Regression Discontinuity Designs Within A Latent Variable Framework: Measurement Considerations For The Accuracy Of The Treatment Effect, Sarah Hammami 2024 University of Nebraska-Lincoln

Regression Discontinuity Designs Within A Latent Variable Framework: Measurement Considerations For The Accuracy Of The Treatment Effect, Sarah Hammami

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs are valuable quasi-experimental designs, especially when randomized control/clinical trials are ethically or practically challenging. Latent variables are prevalent in the social, behavioral, and educational (SBE) sciences—measurement assumptions have to be tested and met when using such variables. Not meeting those assumptions leads to biased results and (likely) erroneous inferential making. One way to minimize the impact of measurement assumption violation is to use latent variable modeling such as structural equation modeling (SEM). Soland, Johnson and Talbert (2022) conducted two simulation studies testing the effect of using a sum score (when the assumptions for using such a score …


A Meta-Analysis For Laboratory Diagnostics For Coccidioidomycosis, Mary C. Cowen 2024 University of Arkansas, Fayetteville

A Meta-Analysis For Laboratory Diagnostics For Coccidioidomycosis, Mary C. Cowen

Biological Sciences Undergraduate Honors Theses

Coccidioidomycosis, commonly referred to as Valley Fever, is a fungal infection found in arid regions of the southwestern United States and Mexico. Infection occurs through inhalation of airborne spores from Coccidioides species, Coccidioides immitis and/or Coccidioides posadasii, and proceeds in both pulmonary and disseminated fashions. Approximately 60% of patients with coccidioidomycosis remain asymptomatic, while 40% will experience symptoms. Within the literature, there are no papers that summarize sensitivity and specificity values between different tests; therefore, this paper presents sensitivity and specificity results across different tests and companies (Meridian, IMMY, and MiraVista).


Exploring The Neuroprotective Effects Of Cannabinoids On Oxygen Glucose Deprived Neurons In An In-Vitro Model Of Stroke, Bhavya Chatragadda, Emily Potts, Hang Ma, Navindra Seeram, Claudia Fallini 2024 University of Rhode Island

Exploring The Neuroprotective Effects Of Cannabinoids On Oxygen Glucose Deprived Neurons In An In-Vitro Model Of Stroke, Bhavya Chatragadda, Emily Potts, Hang Ma, Navindra Seeram, Claudia Fallini

Senior Honors Projects

Stroke is a leading cause of long-term disability and decreased mobility worldwide. During stroke, neuronal damage results from both the initial oxygen-glucose deprivation and the increase in excitotoxicity and oxidative stress after restoration of blood flow, a phase called Ischemia-Reperfusion Injury (IRI). Reducing the impact of these processes could result in better outcomes for post-stroke patients by preventing excessive neuronal death. Many natural compounds derived from the Cannabis Sativa plant have been tested for neuroprotective effects due to their potential antioxidant properties. We hypothesized that neurons treated with cannabinoids immediately after experiencing an acute ischemic event will have an overall …

We present this study to predict the probability of an occult fracture using radiographic soft-tissue swelling on initial ED radiographs. METHODS: This is a retrospective study at a Level 1 pediatric trauma center from 2021 to 22. Soft-tissue swelling between the lateral malleolus and skin was measured on radiographs, and weight-bearing status was documented. Statistical analysis was conducted using Stata software. DISCUSSION: The …


Inclusion Of Adoption As A Pregnancy Management Option In Prenatal Genetic Counseling Practice, Emma Billings 2024 The Texas Medical Center Library

Inclusion Of Adoption As A Pregnancy Management Option In Prenatal Genetic Counseling Practice, Emma Billings

Dissertations and Theses (Open Access)

Prenatal genetic counselors are essential to providing education, psychosocial support, and guidance on pregnancy options to patients who receive a fetal diagnosis of an anomaly or genetic condition. Therefore, genetic counselors should be well-educated on comprehensive pregnancy management options consisting of parenting, abortion, and adoption. The landscape of adoption education in genetic counseling practice was last characterized in 2010 by Perry and Henry, revealing substantial variability in both the inclusion of adoption-specific education in genetic counseling program (GCP) curricula and the discussion of pregnancy options with patients in prenatal practice. As a result, the authors published a call to action …

The growing body of evidence linking residual neuromuscular blockade (NMB) to postoperative complications has underscored the need to integrate quantitative neuromuscular monitoring techniques into anesthesia practice. This study, conducted at a tertiary care center in southern Illinois, investigates the gap between current clinical practices and the latest evidence advocating for objective monitoring. The study utilized a non-experimental pretest-posttest design to evaluate an educational intervention's effectiveness in increasing anesthesia providers' knowledge of quantitative neuromuscular monitoring techniques and enhancing their awareness of the incidence and clinical implications of postoperative residual neuromuscular blockade. Analysis of the pretest and post-test responses revealed significant improvements …


Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey 2024 Clemson University

Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey

All Theses

Bovine in-vitro production(IVP) of embryos is a growing field for producing offspring with desirable genetics in the cattle industries. While IVP is effective, oocyte cytoplasmic maturation is compromised, and bovine oocytes matured in-vitro have reduced metabolic activity than those matured in-vivo. Mitochondria are the central unit of oocyte metabolism, producing ATP through OXPHOS. Photobiomodulation is a light treatment reported to improve metabolic activity. In five experiments, we measured the effects of photobiomodulation treatment with red LED at 16-(L-16) and 20 h(L-20) of bovine oocyte in-vitro maturation on subsequent embryonic development, mitochondrial activity and nuclear progression. Bovine COCs were aspirated …

The Case For Using Composition Tomography To Evaluate Perirectal Necrotizing Fasciitis: Is It Really Necessary?, Tyler Bayliss, David Denning

Marshall Journal of Medicine

Clinical reviews of Fournier’s Gangrene state that diagnostic protocol includes interpreting CT, MRI, or Ultrasound imaging along with clinical symptoms and lab findings. We think that the use of imaging techniques as a diagnostic tool is no longer needed as Fournier’s Gangrene is specific enough of a disease that clinicians can diagnose using labs and physical examination alone.

Cases of perirectal necrotizing soft tissue infection recorded at St. Marys Medical Center were reviewed. Results of physical exams and imaging were compared along with measurements of severity upon admittance and length of stay. Due to the COVID-19 pandemic, we investigated if …

Decorin Suppresses Tumor Lymphangiogenesis: A Mechanism To Curtail Cancer Progression, Dipon K. Mondal, Christopher Xie, Gabriel J. Pascal, Simone Buraschi, Renato V. Iozzo

Kimmel Cancer Center Faculty Papers

The complex interplay between malignant cells and the cellular and molecular components of the tumor stroma is a key aspect of cancer growth and development. These tumor-host interactions are often affected by soluble bioactive molecules such as proteoglycans. Decorin, an archetypical small leucine-rich proteoglycan primarily expressed by stromal cells, affects cancer growth in its soluble form by interacting with several receptor tyrosine kinases (RTK). Overall, decorin leads to a context-dependent and protracted cessation of oncogenic RTK activity by attenuating their ability to drive a prosurvival program and to sustain a proangiogenic network. Through an unbiased transcriptomic analysis using deep RNAseq, …

Outcomes Of Drug-Eluting Stents In Comparison To Bare Metal Stents In Cancer Patients With Percutaneous Coronary Intervention: A Systematic Review And Meta-Analysis, Muhammad Siddiqui, Eric Warner, Joey Junarta, Parker O’Neill, David Signarovitz, Eyad Kanawati, Mohammed Murtaza, David Fischman

Division of Cardiology Faculty Papers

Background: Studies have demonstrated poor prognosis in cancer patients who undergo percutaneous coronary intervention (PCI) for coronary artery disease (CAD). Cancer patients receiving PCI are at increased risk of in-stent thrombosis, bleeding, hospital readmissions, and cardiovascular and noncardiovascular mortality when compared to patients without cancer. It is unclear if the poor outcomes in cancer patients are related to the stent type utilized for PCI. This meta-analysis attempts to identify differences in efficacy and safety outcomes when comparing drug-eluting stents (DESs) with bare metal stents (BMSs) in cancer patients.

Methods: This meta-analysis is reported according to the Preferred Reporting Items for …

Such an understanding can influence both operative and nonoperative decision-making and implant choices. This study evaluated 5-year mortality following shoulder arthroplasty in patients ≥65 years old and identified associated risk factors.

METHODS: We utilized Centers for Medicare & Medicaid Services Fee-for-Service inpatient and outpatient claims data to investigate the 5-year mortality rate following shoulder arthroplasty procedures performed from 2014 to 2016. The impact of patient demographics, including fracture …


Development And Implementation Of An Evidence Based Practice Guideline Related To The Management Of Adult Angioedema, Megan Przybysz 2024 Otterbein University

Development And Implementation Of An Evidence Based Practice Guideline Related To The Management Of Adult Angioedema, Megan Przybysz

Doctor of Nursing Practice Scholarly Projects

Angioedema (AE) is a potentially life-threatening medical condition that occurs with a higher frequency than medical providers may expect, with the emergency department (ED) serving as the usual first point of medical contact for patients. Any hesitation in recognizing AE or inconsideration of the disease process in differential diagnoses may lead to a dangerous delay of care. Due to the potential rapid progression of airway obstruction in AE, inexperienced providers should not attempt intubation, instead deferring to providers experienced in alternative airway techniques (i.e., anesthesia providers). The primary goal of this project is to develop an evidencebased practice guideline for …

Doctor of Nursing Practice Projects

Purpose/Background

The need for effective pharmacological management in patients with congestive heart failure (CHF) and type II diabetes mellitus (T2DM) is an ever-growing task for healthcare providers, especially in the primary care setting. Patients with multiple comorbidities are less likely to adhere to required rigorous medication schedules and lifestyle modifications, resulting in accelerated disease progression and defeated efforts of healthcare providers. Traditionally, sulfonylureas have been the medication management of choice by healthcare providers due to their affordability compared to modern medication. Current guidelines recommend that individuals with poor glycemic control could benefit significantly from using older sulfonylureas with other antidiabetic …

Decreasing Re-Intubation Rates in Mechanically Ventilated Adult Patients: A Scoping Review

Purpose/Background

Critically ill patients often require mechanical ventilation to support respiratory function. Prolonging mechanical ventilation can increase adverse outcomes. Weaning patients from the ventilator as soon as clinically appropriate can decrease adverse outcomes. The decision to wean mechanical ventilation lacks a standardized approach. This scoping review will evaluate the literature about the effectiveness of a standardized weaning protocol in decreasing the number of reintubations within 72 hours of extubation.

Methods

We conducted a literature search on PubMed, CINAHL, Scopus, and Medline between November 2020 and November 2023 using key …
