The Economic Value Of Pharmacist-Physician Collaborative Care Models In Hypertension Management, Jessica S. Jay

Theses and Dissertations

Background: Hypertension is highly prevalent in the United States, affecting nearly half of all adults (43%). Studies have shown that pharmacy-physician collaborative care models (PPCCM) for hypertension management significantly improve blood pressure (BP) control rates and provide consistent control of BP. Time in target range (TTR) for systolic BP is a novel measure of BP control consistency that is independently associated with decreased cardiovascular (CV) risk. There is no evidence observed improvement in TTR for systolic BP with PPCCM is cost effective.

Objective: This study aimed to compare the cost-effectiveness of PPCCM with usual care for the management of hypertension …

Tummy Time In Infancy: Real-World Assessments And Associations With Developmental Outcomes In Early Childhood, Ketaki Inamdar

Theses and Dissertations

Tummy time or awake, supervised, prone play is an important developmental play position in infancy. Engaging in more than 15 minutes of tummy time per day is associated with a lower risk of plagiocephaly, lower body mass index, and achievement of higher motor scores in full-term and at-risk preterm infants. However, there are significant gaps in the measurement of tummy time in current literature. Conventionally used subjective parent reports have not been validated against gold standard direct observation, and the feasibility and real-world validity of objective solutions such as wearable sensors has not been examined in full-term and at-risk preterm …

Targeting Bcl-2 Family Proteins In Therapy Induced Senescent Cancer Cell Models, Wade Cook

Theses and Dissertations

Non-small Cell Lung Cancer (NSCLC) originates from numerous different cell types in the lungs and is among the deadliest of cancers. Head and Neck Squamous Cell Carcinomas (HNSCC) are derived from the mucosal membranes of the oral cavity, pharynx, and larynx. Both NSCLC and HNSCC are predominately caused by tobacco smoke inhalation and as such mutations in the tumor suppressor gene TP53 are common. Since similarities exist in the root cause of NSCLC and HNSCC, they may also share similarities in treatment methods. Cisplatin is a platinum-based DNA damaging agent that has been used as a cancer chemotherapy for decades. …

Journal Articles: Epidemiology

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) ranks first among liver diseases in Western countries. NAFLD is typically associated with obesity and diabetes, however it also develops in lean individuals without metabolic syndrome. The prevalence of lean NAFLD is 7 percent in the U.S. and 25-30 percent in some Asian countries. NAFLD starts with excess liver fat accumulation (NAFL), progresses to nonalcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC). The pathogenesis of lean NASH-HCC and how it differs from obese NASH-HCC is not well understood.

METHODS: In this work, we generated a mouse model of lean and obese NASH-HCC using a …

Loss Of Smad4 Is Associated With Poor Tumor Immunogenicity And Reduced Pd-L1 Expression In Pancreatic Cancer, Daniel R. Principe, Patrick W. Underwood, Sandeep Kumar, Kaytlin E. Timbers, Regina M. Koch, Jose G. Trevino, Hidayatullah G. Munshi, Ajay Rana

Surgery Publications

Transforming Growth Factor β (TGFβ) is a key mediator of immune evasion in pancreatic ductal adenocarcinoma (PDAC), and the addition of TGFβ inhibitors in select immunotherapy regimens shows early promise. Though the TGFβ target SMAD4 is deleted in approximately 55% of PDAC tumors, the effects of SMAD4 loss on tumor immunity have yet to be fully explored. Using a combination of genomic databases and PDAC specimens, we found that tumors with loss of SMAD4 have a comparatively poor T-cell infiltrate. SMAD4 loss was also associated with a reduction in several chemokines with known roles in T-cell recruitment, which was recapitulated …

Acute Ethanol-Induced Liver Injury Is Prevented By Betaine Administration, Madan Kumar Arumugam, Srinivas Chava, Sathish Kumar Perumal, Matthew C. Paal, Karuna Rasineni, Murali Ganesan, Terrence Donohue, Natalia A. Osna, Kusum K. Kharbanda

Journal Articles: Internal Medicine

Binge drinking is the most common form of excessive alcohol use. Repeated episodes of binge drinking cause multiple organ injuries, including liver damage. We previously demonstrated that chronic ethanol administration causes a decline in the intrahepatic ratio of S-adenosylmethionine (SAM) to S-adenosylhomocysteine (SAH). This decline causes impairments in essential methylation reactions that result in alcohol-induced fatty liver (steatosis) and other features of alcohol-associated liver disease (ALD). Co-treatment with betaine during chronic ethanol feeding, normalizes hepatocellular SAM:SAH ratio and alleviates many features of liver damage including steatosis. Here, we sought to examine whether betaine treatment similarly protects against liver injury in …

Aims: To examine the secular trends of stunting, underweight and overweight in children aged < 5 years in Kuwait between 2007 and 2019.

Methods: We used large individual data records (n=48 108) from the Kuwait Nutritional Surveillance System (KNSS) to calculate height/length-for-age z score (HAZ), weight-for-age z score and body mass index (BMI)-for-age z score using World Health Organization growth references. Stunting and underweight were defined as less than -2 standard deviation (SD) and overweight (including obesity) as ≥ 2 SD. Trends of stunting, underweight and overweight were …

Biomarkers Of Inflammation And Oxidative Stress In The Prediction And Management Of Acute Coronary Syndrome, Udaya Ralapanawa, Sivakanesan R

Health Sciences

The assessment of patients presenting with chest pain or symptoms indicative of cardiac ischemia remains a diagnostic challenge. Many types of research have focused on the search for ideal biological markers for the rapid detection of cardiac cell injuries. Markers of inflammation and oxidative stress are the way forward. At present, the biomarker most widely used for diagnosing acute coronary syndrome is cardiac troponin though it has some limitations. Apart from cardiac troponin, several other biomarkers, especially inflammation and oxidative stress markers in acute coronary syndrome, have been investigated. However, most of them still require validation in further studies. As …

Status Anxiety And Overall Life Satisfaction Of Young Adults In The Bay Area, Samuel Casco

Global Public Health | Senior Theses

The published literature suggests social comparisons have significant negative effects on an individual’s psychological well-being. However, there is little to no research to suggest that an individual’s attainment of societal success has a relationship with one’s perceived life satisfaction.

A mixed-methods study involved young adults ages 18-29 in the Bay Area and were selected via a student researcher in the Global Public Health department of Dominican University of California. 115 participants completed surveys regarding self-perceived life satisfaction and status anxiety through the Qualtrics Survey Collection Tool. A Pearson’s Chi-Squared Test was conducted to find an association between life satisfaction and …

The Role Of Glis3 In Zebrafish Endocrine Development And Regeneration, Tasha Swenney

Murray State Theses and Dissertations

Maintenance of proper blood glucose homeostasis is governed by the endocrine cells of the pancreas. Dysregulation of blood glucose is characteristic of the disease, diabetes mellitus. Relatively little is known about the molecular mechanisms that underlie diabetes. The genes associated with more common forms of diabetes remain more enigmatic and likely have less direct roles in blood glucose homeostasis such as glucose sensing, insulin secretion, and β cell maintenance. GLIS3, a transcription factor involved in pancreatic development as well as the transcriptional regulation of insulin has been identified as a risk locus for type 1 and type 2 diabetes …

A Content Analysis Of Reddit Comments Discussing Fibroadenoma Appraisal And Decision Making, Hayley Marie Kay Stahl

Theses and Dissertations--Communication

Though fibroadenomas are clinically benign in most cases, clinical research suggests that these lesions can cause diagnosis-related physical health complications and psychological distress. However, this research is limited and should be investigated further. Thus, this study aimed to explore how patients appraise their fibroadenoma diagnosis uncertainty. Additionally, this study sought to determine if a correlation existed between appraisal and decision making as well as identify the factors that influence the most common treatment decision: removal. Data was retrieved from Reddit discussions for a content analysis. These discussions were then qualitatively analyzed using codebooks associated with this study’s research questions. Findings …

Liquid Biopsies To Occult Brain Metastasis, Asad Ur Rehman, Parvez Khan, Shailendra K. Maurya, Jawed A. Siddiqui, Juan A. Santamaria-Barria, Surinder K. Batra, Mohd W. Nasser

Journal Articles: Biochemistry & Molecular Biology

Brain metastasis (BrM) is a major problem associated with cancer-related mortality, and currently, no specific biomarkers are available in clinical settings for early detection. Liquid biopsy is widely accepted as a non-invasive method for diagnosing cancer and other diseases. We have reviewed the evidence that shows how the molecular alterations are involved in BrM, majorly from breast cancer (BC), lung cancer (LC), and melanoma, with an inception in how they can be employed for biomarker development. We discussed genetic and epigenetic changes that influence cancer cells to breach the blood-brain barrier (BBB) and help to establish metastatic lesions in the …

Modulation Of Arginase-2 Mrna Levels By Ω-3 Pufas And Aspirin In Asthmatic Human Lung Fibroblasts, Vamsee K Duggirala, Kyla Geary, Donald Hasenmayer, Farzaneh Daghigh

PCOM Scholarly Works

Airway remodeling (AR) increases disease severity, and morbidity of asthmatic patients by contributing to irreversible airflow obstruction and progressive declines in lung function. Arginase isoenzymes and the downstream enzymes ornithine decarboxylase (ODC) and ornithine aminotransferase (OAT) have been implicated in the hyperplastic and fibrotic changes of AR, respectively. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) and resolvin metabolites have anti-AR effects, but whether they are mediated through the arginase pathway is unclear. Our study intended to determine the effects of the ω-3 PUFAs eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), resolvin D1 (RvD1), TH1 cytokines, acetylsalicylic acid (ASA), cAMP, …
