Investigating Corollaries Between Streptococcus Gallolyticus Subsp. Gallolyticus Virulence And Colorectal Cancer, Tyler G. Myers

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Streptococcus gallolyticus subsp. gallolyticus (Sgg) is a gram-positive, non-beta-hemolytic bacterium that belongs to the Lancefield group D of streptococcal pathogens. For the past several decades, associations between Sgg bacteremia and colorectal cancer (CRC) have been apparent, with gastroenterologists routinely recommending colonoscopies for positive cases of Sgg in either blood or stool samples. However, current research has not wholly established whether Sgg acts as a causative agent of CRC or if pre-existing cancers make the lumen of the colon more hospitable to its colonization. Regardless, Sgg has been implicated in the modulation of host inflammatory pathways and subsequent remodeling …

Background. – BK polyomavirus (BKPyV) is a common opportunistic infection in kidney transplant recipients, typically reactivating in the context of immunosuppression. Although asymptomatic in immunocompetent individuals, reactivation in transplant recipients can cause BKPyV-associated nephropathy (BKPyVAN), a leading cause of graft dysfunction and loss. BKPyV viremia affects approximately 10%–15% of transplant recipients, and once BKPyVAN is established, the risk of graft failure can exceed 50%. The current standard of care involves immunosuppression reduction to restore virus-specific immunity, but this approach increases the risk of acute and chronic rejection. Intravenous immunoglobulin (IVIg), which contains antiviral and immunomodulatory antibodies, has been proposed as …

Research outputs 2022 to 2026

Background and aim: Higher dietary flavonoid intake has been associated with lower risks of mortality and major chronic disease, yet its relationship with psychological well-being (PWB), a key contributor to health and quality of life, remains unclear. This study aimed to investigate bidirectional associations between dietary flavonoid intake and two PWB facets: happiness (positive emotional state) and optimism (generalized expectation of positive outcomes). Specifically, we examined whether (1) overall flavonoid-rich dietary patterns (flavodiet score), (2) intake of specific flavonoid-rich foods, and (3) total flavonoid and subclass intakes were each associated with happiness and optimism over time. Methods: Data were drawn …

Renin-Angiotensin-Aldosterone System In Preeclampsia: Pathophysiological Insights And Links To Vascular Dementia, Robin C. Finch, Jenny Lutshumba, Elizabeth Mirsky, Esther Ndashaala, Kelsey Bullens, Emma Smith

Pediatrics Faculty Publications

Pre-eclampsia, a condition characterized by new-onset hypertension during pregnancy and one or more indices of organ damage, is a major driver of both short and long-term maternal health outcomes. Individuals with a history of pre-eclampsia are at increased risk for cardiovascular, renal, and other chronic diseases. Recent studies have linked pre-eclampsia history with increased risk of dementia later in life, underscoring the importance of new guidelines emphasizing blood pressure control to reduce the risk of cognitive decline. Unfortunately, neither mechanisms underlying causes of pre-eclampsia nor their links with cognitive function are well understood. Vascular contributions to cognitive impairment and dementia …

Rare Presentation Of Omental Tuberculosis With Drug-Induced Jaundice In A Teenage Female: A Case Report, Archana Venkatesan, Krishna Ravi

Advances in Clinical Medical Research and Healthcare Delivery

Omental tuberculosis (TB) is a rare form of abdominal TB, often presenting with nonspecific symptoms that mimic malignancies. We report a case of a 16-year-old female from India who presented with abdominal distension, vomiting, weight loss, and amenorrhea. Imaging revealed an abdominal mass, and a diagnosis of omental TB was confirmed via histopathology. This case highlights the diagnostic challenge posed by such atypical presentations, especially in TB-endemic regions. The patient also developed rifampicin-induced jaundice, which resolved upon drug cessation and supportive care. Anti-TB therapy was cautiously reintroduced at a modified dose. This report underscores the need for high clinical suspicion, …

The aim of this study was to determine whether NAC is associated with changes in functional connectivity, particularly in the basal ganglia, and improvements in Parkinson's symptoms.

METHODS: Forty-four patients with PD were randomized to either weekly intravenous infusions of NAC (50 mg/kg) plus oral doses (500 mg twice per day) for six months plus standard of care, or standard of …

Race And Patient-Physician Communication On Blood Pressure Management: Helping Improve Care, Samar A. Nasser, Ashley Pender, Ayan Ali, Kardie Tobb, Keith C. Ferdinand

Division of Cardiology Faculty Papers

PURPOSE OF REVIEW: To provide an overview of the relationship of race and ethnicity and patient-physician/clinician communication on blood pressure management.

RECENT FINDINGS: The suboptimal interactions experienced by patients from underrepresented racial and ethnic populations may be improved by enriching relationships among clinicians, population health scientists, policymakers, and community members/leaders. Current care communication and policies for managing hypertension appear to be insufficient. Implementing and disseminating effective strategies to efficiently improve the quality of hypertension care and recognize social determinants of health among minoritized populations is intertwined with enhanced communication.

SUMMARY: Approaches such as self-affirmation—encouraging patients to reflect on their strengths …

Tead-Independent Mechanisms Of Yap Function In Cardiomyocyte Cell Cycle Reentry, Bing Xie, Jeffrey Steimle, Vaibhav Deshmukh, Lin Liu, Chang-Ru Tsai, Todd R Heallen, Wyatt Paltzer, Yuka Morikawa, Fansen Meng, Jun Wang, James F Martin

Faculty, Staff and Students Publications

Adult mammalian hearts exhibit limited regenerative capacity because of the restricted renewal of cardiomyocytes. Recent studies reveal that mammalian hearts exhibit transient regenerative potential within a short time frame after birth, suggesting a regulatory mechanism that prevents adult hearts from initiating a regenerative response to cardiac injury. Here, we discovered that an active form of YAP, named YAP6SA, which is not inhibited by the Hippo signaling pathway and does not interact with TEADs, induces cardiomyocyte cell cycle reentry. In addition, YAP6SA interacts with scaffold protein MPDZ to regulate Rho GTPases and promote cell cycle progression in cardiomyocytes (CMs). Importantly, YAP6SA …

Disguised And Dangerous: A Case Of Cervicofacial Actinomycosis Presenting With Hemoptysis, Tharun Shyam, Shamanth M Reddy, Saumya Nanda, Yan Naing Tun, Rohan Pinto, Navjot Somal, Ravi Karan Patti

Journal of Community Hospital Internal Medicine Perspectives

Actinomycosis is a rare, chronic, suppurative bacterial infection caused by Actinomyces spp with an incidence of 0.3 cases per million people annually. The cervicofacial area is the most common site of infection and accounts for approximately 50 percent of all cases. Most cases of cervicofacial actinomycosis are odontogenic in origin.

Hemoptysis in the setting of actinomycosis commonly occurs from pulmonary involvement. Hemoptysis secondary to isolated cervicofacial actinomycosis has seldom been documented in literature. We hereby present a case of cervicofacial actinomycosis presenting with hemoptysis likely secondary to an oro-cervical fistula. We aim to highlight the challenges in diagnosis of this …

Interprofessional Collaboration In Inpatient Rehabilitation For Patient With Thiamine Deficiency-Related Sensorimotor And Cognitive Deficits – Case Report, Christina Thomas, Tahreem Hashmi, Joanne Delgado-Lebron, Rania Massad

Journal of Interprofessional Practice and Collaboration

Purpose: We aim to describe the clinical presentation, interprofessional management, and functional outcomes of a patient with thiamine deficiency. Problem: Thiamine deficiency can result in peripheral polyneuropathy and cognitive deficits that limit function and participation. Despite deficits that warrant interprofessional neurorehabilitation, previous reports focus narrowly on medical management. Case: A 36-year-old female was admitted to inpatient rehabilitation with a diagnosis of Guillain Barre. She underwent evaluation by the interprofessional team that revealed cognitive deficits inconsistent with Guillain Barre. Further medical workup identified a thiamine deficiency. Comprehensive treatment included supplementation managed by the physiatrist; promotion of motor learning and neuroplasticity to …

Alcohol And The Endocrine System: A Critical Review Of Disruptions, Potential Mechanisms, And Health Implications, Patricia E. Molina, Liz Simon

School of Graduate Studies Faculty Publications

The endocrine system coordinates and integrates cellular activity throughout the body by regulating cellular and organ function and maintaining homeostasis. Homeostasis, the dynamic maintenance of internal balance despite changing external or internal conditions, is essential for proper cellular function. The endocrine system achieves this through a complex regulatory network of hormone-mediated signaling among multiple endocrine organs, relying on precisely regulated synthesis and release of hormones and specific hormone-receptor interactions. Endocrine-mediated actions coordinate critical physiological processes, including growth, metabolism, reproduction, stress adaptation, and circadian rhythms throughout the lifespan. Endocrine glands—such as the hypothalamus, pituitary, thyroid, parathyroid glands, pancreas, adrenal glands, and …

Long Acting Beta2-Adrenergic Receptor Agonists Reverse Diabetic Nephropathy And Liver Steatosis In Murine Models Of Diabetes And Are Associated With Protection In Retrospective Human Studies, Brennan Winkler

MUSC Theses and Dissertations

Diabetes Mellitus (DM) affects 13.9% of men and 14.3% of women worldwide, a total of approximately 828 million people. Patients with diabetes are at risk of several complications including diabetic nephropathy (DN) and metabolic-associated steatohepatitis (MASH). These diseases eventually lead to end stage kidney disease (ESKD) and liver failure requiring dialysis and organ transplantation. In addition, diabetes exacerbates disease severity of autosomal dominant polycystic kidney disease (ADPKD), the most common potentially lethal genetic disease to affect humans with a prevalence of 1 in 500-1000. Therefore, a therapeutic approach that can attenuate organ damage and restore function in patients with DM, …
