Lung-Delivered Il-10 Therapy Elicits Beneficial Effects Via Immune Modulation In Organic Dust Exposure-Induced Lung Inflammation, Aaron D. Schwab, Todd A. Wyatt, Amy J. Nelson, Angela Gleason, Rohit Gaurav, Debra J. Romberger, Jill A. Poole

Journal Articles: Pulmonary & Critical Care Med

Efficacious therapeutic options capable of resolving inflammatory lung disease associated with environmental and occupational exposures are lacking. This study sought to determine the preclinical therapeutic potential of lung-delivered recombinant interleukin (IL)-10 therapy following acute organic dust exposure in mice. Here, C57BL/6J mice were intratracheally instilled with swine confinement organic dust extract (ODE) (12.5%, 25%, 50% concentrations) with IL-10 (1 μg) treatment or vehicle control intratracheally-administered three times: 5 hr post-exposure and then daily for 2 days. The results showed that IL-10 treatment reduced ODE (25%)-induced weight loss by 66% and 46% at Day 1 and Day 2 post-exposure, respectively. IL-10 …

Microbial Profile And Antimicrobial Resistance Patterns Of Surgical Intra-Abdominal Infections At A Tertiary Hospital In Tanzania A Retrospective Cross-Sectional Study, Abduel Julius Kitua

Master of Surgery

v>

Among infections of surgical importance, intra-abdominal infections prevail among the most common in surgical patients with considerable morbidity and mortality. The ever-rising microbial resistance to commonly available antibiotics and geographical variations in microbial profile and resistance patterns poses a challenge to the management of these surgical infections of abdominal origin. The aim of this study was to evaluate microbiological characteristics and antibiotic susceptibility of isolates from intra-abdominal infections at a tertiary hospital in Tanzania and how these influence early treatment outcomes.

Impacts Of Climate Change On Vector-Borne Disease Burden In The United States: Exploring The Epidemiological Evidence, Leah V. Loetman

Honors Theses

Climate change models predict shifts in vector-borne diseases (VBDs) around the world, including in the United States. However, to my knowledge there has yet to be a comprehensive descriptive epidemiological study examining prevalence, geographic distribution, and trends for all tick- and mosquito-borne diseases in the United States. I compiled data from the U.S. Centers for Disease Control (CDC), which publishes yearly case numbers for 17 vector-borne diseases. However, these publications depend on a scattered framework of state regulations regarding disease reporting. I compiled data from the CDC to determine the current geographic distribution, prevalence, and trends of tick- and mosquito-borne …

Reiq-Mediated Alarmone Signalling Regulates Growth, Stress-Induced Biofilm Formation And Spore Accumulation In Clostridioides Difficile, Areej Malik, Adenrele Oludiran, Asia Poudel, Orlando Berumen Alvarez, Charles Woodward, Erin B. Purcell

Chemistry & Biochemistry Faculty Publications

The bacterial stringent response (SR) is a conserved transcriptional reprogramming pathway mediated by the nucleotide signalling alarmones, (pp)pGpp. The SR has been implicated in antibiotic survival in Clostridioides difficile, a biofilm- and spore-forming pathogen that causes resilient, highly recurrent C. difficile infections. The role of the SR in other processes and the effectors by which it regulates C. difficile physiology are unknown. C. difficile RelQ is a clostridial alarmone synthetase. Deletion of relQ dysregulates C. difficile growth in unstressed conditions, affects susceptibility to antibiotic and oxidative stressors and drastically reduces biofilm formation. While wild-type C. difficile displays increased biofilm …

High Prevalence Of Trypanosoma Cruzi Infection In Raccoons (Procyon Lotor) And Associated Risk To Humans In Central Illinois, Esther Onuselogu

Masters Theses

Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, remains a neglected tropical disease and a growing health threat in the United States. Raccoons (Procyon lotor) often coexist with humans in urban and suburban areas and serve as reservoir hosts for T. cruzi. While T. cruzi is rare in humans and domestic animals in the U.S., it is common in wildlife species, particularly raccoons and Virginia opossums (Didelphis virginiana). This study aimed to assess the prevalence of T. cruzi infection in the raccoon population of Central Illinois and evaluate the risk of transmission to humans. …

Unveiling The Complex World Of Extracellular Vesicles: Novel Characterization Techniques And Manufacturing Considerations, James J Lai, John J Hill, Casey Y Huang, Gino C Lee, Karol W Mai, Maggie Y Shen, Simon K Wang

Faculty, Staff and Student Publications

Extracellular vesicles (EVs) function as potent mediators of intercellular communication for many in vivo processes, contributing to both health and disease related conditions. Given their biological origins and diverse functionality from correspondingly unique "cargo" compositions, both endogenous and modified EVs are garnering attention as promising therapeutic modalities and vehicles for targeted therapeutic delivery applications. Their diversity in composition, however, has revealed a significant need for more comprehensive analytical-based characterization methods, and manufacturing processes that are consistent and scalable. In this review, we explore the dynamic landscape of EV research and development efforts, ranging from novel isolation approaches, to their analytical …

Improving Clostridium Difficile Detection At Medical City Arlington: A Quality Improvement Project, Bremmy Alsbrooks, Nur-Alhuda Shahub, Shabaz Mallick, Jesse Brown, Afsha Rais, Afsha Rais

North Texas GME Research Forum 2024

INTRODUCTION: Hospital acquired Clostridium difficile infection are one of the costliest hospital acquired infections. Over the past year, there were 19 C diff cases. Reasons for this uptick in cases from previous years could be waiting too long for collection (where a patient has C diff on admission, but does not receive testing until several days later), antibiotics, environmental (for example, using the same toilet brush to clean bathrooms on the floor as well as the bathroom in a C diff patient's room, cleaning high touch areas less than two times during the day, etc.), or staff education. From our …

Optimizing Ventilator-Associated Pneumonia Prevention And Education: In Adult Icu Settings, Danielle Gonzalez

Nursing | Senior Theses

Background: Ventilator associated pneumonia (VAP) in adult intensive care patient units (ICU) is one of the most common and deadly nosocomial infections today. Studies have identified a gap in intensive care nurse ventilator education and compliance with hospital protocols. Overall increasing the rates of VAP and morbidity. Hospitals worldwide have shown a decrease in VAP rates after inheriting "VAP-bundles''. This includes nurse specific interventions and assessments as a preventative measure. However, studies failed to demonstrate which bundle interventions directly correspond to the prevention of VAP. Purpose: Address all components of education, a nurse’s ability to properly identify and understand the …

Distribution Of Tick Species On Free-Ranging Ungulates In Northern New England, Karisa Graham

Honors Theses and Capstones

In Northern New England, ungulates are often parasitized by ticks, which is one of the leading causes for the decline in population. Ungulates are a good host for ticks, specifically deer ticks and winter ticks, and these ticks cause many tick-borne diseases in humans as well. The purpose of this study was to assess passive sampling from harvested animals as a means of tick surveillance in Vermont and New Hampshire. Ticks were collected from deer and moose and mapped throughout the two states by ArcGIS to visualize the trends in distribution. Relative abundance was greater in southeastern Vermont, with no …

Tissue-Specific Localization Of Tick-Borne Pathogens In Ticks Collected From Camels In Kenya: Insights Into Vector Competence, Rua Khogali, Armanda Bastos, Joel L. Bargul, Dennis Getange, James Kabii, Daniel Masiga, Jandouwe Villinger

All Peer-Reviewed Publications

Background: Tick-borne pathogen (TBP) surveillance studies often use whole-tick homogenates when inferring tick-pathogen associations. However, localized TBP infections within tick tissues (saliva, hemolymph, salivary glands, and midgut) can inform pathogen transmission mechanisms and are key to disentangling pathogen detection from vector competence. Methods: We screened 278 camel blood samples and 504 tick tissue samples derived from 126 camel ticks sampled in two Kenyan counties (Laikipia and Marsabit) for Anaplasma, Ehrlichia, Coxiella, Rickettsia, Theileria, and Babesia by PCR-HRM analysis. Results: Candidatus Anaplasma camelii infections were common in camels (91%), but absent in all samples from Rhipicephalus pulchellus, Amblyomma gemma, Hyalomma dromedarii, …

Gut Dysbiosis Correlates With Covid-19 Severity, Ednita Escobar

CMC Senior Theses

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) impacts not only respiratory but also gut and oral microbiomes, influencing the manifestations of COVID-19. Each person’s unique microbiome consists of microorganisms such as bacteria, fungi, and viruses, some of which are symbiotic and others potentially harmful. Alterations in the gut microbiome, specifically, can affect the severity and symptoms of COVID-19. A review of studies indicate a pattern of gut dysbiosis in COVID-19 patients characterized by a decrease in beneficial microbiota and/or an increase in opportunistic pathogens. This gut imbalance correlates with disease severity, suggesting that the gut microbiome plays a significant role …
