Department of Paediatrics and Child Health

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, …

Contextualizing The Young Adult Female Breast Cancer Experience: Developmental, Psychosocial, And Interpersonal Influences, Cameron Froude, Sandra Rigazio-Digilio, Laura Donorfio, Keith Bellizzi

The Qualitative Report

Breast cancer is the most common cancer among American women (American Cancer Society [ACS], 2016b). Adolescents and young adults (AYAs) as a group have a worse prognosis when compared to older adults (e.g., Tichy, Lim, & Anders, 2013). Due to limited understanding of the biology of cancers for AYAs, inadequate representation of AYAs in clinical trials, and AYAs’ unique psychosocial healthcare needs, the prognosis for this group, as compared to older women, is comparatively poor. One step in addressing the survival gap for AYAs is to explore the developmental and psychosocial factors that shape their illness experiences. This qualitative study …

Case-Control Vaccine Effectiveness Studies: Preparation, Design, And Enrollment Of Cases And Control, Jennifer R. Verani, Abdullah H. Baqui, Claire V. Broome, Thomas Cherian, Cheryl Cohen, Jennifer L. Farrar, Daniel R. Feikin, Michelle J. Groome, Rana A. Hajjeh, Anita K. M. Zaidi

Department of Paediatrics and Child Health

Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we …

Montreal’s Aboriginal population is growing rapidly, yet the community lacks a culturally safe and holistic health service center that is accessible to all Aboriginal people. On Friday, June 2, 2017 The Montreal Urban Aboriginal Health Centre (MUAHC) joined forces with Next City & Concordia University to co-create a 7-minute pitch for a $7,000 prize through the Vangaurd Conference Big Idea Challenge. An interdisciplinary team of 8 conference attendees worked with MUAHC leadership to design a short-term solution that would be a step in the right direction towards MUAHC’s goal to build a fully functioning and independent health center dedicated …

Toxoplasma Gondii Moderates The Association Between Multiple Folate-Cycle Factors And Cognitive Function In U.S. Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (T. gondii) is a microscopic, apicomplexan parasite that can infect muscle or neural tissue, including the brain, in humans. While T. gondii infection has been associated with changes in mood, behavior, and cognition, the mechanism remains unclear. Recent evidence suggests that T. gondii may harvest folate from host neural cells. Reduced folate availability is associated with an increased risk of neurodevelopmental disorders, neurodegenerative diseases, and cognitive decline. We hypothesized that impairment in cognitive functioning in subjects seropositive for T. gondii might be associated with a reduction of folate availability in neural cells. We analyzed data from the third …

Plasmonic Gold Nanoparticle For Detection Of Fungi And Human Cutaneous Fungal Infections, Tobiloba Sojinrin, Kangze Liu, Joao Conde, Hugh Byrne, James Curtin, Daxiang Cui, Furong Tian

Articles

Fungi, which are common in the environment, can cause a multitude of diseases. Warm, humid conditions allow fungi to grow and infect humans via the respiratory, digestive and reproductive tracts, genital area and other bodily interfaces. Fungi can be detected directly by microscopy, using the potassium hydroxide (KOH) test, which is the gold standard and most popular method for fungal screening. However, this test requires trained personnel operating specialist equipment, including a fluorescent microscope and culture facilities. As most acutely infected patients seek medical attention within the first few days of symptoms, the optimal diagnostic test would be rapid and …

Swords Into Ploughshares: Agricultural Recovery And Postwar Institutional Development In Sub-Saharan Africa, Jinu R. Abraham

Dissertations, Theses, and Capstone Projects

Civil wars have long been characterized in the comparative politics literature as having profoundly negative economic effects for both individual households and countries on a larger scale. However, variation in postwar economic outcomes indicates that conflict may indeed have some curative effects. I argue political settlements in the aftermath of civil wars can shape postwar economic outcomes by transforming institutions critical to agricultural productivity. The structure of the state postwar can shape land tenure security, local government participation, and the management of preexisting social divisions. I employ a case study method controlling for differences on the independent variable in order …

Reducing Mortality From Septic Shock Using An Interleukin-1 Receptor Antagonist, Juyeon Chung

Yale School of Medicine Physician Associate Program Theses

Septic shock, a severe inflammatory state secondary to a bacterial infection with refractory hypotension and tissue hypoperfusion despite adequate fluid resuscitation, is a leading cause of mortality in intensive care units worldwide. The mortality rate of septic shock patients can exceed 40% in the U.S., highlighting the need for more effective therapies. Anakinra, an inflammatory cytokine inhibitor, has been identified as a potential therapy for reducing various inflammatory states such as sepsis. Our aim is to evaluate the efficacy of anakinra in reducing mortality in patients with septic shock. This double-blind, randomized control trial will compare the 28-day mortality of …

Subsets Of Inflammatory Cytokine Gene Polymorphisms Are Associated With Risk Of Carcinogenic Liver Fluke Opisthorchis Viverrini-Associated Advanced Periductal Fibrosis And Cholangiocarcinoma., Arpa Surapaitoon, Sutas Suttiprapa, Eimorn Mairiang, Narong Khuntikeo, Chawalit Pairojkul, Jeffrey Bethony, Paul J Brindley, Banchob Sripa

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Opisthorchis viverrini infection induces chronic inflammation, and a minor proportion of infected individuals develop advanced periductal fibrosis (APF) and cholangiocarcinoma (CCA). Inflammatory cytokines and/or their gene polymorphisms may link to these biliary pathologies. We therefore investigated associations among cytokine gene polymorphisms and cytokine production in 510 Thai cases infected with O. viverrini who presented with APF+ or APF−, as established by abdominal ultrasonography as well as in patients diagnosed with CCA. Levels of pro-inflammatory and anti-inflammatory cytokines were determined in culture supernatants after stimulation of peripheral blood mononuclear cells (PBMCs) with O. viverrini excretory-secretory (ES) products. Pro-inflammatory cytokines, IL-1β, IL-6, …

Implementing A Metapopulation Bass Diffusion Model Using The R Package Desolve, Jim Duggan

The R Journal

Diffusion is a fundamental process in physical, biological, social and economic settings. Consumer products often go viral, with sales driven by the word of mouth effect, as their adoption spreads through a population. The classic diffusion model used for product adoption is the Bass diffusion model, and this divides a population into two groups of people: potential adopters who are likely to adopt a product, and adopters who have purchased the product, and influence others to adopt. The Bass diffusion model is normally captured in an aggregate form, where no significant consumer differences are modeled. This paper extends the Bass …

Cross-Talk Between Clinical And Host-Response Parameters Of Periodontitis In Smokers, Radha Nagarajan, Craig S. Miller, Dolph R. Dawson Iii, Mohanad Al-Sabbagh, Jeffrey L. Ebersole

Institute for Biomedical Informatics Faculty Publications

Background and Objective

Periodontal diseases are a major public health concern leading to tooth loss and have also been shown to be associated with several chronic systemic diseases. Smoking is a major risk factor for the development of numerous systemic diseases, as well as periodontitis. While it is clear that smokers have a significantly enhanced risk for developing periodontitis leading to tooth loss, the population varies regarding susceptibility to disease associated with smoking. This investigation focused on identifying differences in four broad sets of variables, consisting of: (i) host‐response molecules; (ii) periodontal clinical parameters; (iii) antibody responses to periodontal pathogens …

Salivary And Serum Adiponectin And C-Reactive Protein Levels In Acute Myocardial Infarction Related To Body Mass Index And Oral Health, Jeffrey L. Ebersole, Richard J. Kryscio, C. Campbell, D. F. Kinane, J. Mcdevitt, N. Christodoulides, P. N. Floriano, Craig S. Miller

Oral Health Practice Faculty Publications

Background and Objective

Adiponectin is produced by adipose cells and is considered an anti‐inflammatory molecule. In contrast, C‐reactive protein (CRP) has been identified as a hallmark of systemic inflammation and used as a risk marker of cardiovascular disease (CVD). Of interest was the relationship of these two biomarkers to oral health and CVD risk.

Material and Methods

This investigation examined these two molecules in serum and unstimulated whole saliva of patients within 48 h of an acute myocardial infarction (AMI) compared to control subjects. We hypothesized a differential response in these biomolecules resulting from the heart attack that would be …

Liu, Brent A. Stanfield, Vladimir N. Chouljenko, Shan Naidu, Ingeborg Langohr, Fabio Del Piero, Jacqueline Ferracone, Alma A. Roy, Konstantin G. Kousoulas

Faculty Publications

© 2017 American Society for Microbiology. All Rights Reserved. Vaccination remains the best option to combat equine herpesvirus 1 (EHV-1) infection, and several different strategies of vaccination have been investigated and developed over the past few decades. Herein, we report that the liveattenuated herpes simplex virus 1 (HSV-1) VC2 vaccine strain, which has been shown to be unable to enter into neurons and establish latency in mice, can be utilized as a vector for the heterologous expression of EHV-1 glycoprotein D (gD) and that the intramuscular immunization of mice results in strong antiviral humoral and cellular immune responses. The VC2-EHV-1-gD …

Arts & Sciences Faculty Publications

The marine flora of Panama harbors a rich diversity of green, red and brown algae, and despite chronic understudy, it is reported as the second most diverse marine flora along the Pacific Central American coast, with 174 macroalgal species. Extensive new collections and molecular assisted identification (MAI) by an international team of researchers has revealed an even greater diversity for this country. Here, the intertidal and shallow subtidal marine flora of the remote Burica Peninsula is introduced. This area is characterized by an uplifted extensive intertidal flat composed of firm, sedimentary benthos known as mudrock, on which abundant algal communities …

Adaptive Prediction Emerges Over Short Evolutionary Time Scales., Adrián López García De Lomana, Amardeep Kaur, Serdar Turkarslan, Karlyn D Beer, Fred D Mast, Jennifer J Smith, John D Aitchison, Nitin S Baliga

Articles, Abstracts, and Reports

Adaptive prediction is a capability of diverse organisms, including microbes, to sense a cue and prepare in advance to deal with a future environmental challenge. Here, we investigated the timeframe over which adaptive prediction emerges when an organism encounters an environment with novel structure. We subjected yeast to laboratory evolution in a novel environment with repetitive, coupled exposures to a neutral chemical cue (caffeine), followed by a sublethal dose of a toxin (5-FOA), with an interspersed requirement for uracil prototrophy to counter-select mutants that gained constitutive 5-FOA resistance. We demonstrate the remarkable ability of yeast to internalize a novel environmental …

Anti-Microbial Effects Of Conductive Copper Nanoparticle Film, Daniel Parrott, Kevin M. Ringelman, Michael S. Chaussee

Faculty Publications

Novel infection control methods are needed to prevent further increases in the morbidity and mortality associated with hospital acquired infections. One method is to minimize bacterial transmission is to prevent bacterial growth on hospital surfaces. Copper has anti-microbial properties but is used sparingly in health care settings due to the cost associated with retrofitting surfaces with copper sheet metal or less durable foil. However, copper nanoparticles (CNPs) embedded in a polymer matrix may be similarly anti-microbial, which would offer a viable alternative to copper metal. In this pilot study, we created films with various densities of CNPs and tested their …

Transitional Healthcare Coordination In New York City Jails Among People With Chronic Health Conditions: Contributions To Reduced Reincarceration And Improved Health, Janet J. Wiersema

Dissertations and Theses

People in correctional settings often have poorer health than the general US population. For example, it is estimated that 27.9% of persons in jail have hypertension, 8.1% have diabetes, and 1.6% have HIV, compared to 25.6%, 6.5%, and 0.5%, respectively, in the general population. Jail and other correctional settings are also increasingly recognized as viable places to engage poor and underserved communities into the healthcare system by offering transitional care coordination services to connect people to healthcare and other services to meet priorities after incarceration. At the same time, recidivism is an issue—over 50% of persons in New York City …

Novel Spectroscopic Tools To Differentiate Drug-Dna Binding Interactions, Fadwa Dhafer Hamad

Masters Theses

DNA-drug interactions play a major role in therapeutics, diagnostics, forensics and imaging. Drugs bind to DNA in several ways based on the mode of interaction and they alter protein-DNA interactions or breaks/cleaves DNA that can lead to the cure of the disease. The major goal of the research carried out in this thesis is to develop novel optical spectroscopic tools that can differentiate Drug-DNA binding interactions mode whether its intercalation or minor-groove binding. To achieve this goal, we developed two-photon absorption (2PA) cross-section based technique to differentiate between Drug-DNA binding modes. The investigations were carried out on two drug molecules, …

Spatial Analysis Of Time Between Two Consecutive Dental And Two Consecutive Well-Child Visits For Foster Care Youth, Chenyang Shi

Dissertations

Foster care youth is a medically vulnerable population. Poor dental health and irregular well-child visits may cause serious health-related issues, such as mental disorder, nutrition imbalance, tooth damage, etc. Michigan requires all youth in foster care to receive annual dental and well-child visits. Usually, the study of foster care well-child and dental visits include two parts: time between two consecutive visits (gap time) and number of visits. For this study, a longitudinal-spatial model that has the flexibility to analyze the well-child/dental gap times and number of visits was developed. The longitudinal data (2009-2012) on Michigan foster care youth from 10 …

Chronic Inflammatory Diseases And Green Tea Polyphenols, Helieh S. Oz

Physiology Faculty Publications

Chronic inflammatory diseases affect millions of people globally and the incidence rate is on the rise. While inflammation contributes to the tissue healing process, chronic inflammation can lead to life-long debilitation and loss of tissue function and organ failure. Chronic inflammatory diseases include hepatic, gastrointestinal and neurodegenerative complications which can lead to malignancy. Despite the millennial advancements in diagnostic and therapeutic modalities, there remains no effective cure for patients who suffer from inflammatory diseases. Therefore, patients seek alternatives and complementary agents as adjunct therapies to relieve symptoms and possibly to prevent consequences of inflammation. It is well known that green …

Anthrax, Matrix Biology, And Angiogenesis: Capillary Morphogenesis Gene 2 Mediates Activity And Uptake Of Type Iv Collagen-Derived Anti-Angiogenic Peptides, Jordan Grant Finnell

Theses and Dissertations

Capillary Morphogenesis Gene 2 (CMG2) is a type I transmembrane, integrin-like receptor. It was originally identified as one of several genes upregulated during capillary formation. It was subsequently identified as one of two physiological anthrax toxin receptors, where CMG2 serves as a cell-surface receptor for anthrax toxin and mediates entry of the toxin into cells via clathrin-dependent endocytosis. Additionally, loss-of-function mutations in CMG2 cause the genetic disorder hyaline fibromatosis syndrome (HFS), where the core symptom is dysregulation of extracellular matrix homeostasis (ECM), including excessive accumulation of proteinaceous hyaline material; HFS clearly indicates that CMG2 plays an essential function in ECM …

Comparison Of Cytokine Expression And Bacterial Growth During Periparturient And Mid Lactation Mastitis In A Mouse Model, Rhonda Nicole Chronis

Theses and Dissertations

Clinical cases of bovine mastitis are most severe in the early stages of lactation. The causes of this increased propensity for severe mastitis during early lactation, compared to mid and late lactation are unclear. In order to better understand the early lactation immune response to mastitis, a murine model of mastitis was employed. Intramammary inoculation of a mastitis causing Escherichia coli strain was performed in lactating mice at various stages of lactation to model the immune response seen in cows during lactation. In our experiments, mice in the early stages of lactation exhibited altered mRNA expression of cytokines IL-1β, IL-6, …

Macpherson, Pradoldej Sompol, George T. Kannarkat, Jianjun Chang, Lindsey Sniffen, Mary E. Wildner, Christopher M. Norris, Malú G. Tansey

Sanders-Brown Center on Aging Faculty Publications

Clinical and animal model studies have implicated inflammation and peripheral immune cell responses in the pathophysiology of Alzheimer’s disease (AD). Peripheral immune cells including T cells circulate in the cerebrospinal fluid (CSF) of healthy adults and are found in the brains of AD patients and AD rodent models. Blocking entry of peripheral macrophages into the CNS was reported to increase amyloid burden in an AD mouse model. To assess inflammation in the 5xFAD (Tg) mouse model, we first quantified central and immune cell profiles in the deep cervical lymph nodes and spleen. In the brains of Tg mice, activated (MHCII …

Federalism And Health Care In Canada: A Troubled Romance?, University Of Ottawa Law Rps Submitter, Colleen M. M. Flood, Bryan P. Thomas, William Lahey
