Urea cycle disorders (UCD) are a group of rare inherited metabolism disorders. Infants and children with UCD commonly experience episodes of vomiting, lethargy, and coma. The purpose of this study is to perform a long-term analysis of a large group of individuals with various UCDs. The study will focus on the natural history, disease progression, treatment, and outcome of individuals with UCD.

Very low birth weight infants have increased nutritional needs. Extra nutrients are added to their human milk feeds to help improve their nutritional status, growth and neurodevelopment. Standard fortification of human milk is routine in most neonatal units in North America, but despite the added nutrients, infants are often discharged from hospitals with poor growth, and their neurodevelopment remains suboptimal. Two individualized fortification methods, target and BUN adjustable, have been proposed to improve the nutrient supply to infants. However, there is currently insufficient evidence to support the implementation of individualized fortification or one method over the other. Therefore, this study will randomly assign very low birth weight infants to receive feeds fortified according to standard, target or BUN adjustable fortification methods until 36 weeks gestational age or hospital discharge whichever occurs first. Feedings will be prepared in milk preparation rooms to ensure caregivers and outcomes assessor remain blinded to feeding allocation. Growth, morbidities, and nutrient intakes will be determined throughout hospitalization and skinfolds assessed at 36 weeks. At 4 months CA, growth and body composition will be determined by air displacement plethysmography and processing speed by electroencephalography on a subset of infants. Neurodevelopment will be assessed using the Bayley Scales of Infant and Toddler Development, at 18-24 months CA.

The main outcome determinant following cardiac arrest is hypoxic ischemic brain injury. Management has involved increasing the delivery of oxygen to the brain. This logic assumes that oxygen transport from blood into the brain is normal. We have demonstrated that this assumption is not true. A large proportion of post-cardiac arrest patients demonstrate an inability to unload oxygen into the brain. The mechanisms explaining this observation are unclear. This project involves using a series of evaluations to differentiate post-cardiac arrest patients who exhibit normal and abnormal oxygen transport dynamics and also investigate the underlying mechanisms for abnormal oxygen transport.

Although there have been substantial advances in the treatment of heart disease, heart attacks remain one of the leading causes of death and suffering around the world. Each year, more than 80,000 patients are hospitalized with heart attacks or related conditions in Canada. Even after discharge, patients are at high risk of having complications such that almost one in two patients after a heart attack will be readmitted to hospitals within the first year. Given the shortage of doctors and allied health care professionals, there is an emerging focus of digital health as a way to improve the care and outcomes after heart attacks. With more than 30 million cell phone users across Canada and almost all are already using text message services, the goal of this study is to conduct a pilot test using an innovative clinical trial design to see if the care and outlook of heart attack patients using mobile text messages can be improved.

Accidental falls in older adults are one of the world's major pubic health problem, because of their strong association with injuries and mortality rates. In Quebec, falls are responsible for a high rate of hospitalization (more than 1800 emergency department visits every day) and deaths (more than 10,000 in recent years). Preventing falls is therefore a key mission for health professionals. This research program aims to develop a new clinical approach to the rehabilitation management of the older with a neuro-musculoskeletal disorder and a risk of falling. This program is part of a new partnership project between UQAC and specialized geriatric services at the CIUSSS Saguenay-Lac-St-Jean (La Baie site). These geriatric services admit more than 400 new patients per year, representing a large pool of participants for the new program's development. Specifically, this program has 4 phases: 1) Create a clinical profile of patients in rehabilitation care from specialized geriatric services (ex: reasons for consultation, neuro-musculoskeletal disorders, rates and causes of falls, etc.); 2) to diagnose functional deficits of these patients on different dimensions of functional and physical evaluations, using standardized tests and high-tech instruments (ex: platform of force); 3) determine the effectiveness of a new exercise intervention program (OTAGO) for falls prevention; and 4) Measure client and professional team satisfaction as well as long-term impact of this new approach used to prevent falls. The most significant impact of this new program will be to reduce public health expenditure for care of older adults with balance disorder and risk for falls; and therefore, be implanted in other CIUSSS institutions from Quebec.

The study design is a cohort study with a propensity score-matched control group and difference-in-difference analysis to evaluate intervention effectiveness. A hybrid type 1 effectiveness-implementation study framework is used that incorporates mixed methods to determine clinical effectiveness and explore implementation and participant well-being. Participants are selected based on their utilization of health services. Selection favoured those individuals with the most health service utilization. A control group will be created by selecting individuals from administrative hospital records that are propensity-score matched to the individuals in the treatment group (1:4 pair). The hybrid type 1 effectiveness-implementation study framework was used to guide the selection of study aims and outcomes to focus primarily on clinical effectiveness, while also exploring implementation-related factors. The primary objective of the study is to evaluate the impact of the Initiative on the number of emergency department visits and days spent in the hospital. The secondary objectives are to 2) evaluate the impact of the Initiative on program participants' health and well-being, 3) evaluate the implementation of the Initiative and assess program fidelity and barriers, and 4) to calculate the cost avoidance and cost-effectiveness of the Initiative.

This is a randomized, double-blind, placebo-controlled, multicenter study to evaluate the effects of NMRA-335140 (formerly BTRX-335140) on symptoms of depression in participants with Major Depressive Disorder (MDD). The study design consists of a Screening Period (up to 28 days), and a 6-week Treatment Period (during which participants will receive either NMRA-335140 or placebo). At the completion of the 6-week Treatment Period, participants who complete the study, provide informed consent, and meet the eligibility criteria may enter an open-label extension study (NMRA-335140-501).

The use of titanium dental implants has become a common modern treatment to restore teeth. Although the success rate of dental implants is high, inflammation around the dental implant still occurs. The current study will investigate if the inflammation around the implant is due to bacterial infection, hypersensitivity or both.
