OBJECTIVE:Pediatric tracheostomy emergencies are high-acuity events requiring rapid, coordinated team-based care. This study assessed objective team performance and used in situ simulation to identify systems factors, including latent safety threats (LSTs) and resilience supports, that influence pediatric tracheostomy emergency readiness across diverse clinical settings. METHODS:In situ simulations of pediatric tracheostomy emergencies (obstructed or partially dislodged tubes) were conducted across inpatient floors, critical care units, and emergency departments at 11 pediatric hospitals. Time to completion of critical actions was recorded using the NeoCHART+™ for PEAK-II mobile application. Structured debriefs identified LSTs and resilience supports at unit and hospital levels. Multivariable Cox proportional hazards models assessed predictors of time-critical actions (tube replacement, suction, first effective ventilation) and the percentage of critical actions completed. RESULTS:Sixty-seven baseline simulations were conducted across 11 institutions. Seventy-seven percent of teams replaced an identical tracheostomy tube within 5 minutes (median 188.4 seconds, [IQR 165.3, 204.6]). Teams reported a median of 3.2 LSTs per simulation (IQR 3.0, 4.0). Common LSTs included attempted ventilation through occluded tracheostomy tubes, unclear leadership, ambiguous role definitions, and non-standardized equipment locations. Teams with a RT and at institutions with a dedicated tracheostomy team performed time-critical actions faster. DISCUSSION/CONCLUSIONS:In situ simulation revealed LSTs, resilience supports, and performance variability that may influence effective pediatric tracheostomy emergency response at the systems level. IMPLICATIONS FOR PRACTICE/CONCLUSIONS:Variability identified in systems factors and team performance can guide targeted interventions to improve pediatric tracheostomy emergency preparedness.

BACKGROUND:Endoscopic sleeve gastroplasty (ESG) is increasingly utilized for treating obesity, but some patients may subsequently present for conversion to a surgical procedure. Foreign material or distorted anatomy may make conversion more challenging. The preoperative evaluation, intraoperative findings, and postoperative outcomes of converting ESG to bariatric surgery are not well described. METHODS:Bariatric surgery patients at a single center with history of ESG were identified by review of electronic medical records from 2016 to 2026. Background characteristics, preoperative imaging, endoscopic findings, intraoperative details, and outcomes were obtained by chart review. Intraoperative videos were obtained when possible. RESULTS:. Most patients (19/20, 95%) underwent preoperative esophagram, which showed a tubularized stomach in half of cases (10/19, 53%) but no radiopaque materials precluding conversion to surgery. Preoperative endoscopy (n = 5) and intraoperative endoscopy (n = 3), when performed, revealed no apparent gastroplasty. Intraoperative findings included mild adhesions around the stomach, with sutures sometimes visible, but an otherwise native stomach not requiring any changes to the staple line. Mean total weight loss was 29.1% at 1 year postoperatively. No stapler misfires occurred, and none of the postoperative complications were related to the gastric staple line. There were no gastric staple line leaks or bleeds. CONCLUSION/CONCLUSIONS:In our experience, sleeve gastrectomy and gastric bypass were both technically feasible and relatively straightforward to perform in patients with a history of ESG.

Clonal hematopoiesis of indeterminate potential (CHIP) and clonal cytopenia of undetermined significance (CCUS) are increasingly recognized as risk factors for hematologic malignancy, cardiovascular disease, and inflammatory disorders. While dedicated clonal hematopoiesis (CH) clinics have emerged to address these risks, referral patterns have not been systematically described. We conducted a retrospective chart review of 126 consecutive adults referred to a CH clinic within a large academic health system from 2021 and 2023. Referral sources, diagnostic reasoning, and outcomes were examined, incorporating molecular, cytogenomic, and bone marrow findings. Primary care providers accounted for the largest proportion of referrals (31.7%), followed by Hematologists (23.8%) and Genetic Counselors (17.5%). Fifteen patients were diagnosed with CHIP and fifteen with CCUS. Among referrals for cytopenias, two-thirds carried pathogenic variants detected by targeted sequencing, often leading to diagnostic reclassification. Case vignettes illustrate referrals from oncology, gastroenterology, and primary care, demonstrating diverse settings in which CHIP and CCUS are encountered. To our knowledge, this is the first systematic analysis of referral patterns to a CH clinic within a multispecialty network. These findings underscore the importance of multidisciplinary engagement in early detection, supports integrating molecular testing in hematologic evaluation, and provides a framework for standardized referral strategies and future clinical trial enrollment.

BACKGROUND:Sickle cell disease (SCD) stands as one of the most prevalent genetic disorders in the United States (U.S.) that causes severe consequences such as organ damage and excruciating pain. Alarmingly, recent literature indicates a decline in the number of people living with SCD (PLWSCD) seeking professional care - hinting at an avoidance of the healthcare system. Therefore, this scoping review synthesizes the evidence regarding barriers and facilitators influencing healthcare utilization among PLWSCD within the U.S. METHODS:To map the current literature on SCD management and provide a comprehensive overview of the current knowledge gaps regarding healthcare utilization for PLWSCD, a scoping review was conducted. A systematic search of articles reporting on the utilization of healthcare among PLWSCD in the U.S using seven data sources was conducted on March 24, 2023, without any restrictions on publication date and language. To capture any additional articles, the search was updated on March 4, 2024. Two reviewers independently assessed studies for inclusion, data extraction, and risk of bias (RoB). MAIN RESULTS/RESULTS:A total of 708 articles were screened; 70 met the study criteria. Results indicated that the four most common barriers were social (n = 25) interpersonal (n = 23), economic (n = 15), and institutional level factors (n = 11). The top four most common facilitators were technology (n = 9), education (n = 7), autonomy (n = 6), and a positive patient-provider relationship (n = 6). The most common forms of healthcare utilization were inpatient or hospital admissions (n = 19) and emergency department (ED) visits (n = 18). Evidence-based interventions (EBI) found to decrease healthcare avoidance included individualized pain plans (IPPs) (n = 4) and quality improvement (QI) strategies (n = 3). CONCLUSION/CONCLUSIONS:This scoping review identified complex multilevel barriers that impede healthcare utilization, and facilitators likely to promote healthcare utilization among PLWSCD in the U.S. Future research should prioritize developing and evaluating comprehensive, multi-level interventions that address identified barriers while leveraging facilitators to improve healthcare engagement and outcomes for this vulnerable population. Healthcare systems and health policies must urgently adopt and integrate evidence-based strategies to rebuild trust and ensure equitable, accessible care for PLWSCD.

BACKGROUND/UNASSIGNED:Nontuberculous mycobacteria pulmonary disease (NTM PD) has been increasing in the United States, and New York City is an important hotspot, with a high burden of disease. RESEARCH QUESTION/UNASSIGNED:We assessed how neighborhood-level risk factors influenced NTM PD prevalence in New York City. STUDY DESIGN AND METHODS/UNASSIGNED:We used outpatient claims data from hospitals participating in the Patient-Centered Outcomes Research Institute network, compiled by the INSIGHT Clinical Research Network at Weill Cornell Medicine. NTM PD period prevalence (referred to here as 'prevalence') was estimated by New York City neighborhood for the study period 2012 through 2022. A case was defined as someone with at least one claim for NTM PD. De-identified NTM PD case data and demographic data were analyzed by neighborhood of residence at diagnosis. Using prevalence estimates, we detected high- and low-prevalence regions within New York City and associated these estimates with demographic, clinical, socioeconomic, and environmental neighborhood-level factors using Poisson regression and backward elimination of covariates. RESULTS/UNASSIGNED:Overall, 6,169 NTM PD cases were identified among persons receiving care across 17 private New York City hospitals. The mean age was 67.5 years, 68.7% were female, and 57.3% were White. Over the study period, NTM PD prevalence increased throughout New York City, and median year built of housing units, median income, and median age of residents were significant neighborhood-level risk factors. The highest prevalence neighborhoods were in Manhattan, while the lowest prevalence neighborhoods were in Brooklyn and Staten Island. INTERPRETATION/UNASSIGNED:Our findings indicate that neighborhood-level access to care may explain the heterogeneity in NTM PD prevalence among New York City neighborhoods, as higher income, newer neighborhoods exhibited the highest NTM PD prevalences. Future studies should examine the extent of undetected NTM PD in New York City, particularly in low-income areas.

BACKGROUND:While there is evidence of the benefits of healthy maternal lifestyle behaviors (eg, physical activity plus a healthy diet) on cardiometabolic health, there are limited data on the independent association between physical activity and cardiometabolic health among women with a history of gestational diabetes mellitus (GDM). OBJECTIVE:In this study, our aim was to explore the association between device-assessed physical activity and cardiometabolic outcomes in Chinese American women, a group disproportionately affected by GDM and type 2 diabetes. METHODS:A cross-sectional study was conducted among 33 Chinese American women (0.5-5 years after delivery) with a history of GDM in New York City in 2023 to 2024, in which we collected their device-assessed physical activity data, online survey data (in Mandarin and English), and cardiometabolic data (via fasting blood samples). Descriptive, unadjusted, and adjusted regression analyses were performed. RESULTS:Participants' mean age was 38.2 ± 3.3 years (2.6 ± 1.5 years after delivery), and body mass index was 23.5 (interquartile range: 21.7-25.1) kg/m 2 . Among the 33 participants, 27.3% had prediabetes, 51.5% had lipid dysregulation, and 21.2% had elevated blood pressure. The duration of moderate-to-vigorous physical activity per week was 132.4 (interquartile range: 90.5-272.0) minutes, and 46.9% of the cohort met the physical activity recommendation of ≥150 minutes moderate-to-vigorous physical activity per week. In regression models, meeting the physical activity recommendations was inversely associated with total cholesterol (-27.6 ± 12.7 mg/dL) and low-density lipoprotein cholesterol (-25.5 ± 10.6 mg/dL) levels (both P <.04). CONCLUSIONS:The majority of participants engaged in suboptimal physical activity levels. However, meeting physical activity recommendations was associated with better total and low-density lipoprotein cholesterol levels. Targeting physical activity may be a key strategy for improving cardiometabolic health in Chinese American women recently diagnosed with GDM.

IMPORTANCE/UNASSIGNED:Transvaginal pelvic imaging is an integral and sensitive aspect of gynecologic care that individuals find both invasive and burdensome. At-home transvaginal imaging provides an opportunity to navigate these barriers to care. OBJECTIVE/UNASSIGNED:To evaluate the use of at-home transvaginal ultrasonography for gynecologic assessment, as measured by diagnostic imaging quality and participant satisfaction, in a broad sampling of women aged 22 to 50 years. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:Prospective, interventional, single group nonrandomized clinical trial with blinded review of collected images from premenopausal women aged 22 to 50 from Florida, Massachusetts, Maryland, Maine, Minnesota, New Hampshire, Texas, Utah, Virginia, Vermont, and Washington, DC. Images were gathered between July 2022 and July 2023, and data were analyzed from April to September 2025. INTERVENTION/UNASSIGNED:At-home pelvic ultrasonography guided by verbal communication with a fully trained remote sonographer who had real-time access to study images. Cine clips were used to capture standard views of the uterus, ovaries, cervix, and posterior cul-de-sac. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Primary outcomes were image quality and participant net promoter score (NPS), reflecting participants' likelihood of recommending the procedure, with higher scores indicating greater likelihood. Secondary outcomes included minor pain or discomfort, sonographer reported experience and/or pain, and all other adverse events. RESULTS/UNASSIGNED:A total of 265 participants (mean [SD] age, 32 [6.7] years; mean [SD] body mass index, 27.0 [5.6]) enrolled in the trial, and 263 ultrasonographic scans were completed. Image quality showed that 253 at-home ultrasonographic scans (96.2%) met diagnostic quality while 10 (3.8%) did not. NPS was significantly higher with use of the at-home ultrasonography (59) compared with in-clinic scans (24), with an adjusted difference of 33.7 (95% CI, 23.3-44.0; z = 6.35; P < .001). No adverse events were reported. CONCLUSIONS AND RELEVANCE/UNASSIGNED:This nonrandomized clinical trial of at-home pelvic ultrasonography in premenopausal women demonstrated that broad use of at-home gynecologic ultrasonography technology is feasible, safe, and preferred by participants and sonographers compared with in-clinic ultrasonography. At-home ultrasonographic imaging presented an innovative and clinically acceptable alternative to in-clinic care, providing opportunities for improved access to and decreased burden of gynecologic and reproductive care.

Acute kidney injury (AKI) and chronic kidney disease (CKD) are common conditions among patients with cirrhosis whose development is associated with increased morbidity and mortality. Recurrent episodes of AKI within this population can ultimately lead to CKD, while patients with underlying CKD are in turn more likely to experience AKI. Determining the etiology of kidney dysfunction in the setting of cirrhosis is often challenging given the considerable limitations of currently available diagnostic tools. Ongoing research into the role of novel serum and urine biomarkers may allow for more timely diagnosis and treatment of kidney injury among patients with cirrhosis. This review provides an overview of kidney dysfunction in cirrhosis with a focus on the role of these emerging biomarkers for diagnosis of AKI and CKD.

BACKGROUND:Final infarct volume (FIV) on 24-hour magnetic resonance imaging is a well-established imaging biomarker linked to functional recovery after ischemic stroke, yet its prognostic value in intracranial atherosclerosis-related large vessel occlusion remains poorly explored. The impact of adjunct intracranial stenting on both infarct size and progression also remains unclear in this population. This study aimed to examine the association between FIV and clinical outcome, evaluate the effect of adjunct stenting on FIV and infarct progression, and assess the relationship between infarct progression and functional independence. METHODS:We conducted a post hoc secondary analysis of the RESCUE-ICAS registry (Registry of Emergent Large Vessel Occlusion due to Intracranial Stenosis); only patients with anterior circulation large vessel occlusion with magnetic resonance imaging after thrombectomy were included. FIV was measured on diffusion-weighted magnetic resonance imaging performed 24 to 36 hours postthrombectomy. Infarct progression was defined as the difference between baseline computed tomography perfusion infarct volume (cerebral blood flow <30%) on presentation and 24- to 36-hour FIV. The primary outcome was 90-day functional independence (modified Rankin Scale score 0-2). Additional analyses evaluated the association between adjunct intracranial stenting and FIV, and the association between infarct progression and 90-day functional outcome. Associations were analyzed using multivariable logistic regression and inverse probability of treatment weighting. RESULTS:=0.008). CONCLUSIONS:Among intracranial atherosclerosis-related large vessel occlusion patients, 24- to 36-hour FIV is a strong predictor of functional outcome. Adjunct stenting is associated with smaller FIV. Lower infarct progression was also associated with favorable outcome. These findings highlight FIV as a reliable imaging biomarker and potential surrogate end point in future trials.
