Burnout With Caregiving Of Autism And The Covid19 Pandemic, Erin Babcock, Leah Recker
Williams Honors College, Honors Research Projects
I am working with Leah Recker and we are doing research on parent/caregiver burnout of those with children that have autism, especially during COVID. We are creating a survey on Qualtrics, using stem questions followed by Likert scale items, which we will then send to the Director of Programs, Lisa Thompson, at Autism Society of Greater Akron. She will then pass it along to the parents and caregivers within their community, via Facebook or their weekly newsletter. Parents/caregivers will have the opportunity to complete the survey and we will receive the results when done so. We will then analyze the …
Neurally Adjusted Ventilatory Assist: Summation Of The Safety Proofs And Benefits, Landry Carneal
Neurally Adjusted Ventilatory Assist: Summation Of The Safety Proofs And Benefits, Landry Carneal
Williams Honors College, Honors Research Projects
Neurally Adjusted Ventilatory Assist (NAVA) is a mode of ventilation that is triggered by neither flow nor pressure but by the electrical activity of the diaphragm (Stein & Firestone, 2018, p. 227). NAVA puts ventilatory control into the hands of the patient and is often used in neonates who are more challenging to ventilate. Medical practitioners, however, are skeptical to put this mode of ventilation into practice with fear that neonates are neither strong enough nor capable to manage their own respiratory efforts without hypoventilation or damage to the lungs (Lubarsky et al., 2020, p. 3). Research shows that despite …

Department of Medicine Faculty Papers
Background
Apixaban pharmacokinetic properties and some clinical reports suggest cessation 48 hours prior to surgery is safe, but this has not been demonstrated in a naturalistic setting. We sought to measure the residual apixaban exposure in patients who had apixaban held as part of standard of care peri-operative management.
Methods
This was a prospective, observational study of patients in whom apixaban plasma concentration and anti-Xa activity were measured while at steady state apixaban dosing and again immediately prior to surgery. Clinical management of cessation and resumption of apixaban was at the discretion of the treating physician.
Results
One hundred and …
Therapeutic Targeting Of Leukemia Stem Cells To Prevent T-Cell Acute Lymphoblastic Leukemia Relapse, Meghan G. Haney
Therapeutic Targeting Of Leukemia Stem Cells To Prevent T-Cell Acute Lymphoblastic Leukemia Relapse, Meghan G. Haney
Theses and Dissertations--Molecular and Cellular Biochemistry
The survival rate of T-cell Acute Lymphoblastic Leukemia (T-ALL) relapse is a dismal 10% of affected adults and 30% of children, largely due to the relapsed disease being more aggressive and treatment resistant than the initial disease. Relapse is thought to occur because conventional chemotherapies are unable to reliably eliminate a unique cell type known as leukemia stem (or propagating) cells (LSCs). LSCs are the only cells within the leukemia with the ability to self-renew and remake or replenish the ALL from a single cell. Currently, the pathways governing self-renewal in LSCs are largely unknown, precluding our ability to successfully …
Evaluating The Clinical Utility Of A Novel Electroencephalography System For Assessing Perioperative Neurocognition In Older Surgical Patients, Lloyd H. Barnwell Iii
Evaluating The Clinical Utility Of A Novel Electroencephalography System For Assessing Perioperative Neurocognition In Older Surgical Patients, Lloyd H. Barnwell Iii
Theses and Dissertations
Postoperative delirium (POD) is a public health and research priority (American Society of Anesthesiologists, 2019). POD is a risk factor for long-term neurocognitive decline, and the rate of decline is directly proportional to the severity of POD (Vasunilashorn et al., 2018). Baseline cognitive function is a strong, independent predictor for POD (Culley et al., 2017). The International Perioperative Neurotoxicity Working Group recommends baseline cognitive function be assessed for older patients prior to surgery and anesthesia (Berger, et al., 2018). Perioperative cognitive screening tools trialed in anesthesia are not routinely incorporated into clinical practice related to validity, reliability, or practicality problems …

Research outputs 2014 to 2021
Vitamin D has many effects on cells in the immune system. Many studies have linked low vitamin D status with severity of COVID-19. Genetic variants involved in vitamin D metabolism have been implicated as potential risk factors for severe COVID-19 outcomes. This study investigated how genetic variations in humans affected the clinical presentation of COVID-19. In total, 646 patients with SARS-CoV-2 infection were divided into two groups: noncritical COVID-19 (n = 453; 70.12%) and a critical group (n = 193; 29.87%). Genotype data on the GC, NADSYN1, VDR, and CYP2R1 genes along with data on serum 25-hydroxyvitamin D levels were …

Background: Current literature lacks characterization of the post-recovery sequelae among COVID-19 patients. This review characterizes the course of clinical, laboratory, radiological findings during the primary infection period, and the complications post-recovery. Primary care findings are presented for long-COVID care.
Methods: Adhering to PRISMA guidelines, 4 databases were searched (PubMed, Embase, CINAHL Plus, Scopus) through December 5, 2020, using the keywords "COVID-19 and/or recovered and/or cardiovascular and/or long-term and/or sequelae and/or sub-acute and/or complication." We included published peer-reviewed case reports, case series, and cross-sectional studies providing the clinical course of COVID-19 infection, and cardiopulmonary complications of patients who recovered from COVID-19, …
Anterior Cruciate Ligament Injury Incidence Across Sex, Sport, And Level: A Systematic Review And Meta-Analysis, Dana Anderson
Anterior Cruciate Ligament Injury Incidence Across Sex, Sport, And Level: A Systematic Review And Meta-Analysis, Dana Anderson
Dissertations, Master's Theses and Master's Reports
Well controlled Anterior Cruciate Ligament (ACL) injury prevention neuromuscular training reduces the risk of ACL injury by 50%, but despite the efficacy of these programs, ACL injury rates have not decreased. This lack of decrease in injury incidence may be due in part to limited knowledge on who is most at risk for sustaining an ACL injury, and there is no formal clinical tool available to estimate the personalized or group risk of ACL injury. The purpose of this study was to better understand what groups of athletes are most at risk of sustaining a primary ACL injury, as the …

Augmented Reality In Clinical Dental Training And Education, Zainab Haji, Aysha Arif, Shizrah Jamal, Rabia Ghafoor
Section of Dental-Oral Maxillofacial Surgery
Dentistry is a profession that requires coordinated motor skills in addition to acquired knowledge for ideal execution of any treatment plan for patients. Learning experiences have been modified over a period of time for students as well as for the healthcare providers. Conventional pre-clinical training employed the use of cadavers, but financial, ethical and supervisory constraints have become a major shortcoming. With the adaptation of technology in dentistry, pre-clinical training has now employed simulation. It provides the opportunity for students to develop psychomotor skills for procedures by practising pre-clinical, standardised learning competencies before they engage in patient-management. Simulation involves computer-aided …

Thinking Outside Malaria: A Rare Case Of Disseminated Cysticercosis With Cardiopulmonary Involvement From Urban Tanzania, Frederick R. Lyimo, Ahmed Jusabani, Hilda Makungu, Maria Mtolera, Salim Surani
Imaging & Diagnostic Radiology, East Africa
Dissemination of the cysticerci throughout the body with cardiopulmonary involvement represents a very rare occurrence and an uncommon form of cysticercosis manifestation. We report a rare case of a 48-yearold African male from urban Tanzania who was, at first, referred to our radiology department for a coronary computed tomography angiography (CCTA), but incidentally on further evaluation of the patient revealed a history of recurrent convulsions, loss of consciousness, a single episode of temporary loss of vision and recent skin nodules. The value of a full clinical and radiological evaluation of the patient presenting with adult-onset seizures cannot be overemphasized for …
Is There A Role For Ct Pan-Scans In The Initial Work-Up Of Fragility Fracture Patients?, Eric Lepkowsky, Trevor Simcox, Hunter Rogoff, Shahidul Islam, Omid Barzideh
Is There A Role For Ct Pan-Scans In The Initial Work-Up Of Fragility Fracture Patients?, Eric Lepkowsky, Trevor Simcox, Hunter Rogoff, Shahidul Islam, Omid Barzideh
Stony Brook Orthopaedic and Musculoskeletal Journal
Background: CT pan-scans have become increasingly commonplace as part of the initial diagnostic work-up for patients sustaining traumatic injuries. They have proven effective in improving diagnostic accuracy in those with high energy mechanisms of injury. However, the utility of pan-scans in the geriatric population sustaining low energy traumatic injuries remains unproven. There is no study that assesses the usefulness of CT pan-scans in patients who sustain injuries related to osteoporosis, also known as fragility fractures.
Methods: A retrospective review was conducted of patients who sustained a fragility fracture at a Level 1 trauma center over a 15-month period. Patients underwent …

Nebraska Center for Virology: Faculty Publications
Objective: Significant morbidity and mortality have occurred in the USA, Europe, and Asia due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), whereas the numbers of infections and deaths in sub-Saharan Africa (SSA) have remained comparatively low. It has been hypothesized that exposure of the population in SSA to other coronaviruses prior to the COVID-19 pandemic resulted in some degree of cross-protection against SARS-CoV-2 infection and pathogenesis. We evaluated this hypothesis by comparing SARS-CoV-2 cross-reactive antibodies in pre-pandemic plasma samples collected from SSA and the USA.
Method: Pre-COVID-19 pandemic plasma samples from SSA and the USA were collected and tested by …

Chlorovirus Pbcv-1 Multidomain Protein A111/114r Has Three Glycosyltransferase Functions Involved In The Synthesis Of Atypical N-Glycans, Eric Noel, Anna Notaro, Immacolata Speciale, Garry A. Duncan, Cristina De Castro, James L. Van Etten
Chlorovirus Pbcv-1 Multidomain Protein A111/114r Has Three Glycosyltransferase Functions Involved In The Synthesis Of Atypical N-Glycans, Eric Noel, Anna Notaro, Immacolata Speciale, Garry A. Duncan, Cristina De Castro, James L. Van Etten
Nebraska Center for Virology: Faculty Publications
The structures of the four N-linked glycans from the prototype chlorovirus PBCV-1 major capsid protein do not resemble any other glycans in the three domains of life. All known chloroviruses and antigenic variants (or mutants) share a unique conserved central glycan core consisting of five sugars, except for antigenic mutant virus P1L6, which has four of the five sugars. A combination of ge- netic and structural analyses indicates that the protein coded by PBCV-1 gene a111/114r, conserved in all chloroviruses, is a glycosyltransferase with three putative domains of approximately 300 amino acids each. Here, in addition to in silico sequence …
Strategies Targeting Hemagglutinin As A Universal Influenza Vaccine, Brianna L. Bullard, Eric A. Weaver
Strategies Targeting Hemagglutinin As A Universal Influenza Vaccine, Brianna L. Bullard, Eric A. Weaver
Nebraska Center for Virology: Faculty Publications
Influenza virus has significant viral diversity, both through antigenic drift and shift, which makes development of a vaccine challenging. Current influenza vaccines are updated yearly to in- clude strains predicted to circulate in the upcoming influenza season, however this can lead to a mismatch which reduces vaccine efficacy. Several strategies targeting the most abundant and im- munogenic surface protein of influenza, the hemagglutinin (HA) protein, have been explored. These strategies include stalk-directed, consensus-based, and computationally derived HA immunogens. In this review, we explore vaccine strategies which utilize novel antigen design of the HA protein to improve cross-reactive immunity for development …

Zika virus (ZIKV) infection to a pregnant woman can be vertically transmitted to the fetus via the placenta leading to Congenital Zika syndrome. This is characterized by microcephaly, retinal defects, and intrauterine growth retardation. ZIKV induces placental trophoblast apoptosis leading to severe abnormalities in the growth and development of the fetus. However, the molecular mechanism behind ZIKV-induced apoptosis in placental trophoblasts remains unclear. We hypothesize that ZIKV infection induces endoplasmic reticulum (ER) stress in the trophoblasts, and sustained ER stress results in apoptosis. HTR-8 (HTR-8/SVneo), a human normal immortalized trophoblast cell and human choriocarcinoma-derived cell lines (JEG-3 and JAR) were …

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is increasingly common in the adult population. In the United States, the overall burden of NAFLD is unknown due to challenges with population-level NAFLD detection. The purpose of this study was to estimate prevalence of NAFLD and significant NAFLD fibrosis and identify factors associated with them in the U.S.
METHODS: Data came from the 2017-2018 cycle of National Health and Nutrition Examination Survey. We defined NAFLD by controlled attenuation parameter (CAP) scores of ≥248 dB/m in absence of excessive alcohol use and viral hepatitis. We defined significant fibrosis as Vibration controlled transient elastography (VCTE) …

Stem cell-derived, organotypic in vitro models, known as organoids, have emerged as superior alternatives to traditional cell culture models due to their unparalleled ability to recreate complex physiological and pathophysiological processes. For this reason, they are attractive targets of tissue-engineering efforts, as constructs that include organoid technology would be expected to better simulate the many functions of the desired tissue or organ. While the 3D spheroidal architecture that is the default architecture of most organoid models may be preferred for some applications, 2D monolayer arrangements remain the preferred organization for many applications in tissue engineering. Therefore, in this work, we …

Endoscopic submucosal dissection (ESD) is a method of en-bloc resection of neoplastic colorectal lesions which is less invasive compared to surgical resection. Lesion stratification, architecture recognition and estimation of depth of invasion are crucial for patient selection. Expert endoscopists have integrated a variety of classification systems including Paris, lateral spreading tumor (LST), narrow band imaging (NBI), international colorectal endoscopic (NICE) and Japanese NBI expert team (JNET) in their day-to-day practice to enhance lesion detection accuracy. Major societies recommend ESD for LST-non granular (NG), Kudo-VI type, large depressed and protruded colonic lesions with shallow submucosal invasion. Chance of submucosal invasion enhances …

The interaction of extracellular matrix (ECM) components with hepatic stellate cells (HSCs) is thought to perpetuate fibrosis by stimulating signaling pathways that drive HSC activation, survival and proliferation. Consequently, disrupting the interaction between ECM and HSCs is considered a therapeutical avenue although respective targets and underlying mechanisms remain to be established. Here we have interrogated the interaction between type VI collagen (CVI) and HSCs based on the observation that CVI is 10-fold upregulated during fibrosis, closely associates with HSCs in vivo and promotes cell proliferation and cell survival in cancer cell lines. We exposed primary rat HSCs and a rat …
