From reader of issue 3:

"This is a fascinating read - thank you PAPAA for putting out this excellent brief paper! I certainly identified with the article 'In sickness and in health'. As we know, Psoriasis can cause so much stress and anxiety. Also, I have tried Dead Sea Salts at home, but didn't see any improvement in my skin. I wonder if it makes a difference if you visit the area and take the salts there? Exciting news about the Sotyktu drug!"
