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 objective of this study is to identify relevant signature gene networks of cardiovascular disease in endothelial cells derived from circulating endothelial progenitor cells of individuals with established cardiovascular disease (CVD).
This is a prospective randomized, clinical trial comparing recurrent use of Morphine Sulfate Immediate Release (MSIR), Oxycodone/Acetaminophen (Percocet), and Hydrocodone/Acetaminophen (Vicodin) at discharge from the emergency department for opioid-naive adult patients presenting with moderate-to-severe pain. At discharge, patients will be randomized to receive either 5 mg of Oxycodone/Acetaminophen (Percocet) tablet 4 times a day for 5 days, 5 mg of Hydrocodone/Acetaminophen (Vicodin) tablet 4 times a day for 5 days, or 15 mg Morphine Sulfate Immediate Release (MSIR) tablet 4 times a day for 5 days. At 1 month, 3 months, and 6 months patients' prescription's history will be accessed by using the DoctorFirst Drug Database to determine the recurrent use that will serve as a surrogate marker of likeability and abuse liability of each prescribed opioid.
Crohn's disease and ulcerative colitis are types of chronic intestinal disorder called inflammatory bowel diseases (IBD) that can affect the small and large bowel causing symptoms of abdominal pain, diarrhea, blood in the stool, and weight loss. Irritable bowel syndrome (IBS) is a milder form of IBD, with symptoms of abdominal pain, bloating, diarrhea or constipation, and blood in the stool. It is not known what causes diseases such as IBD and IBS. This study will look at the events in the gut that leads to leaky gut and inflammation in patients with IBD and IBS. The study will also see if medications such as rifaximin and mesalamine may reduce the amount of leaky gut.
There is concern that pain prescription after outpatient pediatric surgical procedures is excessive and is in excess of patient need. Current practice following pediatric appendectomy is to prescribe all children with 5-15 doses of narcotic pain medication upon discharge regardless of their age, severity of appendicitis, or pain control in the hospital. This study examines the amount of narcotic pain control required by pediatric patients after undergoing appendectomy using a randomized controlled trial study design. Pain control will be assessed with a post-operative pain scale, patient satisfaction survey, and parent satisfaction survey on the days following surgery and at post-operative follow-up. The hypothesis is that the pain scores and patient satisfaction surveys will show no difference in post-operative pain control between the two arms.
The aim of this study is to evaluate whether Hemostatic Agents (HA) make a significant clinical difference in patient outcomes when used for Robotic-Assisted Laparoscopic Partial Nephrectomy (RALPN). The result of this trial will determine whether HAs are necessary for use during RALPN or if they can be omitted from the surgical tools available during this procedure. This study has a direct clinical implication on a patient's outcomes following RALPN, specifically whether patients will have better, worse, or unchanged outcomes with RALPN if HAs are used.
The patient population for this study is individuals requiring high-flow polyurethane tunneled dialysis catheters (TDC) for hemodialysis access. The primary objective of this study is to compare outcomes of participants who undergo left internal jugular placement of a split-tip versus a step-tip versus symmetric tip catheter. This study will review and compare the complication rate and function of the three catheter designs.
As a potential solution to address high rates of depression and anxiety seen in epilepsy patients and poor mental health care access, this trial aims to carry out treatment for depression and anxiety directly in the epilepsy clinic. Patients that meet eligibility criteria, including significant symptoms of depression and/or anxiety, will be enrolled in the intervention. The intervention will consist of an initial prescription for an FDA-approved medication to treat depression/anxiety and telephone-based chronic care management plan for repeated symptom measurement and side effect surveillance. The purpose of this pre-piloting limited study is to streamline recruitment, intervention and outcome assessment process in preparation for a randomized, controlled pilot of the intervention.
The Effectiveness of the Jamboxx Respiratory Therapy Device in Treatment of Patients with Decreased Respiratory Function is a proposal for investigation of the application of gaming to improving respiratory health. The Jamboxx device combines gaming with traditional incentive spirometry to provide users with a fun experience to keep them engaged in their respiratory therapy routine. The device allows users to play a series of mini-games that walk them through their routines. The Jamboxx also records airflow and lung parameters with an external mouthpiece attachment to provide users with real time feedback, and helps to assess increases or decreases in relative lung function over time. The Jamboxx has the potential to significantly impact the field of respiratory therapy by being one of the first gaming devices for patient therapy, and the first respiratory therapy gaming device that is accessible to users with limited mobility. Jamboxx provides a fun and engaging, low cost alternative to the traditional therapy techniques used and aims to improve patient compliance. This study addresses the ongoing challenge of clearing the burden of bronchial secretions resulting from cystic fibrosis. These patients are dependent upon mechanical devices to help clear secretions. A device autonomous means for clearing secretions is well defined in the literature (autogenic drainage) but is difficult to learn. This study proposes to teach cystic fibrosis patients to master autogenic drainage, and seeks to determine at what age it can be taught. As it would be expected that gaming could easily teach adults this procedure, the study will include children for whom learning autogenic drainage based upon conceptualization would be expected to be very difficult.
The investigators' objective is to understand the pathogenesis of diabetes mellitus in Fibrous dysplasia/McCune-Albright syndrome (FD/MAS) by: 1) establishing the contributions of insulin resistance versus impaired insulin secretion, 2) investigating presence of excess glucagon signaling by measuring gluconeogenesis and glycogenolysis, and 3) investigating a potential interaction between diabetes and intraductal papillary mucinous neoplasms (IPMNs).
Myopia has been increasing in prevalence and severity throughout the world over the last 30 years. Increasing levels of myopia are associated with increased frequency and severity of various ocular pathologies. Slowing myopia progression may help to reduce the future risks of these ocular pathologies. Conventional spectacles and contact lenses correct myopia by moving the central focus of the eye from in front of the retina to on the retina centrally. To varying degrees, these lenses allow the light to focus behind the retina, at varying peripheral retinal locations. These findings have led to efforts to design spectacle and contact lenses which correct peripheral hyperopic defocus, to reduce myopia progression. The consensus theory for how both multifocal contact lenses (MFCLs) and orthokeratology can control myopia progression is that they reduce, eliminate, or reverse relative peripheral hyperopic defocus. Existing published studies on the use of multifocal contact lenses to control myopia in humans have utilized lenses with the distance correction in the center with peripheral plus power to correct the peripheral blur. It is possible that one of the mechanisms responsible for myopia progression control with MFCLs is that when the eye is exposed to an image focused on the retina and simultaneously an image anterior to the retina, that this will suppress axial elongation and myopia progression. This mechanism would not be dependent on whether the anterior image is located in the central area of the retina or the peripheral area of the retina. While there are no published human studies demonstrating the effectiveness of near center MFCLs, this author has presented retrospective data showing no differences in myopia progression between near center and distance center MFCLs. Synergeyes, Inc.'s Duette contact lenses are hybrids of rigid gas permeable (RGP) with a silicon hydrogel peripheral portion or "skirt." They now make their MFCLs in both distance center (DC) and near center (NC) designs. This study will analyze the myopia progression of children after being randomly assigned to wear Duette MFCLs or Duette standard single vision contact lenses over a span of two years. Subjects assigned to the MFCL group will wear a DC lens on one eye and a NC lens on the other and will reverse this lens assignment every six months. Refractive changes will be measured by cycloplegic autorefraction and axial lengths will be measured with a laser interference biometer (Zeiss IOLMaster) at six-month intervals.
