Developing A Self-Sanitizing Mask To Combat The Spread Of Infectious Disease, Matthew Crawford

Honors Undergraduate Theses

Masks have become an important part of everyday life, protecting both the wearer and individuals nearby from the spread of infectious diseases, most notably severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus that causes coronavirus disease 2019 (COVID-19). However, these masks are easily contaminated, whether through continued use or by the wearer touching the mask fabric with contaminated hands, therefore reducing the efficacy and exposing the user to these contagions. When the mask becomes contaminated, it can be discarded, which produces large amounts of waste that will end up in a landfill, or it can be washed, which is …

Statins And Women, Debra Schulte

Rural Health Professions Projects

Low-density lipoprotein (LDL) elevation is a primary risk factor for atherosclerotic cardiovascular problems such as heart disease and stroke. Heart disease is the leading cause of death in the United States and stroke is the fifth leading. Earlier LDL reduction improves morbidity and mortality. Literature indicates fewer women start statin medications compared to men.

The Promise Of Improved Adherence With Long-Acting Antiretroviral Therapy: What Are The Data?, Kimberly Scarsi, Susan Swindells

Journal Articles: Infectious Diseases

As with other chronic conditions, adherence to daily medications remains a challenge for many individuals living with HIV due to structural, behavioral, and social barriers. Unfortunately, high levels of adherence to antiretroviral therapy are required to maintain virologic suppression. Alternative approaches are being explored to decrease the burden of daily pill administration, including long-acting injectable, oral, and implantable products. Phase 3 data support the efficacy of nanoformulated injectable cabotegravir and rilpivirine for HIV treatment in patients with undetectable viremia, but we have yet to learn how this strategy may benefit those with medication adherence challenges. Despite this, the affected community …

Predictability Of Transcutaneous Bilirubinometry In Late Preterm And Term Infants At Risk For Pathological Hyperbilirubinemia., Ekaterina Dianova Md, J Fogel, R P Verma

Other Specialties

BACKGROUND: The aim was to assess the predictability of transcutaneous bilirubinometry in late preterm and term neonates at risk for pathological hyperbilirubinemia, and to identify the neonatal population in which transcutaneous bilirubin most accurately predicts serum bilirubin level (SB, mg/dl).

METHODS: The correlations between transcutaneous bilirubin (TCB, mg/dl) and SB in different neonatal population subsets; and between ΔTSB (TCB-SB) and relevant neonatal variables and clinical groups were analyzed.

RESULTS: TCB correlated with SB (r = 0.82, p < 0.05) in the cohort (n = 350) and in population subsets (r = 0.81-0.9, p < 0.001). Black infants with gestational age (GA) >35 weeks and chronological age (CA) >3 days recorded strongest correlation (r = 0.9, p < 0.001) followed by Blacks, and non-Black infants with CA >3 days and GA >35 weeks. ΔTSB was …

The Effect Of Age On Neurological Inflammation To Acute Sleep Fragmentation In Mice, Molly Taylor

Mahurin Honors College Capstone Experience/Thesis Projects

Obstructive sleep apnea is identified by recurring events of airway collapse during sleep, intermittent hypoxia, and perturbations in sleep continuity, known as sleep fragmentation. There is evidence to suggest that elderly patients are more at risk of developing obstructive sleep apnea. The purpose of this study was to assess whether age affects neurological inflammatory responses to acute sleep fragmentation. This assessment was made by subjecting young (4-5 months old) and old (10-11 months old) male C57BL/6j mice to automated sleep fragmentation, as well as having mice in both age categories as a control with no sleep fragmentation, for twenty-four hours. …

Antimicrobial Use In Positive Respiratory Viral Panel: Impact Of Procalcitonin Use And Antimicrobial Stewardship, David Beleny

Scholarship in Medicine - All Papers

increasing antibiotic resistant microbes.¹ Blood and sputum cultures are the gold standard for bacterial identification, but they are difficult to obtain and take days to receive back from the lab. Physicians commonly treat patients empirically with antibiotics because there is an increased risk of 30-day mortality in patients with bacterial community-acquired pneumonia (CAP).² Overuse of antibiotics is commonplace in hospitalized patients which is detrimental as it contributes to antibiotic resistance, costs money, wastes resources, and puts patients at risk for unnecessary adverse effects of the medications.³ It was found that 75% of patients presenting with a respiratory …

Kanner, Robert Paine, Ella A. Kazerooni, Fernando J. Martinez, Wanda O'Neal, Stephen I. Rennard, Benjamin M. Smith, Prescott G. Woodruff, Eric A. Hoffman, Ching-Long Lin

Journal Articles: Pulmonary & Critical Care Med

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease and the traditional variables extracted from computed tomography (CT) images may not be sufficient to describe all the topological features of lung tissues in COPD patients. We employed an unsupervised three-dimensional (3D) convolutional autoencoder (CAE)-feature constructor (FC) deep learning network to learn from CT data and derive tissue pattern-clusters jointly. We then applied exploratory factor analysis (EFA) to discover the unobserved latent traits (factors) among pattern-clusters. CT images at total lung capacity (TLC) and residual volume (RV) of 541 former smokers and 59 healthy non-smokers from the cohort of the SubPopulations …

Small Airway Determinants Of Airflow Limitation In Chronic Obstructive Pulmonary Disease, Vasiliy V. Polosukhin, Sergey S. Gutor, Rui-Hong Du, Bradley W. Richmond, Pierre P. Massion, Pingsheng Wu, Justin M. Cates, Kim L. Sandler, Stephen I. Rennard, Timothy S. Blackwell

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Although a variety of pathological changes have been described in small airways of patients with COPD, the critical anatomic features determining airflow limitation remain incompletely characterised.

METHODS: We examined lung tissue specimens from 18 non-smokers without chronic lung disease and 55 former smokers with COPD for pathological features of small airways that could contribute to airflow limitation. Morphometric evaluation was performed for epithelial and subepithelial tissue thickness, collagen and elastin content, luminal mucus and radial alveolar attachments. Immune/inflammatory cells were enumerated in airway walls. Quantitative emphysema scoring was performed on chest CT scans.

RESULTS: Small airways from patients with …

Methods: This prospective survey study was conducted at Miami Valley Hospital, an Urban Level 1 Trauma Center. Trained research assistants obtained verbal consent in private patient treatment rooms. Data were collected from the electronic medical record and from a survey questionnaire. Results: A total of 293 patients consented to participate (95% participation rate). The majority of participants stated that they had signed a consent document (N …

Outcomes In Children And Adolescents Undergoing Cholecystectomies With A High Ejection Fraction, Salony Dighamber, Karen Herzing, Arturo Aranda, Jeffrey C. Pence, Sean Barnett

Scholarship in Medicine - All Papers

Background

Cholecystectomy is commonly performed electively for symptomatic cholelithiasis and biliary hypokinesia with an ejection fraction (EF) less than 35%. Recent literature has shown that cholecystectomy in adults for biliary hyperkinesia (EF>65%) can provide resolution of symptoms (primarily pain) for the majority of patients. We seek to determine whether cholecystectomy is efficacious in the treatment of symptomatic biliary hyperkinesia in the pediatric population.

Method

The charts of over 100 patients aged 7 to 21 in the last 10 years (2008 to 2018) who had cholecystectomies were reviewed to determine ejection fraction, BMI, race, pain with CCK-HIDA, complications, and resolution …

Paediatrics Publications

Stroke in infancy is a rare phenomenon but can lead to significant long-term disability. We present the story of a 6-month-old Old Order Amish infant with underlying Williams syndrome, a rare neurodevelopmental disorder caused by a microdeletion, encompassing the elastin gene that produces abnormalities in elastic fibers of the lungs and vessels. This infant presented with lethargy, irritability, and a new-onset generalized tonic-clonic seizure. Brain magnetic resonance imaging (MRI) was consistent with ischemic stroke in the supratentorial regions. MR angiogram demonstrated bilateral narrowing of the internal carotid arteries with ivy sign, suggestive of Moyamoya. Moyamoya disease/syndrome is a cerebrovascular condition …

Pannexin 1 Binds Β-Catenin To Modulate Melanoma Cell Growth And Metabolism, Samar Sayedyahossein, Kenneth Huang, Zhigang Li, Christopher Zhang, Alexandra M. Kozlov, Danielle Johnston, Daniel Nouri-Nejad, Lina Dagnino, Dean H. Betts, David B. Sacks, Silvia Penuela

Paediatrics Publications

Melanoma is the most aggressive skin malignancy with increasing incidence worldwide. Pannexin1 (PANX1), a member of the pannexin family of channel-forming glycoproteins, regulates cellular processes in melanoma cells including proliferation, migration, and invasion/metastasis. However, the mechanisms responsible for coordinating and regulating PANX1 function remain unclear. Here, we demonstrated a direct interaction between the C-terminal region of PANX1 and the N-terminal portion of β-catenin, a key transcription factor in the Wnt pathway. At the protein level, β-catenin was significantly decreased when PANX1 was either knocked down or inhibited by two PANX1 blockers, Probenecid and Spironolactone. Immunofluorescence imaging showed a disrupted pattern …

Effects Of Maternal Obesity And Gestational Diabetes Mellitus On The Placenta: Current Knowledge And Targets For Therapeutic Interventions, Samantha Bedell, Janine Hutson, Barbra De Vrijer, Genevieve Eastabrook

Obstetrics & Gynaecology Publications

Obesity and gestational diabetes mellitus (GDM) are becoming more common among pregnant women worldwide and are individually associated with a number of placenta-mediated obstetric complications, including preeclampsia, macrosomia, intrauterine growth restriction and stillbirth. The placenta serves several functions throughout pregnancy and is the main exchange site for the transfer of nutrients and gas from mother to fetus. In pregnancies complicated by maternal obesity or GDM, the placenta is exposed to environmental changes, such as increased inflammation and oxidative stress, dyslipidemia, and altered hormone levels. These changes can affect placental development and function and lead to abnormal fetal growth and development …

Examining How Children's Gender Influences Parents’ Perceptions Of The Local Environment And Their Influence On Children's Independent Mobility, Alina Medeiros, Andrew F. Clark, Gina Martin, Jamie A. Seabrook, Jason Gilliland

Paediatrics Publications

Physical inactivity among children is a public health concern. Children's ability to travel independently is associated with increased physical activity and social connectedness. Consequently, it is concerning that children's independent mobility has decreased in recent years. Studies have highlighted that rates of independent mobility vary by gender; this study analyzed how correlates of independent mobility vary between boys (n = 476) and girls (n = 618) attending 32 elementary schools in Southwestern Ontario. Hierarchical logistic regression modeling methods were used. All analyzes were stratified by gender. For boys, age was negatively associated with travel with peers. Having one or more …

Objectives: On January 1, 2020, the Government of Ontario passed a regulation banning vaping advertisements by retailers, apart from specialty shops. A motivation for this ban was to limit youth exposure to vaping advertisements. The primary goal of this research was to evaluate the impact of this ban on the number and density of vaping advertisements surrounding secondary schools. Additionally, we examined whether the number of vaping advertisements varied by school socio-demographic characteristics. Methods: This study used a pre-post design. Audits were conducted December 2019 (pre-ban) and again January to February 2020 (post-ban), to identify vaping advertisements within 800 m …

Sensitivity Of Arterial Spin Labeling For Characterization Of Longitudinal Perfusion Changes In Frontotemporal Dementia And Related Disorders, Tracy Ssali, Udunna C. Anazodo, Lucas Narciso, Linshan Liu, Sarah Jesso, Lauryn Richardson, Matthias Günther, Simon Konstandin, Klaus Eickel, Frank Prato, Elizabeth Finger, Keith St. Lawrence

Paediatrics Publications

Background: Advances in the understanding of the pathophysiology of frontotemporal dementia (FTD) and related disorders, along with the development of novel candidate disease modifying treatments, have stimulated the need for tools to assess the efficacy of new therapies. While perfusion imaging by arterial spin labeling (ASL) is an attractive approach for longitudinal imaging biomarkers of neurodegeneration, sources of variability between sessions including arterial transit times (ATT) and fluctuations in resting perfusion can reduce its sensitivity. Establishing the magnitude of perfusion changes that can be reliably detected is necessary to delineate longitudinal perfusion changes related to disease processes from the effects …

College of Science and Health Full Text Publications

The Open Neuroscience Initiative is a free-to-use textbook

This project began as a means to overcoming the financial burden that face undergraduate neuroscience students when buying textbooks. By compiling and writing a completely free-to-access textbook that covers the foundations of a typical college introduction to neuroscience course, students would have one less obstacle to overcome in their educational career, allowing them to focus their valuable time and attention on learning rather than finances. To make this project a reality, I began with a humble tweet in May 2019 that managed to gain a tiny bit of traction among the neuroscience …

Crippling Rapid Evolution Of Metastasis And Drug Resistance In A549 Non-Small Cell Lung Cancer Cells With The Clinically Relevant Hsp90 Inhibitor Auy922, Nickolas Anthony Bacon

Theses, Dissertations and Capstones

The ability for species to evolve new features in response to changing circumstances in order to survive and propagate is a ubiquitous observation on both the macroscopic and microscopic levels of living systems. It should be no surprise, then, that diseases such as cancer utilize their own forms of adaptation to perpetuate themselves when exposed to external threats. Indeed, concepts drawn from Darwinian evolution are now widely accepted to help explain certain aspects of carcinogenesis and malignant progression, the sum of which have come to be known as the theory of tumor evolution. Since metastasis and drug resistance are features …
