Summer Course 2019
32nd Residential Summer Course in Epidemiology
1 July – 5 July 2019
|Week 3, parallel morning module 1
|Advanced statistical topics
|Per Kragh Andersen with Corrado Lagazio and Michaela Baccini
|Week 3, parallel morning module 2
|Causal methods in epidemiology:
Mendelian randomization and triangulation
|Debbie Lawlor and Carolina Borges|
|One of the key uses of epidemiology is to identify causes of disease and health related behaviours in populations. This is necessary to provide the evidence base for prevention and treatment targets for which interventions can be developed and their effectiveness tested. Mendelian randomization (MR) is a relatively new method for exploring causality in observational studies. It refers to the use of genetic variants as instrumental variables to understand causal effects of non-genetic modifiable risk factors (including ‘physiological’ risk factors such as blood pressure, fasting glucose, CRP and lifestyle risk factors such as smoking, caffeine consumption and alcohol intake). It is a method that is increasingly used in epidemiology. Other approaches to causal inference, including cross-cohort comparisons, negative control studies, and matching designs such as within sibship analyses are also increasingly used. By the end of this module students should be able to:
The course will use a mix of lectures, computer exercises and small group practicals.
There is no requirement to understand genetics (we will provide a brief background about genes to the level needed for their use in MR), but students should have a good grounding in the principles of epidemiology, including a clear understanding of confounding and the assumptions of multivariable regression analyses.

|From epidemiology to the burden of disease: putting risks in perspective|
|Nino Künzli and Thomas Fürst
Epidemiology is a core science to investigate and quantify the association between risk factors and health outcomes. However, public health professionals and policy makers need to understand the public health relevance of risks to plan and prioritize prevention and policy making. The epidemiology-based assessment of the risk related burden of disease provides the bridge between public health science and policy. This course will familiarize students with the use of epidemiology in quantitative risk assessment and the comparison across risks. Based on a range of examples, students will i) learn how epidemiology contributes to quantitative risk assessment, ii) understand the tools to assess the health burden and iii) critically interpret the derived outputs. Exercises based on the burden of disease data will train critical thinking for the comparison of different public health risks.
Approach: Lectures on concepts, self-studies with on-line exercises and group discussions will foster the understanding of how epidemiology is used in risk assessment. Students are expected to bring their personal note books to independently work on line, on the web.
|Week 3, parallel afternoon module 1
|Clinical Epidemiology: the evaluation of medical tests
|Patrick M Bossuyt
In this one-week course, we focus on three topics:
Diagnostic testing: Diagnostic accuracy, bias and study design in diagnostic testing.
Prognostic modeling: The concept of a prognostic model, building and testing the validity of a model, interpreting data from prognostic models.
Intervention study design: Introduction to RCTs and innovative design, comparison between RCT and observational studies, confounding by indication.
Approach: A combination of lectures and personal assignments, to be completed in pairs and discussed in the group.
|Week 3, parallel afternoon module 2
|Advanced topics in epidemiology|
|Irene Petersen and Jan Vandenbroucke
The origins and usefulness of several advance study desings and methods of analyses will be studied – each time ending with a current positioning: what is state-of-the art and what are the potential applications and pitfalls (with practical examples)
|Week 3, parallel afternoon module 3
|Principles of prevention in the precision medicine and Big data era|
This module presents to researchers, health professionals and clinicians particularly interested in prevention a perspective critically examining whether the population and the individualized approaches, as a classically outlined by Geoffrey Rose in the 1980s, still represent useful concepts and operational principles or whether the availability of massive health data on each person makes them obsolete leading to a unified ‘precision prevention’ approach. Relevant methodological aspects will be reviewed, involving an introductory presentation of causal versus predictive models and of machine learning instruments. Specific ethical issues that prevention research and measures raise will be sketched for discussion.
Approach: lectures, reading of papers with critical discussion and ‘pros and cons’ arguments.
|Week 3, parallel afternoon module 4
|Infectious disease epidemiology|
|Tyra Grove Krause and Steen Ethelberg
Vaccines, antibiotics and hygiene measures have played an important role in the fight against infectious diseases. However, worldwide inequalities in accessing health care including treatments and vaccines, re-emergence of vaccine preventable diseases, and the threat of antimicrobial resistance as well as the risk of emerging new pathogens underline the fact that infectious diseases remain a global public health challenge.
This course will introduce the epidemiological fields of transmissibility, vaccinology, disease surveillance and outbreak investigations. By the end of this module, the student should be able to understand:
The course will use a mix of lectures and small group case studies.
Prior knowledge of infectious diseases is not needed but students should have a good understanding of principles of epidemiology, including a basic knowledge of measures of frequency and associations and epidemiological study designs.
