The concentrations of the redox pair hydrogen peroxide (H2O2) and oxygen (O2) can promote or decelerate the progression and duration of the wound healing process. Although H2O2 can reach critically high concentrations and prohibit healing, a sufficient O2 inflow to the wound is commonly desired. Herein, we describe the fabrication and use of a membrane that can contemptuously decrease H2O2 and increase O2 levels. Therefore, hematite nanozyme particles were integrated into electrospun and cross-linked poly(vinyl alcohol) membranes...

The management of wounds in patients on anticoagulant therapy who require oral surgical procedures is problematic and often results in a non-satisfactory healing process. Here we report a method to prepare an advanced dressing able to avoid uncontrolled bleeding by occluding the post-extractive alveolar wounds, and simultaneously, capable of a fast release of tranexamic acid (TA). Composite alginate/hyaluronan (ALG/HA) sponge dressings loaded with TA were prepared by a straightforward internal gelation method followed by a freeze-drying step...

Negative-pressure wound therapy represents a relatively new strategy for wound management. Significant, life-threatening complications (bleeding, infection, and retained dressing material) have been associated with negative-pressure wound therapy. As a result, the Food and Drug Administration published several warnings to negative-pressure wound therapy users and recommended that clinicians ordering, managing, and/or monitoring negative-pressure wound therapy be aware of the potential complications and be prepared to take prompt action to reduce patients' risk for harm...

The present work investigates Ca(2+) -crosslinked nanofibrillated cellulose hydrogels as potential hemostatic wound dressings by studying core interactions between the materials and a central component of wounds and wound healing-the blood. Hydrogels of wood-derived anionic nanofibrillated cellulose (NFC) and NFC hydrogels that incorporate kaolin or collagen are studied in an in vitro whole blood model and with platelet-free plasma assays. The evaluation of thrombin and factor XIIa formation, platelet reduction, and the release of activated complement system proteins, shows that the NFC hydrogel efficiently triggered blood coagulation, with a rapid onset of clot formation, while displaying basal complement system activation...

Composed in a large extent of water and due to their non-adhesiveness, hydrogels found their way to the wound dressing market as materials that provide a moisture environment for healing while being comfortable to the patient. Hydrogels' exploitation is constantly increasing after evidences of their even broader therapeutic potential due to resemblance to dermal tissue and ability to induce partial skin regeneration. The innovation in advanced wound care is further directed to the development of so-called active dressings, where hydrogels are combined with components that enhance the primary purpose of providing a beneficial environment for wound healing...

Skin is the outermost covering of the human body and at the same time the largest organ comprising 15% of body weight and 2 m(2) surface area. Skin plays a key role as a barrier against the outer environment depending on its thickness, color and structure, which differ from one site to another. The four major types of problematic wounds include ulcers (diabetic, venous, pressure) and burn wounds. Developing novel dressings helps us to improve the wound healing process in difficult patients. Recent advances in regenerative medicine and nanotechnology are revolutionizing the field of wound healing...

Jacopo Berengario da Carpi (c.1460-c.1530) made several important advances in anatomy, being universally considered the founder of 'animated anatomy' (anatomia animata). In addition to being a famous anatomist, Berengario was also a highly regarded surgeon. One of his famous clients was Lorenzo de' Medici, Duke of Urbino (1492-1519). In 1517, Lorenzo suffered a skull injury from an harquebus shot and Berengario was asked to come to his bedside. Lorenzo's case gave Berengario the opportunity to write his Tractatus de Fractura Calve sive Cranei, published in Bologna by Gerolamo Benedetti in 1518...

According to the latest report from the World Health Organization, an estimated 265,000 deaths still occur every year as a direct result of burn injuries. A widespread range of these deaths induced by burn wound happens in low- and middle-income countries, where survivors face a lifetime of morbidity. Most of the deaths occur due to infections when a high percentage of the external regions of the body area is affected. Microbial nutrient availability, skin barrier disruption, and vascular supply destruction in burn injuries as well as systemic immunosuppression are important parameters that cause burns to be susceptible to infections...

Chronic non-healing wounds remain a major clinical challenge that would benefit from the development of advanced, regenerative dressings that promote wound closure within a clinically relevant time frame. The use of copper ions has shown promise in wound healing applications possibly by promoting angiogenesis. However, reported treatments that use copper ions require multiple applications of copper salts or oxides to the wound bed, exposing the patient to potentially toxic levels of copper ions and resulting in variable outcomes...

Despite a range of advanced wound dressings that can facilitate wound healing, there are still no clinically used dressings for effective local pain management. The latter was the main motivation of the present study. We designed a novel wound dressing with three layers. A macro-porous polyethylene terephthalate (PET) mesh with incorporated lidocaine, a fast-acting local anesthetic, was chosen as the layer in direct contact with the skin. Fast release from this layer enables an immediate pain relieving effect, caused by dressing changes...

The tissue engineering field has developed in response to the shortcomings related to the replacement of the tissues lost to disease or trauma: donor tissue rejection, chronic inflammation and donor tissue shortages. The driving force behind the tissue engineering is to avoid the mentioned issues by creating the biological substitutes capable of replacing the damaged tissue. This is done by combining the scaffolds, cells and signals in order to create the living, physiological, three-dimensional tissues. A wide variety of skin substitutes are used in the treatment of full-thickness injuries...
