The objective of this project is to assess the effects of combined physical exercise and cognitive training interventions on cognitive and brain health in patients with heart failure (HF). Also, the role of sex on the effects of the interventions will be assessed. Read Less

This large real-world international prospective registry will provide a unique opportunity to comprehensively understand the contemporary management, clinical course and short as well as long-term outcomes of all Cardiogenic Shock (CS) patients cared for at four high volume dedicated shock care centers. As the first true North American multicenter CS collaborative with a uniform dedicated and comprehensive case report form, the high patient volumes and wide spectrum of clinical acuity seen at these institutions will provide valuable insight into the factors associated with adverse outcomes; and will serve as a blueprint for future clinical trial designs that may better inform clinical practice.

Participants will be asked to wear a continuous glucose monitor for at least three days on three separate occasions. One testing session will be a no-exercise resting control session (90 minutes). One will be a moderate aerobic exercise session (30 minutes of exercise, 60 minutes of recovery), and the third will be a moderate weight-lifting session (\~30 minutes of exercise, 60 minutes of recovery).The investigators will measure changes in blood glucose during exercise by drawing blood during and after exercise. Post-exercise glucose trends will be examined using continuous glucose monitoring. Read Less

In this study, the investigators are testing a new formulation of lidocaine for its suitability in managing postoperative pain after pelvic (circumcision, inguinal, scrotal), perineal (hemorrhoidectomy) or perianal (fistulotomy) incisions. The new formulation ST-01 is a sustained release lidocaine formulation and is expected to provide pain relief over multiple days. Currently, the drug lidocaine is not available as an injectable slow-release formulation. Read Less

Investigators know that many patients who are on dialysis suffer from burden of unwanted symptoms, which can affect quality of life. The understanding and treatment of symptom burden by healthcare providers is limited and should be recognized as a high priority in the care of the dialysis population. In this study, the investigators will be assessing symptom burden using the London Evaluation of Illness "LEVIL," an application based platform where patients self-report their symptoms with one to three hemodialysis treatments per week for 28 weeks. The investigators would like to compare the currently available dialyzer with a new dialyzer that is capable of removing solutes of higher molecular weight that may or may not cause patients to experience symptoms related to increased amounts of toxins in their blood.

This is a prospective, open-label, within-patient clinical trial to determine the accuracy of Indocyanine green (ICG) guided sentinel lymph node biopsy (SLNB) compared to the standard dual-tracer SLNB in breast cancer patients who have had chemotherapy as a first treatment using a non-inferiority design. Patients with operable breast cancer treated with chemotherapy and eligible for SLNB will be included in the study. During surgery, ICG will be injected and used to identify fluorescent sentinel nodes using a hand-held imaging camera; radiotracer and blue dye will also be used as per standard protocols. Intraoperative and clinicopathologic outcomes such as complications, characteristics of nodes, false negative rates and feasibility will be assessed. Patients will be asked to complete standardized patient reported outcome questionnaires (Breast-Q, FACT-B+4, VAS) to define the patient experience with this novel technique. Read Less

Spinal cord injury (SCI) has been shown to be associated with impairment to the autonomic nervous system in the form of reduced activity of a key nerve known as the vagus nerve. As the vagus nerve has an important role in regulating inflammation and is associated with depression, it may represent a key mechanism which contributes to chronic inflammation and depression following SCI. A technique known as transcutaneous auricular vagus nerve stimulation (taVNS) can stimulate the vagus nerve non-invasively through an electrode applied on the skin of the ear. This technique has been shown to effectively reduce inflammation and improve symptoms of depression in other populations without any serious adverse events. However, it has not been assessed in individuals with SCI. The primary objective of this study is to assess the efficacy of taVNS therapy for the treatment of inflammation and depression. Autonomic function as assessed by measures of heart rate variability (HRV) will also be assessed to quantify changes in vagal tone. The study will be conducted over a 2-year period, with 44 individuals with SCI and depression participating. Participants will be randomly assigned to receive either active taVNS or a placebo (sham) treatment over a 30-day period. The researchers will assess changes in depression symptoms, autonomic function (heart rate variability), and biomarkers related to inflammation at baseline and 30-days. Safety and adherence will also be evaluated to confirm the feasibility for long-term use. This study aims to explore a novel and non-invasive treatment strategy for depression in individuals with spinal cord injury. If taVNS is found to be safe, effective, and feasible for SCI patients, it could offer a simple, cost-effective way to address chronic inflammation and depression in this population. Read Less

Current medical treatment allows more people to survive heart attacks than in the past. However, some of the survivors suffer heart disease and require hospitalization later on. The causes behind this heart disease (heart failure) after a heart attack are poorly understood. Matrix metalloproteinase 2 (MMP-2) is a protein that cuts other proteins into pieces, and is activated in heart muscle when there is a heart attack. MMP-2 causes heart injury when the blood flow to the heart is restored after the attack. Blocking MMP-2 activity is a potential therapy to prevent heart injury under these circumstances. The only MMP-2 inhibiting drug currently approved for clinical use is doxycycline, specifically used to treat periodontitis (gum inflammation) and rosacea (a skin condition). At higher doses doxycycline also acts as an antibiotic for which it has been clinically used for decades. A previous clinical study found that taking doxycycline twice a day, for one week after a heart attack improved the health of the patients' hearts. The investigators have conducted a similar study in patients that had surgery to replace blocked coronary arteries (blood vessels that feed the heart muscle). These patients took a low dose of doxycycline once a day for 2 days before surgery, on the day of the surgery, and three days after surgery. The participants in this study showed no adverse effects of using doxycycline. The goal of this study is to see if doxycycline protects the hearts of patients that suffered a heart attack. All patients will receive standard clinical care for their condition, but in addition will take a doxycycline capsule twice a day, or a placebo capsule for 7 days, as soon as possible after being diagnosed with a heart attack. Three months later, the investigators will evaluate the patients by looking at their heart structure using magnetic resonance imaging (MRI). MRI is a powerful tool that allows doctors to see inside the body without surgery or X-ray radiation. The hearts of those patients that received doxycycline are expected to be healthier than those who received placebo. The investigators plan to promote the use of doxycycline to protect the hearts of patients with heart attacks. If successful, doxycycline could help improve the quality of life of heart attack survivors. Read Less

Patients with heart disease are often prescribed many medications and these patients may experience drug interactions or negative drug related side effects. With newer medications and treatments available, it is not well known whether older drugs, such as beta-blockers, are still an effective and safe option for treating heart disease. Some evidence suggests beta-blockers should be continued, whereas other evidence suggests beta-blockers might cause unnecessary harm. The study hopes to determine whether continuation or discontinuation of beta-blockers will affect long term cardiovascular outcomes. The study investigators will also examine how beta-blockers continuation or discontinuation affects several quality of life measures. Read Less
