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.
This study is a clinical trial to assess the efficacy and confirm the safety of intratumoral inoculation of G207 (an experimental virus therapy) combined with a single 5 Gy dose of radiation in recurrent/progressive pediatric high-grade gliomas
Fibrinolysis is the body's process that prevents blood clots. The investigators hypothesize that patients presenting with acute pulmonary embolism (PE) or blood clots in the lungs differ in their fibrinolytic deficit phenotype. The investigators aim to use biomarkers directly involved in endogenous fibrinolytic cascade including PAI-1, Alpha-2-Antiplasmin (A2A), TAFI, D-dimer, and Fibrinogen to phenotypically characterize patients presenting with acute PE and to correlate these biomarkers with clinical, echocardiographic, computed tomography (CT), and functional status outcomes.
The investigators are doing this study and medical record review to measure simultaneous pressure and volume of the heart called pressure volumes loops before and after ventricular assist device placement for cardiogenic shock ( a severe form of heart failure). Standard of care measurements will be the sole measure of clinical determination. The investigators are measuring these PV loops to help determine which patients heart have recovered and can have the ventricular assist device removed. The investigators are also using the PV loop to indicate/correlate with certain outcomes to predict the need for LVAD patients to require additional support in the form of a right ventricular assist device. The medical record review will be performed pre-operatively, intra-operatively, and post-operatively until the day of discharge.
Background: The Calcium-Sensing Receptor (CaSR) detects the amount of calcium in the blood and urine. Parathyroid hormone (PTH) helps keep blood calcium levels normal. When PTH and calcium blood levels are low, this is called hypoparathyroidism. People with changes in the CaSR have a type of hypoparathyroidism called ADH1. ADH1 is treated with calcium supplements and vitamin D. But these do not always work, and can cause problems like kidney stones. Researchers want to see if the drug CLTX-305 is a better treatment option. Objective: To see if CLTX-305 is safe and works in people with ADH1. Eligibility: People ages 16 and older with ADH1 Design: Participants will be screened with: Medical history Physical exam Kidney ultrasound: Participants will lie on a table while a wand is moved over their back. Bone density test: Participants will lie on a table while an X-ray machine moves around them. Blood, urine, and heart tests The study is split into 3 periods. Participants may take part in some or all periods. In Periods 1 and 2, participants will take CLTX-305 by mouth once or twice daily for up to 5 days. Participants will stay at the NIH for 7 days and 6 nights. In Period 3, participants will take CLTX-305 at home for 24 weeks. They will have 3 inpatient visits that last 1 2 days each. Screening tests will be repeated during the study. Blood and urine will be collected often. Participants dose of calcium and vitamin D may be changed. They may be asked to stop taking other medicines or change the dose.
This study will provide access to investigational anti-SARS-CoV-2 human convalescent plasma for pediatric patients with underlying medical conditions (cardiovascular disease, lung disease, immunosuppression) who are either infected with SARS-CoV-2 or who have had a high-risk exposure. Study participants will be transfused once with compatible convalescent plasma obtained from an individual who has recovered from documented infection with SARS-CoV-2. Safety information and pharmacokinetic data will be collected.

The central objective of this study is to validate new algorithms that coordinate between functional electrical stimulation (FES) and the exoskeleton during sitting-to-standing, walking, and standing-to-sitting movements. The secondary objective is to optimize the algorithms as well as assess their ability to reduce FES-induced muscle fatigue by using ultrasound imaging as a sensing modality. This study will include persons with no disabilities and persons with Spinal Cord Injury (SCI). A research set-up comprising of a lower-limb exoskeleton and FES system will be used to achieve sitting-to-standing, walking, and standing-to-sitting movements. Ultrasound Imaging probes may be used to record muscle activity of the stimulated muscles. The signals derived from ultrasound will be used to optimize FES in order to reduce muscle fatigue as well as assess muscle fatigue.
This study is a prospective, single center, observational, cohort study of patients to (1) describe the kinetics and temporal relationship of changes in eicosanoid and cytokine mediators in patients with severe COVID-19 admitted to the hospital; and (2) correlate the dynamic changes in eicosanoid mediators with available patient clinical status, including measures of severity of illness, routine laboratory tests, and outcomes.
The purpose of this research study is to determine whether using aromatherapy during chemotherapy infusion treatments in the outpatient Oncology setting promote relief of nausea and anxiety. The objectives of this study are: 1. To promote relief of nausea using peppermint aromatherapy oil in an outpatient oncology setting. 2. To promote relief of anxiety using lavender aromatherapy oil in an outpatient oncology setting.
This is a phase 2 open-label, 6 arms (1 study group and 1 control group for each joint category), randomized control group clinical study with 300 subjects diagnosed with osteoarthritis of knees (n=100), hips (n=100) and shoulders (n=100). The study subjects will be evaluated for disease-associated severity according to symptoms, such as pain, mobility, daily active life, and functions using arthritis society established specific measurement tools related to the joints (KOOS and KSS for OA-knees: HOOS and HHS for OA-hips and ASES and CSS for OA-shoulders).
