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 experimental [18F]FLT-PET/CT will be completed before initiation of chemotherapy at either diagnosis or initiation of salvage chemotherapy at relapse and prior to the third cycle (or month) of chemotherapy. Laboratory analysis and correlative radiology, as directed per clinical care based on the primary diagnosis, are required within 30 days of the baseline [18F]FLT PET/CT. Follow-up will comprise 24 months of standard practice treatment and follow up.
The overall objective of this study is to fulfill the Pilot study (miRNA and Myokines Acutely-expressed During Exercise) goal to Investigate the excretion of skeletal muscle-derived miRNA and myokines in patients with pulmonary arterial hypertension during acute exercise that are biologically active and modulate skeletal muscle function during exercise. Pulmonary arterial hypertension (PAH), is characterized by the proliferation of endothelial and smooth muscle cells within the precapillary pulmonary vasculature, if untreated results in increased pulmonary vascular resistance and death. The hallmark perivascular infiltrates in PAH contain inflammatory macrophages and lymphocytes resulting in endothelial dysfunction and involves the dysregulation of distinct inflammatory mechanisms. Idiopathic PAH (iPAH) and scleroderma-associated PAH (SSc-PAH), are related by similar clinical and pathophysiologic features. Patients with PAH experience a central cardiovascular limitation to exercise. Despite effective treatment with pulmonary vasodilators, many resting PAH (rPAH) patients continue to experience exercise intolerance. PAH is increasingly acknowledged as a systemic disease, beyond abnormalities of the pulmonary vasculature. Although other contributions to exercise intolerance in PAH exist, skeletal muscle dysfunction significantly impacts exercise tolerance. The molecular mechanisms behind skeletal muscle dysfunction in PAH remain unclear. Provocative testing with invasive cardiopulmonary exercise testing challenges the cardio-pulmonary-vascular and skeletal muscle systems and elicits a cascade of physiologic events not measurable at rest. Myokines are circulating mediators released from skeletal muscle in an endocrine-like fashion in disease and health influencing many factors but not limited to systemic inflammation, immunity and endothelial function. Myokines have not been well described in PAH. Preliminary data indicate that myokines play important, yet still undescribed, roles in this disease. MicroRNAs (miRNAs) are small non-coding RNA molecules, which negatively regulate gene expression via repressing translation and degrading messenger RNAs through sequence-specific binding. There is a growing literature regarding the biological activity of extracellular miRNAs in PAH and in aerobic exercise. miR-126 has been implicated in skeletal muscle dysfunction in PAH, while miR-133 is skeletal muscle-specific but unlike miR-126 it is not yet implicated in skeletal muscle dysfunction in PAH.
The purpose of this study is to determine whether cannabidiol, relative to placebo, affects subjective response to alcohol or alcohol drinking.
This is a prospective, randomized trial to evaluate tympanoplasty outcomes using Biodesign SIS graft compared to autologous temporalis fascia, the most commonly used graft for repair of tympanic membrane.
Evaluate the safety and tolerability of AMG 553 in adult and adolescent subjects with FLT3-positive R/R AML. Determine the maximum tolerated cell dose (MTCD) or recommended phase 2 cell dose (RP2CD) of AMG 553.
This is a prospective, randomized trial to evaluate canal wall down mastoidectomy (CWDM) healing outcomes using Biodesign® small intestine submucosa graft compared to autologous temporalis fascia graft.
This pilot clinical trial studies how well web-based coping and communication skills intervention works in improving psychological adaptation in patients with gynecological cancer. Web-based intervention, such as coping and communication skills intervention, may help doctors to get a better understanding of ways to help gynecological cancer patients cope with their cancer experience.
This is a single-institution cohort study with two tiers. All participants receive the interventions in Tier 1. Tier 1 is an education study where participants can complete electronic surveys on their pre and post intervention confidence, perform two simulated patient encounters and have their documentation of electronic template monitored longitudinally over 12 months. Participants are free to opt out of any activity related to education assessment or system-based interventions to promote the use of learned skills (e.g. priming or profile feedback). Signed informed consent will Not be required for this tier. Tier 2 includes additional measurements to the Tier 1 activities, and a priming intervention (e.g. provided the names of patients they have have). Participants in Tier 2 complete psychological inventories at three time points to measure emotion regulation and burnout, and participate in a semi-structured interview. after completing the training, they will complete a "priming" intervention. The investigators will require signed informed consent to participate in Tier 2.
The purpose of this study is to test the efficacy, safety, and tolerability of the combination of chemotherapy treatment, which could be either Cisplatin or carboplatin and etoposide, and the research study drug, Pembrolizumab (also known as MK-3475) in patients with high grade neuroendocrine carcinomas of the gastroenteropancreatic system or lung who are chemotherapy naïve. The chemotherapy treatment you receive will be either Cisplatin or carboplatin and etoposide. the participant's doctor will discuss this choice with you and determined which chemotherapy treatment is best for you.
Participants that undergo permanent cardiac pacemaker implantation can often present with challenging anesthetic management plans for the anesthesia provider. Typically, these procedures are performed in electrophysiology labs that are often in remote locations away from the main operating room suite. This presents the logistic challenges of not having standard anesthesia machines, equipment and medications readily available for these cases.Currently, the majority of these cases are done under local anesthesia with light to moderate sedation. However, when it comes to inserting more complex devices such as implantable cardiac defibrillators and cardiac resynchronization therapy devices, participants may not be able to tolerate these more invasive and painful procedures with only local anesthetic as the primary mode of analgesia. Ultrasound-guided regional anesthetic techniques, in particular the pectoralis nerve blocks (PEC I and II) and the Transversus Thoracic Muscle plane block (TTP), offer an alternative mode of analgesia for these participants. PEC I blocks target the lateral and medial pectoral nerves by injecting local anesthetic in the fascial plane between the pectoralis major and minor muscles. PEC II blocks supplement the PEC I block by targeting the intercostal nerves with local anesthetic injected between the pectoralis minor and serratus anterior muscles. The transversus thoracic plane block targets the anterior cutaneous branches of the intercostal nerves. In combination, these four blocks would provide analgesia of the upper anterior chest wall.(3)These would provide effective analgesia of the upper anterior chest wall.(7). However, there is a paucity of studies on the use of PEC blocks in cardiac pacemaker implantation procedures. There is a case report from 2014 on a 71 year-old male with an ejection fraction of 20% undergoing CRTD implantation, which showed that PECs block with moderate sedation using dexmedetomidine could be safely utilized to provide effective analgesia for the procedure.11 However, this was not a subcutaneous ICD that required tunneling of the coils. Thus there are no randomized controlled studies to investigate whether the use of peripheral nerve blocks as primary anesthetic choice could be a viable alternative for multiple participants undergoing subcutaneous ICD placement.
