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.
Cerebrovascular diseases (CVD) and neurodegenerative diseases (NDD) are both leading causes of death in the United States. Epidemiological data have shown that increased prevalence of hypertension is related to these outcomes. However, despite the strong association of poor brain health outcomes in patients with hypertension (HTN), the understanding of cerebral blood flow (CBF) regulation and treatment options for HTN remain limited. Acupuncture treatment (AT), which is considered a promising complementary and integrative modality, has been known to reduce blood pressure and improve endothelial function in HTN. However, very few studies have investigated AT's effect on cerebrovascular function and the possible neuroprotective properties directly via regulating HTN. Exercise is used as a stimulus that increases the brain's metabolism and requires cerebrovascular responses (vasodilation) to meet the new metabolism. Therefore, the specific aim of this study is to test the hypothesis that an antihypertensive acupuncture treatment can acutely improve cerebrovascular responses in hypertensive humans during moderate exercise.
The goal of this clinical trial is to learn about the role of noradrenergic system in the non-motor symptoms of Parkinson's disease. The main objectives it aims to answer are: 1. To explore the association between orthostatic hypertension which is low blood pressure that occurs after going from lying to standing, and several neuropsychiatric and neurocognitive nonmotor features of Parkinson's disease (PD), such as feeling tired or disinterested and depression. 2. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring hormonal response to head up tilt-table testing before and after administration of yohimbine. 3. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring participants pupils before and after administration of yohimbine Participants will be asked to come onsite for two study visits. Visit one will consist of: - Discussing and signing the Informed Consent Form - Discussing Medical History and Current Medications - Collecting Blood samples - Measuring heart rate and blood pressure - Mental health screening and neurocognitive questionnaires - Pupil test - Test to feel vibrations Visit two will consist of : - Mental Health questionnaire - IV Placement - Blood Draws - Administration of Yohimbine hydrochloride - Head up tilt table - Measuring heart rate and blood pressure - Answering questions about anxiety, mood, and fatigue using a scale - Pupil tests Visit three will be a follow-up call from the Nurse Coordinator to discuss any adverse events.
Chemotherapy is a common strategy used to treat colorectal cancer patients, but is often leads patients and survivors to experience a host of symptoms, of which acute emotional distress is a major concern. Smartphone-based meditation via an already-developed app (i.e., Calm) is a unique and novel way of providing a potentially helpful symptom-management strategy to colorectal cancer patients and survivors both during their chemotherapy treatment sessions for the management of distress and between treatment sessions for the management of other more chronic symptoms. Our hypothesis is that colorectal cancer patients using the Calm smartphone app throughout their chemotherapy treatment will see lower psychological distress during individual chemotherapy treatment sessions, greater chemotherapy tolerability, lower chemotherapy toxicity symptoms, lesser fatigue, and higher quality of life as compared to a usual care control group. Colorectal cancer patients (N=30) will be randomly assigned to an intervention (n=15) or control group (n=15) for the duration of their chemotherapy treatment, with study outcome measurement occurring throughout their treatment.
The objective of this study is to determine if treating patients undergoing arthroscopic rotator cuff repair with testosterone will allow patients to accelerate their recovery time after surgery.
Refractory epilepsy, meaning epilepsy that no longer responds to medication, is a common neurosurgical indication in children. In such cases, surgery is the treatment of choice. Complete resection of affected brain tissue is associated with highest probability of seizure freedom. However, epileptogenic brain tissue is visually identical to normal brain tissue, complicating complete resection. Modern investigative methods are of limited use. An important subjective assessment during surgery is that affected brain tissue feels stiffer, however there is presently no way to determine this without committing to resecting the affected area. It is hypothesized that intra-operative use of a tonometer (Diaton) will identify abnormal brain tissue stiffness in affected brain relative to normal brain. This will help identify stiffer brain regions without having to resect them. The objective is to determine if intra-operative use of a tonometer to measure brain tissue stiffness will offer additional precision in identifying epileptogenic lesions. In participants with refractory epilepsy, various locations on the cerebral cortex will be identified using standard pre-operative investigations like magnetic resonance imagin (MRI) and positron emission tomography (PET). These are areas of presumed normal and abnormal brain where the tonometer will be used during surgery to measure brain tissue stiffness. Brain tissue stiffness measurements will then be compared with results of routine pre-operative and intra-operative tests. Such comparisons will help determine if and to what extent intra-operative brain tissue stiffness measurements correlate with other tests and help identify epileptogenic brain tissue. 24 participants have already undergone intra-operative brain tonometry. Results in these participants are encouraging: abnormally high brain tissue stiffness measurements have consistently been identified and significantly associated with abnormal brain tissue. If the tonometer adequately identifies epileptogenic brain tissue through brain tissue stiffness measurements, it is possible that resection of identified tissue could lead to better post-operative outcomes, lowering seizure recurrences and neurological deficits.
For this study, 48 patients who have been diagnosed with COVID-19 will be randomly assigned to four study groups: control, saline, chlorhexidine gluconate, and povidone-iodine. Each patient will be asked to gargle with a solution of either saline, chlorhexidine gluconate, or povidone-iodine or nothing (control group) as well as spray the same solution in their nose four times daily. Patients will then be tested for COVID-19 once daily in the evening for 7 days and viral loads will be measured.
The purpose of this study is 1) to understand effects of COVID-19 crisis on wellness of pulmonary and critical care faculty and trainees who are at frontline fighting this pandemic 2) Assess the effectiveness of series of weekly web based crisis management coaching from world renowned experts in coaching and 3) identify future areas of opportunities in physician wellness
Patients who meet inclusion criteria will be randomized into treatment vs control group. Treatment groups will undergo Hyperbaric Oxygen Therapy (HBOT) and compared to the control group.
The purpose of this research is to see if the DPP4 inhibitor linagliptin, an oral medication commonly used to treat type 2 diabetes,can help with diabetes control and reduce the severity of the COVID-19 infection
This study plans to learn more about the effects of a medicine called baricitinib on the progression of COVID-19 (coronavirus disease of 2019), the medical condition caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Baricitinib is FDA-approved for the treatment of rheumatoid arthritis, an autoimmune condition. This study intends to define the impact of baricitinib on the severity and progression of COVID-19. This drug might to lower the hyperinflammation caused by the virus, which would prevent damage to the lungs and possibly other organs. The study will recruit patients who have been diagnosed with COVID-19. The goal is to recruit 80 patients.
