Randomized study of medication withdrawal in patients who have recovered LV function in Dilated Cardiomyopathy.
The objective of this study is to utilize information on associations between genetic predisposition pertaining to multiple single nucleotide polymorphisms (SNPs) and the degree of responsiveness of low-density lipoprotein cholesterol (LDL-C) lowering to plant sterols (PS). The predictive potential of SNPs associated with PS responsiveness will be evaluated using a randomized human intervention trial examining responsiveness of lowering blood LDL-C levels to PS intervention.
Capillary Malformations (CM) affect a significant proportion of otherwise healthy children and may lead to psychological discomfort if left untreated. A significant proportion of untreated lesions undergo soft tissue thickening and darker discoloration later in life due to progressive ectasia of the affected vessels. While laser treatment is available, its use may be limited due to need for repeated sedation/general anesthetic use, partial response and cost. The investigators propose to conduct an open-label, prospective, cohort study using Onreltea ( Brimonidine) gel for treatment of facial capillary malformations in children. The study medication will be applied topically on affected area of the skin daily for 12 weeks. Follow up visits will occur at at Week 1,4,8,12, and 16 to assess the efficacy and safety of the proposed treatment. The study second aim is to explore the feasibility of conducting a multicenter placebo controlled study.
Epidural analgesia is commonly used for labor pain relief due to its safety and effectiveness. Despite a very high success rate, the epidural technique remains a somewhat blind technique and failures continue to occur. Unfortunately, there are no imaging techniques that can be used at the bedside to determine the proper positioning of the epidural catheter. The trans-catheter electric stimulation test (TCEST) has been successfully used for this purpose. This test is occasionally performed in situations where the immediate confirmation of the proper epidural catheter location is deemed necessary. The test helps to predict which epidurals might fail so that appropriate measures could be immediately implemented. There has been one duration of electrical stimulus (0.2 milliseconds) that has been used in the majority of studies and in clinical practice. With this duration of stimulation, the vast majority of cases show a unilateral motor response of the lower limbs during the TCEST. Studies on the stimulation of peripheral nerves (nerves in the arms and legs) have shown that an electrical stimulus with a longer duration is able to stimulate nerves which are farther away. Since nerves in the epidural space are similar in composition to peripheral nerves, the investigators expect to see a higher rate of bilateral response with the longer duration of stimulus. The investigators also hope to show that this bilateral response is predictive of a better functioning epidural. The investigators hypothesize that the incidence of a bilateral response to the TCEST will be higher with the 1.0 ms pulse width compared to 0.1 ms pulse width. Furthermore, the investigators hypothesize that a bilateral motor response associated with the 1.0 ms pulse width will be predictive of symmetry of sensory and motor block and of lower consumption of local anesthetic.
The main purpose of this study is to investigate the safety and efficacy of the study drug solanezumab in participants with prodromal Alzheimer's disease (AD).
This trial will compare two strategies for patients with Heart Failure, Left Ventricular systolic dysfunction, and intermediate QRS durations. The control group is conventional CRT. The experimental group is LVendo CRT
Patients with bone marrow cancer are more susceptible to chest infections than healthy adults; marrow ablation treatment further compromises their immune status and increases the risk of fungal opportunistic infection, which is associated with a high fatality rate. Therefore, it is critical to achieve early and accurate diagnosis of fungal infection when these patients become febrile. At the Mount Sinai Hospital (MSH) and the University Health Network (UHN), the standard of care (SOC) to exclude a chest infection in immunocompromised (IC) patients is chest computed tomography (CT) using low dose CT (LDCTT).
Some medications taken by the breastfeeding women are excreted into milk, posing a potential risk of toxicity to the infant. The first line of evidence required for toxicity risk assessment is prediction of drug levels in milk. However, pharmacokinetic (PK) information of drug excretion into milk is largely lacking, or limited to data from case reports. This makes it difficult to provide population-level prediction of drug levels in milk. The lack of data on this topic jeopardizes not only maternal adherence to drug therapy during breastfeeding but also establishment of breastfeeding, even if the drug is considered safe during nursing. Clearly, this clinical problem in drug safety is an important women's health issue, affecting both mother and infant. "Drugs in Lactation" Analysis Consortium (DLAC) is a "drug-in-milk" monitoring network, which is designed as a platform for efficient collection of patient milk samples in a real world setting to generate population predictions of drug excretion levels into human milk.
Background: Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is the third most common cardiovascular disorder after myocardial infarction and stroke. VTE occurs in about 1 person per 1,000 per year, increasing dramatically in patients with cancer to about 25 per 1,000 per year. Among the known risk factors of VTE, cancer is one of the most potent. Patients with cancer have a 7- to 28-fold higher risk for VTE than non-cancer patients. VTE has important implications for the care of cancer patients, including reduced life expectancy, high rates of VTE recurrence both while on and after stopping anticoagulation, the need for chronic anticoagulation with related adverse drug reactions, and delays in cancer therapies. Clinical dilemma: Current clinical guidelines recommend a minimum of 3-6 months of anticoagulation with weight-adjusted low molecular weight heparin (LMWH) in cancer patients with VTE. However, there are no recommendations beyond the initial 6 months of therapy due to the lack of data on extended duration therapy for cancer-associated thrombosis (CAT). This leads to variability in physician practices, with some continuing weight-adjusted LMWH therapy beyond 6 months. This poses concern because, while the goal is to prevent recurrence of VTE, the risk of major bleeding with prolonged weight-adjusted LMWH therapy is significant. Potential solutions: There is a lack of data to inform on VTE treatment in cancer patients beyond the initial 3-6 months of anticoagulation. We propose that after a minimum of 3-6 months of therapeutic dose anticoagulation, the use of prophylactic doses of LMWH will have an acceptable and adherence profile in cancer patients with VTE. The data obtained from this study will help inform physician practices. Design: This is a multicentre, open-label study of enoxaparin (40 mg subcutaneous injection, once daily) for additional 6 months after an initial minimum 3-6-month course of therapeutic dose anticoagulant therapy. Patients: 150 patients with VTE secondary to cancer will take part in this multicentre study conducted in 8 Canadian centres within Quebec, Ontario and Nova Scotia. Study Outcomes: The primary objective of the study is to determine the rate of recurrent VTE in patients receiving prophylactic dose enoxaparin for secondary VTE prophylaxis after an initial minimum 3-6 months of anticoagulation. The secondary objective is to determine the safety profile of prophylaxis dose enoxaparin for secondary VTE prophylaxis after an initial 3-6 months of anticoagulation. This includes determining for all subjects: 1) cumulative incidence of major bleeding events; 2) cumulative incidence of clinically relevant non-major bleeding events; 3) cumulative incidence of minor bleeding event, and 4) overall survival during follow-up.
