Pharmacy Faculty Articles and Research

Objectives:

Sepsis is a leading cause of death in the United States. Putative targets to prevent systemic inflammatory response syndrome include antagonism of toll-like receptors 2 and 4 and CD44 receptors in vascular endothelial cells. Proteoglycan-4 is a mucinous glycoprotein that interacts with CD44 and toll-like receptor 4 resulting in a blockade of the NOD-like receptor pyrin domain-containing-3 pathway. We hypothesized that endothelial cells induced into a sepsis phenotype would have less interleukin-6 expression after recombinant human proteoglycan 4 treatment in vitro.

Design:

Enzyme-linked immunosorbent assay and reverse transcriptase-quantitative polymerase chain reaction to measure interleukin-6 protein and gene expression.

Alexithymia Symptoms Are Not Associated With Childhood Trauma Or Crhr1 Rs110402 Genotype, Emily Wiatr, Grace Sullivan, Scott Stoltenberg

Center for Brain, Biology and Behavior: Papers & Publications

Alexithymia is associated with difficulties in emotional self-regulation, and alexithymia is specifically associated with an absence of emotional experience and cognition of emotion. Past research has indicated a potential association between alexithymia and the CRHR1 gene . Situational factors may also impact the expression of the CRHR1 gene within an individual. Berenbaum (1996) found associations between PTSD/childhood trauma and alexithymia. This study examined these associations using the Online Alexithymia Questionnaire-G2 (OAQ-G2) as well as DNA samples gathered from 657 participants at the University of Nebraska-Lincoln (72% women; 78.6% white; mean age= 20.34; standard deviation of 2.6).

Single Vs. Multiple Laparoscopies: Pain Status One Year Post-Hysterectomy For Chronic Pelvic Pain, Ghadear Shukr, Madeleine R. Gonte, Victoria Webber, David Eisenstein

Medical Student Research Symposium

Despite the prevalence of chronic pelvic pain (CPP)— affecting one in seven women in the U.S.— its cause is often unknown. As such, an evaluation of our current approaches to the work-up of CPP is warranted. Laparoscopy is considered a gold standard tool in the evaluation of CPP with 40% of all laparoscopies in the U.S. performed for this condition [1]. However, limited data exists portraying the clinical importance and outcomes for repeat diagnostic laparoscopies. This is a retrospective case-control study to determine the incidence of multiple laparoscopies for CPP over the past 10 years, and to compare ...

Us Guided Management Of Undifferentiated Dyspneic Patient In The Ed, Kaleigh Miller

Longitudinal Scholar's Project

Intro: Undifferentiated dyspnea can be a complicated presentation muddled by patient comorbidities and similar symptomology shared among etiologies. Some studies have shown increased mortality and length of stay in the hospital when incorrectly initially diagnosed in the ED. US has been shown more effective at differentiating these causes and improves diagnostic accuracy. This study will implement US exam upon initial exam of patient and chart time to diagnosis/treatment, length of stay in ED, length of stay in hospital admissions versus discharge rates, and 30 day mortality. ADHF and COPD/asthma patient differentiation will be the focus. Methods: Prospective cohort ...


Machine Learning Towards General Medical Image Segmentation, Clara Tam 2020 The University of Western Ontario

Machine Learning Towards General Medical Image Segmentation, Clara Tam

Electronic Thesis and Dissertation Repository

The quality of patient care associated with diagnostic radiology is proportionate to a physician's workload. Segmentation is a fundamental limiting precursor to diagnostic and therapeutic procedures. Advances in machine learning aims to increase diagnostic efficiency to replace single applications with generalized algorithms. We approached segmentation as a multitask shape regression problem, simultaneously predicting coordinates on an object's contour while jointly capturing global shape information. Shape regression models inherent point correlations to recover ambiguous boundaries not supported by clear edges and region homogeneity. Its capabilities was investigated using multi-output support vector regression (MSVR) on head and neck (HaN) CT ...

From Their Perspective: A Qualitative Analysis Of Stroke Survivor’S Motivation To Participate In Rehabilitation, Katie Tinsley, Rachel Johnson

Undergraduate Research Symposium

Introduction: It is common practice for healthcare professionals to make judgments about a patient's motivation based on their demeanor and compliance with therapy. Motivation is one of the predictors used to determine a stroke survivor's rehabilitation potential. There are several theories and constructs for motivation; however, there is limited research applying these concepts in stroke rehabilitation. Rehabilitation clinicians primarily rely on their clinical judgment and consult the evidence from related fields to identify the motivational needs of a stroke survivor. The objective of this study was to understand specific barriers to participation and identify motivational needs to sustain ...

Listening To The Patient: A Typology Of Contextual Red Flags In Disease Management Encounters, Amy E. Binns-Calvey, Gunjan Sharma, Naomi Ashley, Brendan Kelly, Frances M. Weaver, Saul J. Weiner

Journal of Patient-Centered Research and Reviews

Purpose: Patients send clues, often unwittingly, when they are grappling with a life challenge that complicates their care. For instance, a patient may lose control of a previously well-managed chronic condition or start missing appointments. When explored, these clues help clinicians uncover the life circumstance impacting the individual’s ability to manage their health and health care. Such clues are termed “contextual red flags.” Effective care requires recognizing them, asking about them, and customizing the care plan where feasible. We sought to develop a typology of contextual red flags by analyzing audio recordings along with the medical records of encounters ...
