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.
This study is seeking to evaluate the binding of a commercially-available, recombinant human osteoinductive growth factor, rhBMP-2, to a human blood derived product scaffold, enhanced Platelet-rich fibrin (E-PRF), and the release of such a growth factor over time in an in vitro (laboratory) environment. The investigators will compare these release kinetics to those of the FDA approved carrier for rhBMP-2, an absorbable collagen sponge (ACS), a combination of E-PRF and ACS, and E-PRF alone.
This study examines the effects of placebo suggestions tailored to match or mismatch individual participants' motivational styles-an issue of person-situation 'fit' with important effects in public health settings, but which has been ignored in past research.
The purpose of this study is to gain initial experience imaging HNC patient using a new PET camera, a 1mm spacial resolution. The goal is to understand image quality of the system and to see how it works in a clinical environment.
The overall objective of this study is to determine if there are pyloric sphincter abnormalities in patients with gastroparesis symptoms and determine how prevalent these abnormalities are using tests to assess the pyloric sphincter - endoluminal functional luminal imaging probe (Endoflip™), water load satiety testing (WLST), and high-resolution cutaneous electrogastrography (HR-EGG) using Gastric Alimetry™ System.
To determine the correlation between the presence of the arcade of Struthers on preoperative ultrasound and during endoscopic surgery for cubital tunnel syndrome, and to determine the reliability of a portable ultrasound probe to detect the arcade of Struthers in the arm.
Suicidal ideation (SI) associated with major and bipolar depression is commonly seen in a wide range of clinical practice situations including the emergency room (ER). Current treatment regimens are often unsatisfactory. About a third of patients fail to respond to currently available therapy, and there are no currently FDA indicated rapid acting treatments for SI. Suboptimal outcomes have triggered the search for new, well-tolerated and more effective forms of treatment. Small clinical trials suggest that low dose (0.5mg/kg) ketamine is safe and effective for SI. We believe adding music during ketamine infusion may reduce anxiety and lead to more reduced SI based on available evidence. We are testing the hypothesis that a single infusion of ketamine combined with music enhances tolerability and improves outcomes in the treatment of SI when combined with treatment as usual in a factorial study design. One treatment with Ketamine + music will be compared to compared to one-time treatment with ketamine alone, music alone, or treatment as usual. 50 individuals with a depressive episode and suicidal ideation will receive intravenous (IV) ketamine 0.5mg/kg infused over 40 minutes once with 60 minutes of music, 50 individuals will receive IV ketamine without music, 50 subjects will receive 60 minutes of music once, and 50 patients will receive treatment as usual without ketamine or music. We anticipate that the ketamine + music group will have statistically significant indices of improvement in the primary outcome, suicidal ideation scores on the Scale for Suicidal Ideation (SSI) 4 weeks after the ketamine infusion. Secondary outcomes will include depression scores on the MontgomeryÅsberg Depression Rating Scale (MADRS) scale, adverse effects, and SSI scores at the end of 4 weeks. If, as we anticipate, the results indicate success of ketamine + music for SI, the work will identify new opportunities to more effectively manage patients with depression and suicidal ideation presenting to the ER.
The purpose of this study is to compare over the counter and alternative prescription urinary alkalinizing agents to slow release potassium citrate in their ability to modify urinary parameters associated with stone formation.
The current study probes the involvement of the opioid system in placebo effects on social pain, using the opioid antagonist naloxone. 60 participants who recently experienced an unwanted breakup will experience rejection-related stimuli and receive painful heat and pressure stimuli during fMRI scanning. Participants will be randomized to receive either a naloxone or saline nasal spray, and be informed that the spray is either saline, or an effective pain and negative emotion reducing agent.
In this experiment, the investigators study the brain pathways underlying several promising context interventions that enhance the strength of placebo effects. Specifically, the investigators examine the separate and joint effects of two of the most powerful context interventions: Social modeling-observing someone else being effectively treated-and prior treatment success or failure experiences. Participants will be randomized into 4 groups (Social modeling: observed success vs. observed failure and Conditioning: experienced success vs. experienced failure). The objectives are to investigate the placebo effect on pain relief and aversive image stimuli between and within-subjects. Each group will undergo a behavioral induction phase, fMRI placebo test phase, and an identical 3-month follow up fMRI placebo test phase. Follow-up assessment will provide some of the first evidence on predictors of the durability of placebo and context interventions.
This research study is studying Lenvatinib in combination with Pembrolizumab in people with human papillomavirus (HPV)-associated recurrent respiratory papillomatosis (RRP). The names of the study drugs involved in this study are: - Pembrolizumab - Lenvatinib
