Utility Of The Motivation To Change Lifestyle And Health Behaviors For Dementia Risk Reduction Scale (Mclhb-Drr) Based On A North American Sample, Angelina E. Witbeck

Dissertations

As the population ages, the prevalence rates of dementia continue to increase. Without a cure or promising treatment for dementia, the best course of lowering the prevalence rates of dementia is through preventative measures. Through an electronic survey, the study utilized the MCLHB-DRR scale to determine whether (1) gender, age, educational background, and socioeconomic status will impact the motivational factors to change lifestyle and health behaviors to reduce the risk of developing dementia and (2) direct experiences with individuals that have a dementia diagnosis are likely to impact one's motivational factors to change lifestyle and health behaviors to reduce the …

Faculty, Staff and Student Publications

BACKGROUND: We sought to better understand patterns of potentially inappropriate medications (PIMs) from the Beers criteria among older adults hospitalized with heart failure (HF). This observational study of hospitalizations was derived from the geographically diverse REasons for Geographic and Racial Differences in Stroke cohort.

METHODS AND RESULTS: We examined participants aged 65 years and older with an expert-adjudicated hospitalization for HF. The Beers criteria medications were abstracted from medical records. The prevalence of PIMs was 61.1% at admission and 64.0% at discharge. Participants were taking a median of 1 PIM (interquartile range [IQR] 0-1 PIM) at hospital admission and a …

BACKGROUND: Large variation exists for out-of-hospital-cardiac-arrest (OHCA) prehospital care, but less is known about variations in post-arrest care. We sought to evaluate variation in post-arrest care in Texas as well as factors associated with higher performing hospitals.

METHODS: We analyzed data in Texas Cardiac Arrest Registry to Enhance Survival (TX-CARES), including all adult, non-traumatic OHCAs from 1/1/2014 through 12/31/ 2020 that survived to hospital admission. We first evaluated variability in provisions of post-arrest care and outcomes. We then stratified hospitals into quartiles based on their rate of survival and evaluated the association between improving quartiles and care. Lastly, we evaluated …

The Influence Of Demographic, Social, And Economic Factors On Referral For Heart Failure Services, Catherine Elaine Kelty

Dissertations

Patients with end-stage advanced heart failure must go through an extensive evaluation process before being selected for either heart transplantation or left ventricular assist device (LVAD). This evaluation not only assesses a patient’s medical need for advanced heart failure treatments but also includes an assessment of psychosocial and economic factors that may affect a patient’s success post-treatment. While it is important to allocate scarce resources, such as donated organs, to the patients who will benefit the most, there is also a need for equity in the allocation of and access to healthcare services. This raises the question of whether patients …

Midlife Determinants Of Healthy Cardiovascular Aging: The Atherosclerosis Risk In Communities (Aric) Study, Xiaoming Jia, Caroline Sun, Vijay Nambi, Salim S Virani, George Taffet, Eric Boerwinkle, Jan Bressler, Chiadi Ndumele, B Gwen Windham, James A De Lemos, Kunihiro Matsushita, John William Mcevoy, Ron C Hoogeveen, Elizabeth Selvin, Christie M Ballantyne

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: Risk factor cutoffs are derived from associations with clinical cardiovascular disease (CVD), but how these risk factors associate with preserved cardiovascular health into old age is not well studied. We investigated midlife determinants of healthy versus nonhealthy cardiovascular aging in the Atherosclerosis Risk in Communities (ARIC) study.

METHODS: ARIC participants were categorized by cardiovascular status in older age (mean age 75.8 ± 5.3 years, range 66-90): healthy, subclinical disease (assessed by biomarkers and left ventricular function), clinical CVD (coronary heart disease, stroke, or heart failure), or prior death. We examined associations of midlife (mean age 52.1 ± …

Relationship Between Arterial Stiffness And Subsequent Cardiac Structure And Function In Young Adults With Youth-Onset Type 2 Diabetes: Results From The Today Study, Amy S Shah, Samuel S Gidding, Laure El Ghormli, Jeanie B Tryggestad, Kristen J Nadeau, Fida Bacha, Lorraine E Levitt Katz, Steven M Willi, Joao Lima, Elaine M Urbina

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 …

Faculty, Staff and Students Publications

STUDY OBJECTIVE: To evaluate whether the introduction of a 1-hour high-sensitivity cardiac troponin-T (hs-TnT) pathway for patients who present to the emergency department (ED) with suspected acute coronary syndrome (ACS) improves ED patient flow without changing the rate of "missed" major adverse cardiac events (MACE), compared to use of conventional cardiac troponin with an associated 3-hour pathway.

METHODS: This was a prospective, uncontrolled observational study conducted before and after implementation of a 1-hour hs-TnT pathway at a high-volume urban ED. Patients undergoing evaluation for ACS in the ED were enrolled during their initial visit and clinical outcomes were assessed at …

Peripheral Extracorporeal Membrane Oxygenation Support Expands The Application Of Robot-Assisted Coronary Artery Bypass, Vivek Patel, Zachary Gray, Mahboob Alam, Guilherme Vianna Silva, Leo Simpson, Kenneth Liao

Faculty, Staff and Students Publications

OBJECTIVE: Robot-assisted coronary artery bypass (RCAB) is typically not offered to higher risk patients with reduced cardiopulmonary function, critical coronary artery disease, and challenging chest wall anatomy. In this study, we report the novel use of nonemergency intraoperative peripheral extracorporeal membrane oxygenation as partial cardiopulmonary support during RCAB for patients who were considered high-risk candidates for conventional CAB and at the same time not eligible for RCAB without cardiopulmonary support.

METHODS: Forty-five high risk patients (mean age, 68 years; Society of Thoracic Surgeons score, 6.27%; ejection fraction, 45%) underwent RCAB with nonemergency peripheral extracorporeal membrane oxygenation support for the following …

Lmod2-Related Dilated Cardiomyopathy Presenting In Late Infancy, Erica Lay, Mahshid S Azamian, Susan W Denfield, William Dreyer, Joseph A Spinner, Debra Kearney, Lilei Zhang, Kim C Worley, Weimin Bi, Seema R Lalani

Faculty, Staff and Students Publications

Leiomodin-2 (LMOD2) is an important regulator of the thin filament length, known to promote elongation of actin through polymerization at pointed ends. Mice with Lmod2 deficiency die around 3 weeks of age due to severe dilated cardiomyopathy (DCM), resulting from decreased heart contractility due to shorter thin filaments. To date, there have been three infants from two families reported with biallelic variants in LMOD2, presenting with perinatal onset DCM. Here, we describe a third family with a child harboring a previously described homozygous frameshift variant, c.1243_1244delCT (p.L415Vfs*108) with DCM, presenting later in infancy at 9 months of age. Family history …

A Novel Automated Junctional Ectopic Tachycardia Detection Tool For Children With Congenital Heart Disease, Jamie L S Waugh, Raajen Patel, Yilong Ju, Ankit B Patel, Craig G Rusin, Parag N Jain

Faculty, Staff and Students Publications

BACKGROUND: Junctional ectopic tachycardia (JET) is a prevalent life-threatening arrhythmia in children with congenital heart disease (CHD), with marked resemblance to normal sinus rhythm (NSR) often leading to delay in diagnosis.

OBJECTIVE: To develop a novel automated arrhythmia detection tool to identify JET.

METHODS: A single-center retrospective cohort study of children with CHD was performed. Electrocardiographic (ECG) data produced by bedside monitors is captured automatically by the Sickbay platform. Based on the detection of R and P wave peaks, 2 interpretable ECG features are calculated: P prominence median and PR interval interquartile range (IQR). These features are used as input …

A Rare Presentation Of Pericardial Tumor Presenting As Chronic Cough, Swarup Sharma Rijal, William H. Risher, Aakankshya Kharel, Upendra Kaphle

Advances in Clinical Medical Research and Healthcare Delivery

Chronic cough can pose various diagnostic and therapeutic dilemmas to physicians. Airway narrowing secondary to endoluminal disease or extrinsic compression are known etiologies of chronic cough. We report an extremely rare case of chronic cough due to extrinsic airway compression by a large pericardial lipoma with subsequent resolution of symptoms after the resection of the mass. This case provides insight into the rare etiology of chronic cough that is addressable with surgical intervention.

Poloxamer 407 Induces Hypertriglyceridemia But Decreases Atherosclerosis In Ldlr -/- Mice, Xueying Peng, Zeqin Lian, Xiao-Yuan Dai Perrard, Yunjie Xiao, Jing Ni, Veronica O'Brien, Henry Dong, Henry J Pownall, Christie M Ballantyne, Huaizhu Wu

Faculty, Staff and Students Publications

Background: Hypertriglyceridemia (HTG) increases the risk for atherosclerotic cardiovascular disease, but underlying mechanisms are incompletely understood. Circulating monocytes play an important role in atherogenesis by infiltrating arterial walls, where they differentiate into macrophages. We tested the hypothesis that HTG is mechanistically linked to atherogenesis by altering the monocyte phenotype and infiltration into atherosclerotic lesions in a model of diet-induced atherogenesis in Ldlr−/− mice. Methods: HTG was induced in male Ldlr−/− mice, fed a Western, high-fat high-cholesterol diet, by daily injection of poloxamer 407 (P407), a lipoprotein lipase inhibitor, for seven weeks. Atherosclerosis, monocyte phenotypes, and monocyte migration into atherosclerotic lesions …

Crel And Wnt5a/Frizzled 5 Receptor-Mediated Inflammatory Regulation Reveal Novel Neuroprotectin D1 Targets For Neuroprotection, Jorgelina M. Calandria, Khanh V. Do, Sayantani Kala-Bhattacharjee, Andre Obenaus, Ludmila Belayev, Nicolas G. Bazan

School of Medicine Faculty Publications

Abstract: Wnt5a triggers inflammatory responses and damage via NFkB/p65 in retinal pigment epithelial (RPE) cells undergoing uncompensated oxidative stress (UOS) and in experimental ischemic stroke. We found that Wnt5a-Clathrin-mediated uptake leads to NFkB/p65 activation and that Wnt5a is secreted in an exosome-independent fashion. We uncovered that docosahexaenoic acid (DHA) and its derivative, Neuroprotectin D1 (NPD1), upregulate c-Rel expression that, as a result, blunts Wnt5a abundance by competing with NFkB/p65 on the Wnt5a promoter A. Wnt5a increases in ischemic stroke penumbra and blood, while DHA reduces Wnt5a abundance with concomitant neuroprotection. Peptide inhibitor of Wnt5a binding, Box5, is also neuroprotective. DHA-decreased …

Alterations Of The Gut Microbial Community Structure And Function With Aging In The Spontaneously Hypertensive Stroke Prone Rat, Huanan Shi, James W Nelson, Sharon Phillips, Joseph F Petrosino, Robert M Bryan, David J Durgan

Faculty, Staff and Students Publications

Gut dysbiosis, a pathological imbalance of bacteria, has been shown to contribute to the development of hypertension (HT), systemic- and neuro-inflammation, and blood-brain barrier (BBB) disruption in spontaneously hypertensive stroke prone rats (SHRSP). However, to date individual species that contribute to HT in the SHRSP model have not been identified. One potential reason, is that nearly all studies of the SHRSP gut microbiota have analyzed samples from rats with established HT. The goal of this study was to examine the SHRSP gut microbiota before, during, and after the onset of hypertension, and in normotensive WKY control rats over the same …

The Impact Of Social Determinants Of Health On Hypertension, Lakenya Forthner

Doctoral Projects

ABSTRACT

Nearly 43% of African American men have Hypertension (HTN). HTN is a major reversible health problem for young adult, African American males. Identifying health behaviors to enhance longevity is essential due to the “excess burden of preventable, chronic diseases and premature death among African American men. The “role of social determinants of health (SDOH) on outcomes, and the possible role these determinants play in disparities have largely been ignored” (Haggart, 2018, pp. 2, 8).

Interventions that address SDOH must take a multicomponent approach. Evidence has been established that adhering to a healthy lifestyle reduces the burdens and risks associated …

Office of the Provost

Background: Whether the association of cardiovascular diseases (CVDs) with dementia differs by sex remains unclear, and the role of socioeconomic, lifestyle, genetic, and medical factors in their association is unknown.
Methods: We used data from the UK Biobank, a population-based cohort study of 502,649 individuals. We used Cox proportional hazards models to estimate sex-specific hazard ratios (HRs) and 95% confidence intervals (CI), and women-to-men ratio of HRs (RHR) for the association between CVD (coronary heart diseases (CHD), stroke, and heart failure) and incident dementia (all-cause dementia, Alzheimer's Disease (AD), and vascular dementia (VD)). The moderator roles of socioeconomic (education, income), …

Building An Artificial Intelligence Framework For Hypertension Diagnosis: A Use Case Of The Problem List Curation, Ketemwabi Yves Shamavu

Theses & Dissertations

Hypertension is the world's leading factor in cardiovascular disease. Forty-seven percent or close to one in two Americans aged 18 and older are affected. It predicts approximately a thousand deaths per day. Based on recent statistics from the Centers for Disease Control and Prevention, one in three patients with hypertension does not know they are hypertensive. Seventy-five percent of hypertensive patients have uncontrolled hypertension - meaning that they are not treated to target. While there is extensive literature on hypertension diagnosis and management, there is an apparent gap in understanding and acknowledging that a person is hypertensive. Moreover, blood pressure …
