Patients who undergo total ankle replacement surgery can sometimes develop problems with wound healing after their operation. These complications may include delayed healing, wound opening, or infection, which can lead to additional clinic visits, further surgery, and longer recovery times. Tranexamic acid (TXA) is a medication that has been used safely for many years in many types of surgery to reduce bleeding. Some studies suggest that it may also improve wound healing after foot and ankle surgery by reducing bleeding and swelling around the surgical site. However, there is not enough high-quality evidence to know whether TXA truly improves outcomes for patients undergoing total ankle replacement. This study is a pilot clinical trial designed to determine whether a larger study can be successfully carried out. Approximately 40 patients undergoing total ankle replacement surgery at The Ottawa Hospital will be randomly assigned to receive either TXA or a placebo (salt water solution). Neither the patients nor their health care team will know which treatment was given until the study is complete. All patients will receive standard surgical care and follow-up regardless of which group they are assigned to. Researchers will then collect information about wound healing, complications, additional surgeries, and infections at routine follow-up visits for up to six months after surgery. The outcomes will be compared between patients in each group. The results of this pilot study will help determine whether a larger clinical trial is feasible and may provide early information about whether TXA could improve recovery after total ankle replacement surgery. Ultimately, this research aims to improve patient outcomes and reduce complications following ankle replacement surgery.

Burn wound infections remain a major source of morbidity in patients with thermal injuries and contribute to delayed healing, graft loss, and prolonged hospitalization. The emergence of antimicrobial-resistant organisms further complicates management and highlights the need for non-antibiotic antimicrobial strategies. Photodynamic therapy (PDT) is an antimicrobial approach that combines a photosensitizing agent with visible light to generate reactive oxygen species capable of killing bacteria. This randomized clinical trial will evaluate the safety and preliminary efficacy of methylene blue-mediated photodynamic therapy for the treatment of burn wound bacterial contamination. Participants receiving standard burn care will be randomized to receive either methylene blue-photodynamic therapy with blue light illumination or light therapy alone during routine dressing changes. Treatments will occur during two consecutive dressing changes. The primary objective is to determine whether methylene blue photodynamic therapy reduces bacterial burden in burn wounds compared with light therapy alone. Secondary outcomes include safety, tolerability, and effects on wound healing.

The investigators want to explore the use of a smartphone app that allows patients to take photos of their wounds in early stages of healing, so that clinicians can monitor wound-healing remotely with the assistance of an AI program. Participants will choose whether they want to be in the control group or the app group. Participants in the app group will be asked to download an app on their personal smartphone before their surgery. After the procedure, participants will upload a photo of their surgery site as well as answer some questions about its characteristics either on a daily or weekly basis. A healthcare provider and the app's AI algorithm will observe this information to determine the risk of infection. Participants in the control group will not be asked to use the app. Their medical record will be monitored by study staff intermittently to see if they develop infection. This study will take approximately 16 weeks.

Enhancing Wound Perfusion in High-Risk Lower Extremity Orthopaedic Surgery: A Feasibility Study on Nitropaste Using Intraoperative SPY Imaging.

This is a multi-center, pragmatic, parallel arm randomized controlled trial (RCT) of 352 patients with high-risk open or closed tibial plateau fracture, high-risk open or closed tibial pilon fracture, or open tibial shaft fracture with incision \>3cm. Eligible participants will be randomized to receive either incisional negative pressure wound therapy (NPWT) or a non-suction standard-of-care wound dressing for their definitive wound management. The primary outcome will be a composite outcome to evaluate clinical status 3 months after randomization.

The purpose of this study is to compare two complex, multi-component evidence-based postpartum interventions in underserved populations of lower socioeconomic status in an effort to reduce maternal morbidity and mortality.

This is a Phase II, randomized, double-blind, placebo-controlled, multi-center study to evaluate the clinical efficacy and safety of Antimicrobial Peptide PL-5 Topical Spray in patients with mild infections of diabetic foot ulcers. Eligible subjects will be randomized (1:1:1) to receive twice a day, 14 days treatment of Antimicrobial Peptide PL-5 Topical Spray (1‰), Antimicrobial Peptide PL-5 Topical Spray (2‰) and topical placebo (vehicle) spray. In this study, the cut-off date for final analysis is defined as the time when all subjects have completed the last visit or discontinued the study

This is a Phase III clinical randomized control trial to investigate differences between patient with an infected nonunion treated by PO vs. IV antibiotics. The study population will be 250 patients, 18 years or older, being treated for infected nonunion after internal fixation of a fracture with a segmental defect less than one centimeter. Patients will be randomly assigned to either the treatment (group 1) PO antibiotics for 6 weeks or the control group (group 2) IV antibiotics for 6 weeks. The primary hypothesis is that the effectiveness of oral antibiotic therapy is equivalent to traditional intravenous antibiotic therapy for the treatment of infected nonunion after fracture internal fixation, when such therapy is combined with appropriate surgical management. Clinical effectiveness will be measured as the primary outcome as the number of secondary re-admissions related to injury and secondary outcomes of treatment failure (re-infection, nonunion, antibiotic complications) within the first one year of follow-up, as defined by specified criteria and determined by a blinded data assessment panel. In addition, treatment compliance, the cost of treatment, the number of surgeries required, the type and incidence of complications, and the duration of hospitalization will be measured.
