Fluid expansion with isotonic crystalloids is a first-line intervention in the treatment of patients with acute kidney injury (AKI). While it is generally accepted that the timely correction of kidney hypoperfusion will minimize the extent of injury as well as potentially facilitate recovery, there are potential harms involved in indiscriminate administration of intravenous fluids. Although anticipating fluid tolerance is part of the clinical evaluation of a patient for whom intravenous fluid therapy is considered, it has been suggested that using Point-Of-Care ultrasound (POCUS) may enable the early identification of patients with a high-risk of congestive complications and guide clinical decisions with greater precision\[1\]. However, it has not been shown that providing this information in the context of AKI result in a change in management or a prevention of complications. This single-center pilot randomized controlled trial aim to determine the feasibility of comparing a management including a POCUS evaluation of fluid tolerance to usual care in non-critically ill patients with AKI. In the intervention group, a POCUS evaluation will be performed and interpreted by experienced staff producing a report that will be presented to the attending care team. This assessment will be repeated 48-72 hours later. The primary aim of the study will be to establish the feasibility of this intervention. Secondary objectives will include determining the difference between the intervention arm and the control arm in relationship with fluid administration, diuretic use, evolution of kidney function, and intensification of care.

The use of a splint, serial casting and passive stretching have been described in the literature as conservative interventions to manage joint contractures after burn injury. There is a paucity of literature investigating the effect of serial casting on scar contractures following upper extremity (UE) burn injury in adults and a lack of studies using strong methodological approaches. There are also no studies investigating the effect of casting on hypertrophic scars (HSc) and on self-reported UE function. This study is a longitudinal case series design with a criteria for change on the use of serial casting for the treatment of upper extremity burn contractures. The purpose of this study is to estimate the extent to which range of motion (AROM and PROM), scar characteristics and patient-reported upper-extremity function changes following an individually-tailored serial casting treatment program after switching from one week of usual care and to determine if these changes can be maintained 3 weeks after stopping serial casting, for adult burn survivors who developed an upper-extremity joint contracture greater than 15% normal range of motion within 1-year post-burn. This study will be a longitudinal case series design with a criteria for change. A minimum of 12 participants will be recruited from the "Centre d'expertise pour les victimes de brûlures graves de l'ouest du Québec" (CEVBGOQ) and will undergo one week of "usual care". If the PROM of the joint does not improve after one week of usual care, the participant will start the serial casting process, which will be prescribed by the treating OT. PROM/AROM and scar characteristics will be measured using a revised goniometry protocol that incorporates cutaneokinematics (CKM) principles and precise skin measures (DermaScan C, Cutometer®, Mexameter® and Tewameter®) at baseline, every Monday and Friday of the treatment weeks and 3 weeks after treatment cessation. Self-reported UE function and satisfaction related to scarring will be assessed at baseline and 3 weeks after treatment cessation using the QuickDASH and the patient satisfaction assessment scale (PSAS). Analysis on ROM and scar characteristic will be conducted using a graphical representation with a projected "usual care" regression line to count how many outcomes were over the line once the treatment was introduced. This study will contribute to building evidence for the use of serial casting following UE burn contractures in the adult population. Read Less

This is a randomized parallel group clinical trial which will be conducted in three countries (Spain, Canada and Belgium) comparing Botulinum Toxin type A (BTX-A) and Dry Needling (DN) effectiveness for post-stroke spasticity in participants who had a first stroke in the previous 12 months and have plantar flexor spasticity. Participants will be randomly allocated to receive either one session of BTX-A or 12 weekly sessions of DN. Blinded evaluators will assess the effects before, during, and after treatment, and at a 4-week follow-up. Read Less

This study will look at silicone tape compared to the current no dressing standard at the investigators institution, to determine if silicone tape provides a significant improvement in post-abdominoplasty scar appearance. Silicone tape will be added to half of the abdominoplasty incision of patients undergoing abdominally-based breast reconstruction procedures two weeks after their operation. They will be followed up and assessed at specific timepoints to determine whether the silicone improves scar outcomes in these patients. Read Less

Total Knee Replacement (TKR) is an operation to help with the pain and decreased function that happens with end stage arthritis of the knee. This operation has been shown to be very successful at relieving pain and improving patient mobility; however, some studies have shown that up to 20% of TKR recipients are not happy with their knee replacement. All of the reasons why some patients are not pleased with the outcome of surgery are not known, but one of the possible causes is the way the implants are placed, or aligned, during surgery. Most TKRs are aligned in a fashion that the bones in the leg are completely straight after surgery. This is known as mechanically aligning a TKR. A different alignment method known as kinematic alignment respects the natural bow legged or knock kneed alignment of the patient. It is hoped that kinematically aligning a knee replacement will improve how the knee feels to the patient and therefore improve their satisfaction. Another potential factor affecting the outcomes of TKR is obtaining optimal soft tissue balance. The challenge with balancing a TKR is that traditional operative techniques rely on subjective feel of the knee stability during surgery. The balance or tension in the knee can however be objectively measured using specialized intraoperative pressure sensing devices. The purpose of this study is to assess the impact of kinematically aligned TKR on the pressures measured by Verasense during total knee replacements. The study will also determine if differences in the pressure measured during TKR surgery impact patient outcomes after surgery. Read Less

The purpose of this study is to find out whether a novel manualized intervention, called Emotion and Symptom-focused Engagement (EASE), that combines psychological support with symptom screening plus triggered referral to early palliative care for symptom control, reduces psychological distress and physical symptom burden in individuals newly diagnosed with acute leukemia. To do this, half of the participants in this study will receive the usual care offered to patients with acute leukemia and half of the participants will receive usual care plus the EASE intervention.

The goal of this observational study is to establish a video/image library dataset of complete endoscopy or partial colonoscopy procedures for patients with rectal cancer or inflammatory bowel disease (IBD). With this video/image library, the aims are: * to develop and validate novel AI-empowered solutions to automatically detect and report endoscopy quality metrics * to develop automated endoscopy reporting solutions, auditing, and educational tools for residents and fellows to enhance their endoscopy skills. The hypothesis is that a heterogeneous video/image library will provide: * comprehensive and robust source material to develop AI models * real-time quality feedback at the end of an endoscopy procedure.

This pilot study will evaluate the feasibility and safety of using 1:1 tetrahydrocannabinol (THC):Cannabidiol (CBD) cannabis oil as an adjunct therapy to methadone-based Opioid Agonist Therapy (OAT) for individuals with opioid use disorder (OUD) in a community setting. Read Less

This is a prospective study that is the first to implement resect and discard and diagnose and leave strategies in real-time practice using stringent documentation and adjudication by 2 expert endoscopists as the gold standard. The primary aim of this study is to show the accuracy of intracolonoscopy AI-assisted optical diagnosis (CADx; autonomous or with human input) when the AI-assisted optical diagnosis made by the expert endoscopists is used as the reference standard. The specific aims are: 1. To evaluate the accuracy of intracolonoscopy AI-assisted optical polyp diagnosis (autonomous or with human input) by comparing it to the obtained optical histology diagnoses provided by two independent expert endoscopists as the reference standard. 2. To evaluate the agreement between the intracolonoscopy AI-assisted optical polyp diagnosis (autonomous or with human input) and the AI-assisted optical diagnosis performed by two independent expert endoscopists. 3. To determine whether AI-assisted optical polyp diagnosis for diminutive (1-5 mm) polyps can be implemented in routine clinical practice by demonstrating that at least 70% of the approached patients are interested in undergoing AI-assisted optical diagnosis (autonomous or with human input). 4. To evaluate the cost savings resulting from replacing pathology with AI-assisted optical diagnosis. Read Less
