Hematopoietic stem cells (HSCs) are defined by their capacity to regenerate all main components of peripheral blood, but individual HSCs exhibit a range of preferences for generating downstream cell types. Their propensities are thought to be epigenetically encoded, but few differential regulatory mechanisms have been identified. In this work, we explored the role of DNA methyltransferase 3A (DNMT3A) in the megakaryocyte-biased HSC population, which is thought to reside at the top of the hematopoietic hierarchy. We demonstrate that heterozygous loss of DNMT3A (Dnmt3a+/-) in these megakaryocyte-biased HSCs has distinct consequences compared with the rest of the HSC pool. These megakaryocyte-biased …

8-oxoguanine (8-oxoGua) is one of the most frequent forms of oxidative DNA base lesions, repaired by 8-oxoguanine DNA glycosylase 1 (OGG1) via base excision repair (BER) pathway to maintain genome fidelity. The human allelic variant hOGG1^S326C, prevalent in Caucasians and Asians, has been regarded as a susceptibility factor for various diseases, yet its pathogenic mechanism remains elusive. In this study, we demonstrate that Ogg1^S326C/S326C mice exhibit increased and sustained airway inflammation compared with wild-type (WT) Ogg1^S326/S326 mice. Mechanistically, in response to inflammatory stimulation, OGG1S326C undergoes reactive oxygen species-induced dimerization, which impairs its base excision function, but …

Negative pressure wound therapy (NPWT) is widely recognized for its efficacy in treating diabetic wounds, but the mechanisms involved in the wound healing process remain unclear. By examining changes in blood cytokine levels as molecular signaling precursors, we aim to provide a comprehensive cytokine profile to support adjunctive therapy research and clinical applications. A diabetic mouse wound model was established to compare cytokine profiles between NPWT-treated and standard dressing groups, identifying key signaling candidates that may facilitate wound healing. By integrating normal mouse data with large-scale cytokine analysis, we developed a time-stratified NPWT approach to track acute-phase cytokine fluctuations in …

Advances in Cancer Education and Quality Improvement

Background

Surgeons provide up to 10% of total opioid prescriptions across all specialties, and more than one-third of surgeon-prescribed medications are opioids. Patient-reported opioid consumption and risk of persistent opioid use beyond the postoperative recovery period correlate with the initial opioid quantity prescribed at discharge. Interventions to reduce postoperative opioid prescribing have demonstrated no adverse effects on pain control or increased need for prescription refill; however, in the absence of standardized prescription protocols, opioid prescribing practices vary widely.

Objective

The study objective is to identify the opioid prescribing model that provides the lowest oral morphine equivalents (OME) volume prescribed at …

Reducing Antibiotic Duration For Pneumonia And Sinusitis In The Emergency Department: A Quality Improvement Approach, Joshua Saucedo, Leslie Hueschen, Amanda Nedved, Marsha Dannenburg, Patricia Phillips, Jennifer Floyd, Alaina N. Burns, Rana El Feghaly

Research Days

Background: Our aim is to increase the percentage of children discharged home from the ED with a diagnosis of CAP or ABRS treated with an optimal antibiotic duration (3-5 days for CAP, 5-7 days for ABRS) from 13% to 70% by July 25.

Methods: Outcome metric is the percentage of patients receiving recommended antibiotic duration for CAP and ABRS. Process metrics include use of order set, "Quick Discharge” order set, and clinical pathway QR codes. Balancing metric is the number of return visits with the same diagnosis < 14 days. Plan-Do-Study-Act methodology was used. In Aug 23, our ASP disseminated a handbook that emphasized shorter durations. A new multidisciplinary team (infectious diseases, ED, and urgent care physicians, advanced practice providers, nurses, and pharmacy) formed in Dec 23. We utilized cause-and-effect analysis, driver diagram, and prioritization matrix, which helped identify other impactful interventions, including implementation of new internal CAP clinical pathway order set (April 24) and “Quick Discharge” order sets (May 24). Next, we surveyed prescriber comfort (June 24) with shorter duration identifying barriers and providing education, leading to posted evidence for lower duration treatment in practitioner workrooms and developing a new ABRS clinical pathway (Sept 24). Top prescribers providing optimal duration received email acknowledgement (Oct 24) and resident rotators received antibiotic handbook and CAP clinical pathway QR codes (Nov 24). New best treatment practices for ABRS were elucidated and disseminated through clinical pathway and internal article publishing to our hospital and associated clinics (Dec 24).

Results: We saw shifts in the outcome metric’s center line in Sept 23 …

A Case Of Heterotaxy And Common Atrioventricular Canal With Bradycardia, Mohamed Aashiq Abdul Ghayum, Jenna Schermerhorn, Hayley S. Hancock, Kelsey Brattrud, Melanie Kathol, Maria Kiaffas

Research Days

Background

Heterotaxy-polysplenia syndrome (otherwise known as left atrial isomerism) should be suspected in the presence of complete atrioventricular canal defect (CAVC) with interruption of the inferior vena cava (IVC), atrioventricular block (AVB), and viscero-cardiac heterotaxy. The prognosis remains dismal for the fetus with such entity, especially in the presence of major structural heart disease and high-grade atrioventricular block. Early diagnosis, close follow up, and appropriate delivery planning, allows for effective stabilization of the baby after birth and might improve survival.

Methods

A 26-year-old mother at 26 weeks gestational age was referred for cardiac evaluation of cardiomegaly, suspected CAVC and bradycardia. …

Utilization Of Physical Activity As A Vital Sign (Pavs) To Improve Personalized Exercise Assessment And Counseling In Pediatric Cardiology Patients, Lavina Desai, Josh Holbert, Jessica S. Watson, Amanda Mcintosh, David A. White, Megan Jensen

Research Days

Background: Physical activity is a known preventative effort that has a clear role in improving cardiorespiratory fitness and health outcomes. Low levels of habitual physical activity (PA) in children and adolescents with congenital heart disease (CHD) leads to various negative health outcomes, yet review of the literature indicates that physicians, caregivers, and patients restrict physical activity owing to safety concerns [1]. Root cause analysis (Fig 1.1) identified a lack of readily available data to provide assessment of baseline PA in patients presenting to the cardiology clinic. Therefore, this project aims to implement physical activity as vital sign (PAVS) via a …

Optimal Diagnostic Strategies For Concussion-Related Vision Disorders: A Review, Iniya K. Adhan, Kammi B. Gunton

Wills Eye Hospital Papers

Concussions are a mild form of traumatic brain injury (TBI) that is typically self-limited and transient with a high prevalence within our communities. Due to the vast visual network interconnectivity, visual symptoms secondary to a concussion occur about 90% of the time. A gold standard to confirm concussion acutely has not been well established. Visual function testing based on symptoms remains the standard of care in off-site evaluation for diagnosis of oculomotor dysfunction. This review covers the current diagnostic strategies for vision based disorders post-concussion for sideline testing, off-site testing, and research driven testing.
