Favorable Outcomes With Ventricular Assist Device Exchange, Megan Carroll, Meghan Tooman, Markian Bochan, Christopher Salerno, Ashwin Ravichandran 2019 Indiana University School of Medicine

Favorable Outcomes With Ventricular Assist Device Exchange, Megan Carroll, Meghan Tooman, Markian Bochan, Christopher Salerno, Ashwin Ravichandran

The VAD Journal

Left ventricular assist device (LVAD) therapy remains a vital therapeutic option for patients with end-stage heart failure. Unfortunately, adverse events can occur and progress to require consideration for device exchange once the failure of medical management becomes evident, especially when heart transplantation is not possible in a timely manner. The aim of this analysis is to describe the incidence and outcomes of LVAD exchanges at our institution. Between April 2008 and May 2017, 397 patients underwent LVAD implantation, with 32 of those patients subsequently receiving exchange upon the recommendation of our multidisciplinary team due to refractory infection (n=12), device ...

Mucormycosis - Dual Therapy With Prolonged Survival, Maydelin Pecchio, Yariela Osabio, Yariela Morales, Forest W. Arnold

Journal of Refugee & Global Health

Mucorales fungal infection is a fungal disease with potentially fatal outcomes. The most frequent involvement in humans comes from the orders known as Mucorales and Entomophthorales. Mucorales is more acute and has a predilection for immunocompromised patients. Mucorales are associated with an affinity for vessels, which leads to invasion and infarction of tissue. Mucormycosis is a devastating complication that can be a life threatening fungal invasion in many patients in an immunocompromised state.

Severity Of Disease And Mortality For Hospitalized Patients With Community-Acquired Viral Pneumonia Compared To Patients With Community-Acquired Bacterial Pneumonia, Richard Y. Kim, Thomas Chandler, Stephen P. Furmanek, Timothy Lee Wiemken, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Background: There exists a large body of literature to help identify, diagnose, treat, and manage community-acquired pneumonia (CAP). Despite this, there is little data that directly compares the clinical syndromes and complications of pure bacterial pneumonia to pure viral pneumonia. Our study compares the clinical presentation, morbidity and mortality of viral vs. bacterial etiologies of CAP.

Methods: This was a secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) international study database. Data was collected concerning patient demographics, physical examination findings, laboratory findings, radiological findings, severity of illness, and clinical outcomes and stratified according to the two study groups, CAVP ...

Persistent Viral Reservoirs In Lymphoid Tissues In Siv-Infected Rhesus Macaques Of Chinese-Origin On Suppressive Antiretroviral Therapy, Summer Siddiqui, Stefanie Perez, Yong Gao, Lara Doyle-Meyers, Brian T. Foley, Qingsheng Li, Binhua Ling

Virology Papers

Understanding HIV latent reservoirs in tissues is essential for the development of new strategies targeting these sites for eradication. Here, we assessed the size of latent reservoirs and the source of residual viruses in multiple lymphoid tissues of SIV-infected and fully suppressed rhesus macaques of Chinese-origin (cRMs). Eight cRMs were infected with SIVmac251 and treated with tenofovir and emtricitabine daily for 24 weeks initiated 4 weeks post-infection. Four of the eight animals reached sustained full viral suppression with undetectable viremia. The levels of cell-associated SIV DNA varied in peripheral blood mononuclear cells (PBMCs) and multiple lymphoid tissues, but with higher ...

Virology Papers

Nearly all cervical cancers are causally associated with human papillomavirus (HPV). The burden of HPV-associated dysplasias in sub-Saharan Africa is influenced by HIV. To investigate the role of the bacterial microbiome in cervical dysplasia, cytobrush samples were collected directly from cervical lesions of 144 Tanzanian women. The V4 hypervariable region of the 16S rRNA gene was amplified and deep sequenced. Alpha diversity metrics (Chao1, PD whole tree, and operational taxonomic unit [OTU] estimates) displayed significantly higher bacterial richness in HIV-positive patients (P = 0.01) than in HIV-negative patients. In HIV-positive patients, there was higher bacterial richness in patients with high-grade ...

Virology Papers

Although the nucleocytoplasmic large DNA viruses (NCLDVs) are one of the largest group of viruses that infect many eukaryotic hosts, the near-atomic resolution structures of these viruses have remained unknown. Here we describe a 3.5 Å resolution icosahedrally averaged capsid structure of Paramecium bursaria chlorella virus 1 (PBCV-1). This structure consists of 5040 copies of the major capsid protein, 60 copies of the penton protein and 1800 minor capsid proteins of which there are 13 different types. The minor capsid proteins form a hexagonal network below the outer capsid shell, stabilizing the capsid by binding neighboring capsomers together. The ...


A Poxvirus Pseudokinase Represses Viral Dna Replication Via A Pathway Antagonized By Its Paralog Kinase, Annabel T. Olson, Zhigang Wang, Amber B. Rico, Matthew S. Wiebe 2019 University of Nebraska - Lincoln

A Poxvirus Pseudokinase Represses Viral Dna Replication Via A Pathway Antagonized By Its Paralog Kinase, Annabel T. Olson, Zhigang Wang, Amber B. Rico, Matthew S. Wiebe

Virology Papers

Poxviruses employ sophisticated, but incompletely understood, signaling pathways that engage cellular defense mechanisms and simultaneously ensure viral factors are modulated properly. For example, the vaccinia B1 protein kinase plays a vital role in inactivating the cellular antiviral factor BAF, and likely orchestrates other pathways as well. In this study, we utilized experimental evolution of a B1 deletion virus to perform an unbiased search for suppressor mutations and identify novel pathways involving B1. After several passages of the ΔB1 virus we observed a robust increase in viral titer of the adapted virus. Interestingly, our characterization of the adapted viruses reveals that ...

BACKGROUND: Hyperendemic circulation of all four types of dengue virus (DENV-1-4) has expanded globally, fueling concern for increased incidence of severe dengue. While the majority of DENV infections are subclinical, epidemiologic studies suggest that type-cross-reactive immunity can influence disease outcome in subsequent infections. The mechanisms controlling these differential clinical outcomes remain poorly defined.

METHODOLOGY/PRINCIPAL FINDINGS: Blood samples were collected from a cohort of school-aged Thai children who subsequently experienced a subclinical DENV infection or developed dengue illness. PBMC collected prior to infection were stimulated in vitro with DENV and the secretion of 30 cytokines was measured using a multiplexed ...

Non-Neutralizing Antibodies Elicited By Recombinant Lassa-Rabies Vaccine Are Critical For Protection Against Lassa Fever., Tiago Abreu-Mota, Katie R. Hagen, Kurt Cooper, Peter B. Jahrling, Gene Tan, Christoph Wirblich, Reed F. Johnson, Matthias J. Schnell

Department of Microbiology and Immunology Faculty Papers

Lassa fever (LF), caused by Lassa virus (LASV), is a viral hemorrhagic fever for which no approved vaccine or potent antiviral treatment is available. LF is a WHO priority disease and, together with rabies, a major health burden in West Africa. Here we present the development and characterization of an inactivated recombinant LASV and rabies vaccine candidate (LASSARAB) that expresses a codon-optimized LASV glycoprotein (coGPC) and is adjuvanted by a TLR-4 agonist (GLA-SE). LASSARAB elicits lasting humoral response against LASV and RABV in both mouse and guinea pig models, and it protects both guinea pigs and mice against LF. We ...

Characterizing The Gut Microbiota During Plasmodium Infection And Antimalarial Treatment., Joshua E. Denny

Electronic Theses and Dissertations

Plasmodium, the parasitic cause of malaria, is a global pathogen, annually causing 216 million infections and 445,000 deaths. As drug resistance continues develop and no effective vaccine is available, it is critical to understand the factors underlying the severity of this disease. Plasmodium is an extra-gastrointestinal tract infection where the parasite infects red blood cells causing clinical malaria. However, recent publications have pointed to interactions between the gut microbiota and malaria. With this in mind, the role of the gut microbiota in malaria infection was studied. C57BL/6 mice from different vendors displayed differential resistance and susceptibility to severe ...
