The addition of cladribine, or sorafenib to standard chemotherapy have each demonstrated improved survival in patients with newly-diagnosed acute myeloid leukemia (AML). We studied the combination of cladribine, idarubicin, and intermediate-dose cytarabine (CLIA) in patients ≤65 years of age with newly diagnosed AML, fit to receive intensive therapy. Cladribine (5 mg/m2) IV was administered on days (D)1-5, cytarabine (1 g/m2) on D1-5, and idarubicin (10 mg/m2) on D1-3. Sorafenib was added to the CLIA backbone for patients with FLT3-ITD mutated AML. 80 patients were enrolled: 65 with newly diagnosed AML and 15 with AML arising from previously treated MDS (ts-AML). …

Mitochondrial Health Index Correlates With Plasma Circulating Cell-Free Mitochondrial Dna In Bipolar Disorder, Rafaela C Cordeiro, Camila N C Lima, Gabriel R Fries, Giovana Zunta-Soares, Jair C Soares, João Quevedo, Giselli Scaini

Faculty, Staff and Student Publications

Although mitochondrial dysfunction is known to play an essential role in the pathophysiology of bipolar disorder (BD), there is a glaring gap in our understanding of how mitochondrial dysfunction can modulate clinical phenotypes. An emerging paradigm suggests mitochondria play an important non-energetic role in adaptation to stress, impacting cellular resilience and acting as a source of systemic allostatic load. Known as mitochondrial allostatic load, this (phenomenon) occurs when mitochondria are unable to recalibrate and maintain cell homeostasis. This study aimed to evaluate the composite mitochondrial health index (MHI) in BD subjects and non-psychiatry controls. We will also explore whether lower …

A Case Report Of Anesthesia-Induced Diffuse Alveolar Hemorrhage Presenting To The Emergency Department, Daniel Yiu, Christopher Stephens, Jacquelyn Mccullough, Lesley Osborn

Faculty, Staff and Student Publications

Introduction: The inhaled anesthetic sevoflurane is an uncommon etiology of diffuse alveolar hemorrhage (DAH). As DAH typically presents in the inpatient, postoperative setting, it has been infrequently reported in the anesthesiology literature and, to our knowledge, has not been reported in the emergency medicine literature to date.

Case report: We describe the presentation of a young, healthy male in respiratory distress to a busy urban emergency department (ED) after an outpatient surgical procedure. We highlight the etiology of post-anesthesia DAH and the acute management of this rare diagnosis in the ED.

Conclusion: With outpatient surgical centers becoming an increasingly popular …

Optogenetic Stimulation Of Ca1 Pyramidal Neurons At Theta Enhances Recognition Memory In Brain Injured Animals, John I Broussard, John B Redell, Jing Zhao, Rebecca West, Ryota Homma, Pramod K Dash

Faculty, Staff and Student Publications

The hippocampus plays a prominent role in learning and memory formation. The functional integrity of this structure is often compromised after traumatic brain injury (TBI), resulting in lasting cognitive dysfunction. The activity of hippocampal neurons, particularly place cells, is coordinated by local theta oscillations. Previous studies aimed at examining hippocampal theta oscillations after experimental TBI have reported disparate findings. Using a diffuse brain injury model, the lateral fluid percussion injury (FPI; 2.0 atm), we report a significant reduction in hippocampal theta power that persists for at least three weeks after injury. We questioned whether the behavioral deficit associated with this …

Design And Development Of A Clot Burst Pressure Device To Investigate Resuscitation Strategies, Atharwa R Mankame, Jacob B Schriner, Max A Skibber, Mitchell J George, Jessica C Cardenas, Charles S Cox, Brijesh S Gill

Faculty, Staff and Student Publications

Introduction: A reduction in clot strength is a hallmark feature of trauma-induced coagulopathy. A better understanding of clot integrity can optimize resuscitation strategies. We designed a device to gauge clot strength by pressurizing fluids over a formed clot and measuring the pressure needed to dislodge the clot. We hypothesized that this device could distinguish between clots formed in hypocoagulable and hypercoagulable states by observing differences in the clot burst pressure.

Methods: Whole blood from healthy volunteers was collected into sodium citrate tubes and was treated with heparin or fibrinogen to generate clots in a hypocoagulable or hypercoagulable state, respectively. Small …

Severe Lupus Enteritis Complicated By Intractable Gastrointestinal Hemorrhage, Austin Thomas, Clay Smithhart, Maneera Chopra, Athira Jayan, Faisal Ali, Karim Doughem, Asmeen Bhatt, Joanna Scoon, Scott Larson

Faculty, Staff and Student Publications

Lupus enteritis (LE) is a rare presentation of systemic lupus erythematosus manifesting with nonspecific symptoms, laboratory derangements, and imaging findings. Rarely, LE may progress to bowel perforation, hemorrhage, and even death. Treatment with systemic glucocorticoids often results in rapid clinical improvement, but patients may require further immunosuppression. We present a case of severe LE complicated by life-threatening intractable gastrointestinal hemorrhage and warm autoimmune hemolytic anemia refractory to glucocorticoids and ultimately requiring massive transfusions, intravenous immunoglobulin, and plasmapheresis. This case illustrates the importance of early specialist involvement and treatment with intravenous immunoglobulin and plasmapheresis for severe, life-threatening LE.

Understanding And Managing Anxiety Sensitivity During Critical Illness And Long-Term Recovery, Leanne M Boehm, Claire M Bird, Ann Marie Warren, Valerie Danesh, Megan M Hosey, Joanne Mcpeake, Kelly M Potter, Han Su, Tammy L Eaton, Mark B Powers

Faculty, Staff and Students Publications

Anxiety sensitivity is a fear of symptoms associated with anxiety (eg, rapid respiration and heart rate, perspiration), also known as "fear of fear." This fear is a misinterpretation of nonthreatening symptoms as threatening across 3 domains: physical ("When my heart rate increases, I'm afraid I may have a heart attack"), social ("If people see me perspire, I fear they will negatively evaluate me"), and cognitive ("When I feel these symptoms, I fear it means I'm going crazy or will lose control and do something dangerous like disconnect my IV"). These thoughts stimulate the sympathetic nervous system, resulting in stronger sensations …

Dynamic contrast-enhanced MR imaging (DCE-MRI) can assess the integrity of the blood brain barrier (BBB) and has been used in GBM patients to determine glioma grade, predict prognosis, evaluate treatment response, and differentiate treatment-induced effect from recurrence. The volume transfer constant Ktrans is the most frequently used metric in tumor assessment. Based on previous studies that a higher WHO grade of brain tumor was associated with greater impairments of immunity and and that Ktrans value was associated with the pathological grading, the relationship between differential composition of immune cells in GBM tissue and dynamic changes in Ktrans mapping was anticipated …

Real-Time Liver Motion Estimation Via Deep Learning-Based Angle-Agnostic X-Ray Imaging, Hua-Chieh Shao, Yunxiang Li, Jing Wang, Steve Jiang, You Zhang

Faculty, Staff and Student Publications

Background: Real-time liver imaging is challenged by the short imaging time (within hundreds of milliseconds) to meet the temporal constraint posted by rapid patient breathing, resulting in extreme under-sampling for desired 3D imaging. Deep learning (DL)-based real-time imaging/motion estimation techniques are emerging as promising solutions, which can use a single X-ray projection to estimate 3D moving liver volumes by solved deformable motion. However, such techniques were mostly developed for a specific, fixed X-ray projection angle, thereby impractical to verify and guide arc-based radiotherapy with continuous gantry rotation.

Purpose: To enable deformable motion estimation and 3D liver imaging from individual X-ray …

Biomechanics In The Onset And Severity Of Spondyloarthritis: A Force To Be Reckoned With, Priyanka Iyer, Mark Hwang, Lauren Ridley, Michael M Weisman

Faculty, Staff and Student Publications

Increasing evidence suggests that there is a pivotal role for physical force (mechanotransduction) in the initiation and/or the perpetuation of spondyloarthritis; the review contained herein examines that evidence. Furthermore, we know that damage and inflammation can limit spinal mobility, but is there a cycle created by altered spinal mobility leading to additional damage and inflammation?Over the past several years, mechanotransduction, the mechanism by which mechanical perturbation influences gene expression and cellular behaviour, has recently gained popularity because of emerging data from both animal models and human studies of the pathogenesis of ankylosing spondylitis (AS). In this review, we provide evidence …

BACKGROUND: Neuroendocrine phenotype is commonly associated with therapy resistance and poor prognoses in small-cell neuroendocrine cancers (SCNCs), such as neuroendocrine prostate cancer (NEPC) and small-cell lung cancer (SCLC). Expression levels of current neuroendocrine markers exhibit high case-by-case variability, so multiple markers are used in combination to identify SCNCs. Here, we report that ACAA2 is elevated in SCNCs and is a potential molecular indicator for SCNCs.

METHODS: ACAA2 expressions in tumour xenografts, tissue microarrays (TMAs), and patient tissues from prostate and lung cancers were analysed via immunohistochemistry. ACAA2 mRNA levels in lung and prostate cancer (PC) patients were assessed in published …

Faculty, Staff and Student Publications

Arginase deficiency (ARG1‐D) is an autosomal recessive inborn error of metabolism that is often misdiagnosed. Classic presentation of ARG1‐D includes progressive symptoms of spasticity, delayed development, cognitive impairment, protein avoidance, and seizures. Patients who present atypically may evade diagnosis and require a thoughtful diagnostic workup. Here, we discuss three females of Latin American origin with differing clinical presentations, but who all have the same intronic pathogenic variant in ARG1. Importantly, we found that each case included elevated coagulopathy on laboratory testing and discussed one case in particular with manifestation of bleeding. When diagnosed early, treatment is favorable and can …
