Preventive Effects Of Quercetin On The Leaky Gut By Suppression Of Il-1beta-Induced Transcription Factors Involved In An Inflammatory Pathway In Colonic Epithelial Cells, Wannaporn Chayalak, Sumpun Thammacharoen, Chatsri Deachapunya, Sutthasinee Poonyachoti

The Thai Journal of Veterinary Medicine

Flavonol quercetin (Q), found in vegetables and fruits, demonstrates the most potent anti-inflammatory effect. The preventive effect and cellular mechanisms of Q (Q1, Q10, and Q100 µM) on IL-1β induced leaky gut via the signaling molecules of inflammatory pathway, NF-κB p65-iκB/or p38/ERK1/2/MLCK/phospho(p)-MLC were investigated in Caco-2 cells. The cytotoxic effect of Q was initially determined by MTT assay. Transepithelial electrical resistance (TER) and apical-to-basolateral fluorescein isothiocyanate-labeled dextran (FD-4) flux were used to determine paracellular permeability. The protein expression of signaling molecules was examined by Western blot analysis, and their target MLCK mRNA expression was determined using real-time PCR. All Q …

Determinants Of Vaccine Hesitancy Among Parents And Caregivers, Priya Srivastava

Rowan-Virtua Research Day

•Vaccination efforts in the United States and globally are one of the largest contributors to pediatric preventative health

•Routine immunizations in the U.S for children ≤ 10 years old cover 14 vaccine-preventable diseases. As a result, an estimated 732,000 deaths, 21 million hospitalizations, and 322 diagnosed cases of diseases have been prevented between 1993 and 2013.

•Vaccines remain a point of contention with pediatricians and their patients' caregivers

•Many parents maintain hesitancy to give vaccines; to a number of reasons. Perceived risk and fear of side effects from vaccines more than the disease itself, can cause out-of-proportion concern

•Misinformation spread …

A Novel Approach To Hiv Testing: Group Harm Reduction And Testing For High Risk Women In Nj, Gabrianna A. Andrews

Rowan-Virtua Research Day

Outreach programs have been implemented aimed at providing healthcare to minority populations and those considered high-risk for acquiring HIV.

Data was collected from 6/2/2023 to 4/19/2024 by surveying participants at the end of the interaction. 87.5% of participants rated their care at the mobile clinic as ‘Excellent’, 8% as ‘Very Good’, and 4.5% as ‘Good’. 95.6% of participants ranked Group Harm Reduction Counseling as ‘Definitely’ helpful. 84.4% of participants did not find that …

Evaluation Of The Efficacy Of Novel Drugs And Combinations Against Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Isolates, Keertana Jonnalagadda, Rachel Carr, Valerie Carabetta

Rowan-Virtua Research Day

Acinetobacter baumannii, a Gram-negative, nosocomial, opportunistic pathogen is commonly infectious in immunocompromised patients. More specifically patients develop healthcare-associated infections (HAI) spanning beyond sepsis, pneumonia, meningitis, and urinary tract infections. Due to its rapid ability to acquire antibiotic resistance, it has raised the necessity to discern a novel therapeutic treatment that can be effectively used against the multidrug resistant (MDR) A. baumannii. Cooper University Hospital (CUH) faced an increased case load of patients that were infected with MDR A. baumannii. The patient isolates obtained from CUH were highly resistant to the 22 standard-of-care antibiotics. With the recent introduction …

Ischemic Colitis In A Middle-Aged Man With Covid-19: Case Report And Review Of Literature, Lara Appiah, Subhasis Misra, Stephen Jones

HCA Healthcare Journal of Medicine

Introduction

Coronavirus disease 2019 (COVID-19) was a pandemic that began in 2019 and continues to have morbid and deadly consequences throughout the world. During the beginning of the pandemic, many considered older adults and immunocompromised younger adults to be the only populations at risk for the severe consequences of COVID-19. Throughout the pandemic, this was proven wrong with several case reports and studies showing that relatively younger adults can also suffer serious consequences from this perplexing virus.

Modeling An Infection Outbreak With Quarantine: The Sibkr Model, Mikenna Dew, Amanda Langosch, Theadora Baker-Wallerstein

Rose-Hulman Undergraduate Mathematics Journal

Influenza is a respiratory infection that places a substantial burden in the world population each year. In this project, we study and interpret a data set from a flu outbreak in a British boarding school in 1978 with mathematical modeling. First, we propose a generalization of the SIR model based on the quarantine measure in place and establish the long-time behavior of the model. By analyzing the model mathematically, we determine the analytic formulas of the basic reproduction number, the long-time limit of solutions, and the maximum number of infection population. Moreover, we estimate the parameters of the model based …

Sub-Saharan Africa’S Handling Of Covid-19 Pandemic: Rwanda Versus Tanzania, Luke D. Baumel

Non-Thermal Plasma Reduces Hsv-1 Infection Of And Replication In Hacat Keratinocytes In Vitro, Julia Sutter, Jascha Brettschneider, Brian Wigdahl, Peter Bruggeman, Fred Krebs, Vandana Miller

Kimmel Cancer Center Faculty Papers

Herpes simplex virus type 1 (HSV-1) is a lifelong pathogen characterized by asymptomatic latent infection in the trigeminal ganglia (TG), with periodic outbreaks of cold sores caused by virus reactivation in the TG and subsequent replication in the oral mucosa. While antiviral therapies can provide relief from cold sores, they are unable to eliminate HSV-1. We provide experimental results that highlight non-thermal plasma (NTP) as a new alternative therapy for HSV-1 infection that would resolve cold sores faster and reduce the establishment of latent infection in the TG. Additionally, this study is the first to explore the use of NTP …

Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar

Research Symposium

Background: Common cutaneous warts, referred to in medicine as verrucae vulgaris, are proliferative lesions caused by human papillomavirus. These lesions are mostly benign and usually resolve without incident, except in the case of the patient mentioned in this report. Our patient developed a solitary keratoacanthoma, currently accepted as a clinical variant of squamous cell carcinoma, as a result of several risk factors and traumatic exposure. The current literature does not have an established association of HPV with solitary keratoacanthomas. This case report explores the presentation and pathogenesis of solitary keratoacanthomas within the setting of HPV.

Streptococcus Canis Native Aortic Valve Endocarditis Linked To Cat Exposure: A Case Report And Review, Michael S. Wang, Maria Huaringa, Lauren Feld, Ken Ochiai, Tiffany Whelan, Nicholas M. Frazier

Journal of Community Hospital Internal Medicine Perspectives

Streptococcus canis is an uncommon human pathogen, but documented infections have been mostly associated with exposure to dogs. There are only five documented cases of endocarditis secondary to streptococcus canis, with all cases except one documenting exposure to a canine. We present a 74-year-old male with a history of Type 2 diabetes mellitus, CKD 3, moderate aortic stenosis and remote exposure to agent orange, who was found to have Streptococcus canis native valve endocarditis without exposure to a dog. To the best of our knowledge this case is the first case of endocarditis linked to feline exposure.

Advances in Clinical Medical Research and Healthcare Delivery

Kaposi Sarcoma (KS) is a multifocal systemic disease first identified in 1872. It most commonly involves the skin, mucous membranes, lymph nodes, and gastrointestinal tract. There are four clinically distinct subtypes of KS that have been identified: Chronic or classic KS, African endemic KS, KS due to iatrogenic immunosuppression, and AIDS-related epidemic KS. The human herpesvirus 8 (HHV-8) has been implicated in all subtypes of KS. We present a unique case of KS in a 79-year-old male with a widespread distribution of skin lesions on his palms, soles, chest, and back. This case report highlights a novel presentation of classical …

Targeting Cyp51 In The Treatment Of Acanthamoeba Keratitis, Ashkan Hassani, Vineet Sadarangani, Brad Haubrich

Annual Research Symposium

Acanthamoeba castellanii causes a rare but serious ocular infection called Acanthamoeba keratitis. Risk factors for infection include contact with contaminated water and poor hygiene of contact lenses. The first-line treatment is comprised of a months-long schedule of antibiotics. However, in cases where pharmacological interventions fail to address the infection, surgery may be necessary, with the continued risk of potential vision loss. Consequently, new treatments are needed, whether new pharmacological agents or new combination therapies with current agents. As an aerobic parasite, Acanthamoeba synthesizes ergosterol as a cell membrane insert, and ergosterol biosynthesis inhibitors (EBIs), common in antifungal pharmaceuticals, could potentially …

Microsporidiosis: Reviewing Clinical Presentation And Treatment Strategies, Julienne Zhou, Belinda Liu, Megan Dearmond, David Banach, Brad Haubrich

Annual Research Symposium

Microsporidiosis is an opportunistic infection caused by obligate intracellular pathogens within the taxon Microsporidia. Infection is zoonotic and has been associated with patients experiencing immunodeficiency, though incidence is increasing among other populations. Most commonly, the disease is gastrointestinal, typically by Enterocytozoon bieneusi and less commonly by Encephalitozoon intestinalis. Symptoms present with diarrhea and vomiting, and severe cases can lead to wasting and mortality. While the incorporation of anti-retroviral therapy for HIV patients has significantly decreased mortality in a subset of the vulnerable populations, treatment for microsporidiosis is still not standardized or well explored. Resistance to first-line treatment albendazole is increasing, …
