Platelet-Rich Plasma (PRP) is an autologous biological therapy obtained by centrifuging the patient's own blood to concentrate platelets. The addition of autologous thrombin and calcium chloride to PRP allows the production of a semi-solid form called PRP gel. PRP gel is increasingly used in a variety of tissue defects and predominantly in the management of non-healing chronic wounds. The topical application of PRP gel seems promising due to the capability of platelets to store and secrete growth factors (GF), fibrin and cytokines, which are essentials for wound healing...

Hepatic fibrosis is caused by exaggerated wound healing response to chronic injury, which eventually leads to hepatic cirrhosis. Differentiation of hepatic stellate cells (HSCs) to myofibroblast-like cells by inflammatory cytokines is the critical step in fibrosis. This step is accompanied by enlargement of the endoplasmic reticulum (ER) and Golgi apparatus, suggesting that protein synthesis and secretion are augmented in the activated HSCs. However, the process of rearrangement of secretory organelles and their functions remain to be fully elucidated...

Radiation therapy (RT) is an essential component for management of many cancers. Veterinary health care professionals must counsel owners about the potential side effects of RT, the anticipated management plan, and associated costs. For most veterinary patients treated with RT, acute radiation side effects are mild; however, careful radiation treatment planning and appropriate management of acute side effects are essential to try to prevent chronic sequelae and the need for ongoing wound care. This article reviews acute and late side effects to the skin and their management...

Chronic wounds, in particular venous leg ulcers (VLU), represent a substantial burden for economies, healthcare systems and societies worldwide. This burden is exacerbated by the recalcitrant nature of these wounds, despite best practice, evidence-based care, which substantially reduces the quality of life of patients. Furthermore, co-morbidities such as diabetes and cardiovascular disease within ageing populations further contribute to the increasing prevalence in developed countries. This review provides an overview of the literature concerning the cellular and molecular mechanisms of wound healing and aspects where this process fails, resulting in a chronic wound...

Cutaneous wound healing is a complex mechanism with multiple processes orchestrating harmoniously for structural and functional restoration of the damaged tissue. Chronic non-healing wounds plagued with infection create a major healthcare burden and is one of the most frustrating clinical problems. Chronic wounds are manifested by prolonged inflammation, defective re-epithelialization and haphazard remodeling. Matrix metalloproteinases (MMPs) are zinc dependent enzymes that play cardinal functions in wound healing...

OBJECTIVE: The use of cold atmospheric pressure plasma (CAPP) as a new therapeutic option to aid the healing of chronic wounds appears promising. Currently, uncertainty exists regarding their classification as medical device or medical drug. Because the classification of CAPP has medical, legal, and economic consequences as well as implications for the level of preclinical and clinical testing, the correct classification is not an academic exercise, but an ethical need. METHOD: A multidisciplinary team of physicians, surgeons, pharmacists, physicists and lawyers has analysed the physical and technical characteristics as well as legal conditions of the biological action of CAPP...

OBJECTIVE: Postoperative delayed wound healing, surgical site infections (SSIs), and other wound complications are associated with increased morbidity and health-care costs. In cardiothoracic surgery, wound complications can have life-threatening consequences. In recent years, negative pressure wound therapy (NPWT) has been applied over closed surgical incisions to help reduce tension and protect from external contamination. We report our initial experiences using a closed incision negative pressure therapy (ciNPT) over clean, closed sternotomy incisions at an Irish tertiary referral centre...

OBJECTIVE: Bacteria in chronic wounds are invisible to the naked eye and can lead to delayed wound healing. Point-of-care bacterial fluorescence imaging illuminates a wound with 405nm light, triggering bacteria to produce red fluorescence and enabling real-time bacterial localisation. Prospective, single-blind clinical trials (clinicaltrials.gov #NCT02682069, #NCT03091361) were conducted to determine the positive predictive value (PPV) of this red fluorescence for detecting bacteria in chronic wounds...

Vacuum-assisted closure(VAC) therapy is mainly used for tissue defects. VAC therapy can remove exudate that could impair the healing process. We applied VAC therapy in patients considered at high risk of surgical site infection who underwent cardiovascular surgery via standard median sternotomy. Risk factors included advanced heart failure, obesity, diabetes mellitus, steroid administration, immunosuppressant administration, and chronic renal failure, etc. VAC therapy was used in 134 patients. Only 3 of these patients (2...

Hyperbaric oxygen (HBO₂) therapy is currently used for the treatment of chronic wounds, radiation-induced soft tissue necrosis, several oxygen-deficiency conditions and decompression sickness. In addition to the current indications, much empirical and experimental data suggest that HBO₂ therapy may benefit autoimmune diseases by suppressing immunity, but the underlying mechanism is not well understood. Therefore, in the present study, we investigated whether HBO₂ prevents the development of collagen-induced arthritis (CIA) in association with alteration of the immune balance between pro-inflammatory Th17 and anti-inflammatory regulatory T cells (Tregs)...

The aim of this study was to investigate how people self-treat chronic wounds, why they self-treat and the assistance and support that they receive. The increasing emphasis on self-management of chronic conditions, the potential benefits of self-treatment to the health care consumer and competing demands on health care funding are good reasons to investigate self-treatment of chronic wounds as we have little data on this group of individuals. A survey study was conducted in Australia. A non-random sample of 100 participants was recruited...

Adverse immune reactions prevent clinical translation of numerous implantable devices and materials. Although inflammation is an essential part of tissue regeneration, chronic inflammation ultimately leads to implant failure. In particular, macrophage polarity steers the microenvironment toward inflammation or wound healing via the induction of M1 and M2 macrophages, respectively. Here, this paper demonstrates that macrophage polarity within biomaterials can be controlled through integrin-mediated interactions between human monocytic THP-1 cells and collagen-derived matrix...
