There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Until now, diagnosis of constriction was based on pressure changes of ventricle by conventional pressure-wide hemodynamic evaluation but not on ventricular volume change. This study will provide answers to persisting questions about volume changes during respiration in patients with constrictive pericarditis by directly measuring both right and left ventricular volume.
There are approximately 1.4 million cesarean deliveries in the United States each year, and an average of 1250 elective cesarean deliveries each year at the Brigham and Women's Hospital (BWH) in Boston, Massachusetts. Among cesarean deliveries performed at BWH, approximately 2% of patients are diagnosed with a surgical site infection (SSI). Because SSI is associated with significant morbidity and increased cost of care, numerous guidelines exist to guide preoperative administration of prophylactic antibiotics. However, there are no recommendations for the choice of antiseptic solution for prevention of SSI. Among the currently popular antisepsis preparations, chlorhexidine-alcohol (CA) is known to decrease SSI in non-obstetric surgeries. However, the time required for CA to dry (~ 3 min) to minimize flammability risk is disadvantageous in the setting of emergent cesarean delivery. Many institutions use povidone-iodine, another antisepsis preparation that does not require the mandatory drying time. Our randomized study aims to compare the incidence of SSI in patients receiving either CA or PI during elective cesarean delivery, and we hypothesize that CA would be associated with a lower incidence of SSI.
The primary purpose of this pilot study is to evaluate the efficacy and safety of Abatacept in subjects with Sjogren's Syndrome (SS). This clinical trial study will enroll and treat 15 subjects with active moderate and severe inflammatory arthritis associated with primary Sjogren's syndrome (pSS) and secondary Sjogren's sybdrine (sSS) with Rheumatoid Arthrits (RA). All subjects will receive Abatacept weekly by Subcutaneous (SC) dosing. Subjects will receive Abatacept by SC injection of 125 mg on day 1 and followed by 125 mg SC weekly thereafter.
A research study to determine if heart failure can be medically managed using data collected from cardiac monitoring devices
The purpose of the study is to learn more abou how the immune system responds to the chickenpox vaccine in adults who had never had chickenpox as a child and were then vaccinated as an adult. The study aims to learn more about the strength and duration of the protection provided by the vaccine in adults, and to observe the immune response to an additional dose of chickenpox vaccine in adults who had received the vaccine at least 5 years earlier. This is especially relevant to workers in a hospital who may be exposed to chickenpox.
The purpose of this study is to help the researchers understand if using a soy supplement impacts cardiovascular disease risk factors in patients with subclinical hypothyroidism.
There has been a significant increase in the number of prescriptions being filled for Custom Compounded Pain Creams. This study serves to evaluate the patient perception and satisfaction with this type of pain therapy allowing us to identify any statistically relevant relationships that may exist between this type of therapy and patient pain perception. A secondary goal would be to identify any significantly relevant relationships that may exist between this change in pain perception (if any) and the patients overall sense of well-being. The investigators' null hypothesis is that greater that 85% of people will see an significant decrease in perceived pain levels and greater than 85% increase in patient overall sense of well being.
Smartphone applications (apps) may be well-suited as a low cost adjunctive tool for increasing the adherence of individuals to psychotherapy treatments which may subsequently increase symptom reduction and improve clinical outcomes. Apps offer the opportunity for real-time tracking of behavior and have the ability to provide prompt feedback and reminders in a convenient, readily available technology. The immediacy and convenience of apps may be responsible for the observed improvements in adherence on the part of the patients relative to traditional paper-and-pencil tracking and practice of skills taught in psychotherapy. These features are relevant to behavioral activation (BA) protocols, the effects of which are often attenuated by failure to adhere to regular practice and tracking of behavior. The Mood Coach app is a BA protocol developed to provide a convenient means of planning and tracking activity, and monitoring mood responses to scheduled increases in activity. This project evaluates the utility of this app as an adjunct to standard BA treatment. The investigators predict that participants assigned to the BA+app condition will demonstrate greater adherence to the BA treatment compared to the standard BA condition. The investigators also predict that the participants in the BA+app condition will report greater satisfaction with the app compared to the standard BA protocol that utilizes paper and pencil materials.
This will be an open-label, non-randomized multi-center study of adipose stem cell (ASC) implantation. ASCs will be derived from the patient's adipose or fat. Liposuction using local anesthesia and syringe collection will be performed to collect the adipose tissue specimen for subsequent processing to isolate the stem cells. The cells will be delivered via needle injection into the eye.
This is a single-site, open-label, phase II trial of C7, a food supplement or medical food, for the development of treatment outcome measures for glucose transporter type I deficiency (G1D). The primary outcome measures are: 1. Safety and tolerability of C7 as measured by changes in comprehensive blood work, including lipid and free fatty acid panels, self-reported side effects and clinical exam; 2. Changes in brain metabolic rate by MRI and EEG measurements during C7 treatment; and 3. Maintenance of ketosis in G1D patients on ketogenic diet, as measured by serial ketone levels during treatment initiation.
