Nebraska Center for Virology: Faculty Publications

SARS-CoV-2 belongs to the family Coronaviridae which includes multiple human pathogens that have an outsized impact on aging populations. As a novel human pathogen, SARS-CoV-2 is undergoing continuous adaptation to this new host species and there is evidence of this throughout the scientific and public literature. However, most investigations of SARS-CoV-2 evolution have focused on largescale collections of data across diverse populations and/or living environments. Here we investigate SARS-CoV-2 evolution in epidemiologically linked individuals within a single outbreak at a skilled nursing facility beginning with initial introduction of the pathogen. The data demonstrate that SARSCoV- 2 was introduced to the …

Effectiveness Of An Electronic Health Record Embedded Evidence-Based Testing Algorithm For Clostridioides Difficile Infection., Sarah Marie Bishop

Doctor of Nursing Practice Papers

Background: Clostridioides difficile infection (CDI) commonly impacts hospitalized patients with almost half a million cases reported in the United States annually. C. difficile colonization is more common than infection. Identifying true infection versus colonization is critical to avoiding inappropriate treatment, unnecessary exposure to antibiotics, and increased cost of care. Implementation of evidenced-based CDI testing criteria can help reduce inappropriate CDI testing and avoid the misidentification of colonized patients as true CDI.

Purpose: The purpose of this project was to evaluate the effectiveness of an evidence-based electronic health record (EHR) integrated CDI testing algorithm in reducing inappropriate CDI testing among adult …

Adenocarcinoma Of The Transverse Colon Presenting As Anterior Abdominal Wall Abscess, Jenn Klein, Nima Avin, Sunil Gandhi

HCA Healthcare Journal of Medicine

Introduction

Locally invasive colon carcinoma comprises a small fraction of the incidence of colon carcinoma. Complications, such as perforation and obstruction, can occur in less than 0.5% of cases and often present differently based on location.

Case Presentation

We present a case of an 85-year-old woman who presented with an acute abdominal wall abscess which was caused by perforation of transverse colon carcinoma.

Conclusion

En-bloc resection increases 5-year survival, and adjuvant chemotherapy reduces the risk of recurrence in patients with stage II resectable colon carcinoma.

Escherichia coli is a leading cause of invasive bacterial infections in humans. Capsule polysaccharide has an important role in bacterial pathogenesis, and the K1 capsule has been firmly established as one of the most potent capsule types in E. coli through its association with severe infections. However, little is known about its distribution, evolution and functions across the E. coli phylogeny, which is fundamental to elucidating its role in the expansion of successful lineages. Using systematic surveys of invasive E. coli isolates, we show that the K1-cps locus is present in a quarter of bloodstream infection isolates and has emerged …

Posttreatment Lyme Disease Syndrome And Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Systematic Review And Comparison Of Pathogenesis, Natalie Bai, Christie Richardson

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Lyme disease is the most common vector-borne illness in the United States and has been causing significant morbidity since its discovery in 1977. It is well-documented that about 10% of patients properly treated with antibiotics never fully recover, but instead go on to develop a chronic illness dubbed, posttreatment Lyme disease syndrome (PTLDS) characterized by severe fatigue, cognitive slowing, chronic pain, and sleep difficulties. This review includes 18 studies that detail the symptoms of patients with PTLDS and uses qualitative analysis to compare them to myalgic encephalitis/chronic fatigue syndrome (ME/CFS), a strikingly similar syndrome. In the majority of the PTLDS …

Viral Dna Accumulation Regulates Replication Efficiency Of Chlorovirus Osy-Ne5 In Two Closely Related Chlorella Variabilis Strains, Ahmed Esmael, Irina V. Agarkova, David D. Dunigan, You Zhou, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

Many chloroviruses replicate in Chlorella variabilis algal strains that are ex-endosymbionts isolated from the protozoan Paramecium bursaria, including the NC64A and Syngen 2-3 strains. We noticed that indigenous water samples produced a higher number of plaque-forming viruses on C. variabilis Syngen 2-3 lawns than on C. variabilis NC64A lawns. These observed differences led to the discovery of viruses that replicate exclusively in Syngen 2-3 cells, named Only Syngen (OSy) viruses. Here, we demonstrate that OSy viruses initiate infection in the restricted host NC64A by synthesizing some early virus gene products and that approximately 20% of the cells produce a …


Tenofovir Induced Hypokalaemia - A Case Report, Ankisha Gupta, Kiran P. K, Rajendra Prasad S Jun 2023

Tenofovir Induced Hypokalaemia - A Case Report, Ankisha Gupta, Kiran P. K, Rajendra Prasad S

Digital Journal of Clinical Medicine

Tenofovir, an important medication for HIV/AIDS, carries the risk of hypokalemia in patients receiving treatment. Factors such as dietary deficits, vomiting, or diarrhea further increase this risk. Tenofovir acts as a mitochondrial toxin by inhibiting the DNA polymerase gamma enzyme, crucial for mitochondrial DNA replication. Consequently, ATP generation is depleted through the aerobic pathway, leading to dysfunction in the proximal tubule. This dysfunction manifests as renal acidosis type 2, which involves reduced bicarbonate excretion by the proximal tubule, resulting in renal bicarbonate wasting and decreased serum bicarbonate levels. Consequently, the lumen of the distal nephron becomes negatively charged, leading to …

Candida Auris Screening In The Acute Care Setting: An Infection Control Partnership Between Hospitals And Skilled Nursing Facilities, Brittany S. Thorp Mph, Peggy Brown Mph, Cic, R. Scott Stienecker Md

Infection Control

Presented at 2023 APIC Annual Conference

Background: Candida auris (C. auris) is a drug-resistant fungus that can spread easily between hospitalized patients and nursing home residents. To mitigate risk of C. auris spread, a nine-hospital healthcare system developed a C. auris screening tool in January 2020. Infection Preventionists (IPs) use the screening tool to determine which patients qualify for C. auris screening, looking specifically at the facility type where the patient came from. The IP then initiates the isolation and testing protocol with the bedside nurse and provider.

Methods: Over the course of three years, the hospital epidemiologist collected data …

Methicillin-Resistant Staphylococcus Aureus Screening Of Neonatal Intensive Care Unit Staff In An Outbreak Setting, R. Scott Stienecker Md, Fidsa, Fshea, Cic, Brittany S. Thorp Mph

Infection Control

Presented at 2023 APIC Annual Conference

In December 2020, our infection prevention (IP) department noted an increase in Methicillin-resistant Staphylococcus aureus (MRSA) isolates over baseline in the Neonatal Intensive Care Unit (NICU). Our hospital sees a steady influx of parents colonized with MRSA and our weekly screening process regularly discovers neonates that subsequently become colonized with MRSA. A doubling of the number of cases per month led to deeper investigation. Epidemiologic data were collected on the neonates and matched to their mother’s screening cultures (when obtained). Sensitivity patterns were matched, and staff noted that a single sensitivity pattern predominated

The University of Louisville Journal of Respiratory Infections

Hepatic hydrothorax (HH) is a complication of decompensated liver cirrhosis that only occurs in about 5–6% of cirrhosis patients, defined as a pleural fluid in the setting of known liver disease, with the absence of any other cardiopulmonary etiology. Infected HH is a rare complication, designated as spontaneous bacterial empyema (SBEM), found in only 13–16% of patients with HH. This case follows a patient with SBEM who developed a recurrent pleural effusion minutes after thoracentesis. Our patient is a 56-year-old female with a history of alcoholic cirrhosis with pleuritic pain found to have right-sided pleural effusion with decompensation. She had …

Influenza C virus (ICV) is increasingly associated with community-acquired pneumonia (CAP) in children and its disease severity is worse than the influenza B virus, but similar to influenza A virus associated CAP. Despite the ubiquitous infection landscape of ICV in humans, little is known about its replication and pathobiology in animals. The goal of this study was to understand the replication kinetics, tissue tropism, and pathogenesis of human ICV (huICV) in comparison to the swine influenza D virus (swIDV) in guinea pigs. Intranasal inoculation of both viruses did not cause clinical signs, however, the infected animals shed virus in nasal …
