Creation Of An Influenza A Virus Neuraminidase Consensus Vaccine In An Adenoviral Vector, Leigh Jahnke

Honors Program: Senior Projects (Public)

In the last decade, the estimated annual burden of the flu includes 12,000-52,000 deaths, 140,000-710,000 hospitalizations, and 9 million – 41 million illnesses (Centers for Disease Control and Prevention: Disease burden of the flu). Influenza A virus can mutate and infect a variety of different hosts, which results in frequent antigenic changes and even pandemics. This has led to increased attention on the creation of a universal Influenza A vaccine containing broader immunogenic coverage than current vaccines. Our research involved detailing the steps of the cloning process utilizing a consensus neuraminidase antigen. We utilized the pAdEasy Adenoviral Vector …

Pulmonary Post-Acute Sequelae Of Covid-19, Usman Akbar, Shivam Gulati, Johnny Zakhour Md, Alex Glynn, Jose Bordon

The University of Louisville Journal of Respiratory Infections

Introduction: Persistent symptoms have been observed in a substantial proportion of survivors of COVID-19 since relatively early in the pandemic. Among these post-acute sequelae of COVID-19 (PASC), respiratory symptoms appear to be the most prevalent.

Methods: We conducted a literature review of peer-reviewed publications in English on the clinical and epidemiological features of respiratory PASC in cohorts of 100 or more patients with a follow-up of four weeks or more after acute infection. Included studies reported the prevalence of persistent respiratory symptoms and/or the results of follow-up pulmonary function tests.

Results: On our review included 14 studies across eight countries …

At nine US hospitals that enrolled children hospitalized with acute respiratory illness (ARI) during 2015-2016 through 2017-2018 influenza seasons, 50% of children with ARI received clinician-initiated testing for influenza and 35% of cases went undiagnosed due to lack of clinician-initiated testing. Marked heterogeneity in testing practice was observed across sites.

The Emergence Of Covid-19 Associated Mucormycosis: A Review Of Cases From 18 Countries, Martin Hoenigl, Danila Seidel, Agostinho Carvalho, Shivaprakash M. Rudramurthy, Amir Arastehfar, Jean-Pierre Gangneux, Nosheen Nasir, Alexandro Bonifaz, Javier Araiza, Nikolai Klimko

Department of Medicine

Reports of COVID-19-associated mucormycosis have been increasing in frequency since early 2021, particularly among patients with uncontrolled diabetes. Patients with diabetes and hyperglycaemia often have an inflammatory state that could be potentiated by the activation of antiviral immunity to SARS-CoV2, which might favour secondary infections. In this Review, we analysed 80 published and unpublished cases of COVID-19-associated mucormycosis. Uncontrolled diabetes, as well as systemic corticosteroid treatment, were present in most patients with COVID-19-associated mucormycosis, and rhino-orbital cerebral mucormycosis was the most frequent disease. Mortality was high at 49%, which was particularly due to patients with pulmonary or disseminated mucormycosis or …

Creation Of A Global Vaccine Risk Index, Tasmiah Nuzhath, Peter J Hotez, Ashish Damania, P Shuling Liu, Brian Colwell

Center for Medical Ethics and Health Policy Staff Publications

The World Health Organization has identified vaccine hesitancy as one of its top ten global health threats for 2019. Efforts are underway to define the factors responsible for reductions in vaccine confidence. However, as global measles cases accelerated beginning in 2018, it became evident that additional factors were promoting measles re-emergence, including war, political and socio-economic collapse, shifting poverty, and vulnerability to weather events and climate change. Accordingly, we propose a Global Vaccine Risk Index (VRI) to consider these variables as a more comprehensive means to identify vulnerable nations where we might expect measles and other vaccine-preventable diseases to emerge …

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant has been hypothesized to decrease the efficacy of COVID-19 vaccines. Factors associated with infections with SARS-CoV-2 after vaccination are unknown. In this observational cohort study, we examined two groups in Harris County, Texas: (1) individuals with positive Nucleic Acid Amplification test between 12/14/2020 and 9/30/2021 and (2) the subset of individuals fully vaccinated in the same time period. Infected individuals were classified as a breakthrough if their infection occurred 14 days after their vaccination had been completed. Among fully vaccinated individuals, demographic and vaccine factors associated with breakthrough infections were …

Immune Response To Sars-Cov-2 Vaccine Among Heart Transplant Recipients: A Systematic Review, Saeed Shoar, Adriana C Carolina Prada-Ruiz, Gabriel Patarroyo-Aponte, Ashok Chaudhary, Mohammad Sadegh Asadi

Faculty, Staff and Student Publications

BACKGROUND: Heart transplant (HTX) recipients are at a significantly higher risk of adverse clinical outcomes, due to chronic immunosuppression and co-existence of other chronic conditions, when contracting the SARS-CoV-2 infection. Although vaccination against SARS-CoV-2 is currently the most promising measure for the prevention of severe Coronavirus Disease 2019 (COVID-19) among solid organ transplant recipients, the extent of immune response and its protective efficacy among patients receiving HTX has not been sufficiently studied.

METHODS: We performed a systematic review of the literature by inquiring PubMed/Medline to identify original studies among HTX recipients, who had received at least one dose of the …

Erythema Multiforme After Third Covid-19 Vaccination (Pfizer-Biontech), Sonali Batta, Austinn C Miller, Susuana Adjei, Laurie A Temiz, Stephen K Tyring

Faculty, Staff and Student Publications

We present a case of erythema multiforme (EM) associated with a third (booster) dose of COVID-19 vaccination in a patient who had no cutaneous reactions to previous doses. To our knowledge, this is the first documented case of vaccine-associated EM occurring after a third/booster vaccination. Furthermore, our case emphasizes the need to remain vigilant for vaccine-associated EM in any patient recently vaccinated, regardless of whether previous vaccinations were administered without cutaneous reactions.

We have shown that membrane-associated guanylate kinase with inverted domain structure-1 (MAGI1), a scaffold protein with six PSD95/DiscLarge/ZO-1 (PDZ) domains, is involved in the regulation of endothelial cell (EC) activation and atherogenesis in mice. In addition to causing acute respiratory disease, influenza A virus (IAV) infection plays an important role in atherogenesis and triggers acute coronary syndromes and fatal myocardial infarction. Therefore, the aim of this study is to investigate the function and regulation of MAGI1 in IAV-induced EC activation. Whereas, EC infection by IAV increases MAGI1 expression, MAGI1 depletion suppresses IAV infection, suggesting that the induction of MAGI1 may …

Consultation/Liaison Psychiatry During Covid-19, Robert Frierson, Steven B Lippmann

The University of Louisville Journal of Respiratory Infections

Consultation/liaison psychiatrists care for people with co-existing medical and psychologic difficulties. The coronavirus pandemic is stressful for patients and their psychiatric caregivers. Patients have lost support systems and harbor fears about exposing family to the virus. COVID-19 sometimes exacerbates previous psychiatric conditions, while diminishing intimacy with physicians. Everyone is oversaturated with COVID-19-related news focusing on rising concerns about the illness and about jobs, school, and housing insecurities.

The psychiatrist maintains a hospital presence despite fear of contracting the disease. Challenges include addressing staff morale, evidencing empathy despite telecommunication devices, and treating anxiety, depression, sleep phobias, post intubation flashbacks, COVID-19-induced cognitive …

BACKGROUND: Typhoid fever is a major public health problem in low-resource settings. Vaccination can help curb the disease and might reduce transmission. We have previously reported an interim analysis of the efficacy of typhoid conjugate vaccine (TCV) in Nepali children. Here we report the final results after 2 years of follow-up.

METHODS: We did a participant-masked and observer-masked individually randomised trial in Lalitpur, Nepal, in which 20 019 children aged 9 months to younger than 16 years were randomly assigned in a 1:1 ratio to receive a single dose of TCV (Typbar TCV, Bharat Biotech International, India) or capsular group …
