Abstract Background Pregnancies complicated by gestational diabetes mellitus (GDM) are associated with increased risks of adverse perinatal outcomes, and with long-term metabolic and cardiovascular consequences for both mother and child. The original EMERGE randomized controlled trial (RCT) evaluated the effectiveness of early metformin in addition to usual care in women with GDM on glycaemic control and perinatal outcomes. The EMERGE Mothers and Kids study is a longitudinal follow-up of the EMERGE trial participants, designed to investigate the long-term metabolic, cardiovascular, and neurodevelopmental outcomes in mothers and their offspring. Methods This is a prospective, observational cohort study of participants and their children from the EMERGE trial (NCT06327191). A single follow-up visit will be conducted up to 6 years after the index pregnancy. Maternal assessments include anthropometric data, glucose tolerance, and metabolic parameters. Child assessments include growth metrics, adiposity measured via skinfold thickness, and neurodevelopmental status assessed through validated questionnaires. Additional data on quality of life, mental health, breastfeeding, and health economics will also be collected. Discussion This study aims to provide insights into the long-term safety and efficacy of metformin use during pregnancy and its potential impact on the long term maternal and child health outcomes, contributing to evidence-based management of GDM.

INTRODUCTION: Colorectal cancer remains a leading cause of cancer associated death in the United States and colonoscopy the primary screening strategy for prevention. Rates of adenomatous and serrated neoplasia detection are inversely associated with postcolonoscopy colorectal cancer. This crucial quality metric depends on accurate ascertainment of colorectal neoplasia findings from both endoscopy and histopathology records. We aimed to assess the feasibility of a random forest machine learning model to rapidly and accurately categorize colorectal neoplasia from electronic health record data. METHODS: A retrospective cohort study compared neoplasia detection rates among individuals undergoing colonoscopy at a large academic institution to develop a rule-based algorithm to categorize colorectal neoplasia from endoscopy reports and pathology systematized nomenclature of medicine – clinical terms. This cohort provided a large training set to develop a natural language processing system using a random forest approach to automatically classify unstructured pathology findings into adenoma, serrated, or advanced neoplasms. This system was manually validated through an independent holdout set. RESULTS: The training set comprised 35,953 unstructured pathology reports with matched systematized nomenclature of medicine – clinical terms from 95,188 unstructured colonoscopy reports. The final model was assessed on an independent holdout set of 337 manually annotated procedures obtaining an area under the receiver operating characteristic curve of 0.997 (confidence interval [CI] 0.994–1), 0.99 (CI 0.98–1), and 0.99 (CI 0.98–0.99) for prediction of adenoma, serrated, and advanced lesions, respectively. DISCUSSION: The random forest-based hybrid natural language processing system for classification of colonoscopy results was both accurate and explainable. NLP combined with effective machine learning algorithms can provide a scalable strategy for colonoscopy quality monitoring.

Abstract Introduction: Warm autoimmune hemolytic anemia (wAIHA) is a rare, life-threatening, relapsing, autoantibody-driven disease associated with a significant physical, emotional, and quality of life burden on patients and caregivers. In rare diseases like wAIHA, patients more often rely on publicly available online disease information to improve their health literacy, however available data and educational resources on the internet are often limited. Rapidly evolving technology has led to a rise in patients and care partners utilizing online digital health resources to gather information and seek support. Developing patient-facing educational materials in collaboration with the end user may help increase utilization and engagement, which would facilitate improving patient health. This qualitative patient research aimed to gather feedback from individuals living with wAIHA on creative concepts for a disease state education website and to gain insight on proposed content areas for the educational resource. Methods: A wAIHA patient council was convened to better understand the perspective of individuals living with wAIHA. US-based adults with a self-reported diagnosis of wAIHA who were members of the patient council participated in a 2-hour virtual focus group to discuss a wAIHA disease state education website concept and provide insight into potential gaps in patient education. Participants were permitted to provide feedback in an online questionnaire as an alternative to joining the session. The session focused on reviewing the website design concept and four proposed content areas. Focus group discussions were audio-recorded and transcribed. Transcripts were qualitatively analyzed to identify key themes and insights. Results: Four individuals living with wAIHA participated in the virtual focus group and one gave feedback via the online survey. Most participants were female (80%) and White (60%). Participants expressed an unmet need for a reliable and easy to understand educational website that could be utilized by patients, care partners, and their loved ones throughout the wAIHA journey. The most important information for the wAIHA educational website, as identified by participants, included disease state information (ranging from basic disease explanations/definitions to comprehensive data on the disease), resources for patient support groups, and patient testimonials. Proposed content areas included suspected wAIHA, understanding wAIHA, living with wAIHA, and resources and support; these were all deemed valuable by participants. They recommended enhancements like creating a dedicated section for family and care partners, offering guidance on parenting with wAIHA, and providing further explanations of disease-related terms and resources. Insights gathered on the initial website design concept provided actionable changes to content such as alternative imagery to emphasize the wAIHA community and refinement of text to reinforce the website as a guiding tool for patients and care partners. Participant feedback was incorporated into the final concept resulting in a patient-centered digital resource. Conclusions: Including perspectives of individuals living with wAIHA in the development of patient-facing educational resources is key to creating impactful tools for the intended user. Insights collected from this exploratory research directly contributed to the improvement of the concept for a wAIHA disease state education website, making it more engaging and impactful. This research demonstrates the value of focus groups in gaining insight into patient preferences for educational resources and guiding their development to be customized for the end user.

Background Immune‐checkpoint inhibitors (ICI) are associated with adverse cardiac events. Although troponin elevation is a diagnostic criterion for ICI‐related myocarditis (ICIrM) and myocardial infarction, data on other causes of troponin elevation and their outcomes in ICI‐treated patients are limited. Methods All patients treated with ICI who had hs‐TnT (high‐sensitivity troponin T) measured at a multicenter institution from 2011 to 2022 were included. Clinical data, outcomes (cardiac death, heart failure (HF), major adverse cardiovascular events [myocardial infarction, stroke, heart failure]), and cause of hs‐TnT elevation were assessed. Risks of cardiac events were compared across hs‐TnT elevation causes. Results Of 5423 patients treated with ICI, 1669 had post‐ICI hs‐TnT measurement (mean age 68.7±11.3 years, 58.3% male), with 1‐year follow‐up. Hs‐TnT elevation in patients with ICIrM (n=59) was associated with the highest risk for cardiac death (hazard ratio [HR], 52.7 [95% CI, 11.7–238.0], P <0.001), followed by hs‐TnT elevation due to heart failure (HR, 15.9), myocardial infarction/type 2 ischemia (HR, 11.6), and infection/sepsis (HR, 5.7), compared with those with no hs‐TnT elevation. ICIrM also carried highest risk for major adverse cardiovascular events (HR, 8.2, [95% CI, 4.4–15.3], P <0.001), followed by myocardial infarction/type 2 ischemia (HR, 8.1), heart failure (HR, 7.6), pulmonary embolus (HR, 5.1), infection/sepsis (HR, 4.1), and indeterminate cause (HR, 2.4). Among ICIrM, HsTnT value >576 ng/L best predicted risk for cardiac death and >319 ng/L for major adverse cardiovascular events. Conclusions Hs‐TnT elevation after ICI therapy is associated with increased risk of cardiac events, particularly in ICIrM, and a graded prognostic association depending on the cause of hs‐TnT elevation. Identifying the underlying cause and troponin thresholds may guide risk stratification and management.

Abstract This review explores smart catheters as an emerging class of medical devices that combine embedded sensors, robotics, and communication systems with increasing functionality and complexity to enable real‐time health monitoring, diagnostics, and treatment. Evolving from traditional catheters used as drains or entry ports, smart systems are now able to track blood pressure, temperature, biochemical signals, and mechanical forces within the body with a high degree of accuracy. Advances in materials, wireless communication, and robotic navigation have helped reduce common risks like infection and catheter blockage while also improving precision catheter placement for minimally invasive procedures. This review highlights recent developments across a variety of different types of smart catheters, ranging from sensing and imaging tools to therapeutic and multimodal systems. Additionally, it discusses the challenges that remain, including biocompatibility, long‐term performance, and clinical translation. The incorporation of new capabilities is changing how catheters are used, and these new uses promise to enable more personalized and responsive healthcare.

Background: Meniscal preservation has been demonstrated to contribute to long-term knee health and has been a successful intervention in isolation and in patients with anterior cruciate ligament reconstruction (ACLR). The long-term results of meniscal repair in the setting of revision ACLR have yet to be documented. Purpose: To report the incidence of meniscal repair failures at the 6-year follow-up in a cohort of patients who underwent concurrent revision ACLR and primary meniscal repair. Study Design: Prospective cohort study; Level of evidence, 2. Methods: All revision ACLRs with concomitant primary meniscal repair cases from a multicenter group between 2006 and 2011 were selected. Six-year follow-up was obtained to determine whether any subsequent surgery had occurred since their initial revision ACLR. If so, operative reports were obtained, whenever possible, to verify pathological condition and treatment. Results: In total, 221 patients from 1234 revision ACLRs underwent concurrent primary meniscal repairs (18% of the cohort). There were 238 repairs performed: 173 medial and 65 lateral. The majority of these repairs (n = 181; 76%) were performed with an all-inside technique. Six-year surgical follow-up was obtained in 77% (171/221) of the cohort, or 189 of 238 (79%) of the repairs (136 medial, 53 lateral). The meniscal repair failure rate, defined as reoperation, was 16% (31/189) at 6 years. Of the 31 failures, 28 were medial (24 all-inside, 4 inside-out; 28/136 = 20.6% failure rate) and 3 were lateral (2 all-inside, 1 inside-out; 3/53 = 5.7% failure rate). Three medial failures were treated in conjunction with a subsequent repeat revision ACLR. Medial tears underwent reoperation for failure at a significantly higher rate than lateral tears (20.6% vs 5.7%; P = .01) and had a significantly shorter survival time compared with lateral tears ( P = .02). No difference was found between the failure and nonfailure groups when it came to tear type, tear length, repair technique utilized, suture/implant type, or number of sutures used between the 2 groups. Conclusion: Meniscal repair in the revision ACLR setting has a 16% failure rate at 6 years. Failure rates for medial tears (20.6%) were found to be higher than that for lateral tears (5.7%), which aligns with previous studies in both the revision and primary ACLR setting.

Introduction: Complex congenital heart disease (CHD) patients with atrial arrhythmias have higher rates of morbidity and mortality compared to less complex CHD patients. This study aims to identify echocardiographic predictors of thromboembolism (TE) and major bleeding in patients with Tetralogy of Fallot (ToF) or Pulmonary Atresia with Intact Ventricular Septum (PA-IVS) and atrial fibrillation or flutter (AF). Methods: This cohort study included patients with ToF or PA-IVS who had a diagnosis of AF who underwent a TTE across three sites. Outcomes were incidence rate of major bleeding or TE, calculated using univariable and multivariable cox regression with interaction for anticoagulant choice and fractional area change (FAC). The HAS-BLED score was augmented with major predictors of bleeding, and receiver operator curves compared. Results: We included 300 patients (287 ToF [95.7%], 13 PA-IVS [4.3%]), mean age 45.6 years. Most received warfarin (227 [79.4%]), 40 (13%) used DOACs, and 5 (1.6%) used enoxaparin. TTE predictors of TE included large LVOT diameter ≥3cm (HR 8.92, p=0.002), small LVOT VTI (p=0.014), FAC <30% (HR 7.08, p=0.026) and moderate RV dysfunction (HR 10.75, p=0.026). Predictors of major bleeding included moderate tricuspid regurgitation (HR 2.40, p=0.022), right atrial pressure (1.12, p<0.001), severe RA enlargement (HR 2.30, p=0.048), RV mid diameter (HR 1.06, p=0.005), RV end diastolic area (HR 1.04, p=0.021), RV end systolic area (HR 1.05, p=0.016) elevated RVSP and FAC ≤45% (HR 0.37, p=0.016). Among warfarin users, impaired RV function (FAC ≤45%) was linked to reduced major bleeding events (HR 0.27, p=0.025). There was a nonsignificant trend towards higher bleeding in DOAC users with FAC >45% (HR 3.87, p=0.284), but significantly higher bleeding in DOAC users with FAC ≤45% (HR 12.41, p=0.008) vs. warfarin users with normal RV function (table 1). We developed an augmented HAS-BLED score: the standard score plus one point for moderate-to-severe pulmonic or tricuspid regurgitation and one for FAC ≤45%. This outperformed the standard HAS-BLED in predicting major bleeding (AUC 0.67 augmented vs. 0.57 un-augmented, p=0.008) (figure 1). Conclusion: Echocardiographic evidence of right heart disease is a strong predictor of major bleeding in patients with ToF or PA-IVS. FAC is a useful tool to determine excess major bleeding risk, particularly in DOAC users. Augmenting HAS-BLED with right heart parameters improves diagnostic accuracy.

ABSTRACT Introduction and Objectives Female urethral strictures remain a challenging clinical entity with limited data on optimal reconstructive techniques. This study presents 12‐month clinical and patient‐reported outcomes following a novel transurethral approach to dorsal inlay buccal graft urethroplasty. Methods We evaluate the outcomes of consecutive female patients with urethral strictures treated via dorsal inlay buccal graft urethroplasty from October 2021 to November 2024. Preoperative evaluation included cystoscopy, uroflowmetry, and/or voiding cystourethrogram. Follow‐up at 4 and 12 months included cystoscopy, uroflowmetry, and patient‐reported outcomes measured via the Global Response Assessment. Success was defined as absence of recurrence on cystourethroscopy. Results Twenty‐one patients were included in the study, with 95% having undergone prior treatments (90% dilation/DVIU and 9% urethroplasty). Stricture locations varied across the distal (33%), mid (19%), proximal (19%), and multifocal/pan urethral (19%). The median operative duration was 60 min (IQR: 56–86) and all were discharged on the day of surgery. Nineteen patients (90%) underwent a dorsal inlay procedure, while two (10%) required combined dorsal and ventral inlay due to obliterative stricture. No complications were observed. The median follow‐up was 13.2 (IQR: 5.1–23.5) months, during which time 1 patient underwent retreatment for recurrent stricture. Clinical success was 95% at 4 months and 92% at 12 months. Median peak urinary flow rate preoperatively versus 4‐month postoperatively was 7.0 cc/s versus 13.0 cc/s ( p = 0.20) and at 12‐month postoperatively was 13.3 cc/s ( p = 0.50). 90% of patients reported improvement on the Global Response Assessment. There were no cases of de novo stress urinary incontinence. Conclusions This novel transurethral dorsal inlay buccal graft urethroplasty offers a safe and efficient treatment for female urethral strictures with durable clinical and patient‐reported outcomes at 12 months. The technique's minimal urethral mobilization translates into shorter operative times and a low risk of stress incontinence, making it a promising alternative to traditional approaches.

Summary Recipients of haploidentical and unrelated haematopoietic cell transplants (HCTs) historically had a higher risk for graft‐versus‐host disease (GvHD). However, with improved GvHD prophylaxis, recent data suggest adult patients undergoing transplantation from unrelated or mismatched donors now experience the rates of GvHD similar to those receiving matched related donor grafts. This finding is not yet explored in paediatric patients. The objectives of this study were to: (1) compare acute and chronic GvHD incidence, mortality and GvHD‐free relapse‐free survival (GRFS) among matched related donor (MRD), matched unrelated donor (MUD) and haploidentical paediatric HCT recipients in the era of enhanced GvHD prophylaxis for high‐risk patients, (2) identify independent risk factors for GvHD and (3) evaluate the efficacy of various GvHD prophylactic regimens in our cohort. We conducted a retrospective, single‐centre medical record abstraction among patients aged 0–25 years who underwent allogeneic HCT for any indication. The results demonstrated that 5‐year cumulative incidence rates of any GvHD, all‐cause mortality and GRFS are similar across the haploidentical, MRD and MUD groups. Tacrolimus‐containing doublet/triplet regimens were associated with decreased GvHD, as compared to ciclosporin. Adding alemtuzumab also decreased risk for GvHD, without increasing relapse rates. Prospective studies with larger cohorts are warranted to further optimize outcomes for paediatric allogeneic HCT patients.

OBJECTIVES The 2-bag intravenous (IV) fluid system for diabetic ketoacidosis (DKA) has been associated with shorter duration of insulin and faster resolution of acidosis. Our aims were to increase the use of 2-bag IV fluids among children with medium- or high-risk DKA treated at 2 tertiary care pediatric hospitals and to increase the proportion of children who receive timely administration of fluid and insulin treatments. METHODS We conducted a quality improvement initiative using data from January 1, 2014, to December 31, 2021, among patients 21 years or younger with medium- or high-risk DKA. The study spanned pre- and post-initiative periods and a stability period. Our interventions included development of a clinical practice guideline, education, and electronic medical record updates. Statistical process control methods were used to evaluate outcome changes. RESULTS We identified 876 eligible encounters. Age, sex, and the proportion of children with medium- or high-risk DKA were similar across study periods. A higher proportion of non-Hispanic Black children was observed in the stability period (26.3%) than the pre- (17.7%) and post-initiative (18.2%) periods. We observed an increase in 2-bag IV fluid use from an average of 41.3% to 77.7%. We did not observe changes in time to isotonic fluid bolus, continuous insulin, or 2-bag IV fluids. There was no change in hypoglycemic events. CONCLUSION We increased the proportion of children with medium- or high-risk DKA treated with 2-bag IV fluids through a combination of interventions, including implementation and refinement of a clinical guideline, creation of a nurse algorithm, and nursing education.
