Post-Acute Sequelae Of Covid-19 And Polypharmacy: If You Think There’S Too Much Polypharmacy Now, Just Wait, Demetra Antimisiaris

The University of Louisville Journal of Respiratory Infections

The intersection of increased chronic disease burden worldwide with the COVID-19 pandemic was called the “perfect storm”. This article discusses yet another perfect storm: Post COVID-19 (acute and non-acute) syndrome, high chronic disease burdens, advanced age, and polypharmacy. The expected hyper polypharmacy that should result from the added disease and symptom burden due to post COVID-19 syndrome is discussed, as well as the importance of studying the incidence and characteristics to be able to address avoidable medication-related problems.

Baricitinib In The Treatment Of A Critical Patient With Covid-19 Pneumonia: A Case Report, Nishant Patel, Dylan Goldsmith, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

A 72-year-old male presented to the emergency department with a chief complaint of diarrhea after having tested positive for COVID-19 two days prior. He initially had minimal respiratory complaints, but was eventually transferred to the intensive care unit for acute hypoxic respiratory failure. In addition to dexamethasone, remdesivir, and antibiotics, the patient was treated with baricitinib, a Janus kinase inhibitor that was recently granted emergency use authorization by the Food and Drug Administration for treatment of hospitalized patients with COVID-19. He had an extensive and complicated hospital course and had to be placed on mechanical ventilation, ultimately undergoing tracheostomy. After …

Journal of Refugee & Global Health

Refugees are a vulnerable population who experience significant health disparities. They may also be at disproportionately high risk of adverse outcomes due to the COVID-19 pandemic. This paper presents the results of a community needs assessment to investigate the impact of the pandemic on health and welfare in a refugee relocation community in the United States. A multilingual data collection team made up of refugees surveyed 179 participants (128 refugees vs. 51 non-refugees). Only 55.9% of refugee respondents said they would be able to provide enough food for their family this week, compared with 84.0% of non-refugees (p < 0.01), and this difference was even greater for food next week …

The Population Affected By The Syndemic Of Covid-19 And Poverty Is More Likely To Be Hospitalized With Sars-Cov-2 Pneumonia, Julio A. Ramirez, Stephen P. Furmanek, Meredith Cahill, Stephen S. Hanson, Ruth Carrico, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

Background

Lockdown measures to control COVID-19 have exacerbated the poverty epidemic. We hypothesized that the synergistic interaction of COVID-19 and poverty epidemics favors the development of more severe forms of COVID-19 in the population living in poverty. To test this hypothesis, we assessed whether an ecological association exists between the geographic distribution of hospitalized patients with SARS-CoV-2 pneumonia and markers of poverty in the city of Louisville, KY.

Methods

Using the geomasked home addresses of hospitalized patients with SARS-CoV-2 pneumonia in the city of Louisville, a kernel density heatmap was created. Kuldorff’s spatial scan statistic was used to calculate areas …

Particulate Matter Exposure And Community-Acquired Pneumonia Mortality Among Hospitalized Adults With Pneumococcal Pneumonia: Incidence Study (Happi) Participants., Jack Anthony Pfeiffer

Electronic Theses and Dissertations

The role of air pollution as an agent of elevated morbidity and mortality has come under increasingly intense scrutiny in recent years. As the body of literature grows, so too does our understanding of how extensive the harm of such pollutants can be. Particulate matter (PM) particularly harmful due to its small size, ability to travel great distance while airborne, and capacity to infiltrate numerous bodily systems, often to the detriment of those exposed. Besides being associated with increased mortality risk in more heavily exposed populations, PM exposure has also been associated with complications in the respiratory, cardiovascular, and nervous …

Characteristics And Outcomes Of Bacteremic Pneumococcal Pneumonia Of Patients With And Without Hiv Infection In Argentina, Alejandra González

The University of Louisville Journal of Respiratory Infections

Streptococcus pneumoniae is the main causative agent of pneumonia, with a 10 to 25 percent rate of isolation in blood cultures. Controversies exist regarding the prognostic impact of a history of human immunodeficiency virus (HIV) infection on community-acquired pneumonia.

The aim of our work was to analyze and compare the clinical presentation, radiological findings and progression of pneumococcal pneumonia in patients infected with and not infected with HIV. We retrospectively analyzed adult patients with positive blood cultures for Streptococcus pneumoniae and clinical and radiological findings compatible with pneumonia in the period between January 2012 and May 2017. Age, sex, comorbidities, …

Invasive Pneumococcal Serotype 3 Disease Despite Pneumococcal Polysaccharide Vaccine-23, B. Frank Parker Jr, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

Pneumococcal disease has a high global morbidity and mortality. We report a case of a 63-year old female with a history of vaccination with pneumococcal polysaccharide vaccine-23 (PPSV-23) who was transferred to a tertiary care facility with fever and seizures due to an unknown etiology. The diagnosis of invasive pneumococcal disease (IPD) was based the identification of Streptococcus pneumoniae in the blood (culture; serogroup 3) and cerebrospinal fluid (antigen), and the finding of purulence under pressure at craniotomy. The pneumococcal vaccine should provide protection from IPD. The findings reported here display that IPD can overcome immunity proffered by the pneumococcal …

Epigenetic Mechanisms Underlying Hiv-Infection Induced Susceptibility Of Cd4+ T Cells To Enhanced Activation-Induced Fasl Expression And Cell Death., Smita Ghare, Paula M. Chilton, Aakarsha V. Rao, Swati Joshi-Barve, Paula Peyrani, Andrea Reyes-Vega, Craig J. Mcclain, Kendall Bryant, Robert L. Cook, Mathew Freiberg, Shirish Barve

Faculty and Staff Scholarship

Background:

Chronic immune activation and CD4⁺ T cell depletion are significant pathogenic features of HIV infection. Expression of Fas ligand (FasL), a key mediator of activation-induced cell death in T cells, is elevated in people living with HIV-1 infection (PLWH). However, the epigenetic mechanisms underlying the enhanced induction of FasL expression in CD4⁺ T lymphocytes in PLWH are not completely elucidated. Hence, the current work examined the effect of HIV infection on FasL promoter-associated histone modifications and transcriptional regulation in CD4⁺ T lymphocytes in PLWH.

Method:

Flow cytometric analysis was performed to examine the Fas-FasL expression on …

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …
