Background

Chronic kidney disease (CKD) is increasingly recognized as a stroke risk factor, but its exact relationship with cerebrovascular disease is not well-understood. We investigated the development of cerebral small vessel disease using in vivo and in vitro models of CKD.

Methods

CKD was produced in aged C57BL/6J mice using an adenine-induced tubulointerstitial nephritis model. We analyzed brain histology using Prussian blue staining to examine formation of cerebral microhemorrhage (CMH), the hemorrhagic component of small vessel disease and the neuropathological substrate of MRI-demonstrable cerebral microbleeds. In cell culture studies, we examined effects of serum from healthy or CKD patients and …

Hypertrophic And Fibrotic Human Pkd Hearts Are Associated With Macrophage Infiltration And Abnormal Tgf-Β1 Signaling, Farideh Amirrad, Gregory A. Fishbein, Robert A. Edwards, Surya M. Nauli

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (PKD) is a hereditary kidney disorder which can affect cardiovascular system. Cardiac hypertrophy and cardiomyopathy in PKD have been reported by echocardiography analyses, but histopathology analyses of human PKD hearts have never been examined. The current studies evaluated human heart tissues from five subjects without PKD (non-PKD) and five subjects with PKD. Our histopathology data of human PKD hearts showed an increased extracellular matrix associated with cardiac hypertrophy and fibrosis. Hypertrophy- and fibrosis-associated pathways involving abnormal cardiac structure were next analyzed. We found that human PKD myocardium was infiltrated by inflammatory macrophage M1 and M2; …

To evaluate the cardiovascular outcomes of glucagon-like peptide-1 receptor agonists (GLP1-RA) in patients with type 2 diabetes (T2DM) and chronic kidney disease (CKD).

Materials and Methods

We searched PubMed, Ovid MEDLINE, CINAHL, and Web of Science databases for randomized controlled trials reporting event rates for a composite cardiovascular outcome of cardiovascular death, myocardial infarction, and stroke in patients with T2DM and CKD receiving GLP1-RA or placebo. Studies were restricted to those reporting specific event rates for patients with CKD separately from the overall population. We conducted a meta-analysis using a random-effects model. This meta-analysis was registered on PROSPERO (CRD42022320157). …

Cardio-Onco-Metabolism – Metabolic Vulnerabilities In Cancer And The Heart, Anja Karlstaedt, Heinrich Taegtmeyer

Faculty, Staff and Student Publications

Cancer and cardiovascular diseases (CVDs) are the leading cause of death worldwide. Metabolic remodeling is a hallmark of both cancer and the failing heart. Tumors reprogram metabolism to optimize nutrient utilization and meet increased demands for energy provision, biosynthetic pathways, and proliferation. Shared risk factors for cancer and CVDs suggest intersecting mechanisms for disease pathogenesis and progression. In this review, we aim to highlight the role of metabolic remodeling in cancer and its potential to impair cardiac function. Understanding these mechanisms will help us develop biomarkers, better therapies, and identify patients at risk of developing heart disease after surviving cancer.

Faculty, Staff and Students Publications

BACKGROUND: Higher arterial stiffness may contribute to future alterations in left ventricular systolic and diastolic function. We tested this hypothesis in individuals with youth-onset type 2 diabetes from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

METHODS: Arterial stiffness (pulse wave velocity [carotid-femoral, femoral-foot, and carotid-radial], augmentation index, brachial distensibility) was measured in 388 participants with type 2 diabetes (mean age, 21 years; diabetes duration, 7.7 ± 1.5 years). To reflect overall (composite) vascular stiffness, the five arterial stiffness measures were aggregated. An echocardiogram was performed in the same cohort 2 years later. Linear regression …

The Effect Of Age Concentration And Glucose Levels In Rage-Mediated Cardiac Fibroblast Migration In Type 2 Diabetes, Lorral Kanauss

Honors Theses

Diabetes is one of the largest health concerns in the United States. Its continuous increase in prevalence has led to it being one of the largest healthcare costs and consistently listed as one of the leading causes of death. That being said, diabetes also increases the risk of other health conditions, one of which is cardiovascular disease. Left ventricle hypertrophy resulting in the stiffening of the left ventricle and diastolic dysfunction is one form of cardiovascular disease associated with diabetes. Thought to be impacted by decreased fibroblast migration in the extracellular matrix, the experiments performed in this study seek to …

Mitochondrial Sirtuin-3 (Sirt3) Prevents Doxorubicin-Induced Dilated Cardiomyopathy By Modulating Protein Acetylation And Oxidative Stress, Mateusz M Tomczyk, Kyle G Cheung, Bo Xiang, Nahid Tamanna, Ana L Fonseca Teixeira, Prasoon Agarwal, Stephanie M Kereliuk, Victor Spicer, Ligen Lin, Jason Treberg, Qiang Tong, Vernon W Dolinsky

Faculty, Staff and Students Publications

BACKGROUND: High doses of doxorubicin put cancer patients at risk for developing dilated cardiomyopathy. Previously, we showed that doxorubicin treatment decreases SIRT3 (sirtuin 3), the main mitochondrial deacetylase and increases protein acetylation in rat cardiomyocytes. Here, we hypothesize that SIRT3 expression can attenuate doxorubicin induced dilated cardiomyopathy in vivo by preventing the acetylation of mitochondrial proteins.

METHODS: Nontransgenic, M3-SIRT3 (truncated SIRT3; short isoform), and M1-SIRT3 (full-length SIRT3; mitochondrial localized) transgenic mice were treated with doxorubicin for 4 weeks (8 mg/kg body weight per week). Echocardiography was performed to assess cardiac structure and function and validated by immunohistochemistry and immunofluorescence (n=4-10). …

Severe Mixed Mitral Valve Disease Due To Massive Mitral Annular Calcification: A Case Report And Literature Review, Fateh Ali Tipoo Sultan, Sheema Saadia

Section of Cardiology

We present an unusual case of massive mitral annular calcification (MAC) leading to severe mixed mitral valve disease, viz severe mitral regurgitation and severe mitral stenosis. To our knowledge, severe mixed mitral valve disease secondary to MAC is extremely rare. The patient (a 65-year-old lady) presented with worsening shortness of breath and signs of congestive heart failure. Echocardiographic examination revealed massive mitral annular calcification. Despite the massive annular calcification, she had experienced neither embolism nor endocarditis in the past. Because of severe symptomatic mitral regurgitation and mitral stenosis, surgery was advised; however, the patient declined it.

The Physiological Benefits Of A Plant-Based Diet On Cardiovascular Health, Jenevieve Petray

Nursing | Senior Theses

Cardiovascular disease (CVD) is increasingly more prevalent in today’s society and is attributed to an alarming percentage of American hospitalizations and deaths. Americans are unhealthier than ever before, and the main contributor is the Western diet. Diet is a double-edged sword that can offer benefits or detriments to one’s health. CVD encompasses numerous diagnoses originating from various underlying physiological alterations. These alterations are downstream effects of increased body weight and BMI, increased cholesterol levels, decreased insulin sensitivity and increased arterial plaque buildup. Research shows that a plant-based diet has the potential to manage and reverse all fundamental physiological alterations that …

Individuals with diabetes and peripheral artery disease have an increased risk of adverse cardiac and limb events, impairing the patient’s quality of life and causing long-term disability (Berger & Newman, 2020). Methods. During a 10-week period, these processes were implemented: (a) screening all patients …

Arrhythmogenic Hearts In Pkd2 Mutant Mice Are Characterized By Cardiac Fibrosis, Systolic, And Diastolic Dysfunctions, Farideh Amirrad, Rajasekharreddy Pala, Kiumars Shamloo, Brian S. Muntean, Surya M. Nauli

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (PKD) is a hereditary disorder affecting multiple organs, including the heart. PKD has been associated with many cardiac abnormalities including the arrhythmogenic remodeling in clinical evaluations. In our current study, we hypothesized that Pkd2 gene mutation results in structural and functional defects in the myocardium. The structural and functional changes of Pkd2 mutant hearts were analyzed in the myocardial-specific Pkd2 knockout (KO) mouse. We further assessed a potential role of TGF-b₁ signaling in the pathology of Pkd2-KO hearts. Hearts from age-matched 6-month-old MyH6•Pkd2^wt/wt (control or wild-type) and MyH6 …

Review Of Sexual Health Issues Linked With Cardiovascular Disease And Type 2 Diabetes Mellitus In Aboriginal And Torres Strait Islander Males, Veronica Collins, Tamara J. Swann, Jane Burns, Tim Moss, Mick Adams

Australian Indigenous HealthBulletin

There are well established links between male sexual health conditions and chronic disease, particularly cardiovascular disease (CVD) and type 2 diabetes (T2DM). Erectile dysfunction (ED) and low testosterone are two sexual health conditions that are relatively common among the wider male population. However, there is a lack of data specifically about these sexual problems among Aboriginal and Torres Strait Islander males.

One of the most important findings of research regarding the links between sexual health and chronic disease is that ED can be a risk marker for future CVD or undiagnosed T2DM. Understanding these links can lead to more holistic …

Loss Of Bone Morphogenetic Protein-Binding Endothelial Regulator Causes Insulin Resistance, Hua Mao, Luge Li, Qiying Fan, Aude Angelini, Pradip K Saha, Huaizhu Wu, Christie M Ballantyne, Sean M Hartig, Liang Xie, Xinchun Pi

Faculty, Staff and Students Publications

Accumulating evidence suggests that chronic inflammation of metabolic tissues plays a causal role in obesity-induced insulin resistance. Yet, how specific endothelial factors impact metabolic tissues remains undefined. Bone morphogenetic protein (BMP)–binding endothelial regulator (BMPER) adapts endothelial cells to inflammatory stress in diverse organ microenvironments. Here, we demonstrate that BMPER is a driver of insulin sensitivity. Both global and endothelial cell-specific inducible knockout of BMPER cause hyperinsulinemia, glucose intolerance and insulin resistance without increasing inflammation in metabolic tissues in mice. BMPER can directly activate insulin signaling, which requires its internalization and interaction with Niemann-Pick C1 (NPC1), an integral membrane protein that …

Ambulatory and Primary Care Articles

Coronavirus disease 2019 (COVID-19) is a global pandemic where several comorbidities have been shown to have a significant effect on mortality. Patients with diabetes mellitus (DM) have a higher mortality rate than non-DM patients if they get COVID-19. Recent studies have indicated that patients with a history of diabetes can increase the risk of severe acute respiratory syndrome coronavirus 2 infection. Additionally, patients without any history of diabetes can acquire new-onset DM when infected with COVID-19. Thus, there is a need to explore the bidirectional link between these two conditions, confirming the vicious loop between "DM/COVID-19". This narrative review presents …

Role Of Thymidine Phosphorylase In Type 2 Diabetes-Associated High-Risk Of Thrombosis, Adam Belcher

Theses, Dissertations and Capstones

Cardiovascular diseases (CVDs), such as ischemic heart disease and stroke, are the leading causes of death globally that disproportionally affects patients with type 2 diabetes mellitus (T2DM) at a 2-4-fold rate compared to non-diabetic patients. These CVDs result from a blood clot, also known as a thrombus, formed in arteries that can block blood flow resulting in tissue damage and death. Antiplatelet drugs, such as aspirin and clopidogrel, used to prevent thrombosis have been found to be less effective in diabetics and increase the risk of hemorrhagic events. The T2DM epidemic has made it imperative to find therapies that decrease …

Diabetes Debunked: What You Need To Know, Maggie Hutson

Honors Program: Senior Projects (Public)

The goal of this Honors creative project is to encourage health literacy in populations who are curious about Type 2 Diabetes or have Type 2 Diabetes. From personal experience, I have seen noncompliance in diabetics and wondered why since it is a serious, progressive disease. After researching, I found that some diabetics do not understand the scope of their disease, especially since many of the dangerous complications that arise from Type 2 Diabetes do not present until later in the disease when it is too late. For my senior project, I decided to write an educational paper as a supplement …

Using The Adam Questionnaire In Primary Care To Identify Hypoandrogenism In Males Aged 40 Years Or Older, Jeremy Burns

Doctor of Nursing Practice

Testosterone replacement therapy (TRT) has been shown to improve the symptoms of metabolic syndrome by reducing Hemoglobin A1C, belly fat, cholesterol, and blood pressure (Cunningham, 2015). The ultimate goal for testosterone-deficient patients is to have an improved quality of life by starting TRT. This quality improvement project was conducted at a small primary care clinic in South Texas. The project was started by screening 84 male patients ≥ 40 years of age using the Androgen Deficiency in Aging Males (ADAM) questionnaire. The ADAM questionnaire was considered positive for anyone who answered “yes” to 3 or more questions or “yes” to …

The Acute Effect Of Water Intake On Glucose Regulation In Low Drinkers, Adam David Seal
