells, including CD4+ tissue-resident helper (TRH) cells, CD8+ tissue-resident memory (TRM) cells, and a B cell subset resembling age-associated B cells, was observed in the memory phase. Pathway analysis revealed that elevated type I and II interferon (IFNα/γ) signaling, especially in MoM/IM subsets, distinguished the aged hosts from the young. Inhibition of IFNα/γ signaling after viral clearance improved long-term respiratory outcomes and reduced both IM and TRH populations in aged mice. These findings highlight the pivotal role of IFNα/γ signaling, likely within MoM/IM subsets, in driving the exuberant persistence of adaptive immune cells and chronic immunopathology in the aged lung following acute viral infection.

Background and Objectives: Genitourinary syndrome of menopause (GSM), previously known as vulvovaginal atrophy, is a chronic, progressive hypoestrogenic condition affecting vulvovaginal, urinary and sexual health in women. Common symptoms include vaginal dryness, itching, dyspareunia, urinary urgency and recurrent urinary tract infections (UTIs). Despite the high prevalence, GSM is underdiagnosed and undertreated, thereby negatively impacting women’s quality of life. To illustrate the practical aspects of GSM diagnosis and provide evidence-based management, we present a case-based narrative review synthesizing recently published, high-quality evidence. Materials and Methods: Evidence was drawn from multiple sources through targeted searches of databases, and included the 2025 AUA/SUFU/AUGS guideline (AUA), the 2024 NICE network meta-analyses (NICE), a 2025 systematic review/meta-analysis in breast-cancer survivors, the 2020 Menopause Society GSM Position Statement, the 2018 NAMS/ISSWSH breast cancer consensus, several primary source citations and other high quality peer-reviewed publications. Results: Five illustrative composite case vignettes of GSM are presented to highlight the evaluation strategy and evidence-supported treatment choices. Nonhormonal options are the first line treatments for mild GSM symptoms, either with or without the addition of vaginal estrogen therapy. For moderate to severe GSM, low-dose vaginal estrogen, vaginal DHEA, and ospemifene are all effective FDA-approved options. In breast cancer survivors, individualized decisions with oncology input are warranted. Maximal caution and a shared decision-making approach is required for women using Aromatase Inhibitors (AIs) for breast cancer risk reduction when choosing treatments for GSM. Conclusions: Treating GSM improves vaginal, sexual and urinary outcomes and quality of life of women. Clinicians need to proactively screen for GSM and offer evidence-based treatment options. The treatment decisions in breast cancer survivors are nuanced, requiring a shared-decision approach.

Purpose: With the increasing prevalence of sleeve gastrectomy, complications and insufficient weight loss have become more common, making conversion to Roux-en-Y gastric bypass (RYGB) a frequent revisional approach. Given the higher risk of revisional surgery, we aimed to compare primary versus conversion RYGB surgery and assess whether robotic assistance impacts outcomes. Method: This retrospective study included 378 patients after 2:1 propensity score matching based on demographic and clinical characteristics, comparing primary Roux-en-Y gastric bypass (P-RYGB) with sleeve gastrectomy–to–Roux-en-Y gastric bypass (SG-RYGB). The matched cohort included both robotic and laparoscopic cases performed at a single tertiary center between 2012 and 2024. A secondary 2:1 matched sub-analysis of robotic cases ( n = 297) evaluated whether robotic assistance reduced differences between primary and revisional surgery. Weight-loss outcomes were assessed at 6 and 12 months in the full cohort, with an additional sub-analysis limited to SG-RYGB performed for weight-loss indications. Results: In the full cohort ( n = 378), SG-RYGB was associated with longer operative time, greater blood loss ( P < .001), longer hospital stay ( P = .04), and higher late complication rates ( P = .04). In the robotic-only matched analysis ( n = 297), differences in operative time and blood loss were no longer significant, and early and late outcomes were comparable, although length of stay still remained longer for SG-RYGB ( P = .05). Among patients undergoing SG-RYGB for weight loss purposes only, total body weight loss percentage reached 16.5% ± 6.6% at 6 months and 20.4% ± 7.1% at 12 months but remained lower than that observed in the P-RYGB group ( P < .001). Conclusion: SG-RYGB conversion demonstrated favorable outcomes and meaningful weight loss. Robotic assistance was associated with improved operative time, reduced blood loss, and fewer late complications in the SG-RYGB group, further narrowing differences with P-RYGB, supporting its role in complex revisional bariatric surgery at high-volume centers.

Bruton tyrosine kinase inhibitors (BTKis) and BCL2 inhibitor (BCL2i)–containing regimens significantly improve survival outcomes in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Results from randomized clinical trials have demonstrated that time-limited treatment with BCL2i-containing regimens resulted in higher rates of undetectable measurable residual disease (uMRD) than BTKi monotherapy or chemoimmunotherapy (CIT). Pirtobrutinib (a noncovalent BTKi) and lisocabtagene maraleucel (CD19-directed CAR T-cell therapy) are newer options for relapsed or refractory disease after prior therapy with BTKi and BCL2i-contining regimens. Histologic transformation of CLL/SLL to diffuse large B-cell lymphoma (Richter transformation) is associated with a poor prognosis. Molecular analysis to determine whether there is clonal relationship between CLL/SLL and transformed diffuse large B-cell lymphoma is useful to select an appropriate treatment option. These NCCN Guideline Insights highlight significant updates to the NCCN Guidelines for the treatment of CLL/SLL and Richter transformation.

Background: NCCN publishes evidence-based guidelines across the cancer care continuum that are commonly used as the standard for clinical management and policy in cancer care. Our study aimed to assess the content of survivorship recommendations within disease-based NCCN Guidelines. Methods: In January 2024, we downloaded 64 disease-based guidelines from the NCCN website; 10 were excluded. The remaining 54 guidelines were reviewed for survivorship-focused content. Content of the guidelines was systematically categorized across domains of the Quality of Cancer Survivorship Care Framework, and the level of detail was rated as not addressed, briefly addressed, mostly addressed, or fully addressed. Guidelines were re-reviewed for updates in April 2025. Results: Of 54 guidelines reviewed in 2025, 16 (30%) included a dedicated survivorship section with focused content, although sections, titles, and formats varied. Other guidelines included survivorship recommendations in algorithms and/or discussion sections. A total of 18 guidelines (33%) had neither a dedicated section nor reference to the NCCN Survivorship Guidelines. Guidelines with a dedicated section, as well as those referencing the NCCN Survivorship Guidelines (65%), generally provided more detailed survivorship content. Across all guidelines, the surveillance for recurrences/new cancers domain was most commonly included (96%) and typically the most detailed. Information on physical (81%) and psychosocial (72%) effects and health promotion (65%) was often included, but the level of detail varied. Chronic disease management (31%) was seldomly included. Information on care coordination/communication and patient education was present in 50% of the guidelines. Compared with the guidelines reviewed in 2024, the 2025 updates had limited expansion of survivorship content. Conclusions: Cancer survivorship content is inconsistently presented across disease-specific NCCN Guidelines. As these guidelines evolve, there is an opportunity to tailor, expand, and standardize the recommendations, making them easier to find by clearly labeling and integrating them within each guideline to improve accessibility and better support clinicians in delivering patient-centered care.

BACKGROUND: Morel-Lavallée lesions (MLLs) are closed degloving injuries that occur throughout the body and present treatment challenges due to their rarity and variability in management. We aimed to compare characteristics and outcomes for MLL patients undergoing early (less than 48 hours) vs late (more than 48 hours) surgical intervention, hypothesizing decreased length of stay (LOS) with early intervention. STUDY DESIGN: Fifteen centers participated in this prospective observational study, including all adult patients who sustained a MLL and underwent surgery. No patients were excluded. Bivariate comparisons for early vs late intervention cohorts were performed. RESULTS: Of 150 MLL patients, 101 (67.3%) underwent early intervention. Both cohorts had comparable ages, BMI, vitals, Charlson Comorbidity Index, and injury severity scores (all p > 0.05). However, early intervention patients more commonly had abdominal (37% vs 6.3%, p < 0.001) MLLs, whereas late intervention patients more often had hip (16.7% vs 3.0%, p = 0.01) and thigh (41.7% vs 22%, p = 0.03) MLLs. Early patients had shorter ICU LOS (2 vs 5, p = 0.003) but statistically similar hospital LOS (12 vs 20, p = 0.06). There was no difference in wound-related complications (19.8% vs 24.5%, p = 0.51) or mean number of additional surgeries (p = 0.41) between cohorts. CONCLUSIONS: Over two-thirds of MLL patients underwent early operation. These patients had decreased ICU LOS and a statistically similar albeit clinically shorter overall LOS, despite similar demographics, comorbidities, injury severity, and number of additional surgeries. Therefore, early operation appears beneficial and should be pursued in MLL patients when clinically indicated and feasible.

The rapid adoption of telemedicine has transformed healthcare delivery in the US, enhancing access and communication for surgical patients across wide geographic areas. However, a critical challenge persists: the need to define and standardize quality metrics specifically for telemedicine in surgery. Existing studies suggest that telemedicine can yield equivalent or improved outcomes compared with in-person visits. Nevertheless, literature remains limited in evaluating patient satisfaction, cost-effectiveness, and diagnostic accuracy. Through expert consensus within the American College of Surgeons Board of Governors Telehealth Pillar, we propose a structured framework for defining and implementing quality metrics for surgical telemedicine. This is based on the Donabedian model, addressing structure, process, and outcome, while also considering the distinct phases of surgical care: preoperative, intraoperative, and postoperative. This framework identifies unique domains of telemedicine in surgical care, emphasizing hospital and organizational structure, patient and provider readiness, and policy alignment. A comparative analysis with existing AHRQ and WHO frameworks highlights gaps in surgical applicability. Finally, we propose an implementation roadmap prioritizing immediate, feasible metrics while identifying areas for future validation. Collaboration among researchers, clinicians, and policymakers will be essential to establish these metrics and ensure that telemedicine delivers on its potential to improve surgical care delivery while addressing disparities in access and outcomes.
