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 goal of this study is to evaluate the effectiveness of a short-term (4 weeks) pharmacological blockade of sympathetic nerve activity (clonidine) on anxiety symptoms, vascular function, inflammation, muscle sympathetic nerve activity, and oxidant stress in individuals with moderate-to-high anxiety. Individuals who are interested in the study will be identified by an online screening survey and will be contacted by the research team; advertisements, flyers and mass emails will direct individuals to the online screening survey. Those deemed eligible to participate will be randomized to either the clonidine intervention or hydrochlorothiazide as a blood-pressure lowering control condition. If eligible participants are currently being treated with blood pressure-lowering medications, they will be asked to go off these medications for 2 weeks prior to and during the course of the study. During the 2 week washout of blood pressure-lowering medications, participants will have safety visits (2 additional visits) that include measurements of blood pressure at 4 days and 7 days after the beginning of the washout period before the intervention. Assessments of anxiety symptoms via various surveys, vascular function (via non-invasive, well-established techniques), inflammation, muscle sympathetic nerve activity, and oxidant stress will be performed at baseline and at the post intervention session. Similar baseline measurements will be performed in control subjects with low or no anxiety for comparison, but these individuals will not undergo the intervention. Participants with moderate-to-high anxiety will have a total of 6 visits to the laboratory, which includes the screening and consent (visit 1). Visit 2 (baseline measurements) and visit 6 (post-intervention measurements) will be more extensive (~4.5 hours) compared to the other visits (~30 min). Participants completing the washout will have an additional 2 visits (~30 min each) before "visit 2." Control subjects with low or no anxiety will only participate in visit 1 (screening and consent ) and visit 2 (baseline measurements).
The investigators will conduct a pilot randomized controlled trial (RCT) of Sisters-GPS with HIV-positive women of color with suboptimal ARV adherence and detectable HIV viral loads (VL). Participants will be randomized to Sisters-GPS (intervention involving weekly group clinical visits for seven weeks plus social media website) or appointment with an adherence counselor (a minimum of 3 visits) (control condition). Data sources will include interviews, medical and pharmacy records, and blood samples. The primary outcome will be ARV adherence at the completion of the intervention assessed via pill count. The secondary outcome will be HIV VL suppression.
Positive end-expiratory pressure (PEEP) is used in premature infants receiving mechanical ventilation to maintain lungs open and facilitate gas exchange. When ventilation/perfusion mismatch is present, areas of the lung that are open for gas exchange do not match up with areas of the lung that are receiving blood for gas exchange. This study measures the feasibility of enrolling and completing study maneuvers in premature infants for a prospective study measuring the responsiveness of V/Q mismatch to changes in the amount (or level) of PEEP.
The aim of this study is to substantially reduce overall postoperative morbidity and mortality associated with obstructive sleep apnea.
This randomized phase II trial studies how well a gluten free diet works in diminishing side effects in patients with acute myeloid leukemia undergoing induction chemotherapy. A gluten free diet may result in less intestinal side effects and blood infections during the induction chemotherapy compared to a standard diet.
To prospectively collect blood and tumor tissue from esophageal cancer patients to identify specific esophageal cancer mutations that can be measured in the blood (cell free DNA) during the course of treatment as a marker of response and recurrence.
This is a 68-week study to evaluate the long-term safety and efficacy of fremanezumab in participants with cluster headache (CH). Participants who complete the pivotal studies TV48125-CNS-30056 (NCT02945046) and TV48125-CNS-30057 (NCT02964338) and enroll into the current study will visit the investigational center for investigational medicinal product (IMP) administration, safety and efficacy assessments, and blood and urine collections for pharmacokinetics, immunogenicity (anti-drug antibodies [ADAs]), and biomarker analyses. Participants will return to the investigational center for a follow-up visit to evaluate ADAs, fremanezumab concentrations, biomarkers, and safety (adverse events and concomitant medications) approximately 7.5 months after the last dose of IMP.
To assess facial acne vulgaris clinical and psychological outcomes by measuring differences in lesions counts, investigator global assessment, and subjects quality of life scores over 6 months in adult females treated with Next Science™ acne cream 2x or Next Science™ acne cream 1x in a double blind manner.
The purpose of this study is to determine the best way to optimize the success of external cephalic version (turning the baby from the outside). Attempting to turn babies in-utero is recommended because it may decrease the risk of needing a cesarean section for abnormal presentation. While the study team knows that this procedure can be effective, the study team still has some un-answered questions as to the best way to perform this procedure to increase the chance of success. Many prior studies have shown that using spinal anesthesia (a shot of medication placed in your back to numb and relax the abdomen) can increase the success rate of a version. This ultimately has led to the finding that using this anesthesia can decrease the rate of cesarean section. However, there have been only a small number of studies assessing the success rate if spinal anesthesia is used only in the event that without it fails. Therefore the study team is going to compare patients who receive spinal anesthesia with those who only receive spinal anesthesia if the procedure to turn the baby (ECV) fails without it.
The goal of this clinical research study is to learn about the tolerability of nivolumab in patients who have bladder cancer, were previously treated with BCG immunotherapy, and who have a cystectomy (removal of all or part of the bladder) scheduled as part of their standard care. This is an investigational study. Nivolumab is FDA approved and commercially available to treat metastatic (has spread) melanoma or non-small cell lung cancer (NSCLC) after the disease has gotten worse while receiving platinum-based chemotherapy. The use of nivolumab in this study is considered investigational. Up to 10 participants will take part in this study. All will be enrolled at MD Anderson.
