450 kilometers above the earth: medicine in space

What happens to the human body when it leaves Earth? What does weightlessness do to the body? In space, medicine faces completely new challenges as to how these changes can be recorded and what significance this has for applications on Earth. And this was precisely the topic of an international workshop at the LMU Klinikum München.

The three-day workshop was the start of an intensified research collaboration between the LMU Clinic, the National Research Council (NRC) and universities in Québec and Ontario, Belgium and Germany. Prof. Dr. Alexander Choukér, Dr. Dominique Moser and Marina Tuschen from the Department of Anaesthesiology organized the Bavarian-NRC-funded workshop together with Prof. Dr. Teodor Veres from Montréal. The aim is to use so-called microfluidic chips to make it easier and more reliable to monitor various human organ systems as well as life support systems (e.g. water treatment). The project has been funded by the German Aerospace Center (DLR) for three years and has received start-up funding from the Bavarian Research Alliance (BayFOR).

Space research for the medicine of tomorrow

Weightlessness changes the human body profoundly: body fluids shift to the upper body, which in turn has an impact on the brain and the cardiovascular system also has to reorganize itself. These processes increase the risk of blood clots, not in the legs as in humans on Earth, but in the necks of astronauts - an aspect that has been neglected for far too long in space research.

"Research into these processes is not only important for space travel, but can also provide insights for people on Earth, for example in cases of immobility or perioperatively," says PD Dr. Judith-Irina Buchheim, project manager of current ISS projects, who addressed this in one of the sessions and described the importance of the immune system. There is already research on this, for example on brown bears in hibernation or on humans in extreme living conditions. However, further studies in space would be enormously important in order to bring together these cross-organ findings.

"The workshop is an important part of our collaboration," says organizer Prof. Dr. Alexander Choukér, who heads the Research Laboratory I "Translational Research Stress and Immune System" at the Department of Anaesthesiology at LMU Hospital. "Lively debates and short interdisciplinary keynote speeches alternated here, which included important aspects of biology (represented by Dean Prof. Herwig Stibor) and engineering (Prof. Gisela Detrell, TUM) in addition to medical topics."

The space agencies from Canada, Germany (DLR) and Europe (ESA) were also represented with presentations on current programs. The collaboration is to be expanded further. A scientific consortium is currently being planned to help implement EU applications.
