Bone is a common site of metastasis for a range of malignancies. Bone metastases have the potential to cause significant morbidity including pain, impairment of ambulation and reduced functional independence. Previous research has shown that pathological fractures are observed in 9 to 29 percent of patients with long bone metastases, and a high proportion of these require surgical intervention to relieve pain and restore function. The goal of this study is to describe the clinical outcomes of patients with femoral metastases at high risk of pathological fracture. Patients referred for treatment of femoral metastases at high risk of fracture will be followed prospectively after undergoing with surgery (± post-operative radiotherapy), or radiotherapy alone. Patient and disease characteristics, ambulatory status and limb function will be documented before treatment. These Clinical outcomes of participants in each treatment group will be measured 6 weeks after treatment, and 3- and 6 months after enrolment, with particular reference to patient-reported outcomes relating to pain, ambulatory status, limb function and quality of life.

Amblyopia is a developmental anomaly resulting from abnormal visual experiences in early life. Amblyopia causes reduced visual acuity in the absence of a pathology. Adult sensory systems are believed to be structurally invariant beyond early, critical periods of development. However, recent evidence suggest that visual functions in adults with amblyopia can be improved with optical correction alone. This study aims to investigate whether improvements in best corrected visual acuity and other visual functions can result following appropriate optical correction in adults with amblyopia. Functional measures relating to vision, binocular vision, and eye movements will be used to assess the efficacy of refractive correction for improving vision. This study will help us better understand the improvements in visual functions following optical correction, as well as the mechanisms underlying neuroplasticity in adults with amblyopia. Read Less

Subjects male and female aged 50-85 with a clinical diagnosis of chronic obstructive pulmonary disease (COPD) or Bronchiectasis, or those with ≥ 10 pack/years smoking history will be imaged with CT and MRI for the development of tools to quantify and validate longitudinal in vivo magnetic resonance imaging phenotypes of COPD and Bronchiectasis.

Healthy volunteers aged 18-85 will undergo hyperpolarized 129-Xe MRI and pulmonary function testing for the development of tools to assess image signal to noise and reproducibility of spin-density and diffusion-weighted imaging. Read Less

Subjects aged 18-85 with lung disease will undergo hyperpolarized Xenon 129 (129-Xe) MRI and Pulmonary Function testing for the development of tools to evaluate the Apparent Diffusion Coefficient (ADC), ventilation defect percent (VDP) and pulmonary gas exchange measurements obtained by analysis of hyperpolarized 129-Xe MRI.

The purpose of the study is to measure the effects of obturator nerve cryoneurotomy, on clinical measures in adult (ages 19+) and paediatric (ages 12-18) patients with hip adductor spasticity, who will receive this procedure as a part of their treatment based on the spasticity treatment available guidelines. The results will provide us valuable information like how long cryoneurotomy is effective, before regeneration happens Read Less

The purpose of the study is to investigate new therapies to alleviate pain on neuropathic chronic pain. At this time, the main purpose is to complete a feasibility or pilot study with 60 participants suffering from neuropathic chronic pain. Participants will be randomized to (1) Ketamine (Hydrochloride) HCL; (2) psychotherapy (using Cognitive Behavioral Therapy); or (3) a combination of Ketamine HL and psychotherapy. Read Less

The purpose of the study is to measure the outcomes of a standard care, an ultrasound guided mini-invasive percutaneous procedure, performed on recent stroke patients on reduces pain, increases function \& quality of life The primary objective of the project is to reduce shoulder and/or knee pain in patients who have had a stroke so that they can more readily engage in rehabilitation. Secondary objectives are to reduce analgesic medications, increase independence and improve range of motion, to promote non-drug treatment measures in the medical toolkit, and to include an interdisciplinary care team in patient selection for interventions.

Residents living in long-term care (LTC) homes spend up to 75% of their day in sedentary, socially withdrawn situations which increases their risk for depression, dementia, decreased functional status and increased care costs. Physical activity is an accepted intervention to improve the physical health, cognition, and well-being of older adults. Moreover, systematic reviews have found that exergaming (i.e. physical activity gamified with technology) offers physical, cognitive, and social benefits by means of dual-task activities that engage both motor and cognitive abilities. The effect of exergaming for older adults in LTC is less clear, as this population has greater health needs related to physical health conditions, cognitive impairment, and functional dependence. Given the increased global demand for LTC, there is a need to develop and assess innovative exergaming technologies that can support the physical and cognitive health of LTC residents. MouvMat is an exergaming technology intervention with an interactive digital gaming surface designed for older adults (OA) in LTC settings. Participants can play familiar games, like Simon or Bingo, by stepping on or tapping the surface with an assistive pointing device. Games can be played individually or with multiple players. LED lights on the surface provide an adaptive digital display and embedded pressure sensors respond to players' input. The investigators collaboratively designed a preliminary prototype with OA aged 65 and older in a pilot project. The overall objective of this proposal is to conduct a pilot RCT of the Mouvmat to evaluate the feasibility, acceptability and efficacy of the exergaming technology to improve the primary outcome of mobility, and the secondary outcomes of cognitive function and social isolation compared to a usual care control group receiving standard recreational programming by recreational therapists.

The proposed study is a phase II, single arm, open-label trial of MR-guided radiation therapy (RT) with risk stratified RT dose selection in patients with anal cancer. Based on previous data, a risk adaptive treatment approached is proposed in 4 groups: Low risk, standard risk, intermediate risk, and high risk. Human papillomavirus (HPV) DNA will be analyzed to identify novel biomarkers that predict chemoradiotherapy (CRT) response and toxicity. Read Less

The goal of this experimental trial is to learn about the changes in bacterial diversity in individuals with type 2 diabetes who perform endurance and strength training at different intensities. Participants with type 2 diabetes will be randomly assigned to 16 weeks of either moderate-intensity endurance and strength training or high-intensity endurance and strength training. Researchers will compare the moderate-intensity and high-intensity exercise groups for differences in glycemia and bacterial diversity. Read Less

The current first-line treatment for opioid use disorder (OUD) in Canada is buprenorphine/naloxone (bup/nx). The standard induction method of bup/nx requires patients to be abstinent from opioids and thereby experience withdrawal symptoms prior to induction, which can be a major barrier in starting treatment. Rapid micro-induction (also known as micro-dosing, low-dose induction) involves the administration of small, frequent does of bup/nx and removes the need for a period of withdrawal prior to the start of treatment. This study aims to compare the effectiveness and safety of rapid micro-induction versus standard induction of bup/nx in patients with OUD. Read Less
