How do pre-existing conditions such as heart failure, respiratory disease, and diabetes affect the skin's healing capabilities in older adults?

They compromise the blood supply and healing capabilities of the skin

What is the effect of trauma to the skin on older adults with minimal adipose layer?

It is more likely to lead to bruising and will be more painful
