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).

Around the time of birth, some babies experience a condition called asphyxia, which means that their brain and other organs do not receive enough blood and/or oxygen to work properly. This life-threatening condition accounts for nearly 1 out of 4 deaths of all babies around the world, and often leads to severe brain damage, cerebral palsy, epilepsy, and trouble with learning and functioning in everyday life. At this time, no treatment is available to repair the brain damage caused by asphyxia. Excitingly, a drug called sildenafil (Viagra®) is already given safely to babies who suffer from increased blood pressure in their lungs' vessels. Recent studies using a laboratory model of asphyxia at birth suggest that sildenafil may also repair the brain damage caused by asphyxia. Similarly, recent small studies have shown that it is both feasible and safe to give sildenafil to human babies, who suffered from asphyxia at birth. These studies also highlight the first promising signs that sildenafil may improve how the brains of these babies work, which is consistent with the abovementioned laboratory studies. On the basis of these previous researches, the investigators predict that sildenafil can repair the damage to a baby's brain. The investigators will test whether sildenafil can be safely given to a large group of human babies who suffer from asphyxia at birth, and will confirm whether sildenafil improves or not how their brains and hearts/lungs work. This project will enable to determine whether sildenafil is a promising treatment for repairing brain damage in babies who suffer from asphyxia at birth. This project may also provide new solutions for these babies to improve their future life.

Many patients, doctors and others worry that tired doctors provide worse patient care, may not learn well and become burnt-out. In response to these concerns, some countries changed their laws to limit work-hours for doctors in training ('residents'). In Canada, most residents work six or seven 24-30h shifts each month. A recent Canadian report ordered by Health Canada said that making good decisions about resident work-hour rules was "significantly limited by quality evidence, especially evidence directly attributable to the Canadian context." Creating this evidence is the main goal of this research. The pilot study in 2 intensive care units(ICU) found that shorter shifts may be worse for patients, and for residents were more tiring than expected but improved wellbeing. Learning was not assessed. Previous studies on resident work-hours report similar findings: conflicting effects for patients, benefits for resident wellbeing, inconsistent and under-studied effects on learning. Overall, these results are not conclusive and confirm the need for a larger study. The current study will provide high-quality Canadian evidence. The investigators will compare two common ICU schedules used in Canada: resident shifts of 16h and 24h. ICU patients are very sick, there is little margin for error: they need doctors who know them well and are thinking clearly. The effects of each schedule on patients and residents will be measured. For patients, mortality rates and harm caused by care in ICU will be studied. For resident education, their learning about managing common illnesses in ICU, to do basic ICU procedures, and communicate with families will be studied. For resident wellbeing measures will include sleepiness, other fatigue symptoms, and burnout. Investigators will study both resident and patient outcomes so that Canadians can understand trade-offs linked to changing schedules. With this knowledge, Canadians can expect safer care for today's patients and better-trained doctors for the patients of tomorrow.

EMMA-Can is a prospective cohort study to assess the safety and effectiveness of MMA-embolization for the treatment of CSDH. Hypothesis- EMMA reduces the recurrence rate of SDH with or without concomitant surgical evacuation.

Moderate-severe intraventricular hemorrhage (msIVH, Grades II-IV) is a significant neurological complication among extremely low gestational age neonates (ELGANs, \<=27+6 weeks) and is associated with long-term neuro-disabilities. In Canada, msIVH affects \~25-30% of the 1300 ELGANs born annually, with little change in incidence over last decade. Typically, it occurs between days 2-7 of age, providing a finite window of opportunity. Instituting therapies at the population level, however, exposes many low-risk infants to side effects, adversely affecting risk-benefit profile and requiring large sample sizes in trials. A targeted preventative approach, though ideal, is currently challenged by our inability to reliably identify at-risk ELGANs early after birth. Near-infrared spectroscopy (NIRS) has emerged as a promising non-invasive bedside neuromonitoring tool. Pilot studies using NIRS, including ours, found lower cerebral saturations (CrSO2) and greater periods of altered cerebral autoregulation in infants who later developed msIVH. However, a systematic planned investigation is needed to establish the predictive characteristics of NIRS-derived markers, using clinically translatable methods (cumulative burden over time-period vs. single time-point values) and identify their relative performance at different time-points during transition. Further, incorporating echocardiographic (ECHO) hemodynamic markers, known to be associated with msIVH, may allow for the establishment of robust multi-model prediction models and the gain of mechanistic hemodynamic insights to inform future management. Hence, our objective is to investigate the utility of multi-modal assessment using NIRS and ECHO for early identification of ELGANs at risk of msIVH, and generate clinically applicable predictive model(s).

Timely access to family-centred services for children with disability and their families is important to support their development and well-being. Currently, many children face long wait times and barriers to services. Lack of access can lead to negative impacts for children and stress for their families. With the COVID-19 pandemic, these issues have been made more challenging with the loss of rehabilitation support for children, increasing stress on families. During this time, therapists moved to telehealth service delivery to support children and families. We know that telehealth can improve access to services, children's outcomes, and family satisfaction, and that telehealth a key element of Family Centred Services (FCS) in pediatric rehabilitation. FCC include practices that promote flexibility, respect and dignity for families' views, knowledge and strengths, effective information sharing, partnership and collaboration in decision making, and coordinated and comprehensive care. FCC focuses on developing collaborative family-provider relationships, where parents are active participants in collaborative goal-setting, therapy planning, implementation, and evaluation, and where activities are integrated within daily routines and contexts (e.g., home and community). Compared to traditional service delivery methods, telehealth offers opportunities to enhance FCC practices. FCC provides alternate, convenient, and flexible ways to partner with families, respecting their characteristics and barriers, allows knowledge and information sharing about the child within their contexts, supports family decision making and parents' well-being, and has been recognized as an important addition to comprehensive care coordination and service delivery. Telehealth is an important and effective alternative for families living in both urban and remote or underserved areas and can be more convenient than in-person visits (e.g., less travel time, schedule flexibility). However, the use of telehealth prior to the pandemic was low in pediatric rehabilitation. In addition, many therapists report delivering telehealth without prior experience, and lack confidence, knowledge, and training in effective intervention strategies. Although therapists' knowledge, skills and attitudes toward telehealth can improve with time and experience, training and support are required for behavioural changes to occur. Following the pandemic, there has been continued support for the use of FCT and for its ongoing use to support families of children with disability. Pediatric rehabilitation therapists, service managers, professional associations, policy makers, and families are all making the case for not "returning to normal", and are asking for help to keep telehealth as part of FCS care. The goal of the current study is to evaluate the use and effectiveness of a Training Intervention and Program of Support (TIPS) to increase the uptake of FCT in pediatric rehabilitation centres across Canada. The main research question is: Can TIPS be adapted to increase the use of FCT interventions by therapists working in different contexts? The primary objectives are to: 1. Evaluate the use of FCT regarding: 1. Therapists' desire to use vs actual use of FCT practices 2. Use of FCT practices as they were intended to be used Secondary objectives are to: 2. Describe the variations required to adapt the TIPS to meet each site's needs 3. Identify factors that influence FCT use and adherence 4. Evaluate the effectiveness with regards to: 1. Service wait-times 2. Family-centredness of services 3. Changes in service delivery 5. Evaluate the costs (and possible cost savings) related to increased use of FCT The primary hypotheses are that therapists' desire to adopt FCT and deliver FCT practices as intended will (i) improve slightly in the short term (i.e., one-month post-TIPS), yet (ii) will improve significantly post-TIPS, (iii) while actual use will vary over time, across sites and therapists, and will depend on therapist-, client-, organizational- and system-factors. For the secondary hypotheses, the investigators expect that, for sites with the largest changes in desire to use and use of FCT practices as intended, (iv) wait times will significantly decrease and (v) families' perceptions of service quality will significantly improve post-TIPS.

MyCardiacRecovery (MyCaRe) is an interactive platform that includes a standardized educational format and interactive tracking (wound healing and activity progression using photo capabilities and Fitbit Inspire 2 accelerometer) support during the first 6 to 8 weeks post hospital discharge. This android application will help patients and family navigate their way through the continuum of care by providing an: a) integrated link between acute care and outpatient cardiac rehab (CR) for efficient coordination of information and reduction in duplication of services; b) patient care and education materials designed to address salient recovery questions; c) improved communication between the patient and care providers and, d) ensure streamlined systematic referral to CR. This innovative strategy has the potential to positively impact patient satisfaction, improve patient outcomes and possibly minimize financial constraints placed on the health care system. Phase 1 (preliminary usability testing) of prototype 1.0 is complete. Phase 2 will focus on testing MyCaRe 2.0 in a sample of post cardiac surgery patients using a pilot randomized controlled trial (RCT) design.

The WBDR is an international observational disease registry of patients with hemophilia. It will provide a platform for a network of hemophilia treatment centres (HTCs) around the world to collect uniform and standardized patient data and guide clinical practice. With informed consent from the patient, the WBDR stores anonymous data about the person's disease, such as hemophilia type and severity, symptoms, and treatment.

Osteoporosis is a bone disease that can result in fractures, disability and an increased risk of premature death. Exercise is recommended for fall and fracture prevention, but health care professionals often recommend walking or lower intensity community exercise classes, which may not be effective for building bone. Further, individuals with osteoporosis are often told to avoid lifting or moving in certain ways, which creates fear and activity avoidance. Conversely, research suggests that to stimulate bone, you need higher loads on bone, with either higher intensity resistance training or impact exercise - the types of things people with low bone mass are told to avoid. Our study will examine different types of exercise intensity and how they translate to building bone in people with low bone mineral density (BMD).

The purpose of this study is to compare the effects on patients with metastatic melanoma of taking a government approved and paid-for PD-1 inhibitor intermittently, with taking the same type of agent continuously. Researchers want to see if the two ways of giving this type of treatment work equally well in extending the life of patients with melanoma, or not.
