A Tale Of Two Viruses: Why Smallpox Was Eradicated And Polio Persists, Katherine G. Mcgough, Erin N. Bodine

Spora: A Journal of Biomathematics

The smallpox and poliomyelitis (polio) viruses were, at a time, one of the largest threats to global public health killing millions until global eradication campaigns were put into effect. Vaccination led to the eradication of smallpox and the elimination of polio for most of the world. However, polio continues to persist at endemic levels in Pakistan and Afghanistan. We developed ODE models of smallpox and polio to explore differences in transmission dynamics and determine if the underlying biology has made poliomyelitis more difficult to eradicate. Our model analysis shows there are multiple factors which should allow polio to have a …

BACKGROUND & AIMS: The investigational first-generation core inhibitor vebicorvir (VBR) demonstrated safety and antiviral activity over 24 weeks in two phase IIa studies in patients with chronic HBV infection. In this long-term extension study, patients received open-label VBR with nucleos(t)ide reverse transcriptase inhibitors (NrtIs).

METHODS: Patients in this study (NCT03780543) previously received VBR + NrtI or placebo + NrtI in parent studies 201 (NCT03576066) or 202 (NCT03577171). After receiving VBR + NrtI for ≥52 weeks, stopping criteria (based on the treatment history and hepatitis B e antigen status in the parent studies) were applied, and patients either discontinued both VBR …

Coagulopathy In Severe Covid-19 Patients: Causes, Concerns And Current Treatment Regimen, Tanusree Sengupta, Arun Luiz, Chennakesavan Suganthi, Samarpan Majumder

School of Graduate Studies Faculty Publications

Elevated D-dimer and fibrinogen level, mild thrombocytopenia, modest prolongation of prothrombin time, and activated partial thromboplastin time, are key indicators of coagulopathy, and have been consistently reported in severely ill COVID-19 patients. Coronavirus disease 2019 (COVID-19)-induced coagulopathy can develop serious venous and arterial thromboembolic complications. Endothelial dysfunction and hypercoagulability, triggered mostly by overproduction of inflammatory cytokines as an immune response to the infection, are the pivotal factors responsible for the above-mentioned coagulation disorder. Thus, low-molecular-weight heparin (LMWH), which has both anticoagulant and anti-inflammatory properties, has been reported to improve disease prognosis. However, there have been increasing reports of venous thromboembolic …

Emerging Stroke Risk Factors: A Focus On Infectious And Environmental Determinants, Sajid Hameed, Nurose Karim, Mohammad Wasay, Narayanaswamy Venketasubramanian

Section of Neurology

This review focuses on emerging risk factors for stroke, including air pollution and climate change, gut microbiota, high altitude, and systemic infection. Up to 14% of all stroke-associated mortality is attributed to air pollution and is more pronounced in developing countries. Fine particulate matter and other air pollutants contribute to an increased stroke risk, and this risk appears to increase with higher levels and duration of exposure. Short term air pollution exposure has also been reported to increase the stroke risk. The gut microbiota is a complex ecosystem of bacteria and other microorganisms that reside in the digestive system and …

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) Infection By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4⁺ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing …

Microbial Profile And Antimicrobial Resistance Patterns Of Surgical Intra-Abdominal Infections At A Tertiary Hospital In Tanzania A Retrospective Cross-Sectional Study, Abduel Julius Kitua

Master of Surgery

v>

Among infections of surgical importance, intra-abdominal infections prevail among the most common in surgical patients with considerable morbidity and mortality. The ever-rising microbial resistance to commonly available antibiotics and geographical variations in microbial profile and resistance patterns poses a challenge to the management of these surgical infections of abdominal origin. The aim of this study was to evaluate microbiological characteristics and antibiotic susceptibility of isolates from intra-abdominal infections at a tertiary hospital in Tanzania and how these influence early treatment outcomes.

Factors Associated With Antiretroviral Drug Resistance Mutations Among Plhiv Failing To Achieve Virological Suppression On Second Line Treatment In Tanzania., Mabula M. Mabelele

Master of Internal Medicine

v> Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) is a major public health problem affecting an estimated 38.4 million people globally, with the (54%) of them being from the Eastern and Southern African regions. Despite progress in the availability of multiple classes of antiretroviral drugs and early initiation of treatment with cART, many patients still fail therapy in the first and second-line regimens due to drug resistance driven by continuous acquisition of drug resistance mutation (DRMs). DRMs are high among adults failing treatment regimens, ranging between 50-97%.

Acute Mesenteric Ischemia In Patients With Covid-19, Tristan Fun, Natalie Hurlock, Danielle Ford

North Texas GME Research Forum 2024

Introduction: Patient with COVID-19 are more likely to have thrombotic events, including deep vein thrombosis (DVT), pulmonary embolism (PE), and disseminated intravascular coagulation (DIC). There have been many case reports of patient with acute mesenteric ischemia (AMI) in the setting of COVID-19. Incidences of AMI occur in about 0.1% of acute hospital admissions. Short term mortality from AMI range from 26-86%. Therefore, early diagnosis and treatment are essential, yet diagnosis is difficult and AMI can often go unrecognized as a cause of death. This study attempted to establish the risk of patients with COVID-19 having acute mesenteric ischemia and compare …

Sars-Cov-2 Infectivity, And Interaction With Ace2 In The Human Oral Cavity: A Comprehensive Study, Blake Joseph Henkel

Undergraduate Honors Theses

The oral cavity has the ability to transport infections throughout the body and be infected by bacteria, fungi, protozoa, and viruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus that led to the most recent pandemic. SARS-CoV-2 has unique ways of interacting with the human body to infect individuals, which has led researchers and scientists to have limited knowledge on its long-term impact on human health. However, there are ways to identify various oral cavity infections and prevent infection now and in the future. Many studies have been conducted in an attempt to understand the body’s …

Exploration Of Potential Broad-Spectrum Antiviral Targets In The Enterovirus Replication Element: Identification Of Six Distinct 5' Cloverleaves, Morgan G. Daniels, Meagan E. Werner, Rockwell T. Li, Steven M. Pascal

Chemistry & Biochemistry Faculty Publications

Enterovirus genomic replication initiates at a predicted RNA cloverleaf (5′CL) at the 5′ end of the RNA genome. The 5′CL contains one stem (SA) and three stem-loops (SLB, SLC, SLD). Here, we present an analysis of 5′CL conservation and divergence for 209 human health-related serotypes from the enterovirus genus, including enterovirus and rhinovirus species. Phylogenetic analysis indicates six distinct 5′CL serotypes that only partially correlate with the species definition. Additional findings include that 5′CL sequence conservation is higher between the EV species than between the RV species, the 5′CL of EVA and EVB are nearly identical, and RVC has the …
