BACKGROUND: Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.

METHODS: We utilized retrospective, real-world data from the OneFlorida + Clinical Research Consortium. Our study focused on two primary endpoints: ischemic and bleeding events, with prediction windows of 1, 2, 3, 6, and 12 months post-DES implantation. Our approach first …

Heart failure (HF) is a chronic, debilitating condition associated with significant morbidity, mortality, and socioeconomic burden. Patients with end-stage HF (ESHF) who are not a candidate for advanced therapies will continue to progress despite standard medical therapy. Thus, the focus of care shifts from prolonging life to controlling symptoms and improving quality of life through palliative care (PC). Because the condition and prognosis of HF patients evolve and can rapidly deteriorate, it is imperative to begin the discussion on end-of-life (EOL) issues early during HF management. These include the completion of an advance directive, do-not-resuscitate orders, and policies on device …

Review Of Current Dual-Antiplatelet And Triple Therapy Prescribing Practices At Providence Medical Group, Gina Kim, Christine Doran, Lauren Powell

Books, Presentations, Posters, Etc.

Abstract: Approximately 10% of patients with recent percutaneous intervention (PCI) have concomitant atrial fibrillation (AF) and others may have concomitant venous thromboembolism (VTE). This makes choosing the optimal antithrombotic regimen challenging. The ACC published a 2020 decision pathway to guide safe and evidence-based use of antiplatelet and anticoagulant combinations for certain patients. These situations include patients with prior AF on anticoagulation and the need for PCI, patients with new-onset AF requiring anticoagulation in a patient already on antiplatelet therapy for coronary artery disease (CAD), patients with prior VTE on anticoagulation and the need for PCI, and patients with new or …

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 …

A Retrospective Study On The Effect Of Raas Pathway Inhibitors At Decreasing The Risk Of Acute Coronary Syndrome In Hypertensive Patients With Rheumatoid Arthritis As Compared To Other Antihypertensives, Yousuf Sherwani, Asad Risvi, Senthil Thambidorai

North Texas GME Research Forum 2024

Rheumatoid arthritis (RA) is a chronic multi-system inflammatory disease of which is characterized by articular and extra-articular involvement. Patients with RA have a higher risk of mortality when compared with the general population, which is due predominantly to increased cardiovascular disease. Due to the higher incidence of CVD and MI in RA patients it has been postulated that enhanced systemic inflammation plays an important role in the pathogenesis of CVD in RA patients. Previous studies have shown that ant inflammatory medication such as systemic steroids and immune blockers have been shown to decrease the risk of MI in patients with …

Effects Of Menopause On Coronary Artery Disease, Angelica Gonzales

Nursing | Senior Theses

Menopausal women, 40 to 60 years old, have an increased risk of developing coronary artery disease (CAD) when they experience hormonal changes. Which then can lead to unwanted cardiac events. Within the literature review of this paper, it was found that there are factors of menopause that may further increase the risk of coronary artery disease in menopausal women. Such factors include whether a woman underwent surgical or natural menopause and the timing when menopause began. Additionally, within the review, hormone replacement therapy (HRT) was explored to determine whether the possible intervention can decrease the progression and risk of developing …

Astrocytic Mitochondrial Transfer To Brain Endothelial Cells And Pericytes In Vivo Increases With Aging, Gopal V. Velmurugan, Hemendra J. Vekaria, Samir P. Patel, Patrick G. Sullivan, W. Brad Hubbard

Neurology Faculty Publications

Intercellular mitochondrial transfer (IMT) is an intriguing biological phenomenon where mitochondria are transferred between different cells and notably, cell types. IMT is physiological, occurring in normal conditions, but also is utilized to deliver healthy mitochondria to cells in distress. Transferred mitochondria can be integrated to improve cellular metabolism, and mitochondrial function. Research on the mitochondrial transfer axis between astrocytes and brain capillaries in vivo is limited by the cellular heterogeneity of the neurovascular unit. To this end, we developed an inducible mouse model that expresses mitochondrial Dendra2 only in astrocytes and then isolated brain capillaries to remove all intact astrocytes. …

Using Digital Pathology To Analyze The Murine Cerebrovasculature, Dana M. Niedowicz, Jenna L. Gollihue, Erica M. Weekman, Panhavuth Phe, Donna M. Wilcock, Christopher M. Norris, Peter T. Nelson

Neurology Faculty Publications

Research on the cerebrovasculature may provide insights into brain health and disease. Immunohistochemical staining is one way to visualize blood vessels, and digital pathology has the potential to revolutionize the measurement of blood vessel parameters. These tools provide opportunities for translational mouse model research. However, mouse brain tissue presents a formidable set of technical challenges, including potentially high background staining and crossreactivity of endogenous IgG. Formalin-fixed paraffin-embedded (FFPE) and fixed frozen sections, both of which are widely used, may require different methods. In this study, we optimized blood vessel staining in mouse brain tissue, testing both FFPE and frozen fixed …

Home Blood Pressure Monitoring Bundle For Hypertension Outcomes In Adult Patients Receiving Care In Public Health Clinics, Christine Jennifer Victorian

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Background: Hypertension (HTN) that is not adequately controlled leads to cardiovascular disease, stroke, and heart disease. It affects 116 million adults (47%) in the United States (U.S.). The HTN compliance rate in a South Texas public health clinic was 64%, below the national benchmark of 76%. Home blood pressure monitoring (HBPM) was recommended in a joint statement by the American Heart Association (AHA) and the American Medical Association (AMA). Literature evidence revealed that the HBPM bundle increased BP control (< 140/90 mmHg) compliance.

Methods: A quality improvement (QI) bundle was initiated to address the low HTN compliance rate from a quality management perspective. …

Autonomic Modulation Of Cardiac Function In Hypertrophic Cardiomyopathy, Jenna Rose Disser

Dissertations, Master's Theses and Master's Reports

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disorder. HCM is characterized by cardiac hypertrophy, fibrosis, and an increased risk of fatal arrhythmias and sudden cardiac death. Previous studies in humans with HCM have demonstrated increased cardiac norepinephrine spillover and reduced beta-1 receptor (β1R) expression in the left ventricle (LV). We have previously demonstrated that cardiac sympathetic tone is elevated in an alpha-tropomyosin mutant mouse model of HCM. We hypothesized that HCM mice would demonstrate reduced β1R expression in the LV and attenuated heart rate (HR) and dP/dt max responses to ramped infusion of the β1R agonist, dobutamine. …

Background: Previous research has shown that the Serum Amyloid A (SAA) protein family is intricately involved in inflammatory signaling and various disease pathologies. We have previously demonstrated that SAA is associated with increased colitis disease severity and the promotion of tumorigenesis. However, the specific role of SAA proteins in breast cancer pathology remains unclear. Therefore, we investigated the role of systemic SAA1 and SAA2 (SAA1/2) in a triple-negative breast cancer mouse model.

Methods: Syngeneic breast tumors were established in wild-type mice, and mice lacking the SAA1/2 (SAADKO). Subsequently, tumor volume was monitored, species survival determined, the inflammatory profiles of mice …

Background and aims: Obesity and type 2 diabetes are significant risk factors for atherosclerotic cardiovascular disease (CVD) worldwide, but the underlying pathophysiological links are poorly understood. Neurotensin (NT), a 13-amino-acid hormone peptide, facilitates intestinal fat absorption and contributes to obesity in mice fed a high-fat diet. Elevated levels of pro-NT (a stable NT precursor produced in equimolar amounts relative to NT) are associated with obesity, type 2 diabetes, and CVD in humans. Whether NT is a causative factor in CVD is unknown.

Methods: Nt+/+ and Nt–/– mice were either injected with adeno-associated virus encoding PCSK9 mutants or crossed with Ldlr–/– …

INTRODUCTION: Whether circulating levels of sphingolipids are prospectively associated with cognitive decline and dementia risk is uncertain.

METHODS: We measured 14 sphingolipid species in plasma samples from 4488 participants (mean age 76.2 years; 40% male; and 25% apolipoprotein E (

RESULTS: Higher plasma levels of sphingomyelin-d18:1/16:0 (SM-16) were associated with a faster cognitive decline measured with 3MSE, in contrast, higher levels of sphingomyelin-d18:1/22:0 (SM-22) were associated with slower decline in cognition measured with DSST. In Cox regression, higher levels of SM-16 (hazard ration [HR] = 1.24 [95% confidence interval [CI]: 1.08-1.44]) and ceramide-d18:1/16:0 (Cer-16) (HR = 1.26 [95% CI: 1.10-1.45]) …

Prevalence And Patterns Of Cardiovascular Risk Factors In Young Hypertensive Patients, *Raghu V S R Tanuku Dr., Major Venkata Shree Krishna Dr., Sreedhar Tanuku Dr

Digital Journal of Clinical Medicine

Hypertension ranks among the top ten causes of mortality, with around 4% attributed to hypertensive complications. High salt intake, Type 2 diabetes, smoking, elevated serum lipids, a sedentary lifestyle, a diet heavy in saturated fat, genetic predisposition, as well as stress are among the factors that contribute to hypertension. Hypertension affects about 1 billion people worldwide, with considerable differences between populations and ethnic groups [2]. The Framingham Heart Study indicates that a person's lifetime risk of developing hypertension is 90% if they are normotensive at age 55. According to the NHANES IV (4th National Health and Nutrition Examination Survey), the …

We sought to characterize baseline cardiometabolic risk factors before thymic cancer diagnosis and the potential association between cancer treatment and subsequent cardiac events.

METHODS: This was a retrospective cohort study evaluating patients with thymic cancer from 2003 to 2020 compared to age- and sex-matched controls without cancer. Baseline cardiovascular risk factors, cancer characteristics, and incidence of cardiac events were collected from the health information exchange. Multivariable regression was used to examine the impact of cardiovascular risk …

Profound First-Degree Atrioventricular Block In A High-Level Basketball Athlete., Justin D Stumph, William K Cornwell, Michael A Rosenberg, Morteza Khodaee

Heart and Vascular Articles

First-degree atrioventricular (AV) block (PR interval >200 ms) is commonly observed among screening electrocardiogram (ECG) in athletes. Profound first-degree AV block (PR interval >400 ms) and Mobitz type I (Wenckebach) second-degree AV block are generally uncommon and often require further workup on a case-by-case basis, particularly when there is concern for a structural cardiac abnormality. In this case, we present an example of an asymptomatic profound first-degree AV block with Mobitz type I (Wenckebach) second-degree AV block. Transthoracic echocardiogram and stress echocardiogram were unremarkable and the patient was cleared to participate in sports without any restriction. Physicians managing athletes should …
