The purpose of this study is to assess the impact of 3-days reduced physical activity (\<1500 steps/day) with/without 'exercise snacks' (15 chair stands with calf raises every 30 min) on skeletal muscle metabolic health. Read Less

Simple bone cysts (SBCs) are cysts filled with fluid that occur most frequently in the long bones (arms or legs) of children. There are many ways to treat SBCs but it is unclear if one is better than another. The purpose of this research trial is to compare the effectiveness of two common treatments that are used by surgeons today. Read Less

Physical exercises and transcranial direct current stimulation (tDCS) are both known to reduce chronic pain in structured laboratory studies. The aim of this study is to assess the efficacy of this combined treatment in clinical settings. Read Less

Chronic pain is one of the main factors influencing workers' retention at work. Considering that the prevalence of suffering from chronic pain increases with age, older workers are most likely to be absent from work because of their pain. Transcranial direct current stimulation (tDCS) is a treatment option to reduce chronic pain. This study aims to document the effect of tDCS on pain and work retention in older workers and to compare the traditional tDCS protocol (5 sessions) with an enhanced protocol (11 sessions).

In order to offer a new product improving the healing and/or rehabilitation of injuries or injuries to the wrist and hand, Médicus is seeking to develop a new orthosis for the wrist and hand by 3D printing. This project will focus on the development of an orthosis related to carpal tunnel syndrome as well as droopy hand. Among the issues to be addressed in this development proposal, the investigators find: 1) Identification of the best methodology for taking digital impressions; design of an orthosis with the following characteristics: (i) no external attachment system, (ii) spiral design with a thumb ring, (iii) manufacturing by 3D printing and (iv) a cost of less than $150 ;3) Performing technical and clinical trials.

The main goal of this study is to compare traditional cataract surgery with two new technologies: the femtosecond laser and the new Active Sentry handpiece. The femtosecond laser is used in several fields of ophthalmology and allows to automate multiple key steps of cataract surgery. The new generation of handpiece called Active Sentry has the particularity to detect the pressure inside the eye in real time and to adjust it to avoid large variations. Theses technologies would potentially increase the efficacy and safety of standard cataract surgery. This study therefore aims at evaluating the differences in cumulative dissipated energy and endothelial cell loss between femtosecond laser assisted cataract surgery with the new Active Sentry handpiece compared to standard phaco with new (Active Sentry) or older handpieces (OZil).

Body Dysmorphic Disorder (BDD) affects 2.3% of the population and is characterized by excessive concerns with imagined or minor defects in physical appearance. Retrospective outcome studies suggest patients affected by BDD don't typically benefit from surgical treatments while cognitive behaviour therapy (CBT) appears to provide symptom - reducing and distress - reducing benefits. Two different 8-week online CBT approaches to assisting individuals with this disorder are compared: one approach will integrate mindfulness meditation methods (in combination with CBT) and one approach will employ CBT methods without reference to mindfulness meditation.

Anxiety feeds the avoidance of dental treatments, leading to the neglect of general oral health. This avoidance is often amplified by the fear of potential pain and dissatisfaction after a dental appointment. A music listening intervention could be beneficial to reduce anxiety, pain and dissatisfaction. This intervention has the advantage to be non-invasive, cheap, and easy to implement in clinical settings. The objective of this study is to explore the effects of a personalised musical intervention on anxiety, pain and dissatisfaction associated with an autogenous gingival graft in comparison to the use of an audiobook (control). In this regard, three groups of patients will receive the gingival graft along with the personalized music intervention (n=20), an audiobook (n=20) or standard care (n=20). Participants will be distributed randomly between conditions in a single blind design (surgeons will be unaware of the condition). However, since the third standard care control group was added as of 07-01-2023, all recruited participants will be enrolled in the standard care control group (non-randomized). Self-reported measures of anxiety, pain, and dissatisfaction will be taken at different times (baseline, preoperative, postoperative, and follow-up). Read Less

This multicenter study will enroll 100 patients with acute traumatic cervical and thoracic SCI who have a lumbar intrathecal catheter inserted within 24 hours of their injury. The lumbar intrathecal catheter will be inserted pre-operatively for the measurement of ITP and the collection of cerebrospinal fluid (CSF) samples. SCPP will be calculated as the difference between MAP and the ITP. There are two important distinct yet related objectives in this prospective interventional study. 1. Determine the effect of SCPP maintenance ≥ 65 mmHg in acute SCI on neurologic recovery as measured by ASIA Impairment Scale (AIS) grade conversion and motor score improvement. 2. Collect CSF and blood samples for the measurement of neurochemical biomarkers and storage for future biomarker discovery and validation studies. Read Less

The uncertainty regarding the management of Unruptured Intracranial Aneurysms (UIAs) has not progressed in the last 30 years. The fundamental ethical basis for this study is that physicians should only offer a risky preventive treatment when it has been shown to be beneficial. Before that, such treatment should be offered as an RCT. The CAM trial offers a comprehensive framework, so that all patients confronted with the clinical dilemma can be offered participation. The prinicpal questions to be addressed are : 1. do patients with UIAs, considered for curative treatments, have a better long-term clinical outcome with active treatment or conservative management? 2. when patients are considered ineligible for conservative management, and surgical and endovascular management are both judged reasonable, do patients with UIAs have a better long-term clinical outcome with surgical or endovascular management? The primary hypothesis for patients allocated to at least 2 options, one of which is conservative management is: the 10 year combined neurological morbidity and mortality (mRS\>2) will be reduced from 24% to 16% (beta 80%; alpha 0.048; sample size 961 patients (836 plus 15% losses to FU and cross-overs) with active treatment. This study is designed as a pragmatic, comprehensive way to address the unruptured aneurysm clinical dilemma, combining large simple RCTs whenever patients are judged eligible for more than one management option, or otherwise a registry of each option. All patients with one or more UIAs will be eligible for participation in either a registry or one of the trials. Patients will be followed for 10 years according to a standard of car follow-up schedule. The primary outcome is survival without neurological dependency (mRS\<3) at 10 years. The secondary outcomes are: 1. the incidence of SAH during follow-up and related morbidity and mortality; 2. the morbidity and mortality related to endovascular or surgical treatment of the UIA at one year; 3. overall mortality at 1, 5 and 10 years; 4. overall morbidity (mRS\>2) at 1, 5 and 10 years; 5. length of hospitalization; 6. discharge to location other than home Read Less

The study is designed to determine whether hemorrhage within the injured spinal cord is influenced by mean arterial pressure (MAP) augmentation with vasopressors and by venous thromboembolism (VTE) prophylaxis with anticoagulants in the first two weeks following a traumatic spinal cord injury (tSCI).

The study involves the 'first-in-human' evaluation of a novel optical sensor which uses near-infrared spectroscopy (NIRS) technology to assess oxygenation and hemodynamics of the injured spinal cord. The NIRS sensor is laid on top of the dura, at the site of the SCI, and emits near-infrared light signals into the cord to measure tissue oxygenation and tissue hemodynamics in real-time. Our testing of this novel NIRS sensor in patients with acute SCI represents the first step in translating this technology for human use. Read Less
