NCT01850082
Coronary artery bypass grafting (CABG) is the most common major surgical procedure in the United States with over 300,000 cases performed each year. To restore blood flow to the heart, vascular conduits from another part of the body are procured to create a bypass around critically blocked coronary arteries. The left internal thoracic artery is the conduit of choice for CABG due to its superior long-term patency. However, almost all patients referred for CABG require additional grafts to provide complete revascularization. This necessitates the harvest of other vessels, most commonly the saphenous vein which is used almost ubiquitously in contemporary CABG with an average of two vein grafts per CABG procedure. In the last 10 years, Endoscopic Vein Harvesting (EVH) has been recommended as the preferred method over the traditional open harvesting technique (OVH) because it provides a minimally invasive approach. However, more recent investigations indicate potential for reduced long-term bypass graft patency and worse clinical outcomes with EVH. The long term impact of EVH on clinical outcomes has never been investigated on a large scale using a definitive, adequately powered, prospective Randomized Controlled Trial (RCT) with long-term follow-up.

NCT03996876
The investigators have developed a mobile app called Resolving Psychological Stress (REPS) to help alleviate symptoms of PTSD. The app will administer threat-related attention bias modification to individuals who have both a Diagnostic and Statistical Manual of Mental Disorders V (DSM-V) diagnosis of PTSD (and meet at least one DSM-V criteria for threat sensitivity) and a DSM-V diagnosis of Alcohol Use Disorder. The aims of the study are to explore both the feasibility and acceptability of the app with it's users, and to explore the efficacy of the app at alleviating PTSD severity.
NCT03065244
Kawasaki disease (KD) is a self-limited illness that affects the heart blood vessels (coronary arteries) of infants and children and is now the most common cause of acquired heart disease in children. A mixture of proteins from human blood (Intravenous immunoglobulin, IVIG) is a treatment that reduces the rate of the major complication of the disease: a bulging of the wall of the coronary arteries called an aneurysm. However, 10-20% of children are resistant to this treatment and the fever returns. These children have the highest rates of aneurysm formation and thus should be treated aggressively. Unfortunately, there are no guidelines for the best secondary treatment for these resistant patients because the problem has never been adequately studied. Most physicians choose either a second infusion of IVIG or an engineered antibody called infliximab that inactivates a molecule that promotes inflammation. This trial will randomize (assign by chance like the flip of a coin) IVIG-resistant patients to receive either a second IVIG infusion or infliximab and the response to treatment will be compared to learn which treatment stops the fever the fastest. In addition, parents and caregivers will provide observations about their child's response to the different treatments.
NCT02699086

NCT03177525
Children with autism spectrum disorder (ASD) exhibit characteristic deficits in social initiation and there are no empirically validated treatments specifically for this core deficit. While parent training is known to be a critical intervention component, few social skills programs involve parents. This study will capitalize on an existing social skills group already established at the community agency Abilities United, with the goal of enhancing the program's effectiveness by adding a parent component. Specifically, the proposed study will investigate whether a novel parent mediated social skills program (Social SUCCESS), which provides parent training in conjunction with a social skills group intervention, will result in more frequent initiations during play with typically developing peers. Participants will include 50 children with ASD age 4:0 to 6:11 years. Children will be randomly assigned to either Social SUCCESS (N=25) or waiting list (N=25). Treatment will be provided for 8 weeks during a weekly 120-minute social skills group at Abilities United. The study will evaluate the effects of Social SUCCESS on areas of core social deficit including frequency of peer initiations using parent ratings, observational measures, standardized questionnaires, and a social eye tracking task. Outcomes will be compared to a waiting list control group. Findings will be disseminated through presentations and publications to aid clinicians in providing more effective social skills treatment for children with ASD and to enhance the scientific knowledge-base related to evidence-based social skills treatments. This research designed with the goal of stimulating additional scientific inquiry in the area of treatment for core social deficits in ASD and will provide a strong foundation for larger scale grants to study motivation-based interventions to improve social functioning.
NCT01138189

NCT01118026
This research is being done in order to improve treatment outcomes in patients diagnosed with bulky, early stage Hodgkin lymphoma and to reduce the side effects that are associated with use of radiation used in current treatments. The chemotherapy treatment in this study consists of a combination of four drugs approved by the Food and Drug Administration (FDA): doxorubicin, bleomycin, vinblastine, and dacarbazine. This regimen (called ABVD) has been found to be effective in treating patients with Hodgkin lymphoma and is considered the standard of treatment used with radiation therapy in patients with bulky early stage Hodgkin lymphoma. As part of the evaluation of the effectiveness of the chemotherapy treatment, PET scans will be obtained during the course of therapy. The usefulness of this PET scan will be evaluated to determine whether radiation may be left out in the treatment of disease if the PET scan shows that the patient has responded to chemotherapy alone. The plan is to identify a group of patients using early PET scans in order to change to a chemotherapy treatment called BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone). It is one of the most highly effective chemotherapy regimens for Hodgkin lymphoma, but is associated with more side effects than ABVD. Although it has become standard of care in Europe, its use has been more limited in the U.S. because of concerns about toxicity.
NCT00988247
Subjects with perennial allergic rhinitis will be randomized to 320 mcg of beclomethasone dipropionate (BDP) using a hydrofluoroalkane (HFA) propellant or placebo as a nasal aerosol. The subjects will be followed for safety and efficacy for a period of 30 or 52 weeks. BDP HFA is a steroid which is currently FDA approved for the treatment of asthma. BDP-HFA should be safe and effective as a "dry" nasal aerosol which may be preferred by some patients.
NCT03283371

NCT01224106
This multi-center, randomized, double-blind, placebo-controlled parallel-group study will evaluate the effect of gantenerumab (RO4909832) on cognition and functioning and the safety and pharmacokinetics in participants with prodromal Alzheimer's Disease. Participants will be randomized to receive subcutaneous (SC) injections of either gantenerumab or placebo. Participants who consent to be part of the sub study will undergo positron emission tomography (PET) scanning to assess brain amyloid. The anticipated time on study treatment is 104 weeks in Part 1, with an option for an additional up to 2 years of treatment in Part 2, followed by an open-label extension (Part 3) until July 2020. The dosing for Parts 1 and 2 was stopped after a planned futility interim analysis showed a low probability of meeting the primary outcome measure with the doses studied. The study has converted to open-label to investigate higher gantenerumab doses.
