Assessing Cognitive Health Outcomes In Anca-Associated Vasculitis Patients, Ruo Yan Chen 2022 Western University

Assessing Cognitive Health Outcomes In Anca-Associated Vasculitis Patients, Ruo Yan Chen

Undergraduate Student Research Internships Conference

Anti-neutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare and life-threatening autoimmune disease with severe complications. Central nervous system (CNS) involvement is thought to be rare, however, the prevalence of neuropsychiatric complications have been reported in 30-60% of AAV cases. Studies looking at the cognitive health outcomes of AAV patients with CNS involvement have noted cognitive impairment as a significant contributor to reduced quality of life with unique challenges in care and treatment. The data collected from this primary output could be combined with global assessments of cognitive function as well as the application of advanced imaging tools to study …

Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, and antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy to manage pandemic. Although none of the currently approved vaccines are live-attenuated, several reports of disease flares, waning protection, and acute-onset syndromes have emerged as short-term adverse events after vaccination. Hence, scientific literature falls short when discussing potential long-term effects in vulnerable cohorts. The COVAD-2 survey follows on from the baseline COVAD-1 survey with the aim to collect patient-reported data on the long-term …

Recent studies have shown that immune infiltrates in the tumor microenvironment play a role in response to therapy, with some suggesting that patients with immunogenic tumors may receive increased benefit from chemotherapies. We evaluated this hypothesis in early breast cancer by testing the interaction between immune biomarkers and chemotherapy using materials from DBCG77B, a phase III clinical trial where high-risk premenopausal women were randomized to receive chemotherapy or no chemotherapy. Tissue microarrays were evaluated for tumor-infiltrating lymphocytes (TILs) assessed morphologically on hematoxylin and eosin-stained slides, and by immunohistochemistry for CD8, FOXP3, LAG-3, PD-1 and PD-L1. Following REMARK reporting guidelines, data …

We have seen four decades of human struggle to cure or eradicate HIV infection since the first clinical detection of HIV infection. Various developed drugs such as nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors, integrase inhibitors, microbicides, and others have known restrictions, such as side effects and resistance development when used alone, and hidden reservoir of the virus, which have opened the gates for the involvement of nanomedicine associated systems, particularly for latent sites of HIV infection. The nanotechnological vehicles, such as liposomes, dendrimers, metal nanoparticles, polymeric nanocapsules/particles, surfactants, and targeted vehicles have become part …

Myasthenia Gravis, Rebecca Wheeler 2022 Otterbein University

Myasthenia Gravis, Rebecca Wheeler

Nursing Student Class Projects (Formerly MSN)

Myasthenia gravis (MG), a neuromuscular and autoimmune disorder, is not completely understood by clinicians and scientists. The primary cause is thought to be anti-Acetylcholine receptor antibodies that attack the neuromuscular junction, causing destruction of post-synaptic junctional folds and blockade of the receptor. This causes frequent weakness and fatigability of voluntary muscles, making activities of daily living difficult for those living with MG. Although it is not an incredibly prevalent disease, the incidence is increasing in the United States due to better testing and diagnosis. Treatments are available, including cholinesterase inhibitors that raise the concentration of Acetylcholine at the neuromuscular junction …

Department of Paediatrics and Child Health

Enteric fever infections remain a significant public health issue, with up to 20 million infections per year. Increasing rates of antibiotic resistant strains have rendered many first-line antibiotics potentially ineffective. Genotype 4.3.1 (H58) is the main circulating lineage of S. Typhi in many South Asian countries and is associated with high levels of antibiotic resistance. The emergence and spread of extensively drug resistant (XDR) typhoid strains has increased the need for a rapid molecular test to identify and track these high-risk lineages for surveillance and vaccine prioritisation. Current methods require samples to be cultured for several days, followed by DNA …

Pharmacy Faculty Articles and Research

The activity of nucleoside and nucleotide analogs as antiviral agents requires phosphorylation by endogenous enzymes. Phosphate-substituted analogs have low bioavailability due to the presence of ionizable negatively-charged groups. To circumvent these limitations, several prodrug approaches have been proposed. Herein, we hypothesized that the conjugation or combination of the lipophilic amide bond with nucleotide-based tenofovir (TFV) (1) could improve the anti-HIV activity. During the current study, the hydroxyl group of phosphonates in TFV was conjugated with the amino group of L-alanine, L-leucine, L-valine, and glycine amino acids and other long fatty ester hydrocarbon chains to synthesize 43 derivatives. Several …
