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 Department of Otolaryngology at Mount Sinai is looking for adults with sinus disease with polyps, otherwise called chronic rhinosinusitis with nasal polyps (CRSwNP). Patients may be eligible to enroll in a study offering a cutting-edge therapy to help reduce symptoms and avoid surgery. The treatment combines an antibiotic (doxycycline) with oral steroids. Oral steroids are the mainstay of medical management for patients with CRSwNP. However, recent studies have shown that doxycycline helps improve symptoms as well by reducing inflammation and killing common bacteria that can cause symptoms. This study is the first to evaluate this combination regimen.
The purpose of this study is to evaluate whether treatment with atabecestat slows cognitive decline compared with placebo treatment, as measured by a composite cognitive measure, the Preclinical Alzheimer Cognitive Composite (PACC), in amyloid-positive participants who are asymptomatic at risk for developing Alzheimer's dementia.
The primary objective of this study is to evaluate the safety of ENTO with VCR in participants with relapsed or refractory B-cell NHL.
This study utilizes the Medication DNA Insight™ tests for pain and mental health medications. We are testing the pain and mental health medications commonly used in pain treatment. Subjects will give a sample of saliva that will be tested for the metabolism of the different medications. Consented providers will be given the results of the test and can determine whether to change the subject's medication regimen. Providers and subjects will be ask to complete surveys both pre and post visits. The purpose is to examine provider and patient satisfaction, confidence and certainty of using the test results.
Today's mobile devices (especially smartphones) are powerful ways to communicate new information to medical researchers. For this study, researchers at Boston Children's Hospital are asking people with hepatitis C to make use of their smartphones to help report information about themselves that may improve how hepatitis C is treated. This study uses a free app called C Tracker that can be installed from the Apple App Store onto the participants iPhone. The main goal of this research study is to use this app to report hepatitis C related health information to the researchers who are conducting this study. The investigators will ask participants about their health,activities, medications, and ways in which hepatitis C has impacted you. This information will be reported anonymously, which means that the researchers doing the study won't know who the participants are.
Conduct a randomized, controlled trial looking at how the use of ultrasound analyzing the inferior vena cava impacts the management and outcomes of pediatric emergency department patients undergoing evaluation and treatment of sepsis and gastroenteritis associated dehydration.
This is a Phase 1b/2a study investigating the safety and efficacy of Sym004, an investigational medicinal product (IMP), in combination with FOLFIRI (chemotherapy) when administered every second week (Q2W).
Patients taking thyroid hormone replacement after thyroid removal surgery often report feeling differently than they did prior to taking thyroid hormone. The symptoms can include fatigue, worsening mood or subjective "brain fog" where the patient feels like their thinking is just not as sharp as it was previously. Multiple studies have found that patients taking thyroid hormone replacement have a diminished quality of life compared to matched controls. Previous studies have suggested that the type of deiodinase (DIO) polymorphism a patient has, which is responsible for converting the thyroid hormone T4 into the more biologically active T3, may contribute to their overall cognition and sense of well-being. The Investigators aim to determine if the type of deiodinase polymorphism a patient has contributes to the patient's cognition and overall sense of well-being after surgery and thyroid hormone replacement. Objective: Determine if patients with the deiodinase type 2 CC polymorphism have objective differences in working memory (N-back test is primary endpoint), cognitive function and sense of well-being after thyroidectomy when placed on standard thyroid hormone replacement therapy. Hypotheses: (1) Patients with the deiodinase type 2 CC polymorphism will have worse working memory (N-back test is primary endpoint), cognitive function and sense of well-being on standard thyroid hormone replacement therapy after thyroidectomy compared with before thyroidectomy. (2) Patients with the deiodinase type 2 TT or TC polymorphism will have no differences in working memory, cognitive function or sense of well-being on standard thyroid hormone replacement before and after thyroidectomy.
The purpose of study is to evaluate the physiologic effects of pulmonary tissue/structural changes associated with COPD and upper airway inflammation on upper airway collapsibility. Upper airway collapsibility is closely associated with development of obstructive sleep apnea (OSA), which is a common disease characterized by repetitive collapse of upper airway during sleep, leading to hypoxemia and arousal. OSA has important neurocognitive and cardiovascular consequences, especially in patients with COPD. Participants in this research study will undergo two overnight sleep studies (PSGs), pulmonary function test, and CT scan of the upper airway and chest. The first sleep study will evaluate the sleep breathing disorder and the second sleep study will measure the upper airway collapsibility, called critical closing pressure (Pcrit). Pcrit is measured by a modified continuous positive airway pressure (CPAP) machine which can provide a wide range of pressures between 20 and -20 cmH2O in order to modify upper airway pressure.
The purpose of this study is to determine whether changing foot strike pattern from a rearfoot strike to a forefoot strike reduces chronic running-related knee pain. It is believed that switching foot strike pattern from a rearfoot strike to a forefoot strike pattern will reduce associated running-related patellofemoral knee pain.
