BACKGROUND: Diagnosing immune checkpoint inhibitor (ICI)-associated nephritis can be challenging since it is a rare complication of therapy, associated with a spectrum of immune-mediated pathologies, and can present months after ICI therapy discontinuation (i.e., late-onset). ICIs are increasingly administered in combination with other cancer therapies with associated nephrotoxicity, further obfuscating the diagnosis of ICI-associated nephritis. In this report, we describe the first suspected case of late-onset ICI-associated membranous nephropathy (MN) in a patient with metastatic clear cell renal cell carcinoma (RCC) who had discontinued ICI therapy 6 months prior to presentation. Prompt recognition of the suspected late-onset immune-related adverse event …

Xiphodynia is a rare but debilitating condition that can be described as a form of pain on the xiphisternal joint or any related structures that are anchored to the xiphoid process. Although xiphodynia is a musculoskeletal pain in nature, the pain located in the anterior chest can commonly mislead physicians into pursuing other diagnoses such as cardiac diseases. This leads to a prolonged duration of pain before receiving treatment. In the attempt to alleviate pain resulting from this condition, physicians have previously utilized a range of treatment options, including conservative management, injections, or in severe cases, xiphoidectomy. In this review, …

Scope:

Nitrate and nitrite are approved food additives in some animal-based food products. However, nitrate and nitrite in foods are strictly regulated due to health concerns over methaemoglobinaemia and the potential formation of carcinogenic nitrosamines. In contrast, plants (like leafy vegetables) naturally accumulate nitrate ions; a growing body of research reveals beneficial metabolic effects of nitrate via its endogenous conversion to nitric oxide. To refine the association of dietary nitrate and nitrite intake with health outcomes, reliable measures of nitrate and nitrite intake from dietary food records are required. While a vegetable nitrate content database has been developed, there is …

Effects Of Hearing Aid Amplification On The Ability Of Individuals With Hearing Loss To Perceive Spectral Information, Angela Huebert, Marc Brennan Jan 2022

Effects Of Hearing Aid Amplification On The Ability Of Individuals With Hearing Loss To Perceive Spectral Information, Angela Huebert, Marc Brennan

Honors Program: Senior Projects (Public)

Individuals with sensorineural hearing loss often struggle to understand speech even with the use of hearing aids; simply making sounds louder is not enough. Listeners decode various speech sounds with the help of spectral information, but how hearing aid amplification affects individuals’ ability to perceive those cues is not currently well understood. Altering the way hearing aids are programmed to provide amplification can potentially improve the ability of listeners with sensorineural hearing loss to access spectral information. The purpose of this study was to quantify the effects that hearing aid amplification has on the perception of spectral cues. Outcomes could …

Breast cancer (BC) is the most common type of cancer diagnosed in women. Among female cancer deaths, BC is the second leading cause of death worldwide. For estrogen receptor-positive (ER-positive) breast cancers, endocrine therapy is an effective therapeutic approach. However, in many cases, an ER-positive tumor becomes unresponsive to endocrine therapy, and tumor regrowth occurs after treatment. While some genetic mutations contribute to resistance in some patients, the underlying causes of resistance to endocrine therapy are mostly undetermined. In this study, we utilized a recently developed statistical approach to investigate the dynamic behavior of gene expression during the development of …

Amelogenesis imperfecta is a congenital disorder within a heterogeneous group of conditions characterized by enamel hypoplasia. Patients suffer from early tooth loss, social embarrassment, eating difficulties, and pain due to an abnormally thin, soft, fragile, and discolored enamel with poor aesthetics and functionality. The etiology of amelogenesis imperfecta is complicated by genetic interactions. To identify mouse amelogenesis imperfecta-related genes (mAIGenes) and their respective phenotypes, we conducted a systematic literature review and database search and found and curated 70 mAIGenes across all of the databases. Our pathway enrichment analysis indicated that these genes were enriched in tooth development-associated pathways, forming four …

Allergic asthma is a chronic inflammatory respiratory disease associated with eosinophilic infiltration, increased mucus production, airway hyperresponsiveness, and airway remodeling. Epidemiologic data reveal that the prevalence of allergic sensitization and associated diseases has increased in the twentieth century. This has been hypothesized to be partly due to reduced contact with microbial organisms (the hygiene hypothesis) in industrialized society. Airway epithelial cells, once considered a static physical barrier between the body and the external world, are now widely recognized as immunologically active cells that can initiate, maintain, and restrain inflammatory responses, such as those that mediate allergic disease. Airway epithelial cells …
