Hypertension Management: Improving Medication Adherence Through The Use Of Daily Text Messages, Gaelle Bulabula

Evidence-Based Practice Project Reports

Hypertension (HTN) is the leading cause of hospitalization and is responsible for approximately 50% of cardiovascular and cerebrovascular events (Al-Noumani, et al., 2018). Uncontrolled HTN can lead to comorbidities including ischemic heart disease, renal disease, or life-threatening arrythmias (World Health Organization [WHO], 2019). The leading cause of HTN is medication non-compliance (Varleta, et al., 2017). The purpose of this evidence-based practice project was to determine the effectiveness of daily text messages on antihypertensive medication adherence. A comprehensive review of literature generated ten high-level evidence studies demonstrating that daily text messages near each medication dosing time is best practice for improving …

The progress made over the past years in the field of cancer therapy has led to a significant decrease in cancer mortality, but these therapies have many adverse effects, cardiovascular effects being among the most frequent ones. For increasing lifelong expectancy of surviving cancer patients, cardiac monitoring represents an important task. Current studies and practice recommend echocardiography using strain analysis for monitoring the cardio toxic effects of cancer therapy. The potential of combining imaging techniques with biomarkers for the early detection and diagnosis seems a promising path for future research.

Periprocedural And In-Hospital Outcomes Among Percutaneous Coronary Intervention In Saphenous Vein Graft: A Retrospective Observational Study At A Tertiary Care Hospital In South Asian Country, Abdul Baqi, Sheema Saadia

Section of Cardiology

Background: Saphenous vein graft (SVG) may occlude either early or several months to years after coronary artery bypass graft (CABG) surgery. Doing re-do CABG surgery is associated with higher complication and mortality rate as compared to percutaneous coronary intervention (PCI) in SVG. However, PCI of SVG is associated with more periprocedural and in-hospital complications as compared to PCI of native coronary arteries. Due to the scarcity of local data in this regard, this study was designed to estimate the periprocedural and in-hospital outcomes among PCI in SVG.
Objectives: We aim to study the periprocedural and in-hospital outcomes among patients who …

Nanoanalytical Analysis Of Bisphosphonate-Driven Alterations Of Microcalcifications Using A 3d Hydrogel System And In Vivo Mouse Model, Jessica L. Ruiz, Joshua D. Hutcheson, Luis Cardoso, Amirala Bakhshian Nik, Alexandra Condado De Abreu, Tan Pham, Fabrizio Buffolo, Sara Busatto, Stefania Frederici, Andrea Ridolfi, Masanori Aikawa, Sergio Bertazzo, Paolo Bergese, Sheldon Weinbaum, Elena Aikawa

Publications and Research

Vascular calcification predicts atherosclerotic plaque rupture and cardiovascular events. Retrospective studies of women taking bisphosphonates (BiPs), a proposed therapy for vascular calcification, showed that BiPs paradoxically increased morbidity in patients with prior acute cardiovascular events but decreased mortality in event-free patients. Calcifying extracellular vesicles (EVs), released by cells within atherosclerotic plaques, aggregate and nucleate calcification. We hypothesized that BiPs block EV aggregation and modify existing mineral growth, potentially altering microcalcification morphology and the risk of plaque rupture. Three-dimensional (3D) collagen hydrogels incubated with calcifying EVs were used to mimic fibrous cap calcification in vitro, while an ApoE−/− mouse was used …

Pvn Activity In Cardiac Sympathetic Afferent Reflex (Csar) Control And Cardiovascular Function, Shane H. Boomer

Honors Thesis

Regulation of blood pressure is essential in bodily health. Hypertension and hypotension can be associated with varying diseases that could potentiate further disease. From this, understanding the mechanisms that regulate blood pressure is important within medicine. In my study, I will be focusing on a cardiovascular reflex that is less well understood, the cardiac sympathetic afferent reflex (CSAR). In particular, this work will examine sex differences in this reflex in overall function and in the involvement of an area of the brain called the paraventricular nucleus (PVN). We will test the hypothesis that there will be a significant difference between …

Mechanisms Of Synthetic Cannabinoids On Cardiovascular Health, Madeleine A. Nelson

Honors Thesis

Cannabinoids encompass natural cannabis and synthetic cannabinoids. While the synthetic cannabinoids interact with the same endogenous system as cannabis, their effects are quite different and poorly understood. In addition to psychological effects that trigger their use, these substances are linked to cardiovascular morbidity. To assess the cardiovascular effect of synthetic cannabinoids, we first tested the hypothesis that intravenous administration of a synthetic cannabinoid would increase blood pressure in conscious rats. Second, we tested the hypothesis that the sympathetic nervous system is involved by injecting a ganglion blocker to see if the cardiovascular response from synthetic cannabinoids would be blocked. Third, …

Community Health Sciences

Introduction: The creatinine-based Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) estimated glomerular filtration rate (eGFR) equation was calibrated for the general Pakistan population (eGFRcr-PK) to eliminate bias and improve accuracy. Cystatin C-based CKD-EPI equations (eGFRcys and eGFRcr-cys) have not been assessed in this population, and non-GFR determinants of cystatin C are unknown.
Methods: We assessed eGFRcys, eGFRcr-cys, and non-GFR determinants of cystatin C in a cross-sectional study of 557 participants (≥40 years of age) from Pakistan. We compared bias (median difference in measured GFR [mGFR] and eGFR), precision (interquartile range [IQR] of differences), accuracy (percentage of eGFR within 30% of mGFR), …

Sudden cardiac death (SCD) is an unexpected sudden death due to a heart condition, that occurs within one hour of symptoms onset. SCD is a leading cause of death in western countries, and is responsible for the majority of deaths from cardiovascular disease. Moreover, SCD accounts for mortality in approximately half of all coronary heart disease patients. Nevertheless, the recent advancements made in screening, prevention, treatment, and management of the underlying causes has decreased this number. In this article, we sought to review established and new modes of screening patients at risk for SCD, treatment and prevention of SCD, and …

Interplay Between Oxidative Stress, Sirt1, Reproductive And Metabolic Functions, Faiza Alam, Hareem Syed, Sofia Amjad, Mukhtiar Baig, Taseer Ahmed Khan, Rehana Rehman

Department of Biological & Biomedical Sciences

Silent information Regulators (SIRT1) gene stimulates antioxidants' expression, repairs cells damaged by oxidative stress (OS), and prevents the cells' dysfunction. In particular, the role of different Sirtuins, particularly SIRT1 in reproduction, has been widely studied over the past decade. Decreased SIRT 1 causes mitochondrial dysfunction by increasing Reactive Oxygen Species (ROS), lipid peroxidation, and DNA damage in both male and female gametes (Sperms and Oocytes), leading to infertility. In the female reproductive system, SIRT1 regulates proliferation and apoptosis in granulosa cells (GCs), and its down-regulation is associated with a reduced ovarian reserve. SIRT1 also modulates the stress response to OS …

We aimed to determine the association between PH and adverse in-hospital outcomes after acute ischemic stroke, as well as whether there are sex differences in this association. METHODS AND RESULTS: Acute ischemic stroke admissions from the US National Inpatient Sample between October 2015 and December 2017 were included. The relationship between PH and outcomes (mortality, prolonged hospitalization >4 days, and routine home …

Detection Of Myocardial Infarction Using Ecg And Multi-Scale Feature Concatenate, Jia-Zheng Jian, Tzong-Rong Ger, Han-Hua Lai, Chi-Ming Ku, Chiung-An Chen, Patricia Angela R. Abu

Department of Information Systems & Computer Science Faculty Publications

Diverse computer-aided diagnosis systems based on convolutional neural networks were applied to automate the detection of myocardial infarction (MI) found in electrocardiogram (ECG) for early diagnosis and prevention. However; issues; particularly overfitting and underfitting; were not being taken into account. In other words; it is unclear whether the network structure is too simple or complex. Toward this end; the proposed models were developed by starting with the simplest structure: a multi-lead features-concatenate narrow network (N-Net) in which only two convolutional layers were included in each lead branch. Additionally; multi-scale features-concatenate networks (MSN-Net) were also implemented where larger features were being …

Structural And Functional Properties Of Subsidiary Atrial Pacemakers In A Goat Model Of Sinus Node Disease, Luca Soattin, Zoltan Borbas, Jane Caldwell, Brian Prendergast, Akbar Vohra, Yawer Saeed, Andreas Hoschtitzky, Joseph Yanni, Andrew Atkinson, Sunil Jit Logantha

Section of Cardiology

Background: The sinoatrial/sinus node (SAN) is the primary pacemaker of the heart. In humans, SAN is surrounded by the paranodal area (PNA). Although the PNA function remains debated, it is thought to act as a subsidiary atrial pacemaker (SAP) tissue and become the dominant pacemaker in the setting of sinus node disease (SND). Large animal models of SND allow characterization of SAP, which might be a target for novel treatment strategies for SAN diseases.
Methods: A goat model of SND was developed (n = 10) by epicardially ablating the SAN and validated by mapping of emergent SAP locations through …
