Abo Blood Group Type And Susceptibility To Covid-19 Infection, G. Rafael Fernandez-Botran

The University of Louisville Journal of Respiratory Infections

Since December 2019, the SARS-CoV-2 (COVID-19) pandemic has extended its reach over most of the world, infecting over four million people and causing well over 300,000 deaths so far.[1] A significant percentage of infected patients develop severe symptoms and life-threatening conditions. While COVID-19 infection can affect all ages, available evidence points to older age and pre-existing comorbidities, such as hypertension, diabetes, and coronary heart disease, as important risk factors related to increased mortality rates.[2-4] Moreover, recent reports from China and the U.S. have suggested that susceptibility, and perhaps even mortality, to COVID-19 infection might be influenced by the ABO blood …

Possible Role Of Tetracyclines On Covid-19: Recycling Well-Known Old Drugs From The Shelf, Martin Gnoni, Raul Vasquez-Gararatti, Angel Mena

The University of Louisville Journal of Respiratory Infections

We are in the midst of a pandemic due to the novel coronavirus SARS-CoV-2. Innovative therapies are in the lookup around the world. Recently, chloroquine and hydroxychloroquine in addition to azithromycin were proposed to be used in patients with severe disease even though strong evidence is lacking. We propose the use of tetracyclines in addition to anti-virals early in the curse of the disease in order to prevent the cytokine storm syndrome associated with COVID-19 and prevent ARDS. The proposed mechanisms of tetracyclines are: 1) anti-apoptotic properties; 2) decrease the Myeloperoxidase and ROS releaser from immune cells; 3) decrease neutrophil …

Tobacco Smoke Exposures And Fertility-Related Outcomes Among Females Seeking Fertility Care, And The Interaction With N-Acetyltransferase 2 (Nat2).., T'Shura S. A. Ali

Electronic Theses and Dissertations

Cigarette smoke contains thousands of harmful substances and is one of the leading preventable causes of mortality and morbidity in the United States. Past studies examining tobacco smoke exposures on fecundability and pregnancy outcomes are inconsistent. NAT2 is an important enzyme in the metabolism of xenobiotic substances found within tobacco smoke. This preconception cohort study examines associations between active smoking and secondhand smoke exposure (SHSe) on fecundability and spontaneous abortion (SA), and explores a possible interaction with NAT2 acetylator status. A total of 223 women seeking fertility care were followed for up to 2.3 years. Preconception tobacco smoke exposures were …

Volatile Organic Compound Exposure And Cardiometabolic Syndrome Risk In A Nationally Representative Cohort., Stacey Lane Konkle

Electronic Theses and Dissertations

BACKGROUND: The relative importance of environmental exposures such as volatile organic compounds (VOCs) is one of the paramount public health priorities of our time, yet is presently unstudied. VOCs are ubiquitous in the environment and have been associated with numerous adverse health effects, including a number of cardiovascular and metabolic effects that are components of Cardiometabolic Syndrome (CMS). OBJECTIVES: To examine the relationship between CMS and individual-level exposures to VOCs, measured as urinary metabolites of VOCs (UM-VOCs), in a nationally representative sample. METHODS: Associations between urinary biomarkers of exposure to 19 parent VOCs and CMS were assessed using the National …

Assessing Conduct Disturbance And Fly Ash Exposure In Children., Jillian G. Winn

College of Arts & Sciences Senior Theses

Minimal research has been conducted on fly ash (a byproduct of coal combustion) and health outcomes among exposed communities, and even less has looked at its effect on children’s behavior. This study specifically looks at fly ash exposure and conduct disturbance, using logistic regression to characterize their relationship. Conduct disturbance was gauged by t-scores of 55 or higher on the dimensions of aggression and delinquency of the Child Behavior Checklist. Fly ash exposure was determined by air and surface sampling of the children’s homes. While the odds ratios suggested fly ash exposure increases the likelihood of conduct disturbance, the results …

Louisville Coronavirus Surveillance Program, Julio A. Ramirez, Kenneth E. Palmer, Ruth Carrico, Forest W. Arnold, Donghoon Chung, Leslie A Wolf

The University of Louisville Journal of Respiratory Infections

An important feature of COVID-19, the disease produced by the new coronavirus SARS-CoV-2, is the high number of health care workers (HCWs) that acquire the disease. In an initial report of 138 patients hospitalized with COVID-19 pneumonia in China, 40 patients (29%) were HCWs. One reason why HCWs are at higher risk of acquiring COVID-19 is that some patients with COVID-19 are admitted to the hospital without the classical presentation and are therefore not tested for the disease early during hospitalization. Presently in the US, it is recommended to test for COVID-19 when physicians suspect the disease. This subjective approach …

Developments For The Treatment Of Invasive Infections Due To Multidrug-Resistant Acinetobacter Baumannii, David Laurent, Richard Drew, Dustin Wilson

The University of Louisville Journal of Respiratory Infections

Acinetobacter baumannii is a significant pathogen in healthcare settings (specifically prominent in healthcare- and ventilator-associated pneumonia) due primarily to its virulence and resistance to a wide variety of antimicrobial drug classes, including carbapenems (CRAB). Existing therapies (notably polymyxins, minocycline, tigecycline, amikacin, and sulbactam) often result in suboptimal tissue concentrations, high rates of toxicity, and increasing rates of resistance. Although utilizing combinations of antibiotics (specifically those containing colistin) have been employed, results have been mixed, and control trials are lacking. Eravacycline is a novel tetracycline with an improved pharmacokinetic profile and more potent activity against A. baumannii relative to tigecycline. Cefiderocol …

Association Of Urine Levels Of C-Reactive Protein With Clinical Outcomes In Patients With Pneumonia: A Pilot Study, Subathra Marimuthu, Vidyulata Salunkhe, Stephen P. Furmanek, Leslie A Wolf

The University of Louisville Journal of Respiratory Infections

Finding relevant biomarkers as a potential predictor of severity for patients hospitalized with community acquired pneumonia (CAP), in addition to the clinical scoring system, could advance progress towards more effective patient management. The inflammatory marker, C-reactive protein (CRP), which is elevated in the pathogenesis of many infectious diseases, may be a key biomarker target for CAP. Previous studies have shown that serum CRP may be a useful diagnostic marker for pneumonia in hospitalized patients with acute respiratory symptoms. The main aims of this study were to determine the correlation between serum and urine CRP levels in hospitalized patients with CAP, …

Factors Associated With Full Immunization Coverage Among Children Up To 12 Months, Kakuma Mission Hospital, Turkana County, Kenya, Kevin Lomuria, Naomi Nyakio, Elvis Oyugi, James A. Ransom

Journal of Refugee & Global Health

The 2014 Kenya Demographic Health Survey showed that only 56.7% of children in Turkana County had received all recommended vaccines by 12 months of age, which is 12% below national and 24% below World Health Organization global coverage rates. This study aimed to identify factors that influence full immunization coverage (FIC) by 12 months of age in Kakuma Mission Hospital (KMH), Turkana County, in 2015. Kakuma is the site of a UNHCR refugee camp, established in 1969. Administration of vitamin A by 6 months of age and administration of measles-containing vaccine by 9 months of age were predictive of FIC.
