Vaccine Confidence, Coverage, And Hesitancy Worldwide: A Literature Analysis Of Vaccine Hesitancy And Potential Causes Worldwide, Jordan Hammond Apr 2020

Vaccine Confidence, Coverage, And Hesitancy Worldwide: A Literature Analysis Of Vaccine Hesitancy And Potential Causes Worldwide, Jordan Hammond

Senior Theses

Vaccines are one of the world’s most impactful medical therapies. They are cost-effective, successfully proven, and one of the quickest treatment options available today (Clark et al., 2016). They save millions of lives every year and have eliminated certain diseases on a national and international level. However, millions of people worldwide still remain unvaccinated. In developed nations, mainly The United States (U.S.) and the European countries, many of the unvaccinated are a result of rising vaccine hesitancy of parents in conjunction with the anti-vaccination movement. Vaccine hesitancy is defined as “a delay in acceptance or refusal of vaccines despite availability” …

Background and aims: Sulfur-metabolizing microbes, which convert dietary sources of sulfur into genotoxic hydrogen sulfide (H2S), have been associated with development of colorectal cancer (CRC). We identified a dietary pattern associated with sulfur-metabolizing bacteria in stool and then investigated its association with risk of incident CRC using data from a large prospective study of men.

Methods: We collected data from 51,529 men enrolled in the Health Professionals Follow-up Study since 1986 to determine the association between sulfur-metabolizing bacteria in stool and risk of CRC over 26 years of follow-up. First, in a subcohort of 307 healthy men, we …


Unraveling Molecular Mechanisms Underlying The Development Of Unconventional T Cells, Daniel Eduardo Bastardo Blanco Apr 2020

Unraveling Molecular Mechanisms Underlying The Development Of Unconventional T Cells, Daniel Eduardo Bastardo Blanco

Theses and Dissertations (ETD)

The thymus supports and guides the generation of a diverse repertoire of mature T cells from precursors derived from the bone marrow. In addition to conventional CD4 and CD8 T cells, innate-like T cells also develop in the thymus and share features of the adaptive and the innate immune system. These ‘unconventional’ T cells have emerging roles in tissue homeostasis and disease, but the molecular mechanisms underpinning their development remain elusive. In this study, we uncovered the roles of the molecules RAPTOR and PTEN in the thymic development of unconventional T cells. Capitalizing on genetic deletion of RAPTOR, we found …

BACKGROUND & AIMS: Direct-acting antivirals (DAAs) are effective against hepatitis C virus and sustained virologic response is associated with reduced incidence of hepatocellular carcinoma (HCC). However, there is controversy over the use of DAAs in patients with active or treated HCC and uncertainty about optimal management of these patients. We aimed to characterize attitudes and practice patterns of hepatology practitioners in the United States regarding the use of DAAs in patients with HCC.

METHODS: We conducted a survey of hepatology providers at 47 tertiary care centers in 25 states. Surveys were sent to 476 providers and we received 279 responses …


Elucidating The Regulon Of A Fur-Like Protein In Mycobacterium Avium Subsp. Paratuberculosis (Map), Fernanda Miyagaki Shoyama, Taveesak Janetanakit, John P. Bannantine, Raul G. Barletta, Srinand Sreevatsan Apr 2020

Nebraska Center for Virology: Faculty Publications

Intracellular iron concentration is tightly regulated to maintain cell viability. Iron plays important roles in electron transport, nucleic acid synthesis, and oxidative stress. A Mycobacterium avium subsp. paratuberculosis (MAP)-specific genomic island carries a putative metal transport operon that includes MAP3773c, which encodes a Fur-like protein. Although well characterized as a global regulator of iron homeostasis in multiple bacteria, the function of Fur (ferric uptake regulator) in MAP is unknown as this organism also carries IdeR (iron dependent regulator), a native iron regulatory protein specific to mycobacteria. Computational analysis using PRODORIC identified 23 different pathways involved in respiration, metabolism, and virulence …

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area …


Approaches To Overcome Flow Cytometry Limitations In The Analysis Of Cells From Veterinary Relevant Species, Julia Hunka, John T. Riley, Gudrun F. Debes Mar 2020

Approaches To Overcome Flow Cytometry Limitations In The Analysis Of Cells From Veterinary Relevant Species, Julia Hunka, John T. Riley, Gudrun F. Debes

Department of Microbiology and Immunology Faculty Papers

BACKGROUND: Flow cytometry is a powerful tool for the multiparameter analysis of leukocyte subsets on the single cell level. Recent advances have greatly increased the number of fluorochrome-labeled antibodies in flow cytometry. In particular, an increase in available fluorochromes with distinct excitation and emission spectra combined with novel multicolor flow cytometers with several lasers have enhanced the generation of multidimensional expression data for leukocytes and other cell types. However, these advances have mainly benefited the analysis of human or mouse cell samples given the lack of reagents for most animal species. The flow cytometric analysis of important veterinary, agricultural, wildlife, …

von Economo neurons (VENs) are bipolar, spindle-shaped neurons restricted to layer 5 of human frontoinsula and anterior cingulate cortex that appear to be selectively vulnerable to neuropsychiatric and neurodegenerative diseases, although little is known about other VEN cellular phenotypes. Single nucleus RNA-sequencing of frontoinsula layer 5 identifies a transcriptomically-defined cell cluster that contained VENs, but also fork cells and a subset of pyramidal neurons. Cross-species alignment of this cell cluster with a well-annotated mouse classification shows strong homology to extratelencephalic (ET) excitatory neurons that project to subcerebral targets. This cluster also shows strong homology to a putative ET cluster in …

Objective The purpose of this study was to assess the efficacy of the addition of clarithromycin to the ventilator care bundle to help in the prevention of ventilator-associated pneumonia (VAP). Patients and methods Eighty patients of more than 18 years, on a mechanical ventilator for less than 48 h, expected length of stay in the ICU for more than 48 h, with no clinical and radiographic evidence of pneumonia were enrolled in a double-blind comparative study. The patients were randomized to one of the two groups: group A (n = 40) where the patients received clarithromycin (through the Ryle …


Probable African Tick Bite Fever In The United States, Kami Lowery, Theodore Rosen Mar 2020

Probable African Tick Bite Fever In The United States, Kami Lowery, Theodore Rosen

Faculty, Staff and Students Publications

African tick bite fever (ATBF) is a tick-borne rickettsial disease most often observed in North American and European tourists returning home from the southern portion of Africa. Ticks infected with Rickettsia africae transmit this parasitic bacterium to humans, who subsequently develop an influenza-like illness, one or more inoculation eschars, and in some cases, a cutaneous rash. Because ATBF often presents with non-specific symptoms that suggest other infectious diseases, establishing the diagnosis may be difficult. Confirmatory assays, including serology and nucleic acid amplification, may take weeks to return and cannot help with acute treatment decisions. We present a case of a …

Eliciting protective titers of HIV-1 broadly neutralizing antibodies (bnAbs) is a goal of HIV-1 vaccine development, but current vaccine strategies have yet to induce bnAbs in humans. Many bnAbs isolated from HIV-1-infected individuals are encoded by immunoglobulin gene rearrangments with infrequent naive B cell precursors and with unusual genetic features that may be subject to host regulatory control. Here, we administer antibodies targeting immune cell regulatory receptors CTLA-4, PD-1 or OX40 along with HIV envelope (Env) vaccines to rhesus macaques and bnAb immunoglobulin knock-in (KI) mice expressing diverse precursors of CD4 binding site HIV-1 bnAbs. CTLA-4 blockade augments HIV-1 Env …

BACKGROUND: The development of an in vitro cultivation system for human noroviruses allows the measurement of neutralizing antibody levels.

METHODS: Serum neutralizing antibody levels were determined using a GII.4/Sydney/2012-like virus in human intestinal enteroids in samples collected before and 4 weeks after administration of an investigational norovirus vaccine and were compared with those measured in histo-blood group antigen (HBGA)-blocking assays.

RESULTS: Neutralizing antibody seroresponses were observed in 71% of 24 vaccinated adults, and antibody levels were highly correlated (r = 0.82, P < .001) with those measured by HBGA blocking.

CONCLUSIONS: HBGA-blocking antibodies are a surrogate for neutralization in human noroviruses.

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Intraperitoneal vancomycin is the first-line therapy in the management of peritoneal dialysis (PD)-related peritonitis. However, due to the paucity of data, vancomycin dosing for peritonitis in patients on automated peritoneal dialysis (APD) is empiric and based on clinical experience rather than evidence. Studies in continuous ambulatory peritoneal dialysis (CAPD) patients have been used to provide guidelines for dosing and are often extrapolated for APD use, but it is unclear whether this is appropriate. This review summarizes the available pharmacokinetic data used to inform optimal dosing in patients on CAPD or APD. The determinants of vancomycin disposition and pharmacodynamic effects are …

Characterization Of A Species E Adenovirus Vector As A Zika Virus Vaccine, Brianna L. Bullard, Brigette N. Corder, David N. Gordon, Theodore C. Pierson, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

The development of a safe and efficacious Zika virus (ZIKV) vaccine remains a global health priority. In our previous work, we developed an Adenovirus vectored ZIKV vaccine using a low-seroprevalent human Adenovirus type 4 (Ad4-prM-E) and compared it to an Ad5 vector (Ad5-prM-E). We found that vaccination with Ad4-prM-E leads to the development of a strong anti-ZIKV T-cell response without eliciting significant anti-ZIKV antibodies, while vaccination with Ad5-prM-E leads to the development of both anti-ZIKV antibody and T-cell responses in C57BL/6 mice. However, both vectors conferred protection against ZIKV infection in a lethal challenge model. Here we continued to characterize …

Small-molecule inhibitors of translation are critical tools to study the molecular mechanisms of protein synthesis. In this study, we sought to characterize how QL47, a host-targeted, small-molecule antiviral agent, inhibits steady-state viral protein expression. We demonstrate that this small molecule broadly inhibits both viral and host protein synthesis and targets a translation step specific to eukaryotic cells. We show that QL47 inhibits protein neosynthesis initiated by both canonical cap-driven and noncanonical initiation strategies, most likely by targeting an early step in translation elongation. Our findings thus establish QL47 as a new small-molecule inhibitor that can be utilized to probe the …

Social interactions are critically important for survival and impact overall-health, but also impose costs on animals, such as exposure to contagious agents. The immune system can play a critical role in modulating social behavior when animals are sick, as has been demonstrated within the context of “sickness behaviors.” Can immune molecules affect or be affected by social interactions even when animals are not sick, therefore serving a role in mediating pathogen exposure? We tested whether markers of immune function in both the blood and the brain are associated with gregariousness, quantified as number of animals interacted with per day. To …

Cryptococcal Antigen Testing In An Integrated Medical System: Eastern Wisconsin, Marianne Klumph, Brian Hoeynck, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Cryptococcosis is a serious environmentally acquired endemic fungal infection commonly associated with immunocompromised hosts. Little is known regarding frequency or distribution in Wisconsin. We explored the geodemographic and clinical features of patients tested with cryptococcal antigen tests (CrAg) — previously shown to be >90% sensitive and >90% specific — within a large health care system located in eastern Wisconsin. To examine this, we retrospectively analyzed 1465 CrAg tests on 1211 unique patients (female: 50.2%; white race: 73.9%; mean age: 53.7 ± 16.5 years). At least one CrAg result was positive in 23 of 1211 patients (1.9%). From these, 21 of …

The prognosis of chronic lymphocytic leukemia (CLL) depends on different markers, including cytogenetic aberrations, oncogenic mutations, and mutational status of the immunoglobulin (Ig) heavy-chain variable (IGHV) gene. The number of IGHV mutations distinguishes mutated (M) CLL with a markedly superior prognosis from unmutated (UM) CLL cases. In addition, B cell antigen receptor (BCR) stereotypes as defined by IGHV usage and complementaritydetermining regions (CDRs) classify ∼30% of CLL cases into prognostically important subsets.

Lupus nephritis, one of the most serious manifestations of systemic lupus erythematosus (SLE), has both a heterogeneous clinical and pathological presentation. For example, proliferative nephritis identifies a more aggressive disease class that requires immunosuppression. However, the current classification system relies on the static appearance of histopathological morphology which does not capture differences in the inflammatory response. Therefore, a biomarker grounded in the disease biology is needed to understand the molecular heterogeneity of lupus nephritis and identify immunologic mechanism and pathways. Here, we analyzed the patterns of 1000 urine protein biomarkers in 30 patients with active lupus nephritis. We found that …
