Insights from serological surveillance in infectious disease epidemiology
Traditional infectious disease surveillance methods rely on testing of symptomatic individuals. However, such methods are often poor indicators of the true burden of infection in a population due to varying rates of subclinical infections, non-specific symptoms, and heterogeneity in health seeking …

Studying glomerular disease epidemiology: tackling challenges and paving a path forward
Background: Glomerular diseases are a group of rare immune-mediated kidney diseases that affect the glomeruli, or filtering units, of the kidney. Major knowledge gaps remain in our understanding of glomerular disease epidemiology. Efforts to describe glomerular disease distributions based on …

The Politics of Operationalizing the World Health Organization Activities: Global Politics, Health Security and the Global Outbreak Alert and Response Network
Infectious diseases attract a lot of mediatic, cultural and political attention. But are those diseases like Ebola, or ‘disease x’ actually what kills us? Since 1946, the WHO is the most authoritative figure in the fights against infectious disease outbreaks. So how does the WHO maintain this power …

Methodological focus and application of exploratory dietary patterns in epidemiological research
… on health is an important piece of chronic disease epidemiology, but many challenges arise when attempting to adequately measure and account for complete dietary exposure. The exploratory approach to dietary patterns is a useful method that utilizes multivariate data reduction techniques to …

Investigating kidney disease clinical epidemiology using routinely collected administrative data and proteomics
… are invaluable to better understand kidney disease epidemiology. This thesis explores the detection and characterization of acute kidney injury (AKI), chronic kidney disease (CKD), acute-on-chronic kidney disease (A-on-CKD) and kidney disease progression using rule-based laboratory- and …

Fitting Stochastic Epidemic Models to Multiple Data Types
Traditional infectious disease epidemiology focuses on fitting deterministic and stochastic epidemics models to surveillance case count data. Recently, researchers began to make use of infectious disease agent genetic data to complement statistical analyses of case count data. Such genetic analyses …

Standard echocardiography versus handheld echocardiography for the detection of subclinical rheumatic heart disease: A systematic review
Rheumatic heart disease (RHD) is a permanent heart valve condition resulting from an abnormal immune reaction to group A streptococcal (GAS) infection typically occurring in childhood. If left untreated, disease progression can result in irreversible heart valve damage, cardiac failure, stroke and …

Characterization of Pyrenophora Tritici-Repentis in Wheat and Rye to Study Tan Spot Susceptibility and Insights Into Its Relationship with Stem Rust Resistance
… tritici-repentis (Ptr), is a major foliar fungal disease of wheat worldwide. To date, Ptr isolates have been grouped into eight races based on the production of three host selective effectors (toxins), Ptr ToxA, ToxB, and ToxC, which are associated with necrosis and chlorosis symptoms on wheat …

Sindromi drepanocitiche: studio di fattibilità di strategie di prevenzione e rimodellamento della rete assistenziale in un contesto in evoluzione
Sickle cell disease (SCD) is the first genetic disease in the world and remains largely ignored by the population but also by health professionals. SCD is characterized by a variable clinical expression; however most of the patients are at risk to develop acute and severe complications conducting …
