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.
Heart failure is a clinical syndrome marked by breathlessness, even at low levels of exertion, general fatigue, and fluid retention and is estimated to affect 5.1 million people in the United States. Heart failure with preserved ejection fraction (HFpEF) means that the heart pumps enough blood to the body, but patients still have terrible symptoms. It is estimated to account for about 50% of all heart failure cases. Experts agree that impaired filling of the heart, perhaps due to "stiffness" of the heart muscle itself, critically underlies HFpEF. There is currently no clinical technique for measuring heart muscle (myocardial) stiffness; the very definition of "myocardial stiffness" remains poorly established. Consequently, the ability to study the mechanisms that underlie HFpEF is virtually non-existent, and limited treatment options will persist without significant advances. The objective of this project is to use an Equilibrium-Material-Stability (EMS) framework that couples patient-specific clinical MRI and heart pressure data in a computational model of the heart to diagnose changes in myocardial stiffness. The central hypothesis is that the new EMS framework for understanding the mechanisms of diastolic dysfunction in HFpEF will be more sensitive and outperform currently available approaches.
Burn surgery is associated with significant reductions in hematocrit. However, it is unclear whether these reductions are the result of hemodilution from non-red cell containing intraoperative transfusions or from loss of red blood cells. The investigators will be using the Daxor Blood Volume Analyzer (BVA-100), an FDA approved instrument that can measure total blood volume, plasma volume, and RBC volume using the indicator dilution technique. By comparing pre-operative measurements of blood volume, plasma volume, and RBC volume to that of post-operative measurements after burn surgery, the investigators can determine the primary cause of the reduction in hematocrit associated with burn surgery. The investigators hypothesize that these reductions in hematocrit are primarily the result of hemodilution rather than blood loss and that there will be a statistically significant difference in measured plasma volume from the pre-operative group to the post-operative group.
The purpose of the study is to see if a commercially available hearing assistance device called the PockeTalker has an effect on performance on cognitive (memory and thinking) tests among skilled nursing facility residents. Investigators are asking residents to perform cognitive tests with and without hearing assistance equipment known as PockeTalkers. This study will be conducted at one urban Skilled Nursing Facility (SNF) with the goal of understanding the extent to which hearing impairment impacts commonly used cognitive impairment measures for clinical assessment. Cognitive performance will be measured, cerumen occlusion, and perceived hearing.
The FLX-787-106 study will determine how well FLX-787-ODT works to reduce fasciculations in patients with Amyotrophic Lateral Sclerosis (ALS). The study will measure how often fasciculations occur, and monitor any side effects that might develop while taking the investigational product. Participants will be assessed before and after taking a single dose of FLX-787-ODT. Approximately 15 people will take part in this study at one center in the United States. Participants will be in the study for a single clinic visit and receive a telephone call 7 days later to monitor for side effects.
Patients at least 18 years of age will be enrolled in the study to assess the efficacy and tolerability of Picato gel in the treatment of molluscum contagiosum. Patients must have an immunocompromised condition due to taking immunosuppressive drugs or having an inherited disease affecting the immune system.
To assess the safety and clinical effectiveness of using the FDA cleared HyGIeaCare System to relieve constipation in patients not responding to standard laxative treatment. Each patient will serve as their own control by comparing their bowel habits in a diary 4 weeks prior to colon irrigation to the bowel habits in their diary 4 weeks post colon irrigation.
The researchers are trying to see whether contrast-enhanced ultrasonography, shear wave elastography, strain imaging, and 3-D volume ultrasonography improves arterial wall visualization and identifies arterial elastic properties among individuals with fibromuscular dysplasia (FMD), atherosclerosis, personal history of spontaneous coronary artery dissections (SCAD), or personal history of segmental arterial mediolysis (SAM) that may be different compared to those without the aforementioned conditions.
A single-arm, open-label study to assess the overall safety of rovalpituzumab tesirine in participants with relapsed or refractory delta-like protein 3 (DLL3) expressing small cell lung cancer by evaluating the frequency of high grade (>= Grade 3) select treatment-emergent adverse events (TEAEs).
This study is examining the effects of the 2940 nm Er:YAG on atrophic facial acne scars under optical coherence tomography in terms of blood flow, vessel shape, skin roughness, collagen content, and epidermal thickness.
Objectives 1. Establish an induced pluripotent stem cell (iPSC) bank for phenotypically well-characterized patients with NF1. 2. Develop isogenic NF1 wild-type (NF1+/+), NF1 heterozygous (NF1+/-) and NF1 homozygous (NF1-/-) iPSC lines from individual patients using CRISPR/CAS9 technology. 3. Differentiate and characterize disease-relevant brain cells such as excitatory and inhibitory neurons, astrocytes and oligodendrocytes from patient-specific iPSC lines. 4. Screen and identify the drug(s) that can reverse or alleviate the disease phenotypes.
