A Mathematical Model For The Effect Of Social Distancing On The Spread Of Covid-19, Anna Singley, Hannah Callender Highlander

Spora: A Journal of Biomathematics

Social distancing is an effective method of impeding the spread of a novel disease such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but is dependent on public involvement and is susceptible to failure when sectors of the population fail to participate. A standard SIR model is largely incapable of modeling differences in a population due to the broad generalizations it makes such as uniform mixing and homogeneity of hosts, which results in lost detail and accuracy when modeling heterogeneous populations. By further compartmentalizing an SIR model, via the separation of people within susceptible and infected groups, we can more …

Stress And Negative Affect As Mediators In The Association Between Parental Social Support And Lung Function In Adolescents With Asthma, Amber Osorno, Eric Sternlicht, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Zeev N. Kain, Brooke Jenkins

SURF Posters and Papers

Asthma is the leading chronic condition amongst children in the United States as 7.5% of children are diagnosed with asthma. Studies have shown that positive social support is associated with positive asthma management. A strong social support system predicts good management of asthma symptoms; however, current literature has not yet examined how social support impacts lung function as opposed to merely symptom management. Stress and negative affect have been revealed to be associated with worse asthma control, as well as exacerbation of symptoms. Stressful situations, such as the death of a family member, unemployment, and familial tensions lead to worsening …

Cytokine Storm In Covid-19: An Overview, Mechanism, Treatment Strategies, And Stem Cell Therapy Perspective, Nuriza Ulul Azmi, Meidi Utami Puteri, Donny Lukmanto

Pharmaceutical Sciences and Research

Coronavirus disease 2019 (COVID-19) is the disease caused by the highly transmittable novel coronavirus (SARS-CoV-2) infections. The disease was found at the end of December 2019, in Wuhan, China, and quickly spread worldwide with a higher mortality rate compared to the previous coronavirus disease. Cytokine plays an important role in the inflammatory response against coronavirus infection. However, in severely ill patients with COVID-19, an excessive amount of cytokine serum level (cytokine storm) has been associated with the aggravation of coronavirus disease leading to acute respiratory distress syndrome (ARDS). Thus, the management of the cytokine storm could be the key to …

Prospects For Rnai Therapy Of Covid-19, Hasan Uludağ, Kylie Parent, Hamidreza Montazeri Aliabadi, Azita Haddadi

Pharmacy Faculty Articles and Research

COVID-19 caused by the SARS-CoV-2 virus is a fast emerging disease with deadly consequences. The pulmonary system and lungs in particular are most prone to damage caused by the SARS-CoV-2 infection, which leaves a destructive footprint in the lung tissue, making it incapable of conducting its respiratory functions and resulting in severe acute respiratory disease and loss of life. There were no drug treatments or vaccines approved for SARS-CoV-2 at the onset of pandemic, necessitating an urgent need to develop effective therapeutics. To this end, the innate RNA interference (RNAi) mechanism can be employed to develop front line therapies against …

Outlaw Operators: Prevention Failures And The Resurgence Of Black Lung In Central Appalachia, Aysha Bodenhamer

Carsey Publications

In this brief, author Aysha Bodenhamer describes how prevention failures in the coal mining industry have resulted in the resurgence of black lung disease. Caused by the chronic inhalation of coal and silica dust, black lung is progressive, incurable, life-altering, and fatal. Despite it being a preventable disease, black lung is resurgent among coal miners in Kentucky, Virginia, and West Virginia. Fieldwork including in-depth interviews with miners, clinic workers, black lung attorneys, government employees, and lay advocates, and a case-study analysis of two black lung clinics in southwest Virginia inform this analysis. These data reveal that coal operators routinely evade …

The University of Louisville Journal of Respiratory Infections

Introduction: The early automatic diagnosis of the novel coronavirus (COVID-19) disease could be very helpful to reduce its spread around the world. In this study, we revisit the identification of COVID-19 from chest X-ray images using deep learning.

Methods: We collected a relatively large COVID-19 dataset—compared with previous studies—containing 309 real COVID-19 chest X-ray images. We also prepared 2,000 chest X-ray images of pneumonia cases and 1,000 images of healthy controls. Deep transfer learning was used to detect abnormalities in our image dataset. We fine-tuned three, pre-trained convolutional neural network (CNN) models on a training dataset: DenseNet 121, NASNetLarge, and …

Exogenous Lipoid Pneumonia Complicated By Mineral Oil Asperation In A Patient With Chronic Constipation: A Case Report And Review, Hafiz Muhammad Jeelani, Muhammad Mubbashir Sheikh, Belaal Sheikh, Hafiz Mahboob, Anchit Bharat

School of Medicine Faculty Research

Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of …

Convalescent plasma (CP) is one such option that has repeatedly served as an important tool in treatment of various bacterial and viral infections, especially in the setting of no specific antimicrobial or vaccination against an infectious disease. Herein, we review the history of CP, prior …

Chronic Thromboembolic Pulmonary Hypertension, Alyssa Curry

Nursing Student Class Projects (Formerly MSN)

Chronic pulmonary hypertension (CTEPH) is a rare and underdiagnosed complication of unresolved acute pulmonary embolism (PE). A chronic fibrotic thrombus replaces the unresolved emboli in the pulmonary vascular bed causing pre-capillary pulmonary hypertension (Mahmud et al., 2018). Symptoms rang from mild nonspecific such as exercise intolerance and dyspnea. As the disease progresses, symptoms present similarly to right ventricular heart failure (Gopalan et al., 2016). Although the pathophysiology and etiology of CTEPH is still not fully understood, risk factors include increased size of the PE, right ventricular strain, chronic inflammation, and defects in fibrinolysis among others (Fernandes et al., 2016). Treatment …

Phosphodiesterase Isoforms And Camp Compartments In The Development Of New Therapies For Obstructive Pulmonary Diseases, Martina Schmidt, Isabella Cattani-Cavalieri, Francisco J. Nuñez, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

The second messenger molecule 3′5′-cyclic adenosine monophosphate (cAMP) imparts several beneficial effects in lung diseases such as asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). While cAMP is bronchodilatory in asthma and COPD, it also displays anti-fibrotic properties that limit fibrosis. Phosphodiesterases (PDEs) metabolize cAMP and thus regulate cAMP signaling. While some existing therapies inhibit PDEs, there are only broad family specific inhibitors. The understanding of cAMP signaling compartments, some centered around lipid rafts/caveolae, has led to interest in defining how specific PDE isoforms maintain these signaling microdomains. The possible altered expression of PDEs, and thus abnormal …
