Cost‐effectiveness of treating vascular leg ulcers with UrgoStart® and UrgoCell® Contact

International Wound Journal, Volume 13, Issue 1, Page 82-87, February 2016., 2016
Abstract Although chronic wounds have a high socio‐economic impact, data on comparative effectiveness of treatments are rare. UrgoStart® is a hydroactive dressing containing a nano‐oligosaccharide factor (NOSF). This study aimed at evaluating the cost‐effectiveness of this NOSF‐containing wound dressing in vascular leg ulcers compared with a similar ...

A closer examination of atraumatic dressings for optimal healing

International Wound Journal, Volume 12, Issue 5, Page 510-516, October 2015., 2015
Abstract The concept that undisturbed wound healing, optimised by dressing choice, improves wound outcomes has become a focal point of consideration when evaluating wound management regimens in recent years. However, little evidence exists related to wound contact layers and the potential detrimental effects of the intimate contact with the wound bed ...

When proteases reshape barriers: Basement membrane remodelling in development, wound healing and tumour progression

The FEBS Journal, Volume 293, Issue 13, Page 3954-3972, July 2026.
Basement membrane (BM) homeostasis relies on a balance between integrity, controlled remodelling and pathological degradation. Increased protease expression beneath the BM, along with reduced levels of endogenous protease inhibitors, drives the transition from a continuous, protective barrier to a discontinuous interface.
