The presence of biofilms in chronic non-healing wounds, has been identified through in vitro model and in vivo animal data. However, human chronic wound studies are under-represented and generally report low sample sizes. For this reason we sought to ascertain the prevalence of biofilms in human chronic wounds by undertaking a systematic review and meta-analysis. Our initial search identified 554 studies from the literature databases (Cochrane Library, Embase, Medline). After removal of duplicates, and those not meeting the requirements of inclusion, nine studies involving 185 chronic wounds met the inclusion criteria. Prevalence of biofilms in chronic wounds was 78.2 % (confidence interval [CI 61.6-89, p<0.002]). The results of our meta-analysis support our clinical assumptions that biofilms are ubiquitous in human chronic non-healing wounds.

The skeletal system, composed of bones, muscles, joints, ligaments, and tendons, serves as the foundation for maintaining human posture, mobility, and overall biomechanical functionality. However, with ageing, chronic overuse, and acute injuries, conditions such as osteoarthritis, intervertebral disc degeneration, muscle atrophy, and ligament or tendon tears have become increasingly prevalent and pose serious clinical challenges. These disorders not only result in pain, functional loss, and a marked reduction in patients' quality of life but also impose substantial social and economic burdens.

The increased cost and morbidity associated with diabetic foot ulcers (DFUs) place a substantial strain on the entire global healthcare system. In this trial, 24 subjects with a chronic DFU, Wagner grade 1 (University of Texas grade 1A), were treated with Standard of Care (SOC) therapy and randomized, one-half to receive advanced high-purity Type-I collagen-based skin substitute (HPTC; manufactured by Encoll Corp., Fremont, CA, USA), and the other half to receive a dehydrated human amnion/chorion membrane (dHACM) or viable cryopreserved human placental membrane (vCHPM).

Skin serves as the first-order protective barrier against the environment and any significant disruptions in skin integrity must be promptly restored. Despite significant advances in therapeutic strategies, effective management of large chronic skin wounds remains a clinical challenge. Dermal fibroblasts are the primary cell type responsible for remodeling the extracellular matrix (ECM) in wound healing.

Background: The pathogenesis of deterministic radiation damage is not clearly understood, but it has been reported that fibroinflammatory pathways are up-regulated. We hypothesized that the number of adipose-derived stem/stromal cells (ASCs) decline after radiotherapies, preventing normalization of fibrosis and angiogenesis, resulting in chronic radiation damages that progress over time.

Background: Identification of peripheral nerve injuries of the head and neck can be challenging due to a broad spectrum of symptoms from neuropathic pain to headaches and migraine. This article aimed to present the clinical features and diagnostic workup of patients with acute and chronic peripheral nerve injuries of the head and neck using magnetic resonance neurography (MRN), to demonstrate potential advantages compared with conventional magnetic resonance imaging (MRI).
Methods: Patients who presented with suspected peripheral nerve injury were either referred for a conventional MRI or MRN.
