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.
1.0 BACKGROUND AND HYPOTHESES 1.1 Osteoarthritis is a continuous and entirely physiologic adaptive process that occurs in every joint. These include the replication of cells that produce matrix, enzymes, protease inhibitors, cytokines, and other peptides. Along with the synthesis of new tissue there is a release of breakdown products into the synovial fluid. Enzymes and phagocytes are required to clear these breakdown products. Normal tissue turnover involves synthesis and breakdown in well-regulated balance. In the degenerative state this balance is upset producing inflammation-derived alterations to the synovium, cartilage, capsule, tendons, and bone. Common causes of such alterations include increased loading, physical stress, and traumatic injury to the joint. 1.2 The rationale for the use of corticosteroids in temporomandibular joint therapy is that they inhibit prostaglandin synthesis and decrease the activity of collagenase and other enzymes that degrade the articular cartilage. Platelet rich plasma is a novel therapeutic agent that has several potential advantages over corticosteroids for the treatment of degenerative pathology of the temporomandibular joint. Platelet rich plasma has been shown to have anti-inflammatory, analgesic, and anti-bacterial properties. It also restores intra-articular hyaluronic acid, increases glycosaminoglycan condrocyte synthesis, balances joint angiogenesis, and provides a scaffold for stem cell migration. Autologous platelet rich plasma injections for treatment of knee cartilage degenerative lesions and osteoarthritis have shown longer efficacy than hyaluronic acid injections in reducing pain and recovering articular function. Similarly, platelet rich plasma has shown to have better outcomes than corticosteroid injections in the management of lateral epicondylitis, and better outcomes than hyaluronic acid injections in the management of osteochondral lesions of the talus. 1.3 Current treatments for degeneration and osteoarthritis of the temporomandibular joint are focused primarily on palliation by reducing inflammation and inflammatory mediators. This study seeks to validate a therapeutic agent that has the potential to actively prevent the progression of degeneration in addition to reducing pain and inflammation
The purpose of the study is to test the efficacy of ATNC05 in the treatment of Atypical Facial Pain (AFP), also known as Persistent Idiopathic Facial Pain (PIFP). This research project targets patients with chronic constant facial pain and excludes patients with primarily paroxysmal pain.
RECTIV® is an ointment containing 0.4% nitroglycerin (NTG) for the treatment of moderate to severe pain associated with chronic anal fissure approved in June 2011 by the US Food and Drug Administration (FDA) for adults. The purpose of this study is to assess the safety, pharmacokinetics, and exploratory efficacy of RECTIV® in adolescents
The purpose of this research study is to learn about the medical effects, safety, and how the Walnut Oral Immunotherapy (OIT) treatment affects your body (immune system). This type of immunotherapy involves giving increasing doses of walnut allergen to gradually build up a person's tolerance to walnut and at least one other tree nut. The goal of the study is to determine whether participants can tolerate (eat) walnuts and at least one other tree nut in their diet after stopping the study therapy.
The purpose of this research is to better understand how calcium and glucose may play a role in people developing diabetes. By doing this study, the investigator hopes to learn whether abnormal calcium and glucose responses in skin biopsies from healthy patients and patients with Type 2 diabetes can identify and predict patients at greatest risk for later complications.
Our primary aim is to determine whether pulsed light therapy (PLT) is effective in reducing symptoms and improving clinical stigmata of dry eye syndrome (DES) associated with meibomian gland dysfunction (MGD) in patients with facial rosacea (which includes ocular rosacea). The uses of PLT are for treatment of rosacea, hair removal, pigmented lesions, and skin telangiectasias. The risks include the potential for transient sunburn-like sensations (i.e. redness, burning sensation) and particularly if not used properly, the potential to cause burns, blistering, scarring, and pigmentary changes.
The purpose of this study is to determine if receiving sub-cutaneous injections of a medication called abatacept causes regrowth of hair in people with alopecia areata. Among patients with alopecia areata, patients with worse disease are unlikely to have satisfactory outcomes with current therapies. Our hypothesis is that Abatacept will be effective therapy in moderate to severe alopecia areata by blocking re-activation of a special type of immunecell call a memory T-Cell (CD8+NKG2D+)thereby blocking the inflammatory response underlying alopecia areata.
Subjects presenting with probable acute coronary syndromes scheduled for cardiac catheterization will be enrolled in this study. Consented subjects will be randomized to receive ticagrelor started with a loading dose immediately after enrollment versus receiving a loading dose of ticagrelor during cardiac catheterization after diagnostic angiography but prior to stenting. Optical coherence tomography (OCT) will be performed after stenting and the volume of thrombus within the new stent will be measured and compared between the groups.
This is an observational, prospective study to evaluate the role of tranexamic acid in reducing blood transfusion in neonates undergoing cardiopulmonary bypass.
Maintenance of adequate anticoagulation or blood thinning is of critical importance when patients are placed on extracorporeal life support, such as extracorporeal membrane oxygenation (ECMO). During ECMO, a patient's entire blood volume is constantly exposed to the artificial surfaces of the ECMO circuit. This exposure activates the clotting cascade, and not only is the circuit at risk for clot formation, but the patient is also at risk for clotting within the body. Hence anticoagulation is vital in allowing the ECMO circuit to support a patient for an extended period of time. Anticoagulation on ECMO is achieved primarily by the use of a blood thinning agent called heparin. Heparin's main mechanism of action is to activate an enzyme called antithrombin III (AT III). AT III deficiency has been shown to be a common finding in pediatric patients requiring ECMO. This deficiency may then result in ineffective blood thinning by heparin. The purpose of this study is to determine how a neonate on ECMO, processes and eliminates a medication called ATryn® from their body. ATryn® is a form ATIII that is made from goat's milk. This will ultimately aid in establishing standardized dosing for the use of ATryn® in this patient population.
