RADICAL PC1 is a prospective cohort study of men with a new diagnosis of prostate cancer. RADICAL PC2 is a randomized, controlled trial of a systematic approach to modifying cardiovascular and lifestyle risk factors in men with a new diagnosis of prostate cancer.

This is an open label, phase I/II, multi-center study in adult participants with metastatic hormone sensitive prostate cancer (mHSPC) and with metastatic castration resistant prostate cancer (mCRPC) who have received prior anti-cancer treatment and have a positive 68Ga-PSMA-11 PET scan. The purpose of this study is to learn if the study drug, \[225Ac\]Ac-PSMA-R2, is safe and tolerable, and has anti-tumor activity in treated patients.

This study is conducted in two phases. The phase 1 portion of the study evaluates the safety, tolerability, pharmacokinetics (PK), recommended phase 2 dose (RP2D), and effectiveness of lurbinectedin monotherapy in pediatric participants with previously treated solid tumors. This is followed by the phase 2 portion, to further assess the effectiveness and safety in pediatric and young adult participants with recurrent/refractory Ewing sarcoma.

RV dysfunction has been associated with increased mortality in the ICU and cardiac surgical patients. Thus, early identification of RV dysfunction at less severe stages will allow for earlier intervention and potentially better patient outcomes. However, so far, no studies have reported prospectively the prevalence of abnormal RV pressure waveform during cardiac surgery and in the ICU. The investigator's primary hypothesis is that the prevalence of abnormal RV pressure waveform occurs in more than 50% of cardiac surgical patients throughout their hospitalization. Those patients with abnormal RV pressure waveform will be more prone to post-operative complications related to RV dysfunction and failure in the OR and ICU.

The Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ) is a large international collaboration to develop algorithms using a set of clinical and cognitive assessments, multi-modal biomarkers, and clinical endpoints that can be used to predict the trajectories and outcomes of individuals at clinical high risk (CHR) for psychosis and to advance the testing of pharmacological interventions for CHR individuals in need. The goal is to accurately predict which individuals are likely to remit, experience an acute psychotic episode, or have intermediate outcomes that feature persistent attenuated psychotic and/or mood symptoms along with functional impairment. The prediction algorithms will have the potential to serve as early indicators of treatment efficacy in CHR persons. The AMP SCZ research program is made up of the Psychosis Risk Evaluation, Data Integration, and Computational Technologies - Data Processing, Analysis and Coordination Center (PREDICT-DPACC) and two clinical research networks, the Psychosis-Risk Outcomes Network (ProNET) and the Trajectories and Predictors in the Clinical High Risk for Psychosis Population: Prediction Scientific Global Consortium (PRESCIENT) networks. The two clinical research networks will recruit a large cohort of CHR young people aged 12-30 years (n=1,977) and healthy control (HC) participants (n=640) across 42 participating investigative sites from 13 countries. CHR participants will complete screening, baseline assessments and a battery of follow-up assessments across 18 - 24 months. HC participants will complete screening and baseline assessments and a subset (5 per site) will complete month 2, 12 and 24 visits.

The prospect of disease-modifying therapies in the pipeline for Alzheimer's Disease (AD) has intensified efforts to use brain imaging more effectively for diagnosis and monitoring of dementing illnesses. There is also emerging awareness of the destructive interplay between AD and Cerebrovascular Disease (CVD) in our aging population; both disorders share common vascular risk factors and may respond to similar prevention treatments. Brain mapping techniques capitalize on the fact that different neurodegenerative diseases target particular brain areas. Brain shrinkage and stroke disease can be quantified on Magnetic Resonance Imaging (MRI) using computerized analysis. This ongoing study applies advanced MR imaging analysis, genetic testing and standardized cognitive and functional assessments done at yearly intervals to measure and monitor longitudinal change in patients with AD, vascular and other neurodegenerative diseases and potentially to measure modifying effects of emerging therapies. Over 1700 patients (Mild Cognitive Impairment or dementia from AD, Vascular, Frontotemporal or Lewy Body Disease) and 140 normal elderly have already been enrolled, with 180 autopsies. This study utilizes specialized imaging analysis software packages to reliably quantify brain tissue volumes and small vessel disease, the most common type of CVD. The SDS also investigates other potential biomarkers of dementia such as eye-tracking, optical coherence tomography, gait and balance, and the gut microbiome to explore their clinical utility. Results from this study will help to improve diagnosis, to customize treatment, and to better monitor disease-modifying therapies currently under investigation should they become applicable to everyday practice.

The purpose of this study is to learn about the study medicine called elranatamab.This study aims to compare elranatamab to other medicines for the treatment of MM (a type of cancer). This study is seeking participants who: * Are 18 years of age or older and have MM. * Have received treatments before for MM. * Have MM that has returned or not responded to their most recent treatment. Half of the participants will receive elranatamab. The other half of participants will receive a combination therapy selected by the study doctor. The selected combination therapy will include 2 to 3 different medicines commonly used to treat MM. Elranatamab will be given as a shot under the skin at the study clinic about once a week. This may change to a smaller number of shots later in the study. The medicines in the combination therapy will be taken by mouth (at home or at the study clinic) AND will be given either as: * a shot under the skin at the study clinic * through a needle in the vein at the study clinic The number of times these medicines will be taken depends on what combination therapy the study doctor selects. Participants may continue to receive elranatamab or a combination therapy until their MM is no longer responding. The study team will see how each participant is doing with the study treatment during regular visits at the study clinic. The study team will continue to follow-up with participants after study treatment with telephone contacts (or visits). The study will compare the experiences of people receiving elranatamab to those people receiving a combination therapy. This will help learn about the safety and how effective elranatamab is.

This study will assess the safety and effectiveness of the SAPIEN 3/SAPIEN 3 Ultra transcatheter heart valve (THV) in patients with a failing aortic bioprosthetic valve.

The goal of our proposed multicentre prospective cohort study is to characterize perioperative usage patterns of crystalloids and albumin, as well as key patient outcomes, in cardiac surgical patients. Results obtained from this observational study will be combined with the results of other studies to clarify the optimal role of albumin and other blood products in the perioperative management of cardiac surgical patients. This study will also address numerous other knowledge gaps in the area of perioperative blood product management and fluid administration in cardiac surgery and define a collaborative group to support future research in this field.

Frailty describes the variability in aging and explains why two people of the same chronological age may look very different. Higher frailty leads to poor quality of life, disability, and death. Hospitalized patients living with frailty have a higher risk for functional decline, new impairments in activities of daily living, a longer hospital stay, hospital readmission, and death. A previous study from our team has reported that 60% of inpatients have more difficulty with 1+ basic activity of daily living (i.e., eating, getting out of bed, using the toilet, etc.) after hospitalization compared to pre-admission, with 1-in-4 patients having difficulty with 3+ basic tasks. Patients with few health deficits can recover to their pre-admission level, but those with higher frailty levels cannot, priming them for readmissions. Physical activity and reducing time spent sitting or lying postures prevent and improve frailty. Older patients who walk at least once/day outside their room during hospitalization have \~1.7 days shorter length of hospital stay compared with those who stayed in their room. Although multiple barriers exist to promoting upright time in a hospital, strategies that help address patients' excessive time spent in bed are often not implemented but could attenuate the development of frailty in the hospital. Few exercise interventions in hospital studies have considered frailty. The investigators have conducted a clinical trial within the Halifax Infirmary (Nova Scotia Health) that focused on mobilizing patients (average age: \~75 years) via regular visits by a Kinesiologist and observed that the intervention groups reduced their frailty level from preadmission and admission versus discharge. While preliminary findings from this model were promising, its reach was limited to acute geriatric care and dependent upon researchers to conduct the intervention. At the Georges-L. Dumont hospital, a patient mobilization program has been introduced in General and Internal Medicine (floor 4C) that embedded Kinesiologists within care to visit patients daily. Preliminary findings indicate that patients and staff are enjoying the program via self-report questionnaire. However, evaluations of the program's effectiveness in changing objectively measured activity and frailty levels and whether multiple patient visits would be more effective (e.g., refining the program) are unclear. The investigators propose to evaluate the effectiveness of the existing patient mobilization program and if more patient contact improves outcomes. Our study integrates activity monitoring technology and frailty assessments to help patients leave the hospital healthier and decrease the risk of readmission. Study Objectives: The proposed study will test the hypothesis that, compared to usual care (Kinesiology visit once/day), patients who receive multiple check-ins will, 1) increase their step counts and upright time, 2) decrease their frailty level, and 3) have a less length of stay and less readmission rates.
