CTRL+S the BPH podcast to understand, prevent and care

Retour

 

CTRL+S, is the new podcast produced by Bordeaux Population Health (University of Bordeaux/Inserm) to better understand the world of public health research through interviews accessible to everyone. We discuss key public health issues resulting from the wide variety of topics we study at BPH

 

 

 

 

 

 

The title, “CTRL+S”, corresponds to the keyboard command for saving. But here, it’s information and trustworthy knowledge directly from the work of researchers that we want to preserve. What’s more, the “S” is a reference to public health in french “Santé publique”. Finally, the episodes are structured around the BPH’s motto: “understand, prevent and care”, so it was only natural that we chose it as our slogan.

 

 

In each episode, researchers from the BPH and other partners are given the opportunity to discuss, in less than 20 minutes, concepts that are sometimes unclear but which we are all increasingly confronted with: AI, mental health, pandemics, etc.

Episode 2

Episode 2:
The eye and brain in relation to time, the environment and lifestyle

In recent years, we have seen an epidemic of myopia, while age-related eye diseases remain very common: AMD affects one in five people over the age of 75, and glaucoma affects one in ten people over the age of 40.

In this second episode, we seek to understand how our lifestyle and environment can influence the development of eye diseases or, conversely, help to prevent them. We also explore the role of the brain and ageing in these mechanisms.

This episode is essential for gaining a better understanding of recent discoveries from epidemiological population studies, as well as how these studies are conducted.
To address these multiple environmental exposures, we brought together three epidemiologists from the LEHA team, each with complementary expertise:

■ Bénédicte Merle – Inserm researcher, specialist in the role of lifestyle and nutrition on eye health. She has worked in particular on the impact of certain nutrients on eye health, highlighting the importance of a diet that limits the risk of developing AMD.

■ Catherine Helmer – Inserm Research Director. Through her work on brain ageing and cognitive health, she explores the links between brain diseases and eye diseases.

■ Laure Gayraud – Young researcher, during her work on the impact of air pollution on eye health, she explains how greater exposure to air pollution could increase the risk of retinal degeneration.

To be reviewed

Episode 1:
New technologies – prevention or danger?

Mental health is an important part of public health issues. In 2025, it even became a priority research topic at the national level.

At the same time, digital technologies are playing an increasingly important role in our lives and in research. We hear about artificial intelligence every day, generating as much enthusiasm as concern.

 

 

This very first episode of CTRL+S explores the link between these two themes, featuring three researchers with complementary perspectives:

 

        • Melissa Macalli – Epidemiologist, Inserm researcher within the Healthy-BPH team. Her work focuses on student mental health in the digital era, particularly through projects such as the Lab Santé Étudiante.

 

        • Marie Navarro – She was a PhD student in the Healthy-BPH team and now she is a postdoctoral researcher at the University of Groningen (Netherlands), where she continues her research on predicting suicide risk using machine learning, a sub-branch of artificial intelligence.

 

        • Hélène Sauzéon – Professor of psychology and cognitive science, member of the SISTM-BPH team and Inria. She develops projects using augmented reality to prevent certain psychological disorders and support elderly people who are losing their independence.

 

 

At BPH, we are committed to promoting the work of young people to prepare a promising new generation. That is why this podcast was produced entirely by a second-year Master’s student in Science and Technology Mediation and Communication at Bordeaux Montaigne University, as part of her end-of-studies internship in the BPH’s communications department.
