The impact of measures to remedy certain medical risk factors has been clearly demonstrated. Specific programs can improve functional status, avoid institutionalization, and perhaps prolong survival.

In addition, splenic immunity, which associates specific and nonspecific humoral and cellular effector mechanisms is no longer a question of debate.
