The shape of psychotrauma?

Is this shape (below) psychotraumatically symbolic?

The dramatically named Argentine Society for Psychotrauma lists the topics to be discussed at the International Congress on Traumatic Stress and Anxiety Disorders. The Society is organizing this event, which will occur June 23-25 in Buenos Aires. The Society’s web site lists the topics to be discussed. As you can see here, they chose to format that list in the shape of a nail. The web site does not discuss the symbolism, if any, of this shape for that conference.
