People with non-small cell lung cancer are at risk for nutritional deficiencies. The purpose of this study is to find out what effects a nutritional product has on patient's response to immunotherapy or combination of immunotherapy and chemotherapy. To do this, some of the participants will get the nutritional product and some will receive a placebo (a substance that looks like the study drug but does not have any active or medicinal ingredients). A placebo is used to make the results of the study more reliable. Participants will be randomized to any of the following treatment groups: - Group 1 (Experimental intervention): standard intervention of immunotherapy or combination of immunotherapy and chemotherapy plus the experimental intervention nutritional product. Group 2 (Non-experimental intervention): standard intervention of immunotherapy or combination of immunotherapy and chemotherapy plus the non-experimental intervention placebo product. Participants will take 5 capsules each day by mouth, starting on the first day of immunotherapy with or without chemotherapy and stopping upon completion of their immunotherapy with or without chemotherapy treatment. Participants will complete a diary of their nutritional/ placebo product intake and will undergo the following assessments: * Physical examination. * Height and weight. * ECOG status (the physician will record the impact on the cancer on daily living abilities). * Concomitant medications recording. * Adverse Event Assessment * Computed tomography (CT) scan. A series of x-rays of the body from many angles that are turned into 3-dimensional pictures on a screen. * Quality of life questionnaires. * Blood collection

Over 18The main objective of this study is to compare the diagnostic performance of two diagnostic methods, namely CESM and MRI, in the evaluation of a lesion suspicious of breast cancer in 300 Quebec women referred for the investigation of breast cancer. breast lesion suspected of cancer. All suspicious lesions will be evaluated by these two diagnostic imaging and by TNM. Then, radiologists will respectively interpret diagnostic imaging, without knowing the result of the other imaging in parallel with the study. The sensitivity, specificity, positive predictive value and negative predictive value for his diagnostic imaging will then be determined. Histopathological confirmation by biopsy or surgery will be used as a standard value.

Over 18It can be challenging for Primary Healthcare Providers (PHCPs) to differentiate between IBS and more serious illnesses involving the GI tract, such as Crohn's disease, ulcerative colitis, or cancer. To help with diagnosis and treatment of IBS, evidence-based guidelines have been developed. However, they are not commonly used in primary care practice and PHCPs and patients often feel that GI specialist evaluation and endoscopy is required. The development of care pathways and clinical practice guidelines is essential to support the investigation and management of digestive diseases, such as IBS. The current pilot study is designed to assess the implementation and early comparative effectiveness of a Clinical Care Pathway for lower GI tract symptoms.

AnyRecovery after lung transplantation (LTx) may be complicated by prolonged mechanical ventilation (MV) and protracted intensive care unit (ICU) stay leading to immobilization and impaired health-related quality of life (HRQoL). In the critical care setting, diaphragm atrophy and weakness have been associated with difficulty weaning from MV, increased risk for readmission to hospital or ICU, and increased mortality. Increasing respiratory muscle strength by inspiratory muscle training (IMT) as part of pre-rehabilitation mitigates respiratory muscle dysfunction peri-operatively and may reduce the risk of post-operative complications. However, IMT is not widely used prior to LTx and the benefits of pre-operative IMT on post-transplant outcomes in LTx candidates have not been studied. Objectives: 1) To evaluate the feasibility of a randomized clinical trial of IMT in LTx candidates in terms of recruitment rate, retention, program adherence, safety and outcome ascertainment. 2)To establish whether IMT improves pre-transplant dyspnea perception, diaphragm structure and function, HRQoL and post-transplant ICU, hospital and 3-month outcomes. 3)To characterize the effect of pre-transplant IMT on peri-transplant diaphragm myofibrillar cross-sectional area, oxidative capacity, inflammatory markers and diaphragm muscle thickness and function. Methods: Prospective study of 50 LTx candidates recruited from the pulmonary rehabilitation program at University Health Network (UHN). Participants will have baseline evaluations of maximal inspiratory pressure (MIP), dyspnea, respiratory muscle endurance, diaphragm thickness and thickening fractions, as well as health-related quality of life questionnaires. After baseline assessments, participants will be randomized to the two study groups: IMT or usual care. IMT will be progressed weekly (max of 70% total MIP) until transplant. Participants will have repeat assessments (from baseline) at 4,8 and 12 weeks and then every 3 months until transplant (final assessment 3 months post-LTx).

Over 18Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing fast track programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing ambulatory TKA, and its effects on patients' quality of recovery. Investigators hypothesize that continuous adductor canal block would lead to decrease in opioid consumption in patients undergoing fast track TKA. Significance There are no published prospective randomized controlled trials to assess patient's reported quality of recovery after receiving CACB in same day primary knee arthroplasties. As this is a frequent type of surgery and has the prediction to increase its incidence for the next years, there is significant importance in investigations about interventions which may improve its recovery in a fast track regime. A postoperative analgesic technique that offers better pain control, has less adverse effects, reduces the opioid analgesia requirement and is safe to be used in a fast track setting may have additional impact on decreasing health care cost and may lead to an enhanced recovery and better quality of life. Objectives To evaluate effectiveness and safety of using CACB in patients undergoing ambulatory TKA, in comparison to SACB. Primary objective is opioid consumption (in oral morphine equivalent doses) Secondary objectives are to evaluate postoperative QoR-15 scores (10), pain scores, opioid-induced adverse effects (measured via validated opioid symptom distress scale), postoperative functional status, complications relating to the perineural catheter and readmissions.

Over 18The current standard of care approach for programming cochlear implants uses a generalized pitch-map for all patients. This approach fails to account for individualized inner ear anatomy. As a result, many cochlear implant recipients experience place-pitch mismatch. We have recently developed an automated mathematical tool to produce patient-specific, customized cochlear implant pitch-maps (Helpard et al., 2021). In this study, cochlear implant recipients will be randomized to receive either the clinical default pitch-map (the control group) or a place-based pitch-map (the intervention group). Assessments will be conducted at multiple time-intervals to account for patient acclimation and plasticity to both the generalized and individualized pitch-maps. Audiological assessments will be tuned to identify patients' ability to discern pitch scaling and variation in sounds, as well as to understand complexities in speech such as mood and tone. Audiological testing will be conducted in collaboration with the National Centre for Audiology (London, ON) to ensure that the most accurate and relevant metrics are applied.
