Obesity is among today’s most pressing public health concerns and it’s negative impact on the human body—particularly in light of SARS-COV-2 infection, can be devastating. Once gained, losing weight can be difficult, but maintaining weight loss is even more difficult. This author provides evidence-based tips for maintaining lost pounds that you can share with patients and clients.

A crucial component of wound management is regular debridement. The goal of debridement is the removal of all necrotic, fibrous, and devitalized tissue from the wound bed. Devitalized tissue in wounds produces a physical barrier to formation of new tissue and therefore decreases healing rates. If devitalized tissue remains in the wound bed, bacterial colonization is more likely.

Millions of Americans are afflicted with painful, open, draining ulcers on their lower extremities. Venous leg ulcers (VLUs) cause significant clinical and economic burden to the healthcare system and society.1,2 It is not uncommon for clinicians to see patients who have suffered for years with VLUs.
