Carpal tunnel syndrome (CTS) is the most common nerve compression syndrome worldwide, causing significant chronic pain, functional impairment, and lowered quality of life for individuals of various backgrounds. CTS is caused by chronic compression of the median nerve in the carpal tunnel of the wrist, causing numbness and pain in the palm, thumb, index, and middle fingers and eventual weakness of the hand. Many different treatments for CTS have been proposed and studied, including but not limited to non-operative treatments such as wrist splinting, steroid injections, and lifestyle modifications as well as operative treatments, such as surgical carpal tunnel release (CTR). To date, very few oral medications have been shown to be effective as conservative treatments for CTS. In this study the investigators will examine whether there is any benefit to using oral N-acetylcysteine (NAC) as an adjunctive treatment for mild to moderate CTS in addition to a standard 8-week trial of night splinting. NAC has been used in humans for various purposes, is extremely safe and has very few side effects, and has been shown to have anti-inflammation properties which may help treat CTS. The investigators will study this by performing a randomized controlled trial, comparing patients receiving oral NAC and standard night splinting to patients receiving an identical placebo and standard night splinting. Both patient groups will be assessed using a questionnaire to assess for severity of their CTS symptoms both before and after the 8-week treatment. The primary objective will be to determine whether supplementation with oral NAC in addition to night splinting has any significant impact on patient-reported symptoms and functional impairment when compared to night splinting alone. The investigators will also measure secondary outcomes including whether patients decide to have surgery for their CTS after treatment and/or continued use of other treatments. This study has the potential to have a significant positive impact on patients by identifying a safe, inexpensive, accessible, and well tolerated conservative treatment for mild to moderate carpal tunnel syndrome, and potentially preventing the need for additional, more invasive treatments such as surgery.

The role of cardiac mechanics, circulating biomarkers and frailty in predicting outcomes in patients with aortic stenosis after aortic valve replacement (SCRABLES -The 2-Parts Study) Part I: Observational study to characterize phenotypes, structural alterations and biomarkers profiles in a broad spectrum of patients with aortic stenosis and heart failure with preserved ejection fraction (HFpEF). Part II: Prospective cohort study to characterize patients' phenotypes, cardiac structural alterations, circulating biomarkers and frailty in order to optimize risk stratification and patient selection for aortic valve intervention.

Obstructive sleep apnea (OSA), which causes abnormal pauses in breathing during sleep, is common in patients with vascular cognitive impairment (VCI) and Alzheimer's disease (AD), and exacerbates the cognitive deficits seen in these conditions. OSA is typically treated with continuous positive airway pressure (CPAP), which has been shown to improve cognition in VCI and slow cognitive decline in AD. Despite the need to identify OSA in patients with VCI/AD, these patients often do not undergo testing for OSA. One major barrier is that in-laboratory polysomnography (iPSG), the current standard for diagnosing OSA, is inconvenient for patients with VCI/AD who may be reliant on others for care or require familiar sleep environments. A convenient and cheaper alternative to iPSG is home sleep apnea testing (HSAT), which has been validated against iPSG to diagnose OSA and has proven feasible for use in VCI/AD. Our primary objective is to determine whether the use of HSAT is superior to iPSG in terms of the proportion of patients who complete sleep testing by 6 months post-randomization. We will also investigate cost-effectiveness, patient satisfaction, proportion of patients treated with CPAP, changes in cognition, mood, sleep-related and functional outcomes between HSAT and iPSG at 6 months.

The study aims to establish lysine requirements using the indicator amino acid oxidation (IAAO) method in women exclusively breastfeeding a single infant aged 3-4 months, and how maternal lysine needs change once infant transition to complimentary feeding at a later age of 9-10 months. Each 8-hour study day will have an assigned test lysine intake ranging from deficient to excess. The diets will be provided in a complete protein shake format, meeting all nutrient requirements except for the test lysine intake. Breath samples evaluate the indicator's oxidation to determine protein synthesis in response to lysine intake. Urine and one blood sample will be collected to assess metabolite concentrations.

Fat tissue in different parts of the body has different characteristics. Several studies have associated abdominal fat to an increased risk for multiple metabolic diseases, such as type 2 diabetes and cardiovascular disease, compared with fat located under the skin at the hips and thighs. However, the investigators do not know how the abdominal fat causes or contributes to the development of these diseases or how the development of these disease may in turn cause or contribute to changes in the fat tissue. The general objective of this study is to understand these mechanisms. To investigate these questions, the study will recruit 140 participants, both men and women aged 18-65 years. The participants will be divided into three groups: 40 people with obesity, 40 with diabetes, and 60 lean individuals. Participants will be recruited from patients at the CIUSSS du Nord-de-l'Île-de Montréal - Hôpital du Sacré-Coeur de Montréal who are awaiting bariatric or general abdominal surgery, as well as from the general population in the Montreal area.

Patients are enrolled to screening (Reg Step 1) prior to or after ASCT but prior to Reg Step 2. Patients are followed until they will begin Maintenance and then registered to Reg Step 2 (first randomization). Patients are randomized between Lenalidomide for 2 years and Lenalidomide + Daratumumab/rHuPH20. After 2 years of Maintenance, MRD is assessed to guide further therapy. MRD-positive patients will continue with the assigned treatment. MRD-negative patients will be further randomized (Reg Step 3) to either continue or discontinue the assigned treatment. Patients are treated for up to 7 years from Step 2 reg and followed for up to 15 years.

ATTACH™ is a psycho-educational parenting program, designed with community agencies serving families of preschoolers affected by toxic stress (e.g. parental depression, addictions, domestic violence, poverty) to bolster children's health and development. It focuses on improving parent-child relationship quality by targeting parents' reflective function (RF), i.e. the ability to better understand one's own and one's child's thoughts and feelings. RF is essential for high quality parent-child relationships and secure attachment, both tied to child development and health, especially cognition, communication and inflammation. ATTACH™ was implemented and tested in seven rapid-cycling pilot studies by researchers, guided by the IDEAS (Innovate, Develop, Evaluate, Adapt, Scale) Framework™, an innovative clinical trial approach. ATTACH™ significantly improved: (a) parent-child relationship quality and attachment, (b) parents' RF scores, and (c) children's cognitive and motor development. However, whether ATTACH™ continues to work with delivery by trained agency healthcare professionals rather than study researchers, in naturalistic, community settings remains to be seen. Small sample sizes also limited the ability to assess longer-term impacts and whether ATTACH™ is equally effective across patient populations. Further, another parenting intervention successfully reduced systemic inflammation in children exposed to toxic stress. Whether ATTACH™ impacts novel biomarkers of inflammation (i.e. immune cell gene expression and DNA methylation) is not known.

The purpose of this study is to investigate and compare the feasibility and efficacy of two group-based interventions (education vs. mindfulness) to help self-manage Long-COVID symptoms.

Calcium Release Deficiency Syndrome (CRDS) is a novel inherited arrhythmia syndrome secondary to RyR2 loss-of-function that confers a risk of sudden cardiac death. Diagnosis of CRDS presently requires cellular-based in vitro confirmation that an RyR2 variant causes loss-of-function. We hypothesize that CRDS can be diagnosed clinically through evaluation of the repolarization response to brief tachycardia, mediated by cardiac pacing, and a subsequent pause.

Research indicates that individuals diagnosed with lung or esophageal cancer who enter treatment with higher functional capacities, improved body composition, and better nutrition status tend to experience better outcomes and a higher quality of life. The primary objective of a prehabilitation health coaching program is to enhance the overall health and well-being of patients before they undergo major surgery.This personalized 8-week program encompasses elements such as nutrition, smoking cessation, sleep hygiene, and movement, equipping participants with the knowledge and tools needed to adopt healthier lifestyles.
