There are about 1 clinical studies being (or have been) conducted in Antarctica. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
There is evidence to indicate that the gut microbiota has an effect on mental well-being and stress behaviours. This is highly relevant to both life on earth and spaceflight missions, in which mental well-being is crucial to mission success. Bifidobacterium longum 1714 (BL 1714), will be tested in the project ICELAND-2 in a double-blind, randomized placebo-controlled pilot study in crew members of the Antarctica station CONCORDIA in order to test stress resilience and possible outcomes on the immune system since the metabolic stress response and the immune system are closely interrelated. Crew members of CONCORDIA station have a prolonged stay (roughly 12 months) in a confined (antigen exposure restricted, overclean) and isolated environment, mimicking the situation of long-term space travel. ICELAND-2 will be conducted over three consecutive winter-over periods (3 years). The project ICELAND-2: 1. evaluates the effect of the probiotic BL1714 on well-being regarding mood, social integration and stress and other parameters . 2. determines the effect of an antigen-limited environment like Concordia on gut microbiota, immune system and epigenetics. 3. examines the interaction between the factors mentioned in 1. 4. examines the role of nutrition intake and behaviour in the interplay mentioned above.
