KMT2A-rearranged (KMT2A-r) acute leukemias are especially prevalent in the pediatric population. KMT2A-fusion proteins drive leukemogenic gene expression through an interaction with a chromatin complex that includes the scaffold protein menin, giving rise to aggressive acute leukemias. RAS pathway mutations are also common in pediatric leukemia. In a cohort of 1750 patients enrolled on Children's Oncology Group (COG) trials, we identified RAS pathway mutations in 43% of acute myeloid leukemia (AML) cases. The presence of RAS pathway mutations in KMT2A-r AML was associated with a lower complete remission rate, poor event-free survival and overall survival (OS), and early relapses. Given the …

Biotic Therapies For Irritable Bowel Syndrome: Current Interventions, Gina Wodarczyk, Maria Winte, Diana Mastellone, Termen Singh, Joshua Desipio, Sangita Phadtare

Division of Gastroenterology and Hepatology Faculty Papers

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized by recurrent abdominal pain and changes in bowel habits without measurable disease processes. Recent research emphasizes the gut-brain-microbiome (GBM) axis and explores how microbiota influence gastrointestinal and central nervous system functions. Here, we first discuss a brief overview of various treatment approaches for IBS, focusing on interventions such as probiotics, prebiotics, or synbiotics that target the GBM axis in adults with IBS. Relevant trials discussed the use of probiotics, prebiotics, or synbiotics.

Slc Transporter-Mediated Functional Imaging In Cancer Diagnosis, Lumeng Zhang, Jun He

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Functional imaging has become an important approach for evaluating tumor physiology in vivo beyond morphologic assessment. Radiotracers used for cancer imaging are designed to mimic endogenous substrates or substrate analogues, and their accumulation can depend on membrane transport, intracellular metabolism, and clearance from normal tissues. Specifically, SLC transporters contribute to tracer uptake and signal formation, linking transporter activity with measurable imaging signals in cancer. While [18F]FDG PET/CT remains the most widely used example of transporter-associated metabolic imaging, SLC transporter-mediated imaging strategies have been developed to assess amino acid transport, sodium-dependent glucose uptake, redox metabolism, lactate exchange, nucleoside metabolism, choline metabolism, …

Depression And Anxiety In Pulmonary Hypertension Associated With Congenital Heart Disease: Pathophysiology And Clinical Implications Of The Heart–Brain Axis, Nicodemus N. Triatmojo, Valerinna Y.S. Putri

Journal of the Saudi Heart Association

Pulmonary hypertension associated with congenital heart disease or PH-CHD is an increasingly prevalent disorder in modern cardiology. It is characterized by progressive pulmonary vascular remodeling, chronic right ventricular (RV) pressure overload, and abnormal cardiopulmonary hemodynamic. Due to advances in congenital cardiology and treatments for pulmonary hypertension, survival rates have increased. As a result, the focus has switched to long-term functional status and quality of life. Depression and anxiety are currently recognized as prevalent and clinically significant manifestations in PH-CHD; nonetheless, they remain underdiagnosed and undertreated within cardiovascular care frameworks.

More study shows the disease's severity or symptom count cannot explain …

Exploratory metagenomic analysis revealed enrichment of Parasutterella excrementihominis …

Progesterone And Cerclage Together For Short Cervix: Evaluating Potential Complementary Effects For Improved Preterm Birth Prevention, Vincenzo Berghella, Ilaria Paladino, Moti Gulersen, Lauren Sayres, Amanda Roman, Rupsa C. Boelig

Department of Obstetrics and Gynecology Faculty Papers

Management of patients with a short cervical length (CL) on transvaginal ultrasound (TVU) often involves therapy with vaginal progesterone and/or cervical cerclage. Although these interventions are frequently viewed as alternative strategies, they may also represent complementary approaches targeting different mechanisms involved in spontaneous preterm birth. As in other areas of medicine, therapies with different mechanisms are often used together rather than as mutually exclusive options. In line with current level 1 evidence from randomized controlled trials (RCTs) and meta-analyses of RCTs on either vaginal progesterone or cerclage, in singleton gestations with no prior spontaneous preterm birth (SPTB), vaginal progesterone is …

Department of Neurosurgery Faculty Papers

BACKGROUND AND PURPOSE: Chronic subdural hematoma (cSDH) affects approximately 20 per 100,000 individuals annually, with surgical recurrence rates of 10-20%. Middle meningeal artery embolization (MMAE) has emerged as a promising minimally invasive treatment, but the optimal timing remains unclear. We evaluated the association between MMAE timing and radiological and functional outcomes in cSDH.

METHODS: We conducted a retrospective multicenter international cohort study across 33 centres, including patients who underwent MMAE for cSDH between January 2018 and December 2024. Patients were stratified by timing from diagnosis: Q1 (≤1 day), Q2 (2 days), Q3 (3-6 days), and Q4 (>6 days). The …

Preoperative Considerations For Cervical Cerclage (Part 1), Ilaria Paladino, Moti Gulersen, Amanda Roman, Rupsa C. Boelig, Vincenzo Berghella

Department of Obstetrics and Gynecology Faculty Papers

Transvaginal cervical cerclage remains a central strategy for preventing spontaneous preterm birth in appropriately selected pregnancies. Although decades of research have clarified which patients benefit most from cerclage, substantial heterogeneity persists in pre-, intra-, and postoperative management. This article, the first in a series on cerclage technique, synthesizes the evidence guiding preoperative decision-making. Cerclage is classified by indication as history-indicated cerclage, ultrasound-indicated cerclage and physical examination-indicated cerclage. History-indicated cerclage is recommended for patients with ≥3 prior early spontaneous preterm births or second-trimester losses < 28 weeks, prior ultrasound-indicated cerclage with delivery at< 32 weeks, or prior physical examination-indicated cerclage; twin gestation alone is not considered an indication. Ultrasound-indicated cerclage should be considered in singletons without prior spontaneous preterm birth with transvaginal ultrasound cervical length ≤20 mm and is recommended in singletons with prior spontaneous preterm birth when cervical length is ≤25 mm before 24 weeks' gestation; in twins, it may be considered when cervical length ≤15 mm before 24 weeks' gestation. Physical examination-indicated cerclage is recommended in singleton or twin gestations with asymptomatic cervical dilation ≥1 cm before 24 weeks' gestation. Timing varies by indication: history-indicated cerclage is typically placed at 12 to 14 weeks' gestation and is not urgent, whereas ultrasound-indicated cerclage and physical examination-indicated cerclage are usually performed between 16 and 23 6/7 weeks' gestation in response to cervical changes, ideally within 72 hours and 24 hours of diagnosis of short transvaginal ultrasound cervical length or dilated cervix, respectively. Preoperative evaluation should include a detailed anatomic ultrasound examination and appropriate genetic screening. Routine urogenital cultures are not indicated in the absence of symptoms. Amniocentesis is not recommended for history-indicated cerclage or ultrasound-indicated cerclage but should be considered before physical examination-indicated cerclage to evaluate for intra-amniotic infection. Adjunctive management remains variable. Progesterone is recommended for a short cervical lenght < =25mm before 24 weeks. Outpatient cerclage appears safe, with no clear benefit to routine inpatient management. Perioperative indomethacin and antibiotics are likely unnecessary for history-indicated cerclage but may be considered in ultrasound-indicated cerclage and are suggested for physical examination-indicated cerclage.

Student Papers, Posters & Projects

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a debilitating syndrome typically characterized by orthostatic headache and classic brain MRI findings. However, brain MRI abnormalities are indirect manifestations of cerebrospinal fluid (CSF) volume depletion rather than direct evidence of the leak, and some patients may present with unrevealing or absent typical brain MRI findings, posing a considerable diagnostic challenge.

METHODS: A comprehensive search of PubMed/Medline, Web of Science, and Scopus was conducted to perform a systematic review, according to PRISMA guidelines, analyzing the available evidence on MRI-negative SIH (patients without typical SIH findings on their initial brain MRI), including its clinical features, …

Student Papers, Posters & Projects

BACKGROUND AND AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) reduces mortality in esophageal variceal hemorrhage. Whether the COVID-19 pandemic worsened existing disparities in outcomes among patients undergoing TIPS remains unclear. We aimed to characterize racial, payer-based, and income-based disparities in post-TIPS outcomes before and after the COVID-19 pandemic.

METHODS: Using the 2016-2022 National Inpatient Sample, we conducted a retrospective cohort analysis of 31,860 weighted hospitalizations of adults with cirrhosis and esophageal variceal hemorrhage who underwent TIPS. Admissions were stratified as pre-COVID (2016-2019) and post-COVID (2020-2022). Primary outcomes were in-hospital mortality, length of stay, and total hospital charges. Multivariable regression models with …

Dosimetric Impact Of Replacing An Anterior Field With A 3d Conformal Anterior Partial Arc In Thoracic Spine Palliative Radiotherapy, Camri Garretson

Masters Projects

Purpose: Palliative radiotherapy is commonly used for the treatment of thoracic spine metastases; however, conventional beam arrangements can expose nearby organs at risk (OAR), including the heart, to unnecessary radiation dose. This study evaluated whether replacing a static anterior beam with a conformal anterior arc could reduce cardiac dose while maintaining adequate target coverage.

Methods: Fifteen thoracic spine treatment plans were retrospectively replanned using an experimental technique in which the static anterior beam from the original plans was replaced with a 3D anterior conformal arc. All other planning parameters, including beam geometry, wedges, and multi-leaf collimator margins (MLC), were kept …

Serial Drilling Technique For Sequential Subtrochanteric Femur Fracture Fixation In Pediatric Osteopetrosis: A Technical Report., Adam Mansour, Josiah J Wolf, Ivan Slyepkan, Morgan Turnow, Michael Anderson, Anthony Wing, Jack Iandoli, Craig Goubeaux, Craig Smith, Allen Kadado

Surgery Articles

Pediatric osteopetrosis presents a significant technical challenge for fracture fixation due to the bone's dense yet brittle nature and frequently absent medullary canal. Traditional drilling methods risk excessive torque, drill-bit breakage, and iatrogenic fractures. Here, we describe a serial drilling technique for plate-and-screw fixation in a 5-year-old child with osteopetrosis who sustained sequential subtrochanteric femur fractures 8 months apart. By creating a small pilot hole, sequentially enlarging it with intermediate bits under copious irrigation, and inserting locking screws manually, we achieved stable fixation with no observed instrument failure or intraoperative complications. This method may provide a practical technical strategy for …
