NCT01908348
This study is an open-label pilot designed to examine the dose-dependent effects of erythritol, a zero calorie sweetener, on endothelial function. Twenty-four subjects with type 2 diabetes mellitus will make three study visits. At each visit, the will consume an orange-flavored beverage containing escalating amounts of erythritol (6, 12, and 18 grams). Endothelial function will be assessed before and two hours after beverage consumption. Endothelial function will be measured as the change in pulse amplitude in response to reactive hyperemia measured in the fingertip by peripheral arterial tonometry. The results will be used to plan a randomized, placebo-controlled study.
NCT01565161
While childhood obesity rates may have plateaued in some US population subgroups, such as whites and those of higher socioeconomic status, overall rates of obesity remain high and racial/ethnic and socioeconomic disparities appear to be widening. Among the most promising approaches for childhood obesity prevention and management are interventions that begin early in life and that support change at the individual and community levels. The goal of this project is to develop and test an intervention delivered to racial/ethnic minority and low income parents of 2-5 year old children in their homes, designed to promote adoption of household routines and parenting strategies that are preventive of obesity. To achieve this goal, the investigators will work with community health centers in Boston, Cambridge, and Somerville to recruit families to participate in an individual-level randomized controlled trial. The investigators partner community health centers include the Roxbury Comprehensive Community Health Center, Dimock Community Health Centers, and the Cambridge Health Alliance (CHA). Participants will be randomized to receive either 1) mailed educational materials for the duration of the 6-month program (control), or 2) home-based health coaching visits and phone calls with a health educator, text messages, and educational materials promoting the adoption of household routines and target behaviors (intervention). The investigators goal is to evaluate the feasibility and effectiveness of the investigators designed intervention (as compared to the control condition) using baseline and post-intervention data. In order to do so, the investigators will assess change from baseline to post-intervention in the investigators key behavioral outcomes of interest, including adoption of three household routines: 1. Regularly eating meals together as a family 2. Obtaining adequate sleep 3. Limiting screen-viewing time
NCT01504945
Patients with a low blood count (anemia) with stable or unstable coronary artery disease consistently show worse clinical outcomes. It is unclear whether this association is confounded since anemic patients tend to be also sicker i.e. have lower ejection fractions or more comorbidities and this would be the reason for the worse outcomes rather than anemia. The coronary arteries are a unique vascular bed insofar that across the cardiac circulation oxygen extraction is close to maximal at rest. Thus increases in demand can only be met by increases in blood flow and hemoglobin concentration since oxygen extraction is maximal at rest. It is natural to assume that maximization of oxygen delivery in the setting of active coronary syndrome (ACS) is beneficial to the patient since oxygen extraction and coronary blood flow is fixed. In fact, in most intensive care units patients with ACS are transfused to a HCT of 30%. However, retrospective analysis of trial data showed at best mixed results in clinical outcome when patients with ACS were transfused and in fact in some studies showed consistently worse outcomes than non-transfused patients. Similar disappointing results have recently published in patient who underwent coronary artery bypass grafting (CABG). This study is designed to determine the effect of red blood cell (RBC) transfusion on oxygen consumption, cardiac, microcirculatory and endothelial function in patients with active coronary artery disease. For this study active coronary artery disease will be defined as the patient having undergone within the past 4 days of recruitment either a myocardial infarction due to atherothrombosis (AHA type I myocardial infarction) or surgery for coronary artery bypass grafting. In specific this study will test the hypothesis whether RBC transfusions improves cardiac and vascular function in patients with a hematocrit of less than 30% with active coronary artery disease. Aims of this study are to determine whether RBC transfusion in patients with active coronary artery disease and anemia: * increases oxygen delivery to the peripheral tissues. * increases whole-body oxygen consumption. * decreases nitric oxide bioavailability, endothelial, microcirculatory, and myocardial function, and/or increases platelet aggregation
NCT01384799
This is a phase I dose escalation study of CUDC-101 in combination with concurrent cisplatin and radiation therapy in patients with locally advanced head and neck cancer.

NCT01966991
This study will explore how maternal plasma circulating cell free DNA (ccfDNA) can be used as a primary screening test for Down syndrome as part of routine clinical care in the general pregnancy population. Plasma ccfDNA testing is currently recommended only for use as a secondary screen for 'high-risk' women (i.e., women whose risk factors for trisomy make them candidates for invasive testing such as chorionic villous sampling or amniocentesis). Because most women in this 'high-risk' category are carrying unaffected fetuses, many 'unnecessary' procedures are completed in order to identify the few women whose fetuses have a chromosomal disorder. This creates expense, anxiety, and most importantly, loss of unaffected fetuses due to procedure related miscarriage. Plasma DNA testing is now being used to reduce significantly the number of women with unaffected fetuses undergoing invasive testing. Applying such testing as a 'first-line' screen has not been well-explored, despite calls from several clinical professional societies to do so. The investigators intent is to introduce, under carefully monitored conditions, ccfDNA testing through Rhode Island primary prenatal practices to the general pregnancy population. Education/orientation of prenatal care providers, their staffs, and their patients will be carefully orchestrated, and implementation issues identified and addressed. Telephone surveys of consented patients will elicit responses to their understanding of the test, their satisfaction with the process, and a comparison of their experience with serum screening in a prior pregnancy. Knowledge gained from this study will help validate new screening paradigms involving ccfDNA testing. The study is not designed to estimate Down syndrome detection rates with any confidence, but can provide information on uptake rates, failure rates, screen positive rates, and the decision-making of women with positive test results.

NCT01972529
This is a global, multicenter, randomized, double-blind, placebo-controlled, parallel group study using avatrombopag to treat adults with thrombocytopenia associated with liver disease. The study will evaluate avatrombopag in the treatment of thrombocytopenia associated with liver disease prior to an elective procedure to reduce the need for platelet transfusions or any rescue procedure for bleeding due to procedural and post-procedural bleeding complications. Participants will be enrolled into 2 cohorts according to mean baseline platelet count and, within each baseline platelet count cohort will be further stratified by risk of bleeding associated with the elective procedure (low, moderate, or high) and hepatocellular carcinoma (HCC) status (Yes or No).
