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.
Coronary artery blockages can reduce blood flow to the heart muscle. Fractional flow reserve (iFR or FFR) assessment is an invasive tool used to determine how much blood flow is reduced. The investigators will perform iFR/FFR on all intermediate coronary stenoses using standard practice, immediately before (at the time of) transcatheter aortic valve replacement (TAVR) and after successful TAVR. The investigators will compare pre- and post-TAVR iFR/FFR values, and assess short-term outcomes. The investigators hypothesize that iFR/FFR values will be consistently and significantly higher pre-TAVR in comparison with post-TAVR for the same lesions.
This research is being done to learn more about the differences in engaging, recruiting, linking and adhering to pre-exposure prophylaxis (PrEP) services for men who have sex with other men at risk for HIV in Baltimore City. In 2012, the U.S. Food and Drug Administration (FDA) approved the use of Truvada as pre-exposure prophylaxis (PrEP) to help prevent HIV infection. In the intervention, a virtual, PrEP Care Anywhere Telemedicine approach supported by virtual peer-navigator will be compared to standard clinic-based PrEP services with face-to-face peer navigation. The study will evaluate whether PrEP Care Anywhere, which is more patient-centered, will improve adherence and retention in PrEP care.
This study seeks to implement and evaluate a data-driven case navigation system for hepatitis C virus (HCV) treatment among persons who are either actively injecting drugs or who are receiving opioid substitution therapy (OST). The study will use data from a previously developed patient registry system to identify patients for study recruitment, and use monthly updates of registry data to organize and direct patient navigation services for those individuals assigned to the treatment group. Patients assigned to the control group will also be eligible to receive HCV treatment, but will otherwise receive usual care. This study has a parallel, randomized unblinded, case/control design in which eligible patients are assigned at baseline to either a registry-directed patient navigation system (case) or to usual care (control), characterized in terms of demographic and sub-population variables, and then compared after 12 months on two categories of outcomes; (1) attainment of care cascade milestones; and (2) treatment initiation, adherence, and virologic response. The study is designed and powered to answer two primary hypotheses (H1 & H2): - H1: As compared to those randomized to usual care (control), those randomized to the registry directed patient navigation arm (case) will be more likely to complete all pretreatment HCV care milestones as defined by a higher proportion completing all four pre-treatment care cascade outcomes. - H2: As compared to the control group, a significantly higher proportion of those randomized to the case group will achieve a sustained viral response.
The goal of this study is to identify effective ways to assess the patient and family experience. Specifically, the study will examine automated administration of the Child Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) Survey on the day of discharge through an electronic interactive patient care system. The will be a multisite study that will take place at Boston Children's Hospital (BCH) as well as at several other hospitals across the United States.
The primary objective of this feasibility study is to determine if administration of LUM015 will result in positive fluorescence of tumor tissue from ex vivo specimen imaging with the LUM Imaging device from patients undergoing radical prostatectomy for prostate cancer. Both normal tissue and tumor tissue will be imaged and analyzed. The LUM Imaging System is a portable combination product consisting of an imaging device and an imaging agent (LUM015). Patients with an established diagnosis of prostate cancer and who are eligible for radical prostatectomy will be screened. Eligible patients will be enrolled and on the day of their planned surgery, LUM015 will be administered 2-6 hours prior to surgery. Patients will undergo radical prostatectomy 2-6 hours after LUM015 administration. All surgical specimens will be imaged with the LUM imaging device and have routine diagnostic assessment. Patients will be monitored for adverse events from time of injection through the first standard of care post-surgical follow-up visit.
The study will enroll 5 individuals post-stroke to examine the feasibility and efficacy of a high frequency repetitive transcranial magnetic stimulation (rTMS) combined with body weight supported treadmill training.
Obtaining intravenous access (IVA) is the most common procedure performed in the emergency department (ED). Placement of IVA allows for blood work and delivery of intravenous fluids and medications. The implementation of ultrasound guided peripheral IVs (UGPIV) have allowed for ultrasound to be used to place an IV into patients with difficult vein access (DVA). An alternative device to place is a midline catheter (MC). The use of MCs against UGPIV has not been compared in a randomized study. Aim 1: To determine if UGPIVs have a higher failure rate than midline catheters within 72 hours of placement. Aim 2: To collect information to perform a direct cost analysis of UGPIV against that of the midline catheter. Aim 3: Assess patient satisfaction.
The primary goal of this study is to assess whether ventilation of deceased organ donors with an open lung protective ventilatory strategy will improve donor lung utilization rates and donor oxygenation compared to a conventional ventilatory strategy.
This is a randomized, double-blind, placebo-controlled study in patients with dilated cardiomyopathy (DCM) due to a mutation of the gene encoding the lamin A/C protein (LMNA). The study will further evaluate a dose level of study drug (ARRY-371797) that has shown preliminary efficacy and safety in this patient population. After the primary analysis has been performed, eligible patients may receive open-label treatment with ARRY-371797.
This is a study primarily comparing Magnetic Resonance Imaging (MRI) alone to Positron Emission Tomography (PET)/MRI using an experimental tracer, 68Ga-PSMA-HBED-CC, among men with prostate cancer or prostatic cancer recurrence/metastasis. It is hypothesized that this comparison will demonstrate that PET using the tracer, 68Ga-PSMA-HBED-CC, is more sensitive than MRI alone. Potential subjects who cannot undergo MRI may undergo PET/CT instead.
