Decellularized matrices of biologic tissue have performed well as wound care dressings. Extracellular matrix-based dressings are subject to rapid degradation by excessive protease activity at the wound environment. Stabilized, acellular, equine pericardial collagen matrix (sPCM) wound care dressing is flexible cross-linked proteolytic enzyme degradation resistant. sPCM was structurally characterized utilizing scanning electron and atomic force microscopy. In murine excisional wounds, sPCM was effective in mounting an acute inflammatory response...

INTRODUCTION: Mycobacterium smegmatis is a common microbe found in soil, dust, and water that rarely causes infections in humans. CASE REPORT: A 45-year-old man with a past medical history of hypertension presented with a nonhealing surgical wound in his anterior chest wall, measuring 0.5 cm x 0.5 cm x 0.3 cm with minimal serosanguinous drainage, that had been present for more than 1 year. Wound swab showed M smegmatis. He required a 3-month course of antibiotic treatment and advanced wound care that included packing the sinus wounds with silver-alginate dressings for the first 2 weeks followed by iodoform packing; once the infection and drainage had improved after 2 months of treatment, packing was changed to a collagen dressing...

The treatment of skin wounds is a key research domain owing to the important functional and aesthetic role of this tissue. When the skin is impaired, bacteria can soon infiltrate into underlying tissues which can lead to life-threatening infections. Consequently, effective treatments are necessary to deal with such pathological conditions. Recently, wound dressings loaded with antimicrobial agents have emerged as viable options to reduce wound bacterial colonization and infection, in order to improve the healing process...

Hydrogels are 3D hydrophilic polymer networks that absorb and hold huge amounts of water. Although hydrogels have traditionally been synthesized using chemical and physical methods, rapid developments in enzyme technology that, like chemical-based methods, enable the formation of stable covalent bonds are fast emerging as alternative 'green catalyst' tools. Enzymes show great potential for the synthesis of complex multifunctional wound dressing hydrogels (WDHs) ex situ and in situ as well as in acting as interactive molecules to promote the wound healing process...

Despite recent advances in bioengineered therapies, wound healing remains a serious clinical problem. In acute full-thickness wounds, it is desirable to replace both the damaged dermis and epidermis in a single procedure. This approach requires appropriate properties of tissue-engineered dressings to support simultaneous regenerative processes in the dermis and epidermis while they are temporally separated in the natural wound healing process. In this study, a collagen-based scaffold inhabited by skin cells was employed...

Bacterial cellulose (BC) is a promising material for wound dressing due to its predominant water binding capacity, mechanical property, biodegradability, and histocompatibility. Whereas BC itself exhibits no antimicrobial activity. To gain antimicrobial activity, several kinds of antibacterial agents have been introduced into BC. However, all of the antibacterial composite dressings are still in the stage of experimental research. In this paper, the types, antibacterial mechanism, and shortcomings of antibacterial composite dressings based on BC are summarized, in order to make prospects of the research trends of antibacterial composite dressings based on BC in future...

Acute respiratory distress syndrome (ARDS) is a life-threatening disease, as acute inflammation in the lungs typically leads to hypoxia and symptoms of dyspnea. The treatment modalities of ARDS include mechanical ventilation, corticosteroid, extracorporeal membranous oxygenation, inhaled nitrogen oxide, and the prone position. Among these, the prone position is supported by evidence showing significantly reduced mortality in patients that adopt this modality. Lying in the prone position reduces atelectatic lung volumes by recruitment of dependent parts and facilitates normal regulation of alveolar ventilation, giving better-matched ventilation perfusion and, thus, improved oxygenation...

Recently, biomimetic wound dressings were introduced as potential replacements for treating skin injuries. Although there are some clinically available skin replacements, the range of wound types and locations necessitates a broader range of options for the clinic. Natural polymeric-based dressings are of central interest in this area due to their outstanding biocompatibility, biodegradability, low toxicity, and non-allergenic nature. Among them, silk fibroin (SF) has exceptional characteristics as a wound dressing...
