Introduction: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease without approved medical therapies. We examined the efficacy and safety of oral vancomycin (OV) in those with PSC. Methods: In this phase 3, 18-month, double-blind, placebo-controlled trial, we randomly assigned adults with PSC and a serum alkaline phosphatase (SAP) greater than 1.5 times the upper limit of normal to placebo or oral vancomycin (OV) with dosages ranging from 125-375 mg four times daily pending biochemical response. The primary endpoint was normalization of SAP. Results: Of the 82 patients who underwent randomization, 73 individuals had at least one outcome assessment. Individuals who withdrew early were less likely to rate their baseline health as excellent or very good (23.4% vs 54.5%, p<0.01) despite having similar PSC prognostic features to those who completed the study. SAP normalization rates were similar (5% placebo, 6.7% OV, p=1.00) after 18 months. Those who received OV had greater reduction in SAP (+1.2% placebo, -21.9% OV, p=0.03). There were no differences in the changes in either the Mayo PSC risk score (-0.1 placebo, -0.1 OV, p=0.88) or liver stiffness values (+0.1 kPa placebo, -4.0 kPa OV, p=0.15). Discoloration of the teeth and tongue was the most common side effect of OV (17.5%). Conclusions: OV was not associated with clinically significant reductions in markers of PSC disease severity. Impairments in quality of life may influence patient retention in clinical trials.

Objectives To compare patients’ perception of their degree of subglottic stenosis to their endoscopic exam findings, Clinical Dyspnea Questionnaire, and peak flow results. Study Design Prospective Multi-Institutional. Setting Tertiary Care Clinic. Methods A study of 50 patients comparing patients’ perception of their degree of subglottic stenosis to their endoscopic exam findings. All patients filled out a Clinical Dyspnea Questionnaire and a 10-point scale reflecting their perceived degree of stenosis in 10% intervals. Surgeons filled out the same scale based on measurements from the patients’ exam. Accuracy was defined as +/-1 on a 10-point scale. Pulmonary function testing, number of dilation procedures undergone, cause of stenosis, and demographic information were collected. Results Data complete for 49/50 patients. 48 (98%) were female, 47 (97.9%) Caucasian, 44 (89.8%) had idiopathic subglottic stenosis, and 28 (58.3%) had Grade I subglottic stenosis on the Cotton-Meyer scale. Spearman correlation coefficient was 0.67 indicating moderate correlation overall but 0.88, or high correlation, for those with normal Body Mass Index. Increased Dyspnea Index scores and higher Body Mass Index were correlated with decreased accuracy. Number of previous procedures was not correlated with accuracy. Higher Body Mass Index was correlated with increased dyspnea and lower peak flow volume. Conclusion Patients with normal Body Mass Index have strong predictive accuracy regarding their degree of subglottic stenosis. Better dyspnea scores were correlated with improved accuracy. There is no standard consensus on subglottic stenosis patient follow up. Prior studies have looked at using peak flow meters and validated questionnaires to monitor symptoms.

INTRODUCTION: Online patient education materials are essential in improving access to and understanding of clinical information. Artificial intelligence (AI), specifically ChatGPT, offers a novel way to synthesize complex information and is increasingly being used for patient education, including in obstetrics and gynecology. This study compares the understandability and actionability of patient education materials about hysterectomy and uterine fibroids generated by ChatGPT with those published by the American College of Obstetricians & Gynecologists (ACOG). METHODS: In a randomized cross-sectional study, participants were allocated to one of four groups: ACOG–Fibroids, ChatGPT–Fibroids, ACOG–Hysterectomy, or ChatGPT–Hysterectomy. The ACOG groups reviewed the corresponding ACOG FAQ webpage, while the ChatGPT groups reviewed responses generated by ChatGPT to the same FAQs. Participants then completed demographic questions and the Patient Education Materials Assessment Tool (PEMAT). The primary outcome was the equivalence of PEMAT scores between ACOG and ChatGPT. RESULTS: Equivalence was not demonstrated between ChatGPT and ACOG for either topic. For fibroid material, ACOG was rated higher on both understandability (86.3 versus 82.6 points, P =.039) and actionability (65.4 versus 53.2 points, P =.003) on superiority testing. For hysterectomy content, no significant difference was observed. No interaction was found between material type and either education level or personal history of fibroids/hysterectomy. CONCLUSIONS/IMPLICATIONS: PEMAT scores for ACOG were superior to ChatGPT for fibroid content, but neither equivalent nor superior for hysterectomy content. While ChatGPT offers a responsive, iterative source of information, its understandability and actionability may depend on topic-specific factors, highlighting both the promise and limitations of AI for patient education.

Critically ill patients frequently require intrahospital transport (IHT) to diagnostic exams or procedures and must remain connected to life-sustaining medical lines. During IHT, the risk of tangled medical lines is unavoidable. The idea for a novel medical line securement device was inspired by a patient transport nurse due to frustrations and workflow inefficiencies managing tangled medical lines. The study aim was to explore the correlation between the utilization of a single-use securement device to manual or accidental disconnections of medical lines during IHT, and nurses’ perception of efficiency, compared to the current practice of no utilization of a securement device. In 2019, a randomized, descriptive, correlational study was conducted on 142 progressive and intensive care hospitalized patients. Study coordinators measured the number of times either IV lines or monitor cords were accidentally or manually disconnected to detangle during or after transportation and the perception of transport efficiency. Results revealed fewer manual disconnections among intervention group compared to the control. Nurses’ perception regarding the efficiency between the intervention and control group was statistically significant when the device was utilized to secure the lines and cords during transport. Nurses reported much higher satisfaction rates of transport efficiency when the device was used. This finding showed the device’s utility for improving nurse satisfaction during IHT of critically ill patients. Utilization of the medical line securement device may be generalizable across other healthcare settings and disciplines where the complexity of medical lines may exist.

Abstract Introduction Combat casualty care requires standardized proficiency criteria to ensure readiness in austere environments, yet gaps persist in defining performance thresholds for critical trauma skills. The Combat Medical Skills Sustainment Consortium (CMSSC), a novel military-civilian collaboration, aimed to validate competency thresholds for 21 Department of Defense-identified trauma skills. Materials and Methods A prospective cohort study (2022-2025) enrolled 1,495 military and civilian personnel across five academic centers, stratified by experience (novice, intermediate, expert). Skills, including cricothyroidotomy, whole blood transfusion, and ultrasound-guided vascular access, were assessed using validated checklists in Role 2-congruent simulations. Statistical analysis compared checklist performance against participant experience with a priori checklist scores estimated at 40% (novices) and 90% (experts). Results Competency thresholds were established, ranging from 77% (mechanical ventilation) to 100% (handoff). Experts achieved 85%-98% proficiency across most skills, with novices at 34%-97%. A ceiling effect was observed for less complex skills consistent with the power law of practice. Conclusion The Combat Medical Skills Sustainment Consortium validated standardized assessment tools, with potential to address readiness gaps through military-civilian synergy. Findings support consortium-guided curriculum development and highlight the need for longitudinal skill decay studies. Impact This study sets a benchmark for trauma care skills assessment, facilitating rapid adoption across military and civilian settings.

Abstract Background: The International Consensus Classification (ICC) for systemic mastocytosis (SM) recognizes mast cell leukemia (MCL) and SM with associated myeloid neoplasm (SM-AMN) as distinct categories of advanced SM (SM-Adv; Arber et al. Blood 2022;140:1200). Contemporary risk models in SM, including the Mayo Alliance Prognostic System (MAPS), do not account for the prognostic heterogeneity among ICC-defined SM-Adv subcategories. Methods: Mayo Clinic databases were utilized to access patient information. Diagnoses of SM and its morphological subcategories were confirmed through clinical evaluations and review of BM pathology. Diagnostic criteria were retrospectively fitted to be consistent with those of the ICC (Arber et al. Blood 2022;140:1200); diagnosis of MCL required the presence of immature cytomorphology of mast cells and only myeloid neoplasms were listed under the category of SM-AMN.Next-generation sequencing and cytogenetic studies was performed in a subset of the study patients according to previously described methodologies. Statistical analyses were conducted on clinical and laboratory data collected at the time of initial diagnosis while survival analysis was censored at the time of allogeneic stem cell transplant (ASCT). Results: A total of 910 Mayo Clinic patients with SM (median age 56 years, range 12-89; males 50%) were accessed in order to conduct a series of multivariable analyses (MVA) in search of independent risk factors for transplant-censored overall survival (OS). All patients were evaluable for assignment to specific ICC categories of SM: indolent (ISM; N=553), aggressive (ASM; N=114), SM-AMN (N=235), and MCL (N=8); the AMN components in SM-AMN included acute myeloid leukemia (N=18), chronic myelomonocytic leukemia (N=70), myelodysplastic syndromes (N=32), MDS/myeloproliferative overlap (N=81), myelofibrosis (N=7), polycythemia vera or essential thrombocythemia (PV/ET; N=19), and others (N=8). In addition, subsets of patients were evaluable for hemoglobin level (N= 865), white blood cell count (WBC; N=858), platelet count (N= 859), serum alkaline phosphatase (ALP; N=761), serum tryptase level (N=706), karyotype (N=574), and mutations (N=240). Median follow-up for living patients was 70 months (range, 0-520); during this time 346 (38%) deaths, 16 leukemic transformations, and 20 ASCTs were documented. ROC analysis-determined optimal cutoff levels for predicting OS included age at ≥60 years, platelet count &lt;150 x 109/L, tryptase level ≥100 ng/mL, WBC ≥10 x 109/L, hemoglobin below sex-adjusted lower limit of normal (anemia), and ALP &gt;210 U/L in women or &gt;170 U/L in men (increased). All except WBC ≥10 x 109/L retained significance during MVA that included ICC-specified SM categories: MCL (HR 74.8, 26.0-215.3; p&lt;0.01); SM-AMN (HR 3.9, 2.5-6.0; p&lt;0.01); ASM (HR 2.2, 1.4-3.5; p&lt;0.01); age ≥60 years (HR 3.3, 2.2-4.7; p&lt;0.01); platelets &lt;150 x 109/L (HR 2.8, 2.0-3.9; p&lt;0.01); tryptase ≥100 ng/mL (HR 2.1, 1.5-2.9; p&lt;0.01); anemia (HR 1.7, 1.1-2.4; p&lt;0.01); and increased ALP (HR1.5, 1.1-2.0; p=0.01). A subsequent HR-weighted risk model effectively delineated 5 risk levels ranging in median survivals from 11 months to 372 months (Figure 1). Figure 2 outlines complementary subtype-specific risk models; to that end, risk factors for ISM included age ≥60 years (HR 4.5, 2.5-7.9), tryptase ≥100 ng/mL (HR 3.5, 2.1-6.0); platelets &lt;150 x 109/L (HR 3.4, 1.5-7.9), and anemia (HR 2.4, 1.2-4.8); for ASM age ≥60 years (HR 2.3, 1.3-4.3), platelets &lt;150 x 109/L (HR 2.4, 1.4-4.0), and anemia (HR 2.0, 1.2-3.4); and for SM-AMN age ≥60 years (HR 2.9, 1.6-5.2), platelets &lt;150 x 109/L (HR 2.5, 1.6-3.9), and tryptase ≥100 ng/mL (HR 2.5, 1.6-3.9) [Figure 2]. In SM-AMN, additional prognostic relevance from subcategorization into PV/ET vs. all other types of AMN was appreciated (Figure 3; HR 4.0, 1.6-3.9) and incorporated into the risk model for SM-AMN (Figure 2). Abnormal karyotype (AK) and high risk mutations(HRM; ASXL1, SRSF2, RUNX1, NRAS)clustered withSM-AMN with AK and ASXL1MUT displaying independent prognostic relevance that was most apparent in SM-AMN. Conclusions : MAPS-R relies on the prognostic eminence of ICC-defined morphologic subcategories and allows for additional SM subtype-specific risk stratification. SM associated with ET or PV is a prognostically unique subcategory of SM-AMN and should be recognized as such in future classification schemes. SM-AMN must be thoroughly ruled out in the presence of AK or HRM.

Introduction Problematic alcohol use negatively impacts individuals, families and communities. While perceptions regarding alcohol use are likely vital to mitigating problematic alcohol use at the population level, little is known. Perceptions that demarcate normative versus problematic use may be relevant for interventions in communities with normative alcohol use. Our study explores ethnocentric perceptions of alcohol use in a community where alcohol use is historically integrated into its social fabric. Methods Mixed-methods study design using a culturally curated online survey with closed and open-ended responses assessed perceptions regarding alcohol use. Participants were members of the Kodava community: an affluent ethno-linguistic community in Southern India with an international presence. For Kodavas, alcohol consumption is normative and socially sanctioned. We studied perceptions of alcohol use among family members, including factors influencing its use and the impact of problematic alcohol drinking on immediate and extended family in three domains: health, finances and relationships. Results Of 711 total respondents, a small minority of 11.4% (n=81) stated that at least one immediate family member experienced negative impacts of alcohol use. Among respondents who reported on their extended family (n=639), 52.1% (n=333) endorsed at least one member experienced negative impacts. The integration of quantitative and qualitative data elucidates negative impacts of alcohol use within and at the intersections of health, relationships and finances. Conclusions First study to employ social media (WhatsApp) to survey a globally dispersed ethnic community on alcohol use impacts among family members. Interventions tailored to these perceptions, in culturally embedded communities, may improve outcomes. The framework and approach of this study can be replicated globally.

Introduction Despite growing evidence to characterise cancer-associated cognitive decline (CACD) in women with breast cancer, interventions to mitigate CACD are limited. Emerging evidence suggests aerobic exercise may enhance cognition after breast cancer diagnosis and treatment; yet, CACD remains an understudied outcome of exercise, and few high-quality studies have been conducted. In addition to knowledge gaps in effectiveness, the translation of exercise interventions to community settings remains challenging. The Breast cancer Reasoning and Activity INtervention (BRAIN) investigates the effectiveness of aerobic exercise training, delivered in a community-based setting, for improving cognitive function in women with breast cancer and gathers information on the implementation success of the intervention. Methods and analysis This Hybrid Type I effectiveness–implementation study is conducted at an academic medical centre in the southwestern United States in partnership with a non-profit, community health and wellness organisation. The study enrols 160 women diagnosed with stage I–IIIa breast cancer and within 3–36 months of treatment completion into a 1:1 randomised controlled trial. Individuals randomised to the exercise group receive a 6-month, individually tailored aerobic exercise programme delivered by exercise trainers employed at local community fitness centres. The programme is progressive in nature and designed to help participants achieve aerobic exercise levels consistent with guidelines for cancer survivors. Individuals randomise to the control group receive a 6-month health education control intervention delivered virtually by hospital-based health educators. Cognitive performance (primary), self-reported cognition, patient-reported outcomes, physical activity and cardiorespiratory fitness are measured at baseline, 6 months (postintervention) and 12 months (follow-up). Brain structure and function are measured via magnetic resonance imaging (MRI) at baseline and 6 months. Implementation outcomes are defined by the RE-AIM framework, which includes reach, effectiveness, adoption, implementation and maintenance. RE-AIM outcomes are measured at baseline, 6 months, 12 months and ongoing during the study. Ethics and dissemination This study was approved by the Mayo Clinic Institutional Review Board (#23-000020). All participants provide informed consent prior to participation. Findings will be disseminated to scientific, clinical and community audiences through manuscripts, presentations and newsletters. Trial registration number NCT04816006.

ABSTRACTThe current study includes 910 patients with systemic mastocytosis (SM) seen at the Mayo Clinic from 1968 to 2024. The primary objective was to examine the prognostic contribution of the International Consensus Classification (ICC), in the context of the Mayo Alliance Prognostic System (MAPS) for SM. World Health Organization classification (WHO‐HAEM5) subcategories included (i) indolent/smoldering SM (ISM/SSM; N = 518), (ii) SM associated with another hematological neoplasm (SM‐AHN; N = 273), with the latter including both myeloid and lymphoid neoplasms, (iii) aggressive SM (ASM; N = 106), and (iv) WHO‐defined mast cell leukemia (MCL; N = 13), which included mast cells with both “mature” and “immature” morphology. The ICC‐defined subcategories were mostly similar with the exception that SM‐AHN was replaced by SM associated with another myeloid neoplasm (SM‐AMN; N = 235) and WHO‐defined MCL was replaced by ICC‐defined MCL (N = 8), which included only those with immature MC morphology. Overall survival (OS) was similar between WHO‐defined MCL (median 1.8 years) vs. SM‐AHN (median 2.3 years; p = 0.3) but significantly different between ICC‐defined MCL (median 0.08 years) vs. SM‐AMN (median 2.0 years; p < 0.01). Significant difference in OS was also apparent between ICC‐defined SM‐AMN and SM associated with lymphoid neoplasm (SM‐ALN; median 8.1 years; HR 3.4; p < 0.01). Multivariable analysis confirmed the inter‐independent prognostic contributions of both ICC‐defined morphologic subcategories and MAPS risk variables, including age > 60 years, anemia, alkaline phosphatase > ULN, and platelet count < 150 × 109/L (p < 0.03 in all instances); the same was not true for WHO‐HAEM5‐defined SM subcategories. The addition of mutational information into the multivariable model resulted in ousting anemia and inclusion of ASXL1 (p < 0.01), SRSF2 (p = 0.01), and NRAS (p = 0.01) mutations as additional risk factors. Classification of SM by ICC is prognostically more accurate, compared to WHO‐HAEM5, and strengthens the prognostic contribution of morphology to current clinical and molecular risk models.
