Geriatric Depression Screening And Chief Complaint: What Is The Risk For 30- And 90-Day Readmission?, Eric James, Joan Michelle Moccia, Victoria Lucia

Journal of Geriatric Emergency Medicine

Abstract

Background:

Readmission to the hospital within 30-days has a high cost and represents a gap in care for older adults. Older adults are at significant risk for depression, particularly given their medical comorbidities and social factors such as isolation due to SARS-CoV-2. Many patients who screen positive for depression may have no known history of depression. This investigation examines the relationship between a positive geriatric depression screen and chief complaint as a function of 30- and 90-day readmission risk.

Methods:

We examined the electronic medical record of 329 older adults aged 65 and older from February 1, 2020, to …

Colon Cancer Screening And The Association With Colon Cancer Incidence And Mortality Rates In Ethnic Minority Groups, Jovonne Smith

Student Scholar Showcase

Colorectal cancer (CRC) continues to be a public health burden and is the second leading cause of American cancer deaths. Strides have been made in the medical community, and there has been an overall decrease in CRC rates. This decrease is primarily due to a cumulative decline in late-onset colorectal cancer diagnosis (LOCRC), defined as CRC cancer in adults over the age of 50 years. CRC continues to burden American Indians and Alaska Natives (AIAN) and Non-Hispanic Black individuals (NHB) disproportionately. The incidence and mortality rates remain disproportionately higher than other ethnic groups, and the survival rate is lower than …

Nebraska Center for Virology: Faculty Publications

Non-typhoidal Salmonella is the tremendously predominant source of acquired foodborne infection in humans, causing salmonellosis which is a global threat to the healthcare system. This threat is even worse when it is combined with the incidence of multidrug-resistant Salmonella strains. Bacteriophage therapy has been proposed as a promising potential candidate to control a diversity of foodborne infective bacteria. The objective of this study designed to isolate and characterize lytic phages infecting zoonotic multi-drug resistant and strong biofilm producer Salmonella enterica serovar Enteritidis EG.SmE1 and then apply the isolated phage/s as a biocontrol agent against infections in ready-to-eat food articles including …

The Sars-Cov-2 Utr’S Intrudes Host Rbp’S And Modulates Cellular Splicing, Anjali Singh, Kush Kumar Pandey, Shubham Kumar Agrawal, Rupesh K. Srivastava, Sankar Bhattacharyya, Bhupendra Verma

Nebraska Center for Virology: Faculty Publications

SARS-CoV-2 is a novel coronavirus that causes a potentially fatal respiratory disease known as coronavirus disease (COVID-19) and is responsible for the ongoing pandemic with increasing mortality. Understanding the host-virus interaction involved in SARS-CoV-2 pathophysiology will enhance our understanding of the mechanistic basis of COVID-19 infection. The characterization of post-transcriptional gene regulatory networks, particularly pre-mRNA splicing, and the identification and characterization of host proteins interacting with the 5' and 3'UTRs of SARS-CoV-2 will improve our understanding of posttranscriptional gene regulation during SARS-CoV-2 pathogenesis. Here, we demonstrate that either SARS-CoV-2 infection or exogenous overexpression of the 5' and 3’UTRs of the …

Wolfe

Biostatistics Collaborative Core: Faculty Publications and Other Works

Introduction: Intravesical therapy (IVT), including Bacillus Calmette-Guérin (BCG), is the standard of care for high grade (HG) non-muscle invasive bladder cancer (NMIBC). Despite the use of IVT, many patients recur after treatment. The bladder microbiome and its role in disease processes has recently risen to prominence. We aim to characterize changes that occur in the bladder microbiome over the course of intravesical therapy and assess whether these changes correlate with outcomes in patients with NMIBC.

Methods: Patients with NMIBC undergoing induction BCG or intravesical therapy were prospectively enrolled from January 2019 to March 2020. Patients with clinical T2 or greater …

Faculty, Staff and Student Publications

BACKGROUND: Bladder cancer (BC) is among the most common cancers diagnosed in men in the USA. The current gold standards for the diagnosis of BC are invasive or lack the sensitivity to correctly identify the disease.

METHODS: An aptamer-based screen analyzed the expression of 1317 proteins in BC compared to urology clinic controls. The top hits were subjected to systems biology analyses. Next, 30 urine proteins were ELISA-validated in an independent cohort of 68 subjects. Three of these proteins were next validated in an independent BC cohort of differing ethnicity.

RESULTS: Systems biology analysis implicated molecular functions related to the …

Multicentre Study Protocol Comparing Standard Nrp To Developed Educational Modules For Resuscitation Of Neonates In The Delivery Room With Congenital Heart Disease (Learn-Chd)., Philip Levy, Alyssa R. Thomas, Brenda Hiu Yan Law, Chloe Joynt, Ruby Gupta, Summer Elshenawy, Danielle Reed, Leeann R. Pavlek, Jennifer Shepherd, Sharada Gowda, Beth Ann Johnson, Molly Ball, Noorjahan Ali

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Infants born with critical congenital heart defects (CCHDs) have unique transitional pathophysiology that often requires special resuscitation and management considerations in the delivery room (DR). While much is known about neonatal resuscitation of infants with CCHDs, current neonatal resuscitation guidelines such as the neonatal resuscitation programme (NRP) do not include algorithm modifications or education specific to CCHDs. The implementation of CCHD specific neonatal resuscitation education is further hampered by the large number of healthcare providers (HCPs) that need to be reached. Online learning modules (eLearning) may provide a solution but have not been designed or tested for this specific …

Evaluation Of Focal Adhesion Mediated Subcellular Curvature Sensing In Response To Engineered Extracellular Matrix, Daniel T Bowers, Mary Elizabeth Mcculloch, Justin L Brown

Faculty, Staff and Student Publications

Fibril curvature is bioinstructive to attached cells. Similar to natural healthy tissues, an engineered extracellular matrix can be designed to stimulate cells to adopt desired phenotypes. To take full advantage of the curvature control in biomaterial fabrication methodologies, an understanding of the response to fibril subcellular curvature is required. In this work, we examined morphology, signaling, and function of human cells attached to electrospun nanofibers. We controlled curvature across an order of magnitude using nondegradable poly(methyl methacrylate) (PMMA) attached to a stiff substrate with flat PMMA as a control. Focal adhesion length and the distance of maximum intensity from the …

Co-Occurrence Of Depression, Anxiety, And Perinatal Posttraumatic Stress In Postpartum Persons, Shelby Howard, Caitlin Witt, Karla Martin, Ateshi Bhatt, Emily Venable, Sarah Buzhardt, Andrew G. Chapple, Elizabeth F. Sutton

School of Medicine Faculty Publications

Background: The study aim was to describe the incidence of depression, anxiety, perinatal-post-traumatic stress disorder (PTSD), and their co-occurrences in the early postpartum period in a low-resource OB/GYN clinic serving majority Medicaid-eligible persons. We hypothesized that postpartum persons screening positive for depression will have an increased risk of a positive screen for anxiety and perinatal PTSD. Methods: A retrospective study of postpartum persons receiving care in Baton Rouge, Louisiana was conducted using responses abstracted from the electronic medical record (EMR) of the Patient Health Questionnaire-9 (PHQ9), Generalized Anxiety Disorder-7 (GAD7), and Perinatal Post Traumatic Stress Disorder Questionnaire-II (PPQII). Categorical distributions …

Background: Delays in access to educational services for autism are common and more likely among children from families of color and/or with low income. In-person family navigation accelerates autism diagnosis; however, the effectiveness of telehealth autism diagnostic navigation is unknown.

Objectives: To test preliminary feasibility and efficacy of a telehealth autism navigation program.

Method: This was a site-randomized pilot trial of autism family navigation for Oregon children in 2021-2022. The intervention used layperson family resource specialists based at Oregon’s Help Me Grow program as navigators for families of children with autism symptoms. Pediatric clinics with >30% Medicaid, located in 5 …

Dpp8 Selective Inhibitor Tominostat As A Novel And Broad-Spectrum Anticancer Agent Against Hematological Malignancies, Shohei Kikuchi, Akinori Wada, Yusuke Kamihara, Kosuke Okazaki, Paras Jawaid, Mati Ur Rehman, Eiji Kobayashi, Takeshi Susukida, Tomoki Minemura, Yoshimi Nabe

Department of Biological & Biomedical Sciences

DPP8/9 inhibition induces either pyroptotic or apoptotic cell death in hematological malignancies. We previously reported that treatment with the DPP8/9 inhibitor 1G244 resulted in apoptotic cell death in myeloma, and our current study further evaluates the mechanism of action of 1G244 in different blood cancer cell lines. Specifically, 1G244 inhibited DPP9 to induce GSDMD-mediated-pyroptosis at low concentrations and inhibited DPP8 to cause caspase-3-mediated-apoptosis at high concentrations. HCK expression is necessary to induce susceptibility to pyroptosis but does not participate in the induction of apoptosis. To further characterize this DPP8-dependent broad-spectrum apoptosis induction effect, we evaluated the potential antineoplastic role for …

Temporal Machine Learning Analysis Of Prior Mammograms For Breast Cancer Risk Prediction, Hui Li, Kayla Robinson, Li Lan, Natalie Baughan, Chun-Wai Chan, Matthew Embury, Gary J Whitman, Randa El-Zein, Isabelle Bedrosian, Maryellen L Giger

Faculty, Staff and Student Publications

The identification of women at risk for sporadic breast cancer remains a clinical challenge. We hypothesize that the temporal analysis of annual screening mammograms, using a long short-term memory (LSTM) network, could accurately identify women at risk of future breast cancer. Women with an imaging abnormality, which had been biopsy-confirmed to be cancer or benign, who also had antecedent imaging available were included in this case-control study. Sequences of antecedent mammograms were retrospectively collected under HIPAA-approved guidelines. Radiomic and deep-learning-based features were extracted on regions of interest placed posterior to the nipple in antecedent images. These features were input to …

Parp Inhibitors For The Treatment Of Brca1/2-Mutated Metastatic Breast Cancer: A Systematic Review And Meta-Analysis, Ranju Kunwor, Daniel P. Silver, Maysa Abu-Khalaf

Kimmel Cancer Center Faculty Papers

BACKGROUND: The PARP inhibitors (PARPis) olaparib and talazoparib are currently approved for the treatment of deleterious germline BRCA1/2-mutated (gBRCA+) metastatic breast cancer (MBC). These approvals were based on improvements in progression-free survival (PFS) observed in two randomized controlled trials (RCTs). Other PARPis, such as veliparib and niraparib, have also been studied. We conducted this meta-analysis of RCTs to assess the PFS and overall survival (OS) benefits of PARPis in gBRCA + MBC.

METHODS: We performed a systematic search for RCTs using the Cochrane Library, PubMed, Embase, and Web of Science databases up to March 2021. Only phase II and III …

Pre-Transplant Evaluation Period Efficiency Through The Use Of An Electronic Scheduling Template, Christy Dawn Byrd

Student Scholarly Projects

Practice Problem: Candidacy for transplant evaluation is a complex and lengthy evaluation process. Delays in National Organ Registry have significant unfavorable impacts on patient outcomes as 22 people a day die awaiting a lifesaving treatment. Operational efficiencies can improve the pre-transplant evaluation period and significantly improve patient outcomes.

PICOT: In an outpatient transplant clinic (P), will leveraging an evidence-based scheduling template (I) compared to the current practice of first available appointment (C) reduce the evaluation period by 66% from a 3–4-week evaluation to a 1-week evaluation resulting in expedited listing on the National Organ Registry (O), when applied over …

Associations between human genetic variation and clinical phenotypes have become a foundation of biomedical research. Most repositories of these data seek to be disease-agnostic and therefore lack disease-focused views. The Type 2 Diabetes Knowledge Portal (T2DKP) is a public resource of genetic datasets and genomic annotations dedicated to type 2 diabetes (T2D) and related traits. Here, we seek to make the T2DKP more accessible to prospective users and more useful to existing users. First, we evaluate the T2DKP's comprehensiveness by comparing its datasets with those of other repositories. Second, we describe how researchers unfamiliar with human genetic data can begin …

The Dietary Approaches to Stop Hypertension (DASH) diet is recommended for cardiovascular disease prevention. We aimed to identify protein biomarkers of the DASH diet using data from 2 randomized feeding studies and validate them in an observational study, the ARIC (Atherosclerosis Risk in Communities) study.

Methods and Results

Large‐scale proteomic profiling was conducted in serum specimens (SomaLogic) collected at the end of 8‐week and 4‐week DASH diet interventions in multicenter, randomized controlled feeding studies of the DASH trial (N=215) and the DASH‐Sodium trial (N=396), respectively. Multivariable linear regression models were used to compare the relative abundance of 7241 proteins …

Successful Heart-Liver Transplant Using Dual-Organ Normothermic Perfusion In A Patient With Fontan Failure, Anton Kozyryev, Daniel Lemen, Jessica Dunn, Steven E Rokita

Faculty, Staff and Student Publications

Iodotyrosine deiodinase (IYD) is unusual in its reliance on flavin to promote reductive dehalogenation of halotyrosines under aerobic conditions. Applications of this activity can be envisioned for bioremediation, but expansion of its specificity requires an understanding of the mechanistic steps that limit the rate of turnover. Key processes capable of controlling steady-state turnover have now been evaluated and described in this study. While proton transfer is necessary for converting the electron-rich substrate into an electrophilic intermediate suitable for reduction, kinetic solvent deuterium isotope effects suggest that this process does not contribute to the overall efficiency of catalysis under neutral conditions. …

Breakthrough SARS-CoV-2 infections of vaccinated individuals are being reported globally, resulting in an increased risk of hospitalization and death among such patients. Therefore, it is crucial to identify the modifiable risk factors that may affect the protective efficacy of vaccine use against the development of severe COVID-19 and thus to initiate early medical interventions. Here, in population-based studies using the UK Biobank database and the 2021 National Health Interview Survey (NHIS), we analyzed 20,362 participants aged 50 years or older and 2,588 aged 18 years or older from both databases who tested positive for SARS-COV-2, of whom 33.1% and 67.7% …

Pattern Dynamics And Stochasticity Of The Brain Rhythms, Clarissa Hoffman, Jingheng Cheng, Daoyun Ji, Yuri Dabaghian

Faculty, Staff and Student Publications

Our current understanding of brain rhythms is based on quantifying their instantaneous or time-averaged characteristics. What remains unexplored is the actual structure of the waves-their shapes and patterns over finite timescales. Here, we study brain wave patterning in different physiological contexts using two independent approaches: The first is based on quantifying stochasticity relative to the underlying mean behavior, and the second assesses "orderliness" of the waves' features. The corresponding measures capture the waves' characteristics and abnormal behaviors, such as atypical periodicity or excessive clustering, and demonstrate coupling between the patterns' dynamics and the animal's location, speed, and acceleration. Specifically, we …

Left-right asymmetry is an important organizing feature of the healthy brain that may be altered in schizophrenia, but most studies have used relatively small samples and heterogeneous approaches, resulting in equivocal findings. We carried out the largest case-control study of structural brain asymmetries in schizophrenia, with MRI data from 5,080 affected individuals and 6,015 controls across 46 datasets, using a single image analysis protocol. Asymmetry indexes were calculated for global and regional cortical thickness, surface area, and subcortical volume measures. Differences of asymmetry were calculated between affected individuals and controls per dataset, and effect sizes were meta-analyzed across datasets. Small …

Infection remains a serious complication associated with the cardiac implantable electronic devices (CIEDs), leading to substantial clinical and economic burden globally. This review assesses the burden of cardiac implantable electronic device infection (CIED-I), evidence for treatment recommendations, barriers to early diagnosis and appropriate therapy, and potential solutions. Multiple clinical practice guidelines recommended complete system and lead removal for CIED-I when appropriate. CIED extraction for infection has been consistently reported with high success, low complication, and very low mortality rates. Complete and early extraction was associated with significantly better clinical and economic outcome compared with no or late extraction. However, significant …

UNLABELLED: In acute myeloid leukemia (AML), SWI/SNF chromatin remodeling complexes sustain leukemic identity by driving high levels of MYC. Previous studies have implicated the hematopoietic transcription factor PU.1 (SPI1) as an important target of SWI/SNF inhibition, but PU.1 is widely regarded to have pioneer-like activity. As a result, many questions have remained regarding the interplay between PU.1 and SWI/SNF in AML as well as normal hematopoiesis. Here we found that PU.1 binds to most of its targets in a SWI/SNF-independent manner and recruits SWI/SNF to promote accessibility for other AML core regulatory factors, including RUNX1, LMO2, and MEIS1. SWI/SNF inhibition …

The microenvironment that surrounds pancreatic ductal adenocarcinoma (PDAC) is profoundly desmoplastic and immunosuppressive. Understanding triggers of immunosuppression during the process of pancreatic tumorigenesis would aid in establishing targets for effective prevention and therapy. Here, we interrogated differential molecular mechanisms dependent on cell of origin and subtype that promote immunosuppression during PDAC initiation and in established tumors. Transcriptomic analysis of cell-of-origin-dependent epithelial gene signatures revealed that Nt5e/CD73, a cell-surface enzyme required for extracellular adenosine generation, is one of the top 10% of genes overexpressed in murine tumors arising from the ductal pancreatic epithelium as opposed to those rising from acinar cells. …

Combatting Abortion Misinformation And Disinformation In Medical Education, Jaya Prakash, Deborah Bartz

Feminist Pedagogy

Abstract Introduction: Although abortion has historically been federally legal, functional access to abortion care has been thwarted by inflammatory political discourse. Abortion misinformation and disinformation have been deliberately intertwined into political agendas and ideologies, widening the gap between the lay public’s perception of and patients’ lived experience with abortion care. The politicization of abortion care has adverse effects on its provision and training along lines of inequity and marginalization established by preexisting systems of oppression and structural violence. Critical feminist pedagogy—an examination of class, gender, and sexuality on patriarchal misrepresentations of abortion information—can guide medical students to recognize and combat …

Purpose: Our team previously identified the presence of five corneal resonant frequency (RF) peaks in healthy volunteers using vibrational optical coherence tomography (VOCT). Prior studies have suggested that the ≤100 Hz RF peak represents the cellular element of tissue. The aim of this study was to confirm that this peak reflects the human corneal cellular component using VOCT and histological analysis.

Methods: Two human research globes were obtained from the same donor, and VOCT measurements were collected from the full-thickness corneas. A microkeratome was then used to create serial-free corneal caps from each cornea, with VOCT performed on the residual …
