Carbon Dots As Artificial Peroxidases For Analytical Applications, Shih-Chun Wei, Yang-Wei Lin, Huan-Tsung Chang

Journal of Food and Drug Analysis

Nanozymes have become attractive in analytical and biomedical fields, mainly because of their low cost, long shelf life, and less environmental sensitivity. Particularly, nanozymes formed from nanomaterials having high surface area and rich active sites are interesting since their activities can be tuned through carefully controlling their size, morphology, and surface properties. This review article focuses on preparation of carbon dots (C dots) possessing peroxidase-like activity and their analytical applications. We highlight the important roles of the oxidation states and surface residues of C dots and their nanocomposites with metal, metal oxides, or metal sulfides playing on determining their specificity …

Using Preliminary Data And Prospective Power Analyses For Mid-Stream Revision Of Projected Group And Subgroup Sizes In Pragmatic Patient-Centered Outcomes Research, Elizabeth A. Tolley Md, Satya Surbhi Md, James E. Bailey Md

Faculty Publications and Presentations

Pragmatic clinical trials are commonly used in patient-centered outcomes research to assess heterogeneity of treatment effects. Patient-Centered Outcomes Research Institute (PCORI) methodology standards for assessing heterogeneity of treatment effects are extremely rigorous, but their implementation in real-world settings can be difficult. Predicting recruitment effectiveness and subgroup characteristics is often challenging and may require mid-stream revision of projected group and subgroup sizes. Yet, little real-world data are available to demonstrate methodologically valid approaches to address situations where such revisions are necessary. These data were used for mid-stream revision of group and subgroup sizes in the Management of Diabetes in Everyday Life …

Differential Diagnosis Of Exercise-Induced Laryngeal Obstruction And Exercise-Induced Asthma, Allison Lyman, Allison Lyman

Honors College Theses

Sensations of shortness of breath and difficulty breathing are not uncommon, especially among athletes and those who regularly engage in aerobic activities. Often, athletes will seek treatment for their respiratory symptoms and may be diagnosed with exercise-induced asthma. Doctors prescribe inhalers to these individuals to help alleviate their symptoms; however, there are occasions in which inhalers fail to lessen the severity of breathing difficulties. This is because asthma is not the only condition that can cause shortness of breath, also known as dyspnea. There exists another condition which affects the vocal folds but not the lungs and bronchioles as is …

Evaluation Of An Intervention To Maintain Therapeutic Pressure Of The Endotracheal Tube Cuff During Intraoperative Surgery, Jamare Reed

Doctoral Projects

The current practice of intraoperatively assessing the cuff pressure of the endotracheal tube (ETT) is arbitrary and potentially leads to negative impacts on patients. This best practice project aimed to review and synthesize the existing evidence-based literature on measuring ETT cuff pressure and to establish a policy guideline for anesthesia providers to measure ETT cuff pressure in the intraoperative environment. Based on the star model of the knowledge transformation framework model provided by the Academic Center for Evidence-Based Practice (ACE), the creation of evidence-based policy on ETT cuff measurement is expected to potentially prevent poor patient outcomes, patient expenses, and …

Early Diagnosis Of Alzheimer’S Disease In The Primary Care Setting, Raymond R. Romano

Theses and Dissertations (ETD)

The burden of Alzheimer’s disease (AD) affects not just the individual but also families, providers, and society. Early recognition and diagnosis of AD may reduce cost by reducing interaction with the health care system, earlier initiation of treatment, and prolonging time to long- term care. Primary care providers, the first contact for diagnosis of patients with AD, are not fulfilling the potential of early diagnosis for a variety of reasons. Biomarkers of AD emerge on average 15 to 20 years before clinical diagnosis, yet currently established biomarkers are not easily available in the primary care setting. A growing body of …

Extra Axial Chordoma Of The Distal Femoral Metaphysis: A Case Report, Long Nguyen, Irene Vasko, Gord G. Zhu, Veniamin Barshay

Cooper Rowan Medical Journal

Background

Chordomas are malignant bone tumors that are derived from remnant embryonic tissue of the notochord and are typically found in the axial midline. When they are found outside of the axial skeleton, the diagnosis can be challenging and elusive. Often, they are overlooked on initial presentation in lieu of other more common lesions, including cartilage tumors (eg, enchondroma, chondrosarcoma, osteochondromatosis) due to their overlapping features.

Case Report

A 30-year-old female with a four-year history of intermittent left knee pain presented for initial evaluation. Physical exam of the knee was unremarkable except for moderate tenderness on palpation. Radiographs showed a …

Mental Health And Its Wicked Factors, Michael Schuler

English Department: Research for Change - Wicked Problems in Our World

Mental health has long since been an issue in not just our society, but worldwide. While it is difficult to determine exactly what factors affect mental health, there has been significant research done within the past 30 years to show that major factors that affect mental health can be mitigated. Things such as poverty, physical health, and community outreach can all be linked to mental health issues. There are some solutions that will mitigate these factors that can be explored. These solutions can include things like raising awareness for mental illnesses in order to reduce stigma, getting more mental health …

State Transition Modeling Of Complex Monitored Health Data, Jörn Schulz, Jan Terje Kvaløy, Kjersti Engan, Trygve Eftestol, Samwel Jatosh, Hussein Kidanto, Hege Ersdal

Faculty of Health Sciences, East Africa

This article considers the analysis of complex monitored health data, where often one or several signals are reflecting the current health status that can be represented by a finite number of states, in addition to a set of covariates. In particular, we consider a novel application of a non-parametric state intensity regression method in order to study time-dependent effects of covariates on the state transition intensities. The method can handle baseline, time varying as well as dynamic covariates. Because of the non-parametric nature, the method can handle different data types and challenges under minimal assumptions. If the signal that is …

Audiovisual Integration During Novel Word Learning Among School-Aged Children With Cochlear Implants, Kristen Elizabeth Thompson Thornton

Theses and Dissertations (ETD)

Objective. It is well established that being able to see someone’s mouth move as they speak boosts speech perception for children with cochlear implants (CIs). Thus, children with CIs are often instructed to orient themselves toward the person they are listening to, to gain access to visual speech cues. Children with CIs who are better “audiovisual integrators,” or those who experience an auditory-visual (AV) enhancement effect (higher performance for AV information than auditory-alone (AO) or visual-alone (VO)), are more likely to have better speech and language outcomes after receiving their CI than children with poorer AV integration skills. While AV …

Methods: Patients with type 2 diabetes mellitus were included and classified into varying degrees of DR based on presence and severity. Flicker ERG responses were recorded and compared between groups.

Results: Between the varying disease stages, significant differences in the mean magnitude and phase values were found. There was also a significant difference between the proportions of the magnitude and phase color-coded frequencies between groups of severity and threat to …

Predictors Of Birth Center Sustainability In The United States, Melanie Cabezas Phipps

Nursing ETDs

Pregnant women from all racial and socioeconomic communities deserve safe, personalized, and affordable ways to give birth. To meet all three needs, focus is increasing on birth centers, a midwifery model that provides family-centered care before, during, and after normal pregnancy, labor, and birth. However, many U.S. birth centers face significant obstacles to financial sustainability, particularly in rural areas. A better understanding of the factors that contribute to a birth center’s operational success is needed for practitioners and groups interested in establishing or maintaining a birth center, as well as to inform policymakers seeking to improve health care equity, outcomes, …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Journal of Patient-Centered Research and Reviews

Purpose: This study aimed to assess the optimal tumor diameter for predicting lymphatic metastasis and to determine intraoperatively the need for lymph node dissection in patients with endometrioid endometrial cancer.

Methods: Military beneficiaries diagnosed with stage I–III endometrioid endometrial cancer during 2003–2016 who had at least 7 pelvic and/or paraaortic lymph nodes removed during the time of hysterectomy were studied. Tumor diameter was compared against the presence of positive nodes, using the prior models of 20 mm (ie, Mayo model) and 50 mm (ie, Milwaukee model), to determine the false-negative rate of each threshold. A separate analysis was completed to …

Anesthetic Use In Status Epilepticus: A Concise Review, Furkan M. Yilmaz, Lauren A. Igneri, Yasir A. Yilmaz, Evren Burakgazi-Dalkilic

Cooper Rowan Medical Journal

The purpose of this review is to summarize the recent literature focusing on intravenous (IV) administration of commonly used anesthetics, including midazolam, pentobarbital/ thiopental, propofol, and ketamine in the treatment of status epilepticus (SE). Anesthetics should be reserved as third-line therapy for the treatment of SE when benzodiazepines and other second-line agents fail to terminate the seizure. We have reviewed the literature related to the treatment of status epilepticus, refractory status epilepticus, super-refractory status epilepticus, anesthetics, midazolam, pentobarbital/thiopental, propofol, and ketamine. This paper focuses on the pharmacology, dosages, major side effects, and clinical use of IV anesthetics in the treatment …

Cole Relaxation Frequency As A Prognostic Parameter For Breast Cancer, William D. Gregory, Shahila Mehboob Christie, John Shell, Georges J. Nahhas, Maharaj Singh, Wendy Mikkelson

Journal of Patient-Centered Research and Reviews

We previously reported successful classification of breast cancer versus benign tissue using the Cole relaxation frequency measured on tissue excised during breast surgery as part of a study at two urban hospitals in the U.S. Midwest. Using that health system’s cancer registry, we have discovered retrospectively that outcomes for patients who participated in the initial study can be classified correctly in 3 well-differentiated categories: nonrecurrent (NR); recurrent with no metastasis (RNM); and recurrent with metastasis (RM). As Cole relaxation frequency increases, the classification moves from NR to RNM and finally to RM. Multivariate analysis showed a significant association of “time-cancer-free” …

Characterization Of The 5′-Flanking Region Of The Human And Mouse Chac1 Genes, Yuki Nomura, Charity F. Sylvester, Lisa O. Nguyen, Mahmoud Kandeel, Yoko Hirata, Imran N. Mungrue, Kentaro Oh-Hashi

School of Medicine Faculty Publications

The Unfolded Protein Response pathway is a conserved signaling mechanism having important roles in cellular physiology and is perturbed accompanying disease. We previously identified the novel UPR target gene CHAC1, a direct target of ATF4, downstream of PERK-EIF2A and activated by the UPR pathway. CHAC1 enzyme directs catalysis of γ-linked glutamate bonds within specific molecular targets. CHAC1 is the first enzyme characterized that can catalyze intracellular glutathione degradation in eukaryotes, having implications for regulation of oxidative stress. DDIT3 (CHOP) is a terminal UPR transcription factor, regulated by ATF4 and an output promoting cell death signaling. Herein we examine the relationship …

3d Reconstruction Of Spine Image From 2d Mri Slices Along One Axis, Somoballi Ghoshal, Sourav Banu, Amlan Chakrabarti, Susmita Sur-Kolay, Alok Pandit

Journal Articles

Magnetic resonance imaging (MRI) is a very effective method for identifying any abnormality in the structure and physiology of the spine. However, MRI is time consuming as well as costly. In this work, the authors propose an algorithm which can reduce the time of MRI and thus the cost, with minimal compromise on accuracy. They reconstruct a three-dimensional (3D) image of the spine from a sequence of 2D MRI slices along any one axis with reasonable slice gap. In order to preserve the image at the edges properly, they regenerate the 3D image by using a combination of bicubic and …

Transcutaneous Energy Transmission: Can We Do It Now?, Yuriy Pya

The VAD Journal

The percutaneous driveline used in contemporary LVADs presents a continuous risk of infection for the duration of support. Minimizing infection in durable mechanical circulatory support systems requires total implantation of all components and energy transfer by means other than percutaneous drivelines. A novel coplanar energy transfer (CET) system, similar to the original transcutaneous energy transfer (TET) design, is unique by incorporating two large rings with coil-within-the-coil topology to ensure strong resonance power. The CET system consists of an internal integrated controller, a battery coupled with an internal thoracic coil ring, and the LVAD pump. External equipment includes a power transmission …
