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.
The primary goal of the present prospective cohort study is to evaluate the effect of varying incidences of BOP at implant sites across 15 months of maintenance visits on the probability of peri-implant disease progression. Over 15 months, participants will attend 6 visits where clinical measurements and maintenance care will be performed every 3 months.
The goal of this clinical trial is to assess long-term safety and efficacy of rusfertide in subjects with polycythemia vera. Subjects who complete dosing with rusfertide until the end-of-treatment visit of a Phase 2 or Phase 3 study and meet the inclusion/exclusion criteria for this study, are eligible to participate in this open-label study and continue treatment with rusfertide.
The purpose of this study is to evaluate the effect of an 8-week walking program on blood pressure in inactive older adults with respiratory impairment, a condition where lung function is sub-optimal for a person's age. Older adults with respiratory impairment have greater risks of death by cardiovascular disease (CVD) compared to those without respiratory impairment, and this may be partly driven by higher resting blood pressure. One way to lower blood pressure is to increase the number of daily steps achieved throughout the course of everyday life ('lifestyle steps'), and previous research shows that an additional 3,000 lifestyle steps/day is effective for achieving this. However, whether an increase in daily lifestyle steps is effective for reducing blood pressure in senior-community dwelling older adults with respiratory impairment is unknown. Understanding how increasing daily steps impacts blood pressure in this understudied population is important for informing future strategies for tackling cardiovascular disease risk in those with lung dysfunction.
The field of transcatheter tricuspid valve replacement (TTVR) is rapidly emerging and data on this topic are scarce. Particularly, little is known about which patients are at greatest risk of procedural complications, such as the timing and onset of conduction disturbances necessitating permanent pacemaker implantation, and how such patients are managed. On this background, the TRIPLACE Registry - an investigator-initiated global multicenter registry - is aimed at better understanding the safety and efficacy of orthotopic TTVR.
Spasticity is one of the most common symptoms manifested in humans with spinal cord injury (SCI). However, the neural mechanisms underlying the development of spasticity over time after an acute SCI are not yet understood. Using electrophysiological and imaging techniques along with traditional measurements of neurological recovery in the acute rehabilitation setting including physical exam and functional assessments; the investigators aim to examine the relationship between development of spasticity, residual descending motor pathways and functional and neurological recovery in humans with SCI from acute to subacute phase
Breast pain following second-trimester abortion is common. Breast engorgement and milk leakage following second-trimester perinatal loss and abortion can cause both physical pain and emotional distress. Dopamine agonists have previously been shown to be effective in lactation inhibition for third-trimester fetal/neonatal loss or contraindications to breastfeeding. The investigator's prior work demonstrated that compared to placebo, a single dose of cabergoline was effective in preventing breast symptoms after abortion or loss 18-28 weeks. As lactogenesis starts as early as 16 weeks gestation, the investigators hope to determine the efficacy of cabergoline earlier in the second trimester,16-20 weeks.
The purpose of this research is to further investigate the potential of brain stiffness as a novel biomarker for Alzheimer's disease.
The goal of this clinical trial study is to(1) determine the tissue specific dose of I-131 taken up by residing thyroid issue in the thyroid bed post-RAI along with any other sites in the neck and mediastinum as well as (2) correlate the dose delivered to residual tissues in the neck with patient follow-up based clinical outcomes, biochemical and imaging data following RAI therapy in patients with well-differentiated thyroid cancer (DTC). The main question[s] it aims to answer are: - [question 1] How can obtained whole body and planar images more adequately depict residual iodine-avid disease in the thyroid bed, neck or mediastinum? - [question 2] How can we obtain information on the dose taken up by the tumor remnant to know how much radionuclide actually went to the residual disease/tissue? Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items].
The primary purpose of this phase I/II study is to evaluate whether partially matched, ≥1/6 Human Leukocyte Antigens (HLA) -matched, viral specific T cells have efficacy against adenovirus, Cytomegalovirus (CMV), and Epstein Barr Virus (EBV) in subjects who have previously received any type of allogeneic Hematopoietic Cell transplant (HCT) or solid organ transplant (SOT) or have compromised immunity. Reconstitution of anti-viral immunity by donor-derived cytotoxic T lymphocytes has shown promise in preventing and treating infections with adenovirus, CMV, and EBV. However, the weeks taken to prepare patient-specific products, and cost associated with products that may not be used limits their value. This trial will evaluate viral specific T cells generated by gamma capture technology. Eligible patients will include HCT and/or SOT recipients, and/or patients with compromised immunity who have adenovirus, CMV, or EBV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.
Venous thromboembolism (VTE) causes up to 100,000 deaths annually. Between 10%-30% of patients die within one month of VTE diagnosis, while survivors remain at increased risk for VTE recurrence or other complications like post-thrombotic syndrome or chronic pulmonary hypertension in the following decade. Trauma patients have many risk factors that predispose them to a VTE. During the first 48 hours after blunt trauma, patients are prothrombotic due to the release of procoagulant factors, have excessive thrombin generation due to extensive tissue and vascular injury, and have reduced circulation of endogenous anticoagulants like protein C.
