BACKGROUND AND AIMS/OBJECTIVE:Endoscopic submucosal dissection (ESD) is preferred over endoscopic mucosal resection (EMR) for resection of colon cancer with suspected superficial invasion. Data on appropriate utilization of ESD such as rates of cancer and non-curative resection (NCR) are under-reported. METHODS:Retrospective multicenter study of 547 consecutive colonic lesions undergoing ESD was performed. Outcomes were rates of cancer, NCR, surgery and predictors of NCR. RESULTS:Of all lesions, histopathology demonstrated cancer in 12% (n = 66). Overall, NCR was seen in 59.1% (n = 39) patients and 24.6% (n = 135) lesions contained high-grade dysplasia. For NCR, patients underwent surgery in 7.6% (n = 3) and adverse events were observed in 8.8% (n = 48). CONCLUSIONS:In our large multicenter Western cohort, the pathology was found to be benign in most of the colon ESDs and there was high NCR for resected lesions with cancer. The overall surgery rate, however, remained low. This study highlights the need to refine lesion selection criteria while continuing to optimize ESD technique to match the efficiency and safety of EMR.

Sjögren's disease (SjD) exemplifies the intricate relationship between oral health and overall systemic wellness. Characterized by autoimmune-mediated destruction of exocrine glands, it commonly manifests as xerostomia (dry mouth) and keratoconjunctivitis sicca (dry eyes), yet its reach extends well beyond the salivary and lacrimal glands to involve musculoskeletal, renal, pulmonary, and neurological systems. Insights from national patient surveys underscore considerable unmet needs in SjD management, emphasizing the importance of early recognition of oral health challenges. Concurrently, advances in clinical and translational research deepen our understanding of SjD's underlying mechanisms, revealing novel diagnostic and therapeutic strategies that target immunological pathways, foster glandular regeneration, and may alter disease progression. By providing a cohesive synthesis of state-of-the-art evidence, this review aims to expand clinicians' and researchers' understanding of SjD pathogenesis, address new research areas and key gaps, highlight the critical role of medical partnerships in addressing both systemic and oral manifestations, and advance patient-centered strategies to improve detection, treatment, and long-term disease management of this multifaceted autoimmune disorder. We discuss immune-mediated tissue damage, the potential of emerging biomarkers, and innovative treatments, including biologic agents and regenerative techniques. Patient perspectives further illuminate the daily challenges posed by SjD, underscoring the need for interdisciplinary care models that integrate oral medicine, rheumatology, and other medical specialties. Taken together, these insights underscore the pressing need for heightened awareness and collaborative approaches to pave the way for precision medicine interventions that can transform current management paradigms and ultimately improve the lives of individuals affected by Sjögren's disease.

OBJECTIVE:Induction of labor (IOL) and hospitalist coverage is becoming more common. While hospitalist coverage has been associated with improved maternal outcomes and lower cesarean delivery rates, its impact on IOL remains unclear. The objective of this study was to compare the induction time to vaginal delivery across three obstetric coverage models: hospitalists, faculty generalists, and private practice generalists. STUDY DESIGN/METHODS:This single-site retrospective cohort study analyzed singleton, term (≥39 weeks), vertex patients undergoing induction of labor at NYU Langone Hospital- Long Island from January 1 to September 30, 2022. Hospitalists at this institution managed high-risk obstetric patients including those under maternal-fetal medicine care, resident clinic, and unregistered patients who presented to labor and delivery, along with serving as labor and delivery safety officer on the labor floor. Faculty and private practice generalists managed their respective groups. Outcomes included induction time to vaginal delivery, mode of delivery, induction methods, and maternal and neonatal complications. Statistical analyses included chi-square, ANOVA, and multivariable linear regression. A p-value <0.05 was statistically significant. RESULTS:Among 403 patients, 92 (22.8%) were managed by hospitalists, 115 (28.5%) by faculty, and 196 (48.6%) by private generalists. Median (IQR) induction-to-delivery times were similar across groups-hospitalists 20.5 (15.3-27.5) h, faculty 23.4 (16.5-31.1) h, and private 19.7 (14.1-25.6) h (p = 0.004). However, when limited to vaginal deliveries, no significant difference was observed in induction-to-vaginal-delivery time (p = 0.17). Private generalists had the shortest induction-to-cesarean time and time to membrane rupture leading to cesarean. There were no differences in intrapartum complications. Hospitalists had more NICU admissions after vaginal delivery, mostly unrelated to labor. CONCLUSION/CONCLUSIONS:Induction-to-vaginal delivery times and complication rates were similar across coverage models, but differences in NICU admissions and cesarean delivery times highlight care variations. Collaboration and evidence based standardized induction protocols may optimize outcomes across coverage models.

We compared outcomes of patients ≥ 70 years old undergoing allogeneic stem cell transplantation (alloSCT) with graft-vs-host disease (GvHD) prophylaxis regimens either including post-transplant cyclophosphamide (PTCy) or without cyclophosphamide (non-Cy). The primary endpoint was GvHD-free, relapse-free survival (GRFS) at one and five years; secondary endpoints included clinically significant acute (grade III-IV) and chronic (extensive) GvHD, relapse, overall survival (OS), and non-relapse mortality (NRM). Among 61 patients, 41 received PTCy and 20 received non-Cy prophylaxis. Unrelated donors accounted for 80 % of allografts; all non-Cy patients had 10/10 HLA matches, while PTCy patients had 64 % matched, 29 % haploidentical, and 7 % mismatched unrelated donors. Acute GvHD occurred in 5 % of PTCy vs 15 % of non-Cy patients (p = ns). One-year chronic GvHD incidence was lower with PTCy (12 % vs 30 %, p = 0.03). One-year GRFS was similar (34 % PTCy, 35 % non-Cy; p = ns). At five years, OS was 20 % vs 30 % and GRFS 21 % vs 15 % for PTCy and non-Cy, respectively (p = ns). We observed similar outcomes among patients receiving GvHD prophylaxis with PTCy compared to non-Cy. Importantly, non-Cy patients had HLA-matched donors, whereas mismatched donors were possible for the PTCy group. In this way, PTCy seems to have equalized outcomes for fully matched and mismatched alloSCT by yielding similar one and five-year GRFS. We also found no significant difference in relapse rate, NRM, OS, and five-year GRFS between patients aged 70-74 and ages 75 + , showing that numerical age should not be a contraindication to alloSCT.

BACKGROUND:Porcine genome editing has revolutionized xenotransplantation, recently enabling the first pig-to-human heart xenotransplants. However, the xeno-immune response in heart xenografts remains largely unexplored. This study aimed to precisely characterize the xeno-immune response and injury in two heart xenografts, transplanted from 10-gene-edited pigs into brain-dead human recipients. METHODS:We analyzed xenograft biopsies at 66-hour post-reperfusion using a multimodal phenotyping approach combining: morphological evaluation, immunophenotyping, ultrastructural assessment, automated quantification of multiplex immunofluorescence staining and gene expression profiling. Xenografts before implantation and wild-type pig hearts with and without ischemia reperfusion injury and brain death were used as controls. RESULTS:Both xenografts showed evidence of endothelial activation and mild microvascular inflammation without capillary C4d deposition. Immune infiltrates were mainly composed of CD15+ and CD68+ innate immune cells. Ultrastructural assessment showed endothelial swelling with occasional intravascular leucocytes. Deep-learning based automated multiplex immunofluorescence analysis confirmed that microvascular inflammation was primarily associated with CD15+ and CD68+ innate immune cells. Both xenografts showed increased expression of genes and pathways associated with monocyte/macrophage activation, neutrophil activation, interferon-gamma response, natural killer cell burden, endothelial activation, apoptosis and injury repair. This phenotype was absent in all control pig hearts, independently from ischemia reperfusion injury and brain death. CONCLUSIONS:Multimodal phenotyping of pig-to-human heart xenografts revealed early signs of xeno-immune response, characterized by mild innate microvascular inflammation, endothelial activation, and molecular signature characteristic of antibody-mediated rejection. Developing such precision diagnostic system could improve graft monitoring in future clinical settings.

OBJECTIVES/OBJECTIVE:Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision-making process, we developed an evidence-based clinical practice guideline for the evaluation and management of peripheral nervous system manifestations in patients with Sjögren's disease. METHODS:A Topic Review Group (TRG), comprised of experts in rheumatology, neurology, and guideline methodology, developed Patient, Intervention, Comparison, and Outcome (PICO) questions and conducted a systematic review to identify current best evidence on management of PNS manifestations of Sjögren's disease. PubMed and Embase were searched for evidence published up to July 22, 2025. Literature screening, data extraction, and critical appraisal were performed in duplicate. Six case series, one retrospective cohort, and two prospective cohort studies lacking a comparison group met the inclusion criteria. RESULTS:We developed an aligned nomenclature of PNS terms that can be used across disciplines, 31 good practices for evaluation of suspected PNS manifestations, and 20 evidence-based treatment recommendations, the latter of which were rated as conditional or strong based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Due to the scarcity of high-level evidence, this guideline predominantly derives from expert opinion. CONCLUSION/CONCLUSIONS:This clinical practice guideline on PNS manifestations of Sjögren's disease provides clinicians a rigorous, evidence-based resource, developed through an expert consensus-based process, for the assessment, diagnosis, and treatment of peripheral neuropathy in Sjögren's patients. Recommendations were rated as strong when the benefits significantly outweighed potential harms, creating a scenario in which the majority of patients would prefer the advised action.
