Septic shock is associated with substantial burden in terms of both mortality and morbidity for survivors of this illness. Pre-clinical sepsis studies suggest that mesenchymal stem (stromal) cells (MSCs) modulate inflammation, enhance pathogen clearance and tissue repair and reduce death. Our team has completed a Phase I dose escalation and safety clinical trial that evaluated MSCs in patients with septic shock. The Cellular Immunotherapy for Septic Shock Phase I (CISS) trial established that MSCs appear safe and that a randomized controlled trial (RCT) is feasible. Based on these data, the investigators have planned a phase II RCT (UC-CISS II) at several Canadian academic centres which will evaluate intermediate measures of clinical efficacy (primary outcome), as well as biomarkers, safety, clinical outcome measures, and a health economic analysis (secondary outcomes).
Single center prospective study to analyze the impact of diabetes mellitus on patients' outcome following radiofrequency-guided catheter ablation for atrial fibrillation.
Background: Recurrent respiratory papillomatosis (RRP) is a rare disease that causes wart-like growths in the airways. These growths come back when removed; some people may need 2 or more surgeries per year to keep their airways clear. Better treatments are needed. Objective: To see if a drug called bevacizumab can reduce the number of surgeries needed in people with RRP. Eligibility: People aged 18 and older with recurrent RRP; they must need surgery to remove the growths in their airways. Design: Participants will be screened. Their ability to breathe and speak will be evaluated. They will have an endoscopy: a flexible tube with a light and camera will be inserted into their nose and throat. They will have a test of their heart function and imaging scans of their chest. Participants will have surgery to remove the growths in their airways. Bevacizumab is given through a small tube placed in a vein in the arm. After the surgery, participants will receive 11 doses of this drug: every 3 weeks for 3 doses, and then every 6 weeks for 8 more doses. They will come to the clinic for each dose; each visit will be about 8 hours. Tissue samples of the growths will be collected after the second treatment; this will be done under general anesthesia. Participants may undergo apheresis: Blood will be drawn from a needle in an arm. The blood will pass through a machine that separates out the cells needed for the study. The remaining blood will be returned to the body through a second needle. Follow-up will continue for 1 year after the last treatment.
Over the past 10 years, the rates of multiple sclerosis (MS) have nearly doubled in the United States. This chronic, neuroinflammatory, and neurodegenerative disease is most often diagnosed between the ages of 20-40. Cognitive impairment effects up to 70% of people with MS (PwMS) and has a detrimental impact on mental health, social connections, and employment. Further, up to 50% of PwMS also struggle with depression. Numerous cognitive rehabilitation programs are available to address cognitive impairment, but few interventions have simultaneous effects on cognition and emotional well-being. Music interventions have potential to fill this gap. Brain imaging studies on music and emotion show that music can modulate activity in the brains structures that are known to be crucially involved in emotion. Further, music engages areas of the brain that are involved with paying attention, making predictions, and updating events in our memory. The purpose of this study is to determine the feasibility of an online musical training intervention (MTI) for PwMS and explore the potential effect on cognition, psychosocial, and functional well-being compared to an active control group (music listening (ML)). The specific aims are to: 1) determine the feasibility and acceptability of delivering the MTI virtually over three months to PwMS; 2) evaluate the effect of the MTI on cognitive functioning (processing speed, working memory, cognitive flexibility, response inhibition), psychosocial (anxiety, depression, stress, quality of life, self-efficacy) and functional (insomnia) well-being compared to ML; and 3) (exploratory aim) to utilize non-invasive neuroimaging to determine if pre-intervention brain activity predicts post-intervention cognitive functioning.
This is a placebo-controlled clinical trial to assess whether Guanfacine Extended Release (GXR) reduces aggression and self injurious behavior in individuals with Prader Willi Syndrome (PWS). In addition, the study will establish the safety of GXR with a specific focus on metabolic effects.
Parkinson's disease (PD) is a progressive neurological disorder characterized by motor and non-motor symptoms such as rigidity, bradykinesia, resting tremor, cognitive and autonomic dysfunctions, gait and balance difficulties. The impairment of gait, balance and cognitive performances is partially responsive to dopaminergic medications. This emphasizes the importance of non-pharmacological interventions for people with PD (pwPD). Intensive multidisciplinary motor and cognitive rehabilitation has been proposed as a complementary and effective treatment for managing pwPD. Several structural and physiological mechanisms have been suggested to underpin exercise-induced neuroplastic changes in PD, such as enhanced synaptic strength and preservation of dopamine neurons. To date, studies on brain changes induced by motor and cognitive exercises in pwPD have been small-scaled and uncontrolled. Identifying accessible and measurable biomarkers for monitoring the events induced by intensive motor and cognitive rehabilitation program would help in testing the treatment effectiveness and would allow personalization of rehabilitation strategies by predicting patients' responsiveness. Based on validated clinical assessments of intensive multidisciplinary rehabilitation treatment, the project will test the ability of a new set of biomarkers to evaluate rehabilitative outcomes in a cohort of people with PD.
Patient-centered novel e-health technology and services will lay the foundation for future healthcare systems and services to support health and welfare promotion. Yet, there is a lack of ways to incorporate novel technological innovations into easy-to-use, cost-effective and low workload treatment. The detection of atrial fibrillation (AF) paroxysms and its permanent form as well as the prevention of AF-related strokes are major challenges in cardiology today. AF is often silent or asymptomatic, but the risk of ischemic stroke seems to be similar regardless of the presence or absence of symptoms. CARE-DETECT algorithm development part I will investigate following topics: 1. The usefulness and validity of bed sensor and mobile phone application in rhythm disorder capture compared to gold standard ECG-holter monitoring (Faros ECG) 2. Accuracy of AF detection from PDL data 3. Technical development of algorithms to detect arrhythmia from data collected with these novel devices 4. Development of a pre-processing tool that will evaluate the collected data and generate a preliminary filtered report of the raw data to ease clinician's workload in data handling and rhythm evaluation. CARE-DETECT clinical trial (part II) proposal provides a new concept for low workload for healthcare personnel, high diagnostic yield in silent AF detection and AF burden evaluation. CARE-DETECT protocol proposal seeks to address following issues: 1. Can a combination of actively used smartphone application and passive monitoring with bed sensor (with upstream ECG) - compared to routine care - enhance the detection of AF in patients who are at increased risk of stroke and have undergone a cardiac procedure? 2. What is the actual AF burden in paroxysmal AF patients after the detection of new-onset AF? 3. Can a direct-to-consumer telehealth with integrated cloud-based telecardiology service for medical professionals improve the efficacy of silent AF detection and what is the AF burden in patients suffering of (asymptomatic) paroxysmal AF and secondarily what is the cost-effectiveness of these new screening methods? 4. Additionally, during the hospitalization phase of the study part II PDL data will be collected in the intervention group. PDL data will be analyzed offline with the purpose to develop new methods and will not be used to monitor treatment or for diagnosis.
PacePress medical device, by ensuring constant compression force and the ability to optimize it in the pocket area prevents/significantly reduces the risk of hemorrhagic complications, including but not limited to the operation pocket hematoma. By avoiding a strong localized compression and ensuring "covering compression" achieved by the appropriate distribution of compression forces on the entire implantation site area, with an automated compression force control, the risk of a pressure sore created in the compressed pocket area is reduced.
This study will compare an Amygdala and insula retraining (AIR) program to an internet therapy developed at Helsinki University Hospital. The study will be a multi-center randomized controlled trial. Study units will be recruited from the Network for Functional Disorders that is hosted by the HUS Clinic for Functional Disorders and potentially later from international collaborators. The trial will clarify whether internet-based non-drug based therapies are helpful in overcoming the central sensitization and the functional disabilities caused by these disorders.
