BACKGROUND: Ductal carcinoma in situ (DCIS) can progress to invasive breast cancer (IBC), but often never will. As we cannot predict accurately which DCIS-lesions will or will not progress to IBC, almost all women with DCIS undergo breast-conserving surgery supplemented with radiotherapy, or even mastectomy. In some countries, endocrine treatment is prescribed as well. This implies many women with non-progressive DCIS undergo overtreatment. To reduce this, the LORD patient preference trial (LORD-PPT) tests whether mammographic active surveillance (AS) is safe by giving women with low-risk DCIS a choice between treatment and AS. For this, sufficient knowledge about DCIS is crucial. …

DNA methylation age (MA), brain age (BA), and frailty index (FI) are putative aging biomarkers linked to dementia risk. We investigated their relationship and combined potential for prediction of cognitive impairment and future dementia risk using the ADNI database. Of several MA algorithms, DunedinPACE and GrimAge2, associated with memory, were combined in a composite MA alongside BA and a data-driven FI in predictive analyses. Pairwise correlations between age- and sex-adjusted measures for MA (aMA), aBA, and aFI were low. FI outperformed BA and MA in all diagnostic tasks. A model including age, sex, and aFI achieved an area under the …

Background: Unplanned reattendances (UR) are an important quality indicator in the emergency department (ED). Understanding the risk factors associated with UR can aid clinicians in optimizing the allocation of time and resources, as well as targeted counselling for this specific group of patients. In this study, we aimed to compare patient characteristics between children who attended a pediatric emergency department (ED) with unplanned reattendances (UR) and those without UR. We also aimed to study the association between healthcare delivery factors such as timing of the attendance, patient load, changeover months for rotating junior doctors, presence of supervision, and rate of …

Shared Trauma: An Evolutionary Model Concept Analysis In Light Of Covid-19, April Hutto, Phyllis Raynor Phd, Aprn, Pmhnp-Bc, Beverly Baliko Phd, Rn, Pmhnp-Bc

Publications

Shared trauma (ST) is a term historically applied to social work experiences, but other healthcare professionals (HCP) also experience ST. With the occurrence of COVID-19, ST has impacted HCP globally and has led to new discoveries and more questions regarding its scope, impact and duration. This article aims to explore the concept of ST applied to nurses in light of COVID-19 using the Rogers and Knafl Evolutionary Model for Concept Analysis. Further examination and evolution of ‘shared trauma’, particularly during COVID-19, has led to the development of an adapted model to explore the implications of ST on health-related outcomes for …

Effect Of A Potent Nitrogenous Bisphosphonate On Cell Viability In Diabetic Conditions: An In Vitro Study On Human Fibroblasts And Pre-Osteoblasts, Denae Cantu, Bryan Liu, Deborah Rocha Seixas, Claudia Biguetti

School of Podiatric Medicine - Student Research

Introduction Zoledronate (Zol) is a nitrogenous bisphosphonate (nBP) used to treat osteoporosis, bone metastases, and Charcot foot. Despite its efficacy in preventing fractures, concerns exist about its side effects on mesenchyme-origin cells and impaired wound healing. We hypothesize that Zol may impair the responses of human fibroblasts (hF) and pre-osteoblasts (MC3T3), potentially compromising tissue healing in the lower extremities of patients with diabetes.

Methodology: MC3T3 cells and hF were cultured in 96-well plates at a density of 2.5 x 10³ cells for 48 and 72 hours, respectively. Cells were subjected to normal glucose, high glucose, and high oxidative stress conditions …

Thioredoxin: An Antioxidant, A Therapeutic Target And A Possible Biomarker, Tara Sudhadevi, Anantha Harijith

Faculty Scholarship

Study by Haga et al. on the utility of neonatal serum thioredoxin-1 (TRX-1) levels as a biomarker of bronchopulmonary dysplasia (BPD)/ retinopathy of prematurity (ROP) is the first of its kind. A biomarker is considered to enable the detection of a pathological condition or its severity and ideally, should have the capacity to be detected in the pre-disease state or during the diseased state. Premature infants who develop BPD are exposed to supplemental O2 and show marked evidence of oxidant stress as suggested by elevated glutathione disulfide (GSSG) concentrations.1 Upon preterm delivery, an infant breathing even atmospheric oxygen of 21% …

Prazosin As An Adjuvant To Increase Effectiveness Of Duloxetine In A Rat Model Of Oxaliplatin-Induced Peripheral Neuropathy, Monica A. Wagner, Naji Ayyash

Faculty Scholarship

Objectives: Duloxetine, the only American Society of Clinical Oncology (ASCO) treatment recommended for chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors, is not effective for 40% of survivors. This study examined the ability of a duloxetine-prazosin combination to prevent the development of allodynia and hyperalgesia in a rat model of oxaliplatin-induced peripheral neuropathy (OPIN). Methods: Female (n = 24) and male (n = 41) rats were started on duloxetine (15 mg), prazosin (2 mg), or a duloxetine-prazosin combination one week prior to administration of the chemotherapy drug, oxaliplatin, and continued the duloxetine-prazosin combination for 32 days. Behavioral testing for mechanical allodynia …

Integrin Α6Β4 Upregulates Ptprz1 Through Uchl1-Mediated Hif-1Α Nuclear Accumulation To Promote Triple-Negative Breast Cancer Cell Invasive Properties, Min Chen, Parvanee A. Karimpour, Andrew Elliott, Daheng He, Teresa Knifley, Jinpeng Liu, Chi Wang, Kathleen L. O’Connor

Markey Cancer Center Faculty Publications

Integrin α6β4 drives triple-negative breast cancer (TNBC) aggressiveness through the transcriptional regulation of key genes. Here, we investigated how integrin α6β4 regulates protein tyrosine phosphatase receptor type Z1 (PTPRZ1). Using stable re-expression of integrin β4 (ITGB4) in cells naturally devoid of integrin α6β4 or knockdown or knockout (KO) of ITGB4, we found that integrin α6β4 regulates PTPRZ1 expression. To gain mechanistic insight, we focused on Hif-1α due to the impact of integrin α6β4 on a hypoxia-associated signature. We found that nuclear localization of Hif-1α, but not Hif-2α, was substantially enhanced with integrin α6β4 signaling. Hif-1α knockdown by shRNA or chemical …

Excessive fructose intake is a risk factor for the development of obesity and its complications. Targeting ketohexokinase (KHK), the first enzyme of fructose metabolism, has been investigated for the management of metabolic dysfunction–associated steatotic liver disease (MASLD). We compared the effects of systemic, small molecule inhibitor of KHK enzymatic activity with hepatocyte-specific, N-acetylgalactosamine siRNA–mediated knockdown of KHK in mice on an HFD. We measured KHK enzymatic activity, extensively quantified glycogen accumulation, performed RNA-Seq analysis, and enumerated hepatic metabolites using mass spectrometry. Both KHK siRNA and KHK inhibitor led to an improvement in liver steatosis; however, via substantially different mechanisms, KHK …

Markey Cancer Center Faculty Publications

BACKGROUND: We examined the cost-effectiveness of providing systematic smoking cessation interventions to oncology patients at point-of-care.

METHODS: A decision analytic model was completed from the healthcare payer's perspective and included all incident cancer cases involving patients who smoke in New Brunswick, Canada (n = 1040), cancer site stratifications, and risks of mortality, continued smoking, and cancer treatment failure over one year. Usual care (no cessation support) was compared to the standard Ottawa Model for Smoking Cessation (OMSC) intervention, and to OMSC plus unlimited cost-free stop smoking medication (OMSC + SSM), including nicotine replacement therapy, varenicline, or bupropion. Primary outcomes were …

Predicting The Pathway Involvement Of All Pathway And Associated Compound Entries Defined In The Kyoto Encyclopedia Of Genes And Genomes, Erik D. Huckvale, Hunter Moseley

Markey Cancer Center Faculty Publications

Background/Objectives: Predicting the biochemical pathway involvement of a compound could facilitate the interpretation of biological and biomedical research. Prior prediction approaches have largely focused on metabolism, training machine learning models to solely predict based on metabolic pathways. However, there are many other types of pathways in cells and organisms that are of interest to biologists. Methods: While several publications have made use of the metabolites and metabolic pathways available in the Kyoto Encyclopedia of Genes and Genomes (KEGG), we downloaded all the compound entries with pathway annotations available in the KEGG. From these data, we constructed a dataset where each …

Upregulation Of Fatty Acid Synthase Increases Activity Of Β-Catenin And Expression Of Notum To Enhance Stem-Like Properties Of Colorectal Cancer Cells, Courtney O. Kelson, Josiane Weber Tessmann, Mariah E. Geisen, Daheng He, Chi Wang, Tianyan Gao, B. Mark Evers, Yekaterina Y. Zaytseva

Markey Cancer Center Faculty Publications

Dysregulated fatty acid metabolism is an attractive therapeutic target for colorectal cancer (CRC). We previously reported that fatty acid synthase (FASN), a key enzyme of de novo synthesis, promotes the initiation and progression of CRC. However, the mechanisms of how upregulation of FASN promotes the initiation and progression of CRC are not completely understood. Here, using Apc/VillinCre and ApcMin mouse models, we show that upregulation of FASN is associated with an increase in activity of β-catenin and expression of multiple stem cell markers, including Notum. Genetic and pharmacological downregulation of FASN in mouse adenoma organoids decreases the activation of β-catenin …

The Absence Of Cxcl10 Activity Does Not Affect The Capability Of Cd8+ T Cells To Migrate And Eliminate The Tissue Cysts Of Toxoplasma Gondii From The Brains Of Chronically Infected Mice, Rajesh Mani, Yasuhiro Suzuki

Markey Cancer Center Faculty Publications

Toxoplasma gondii forms tissue cysts in neurons and astrocytes in the brain to establish chronic infection, and astrocytes express the CXCL10 chemokine in chronically infected mice. Since chemokines mediate the migration of T cells to attack their targets, and since CXCL10 plays key roles in T cell-mediated control of the proliferation of tachyzoites (the acute stage form) of T. gondii during the acute stage of infection, we examined whether CXCL10 is involved in recruiting anti-cyst CD8+ cytotoxic T cells to eliminate the cysts in their brains. We employed adoptive transfer of CD8+ immune T cells to infected, T cell-deficient SCID …

The Impact Of Pdcd4, A Translation Inhibitor, On Drug Resistance, Qing Wang, Hsin-Sheng Yang

Markey Cancer Center Faculty Publications

Programmed cell death 4 (Pdcd4) is a tumor suppressor, which has been demonstrated to efficiently suppress tumorigenesis. Biochemically, Pdcd4 binds with translation initiation factor 4A and represses protein translation. Beyond its role in tumor suppression, growing evidence suggests that Pdcd4 enhances the chemosensitivity of several anticancer drugs. To date, numerous translational targets of Pdcd4 have been identified. These targets govern important signal transduction pathways, and their attenuation may improve chemosensitivity or overcome drug resistance. This review will discuss the signal transduction pathways regulated by Pdcd4 and the potential mechanisms through which Pdcd4 enhances chemosensitivity or counteracts drug resistance.

Background: The mortality of cardiac conditions in infancy is improving with advances in surgical planning and medical management. Neurologic morbidity remains significant. Clinically correlating an infant with their neurologic exam, MRI/EEG, and subsequent developmental testing remains a challenge. Counseling regarding neurologic outcomes after cardiac intervention is difficult due to the wide range of findings that can sometimes be clinically irrelevant. Purpose: The goal of this study is to identify factors associated with poor neurodevelopmental outcomes in infants with critical congenital heart defects (CCHD) as assessed by the Bayley Scales of Infant and Toddler Development Edition IV (Bayley). Methods: This is …

Increased Red Cell Distribution Width (Rdw) Is Associated With Culture Positive Sepsis And With Increased Need Of Escalation In Respiratory Support In Very Low Birth Weight Infants More Than Seven Days Of Life Undergoing Sepsis Workup Secondary To Vitals Instability In The Form Of Multiple Episodes Of True Apneas Or Bradycardia And Desaturations Associated With Apnea, Kedar Tilak, Aashka Patel, Anna Zylak

Posters

Background Apnea of prematurity is nearly universal among very low birth weight infants (VLBW). In VLBW infants, changes in clinical status usually occur due to sepsis or non-infectious causes and it is challenging to differentiate between the two. We as clinicians use irregularities in vital signs as an early warning sign of sepsis to facilitate early treatment and improve patient outcomes. Adults have used RDW as a marker of worsening respiratory status and mortality from acute respiratory distress syndrome (ARDS). In this study, we seek to investigate elevations in Red Cell Distribution Width (RDW) as markers for culture positive sepsis …

Faculty, Staff and Students Publications

Anger outbursts (AO) are associated with severe symptoms, impairment and poorer treatment outcomes for anxious children, though limited research has examined AO in youth with co-occurring autism and anxiety disorders. This study examined AO in children with autism and anxiety by evaluating clinical characteristics, family accommodation, and changes in AO following anxiety-focused treatment. The sample comprised 167 youth with autism and anxiety enrolled in a multi-site randomized clinical trial comparing standard care CBT for anxiety, CBT adapted for youth with autism, and usual care. Most participants (60%) had AO, which contributed to impairment above and beyond anxiety and autism. AO …
