OBJECTIVES: To assess the in vitro IntelliSep test, a microfluidic assay that quantifies the state of immune activation by evaluating the biophysical properties of leukocytes, as a rapid diagnostic for sepsis. DESIGN: Prospective cohort study. SETTING: Five emergency departments (EDs) in Louisiana, Missouri, North Carolina, and Washington. PATIENTS: Adult patients presenting to the ED with signs (two of four Systemic Inflammatory Response Syndrome criteria, where one must be temperature or WBC count) or suspicion (provider-ordered culture) of infection. INTERVENTIONS: All patients underwent testing with the IntelliSep using ethylene diamine tetraacetic acid-anticoagulated whole blood followed by retrospective adjudication for sepsis by …

Substance use disorders have been associated with alterations in the oxytocinergic system, but few studies have investigated both the peptide and epigenetic mechanisms potentially implicated in the regulation of oxytocin receptor. In this study, we compared plasma oxytocin and blood DNA methylation in the OXTR gene between people with and without cocaine use disorder (CUD). We measured the oxytocin levels of 51 people with CUD during acute abstinence and of 30 healthy controls using an enzyme immunoassay. The levels of DNA methylation in four CpG sites at exon III of the OXTR gene were evaluated in a subsample using pyrosequencing. …

Recently, it has been suggested that central and peripheral toxicities identified in persons with substance use disorder (SUD) could be partially associated with an imbalance in reactive oxygen species and antioxidant defenses. We conducted a systematic review and meta-analysis to investigate whether SUD is associated with oxidative stress and to identify biomarkers possibly more affected by this condition. We have included studies that analysed oxidant and antioxidant markers in individuals with SUD caused by stimulants, alcohol, nicotine, opioids, and others (cannabis, inhalants, and polysubstance use). Our analysis showed that persons with SUD show higher oxidant markers and lower antioxidant markers …

Objective Assess the IntelliSep Index (ISI) for risk stratification of patients presenting to the Emergency Department (ED) with respiratory symptoms suspected of COVID-19 during the pandemic. Methods An observational single-center study of prospective cohort of patients presenting to the ED during the early COVID-19 pandemic with respiratory symptoms and a CBC drawn within 4.5 hours of initial vital signs. A sample of this blood was aliquoted for performance of the ISI, and patients were followed for clinical outcomes. The study required no patient-centered activity beyond standard of care and treating clinicians were unaware of study enrollment and ISI test results. …


Landscape Of Molecular Crosstalk Perturbation Between Lung Cancer And Covid-19, Aditi Kuchi, Jiande Wu, Jyotsna Fuloria, Chindo Hicks Mar 2022

Landscape Of Molecular Crosstalk Perturbation Between Lung Cancer And Covid-19, Aditi Kuchi, Jiande Wu, Jyotsna Fuloria, Chindo Hicks

School of Medicine Faculty Publications

Background: Lung cancer patients have the worst outcomes when affected by coronavirus disease 2019 (COVID-19). The molecular mechanisms underlying the association between lung cancer and COVID-19 remain unknown. The objective of this investigation was to determine whether there is crosstalk in molecular perturbation between COVID-19 and lung cancer, and to identify a molecular signature, molecular networks and signaling pathways shared by the two diseases. Methods: We analyzed publicly available gene expression data from 52 severely affected COVID-19 human lung samples, 594 lung tumor samples and 54 normal disease-free lung samples. We performed network and pathways analysis to identify molecular networks …

School of Medicine Faculty Publications

Angiotensin-converting enzyme 2 (ACE2) has been identified as the host entry receptor for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the COVID-19 pandemic. ACE2 is a regulatory enzyme of the renin-angiotensin system and has protective functions in many cardiovascular, pulmonary and metabolic diseases. This review summarizes available murine models with systemic or organ-specific deletion of ACE2, or with overexpression of murine or human ACE2. The purpose of this review is to provide researchers with the genetic tools available for further understanding of ACE2 biology and for the investigation of ACE2 in the pathogenesis and treatment of COVID-19.


Acute Exacerbations Of Chronic Obstructive Pulmonary Disease: A Primer For Emergency Physicians, Randy Sorge, Peter Deblieux Sep 2020

Acute Exacerbations Of Chronic Obstructive Pulmonary Disease: A Primer For Emergency Physicians, Randy Sorge, Peter Deblieux

School of Medicine Faculty Publications

Background: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) impose a significant burden on patients and the emergency health care system. Patients with COPD who present to the emergency department (ED) often have comorbidities that can complicate their management. Objective: To discuss strategies for the management of acute exacerbations in the ED, from initial assessment through disposition, to enable effective patient care and minimize the risk of treatment failure and prevent hospital readmissions. Discussion: Establishing a correct diagnosis early on is critical; therefore, initial evaluations should be aimed at differentiating COPD exacerbations from other life-threatening conditions. Disposition decisions are based …


Exogenous Lipoid Pneumonia Complicated By Mineral Oil Asperation In A Patient With Chronic Constipation: A Case Report And Review, Hafiz Muhammad Jeelani, Muhammad Mubbashir Sheikh, Belaal Sheikh, Hafiz Mahboob, Anchit Bharat Jul 2020

Exogenous Lipoid Pneumonia Complicated By Mineral Oil Asperation In A Patient With Chronic Constipation: A Case Report And Review, Hafiz Muhammad Jeelani, Muhammad Mubbashir Sheikh, Belaal Sheikh, Hafiz Mahboob, Anchit Bharat

Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of …


Recent Advances In Understanding And Management Of Bronchopulmonary Dysplasia, Vineet Bhandari, Mitali Sahni Jan 2020

Recent Advances In Understanding And Management Of Bronchopulmonary Dysplasia, Vineet Bhandari, Mitali Sahni

School of Medicine Faculty Publications

© 2020 Sahni M and Bhandari V. In the current era, the survival of extremely low-birth-weight infants has increased considerably because of new advances in technology; however, these infants often develop chronic dysfunction of the lung, which is called bronchopulmonary dysplasia (BPD). BPD remains an important cause of neonatal mortality and morbidity despite newer and gentler modes of ventilation. BPD results from the exposure of immature lungs to various antenatal and postnatal factors that lead to an impairment in lung development and aberrant growth of lung parenchyma and vasculature. However, we still struggle with a uniform definition for BPD that …

Introduction: Computed tomography pulmonary angiography (CTPA) is the test of choice for diagnosis of pulmonary embolism (PE) in the emergency department (ED), but this test may be indeterminate for technical reasons such as inadequate contrast filling of the pulmonary arteries. Many hospitals have requirements for intravenous (IV) catheter size or location for CTPAs to reduce the chances of inadequate filling, but there is a lack of clinical data to support these requirements. The objective of this study was to determine if a certain size or location of IV catheter used for contrast for CTPA is associated with an increased chance …
