Risk Factors Of Diarrhea In Children Under 5 Years In Al-Mukalla, Yemen, Ali S. Bahartha, Jalil I. Alezzi

Saudi Medical Journal

Objectives: To assess the risk factors associated with diarrhea among children below 5-years-old in Mukalla, Yemen, and compare with other studies. Methods: We conducted a case-control study on 200 children (100 cases and 100 controls) who attended the Maternity and Child Hospital, outpatient-clinics, and the Primary Health Care Centers in Al-Mukalla, Hadhramout, Yemen between February and April 2013. Results: We found that the significant risk factors associated with diarrhea were crowded housing (odds ratio [OR] 2.02; p =0.02; confidence interval [CI] 1.03-4.01), incomplete vaccination of the child (OR=2.02; p =0.027; CI: 1.08-3.8), and recurrent diarrheal illness during the last 3 …

Fecal Volatile Organic Ccompound Profiles From White-Tailed Deer (Odocoileus Virginianus) As Indicators Of Mycobacterium Bovis Exposure Or Mycobacterium Bovis Bacille Calmette-Guerin (Bcg) Vaccination, Randal S. Stahl, Christine K. Ellis, Pauline Nol, W. Ray Waters, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

White-tailed deer (Odocoileus virginianus) serve as a reservoir for bovine tuberculosis, caused by Mycobacterium bovis, and can be a source of infection in cattle. Vaccination with M. bovis Bacille Calmette Guerin (BCG) is being considered for management of bovine tuberculosis in deer. Presently, no method exists to non-invasively monitor the presence of bovine tuberculosis in deer. In this study, volatile organic compound profiles of BCG-vaccinated and non-vaccinated deer, before and after experimental challenge with M. bovis strain 95–1315, were generated using solid phase microextraction fiber head-space sampling over suspended fecal pellets with analysis by gas chromatography/mass spectrometry. …

Isolation And Epidemiological Analysis Of Verotoxigenic E. Coli From Patients With Acute Gastroenteritis: A Prospective Study Aiming To Reduce The Burden Of Infection In The Cork Region., Shirley Ross

Masters

Verotoxigenic Escherichia coli (VTEC) is a serious gastrointestinal pathogen associated with morbidity and mortality in the first world, as accentuated by the O104 VTEC outbreak in Germany in 2011. Molecular detection of Verotoxin (VT) has increased the detection of VTEC across Europe however, Ireland still has the highest incidence and isolation is still a key step in the confirmation of infection and the control and prevention of outbreaks. Currently no standard protocol exists for the detection, isolation and characterisation of non-O157 VTEC and it is feared that due to this that the prevalence of VTEC is under-reported. This body of …

Examining Critical Race Theory: Outsider Jurisprudence And Hiv/Aids - A Perspective On Desire And Power, Shannon Gilreath

Symposium: Examining Critical Race Theory: Honoring Professor Richard Delgado

West Nile Virus And Ferruginous Hawks (Buteo Regalis) In The Northern Great Plains, Shubham Datta, Jonathan A. Jenks, David E. Knudsen, Kent C. Jensen, Will M. Inselman, Christopher C. Swanson, Troy W. Grovenburg

The Prairie Naturalist

Emerging infectious diseases (EID) present significant threats to the conservation of global biodiversity (Daszak et al. 2000). Evaluating impacts (spatial, temporal and demographic) of EIDs on sensitive and declining wildlife populations is challenging because quantitative information is usually dependent on estimates rather than counts (Wobeser 2007) and mortality rates are seldom quantified with conventional monitoring (Naugle et al. 2005).

West Nile virus (WNv), a mosquito-borne Flavivirus (family Flaviviridae; Komar 2001), was discovered in northwest Uganda in 1937 (Smithburn et al. 1940). First encountered in the western hemisphere in New York in 1999 (Nash et al. 2001), WNv has become enzootic …

Evaluation Of Vaccination Policies Among Utah Pediatric Clinic Employees, Karlen Beth Luthy, Tia Peterson, Janelle L B Macintosh, Lacey M. Eden, Renea L. Beckstrand, Nathan H. Wiley

Faculty Publications

Introduction: Pediatric health care settings are high risk environments for spreading communicable and vaccine-preventable diseases from health care workers to susceptible patients. Method: All managers of pediatric clinics operating in the state of Utah were included. Participants were invited to complete a two-page questionnaire regarding their clinic vaccination policies. Results: Half (n = 23, 50%) of Utah pediatric outpatient clinic managers recommend employee vaccinations, although employee refusal was allowed without consequence. Of all adult vaccines, influenza was most often included by managers as part of the employee vaccination policy. Some managers required unvaccinated employees to wear masks in the event …

Physiological Factors Affecting The Bactericidal Activity Of The Western Fence Lizard (Sceloporus Occidentalis) For The Lyme Disease Spirochete, Borrelia Burgdorferi, Kyle Russell Weichert

Master's Theses

The Western Fence Lizard (Sceloporus occidentalis) is a major host of juvenile stages of the Western Black-legged Tick (Ixodes pacificus), which is the vector for the Lyme disease causative spirochete bacterium Borrelia burgdorferi in the western United States. Because S. occidentalis is reservoir incompetent and capable of eliminating spirochetes from infected ticks, it has been implicated as a major factor in the ecology of Lyme disease in the West. Although complement proteins in lizard blood have been established as the borreliacidal factor, no studies have examined intraspecific variability in host lizard borreliacidal capacity. In Chapter 1 …

Background: Artemether-lumefantrine is the most widely used artemisinin-based combination therapy for malaria, although treatment failures occur in some regions. We investigated the effect of dosing strategy on efficacy in a pooled analysis from trials done in a wide range of malaria-endemic settings. Methods: We searched PubMed for clinical trials that enrolled and treated patients with artemether-lumefantrine and were published from 1960 to December, 2012. We merged individual patient data from these trials by use of standardised methods. The primary endpoint was the PCR-adjusted risk of Plasmodium falciparum recrudescence by day 28. Secondary endpoints consisted of the PCR-adjusted risk of P …

Depression As Sickness Behavior? A Test Of The Host Defense Hypothesis In A High Pathogen Population, Jonathan Stieglitz, Benjamin C. Trumble, Melissa Emery Thompson, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Sadness is an emotion universally recognized across cultures, suggesting it plays an important functional role in regulating human behavior. Numerous adaptive explanations of persistent sadness interfering with daily functioning (hereafter “depression”) have been proposed, but most do not explain frequent bidirectional associations between depression and greater immune activation. Here we test several predictions of the host defense hypothesis, which posits that depression is part of a broader coordinated evolved response to infection or tissue injury (i.e. “sickness behavior”) that promotes energy conservation and reallocation to facilitate immune activation. In a high pathogen population of lean and relatively egalitarian Bolivian foragerhorticulturalists, …

World Sepsis Day In Pakistan, Madiha Hashmi

Department of Anaesthesia

Celebration of World Sepsis Day at a global level started just three years back, and the immense importance of this celebration was not lost to Pakistan Society of Anaesthesiologists (PSA) and Pakistan Society of Critical Care Medicine (PSCCM). Both these organizations were quick to grasp the opportunity to use it to achieve the common goal of enhancing the level of awareness about sepsis and prevention of sepsis among the healthcare professionals as well as higher authorities. The result was multiple international academic events being organized regularly across the country as well as the adoption of National Sepsis Guidelines. The struggle …

Identifying The Molecular Mechanisms Of Early Cachexia Using Whole Transcriptome Sequencing In Muscle And Fat Biopsies From Cancer Patients, Amal Hussain Al Hadad

Dissertations

Cancer cachexia is responsible for one third of cancer–related deaths and contributes to the death of many others. More than 80% of cancer patients are cachectic towards the end of life. Despite intensive research, the mechanisms of cancer cachexia are still poorly understood. It is our hypothesis that identification of early changes in gene expression in cachexia will lead to an improved understanding of the mechanism that trigger this important problem in cancer patients. Thus, to shed light on the mechanisms involved in the major cachexia target tissues, we investigated the entire transcriptome in muscle and fat to identify altered …

Spatial Heterogeneity, Host Movement And Mosquito-Borne Disease Transmission, Miguel A. Acevedo, Olivia Prosper, Kenneth Lopiano, Nick Ruktanonchai, T. Trevor Caughlin, Maia Martcheva, Craig W. Osenberg, David L. Smith

Dartmouth Scholarship

Mosquito-borne diseases are a global health priority disproportionately affecting low-income populations in tropical and sub-tropical countries. These pathogens live in mosquitoes and hosts that interact in spatially heterogeneous environments where hosts move between regions of varying transmission intensity. Although there is increasing interest in the implications of spatial processes for mosquito-borne disease dynamics, most of our understanding derives from models that assume spatially homogeneous transmission. Spatial variation in contact rates can influence transmission and the risk of epidemics, yet the interaction between spatial heterogeneity and movement of hosts remains relatively unexplored. Here we explore, analytically and through numerical simulations, how …

Bounded Rationality Alters The Dynamics Of Paediatric Immunization Acceptance, Tamer Oraby, Chris T. Bauch

School of Mathematical & Statistical Sciences Faculty Publications

Interactions between disease dynamics and vaccinating behavior have been explored in many coupled behavior-disease models. Cognitive effects such as risk perception, framing, and subjective probabilities of adverse events can be important determinants of the vaccinating behaviour, and represent departures from the pure “rational” decision model that are often described as “bounded rationality”. However, the impact of such cognitive effects in the context of paediatric infectious disease vaccines has received relatively little attention. Here, we develop a disease-behavior model that accounts for bounded rationality through prospect theory. We analyze the model and compare its predictions to a reduced model that lacks …

The English Channel: Contamination Status Of Its Transitional And Coastal Waters, Ad Tappin, Ge Millward

School of Geography, Earth and Environmental Sciences

The chemical contamination (organic compounds, metals, radionuclides, microplastics, nutrients) of English Channel waters has been reviewed, focussing on the sources, concentrations and impacts. River loads were only reliable for Pb, whereas atmospheric loads appeared robust for Cd, Pb, Hg, PCB-153 and γ-HCH. Temporal trends in atmospheric inputs were decreasing. Contaminant concentrations in biota were relatively constant or decreasing, but not for Cd, Hg and HBCDD, and deleterious impacts on fish and copepods were reported. However, data on ecotoxicological effects were generally sparse for legacy and emerging contaminants. Intercomparison of activity concentrations of artificial radionuclides in sediments and biota on both …

Designing Novel Abstraction Networks For Ontology Summarization And Quality Assurance, Christopher Ochs

Dissertations

Biomedical ontologies are complex knowledge representation systems. Biomedical ontologies support interdisciplinary research, interoperability of medical systems, and Electronic Healthcare Record (EHR) encoding. Ontologies represent knowledge using concepts (entities) linked by relationships. Ontologies may contain hundreds of thousands of concepts and millions of relationships. For users, the size and complexity of ontologies make it difficult to comprehend “the big picture” of an ontology's content. For ontology editors, size and complexity make it difficult to uncover errors and inconsistencies. Errors in an ontology will ultimately affect applications that utilize the ontology.

In prior studies abstraction networks (AbNs) were developed to provide a …

Surf-N-Turf, But The Sustainable Kind? The Limits And Potential Of Market-Driven Regulation In Food Production, Zdravka Tzankova, Lauren Gwin

Seattle Journal of Environmental Law

This article examines the dynamics and likely effects of NGO efforts at private, market-driven regulation of antibiotics use in US agricul-ture. Such NGO efforts aim to eliminate the routine feeding of anti-biotics to healthy animals for the purposes of prophylaxis and growth promotion. To that end, NGOs are pressing large food retailers, who are some of the most powerful market actors, to demand antibiotic-free meat and to refuse selling meat produced with sub-therapeutic use of antibiotics. Curbing agricultural overuse of antibiotics is critically important for public health because overuse erodes the curative power of antibiot-ics by creating antibiotic resistant animal …

Comparison Of Cardiovascular Risk Profiles Amongst Newly Diagnosed Cancer Patients And Non-Cancer Patients At The Aga Khan University Hospital Nairobi, Majid Lingani-Ncube Sikosana

Master of Medicine in Internal Medicine

Background: Non-Communicable Diseases (NCDs) are fast becoming the leading causes of morbidity and mortality in Low and Middle-income countries (LMIC) with cancers and cardiovascular diseases (CVDs) becoming the most prominent. CVD can be prevented if appropriate measures of screening and treatment of modifiable risk factors are addressed. This may translate to reduced risk of CVDs and some cancers in the long term. Increasing evidence exhibits common risk factors for both CVDs and cancer and that CVDs and their risk factors when present in cancer patients may worsen the overall outcome. Objectives: The primary objective was to determine and compare the …

Homelessness As A Determinant Of Health Disparities Between Young Gay And Bisexual Males In Chicago, Jaclyn M. Shea, Douglas Bruce

DePaul Discoveries

There is limited research documenting health disparities between gay and bisexual males. This study aimed to examine the health behaviors and outcomes of young gay and bisexual males in Chicago, including substance use, mental health, and homelessness. Data was from a cross-sectional survey of 180 bisexual and gay males age 16-24. Bivariate results indicate that bisexual males experience higher rates of homelessness, daily marijuana use, depressive symptoms, lifetime gonorrhea and chlamydia. Logistic regression results reveal homelessness was significantly associated with marijuana use, gonorrhea, chlamydia, and depressive symptoms. Research on disparities within sexual minorities and homelessness are needed to better understand …

Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane

DePaul Discoveries

Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide^5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma⁷. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of …

Modeling The Geographic Spread Of Rabies In China, Jing Chen, Lan Zou, Shigui Ruan

Mathematics Faculty Articles

Abstract

In order to investigate how the movement of dogs affects the geographically inter-provincial spread of rabies in Mainland China, we propose a multi-patch model to describe the transmission dynamics of rabies between dogs and humans, in which each province is regarded as a patch. In each patch the submodel consists of susceptible, exposed, infectious, and vaccinated subpopulations of both dogs and humans and describes the spread of rabies among dogs and from infectious dogs to humans. The existence of the disease-free equilibrium is discussed, the basic reproduction number is calculated, and the effect of moving rates of dogs between …

Isolation Of Mycobacterium Avium From Potable Water In Homes And Institutions Of Patients With Hiv Infection In Finland And The United States, Matti Ristola, Robert D. Arbeit, C. Fordham Von Reyn, C. Robert Horsburgh

Dartmouth Scholarship

Symptomatic disease by nontuberculous mycobacteria has been linked to potable water from institutional and domestic potable water systems. Potable water samples were collected from homes and institutions of patients with AIDS. Colonization of potable water with nontuberculous mycobacteria was demonstrated in 230 (15%) of 1489 samples collected from domestic and institutional water systems of patients with HIV infection in the United States and Finland. Mycobacterium avium was the most common species and colonization was favored at temperatures of 40–50°C in recirculating hot water systems. Such systems are a plausible source of human infection and disease.

The Role Of Damage-Associated Molecular Patterns (Damps) In Human Diseases : Part Ii: Damps As Diagnostics, Prognostics And Therapeutics In Clinical Medicine, Walter G. Land

Sultan Qaboos University Medical Journal

This article is the second part of a review that addresses the role of damage-associated molecular patterns (DAMPs) in human diseases by presenting examples of traumatic (systemic inflammatory response syndrome), cardiovascular (myocardial infarction), metabolic (type 2 diabetes mellitus), neurodegenerative (Alzheimer’s disease), malignant and infectious diseases. Various DAMPs are involved in the pathogenesis of all these diseases as they activate innate immune machineries including the unfolded protein response and inflammasomes. These subsequently promote sterile autoinflammation accompanied, at least in part, by subsequent adaptive autoimmune processes. This review article discusses the future role of DAMPs in routine practical medicine by highlighting the …

Ebolavirus And Haemorrhagic Syndrome, Gerald A. Matua, Dirk M. Van Der Wal, Rozzano C.

Sultan Qaboos University Medical Journal

The Ebola virus is a highly virulent, single-stranded ribonucleic acid virus which affects both humans and apes and has fast become one of the world’s most feared pathogens. The virus induces acute fever and death, with haemorrhagic syndrome occurring in up to 90% of patients. The known species within the genus Ebolavirus are Bundibugyo, Sudan, Zaïre, Reston and Taï Forest. Although endemic in Africa, Ebola has caused worldwide anxiety due to media hype and concerns about its international spread, including through bioterrorism. The high fatality rate is attributed to unavailability of a standard treatment regimen or vaccine. The disease is …

Increasing Incidence Of Infants With Low Birth Weight In Oman, M Mazharul Islam

Sultan Qaboos University Medical Journal

This review article provides an overview of the levels, trends and some possible explanations for the increasing rate of low birth weight (LBW) infants in Oman. LBW data from national health surveys in Oman, and published reports from Oman’s Ministry of Health and the World Health Organization were collected and assessed between January and August 2014. Oman’s LBW rate has been increasing since the 1980s. It was approximately 4% in 1980 and had nearly doubled (8.1%) by 2000. Since then, it has shown a slow but steady rise, reaching 10% in recent times. High rates of consanguinity, premature births, number …
