Filter by:Adults with serious mental illness (SMI) frequently have unmet medical needs which place them at risk for adverse health outcomes. While there are proven ways to manage and/or prevent serious medical conditions common among this population, information is needed to understand their impact on outcomes that matter most for patients, particularly in community mental health centers (CMHCs) where most adults with SMI receive their care and rural areas where locating and receiving health care services can be challenging. The investigators will test two promising ways for promoting the health, wellness, and recovery of adults with SMI. One way will help patients manage their health and health care through self-management strategies, including the use of a web portal, and peer support (patient self-directed care) and the other through interactions with nurses during clinic visits (provider-supported integrated care). The investigators will compare the two interventions on three primary patient-centered outcomes (i.e. patient activation in care, health status, engagement in primary/specialty care). The investigators hypothesize that: 1. Patient self-directed care will result in improvement in patient activation. 2. Provider-supported integrated care will result in greater improvement in frequency in primary/specialty care visits. 3. Both interventions will result in significant improvements in the three primary outcomes. The investigators will collect information from patients, caregivers, and clinic staff at different points in time during the study. Patients will be asked to complete questionnaires and additional data on their service use will be gathered. Some patients and providers will also be interviewed about their experiences with care. The investigators will examine these data to learn if, how, and why the new services improve outcomes over time. This information will help us understand patient and other stakeholder views about the services and, if appropriate, ensure their continued and/or expanded availability.
The primary objective for this study is to prove the safety and effectiveness of the Spectranetics Turbo-Elite catheter in atherectomy treatment for infrainguinal arteries with catheter to vessel sizing of at least 50%.
Double-blind, randomised, placebo-controlled, parallel group study with two intervention arms. The study will be conducted in 150 subjects and the primary objective is to show a fasting LDL-cholesterol and triglyceride lowering effect of plant sterols in subjects with established type 2 diabetes mellitus and subjects at high risk of developing type 2 diabetes.
The objective of this study is to evaluate the performance of the Zilver PTX stent thumbwheel delivery system.
25-30% of women with preexisting vascular disease (chronic hypertension/diabetes/obesity) will develop pre-eclampsia and or growth restriction. In addition, the frequency of stillbirths in this group is dramatically increased over the general population. Pregnancy complications in this very heterogeneous group are likely to be a combination of a failure of the maternal vasculature to adapt to pregnancy and/or a failure of placental development. The relative contribution of these two mechanisms is poorly understood and current preventative strategies (aspirin) in this group only prevent a small number of adverse outcomes. This important and complex group have been inadequately investigated to date mainly because of the diversity of their underlying disease complicating prospective research studies. The evolution of tools which allow more detailed assessments of both uteroplacental blood flow and maternal vascular function will enable us to perform prospective studies in these women and to develop targeted preventative measures. Recent biomarker studies have also identified a number of biomarkers which have not yet been assessed in these high risk groups.
The purpose of this study is to investigate the prevalence of signs and symptoms of hypogonadism in three groups of testicular cancer survivors.
Collect confirmatory evidence of the safety and effectiveness of the Balloon LIFESTREAM™ Stent Graft for the treatment of stenoses and occlusion in the iliac arteries.
The purpose of this study is to assess the safety, efficacy, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of OMS721 in patients with thrombotic microangiopathies (TMA).
The purpose of this clinical study is to test whether or not patients treated with HBOT for diabetic foot ulcers will demonstrate measurable changes of the blood vessel function during the course of HBOT treatments. , i.e. an expected increase in the reactive hyperemic index (RHI) measured by the peripheral arterial tonometry (PAT).
The purpose of the study is to measure RV ejection fraction (RVEF), pulmonary flow, and pulmonary perfusion before and after exposure to inhaled nitric oxide in patients with pulmonary arterial hypertension (PAH) who are known to be vasodilator-responsive based on invasive catheterization as well as healthy subjects. Measurements will also be made after high flow oxygen alone to test the relative vasodilatory effect of oxygen and NO. The investigators hypothesize is that inhaled nitric oxide during cardiac MRI can be used to measure dynamic changes in RV-pulmonary vascular function in patients with vasodilator-responsive PAH.
