Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows

Electronic Theses and Dissertations

Adipose tissue can be characterized as either being a white (energy storing) depot or a brown (energy expending) depot and both have been found to contain dense networks of neural innervation. This adipose nerve supply regulates numerous metabolic functions and likely plays an important role in the function of adipose blood vessels. Recently our lab has shown in the C57BL/6 mouse model that peripheral neuropathy, or the dying back and dysfunction of the nerves in the superficial tissues such as the skin, can extend into the subcutaneous adipose tissue in conditions commonly associated with the neuropathic phenotype (i.e. diabetes, obesity, …

Defining The Role Of Tyrosine Phosphorylation In The Regulation Of Connexin43 In Cardiac Diseases, Li Zheng

Theses & Dissertations

Connexins are integral membrane proteins that oligomerize to form gap junction channels. Ions and small molecules diffuse intercellularly through these channels, allowing individual cellular events to synchronize into the functional response of an entire organ. Gap junction channels composed of Connexin43 (Cx43) mediate electrical coupling and impulse propagation in the normal working myocardium. In the failing heart, Cx43 remodeling (decreased expression, altered phosphorylation state, loss at intercalated discs, and increased presence at lateral membranes) contributes to rhythm disturbances and contractile dysfunction. While there is considerable information regarding key interactions of Cx43 in the regulation of gap junction channels, unfortunately, the …

Marijuana And Its Cardiovascular Implications, Albert Bui, Daniel Powell, Victoria Cho, Kelsey Lindsley, Lindsey Peters

Pharmacy and Wellness Review

As marijuana becomes legalized for medical use, it is important for prescribers and pharmacists to be knowledgeable about the important aspects of marijuana such as mechanism of action, indications and abuse potential. Although marijuana's medicinal benefits are frequently reported, the risks, namely cardiovascular risks, associated with its utilization are often overlooked. Use of marijuana has been reported to increase the risk of myocardial infarction, tachycardia and hypotension, among others. Health care providers must determine if marijuana's benefits outweigh such risks when marijuana therapy is an option. It is also important for pharmacists to understand how to successfully counsel patients using …

Management Of Hypertensive Emergencies In Pediatrics, Jennifer L. Bauer, Jamie L. Amero, Amanda C. Mcdavid, Ryan A. Fischer, Alison L. Huet, Karen L. Kier

Pharmacy and Wellness Review

As hypertension becomes more prevalent in the pediatric population, clinicians are more likely to encounter hypertensive emergencies in children, which require pharmacists and physicians to be educated on the therapeutic options for these emergencies. However, the strict governmental requirements on the testing of these drugs in pediatric patients have limited the amount of available evidence on which to base clinical decisions. This review will highlight the available evidence and preferred treatment options for the management of pediatric hypertensive emergencies.

A Review Of Dabigatran, An Oral Anticoagulant, Lindsey A. Hallman, Chad A. Rounds, Rebecca A. Carey, Nicole R. Hume, Karen L. Kier, James Spicer

Pharmacy and Wellness Review

Serious clinical complications associated with venous thrombotic embolism (VTE) necessitate prophylaxis in patient groups who are at high risk of VTE, specifically those recovering from orthopedic surgery with atrial fibrillation, with mechanical heart valves, at increased risk for stroke, or recovering post-MI. Currently, prophylaxis with warfarin, enoxaparin, or fondaparinux has been the standard of therapy, but these therapies each have their limitations. Dabigatran etexilate is an orally available pro-drug of dabigatran, a competitive, reversible, direct inhibitor thrombin (Factor lla). The agent is converted by esterases, and, thus, not associated with the complications of the CYP enzyme system. Dabigatran follows a …

Junctophilin-2 Protects Cardiomyocytes Against Palmitate-Induced Injury, Xiaoyun Ji

Electronic Thesis and Dissertation Repository

Cardiac lipotoxicity may induce cardiomyocyte apoptosis, eventually leading to myocardial dysfunction and heart failure. This study investigated whether and how junctophilin-2 (JPH2) plays a role in palmitate-induced apoptosis in cardiomyocytes. Here, we found palmitate incubation reduced JPH2 protein levels, increased cytosolic Ca²⁺ and induced apoptosis in cardiomyocytes. JPH2 over-expression prevented the increased cytosolic Ca²⁺ and apoptosis in palmitate-stimulated cardiomyocytes. JPH2 over-expression also attenuated palmitate-induced CCAAT-enhancer-binding protein homologous protein (CHOP) expression and CHOP deletion alleviated palmitate-induced apoptosis. Furthermore, blocking Ca²⁺ release from ryanodine receptor-2 (RyR2) prevented palmitate-stimulated CHOP induction and apoptosis. Additionally, JPH2 silencing elevated cytosolic Ca^{2+ …}

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

Graduate Theses and Dissertations

Previous evidence suggests the hormone arginine vasopressin (AVP) may be a modifiable factor contributing to hyperglycemia. Significant differences in urine concentration and copeptin, a marker for AVP, have been observed between low and high water drinkers. Purpose: The purpose was to investigate the acute effect of adequate water intake on glucose regulation in low drinkers. Methods: 7 healthy (5 males, 2 female) low drinkers were recruited using a water frequency questionnaire (WFQ), spot and 24-h urine sample (age 43±6 y, BMI 30.9±3, WFQ volume 823±403 mL∙d-1, 24 h Uosm 961±105 mmol∙kg-1, copeptin 8.17±3.05 pmol∙L-1). During two experimental protocols, participants remained …

Listen To Your Heart, Or At Least Theirs: Maintaining A High Index Of Suspicion For Infective Endocarditis, Mollie Powell Do, Mahesh Setty Md

Emergency Medicine

After an endothelial injury, a fibrin and platelet cap forms. This cap is typically sterile but in times of infection can become colonized by microbes leading to a vegetation. When this occurs on the endothelium of the heart, it is termed infective endocarditis (IE). IE is a difficult diagnosis to make in the ED. The symptoms are vague. Classic exam findings are often absent, murmur auscultation can be challenging and there is not a single diagnostic test. A delayed or missed diagnosis can be fatal; therefore, it is essential that ED physicians maintain a high index of suspicion in high …

Pharmacy and Wellness Review

Anticoagulants are a well-known class of agents essential for the prevention of blood clots, which may further develop into deep vein thrombosis, pulmonary embolism or stroke. Individuals at a high risk of clotting, such as those with atrial fibrillation, multiple risk factors or recent hip/knee surgery, are in need of long-term anticoagulation therapy. The purpose of this review is to highlight the pros and cons for each available anticoagulant as well as discuss pivotal clinical trials that evaluated the safety and efficacy of these agents. Warfarin, the oldest anticoagulant, requires the patient to attend frequent appointments with a health care …

Pcsk9 Inhibitors: A Novel Class Of Pharmacotherapy For Hypercholesterolemia, Angela Chu, Austin Hilverding, Elizabeth Kramer, Brendan Rasor, Boyd Rorabaugh

Pharmacy and Wellness Review

The recent U.S. Food and Drug Administration (FDA) approval of two new drugs, alirocumab (Praluent®) and evolocumab (Repatha®) is a breakthrough in the treatment of familial hypercholesterolemia. These drugs are a part of a new class called the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors that act by increasing the number of low density lipoprotein receptors (LDL-R) recycled to hepatocyte membranes. The increased density of LDL-R facilitates greater clearance of low density lipoproteins from the blood. Numerous clinical trials have demonstrated the efficacy of these agents, particularly for patients in whom standard cholesterol-lowering therapy is insufficient. However, data on long-term …

Combined Neprilysin And Angiotensin Inhibitor For The Treatment Of Heart Failure, Albert Bui, Victoria Cho, Rebecca Worden, Haley Armstrong, Rachel Pucel, Lindsey Peters

Pharmacy and Wellness Review

Heart failure (HF) is a highly prevalent disease state worldwide that can progress into a disabling condition. It is pertinent to have a treatment regimen that is effective in lowering the number of HF exacerbations and, therefore, hospital readmission rates. A novel medication currently in clinical trials, LCZ696, blocks both neprilysin and angiotensin type I receptors. The overall effects are an inhibition of the breakdown of natriuretic peptides which leads to a decrease in renin and aldosterone release. This, combined with the antagonization of angiotensin type I receptors, leads to a decrease in blood pressure, blood volume and systemic vascular …

A Comparison Of Mipomersen (Kynamro®) And Lomitapide (Juxtapid®): Medications For The Treatment Of Homozygous Familial Hypercholesterolemia, Ann Marie Ruhe, Austin Brown, Ginny Daniels, Kelsey Fink, David Bright

Pharmacy and Wellness Review

Homozygous familial hypercholesterolemia (HoFH) is a rare disease that involves mutations in the genes coding for low density lipoprotein (LDL) receptors, preventing the uptake of LDL cholesterol from the serum and resulting in extremely high cholesterol levels.1 Between December 2012, and January 2013, two orphan drugs were approved by the U.S. Food and Drug Administration (FDA) for the treatment of HoFH. Mipomersen (Kynamro®) is a subcutaneous injection that functions as an antisense oligonucleotide inhibitor and ultimately prevents the translation of mRNA coding for apolipoprotein B (apoB)-100 which binds to LDL and very low density lipoprotein (vLDL) cholesterol.7 Lomitapide (Juxtapid®) is …

Novel Oral Anticoagulants: A Comparative Study Of The Clinical Potential For Dabigatran, Rivaroxaban, And Apixaban Versus Warfarin, Lindsay Mark, Joanne Tran, Zachary Jones, Jessica Beck, David Bright

Pharmacy and Wellness Review

Although Coumadin® (warfarin) has been the standard outpatient anticoagulant for long-term prevention of thrombosis for many decades, it presents with significant challenges for both patients and health care providers in optimizing standards of care including dietary and drug restrictions, regular monitoring of the patient's International Normalized Ratio (INR), and difficulty maintaining therapeutic levels. Despite its unmistakable effectiveness, there has been an interest from the medical community in developing potential alternative drug therapies. As a result, within the past three years the U.S. Food and Drug Administration (FDA) has approved the use of three new oral anticoagulant drugs (dabigatran, rivaroxaban, and …

Sildenafil As An Appropriate Monotherapy Option In The Treatment Of Pulmonary Arterial Hypertension (Pah), Kaitlin Horton, Kent Wilin, Sarah Ginty, Lara Long, David Bright

Pharmacy and Wellness Review

Pulmonary arterial hypertension (PAH) is a debilitating disease characterized by constriction in the diameter of the pulmonary arterial lumen.1,2 This leads to increased pressure and stress on the right ventricle of the heart, which may lead to heart failure and death.2,3 Currently there are only a few treatment options for patients with PAH. Sildenafil, a phosphodiesterase type 5 (PDE-5) inhibitor, can be used to treat PAH. Sildenafil inhibits the degradation of cyclic guanosine monophosphate (cGMP). Increased cGMP concentration results in pulmonary vasculature relaxation. Current clinical trials have indicated that sildenafil can significantly improve many of the symptoms of PAH. The …

Dronedarone: An Update To A Controversial Therapy For Atrial Fibrillation, Zachary Crawford, Sara Mcallister, Amanda Hoersten, Jennifer Bauer, Megan Keller, David Bright

Pharmacy and Wellness Review

As of 2004, it was estimated that 2.2 million Americans were diagnosed with paroxysmal or persistent atrial fibrillation (AF) resulting in one out of every six strokes in the United States. AF leads to a reduction in pumping efficiency of the heart increasing the risk of several serious sequelae such as thromboembolic stroke and congestive heart failure (CHF). It also results in a reduced quality of life for the patients suffering from the disease. Patients with AF require appropriate antiarrhythmic therapy to control symptoms and prevent adverse effects of the condition. Multaq® (dronedarone), an antiarrhythmic drug approved for AF in …

BACKGROUND: While echocardiographic parameters are used to quantify ventricular function in infants with single ventricle physiology, there are few data comparing these to invasive measurements. This study correlates echocardiographic measures of diastolic function with ventricular end-diastolic pressure in infants with single ventricle physiology prior to superior cavopulmonary anastomosis.

METHODS: Data from 173 patients enrolled in the Pediatric Heart Network Infant Single Ventricle enalapril trial were analysed. Those with mixed ventricular types (n = 17) and one outlier (end-diastolic pressure = 32 mmHg) were excluded from the analysis, leaving a total sample size of 155 patients. Echocardiographic measurements were correlated to …
