fernab, at this time, I only know what you know, that the researchers (and NORD) have decided to look into “autonomic, endocrine, and immune mediators of POIS”. The 2 players (NORD and the investigators) really call the research, methodology and implementation shots. But I can tell you that - based on my interactions with them thus far - they are very empathetic to our suffering and will try hard to help us within our very modest research budget. I sense flexibility.
In that vein, I hope they can or will consider requests just as you have now made.
