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

Center for Brain, Biology, and Behavior: Faculty 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 outcomes between …

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 engagement in …

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 between …

Lead X-Ray Vests: Pros And Cons In Dental Radiography And Patient Education On Radiographic Technology, Kayla D. Oakley, Emily Deker

Neural Bases Of Phonological And Semantic Processing In Early Childhood, Avantika Mathur, Douglas H. Schultz, Yingying Wang Dr.

Center for Brain, Biology, and Behavior: Faculty Publications

During the early period of reading development, children gain phonological (letter-to-sound mapping) and semantic knowledge (storage and retrieval of word meaning). Their reading ability changes rapidly, accompanied by learning-induced brain plasticity as they learn to read. This study aims at identifying the neural bases of phonological and semantic processing in early childhood by using a combination of univariate and multivariate pattern analysis. Nineteen typically developing children between the age of five and seven performed visual word-level phonological (rhyming) and semantic (related meaning) judgment tasks during functional magnetic resonance imaging scans. Our multivariate analysis showed that young children with good reading …

Development Of A Torque-Based Device For The Quantification Of Arm Rigidity In Patients With Parkinson’S Disease, Georgina O. Miller

Theses and Dissertations

Parkinsonian rigidity is caused by the inability of the muscles to relax and extend properly, due to reduced dopamine levels and often begins on one side of the body before spreading contralaterally. The current standard for determining joint rigidity in a clinical setting is a test completed by the clinician based on the feel of the relaxed wrist and elbow joints as they are passively flexed and extended and a series of ordinal rating scales, the Movement Disorder Society’s – Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr Scale (H&Y), and Parkinson’s Disease Questionnaire-39 (PDQ-39). These methods are used …

The Positive Effects Of Exercise On Active Transplant Recipients And Its Impact On Medication Adherence, Travane Morrison

Theses

Organ failure is a life-threatening condition (Daugirdas et al, 2014). Non-adherence to medication is one of the main causes of the failure of a transplanted organ (Oberlin et al, 2016). In an effort to combat non-adherence to medication, research had employed intervention studies to tackle the main cause of non-adherence (Chisholm-Burns, 2013). The aims of this project are three fold. Firstly it aims to find if complications associated with organ transplant affect the individual’s medication adherence. Secondly, it explores the connections between exercise and medication adherence. Thirdly the research explores if exercise assists with possible complications associated with an organ …

Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

The Efficacy Of Acute Normovolemic Hemodilution Compared To Cell Salvage As A Blood Transfusion Alternative, Julia Yu

Capstone Showcase

Blood transfusions are currently the treatment of choice for significant blood loss. However, there are a variety of reasons for which they cannot be utilized. Current alternatives are acute normovolemic hemodilution (ANH) and cell 1 This study analyzes whether ANH or cell salvage is more effective in minimizing blood loss in perioperative or trauma patients. Multiple different studies involving either ANH or cell salvage were compared to each other. However, due to the lack of research conducted in either method, results obtained were largely inconclusive.

Adaptive Background Correction Of Crystal Image Datasets: Towards Automated Process Control, Luke Kiernan, Ian Jones, Lauri Kurki, Patrick J. Cullen, Toufic El Arnaout

Articles

Improving the data descriptor calculation of crystal’s physical properties requires sophisticated imaging techniques and algorithms. It has been possible to construct 2D population balance models benefiting from characteristic measurements of both crystal’s length and width, compared to the single representative sizes used in 1D models. Our aim is to ameliorate the procedure of determining shape (and not only size) factors, in an automated fashion and directly from the process, for implementation in future models. Here, approaches suitable for real-time applications were employed including engineered imaging sensors and adaptive algorithms. We described the latter in detail for varying 2D image datasets. …
