Summary Oral ovalbumin administration prevents epicutaneously‐induced egg allergy by suppressing Tfh and B cells and IgE. This prophylactic oral ovalbumin abolishes antigen‐specific IL‐4 and IL‐13 production in skin‐draining lymph nodes.

Background Individuals with schizophrenia spectrum disorders are at increased risk of cardiometabolic complications, largely due to antipsychotic-associated metabolic effects. Effective management strategies remain limited. Semaglutide, a glucagon-like peptide-1 receptor agonist, has shown metabolic benefits in the general population, but its role in this population remains unclear. Objective To evaluate the efficacy and safety of semaglutide compared with placebo in individuals with schizophrenia spectrum disorders receiving antipsychotic therapy and experiencing metabolic abnormalities. Design Systematic review and meta-analysis of randomized controlled trials. Data Sources and Methods: A systematic review and meta-analysis was conducted following PRISMA guidelines. PubMed, Cochrane Library, Embase, and ScienceDirect were searched from inception to February 2026. Randomized controlled trials comparing semaglutide with placebo were included. The longest follow-up time point from each study was used for pooled analysis. Mean differences (MD) and odds ratios (OR) with 95% confidence intervals (CIs) were calculated using RevMan 5.4. The certainty of evidence for critical outcomes was assessed using the GRADE framework. Results Three randomized controlled trials (n = 258) were included. Semaglutide was associated with reductions in body weight (MD: -11.01 kg), BMI (MD: -3.63 kg/m 2 ), and waist circumference (MD: -6.33 cm). Improvements were also observed in body composition. No significant differences were found in lipid or glycemic parameters except HbA1c which showed a significant reduction. Psychiatric outcomes remained unchanged. Gastrointestinal adverse particularly nausea and vomiting events were more frequent with semaglutide. Conclusion Semaglutide appears to improve anthropometric outcomes without worsening psychiatric symptoms in individuals receiving antipsychotic therapy. However, evidence is limited, and larger, long-term trials are required. According to the GRADE framework, the certainty of evidence ranged from moderate for key anthropometric and safety outcomes to low or very low for several metabolic and psychiatric outcomes, highlighting the need for larger, long-term randomized trials.

ABSTRACT Background and Aim Significant health disparities persist in alcohol‐associated liver disease (ALD), largely driven by social determinants of health (SDOH). However, the influence of neighbourhood‐level SDOH on ALD outcomes remains underexplored. In this study, we aimed to evaluate how neighbourhood‐level SDOH are associated with disease burden, comorbid conditions, and mortality in individuals with ALD. Methods We conducted a retrospective cohort study of patients with ALD in the Banner Health System, representing hospitals across Arizona, California, Nevada, Wyoming and Colorado, from January 2012 to October 2024 using ICD codes. Neighbourhood‐level SDOH were quantified using the Social Deprivation Index (SDI). Patients were stratified into quartiles based on SDI score, with Quartile 4 representing the most socioeconomically disadvantaged neighbourhoods. Primary outcomes included incidence of mortality, cirrhosis, major adverse liver outcome (MALO), Type 2 diabetes mellitus, any cancer, and major adverse cardiovascular events (MACE). A multivariable competing risk analysis was performed adjusting for age, sex, race/ethnicity, insurance type, primary language, smoking status, Type 2 diabetes mellitus, hypertension, hyperlipidemia, aspirin use, statin use, alcohol use disorder and a composite mental‐health/substance‐use disorder variable encompassing depression, anxiety disorders, post‐traumatic stress disorder, bipolar disorder, schizophrenia, and non‐alcohol substance use disorders. Results Among 11,394 patients with ALD and available SDI data, 6747 had ≥ 365 days of follow‐up. The average age was 51 years and 65.6% were female; 68.8% were non‐Hispanic White, 19.7% Hispanic, 5.9% Native American/Alaskan Native (NA), 3.2% Black, and 0.4% Asian/Pacific Islanders. Patients residing in the most disadvantaged neighbourhoods (Quartile 4) were significantly younger, more likely to be female, had a higher median BMI, and more frequently reported a non‐English primary language compared with those in the least disadvantaged areas (Quartile 1). Patients in the most deprived neighbourhoods were more likely to be Hispanic, Black, or Native American/Alaska Native and to be uninsured or on Medicaid, whereas those in the least disadvantaged neighbourhoods predominantly had private insurance. Individuals in Quartile 4 had increased mortality (adjusted hazard ratio [aHR]: 1.48, 95% Confidence Interval [CI]: 1.09–2.01) compared with individuals in Quartile 1. Conclusions In this large and demographically diverse ALD cohort, residing in socioeconomically disadvantaged neighbourhoods was associated with increased risk of mortality. These findings support the need for contextually tailored clinical interventions and broader treatment strategies that target upstream sociocultural and environmental factors that are associated with health outcomes. Addressing neighbourhood‐level SDOH through community engagement, policy reform, and cross‐sector partnerships to improve collaborative care efforts is needed to reduce health disparities in ALD.

ABSTRACT Introduction Sustaining interventions implemented as part of pragmatic clinical trials requires proactive planning, but how to approach this process remains understudied. The Non‐pharmacological Options in Hospital‐based and Rehabilitation pain Management stepped‐wedge cluster‐randomized pragmatic trial tested an electronic health record‐based educational bundle (known as the Healing After Surgery [HAS] initiative) that encouraged the incorporation of non‐pharmacological pain care in perioperative pain management. The HAS initiative was implemented in multiple surgical practices and hospital sites. One year prior to trial completion, a sustainment committee was established to support the transition of intervention components to clinical ownership and to support posttrial sustainment of the HAS initiative. Methods We reviewed meeting minutes from biweekly sustainment committee meetings and conducted debriefing sessions with committee members (informed by the Clinical Sustainability Assessment Tool) to identify sustainment strategies and challenges, which were then organized into meaningful themes. Results The following six themes emerged from meeting minutes and debriefings: (1) automation of low‐touch components, (2) reliance on internal champions, (3) intentional handoff communication, (4) institutional attention, (5) relaxed fidelity, and (6) continuous evaluation. Together, they highlight the importance of early, structured planning and adaptable implementation strategies. Conclusions Sustainment of the HAS initiative required extensive communication, adaptation, and stakeholder engagement across diverse institutional contexts. Proactive sustainment planning during trial design may help ensure interventions are successfully integrated into routine clinical practice posttrial.

Abstract The use of natural killer (NK) cells for the treatment of solid tumors such as cholangiocarcinoma has been hindered by challenges related to cell production, persistence and trafficking, as well as by reduced efficacy within an immunosuppressive tumor microenvironment. Antitumor immunity can be reduced by the interaction of NK cell expressed programmed cell death protein 1 (PD1) with ligands on tumor and other cells within the tumor microenvironment. The antitumor effect of NK cells is enhanced in cells engineered to express a truncated PD1 without an intracellular domain. The cytolytic potential and therapeutic efficacy of extracellular vesicles (EVs) derived from human NK cells expressing truncated PD1 was evaluated as a cell-free therapeutic to overcome some limitations faced by cell therapies. We demonstrate the feasibility of efficient expansion, production and isolation of therapeutic vesicles from human NK cell lines and from engineered NK92 cells expressing truncated PD1. The cytotoxic efficacy of these therapeutic vesicles was validated in both monolayer tumor cell cultures and in multicellular tumor spheroids. Concomitant administration of gemcitabine upregulated NKG2D ligands on tumor cells and increased susceptibility to NK cell and to NK cell derived EV mediated killing. These findings position engineered NK cell derived-EVs as a scalable and promising cell-free immunotherapeutic for cholangiocarcinoma.

Introduction: Multitarget stool DNA (mt-sDNA) is a sensitive stool-based test for colorectal cancer (CRC) screening. Limited referral-center data suggest low rates of incident aerodigestive cancers after a positive mt-sDNA and negative colonoscopy; community-based outcomes are unknown. Methods: Retrospective cohort study of adults referred for colonoscopy after positive mt-sDNA in a large community practice (2017–2021). Among patients with negative colonoscopy, we manually recorded post-colonoscopy recommendations, findings if additional colonoscopies had been performed, aerodigestive cancer diagnosis, and last clinical follow-up. Observed cancer incidence was compared with Surveillance, Epidemiology, and End Results (SEER) data. Results: Of 1,176 patients completing colonoscopy after positive mt-sDNA, 328 (28%) had negative findings. Median cohort age was 67 (IQR 59-72) years. Colonoscopy was performed at a median of 53 days after mt-sDNA sample collection. Post-colonoscopy recommendations aligned with multi-society task force (MSTF) guidelines in 59% of patients. Thirty-two patients underwent repeat colonoscopy with a median of 3.5 (1.9-4.4) years later; 2 (6.3%) had advanced serrated lesions, and no CRC was detected. Median clinical follow-up was 4.4 (3.4-5.6) years. Seven patients developed aerodigestive cancers (2 pancreatic, 5 lung), consistent with expected age- and sex-adjusted SEER incidence (n=7.62) (p=0.823). Discussion: In this community cohort, when a positive mt-sDNA was followed by negative colonoscopy, rates of subsequent advanced colorectal neoplasia and aerodigestive cancer were low. Most patients received recommendations for subsequent colonoscopy that were consistent with MSTF guidelines. Findings further support the current MSTF recommendation of no additional evaluation for extra-colonic malignancy in asymptomatic patients after high quality follow-up colonoscopy.

Transvaginal oocyte retrieval (TVOR) is typically performed under ambulatory intravenous (IV) sedation with preservation of spontaneous ventilation. We retrospectively identified five medically complex patients who received remimazolam as part of individualized anesthetic management for TVOR at a tertiary academic center. Comorbidities included cardiomyopathy, Fontan physiology, pheochromocytoma, difficult airway, and renal transplantation. Spontaneous ventilation was preserved in all cases without airway intervention. Two patients required intermittent phenylephrine, and one required flumazenil for delayed emergence. Median time from operating room exit to discharge readiness was 128 minutes (range 39–149). These cases illustrate clinical scenarios in which remimazolam may support individualized anesthetic strategies for medically complex patients undergoing TVOR.
